Problems solved by technology

[0004] However, the existing exhaust duct has the following two problems in the installation process: 1. The installation efficiency of the exhaust duct is low; The technician needs to use the support rods to push the plank against the floor to close the second opening; the technician needs to remove the support rods after the technician has added filler to the gap between the outer wall of the exhaust duct and the wall of the mounting hole , to achieve the separation of plank and floor
2. The smoke isolation effect of the exhaust duct is not good; the exhaust duct is welded by multiple pipes and connected together, and the welding between adjacent pipes is prone to smoke leakage

Abstract

The invention relates to an installation method for an exhaust duct of a building, which solves the problems of low installation efficiency of the exhaust duct and poor smoke isolation effect. An installation method for an exhaust duct of a building, the installation method of the exhaust duct comprises the following steps: S01) opening a mounting hole on a floor slab of a building; S02) installing a fixed plate of one group of exhaust units in it The lower end face of a floor plate, and the installation hole on the floor plate is communicated with the space below it through the through hole; S03) The metal pipe of the exhaust unit described in step S02 is placed on the support, and when the metal pipe is placed on the support When on the object, the lower end of the metal pipe is connected with the support to close the gap between the two, and the upper end of the metal pipe penetrates the through hole in step S02 and is inserted into the installation hole described in step S02; S04) replace in step S02 The lower end of the connecting pipe of the exhaust unit is inserted into the installation hole, so as to realize the direct connection or indirect connection between the clamping part on the connecting pipe and the upper end of the metal pipe.

Description

technical field [0001] The invention relates to a method for installing an exhaust duct of a building. Background technique [0002] Residential buildings usually include multiple floors and exhaust ducts. Different floors are separated by floors, and each floor is divided into several residences by walls. The exhaust ducts run through the floors to discharge the smoke in the residences to the outside of the residential buildings. [0003] The existing floor slab has installation holes. When the exhaust duct passes through the installation hole, the technician will add filler (the filler can be cement or other viscous liquid) to the outer wall of the exhaust duct and the installation hole. In the gap between the walls to realize the integration of the exhaust duct and the floor. The gap between the outer wall of the exhaust channel and the wall of the installation hole has a first opening and a second opening corresponding to the first opening, wherein the first opening is ...
