Embodiment Construction

[0015] Next, the applicant will further explain the present invention in detail with reference to the accompanying drawings.

[0016] like Figure 1-4 As shown, a post-anchoring construction method for a combined floor slab and concrete structure includes the following steps: 1) Installing a profiled steel plate 5: using nails 3 to fix the profiled steel plate 5 in a concrete beam, and the composite floor is set on On the top of the concrete beam 2 or on the corbel 6 on the side of the concrete beam 2, the distance between the nail 3 and the edge of the concrete is greater than 40mm; The bending direction of the reinforcement 4 is the same as that of the concrete beam 2, the anchorage length of the shear bending reinforcement 4 is 300mm, and the bending angle is 45°; 3), binding the floor reinforcement; 4), pouring the floor concrete.

[0017] Among them, the above-mentioned chemical planting bar (referred to as planting bar, also called planting bar) is a post-anchor connect...

Abstract

The invention belongs to the field of building structure construction, and particularly relates to a post-anchoring construction method for a composite floor and a concrete structure. The method comprises the following steps that (1) a profiled steel sheet is mounted, wherein the profiled steel sheet is fixed into a concrete beam by drive pins; (2) shear resistance bent up bars are arranged on the top face of the concrete beam through a mounting chemically planted bar technology; (3) floor reinforcing steel bars are bundled; (4) floor concrete is poured. According to the post-anchoring construction method, the advantage of convenient and quick construction of the composite floor is kept, the post-anchoring problem of the composite floor and the concrete structure is also solved, the construction efficiency is high, mounting is convenient, and the construction measurement cost is greatly reduced.

Description

technical field [0001] The invention belongs to the field of building structure construction, and in particular relates to a post-anchoring construction method for a composite floor slab and a concrete structure. technical background [0002] Composite floor slab refers to the composite floor structure formed by the profiled steel plate as the permanent formwork of the concrete floor slab or as the lower stress reinforcement of the floor slab to participate in the force calculation of the floor slab, and work together with concrete. It has been widely used in steel structure buildings. application. [0003] Although the composite floor slab has many advantages, in the reconstruction of the concrete structure and the project of adding floors, the post-anchoring between the composite floor slab and the original concrete structure often becomes a difficult point in the project. There is no mature solution in China. The conventional method is to install embedded parts or angle s...
