Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a formwork clamp for building construction. Background Technology

[0002] In the construction industry, formwork, as a crucial tool for concrete shaping, directly impacts the dimensional accuracy and appearance quality of concrete components through its securing effect. With the rapid development of the construction industry and increasingly stringent requirements for construction efficiency and project quality, formwork clamps, as key components ensuring the stability of formwork installation, are of paramount importance in terms of their performance.

[0003] Currently, the main problems with common construction formwork clamps on the market are as follows: Some clamps use simple bolt fastening methods. During construction, the lateral pressure and vibration generated by concrete pouring can easily cause the bolts to loosen, resulting in displacement and deformation of the formwork, which in turn affects the forming quality of the concrete components. Utility Model Content

[0004] To address the above problems, this utility model provides a building construction formwork clamp.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0006] A construction template clamp includes an installation plate on which a first clamping rod and a second clamping rod are mounted. The first clamping rod and the second clamping rod are adapted to each other in shape. A driving mechanism is provided on the installation plate. The driving mechanism connects the first clamping rod and the second clamping rod to drive the first clamping rod and the second clamping rod to come close together to clamp the workpiece.

[0007] Preferably, the drive mechanism includes a motor fixedly mounted on a mounting plate, and a transmission gear is fixedly mounted on the output end of the motor.

[0008] Preferably, a first incomplete gear and a second incomplete gear are rotatably mounted on the mounting plate, the first incomplete gear and the second incomplete gear meshing with each other, and the second incomplete gear meshing with a transmission gear.

[0009] Preferably, a first rotating rod is fixedly installed on the first incomplete gear, and a second rotating rod is fixedly installed on the second incomplete gear. The first incomplete gear, the second incomplete gear, the first clamping rod, and the second clamping rod are rotatably connected in a one-to-one correspondence.

[0010] Preferably, a first connecting rod is rotatably mounted on the first clamping rod, and a second connecting rod is rotatably mounted on the second clamping rod.

[0011] Preferably, the ends of the first clamping rod and the second clamping rod that are close to each other are provided with multiple strip grooves.

[0012] Preferably, the first incomplete gear, the second incomplete gear, and the transmission gear are located on the same plane.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The mounting plate is made of high-strength alloy steel with rust-proof treatment and features symmetrical mounting holes, allowing for secure installation on construction supports and other structures. This provides reliable support for the entire clamp and ensures stability and durability in complex construction environments. The first and second clamping rods adopt an arc-shaped design and are made of high-quality engineering plastic with an embedded metal frame. This design not only conforms to the template to increase the contact area but also adapts to different template shapes due to its flexibility. The staggered grooves at the close ends of the clamping rods effectively increase friction and prevent template slippage.

[0015] 2. The drive mechanism adopts a high-torque, low-noise DC motor, paired with involute tooth profile and hardened tooth surface transmission gears, as well as meshing and coplanar first and second incomplete gears, to ensure smooth and accurate transmission. With the help of an automatic lubrication device, friction and wear are reduced. The first and second rotating rods are rotatably connected to the mounting plate through deep groove ball bearings to reduce rotational resistance. The first and second connecting rods are rotatably connected to the clamping rods through pins and to the rotating rods through threads, which facilitates disassembly and maintenance.

[0023] Reference Figs. 1-3 A construction formwork clamp uses an mounting plate 1 as its basic load-bearing component. The mounting plate 1 is made of high-strength alloy steel with a rust-proof surface treatment to ensure stability and durability in complex construction environments. The mounting plate 1 has symmetrically distributed mounting holes, allowing it to be securely installed on construction supports or other fixed structures using bolts, providing reliable support for the entire clamp.

[0024] Mounting plate 1 is equipped with a first clamping rod 8 and a second clamping rod 10. The two rods are shaped to fit the template surface, employing an arc design. This shape allows for better contact with the template surface, increasing the contact area and thus improving clamping stability. The first clamping rod 8 and the second clamping rod 10 are made of high-quality engineering plastic with an embedded metal frame. This ensures both flexibility to adapt to different template surface shapes and sufficient strength to prevent deformation and damage. Multiple slots are provided at the ends of both rods that are close to each other. These slots are arranged in a staggered pattern to effectively increase friction with the template and prevent slippage during construction.

[0025] The drive mechanism is the core component of this fixture to achieve its clamping function. The drive mechanism includes a motor 6 fixedly mounted on the mounting plate 1. The motor 6 is a high-torque, low-noise DC motor, and its output end is fixedly mounted with a transmission gear 7 via a high-precision coupling. The transmission gear 7 adopts an involute tooth profile, and the tooth surface is hardened to enhance wear resistance and transmission efficiency.

[0026] A first incomplete gear 3 and a second incomplete gear 5 are rotatably mounted on the mounting plate 1, meshing with each other. The second incomplete gear meshes with the transmission gear 7. The first incomplete gear 3, the second incomplete gear 5, and the transmission gear 7 are all on the same plane, ensuring smooth and accurate transmission. To reduce friction and wear during gear transmission, an automatic lubrication device is installed at the gear meshing points, providing lubricating oil to the gears at regular intervals and in measured quantities.

[0027] A first rotating rod 2 is fixedly mounted on the first incomplete gear 3, and a second rotating rod 4 is fixedly mounted on the second incomplete gear 5. Both the first rotating rod 2 and the second rotating rod 4 are rotatably connected to the mounting plate 1 via deep groove ball bearings to reduce rotational resistance. The first incomplete gear 3 and the second incomplete gear 5 are rotatably connected to the first clamping rod 8 and the second clamping rod 10 in a one-to-one correspondence. Specifically, a first connecting rod 9 is rotatably mounted on the first clamping rod 8, and a second connecting rod 11 is rotatably mounted on the second clamping rod 10. One end of the first connecting rod 9 and the second connecting rod 11 are rotatably connected to the first clamping rod 8 and the second clamping rod 10 respectively via pins, while the other end is connected to the first rotating rod 2 and the second rotating rod 4 via threads, facilitating disassembly and maintenance.

[0028] When motor 6 starts, its output drives transmission gear 7 to rotate, which in turn drives second incomplete gear 5 to rotate. Since first incomplete gear 3 and second incomplete gear 5 mesh with each other, first incomplete gear 3 also rotates. The rotation of first incomplete gear 3 and second incomplete gear 5 is transmitted through first rotating rod 2 and second rotating rod 4, and then through first connecting rod 9 and second connecting rod 11, causing first clamping rod 8 and second clamping rod 10 to come close together, thereby clamping the workpiece. By controlling the rotation direction and speed of motor 6, precise control of the opening and closing degree of first clamping rod 8 and second clamping rod 10 can be achieved, meeting the clamping requirements of templates of different sizes.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
