Construction device and method for bearing platform and ground beam structure

Abstract

The invention discloses a construction device and method for a bearing platform and ground beam structure. The device comprises bearing platform side formworks (1) and ground beam side formworks (2) which are of a reinforced concrete structure. A convex strip (3) on each side of each bearing platform side formwork (1) abuts against a convex strip (3) on the adjacent side of the adjacent bearing platform side formwork (1) in a mutually meshing mode. The lower ends of every two parallel ground beam side formworks (2) are supported by concrete supporting blocks. Positioning steel bars (6) bent outwards are fixed to the top edge of each ground beam side formwork (2). Telescopic supporting rods (7) are arranged between every two parallel ground beam side formworks (2). The key of the method lies in that the bearing platform side formworks (1) and the ground beam side formworks (2) which are of the reinforced concrete structure are prefabricated and then are hoisted and strengthened on site. By means of the device and method, the construction intensity of workers can be relieved, the construction process is fast and convenient, and the construction period can be shortened.

Description

technical field [0001] The invention relates to the field of civil engineering construction, in particular to a construction device and a construction method for a bearing platform and a ground beam structure at the bottom of a foundation pit. Background technique [0002] The bottom of the foundation pit mostly adopts caps and ground beam structures. Specifically, it is an integral structure in which the basement floor (referred to as the bottom plate), ground beams and caps are poured in one piece. Among them, each cap is located above the pile foundation, and the ground beam is located between the two caps to connect the two caps, and the bottom plate is located above the cap and the ground beam, and the top level of the bottom plate is the same as the top of the cap and the ground beam. The elevation is even. [0003] Since the bottom slab covers and closes the top of the cap and the ground beam, and the concrete of the bottom slab, cap, and ground beam is poured integr...

AI Technical Summary

Problems solved by technology

[0005] The biggest defect of the construction method of the cap and ground beam structure in the prior art is that the process of laying the brickwork side formwork is time-consuming and laborious, which increases the labor intensity of the workers, and the mortar of the brickwork formwork needs a certain curing time to dry. Hard to meet the strength requirements of the back soil on the side, so the construction period was delayed
