[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model discloses a fastening device for aluminum formwork construction templates.

[0025] This utility model provides, for example Figure 1-3 The aluminum formwork construction template fastening device shown includes two first aluminum templates 1. Two slots are opened on the side of the two first aluminum templates 1 that are close to each other. A second aluminum template 2 is inserted between the two corresponding slots. Two square frames 3 are sleeved on the outer surface of the two first aluminum templates 1. A pressure plate 4 is slidably arranged inside the two square frames 3. An adjustment mechanism is provided between the two pressure plates 4 and the corresponding square frames 3. The pressure plates 4 are moved by the adjustment mechanism. A limit mechanism is provided on one side of the square frame 3. The adjustment mechanism matches the limit mechanism.

[0026] To secure the two aluminum templates, such as Figure 1-3 As shown, the adjustment mechanism includes two lead screws 5, two sleeves 6, and two rotating plates 7. Each of the two square frames 3 has a first through hole on one side. The two lead screws 5 are rotatably connected to the inside of the corresponding first through hole. The two sleeves 6 are threaded onto the rod wall of the corresponding lead screw 5. The two rotating plates 7 are fixedly connected to one end of the corresponding lead screw 5. The sleeves 6 are fixedly connected to one side of the pressure plate 4.

[0027] The rotating plate 7 drives the lead screw 5 to rotate, and the sleeve 6 pushes the clamping plate 4 to move towards the template along the axis of the lead screw. The clamping plate is tightly attached to the template surface. The template can be fastened in two directions by applying force on one side, which reduces the operation steps compared with the traditional double-sided fastening method, thereby improving the efficiency of template fastening.

[0028] To prevent the rotating plate 7 from being fixed after rotation, such as Figure 1-3As shown, the limiting mechanism includes two fixed frames 8, two insert rods 9, two stops 10, two pull rings 11, and two springs 12. The two fixed frames 8 are respectively fixedly connected to one side of the corresponding rotating plate 7. A second through hole is opened at one end of each of the two fixed frames 8. The two insert rods 9 are respectively inserted into the interior of the corresponding second through hole. The two stops 10 are respectively fixedly sleeved on the rod wall of the corresponding insert rod 9. The two springs 12 are respectively slidably sleeved on the rod wall of the corresponding insert rod 9. The two pull rings 11 are respectively fixedly connected to one end of the corresponding insert rod 9. A slot is opened on one side of each of the two square frames 3. One end of each insert rod 9 passes through one side of the corresponding rotating plate 7 and matches the corresponding slot.

[0029] When the pressure plate reaches the preset pressure, the spring 12 of the limit mechanism pushes the stop 10, so that the insert rod 9 is inserted into the slot of the square frame and the position of the rotating plate is locked. When disassembling, pull the pull ring 11 to drive the insert rod out of the slot, rotate the rotating plate in the opposite direction to make the pressure plate disengage from the template, and then the square frame can be removed.

[0030] In order for the clamping plate to move stably, such as Figure 1 As shown, telescopic rods 13 are symmetrically fixedly connected between the two clamping plates 4 and the corresponding square frames 3.

[0031] The telescopic rod 13 ensures stable translation of the clamping plate and avoids clamping deviation caused by radial force of the screw.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
