Problems solved by technology

During the installation process of the fire damper, it needs to be connected with the air duct. It is difficult to fix the fixed position of the fire damper, which makes the installation of the fire damper more difficult. At the same time, the installation of the fire damper requires relatively high accuracy to ensure the fireproof seal. Demand, therefore, just need those skilled in the art to design a kind of installation method of air duct fire damper

Embodiment Construction

[0027] The present invention will be further described below with reference to the accompanying drawings and examples, and the modes of the present invention include but are not limited to the following examples.

[0028] like Figures 1 to 4 shown:

[0029] An installation method for a parallel air duct fire damper, comprising the following steps:

[0030] First: use a combination of PVC pipes and screws to build a combined module positioning tool with the same size as the fire valve; such as Figure 4 Shown: Make a PVC pipe 7 that matches the installation size of the fire damper, pass a screw 8 of suitable size through the PVC pipe 7, and set positioning nuts 9 at both ends of the screw. When aligning with the air duct, put the screw 8 Pass through the flange holes of the air ducts on both sides, and use the positioning nut 9 to lock and position.

[0031] Secondly, determine the positioning elevation of the fire damper installation, and design and manufacture the limit s...

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...
