Description

Technical Field

[0001] The utility model relates to the technical field of wall-penetrating air duct and fire damper construction, in particular to a fire damper installation structure at a deformation joint. Background Art

[0002] Fire dampers are installed on the supply and return air pipes of ventilation and air conditioning systems or mechanical smoke exhaust systems. They are usually open and close when the gas temperature in the pipe reaches a certain temperature during a fire. They can meet the smoke leakage and fire resistance integrity requirements within a certain period of time, and play a role in isolating smoke and preventing fire. During the installation process, the fire damper needs to be connected to the air duct. It is difficult to fix the installation position, especially at the expansion joint. The space is limited, which makes the installation of the fire damper more difficult. At the same time, the installation of the fire damper requires relatively high precision to ensure the fireproof sealing requirements. Therefore, it needs to remain stable during hoisting. This places strict requirements on the level of the lifting equipment and operators, reduces construction efficiency, and increases construction costs. Utility Model Content

[0003] The purpose of the utility model is to provide a fire damper installation structure at a deformation joint, which can not only realize the lifting and installation of the fire damper, but also can perform shock-absorbing lifting of the fire damper, thereby improving construction efficiency, reducing the use of lifting equipment, and reducing construction costs. The structure is simple and compact and has strong practicality.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0010] Preferably, four shock-absorbing hangers are provided, and the four shock-absorbing hangers are used to hang the four corners of the fire damper.

[0011] In the present invention, the provided shock-absorbing hanger can perform shock-absorbing hoisting on the fire damper, thereby improving the stability of the fire damper during subsequent use, and enabling the entire smoke exhaust system to operate stably and reliably. The provided auxiliary support and hanging assembly is cantilevered on the shock-absorbing hanger, and the fire damper can be hoisted by means of the pulley provided thereon, thereby reducing the use of hoisting equipment during installation, and after hoisting, it can be quickly docked and installed with the shock-absorbing hanger, thereby improving installation efficiency; after hoisting, the pulley can be removed and reused, thereby reducing overall costs.
