Description

Technical Field

[0001] This utility model relates to an adjustable formwork clamp for preventing grout leakage during concrete pouring, and belongs to the field of civil engineering construction technology. Background Technology

[0002] Formwork is a temporary support structure, manufactured according to design requirements, to shape concrete structures and components according to specified positions and geometric dimensions, maintain their correct position, and bear the self-weight of the formwork and external loads acting on it. The purpose of formwork engineering is to ensure the quality and safety of concrete projects, accelerate construction progress, and reduce project costs. During the support process, formwork typically requires reinforcement using clamps.

[0003] Traditional formwork reinforcement clamps for construction use screws and steel pipes to drill holes in the formwork, and then pull the screws together to reinforce the formwork. Because holes need to be drilled in the formwork, grout leakage is likely to occur. In addition, point-to-point reinforcement is prone to formwork bulging. Therefore, we have proposed an adjustable formwork clamp for concrete pouring to prevent grout leakage and solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an adjustable formwork clamp for preventing grout leakage during concrete pouring, so as to solve the existing problems.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an adjustable formwork clamp for concrete pouring to prevent grout leakage, comprising a formwork body and a clamp assembly for reinforcing the formwork body, the clamp assembly comprising a clamp plate whose side wall abuts against the formwork body and an adjustment pin installed on the clamp plate; One end of the card plate is provided with a bending limiting part, and the end of the card plate away from the bending limiting part is provided with a first through hole and a second through hole arranged in a straight line structure. Multiple first through holes and second through holes are provided at equal intervals. The side wall of the card plate is integrally formed with reinforcing ribs. The adjusting pin is arranged in an isosceles triangle structure, and the adjusting pin is inserted into the inner side of the first through hole and fits tightly against the side wall of the bending limiting part. The top of the adjusting pin is integrally formed with a thickened part.

[0006] Furthermore, the adjusting pin has a round hole, and a cylindrical rod that passes through the adjusting pin is inserted into the round hole; The outer diameter of the cylindrical rod is matched with the inner diameter of the circular hole, and the cylindrical rod is a solid structure.

[0007] Furthermore, there are four card plates, and the four card plates are connected end to end by a bending limiting part.

[0008] Furthermore, the spacing of the bending limiting part is adapted to the thickness of the card plate.

[0009] Furthermore, the end of the first through hole corresponds to the middle section of the second through hole, and the end of the second through hole corresponds to the middle section of the first through hole.

[0010] Furthermore, the length of the top of the adjusting pin is greater than the length of the first through hole and the second through hole.

[0011] Furthermore, the card plate, adjusting pin, and cylindrical rod are all made of aluminum alloy.

[0012] The beneficial effects of the utility model are: (1) After connecting the four card plates end to end through the bending limiting part and wrapping them around the template body, the card plates can be slidably adjusted according to the different sizes of the template body by using the bending limiting part. By placing the adjusting pin in the first or second through hole, and then using a hammer to strike the thickened part, the bending limiting part is squeezed during the downward movement of the adjusting pin, so that the card plate can be finely adjusted, thereby making the card plate fit tightly with the template body, replacing the screw and steel pipe, eliminating the need for drilling the template and increasing the number of turnovers. There are no perforations and no grout leakage. The quality of the project is improved by increasing the reinforcement section without bulging the template.

[0013] (2) The reinforcement system is simple and easy to disassemble, which increases the formwork support speed by 2-3 times and saves labor costs.

[0014] (3) It can be reused multiple times, with minimal damage to the template, thus increasing the number of times the template can be reused. Attached Figure Description

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] like Figure 1-4The adjustable formwork clamp for concrete pouring to prevent grout leakage includes a formwork body 1 and a clamp assembly for reinforcing the formwork body 1. The clamp assembly includes a clamp plate 2 whose side wall abuts against the formwork body 1 and an adjusting pin 7 installed on the clamp plate 2. One end of the card plate 2 is provided with a bending limiting part 3. The end of the card plate 2 away from the bending limiting part 3 is provided with a first through hole 4 and a second through hole 5 arranged in a straight line structure. Multiple first through holes 4 and second through holes 5 are provided at equal intervals. The side wall of the card plate 2 is integrally formed with reinforcing ribs 6. The adjusting pin 7 is arranged in an isosceles triangle structure, and is inserted into the inner side of the first through hole 4 and tightly fitted to the side wall of the bending limiting part 3. The top of the adjusting pin 7 has an integrally formed thickened part 8. When using this concrete pouring anti-leakage adjustable formwork clamp, during the support of the formwork body 1, after the four clamping plates 2 are connected end to end through the bending limiting part 3 and wrapped around the formwork body 1, the clamping plates 2 can be slidably adjusted according to different sizes of the formwork body 1 using the bending limiting part 3. An adjusting pin 7 is placed in either the first through hole 4 or the second through hole 5 (depending on which one is closer to the bending limiting part 3). Then, the thickened part 8 is struck with a hammer, causing the adjusting pin 7 to move downward and squeeze the bending limiting part 3. This allows for fine adjustment of the clamping plate 2, making the clamping plate 2 fit tightly against the template body 1, replacing screws and steel pipes. The template is free from drilling and has increased turnover times. There are no perforations or grout leakage. The increased reinforcement section prevents bulging and improves the quality of the project. The reinforcement system is simple, easy to disassemble, increases formwork erection speed by 2-3 times, and saves labor costs; It can be reused multiple times with minimal damage to the template, thus increasing the number of times the template can be reused.

[0019] like Figure 4 As shown, the adjusting pin 7 has a round hole 9, and a cylindrical rod that passes through the adjusting pin 7 is inserted into the round hole 9. The outer diameter of the cylindrical rod is matched with the inner diameter of the circular hole 9, and the cylindrical rod is a solid structure. When disassembling the adjusting pin 7, the cylindrical rod is inserted into the inner side of the circular hole 9, and then the cylindrical rod is struck upward with a hammer to facilitate the disassembly of the adjusting pin 7.

[0020] like Figure 2 As shown, there are four card plates 2, and the four card plates 2 are connected end to end by bending limiting parts 3. The spacing of the bending limiting parts 3 is adapted to the thickness of the card plates 2. The end portion of the clamping plate 2 engages with the gap of the bending limiting part 3, which not only facilitates the connection between the end portions of the clamping plates 2, but also ensures the stability of the connection between the clamping plates 2.

[0021] like Figure 3As shown, the end of the first through hole 4 corresponds to the middle section of the second through hole 5, and the end of the second through hole 5 corresponds to the middle section of the first through hole 4. By staggering the first through hole 4 and the second through hole 5, the distance between the first through hole 4 and the second through hole 5 and the bending limit part 3 can be reduced, thereby improving the adjustment accuracy by adjusting the pin 7.

[0022] like Figure 3 , Figure 4 As shown, the length of the top of the adjusting pin 7 is greater than the lengths of the first through hole 4 and the second through hole 5; Prevent the adjusting pin 7 from passing through the first through hole 4 or the second through hole 5.

[0023] The card plate 2, adjusting pin 7, and cylindrical rod are all made of aluminum alloy, which has the advantages of being lightweight, high-strength, and not easily deformed.

[0024] In use: During the support of the template body 1, after the four clamping plates 2 are connected end to end through the bending limiting part 3 and wrapped around the template body 1 once, the clamping plates 2 can be slidably adjusted according to the different sizes of the template body 1 by using the bending limiting part 3. By placing the adjusting pin 7 in the first through hole 4 or the second through hole 5 (depending on which of the first through hole 4 or the second through hole 5 is closer to the bending limiting part 3), and then using a hammer to strike the thickened part 8, the adjusting pin 7 will be pressed against the bending limiting part 3 as it moves down, thereby fine-tuning the clamping plate 2 and making the clamping plate 2 fit tightly with the template body 1 to achieve reinforcement.
