Heat insulation hanger applied to air duct belt hanger and method for installing air duct

Abstract

The invention discloses a heat insulation lifting head applied to a band type lifting bracket of an air pipe and a method for mounting the air pipe and solves the problems that an existing heat insulation lifting head has a complicated structure and is inconvenient to assemble and high in cost. The heat insulation lifting head comprises an adjusting frame, a heat insulation saddle, a lifting band, a lifting plate and a lock shaft, wherein a first connecting hole which is used for buckling the lifting plate and the adjusting frame together is formed inside the lifting plate; a second connecting hole is further formed in the position, below the first connecting hole, in the lifting plate; one end of the lifting band is connected with the air pipe, and the other end of the lifting band penetrates through the second connecting hole, surrounds the outer edge of the lock shaft for a circle by being attached to the outer edge of the lock shaft, and then reversely penetrates through the second connecting hole; the heat insulation saddle is arranged in the first connecting hole and completely separates the adjusting frame from the lifting plate; the length of the lock shaft is greater than the length of the second connecting hole, so that the hanging band winds the lock shaft, penetrates through the second connecting hole and then is fixedly arranged on the lifting hanging plate. The heat insulation head has the advantages of simple structure, reasonable design, convenience in assembly and low cost. The defects in the prior art are well overcome in an ingenious mode, so that the heat insulation lifting head is suitable for being popularized and applied.

Description

technical field [0001] The invention relates to a heat-insulating hanger, in particular to a heat-insulated hanger applied to an air duct belt hanger and a method for installing the air duct. Background technique [0002] At present, air-conditioning iron air ducts, especially air-conditioning duct hangers, are installed with angle steel or channel steel cross arms and cold bridge wood structures. This installation method has the following defects: [0003] (1) This method uses wood as a cold insulation measure. However, in today's increasingly stringent fire protection requirements, this cold insulation measure has been difficult to meet the demanding fire protection requirements. If flame-retardant and heat-insulating materials are used, the cost is extremely high; and the cold bridge wood needs to be cut on site according to the width of the air duct. The saw dust that is cut will seriously pollute the environment and is extremely poor in environmental protection. [000...

AI Technical Summary

Problems solved by technology

[0003] (1) This method uses wood as a cold insulation measure. However, in today's increasingly stringent fire protection requirements, this cold insulation measure has been difficult to meet the demanding fire protection requirements

If flame-retardant and heat-insulating materials are used, the cost is extremely high; and the cold bridge wood needs to be cut on site according to the width of the air duct, and the saw dust that is cut will seriously pollute the environment, and the environmental protection is extremely poor

[0004] (2) Due to the thickness of the cold bridge wood, the height of the space occupied by the air duct is correspondingly increased, so that it is often difficult to arrange the integrated pipelines in the building to meet the minimum space required by the human body

[0005] (3) When installing air ducts, because the number and specifications of the cross arms are difficult to accurately determine, it is generally necessary to make and process air ducts on site, such as material cutting, drilling, rust removal, anti-corrosion, etc. In this way, not only processing Long time, high labor cost, occupying a lot of temporary space, and there are many safety hazards

In this way, the processing difficulty of the heat insulation saddle is increased

[0009] (2) The structure is not simple enough: In order to effectively insulate the heat, this kind of heat insulation hanging head is equipped with a heat insulation matching component with a relatively complicated structure and an insulation layer. After the heat insulation hanging head is assembled, its overall structure more complex

[0010] (3) There are safety risks: In the case of some dimensional deviation of the heat insulation block, accidental damage of the heat insulation block, improper installation of the clip, accidental lifting of the air duct due to external force during use, etc., the two heat insulation blocks clamp The live sling may fall off, causing an accident
