Description

A kind of prefabricated building locking structure with strong stability

technical field

The utility model relates to the technical field of building components, in particular to a prefabricated building locking structure with strong stability.

Background technique

In the field of construction, aluminum alloy formwork is widely used due to its light weight, high recycling rate, high recycling value, strong environmental adaptability, good fire resistance, simple manual operation, high efficiency, short cycle and many other advantages. With the advancement of construction technology and aluminum processing technology, aluminum formwork has become the mainstream direction of application development in today's construction industry.

At present, the structure of aluminum profile building formwork is relatively solid. In practical application, due to the limitation of processing technology, the ideal state is often not achieved. When the formwork is installed, due to its own punching deviation, site ground height deviation, installation error and other factors, it will This causes positional offset between the formwork and the formwork, thereby reducing the flatness of the wall surface and affecting the construction quality.

The existing patent (publication number: CN207245180U) discloses an aluminum alloy building formwork interlocking structure. The building assembly locking device has a simple structure and a reasonable design. The second fixing slot is closed, and the U-shaped fixing block is buckled with the third fixing slot, which can effectively limit the relative displacement between the first connecting piece and the second connecting piece, and prevent the first connecting piece and the second connecting piece from offsetting each other. It is convenient and has high splicing precision, which can make the connection of adjacent aluminum formwork more tight and firm. It is compact and not easy to penetrate into concrete, which can greatly improve the flatness of the wall surface and ensure the construction quality.

However, the above-designed aluminum alloy building formwork interlocking structure still has some shortcomings in practical application: for example, the above-designed building formwork interlocking structure will use pins to stabilize after locking the first connector and the second connector. Positioning, since the building assembly board may need to be used in the outside world, the pins will change due to the principle of thermal expansion and cold contraction. When the outside temperature is too low, the pins will shrink slightly, which will cause the pins to produce gaps in the matching holes, thereby The stability of the first connector and the second connector cannot be guaranteed, and there is a great potential safety hazard, and the interlocking structure of the building formwork designed above is not easy to disassemble the pins, because the pins need to be tightly stuck in the assembly holes, if necessary Pulling out the pin requires a lot of force, which is time-consuming and labor-intensive, and has poor practicability.
