Embodiment Construction

[0008] Embodiment of the present invention: make parts such as connecting steel plate 1, post-anchor building anchor bolt 2, post-reinforced steel beam 3, and carry out the combined construction of post-reinforced steel beam and concrete slab according to the diagram. Firstly, the positions of the post-increased steel beam 3 and the connecting steel plate 1 are determined on the bottom surface of the built concrete slab 4; secondly, the post-anchoring building anchor bolt 2 is anchored into the built concrete slab 4 at the position of the connecting steel plate 1; then , use post-anchoring building anchor bolts 2 to fix the connecting steel plate 1 on the bottom surface of the built concrete slab 4; finally, weld the post-increased steel beam 3 to the connecting steel plate 1.

Abstract

The invention discloses a method for the combination of a post-increasing steel beam and a concrete slab. Firstly, the location of a post-increasing steel beam (3) and a connecting steel plate (1) is determined on the bottom surface of a built concrete slab (4); secondly, a post-anchoring building anchor bolt (2) is anchored in the built concrete slab (4) at the location of the connecting steel plate (1); then the connecting steel plate (1) is fixed on the bottom surface of the built concrete slab (4) by the post-anchoring building anchor bolt (2); finally, the post-increasing steel beam (3) and the connecting steel plate (1) are connected. The invention uses the post-anchoring building anchor bolt for replacing the traditional shearing connecting piece, is used for bearing the vertical shearing force between the superimposing surfaces of the steel beam and the reinforced concrete slab, restricts the relative sliding of the steel beam and the reinforced concrete slab, causes the steel beam and the reinforced concrete slab to be combined into a whole and work reliably, and provides a simple and effective processing method for the technical transformation of the combination structure of the steel and the concrete.
