DETAILED DESCRIPTION

[0021] The utility model will be further explained in connection with the drawings and specific embodiments.

[0022] Please refer to the attached Figure 1 to the attached Figure 3 A kind of concrete formwork clamp, including bottom box 1, telescopic drive assembly, first moving plate 4, second moving plate 5, moving block 9, first clamping plate 10, second clamping plate 11, friction plate 12 and damping assembly;First moving plate 4 one end and the one end of second moving plate 5 are movably penetrated by telescopic drive assembly and set on bottom box 1, the other end of first moving plate 4 and the other end of second moving plate 5 extend in the direction away from bottom box 1;The other end of first moving plate 4 and the other end of second moving plate 5 are vertically fixedly connected with moving block 9, first clamping plate 10 and second clamping plate 11 are connected on two moving blocks 9 respectively, and first clamping plate 10 and second clamping plate 11 are parallelly arranged, so that first clamping plate 10 and second clamping plate 11 can be located respectively on the outside of the formwork on the two sides of component;First clamping plate 10 and second clamping plate 11 are provided with friction plate 12 by damping assembly, so that first clamping plate 10 and second clamping plate 11 are attached to the outer wall of the formwork on the two sides of component by friction plate 12.

[0023] Telescopic drive assembly drives first moving plate 4 and second moving plate 5 to move synchronously, so that first clamping plate 10 and second clamping plate 11 make the movement of approaching or moving away each other on the outside of the formwork on the two sides of component, and realize the stable clamping or release of the formwork on the two sides of component. Telescopic drive assembly can fix the distance between first clamping plate 10 and second clamping plate 11 to avoid clamping failure.

[0024] Preferably, friction plate 12 can be made of rubber material, which can increase the stability of first clamping plate 10 and second clamping plate 11 when attaching to the formwork on the two sides of component, improve the clamping effect, and will not slip. Damping assembly can buffer the stress of friction plate 12, slow down the vibration influence, further ensure the clamping reliability of first clamping plate 10 and second clamping plate 11 to the formwork on the two sides of component, and will not affect the clamping stability due to the vibration force generated by concrete pouring and vibrating during concrete pouring process.

[0025] Please see the attached Figure 3 , the telescopic drive assembly comprises motor 2, gear 3 and gear block 6; motor 2 is installed on the bottom box 1, the output shaft of motor 2 is inserted in the bottom box 1 and coaxially connected with gear 3; first moving plate 4 and second moving plate 5 are both provided with a plurality of gear blocks 6 at equal intervals, forming a rack matched with gear 3; first moving plate 4 and second moving plate 5 are tangent to the bottom and top of gear 3 respectively, so that first moving plate 4 and second moving plate 5 are connected to the bottom and top of gear 3 through rack engagement respectively; the end of first moving plate 4 and second moving plate 5 away from the bottom box 1 is connected with moving block 9.

[0026] Preferably, motor 2 can adopt bidirectional rotation motor in the prior art, which can drive gear 3 to rotate clockwise or counterclockwise, so as to drive first moving plate 4 and second moving plate 5 through the rack formed by gear block 6. First moving plate 4 and second moving plate 5 are tangent to the bottom and top of gear 3, which can make first moving plate 4 and second moving plate 5 move away from each other or move close to each other synchronously during the clockwise or counterclockwise rotation of gear 3, so as to realize the synchronous movement of first clamping plate 10 and second clamping plate 11 away from each other or close to each other.

[0027] Preferably, the output shaft of motor 2 can be coaxially connected with gear 3 by spline, shaft coupling or the like, so as to ensure that gear 3 remains stationary after motor 2 stops, thereby preventing first moving plate 4 and second moving plate 5 from moving, and further ensuring that first clamping plate 10 and second clamping plate 11 can stably and reliably clamp the templates on both sides of the component, without clamping failure under external force, thereby improving the clamping effect.

[0028] Please see the attached Figure 1 to the attached Figure 3 , the two side surfaces of the bottom box 1 are respectively fixedly connected with first stabilizing plate 7 and second stabilizing plate 8; first stabilizing plate 7 is arranged above first moving plate 4 in parallel, and the end of first stabilizing plate 7 away from the bottom box 1 movably penetrates moving block 9 on first moving plate 4; second stabilizing plate 8 is arranged below second moving plate 5 in parallel, and the end of second stabilizing plate 8 away from the bottom box 1 movably penetrates moving block 9 on second moving plate 5.

[0029] Preferably, the first stabilizing plate 7 and the second stabilizing plate 8 are rectangular strip-shaped structures. A through hole matching this cross-section is pre-drilled on the moving block 9, allowing the first stabilizing plate 7 to pass through the through hole of the moving block 9 on the first moving plate 4. This restricts the movement direction of the first moving plate 4, improving its stability and straightness, thereby ensuring the stable and reliable movement of the first clamping plate 10. Similarly, the second stabilizing plate 8 can pass through the through hole of the moving block 9 on the second moving plate 5, restricting its movement direction and improving its stability and straightness, thereby ensuring the stable and reliable movement of the second clamping plate 11.

[0030] Please see the appendix Figure 2 The first stabilizing plate 7 and the second moving plate 5 are coaxially arranged, and the first stabilizing plate 7 has a hollow structure. The end of the second moving plate 5 can penetrate the bottom box 1 and be inserted into the first stabilizing plate 7. The second stabilizing plate 8 and the first moving plate 4 are coaxially arranged, and the second stabilizing plate 8 has a hollow structure. The end of the first moving plate 4 can penetrate the bottom box 1 and be inserted into the second stabilizing plate 8.

[0031] The first stabilizing plate 7 and the second stabilizing plate 8 adopt a hollow structure, which facilitates the insertion of the second moving plate 5 into the first stabilizing plate 7 and the insertion of the first moving plate 4 into the second stabilizing plate 8. This can increase the movable range of the first moving plate 4 and the second moving plate 5, thereby making the spacing between the second clamping plate 11 and the first clamping plate 10 more adjustable. This can adapt to the spacing of the templates on both sides of components of different sizes, and has good versatility and adaptability.

[0032] Please see the appendix Figure 1 and attached Figure 3 The first stabilizing plate 7 and the second stabilizing plate 8 are both provided with a limiting plate 20 at the end away from the bottom box 1, and the moving block 9 is located between the bottom box 1 and the limiting plate 20.

[0033] The size of the limiting plate 20 is larger than the through hole on the moving block 9 for passing through the first stabilizing plate 7 and the second stabilizing plate 8. The limiting plate 20 located outside the moving block 9 is used to limit the movable range of the first stabilizing plate 7 and the second stabilizing plate 8 and to prevent the first stabilizing plate 7 and the second stabilizing plate 8 from coming off the moving block 9.

[0034] Please see the appendix Figure 4The damping assembly comprises connecting columns 13, a damping plate 14, damping springs 15 and a damping box 17. The connecting columns 13 are vertically fixed between the friction plate 12 and the damping plate 14, and the connecting columns 13 are movably penetrated through the first clamping plate 10 and the second clamping plate 11. The connecting columns 13 are parallel and spaced apart. The damping box 17 is open at one end and connected to the side of the first clamping plate 10 and the second clamping plate 11 away from the formwork. The damping plate 14 is slidably embedded in the damping box 17 through a slide rail and a slide block. A plurality of damping springs 15 are arranged between the side of the damping plate 14 away from the connecting columns 13 and the inner wall of the other end of the damping box 17, and the axial direction of the damping springs 15 is parallel to the axial direction of the connecting columns 13.

[0035] When the first clamping plate 10 and the second clamping plate 11 approach the formwork on both sides of the component, the friction plate 12 first contacts the outer wall of the formwork. When the first clamping plate 10 and the second clamping plate 11 continue to approach the formwork, the extrusion force between the friction plate 12 and the formwork acts on the damping plate 14 through the connecting columns 13, so that the slide blocks on both sides of the damping plate 14 move along the slide groove on the inner wall of the damping box 17, and the damping springs 15 are extruded. The connecting columns 13 and the damping springs 15 are arranged in a matrix or array, which ensures uniform overall stress and stable movement of the damping plate 14.

[0036] After being extruded, the damping springs 15 are compressed and store energy. The elastic force generated by the damping springs 15 acts on the friction plate 12, which can ensure that the first clamping plate 10 and the second clamping plate 11 stably clamp the formwork on both sides of the component and are not easy to loosen. In addition, the damping springs 15 can dissipate the vibration energy generated during the concrete pouring and vibrating process, thereby further ensuring the clamping stability of the formwork.

[0037] Preferably, the damping box 17 can adopt a rectangular box structure, and the friction plate 12 and the damping plate 14 can adopt a rectangular plate. The cross-sectional size of the rectangular box structure is consistent with the plate size of the friction plate 12, and the plate size of the damping plate 14 is slightly smaller than the cross-sectional size of the damping box 17.

[0038] Please refer to the accompanying drawings Figure 4 The other end of the damping box 17 is provided with a balance box 18, and the side of the damping plate 14 away from the connecting columns 13 is provided with a balance column 19. The balance column 19 is movably inserted into the balance box 18 to form a telescopic balance mechanism. A plurality of telescopic balance mechanisms are arranged at the corners of the damping box 17.

[0039] Preferably, the balance box 18 can adopt a hollow rectangular column structure, and the balance column 19 can adopt a rectangular column structure slightly smaller than the balance box 18, and the balance column 19 moves with the damping plate 14 and moves relative to the balance box 18. Through the arrangement of the four sets of telescopic balance mechanisms at the four corners of the damping box 17, the moving stability of the damping plate 14 can be improved, and the clamping effect of the first clamping plate 10 and the second clamping plate 11 can be ensured.

[0040] Please refer to the accompanying Figure 1 to the accompanying Figure 4 , the use method and working principle of the utility model are:

[0041] After the formwork on both sides of the component is erected, the whole clamp is moved to the component formwork, and the first clamping plate 10 and the second clamping plate 11 are located outside the component formwork. Start the motor 2, the motor 2 drives the gear 3 to rotate, the gear 3 is engaged with the first moving plate 4 at the bottom and the second moving plate 5 at the top through the rack formed by the tooth block 6, so that the first moving plate 4 and the second moving plate 5 drive the first clamping plate 10 and the second clamping plate 11 to move towards the component formwork respectively, until the first clamping plate 10 and the second clamping plate 11 are tightly pressed on the component formwork through the friction plate 12.

[0042] When the friction plate 12 contacts the component formwork, the force is transmitted to the damping plate 14 through the connecting column 13, so that the damping plate 14 moves along the sliding rail into the damping box 17 and extrudes the damping spring 15, and the damping spring 15 is compressed to store energy. At the same time, the balance column 19 is inserted into the balance box 18, and the elastic force of the damping spring 15 acts on the friction plate 12, so as to ensure the reliable clamping of the first clamping plate 10 and the second clamping plate 11 on the component formwork.

[0043] Turn off the motor 2, the gear 3 remains stationary and does not rotate any more, so that the first moving plate 4 and the second moving plate 5 do not move any more, thereby ensuring the stable and reliable clamping of the first clamping plate 10 and the second clamping plate 11 on the component formwork, and facilitating the concrete pouring of the component.

[0044] During the concrete pouring and vibrating process of the component, the vibration force is transmitted to the friction plate 12 through the formwork, and then the damping spring 15 dissipates energy, so as to ensure the reliable and stable clamping of the first clamping plate 10 and the second clamping plate 11 on the formwork during construction.

[0045] The above is only a preferred embodiment of the utility model, and is not used to limit the protection scope of the utility model, therefore, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the utility model should be included in the protection scope of the utility model.
