Description

Technical Field

[0001] This utility model relates to the field of building technology, and in particular to a prefabricated building module that is easy to hoist. Background Technology

[0002] As a core component, prefabricated building modules need to be prefabricated in the factory and assembled on site. Therefore, the structural stability, ease of hoisting, and transportation efficiency of the modules directly affect the overall construction quality and cost.

[0003] However, existing prefabricated building modules still have the following problems in practical applications:

[0004] First, there is insufficient safety in hoisting: the hoisting points of traditional modules are mostly fixed welded structures, and if the welding quality is poor, the hoisting points are prone to falling off; some hoisting rings are not strong enough to connect with the main body of the module, and they are prone to tilting, shaking, or even causing safety accidents when subjected to eccentric loads during hoisting.

[0005] Secondly, assembly and transportation are inconvenient: the modular frames are mostly connected by welding or complex bolts, making disassembly difficult. As a result, the modules need to be transported as a whole after being prefabricated in the factory, which takes up a lot of space and has high transportation costs. Moreover, on-site assembly requires the assistance of professional tools, which is inefficient. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a prefabricated building module that is easy to hoist, which can not only improve hoisting safety and stability, but also improve assembly and transportation efficiency.

[0007] The objective of this utility model is achieved through the following technical solution:

[0008] A prefabricated building module that is easy to hoist includes four columns arranged in a rectangle. The lower ends of the columns are detachably connected to adjacent first and second lower crossbeams via connectors. The upper ends of the columns are detachably connected to adjacent first and second upper crossbeams via connectors. The columns, first lower crossbeams, second lower crossbeams, first upper crossbeams, and second upper crossbeams form the main frame of the building module. The upper ends of the columns are detachably connected to lifting rings for hoisting the main frame.

[0009] Furthermore, the column is a rectangular steel pipe, and an end cap is fixed to the upper end face of the column. The end cap has a through hole for the lower end of the lifting ring to pass through. A nut coaxially arranged with the through hole is fixed to the lower surface of the end cap, and the lower end of the lifting ring has an external thread that is threaded to the nut.

[0010] Furthermore, the first lower crossbeam, the second lower crossbeam, the first upper crossbeam, the second upper crossbeam, and the connecting member are all channel steel. The connecting member includes two connecting channel steels fixed to the column, and the ends of each crossbeam are inserted into the corresponding connecting channel steels and abut against the column.

[0011] Furthermore, each beam end is detachably connected to the corresponding connecting channel steel via bolts.

[0012] Furthermore, the slots of each crossbeam and the slots of the connecting channel steel all face inward.

[0013] Furthermore, the through hole is coaxially arranged with the column.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] First, it improves the safety and stability of hoisting: the upper end of the column is connected to the lifting ring by the nut of the first end cap, so that the lifting ring can be detached and the connection is firm, avoiding the risk of the welded lifting point falling off; in addition, the lifting ring and the column are set coaxially, which can ensure that the load is evenly transmitted during hoisting, reduce eccentric swaying, and significantly reduce safety hazards during hoisting.

[0016] Secondly, it improves assembly and transportation efficiency: the columns and beams can be detachably connected by connectors, and the ends of the beams are inserted into the connecting channel steel and fixed with bolts, eliminating the need for complex welding processes. Factory prefabrication and on-site assembly are both more convenient; the modules can be disassembled into columns, beams and other components for transportation, reducing transportation volume and lowering transportation costs, which is especially suitable for transportation in narrow spaces.

[0019] Figure 3 This is a three-dimensional schematic diagram of the column and connector of this utility model. Detailed Implementation

[0020] The present invention will be further described in detail below with reference to the embodiments shown in the accompanying drawings.

[0021] like Figures 1 to 3As shown in the figure, the prefabricated building module that is easy to hoist according to the embodiment of this utility model includes four columns 1 arranged in a rectangle. The lower end of the column 1 is detachably connected to an adjacent first lower crossbeam 3 and a second lower crossbeam 4 through a connector 2. The upper end of the column 1 is detachably connected to an adjacent first upper crossbeam 5 and a second upper crossbeam 6 through a connector 2. The column 1, the first lower crossbeam 3, the second lower crossbeam 4, the first upper crossbeam 5 and the second upper crossbeam 6 form the main frame of the building module. The upper end of the column 1 is detachably connected to a lifting ring 7 for hoisting the main frame.

[0022] As described above, column 1 is a rectangular steel pipe. An end cap 11 is fixed to the upper end of column 1. The end cap 11 has a through hole 12 for the lower end of the lifting ring 7 to pass through. A nut 13 coaxially arranged with the through hole 12 is fixed to the lower surface of the end cap 11. The lower end of the lifting ring 7 has an external thread that is threadedly connected to the nut 13.

[0023] As described above, the first lower crossbeam 3, the second lower crossbeam 4, the first upper crossbeam 5, the second upper crossbeam 6, and the connector 2 are all channel steel. The connector 2 includes two connecting channel steels 21 fixed to the column 1. The ends of each crossbeam are inserted into the corresponding connecting channel steels 21 and abut against the column 1.

[0024] As described above, the ends of each beam are detachably connected to the corresponding connecting channel steel 21 by bolts.

[0025] As mentioned above, the slots of each crossbeam and the slots of the connecting channel steel 21 all face inward.

[0026] As described above, the through hole 12 is coaxially arranged with the column 1.

[0027] The operating steps for lifting the main frame are as follows:

[0028] Confirm that the lifting rings 7 at the top of the four columns 1 are tightened with the corresponding nuts 13. Use a torque wrench to check the matching torque between the external thread of the lifting ring 7 and the nut 13 to ensure that there is no stripping or loose tightening. Then connect one end of the four lifting wire ropes of equal length to the four lifting rings 7 through shackles, ensuring that the shackle pins are tightened. Connect the other end to the lifting hook. The main frame can then be lifted.

[0029] The above description is merely a preferred embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Any simple equivalent changes and modifications made in accordance with the scope of the present utility model patent application and the description of the utility model shall still fall within the scope of the present utility model patent.
