Description

The invention relates to construction and can be used for unloading, strengthening and repairing concrete and stone load-bearing walls of buildings.

A device is known for reinforcing the stone walls of buildings with ceilings (see RF patent No. 2205926, published June 10, 2003), containing strands located on at least one side of the reconstructed wall with tension mechanisms fixed at their ends in the supporting nodes of the trusses.

A device is known for reinforcing stone structures of a building (see RF patent No. 2196868, published January 20, 2003), including the installation of unloading elements in the form of wooden racks with a spacer device providing a given degree of unloading of the building wall.

A device for reinforcing concrete and stone structures (see RF patent No. 2077641, published on 04/20/1997), including wells, anchoring elements installed in them, connecting anchoring elements and tightening them together with tensioning devices, was adopted as a prototype. Tensioning devices are included in the work by pre-tensioning by tightening them with flare nuts. The device is a tense belt, including horizontal elements in the form of bands with a mechanism that allows you to adjust the force in them.

The disadvantage of the prototype is the inability to strengthen the base and foundation of the building due to their partial unloading, and only local redistribution of forces in the crack zone is possible.

The technical result is the strengthening and unloading of the bearing walls of the building, in particular their basement sections.

The technical result is achieved by the fact that the device for reinforcing the walls of buildings contains stops based on hinged support plates fixed in the ground, the immobility of which is provided by an inclined metal pipe buried in the ground and bored piles.

Compared with the prototype, where additional measures are necessary to absorb the load transmitted to the basement of the wall and foundation, in the proposed solution, the stops are included in the work by pre-tensioning with a threaded clamping device, solve this problem by transferring part of the load perceived by the basement and foundation to injection piles through support plates provided with a hinge.

The invention is illustrated graphically.

Figure 1 shows a diagram of the device with the location of the stops on two sides of the reconstructed wall, figure 2 is a diagram of the device with the location of the stops on one side of the reconstructed wall, figure 3 is a fragment of the facade.

The device for reinforcing the walls of buildings (Figs. 1, 2) consists of two horizontal elements 1 installed in shtabs, made on the reinforced wall from the inner and outer sides, tightened together by threaded ties 2. On both sides of the reinforced wall through the building foundations are arranged bored piles 3 and inclined metal pipes 4, which are partially left in the ground pipes used in the construction of bored piles 3. Stops 5 are installed on at least one side of the reconstructed wall, which fastened to the horizontal element 1 in the groove and rest on the support plates 6, provided with hinges and anchored into the ground. Stops 5 are included in the work by pre-tensioning with a threaded clamping device 7. Stops 5 are made of pipes, the diameter of which is determined by calculation, depending on the required degree of reinforcement of the structure. Threaded ties 2 connecting the horizontal elements are installed in increments determined by calculation (figure 3).

Claims (1)
