Description

Technical Field

[0001] This invention relates to the field of building engineering technology, and in particular to a high formwork system and its construction process. Background Technology

[0002] High formwork is a formwork support system used in building construction to support concrete beams, slabs, columns and other components. The erection height, span or load of high formwork usually exceeds the conventional standards. The erection of high formwork is a key link in ensuring the quality of concrete pouring and construction safety in high-rise buildings, large public buildings and other projects.

[0003] The basic structure of existing high-support formwork mainly consists of support components such as uprights, horizontal bars, and diagonal braces. These components are connected at nodes to form a spatial support frame system. The uprights serve as the main load-bearing components to bear vertical loads, while the horizontal bars connect the uprights laterally to form a basic support grid. The diagonal braces enhance the stability of the overall structure through their connection with the uprights and horizontal bars, thus forming a rigid support system capable of bearing the self-weight of the poured concrete and construction loads.

[0004] In existing technologies, the connection between uprights relies on traditional methods such as bolt tightening and pin insertion. These connection structures lack standardized quick-installation interface designs, requiring manual alignment and calibration of each node's positioning accuracy. Furthermore, each connection node undergoes repetitive tightening and insertion operations multiple times. The lack of a modular quick-installation system in the connection structure leads to several shortcomings in the upright assembly process: Firstly, the installation of a single node requires multiple steps, including alignment, fixing, and tightening. Connecting hundreds or thousands of nodes in a high-rise, high-formwork system significantly reduces overall assembly efficiency compared to systems using quick-installation interfaces, potentially causing delays, especially in projects with tight schedules. Secondly, manual operation is affected by factors such as skill level and worker fatigue, often resulting in inconsistent tightness of connection nodes and vertical deviations exceeding permissible limits. This leads to uneven overall stiffness of the support system, significantly increasing the risk of localized deformation due to loose nodes during concrete pouring, and even affecting structural quality and construction safety. Summary of the Invention

[0005] The purpose of this invention is to provide a high-support formwork and its construction process, which solves the problems in the prior art where the lack of standardized quick-installation interfaces for pole connections leads to low assembly efficiency, insufficient precision of manual operation causing uneven stiffness of the support system and construction deformation risks.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A high-support formwork includes a base, on the top of which are mounted multiple sweeping rods. A first upright is slidably connected to one end of each sweeping rod away from the base. A second upright is mounted to the end of the first upright away from the sweeping rods. A top support is mounted to the end of the second upright away from the first upright. A horizontal bar is installed between the sweeping rods. Horizontal mounting components are provided at both ends of the horizontal bar. A height adjustment component is provided between the sweeping rods and the first upright. A circular tube is fixedly connected to the end of the second upright near the first upright. A locking block is symmetrically arranged on the outer side of the circular tube. A spring is fixedly connected to the end of each locking block near the circular tube. A threaded rod is fixedly connected to the bottom of the circular tube and threadedly connected to the inside of the first upright. A reinforcing auxiliary component is provided between the sweeping rod and the first upright. A disassembly / removal component is provided between the second upright and the top support. Preferably, the height adjustment assembly includes a bolt, which is installed between the sweeping rod and the upright rod. The upright rod has evenly spaced bolt holes on one side near the bolt. The sweeping rod has a movable groove inside, including a mounting seat. The mounting seat is fixedly connected to the sweeping rod on the side near the horizontal rod. A bolt is installed between the horizontal rod and the mounting seat. The mounting seat has a movable groove in the middle, and the horizontal rod has bolt holes in the middle.

[0007] Preferably, the reinforced auxiliary component includes a universal joint, which is fixedly connected to the upright pole, a connecting block is fixedly connected to the sweeping pole, a rotating shaft is rotatably connected inside the connecting block, and a reinforcing tube is fixedly connected between the universal joint and the rotating shaft.

[0008] Preferably, the disassembly and assembly assembly includes a connecting block, which is fixedly connected to the top support on the side near the second upright. A bolt is installed between the connecting block and the second upright. A movable groove is provided inside the second upright. A bolt hole is provided on the side of the connecting block near the bolt. The bolt is threaded to the middle of the bolt hole. The connecting block is slidably connected to the middle of the movable groove.

[0009] Preferably, the first upright has a slot inside, and the locking block engages with the slot.

[0010] Preferably, the inside of the circular tube has a through hole, and the spring abuts between the circular tube and the locking block.

[0011] Preferably, the bolt is threaded to the middle of the bolt hole, and the upright is slidably connected to the middle of the movable groove.

[0012] Preferably, the horizontal bar is slidably connected to the middle of the movable groove two, and the bolt two is threadedly connected to the middle of the bolt hole two.

[0013] A high-formwork construction process includes the following steps: S1. Measure and mark the installation position of the pad on the construction reference surface, and fix the pad to the ground with expansion bolts.

[0014] S2. Construct a sweeping rod support system. Install multiple sweeping rods on the top of the pad using bolt connections. The spacing between adjacent sweeping rods is arranged according to the design drawings and fixed with right-angle fasteners.

[0015] S3. Adjust the installation height of the upright pole. Insert the lower end of the upright pole into the movable slot of the sweeping pole. Screw the bolt through the movable slot into the bolt hole of the upright pole. Adjust the position of the bolt corresponding to the bolt hole according to the construction height requirements.

[0016] S4. Connect the second upright to the first upright. Screw the threaded rod at the bottom of the second upright into the threaded hole at the top of the first upright. Rotate the second upright clockwise until it can no longer be rotated, thus completing the vertical connection of the uprights.

[0017] S5. Install the horizontal bar to form a support grid. Align both ends of the horizontal bar with the mounting base on the outside of the sweeping bar. Use bolt 2 to screw into bolt hole 2 of the horizontal bar through the movable groove 2 of the mounting base and tighten it.

[0018] S6. Install the reinforcement auxiliary components. Fix one end of the reinforcement tube to the upright first through a universal joint, and rotate the other end to the connecting block of the sweeping rod through a rotating shaft. After adjusting to the design angle, lock the universal joint.

[0019] S7. Fix the top support to the top of the second upright, insert the connecting block at the bottom of the top support into the movable groove three of the second upright, and screw the bolt three through the movable groove three into the bolt hole three of the connecting block and tighten it.

[0020] S8. Overall structural pre-stress test: Apply 120% of the design load to the top support, check the stability of the overall connection nodes and support system of the uprights, and unload after confirming that there are no abnormalities.

[0021] In summary, the present invention has at least one of the following beneficial technical effects: 1. This invention aligns and screws the threaded rod at the bottom of the second upright with the threaded hole on the inner wall of the first upright. During the rotation of the second upright, the locking block on the outside of the round tube pops out under the thrust of the spring and embeds into the locking groove on the inner wall of the first upright. Through the threaded connection of the threaded rod and the locking engagement of the locking block and the locking groove, the vertical connection between the first upright and the second upright is quickly locked, avoiding the low efficiency and insufficient accuracy of manual alignment calibration in traditional connection methods.

[0022] 2. This invention installs multiple sweeping rods on the top of the pad, sets a movable groove between the sweeping rods and the upright, inserts the lower end of the upright into the movable groove, and uses a bolt to pass through the movable groove and screw into the bolt hole on the upright. By adjusting the position of the bolt in different bolt holes, the height of the upright can be flexibly adjusted, solving the problem of cumbersome upright height adjustment in traditional processes.

[0023] 3. This invention achieves fixed installation of the horizontal bar and the sweeping bar by opening bolt holes at both ends, fixing a mounting base on the outside of the sweeping bar and opening a movable groove, aligning the horizontal bar with the movable groove of the mounting base, passing a bolt through the movable groove and screwing it into the bolt hole, and using the movable groove to limit the bolt and the threaded connection between the bolt and the bolt hole to achieve fixed installation of the horizontal bar and the sweeping bar, forming a modular installation of the horizontal support grid, thus improving the installation efficiency of the horizontal support system.

[0024] 4. This invention provides multi-angle support to counteract lateral deformation when the upright is under stress by strengthening the connection between the universal joints and the pivot at both ends of the tube and the upright and the sweeping rod. At the same time, the assembly and disassembly components consisting of the bottom connecting block of the top support, the movable groove of the upright, and the bolts enable the quick fixing and disassembly of the top support, ensuring the stability and ease of disassembly of the overall structure of the high formwork.

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1: Please see the appendix Figure 1 - Appendix Figure 3 This invention provides a high formwork support, including a base 1. Multiple sweeping rods 2 are mounted on the top of the base 1. A first upright 3 is slidably connected to the end of each sweeping rod 2 away from the base 1. A second upright 4 is mounted to the end of the first upright 3 away from the sweeping rods 2. A top support 10 is mounted to the end of the second upright 4 away from the first upright 3. A horizontal bar 5 is installed between the sweeping rods 2. Horizontal mounting components 7 are provided at both ends of the horizontal bar 5. A height adjustment component 6 is provided between the sweeping rods 2 and the first upright 3. The end of the second upright 4 near the first upright 3 is fixedly connected to... There is a round tube 11, and symmetrically arranged locking blocks 12 on the outer side of the round tube 11. A spring 14 is fixedly connected to one end of the locking block 12 near the round tube 11. A threaded rod 15 is fixedly connected to the bottom of the round tube 11. The threaded rod 15 is threadedly connected to the inside of the upright 3. A reinforcing auxiliary component 8 is arranged between the sweeping rod 2 and the upright 3. A disassembly and assembly component 9 is arranged between the upright 4 and the top support 10. A locking groove 13 is opened inside the upright 3 for locking. A through hole 16 is opened inside the round tube 11. The spring 14 abuts between the round tube 11 and the locking block 12.

[0029] Specifically, by connecting the threaded rod 15 at the bottom of the second upright 4 to the inside of the first upright 3, during the process of rotating the second upright 4 to screw the threaded rod 15 into the first upright 3, the locking block 12 on the outside of the round tube 11 first compresses the spring 14. After the threaded rod 15 rotates to the designated position, the locking block 12 is pushed outward by the spring 14 and embedded in the locking groove 13 on the inner wall of the first upright 3. The threaded connection of the threaded rod 15 bears the vertical load, while the locking structure of the locking block 12 and the locking groove 13 prevents relative rotation between the uprights. The two work together to complete the connection and locking of the first upright 3 and the second upright 4, which helps to improve the reliability of the upright connection, avoids the problem of loosening of nodes caused by manual operation in traditional connection methods, and effectively ensures the overall stability of the support system.

[0030] Please see the appendix Figure 4 - Appendix Figure 5 This invention provides a high formwork support. The height adjustment component 6 includes a bolt 61, which is installed between a sweeping rod 2 and a vertical rod 3. The vertical rod 3 has bolt holes 62 evenly distributed on the side near the bolt 61. The sweeping rod 2 has a movable groove 63 inside. The bolt 61 is threaded to the middle of the bolt hole 62, and the vertical rod 3 is slidably connected to the middle of the movable groove 63.

[0031] Specifically, by inserting the lower end of the upright pole 3 into the movable slot 63 inside the sweeping pole 2, the bolt 61 passes through the movable slot 63 and is screwed into the bolt hole 62 on the upright pole 3. By adjusting the position of the bolt 61 in different bolt holes 62, the height of the upright pole 3 can be adjusted, which helps to meet the needs of different construction floor heights, avoids the problem of low construction efficiency caused by inconvenient height adjustment in traditional processes, and effectively improves the flexibility and adaptability of high formwork installation.

[0032] Please see the appendix Figure 1 and attached Figure 6 This invention provides a high formwork support. The horizontal installation component 7 includes a mounting base 71, which is fixedly connected to the side of the sweeping rod 2 near the horizontal rod 5. A bolt 72 is installed between the horizontal rod 5 and the mounting base 71. The mounting base 71 has a movable groove 74 in the middle, and the horizontal rod 5 has a bolt hole 73 in the middle. The horizontal rod 5 is slidably connected to the middle of the movable groove 74, and the bolt 72 is threadedly connected to the middle of the bolt hole 73.

[0033] Specifically, by fixing the mounting base 71 on the outside of the sweeping rod 2 and opening the movable groove 74, aligning the two ends of the horizontal rod 5 with the movable groove 74, and screwing the bolt 72 through the movable groove 74 into the bolt hole 73, the horizontal rod 5 and the sweeping rod 2 are fixed together to form a horizontal support structure. This method is simple to install and effectively improves the assembly efficiency and structural integrity of the horizontal support system.

[0034] Please see the appendix Figure 1 and attached Figure 7 This invention provides a high formwork support, and the reinforced auxiliary component 8 includes a universal joint 81, which is fixedly connected to the upright 3. A connecting block 83 is fixedly connected to the sweeping rod 2, and a rotating shaft 84 is rotatably connected inside the connecting block 83. A reinforcing tube 82 is fixedly connected between the universal joint 81 and the rotating shaft 84.

[0035] Specifically, by fixing one end of the reinforcing tube 82 to the upright 3 via a universal joint 81, and rotatably connecting the other end to the connecting block 83 on the sweeping rod 2 via a rotating shaft 84, when the upright is under stress, the universal joint 81 and the rotating shaft 84 rotate together, causing the reinforcing tube 82 to generate axial support force to counteract the lateral deformation of the upright. This method utilizes the multi-directional rotation characteristics of the universal joint 81 and the flexible rotation capability of the rotating shaft 84, which helps to provide stable support for the upright under different force directions, avoids the support blind spot caused by the fixed angle of the traditional diagonal bracing structure, and effectively improves the lateral stiffness and stability of the overall high formwork structure.

[0036] Please see the appendix Figure 1 and attached Figure 8 This invention provides a high formwork support. The disassembly and assembly component 9 includes a connecting block 91, which is fixedly connected to the top support 10 on the side near the second upright 4. A bolt 92 is installed between the connecting block 91 and the second upright 4. The second upright 4 has a movable groove 94 inside. The connecting block 91 has a bolt hole 93 on the side near the bolt 92. The bolt 92 is threadedly connected to the middle of the bolt hole 93. The connecting block 91 is slidably connected to the middle of the movable groove 94.

[0037] Specifically, by inserting the connecting block 91 at the bottom of the top support 10 into the movable groove 94 inside the upright 2 4, the bolt 3 92 passes through the movable groove 3 94 and is screwed into the bolt hole 3 93 on the connecting block 91, the top support 10 is fixed to the top of the upright 2 4 to support the formwork and concrete load. It is easy to disassemble and helps to improve the installation and disassembly efficiency of the top support 10.

[0038] Example 2: Please see the appendix Figure 1 - Appendix Figure 8 This invention provides a high-formwork construction process, including the following steps: S1. Measure and lay out the positioning pad 1. Mark the installation position of pad 1 on the construction reference surface and fix pad 1 to the ground with expansion bolts.

[0039] S2. Construct a support system for the sweeping rods 2. Install multiple sweeping rods 2 on the top of the pad 1 using bolt connections. The spacing between adjacent sweeping rods 2 is arranged according to the design drawings and fixed with right-angle fasteners.

[0040] S3. Adjust the installation height of the upright pole 3. Insert the lower end of the upright pole 3 into the movable slot 63 of the sweeping pole 2. Screw the bolt 61 through the movable slot 63 into the bolt hole 62 of the upright pole 3. Adjust the position of the bolt 61 corresponding to the bolt hole 62 according to the construction height requirements.

[0041] S4. Connect the second upright 4 with the first upright 3. Screw the threaded rod 15 at the bottom of the second upright 4 into the threaded hole at the top of the first upright 3. Rotate the second upright 4 clockwise until it can no longer be rotated, thus completing the vertical connection of the uprights.

[0042] S5. Install the horizontal bar 5 to form a support grid. Align the two ends of the horizontal bar 5 with the mounting base 71 on the outside of the sweeping bar 2. Use bolt 2 72 to pass through the movable groove 2 74 of the mounting base 71 and screw it into the bolt hole 2 73 of the horizontal bar 5 and tighten it.

[0043] S6. Install the reinforcement auxiliary component 8. Fix one end of the reinforcement tube 82 to the upright 3 through the universal joint 81, and rotate the other end to the connecting block 83 of the sweeping rod 2 through the rotating shaft 84. After adjusting to the design angle, lock the universal joint 81.

[0044] S7. Fix the top support 10 to the top of the second pole 4, insert the connecting block 91 at the bottom of the top support 10 into the movable groove 3 94 of the second pole 4, and screw the bolt 3 92 through the movable groove 3 94 into the bolt hole 3 93 of the connecting block 91 and tighten it.

[0045] S8. Overall structural pre-stress test: Apply 120% of the design load to the top support 10, check the stability of the overall connection nodes and support system of the uprights, and unload after confirming that there are no abnormalities.

[0046] Specifically, when installing high formwork, first place the pad 1 in the designated position, install multiple sweeping rods 2 on the top of the pad 1, then insert the lower end of the upright 3 into the movable groove 63 inside the sweeping rod 2, and use bolts 61 to pass through the movable groove 63 and screw into the bolt hole 62 on the upright 3 to achieve initial fixation between the upright 3 and the sweeping rod 2. At this time, the height of the upright 3 can be adjusted by adjusting the position of the bolts 61 in different bolt holes 62. Then, the threaded rod 15 at the bottom of the second upright 4 is threaded to the first upright 3. During the process of rotating the second upright 4 to screw the threaded rod 15 into the first upright 3, the locking block 12 on the outside of the round tube 11 pops out under the pushing force of the spring 14 and is embedded in the locking groove 13 on the inner wall of the first upright 3, thus completing the connection and locking between the first upright 3 and the second upright 4. When installing the horizontal bar 5 between the sweeping bars 2, the two ends of the horizontal bar 5 are aligned with the movable groove 74 on the mounting base 71 fixed on the outside of the sweeping bar 2. The bolt 72 is screwed into the bolt hole 73 through the movable groove 74 to fix the horizontal bar 5 to the sweeping bar 2, forming a horizontal support structure. To enhance the stability of the overall structure, a reinforcing auxiliary component 8 is installed between the upright 3 and the sweeping rod 2. One end of the reinforcing tube 82 is fixed to the upright 3 via a universal joint 81, and the other end is rotatably connected to the connecting block 83 on the sweeping rod 2 via a pivot 84, so as to provide support when the upright is under stress and to counteract lateral deformation. Finally, install the top support 10 at the top of the second upright 4, insert the connecting block 91 at the bottom of the top support 10 into the movable groove 94 inside the second upright 4, and screw the bolt 92 through the movable groove 94 into the bolt hole 93 on the connecting block 91 to fix the top support 10, which is used to support the formwork and concrete load, and realize the modular installation of the top support 10. When the high formwork bears a load, the weight of the concrete is transferred to the second upright 4 through the top support 10, and then to the first upright 3 through the round pipe 11 and the threaded rod 15. Then, it is distributed to the pad 1 through the support system composed of the sweeping rod 2 and the horizontal rod 5. In this process, the cooperation of the locking block 12 and the locking groove 13 and the action of the spring 14 ensure the firmness of the upright connection node and avoid loosening. The synergistic effect of the reinforcing pipe 82, the universal joint 81 and the rotating shaft 84 effectively suppresses the lateral displacement of the first upright 3 and the second upright 4, so that the entire high formwork forms a stable rigid support system.
