Description

Technical Field

[0001] This invention relates to the field of template installation technology, and in particular to an auxiliary installation tool for prefabricated templates used in building construction. Background Technology

[0002] When installing the formwork, first tilt the formwork against the side of the wall's steel reinforcement frame. After all the formwork is placed, adjust it to a vertical position and assemble and fix it. Once the formwork is fixed, concrete can be poured.

[0003] When adjusting the template from an inclined state to a vertical state, a pry bar is needed to pry the bottom of the template. Since the template is made of wood, the prying process can easily damage the template, making it impossible for the bottom to fully adhere to the ground. If the damage is serious, the template needs to be replaced. There is a need for further optimization in reducing template damage. Therefore, this application provides an auxiliary installation tool for prefabricated templates in building construction to meet the needs. Summary of the Invention

[0004] This invention provides an auxiliary installation tool for prefabricated formwork in building construction to solve the problem that formwork is easily damaged when moved by crowbars.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A prefabricated formwork auxiliary installation tool for building construction includes a base plate, with two support blocks symmetrically fixed to the bottom of the base plate, and further includes: The snap-fit ​​mechanism includes a snap-fit ​​post rotatably connected to the top of the base plate. The snap-fit ​​post has a snap-fit ​​groove on its circumferential surface. A handle is installed at an angle on the side of the snap-fit ​​post away from the snap-fit ​​groove. The handle is used to rotate the snap-fit ​​post. When placing the template, it is located in the snap-fit ​​groove. When installing the template, rotate the snap-fit ​​post, and the template will disengage from the snap-fit ​​groove, with the circumferential surface of the snap-fit ​​post fitting against the side of the template.

[0006] Preferably, an arc-shaped surface is provided at the corner of the vertical surface of the snap-fit ​​groove.

[0007] Preferably, the bottom of the snap-fit ​​groove has an inclined surface, with the side of the inclined surface closer to the snap-fit ​​post being lower and the side of the inclined surface farther from the snap-fit ​​post being higher.

[0008] Preferably, a movable block is provided on the top of the base plate, and a cavity is opened inside the movable block. A rotating shaft is movably passed through the top of the movable block. The top of the rotating shaft is fixed to the bottom of the snap-fit ​​post. The bottom of the snap-fit ​​post is in contact with the top of the movable block. A limit block is fixed to the bottom of the rotating shaft, and the top of the limit block is in contact with the top of the inner wall of the cavity.

[0009] Preferably, the top of the base plate has a through hole, the outer wall of the movable block is slidably connected to the inner wall of the through hole, and the bottom of the snap-fit ​​post is fixed with a supporting spring, the bottom of the spring being fixed to the top of the base plate.

[0010] Preferably, a pad is fixed at the bottom of the movable block. The pad is a rubber block. After the template is placed in the snap-fit ​​groove, the snap-fit ​​column drives the pad to adhere to the ground through the movable block. The cross-sectional shape of the movable block is polygonal.

[0011] Preferably, the top of the snap-fit ​​post has a T-shaped groove, the side of the T-shaped groove has a clearance groove, a T-shaped block is snapped into the T-shaped groove, the handle is fixed to the side of the T-shaped block, the surface of the handle is slidably connected to the inner wall of the clearance groove, the side of the T-shaped block has a pressing surface, the bottom of the pressing surface is inclined towards the middle of the snap-fit ​​post, the top of the snap-fit ​​post is threaded with a bolt, the surface of the bolt is movably fitted with a limit plate, after the T-shaped block is snapped into the T-shaped groove, the limit plate is located at the top of the T-shaped block.

[0012] Preferably, a magnetic block is embedded in the bottom of the limiting plate, and the magnetic block is magnetically attracted to the top of the T-shaped block.

[0013] Preferably, the bottom of the handle is integrally formed with a horizontal part, and anti-slip stripes are formed on the circumferential surface of the horizontal part.

[0014] Preferably, the end of the horizontal portion is integrally formed with a bent portion, which bends upward.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above solution, by setting up a snap-fit ​​mechanism, when the template is placed at an angle, the bottom of the template is placed in the snap-fit ​​groove. The snap-fit ​​groove on the snap-fit ​​post limits the template and prevents the bottom of the template from sliding. When installing the template, turn both handles at the same time and turn the snap-fit ​​post. The corner of the snap-fit ​​groove will squeeze the template, causing the bottom of the template to move away from the snap-fit ​​groove. After the bottom of the template is removed from the snap-fit ​​groove, it will fall to the ground. The above method not only makes the template remove from the snap-fit ​​groove, but also moves the template to a vertical position. There is no need to move the template with a pry bar, reducing the possibility of template damage and protecting the template. Secondly, after the template is removed from the snap-fit ​​groove, the circumferential surface of the snap-fit ​​post will fit against the side of the template. At this time, the snap-fit ​​post can limit the template and make the template tend to be vertical, which facilitates the fixing between templates. After the template is fixed, the whole thing can be pulled away from the template, making the operation convenient.

[0016] By setting an arc-shaped surface, when the template is squeezed at the corner of the snap-fit ​​groove, the arc-shaped surface can further reduce the damage to the template, thereby protecting the template and increasing its durability.

[0017] By setting a slope, the template can reduce the possibility of it coming off the locking groove after being placed inside the slope, thereby further increasing the stability of the template during placement and preventing the template from tilting and falling.

[0018] By setting through holes, which provide channels for the vertical movement of the moving block, and because the moving block is polygonal, the locking post cannot easily drive the moving block to rotate horizontally during rotation, allowing the moving block to move only vertically. The polygonal design eliminates the need for guide posts and other structures, resulting in a simpler structure. Simultaneously, after the template is placed in the locking groove, the template will drive the locking post downwards, which in turn will drive the moving block downwards. The moving block will then cause the pad to adhere to the ground. This increases the contact area with the ground, thereby increasing friction and reducing the possibility of the tilted template causing the entire base plate to move, further increasing the stability of the template during placement.

[0019] By setting a T-slot, after the template is placed in the snap-fit ​​slot and the bottom of the moving block is attached to the ground, the T-shaped block at the end of the handle is inserted into the T-slot. Then, the limiting plate is rotated to the top of the T-shaped block to limit the T-shaped block. At this time, the T-shaped block serves as the handle. After the handle is installed, the bottom of the handle will be attached to the ground. If the template is blown by the wind, the handle will act as a tilt support, reducing the possibility of the base plate being tilted by the template, and further improving the stability of the template after placement. At the same time, after the bottom of the handle touches the ground, it can further increase the friction between the handle and the ground, reducing the possibility of the whole thing sliding on the ground.

[0020] The T-block is not only used to install the handle, but its side surface can also fit against the side of the template to limit its movement, thereby further reducing the possibility of the template tilting and falling over. When it is necessary to rotate the locking post, the T-block is removed and inserted into the T-slot in reverse. At this time, the handle is tilted upward, and then the locking post is rotated by the handle to avoid jamming between the handle and the base plate, thus improving the smoothness of operation.

[0021] By setting up a magnetic block, when the limiting plate is attached to the top of the T-block, the magnetic block is magnetically attracted to the top of the T-block. In this way, the limiting plate and the T-block can be prevented from separating, thus improving stability.

[0022] By setting a horizontal section, the contact area between the handle and the ground can be further increased, preventing the bottom of the handle from inserting into the ground due to force when the handle is tilted to support the template. This not only improves the support capacity but also reduces damage to the ground.

[0023] By incorporating a bend, the handle is designed to provide a gripping space for the hand, making it easier to pull the handle upwards. Attached Figure Description

[0026] As shown in the figure, specific structures and devices are labeled in the figure to clearly illustrate the structure of the embodiments of the present invention. However, this is only for illustrative purposes and is not intended to limit the present invention to the specific structure, device and environment. Those skilled in the art can adjust or modify these devices and environments according to specific needs, and such adjustments or modifications are still included in the scope of the appended claims. Detailed Implementation

[0027] The following is a detailed description of an auxiliary installation tool for prefabricated formwork in building construction provided by the present invention, with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0028] like Figures 1-8 As shown, an embodiment of the present invention provides an auxiliary installation tool for prefabricated formwork in building construction, including a base plate 1, with two support blocks 2 symmetrically fixed to the bottom of the base plate 1, and further including: The snap-fit ​​mechanism 3 includes a snap-fit ​​post 4 rotatably connected to the top of the base plate 1. The circumferential surface of the snap-fit ​​post 4 is provided with a snap-fit ​​groove 5. A handle 17 is installed at an angle on the side of the snap-fit ​​post 4 away from the snap-fit ​​groove 5. The handle 17 is used to rotate the snap-fit ​​post 4. When the template is placed, it is located in the snap-fit ​​groove 5. When installing the template, the snap-fit ​​column 4 is rotated, and the template is disengaged from the snap-fit ​​groove 5. The circumferential surface of the snap-fit ​​column 4 is attached to the side of the template. The base plate 1 is the overall load-bearing base of the equipment, used to support the snap-fit ​​mechanism 3 and various supporting structures, and to bear the load generated by the placement of the template. Two support blocks 2 are symmetrically fixed at the bottom of the base plate 1 to provide horizontal support for the base plate 1, ensuring the stability of the foundation when the equipment is placed on the construction ground and preventing the equipment from tilting and shaking. The snap-fit ​​mechanism 3 is the core working structure of the equipment, used to realize the temporary limiting, posture adjustment and auxiliary installation of the template. The snap-fit ​​column 4 is rotatably installed on the top of the base plate 1, serving as the core carrier for snap-fit ​​limiting and rotation adjustment, and can be freely rotated to switch working states. The snap-fit ​​groove 5 is opened on the circumferential surface of the snap-fit ​​column 4 to snap into the bottom of the template, providing fixed-point limiting for the tilted template, restricting the bottom slippage of the template, and maintaining the tilted posture of the template during temporary placement. The handle 17 is tilted and installed on the outside of the snap-fit ​​column 4 as a manual force application component, providing a force application point for the rotation adjustment of the snap-fit ​​column 4 and reducing the rotation operation force.

[0029] like Figure 2 As shown in this embodiment, an arc-shaped surface 7 is provided at the corner of the vertical surface of the snap-fit ​​groove 5. During use, as the snap-fit ​​column 4 rotates and the snap-fit ​​groove 5 disengages from the template, the arc-shaped surface 7 flexibly contacts the bottom corner of the template. Compared with a right-angle structure, this eliminates the problem of squeezing, scratching, and damage to the template caused by sharp corners, and significantly reduces wear and tear during template assembly and disassembly. At the same time, the arc-shaped surface 7 has a guiding transition function, which makes the process of the bottom of the template disengaging from the snap-fit ​​groove 5 smoother and without any jamming or sticking. This not only protects the structural integrity of the prefabricated template, but also improves the smoothness of template posture adjustment and extends the repeated service life of the template.

[0030] like Figure 6 As shown in this embodiment, the bottom of the snap-fit ​​groove 5 is provided with an inclined surface 6. The side of the inclined surface 6 closer to the snap-fit ​​post 4 is lower, and the side of the inclined surface 6 away from the snap-fit ​​post 4 is higher. When the template is placed at an angle for pre-fixing, the bottom of the template is attached to the surface of the inclined surface 6. The height difference of the inclined surface 6 can form a snap-fit ​​constraint on the bottom of the template, restricting the template from sliding outward and detaching from the snap-fit ​​groove 5, and offsetting the outward sliding torque generated by the template's own inclination. At the same time, the inclined surface can fit the inclination angle of the bottom of the template, increase the contact support area, avoid the template bottom from tilting up due to single point of force, effectively improve the stability of the temporary placement of the template, reduce the safety hazards of accidental tilting and falling of the template, and adapt to complex working conditions such as wind and slight vibration at the construction site.

[0031] like Figure 4As shown, in this embodiment, a movable block 9 is provided on the top of the base plate 1. A cavity is opened inside the movable block 9. A rotating shaft 12 is movably passed through the top of the movable block 9. The top of the rotating shaft 12 is fixed to the bottom of the locking post 4. The bottom of the locking post 4 is in contact with the top of the movable block 9. A limiting block 13 is fixed to the bottom of the rotating shaft 12. The top of the limiting block 13 is in contact with the top of the inner wall of the cavity. A through hole 8 is opened on the top of the base plate 1. The outer wall of the movable block 9 is slidably connected to the inner wall of the through hole 8. A supporting spring 10 is fixed to the bottom of the locking post 4. The template is fixed to the top of the base plate 1. When in use, the template is placed in the snap-fit ​​groove 5, which generates downward pressure, squeezing the snap-fit ​​post 4 and compressing the spring 10. This causes the moving block 9 to slide downward along the through hole 8, achieving adaptive settlement and conforming to the ground to complete anti-slip fixation. When the template is disassembled and the pressure is removed, the spring 10 rebounds by its own elasticity, pushing the snap-fit ​​post 4 and the moving block 9 to automatically reset and return to the initial working state. There is no need for manual adjustment and reset, which simplifies the operation process. At the same time, the spring 10 can buffer the impact load when the template is placed, reducing the wear and tear on the equipment structure.

[0032] like Figure 4 As shown in this embodiment, a pad 11 is fixed to the bottom of the movable block 9. The pad 11 is a rubber block. After the template is placed in the snap-fit ​​groove 5, the snap-fit ​​column 4 drives the pad 11 to adhere to the ground through the movable block 9. The movable block 9 has a polygonal cross-sectional shape. The polygonal structure of the movable block 9 cooperates with the inner wall of the through hole 8, which can completely restrict the circumferential rotation of the movable block 9 and prevent the snap-fit ​​column 4 from rotating synchronously with the movable block 9. There is no need to add an additional guide limit structure, which simplifies the overall structure of the equipment. When in use, after the template is placed and pressure is applied, the movable block 9 moves down and drives the rubber pad 11 to adhere tightly to the construction ground. Compared with the rigid structure, the rubber pad 11 can increase the friction coefficient between the equipment and the ground, greatly improve the overall anti-slip ability of the equipment, effectively resist the lateral thrust generated by the template tilt, and prevent the overall slippage of the equipment. At the same time, the rubber material can adapt to the uneven working conditions of the ground, with stronger adhesion, and can also buffer the vibration of the equipment, reduce structural noise and wear, and protect the construction ground from being damaged by the rigid structure.

[0033] like Figure 4 , Figure 5 and Figure 8As shown, in this embodiment, a T-shaped groove 14 is provided on the top of the snap-fit ​​post 4, and an avoidance groove 16 is provided on the side of the T-shaped groove 14. A T-shaped block 15 is snapped into the T-shaped groove 14. A handle 17 is fixed to the side of the T-shaped block 15, and the surface of the handle 17 is slidably connected to the inner wall of the avoidance groove 16. A pressing surface 18 is provided on the side of the T-shaped block 15, and the bottom of the pressing surface 18 is inclined towards the middle of the snap-fit ​​post 4. A bolt 22 is threadedly connected to the top of the snap-fit ​​post 4, and a limiting plate 21 is movably sleeved on the surface of the bolt 22. After the T-shaped block 15 is snapped into the T-shaped groove 14, the limiting plate 21 is located on the top of the T-shaped block 15. During use, during the temporary placement stage of the template, the T-shaped block 15 is inserted into the T-shaped groove 14 in the forward direction. The handle 17 is assembled with the clearance groove 16. The bolt 22 is rotated to drive the limiting plate 21 to press against the top of the T-block 15, thus fixing the handle 17. At this time, the inclined extrusion surface 18 is in contact with the side wall of the template, limiting the template a second time and preventing the template from tipping over. During the template rotation adjustment stage, the T-block 15 can be removed and inserted in the opposite direction to tilt the handle 17 upward, avoiding interference with the base plate 1 and ensuring smooth rotation operation. The detachable structure allows for flexible switching of the working posture of the handle 17, adapting to both support and operation conditions, improving the adaptability and practicality of the equipment. The bottom of the limiting plate 21 is embedded with a magnetic block 23, which is magnetically attracted to the top of the T-block 15 to prevent the limiting plate 21 from detaching from the T-block 15 and improve stability.

[0034] like Figure 8 As shown in this embodiment, the bottom of the handle 17 is integrally formed with a horizontal part 19. Anti-slip stripes 24 are formed on the circumferential surface of the horizontal part 19. During use, when the handle 17 is assembled in the forward direction as an oblique support structure, the horizontal part 19 is horizontally in contact with the ground. Compared to point or line contact, this can evenly distribute the support pressure, preventing the bottom of the handle 17 from being forced into the soft construction ground. This protects the ground structure and improves support stability. The anti-slip stripes 24 on the surface increase the frictional resistance between the horizontal part 19 and the ground, preventing slippage and displacement during support, and effectively resisting the side slippage of the template. To ensure the safety of temporary placement of the template against pressure and wind, the end of the horizontal section 19 is integrally formed with a bent section 20. The bent section 20 bends upward. When it is necessary to disassemble or adjust the position of the handle 17 or store the equipment, the bent section 20 can serve as a hand gripping force point, providing operators with a convenient gripping and lifting position without having to pry the handle 17, greatly reducing the difficulty of disassembling, assembling, and reversing the handle 17. At the same time, the bending structure of the bent section 20 can prevent the sharp end from hitting the operator, improving the safety of construction operations and optimizing the overall operating experience of the equipment.

[0035] Working principle: The whole unit is moved to the side of the wall steel reinforcement frame, so that the bottom plate 1 is stably supported on the ground by the two bottom support blocks 2. The template is placed at an angle so that the bottom of the template is inserted into the snap-fit ​​groove 5 of the snap-fit ​​column 4. The slope 6 at the bottom of the snap-fit ​​groove 5 uses the height difference to hold the bottom of the template, restricting the template from sliding, improving the placement stability and preventing the template from tipping over. After the template is placed, its own weight causes the locking column 4 to move downwards, compressing the bottom spring 10, which in turn causes the rotating shaft 12 and the polygonal moving block 9 to slide vertically down along the through hole 8 of the base plate 1. This results in the rubber pad 11 at the bottom of the moving block 9 being tightly attached to the ground, increasing the contact area and friction between the equipment and the ground, and effectively preventing the template from tilting and causing the entire equipment to slide. Align the T-shaped block 15 at the end of the handle 17 with the T-shaped groove 14 at the top of the locking post 4 and insert it so that the handle 17 fits against the inner wall of the clearance groove 16 to complete the initial positioning. Rotate the limiting plate 21 and press the limiting plate 21 against the top of the T-shaped block 15. At the same time, the magnetic block 23 at the bottom of the locking post 4 magnetically fixes the T-shaped block 15. At this time, the handle 17 is tilted downward and the bottom horizontal part 19 is in contact with the ground. The handle 17 forms an oblique support structure to resist the wind force and the pressure of the template tilting, and to prevent the bottom plate 1 from tilting and becoming unstable. At the same time, the pressing surface 18 on the side of the T-shaped block 15 fits against the side of the template, limiting the template a second time and preventing the template from tilting and slipping. When the template is ready for formal installation, rotate the limiting plate 21 to disengage it from the top of the T-block 15, remove the T-block 15 and handle 17, insert the T-block 15 into the T-groove 14 in the opposite direction, and tilt the handle 17 upward to avoid structural interference with the base plate 1 and ensure smooth operation. Hold the handle 17 and rotate the locking post 4. The arc surface 7 of the corner of the locking groove 5 gradually squeezes the bottom of the template, pushing the bottom of the template to slide away from the locking groove 5, so that the template can be smoothly separated from the locking groove 5. After the template is separated, it stands upright naturally. At the same time, the outer circumference of the locking post 4 is tightly attached to the side of the template to laterally limit the upright template and keep the template in a vertical position. There is no need to pry the template with a crowbar, avoiding damage to the template and making it convenient for construction personnel to carry out template splicing and fixing operations. After the template is firmly spliced ​​and installed, drag the base plate 1 as a whole to separate the snap-fit ​​column 4 from the side of the template, thus completing the template auxiliary installation work.

[0036] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
