Description

Technical Field

[0001] The present application relates to the technical field of formwork clamps, and in particular to an adjustable clamp for the top pressure of a composite thermal insulation formwork exterior wall. Background Art

[0002] A counterhedge is a structure in a building that extends perpendicular to the roof, preventing cracks between the horizontal roof and the vertical structure. The counterhedge allows the roof's waterproofing layer to extend onto the vertical structure, preventing leaks. To prevent gaps between the counterhedge and the roof, the counterhedge is cast simultaneously with the roof during construction. Before pouring, the counterhedge formwork is assembled to create a counterhedge casting cavity that matches the shape of the counterhedge. Concrete is then pumped into the cavity, and once the concrete solidifies, the counterhedge is formed.

[0003] For projects where composite insulation formwork is used for exterior wall insulation, during the pouring of the exterior wall counterslope and capping concrete, integrated insulation composite formwork must be installed outside the concrete to ensure the integrity of the insulation system. Traditionally, exterior wall insulation was installed after the exterior wall concrete and masonry were completed. The counterslope and capping could be poured along with the structure, making formwork support and fixing relatively simple.

[0004] With respect to the above-mentioned related technologies, the inventors believe that in the case where the exterior wall insulation is a composite insulation formwork constructed along with the main body, different formworks need to be replaced according to the different heights of the anti-slopes, which has the defect of not being reusable. Summary of the Invention

[0005] In order to enable the reuse of the clamp, the present application provides an adjustable clamp for the external wall top of a composite thermal insulation formwork.

[0006] The present application provides an adjustable clamp for the external wall top of a composite thermal insulation formwork, which adopts the following technical solutions:

[0007] The cam is secured to the first and second clamping rods and has a spring loaded cam which allows the cam to slide relative to the first clamping rod and the second clamping rod to move relative to the first clamping rod.

[0008] By adopting this technical solution, workers use a trigger lever to squeeze different numbers of adjustment rods, then secure the trigger lever to the first clamping rod, thereby maintaining the stability of the adjustment plate. Through the adjustment assembly, workers move the first and second clamping rods toward each other, causing the contact plate and second clamping rods to press against the exterior wall concrete. During pouring, workers pour concrete slurry between the adjustment plate and the composite insulation formwork. With this structure, different numbers of adjustment plates can be assembled to form different formwork widths, thereby meeting various specifications of anti-slope heights, thus achieving the effect of reusable clamps.

[0010] By adopting the above technical solution, the operator inserts the appropriate limit block into the through slot according to the required number of adjustment plates, inserts the trigger rod into the cavity and abuts the limit block. During the movement of the trigger rod, the first inclined surface causes the adjustment rod to press against the adjustment plates, so that the extended adjustment plates form a template. This structure makes it easy for the operator to determine the insertion length of the trigger rod.

[0011] Optionally, the limit assembly includes a card block and a second spring, a side wall of the trigger rod is provided with a receiving groove, the card block is arranged in the receiving groove, the card block is slidably connected to the trigger rod in the horizontal direction, the second spring is provided in the receiving groove, both ends of the second spring are fixedly connected to the card block and the trigger rod respectively, the side wall of the limit block facing the trigger rod is provided with an installation groove that is adapted to be plugged into the trigger rod, the inner wall of the limit block at the installation groove is provided with a card groove that is adapted to be plugged into the card block, and the inner bottom wall of the limit block at the card groove is provided with an avoidance groove for the card block to pass through, the avoidance groove is connected to the installation groove, and the avoidance groove runs through the bottom wall of the limit block.

[0012] By adopting the above technical solution, the clamping block is retracted into the storage slot, and then the trigger rod is inserted into the installation slot. When the clamping slot and the storage slot are aligned, the second spring releases its elastic force to push the clamping block into the clamping slot. The clamping connection between the clamping block and the clamping slot prevents the trigger rod from easily falling out of the cavity.

[0016] By adopting the above technical solution, when the staff rotates the two bidirectional screws at the same time, the second sleeve and the third sleeve respectively make the first clamping rod and the second clamping rod less likely to rotate with the bidirectional screws, thereby causing the first clamping rod and the second clamping rod to move toward each other or away from each other, thereby achieving the effect of adjusting the distance between the first clamping rod and the second clamping rod.

[0017] Optionally, a transmission roller is provided on one side of the first clamping rod in the vertical direction, a first bevel gear is fixed to one end of the bidirectional screw close to the transmission roller, and a second bevel gear is fixed to both ends of the transmission roller.

[0044] The staff pulls out the insertion rod 751 from the first hole 744, at which time the third spring 752 is stretched, and then pushes the limit block 74 into the through groove 73. At this time, the second hole 745 is aligned with the insertion rod 751, and then releases the insertion rod 751. The third spring 752 releases the elastic force to insert the insertion rod 751 into the second hole 745.

[0045] refer to Figure 4 The trigger rod 5 is slidably connected to the cavity 71. The diameter of the trigger rod 5 is smaller than the diameter of the cavity 71.

After being squeezed, the adjusting rod 12 slides in the horizontal direction. The sliding of the adjusting rod 12 drives the adjusting plate 121 to move. The movement of the adjusting plate 121 stretches the first spring 13. When the trigger rod 5 is pulled out of the cavity 71, the first spring 13 releases the elastic force to drive the adjusting plate 121 to reset.
