Description

Ventilation pipe mounting structure based on space is restricted

Technical Field

The utility model relates to the technical field of ventilation pipelines, in particular to a ventilation pipeline installation structure based on space limitation.

Background

In the building structure of a basement garage of a certain project, the whole reinforced concrete of the columns and the floor (without beams) is cast in situ. Because there is no roof beam, when the tuber pipe of fire control smoke discharge (having the function of airing exhaust concurrently) (ten years ago) of installation, for raising garage headroom as far as possible, the installation process is: manufacturing a suspender and a bracket (lengthening the hanging height), installing an air pipe (taking the space between the upper part of the air pipe and the bottom surface of a floor as an installation operation space because of lengthening the suspender), integrally lifting the air pipe after the air pipe system is tested to be qualified, enabling the upper part of the air pipe to be clung to the lower bottom surface of the floor, cutting off redundant suspenders, and installing other public pipelines (such as fire-fighting water pipes, strong and weak current bridges, water supply and drainage pipes and other pipelines) at the lower part of the air pipe.

Today, fire hose aging is urgent to be modified after ten years, but other pipelines do not need to be modified. Old air ducts sandwiched between the floor and the lower pipeline can be destructively removed, but installing new air ducts is very difficult. Because the traditional connection mode (angle steel flange, common plate flange and internal connection) air pipes cannot be installed normally (air pipe flange connection parts are not tightly connected, are not tightly sealed and are not tight in fireproof package and lack of leakage) is not needed according to the operation space.

Therefore, in order to solve the above-mentioned problems, it is necessary to design a space-limited ventilation duct mounting structure based on the shortcomings of the prior art.
