[0029] Embodiment 2

[0030] Please refer to Figure 5 and Figure 6On the basis of Example 1, the first connecting member 3 includes a panel 31, a frame 32 and a back panel 33. The panel 31 and the back panel 33 are respectively fixed to the front and rear sides of the frame 32. The frame 32 is a square structure with a hollow interior. A swastika-shaped bracket 35 is fixed inside the frame 32.

[0034] Working principle:

[0035] When in use, first place two aluminum alloy templates 1 adjacent to each other on the left and right sides so that the two adjacent half-mortise grooves 2 are combined into a complete mortise groove, and then embed the first connecting piece 3 into the mortise groove. When embedding, it is necessary to manually pull the first positioning column 36 and the second positioning column 37 inward. After embedding, release the lever 38. Under the action of the reset spring 310, the first positioning column 36 and the second positioning column 37 will be reset and inserted into the corresponding positioning hole 21. At this time, the two adjacent aluminum alloy templates 1 on the left and right sides will be spliced ​​together to form a whole aluminum alloy template wall. Through the use of the mortise groove and the first connecting piece 3, the templates can be quickly disassembled and assembled to form a whole aluminum alloy template wall.

[0036] The single-layer aluminum alloy formwork wall has low strength. During building construction, a multi-layer formwork structure is generally adopted to enhance the building strength. At this time, the two assembled whole aluminum alloy formworks can be assembled front and back again. By using the pre-opened holes on the formwork surface in cooperation with the stud 41, the front and back formwork walls are pre-fixed first, and then the nut sleeve 43 is screwed tightly at both ends of the stud 41, so that the front and back formwork walls can be connected and fixed. When one side of the formwork wall is impacted, it will slide towards the other side of the formwork wall. When sliding, it will squeeze the buffer spring 42, and the buffer spring 42 can buffer the pressure to buffer and protect the wall.
