[0002] The existing structural beam formwork reinforcement system usually adopts tension bolts and wooden squares for reinforcement. During reinforcement, holes need to be punched in the formwork to install tension bolts. However, the above method is not applicable to structural beams with specific requirements, such as civil air defense structural beams and steel structural beams. The construction requirements of civil air defense structural beams do not allow the existence of holes for rod reinforcement construction measures such as screw rods. During the construction of steel structural beams, due to the influence of the steel structure in the middle of the beam, it is impossible to effectively reinforce the structural beam formwork with screw rods. The site often adopts the method of welding tension bolts to the steel structure. Therefore, during the construction of civil air defense structural beams and steel structural beams, the tension bolts are cast in the concrete.

[0032] The embodiments of the present invention are described below with reference to the accompanying drawings.

[0033] An embodiment of the present invention proposes a screw-free reinforcement device for structural beam formwork, which is used to reinforce the formwork of structural beams during construction, so that the beam formwork does not need to be additionally reinforced with tension bolts, thereby ensuring the construction quality of the structural beams, especially structural beams with specific requirements such as civil air defense structural beams and steel structural beams. It not only avoids leaving the tension bolts in the concrete, but also eliminates the operations of cutting, rust-proofing and leveling the exposed parts of the tension bolts, but also ensures the safety of the structure, improves construction efficiency and reduces construction costs.

[0034] like Figures 1 to 4 As shown, the embodiment of the present invention proposes a screw-free reinforcement device for a structural beam template, including side support members, bottom support members, vertical reinforcement members 7 and diagonal bracing reinforcement members; each part is described in detail below:

[0035] Two side supports are arranged opposite to each other to reinforce the side formwork of the structural beam;

[0036] The bottom support member is connected to the bottom end of the side support member and is used to reinforce the bottom formwork of the structural beam;

[0037] Among them, the bottom support member is provided with an extension section 31 at the opposite ends, the extension section 31 is arranged on the outside of the side support member, and the adjacent two ends of the vertical reinforcement member 7 are respectively fixed to the side support member and the bottom support member; the extension section 31 and the vertical reinforcement member 7 are respectively provided with a limiting groove 5, and the two ends of the diagonal support reinforcement member are inserted into the limiting groove 5.

[0038] The above-mentioned bottom support is connected with the two side support members to form a U-shaped structure. The cavity in the U-shaped structure is adapted to the formwork for shaping the structural beam. Usually, the formwork of the structural beam includes a bottom formwork and two side formworks. The bottom formwork and the side formwork include wooden beams arranged on the outside of the formwork body. By arranging a number of bottom support members and side support members in the length direction of the structural beam, effective support can be provided to the structural beam formwork to prevent the bottom formwork and the side formwork from moving or deforming under the action of concrete gravity and lateral pressure; and the vertical reinforcement 7 is provided to improve the integrity and stability of the bottom support and the side support, which can better prevent the bottom support and the side support themselves from deformation, and effectively ensure that the two fully play their supporting role on the structural beam formwork; by arranging extension sections 31 at both ends of the bottom support, an installation basis is provided for the arrangement of the diagonal bracing reinforcement, so that the diagonal bracing reinforcement is connected to the bottom support and the vertical reinforcement 7 as a whole. , forming a triangular support structure, thereby further improving the stability and deformation resistance of the bottom support and side support, thereby ensuring the stable connection and reliable support of the overall structure; through the above technical solution, vertical reinforcement members 7 and diagonal bracing reinforcement members are used to perform multiple reinforcements on the bottom support and side support, thereby ensuring the integrity and stability of the bottom support and side support, replacing the tension screws in the traditional formwork reinforcement system, especially enabling the side support members to meet the requirements of resisting the lateral pressure during concrete pouring, ensuring the reinforcement performance and stability of the structural beam formwork; and the above-mentioned device can be completely removed after the construction of the structural beam is completed, and the concrete on the surface of the structural beam has a good visual quality, eliminating the work of cutting, rust-proofing and leveling the exposed part of the tension bolts in the traditional method, saving a lot of working time and workload; in addition, after the device is dismantled, it can be moved to another place for turnover, reducing construction costs.

[0039] Furthermore, in the embodiments of the present application, Figure 1 As shown, the bottom support member also includes a fixing member 3 and an adjustment mechanism. The fixing member 3 is connected to the side support member. The adjustment mechanism is provided between the two fixing members 3 and is used to adjust the distance between the fixing members 3. An extension section 31 is provided at the other end of the fixing member 3. By providing the adjustment mechanism, the distance between the two fixing members 3 can be adjusted according to the width of different structural beams, and the distance between the side supports can be adjusted, so that it can be adapted to the turnover of structural beams of different widths. At the same time, through this arrangement, when the device is installed on the outside of the wooden beam of the structural beam formwork, the adjustment mechanism can be used to clamp the side support members to the side formwork of the structural beam, ensuring that the side support members effectively support the side formwork, making the installation and adjustment of the device more convenient and efficient.

[0040] Likewise, in the embodiments of the present application, Figure 1As shown, the side support members include an adjustment mechanism and a reinforcement member 6. The adjustment mechanism is provided between the two reinforcement members 6 and is used to adjust the distance between the reinforcement members 6. The reinforcement member 6 located at the bottom is connected to the fixing member 3. By providing the adjustment mechanism on the side support members, the vertical length of the side support members can be adjusted according to the height of the structural beam, so that the device can be adapted for the turnover of structural beams of different heights. At the same time, by connecting the lower reinforcement member 6 to the fixing member 3, the side support members and the bottom support members can be connected together before the device is used, and then the whole can be installed on the outside of the wooden beam of the structural beam formwork. The adjustment mechanism can be used to make the bottom support member press against the bottom formwork of the structural beam, ensuring that the bottom support member effectively supports the bottom formwork and making the installation and adjustment of the device more convenient and efficient.

[0041] In this application, the function of the adjustment mechanism is to adjust the length of the side support member or the bottom support member so that the distance between the two side support members is adapted to the width of the structural beam, and the length of the side support member is adapted to the height of the structural beam. Therefore, in actual application, the adjustment mechanism can adopt any structural form that can achieve the above-mentioned technical effects.

[0042] In an embodiment of the present application, a preferred structural form of an adjustment mechanism is proposed: the adjustment mechanism includes an adjustment member 2 and a connector 1; the connector 1 is symmetrically arranged at both ends of the adjustment member 2, and the connector 1 is connected to the fixed member 3 and / or the connector 1 is connected to the reinforcement member 6 by a thread. Specifically, one end of the fixed member 3 and the reinforcement member 6 is provided with a cavity with an internal thread. The two connectors 1 are of the same length and have opposite external threads at both ends. The external threads connect the connectors 1 to the fixed member 3 or the reinforcement member 6, so that the connector 1 is inserted into the cavity of the fixed member 3 or the reinforcement member 6. By rotating the adjustment member 2, the length of the two connectors 1 extending into the inner side of the fixed member 3 or the reinforcement member 6 can be synchronously adjusted, thereby controlling the overall length of the side support member and the bottom support member, and ultimately adjusting the spacing and length of the two side supports. The overall structure is simple and easy to operate. The threaded connection method realizes continuous and precise adjustment of the length. At the same time, the threaded connection method can be used to fix the connector 1 to the fixed member 3 or the reinforcement member 6 by self-locking, so as to prevent the connector 1 from moving or rotating during use, thereby ensuring the stability of the adjustment mechanism.

[0043] In a specific embodiment, the bottom support member adopts the above-mentioned adjustment mechanism, one end of the connecting member 1 is connected to the adjusting member 2, and the other end is threadedly connected to the fixing member 3; it can be understood that the length adjustment range of the bottom support member depends on the length of the connecting member 1 that can be inserted into the inner side of the fixing member 3. When in use, the length of the connecting member 1 extending into the fixing member 3 is preliminarily adjusted according to the width of the structural beam, and then fine-tuned through the adjusting member 2. This two-level adjustment mechanism ensures that the bottom support member can accurately match the width of the structural beam, thereby improving the stability and reliability of the reinforcement device; in addition, this setting also makes the adjustment process more flexible and accurate, and construction personnel can complete the installation and adjustment of the bottom support member more quickly, reducing the rework and modification time caused by size mismatch, and reducing the construction difficulty; in addition, this setting can realize a detachable connection between the adjustment mechanism and the fixing member 3, which not only allows the adjustment mechanism to be replaced and maintained according to use requirements, but also makes it easier to disassemble the entire device into smaller components, which is conducive to the transportation and classified storage of the device.

[0044] Furthermore, in the above embodiment, an adjustment hole 21 is provided on the side wall of the adjustment member 2, and a rotating member 11 is inserted into the adjustment hole. The rotating member 11 includes a rod-shaped component. By passing the rotating member 11 through the adjustment hole 21, the rod-shaped component is perpendicular to the axial direction of the adjustment member 2, and the adjustment member 2 can be driven to rotate by the rod rotating component, thereby realizing precise adjustment of the length of the bottom support member or the side support member.

[0045] It is understandable that, in the present application, the above-mentioned adjustment mechanism can be used for the bottom support member, can also be used for the side support member, or can be used for the bottom support member and the side support member at the same time, and there is no limitation here.

[0046] Furthermore, in the above embodiment, the vertical reinforcement 7 includes an upper reinforcement section and a lower reinforcement section. The upper reinforcement section is fixed to the reinforcement 6 above the adjustment mechanism, and the lower reinforcement section is fixed to the reinforcement 6 and the fixing member 3 below the adjustment mechanism. The upper and lower reinforcement sections are widened at the ends away from the adjustment mechanism. The vertical reinforcement 7 is used to improve the strength of the side support member and the integrity and stability between the side support member and the bottom support member. By splitting the reinforcement 6 into the upper and lower reinforcement sections, the reinforcement 6 is prevented from affecting the operation of the adjustment mechanism. Since the end of the upper reinforcement section away from the adjustment mechanism is the top of the vertical reinforcement 7, it is a free end and is therefore subject to increased bending moment load, making it very prone to deformation. Therefore, this end is widened. At the same time, the bottom end of the lower reinforcement section is the weak link in the connection between the side support member and the bottom support member. By widening this end, the stability of the connection between the two is improved.

[0047] In a specific embodiment, the above-mentioned reinforcement 6 is made of a steel plate with a set thickness, the thickness direction of the steel plate is arranged along the length direction of the structural beam, and the top of the upper reinforcement 6 is widened; the lower reinforcement 6 is a trapezoidal plate, and is gradually widened from top to bottom, which can adapt to the force characteristics of the lower reinforcement 6 and achieve a better reinforcement effect.

[0048] Furthermore, in the embodiments of the present application, Figure 1 、 Figure 3 As shown, the screw-free reinforcement device for structural beam formwork proposed in this application also includes a tensioning member 8; the upper and lower reinforcement sections are provided with connecting holes 71, the axes of which are arranged along the length of the structural beam, and the ends of the tensioning member 8 are fixed to the connecting holes 71 by fasteners. By providing the tensioning member 8, the upper and lower reinforcement sections are connected as a whole, thereby enhancing the stability of the vertical reinforcement member 7 and ensuring the supporting and reinforcing effect of the vertical reinforcement member 7 on the side support members.

[0049] like Figure 1 As shown, in a specific technical solution of the above embodiment, the connection hole 71 passes through the thickness of the upper reinforcement section and the lower reinforcement section to form a through hole; the anchor is made of steel plate, and an elongated connection groove is opened in the length direction of the steel plate, which can be fixed to the connection hole 71 through a fastener passing through the connection groove. At the same time, the setting of the connection groove enables the anchor to adapt to the spacing between different connection holes 71, and its position can be adjusted vertically as needed.

[0050] Furthermore, if Figure 4 As 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 threadedly connected to both ends of the telescopic sleeve 9, and the other end of the telescopic rod 10 is provided with a connector that is compatible with the limit groove 5; specifically, the telescopic sleeve 9 is a tubular with a hollow cavity and openings at both ends, and is provided with an adjustment hole 21 for inserting a rotating member 11. The telescopic sleeve 9 is provided with an internal thread, and one end 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 limit groove 5 on the reinforcement extension section 31, and the connector at the other end can be inserted into the limit 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 supports of different lengths. On the other hand, after the diagonal brace reinforcement is initially inserted into the limit groove 5, the telescopic mechanism can be used to control the extension of the diagonal brace reinforcement so that the connectors respectively push against the two limit grooves 5, thereby realizing convenient installation of the diagonal brace reinforcement and ensuring the supporting effect of the diagonal brace reinforcement on the vertical reinforcement 7.

[0051] In the above embodiment, the vertical reinforcement 7 includes an upper reinforcement section and a lower reinforcement section. A limiting groove 5 can be set on the upper reinforcement section, or a limiting groove 5 can be set on the lower reinforcement section; preferably, a limiting groove 5 is set on the upper reinforcement section to improve the supporting effect of the diagonal bracing reinforcement.

[0052] Furthermore, a top support limiter 4 is provided at the bottom end 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 template is supported by a support system to resist the gravity load of the structural beam itself; the support system includes a number of interconnected vertical supports, horizontal cross braces and horizontal longitudinal braces, wherein a top support is provided at the top of the vertical support, and a steel pipe is provided inside the top support, which is in direct contact with the wooden beam at the bottom of the structural beam to achieve vertical load transfer; in the present application, the reinforcement is symmetrically arranged relative to the adjustment mechanism, and the connecting member 1 is symmetrically arranged relative to the adjustment member 2, so that the center of the adjustment member 2 is always aligned with the center line of the structural beam during adjustment and use. A top support limiter 4 is provided at the bottom of the extension section 31, and the top support limiter 4 is also symmetrically arranged relative to the center of the adjustment member 2, ensuring that the bottom support member is supported by a balanced vertical support force. At the same time, the displacement of the bottom support member and the side support member can be limited by the setting of the vertical support, further improving the stability of the overall structure.

[0053] Furthermore, the limiting groove 5 of the extension section 31 is arranged at a corresponding position of the supporting limiting member 4. Through this arrangement, the vertical support can provide enhanced support for the diagonal support reinforcement member.

[0054] The present application also proposes a method for reinforcing a structural beam formwork without screws, which uses the above-mentioned structural beam formwork without screw reinforcement device, including the following steps:

[0055] S1. Fix the two side supports of the screw-free 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 preliminarily fix them;

[0057] The side support member includes a reinforcement member 6 and an adjustment mechanism, and the adjustment mechanism includes an adjustment member 2 and a connector 1; wherein the reinforcement member 6 is made of a steel square tube with a circular cavity at one end; the adjustment member 2 is made of a solid square steel material; and the connector 1 is made of a steel rod.

[0058] Specifically, when determining the spacing of the side supports, the width and height of the structural beam and the thickness of the structural beam side formwork should be taken into consideration simultaneously, so that the spacing of the side supports is slightly larger than the sum of the two. At the same time, when determining the length of the side supports, it should be slightly larger than the height of the structural beam, so that the screw-free reinforcement device for the structural beam formwork can be initially installed on the outside of the wooden beam of the structural beam formwork and space for adjustment can be reserved.

[0059] In this step, the upper reinforcement section and the lower reinforcement section of the vertical reinforcement 7 have been previously welded to the reinforcement 6 of the side support member. The upper reinforcement section is set to be the same length as the reinforcement 6 above the adjustment mechanism, and the lower reinforcement section is set to be the same length as the reinforcement 6 below the adjustment mechanism. The vertical reinforcements 7 are respectively made of steel plates and are provided with connecting holes 71 that penetrate their thickness.

[0060] S2. Place the screw-free reinforcement device for the preliminarily fixed structural beam formwork on the outside of the bottom formwork and side formwork of the installed structural beam;

[0061] Specifically, during installation, try to make the two side supports symmetrically arranged on the side formwork of the structural beam, and the bottom support fit as close to the bottom support as possible;

[0062] S3. Adjust the length of the bottom support so that the side support clamps the side template; adjust the length of the side support so that the bottom support touches the bottom template;

[0063] Specifically, the rotating part 11 is inserted into the adjusting hole 21 on the adjusting part 2, and the rotating part 11 is screwed so that the connecting part 1 is continuously extended into the fixing part 3 or the reinforcing part 6, thereby driving the side support parts to approach each other to clamp the side formwork of the structural beam, and driving the bottom support part to move upward to support the bottom formwork of the structural beam.

[0064] S4. Install the tensioning member 8 to securely connect the upper and lower reinforcement sections on the side support members;

[0065] 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 holes 71 of the upper and lower reinforcing sections by fasteners passing through the connecting groove; the fasteners are bolts and nuts.

[0066] S5. Set up the beam bottom formwork support system so that the top support is stuck in the top support limiter 4 at the bottom of the bottom support member extension section 31, and the support rods at the bottom of the top support are symmetrically arranged below the structural beam formwork screw-free reinforcement device;

[0067] Specifically, when erecting the vertical support, the top support is clamped in the top support limiter 4 and a steel pipe is added to form an effective support for the bottom support member;

[0068] S6. Install the diagonal bracing reinforcement member and adjust the length of the diagonal bracing reinforcement member so that its two ends respectively abut against the vertical reinforcement member 7 and the extension section 31;

[0069] The length of the diagonal bracing reinforcement is preliminarily 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. The extension of the diagonal bracing reinforcement is then controlled by the adjustment mechanism so that the connectors respectively abut the two limiting grooves 5.

[0070] S7. Complete the installation of all screw-free reinforcement devices for the structural beam formwork in the length direction of the structural beam in sequence.

[0071] Specifically, the number, position and installation sequence of the screw-free reinforcement devices for the structural beam formwork are determined based on the force calculation of the structural beam.

[0072] The embodiments of the present invention are described in detail above, but the contents described are only preferred embodiments of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
