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 wind, water, and electricity systems and the floor plan of the building, and set information such as the material and size 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 position of each air duct in the air duct pipeline, and determine the elevation and direction of the air duct;

[0035] Step 3. Based on the deepened air duct model, design its supports and hangers, and perform force calculations. According to the force calculation results, reasonably arrange the use form and spacing of the air duct hangers, and according to the wind duct after the layout is completed, Generate a cross-sectio...

Embodiment 2

[0042] Example 2, see Figure 8 , Figure 9 , the difference from Example 1 is: the first boom 3 and the second boom 4 are all telescopic booms; An external thread 12 is provided, and a waist hole 14 is also provided on the telescopic sleeve rod 10; a protrusion 15 is provided on the upper end of the telescopic main rod 11, and when the telescopic main rod 11 is inserted into the telescopic sleeve rod 10, the protrusion 15 is placed In the waist hole 14, and protrude the telescopic sleeve rod 10; Before installation, first adjust the height of the first boom and the second boom, the T-shaped self-locking member 9 passes through the connecting hole and the threaded connection hole, so that the cross arm overlaps with the second boom, and then installs; The jacking device 17 lifts the air duct 18 to the preset position; pulls out the T-shaped self-locking member 9, makes the cross arm 5 rotate 270° around the second suspender 4, and inserts the lower end of the first suspender...

Embodiment 3

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

[0044] In the present invention, the height and size of the air duct hanger must be determined before installation, and once determined, cannot be changed during installation and use. 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 fixed-height self-locking air duct hanger for air duct installation, Example 2 uses an adjustable-height self-locking air duct hanger for air duct installation, and Example 3 uses one of the suspenders as an adjustable Adjust the height of the telescopic suspender, and the other suspender is a self-locking air duct hanger composed of a fixed height suspender for air duct installation. During actual construc...

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 in particular 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, and the size of the wind system pipelines is usually large. During the construction process of the underground garage, there is a high requirement for the headroom height, so when installing the air duct, the air duct hanger needs to be designed separately to meet the requirements. Existing air duct hangers are usually composed of two threaded screws and angle steel cross arms, and the length of the threaded screws often has a certain margin, which is convenient for on-site construction and can be adjusted according to the actual situation. If the remaining length ...
