Description

Technical Field

[0001] The present invention relates to the technical field of building template clamps, and in particular to a convenient and precise building construction template clamp. Background Art

[0002] As a temporary supporting structure, building formwork is built according to design requirements to ensure that concrete structures and components are precisely formed in specified positions, strictly comply with established geometric dimensions, and maintain the correct position, while bearing its own weight and externally applied loads. Formwork clamps are special equipment used to fix formwork in construction. With the help of formwork clamps, the construction formwork can be effectively clamped and quickly shaped to ensure that the formwork always occupies the correct position during the construction process to meet construction needs. For example, a construction formwork clamp disclosed in application number CN202410472318.3.

[0003] At present, when fixing the square column formwork, a square column buckle clamp is generally used, that is, four mutually socketed clamps are used, and the limit pins are used to clamp the limit grooves at multiple different positions on the clamps to the corresponding limit grooves, so that the four clamps maintain a fixed shape to fix the formwork. This fixing method is cumbersome to operate and difficult to quickly achieve the fixation of the formwork. When using the clamp to clamp the formwork, it is usually clamped directly on the formwork for rigid fixation. However, during concrete pouring, the concrete will generate impact force on the formwork and squeeze the formwork outward. At the same time, the concrete needs to be vibrated during the pouring process. Therefore, when using rigid clamping, due to the lack of flexibility of the rigid clamping, it is unable to buffer and adapt to the impact force, squeezing force and dynamic changes of the concrete during pouring. This will make the formwork prone to cracks, deformation and even damage due to the excessive external force, reducing its reusability; it will also affect the fit between the formwork and the concrete, resulting in a decrease in the molding quality of the concrete component, and the occurrence of surface honeycombing, irregular edges and corners, etc. Summary of the Invention

[0013] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects: 1. The traditional square column buckle clamp uses four clamping plates with limit pins to clamp the limit slots to fix the template, which is cumbersome to operate. The convenient and precise clamp is designed with structures such as electromagnetic plates, rectangular permanent magnets, and threaded rods. First, the electromagnetic plate can be energized to separate the first threaded rod from the fixed shaft, and then the first threaded rod can be lifted. The second motor can be started to flip the second extrusion plate to expose the fixed port. After the clamp is put on the outside of the column template, the motor can be controlled to reverse to reset the second sliding block. Finally, the power is turned off to reset the rectangular permanent magnet to achieve the connection between the first threaded rod and the fixed shaft, thereby quickly completing the installation and disassembly of the clamp on the column template.

[0014] 2. Traditional fixtures use rigid fixation and cannot adapt to the dynamic changes in impact force, extrusion force, and vibration during concrete pouring. In the adaptive extrusion adjustment mechanism of the convenient and precise fixture, after the extrusion shell contacts the formwork, the reaction force of the formwork causes the extrusion shell to move inward, driving the connecting rod to squeeze the resistance plate, causing the push rod to squeeze the argon gas in the fixed sleeve. At the same time, the moving block drives the conductive sheet to slide on the resistance plate. The PLC controller detects the current change of the sliding rheostat to determine whether the formwork is clamped and controls the motor to stop. During the concrete pouring process, when the formwork is subjected to pressure changes, the current is adjusted by the sliding of the conductive sheet on the resistance plate. The PLC controller controls the vacuum pump to introduce argon gas between the fixed sleeve and the push rod. The elasticity and rigidity are adjusted according to the actual situation to adapt to the changes in concrete pressure, buffer the impact force, and prevent the displacement and deformation of the formwork.

[0015] 3. The convenient and precise clamps utilize an infrared transmitter and receiver to form an infrared rangefinder. Combined with the calculation module in the PLC controller, they can accurately measure the distance between clamps at different heights of the column formwork. Because the concrete pressure on the column formwork varies from top to bottom, the PLC controller controls the vacuum pump to introduce varying amounts of argon gas between the fixed sleeve and the push rod based on the measurement results. The amount of argon introduced decreases as the column formwork moves upwards, enabling precise adjustment of the clamp's extrusion force to better adapt to changes in pressure on the column formwork and ensure construction quality and safety.

[0029] The working principle of the application is as follows: After the first screw rod 318 is in the state of being rotated, the second motor 317 is started, and the third screw rod 318 is driven by the second motor 317 to rotate. At the same time, the second sliding groove 34 is used to limit the threaded block 320 and the second extrusion plate 36 to move in the direction close to the limit block 319 until the second sliding block 35 is separated from the second sliding groove. Since the threaded block 320 is hinged to the second extrusion plate 36, the second sliding block 35 and the second extrusion plate 36 will flip downward when there is no second sliding groove to support the second sliding block 35. At this time, a fixing hole will be exposed. The number of fixings of this clamp on the column template is set according to actual conditions, but it must be set at the top and bottom of the column template. Then, the clamp is put on the outside of the column formwork, and the U-shaped fixing frame is clamped around the column formwork through the above-mentioned fixing port. Then, the second motor 317 is controlled to reverse, and with the assistance of a worker, the second sliding block 35 is put back into the second sliding groove 34. Then, the first threaded rod 39 is reset, and the electromagnetic plate 314 is powered off. The elastic force of the plastic spring 315 is used to make the rectangular permanent magnet block 316 re-enter the rectangular groove 312, so that the fixed shaft 38 can drive the first threaded rod 39 and the second threaded rod 310 to rotate synchronously.

[0030] In the initial state, the amount of argon gas between the fixed sleeve 410 and the push rod 49 is half of the space between the two in the normal state. Then, the column template is squeezed and the first motor 37 and the second motor 317 are started. Then, the first motor 37 drives the fixed shaft 38, the first threaded rod 39, and the second threaded rod 310 to rotate synchronously. Then, the first sliding groove 31 limits the first sliding block 32, and the second sliding groove 34 limits the second sliding block 35, so that the first extrusion plate 33, the second extrusion plate 36, the vertical fixed plate 2 and one of the horizontal fixed plates 1 are squeezed against the template. When squeezing and clamping, the extrusion shell 41 will first contact the template. Therefore, the movement of the two extrusion plates will cause the template to generate a reaction force on the extrusion shell 41, thereby causing the extrusion plates to move inward, and then extruding the connecting rod 46, causing the connecting rod 46 to push the resistance plate 45, and then causing the push rod 49 to squeeze the argon gas in the fixed sleeve 410, thereby squeezing the moving block 44 through the resistance plate 45, and then driving the conductive sheet 47 to slide on the resistance plate 48. When the current passing through the sliding rheostat changes, the current change is detected by the current detection template in the PLC controller. When the current change is detected, the template is clamped and the corresponding motor is controlled to stop running through the PLC controller; Then the argon gas is continuously introduced between the fixed sleeve 410 and the push rod 49 by the PLC controller controlling the air extraction pump 412, and the amount of argon gas introduced is one fourth of the amount of argon gas between the fixed sleeve 410 and the push rod 49 in the initial state, which is to adjust the elasticity and rigidity, enhance the stable support of the clamping state of the template, prevent displacement deformation; optimize the buffer performance, absorb vibration impact energy; and can be fine-tuned according to the actual situation of the template to adapt to different working conditions, ensure construction quality and safety (the more argon gas introduced, the greater the elasticity, because argon gas as a gas has compressibility, when the amount of argon gas increases, the air cushion layer formed by the gas between the fixed sleeve 410 and the push rod 49 will be thicker, and the increase in the number of gas molecules makes the air cushion layer can withstand greater pressure and greater elastic deformation, thus showing greater elasticity, but it is also more difficult to be extruded) ; Since there are two clamps at the top and bottom of the outer wall of the column template, the infrared rays emitted by the uppermost infrared emitter 7 are received by the lower infrared receiver, and the distance between each clamp is calculated. Since there are clamps at the top and bottom, the distance between the top and bottom clamps can also be calculated.

[0031] In building construction, concrete has a certain gravity, and during the pouring process, as the height increases, the lower concrete gradually increases the gravity of the upper concrete, just like stacking objects, the bottom layer bears more weight, so the concrete pressure on the lower column template will be greater than the upper part.

[0032] Based on the fact that the pressure on the column template at different heights is different, in order to ensure that the template remains stable during the concrete pouring process and ensure the forming quality of the concrete member, it is necessary to further adjust the extrusion force of the clamp on the column template. After measuring the distance between the clamps by the infrared distance meter, these data will be transmitted to the PLC controller in real time. The PLC controller has a pre-set algorithm for pressure and distance inside, which is derived from a large amount of experimental data and engineering experience, for example, when the clamp spacing is small, it indicates that the column template at this position is under relatively large concrete pressure; when the clamp spacing is large, it indicates that the column template at this position is under relatively small pressure.

[0033] According to the calculation results of the algorithm, the PLC controller controls the vacuum pump 412 to continue to introduce argon gas between the fixed sleeve 410 and the push rod 49. Taking into account the characteristic that the concrete pressure on the column formwork gradually increases from top to bottom, in order to better adapt to this pressure change and maintain structural stability and reasonable force, the amount of argon gas introduced between the fixed sleeve 410 and the push rod 49 is less as it goes up. The specific amount is determined according to actual conditions. For example, in actual projects, through preliminary monitoring and data analysis of the pressure of column formworks at different heights, it is determined that for fixtures within 1 meter from the bottom of the column formwork, the final amount of argon gas introduced between the fixed sleeve 410 and the push rod 49 is 1.5 times the initial amount; for fixtures within 1-3 meters from the bottom, the final amount of argon gas introduced is 1.2 times the initial amount; for fixtures more than 3 meters from the bottom, the final amount of argon gas introduced is 1.1 times the initial amount. In this way, by precisely adjusting the amount of argon gas, the squeezing force of the fixture on the column formwork can be effectively adjusted to avoid displacement and deformation of the formwork due to uneven force, thereby ensuring construction quality and safety.

[0034] And when pouring concrete, when the template at a certain place pushes the extrusion shell 41 to move into the extrusion groove 42, the resistance plate 45 drives the moving block 44 to move synchronously, and then drives the conductive plate 47 to slide on the resistance plate 48, thereby adjusting the current passing through the sliding rheostat. When the current passing through the sliding rheostat increases, it means that the concrete extrusion template moves outward. Therefore, it is necessary to control the vacuum pump 412 through the PLC controller to re-introduce argon gas between the fixed sleeve 410 and the push rod 49, so that the current passing through the sliding rheostat returns to its previous size, so as to ensure that the template system can continue to adapt to the pressure changes during the concrete pouring process.
