Device for reinforcing cast-in-place grandstand plate in venue and construction method of device

Abstract

The invention discloses a device for reinforcing a cast-in-situ grandstand plate in a venue and a construction method of the device. The device comprises a panel assembly and a keel support, the keel support is installed on the lower side of the panel assembly, a supporting bottom frame is arranged on the lower side of the keel support, a disc buckle type supporting system is used, turnover materials are saved, and it is guaranteed that a grandstand plate formwork is stable, economical and reasonable; an adjustable H-shaped support assembly is used, the formwork erecting difficulty is reduced, the support can be reused, and an upper wall penetrating bolt sequentially penetrates through a front upper main keel, a front upper formwork erecting panel, the upper part of a seat plate, a rear formwork erecting panel, a steel pipe main keel, a front lower main keel, a front lower formwork erecting panel, the lower part of the seat plate and a rear main keel and is fastened; and a lower wall penetrating bolt sequentially penetrates through the front lower main keel, the front lower formwork erecting panel, the lower side rear formwork erecting panel of the seat plate and the rear main keel and is fastened, the reinforcing difficulty is reduced, and the construction speed is accelerated.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a device and a construction method for reinforcing cast-in-place grandstand panels of stadiums. Background technique [0002] In the construction of grandstand slabs of large stadiums, there are two types of construction of spectator slabs: prefabricated and cast-in-place. Among them, the cost of prefabricated concrete spectator stands is high, the hoisting construction is difficult, and the integrity is poor. [0003] The cast-in-place stands are characterized by strong integrity and low cost, but the construction of the formwork of the cast-in-place stands is complicated and the cycle is long. This is mainly due to the small space under the seat boards, the difficulty of reinforcement, the height difference of the seat boards, and the cumbersome support of the formwork. And it is difficult to set up the hanging part of the vertical beam on the back of the seat, re...

[0002] In the construction of grandstand slabs of large stadiums, there are two types of construction of spectator slabs: prefabricated and cast-in-place. Among them, the cost of prefabricated concrete stands is high, the hoisting construction is difficult, and the integrity is poor.

[0003] The cast-in-place stand is characterized by strong integrity and low cost, but the construction of the formwork of the cast-in-place stand is complicated and the cycle is long. This is mainly due to the small space under the seat board, difficult reinforcement, different height differences of the seat board, and cumbersome formwork support. And it is difficult to set up the hanging part of the sitting back vertical beam, resulting in cumbersome construction
