Description

FIELD OF THE INVENTION

[0001] The present invention relates to a wall for a building, for instance a house or an apartment building and such like, formed by a number of building elements or blocks, which each are provided with at least one opening, passing through the element from the bottom side to the top side of the element, whereby the building elements are stacked one on top of the other, in such a way that the openings of two elements stacked one on top of the other open into each other, whereby through the openings a rod or cable is lead with at both ends connecting means, by means of which the stacked building elements call be pressed together.

BACKGROUND OF THE INVENTION

[0002] Such a wall is known.

[0003] It is an object of the present invention to provide an improved wall. More, in particular the invention aims to provide a wall which is well able to stand up against earthquakes and such like, which call be built in a relative quick, and simple manner without the necessity to use trained bricklayers and such like, which when necessary can be built up automatically and which can be altered in a relative simple manner as far as the form and the measurements are concerned. A further object is to provide a wall whereby, for instance, in the case of apartment buildings, high pressure forces in the lower concrete layers under the weight of the elements placed above are limited and whereby in this manner the differences in the press-on forces between separate floors are diminished.

[0004] Further the invention aims to provide a wall which is built up of relative light-weight building elements and which, as a result of concrete mixed with polystyrene or another filling agent obtains its U-value (required by building regulations), without the necessity of the application of a cavity.

BRIEF SUMMARY OF THE INVENTION

[0005] The wall according to the invention to that end is characterized in that the rod or cable in an opening is present within a pipe part which is lead through the opening.

[0006] According to a further characteristic of the wall according to the invention the length of the pipe part is the same as a number of times the height of a building element.

[0007] According to yet another characteristic of the wall according to the invention in the wall at a certain level between two layers of building elements a force distribution plate having at least one opening is provided.

[0008] This opening in the force distribution plate has a diameter which is larger than the diameter of a pipe part, while according to another characteristic the opening in the force distribution plate has a diameter which is smaller than the diameter of a pipe part and larger than the diameter of a rod or cable.

[0009] According to a further characteristic of the wall according to the invention a pipe part with one bottom outer end rests on the upper side of the force distribution plate, while the force distribution plate partly rests on a further pipe part present underneath it and partly, through a spring means, rests on a building element present underneath it.

[0010] With this measure it is achieved, for instance, in the case of apartment buildings, that high pressure forces in the lower concrete layers by the weight of the elements placed above are diminished and in this manner the differences in the press-on forces between separate floors are diminished.

DETAILED DESCRIPTION OF THE INVENTION

[0028] As can be seen in the FIGS. 1-8, the wall 1 for a building, for instance, for a house or an apartment building and such like, is formed by a number of building elements or blocks 2, which each are provided with at least one opening 3 passing through the element from the bottom side to the top side of the element. The building elements 2 are, as can be seen in the FIGS. 1, 2, 4, 5 and 6, stacked one on top of the other, in such a way that the openings 3 of two stacked elements 2 come out into each other. Through the openings rods 4 or cables 5 are lead with at both ends connecting means 6, by means of which the stacked building elements 2 can be pressed together. As can be seen in the FIGS. 4 and 5, the rod 4 or cable 5 in an opening 3 is placed within a pipe part 7 which is lead through the opening 3. The length of the pipe part 7 is larger than the height of a building element 2, and preferably the pipe part 7 has a length which is the same as a number of times the height of a building element 2. Each building element 2 is provided with at least two openings 3, passing from the bottom side to the top side of the element.

[0029] The building elements 2 are stacked one on top of the other in a staggered manner, such that the two openings 3 in a building element 2 each come out into the openings 3 in two building elements 2 above it or underneath it. As can be seen in the FIGS. 4, 5 and 6 in the wall I at a certain level between two layers of building elements 2 a force distribution plate 9 having at least one opening 9 is provided. This opening 9 has, in the embodiment according to FIG. 4, a diameter which is larger than the diameter of a pipe part 7.

[0030] In the embodiment according to FIG. 5, this opening 9 in the force distribution plate 8 has a diameter which is smaller than the diameter of a pipe part 7, but larger than the diameter of a rod 4 or cable 5. Further, the pipe part 7 rests with one bottom outer end 10 on the upper side 11 of the force distribution plate 8, while the force distribution plate 8 partly rests on a further pipe part 7a present underneath it and partly, through a spring means 12, in this embodiment a cup spring 12, rests on a building element 2a present underneath it.

[0031] The connecting means 6 of the rod or cable are formed by threaded ends 6, such as is shown in FIG. 6. Thereby at the upper side of the wall 1 and of the rod 4 or cable 5 spring elements 13 such as for instance cup springs 18 are provided.

[0032] In this example of all embodiment the building element 2 is formed out of polystyrene concrete while the side walls are formed out of full concrete.

[0033] As can be seen in the FIGS. 3a, 3b, 3c, 10a and 10b the upper sides and/or bottom sides of a building element 2 are provided at the edges with a groove 13, for instance a trapezoidal groove 13.

[0034] Further the upper side of a building element 2 at the edges can be provided with a groove 13, while the bottom side is provided with a rib 14, having such a shape that it fits with play in the groove 13 of an adjoining element.

[0035] Further the building element can be provided with an opening 15 passing from the bottom surface to the top surface as can be seen in FIG. 4, to provide space for conduits and such like.

[0036] The wall according to the invention consists out of building elements 2 stacked in a staggered manner which are placed on a U-section 16 and a force distribution plate 8, whereby the elements 2 are positioned by means of steel, possibly aluminum, pipes 7 or pipe parts 7, which are stuck through the blocks 2 or elements 2 within which the rods 4 or bars 4, sometimes cables 5, are present. At both ends these are provided with threaded ends 6, by means of which the stacked blocks 2 are pressed together. In some cases instead of bars 4 cables 5 will be used with, at the outer ends, threaded ends; this, in order to allow tightening in a curve along window and/or door frame 17 (FIG. 1). At the upper side of the binding stays/cables 4, 5 in general spring elements 12 such as cup springs 12 are provided to maintain equal the tightening forces in the cables 5 when the walls expand under the influence of changes in temperature. Through each building element 2 always two rods or stays 4/cables 5 are provided.

[0037] Further in the openings 3 pipe parts 7 are provided with a length a number of times the thickness of the blocks, whereby it is recommended to let the pipe parts 7 end in a block 2 and not directly at the upper or bottom side thereof, in order to prevent possible local lateral movement.

[0038] The pipe parts 7 are lead with a play of about 0.5 mm to 1.0 mm through the openings 3 in the building elements 2 within which then also the tie rods 4/cables 5 are present.

[0039] In an embodiment, shown in FIG. 4, the tightening forces in the tie rods 4 as well as the weights of the higher placed building elements 2 such as concrete blocks 2 are transferred to the blocks 2 placed underneath.

[0040] In another embodiment, shown in FIG. 5, the tightening forces in the tie cables 5 and the weights in the higher placed concrete blocks 2 are initially transferred to the force distribution plate 8 after which a part of these forces is transferred to the lower pipe parts 7 and another part is transferred to the lower blocks 2. As far as its magnitude is concerned this last force is determined by the chosen (cup) springs 12 and will minimally be the desired tightening force in the tie cable 5. The pipe parts 7 cannot buckle as the concrete blocks will prevent this. The pipe parts 7 therefore are only loaded by pressure.

[0041] This embodiment is important in case of high buildings such as for instance apartment buildings. To limit pressure forces in the lower concrete layers which are too high as a result of the weight of the higher blocks and to diminish the differences in press-on forces between separate layers, or floors. This embodiment is of relevance for a maximum of three to four living floors.

[0042] With the invention it is possible to build in a simple manner. The pipe parts 7 in the openings 3 of the building elements provide for a positioning or putting in place of the elements 2 or blocks 2 while the tightening of the rods 4 or cables 5 after stacking of the element 2 makes the wall rigid.

[0043] Mechanization and automation sometimes is possible with this method of building because the elements may be transported to their place in the object which is to be built automatically and without the interference of personnel.

[0044] FIGS. 11 and 12 show two embodiments of the wall according to the invention. When manually building a building such as a house, the stiffness of the walls standing in an angle relative to each other is brought about by toothed engaging of these walls, such as can be seen in FIG. 11. According to the embodiment of FIG. 12 the toothing is smoothed away by means of half stones 17 whereby the rigidity of the corners is obtained by means of strips 19 with openings 20 which open into the openings 3 in the building elements and which are applied a number of times per wall height, and whereby the bars 4 pass through the openings 20 in the strips 19.

[0045] The trapezoidal grooves 13 at the upper and bottom side of the building elements 2 are filled during the building with a small amount of cement, which will be less than for instance 5% of the standard amount of the known blocks, or with tight celled sealing rubber/plastic or a given other sealing means with a cylindrical section. With this last embodiment the built up walls are relatively easy to move.
