Description

Grating mat, especially for use in construction, preferably in hydraulic engineering.
The invention relates to a grid mat of intersecting bars, ropes, wires or like strand material of steel or plastic, in particular for use in the construction industry, preferably in hydraulic engineering for soil reinforcement and such coastal and bank protection measures.
Known grating mats are flat moldings that can be transported in the form of pre-manufactured pieces to the place of installation or assembly. The prefabricated pieces are assembled or installed separately, e.g. when using for water or coastal protection, separate pieces must not be joined together, so that a flat covering of the substrate to be protected is achieved. Particularly when used in hydraulic engineering, the grating mats often also have to follow a given course, e.g. of a water soil or other soil, terrain and soil conditions. Such work may be done on the relatively large area pieces of the pre-fabricated grid 20 mats, e.g. a mesh size of 0.5 m, a length of 15 m and a width of 5 m, are carried out only overcoming significant difficulties, which are determined by the maintenance of large area moldings.
Moving individual pieces, in particular under water, is also complicated and difficult by the connection of the individual pieces to a grid mat laid on the water ground. The installation steps are repeated as each individual piece is moved and thus increase the assembly and labor costs by this multiplication.
The object of the invention is to design a grating mat in such a way that it can be moved and installed without problems.
35 Distinguishing an oncoming grid mat. according to the invention, by connecting elements which can be secured to individual strands of the strand material, each of which has at least one strand holding member.
With the aid of the connecting elements, a grating mat can be produced directly at the site of use. Manufacture of a grating mat and its displacement can be successfully performed almost simultaneously. In particular, strand material, for example solid wires with a diameter of about 6 mm, can be rinsed off rolls and thus an almost infinite grid mat can be produced. Only the strands running transversely to the longitudinal direction, which intersect with several longitudinal strands, are cut to size in a length corresponding to the width of the grid mat to be manufactured, and a mutual connection of the strands is effected by means of the connecting elements, e.g. at the intersection places.
The displacement of grid mats is thereby considerably simplified, because the cumbersome maintenance of separate pieces of large surface area to be joined together is eliminated.
In hydraulic engineering, grating mats produced and displaced in this way can also be provided with artificial seagrass, because bundles of 25 plastic strips are attached to the individual longitudinal strands and transverse strands between intersections.
In order that connecting elements can hold the strand material at intersections, each connecting element has at least two holding members. A strand can be held with any retaining member so that a connecting member secures the strands in the region of their intersections. The holding members can of course also be arranged such that two strands running parallel to each other are held without a cross point by a connecting element. A variant with a plurality of retaining members for forming an intersection with several beams is also conceivable. The retaining members can of course be arranged to allow crossings of strand material at any angle.
In a preferred embodiment of the grid 40 mat, it is provided that the holding member comprises a connection: 2 8 4 5 - 3 - ...
thing element is a continuous recording channel continuous through the connecting element.
A recording channel can be easily manufactured, e.g. by making a bore. A pick-up channel 5 also encloses the strand material to be picked up, so that a relatively slip-resistant retention of the connecting element on each strand received in the pick-up channel is present without further special measures. The strand can be introduced into the receiving channel by simple pressing, so that a connecting element can be secured to the respective strands without special tools.
It is further provided that each recording channel extends through the connecting element in a different plane each time. As a result, a problem-free crossing of the strands within a connecting element is possible. The individual strands run straight and no bending in the area of the junction is necessary.
The intersection of the receiving channels within a connecting element is also advantageously provided by the arrangement in different planes.
A particularly favorable embodiment provides that each connecting element is a plastic body. A plastic body can be manufactured inexpensively and is advantageously corrosion-resistant, in particular when the grating mats are used in the field of hydraulic engineering.
Each recording channel is advantageously a groove with narrowed opening edges, which is formed in an associated surface of the connecting element. An open groove makes pressing the strands easier. The narrowed opening edges retain the pressed-in strand and thereby ensure the connecting elements against falling off the strand.
The production of a grating mat directly on the displacement resp. the installation location is further facilitated by the fact that each connecting element is a body composed of two flat discs and that in each Flat disc at least one receiving channel is formed. The strands to be joined together to form a grid mat, namely the longitudinal strands and the transverse strands, can each be separately equipped 40 with the flat disc-shaped half-"5". · V- · - * ts »a Connecting elements and by simply assembling these flat disks, the connecting elements and the grating mat are created at the same time.
It is particularly advantageous that 5 abutting flat surfaces of the flat disc contain connecting members which can be mutually brought into active connection. As a result, the individual flat disks can be assembled into a connecting element without the use of special tools by simply pressing together, the connecting members of which engage on the flat disks.
The connection of the flat disks with strings present in their receiving channels to connecting elements is advantageously fixed, so that the grid mats can no longer fall apart. This is achieved in particular in that recesses and plugs, pins or the like projecting into the recesses are provided as connecting members. In addition, each flat disc has a protruding pin and a recess, which co-act with the corresponding connecting members of the flat discs which can be put on each time.
It is provided that the pin has a cross slit, that the recess is tapered, and that a wedge with a pointed conical shape that can be driven into the cross slit is provided. By driving the wedge during the bringing together of the two flat discs into a connecting element holding together the strings of a grid mat, the pin inserted in a recess will spread and will fit into a fixed pressure seat in the conical cut-out at the back. The advantage of this is that the halves of a connecting element to be joined together are additionally contracted, whereby the connection becomes particularly firm.
The connecting elements can also serve as reinforcement bodies for a grid mat to be sunk under water. For example, e.g. each flat disc in a body of aggravating material, preferably concrete, is included, the flat surface of the flat disc, which is provided with connecting elements, closes concisely with a surface 40 of the body of aggravating material. Just like the construction v 8 v. o • Therefore, a connecting element is a two-piece aggravating body joined together, each half holding a strand of a grid mat and thereby forming junctions or like connections of the strands to form a grid mat without tools or special auxiliary measures . Such a grating mat can be moved immediately.
An aggravating body can e.g. be a concrete stone into which the flat disc is cast. In order for the plastic flat discs to obtain a reliable mounting in the concrete, each flat disc has circumferential anchoring grooves in the region of the circumference.
Each concrete stone is expediently in the form of a * flat half-ball. Composed together, the two half balls in the region of the arrangement of a connecting element for the connection of strand material provide a flat-round concrete stone, the shape of which is particularly effective for the displacement of the grid mat under water, since the roundings have only a small resistance surface to flow, 20 provide ice or similar mechanical forces.
Of course, any concrete stone can also be hexagonal, for example, so that the grating mat with concrete blocks can be combined into a more or less closed covering. The grating mat produced using the connecting elements according to the invention can of course also be combined and displaced with filter mats, filter mats, non-woven fabrics or similar fabric mats also being held by corresponding connecting elements, which also simultaneously form the individual strands into a grating mat. connect.
The connecting elements can be used with or without weighting bodies, so that grating mats can be manufactured in any embodiment. Special designs for adaptation to the respective mounting location can readily be realized already during manufacture and displacement.
Embodiments illustrating further features of the invention are shown in the drawing.
For example: 40 Fig.1 shows a schematic top view of a part. Η o a k 3 -6- of a composite grid mat,
Fig. 2 is a side view of an intersection of two strands in a grid mat with connecting elements and weighting bodies in section,
Fig. 3 is a side view of a half of a connecting element in section,
Fig. 4 shows the top view of half of the connecting element according to Fig. 3, Fig. 5 a cross-sectional view of a half connecting element, which can be used without a weighting body,
Fig. 6 shows a simplified embodiment of a connecting element in side view, Fig. 7 a top view of the connecting element according to Fig. 6 and
Fig. 8 a sectional view of a connecting element for rectified connections of strand material.
Fig. 1 shows a cut-out part of a grating mat shown in top view. The grid mat consists of longitudinal strands 1 and transverse strands 2, for which e.g. steel wire with a diameter of 6 mm can be used. The longitudinal strands and the transverse strands are put together and connect at the intersections 3 to connecting elements 4, so that a grid mat is formed, the mesh width of which e.g. Can be 0.5 mm. The grid mat can be equipped with artificial seagrass 5, which here consists of bundles of synthetic fibers attached to the strand material.
The connecting elements 4 can also serve as weighting bodies for the grid mat.
Fig. 2 shows a connecting element 4 designed as an aggravating body in a schematic cross-sectional view. The connecting element is essentially a plastic body, which consists of two composite flat discs 6 and 7. Each flat disc has a holding member designed as a receiving channel 8 for a strand of the strand material, as a result of which a transverse strand 2 for the flat disc 7 and a longitudinal strand 1 is held by the flat disc 6. Both flat discs have recesses £ 5 0 9 3 ii § -η - - ..: 9, 9a, in which protrude from the other flat disc protrude the pins which during pressing of the two flat discs against each other wedges 10, 10a driven into the pins are spread apart. The two flat discs, each holding a strand of the grid mat, are thereby firmly connected to each other in the region of a cross region of the strand material to be formed.
In this exemplary embodiment according to Fig. 2, each flat disc is additionally cast in a weighting body 11 and 11a, respectively, which has the form of a flat half-ball. The aggravating bodies exist e.g. made of concrete and are designed in such a way that together with the flat discs 6 and 7 they form a cohesive round body after being joined together.
In Fig. 3, the flat disc 6 is again shown in a cross-sectional view. For improved anchoring in the weighting body material, a circumferential anchoring groove 12 is formed. A protruding pin 13 and the recess 9 represent the connecting members, which can be brought into working connection with corresponding connecting members of the other flat disc (Fig. 2). As shown, the recess 9 is cut back conically and has the protruding wedge. 10.
The pin 13 is provided with cross slits. The pin 13 engages in the corresponding recess of a flat disc (flat disc 7 in Fig. 2) and the wedge 10 thereby drives the crevices of the pen apart, so that each pin with a push seat in the conically recessed recess 9 of the flat disk is always different. At 8a, again, the receiving channel means for a strand of strand material forming the grid mat.
Fig. 4 shows a top view of the flat disc 6, showing how the recording channel 8s runs through the flat disc. The receiving channel is constructed as a groove, which is provided with narrowed opening edges 14, 14a.
Figure 4 clearly shows the cross-splitting of pin 13.
Each flat disc 6, 7 can be cast in concrete. As a result, each connecting element can be used as an aggravating body or as a concrete stone, e.g. for a covering, serve 40.

In Fig. 5 another embodiment of a connecting element is shown, again showing only one half of a connecting element corresponding to a flat disc. A connecting element composed of such halves is made of plastic and serves to connect the strand material from which a grid mat can be assembled. With 9a again a conical recess is indicated and with 13a a corresponding pin. A strand can be received in the retaining member configured as a receiving channel 8a. After joining together two corresponding halves according to Fig. 5, a connecting element is formed which connects two intersecting strands.
Fdg.6 shows a particularly simple embodiment of a connecting element, which is designed as a plastic disc 16, in which two intersecting receiving channels 8c and 8d are formed. The receiving channel 8c clearly shows its shape as an open groove with narrowed opening edges.
The connecting element in its simplified form is made of plastic and can e.g. as a releasable mounting aid are used in the manufacture of grating mats.
Fig. 7 shows a top view of the simplified connecting element according to Fig. 6.
Fig. 8 shows a further embodiment of a simplified connecting element in cross section. In this exemplary embodiment, the take-up channels for strand material do not intersect, but run parallel, so that with the connecting element shown in Fig. 8, straight connections can be secured between two strands of a grid mat.
