Problems solved by technology

If the remaining length of the threaded screw is too long, not only the appearance is not beautiful, but also it is easy to cause waste of materials
Moreover, the height of this kind of hanger is adjusted by the construction personnel themselves. There are errors in this adjustment, which will affect the overall force of the hanger and will adversely affect the subsequent installation of the air duct.
At the same time, the existing air duct hanger still has the following problems: the cross arm can only be installed when the air duct is installed, the process is cumbersome, multiple people are required to work at the same time, and there is a problem of low efficiency

Embodiment 1

[0032] Example 1, see Figure 1-Figure 7 , a method for installing an air duct using a self-locking air duct hanger, comprising the following steps:

[0033] Step 1: Establish a three-dimensional model of the building according to the building's wind, water, electricity system and floor plan, and set the material, size and other information of the air duct in the three-dimensional model;

[0034] Step 2: Through the in-depth design of the three-dimensional model, the mechanical and electrical professional technicians reasonably arrange the positions of each air duct in the air duct pipeline, and determine the elevation and direction of the air duct pipeline;

[0035] Step 3. According to the deepened air duct model, carry out support and hanger design, and perform force calculation. According to the force calculation results, reasonably arrange the use form and spacing of the air duct hangers, and according to the wind after the layout is completed. Pipe pipe position generat...

Embodiment 2

[0042] Example 2, see Figure 8 , Figure 9 , the difference from Embodiment 1 is that the first boom 3 and the second boom 4 are both telescopic booms; There is an external thread 12, and a waist circle hole 14 is also opened on the telescopic sleeve rod 10; the upper end of the telescopic main rod 11 is provided with a protrusion 15. When the telescopic main rod 11 is inserted into the telescopic sleeve rod 10, the protrusion 15 is placed on the telescopic sleeve rod 10. Inside the waist circular hole 14, the telescopic sleeve rod 10 protrudes; the adjusting nut 13 is arranged on the telescopic sleeve rod 11, and is placed under the protrusion 15. Before installation, adjust the height of the first boom and the second boom, and the T-shaped self-locking member 9 passes through the connection hole and the threaded connection hole, so that the cross arm and the second boom are overlapped, and then the installation is carried out; The jacking device 17 lifts the air duct 18 t...

Embodiment 3

[0043] Embodiment 3 is different from Embodiment 2 in that one of the booms is a height-adjustable telescopic boom, and the other boom is a fixed-height boom.

[0044] In the present invention, the height and size of the air duct hanger must be determined before installation, and cannot be changed during installation and use once determined. The self-locking function of the air duct hanger is realized through the T-shaped self-locking member 9 , the first through hole 6 , the insertion hole 7 and the threaded connection hole 8 .

[0045] Example 1 uses a self-locking air duct hanger with a fixed height for air duct installation, Example 2 uses a self-locking air duct hanger with adjustable height for air duct installation, and Example 3 uses one of the hanging rods to be adjustable. The height-adjustable telescopic boom, and the other boom is a self-locking air duct hanger composed of a fixed-height boom for air duct installation. In actual construction, if the floor bottom sur...

Abstract

The invention discloses a method for mounting a wind pipe by a self-locking wind pipe lifting frame. The method comprises the following steps: firstly, a three-dimensional model of a building is built to determine a position and an elevation of the wind pipe; a new wind pipe lifting frame is designed according to the position and the elevation of the wind pipe; and the wind pipe is mounted by the wind pipe lifting frame. The method enables installation of the wind pipe to become simple, and can guarantee the wind pipe to position in the same one horizontal height.

Description

technical field [0001] The invention belongs to the technical field of building construction, and particularly relates to a method for installing an air duct by using a self-locking air duct hanger. Background technique [0002] At present, the system functions of large-scale projects are becoming more and more perfect, and the types and quantities of mechanical and electrical equipment pipelines are increasing, among which the size of the wind system pipelines is usually larger. During the construction of the underground garage, the clearance height is required to be high, so when installing the air duct, it is necessary to design the air duct hanger separately to meet the requirements. The existing air duct hanger is usually composed of two through wire screws and angle steel cross arms, and the length of the through wire screws is often left with a certain margin, which is convenient for on-site construction and height adjustment according to the actual situation. If the...
