Technical field:

[0001] The utility model relates to the technical field of building templates, in particular to a quick disassembly structure of an engineering template. Background technology:

[0002] In civil engineering and construction machinery construction, construction formwork plays a vital role. It is a temporary structure used to ensure that concrete structures or components can be formed according to the position and geometric dimensions required by the design, and bear their own weight and external loads. With the advancement of construction technology, architectural aluminum formwork has gradually become dominant in modern high-rise buildings due to its recyclable and reusable characteristics, replacing traditional wooden baffle structures.

When disassembling, a large number of bolts need to be removed one by one, which is not only time-consuming and labor-intensive, but also has low disassembly efficiency, which seriously affects the progress of the project. Therefore, a rapid disassembly structure of the engineering formwork is proposed. Utility model content:

[0030] The working principle or structural principle is that when it is necessary to disassemble the two templates, the two levers 30 are squeezed together to move the two sliders 20 together, thereby driving the two plug blocks 21 to slide out of the two slots 22 at the same time, thereby releasing the limit on the pin 17. At this time, the limit ring 25 is pushed to move by the thrust of the return spring 26, thereby driving the push-pull block 16 to move, thereby driving the two pins 17 on the push-pull block 16 to slide out of the adjacent pin holes 15 at the same time, thereby releasing the limit on the second connecting frame 14, and removing the second connecting frame 14. The lower second template 12 is disassembled; when the two templates need to be assembled, the first template 11 and the second template 12 are brought close to each other so that the pin holes 15 on the first connecting frame 13 and the second connecting frame 14 are aligned, and the push-pull block 16 is pushed to drive the two pins 17 to be inserted into the adjacent pin holes 15 at the same time, and the two levers 30 are released. Under the thrust of the push spring 27, the two sliders 20 are pushed to move closer to each other, thereby driving the two insert blocks 21 to be inserted into the slots 22 on the two pins 17 at the same time, and then the pins 17 are limited and fixed to complete the assembly.
