[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-7 One embodiment provided by this utility model:

[0025] A formwork installation clamp for building assembly includes a first clamping arm 1 and a second clamping arm 2. A rotating column 3 is provided at the connection between the first clamping arm 1 and the second clamping arm 2. A cable 4 is connected to one end of the first clamping arm 1 and the second clamping arm 2. A lifting ring 5 is sleeved on the end of the cable 4 away from the first clamping arm 1 and the second clamping arm 2. A circular hole is opened through the surface of the first clamping arm 1 and the second clamping arm 2, and a fixing ratchet block 6 is provided on the inner wall of the circular hole. A pressing rod 31 is slidably connected to the surface of the rotating column 3. A baffle 32 is fixedly connected to the surface of the pressing rod 31. A control rod 33 is fixedly connected to the surface of the baffle 32. A support rod 34 is slidably connected to the surface of the control rod 33. A connecting groove 35 is opened on the outer surface of the control rod 33. A movable plate 36 is movably connected to the inner side of the connecting groove 35. A movable block 61 is movably connected to the surface of the movable plate 36. An extension rod is sleeved on the surface of the movable block 61. The telescopic rod 62 has a movable ratchet block 64 fixedly connected to its surface, and a telescopic spring 63 sleeved on its outer surface. Movable grooves 7 are provided at the ends of the first clamping arm 1 and the second clamping arm 2 away from the cable 4. An adjusting plate 71 is inserted into the inner side of the movable groove 7. A fixed plate 72 is fixedly connected to the surface of the adjusting plate 71, and a support plate 73 is fixedly connected to the surface of the fixed plate 72. An insertion hole 74 is provided through the surface of the adjusting plate 71, and a pin 75 is connected through the inner side of the insertion hole 74. Through the connection between the first clamping arm 1 and the rotating column 3, and the connection between the second clamping arm 2 and the rotating column 3, the rotational connection between the first clamping arm 1 and the second clamping arm 2 is achieved under the action of the rotating column 3. The abutting contact between the movable ratchet block 64 and the fixed ratchet block 6 achieves unidirectional control of the rotation direction of the first clamping arm 1 and the second clamping arm 2, improving their clamping stability.

[0026] Furthermore, the first clamping arm 1 and the second clamping arm 2 have the same shape and are staggered. The first clamping arm 1 and the second clamping arm 2 are rotatably connected by the rotating column 3. Through the rotatable connection of the first clamping arm 1 and the second clamping arm 2, the clamping and hoisting operation of the building assembly formwork is realized. Under the action of the cable 4 and the lifting ring 5, the hoisting and transportation effect of the formwork after being clamped by the first clamping arm 1 and the second clamping arm 2 is achieved.

[0027] Furthermore, the cable 4 is connected in two sets to the first clamping arm 1 and the second clamping arm 2. The inside of the rotating column 3 is provided with a circular groove, and the pressing rod 31 passes through the circular groove and is fixedly connected to the baffle 32. The baffle 32 and the circular groove abut against each other. Through the connection between the rotating column 3 and the pressing rod 31, the position of the control rod 33 in the rotating column 3 can be adjusted under the action of the pressing rod 31.

[0028] Furthermore, the support rod 34 and the rotating column 3 are fixedly connected. The end of the control rod 33 away from the pressing rod 31 has a round hole. The support rod 34 is inserted into the control rod 33 through the round hole. A spring is sleeved on the outer surface of the support rod 34. Through the insertion of the support rod 34 and the control rod 33, under the action of the spring on the support rod 34, the elastic connection effect between the support rod 34 and the control rod 33 is achieved, so that the control rod 33 can slide elastically within the rotating column 3.

[0029] Furthermore, the movable block 61 is movably connected to the control rod 33 via the movable plate 36, and the movable ratchet 64 penetrates the surface of the rotating column 3. The movable ratchet 64 is elastically slidably connected to the movable block 61 via the telescopic rod 62 and the telescopic spring 63. Through the connection of the control rod 33 and the connecting groove 35, and under the connection of the connecting groove 35 and the movable plate 36, when the position of the control rod 33 changes, the angle of action of the movable plate 36 changes. At this time, the position of the movable ratchet 64 in the rotating column 3 changes, and the movable ratchet 64 and the fixed ratchet 6 separate, releasing the control of the unidirectional rotation between the first clamping arm 1 and the second clamping arm 2.

[0030] Furthermore, the movable ratchet 64 penetrates the surface of the rotating column 3 and abuts against the fixed ratchet 6. The adjusting plate 71 penetrates the surface of the first clamping arm 1 and the second clamping arm 2 through the movable groove 7. The support plate 73 acts below the first clamping arm 1 through the adjusting plate 71 and the fixed plate 72. Through the connection between the movable groove 7 and the adjusting plate 71, the position of the support plate 73 is adjusted and supported under the action of the adjusting plate 71.

[0031] Furthermore, the insertion holes 74 are evenly distributed on the surface of the adjusting plate 71, and the pin 75 is in the shape of a "T". The pin 75 is connected to the adjusting plate 71 through the insertion holes 74. With the connection between the adjusting plate 71 and the insertion holes 74, the pin 75 is inserted into the insertion holes 74 at different positions, so as to realize the adjustment effect of the position of the adjusting plate 71 in the movable groove 7, and improve the application range and performance of the support plate 73.

[0032] Working principle: When hoisting the assembly template, hoisting equipment is used, connected to lifting ring 5. Under the action of cable 4, when the template is lifted, the cable 4 pulls on the first clamping arm 1 and the second clamping arm 2, causing the first clamping arm 1 and the second clamping arm 2 to rotate. At this time, under the action of the support plate 73, the template is clamped. Under the abutting contact of the movable ratchet block 64 and the fixed ratchet block 6, the first clamping arm 1 and the second clamping arm 2 rotate in one direction and will not rotate in the opposite direction. This can effectively clamp the template and prevent it from easily falling off. When the template is hoisted to the appropriate position, press the pressing rod 31, and the movable ratchet block 64 and the fixed ratchet block 6 separate. At this time, the support plate 73 is separated from the template, thus completing the hoisting and separation operation of the template. Repeat the above operation to complete the repeated hoisting construction.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
