A device and construction method for reinforcing cast-in-place stand slabs of stadiums

Abstract

The invention discloses a device and a construction method for reinforcing cast-in-place stand panels of venues, comprising a panel assembly and a keel bracket. The buckle-type support system saves turnover materials and ensures the stability, economy and rationality of the stand panel formwork. The use of adjustable H-shaped bracket components reduces the difficulty of formwork support, and the support can be reused. Upper main keel, front upper vertical formwork panel, upper part of seat board, rear vertical formwork panel, steel pipe main keel, front lower main keel, front lower vertical formwork panel, lower part of seat panel and rear main keel and fasten, and the lower part penetrates the wall The bolts run through the front lower main keel, the front lower vertical formwork panel, the lower side rear vertical formwork panel of the seat panel and the rear main keel in sequence and are fastened to reduce the difficulty of reinforcement and improve the construction speed.

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 venues. Background technique [0002] In the construction of the grandstand slabs of large stadiums, the construction of the grandstand slabs includes prefabrication and cast-in-place. Among them, the prefabricated concrete stands are expensive, difficult to hoist and construct, and the integrity is poor. [0003] The cast-in-place stands are characterized by strong integrity and low cost, but the formwork construction of cast-in-place stands is complicated and the cycle is long. This is mainly due to the narrow space below the seat board, the difficulty of reinforcement, the different heights of the seat board, and the cumbersome formwork support. Also, it is difficult to set the hanging part under the standing beam, which makes the construction cumbersome. SUMMARY OF THE INVENT...

AI Technical Summary

Problems solved by technology

[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
