[0002] The pull-sheet aluminum alloy formwork is designed based on the module and is extruded by special equipment. It adopts a new formwork system that combines disposable pull-sheets with a series of reinforcement systems such as square tubes, diagonal braces, and small diagonal braces. The pull-sheets are made of high-strength manganese steel. The general specifications are 326X33X2mm and the tensile strength is

[0003] >800MPa, each pull tab can withstand a tensile force of 3 tons, with round holes at both ends, installed at the joints of the aluminum formwork, and connected to the side ribs of the aluminum formwork through pins. After the aluminum formwork is demolded, the pull tab head exposed on the wall is broken off, and the main body of the pull tab remains inside the concrete.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] like Figures 1 to 5 As shown, the utility model provides an aluminum film pull tab removal device, comprising a combined handle 1 and a removal end 2, wherein the end of the combined handle 1 is threadedly connected to the removal end 2;

[0030] The removal end 2 includes a cylinder 201, which is provided with a through slot 202 that matches the aluminum film pull tab. The end of the pull tab is inserted into the through slot 202, and the combination handle 1 is pressed downward or pushed upward to apply force to the connection point between the pull tab and the wall, thereby breaking the pull tab, making the removal process convenient and quick.

[0031] The combination handle 1 includes a hollow short handle 101 and a hollow long handle 102. The hollow short handle 101 is threadedly connected to the hollow long handle 102. The end of the hollow short handle 101 away from the hollow long handle 102 is threadedly connected to the cylinder 201. The broken pull tabs can enter the internal space of the combination handle 1 to facilitate the collection of the removed pull tabs. After accumulating to a certain number, they are discharged in a centralized manner. In addition, the hollow short handle 101 cooperates with the hollow long handle 102 to remove pull tabs at a higher position, which is beneficial to the use of the device.

[0032] Specifically, the inner wall of the front end of the through slot 202 is fixed with serrations 3 correspondingly arranged at the upper and lower ends. The serrations 3 are more convenient for clamping the pull tab, which is conducive to easily breaking the pull tab.

[0033] Furthermore, a first threaded protrusion 4 is fixed to the end of the hollow short handle 101 corresponding to the cylinder 201, and a first threaded groove 5 is opened at the position corresponding to the cylinder 201 and the hollow short handle 101. The first threaded groove 5 is threadedly connected to the first threaded protrusion 4. The first threaded protrusion 4 fixedly connected to the hollow short handle 101 is screwed into the first threaded groove 5 on the cylinder 201 to connect the hollow short handle 101 to the dismantling end 2.

[0034] Furthermore, a second threaded protrusion 6 is fixed at one end corresponding to the hollow short handle 101 and the hollow long handle 102, and a second threaded groove 7 is provided on the hollow long handle 102 at a position corresponding to the hollow short handle 101. The second threaded groove 7 is threadedly connected to the second threaded protrusion 6. The second threaded protrusion 6 fixedly connected to the hollow short handle 101 is screwed into the second threaded groove 7 of the hollow long handle 102, so that the hollow short handle 101 and the hollow long handle 102 can be connected, so as to facilitate the removal of the pull tab at a high place.

[0035] It is worth noting that a rubber plug 8 is provided at the tail end of the combination handle 1. The inner diameter of the combination handle 1 is larger than the height of the through groove 202. The rubber plug 8 blocks the tail end of the hollow short handle 101 or the tail end of the hollow long handle 102 to prevent the pull tab from slipping out. After a certain number of pull tabs are accumulated, the rubber plug 8 can be removed to allow the pull tab to be discharged.

[0036] It is worth noting that an annular anti-slip protrusion 9 is provided on the outer side of the inserted portion of the rubber plug 8 , and a pull ring 10 is provided on the side of the rubber plug 8 away from the combined handle 1 .

[0037] It is worth mentioning that the length of the hollow short handle 101 is set to 300 mm, the length of the hollow long handle 102 is set to 1200 mm, and the bending angle of the end of the hollow long handle 102 is set to 130 degrees.

[0038] Working principle and process: The worker holds the combination handle 1, aligns the removal end 2 with the pull tab at the high position of the wall, and extends the end of the pull tab into the through groove 202 on the cylinder 201, presses down or pushes the combination handle 1 upward, so that the connection point between the pull tab and the wall is subjected to force, thereby breaking the pull tab, adjusting the position of the tool so that the broken pull tab passes through the through groove 202 and enters the interior of the combination handle 1. After accumulating a certain number of pull tabs, open the rubber plug 8 to discharge the collected pull tabs. When removing the pull tabs at a lower position on the wall, rotate the hollow long handle 102 so that the second threaded protrusion 6 on the hollow short handle 101 is unscrewed from the second threaded groove 7 of the hollow long handle 102, and the hollow long handle 102 can be removed, leaving only the hollow short handle 101, and remove the rubber plug 8 and insert it into the tail end of the hollow short handle 101. Repeat the pull tab removal steps, and the pull tab can be removed and stored in the hollow short handle 101, effectively improving the pull tab removal efficiency.
