[0001] The utility model relates to the technical field of building construction, in particular to a building construction formwork clamp. Background Technique

[0002] A building formwork is a temporary support structure, which is a formwork and support for concrete pouring, so that the concrete structure and components are formed according to the designed dimensions and positions. In actual use, multiple formworks usually need to be cut, spliced and fixed into the required shape, and nails, tie bolts or clamps are usually used to fix the formworks.

[0003] A building construction formwork furniture provided by application number 201921730673.7 includes a straight rod, a clamping plate is fixedly connected to the left end of the straight rod, a first plastic pad is fixedly connected to the front part of the right end of the clamping plate, a plurality of limiting grooves are opened at the rear end of the straight rod, a clamping block is inserted through the middle of the straight rod, a turntable is arranged at the rear end of the clamping block, a connecting rod is fixedly connected to the front end of the clamping block, and the connecting rod is parallel to the clamping plate. An adjusting component is arranged at the front end of the connecting rod, a connecting block is fixedly connected to the left end of the adjusting component, a second plastic pad is fixedly connected to the left end of the connecting block, and plastic anti-slip blocks are fixedly connected to the opposite surfaces of the first plastic pad and the second plastic pad.

[0004] This device uses a screw rod to adjust the height of the limiting strip, so as to conveniently adjust the position of the clamping block on the straight rod, and uses a rotating handle to rotate the lead screw to adjust the distance between the first plastic pad and the second plastic pad, so as to clamp the formwork. However, in actual application, the formwork will be impacted during concrete pouring, and the volume will change due to heat generation when the concrete solidifies. Therefore, the clamp needs to apply a large pressure to the formwork first. Only by rotating the handle to adjust the distance between the two plastic pads, the applied pressure is not enough to cope with the deformation caused by the solidification of the concrete, and finally the formwork will bulge.

[0032] Embodiment 1:

[0033] Please refer to Figures 1-5 , the above technical solution of the present utility model is described in detail through the following embodiments:

[0034] A building construction formwork fixture, comprising:

[0035] A fixed fixture 1, the fixed fixture 1 includes a fixed bar 11, a fixed chuck 13 is fixedly installed at the head of the fixed bar 11 through a clamping plate 12, and a movable fixture 2 is slidably installed in the middle of the fixed bar 11. A quick adjustment component 3 is connected between the movable fixture 2 and the fixed bar 11.

[0036] The fixed bar 11 is inserted into the head of the clamping plate 12 and then welded to the clamping plate 12. The fixed chuck 13 is welded and installed on the bottom of the clamping plate 12 on the side facing the fixed bar 11. The fixed chuck 13 is used to contact the formwork.

[0037] A tooth groove 14 is provided on the top surface of the fixed bar 11, and the tooth groove 14 is inclined towards the clamping plate 12.

[0038] Both sides of the tooth groove 14 do not penetrate the fixed bar 11.

[0039] A limit sleeve 15 is provided at the tail of the fixed chuck 13.

[0040] The limit sleeve 15 is made of plastic and is fixedly installed at the tail of the fixed chuck 13 by screws.

[0041] The movable fixture 2 includes a sliding sleeve 21, the sliding sleeve 21 is slidably connected to the fixed bar 11, a movable chuck 24 is provided below the sliding sleeve 21 through a second clamping plate 22, and a pressure application component 4 is provided between the movable chuck 24 and the second clamping plate 22.

[0042] The limit sleeve 15 is used to limit the sliding distance of the sliding sleeve 21.

[0043] The second clamping plate 22 is welded and installed at the bottom of the sliding sleeve 21, and the movable chuck 24 is located on the bottom of the second clamping plate 22 on the side facing the fixed chuck 13. The movable chuck 24 is used to cooperate with the fixed chuck 13 to clamp the formwork.

[0044] The quick adjustment assembly 3 includes a ratchet plate 31 which is slidably installed in the sliding sleeve 21. The ratchet plate 31 is used to engage with the fixed strip 11 to fix the sliding sleeve 21. A quick detachment assembly is provided between the ratchet plate 31 and the sliding sleeve 21, and the quick detachment assembly is used for the quick release of the ratchet plate 31 and the fixed strip 11. The ratchet plate 31 meshes with the tooth groove 14.

[0045] Since the tooth groove 14 is inclined towards the clamping plate 12, the sliding sleeve 21 cannot move away from the fixed fixture 1 when the ratchet plate 31 meshes with the tooth groove 14.

[0046] The quick detachment assembly includes two guide shafts 32 and an adjustment shaft 33. One ends of the guide shafts 32 and the adjustment shaft 33 are welded to the ratchet plate 31, and the other ends are slidably connected to the top of the sliding sleeve 21. A compression spring 34 is sleeved on the guide shaft 32.

[0047] The guide shafts 32 and the adjustment shaft 33 can limit the sliding direction of the ratchet plate 31. Two ends of the compression spring 34 respectively abut against the ratchet plate 31 and the inner top of the sliding sleeve 21. The elastic force of the compression spring 34 ensures that the ratchet plate 31 and the tooth groove 14 remain in contact.

[0048] When an external force to the left acts on the sliding sleeve 21, it will slide towards the fixed chuck 13. Thus, the ratchet plate 31 will slide upwards under the inclined extrusion of the tooth groove 14, and then move downwards under the elastic force of the compression spring 34 to remain in contact with the tooth groove 14. At the same time, the second clamping plate 22 and the movable chuck 24 will move along with the sliding sleeve 21, so as to quickly shorten the distance between the fixed chuck 13 and the movable chuck 24, realizing the quick clamping of the template.

[0049] The head of the adjustment shaft 33 penetrates through the head of the sliding sleeve 21, and an eccentric handle 35 is rotatably installed at the head of the adjustment shaft 33 through a connecting shaft 36.

[0050] Rotating the eccentric handle 35 upwards can drive the adjustment shaft 33 to move outwards, so as to drive the ratchet plate 31 away from the tooth groove 14, realizing the detachment of the ratchet plate 31 and the tooth groove 14. At this time, the sliding sleeve 21 can slide freely along the fixed strip 11, realizing the quick release of the template.

[0051] A slide bar 23 is welded to the back of the movable chuck 24, and the slide bar 23 is slidably connected to the tail of the second clamping plate 22.

[0052] The movable chuck 24 can slide relative to the second clamping plate 22 through the slide bar 23. The slide bar 23 is used to limit the sliding direction of the movable chuck 24.

[0053] The pressurizing assembly 4 is used to drive the second clamping plate 22 to move towards the template, increasing the pressure of the second clamping plate 22 on the template. The pressurizing assembly 4 includes a second eccentric handle 42. The second eccentric handle 42 is rotatably installed on the front and rear sides of the bottom of the second clamping plate 22 through a second connecting shaft 41. The eccentric wheel of the second eccentric handle 42 abuts against the back of the movable chuck 24, and a limit bolt 43 is provided at the head of the second eccentric handle 42.

[0054] Rotating the second eccentric handle 42 downward can squeeze the movable chuck 24 towards the fixed chuck 13, thereby increasing the pressure of the movable chuck 24 on the template. After the second eccentric handle 42 rotates to be parallel to the movable chuck 24, tightening the limit bolt 43 can limit the rotation of the second eccentric handle 42, thereby maintaining the pressure on the template.

[0055] In this embodiment, when an operator uses this device, the fixed chuck 13 is abutted against the template, and the sliding sleeve 21 is pushed towards the template.

[0056] When an external force to the left is applied to the sliding sleeve 21, the sliding sleeve 21 will slide towards the fixed chuck 13. As a result, the ratchet plate 31 will slide upward under the extrusion of the inclined surface of the tooth groove 14, and then move downward under the elastic force of the compression spring 34 to maintain contact with the tooth groove 14. At the same time, the second clamping plate 22 and the movable chuck 24 will move along with the sliding sleeve 21, thereby quickly shortening the distance between the fixed chuck 13 and the movable chuck 24 until the movable chuck 24 abuts against the template, realizing the quick clamping of the template.

[0057] Rotating the second eccentric handle 42 downward can squeeze the movable chuck 24 towards the fixed chuck 13, thereby increasing the pressure of the movable chuck 24 on the template. After the second eccentric handle 42 rotates to be parallel to the movable chuck 24, tightening the limit bolt 43 can limit the rotation of the second eccentric handle 42, thereby maintaining the pressure on the template.

[0058] After pouring is completed, wait for the concrete to solidify.

[0059] Loosen the limit bolt 43 and rotate the second eccentric handle 42 upward to release the pressure of the movable chuck 24 on the template.

[0060] Rotate the eccentric handle 35 upward to drive the adjusting shaft 33 to move outward, thereby driving the ratchet plate 31 away from the tooth groove 14, realizing the separation of the ratchet plate 31 and the tooth groove 14, applying a force to the right to the sliding sleeve 21, and driving the sliding sleeve 21 to slide to the right along the fixed strip 11 to realize the quick release of the template.

[0061] The above has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only the preferred examples of the present utility model and are not used to limit the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
