Description

I

The invention relates to the construction and can be used to strengthen the strip foundations of buildings and structures.

Known base reinforced concrete block rectangular

This foundation block is characterized by high material consumption and, moreover, when using such blocks, to reinforce the foundation, they cannot be used together with the base.

Closest to the present invention is a foundation reinforced concrete block, made with a through horizontal cavity 2.

Being economical in terms of the consumption of concrete, the known foundation reinforced concrete block, when used to strengthen the strip foundation, also requires considerable labor to be included in the joint work with the foundation.

The purpose of the invention is to reduce labor costs for the incorporation of a foundation reinforced concrete block into operation when reinforcing strip foundations.

This goal is achieved by the fact that a foundation reinforced concrete block, made with a through horizontal cavity, is made with a vertical recess communicating with a horizontal cavity and provided with inserts, one of which is installed in a vertical notch with the possibility of vertical movement, and the other two are placed in a horizontal cavity along its ends are interconnected by a stitch, and at least one of the inserts placed in the horizontal cavity is mounted with the possibility of horizontal movement, and the vertical notch and the horizontal cavity are filled with plastic hardening material.

Claims (2)

Working reinforcement can be used as a tie. 3 In FIG. 1 shows a foundation reinforced concrete block, cross section; in fig. 2 - cut LA. in fig. 3 reinforced concrete block, placed under the base of the reinforced foundation, cross section; in fig. - section bb in fig. 3. In reinforced concrete block 1, which has a through horizontal cavity 2, there is a vertical notch 3 in which a movable liner is placed. At the ends of the through horizontal cavity 2 there are placed liners 5, which in turn have through holes 6 according to the number of additional reinforcing bars longitudinal reinforcement of the block used as a tie. Moreover, at least one of the liners 5 is made movable. To reinforce the strip foundations ™ 7, working fittings 8 with threads at the ends are pulled through holes 6 in the liners. After performing the earthworks and installing the block in a trench next to the foundation, the cavity 2 is filled with plastic hardening material 9, after which the liner is installed and the block is placed under the bottom of the reinforced foundation 7. The material 10) is compressed by tightening the nuts 10 pressure on the lower surface of the liner 4, presses it against the lower surface of the foundation 7. For reliable contact of the liner k with the sole of the reinforced foundation on the upper end of the liner 4 can be pre-laid following A mortar is made of cement mortar, and for uniform pressure transfer from unit 1 to the ground of the base sand preparation can be poured. After the material 9 has hardened, the nuts 10 can be removed for further use, and the reinforcement 8 will act as a longitudinal pre-stressed working reinforcement of the block, which will increase the strength of the block. Block 1, liners k and 5 can be made of reinforced concrete, filled with CAVITY 2 can be made of plastic concrete mixture. The diameter of the working reinforcement 8 is assigned in each particular case depending on the magnitude of the design resistance of the soil, which allows economical use of metal to reinforce the block, and install the blocks close to each other or with gaps without changing their dimensions. In this case, the blocks can be used as blocks-pillows reinforced foundation. The use of the proposed base reinforced concrete block due to the simplicity of operations for the inclusion of the block in the work reduces labor costs while strengthening both monolithic and precast strip foundations. Claim 1. Fundamental reinforced concrete block, made with a through horizontal cavity, characterized in that, in order to reduce labor costs for the inclusion of the block in the work when strengthening the strip foundation, it is made with a vertical notch communicating with the horizontal cavity, and is equipped with inserts installed in a vertical recess with the possibility of vertical movement, and the other two are placed in a horizontal cavity at its ends and are interconnected by a tie, and at least one of The liners placed in the horizontal cavity are mounted with the possibility of horizontal movement, and the vertical recess and the horizontal cavity are filled with plastic hardening material. 2. The unit according to claim 1, characterized in that the working reinforcement is used as the tie. Sources of information taken into account in the examination 1. Designer's handbook.
