Large-scale venue assembly type combined prefabricated stand

Abstract

The invention discloses a large-scale venue assembly type combined prefabricated stand, and belongs to the technical field of large-scale arena construction. The stand comprises a prefabricated stand,a prefabricated middle aisle platform and a prefabricated platform with an apron, and further comprises a lower supporting structure, wherein the prefabricated stand, the prefabricated middle aisle platform and the prefabricated platform with the apron are sequentially connected to the lower supporting structure from top to bottom, the front end of the prefabricated stand is spliced with the prefabricated middle aisle platform, the rear end of the prefabricated stand is spliced with the prefabricated platform with the apron, an air supply system is arranged in the prefabricated stand, the airsupply system comprises rear seat air supply ports, an air supply system main interface and a built-in air supply main ring pipe, the plurality of rear seat air supply ports are arranged at equal intervals, the rear seat air supply ports, the air supply system main interface and the built-in air supply main ring pipe are connected to form a loop, and back reverse ridge beam and prefabricated lifting points are arranged on the prefabricated middle aisle platform and the prefabricated platform with the apron. Construction period is greatly saved, quality and safety of components can be ensured,and quality of pre-burying work can be guaranteed.

Description

technical field [0001] The invention belongs to the field of large-scale stadium construction, and specifically relates to a construction method for large-scale stadium stands. It adopts a high-efficiency assembled prefabricated stand for factory production. The stand is suitable for stadium stands of various shapes, saving construction period, ensuring quality, and It can combine the concrete structure and the installation and construction of the fresh air pipeline for prefabrication. Background technique [0002] At present, in the construction of concrete grandstands in large venues, two methods are mainly used: on-site pouring and prefabricated clear water grandstand slabs. In the construction process of reinforced concrete grandstands in large venues, it is necessary to carry out step-by-step construction according to the traditional cast-in-place structural process. It is necessary to build a full hall frame for support, support formwork, bind steel bars, install part ...

AI Technical Summary

Problems solved by technology

However, there are also major defects: such as the cumbersome installation of the air outlets of the stands in closed venues, the messy pipeline laying, the lack of waterproof quality of the open-air stands, and the need to add closed sloping plates under the stand boards in functional rooms, etc.
