Description

Technical Field

[0001] This utility model relates to the field of formwork assembly technology, specifically a rapid assembly building formwork. Background Technology

[0002] Construction formwork is a temporary support structure used to ensure the quality and safety of concrete projects, accelerate construction progress, and reduce project costs. Existing construction formwork is generally assembled from columns and crossbars.

[0003] Existing crossbars are connected to the uprights using fasteners such as double U-shaped or cross-shaped fasteners. However, in practice, most fasteners rely on bolts and eccentric friction to stabilize the crossbars. This method suffers from unstable connections, a tendency to slip and displace, and cumbersome assembly and disassembly, resulting in high labor intensity for workers. Therefore, those skilled in the art have developed a rapidly assembling building formwork to address the problems mentioned in the background section. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a quick-assembly building formwork to solve the problem that existing methods of connecting crossbars to columns via double U-shaped fasteners or cross fasteners have problems such as unstable connections, easy slippage and displacement, cumbersome disassembly and assembly, and high labor intensity for workers.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a quick-assembly building formwork, comprising uprights and crossbars. The uprights have threaded grooves, and support rings are fitted around the threaded grooves. The support rings have insertion holes. The crossbars have grooves at both ends, and insertion rods are installed in the grooves. The insertion rods have through holes. A movable groove is formed on one side of the grooves. A positioning block is provided in the movable groove. A limit rod is installed at the end of the positioning block away from the insertion rod. A spring is fitted around the periphery of the limit rod. A limit hole is formed on the side of the movable groove facing the spring.

[0008] Preferably, the support ring has a threaded strip in the middle, and the support ring is threadedly connected to the upright through the threaded strip. Since the support ring is threadedly connected to the upright, the height of the support ring can be adjusted by rotating the support ring, thereby adapting to different crossbar assembly heights.

[0009] Preferably, the insertion rod is inserted into the support ring through the insertion hole, thereby assembling the crossbar and the upright.

[0010] Preferably, the positioning block is inserted into the insertion rod through a through hole. After the positioning block and the insertion rod are inserted, the positioning block can limit the insertion rod inserted into the insertion hole to prevent the insertion rod from coming loose from the insertion hole. This connection method solves the problem of slippage and instability that occurs after the traditional mold frame is assembled.

[0011] Preferably, the limiting rod is slidably inserted into the limiting hole, one end of the spring is pressed against the positioning block, and the other end of the spring is pressed against the inner wall of one side of the movable groove. When the crossbar is disassembled or assembled, the positioning block is pressed into the movable groove, causing the limiting rod to move into the limiting hole. At this time, the spring is compressed, and the positioning block is disengaged from the through hole on the rod. Then the crossbar is lifted upward, thereby achieving the effect of separating the crossbar from the upright. This structure allows for quick disassembly and assembly without the need for bolts.

[0012] Preferably, the bottom side of the positioning block is provided with anti-slip texture to increase the friction when the operator moves the positioning block and improve the safety when moving the positioning block.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a building formwork that can be assembled quickly, and has the following beneficial effects:

[0015] The design incorporates an adjustable-height support ring threaded onto the upright, with insertion holes on the support ring. The crossbar has grooves at both ends for inserting rods. Aligning the rods with the insertion holes on the support ring completes the assembly of the crossbar and upright. Subsequently, a spring-loaded positioning block engages with the through-hole on the rod, securing it and preventing loosening between the crossbar and upright. Since the support ring and upright are threaded together, slippage is prevented, ensuring the crossbar will also remain secure. To disassemble or assemble the crossbar, the positioning block is pressed into the movable groove, causing the limiting rod to move into the limiting hole. This compresses the spring and disengages the positioning block from the through-hole on the rod. The crossbar is then lifted upwards, separating it from the upright. This structure allows for quick assembly and disassembly without the need for bolts. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides a technical solution: a rapid assembly building formwork. (Please refer to...) Figure 1 , Figure 3 , Figure 4 , Figure 5 The system includes an upright post 1 and a crossbar 6. The upright post 1 has a threaded groove 2, and a support ring 3 is fitted around the threaded groove 2. The support ring 3 has an insertion hole 5. The crossbar 6 has grooves 7 at both ends, and an insertion rod 8 is installed in the groove 7. The insertion rod 8 has a through hole 9. The groove 7 has a movable groove 10 on one side, and a positioning block 11 is provided in the movable groove 10. A limit rod 13 is installed at the end of the positioning block 11 away from the insertion rod 8. A spring 14 is fitted around the periphery of the limit rod 13. The movable groove 10 has a limit hole 15 on the side facing the spring 14.

[0024] Please see Figure 2 , Figure 3 , Figure 4 , Figure 5The support ring 3 has a threaded strip 4 in the middle, and the support ring 3 is threadedly connected to the upright 1 through the threaded strip 4. Since the support ring 3 is threadedly connected to the upright 1, the height of the support ring 3 can be adjusted by rotating the support ring 3, thus adapting to the assembly height of crossbars 6 of different heights. The insertion rod 8 is inserted into the support ring 3 through the insertion hole 5, thereby assembling the crossbar 6 and the upright 1. The positioning block 11 is inserted into the insertion rod 8 through the through hole 9. When the positioning block 11 is inserted into the insertion rod 8, the positioning block 11 can limit the insertion rod 8 inserted into the insertion hole 5, preventing the insertion rod 8 from coming loose from the insertion hole 5. This connection method solves the problem of transmission After assembly, the mold frame experiences slippage and instability. The limiting rod 13 is slidably inserted into the limiting hole 15. One end of the spring 14 is pressed against the positioning block 11, and the other end of the spring 14 is pressed against the inner wall of the movable groove 10. When disassembling and assembling the crossbar 6, the positioning block 11 is pressed into the movable groove 10, causing the limiting rod 13 to move into the limiting hole 15. At this time, the spring 14 is compressed, and the positioning block 11 disengages from the through hole 9 on the insert rod 8. Then, the crossbar 6 is lifted upward, thereby achieving the effect of separating the crossbar 6 from the upright rod 1. This structure allows for quick disassembly and assembly without the need for bolt fixation.

[0025] Please see Figure 4 The bottom side of the positioning block 11 is equipped with anti-slip texture 12, which increases the friction when the operator moves the positioning block 11 and improves the safety when moving the positioning block 11.

[0026] The building formwork in this utility model consists of uprights 1 and crossbars 6. Threaded grooves 2 are provided on the uprights 1, and support rings 3 are fitted on the threaded grooves 2. The support rings 3 are threadedly connected to the uprights 1 with the threaded grooves 2 through the threaded strips 4 in the middle. Since the support rings 3 are threadedly connected to the uprights 1, the height of the support rings 3 can be adjusted by rotating the support rings 3, so as to accommodate the assembly height of crossbars 6 of different heights.

[0027] Multiple insertion holes 5 are provided on the support ring 3 to correspond to multiple directions. Grooves 7 are provided at both ends of the crossbar 6, and insertion rods 8 are installed in the grooves 7. When assembling the crossbar 6 and the upright 1, the positioning block 11 in the movable groove 10 on the crossbar 6 is moved away from the end of the insertion rod 8. Then, the end of the crossbar 6 with the groove 7 is inserted from top to bottom into the side of the support ring 3 with the insertion hole 5, so that the insertion rod 8 is inserted into the insertion hole 5 on the support ring 3. Then, the positioning block 11 is released, and the positioning block 11 is inserted into the through hole 9 on the insertion rod 8 under the action of the spring 14. When the positioning block 11 is inserted into the insertion rod 8, the positioning block 11 can limit the insertion rod 8 inserted into the insertion hole 5 to prevent the insertion rod 8 from coming loose from the insertion hole 5. This connection method solves the problem of slippage and instability that occurs after the traditional mold frame is assembled.

[0028] When disassembling and assembling the crossbar 6, the positioning block 11 is pressed into the movable groove 10, causing the limiting rod 13 to move into the limiting hole 15. At this time, the spring 14 is compressed, and the positioning block 11 disengages from the through hole 9 on the insert rod 8. Then, the crossbar 6 is lifted upward, thereby achieving the effect of separating the crossbar 6 from the upright rod 1. This structure allows for quick disassembly and assembly without the need for bolts.
