A construction method of sandwich composite glass fiber reinforced plastic static pressure box in auditorium

Abstract

The invention provides a sandwich composite glass fiber reinforced plastic plenum chamber for an auditorium and a construction method of the sandwich composite glass fiber reinforced plastic plenum chamber for the auditorium. The sandwich composite glass fiber reinforced plastic plenum chamber for the auditorium is arranged under a seat area of the auditorium and comprises a floor slab and a box body below the floor slab. The floor slab is used as a box body top cover and connected with the box body. An air outlet is formed under each seat. The box body comprises a bottom face plate and side face plates. The bottom face plate is composed of bottom face plate strips and a horizontal keel frame. Each bottom face plate strip is formed by connecting multiple sandwich glass fiber reinforced plastic composite boards in an end-to-end mode one by one in a flanged mode. The horizontal keel frame is formed by fixing transverse main keels and longitudinal auxiliary keels in a crossed mode. Each bottom face plate strip is embedded between every two adjacent rows of transverse main keels. The transverse main keels are connected with a floor slab embedded piece through a suspender. The edges of the side face plates and the edge of the bottom face plate are connected through flanges. The tops of the side face plates are connected with the floor slab. The sandwich composite glass fiber reinforced plastic plenum chamber for the auditorium is high in overall rigidity, high in bearing capacity, high in adaptability, resistant to fire and corrosion, and capable of isolating sound and absorbing shock. In addition, the technology is simple, the assembly speed is high, later-period overhauling is convenient, the material cost and the labor cost are greatly reduced, and the construction period is shortened.

Description

technical field [0001] The invention relates to a static plenum box for ventilation, in particular to a construction method for a sandwich composite glass-steel plenum box suitable for audience halls of buildings such as movie theaters and conference halls. Background technique [0002] In recent years, my country's economy has continued to flourish, the income level of the whole society has continued to increase, and the cultural life needs of the people have gradually increased. This has promoted the development of my country's cultural undertakings, and many theater-like buildings have been newly built across the country. At present, in order to improve the quality of air supply in theaters and conference halls, air inlets are installed under each seat, holes are reserved on the concrete floor where the seats are fixed to install air supply pipes, and a double-layer structure floor is installed below the floor. Static plenum or hexahedral plenum made of galvanized iron. ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a construction method for a sandwich composite FRP static plenum in an auditorium, which solves the problem that the double-layer floor plenum occupies a large space in the prior art, the structure is heavy, condensed water is easy to appear under the floor, and the construction difficulty is high. And the technical problem of long construction period; at the same time, it overcomes the need for on-site splicing in the installation process of the galvanized iron hexahedron static pressure box in the prior art, a large number of splicing seams, a large workload, and on-site welding is easy to cause fire, fire prevention, anti-corrosion, sound insulation and shock absorption Poor performance, stainless steel plate needs special insulation layer, steel plate is prone to resonance under the action of wind pressure, and because personnel cannot enter the static pressure box, it is time-consuming and laborious to clean up garbage or maintain the structure in the later technical problems
