Further, in order to make the public have a better understanding of the present invention, some specific details are described in detail in the following detailed description of the present invention. Those skilled in the art can fully understand the present invention without the description of these details. Example

[0022] A prefabricated chemical pipe gallery frame includes a top welding assembly frame 1, which is a customized welding frame for chemical pipelines to be erected thereon. Since each plant area has different requirements for the size and quantity of chemical pipelines, welding customization is required. At the same time, in order to adapt to the subsequent transformation of the plant area, other parts include a support frame 2, a vertical rod 3, a horizontal rod 4, and a pulling rod 5. The support frame 2 is provided with multiple groups, which include support rods 201 that are mutually scissor-hinged, one end of the two support rods 201 can be extended outward, and the other ends of the two support rods 201 are hinged with a base block 202 placed on the ground. The support rod 201 is hinged with a support rod buckle 203 at the extension section, and a pin hole 204 is penetrated on the support rod buckle 203. Through the two The hinged rotation between the support rods 201 can make the height of the support rod buckle 203 at the top end be adjusted, and the vertical rod 3 is placed on the two support rod buckles 203 of the same group of support rods 201. At the same time, in order to prevent the vertical rod 3 from slipping, a fixing hole is opened on the vertical rod 3, and a corresponding pin hole 204 is opened at the position. A positioning pin 301 is concentrically penetrated through the pin hole 204 and the fixing hole to avoid the separation of the vertical rod 3, and a plurality of rod sleeves 401 are fixed on the cross rod 4. The rod sleeves 401 are installed corresponding to the plurality of vertical rods 3. At the same time, the spacing between the rod sleeves 401 is adjustable to adapt to adjacent support frames 2 with different spacings. In order to prevent the cross rod 4 from slipping off the vertical rod 3, the pulling rod 5 is used to pull the two cross rods 4, and the length is adjustable.

[0023] Specifically, when in use, first make the support frame 2 Figure 1The spacing between two adjacent support frames 2 is arranged according to the on-site construction environment. Then, after the two support rods 201 of the support frame 2 are driven to rotate and adjust to a suitable height, concrete square columns are poured around the base block 202 to prevent it from moving, so that it cannot move, thereby preventing the two support rods 201 from rotating relative to each other. At the same time, the vertical rod 3 is erected on the support rod buckle 203, and the positioning pin 301 is passed through the fixing hole and the pin hole 204, so that the vertical rod 3 cannot be separated from the support rod buckle 203 (the fixing hole is temporarily opened for the purpose of The rod sleeve 401 is then correspondingly sleeved on the vertical rod 3 to fix the horizontal rod 4. In order to prevent the horizontal rod 4 from separating from the vertical rod 3, it is pulled by the pulling rod 5. Finally, the top welding assembly 1 is welded or screwed to the rod sleeve 401 to achieve assembled installation. In this solution, except for the top welding assembly that cannot be reused, other assemblies can be adjusted to adapt to subsequent factory expansion and modification, thereby achieving the purpose of secondary utilization, saving construction costs, and reducing the problem of long welding period.
