The fifth support plate 11 and the canopy beam 4 are connected and fastened through bolt connection holes and a second limiting piece 13 (such as a bolt).

[0074] In the above technical solution, the prefabricated building components are made of materials commonly used in the current building field, and only need to be cut and welded to size, without the need for separate mold opening. The process is simple and the cost is low. Through the arrangement of the above connecting parts and limiting pieces, the standardization degree of the prefabricated building components is ensured, the technical difficulty of installation and disassembly is reduced, and the construction efficiency is improved.

[0075] Referring to the drawings Figure 5 The holding pole clamp 22 includes oppositely arranged first and second limiting plates 22.1 and 22.2, and the first and second limiting plates 22.1 and 22.2 are detachably connected with an eighth limiting piece 22.3. The building stand column 1 is located between the first and second limiting pieces 12 and 13, and the outer wall contacts the holding pole stand 20, the first and second limiting plates 22.1 and 22.2, and the eighth limiting piece 22.3.

The building stand column 1 is circumferentially limited by arranging the eighth limiting piece 22.3 in the bolt connection holes of the first and second limiting plates 22.1 and 22.2.

[0076] When connecting the lower column 1.2 and the upper column 1.1, the lower column 1.2 is first placed between the first limiting plate 22.1 and the second limiting plate 22.2. The eighth limiting member 22.3 is used to restrict the lower column 1.2 within the space enclosed by the first limiting plate 22.1, the second limiting plate 22.2, the eighth limiting member 22.3, and the support column 20 to prevent displacement. Then, the upper column 1.1 is lifted above the lower column 1.2 using the hoisting chain hoist 23. The bottom end of the upper column 1.1 is inserted into the lower column 1.2. The length of the upper column 1.1 inserted into the lower column 1.2 is adjusted according to the required building structure height. The two are then connected using the first limiting member 12.

[0077] When connecting the upper column 1.1 and the top edge beam 2.1, the lower column 1.2 is still held by the pole clamp 22, so the position of the building column 1 is fixed. At this time, the building connecting beam 2 is lifted to the top of the building column 1 by the hoisting chain hoist 23 in the adjacent pole quick assembly tool, and the top edge beam 2.1 and the upper column 1.1 are connected by the third limiting member 14.

[0078] The installation methods for building purlins 3, short columns 1.4, bottom edge beams 2.2, and bottom secondary beams 2.3 have been detailed above and will not be repeated here. After the building structure is connected and formed, disassemble the eighth limiting piece 22.3 to separate the separating pole clamp 22 from the building column 1. Move the pole-type quick-assembly tool laterally in a direction away from the building structure to separate the pole-type quick-assembly tool from the building structure, and then place the building structure on the ground.

[0079] It is worth noting that the pole-mounted quick-assembly tool in this technical solution is mainly used to replace large lifting equipment and provide the force required for lifting various prefabricated building components. However, the high-altitude position adjustment and bolt connection operations are still carried out manually at height. The construction methods and specifications are existing technologies in this field, so they will not be elaborated here.

[0080] To ensure the positional stability of the pole-mounted quick-assembly tool, a heavy-duty solid metal base 19 can be used, or limiting anchor bolts (not shown in the attached drawings) can be installed on or around the base 19 to ensure that the pole-mounted quick-assembly tool will not shift laterally during the connection of prefabricated building components.

[0081] The building is connected to the building column 1 to form a cubic frame; the building purlin 3 is lifted to the top of the cubic frame using the hoisting chain hoist 23 in the adjacent quick-assembly tool, and then the building purlin 3 is manually moved horizontally to the designated position and connected and secured to the cubic frame; after the building structure is connected and formed, the hoisting clamp 22 and the building column 1 are separated, and the quick-assembly tool is moved horizontally in a direction away from the building structure to separate the quick-assembly tool from the building structure, and the building structure is placed on the ground.

[0082] Compared with the prior art, the present application has at least the following beneficial effects: prefabricated building components are provided for forming a building structure (e.g. a main structure of a modular room), a pole-holding fast assembly tool is provided so that prefabricated building components are quickly assembled to form a building structure without the aid of large hoisting machinery, the fast forming system of the building structure is suitable for construction in special or limited construction areas, the construction efficiency is high and the cost is low, the connection joint design of the prefabricated building components is simple and highly standardized, and the building structure is easy to assemble and disassemble and can be recycled.

[0083] The above is the preferred embodiment of the present application. It should be pointed out that for ordinary skilled persons in the art, a number of improvements and refinements can be made without departing from the principles of the present application, and these improvements and refinements should also be considered within the scope of protection of the present application.
