Description

Technical Field

[0001] This utility model relates to the technical field of formwork support systems, specifically a connecting accessory, a side wall support mechanism, and a disc-lock scaffolding system. Background Technology

[0002] With the widespread application of scaffolding in building construction, pressing issues have emerged: in underground structures, individual buildings, or in tunnel and box culvert construction, walls of a certain thickness exist around the perimeter or inside the building structure due to factors such as building function and structural design. In traditional construction, these side walls are constructed in stages with the beam and slab structure, mainly in two phases. One method involves first reinforcing the side wall formwork with steel pipe couplers and water-stop bolts, then using diagonal bracing for anti-tipping measures. After the overall reinforcement of the side wall formwork is completed, the side wall concrete is poured. The formwork and reinforcement system can only be removed after the concrete strength reaches the removal threshold. During the removal of the formwork and reinforcement system, the formwork system for the beam and slab structure is constructed concurrently. Finally, the beam and slab structure is poured, combining with the side wall to form a complete structure. The other method uses steel formwork for the side walls. The main difference between the two methods is the material used for the side wall formwork; the subsequent construction processes are basically similar. However, steel formwork is relatively heavy, making adjustment difficult and costly. Whether it is side wall formwork or steel formwork, the side wall and beam-slab structure need to be constructed in stages, which greatly extends the construction period. In addition, the materials used for different formwork reinforcement measures cannot be used in a compatible manner, which increases the types of materials and management costs. Utility Model Content

[0003] To address the shortcomings of the existing technology, this utility model provides a connecting accessory, a side wall support mechanism, and a disc-lock scaffolding system, which can ensure the synchronous construction of the side wall and the beam-slab structure while ensuring safe construction, thereby improving construction efficiency.

[0004] To achieve the above objectives, this utility model provides a connecting accessory, including a connecting main beam, a connector and a first pin, wherein the connecting main beam is a hollow tubular structure, and the first end of the connector is fixedly connected to the first end of the connecting main beam; The second end of the connector is provided with a slot for embedding the upright wheel disc of the disc buckle bracket system; The connector is provided with a through groove that extends vertically through the connector and intersects with the slot. The first pin is inserted into the through groove.

[0005] In one embodiment, the first pin has a knife-shaped structure that is wide at the first end and narrow at the second end; the first end of the first pin is located above the connector, and the first end of the first pin is wider than the length of the through groove; the second end of the first pin is located below the connector, and the second end of the first pin is narrower than the length of the through groove.

[0006] In one embodiment, the second end of the first pin is provided with a through hole, and a second pin is provided on the through hole. The portion of the through groove above the slot is defined as the first slot, and the portion of the through groove below the slot is defined as the second slot. The length of the second pin is greater than the width of the first slot, and the length of the second pin is less than the width of the second slot.

[0007] In one embodiment, the connector is fixedly connected to the connecting main beam by welding.

[0008] To achieve the above objectives, this utility model also provides a side wall support mechanism, including a bracket and the aforementioned connecting accessories, wherein the bracket includes a screw, an adjusting nut and a top support; The first end of the screw is embedded in the second end of the connecting main beam, the top support is fixedly provided on the second end of the screw, and the adjusting nut is threadedly connected to the screw.

[0009] In one embodiment, the adjusting nut has a handle on its side.

[0010] To achieve the above objectives, this utility model also provides a disc-lock scaffolding system, characterized in that it includes several of the above-mentioned side wall support mechanisms for supporting the main keel of the side panel template; The connecting fittings on the side wall support mechanism are connected to the upright wheel disc on the disc-lock scaffolding system via the connector and the first pin, and the top support on the side wall support mechanism abuts against the main keel of the side panel template.

[0011] Compared with the prior art, the present invention has the following beneficial technical effects: The connecting fitting in this invention features a slot on the connector head, allowing the upright wheel disc of the disc-lock scaffold system to be embedded in the slot. A through groove intersecting the slot is also provided on the connector head, allowing the first pin to pass through the connector head and the upright wheel disc, thus connecting and fixing the connecting fitting to the upright wheel disc. Furthermore, a top support is connected to the connecting fitting via a screw and adjusting nut, integrating two systems with different functions. In beam and slab structures, the disc-lock scaffold provides normal support. When reinforcing side walls, the top support provides abutment support to the main keel of the side panel formwork along the wall height. This not only saves on reinforcement materials such as water-stop screws and diagonal braces but also avoids drilling holes in the wall formwork, reducing material waste. Compared to existing steel formwork, it is easier to operate and adjust, significantly reducing material input, management, and construction costs, and improving installation efficiency.

[0021] Example 1 like Figure 1 , Figure 2The diagram shows a connecting accessory disclosed in this embodiment, which mainly includes a connecting main beam 1, a connecting head 2, and a first pin 3. The connecting main beam 1 is a hollow tubular structure made of steel, and the first end of the connecting head 2 is fixedly connected to the first end of the connecting main beam 1. The second end of the connecting head 2 has a slot 201 for embedding the upright wheel disc of the disc-lock bracket system. Simultaneously, the connecting head 2 has a through groove 202 that extends vertically through the connecting head 2 and intersects with the slot 201. The first pin 3 is inserted into the through groove 202. By creating the slot 201 on the connecting head 2, the upright wheel disc of the disc-lock bracket system can be embedded in the slot 201. Simultaneously, by providing the through groove 202 intersecting with the slot 201 on the connecting head 2, the first pin 3 can pass through the connecting head 2 and the upright wheel disc, thereby connecting and fixing the connecting accessory to the upright wheel disc, and thus enabling direct integration of the connecting accessory into the existing disc-lock bracket system.

[0022] In this embodiment, the first pin 3 has a knife-shaped structure with a wider first end and a narrower second end. Both the first pin 3 and the connector 2 are steel components. The thickness of the first pin 3 is less than the minimum groove width of the through groove 202. The first end of the first pin 3 is located above the connector 2, and the width of the first end of the first pin 3 is greater than the maximum groove length of the through groove 202. The second end of the first pin 3 is located below the connector 2, and the width of the second end of the first pin 3 is less than the minimum groove length of the through groove 202. Preferably, the second end of the first pin 3 has a through hole 301, and a second pin is fixedly mounted on the through hole 301 to ensure that the first pin 3 will not fall off the connector 2 when not in operation.

[0023] Specifically, the length direction of the second pin is parallel to the thickness direction of the first pin 3. The portion of the through groove 202 above the slot is defined as the first slot 2021, and the portion of the through groove 202 below the slot is defined as the second slot 2022. The length of the second pin 3 is greater than the minimum slot width of the first slot 2021, and the length of the second pin 3 is less than the minimum slot width of the second slot 2022. That is, the second pin 3 can pass through the second slot 2022 but cannot pass through the first slot 2021. This allows the first pin to be pulled out of the slot 201 while maintaining the connection with the connector 2, so that the first pin 3 will not fall off the connector 2 when not in operation.

[0024] In this embodiment, the connector 2 and the connecting main beam 1 are fixedly connected by welding. In specific applications, bolt connections, snap-fit ​​connections, or other methods can also be used to fix the connector 2 and the connecting main beam 1.

[0025] Example 2 like Figure 3The diagram shows a side wall support mechanism disclosed in this embodiment, which mainly includes a bracket and the connecting accessories from Embodiment 1. The bracket includes a screw rod 5, an adjusting nut 6, and a top support 7. The first end of the screw rod 5 extends into the connecting main beam 1 from the second end of the connecting main beam 1. The top support 7 is fixedly mounted on the second end of the screw rod 5. The adjusting nut 6 is threaded onto the screw rod 5 and abuts against the second end of the connecting main beam 1. That is, the screw rod 5, the connecting main beam 1, and the adjusting nut 6 form a telescopic screw pair, thereby enabling the side wall support mechanism to have a telescopic stroke, allowing it to abut and support the main keel of the side panel formwork in construction environments with different space sizes.

[0026] In the specific implementation process, the side of the adjusting nut 6 is provided with two symmetrical handles 601, so as to turn the adjusting nut 6 so that the top support 7 can press against the main keel of the side plate template.

[0027] Example 3 This embodiment discloses a disc-lock scaffolding system, which includes several side wall support mechanisms 8 as in Embodiment 2, used to support the main keel of the side panel template. The connecting accessories on the side wall support mechanism 8 are connected to the upright wheel disc of the disc-lock scaffolding system through connectors and first pins. The top support on the side wall support mechanism 8 abuts against the main keel of the side panel template.

[0028] refer to Figure 4 In this embodiment, the disc-lock scaffolding system comprises a full-span scaffold consisting of multiple uprights 9, multiple horizontal bars 10, multiple vertical diagonal bars 11, and multiple U-shaped top supports 12. The disc-lock full-span scaffolding provides normal support at beam and slab structures. After the full-span scaffolding is deployed to the junction of the side walls, and the secondary joists of the side wall formwork are fixed, the main joists of the side wall formwork are laid. The main joists are supported by the side wall support mechanism 8 connected to the upright wheel disc 4 adjacent to the main joists of the side wall formwork. The side wall support mechanism 8 transmits lateral force to the full-span scaffolding, effectively meeting its anti-overturning and verticality requirements. This eliminates the need for traditional side formwork diagonal bracing anti-overturning measures, saving on reinforcement materials such as tie rods / waterstop rods and diagonal braces, and avoiding the need to drill holes in the wall formwork. In addition, the horizontal bars 10 at the 8 connected uprights 9 of the side wall support mechanism are fully installed to serve as a passage for construction. At the same time, the horizontal bars 10 are also densified in some areas to avoid local deformation of the scaffolding due to large lateral forces during the synchronous pouring of the side wall.

[0029] In practical implementation, at the intersection of the side wall and the beam-slab structure, there may be localized haunches. U-shaped top supports 12, combined with steel pipes of a certain length, can be used for diagonal bracing. The ends of the steel pipes are connected to the horizontal bars 10 of the full-span scaffold. This completes the formwork support for the haunches. The disc-lock scaffolding system in this embodiment allows for simultaneous side formwork construction and beam / slab structure construction. Compared to traditional step-by-step construction methods, it saves significant construction time and eliminates the need to alter the original support method of the disc-lock scaffolding system. By using the side wall support mechanism 8, the investment in materials such as tie rods / waterstop tie rods and side wall braces is reduced, along with corresponding construction procedures, significantly reducing material costs and time. Compared to traditional steel formwork, it is also easier to operate and adjust, greatly reducing management and construction costs and improving installation efficiency. Furthermore, the side wall support mechanism 8 has advantages such as simple and compact structure, easy fabrication and assembly, stable and reliable connection, and quick and convenient use.
