Description

Technical Field

[0001] This application relates to the field of building construction technology, and in particular to a column formwork reinforcement system. Background Technology

[0002] In cast-in-place concrete structural engineering, square-section columns serve as the primary vertical load-bearing components, and their molding quality directly affects the safety and stability of the overall structure. The reliability of the formwork reinforcement system is crucial for ensuring the column's geometric dimensions, surface flatness, and concrete density.

[0003] Traditional formwork reinforcement systems mainly employ a construction process using steel pipe walers in conjunction with tie rods. This system requires drilling holes in the outer formwork before inserting the tie rods, a cumbersome and manual process with low efficiency. Furthermore, tie rods are disposable, resulting in a high wastage rate and making recycling impossible. Additionally, the lateral pressure from the large amount of concrete during steel pipe waler reinforcement causes stress concentration at the tightening points of the nuts. The plane of the column section containing the tie rods is only subjected to a unilateral tightening force along the length of the tie rods, all of which can lead to formwork deformation or bulging, resulting in grout leakage and quality problems on the column surface. Utility Model Content

[0004] In order to provide uniform fastening force to the cross-section column and improve construction efficiency, this application provides a column formwork reinforcement system.

[0005] This application provides a column formwork reinforcement system. The technical solution adopted is as follows: A column formwork reinforcement unit includes four reinforcing strips, each with a fixing member. The four reinforcing strips are connected end to end, and the fixing member is used to lock two adjacent reinforcing strips together, so that the four reinforcing strips are connected and tightened to surround the outside of the formwork.

[0006] By adopting the above technical solution, the reinforcing strips and fasteners are installed together around the outside of the formwork, eliminating the need for complex operations such as drilling and installation. Only four reinforcing strips are needed, secured to the outside of the formwork by the fasteners to complete the installation. This simple and convenient operation results in higher installation efficiency. After use, the fasteners and reinforcing strips can be directly removed, facilitating installation and removal and allowing for reuse. This avoids the problem of tie rods being fixed inside the cross-section column and unable to be removed, thus improving the utilization rate of the device. Simultaneously, the reinforcing strips are pulled close together on the outside of the formwork, preventing concentrated tightening force at the nut tightening points and avoiding single-point stress, thus preventing grout leakage in other parts of the cross-section column. The mutual tightening of the four reinforcing strips ensures balanced force on the cross-section column in the plane of the reinforcing strips, resulting in a strong and stable fastening effect. This prevents formwork bulging, deformation, and grout leakage, ensuring the quality of the formwork column.

[0007] Optionally, the fastener includes a bend, which is fixedly connected to one end of the reinforcing strip. The other end of the reinforcing strip has a fastening waist-shaped hole. The length direction of the fastening waist-shaped hole is consistent with the length direction of the reinforcing strip. The bend hook is fastened to the end of the adjacent reinforcing strip with the fastening waist-shaped hole. It also includes a fastening wedge, which is disposed through the fastening waist-shaped hole.

[0008] By adopting the above technical solution, the bent parts of the four reinforcing strips are hooked sequentially to the end of another reinforcing strip away from the bent part, forming a square ring that fits perfectly on the template. Then, the fastening wedge is inserted into the fastening waist-shaped hole, continuously pressing the reinforcing strip against the template. The structure of the fastening wedge further increases the pressure between the fastening wedge and the fastening waist-shaped hole when the concrete is poured and vibrates, strengthening the locking effect of the column template reinforcement unit and ensuring that a stable connection can be maintained under conditions such as vibration, thus avoiding structural failure.

[0009] Optionally, the bending and buckling directions of two adjacent reinforcing strips are set in opposite directions, while the bending and buckling directions of two opposite reinforcing strips are set in the same direction.

[0010] By adopting the above technical solution, with the two bends pointing upwards and the two bends pointing downwards, the four reinforcing strips are subjected to stable force, which ensures that the fastening force is always at the same level, resulting in a stable fastening effect and enhanced connection reliability.

[0011] Optionally, the length of the fastening waist-shaped hole is less than the widest width of the fastening wedge.

[0012] By adopting the above technical solution, the fastening wedge is inserted into the fastening waist-shaped hole to continuously press the four reinforcing strips against the template. The closer the fastening wedge is to the fastening waist-shaped hole, the tighter it is on the reinforcing strip. The width of the widest part of the fastening wedge is greater than the length of the fastening waist-shaped hole, ensuring that the fastening wedge is always located in the fastening waist-shaped hole and always plays the role of pressing the reinforcing strip, preventing the fastening wedge from falling directly out of the fastening waist-shaped hole and preventing the device from failing.

[0013] Optionally, the fastening waist-shaped holes are arranged in two rows along the length of the reinforcing strip, and the two rows of fastening waist-shaped holes are arranged alternately.

[0014] By adopting the above technical solution, the two rows of staggered fastening waist-shaped holes allow the fastening wedge to be inserted into the fastening waist-shaped holes at any bend, ensuring that the column formwork reinforcement unit can fasten column structures of any thickness and prevent the bend from falling exactly in the middle of a single row of fastening waist-shaped holes, thus improving the universality and adaptability of the column formwork reinforcement unit.

[0015] Optionally, the reinforcing strip is provided with reinforcing ribs along its length.

[0016] By adopting the above technical solution, the reinforcing ribs further enhance the strength of the reinforcing strips themselves, ensuring that when the reinforcing strips are pressed against the outside of the template, the clamping force of the reinforcing strips on the template is effectively improved, thus ensuring the flatness and quality of the template column surface.

[0017] This application also provides a column formwork reinforcement system. The technical solution adopted is as follows: A column formwork reinforcement system is used to install the above-mentioned column formwork reinforcement unit, comprising a plurality of the column formwork reinforcement units; It also includes four angle steels, which are located at the joint between the external corner plates of two adjacent templates; It also includes several fixing rods, which are fitted to the template, and four reinforcing strips press the angle steel and the fixing rods firmly onto the template.

[0018] By adopting the above technical solution, after the formwork is placed outside the reinforcing cage, angle steel is installed at the joint of the external corner of two adjacent formwork panels. Utilizing the structure of the angle steel itself, the verticality and flatness of the formwork are effectively guaranteed, preventing the formwork from tilting and directly affecting the load-bearing capacity of the cross-section column. At the same time, the angle steel seals the joint of the external corner of the formwork, effectively preventing concrete slurry from flowing out from the joint. The fixing rod ensures that the cross-section column is not uneven in the vertical direction, and further enhances the stability of the system, improving the verticality, flatness, and quality of the cross-section column. The angle steel, fixing rod, and column formwork reinforcement unit work together to enhance the clamping strength, making the system strong and stable in terms of clamping force. After processing, the cross-section column not only meets the standard requirements for flatness and verticality, but also effectively solves the problems of formwork bulging and slurry leakage.

[0019] Optionally, the template and the angle steel are provided with a covering film.

[0020] By adopting the above technical solution, the coating film completely seals the entire cross-section column. The coating film compresses the template and angle steel, further ensuring the fastening force and stability of the system and avoiding situations such as grout leakage.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. The reinforcing strips and fasteners are installed together on the outside of the formwork, eliminating the need for complex operations such as drilling. Installation is completed simply by pressing four reinforcing strips against the outside of the formwork using the fasteners. This simple and convenient operation increases installation efficiency. After use, the fasteners and reinforcing strips can be directly removed, facilitating installation and removal, and allowing for reuse. This avoids the problem of tie rods being fixed inside the cross-section column and unable to be removed, thus improving the utilization rate of the device. Simultaneously, the reinforcing strips are pulled close together on the outside of the formwork, preventing concentrated tightening force at the nut tightening points and avoiding single-point stress, thus preventing grout leakage in other parts of the cross-section column. The four reinforcing strips are pulled together, ensuring balanced force on the cross-section column in the plane of the reinforcing strips, resulting in a strong and stable fastening effect, preventing formwork bulging, deformation, and grout leakage, and ensuring... To ensure the quality of the formwork column, after the formwork is placed outside the reinforcing cage, angle steel is installed at the joint between the external corners of two adjacent formwork panels. Utilizing the angle steel's own structure, the verticality and flatness of the formwork are effectively guaranteed, preventing tilting that could directly affect the load-bearing capacity of the column. Simultaneously, the angle steel seals the joint between the external corners of the formwork, effectively preventing concrete slurry from leaking out. Fixing rods prevent unevenness in the vertical direction of the column, further enhancing the system's stability and improving the column's verticality, flatness, and overall quality. The angle steel, fixing rods, and column formwork reinforcement units work together to enhance clamping strength, resulting in a powerful and stable clamping force. After processing, the column not only meets the required flatness and verticality specifications but also effectively solves the problems of formwork bulging and slurry leakage.

[0022] 2. The bent portions of the four reinforcing strips are sequentially hooked to the end of another reinforcing strip furthest from the bend, forming a square ring that fits snugly onto the formwork. Then, a fastening wedge is inserted into the fastening slot, continuously pressing the reinforcing strips against the formwork. The structure of the fastening wedge increases the pressure between the wedge and the fastening slot when concrete is poured, enhancing the locking effect of the column formwork reinforcement unit and ensuring stable connection under vibration conditions, preventing structural failure. With two bends pointing upwards and two bends pointing downwards, the four reinforcing strips are subjected to stable force, ensuring the fastening force remains at the same level, resulting in stable fastening and enhanced connection reliability.

[0023] 3. The fastening wedge is inserted into the fastening waist-shaped hole to continuously press the four reinforcing strips against the template. The closer the fastening wedge is to the fastening waist-shaped hole, the tighter it becomes. The width of the widest part of the fastening wedge is greater than the length of the fastening waist-shaped hole, ensuring that the fastening wedge is always located in the fastening waist-shaped hole and always plays the role of pressing the reinforcing strip. This prevents the fastening wedge from falling directly out of the fastening waist-shaped hole and prevents the device from failing. The two rows of staggered fastening waist-shaped holes allow the fastening wedge to be inserted into the fastening waist-shaped holes at any bend. This ensures that the column template reinforcement unit can fasten column structures of any cross-section and prevents the bend from falling exactly in the middle of a single row of fastening waist-shaped holes, thus improving the versatility and adaptability of the column template reinforcement unit.

[0024] 4. The reinforcing ribs further enhance the strength of the reinforcing strips themselves, ensuring that when the reinforcing strips are pressed against the outside of the template, the clamping force of the reinforcing strips on the template is effectively increased, thus ensuring the flatness and quality of the template column surface.

[0025] 5. The covering film completely seals the entire cross-section column. The covering film compresses the formwork and angle steel, further ensuring the fastening force and stability of the system and preventing grout leakage. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0033] This application discloses a column formwork reinforcement unit.

[0034] like Figure 1 and Figure 2The column formwork reinforcement unit includes four reinforcing strips 1 and four fasteners 2. The four reinforcing strips 1 are connected sequentially by the four fasteners 2 to form a square structure. The fasteners 2 include a bend 21. One end of the reinforcing strip 1 is fixedly connected to the bend 21. The bend 21 is integrally formed with the reinforcing strip 1 and has a U-shaped structure. The bending length of the bend 21 is the same as the width of the reinforcing strip 1. The other end of the fastener 2 has a fastening waist-shaped hole 11. The length direction of the fastening waist-shaped hole 11 is consistent with the length direction of the fastener 2. Two rows of fastening waist-shaped holes 11 are opened along the length direction of the fastener 2, and the two rows of fastening waist-shaped holes 11 are arranged alternately. The bend 21 of the reinforcing strip 1 is hooked at the end of the reinforcing strip 1 near the end with the fastening waist-shaped hole 11. The four reinforcing strips 1 are hooked sequentially end to end. The bends 21 of two adjacent reinforcing strips 1 are hooked in opposite directions, and the bends 21 of two opposite reinforcing strips 1 are hooked in the same direction. The fastener 2 also includes a fastening wedge 22, which is a triangular plate structure. The fastening wedge 22 passes through the fastening waist-shaped hole 11 at the connection between the reinforcing strip 1 and the bend 21. The fastening wedge 22 passes through the fastening waist-shaped hole 11 outside the square structure formed by the four reinforcing strips 1. The fastening wedge 22 presses the four reinforcing strips 1 tightly around the outside of the template. The length of the fastening waist-shaped hole 11 is less than the width of the widest part of the fastening wedge 22, and the width of the fastening waist-shaped hole 11 is slightly greater than the thickness of the fastening wedge 22. Reinforcing ribs are fixedly provided on both sides of the reinforcing strip 1 along the length direction. The reinforcing ribs are located at the top two edges of the reinforcing strip 1 and are integrally formed with the reinforcing strip 1.

[0035] In other embodiments, the fastener 2 may also have one or three rows of other fastening waist-shaped holes 11, the bends 21 of the four reinforcing strips 1 may all face the same side, and the reinforcing strips 1 may have three or four other reinforcing ribs, which may be perpendicular or intersecting each other.

[0036] This application also discloses a column formwork reinforcement system.

[0037] like Figure 3 , Figure 4 and Figure 5The column formwork reinforcement system includes four angle steels 31, which are located at the seams of the external corner plates of two adjacent formworks. The angle steels 31 are L30*3 angle steels 31. After the column formwork is positioned by the chalk line, a covering film 33 is set around the formwork and the angle steels 31. It also includes several fixing rods 32. The length direction of the fixing rods 32 is the same as the length direction of the formwork. The length of the fixing rods 32 is the same as the length of the formwork. The fixing rods 32 are set close to the formwork. The fixing rods 32 on the same formwork surface are all equidistantly set. Several sets of the above-mentioned column formwork reinforcement units are fixedly set on the outside of the fixing rods 32. The column formwork reinforcement units are set 150mm from the ground. The sets of column formwork reinforcement units are equidistant from each other. The distance between two adjacent formwork reinforcement units is 300mm. Four reinforcing strips 1 press the angle steels 31 and the fixing rods 32 tightly onto the formwork. The side wall of the reinforcing strip 1 facing the fixing rod 32 is close to the fixing rod 32. The inner wall of the bent fold 21 is close to the side wall of the adjacent reinforcing strip 1 away from the fixing rod 32.

[0038] In other embodiments, angle steel 31 can be of other specifications, the distance between fixing rods 32 can be arranged arbitrarily, and several sets of column template reinforcing units can be arranged arbitrarily.

[0039] The implementation principle of this application embodiment is as follows: The reinforcing strips 1 and fixing members 2 are installed together around the outside of the template. No complex operations such as drilling or penetration are required. Installation is completed simply by pressing the four reinforcing strips 1 against the outside of the template using the fixing members 2. The operation is simple and convenient, with higher installation efficiency. After use, the fixing members 2 and reinforcing strips 1 can be directly removed, facilitating installation and removal, and allowing for reuse. This avoids the problem of tie rods being fixed inside the cross-section column and unable to be removed, thus improving the utilization rate of the device. Simultaneously, the reinforcing strips 1 are pulled close together on the outside of the template, preventing concentrated tightening force at the nut tightening points and avoiding single-point stress, thus preventing grout leakage in other parts of the cross-section column. The mutual tightening of the four reinforcing strips 1 ensures balanced force on the cross-section column in the plane where the reinforcing strips 1 are located, resulting in a strong and stable tightening effect, preventing template bulging, deformation, and grout leakage. To ensure the quality of the formwork column, after the formwork is placed outside the reinforcing cage, angle steel 31 is installed at the corner joints of two adjacent formwork panels. Utilizing the structure of angle steel 31, the verticality and flatness of the formwork are effectively guaranteed, preventing tilting that could directly affect the load-bearing capacity of the column. Simultaneously, angle steel 31 seals the corner joints of the formwork, effectively preventing concrete grout from leaking out. Fixing rod 32 ensures the column remains vertically level, further enhancing the system's stability and improving the column's verticality, flatness, and quality. The angle steel 31, fixing rod 32, and column formwork reinforcement unit work together to enhance clamping strength, resulting in a powerful and stable clamping force. After processing, the column not only meets the required flatness and verticality specifications but also effectively solves the problems of formwork bulging and grout leakage.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
