Description

Reinforced prefabricated concrete support blocks for multifunctional shear walls

technical field

The utility model relates to the technical field of building construction, in particular to a multifunctional shear wall reinforced prefabricated concrete support block.

Background technique

In the field of engineering construction, during the construction of the shear wall structure, it is very critical to strictly control the design thickness of the shear wall, the thickness of the protective layer of the steel bar, and the distance between the two rows of steel bars in the shear wall, which will affect the safety and aesthetics of the structure. , Therefore, there must be a construction technique to effectively control the thickness of the protective layer of the shear wall reinforcement, the spacing between the two rows of reinforcement, and the thickness of the shear wall. Existing construction generally adopts protective layer pads with only grooves for fixing horizontal steel bars to control the thickness of the shear wall and the thickness of the protective layer of shear wall reinforcement. , falling, etc., or use double-control support but need to take other measures to control the thickness of the shear wall, which affects the construction quality. For this reason, the existing reinforced concrete support blocks for the shear wall need to be improved.

Utility model content

The technical problem to be solved by the utility model is to provide a multifunctional shear wall reinforced prefabricated concrete support block, which can fix the concrete support block at a designated position, and can effectively avoid the deviation and falling of the support block. , Improve the construction quality.

The technical scheme adopted by the utility model to solve the above-mentioned technical problems is: a multifunctional shear wall reinforced prefabricated concrete support block, including a concrete support block matrix, which is prefabricated by fine stone concrete, and two A groove for fixing the horizontal reinforcement, and two grooves for fixing the vertical reinforcement are provided on the side of the concrete support block.

The concrete support block matrix has a cross-sectional size of 40mm×30mm, and the cross-sectional size can be adjusted according to specific construction requirements, and its length is equal to the thickness of the shear wall, which ensures the stability of the concrete support block resting on the horizontal steel bar. It also ensures the thickness of the shear wall.

The concrete support block matrix is arranged at the intersection of the horizontal steel bar and the vertical steel bar, effectively controlling the position of the steel bar, and at the same time fixing the position of the concrete support block, which solves the problems of the concrete support block shifting and falling.

detailed description

Below in conjunction with embodiment and accompanying drawing, the technical solution of the utility model is described in further detail.

Example

As shown in Figure 1, the multifunctional shear wall reinforced prefabricated concrete support block 1 has a matrix of a cuboid fine stone concrete piece, including two fixed horizontal reinforcement grooves 2 and two fixed vertical reinforcement grooves 3 .

The depth of groove 2 and groove 3 is 15mm, and the depth can be adjusted according to the specific construction requirements. The width matches the diameter of the steel bar.

As shown in Figures 2 to 3, the installation method of the utility model is: first determine the thickness B of the shear wall, the thickness C of the protective layer of the steel bar in the shear wall, and the diameter d of the steel bar, and then according to the thickness of the shear wall and the thickness of the protective layer on site Prefabricate concrete support blocks of the corresponding size, and the strength of the concrete support blocks should not be lower than the concrete strength of the shear wall; this scheme adopts the plum blossom-shaped installation scheme. When installing, first fix the horizontal reinforcement groove 2 of the concrete support block 1 on the The shear wall is horizontal to the reinforcement 4, and then the protective layer pad 1 is pushed to the left (or right), so that the vertical reinforcement 5 is fixed in the vertical reinforcement groove 3 of the protective layer pad 1, and the completion is complete Install.
