Definitions
- the invention relates to a spacer for a reinforcement made of two parallel and spaced steel mats.
- spacers are arranged between the structural steel mats in order to keep them at a predetermined distance from one another.
- the spacers are not arranged sufficiently firmly, so that they fall over under loads such as occur frequently in concrete construction and can no longer fulfill their purpose.
- the object of the invention is to provide a spacer which is arranged sufficiently firmly between the structural steel mats and maintains the predetermined distance between the structural steel mats of the reinforcement even under load.
- this object is achieved in that the spacer consists of a plurality of spaced elements arranged one behind the other and side by side, which are connected in a snap-in manner to a first reinforcing steel mat and hold a second reinforcing steel mat at a distance from the first reinforcing steel mat.
- the spacers according to the invention can be installed in a simple manner, since the spacer elements can be inserted in the compressed state between adjacent links or elements of the first structural steel mat and the snap-in connection is produced by simply releasing them.
- the latching connection results in a sufficiently firm arrangement of the spacing elements between the first and the second structural steel mat, which are thereby securely held in their predetermined distance even under loads.
- Figure 1 is a perspective view of a reinforcement with the spacers according to the invention. 2 shows a view of an angular element in the installed state with a spacer element of the reinforcement according to FIG. 1;
- FIG. 3 shows a view of a locking element in the installed state with a spacer element of the reinforcement according to FIG. 1;
- FIG. 4 shows a side view of a modified embodiment of a spacer element in the reinforcement according to FIG. 1.
- Fig. 1 shows schematically a perspective view of a section of a reinforcement for concrete as a building material.
- Such reinforcement consists of a first, namely lower structural steel mat 6 and a second, namely upper structural steel mat 7, which are arranged at a distance from each other essentially parallel and are kept apart by spacers.
- the spacers are formed from spacer elements 20 which are arranged in rows one behind the other and next to one another.
- each spacer element 20 is made of resilient material, in particular reinforcing steel, in such a way that they can be assembled in a particularly simple manner.
- each spacer element 20 consists of two angle elements 21 and an angle element arranged or centered therebetween, which is designed as a latching element 22.
- a different numerical ratio between the angle elements 21 and the locking elements 22 can also be selected.
- the angle elements 21 and the locking element 22 enclose essentially the same angle, which is adapted to the respective application or the respectively existing distances in the first structural steel mat 6.
- the latching element 22 is designed such that it snaps into two adjacent elements 10 and 11 of the first structural steel mat 6.
- the angle elements 21 and the locking element 22 are connected at their tips by a strut in the form of a steel rod 12 and near their free ends by struts in the form of steel rods 13 and 15.
- the free ends of the angle elements 21, cf. Fig.2, are each provided with a protective device, which consist of plastic feet 4 in the illustrated embodiment.
- the free ends of the angle elements 21 stand on a casing 16 with the plastic feet 4.
- the plastic feet 4 not only prevent the free ends of the angle elements 21 from penetrating into the casing 16, which is usually made of wood, but also prevent the corrosion of the angle elements 21 at the projecting free ends.
- the latching element 22 is provided at its free ends with a latching part, which establishes the latching connection between the spacer element 20 and the first structural steel mat 6.
- the locking parts are formed from hook-shaped bent free ends 14 of the locking part 16.
- the latching parts can also be formed by angled latching parts 2 of the latching element 22. In it, the free ends are angled so that after they snap into place on the adjacent elements 10 and 11 of the first structural steel mat 6, they do not run parallel to this structural steel mat 6, but at an angle directed to this structural steel mat 6.
- the spacer elements 20 are pressed together, so that the free ends of the latching elements 22 with the latching parts 2 and 14 are passed between the adjacent elements 10 and 11 of the first structural steel mat 6; the plastic feet 4 of the angle elements 21 then stand on the casing 16.
- the latching parts 2 and 14 of the latching element 22 engage under the adjacent elements 10 and 11 of the first structural steel mat 6. Due to the bending of the free ends of the latching element 22 to the latching parts 2 and 14, these latching parts are located on a level above the casing 16 so that the ersce mild steel mat 6 is lifted from the casing 16 after the spacer elements 20 have been attached.
- each of the adjacent elements 10 and 11 of the structural steel mat 6 is located between the associated latching part 2 or 14 of the latching element 22 and the associated strut 13 or 15, which the angle elements 21 and the latching element 22 close to their free Connects ends together.
- the spacer elements 20 can have further struts or steel rods 17 or 5, which connect the adjacent angle elements 22 of each spacer element 20 to one another either laterally or diagonally in the region between the tip and the free ends, cf. Fig. 4.
- the second structural steel mat 7 can be connected in a conventional manner to the tips of the spacer elements 20.
- the locking elements 22 of the different spacer elements 20 can be arranged in a modification of the embodiment shown in Fig.1 so that the locking elements 22 within a series of spacer elements 20 are alternately connected to the first and second structural steel mat 6 and 7 snap.
- the arrangement can also be such that adjacent rows of spacer elements 20 contain locking elements 22, which are connected in a row with the first structural steel mat 6 and in the adjacent row with the second structural steel mat 7. .
