[0002] In recent years, with the booming development of the construction industry and increasingly advanced design concepts, more and more buildings are breaking away from the conventional square shape, especially large stadiums, exhibition halls, train stations, airports, and other public places, which often need unique shapes to become regional landmarks. The irregular steel truss structure of the building's roof plays a crucial role in this. However, the development of anything inevitably brings a series of challenges to overcome, and the installation of decorative ceilings or electromechanical equipment on irregular steel truss structures is one of the problems that needs to be solved in the development of irregular buildings.

[0003] Conventional truss ceilings have a small and regular slope. In most projects, equipment or ceiling transition layers may be fixed to the truss structure using clamps during equipment installation.

[0009] Furthermore, in the aforementioned irregular truss ceiling installation conversion device, the conversion support is provided with a vertical mounting plate, and one or more vertically arranged hangers are provided on the vertical mounting plate along its length direction.

[0010] Furthermore, in the aforementioned irregular truss ceiling installation conversion device, the hanger is a rod-shaped structure, and its top end is connected to the installation vertical plate by an angle bracket; or, the hanger is an angle steel structure, which is connected to the installation vertical plate by welding or bolting.

[0025] Method Implementation Examples: See Figure 7 This is a flowchart illustrating the method for installing suspension rods on irregularly shaped truss ceilings according to an embodiment of the present invention. As shown in the figure, the method includes the following steps: Step S1: Based on the chords of the irregular truss, fabricate several pairs of conversion bases that are compatible with the chords.

[0026] Specifically, based on the dimensions of the truss steel tubes, i.e., the dimensions of the chord members, custom-made structures are as follows: Figure 5 and Figure 6 The conversion base 1 shown can be made of steel.

[0027] Step S2: Install two of the two conversion bases in each pair on the two lower chords of the irregular truss respectively. The two pairs of conversion bases are arranged side by side and spaced apart along the length of the lower chords to form an irregular truss ceiling installation conversion device on the irregular truss.

[0028] Specifically, the transfer base 1 is welded to the upper end of the lower chord 31 of the irregular truss 3 at the required spacing. The base flange 112 of the transfer base 1 is arranged along the direction of the lower chord 31 and is perpendicular to the horizontal plane, that is, the base flange 112 is kept along the direction of the chord and the plane of the base flange 112 is perpendicular to the horizontal plane. Figures 1 to 3 As shown.

[0029] Step S3: Install conversion support members between each pair of conversion bases, and install the two ends of the conversion support members on the two conversion bases respectively. The conversion bases have vertical mounting surfaces arranged in the vertical direction.

[0030] Specifically, the conversion support 2 serves as a secondary structure, with both ends welded to the base flange 112 and the long surface of the conversion support 2 perpendicular to the horizontal plane, serving as the installation vertical surface.

[0031] Step S4: Install the hanger on the vertical surface of the conversion base.

[0032] Specifically, depending on the installation requirements, the equipment and the hanger rod are welded or bolted to the vertical surface of the conversion support 2. For the hanger rod structure 401, the angle steel 5 with the nut 6 installed can be installed on the vertical surface of the conversion support 2 first, and then the threaded rod can be threaded through.

[0033] In summary, the method for installing hangers on irregular truss ceilings provided in this embodiment offers an installation platform for the conversion support through the conversion base on the lower chord. The conversion support provides a vertical surface for hanger installation, facilitating the installation of equipment or decorative ceilings. While providing a fixing point for the equipment, it also ensures easy installation of the equipment or ceiling below. Specifically, a secondary structure is erected on the irregular truss, and the installation angle of the square tubes in the secondary structure is adjusted to provide vertical installation conditions for the equipment below. This allows for a smooth connection between the equipment and the ceiling via hangers or angle steel, improving project safety, reducing construction difficulty, saving labor costs, and shortening the construction cycle. This method greatly facilitates decoration and equipment installation projects in irregular steel truss spaces, solving the problem of the difficulty in fixing equipment or ceiling conversion layers to the truss structure using clamps in existing projects.
