Description

Technical Field

[0001] The utility model relates to the technical field of steel structure load-bearing frames, in particular to a steel structure load-bearing frame which is convenient for on-site installation. Background Art

[0002] A prefabricated cabin substation, also known as a prefabricated cabin modular substation or a box-type substation, is manufactured in a factory and then transported to the substation site for assembly and operation. On-site assembly of a prefabricated cabin substation is a complex but orderly process, encompassing key steps such as foundation construction, box-type transformer installation, and cable termination. Foundation construction includes the construction of the foundation and the installation of the supporting load-bearing frame. Only after the load-bearing frame is completed can subsequent assembly work be carried out on top of it.

[0003] The existing load-bearing frame is usually composed of basic steel sections, that is, the basic steel sections are laid according to the design requirements, and then connected into an overall frame by welding or bolting to play a supporting role. Since this type of load-bearing frame requires a large number of bolts or welding during the assembly process, it will take up a lot of on-site operation time, which will extend the on-site assembly operation cycle, which is contrary to the original design intention of the prefabricated cabin substation for rapid construction. In addition, the on-site operation environment is usually relatively harsh, and the more complicated the operation, the more susceptible it is to impact. Therefore, in response to the above problems, a steel structure load-bearing frame that is easy to install on-site is proposed. Utility Model Content

[0004] The technical problem to be solved by the present invention is to provide a steel structure load-bearing frame which is easy to install on site. The steel structure load-bearing frame consists of only three parts: a longitudinal bottom beam, a cross beam and a cover plate, and the connection between each other is simple and quick. The longitudinal bottom beam is fixedly connected to the foundation by an anchor connector pre-buried in the foundation, and then the cross beam can be clamped and fixed to the longitudinal bottom beam by a clamping connector, and the anti-detachment plug in the clamping connector can prevent the cross beam from separating from the longitudinal bottom beam. In addition, the cover plate is directly covered on the cross beam and clamped with it. When the equipment or prefabricated cabin is installed on the cover plate, the cover plate can hardly be separated from the cross beam under the action of gravity, which solves the technical problems in the prior art that on-site operations of the load-bearing frame usually require welding or a large number of bolt connections to complete, which will take up more on-site operation time, and the cumbersome installation operation will be affected by the harsh on-site working environment and reduce efficiency or increase difficulty.

[0005] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0040] The use principle and use process of this utility model:

[0041] The steel structure load-bearing frame consists of only three parts: a longitudinal bottom beam 1, a cross beam 2 and a cover plate 5, and the connection between them is simple and quick. Among them, the longitudinal bottom beam 1 is fixedly connected to the foundation through an anchor connector 4 pre-buried in the foundation, and then the cross beam 2 can be clamped and fixed to the longitudinal bottom beam 1 through a clamping connector 3, and the anti-detachment plug 32 in the clamping connector 3 can prevent the cross beam 2 from separating from the longitudinal bottom beam 1.
