Description

Technical Field

[0001] This utility model relates to the field of building technology, and in particular to a main frame for a prefabricated building module. Background Technology

[0002] Against the backdrop of the rapid development of prefabricated buildings, the main frame of traditional building modules has many drawbacks: First, its components are often large in size, which not only takes up a lot of space and increases transportation costs during transportation, but is also prone to damage due to collisions; Second, in the assembly stage, traditional frames rely heavily on on-site welding or complex connection methods, which not only consumes a lot of manpower and time and has low assembly efficiency, but also makes it difficult to ensure the stability and consistency of the connection, which seriously restricts the construction progress and quality of prefabricated buildings. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a main frame for a prefabricated building module that can not only achieve rapid assembly and disassembly, but also has the advantages of decentralized loading and low cost.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A main frame for a prefabricated building module includes four rectangular columns, connectors at the upper and lower ends of the columns, two first upper crossbeams spaced apart along the width direction and two first lower crossbeams located below the two first upper crossbeams, and two second upper crossbeams spaced apart along the length direction and two second lower crossbeams located below the two second upper crossbeams; the connectors at the lower end of each column are detachably connected to the corresponding first lower crossbeam and second lower crossbeam, and the connectors at the upper end of each column are detachably connected to the corresponding first upper crossbeam and second upper crossbeam.

[0006] Furthermore, the connector includes two insertion slots fixed to the column, and the two insertion slots are respectively inserted into the corresponding ends of the crossbeam.

[0007] Furthermore, each plug slot is provided with multiple first connection holes, and each crossbeam end is provided with a second connection hole corresponding to the first connection hole. Each plug slot is detachably connected to the corresponding crossbeam through the first connection hole, the second connection hole and bolts.

[0008] Furthermore, the two first upper crossbeams, two first lower crossbeams, two second upper crossbeams, two second lower crossbeams, and two insertion slots are all channel steel, with the ends of each crossbeam inserted into the corresponding insertion slots, and the slots of each crossbeam and the insertion slots of the insertion slots all facing inward.

[0009] Furthermore, it also includes multiple upper hanging beams arranged at intervals along the length direction. Each upper hanging beam has a rectangular notch at its lower end in the width direction, and the two rectangular notches are respectively hooked to the lower groove wall of the two first upper crossbeams.

[0010] Furthermore, it also includes multiple lower hanging beams arranged at intervals along the length direction. Each of the lower hanging beams has an outward-facing slot on both ends in the width direction, and the two slots are respectively inserted into the upper groove wall of the two first lower crossbeams.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] First, in terms of assembly, the design adopts a detachable connection between each beam and the column via connectors and bolts, which enables rapid assembly, eliminates on-site welding procedures, simplifies steps, saves manpower and time, and improves efficiency. In addition, the detachable design facilitates later maintenance, disassembly and reassembly, enhances the flexibility and scalability of the frame, and adapts to the needs of building renovation.

[0013] Secondly, in terms of transportation, since each beam is detachable, it can be loaded separately, avoiding the transportation problems caused by the excessive size of traditional integral frames; decentralized transportation reduces space occupation, improves loading efficiency, reduces costs, and at the same time reduces the risk of component collision damage.
