Description

Technical Field

[0001] This utility model relates to the technical field of formwork support equipment, and more specifically, to a cast-in-place beam formwork disassembly and assembly support adjustment device. Background Technology

[0002] In building construction, the construction quality and efficiency of cast-in-place beams are of paramount importance. As a key piece of equipment in cast-in-place beam construction, the performance of the formwork dismantling and support adjustment device directly affects the construction progress, cost, and the forming quality of the beam. Existing technical solutions for reinforcing beam side formwork are cumbersome and involve a large amount of installation and dismantling work. In addition, when using tie rods for reinforcement, the tie rod sleeves are prone to breakage, making it impossible to remove the tie rods, which increases the cost of the construction project.

[0003] A search revealed that Chinese Patent CN214169914U discloses an adjustable cast-in-place structural beam formwork support device. In this structure, both sets of support components can slide on the horizontal bar, increasing the flexibility of the invention and facilitating the adjustment of the distance between the two vertical plates of the support components. Furthermore, the locking component can fix the position of the support components on the horizontal bar. A stopper designed at the bottom of the horizontal bar can limit the fixing component between adjacent stoppers, so that after the structural beam formwork is poured, the fixing component is blocked by the stopper, thus fixing the position of the support component on the horizontal bar. The design of the limiting component locks the position of the support component on the horizontal bar. Secondly, the height of the vertical plates matches the height of the structural beam, enabling support for structural beam formwork of different heights while avoiding the increased cost of excessive use of tie rods.

[0004] However, in actual use, from the perspective of the locking structure, the blocking element can only limit the fixing element between adjacent blocking elements, which is a passive limiting and cannot form an active locking force. In addition, the contact area with the supporting component is small. Under the action of construction vibration, it is easy to loosen due to excessive local stress, which in turn causes the supporting component to slide slightly on the crossbar. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a cast-in-place beam formwork disassembly and assembly support adjustment device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A cast-in-place beam formwork disassembly and assembly support adjustment device includes a horizontal bar, a plurality of stabilizing frames are fixedly installed on the top of the horizontal bar, a stabilizing plate is slidably installed inside the stabilizing frame, and a fixing mechanism is installed on the top of the stabilizing plate; The fixing mechanism includes a fixing frame fixedly mounted on the top of the stabilizing plate. Multiple U-shaped sliders are slidably arranged inside the fixing frame. A fixing plate is fixedly mounted on the top of the U-shaped sliders. Multiple rollers are rotatably arranged on the inner wall of the U-shaped sliders. A connecting groove is opened on the surface of the fixing plate. Multiple fixing grooves are opened on the surface of the fixing frame. U-shaped fixing frames are inserted into the fixing grooves and connecting grooves. The U-shaped fixing frames and the fixing plate are locked together by bolts.

[0007] By adopting the above technical solution, the support height can be flexibly adjusted to adapt to different beam pouring requirements, and the fixed plate can be quickly positioned laterally, adapting to various widths of templates, and forming a stable connection to prevent displacement during template construction.

[0008] As a further description of the above technical solution: an angle adjustment mechanism is provided on one side of the fixed plate. The angle adjustment structure includes a connecting frame fixedly disposed on one side of the fixed plate, a connecting plate rotatably disposed inside the connecting frame, a rubber layer fixedly disposed on one side of the connecting plate, a connecting rod fixedly disposed inside the connecting plate, one end of the connecting rod rotatably connected to the inner wall of the connecting frame, and the other end of the connecting rod penetrating the connecting frame and extending outward from the connecting frame. A handle is fixedly provided at one end of the connecting rod, a positioning block is fixedly provided on the surface of the connecting rod, a stabilizing block is fixedly provided on one side of the fixing plate, a positioning ring is fixedly provided on one side of the stabilizing block, and multiple threaded holes are opened on the surface of the positioning ring. The positioning block and the threaded holes are locked together by bolts.

[0009] By adopting the above technical solution: by turning the connecting rod with the handle, the connecting plate can be rotated flexibly within the connecting frame, quickly adjusting the tilt angle of the template to adapt to different beam slope requirements. Moreover, the threaded holes of the positioning block and the positioning ring are locked with bolts, which can accurately lock the adjustment angle and prevent angle deviation during construction.

[0010] As a further description of the above technical solution: the surface of the fixing plate is provided with a sliding groove, a slider is slidably arranged inside the sliding groove, an auxiliary rod is hinged to one side of the slider, and one end of the auxiliary rod is hinged to the surface of the connecting plate; The surface of the fixing plate is provided with multiple slots, and a baffle is inserted into the inside of each slot. The surface of the stabilizing plate is provided with scale lines, and the surface of the stabilizing plate is provided with multiple limiting grooves. The surface of the stabilizing frame is provided with through grooves. L-shaped plates are inserted into the limiting grooves and through grooves. The L-shaped plates are locked to the stabilizing frame by bolts.

[0011] By adopting the above technical solution, stable support is provided for angle adjustment, avoiding deformation under stress and enhancing the load-bearing capacity of the angle adjustment mechanism. Moreover, the baffle can be quickly installed through the slot, which can limit the side of the template and prevent lateral slippage, further improving the adjustment accuracy, support stability and operation convenience of the device, and adapting to more construction scenarios.

[0012] The technical effects and advantages of this utility model are as follows: By setting up a fixing mechanism, compared with the existing technology, the U-shaped slider and the fixing frame work together to achieve flexible lateral movement of the fixing plate with the help of rollers. This can quickly adapt to templates of different widths, greatly reducing positioning time. Moreover, after the U-shaped fixing frame is inserted into the fixing groove and the connecting groove, it can be locked with bolts to form a rigid fixation, preventing lateral displacement of the fixing plate during construction and ensuring the positioning accuracy of the template. In addition, the sliding structure of the stabilizing plate and the stabilizing frame, combined with the locking of the L-shaped plate and the limiting groove, can accurately adjust the height and fix it firmly to meet the construction needs of different beam heights. It also has a strong load-bearing capacity, ensuring the forming quality of the cast-in-place beam and enhancing construction safety. By incorporating an angle adjustment mechanism, compared to existing technologies, the angle of the connecting plate can be easily adjusted by driving the connecting rod with a handle. Combined with the bolt locking of the positioning block and positioning ring, the preset angle can be precisely fixed to meet the tilting requirements of different beams. Furthermore, the elastic deformation of the rubber layer can compensate for template errors and enhance fit. Secondly, the cooperation between the auxiliary rod and the slider improves stability during adjustment. During demolding, the fixing can be quickly released by reversing the operation. The overall design makes angle adjustment convenient and efficient, ensuring construction accuracy while simplifying the operation process and improving construction efficiency and safety.

[0020] The embodiments disclosed in this application are as follows: Figure 1-5 The cast-in-place beam formwork disassembly and assembly support adjustment device shown includes a horizontal bar 1, a plurality of stabilizing frames 2 are fixedly installed on the top of the horizontal bar 1, a stabilizing plate 3 is slidably installed inside the stabilizing frame 2, and a fixing mechanism is installed on the top of the stabilizing plate 3. The fixing mechanism includes a fixing frame 4 fixedly installed on the top of the stabilizing plate 3. Multiple U-shaped sliders 5 are slidably installed inside the fixing frame 4. A fixing plate 6 is fixedly installed on the top of the U-shaped sliders 5. Multiple rollers 7 are rotatably installed on the inner wall of the U-shaped sliders 5. A connecting groove is opened on the surface of the fixing plate 6. Multiple fixing grooves 8 are opened on the surface of the fixing frame 4. U-shaped fixing frames 9 are inserted into the fixing grooves 8 and the connecting grooves. The U-shaped fixing frames 9 and the fixing plate 6 are locked together by bolts. Align the stabilizing plate 3 with the inner groove of the stabilizing frame 2, slowly insert it and slide it upward. According to the design height of the template, determine the extension length through the scale lines on the surface of the stabilizing plate 3. Then, pass the L-shaped plate 24 through the through groove of the stabilizing frame 2 and insert it into the corresponding limiting groove 23 of the stabilizing plate 3. Use bolts to lock the L-shaped plate 24 to the stabilizing frame 2 to complete the height fixation. Furthermore, the U-shaped slider 5 is pushed within the fixed frame 4, and the friction is reduced by the roller 7 on the inner wall, which drives the fixed plate 6 to move along the length of the fixed frame 4. When the fixed plate 6 reaches the lateral positioning point of the template, the U-shaped fixed frame 9 is simultaneously inserted into the fixing groove 8 of the fixed frame 4 and the connecting groove of the fixed plate 6. The U-shaped fixed frame 9 and the fixed plate 6 are locked with bolts to achieve lateral position locking.

[0021] Reference Figure 2-3As shown, an angle adjustment mechanism is provided on one side of the fixed plate 6. The angle adjustment structure includes a connecting frame 10 fixedly disposed on one side of the fixed plate 6, a connecting plate 11 rotatably disposed inside the connecting frame 10, a rubber layer 12 fixedly disposed on one side of the connecting plate 11, a connecting rod 13 fixedly disposed inside the connecting plate 11, one end of the connecting rod 13 rotatably connected to the inner wall of the connecting frame 10, and the other end of the connecting rod 13 penetrating the connecting frame 10 and extending outward from the connecting frame 10. A handle 14 is fixedly provided at one end of the connecting rod 13, a positioning block 15 is fixedly provided on the surface of the connecting rod 13, a stabilizing block 16 is fixedly provided on one side of the fixing plate 6, a positioning ring 17 is fixedly provided on one side of the stabilizing block 16, and a plurality of threaded holes 18 are provided on the surface of the positioning ring 17. The positioning block 15 and the threaded holes 18 are locked together by bolts. Rotate handle 14 to drive connecting rod 13 to rotate, so that connecting plate 11 rotates within connecting frame 10. At the same time, observe the fit between rubber layer 12 and template at the preset angle. When the angle reaches the design value, align the corresponding threaded hole 18 of positioning ring 17 on positioning block 15 and stabilizing block 16, and tighten with bolts to complete angle fixing. During the process, the slider 20 slides along the groove 19, and the auxiliary rod 21 extends and retracts synchronously to provide support. After reaching the appropriate position, the baffle 22 is inserted into the slot on the surface of the appropriate fixing plate 6 to enhance stability.

[0022] Reference Figure 4-5 As shown, a groove 19 is provided on the surface of the fixing plate 6, and a slider 20 is slidably arranged inside the groove 19.

The surface of the fixing plate 6 has multiple slots, and a baffle 22 is inserted into the inside of the slots; The surface of the stabilizing plate 3 is provided with scale lines, and multiple limiting grooves 23 are provided on the surface of the stabilizing plate 3. The surface of the stabilizing frame 2 is provided with through grooves. L-shaped plates 24 are inserted into the limiting grooves 23 and through grooves. The L-shaped plates 24 are locked to the stabilizing frame 2 by bolts. The precast template is hoisted above the fixed plate 6 and slowly lowered so that the bottom surface of the template is in contact with the fixed plate 6, the side is in contact with the baffle 22, and the other side is in close contact with the rubber layer 12 of the connecting plate 11. The elastic deformation of the rubber layer 12 compensates for the surface error of the template. Furthermore, check the bolt torque of the U-shaped fixing frame 9, L-shaped plate 24, and positioning block 15, and tighten the bolts to the specified value with a torque wrench to ensure that the stabilizing plate 3 does not shake, the fixing plate 6 does not shift, and the connecting plate 11 is not loose. When the formwork needs to be removed, after the concrete strength reaches the demolding requirements, loosen the bolts of the positioning block 15 and the positioning ring 17, turn the handle 14 to rotate the connecting plate 11 outward to release the lateral pressure on the formwork, and use hoisting equipment to slowly lift the formwork away from the fixing plate 6. Then turn the handle 14 in the opposite direction to return the connecting plate 11 to the initial vertical position, slide the slider 20 to the end of the slide groove 19, and re-tighten the bolts of the positioning block 15 to prevent the connecting plate 11 from shaking during transportation.

[0023] Working principle of this utility model: This utility model is a support and adjustment device for disassembly and assembly of cast-in-place beam formwork. When using this device, the installation process is as follows: first, move the horizontal bar 1 to the construction area, align the bottom cone 25 with the ground, apply pressure to insert the cone 25 into the ground at least 30cm, and ensure that the abutment plate 26 is completely in contact with the ground. Through the anchoring effect of the cone 25 and the force distribution of the abutment plate 26, the initial fixation of the horizontal bar 1 is achieved. Then, align the stabilizing plate 3 with the inner groove of the stabilizing frame 2, slowly insert it and slide it upward. According to the design height of the template, determine the extension length through the scale lines on the surface of the stabilizing plate 3. Then, pass the L-shaped plate 24 through the through groove of the stabilizing frame 2 and insert it into the corresponding limiting groove 23 of the stabilizing plate 3. Use bolts to lock the L-shaped plate 24 to the stabilizing frame 2 to complete the height fixation. Furthermore, push the U-shaped slider 5 inside the fixed frame 4, reduce friction through the roller 7 on the inner wall, and drive the fixed plate 6 to move along the length direction of the fixed frame 4. When the fixed plate 6 reaches the horizontal positioning point of the template, insert the U-shaped fixed frame 9 into the fixing groove 8 of the fixed frame 4 and the connecting groove of the fixed plate 6 at the same time, and lock the U-shaped fixed frame 9 and the fixed plate 6 with bolts to achieve horizontal position locking. Next, turn the handle 14 to drive the connecting rod 13 to rotate, so that the connecting plate 11 rotates within the connecting frame 10. At the same time, observe the fit between the rubber layer 12 and the template at the preset angle. When the angle reaches the design value, align the positioning block 15 with the corresponding threaded hole 18 of the positioning ring 17 on the stabilizing block 16, and tighten it with bolts to complete the angle fixing. During the process, the slider 20 slides along the slide groove 19, and the auxiliary rod 21 extends and retracts synchronously to support it. After reaching the appropriate position, the baffle 22 is inserted into the slot on the surface of the appropriate fixing plate 6 to enhance stability. Then, the prefabricated template is hoisted above the fixed plate 6 and slowly lowered so that the bottom surface of the template is in contact with the fixed plate 6, the side is in contact with the baffle 22, and the other side is in close contact with the rubber layer 12 of the connecting plate 11. The elastic deformation of the rubber layer 12 compensates for the surface error of the template. Furthermore, check the bolt torque of the U-shaped fixing frame 9, L-shaped plate 24, and positioning block 15, and tighten the bolts to the specified value with a torque wrench to ensure that the stabilizing plate 3 does not shake, the fixing plate 6 does not shift, and the connecting plate 11 is not loose. When the formwork needs to be removed, after the concrete strength reaches the demolding requirements, loosen the bolts of the positioning block 15 and the positioning ring 17, turn the handle 14 to rotate the connecting plate 11 outward to release the lateral pressure on the formwork, and use hoisting equipment to slowly lift the formwork away from the fixing plate 6. Then turn the handle 14 in the opposite direction to return the connecting plate 11 to the initial vertical position, slide the slider 20 to the end of the slide groove 19, and re-tighten the bolts of the positioning block 15 to prevent the connecting plate 11 from shaking during transportation.
