Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to a retractable clamp and a casting molding component. Background Art
[0002] In the field of construction, reinforced concrete structures require formwork to be secured during concrete pouring, as pouring concrete creates lateral pressure on the formwork, causing deformation. Traditional reinforcement methods use a combination of tie rods and butterfly buckles to balance the lateral pressure on the formwork during concrete pouring.
[0003] The casting of reinforced concrete beams typically utilizes traditional side formwork reinforcement. However, the use of tie rods for formwork reinforcement creates holes after the formwork is removed, requiring secondary sealing. This involves working at height and using an operating platform, which introduces inconvenience. Furthermore, during the concrete pour, inserted vibrators are used to ensure a dense concrete placement. These vibrators can easily contact the tie rods, impacting the beam reinforcement system and, consequently, the visual quality of the post-cast beam, posing the risk of secondary repairs. Utility Model Content
[0004] The purpose of the present utility model is to provide a retractable clamp and casting forming assembly to address the above-mentioned deficiencies, which solves the problem that in the prior art, when pouring reinforced concrete beams, after the formwork is reinforced by tension screws, holes will be formed after the formwork is removed, and the holes need to be sealed a second time, which involves high-altitude operations and the use of operating platforms, bringing inconvenience to construction; at the same time, during the vibration process, the tension screws are easily touched, which affects the reinforcement system of the beam and further affects the visual quality of the beam after casting.
[0005] The utility model is realized by the following scheme:
[0006] A retractable clamp includes at least but not limited to a first support member, a second support member and an adjusting member, wherein the first support member and the second support member are provided with a connecting groove for the adjusting member to pass through, and the adjusting member passes through the connecting groove to connect the first support member and the second support member into one body, and the connecting groove is provided on the ends of the first support member and the second support member away from the top plate, and a supporting space for a concrete beam mold can be formed between the first support member and the second support member.
[0007] Based on the above-mentioned retractable clamp structure, the first support member includes a first clamp vertical support, a first clamp cross piece and a first clamp diagonal support; the first clamp vertical support is arranged at the end of the first clamp cross piece, the first clamp vertical support and the first clamp cross piece are arranged at 90 degrees, the first clamp diagonal support is arranged obliquely between the first clamp vertical support and the first clamp cross piece, the connecting groove is arranged in the first clamp cross piece, and the connecting groove runs through the entire first clamp cross piece.
[0008] Based on the structure of the retractable clamp described above, a support gasket for limiting the adjusting member is provided on the end surface of the first clamp crosspiece away from the first clamp vertical support.
[0009] Based on the above-mentioned retractable clamp structure, the second support member includes a second clamp vertical support, a second clamp cross piece and a second clamp diagonal support; the second clamp vertical support is arranged at the end of the second clamp cross piece, the second clamp vertical support and the second clamp cross piece are arranged at 90 degrees, the second clamp diagonal support is obliquely arranged between the second clamp vertical support and the second clamp cross piece, the connecting groove is arranged in the second clamp cross piece, and the connecting groove runs through the entire second clamp cross piece.
[0010] Based on the structure of the retractable clamp described above, a support gasket for limiting the adjusting member is provided on the end surface of the second clamp crosspiece away from the second clamp vertical support.
[0011] Based on the above-mentioned retractable clamp structure, the adjusting member includes an adjusting screw, an adjusting nut and a locking nut; the adjusting screw passes through the connecting groove of the first support member and the second support member, and external threads are provided in at least part of the area of the two ends of the adjusting screw, and the adjusting nut and the locking nut are respectively sleeved on the two ends of the adjusting screw.
[0012] Based on the above-mentioned retractable clamp structure, a first auxiliary rod is arranged between the first clamp vertical support and the first clamp diagonal support, and the first auxiliary rod is arranged parallel to the first clamp cross piece. A second auxiliary rod is arranged between the second clamp vertical support and the second clamp diagonal support, and the second auxiliary rod is arranged parallel to the second clamp cross piece.
[0013] Based on the above-mentioned retractable clamp structure, a third auxiliary rod is arranged between the first clamp diagonal support and the first clamp cross piece, and the third auxiliary rod is arranged parallel to the first clamp vertical support. A fourth auxiliary rod is arranged between the second clamp diagonal support and the second clamp cross piece, and the fourth auxiliary rod is arranged parallel to the second clamp vertical support.
[0014] Based on the structure of the above-mentioned retractable clamp, the first support member and the second support member are both made of rectangular tubes.

[0018] 2. This solution can firmly clamp the concrete beam mold through multiple retractable clamps.

At the same time, it can also be adaptively adjusted according to the size of the formed beam. At the same time, different retractable clamp models can be selected according to the strength of the beam to be supported.
[0019] 3. The retractable clamp design of this solution can freely adjust the length of the cross bar according to actual construction needs, so as to adapt to the construction needs of beams of various widths, and can easily cope with them, while improving construction efficiency and quality: since the traditional tension screws are eliminated, the secondary sealing of the holes after the reinforced concrete beam is formed is eliminated, which not only ensures the convenience of construction operations, but also improves the quality and safety of construction.
[0020] 4. The main material of this solution is rectangular tube, which can be recycled or depreciated after use, greatly reducing the construction cost of the material, improving the turnover rate, and having higher economic benefits. Compared with the existing technology, this solution has better adaptability, higher construction efficiency and quality, and lower material and cost consumption, and has high practical value and broad application prospects.
