Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building construction technology, and in particular relates to a screwless reinforcement device for structural beam formwork. Background Technology
[0002] Existing structural beam formwork reinforcement systems typically employ tie bolts and timber for fixing, requiring drilling into the formwork to install the tie bolts. However, this method is unsuitable for structural beams with specific requirements, such as civil defense structural beams and steel structural beams. Civil defense structural beam construction requirements prohibit openings for reinforcement measures such as threaded rods. In steel structural beam construction, the presence of steel components in the middle of the beam makes it impossible to effectively reinforce the formwork with threaded rods. On-site, tie bolts are often welded to the steel components. Therefore, in both civil defense and steel structural beam construction, the tie bolts are embedded in the concrete. After formwork removal, the exposed portions of the tie bolts need to be cut, rust-proofed, and leveled. This not only results in unsightly finishes but also increases the workload and construction costs of subsequent treatments. Furthermore, the tie bolts embedded in the concrete can pose a quality hazard, affecting structural safety. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model provides a screwless reinforcement device for structural beam formwork, which solves the problem that the existing structural beam formwork reinforcement system requires post-cutting, rust prevention and leveling treatment when using tie bolts.

[0006] Furthermore, the side support includes the adjustment mechanism and the reinforcing member.

[0024] The embodiments of this utility model will now be described with reference to the accompanying drawings.
[0025] This utility model provides a bolt-free reinforcement device for structural beam formwork, used to reinforce the formwork of structural beams during building construction. This eliminates the need for additional tie bolt reinforcement, ensuring the construction quality of the structural beams. This is particularly beneficial for structural beams with specific requirements, such as civil defense structural beams and steel structural beams. It not only avoids leaving tie bolts embedded in the concrete, eliminating the need for cutting, rust prevention, and leveling of exposed tie bolts, but also ensures structural safety, improves construction efficiency, and reduces construction costs.
[0026] like Figures 1 to 4 As shown in the figure, this utility model embodiment proposes a screwless reinforcement device for structural beam formwork, including side support members, bottom support members, vertical reinforcement members 7, and diagonal bracing members; the following is a detailed description of each part:
[0027] Two side supports are arranged opposite each other to reinforce the side formwork of the structural beam;
[0028] The bottom support is connected to the bottom end of the side support and is used to reinforce the bottom formwork of the structural beam;
[0029] The bottom support has extension sections 31 at both ends, which are located on the outside of the side support. The adjacent ends of the vertical reinforcement 7 are fixed to the side support and the bottom support, respectively. The extension section 31 and the vertical reinforcement 7 are respectively provided with limiting grooves 5, and the two ends of the diagonal brace reinforcement are inserted into the limiting grooves 5.
[0030] The aforementioned bottom support member connects with the two side support members to form a U-shaped structure. The cavity in this U-shaped structure is adapted to the formwork used for shaping the structural beam. Typically, the formwork for a structural beam includes a bottom formwork and two side formworks. The bottom and side formworks include wooden beams set on the outside of the formwork body. By setting several bottom and side support members along the length of the structural beam, effective support can be provided to the structural beam formwork to prevent the bottom and side formworks from moving or deforming under the weight and lateral pressure of the concrete. The vertical reinforcement member 7 improves the integrity and stability of the bottom and side support members, better preventing deformation of the bottom and side support members themselves, and effectively ensuring that they fully play their supporting role for the structural beam formwork. By setting extension sections 31 at both ends of the bottom support member, an installation base is provided for the diagonal bracing reinforcement member, allowing the diagonal bracing reinforcement member to be connected to the bottom support member and the vertical reinforcement member 7 as a whole. This forms a triangular support structure, further improving the stability and deformation resistance of the bottom and side supports, thus ensuring the stable connection and reliable support of the overall structure. Through the above technical solution, vertical reinforcement members 7 and diagonal bracing are used to strengthen the bottom and side supports multiple times, ensuring their integrity and stability. This replaces the tie rods in traditional formwork reinforcement systems, especially enabling the side supports to meet the requirements of resisting lateral pressure during concrete pouring, ensuring the reinforcement performance and stability of the structural beam formwork. Furthermore, the above device can be completely removed after the structural beam construction is completed, leaving the concrete surface with excellent appearance quality. This eliminates the need for cutting, rust prevention, and leveling of exposed tie bolts in traditional methods, saving significant time and effort. Additionally, the device can be moved elsewhere for reuse after dismantling, reducing construction costs.
[0031] Furthermore, in the embodiments of this application, such as Figure 1As shown, the bottom support also includes a fixing member 3 and an adjustment mechanism. The fixing member 3 is connected to the side support, and the adjustment mechanism is located between the two fixing members 3 to adjust the distance between them. The extension section 31 is located at the other end of the fixing member 3. By setting the adjustment mechanism, the distance between the two fixing members 3 can be adjusted according to the width of different structural beams, thereby adjusting the distance of the side support to adapt to structural beams of different widths for repeated use. At the same time, this setting allows the side support to clamp the side formwork of the structural beam when the device is installed on the outside of the wooden beam of the structural beam template, ensuring effective support of the side support for the side formwork. This makes the installation and adjustment of the device more convenient and efficient.
[0032] Similarly, in the embodiments of this application, such as Figure 1 As shown, the side support includes an adjustment mechanism and reinforcing members 6. The adjustment mechanism is located between the two reinforcing members 6 and is used to adjust the distance between them. The lower reinforcing member 6 is connected to the fixing member 3. By setting the adjustment mechanism on the side support, the length of the side support in the vertical direction can be adjusted according to the height of the structural beam, so that the device can be adapted to structural beams of different heights for repeated use. At the same time, by connecting the lower reinforcing member 6 to the fixing member 3, the side support and the bottom support can be connected as a whole before the device is used, and then the whole device can be installed on the outside of the wooden beam of the structural beam formwork. The adjustment mechanism makes the bottom support abut against the bottom formwork of the structural beam, ensuring effective support of the bottom support for the bottom formwork, and making the installation and adjustment of the device more convenient and efficient.
[0033] In this application, the function of the adjustment mechanism is to adjust the length of the side support or the bottom support so that the distance between the two side supports is adapted to the width of the structural beam and the length of the side support is adapted to the height of the structural beam. Therefore, in practical applications, the adjustment mechanism can adopt any structural form that can achieve the above-mentioned technical effects.
[0034] In this embodiment, a preferred structural form of the adjustment mechanism is proposed: the adjustment mechanism includes an adjusting member 2 and a connecting member 1; the connecting member 1 is symmetrically arranged at both ends of the adjusting member 2, and the connecting member 1 is threadedly connected to the fixing member 3 and / or the reinforcing member 6. Specifically, one end of the fixing member 3 and the reinforcing member 6 is provided with a cavity with internal threads, the two connecting members 1 are of the same length, and both ends are provided with opposite external threads, which are connected to the fixing member 3 or the reinforcing member 6 through the external threads, so that the connecting member 1 is inserted into the cavity of the fixing member 3 or the reinforcing member 6; by rotating the adjusting member 2, the length of the two connecting members 1 extending into the inside of the fixing member 3 or the reinforcing member 6 can be adjusted simultaneously, thereby controlling the overall length of the side support and the bottom support, and finally realizing the adjustment of the spacing and length of the two side support members; the overall structure is simple and easy to operate, the threaded connection realizes continuous and precise adjustment of the length, and at the same time, the connecting member 1 can be fixed to the fixing member 3 or the reinforcing member 6 by the thread self-locking method, so as to avoid the connecting member 1 from moving or rotating during use, thus ensuring the stability of the adjustment mechanism.
[0035] In one specific embodiment, the bottom support adopts the aforementioned adjustment mechanism. One end of the connector 1 is connected to the adjustment component 2, and the other end is threadedly connected to the fixing component 3. It is understood that the length adjustment range of the bottom support depends on the length of the connector 1 that can be inserted into the fixing component 3. During use, the length of the connector 1 extending into the fixing component 3 is initially adjusted according to the width of the structural beam, and then finely adjusted using the adjustment component 2. This two-stage adjustment mechanism ensures that the bottom support can accurately match the width of the structural beam, improving the stability and reliability of the reinforcement device. Furthermore, this design makes the adjustment process more flexible and precise, allowing construction personnel to complete the installation and adjustment of the bottom support more quickly, reducing rework and modification time due to size mismatch, and lowering construction difficulty. Additionally, this design enables a detachable connection between the adjustment mechanism and the fixing component 3, allowing for replacement and maintenance of the adjustment mechanism according to usage requirements, and facilitating the disassembly of the entire device into smaller components, which is beneficial for the transport and classified storage of the device.
[0036] Furthermore, in the above embodiment, the side wall of the adjusting member 2 is provided with an adjusting hole 21, and a rotating member 11 is inserted into the adjusting hole. The rotating member 11 includes a rod-shaped component. By passing the rotating member 11 through the adjusting hole 21, the rod-shaped component is perpendicular to the axial direction of the adjusting member 2. The adjusting member 2 can be rotated by the rotating member, thereby achieving precise adjustment of the length of the bottom support or the side support.
[0037] It is understood that, in this application, the aforementioned adjustment mechanism can be used for the bottom support, the side support, or both the bottom support and the side support, without any limitation.
[0038] Furthermore, in the above embodiment, the vertical reinforcing member 7 includes an upper reinforcing section and a lower reinforcing section. The upper reinforcing section is fixed to the reinforcing member 6 above the adjustment mechanism, and the lower reinforcing section is fixed to the reinforcing member 6 and the fixing member 3 below the adjustment mechanism. The ends of the upper and lower reinforcing sections away from the adjustment mechanism are widened. The vertical reinforcing member 7 is used to improve the strength of the side support and the integrity and stability between the side support and the bottom support. By splitting the reinforcing member 6 into an upper reinforcing section and a lower reinforcing section, the reinforcing member 6 is prevented from affecting the operation of the adjustment mechanism. Since the end of the upper reinforcing section away from the adjustment mechanism is the top of the vertical reinforcing member 7, it is a free end and therefore experiences a greater bending moment load, making it prone to deformation. Therefore, this end is widened. At the same time, the bottom end of the lower reinforcing section is the weak link between the side support and the bottom support. By widening this end, the stability of the connection between the two is improved.
[0039] In one specific embodiment, the aforementioned reinforcing member 6 is made of a steel plate with a set thickness, the thickness direction of the steel plate is set along the length direction of the structural beam, and the top of the upper reinforcing member 6 is widened; the lower reinforcing member 6 is a trapezoidal plate, and adopts a form that gradually widens from top to bottom, which can adapt to the stress characteristics of the lower reinforcing member 6 and achieve a better reinforcing effect.
[0040] Furthermore, in the embodiments of this application, such as Figure 1 , Figure 3 As shown, the screwless reinforcement device for structural beam formwork proposed in this application also includes a tensioning member 8; the upper and lower reinforcing sections are provided with connecting holes 71, the axis of which is arranged along the length of the structural beam, and both ends of the tensioning member 8 are fixed to the connecting holes 71 by fasteners. By setting the tensioning member 8, the upper and lower reinforcing sections are connected as one unit, enhancing the stability of the vertical reinforcing member 7 and ensuring the support and reinforcement effect of the vertical reinforcing member 7 on the side support members.
[0041] like Figure 1 As shown, in a specific technical solution of the above embodiment, the connecting hole 71 penetrates the thickness of the upper and lower reinforcing sections to form a through hole; the tie member is made of steel plate, and an elongated connecting groove is provided in the length direction of the steel plate, which can be fixed to the connecting hole 71 by fasteners passing through the connecting groove. At the same time, the setting of the connecting groove allows the tie member to adapt to the spacing between different connecting holes 71, and its position can be vertically adjusted as needed.
[0042] Furthermore, such as Figure 4As shown, the diagonal brace reinforcement includes a telescopic mechanism, which includes a telescopic sleeve 9 and a telescopic rod 10. The telescopic rod 10 is threaded to both ends of the telescopic sleeve 9, and the other end of the telescopic rod 10 is provided with a connector adapted to the limiting groove 5. Specifically, the telescopic sleeve 9 is a tube with a hollow cavity and openings at both ends, and is provided with an adjustment hole 21 for inserting the rotating part 11. The telescopic sleeve 9 is provided with an internal thread, and one end of each of the two telescopic rods 10 is provided with a matching external thread. The connector at one end of the diagonal brace reinforcement is inserted into the limiting groove 5 on the extension section 31 of the reinforcement, and the connector at the other end can be inserted into the limiting groove 5 on the upper vertical reinforcement 7. By setting the telescopic mechanism, on the one hand, the length of the diagonal brace reinforcement can be adapted to side support members of different lengths. On the other hand, after the diagonal brace reinforcement is initially inserted into the limiting groove 5, the telescopic mechanism can control the extension of the diagonal brace reinforcement so that the connector abuts against the two limiting grooves 5 respectively, realizing convenient installation of the diagonal brace reinforcement and ensuring the support effect of the diagonal brace reinforcement on the vertical reinforcement 7.
[0043] In the above embodiments, the vertical reinforcement 7 includes an upper reinforcement section and a lower reinforcement section. A limiting groove 5 can be provided on the upper reinforcement section or on the lower reinforcement section. Preferably, a limiting groove 5 is provided on the upper reinforcement section to improve the support effect of the diagonal brace reinforcement.
[0044] Furthermore, a top support limiting member 4 is provided at the bottom of the extension section 31 to limit the position of the vertical support to be installed at the bottom of the bottom support member. Normally, the bottom of the structural beam formwork is supported by a support system to resist the weight load of the structural beam itself. This support system includes several interconnected vertical supports, horizontal braces, and horizontal longitudinal braces. The top of each vertical support is provided with a top support, and a steel pipe is installed inside the top support. The steel pipe is in direct contact with the bottom timber of the structural beam to achieve vertical load transfer. In this application, the reinforcing parts are symmetrically arranged relative to the adjustment mechanism, and the connecting part 1 is symmetrically arranged relative to the adjusting part 2, ensuring that the center of the adjusting part 2 is always aligned with the centerline of the structural beam during adjustment and use. A top support limiting member 4 is provided at the bottom of the extension section 31, and the top support limiting member 4 is also symmetrically arranged relative to the center of the adjusting part 2. This ensures that the bottom support member receives a balanced vertical support force, and also limits the displacement of the bottom support member and side support members by the vertical support, further improving the overall structural stability.
[0045] Furthermore, the limiting groove 5 of the extension section 31 is set at the corresponding position of the top support limiting member 4. Through this setting, the vertical support can provide reinforced support for the diagonal brace reinforcement member.
[0046] This application proposes a reinforcement method using the above-mentioned screwless reinforcement device for structural beam formwork, including the following steps:
[0047] S1. Fix the two side supports of the screwless reinforcement device for the structural beam formwork to the bottom support, and adjust the length and spacing of the side supports according to the width and height of the structural beam and fix them initially.
[0048] In one specific embodiment, the bottom support includes a fixing member 3 and an adjustment mechanism, the adjustment mechanism including an adjustment member 2 and a connecting member 1; wherein, the fixing member 3 is made of a square steel tube with a circular cavity at one end; the adjustment member 2 is made of a solid cuboid steel material; and the connecting member 1 is made of a steel rod.
[0049] The side support includes a reinforcing member 6 and an adjusting mechanism, which includes an adjusting member 2 and a connecting member 1. The reinforcing member 6 is made of a square steel tube with a circular cavity at one end; the adjusting member 2 is made of a solid cuboid steel; and the connecting member 1 is made of a steel rod.
[0050] Specifically, when determining the spacing of the side supports, the width and height of the structural beam and the thickness of the side formwork of the structural beam should be considered simultaneously, so that the spacing of the side supports is slightly greater than the sum of the two; at the same time, when determining the length of the side supports, it should be slightly greater than the height of the structural beam, so as to facilitate the initial installation of the screwless reinforcement device for the structural beam formwork on the outside of the wooden beam of the structural beam formwork, and to reserve adjustment space.
[0051] In this step, the upper and lower reinforcing sections of the vertical reinforcing member 7 have been welded to the reinforcing member 6 of the side support member. The upper reinforcing section is set to the same length as the reinforcing member 6 above the adjustment mechanism, and the lower reinforcing section is set to the same length as the reinforcing member 6 below the adjustment mechanism. The vertical reinforcing members 7 are made of steel plates and have connecting holes 71 that penetrate their thickness.
[0052] S2. Place the pre-fixed structural beam formwork reinforcement device without screws on the outside of the bottom and side formwork of the installed structural beam;
[0053] Specifically, during installation, try to set the two side support members symmetrically on the side formwork of the structural beam, and make the bottom support members fit as closely as possible to the bottom support members;
[0054] S3. Adjust the length of the bottom support to make the side support clamp the side template; adjust the length of the side support to make the bottom support abut against the bottom template.
[0055] Specifically, the rotating part 11 is inserted into the adjusting hole 21 on the adjusting part 2, and the rotating part 11 is turned so that the connecting part 1 continuously extends into the fixing part 3 or the reinforcing part 6, thereby driving the side support parts to move closer to each other and clamp the side formwork of the structural beam, and driving the bottom support parts to move upward to push against the bottom formwork of the structural beam.
[0056] S4. Install tensioning member 8 to fix the upper and lower reinforcing sections on the side support member.
[0057] In this embodiment, the tensioning member 8 is made of a steel plate with a connecting groove in the middle, and is fixed to the connecting hole 71 of the upper and lower reinforcing sections by fasteners passing through the connecting groove; the fasteners are bolts and nuts.
[0058] S5. Erect a beam bottom formwork support system so that the top support is locked in the top support limiting member 4 at the bottom of the bottom support extension section 31, and the support rods at the bottom of the top support are symmetrically arranged below the screwless reinforcement device of the structural beam formwork.
[0059] Specifically, when erecting vertical supports, the top support is inserted into the top support limiting piece 4 and a steel pipe is added to form effective support for the bottom support piece.
[0060] S6. Install the diagonal brace reinforcement and adjust the length of the diagonal brace reinforcement so that its two ends abut against the vertical reinforcement 7 and the extension section 31 respectively;
[0061] The length of the diagonal brace reinforcement is initially set according to the distance between the two limiting grooves 5, so that the connectors at both ends can be inserted into the limiting grooves 5. Then, the diagonal brace reinforcement is extended by the adjustment mechanism so that the connectors abut against the two limiting grooves 5 respectively.
[0062] S7. Sequentially complete the installation of screwless reinforcement devices for all structural beam formwork along the length of the structural beam.
[0063] Specifically, the number, location, and installation sequence of the screwless reinforcement devices for structural beam formwork are determined based on the stress calculations of the structural beam.
[0064] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made in accordance with the claims of this utility model should still fall within the patent coverage of this utility model.
