Abstract

The invention discloses an installation method for a parallel air duct fire damper. A combined module positioning tool with the same external dimensions as the fire damper is constructed by combining a PVC pipe and a screw rod. When installing the fire damper, the installation is light and easy The combined module positioning tool is used to locate the installation position of the fire damper, and the air pipes at both ends of the fire damper are fixed and limited according to the installation position of the combined module positioning tool, and then the limit support and hanger are set according to the position of the combined module positioning tool Installation, and then remove the positioning tooling of the combined module, hoist the fire damper to the position where the positioning tooling of the combined module is removed, and finally complete the installation by fastening the bolts. It greatly improves the speed of hoisting and positioning of the fire damper, and also greatly guarantees the accuracy of the installation position of the pairing and docking with the air ducts on both sides, improves the accuracy of the installation of the fire damper, and ensures the quality of the installation of the fire damper.

Description

technical field

[0001] The invention relates to the technical field of industrial equipment installation, in particular to an installation method for a parallel type air duct fire damper. Background technique

[0002] The fire damper is installed at the smoke outlet, where the air duct passes through the fire prevention, where the smoke-proof partition is separated, and where the air duct in the smoke exhaust machine room passes through the wall. Safety. During the installation process of the fire damper, it needs to be connected with the air duct. It is difficult to fix the limit of the installation position, which makes the installation of the fire damper more difficult. Therefore, it is necessary for those skilled in the art to design an installation method of the air duct fire damper. SUMMARY OF THE INVENTION

[0003] The technical problem to be solved by the present invention is to provide an installation method for a parallel type air duct fire damper, so as to imp...
