Description

Technical Field

[0001] The utility model relates to a concrete foundation steel bar forming support structure, belonging to the technical field of concrete foundation construction. Background Art

[0002] At the variable cross-section of the concrete foundation column structure, in order to ensure that the force of the small-sized part of the column above the soil is dispersed to the large-sized part below the soil, a steel mesh (see Chinese Patent Publication No. CN209227581U) needs to be installed at the variable cross-section before pouring.

[0003] When bundling the steel mesh layer, it is necessary to ensure the distance between the first mesh transverse reinforcement and the column reinforcement, and then arrange the remaining mesh transverse reinforcement and mesh longitudinal reinforcement based on the first mesh transverse reinforcement. Therefore, the mesh transverse reinforcement needs to be supported and positioned; the existing method is to manually place the first mesh transverse reinforcement without support and limitation, which is prone to displacement. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a concrete foundation steel bar forming support structure.

[0005] The utility model is achieved through the following technical solutions.

[0006] The utility model provides a concrete foundation steel bar forming support structure, comprising:

[0007] A supporting structure that can support and position the first placed mesh layer transverse reinforcement.

[0008] It includes: a column structure with the large lower part in the soil and column reinforcement on the top of the column structure;

[0009] A steel mesh layer is distributed on the top surface of the column structure; the steel mesh layer includes mesh transverse reinforcement and mesh longitudinal reinforcement;

[0010] The supporting positioning rods A and B are bundled and fixed on the two vertical surfaces of the column reinforcement. The supporting positioning rods A and B intersect in the middle when projected. The bottoms of the supporting positioning rods A and B bundle and fix the first placed mesh layer transverse reinforcement to support and position it.

[0011] The column reinforcement is composed of column vertical reinforcement A and column embracing reinforcement.

[0012] The column reinforcements are distributed at intervals, bundled and fixed on the outside of multiple column vertical reinforcements A to form a column reinforcement as a whole.

[0013] The mesh layer transverse reinforcements are multiple and spaced apart, and the mesh layer longitudinal reinforcements are multiple and spaced apart and are vertically crossed and bound to the mesh layer transverse reinforcements.

[0014] The ends of the steel mesh layer are welded and fixed with upward vertical mesh reinforcements, which are parallel to the vertical reinforcements A of the column.

[0015] The support positioning rod A and the support positioning rod B intersect in the middle when projected.

[0016] The beneficial effect of the present invention is that the bottom of the support positioning rod A and the support positioning rod B bind and fix the first placed mesh layer transverse reinforcement to support and position it, solving the problem that the first mesh layer transverse reinforcement is prone to displacement after being placed without support and limitation.

DETAILED DESCRIPTION

[0020] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the described solution.

[0021] like Figures 1 to 2 shown.

[0022] A concrete foundation steel bar forming support structure of the present application comprises:

[0023] The large portion below is formed into a column structure 2 extending from the soil 1, with column reinforcement 21 at the top. The column reinforcement 21 is composed of column vertical reinforcement A22 and column embracing reinforcement 23. The column embracing reinforcement 23 is distributed and bundled with multiple column vertical reinforcement A22 to form the entire column reinforcement 21.

[0024] A steel mesh layer 3 is distributed on the top surface of the column structure 2; the steel mesh layer 3 includes mesh transverse bars 31 and mesh longitudinal bars 32. The mesh transverse bars 31 are distributed in multiple intervals, and the mesh longitudinal bars 32 are distributed in multiple intervals and are vertically crossed and tied to the mesh transverse bars 31.

[0025] The two vertical surfaces of the column reinforcement 21 are bundled and fixed with supporting positioning rods A41 and supporting positioning rods B42, and the supporting positioning rods A41 and B42 intersect in the middle when projected. The bottoms of the supporting positioning rods A41 and B42 bundle and fix the first placed mesh layer transverse reinforcement 31 to support and position it, solving the problem that the first mesh layer transverse reinforcement is prone to displacement after placement due to lack of support and limitation; during the forming process of the steel mesh layer 3, the supporting positioning rods A41 and B42 continue to support and position the steel mesh layer 3 until they are removed after the concrete is poured.

[0026] The ends of the steel mesh layer 3 are welded and fixed with upward vertical mesh reinforcements 33 , which are parallel to the column vertical reinforcements A22 .
