Description

Technical Field

[0001] The present invention relates to the technical field of rail transit construction, and particularly to a prefabricated detachable wall structure. Background Art

[0002] In the design and construction of rail transit projects, setting fixed walls for equipment transportation channels is a key link to ensure the safety and convenience of later operation and maintenance. Currently, the common solutions are to open transportation holes in the fixed walls of the equipment transportation path and use fireproof rolling shutters or detachable brick walls for closure. However, both of these methods have significant technical defects. The main problems of the fireproof rolling shutter solution include: the rolling shutter is prone to aging and wear, resulting in a service life far lower than that of the main building structure, and its fire resistance is poor. The limitations of the detachable brick wall solution are manifested as: low disassembly and assembly efficiency, repeated disassembly and modification are likely to damage the connection parts of the main structure, affecting the integrity of the building; poor flexibility, unable to meet the requirements of temporary and repeated disassembly and assembly. There are also detachable wall structures used to block transportation holes in the prior art. However, in order to ensure the stability of the detachable wall after installation, concrete retaining sills or embedded bolts need to be set in the installation holes, which will cause a protruding part that is difficult to disassemble at the bottom of the transportation hole (i.e., the ground), which will have an adverse impact on subsequent equipment transportation. Moreover, the installation process of the existing detachable wall structure is complex, affecting the construction efficiency. Therefore, there is an urgent need for a prefabricated detachable wall structure with stable structure, convenient disassembly and assembly and not affecting subsequent equipment transportation.

Both the upper limiter and the lower limiter include two limit plates. The two limit plates are detachably fixed to the top and bottom of the transportation hole, thereby forming upper and lower limit card slots. The upper and lower ends of the wall panel body are limited in the limit card slots to form a detachable wall structure. The detachable wall structure can achieve rapid positioning and fixing of the wall without complex construction processes, and can significantly improve the construction efficiency.

[0017] The prefabricated and detachable wall structure adopts a threaded connection method of a fixed screw sleeve and a fastening bolt. The fixed screw sleeve is embedded in the fixed wall (i.e., the inner wall of the transportation hole), which can ensure the firm fixation of the upper limit plate and the lower limit plate in the transportation hole, with high stability. Moreover, the way of embedding the fixed screw sleeve can ensure that the ground is flat after the wall structure is disassembled, and it is possible to avoid setting a protruding part at the bottom of the transportation hole (i.e., the ground) that is difficult to disassemble, so as to ensure that the equipment can be conveniently transported through the transportation hole.

[0027] The wall panel body 2 includes a fixed frame body and two wall panel bodies 23. The two wall panel bodies 23 are respectively fixed to the front and rear sides of the fixed frame body, so that a filling cavity is formed inside the wall panel body 2, and the filling cavity is filled with a fireproof filler 25. The fireproof filler 25 can be a rock wool material.

[0028] The limiting plate 3 is fixed to the fixed wall 1 (i.e., the inner wall of the transportation hole 11) through the structure of a fixed screw sleeve 4 and a fastening bolt 5. The fixed screw sleeves 4 are fixedly buried at the top and bottom of the inner wall of the transportation hole 11. The inner wall of the fixed screw sleeve 4 is provided with an internal connection thread. Installation holes are provided on both the upper limiting plate 3 and the lower limiting plate 3.
