Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, and in particular to a temporary reinforcement tool for a reusable main steel pipe. Background Technology
[0002] In traditional wooden formwork reinforcement construction, double steel pipes are often used as the main ribs for formwork reinforcement. When reinforcing the main ribs of walls and columns, tie bolts are used to penetrate the formwork on both sides and pass between the two main ribs. After tightening the nuts of the tie bolts, the top support can be pressed against the outside of the double steel pipes, which can reinforce the main ribs and formwork.
[0003] During construction, the double steel pipes (main ribs) are prone to falling because they are not fixed. Construction workers need to support the double steel pipes to facilitate the installation and tightening of tie bolts and nuts. Manually supporting the main ribs is inconvenient, time-consuming, and detrimental to cost savings. Therefore, a reusable temporary reinforcement tool for the main ribs is needed to solve the problem of inconvenient temporary fixing of the main ribs in existing technologies. Summary of the Invention
[0004] The purpose of this utility model is to provide a reusable temporary reinforcement tool for main rib steel pipes, which can solve the problem of inconvenient operation for temporary fixing of main rib steel pipes in the prior art.
[0005] This utility model is implemented as follows:
[0006] A temporary reinforcement tool for reusable main rib steel pipes includes a first retaining ring, a second retaining ring, an operating handle, and a connecting plate. The first retaining ring is located at the upper end of the connecting plate and has an arc-shaped structure, allowing it to fit snugly onto the upper main rib steel pipe. The second retaining ring is located at the lower end of the connecting plate and has a flat plate structure, allowing it to support the bottom of the lower main rib steel pipe. The operating handle is located in the middle of the side of the connecting plate away from the main rib steel pipe.
[0007] The inner diameter of the first retaining ring matches the outer diameter of the main rib steel pipe, and the first retaining ring has a semi-circular structure.
[0008] The second retaining ring is perpendicularly connected to the connecting plate in an L-shaped structure.
[0009] The second retaining ring is tangent to the lower end of the main rib steel pipe, and the connecting plate is tangent to the side of the two main rib steel pipes away from the wooden template.
[0010] The first retaining ring, the second retaining ring, the operating handle, and the connecting plate are an integral structure.
[0011] The operating handle is in the shape of an isosceles triangle, with the apex of the isosceles triangle connected to the connecting plate.
[0012] Compared with the prior art, this utility model has the following advantages:
[0013] 1. This utility model has a first retaining ring and a second retaining ring. The semi-circular first retaining ring can be matched and locked on the upper part of the main rib steel pipe located above, and the flat second retaining ring can support the bottom of the main rib steel pipe located below, thereby ensuring the relative fixation of the two main rib steel pipes. It has a good temporary reinforcement effect, is easy to disassemble and assemble, and is not easy to fall off. Compared with the traditional manual hand support of the main rib steel pipe, it is more convenient and simple.
[0014] 2. Because this utility model is equipped with an operating handle, after the first and second retaining rings are fitted onto the two main steel pipes, the construction personnel can hold the operating handle to ensure the stability and reliability of the temporary reinforcement of the two main steel pipes, making the operation simpler and less labor-intensive.
[0015] 3. This utility model can be adapted to the main rib steel pipe, is easy to source and manufacture, has a low cost, and the interlocking method makes disassembly and assembly convenient and efficient, which helps to improve the efficiency of the main rib reinforcement operation of wooden formwork and has a high turnover rate. Attached Figure Description
[0016] Figure 1 This is an installation diagram of the temporary reinforcement tool for the reusable main steel pipe of this utility model.
[0017] In the diagram, 1 is the first retaining ring, 2 is the second retaining ring, 3 is the operating handle, 4 is the connecting plate, 5 is the main rib steel pipe, and 6 is the tie bolt. Detailed Implementation
[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0019] Please see the appendix Figure 1 A temporary reinforcement tool for reusable main rib steel pipes includes a first retaining ring 1, a second retaining ring 2, an operating handle 3, and a connecting plate 4. The first retaining ring 1 is located at the upper end of the connecting plate 4 and has an arc-shaped structure, allowing it to fit onto the upper main rib steel pipe 5. The second retaining ring 2 is located at the lower end of the connecting plate 4 and has a flat plate structure, allowing it to support the bottom of the lower main rib steel pipe 5. The operating handle 3 is located in the middle of the side of the connecting plate 4 away from the main rib steel pipe 5.
[0020] The dimensions of the arc-shaped structure of the first retaining ring 1 and the length of the second retaining ring 2 can be determined according to the dimensions of the main rib steel pipe 5. This ensures that the first retaining ring 1 can be securely fitted onto the upper main rib steel pipe 5 through its arc-shaped structure, preventing it from easily falling off. The second retaining ring 2 can support the lower main rib steel pipe 5, thereby relatively fixing the two main rib steel pipes 5. This provides a good temporary fixation effect, facilitating the subsequent installation and tightening of the tie bolts 6 and their nuts. After the entire tool is fitted onto the two main rib steel pipes 5, the construction worker can hold the operating handle 3 to ensure the stability and positioning accuracy of the temporary reinforcement of the two main rib steel pipes 5. Compared with the traditional manual support reinforcement method, this operation is simpler, more convenient, and less labor-intensive.
[0021] Preferably, the first retaining ring 1, the second retaining ring 2, and the connecting plate 4 can be made of flat iron, and the operating handle 3 can be made of steel bars. Flat iron and steel bars are common materials on the construction site, which are easy to obtain and manufacture. They can also be made from waste flat iron and steel bar materials, which are green and environmentally friendly, have low cost, are easy to manufacture, and have good versatility and adaptability.
[0022] The inner diameter of the first retaining ring 1 matches the outer diameter of the main rib steel pipe 5, and the first retaining ring 1 has a semi-circular structure.
[0023] The shape of the first retaining ring 1 can be bent and made according to the outer diameter of the main rib steel pipe 5 at the construction site. The semi-circular structure ensures that the first retaining ring 1 and the main rib steel pipe 5 have sufficient contact area, thereby ensuring that the entire tool will not detach from the main rib steel pipe 5.
[0024] The second retaining ring 2 is vertically connected to the connecting plate 4 in an L-shaped structure, ensuring that the second retaining ring 2 can stably support the main rib steel pipe 5 located below.
[0025] The first retaining ring 1 of the semi-circular structure applies a downward force to the main rib steel pipe 5, and the second retaining ring 2 of the flat plate structure applies an upward force to the main rib steel pipe 5. The stability and reliability of the temporary reinforcement of the two main rib steel pipes 5 are ensured by the upper pressure and lower push.
[0026] The second retaining ring 2 is tangent to the lower end of the main rib steel pipe 5, and the connecting plate 4 is tangent to the side of the two main rib steel pipes 5 away from the wooden template.
[0027] The second retaining ring 2 and the connecting plate 4 limit the main rib steel pipe 5 from the bottom and the outside to ensure that the main rib steel pipe 5 fits against the outer surface of the wooden formwork, which is conducive to the accurate installation of the tie bolts 6 and the effective reinforcement of the wooden formwork by the main rib.
[0028] The first retaining ring 1, the second retaining ring 2, the operating handle 3, and the connecting plate 4 are an integral structure with high structural strength, making them resistant to deformation and breakage.
[0029] The operating handle 3 is in the shape of an isosceles triangle, and the apex of the isosceles triangle is connected to the connecting plate 4.
[0030] The isosceles triangular structure of the operating handle 3 makes it easier to grip, with a large contact area with the hand, high grip stability, and even force distribution, making it less prone to deformation and damage.
[0031] Preferably, the first retaining ring 1, the second retaining ring 2, and the connecting plate 4 are all made of flat iron with a thickness of 2mm. The width of the flat iron can be adapted to the actual usage requirements. The upper end of the flat iron is curved to form the first retaining ring 1, with an arc length of 848mm. The lower end of the flat iron is bent at a right angle to form the second retaining ring 2, with a length of 700mm. The middle part of the flat iron serves as the connecting plate 4. The operating handle 3 can be made of HRB400 steel bar with a diameter of 8mm and a length of 1000mm. The steel bar is bent to form an isosceles triangle structure and welded to the middle part of the connecting plate 4.
[0032] Please see the appendix Figure 1 The method of use and working principle of this utility model are as follows:
[0033] The tool of this utility model is fitted onto the ends of the two main rib steel pipes 5 along the axial direction of the main rib steel pipe 5, so that the first retaining ring 1 locks the main rib steel pipe 5 located above. The arc-shaped first retaining ring 1 can match and fit against the upper arc surface of the main rib steel pipe 5, and the second retaining ring 2 supports the main rib steel pipe 5 located below. The second retaining ring 2 is tangential to the lower end of the main rib steel pipe 5.
[0034] By holding the operating handle 3, the two main steel pipes 5 can be temporarily fixed, making operation convenient and labor-saving. After the two main steel pipes 5 are temporarily fixed, the tie bolts 6 and their nuts can be tightened and installed (the tie bolts 6 are located on the inside of the tool, ensuring that the tool temporarily reinforces the two main steel pipes 5 without affecting the tool's removal and disassembly). After the tie bolts 6 are installed, the tool of this utility model can be pulled out from both sides along the axial direction of the main steel pipes 5 for reuse.
[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model.
