Referring to fig. 1, when the pressure relief pull tab 100 is fixed to the first mold plate 200 and the second mold plate 300, the connecting portion 11 is located between the first mold plate 200 and the second mold plate 300, and the fixing segment 20 is fixed to the first mold plate 200 and the second mold plate 300. Concrete is poured between the first form 200 and the second form 300, and the first form 200 and the second form 300 are used to form the concrete.

Referring to fig. 2, the connection segment 10 includes a connection portion 11 and a breaking portion 12, and the breaking portion 12 is disposed at two ends of the connection portion 11. The connecting section 10 is fixedly connected to the fixing section 20 via the break-off portion 12.

Referring to fig. 2, the pressure relief opening 111 is disposed on the connecting portion 11. When concrete is poured, the concrete passes through the pressure release tab 100 from the plurality of pressure release openings 111 to reduce the impact on the pressure release tab 100.

In an embodiment, four pressure relief openings 111 are formed in the connecting portion 11, and the four pressure relief openings 111 are arranged at equal intervals, so that the connecting portion 11 is stressed more uniformly when being impacted by the outside.

It is understood that the number of the pressure relief ports 111 is not limited thereto, and the number of the pressure relief ports 111 may be one, two, or three as in other embodiments. The connecting part 11 is provided with a plurality of pressure relief ports, and the pressure relief ports 111 are not required to be equidistant.

For example, when the number of the pressure relief openings 111 is within two, the thickness of the pressure relief pull tab 100 is greater than or equal to 2.5 mm; when the number of the pressure relief openings 111 is three, the thickness of the pressure relief pull tab 100 is greater than or equal to 3 mm; when the number of the pressure relief openings 111 is four, the thickness of the pressure relief pull tab 100 is greater than or equal to 3.5 mm.

In order to further prevent the rupture of the pressure relief tab 100, in one embodiment, the distance between the center lines of two adjacent pressure relief openings 111 is 70 mm. It is understood that the distance between the center lines of two adjacent pressure relief openings 111 is not limited thereto, and as in other embodiments, the distance between the center lines of two adjacent pressure relief tabs 100 may also be 75mm, 80mm, 85mm, 90mm, 95mm, 100mm, etc.

The pressure relief port 111 has a two-arc port 1111. The two circular arc ports 1111 are symmetrically arranged. In order to further enhance the breaking strength of the pressure relief pull tab 100, the distance between the centers of the two circular arc openings 1111 is less than or equal to 50 mm. In one embodiment, the distance between the centers of the circular arc openings 1111 is 50mm, but obviously, the distance is not limited thereto, and in other embodiments, the distance between the centers of the circular arc openings 1111 may also be 0mm, 5mm, 10mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, and the like.

When the first form 200 and the second form 300 are disassembled, the breaking part 12 is exposed outside the formed concrete, and in order to not affect the installation or the assembly of other structures, a force is applied to the pressure release pull tab 100 exposed outside, and the pressure release pull tab 100 is broken from the breaking part 12. The breaking is performed in the breaking part 12, which is common in the existing building scene, and is not described herein again.

In one embodiment, the break-off portion 12 is integrally formed with the connecting portion 11. It is understood that the fixing manner of the breaking part 12 and the connecting part 11 is not limited thereto, and as in other embodiments, the breaking part 12 and the connecting part 11 are welded.

Referring to fig. 2, the pressure relief pull tab 100 fixes the first mold plate 200 and the second mold plate 300 through the fixing segment 20, and in one embodiment, an end of the fixing segment 20 away from the connecting segment 10 is an arc end to prevent a worker from scratching when the fixing segment 20 is exposed outside.

The fixing section 20 is provided with a mounting hole 21. The mounting holes 21 are used to match the first mold plate 200 and the second mold plate 300, so as to fix the first mold plate 200, the second mold plate 300, and the fixing section 20. In one embodiment, the first and second templates 200 and 300 have pins fixed thereto, and the pins extend into the mounting holes 21 to fix the fixing sections 20 and the first and second templates 200 and 300. The mounting hole 21 is arranged in the middle of the fixed section 20, and the mounting hole 21 is a circular hole. It will be understood that the opening position of the mounting hole 21 depends on the position of the pin and varies with the position of the pin. The shape of the mounting hole 21 is not limited thereto, and as in other embodiments, the mounting hole 21 is a square hole.

Further, in order to increase the bending resistance of the pressure relief pull tab 100, the distance from the center of the mounting hole 21 to the center line of the adjacent pressure relief opening 111 is greater than or equal to 50 mm. In one embodiment, the distance from the center of the mounting hole 21 to the center line of the adjacent pressure relief opening 111 is 50mm, but obviously, the distance is not limited thereto, and as in other embodiments, the distance from the center of the mounting hole 21 to the center line of the adjacent pressure relief opening 111 may also be 55mm, 60mm, 65mm, 70mm, 75mm, 80mm, 85mm, 90mm, 95mm, 100mm, and the like. It is understood that the distance from the center of the mounting hole 21 to the center line of the adjacent pressure relief port 111 is not limited thereto.

Referring to fig. 1, in one embodiment, the first mold plate 200 and the second mold plate 300 are aluminum alloy mold plates, and the first mold plate 200 and the second mold plate 300 are substantially flat. It is understood that the type and shape of the first template 200 and the second template 300 are not limited thereto, and as in other embodiments, the first template 200 and the second template 300 are steel templates, and the shape of the first template 200 and the second template 300 is a triangular prism.

When the pressure relief pull piece 100 works, the two fixing sections 20 extend into the abutted seams of the first template 200 and the second template 300, pins arranged on the first template 200 and the second template 300 extend into the mounting holes 21, so that the pressure relief pull piece 100 is fixedly connected with the first template 200 and the second template 300, and a pouring cavity (not shown) is formed between the first template 200 and the second template 300.

Concrete is poured into the pouring cavity, and part of the concrete flows through the pressure relief pull tab 100 through the pressure relief opening 111, so that the impact strength of the concrete on the pressure relief pull tab 100 is reduced. After the concrete is solidified, the first formwork 200 and the second formwork 300 are disassembled, the fixed section 20 is exposed out of the concrete, and a tool is used for knocking the fixed section 20. The two fixing segments 20 are respectively broken along the breaking portion 12. At this time, the first form 200 and the second form 300 are fixed, and the connection section 10 is received in the formed concrete.

The pressure relief pull tab 100 provided above is provided with the plurality of pressure relief openings 111 on the connecting section 10, so that when concrete is poured, the concrete flows through the pressure relief pull tab 100 from the pressure relief openings 111, thereby increasing the bending resistance of the pressure relief pull tab 100.

In addition, those skilled in the art should recognize that the foregoing embodiments are illustrative only, and not limiting, and that appropriate changes and modifications to the foregoing embodiments may be made within the spirit and scope of the present disclosure.
