Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of reinforcement equipment for building construction, and in particular to a temporary reinforcement and adjustment diagonal support structure for formwork wall columns. Background Technology
[0002] During the construction process, temporary inclined support structures are needed during the casting stage of the formwork wall columns to ensure their verticality and stability.
[0003] Currently, the commonly used supports on construction sites are mostly exposed turnbuckle structures, which have obvious shortcomings in practical applications. When pouring concrete, splashed mortar easily adheres to the threaded connection of the turnbuckle. After the mortar solidifies, the threads will be jammed, making it impossible to rotate and disassemble normally. Most supports can only be used once, resulting in a high loss rate and directly increasing construction costs. In addition, when adjusting the length of this type of turnbuckle support, workers need to manually screw it in, which is quite laborious.
[0004] To address the aforementioned issues, this utility model document proposes a temporary reinforcement and adjustment diagonal support structure for molded wall columns. Utility Model Content
[0005] This utility model provides a temporary reinforcement and adjustment diagonal support structure for molded wall columns, which solves the shortcomings of the existing exposed turnbuckle diagonal supports, such as easy jamming by mortar, high wear and tear, and laborious manual tightening.
[0006] This utility model provides the following technical solution: A temporary reinforcement and adjustment diagonal bracing structure for formwork wall columns includes: A hollow tube has internal threads at both ends of its inner wall. A matching external threaded rod is threaded to the internal thread. The other end of the external threaded rod extends to the outside of the tube opening and is fixedly mounted with a centrally hollow connecting block. A corresponding hinge seat is hinged to the connecting block. Two threaded holes are symmetrically arranged on the side walls at both ends of the hollow tube. A dirt-proof cloth cover is glued to the outer wall of the connecting block.
[0007] In one possible design, mounting plates are fixedly installed on both sides of the outer wall of the hinge seat. The center of the mounting plate is provided with a reserved hole for fixing to the mounting surface by bolts. Two triangular reinforcing plates are symmetrically fixed at the angle between the mounting plate and the hinge seat.
[0008] In one possible design, an outer hexagonal tube is fixedly provided in the center of the outer wall of the hollow tube to facilitate the use of a wrench for tightening and to strengthen the hollow area of the hollow tube.
[0009] In one possible design, the two internal threads are arranged in opposite directions.
[0010] In one possible design, the threaded hole is threaded with a corresponding reinforcing bolt, and the ends of the two reinforcing bolts in each group are tightly abutted against the outer wall of the corresponding external thread rod.
[0011] In one possible design, the bottom end of the stain-resistant cloth cover is sewn with two binding ropes.
[0012] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.
[0013] The working principle and usage process of this technical solution are as follows: When using it, determine the installation points of the diagonal brace according to the reinforcement requirements of the formwork wall column. One end corresponds to the installation surface on the outside of the formwork wall column, and the other end corresponds to the installation surface of the pre-embedded ground anchor or trestle in the floor slab. Mark the bolt fixing position and ensure that the angle between the line connecting the two points and the ground meets the stability requirement of 45°~60°. Then, attach the hinge seats at both ends of the device to the preset installation surface. Using the reserved hole in the center of the installation plate, fasten the hinge seat to the installation surface with bolts. The hinge seat and the connecting block are connected by hinges, which can automatically adapt to the deflection according to the angle of the installation surface, avoiding the support force shift due to uneven installation points. At the same time, the triangular reinforcement plate at the angle between the installation plate and the hinge seat can enhance the load-bearing strength of the installation plate and prevent the installation plate from deforming during the fixing process. Then, a wrench is engaged with the hexagonal tube in the center of the hollow tube's outer wall, and the hollow tube is screwed on. Since the internal threads at both ends of the hollow tube are in opposite directions, the rotation will synchronously drive the external thread rods at both ends to extend and retract along the hollow tube's axis. When rotating in the forward direction, the external thread rods at both ends will extend or retract synchronously, and when rotating in the reverse direction, they will move in the opposite direction, realizing rapid adjustment of the support length. The hexagonal tube provides a force application point for the wrench, avoiding the laborious manual screwing, and can also strengthen the structural strength of the hollow area of the hollow tube, improving the support strength. When the diagonal support length is adjusted to the preset value and the verticality of the formwork wall column meets the requirements, the reinforcing bolts are screwed into the symmetrical threaded holes on the side walls at both ends of the hollow tube until the ends of the two reinforcing bolts in each group are tightly against the outer wall of the corresponding external thread rod. The friction further locks the relative position of the external thread rod and the hollow tube, which helps to ensure the stability of the support. Finally, unfold the anti-fouling cloth cover pre-fixed to the outer wall of the connecting block to cover the exposed threaded area of the connection between the hollow tube and the external threaded rod. Then, use the two binding ropes sewn at the bottom of the anti-fouling cloth cover to wrap and tighten it to achieve closed protection of the exposed threads, preventing mortar from entering the thread gap and causing difficulties in subsequent disassembly. After the concrete strength reaches the standard, first untie the binding ropes, remove the anti-fouling cloth cover, then unscrew the reinforcing bolts at both ends of the hollow tube, and use a wrench to turn the external hexagonal tube in the opposite direction to drive the external threaded rods at both ends to retract into the hollow tube simultaneously, shortening the support length. Finally, remove the fixing bolts between the hinge seat and the mounting surface to complete the dismantling of the entire device. It can be reused after cleaning.
[0014] This utility model has the following beneficial effects: This invention effectively prevents mortar splashed during concrete pouring from adhering to the threaded connection between the hollow pipe and the external threaded rod by setting an adhesive-fixed anti-fouling cloth cover on the outer wall of the connecting block and using a binding rope to seal the exposed threaded area. This avoids the problem of the threads getting stuck and unable to be disassembled after the mortar solidifies. Compared with the existing one-time-use exposed turnbuckle, this device is easy to clean after disassembly and can be reused multiple times, significantly reducing construction costs.
[0015] The outer hexagonal tube in the center of the hollow tube provides a stable point of force application for the wrench, avoiding the laborious problem of manual tightening, while strengthening the structural strength of the hollow tube; the reinforcing bolt achieves secondary locking by tightly pressing against the external threaded rod, further improving the support stability.

[0018] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0019] In the description of this utility model, it should be understood that the terms "opening", "upper", "middle", "length", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0020] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.
[0021] In one embodiment: Please refer to Figure 1-4 A diagonal bracing structure, comprising: The hollow tube 1, made of high-strength seamless steel pipe, ensures the load-bearing strength during the support process. The surface of the external thread rod 3 is treated with anti-rust to extend its service life. Before construction, the assembly of each component must be completed. The inner walls of the hollow tube 1 are pre-machined with internal threads 2 at both ends. The two internal threads 2 are set in opposite directions to provide a basis for the subsequent synchronous adjustment of the extension and retraction of the external thread rod 3 at both ends. The external thread rod 3 is screwed into the internal threads 2 at both ends of the hollow tube 1 to ensure that the threaded connection is tight and without looseness. One end of the external thread rod 3 remains inside the hollow tube 1, and the other end passes through to the outside of the tube opening and is fixedly connected to the central hollow connecting block 4 by welding. The welded joint needs to be ground to avoid sharp protrusions that may affect subsequent use. The connecting block 4 is hinged to the hinge seat 5 by a pin to ensure that the hinge seat 5 can be flexibly deflected relative to the connecting block 4 to meet the adaptation requirements of various installation angles.
[0022] Mounting plates 6 are welded to both sides of the outer wall of the hinge base 5. A pre-drilled hole 7 is reserved in the center of the mounting plate 6. The diameter of the pre-drilled hole 7 matches the specifications of the fixing bolts used in the construction. To enhance the load-bearing capacity of the mounting plate 6, two triangular reinforcing plates 8 are symmetrically welded at the angle between the mounting plate 6 and the hinge base 5. The triangular reinforcing plates 8 are firmly connected to the mounting plate 6 and the hinge base 5 by full welding to prevent the mounting plate 6 from deforming due to stress during the fixing process.
[0023] A hexagonal tube 9 is welded and fixed to the center of the outer wall of the hollow tube 1. The specifications of the hexagonal tube 9 are compatible with common wrenches, which can provide a stable force application point for subsequent tightening of the hollow tube 1, and also strengthen the hollow area of the hollow tube 1, thereby improving the overall structural support strength. Two threaded holes 10 are symmetrically machined on the side walls at both ends of the hollow tube 1. The position of the threaded holes 10 corresponds to the position of the external threaded rod 3 after it is screwed in, ensuring that the reinforcing bolts 11 can accurately abut against the external threaded rod 3 after being screwed in. A dirt-proof cloth cover 12 is glued and fixed to the outer wall of the connecting block 4 with a special adhesive. The dirt-proof cloth cover 12 is made of waterproof and wear-resistant non-woven fabric, and its size must cover the exposed threaded area of the connection between the hollow tube 1 and the external threaded rod 3. Two binding ropes 13 are sewn and fixed to the bottom of the dirt-proof cloth cover 12 with needle and thread. The binding ropes 13 must have sufficient tensile strength.
[0024] In practical use, first determine the installation points of the diagonal brace according to the reinforcement requirements of the formwork wall column. One end corresponds to the installation surface on the outside of the formwork wall column, and the other end corresponds to the installation surface of the pre-embedded ground anchor or trestle in the floor slab. Mark the bolt fixing positions corresponding to the reserved holes 7 on the mounting plate 6 with a marker, ensuring that the angle between the line connecting the two installation points and the ground is within a stable range of 45° to 60°. This angle range can maximize the load-bearing stability of the support structure. Then, attach the hinge seats 5 at both ends of the device to the preset installation surfaces and adjust the hinge seats. The angle of the mounting plate 6 is adjusted to ensure it is fully flush with the mounting surface. The bolts are then passed through the pre-drilled hole 7 in the center of the mounting plate 6 and tightened to the mounting surface, completing the initial fixing of both ends of the device. Since the hinge seat 5 and the connecting block 4 are hinged, they can automatically adapt to the deflection according to the actual angle of the mounting surface, effectively avoiding the problem of support force shift due to uneven mounting points. At the same time, the triangular reinforcing plate 8 at the angle between the mounting plate 6 and the hinge seat 5 can further enhance the load-bearing strength of the mounting plate 6 and prevent the mounting plate 6 from deforming during the fixing process. After initial fixing at both ends, the support length is adjusted. The worker holds a wrench and engages it with the external hexagonal tube 9 at the center of the outer wall of the hollow tube 1. By turning the wrench on the hollow tube 1, the internal threads 2 at both ends of the hollow tube 1 move in opposite directions. Rotating the hollow tube 1 synchronously drives the external threaded rods 3 at both ends to extend or retract along the axial direction of the hollow tube 1. When rotating the hollow tube 1 in the forward direction, the external threaded rods 3 at both ends extend or retract synchronously; when rotating in the reverse direction, they move in the opposite direction. This method allows for rapid adjustment of the support length. The external hexagonal tube 9 provides a stable point of force application for the wrench, avoiding the laborious problem of manually turning the hollow tube 1. It also strengthens the structural strength of the hollow area of the hollow tube 1, further improving the overall support strength. Once the diagonal support length is adjusted to the preset value, and the verticality of the formwork wall column is confirmed by a level to meet the construction requirements, turning the hollow tube 1 is stopped, and the process continues... To lock the support length, screw the reinforcing bolts 11 into the symmetrical threaded holes 10 on the side walls at both ends of the hollow tube 1. Tighten the reinforcing bolts 11 until the ends of the two reinforcing bolts 11 in each group are tightly against the outer wall of the corresponding external thread rod 3. The friction between the reinforcing bolts 11 and the external thread rod 3 further locks the relative position of the external thread rod 3 and the hollow tube 1, which helps to ensure the stability of the support. After the locking operation is completed, the exposed threads are protected. The anti-fouling cloth cover 12, which is pre-glued and fixed on the outer wall of the connecting block 4, is unfolded outward so that the anti-fouling cloth cover 12 completely covers the exposed thread area of the connection between the hollow tube 1 and the external thread rod 3. Then, the two binding ropes 13, which are sewn and fixed at the bottom of the anti-fouling cloth cover 12, are wrapped and tied together. The binding effect of the binding ropes 13 keeps the anti-fouling cloth cover 12 in a covered state, realizing the closed protection of the exposed threads and preventing the mortar splashed during the concrete pouring process from entering the thread gap and causing subsequent disassembly difficulties.
[0025] This application can be used for temporary reinforcement of formwork wall columns, and can also be used in other fields applicable to this application.
[0026] In another embodiment: A temporary reinforcement and adjustment diagonal support structure for formwork wall columns is used in the field of reinforcement equipment for building construction. The structure of this embodiment is basically the same as that of the aforementioned embodiments, except that: Please refer to Figure 1-4When dismantling the device, first untie the binding rope 13 at the bottom of the anti-fouling cloth cover 12, and clean the small amount of mortar adhering to the surface of the anti-fouling cloth cover 12 for later reuse. Then, use a wrench to unscrew the reinforcing bolts 11 at both ends of the hollow tube 1, release the locking state between the external thread rod 3 and the hollow tube 1, and then re-lock the wrench on the external hexagonal tube 9, and turn the hollow tube 1 in the opposite direction to drive the external thread rod 3 at both ends to retract into the hollow tube 1 simultaneously, shortening the overall support length and creating a gap between the device and the formwork wall column and floor slab installation surface. Finally, unscrew the fixing bolts on the mounting plate 6 of the hinge seat 5 to complete the dismantling of the entire device. After dismantling, the device needs to be cleaned uniformly to remove the mortar and other debris adhering to the surface, check the threaded connection status of each component and the flexibility of the hinge parts, and after confirming that there is no damage, it can be stored for reuse.
