Reinforcing and supporting device for civil air shaft lining common-plate flange air pipes and construction method of reinforcing and supporting device

Abstract

The invention discloses a reinforcing and supporting device for civil air shaft lining common-plate flange air pipes and a construction method of the reinforcing and supporting device. The reinforcingand supporting device comprises angle brace reinforcing gaskets, reinforcing bolts, common-plate flange clamps, supporting sleeves and L-shaped air pipe supports, wherein four angle brace parts of aflange and the angle brace reinforcing gaskets are fixed through the reinforcing bolts in angle brace screw holes; the common-plate flange clamps are clamped on the peripheries of flanges of every twoadjacent common-plate flange air pipes to be fixed; the L-shaped air pipe supports are arranged below the two side edges, intersecting with a primary concrete wall, of the flanges; the reinforcing bolts penetrate through the supporting sleeves and long-strip-shaped bolt reserved grooves in the L-shaped air pipe supports and are fixed to the bottoms of the L-shaped air pipe supports through lowernuts; expansion screw holes are reserved in the longitudinal parts of the L-shaped air pipe supports; and expansion bolts are reserved in the primary concrete wall and penetrate through the reserved screw holes, and the L-shaped air pipe supports are fixed to the primary concrete wall through expansion nuts. According to the reinforcing and supporting device, the construction difficulty is lowered, the project quality is improved, and smooth completion is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to a reinforcement support device for a common-plate flange air duct lining a civil air shaft and a construction method thereof. Background technique [0002] In current residential projects, the application of pressurized air supply and smoke prevention systems is relatively common. In previous projects, the pressurized air supply and anti-pressure system consisted of a pressurized air supply fan, a civil shaft and a pressurized air supply outlet at the end. In the "Technical Standard for Building Smoke Prevention and Smoke Exhaust System" that came into effect on August 1, 2018, 3.3. Article 7 clearly stipulates that the mechanical pressurized air supply system should use pipelines, and civil air ducts should not be used, which greatly increases the construction difficulty of the pressurized air supply system. Most of the methods in the prior art are to line the ...

AI Technical Summary

Problems solved by technology

[0003] The invention provides a reinforcement support device and a construction method for a civil air shaft lined with a common-plate flange air duct and a construction method thereof, which solves the problem that in the prior art, the civil air shaft lining galvanized sheet air ducts are connected by angle steel flanges and there are many flange holes , the construction space is small, which makes it impossible for workers to fasten the bolts at the flange, and the operation steps are cumbersome, which increases the difficulty of fixing the air duct, reduces the difficulty of construction, improves the quality of the project, and ensures smooth completion
