[0002] The prefabricated building technology has become an important direction of the development of modern building industrialization due to its fast construction speed, small environmental impact and recyclable materials. The common prefabricated wall is mainly assembled by light steel keel, prefabricated concrete slab or various light materials such as gypsum board and ALC board through bolt connection, welding or adhesion.

[0003] Although the prior art has achieved modular installation to some extent, in terms of connection reliability, most walls rely on discrete bolt nodes or simple plug-in structures, and the node strength is limited. When bearing horizontal load or accidental impact, stress concentration is easily generated at the connection, which leads to loosening or even failure, and there is a safety hazard. In terms of installation efficiency, the traditional installation process often requires construction personnel to align and tighten a large number of bolts one by one, which is tedious and difficult to achieve fast and large-scale standardized construction.

[0022] As Figure 14As shown, the height and length can be adjusted by increasing the number of assembled wall 2 based on the principle of the safety wall, and simultaneously increasing the number of third tenons 108 and connecting square tubes 104, horizontal square tubes 105, etc., and simultaneously increasing the length of the assembled frame 1. When increasing the height, a set of main drive wheels 10 system structure can link the upper and lower layers. The horizontal square tubes 105 of the remaining layers are not equipped with the main drive wheels 10 related transmission structure. The linkage rod 13 can be extended and the first locking rod 14 and the second locking rod 15 can be added. As needed, it can be changed to link several layers above and below. When increasing the length, it is also done by a set of main drive wheels 10, and so on. like Figure 15 As shown, when expansion is required, the assembled wall 2 can be adjusted as needed. Linear mortises 3 can be left on both sides, and mortises 4 can be left at the corners on the other two sides to accommodate the requirements of the middle-layer assembled wall 2 when the overall height increases.

[0023] Working principle: During assembly, it is possible to decide whether to install a ground joist as needed. It can be directly erected on the ground, or the base plate 102 can be fixedly connected to the ground joist. The top plate 101 can also be fixedly connected to the suspended ceiling or ceiling, or it can be left untouched. After the assembly frame 1 is set up, the assembly wall 2 can be inserted into the assembly frame 1. Simply align the linear mortise 3 of each assembly wall 2 with the first tenon 106, the second tenon 107, and the third tenon 108 of the assembly frame 1 respectively. During the process, insert each connecting tenon 7 simultaneously, and then install the end tenon 6 and side plate 109 on both sides of the safety wall. Next, use a socket wrench to connect with the polygonal pin 17 and rotate it to make the main drive wheel 10 rotate. The main drive wheel 10 pulls the driven rod 11 to rotate through the transmission rod 12. The two driven rods 11 rotate synchronously and push the linkage rod 13 upward. The linkage rod 13 cooperates with the first locking rod 14 to pull the second locking rod 15. After adjusting the position of the second locking rod 15 to ensure that the bolt hole is aligned with the pin hole 5 of the assembly wall 2, the screw pin 16 can be installed. After connecting the second locking rod 15 to the assembly wall 2, connect each panel 110 to the short telescopic rod 1502 connected to the ball hinge 1501 with bolts. Then, neatly assemble the panels 110 onto the assembly frame 1 with bolts. Finally, move the locking plate 21 by the handle 24. When it moves to the circular opening of the limit port 26, the telescopic section of the spring telescopic rod 22 will pop out and lock, and the locking plate 21 will stick to the one-way tooth of the main drive wheel 10. Then, rotate the main drive wheel 10 clockwise by the socket wrench to drive each second locking rod 15 to pull the assembly wall 2 and press against it in turn until the locking plate 21 locks the ratchet tooth of the main drive wheel 10. The ball hinge 1501 will also be pulled and locked by the short telescopic rod 1502 along with the second locking rod 15, thus realizing the interlocking and fixing between each assembly wall 2.

[0024] Finally, it should be noted that the above only describes the preferred embodiments of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art will appreciate that the technical solutions described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalent ones. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
