Description

Technical Field

[0001] The utility model belongs to the field of concrete construction, and particularly relates to a tool for removing aluminum formwork pull tabs. Background Technique

[0002] The aluminum formwork pull tab is a fixing technique when using aluminum alloy molds to manufacture concrete structures. It is mainly used in construction projects, especially at the joints of floor slabs and beam-columns in high-rise buildings. Compared with the traditional screw system, the aluminum formwork pull tab does not require drilling, and no holes will be left on the wall after form removal, thus significantly reducing the risk of external wall leakage. This technique has the advantages of excellent construction quality, high installation efficiency, and low cost.

[0003] However, the steel pull tabs used in the aluminum formwork pull tab system are disposable. After pouring is completed, both ends of the pull tab will be exposed outside, and usually, workers need to manually remove these pull tabs, which is time-consuming and laborious. In addition, workers usually use the method of knocking to remove the pull tabs, which may damage the concrete surface. Content of the Utility Model

[0019] The following describes in detail the specific implementation of the present utility model in conjunction with specific embodiments.

[0020] As Figures 1 to 4 shown, a tool for removing aluminum formwork pull tabs provided by an embodiment of the present utility model includes a device main body 1, and further includes:

[0021] A shearing unit 2, the shearing unit 2 includes a shearing block 3 arranged in the device main body 1, sliding blocks 31 integrally formed with the shearing block 3 are arranged on the upper and lower sides of the shearing block 3, a sliding groove 311 is fixedly arranged at a position corresponding to the sliding block 31 on the inner side of the device main body 1, a movable hole 32 is fixedly arranged on one side of the shearing block 3, a movable rod 4 is movably arranged in the movable hole 32, a spring 5 is movably sleeved on the outer side of the movable rod 4, one end of the movable rod 4 is fixedly connected with a pressing block 6, the pressing block 6 is movably arranged in the sliding groove 311, and a cutter 7 for shearing the pull tab is also fixedly arranged on one side of the shearing block 3;

[0022] A driving unit 8, the driving unit 8 includes a driving block 9 movably arranged on one side of the shearing block 3, one end of a lead screw 10 is fixedly arranged on one side of the driving block 9, a mounting hole 101 adapted to the outer diameter of the lead screw 10 is fixedly arranged on the side wall of the device main body 1 corresponding to the lead screw 10, the other end of the lead screw 10 penetrates through the mounting hole 101 and extends to the outside of the device main body 1, a sleeve 11 is sleeved on the outer side section of the lead screw 10, the sleeve 11 is fixedly connected with the motor spindle in a driving drill 12, a fixing member 121 fixedly connected with the driving drill 12 is also arranged on the outside of the device main body 1, and a grip 13 for holding is also arranged on one side of the driving drill 12.

[0023] In an embodiment of the present utility model, by arranging the lead screw 10 in cooperation with the sleeve 11, it is convenient to control the movement of the driving block 9, and by controlling the movement of the shearing block 3, the cutter 7 shears both ends of the aluminum formwork pull tab. By arranging the spring 5 in cooperation with the pressing block 6, the aluminum formwork pull tab can be pressed tightly during the shearing process to prevent bending deformation from affecting the shearing work, and the shearing block 3 can be reset by rebounding after the driving block 9 is reset.

[0024] As Figures 3 to 4 shown, as a preferred embodiment of the present utility model, the device main body 1 is arranged as a hollow block structure, both sides of the device main body 1 are penetrated, the shearing block 3 is integrally arranged as a block structure, the sliding block 31 is arranged as a rectangular block, and the sliding block 31 is movably arranged in the sliding groove 311.

[0025] Furthermore, the movable rod 4 is arranged as a columnar structure, the movable hole 32 is arranged as a through hole adapted to the cross section of the movable rod 4, one side of the pressing block 6 is provided with an inclined surface, and the outer side of the cutting knife 7 is flush with the side surface of the device main body 1.

[0026] In an example of the present utility model, by movably arranging the set slider 31 in the chute 311, the moving direction of the shearing block 3 is restricted, facilitating the control of the movement of the shearing block 3 to further control the cutting of the end of the aluminum mold tab by the cutting knife 7. By arranging the movable rod 4 and the movable hole 32, the bending deformation of the pressing block 6 can be restricted to ensure the extrusion effect. By making the outer side of the cutting knife 7 flush with the side surface of the device main body 1, the fracture of the aluminum mold tab after cutting can be made flush with the concrete surface.

[0027] As Figure 2 shown, as a preferred embodiment of the present utility model, one side of the driving block 9 is provided with an inclined surface, and one side of the shearing block 3 is provided with an inclined surface having the same slope as the inclined surface on the side of the driving block 9 corresponding to the inclined surface on the side of the driving block 9.

[0028] In an example of the present utility model, through the two inclined surfaces arranged on the side surfaces of the shearing block 3 and the driving block 9, the left and right movement of the shearing block 3 can be controlled under the extrusion action of the two inclined surfaces, facilitating the control of the movement and cutting of the cutting knife 7.

[0029] As Figure 2 shown, as a preferred embodiment of the present utility model, the inner side of the sleeve 11 is provided with a thread adapted to the outer side of the lead screw 10.

[0030] In an example of the present utility model, by the cooperation of the arranged sleeve 11 and the lead screw 10, the movement of the lead screw 10 can be controlled by controlling the rotation of the sleeve 11, and further the movement of the driving block 9 can be controlled.

[0031] In an example of the present utility model, during use, the end of the aluminum formwork pull tab is inserted into the opening on one side of the cutter 7 on the device main body 1. Under the action of the spring 5 and the pressing block 6, the end of the aluminum formwork pull tab is pressed tightly. The driving drill 12 is started to drive the sleeve 11 to rotate. Under the meshing action of the sleeve 11 and the lead screw 10, the lead screw 10 moves and drives the driving block 9 to extrude the shearing block 3. Through the extrusion of the inclined surface on one side of the driving block 9 and the inclined surface on one side of the shearing block 3, and restricted by the slider 31 and the sliding groove 311, the shearing block 3 makes a lateral movement, further extruding the pressing block 6 and pressing the end of the aluminum formwork pull tab tightly through the spring 5. As the shearing block 3 moves, the end of the aluminum formwork pull tab is sheared by the cutter 7 arranged on one side of the shearing block 3. The driving drill 12 is reversed to retract the driving block 9, and the shearing block 3 is reset under the action of the spring 5 and the pressing block 6. At this time, the broken end of the aluminum formwork pull tab is pressed tightly in the device main body 1 without being taken out, and the shearing of the next end of the aluminum formwork pull tab can be directly carried out. When the next end of the aluminum formwork pull tab is inserted into the device main body 1, the broken end of the aluminum formwork pull tab in the device main body 1 can be extruded and dropped out from the other end of the device main body 1.
