Description

Technical Field

[0001] This utility model relates to the field of steel frame formwork installation, specifically a quick-release support system for steel frame formwork used in construction. Background Technology

[0002] Construction steel frame formwork is a combined formwork system consisting of steel profiles forming the frame and embedded film-coated plywood or other panels. It features high strength and rigidity, ensuring accurate concrete molding dimensions and a smooth, flat surface that meets fair-faced concrete standards. It has a high turnover rate; the steel frame can typically be used for more than 5 years, and the panels can be reused 30-50 times. It has low amortization costs and significant economic benefits.

[0003] Currently, steel frame formwork is widely used in the construction industry due to its advantages such as high turnover and low cost. However, there is a problem in its actual construction process. Specifically, the traditional structure for splicing adjacent steel frame formwork is mostly a tenon and mortise structure or a tie bolt structure, which has poor construction convenience and wastes a lot of material costs during turnover. In view of this, the inventor urgently needs to design a quick-release support mechanism for steel frame formwork to improve the efficiency and cost of steel frame formwork in the turnover process. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a quick-release support system for steel frame formwork in construction, so as to solve the technical problems of low turnover efficiency and waste of a lot of material costs of traditional steel frame formwork.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-release support system for steel frame formwork in construction, including a top support and a base plate, wherein a connecting pipe is inserted and welded to the bottom of the top support, and a central axis tube is inserted and sleeved on the outside of the connecting pipe; A base connecting pipe is sleeved and welded to the top of the base plate. A locking buckle is welded to the outside of the base connecting pipe. A support platform and a disassembly buckle are engaged on the outside of the locking buckle. Support columns are fixedly installed at the four corners above the support platform. The angle of the steel frame template is engaged with the support columns.

[0006] By adopting the above technical solutions, each component can be manufactured, transported and replaced independently, which greatly facilitates warehousing, transportation and on-site management. During on-site construction, workers do not need to perform complex on-site welding or cutting, but only need to assemble according to the clear connection relationship, which significantly reduces the dependence on highly skilled workers and greatly shortens the construction time.

[0007] Furthermore, the connecting pipe and the central shaft pipe are connected by a pin assembly, and the central shaft pipe is welded to the locking buckle.

[0008] By adopting the above technical solution, the pin connection is an extremely fast, tool-free connection method, which provides basic adjustability for the height of the support pole. At the same time, it also allows the top support unit to be easily separated from the middle support unit, which facilitates flexible configuration or partial replacement and maintenance, greatly enhancing the adaptability of the entire system.

[0009] Furthermore, the disassembly buckle includes a support frame, the inner side of which has a retaining edge, and a retaining groove is provided on the retaining edge.

[0010] The locking buckle includes a locking tube body, and two sets of first locking blocks and second locking blocks are fixedly arranged on the outer side of the locking tube body, with a limiting groove formed between the first locking blocks and the second locking blocks.

[0011] By adopting the above technical solution, the engagement action of the disassembly buckle edge and the locking buckle limit groove is essentially a simple linear sliding or rotating snap-in action, which can be completed by hand by workers without the need to carry and operate tools such as wrenches. This saves time and avoids the problem of lost or damaged tools. This mechanism is the key to the quick disassembly of the entire system.

[0012] Furthermore, the first and second locking blocks are coaxially arranged, and the inner side of the support frame engages with the limiting groove through the locking edge. The locking groove is the avoidance point for the first locking block when the support frame and the locking buckle are installed.

[0013] The support platform includes a support plate, on which through holes and clearance grooves are formed. The through holes and clearance grooves are clearance points for the card tube body and the first card block when the support platform is engaged with the locking buckle.

[0014] By adopting the above technical solution, the disassembly clips and support platform can be easily guided to the only correct installation position after the central tube is put on, which greatly reduces the installation difficulty and avoids forced knocking or component damage caused by misalignment. Even unskilled workers can quickly master the process.

[0015] Furthermore, a retaining frame is fixedly provided on the support plate at a position opposite to the clearance groove. The retaining frame engages with the first retaining block to limit the axial angle of the support platform.

[0016] By adopting the above technical solution, the construction equipment will generate continuous vibration during the concrete pouring and vibration process. These vibrations can easily cause the platform components that are not axially limited to produce slight rotational displacement. Long-term accumulation may cause the buckle to loosen or the support to become inaccurate. The engagement of the clip frame and the first clip block forms an efficient anti-rotation mechanism, which firmly locks the bearing platform in the preset angle direction, completely eliminating this hidden danger.

[0017] In summary, the present invention has the following main advantages: 1. This utility model realizes prefabrication and rapid on-site assembly. The pin connection between the connecting pipe and the central shaft pipe, as well as the locking and unlocking actions of the buckles, are all tool-free operations, avoiding the tightening process and thread corrosion risk required by traditional bolt connections. This significantly shortens the installation and disassembly time, reduces reliance on skilled workers, and provides a foundation for the high-frequency turnover of the template. 2. In this utility model, the supporting column provides clear four-corner positioning for the steel frame formwork, limiting its horizontal displacement. More importantly, the clip frame on the supporting platform engages with the first clip block on the locking buckle, preventing the supporting platform from rotating circumferentially when under force, thus enhancing the overall torsional rigidity. The clip edge of the disassembly buckle and the limiting groove of the locking buckle form a vertical locking, which, together with the above-mentioned anti-rotation structure, constitutes a stable support platform that can reliably transmit the concrete pouring load, ensuring that the formwork does not settle or shift during construction, thereby ensuring the accuracy of the concrete structure dimensions and the flatness of the surface.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] In this embodiment: A quick-release support system for steel frame formwork in construction, such as Figure 1-8 As shown, it includes a top support 1 and a base plate 9. A connecting pipe 2 is inserted into and welded to the bottom of the top support 1, and a central shaft pipe 3 is inserted into and sleeved on the outside of the connecting pipe 2. A base connecting pipe 8 is sleeved and welded to the top of the base plate 9. A locking buckle 7 is welded to the outside of the base connecting pipe 8. A support platform 5 and a disassembly buckle 6 are engaged on the outside of the locking buckle 7. Support columns 4 are fixedly installed at the four corners of the support platform 5. The angle of the steel frame template engages with the support columns 4, allowing each component to be manufactured, transported, and replaced independently. This greatly facilitates warehousing, transportation, and on-site management. During on-site construction, workers do not need to perform complex on-site welding or cutting. They only need to assemble according to the clear connection relationship, which significantly reduces the reliance on highly skilled workers and greatly shortens the construction time. At the same time, the positioning method of directly engaging the support columns 4 with the corners of the steel frame template is adopted. The support columns 4 at the four corners form a stable support plane, which can effectively limit the displacement of the template in any horizontal direction and ensure that the template will not shift or warp during the concrete pouring process, thereby ensuring the accuracy of the forming dimensions and the surface flatness of the concrete structure.

[0022] See Figure 1 , Figure 2 The connecting pipe 2 and the central shaft pipe 3 are connected by a pin assembly. The central shaft pipe 3 is sleeved and welded to the locking buckle 7. The pin connection is an extremely quick and tool-free connection method, which provides basic adjustability for the height of the support pole. It also allows the top support unit 1 at the top to be easily separated from the middle support unit, which is convenient for flexible configuration or partial replacement and maintenance, greatly enhancing the adaptability of the entire system. At the same time, welding the central shaft pipe 3 and the lower locking buckle 7 into a whole component ensures the rigidity and integrity of the core load-bearing path from the base plate 9 to the locking buckle 7 and then to the central shaft pipe 3, forming a solid support. This not only can withstand the huge vertical pressure from above, but also effectively resist the lateral forces and vibrations that may be generated during concrete pouring, preventing the support system from becoming unstable.

[0023] See Figure 4 , Figure 5 The disassembly buckle 6 includes a support frame 601, and a retaining edge 603 is formed on the inner side of the support frame 601. A retaining groove 602 is provided on the retaining edge 603.

[0024] The locking buckle 7 includes a tube body 701. Two sets of first locking blocks 702 and second locking blocks 703 are fixedly arranged on the outer side of the tube body 701, and a limiting groove 704 is formed between the first locking blocks 702 and the second locking blocks 703.

[0025] The engagement of the disassembly clip 603 with the locking groove 704 of the locking clip 7 is essentially a simple linear sliding or rotating snap-fit ​​action, which can be completed by hand without the need to carry or operate tools such as wrenches. This saves time and avoids the problem of lost or damaged tools. This mechanism is the key to the quick disassembly of the entire system. At the same time, the snap-fit ​​connection has self-locking properties and extremely high fatigue resistance. Once the clip 603 is fully embedded in the locking groove 704, a reliable mechanical interlock is formed, effectively preventing accidental disengagement. Compared with traditional bolt connections, it completely eliminates the stubborn problem of being unable to tighten or disassemble due to thread corrosion, stripping, or wear, greatly increasing the number of turnovers and service life, and significantly reducing maintenance costs and wear on parts.

[0026] See Figure 4 , Figure 5 , Figure 6 The first locking block 702 and the second locking block 703 are coaxially arranged. The inner side of the support frame 601 is engaged with the limiting groove 704 through the locking edge 603. The locking groove 602 is the avoidance point of the first locking block 702 when the support frame 601 and the locking buckle 7 are installed.

[0027] The support platform 5 includes a support plate 501, on which a through hole 502 and a clearance groove 503 are formed. The through hole 502 and the clearance groove 503 are clearance points for the card tube body 701 and the first card block 702 when the support platform 5 is engaged with the locking buckle 7.

[0028] This design allows the disassembled clip 6 and support platform 5 to be easily guided to the correct installation position after the central tube 3 is fitted on, greatly reducing the installation difficulty and avoiding forced hammering or component damage caused by misalignment. Even unskilled workers can quickly master the process. At the same time, this precise avoidance setting is a prerequisite for subsequent effective engagement. It ensures that the clip frame 504 on the support platform 5 can descend without interference to the position precisely corresponding to the first clip block 702. This not only speeds up the installation process but, more importantly, ensures that all components can fit together tightly, eliminating the risk of local stress concentration or structural loosening caused by installation deviations. This ensures the stability and safety of the entire support platform under load.

[0029] See Figure 1 , Figure 4 , Figure 6A locking frame 504 is fixedly installed on the support plate 501 at a position opposite to the clearance groove 503. The locking frame 504 engages with the first locking block 702 to limit the axial angle of the bearing platform 5. During concrete pouring and vibration, the construction equipment will generate continuous vibration. These vibrations can easily cause slight rotational displacement of the platform components that are not axially limited. Long-term accumulation may cause the buckle to loosen or the support positioning to become inaccurate. The engagement of the locking frame 504 and the first locking block 702 forms an efficient anti-rotation mechanism, which firmly locks the bearing platform 5 in the preset angle direction, completely eliminating this hidden danger. At the same time, it enhances the lateral displacement resistance and overall rigidity of the entire support system. As a component that directly supports the steel frame formwork, the stability of the bearing platform 5 is directly related to the forming quality of the concrete structure. The cooperation between the locking frame 504 and the first locking block 702 tightly connects the bearing platform 5, the locking buckle 7, and the base below it into a whole, which significantly improves the ability of the support system to resist horizontal forces from all directions of the formwork.

[0030] The implementation principle of this embodiment is as follows: First, the central shaft tube 3, locking buckle 7, base connecting tube 8, and base plate 9 are sequentially welded and fixed using a welding process. Then, the support frame 601 is fitted onto the outside of the central shaft tube 3. Next, the central shaft tube 3 is moved downwards until the locking edge 603 is aligned with the limiting groove 704. Then, the support frame 601 is slid, causing the locking edge 603 to engage within the limiting groove 704, thus completing the installation of the locking buckle 7 and the disassembly buckle 6. Finally, the support plate 501 is fitted onto... On the outside of the central tube 3, the support plate 501 is moved downwards. During this process, the first locking block 702 is aligned with the clearance groove 503 and the locking frame 504 until the first locking block 702 engages with the clearance groove 503 and the locking frame 504. This completes the installation and coordination of the bearing platform 5 and the locking buckle 7. The bearing platform 5 is supported above the disassembly buckle 6. Then, the angle of the steel frame template is precisely inserted between the four bearing columns 4 fixed on the bearing platform 5. Finally, the top support 1 is inserted into the central tube 3 through the lower connecting pipe 2 to form the main support column, completing the support installation operation of the single steel frame template. When disassembling, the connection can be quickly released by reversing the operation to disassemble the buckle 6, achieving efficient turnover.
