Description

Technical Field

[0001] This utility model relates to the field of precast beam formwork technology, and more specifically, to a limiting adjustment mechanism for precast beam formwork. Background Technology

[0002] Precast beams are mainly produced in factories and then transported to the site for installation. During the precast beam manufacturing process, corresponding templates are used to assist in production. Precast beam templates are molds used to produce precast beams, ensuring that the required shape, size, and surface quality are maintained during concrete pouring and hardening.

[0003] Existing patent CN218227176U provides a precast beam formwork, including a bottom mold, two side molds, two end molds, and several secondary beam slot molds. The two side molds are respectively located on the front and rear sides of the bottom mold, and the two end molds are respectively located at the left and right ends of the bottom mold. The secondary beam slot molds are fixed to the side molds. Each side mold includes a side mold panel and fixed back ribs fixed to the side mold panel. Wedge-shaped fastening boxes are provided on both the front and rear sides of the bottom mold, with an inclined surface at the top. The upper ends of the fixed back ribs of the two side molds are connected by fastening bolts. Using this precast beam formwork, the side molds do not need to be removed during the entire process of inserting the reinforcing cage and demolding the precast beam. The end molds and secondary beam slot molds can be infinitely adjusted, simplifying the construction process, reducing labor intensity, and improving work efficiency.

[0004] However, the existing device still has shortcomings: the installation position of the fastening screw is fixed, but the template base will gradually wear out after long-term use, which will cause the installation position of the fastening screw to deviate. This will make it impossible to complete the installation and fixing of the fastening screw, and it will be necessary to repair or replace it, which will cause trouble for the installation work of the staff and waste a lot of time and energy.

[0005] Therefore, it is necessary to provide a limit adjustment mechanism for precast beam formwork to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this utility model is to provide a limiting adjustment mechanism for precast beam formwork to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A limiting and adjusting mechanism for precast beam formwork is installed on the formwork, which includes a bottom formwork and side formwork, comprising: Multiple bases are provided at the lower end of the bottom mold, and each base is provided with two connecting sleeves, each connecting sleeve having an internal groove. The lower end of the limiting post is slidably connected to the built-in groove, and the upper end of the limiting post moves through the upper wall of the connecting sleeve. A fastening screw is installed between the two limiting posts of each base. An adjustment component, located on the connecting sleeve, is used to adjust the height of the limiting post.

[0008] Furthermore, the outer wall of the limiting post is provided with multiple adjustment holes, and the adjustment component includes: A transmission seat is disposed on the outer wall of the connecting sleeve, and a limiting rod adapted to the adjusting hole is provided inside the transmission seat, one end of the limiting rod extending movably into the built-in groove; A transmission assembly, mounted on the transmission base, is used to drive the limiting rod to move.

[0009] Furthermore, a transmission cavity is formed within the transmission seat, and the transmission assembly includes: The adapter slide is slidably connected to the inner wall of the transmission cavity. One end of the adapter slide is provided with a bearing, and the other end is connected to the limiting rod. A screw is threaded to the side wall of the transmission seat, and one end of the screw extends into the transmission cavity and is connected to the adapter slide plate.

[0010] Furthermore, the end of the transfer slide away from the bearing is provided with a plurality of first elastic elements, and the other end of the first elastic elements is connected to the inner wall of the transmission cavity.

[0011] Furthermore, the inner wall of the transmission cavity is provided with a sliding groove, and a slider connected to the transition slide plate is slidably connected in the sliding groove.

[0012] Furthermore, the bottom of the limiting post is provided with a bottom support plate that is slidably connected to the built-in groove, and a second elastic element is provided between the bottom support plate and the bottom wall of the built-in groove.

[0013] Furthermore, the limiting post has an inner cavity, and an installation block that is threadedly connected to the fastening screw is slidably connected inside the inner cavity. A third elastic element is provided between the installation block and the bottom wall of the inner cavity.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: When the base is worn or the foundation is not level, the height of the limiting posts on both sides of each base is not equal. The height of the limiting posts can be adjusted by operating the adjustment component so that the two limiting posts on each base are at the same corresponding height. Then, the two limiting posts can be connected by fastening screws, which greatly facilitates the installation of fastening screws on the limiting posts. It is highly flexible, saves time, improves installation efficiency, and eliminates the need for maintenance and replacement, saving costs. At the same time, it reduces cumbersome steps, reduces the trouble and labor intensity of workers, and has high practicality. After adjusting the height of the limit post, the position of the limit post is then locked by adjusting the component. This prevents the limit post from shaking during use, greatly improving the stability of the limit post and the fastening screw, and enhancing the performance. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-7 A limiting adjustment mechanism for precast beam formwork is installed on the formwork, which includes a bottom formwork 1 and side formwork 2, comprising: Multiple bases 3 are located at the lower end of the bottom mold 1. Each base 3 is provided with two connecting sleeves 4, and the connecting sleeves 4 have built-in grooves 5. The lower end of the limiting post 6 is slidably connected to the built-in groove 5, and the upper end of the limiting post 6 is movably connected through the upper wall of the connecting sleeve 4. A fastening screw 7 is installed between the two limiting posts 6 of each base 3. Adjustment component 8, located on connecting sleeve 4, is used to adjust the height of limit post 6.

[0019] In use, the two limiting posts 6 on each base 3 are connected by the fastening screws 7, and the two limiting posts 6 on the base 3 play a limiting and supporting role for the side molds 2 on both sides.

[0020] After a period of use, if the base 3 becomes worn or the foundation is not level, the heights of the limiting posts 6 on both sides of each base 3 will not be equal. The height of the limiting posts 6 can be adjusted by operating the adjusting parts 8 on each connecting sleeve 4, so that the two limiting posts 6 on each base 3 are at the same corresponding height. Then, the two limiting posts 6 on both sides can be connected by the fastening screws 7, which greatly facilitates the installation of the fastening screws 7 on the limiting posts 6. It is highly flexible, saves time, improves installation efficiency, eliminates the need for maintenance and replacement, saves costs, reduces tedious work steps, reduces the trouble and labor intensity of workers, and has high practicality.

[0021] After adjusting the height of the limiting post 6, the position of the limiting post 6 is then locked by the adjusting component 8. This prevents the limiting post 6 from shaking during use, greatly improving the stability of the limiting post 6 and the fastening screw 7, and enhancing the performance.

[0022] For preferred options, please refer to [link / reference]. Figure 1-2 and Figure 4-6 The outer wall of the limiting post 6 is provided with multiple adjustment holes 9, and the adjustment component 8 includes: The transmission seat 81 is located on the outer wall of the connecting sleeve 4. The transmission seat 81 is provided with a limiting rod 82 that is adapted to the adjusting hole 9. One end of the limiting rod 82 extends movably into the built-in groove 5. The transmission assembly 83 is mounted on the transmission base 81 and is used to drive the limiting rod 82 to move.

[0023] Specifically, when the height of the limiting post 6 needs to be adjusted, the transmission assembly 83 drives the limiting rod 82 to move. When the limiting rod 82 moves towards the transmission seat 81, it gradually disengages from the adjustment hole 9 of the limiting post 6. The limiting post 6 then loses its locking restraint, allowing it to move up and down to adjust its height. After the height of the limiting post 6 is adjusted, the transmission assembly 83 drives the limiting rod 82 again, causing it to move and insert into the adjustment hole 9 of the limiting post 6. This restricts the height position of the limiting rod 82, ensuring the stability of the limiting post 6 and thus improving the stability of both the limiting post 6 and the fastening screw 7. For preferred options, please refer to [link / reference]. Figure 5-6 The transmission seat 81 has a transmission cavity 10, and the transmission assembly 83 includes: The adapter slide plate 831 is slidably connected to the inner wall of the transmission cavity 10. One end of the adapter slide plate 831 is provided with a bearing 832, and the other end is connected to the limiting rod 82. The screw 833 is threaded to the side wall of the transmission seat 81, and one end of the screw 833 extends into the transmission cavity 10 and is connected to the adapter slide plate 831.

[0024] With this design, by rotating the screw 833, one end of the screw 833 will rotate through the bearing 832. Since the screw 833 is threadedly connected to the transmission seat 81, the screw 833 will move horizontally while rotating. The screw 833 will then drive the adapter slide 831 to move along the inner wall of the transmission cavity 10. The adapter slide 831 will then drive the limiting rod 82 to move. Thus, the forward and reverse rotation of the screw 833 can drive the limiting rod 82 to move back and forth. The adapter slide 831 can improve the stability of the movement of the limiting rod 82 and improve the limiting stability effect of the limiting rod 82 on the limiting post 6.

[0025] For preferred options, please refer to [link / reference]. Figure 6 The adapter slide 831 is provided with a plurality of first elastic elements 11 at one end away from the bearing 832. The other end of the first elastic element 11 is connected to the inner wall of the transmission cavity 10. The first elastic element 11 in this application can be a spring.

[0026] This design allows the first elastic element 11 to provide uniform support for the sliding plate 14, ensuring its smooth sliding within the limiting groove. Simultaneously, when the screw 833 is rotated, causing the limiting rod 82 to disengage from the adjusting hole 9, the adapter slide 831 needs to move the limiting rod 82 back to its original position. However, if only the screw 833 is reversed during the return stroke, thread clearance, frictional resistance, or component tolerances may cause the adapter slide 831 to return unevenly. Therefore, the reset elasticity of the first elastic element 11 assists in the rapid return of the adapter slide 831, reducing resistance or jamming caused by mechanical friction.

[0027] For preferred options, please refer to [link / reference]. Figure 6 The inner wall of the transmission cavity 10 is provided with a groove 12, and a slider 13 connected to the adapter slide plate 831 is slidably connected in the groove 12.

[0028] This design allows the slider 13 to move along the slide groove 12 when the adapter slide plate 831 moves, thereby improving the stability and smoothness of the movement of the adapter slide plate 831 and the limiting rod 82.

[0029] For preferred options, please refer to [link / reference]. Figure 1-4 and Figure 6 The bottom of the limiting post 6 is provided with a bottom support plate 14 that is slidably connected to the built-in groove 5. A second elastic element 15 is provided between the bottom support plate 14 and the bottom wall of the built-in groove 5. The second elastic element 15 in this application can be a spring.

[0030] With this design, when the height of the limiting post 6 needs to be adjusted, the limiting rod 82 is disengaged from the adjustment hole 9 of the limiting post 6 by rotating the screw 833. At this time, the second elastic element 15 can buffer the bottom support plate 14 and the limiting post 6 and move them upward. On the one hand, it can prevent the limiting post 6 from falling suddenly and quickly after the limiting rod 82 is removed, reducing the damage to the limiting post 6. On the other hand, the second elastic element 15 can make the limiting rod 82 return to its upward position, making it easier for the staff to move and adjust the limiting post 6, reducing the difficulty of manual operation.

[0031] For preferred options, please refer to [link / reference]. Figure 3 and Figure 5 The side wall of the built-in groove 5 is provided with a stabilizing groove 19, and the inner wall of the stabilizing groove 19 is slidably connected to a connecting block 20 connected to the bottom support plate 14. When the limiting post 6 moves up and down, it will drive the connecting block 20 to slide along the stabilizing groove 19 through the bottom support plate 14, which can improve the stability of the bottom support plate 14 and the limiting post 6 sliding in the built-in groove 5.

[0032] For preferred options, please refer to [link / reference]. Figure 1 , Figure 4 and Figure 7The limiting post 6 has an inner cavity 16 inside, and a mounting block 17 that is threadedly connected to the fastening screw 7 is slidably connected inside the inner cavity 16. A third elastic element 18 is provided between the mounting block 17 and the bottom wall of the inner cavity 16. The third elastic element 18 in this application can be a spring.

[0033] This design allows the mounting block 17 to move along the inner cavity 16 after the approximate position of the limiting post 6 is adjusted by adjusting component 8. This, in turn, allows for further adjustment of the height of the mounting block 17, enabling the fastening screw 7 to be installed at a more precise height and improving its installation effect. When the mounting block 17 is moved into the inner cavity 16, it compresses the third elastic element 18, which enhances the stability of the mounting block 17 during installation.
