2. Description of the Related Art Conventionally, for example, Japanese Utility Model Laid-Open Publication No.
No. 056, Japanese Utility Model Publication No. 2-47389, etc., it is possible to assemble and install at a work site, and disassemble it into a small volume to make it convenient for transportation and storage. An assembly type damper used for an air conditioning duct or the like is already known.

[0003]

[Problems to be Solved by the Invention] However, air-conditioning ducts and the like are generally often suspended from air-conditioning equipment in high-rise buildings and condominiums. No means are provided to support the hanger. Therefore, conventionally, the assembling type damper is merely interposed in the middle of the bridge duct. Therefore, the damper blade,
When using a damper blade opening adjuster or damper switch, and a plurality of damper blades, an interlocking mechanism is attached to the damper blades, so that they may be weighted and assembled in the middle of a suspended duct. If only the built-in damper is installed, the set position of the assembled duct is displaced by the weight of the assembled duct and is not stable. Therefore, for example, it becomes difficult to perform the opening adjustment operation of the damper blade by the opening adjustment handle from the predetermined ceiling or other narrow adjustment opening, and the duct only supports the assembled damper. In addition, there has been a problem that cracks, gaps, and the like are generated in a connection portion between the duct and the damper casing at an early stage, and safety and durability are also lacking.

[0004] The assembled damper of the present invention solves the above-mentioned problems, and always stably holds an assembled damper installed in the middle of an air-conditioning duct or the like to improve usability.
An object of the present invention is to provide an assembling type damper with improved safety and durability.

[0005]

SUMMARY OF THE INVENTION To solve the above-mentioned problems, the present invention provides an assembly type damper comprising upper and lower casing veneers 1, 2 having flange portions 5 on both sides and connecting attachment pieces 6 on both ends. And left and right casing veneers 3, 4 having flange portions 7 on both sides and provided with coupling receiving pieces 8 at both ends, and connecting attachment pieces 6 of both casing veneers 1, 2, 3, 4. The connection receiving piece 8 is superimposed, and a reinforcement L is provided at a corner abutting portion between the projecting piece 5a of the flange portion 5 of the upper and lower casing veneers 1 and 2 and the flange portion 7 of the left and right casing veneers 3 and 4. In the assembly type damper in which the damper casing A is assembled by integrally fixing and connecting these with fixing metal members 9 such as studs via the mold corner plate 10, the connecting attachment piece 6 and the connection receiving piece 8 are used. Suspension of the hanger 16 when the duct is suspended at the corner connection And summarized in that with a lower support means 17.

[0006]

The assembly type damper of the present invention having the above construction has a corner in which the connecting attachment pieces 6 of the upper and lower casing veneers 1 and 2 and the connecting receiving pieces 8 of the left and right casing veneers 3 and 4 are fixed by polymerization. Since the hanging support means 17 is provided at the connecting portion,
If the hanging member 16 is supported by the hanging supporting means 17, the assembling damper is firmly suspended and held by the hanging member 16. As a result, the assembled damper is stably suspended and installed, and its operability, safety and durability are improved.
