Abstract: A paving stone (1) has a linkage securing against displacement. This is achieved by overengaging interlocking elements (6) and underengaging interlocking elements (5) being respectively provided on each side (3, 4) of the paving stone (1).
Abstract: The interconnecting paving stones are provided on at least two opposing sides with outwardly tapering teeth. On one side of said stones, the front sides of said teeth are provided with indentation keys, and on the other side, with indentation grooves. Moreover, the flanks of one row of teeth comprise spacing bosses. An interconnecting paving stone can have the configuration of a rectangular stone and can comprise three teeth on each of its longitudinal sides and either a projection or a recess on the narrow sides.The interconnecting paving stones can be used either for the construction of bicycle lanes with increased smoothness, in which case said teeth engage with each other, or as interconnecting lawn stones, where respective teeth adjoin and interlock by means of said indentation keys and grooves.
Abstract: An arcuate paving block assembly comprising two outer transitional blocks (1) with four arcuate sides, wherein two adjacent sides (10, 18) are curved inwards and the other two sides (19, 20) are curved outwards in order to form a continuous transition from one arc to another; adjacent thereto on both sides an equal number of arc blocks (2, 3, 4; 2a, 3a, 4a) constructed to be mirror images of each other and symmetrical or mirror image shaped keystones of apex blocks (5, 6, 5a, 6a; 7, 7a, 8) which together make up the entire length of an arc, the whole being such that when laid the two outer edges (10) of the transitional blocks (1) enclose an angle of 90.degree. and the height (H) of all the blocks measured at right angles to an imaginary baseline (S) through the lower corner of the transitional blocks (1) is the same.
Abstract: The spacer for the construction of walls from superimposed blocks which have at least one opening on their horizontal sides is provided with a supporting member consisting of four spacing members which are radially symmetrically attached to a holding ring and which are located outside the opening of the block when laid, and with centering means consisting of centering tabs attached to the holding ring. In the case of the spacer for the construction of dry walls, the spacing members are attached to a connecting ring which is linked to the holding ring, the two rings together having a T-shaped cross-section. The centering tabs are each provided with a reinforcement tab extending inwards, which has a T-shaped cross-section together with the centering tab.Such a spacer enables a safe, motionless and torsionally stiff support of the wall blocks and is well suited for mass production.
Abstract: The elements with opening are preferably combined into a lawn plate with openings, whereby these elements with opening are impressed. The plate comprises in its longitudinal direction an indentation whereby a bulge is provided on one side and a narrowing on the other side with a width corresponding to that of an element with opening, and of the paving stone.The individual elements with openings are compatible with paving stones so that these paving stones can be seamlessly adjoined to the element with an opening. When the elements are laid without adjoining paving stones, the plates interlock to provide a pleasant configuration. The arrangement of the individual elements with openings have different dimensions vary within large limits.In another embodiment, the element with an opening is in two parts connected together by a traverse having a smaller thickness.
Abstract: A structural assembly for producing interconnecting structures which includes a first element which, on each of two transversely extending sides lying opposite each other, is provided with a dovetail joint member and, on each of two longitudinally extending sides lying opposite each other, is provided with three fins which, when viewed from the tip or free end, have a convex portion provided on each side with a corresponding, connection recess so that the space between two adjacent fins is identical in form to the fin in order to permit a toothing to be formed. The structural assembly also includes a second element which is provided with a dovetail joint member on one longitudinally extending side and with three fins on the opposite side, as well as a connecting member which has, on each of two sides lying opposite each other, a dovetail joint member which corresponds to the dovetail joint members of the first element.
Abstract: A structural assembly is used for producing walls. The assembly includes a plurality of structural elements, each element having at least one surface defining at least a portion of a dovetail joint. A first one of the elements is parallelepiped in shape and includes a first longitudinal side, the longitudinal side defining a half dovetail groove at each of its ends. The first element also includes a centrally disposed full dovetail groove and a full dovetail tongue separating the full groove from each half-groove. A second element of the assembly corresponds to one half of the first element. A securing element is also provided which includes at least one side defining a dovetail tongue member corresponding to the full groove in the first element. The securing element also includes an aperture extending therethrough. The structural assembly can be manufactured very economically on conventional machines and permits garden walls and the like to be easily produced and also to be secured firmly in position.
Abstract: A structural assembly includes a square trough-shaped stone having inclined external corner regions and a dovetailed groove formed in each wall side. The dovetail tongue of a connecting plate fits into the dovetailed groove. At the lower end of the internal surface of each wall of the stone, a shoulder portion may be provided for accommodating base elements. The height of the connecting plate is advantageously greater than the height of the trough-shaped stone, so that the plate projects beyond the stone in a vertical direction for connection to further stones.With such an assembly, it is possible to erect dry-stone type walls of various types. The individual elements of the assembly can be produced rationally and economically, and it is also possible to produce end elements and corner elements from the trough-shaped stones by cleaving the stones along grooves provided for such purpose.
Abstract: The paving stone comprises a recess which divides the stone into an upper part having a smaller circumference and a lower part with a greater circumference. The lower part, having also a greater height than the upper part, comprises a ribbing or other vertically oriented interlocking means and the upper part can have the appearance of a natural stone. The shape of either the upper or the lower part may be chosen arbitrarily and independent from each other. The molding box for the manufacturing of such paving stones is made of two pieces joined together and comprises the corresponding recess. The lower piece comprises an insert for forming interlocking means.
Abstract: The set of construction units comprises a standard stone, a long stone and a trough stone having a substantially trapezoidal end view, a surrounding groove at the side with the broader base line, on both sides of the surrounding groove a longitudinal slot and at the side with the smaller base line, opposite to each of the longitudinal slots a longitudinal rib. The long stone has dimensions approximately twice as high and about three times as long as the standard stone. Both the standard and long stones have in the surrounding groove a surrounding bead, permitting the stones to be split in half. They also have five holes for making the stones lighter and for permitting these stones to be connected together with reinforced concrete so that they can be utilized as lintels. The trough stone is also twice as high and about three times as long as the standard stone. The closure stone comprises a surrounding bead as well as longitudinal slots.
