Description

6006375-3 solar forces, of which the piles are actuated via the inclined rods are absorbed by the rod and whereby the load from the wall can be introduced centrally in the piles.

The invention is described in more detail below in connection with a pair of embodiments and the accompanying drawing, in which - Fig. 1 shows a vertical section through a wall with a first embodiment of a device according to the invention and - Fig. 2 correspondingly shows a part of a second embodiment of a device according to the invention.

According to. According to the invention, there are pairs 1,1 of opposite piles 1 arranged in connection with the wall 2 of the building, i.e. opposite each other on both sides of the wall.

In the wall 2 in connection with said pair 1,1 there are inclined holes 3 drilled either obliquely downwards, as in Fig. 1 or obliquely upwards in the direction from the top 7 of the piles 1. In each hole 3 there is a steel rod -1 inserted and fixedly injected, which rods Ä are connected to the top 7 of each pile 1, whereby anchoring in the pile top 7 takes place with a steel plate, beam or the like.

Between the top 7 of the piles 1,1 there is a hole 5 drilled through the wall 2, in which a steel rod 8 is inserted and fixedly injected, which is anchored in the top 7 of the piles. Fig. 2 shows an embodiment in which the rods Å are provided with an anchoring plate 6 in the lower end of the rods.

The function of the device according to the invention and the method should be substantially stated above. The load from the building is thus transferred to the piles 1 by means of the bars Å, 8. The horizontal forces, of which the piles are actuated via the inclined rods Å, are absorbed by the rod 8, whereby the load Q from the wall 2 can be introduced centrally in the piles 1.

In this case, the rods are anchored in the top 7 of the piles so that this is possible.

By tensioning the steel bars with jacks, the load from the building can be applied to the piles without settling of the building. Through such bias, test loads of the piles can also take place. A couple of embodiments of the invention have been described above. Of course, more embodiments and minor changes are conceivable without departing from the inventive concept. According to. the embodiments shown here thus cross the rods Å each other in the wall 2. Furthermore, acc. what is shown here are the angles C§ (1, (§ (2), which are formed between the rod 8 and the respective inclined rod Ä are different. Furthermore, according to the exemplary embodiment, the rod 8 is not horizontal, i.e. the pile tops 7 are at different levels.

The invention is not to be construed as limited to the embodiments set forth above, but may be varied within the scope of the appended claims.

Claims (8)

8006375-3 Claims claim Procedure for basic reinforcement of existing structures, where pairs of opposing piles are arranged adjacent to an existing wall, after which load is transferred from the building to the piles, where inclined holes are drilled in the wall and where a steel bar is inserted and in-V is fixed in each hole and where connection is made between piles and rods, it is known that a rod (M) is arranged next to each pile (1) in a preferably non-continuous, inclined hole ( 3) in a manner known per se and connected separately to the top (7) of the pad (1) in connection with which the rod (H) is arranged, and by the fact that between the tops (7) of each pair (1 , 1) of piles (I) a hole (5) is drilled, in which a steel bar (8) is inserted and injected firmly and anchored in the top (7) of the piles (1,1), horizontal forces, of which the piles (1) are actuated at the inclined bars (M), are taken up by the bar (8) and the load (Q) fr than the wall (2) can be inserted centrally in the piles (1).
