It is disclosed a timber building element for building-up a wall, which comprises: a body formed as a profile block having two lateral sides and also an upper connecting face, a lower connecting face and two end connecting faces; a longitudinal tongue (2, 4) on the upper or lower connecting face and one of the end connecting faces; and a longitudinal groove (3, 5) on another upper or lower connecting face and another end connecting face. The longitudinal tongue (2, 4) and the longitudinal groove (3, 5) are laying in one plane that is parallel to planes, which the lateral sides are laying in, and have forms and sizes corresponding one another. End connecting faces are inclined unidirectional and wave-like curved, wherein an uppermost portion of a wave-like curvature of the wave-like curvature is located higher than a lowermost portion of the wave-like curvature of this end connecting face, and forms and sizes of inclinations and the wave-like curvatures of the end connecting faces correspond one to another. Also, it is disclosed a wall built-up of the present timber building elements providing reliability and integrity of the wall as a whole.
The invention relates to a building industry, namely to timber building elements and wall constructions built-up of such elements. The invention can be used for construction of new small and low-rise buildings as well for reconstruction thereof.
BACKGROUND ARTThere are known different timber building elements in form of a timber having cross-sectional dimensions less than a length thereof and provided with connecting elements for joining timbers one with another when building-up a wall of such the elements [for example: DE2802275A1, 27 Jul. 1978; RU2250312C2, 20 Apr. 2005; U.S. Pat. No. 4,330,973A, 25 May 1982; WO89/11008A1, 16 Nov. 1989]. However, as such the timber building elements are joining one with another by considerably long upper and lower connecting surfaces when the elements are laying one to another in rows, reliability of such joints is low, taking in consideration deformations of different kinds which present in a built-up wall or elements thereof. In addition, to fabricate these building elements, it is required to use a row long-cut wood having a high quality along all length thereof. Such building elements also have such disadvantage as a high labor intensity due to necessity to perform many manipulations with large-sized elements having sufficiently large weights.
As a more detailed example, it is known a panelized log home construction, wherein a wall panel comprises a plurality of logs of predetermined length stacked on a top of each other [CA 2541653 A1, 09 Oct. 2006]. Tongues are machined on log ends such that, when stacked the logs, the tongues are entering into wall receiving grooves of posts framing the wall panel from both sides. An upper side of each of the logs is provided with a longitudinal tongue having a rectangular cross-section, and its lower side is provided with a longitudinal groove having a corresponding cross-section. When stacking the logs, the longitudinal tongue is entering into the longitudinal groove, thereby forming a continuous wall structure. Sealing materials can be laid between the logs stacked on each other, and the logs are fastened by long screws along a length of a joint therebetween. This technical solution has all of the above-mentioned disadvantages.
Also, it is known a timber building element made of a laminated edged board provided with a V-shaped tongue on an upper board edge and a corresponding groove on a lower board edge [RU 28878 U1, 20 Apr. 2003]. This building element allows to manufacture a box-like timber by using two edged boards, wherein an internal space, limited by upper and lower spacers installed along a length thereof, is filled in with a thermal-insulating material, and end faces of the box-like timber are closed by plywood sheets. These box-like timbers can be used for building-up a wall of a low-rise timber house by means of inserting a V-shaped tongue of one box-like timber into a V-shaped groove of another box-like timber. In addition to the above-mentioned disadvantages, this timber building element has such a disadvantages as a high cost because of using different assembly operations when manufacturing the box-like timber.
Meanwhile, in the prior art, it is know a knockdown panel made of a small-sized timber building elements, each of which has a structure of a laminated wood brick composed of two laminated boards arranged symmetrically and spaced from one another by spacers [KR 10-2006-0025321 A1, 21 Mar. 2006]. Herein, particularly, a building element is manufactured from two edged board pieces set on their edges and fastened with each other by a lateral sides thereof. This building element is chosen as a prototype of the present invention. Upper, lower and end edges of the edged board pieces, composed this building element, are displaced in such a manner that it is formed a joining element such as a double tenon on an upper portion and one of back faces, and such as a double groove on a lower portion and another of the back faces. These building elements are used for manufacturing a two-rows wall panel by inserting the tenon of one building element into the groove of another building element, wherein the wall panel can further comprise spacers, tightening devices provided with channels for mounting thereof and so on. There are disadvantages of this known timber building element as follows: complex technology of manufacturing due to necessity to use assembly operations; poor reliability and low tightness of joints between the building elements due to using a rectangular cross-section of the tenons and the grooves, that require usage of additional sealing materials as well as additional tightening devices to tighten a wall panel of these building elements along the vertical as well as the horizontal.
DISCLOSURE OF INVENTIONA technical problem to be solved by the present invention is providing a small-sized timber building element, which can provide reliability and integrity of a wall built-up of such elements, particularly by providing reliable and tight joints between adjacent timber building elements of the wall, which allow to compensate different kinds of deformations.
Another technical problem to be solved is simplification of a manufacturing process of timber building elements by excluding assembly operations.
Still another technical problem to be solved is simplification of a design of a wall of small-sized timber building elements by using the only vertical force for pressing joints between the timber building elements, particularly by a force of weight the timber building elements as well as constructions supported on the wall from above.
To solve the technical problem, in one aspect, it is presented a timber building element for building-up a wall, which comprises: a body formed as a profile block having two lateral sides and also an upper connecting face, a lower connecting face and two end connecting faces; at least one longitudinal tongue provided between the lateral sides on one of the upper and lower connecting faces and one of the end connecting faces; at least one longitudinal groove provided between the lateral sides on another of the upper and lower connecting faces and another of the end connecting faces, wherein the longitudinal tongue and the longitudinal groove are laying in one plane that is parallel to planes, which the lateral sides are laying in, and a form and sizes of the longitudinal groove correspond to a form and sizes of the longitudinal tongue. This is new, that each of the end connecting faces is inclined and wave-like curved, wherein: both of the end connecting faces are inclined unidirectional; an uppermost portion of a wave-like curvature of the end connecting face is located higher than a lowermost portion of the wave-like curvature of this end connecting face; and a form and sizes of an inclination and the wave-like curvature of one of the end connecting faces correspond to a form and sizes of an inclination and the wave-like curvature of another of the end connecting faces.
The above-mentioned form of the end connecting faces allows to achieve high reliability of joining between the timber building elements not only in a longitudinal direction, with preventing a longitudinal relative displacement, but also in a vertical direction by alignment these timber building elements, having natural dimension and form instability, in a wall blockwork by means of using the inclined and wave-like curved end connecting faces. Here, to press all joints between the timber building elements, it is enough to apply a vertical compressive force to a wall of these building elements, and it can be enough a weight of the building elements together with constructions supported on the wall from above to create such compressive force.
It is preferred, if an upper portion and a lower portion of the end connecting face are inclined, and a middle portion of the end connecting face is wave-like curved. And it is more preferred, if the end connecting face has a sinusoidal form.
It is preferred, if a length of the lower connecting face is more than a height of the timber building element which is measured between the upper and lower connecting faces, and the height is more than a width of the timber building element which is measured between the lateral sides, wherein the length of the lower connecting face is equal to a length of the upper connecting face.
The wave-like curvature can form at least one apex and one through. And the apexes and the throughs of surfaces of the wave-like curvature can be displaced down or up from a central longitudinal axis of the lateral side to allow to prevent edge splintering during processing the timber building element. Herein, it is more preferred, if a value of a displacement of the apex and the through from the central longitudinal axis of the lateral side is not more than 1/10 of a height of the timber building element which is measured between the upper and lower connecting faces.
An inclination angle of the end connecting face can be 30-89° in relation to the horizontal.
The timber building element can comprise two or more the longitudinal tongues and a corresponding number of the longitudinal grooves which are arranged parallel with each other at regular intervals from one another.
From a point of view of aligning the timber building elements in a wall blockwork and increasing a degree of tightness of joining between the timber building elements, it is preferred, if the longitudinal tongue and the longitudinal groove have a triangular or trapezoidal cross-section, particularly in a form of an isosceles trapezium or triangle. Herein, a slope angle of lateral sides of the triangular or trapezoidal cross-section can be 20-70° in relation to the vertical.
One of the lateral sides can be provided with a mortise for fixing secondary members of the wall, for example, for installing an inter-row spacer in the mortise, which can be used in a two-rows wall blockwork of the timber building elements in accordance with the present invention.
From a point of view of quality of a built-up wall, it is preferred, if the timber building element is made of uniform timber dried by air-seasoning, and also if the body, the longitudinal tongue and the longitudinal groove are formed integrally with one another.
In addition, to solve the technical problem, in another aspect, it is presented a wall built-up of timber building elements having the same form and sizes, each of which is formed as a profile block and provided with a longitudinal groove on two adjacent connecting faces thereof and a longitudinal tongue on two another adjacent connecting faces thereof, wherein the timber building elements are laid tightly one close to another in a wall blockwork in such a manner, that the longitudinal tongue located on an upper connecting face of one of the timber building elements is fitted into the longitudinal groove located on a lower connecting face of an adjacent timber building element. This is new, that the wall is built-up of the timber building elements described above.
The can further comprise a tightening device pressing the wall blockwork along the vertical.
It is better, if joints between the end connecting faces of the timber building elements of one tier of the wall blockwork are displaced in relation to joints between the end connecting faces of the timber building elements of another adjacent tier. This design increases strength properties and integrity of the wall.
It is preferred, if joints between the end connecting faces of the timber building elements of one tier of the wall blockwork are displaced in relation to joints between the end connecting faces of the timber building elements of another adjacent tier by a displacement value that is not less than a length of the joint between the end connecting faces of the timber building elements which is measured along the horizontal, up to a half of a length of an upper or lower connecting face.
The wall can further comprises a bearing timber bar, laid tightly under a lower tier of the wall blockwork, and a pressure timber bar, laid tightly on an upper tier of the wall blockwork.
The timber building elements can be laid in the wall blockwork in two rows with forming an internal space therebetween, and inter-row spacers is installed between the rows of the wall blockwork.
In the last variant, the wall can comprise at least several pairs of the timber building elements, each of which is provided with a mortise arranged in one of the lateral sides thereof, wherein each of the pairs of the timber building elements provided with the mortises are laid in different rows of the wall blockwork opposite one another with oppositely facing the mortises thereof, and ends of each spacer of the inter-row spacers are inserted into the mortises of each of the pairs of the timber building elements provided with the mortises, respectively. Herein, it is preferred, if the ends of the spacer are inserted into the mortises of the pair of the timber building elements with possibility to move along the vertical.
The above-mentioned wall of two or more rows can further comprise a tightening device including pulling ropes which are arranged vertically inside the internal space to press the wall blockwork along the vertical completely.
In the last variant, it is preferred, if the tightening device further includes supporting fasteners, mounted in a base of the wall blockwork, and clamp plates, supported on an upper tier of the wall blockwork, wherein low ends of the pulling ropes are fastened to the supporting fasteners, and the upper ends of the pulling ropes are fastened to the clamp plates.
In the above-mentioned wall of two or more rows, the internal space can filled in with a thermal-insulating material and/or a sound-insulating material, for example, such as sawdust.
The wall can be provided with an opening, for example, such as a door opening, a window opening, a process-oriented opening and another opening.
In the last variant, the wall can further comprise a discharging piece, spanned the opening and made of a squared timber having a cross-section matched with a cross-section of the timber building element, wherein at least one end face of the squared timber has a form and sizes corresponding to a form and sizes of the end connecting face of the timber building element. Herein, another end face of the squared timber can also has a form and sizes corresponding to a form and sizes of the end connecting face of the timber building element or can be perpendicular and provided with a longitudinal tongue of a dovetail type to form a corner joint with another wall or a partition.
The wall can be provided with a corner joint for joining with another wall or a partition. This corner joint can be formed as a dovetail mail joint.

The present invention will be further explained on examples.
A timber building element 1 formed as a profile block, which an embodiment is represented in
It is preferred, if sizes of the building element 1 have following proportions: a length (L) of a lower connecting face is more than a height (H) of the building element, which is measured between upper and lower connecting faces and is more than a width (B) which is measured between lateral sides of the building element 1. Herein, the length of the lower connecting face must be equal to a length of an upper connecting face.
For example, for the building element 1, designed for building-up a wall of a wood conduit such as a private bath house, that will be described below in details, sizes can be: the length L=450 mm; the height H=110 mm; and the width B=50 mm. In this example, the building element 1 is similar to a common building brick when laying the brick as a stretcher, i.e. when laying the brick on its more long and more narrow face.
There are connecting elements located on the upper and lower connecting faces as well as end connecting faces of the building element 1, namely: an upper double tenon, comprising two parallel longitudinal tongues 2 on the upper connecting face and two longitudinal tongues 4, conjugated therewith, on a left end connecting face; and a lower double groove, comprising two parallel longitudinal grooves 3 on the lower connecting face and two longitudinal grooves 5, conjugated therewith, on a right end connecting face. Here, the terms “left” and “right” are used in accordance with orientation of the connecting faces, as they are shown in
The pair of the longitudinal grooves 3, 5 and the pair of the longitudinal tongues 2, 4 are laying in two parallel planes, respectively, which are parallel in turn to planes, which the lateral sides of the building element 1 are laying in.
In this example, a slope angle β of lateral sides of a cross-section of the longitudinal tongues 2, 4 as well as the longitudinal grooves 3, 5 is 30° and, in general, it can be chosen from a range from 20 to 70°. As it shown in the
The end connecting faces of the building element 1 are inclined unidirectional and wave-like curved in middle portions thereof in a form of a sinusoidal wave comprising two half-ways. A form and sizes of an inclination and a wave-like curvature of one of the end connecting faces are matching with those of another end connecting face.
In this example, an inclination angle α of the end connecting faces is 45° and, in general, it can be chosen from a range from 30 to 89°.
Apexes and throughs of surfaces of the wave-like curvature are displaced from a central longitudinal axis of the building element 1 by a distance e that can be not more than 1/10 of the height H to decrease edge splintering during processing the building element 1.
As it is shown in
As it is shown in
In a wall blockwork, the longitudinal tongues 2 and 4 are fitted into the longitudinal grooves 3 and 5, and the end connecting faces are joined tightly in the wall blockwork by overlapping wave-like curvatures, matching with on another, with forming interlocking joints, which do not require additional connecting means, such as a glue or fixing elements, as well as do not require additional sealing materials.
Such the interlocking joints of one tier of the wall blockwork of the wall 6 are displaced in relation to interlocking joints of another tier by a half of the length L of the building element 1, that is 225 mm for the above-mentioned sizes of the building element.
The rows of the wall 6 are spaced from one another by the inter-row spacers 8, and an internal space 11 is formed therebetween.
Holding boards 12 are laid on upper tiers of each of the rows of the wall blockwork, and metal clamp plates 13 of the tightening devices 14 are installed thereon, wherein the tightening devices comprise pulling cable-laid ropes.
The pulling cable-laid ropes of the tightening devices 14 are arranged vertically inside the internal space 11 and spaced from one another by a specific distance, for example by an equal spacing.
Low ends of the pulling cable-laid ropes of the tightening devices 14 are fastened to the anchors 15 of the concrete foundation 10, and an upper end of each of the pulling cable-laid ropes is fastened to the clamp plates by means of its threaded end passed through the clamp plate 13 with a rubber damping element 16 and fixed by a claw nut 17 via a ring plate, thereby allowing to tighten all joints between the building elements 1 and to provide integrity of the wall blockwork of the wall 6.
A blanket water isolation 18 of tree layers of a rubberoid are placed between the bearing timber bars 9 and the concrete foundation 10.
The inter-row spacers 8 can be formed of a metal tube, and they can be located by a height of the wall 6 with spacing apart from one another by an equal number of tiers of the wall blockwork, for example through every two tiers of the wall blockwork, and can be located by a length of the wall with spacing apart from one another by an equal number of the building elements, for example through every one building element 1.
Ends of the inter-row spacers 8 are provided with metal plates, weld perpendicularly thereto, by means of which the inter-row spacers 8 are inserted into the vertical slots of the mortises 7, which are located on internal (from a side of the internal space) lateral sides of the building elements 1. Herein, the ends of the inter-row spacers 8 are installed into the mortises 7 with possibility of a vertical displacement limited by the height H of the building element 1 in a plane of the wall 7, which can take place as result of deformations of the building elements 1 in the wall blockwork, for example due to seasonal changes of temperature-humidity conditions between outdoor and indoor environment, due to natural non-uniform shrinkage of the building elements 1 and so on. Here, the vertical displacement of the inter-row spacers 8 can compensate internal stresses, accumulating in the wall 6, and to distribute the stresses uniformly between rows and tiers of the wall blockwork.
In the internal space between two rows of the wall blockwork of the wall 6, there can be mounted pipelines of a ware-supply system or a heating system and also laid in electric cables (not shown).
As thermal- and sound-insulating materials to be filled in the internal space 11 of the wall 6, there can be used sawdust or wood-flakes which are ecologically-clean mill debris of processing the timber building elements 1.
To prevent sweating in the thermal-insulating material, the internal space of an external wall can be provided with a vapor barrier of an aluminium foil.
Depending on locations of the wall 6 in a building, the building elements 1 can be used for building-up external walls provided with door, window and/or process-oriented openings, as well as for internal walls or partitions provided with door or process-oriented openings only.
The wall 6 can be provided with corner connection means, i.e. corner joints, to be connected with another walls and partitions, at this, in corner joints located outdoor of a building as well as in window and door openings, it is preferred to form the corner joints as dovetail joints.
For corner joins located indoor as well as butt corner joints, it is preferred to form the corner joints by abutting to interfaced walls and partitions as divided tenon joints on abutting surfaces, thereby providing fail-safe joining thereof (not shown).
Window and door openings can be spanned by discharging pieces 19 made of a squared timber having a corresponding length as well as a cross-section, which provide a fail-safe support thereof on the wall blockwork of the wall 6, wherein end faces of the squared timber have a form and sizes corresponding to a form and sizes of the end connecting faces of the building element 1. Herein, one of the end faces of the squared timber can be provided with a longitudinal tongue of a dovetail type to form a corner joint with another wall or a partition, as it was described above.
An intermediate pull-rod 20 can be installed in the internal space of the wall 6 to tighten the interlocking joints between the building elements 1 in a part of the wall blockwork above the discharging piece 19 in addition.
Visible lateral sides of the building elements 1 can be provided with a decorative woodcarving pattern to enhance aesthetic perception of a pattern of the wall blockwork of the wall 6, which is formed by the wave-shaped interlocking joints between the building elements 1.
It should be understood, that the above examples were used for illustrative proposes only to demonstrate possibilities to carry out the present invention and some advantages thereof, and these examples do not intend for limitation of a scope of protection that is determined by the appended claims, and those skilled in the art are able to carry out another embodiments of this invention within the scope of protection.
