Modular basket pull rod type disc type cantilevered scaffold

Abstract

The application discloses a modular flower basket pull rod type disc buckle type cantilever scaffold, and belongs to the technical field of cantilever scaffolds, which comprises a lower beam plate and an upper beam plate. In the application, an I-shaped steel is directly fixed on the lower beam plate through a steel fixing frame, a fixing hole and a fixing bolt, thereby forming a proximal support point of the cantilever structure, ensuring the stability of the root force, and enabling the I-shaped steel to be cantilevered outward from the lower beam plate only, so that a scaffold hole need not be reserved in a wall body during the whole construction process. The design of the steel fixing frame allows the position of the I-shaped steel to be fine-adjusted during installation, reduces the dependence on the precision of embedded parts, and reduces the force imbalance caused by initial positioning deviation. The distal end of the I-shaped steel is pulled and tied through a pull rope fixing ring, a metal steel rope and a pull rope lifting ring of the upper beam plate, thereby forming a three-dimensional force system with proximal force bearing and distal end pulling and tying, significantly improving the structural stability and construction safety, and being capable of providing a stable installation foundation for the protective scaffold and standing plate and providing all-around falling protection and operation boundary isolation for construction personnel.

Description

Technical Field

[0001] This application relates to the field of cantilever scaffolding technology, and in particular to a modular basket-link type disc-lock cantilever scaffolding. Background Technology

[0002] In modern construction, cantilevered scaffolding, a temporary construction facility that relies on a cantilevered structure extending outward from the edge of the building structure to support the external scaffolding, is widely used in high-altitude operations. Its core function is to transfer all or part of the scaffolding's load to the main building structure. However, in long-term practice, traditional cantilevered scaffolding has gradually revealed many practical problems that need to be solved due to inherent defects in its structural design and construction methods, seriously affecting construction quality, safety, and efficiency.

[0003] Traditional cantilevered scaffolding requires the cantilevered steel beams to pass directly through the building's exterior walls. This necessitates reserving scaffolding holes in the exterior walls during the early stages of construction. If these holes are not properly repaired during the later decoration phase, they can easily lead to potential leaks in the exterior walls. Furthermore, the installation of embedded parts, which are key components connecting the main structure and the cantilevered scaffolding, is frequently problematic in traditional construction. Such deviations can disrupt the stress balance of the scaffolding system, reducing structural stability and safety. Therefore, an improvement has been made to a modular basket-style tie rod disc-lock type cantilevered scaffolding. Utility Model Content

[0004] In view of the shortcomings of the prior art, this application provides a modular basket-style lever-type disc-lock type cantilever scaffolding, which overcomes the shortcomings of the prior art and aims to solve the problems in the prior art.

[0005] To achieve the above objectives, this application provides the following technical solution: a modular basket-style pull rod type cantilever scaffold, comprising a lower beam and an upper beam. A plurality of I-beams are evenly arranged along the length of the upper surface of the lower beam. An I-beam fixing frame is snapped onto the top of each I-beam. A fixing hole is formed through the upper surface of the fixing frame, and a fixing bolt is slidably inserted into the fixing hole. The I-beam fixing frame is fixedly installed on the lower beam by the fixing bolt. A rope fixing ring is fixedly welded to the lower surface of the I-beam away from the lower beam. A rope lifting ring is fixedly connected to the top of the upper beam, and a metal steel rope is fixedly connected between the rope lifting ring and the rope fixing ring. A protective footing is fixedly connected to the upper surface of the I-beam, and a standing plate is provided inside the protective footing on the upper surface of the I-beam.

[0006] By adopting the above technical solution, the I-beam is directly fixed to the lower beam slab through the I-beam fixing frame, fixing holes and fixing bolts, forming the near-end support point of the cantilever structure, ensuring the stability of the root. This allows the I-beam to cantilever outward from the lower beam slab without penetrating the building's exterior wall. No scaffolding holes need to be reserved in the wall during the entire construction process. Furthermore, the design of the I-beam fixing frame allows for fine-tuning of the I-beam's position during installation, reducing the reliance on the accuracy of embedded parts and minimizing stress imbalance caused by initial positioning deviations. The far end of the I-beam is connected to the upper beam slab through the rope fixing ring and metal steel rope, forming a three-dimensional force system with near-end bearing and far-end connection. This significantly improves structural stability and construction safety, providing a stable installation foundation for protective scaffolding and standing boards, and providing comprehensive fall protection and work boundary isolation for construction personnel.

[0007] As a preferred technical solution of this application, the protective footing includes several vertical rods, the bottom of each vertical rod is fixedly connected to a base plate, and the base plate is fixedly installed on an I-beam by mounting bolts. A disc is fixedly connected to the outer wall of each vertical rod near the upper end. A connecting hole is formed through the upper surface of the disc, and a connecting rod is provided between any two adjacent discs. Both ends of the connecting rod are fixedly connected to connectors, and the connecting rod is snapped onto the disc through the connectors. An insertion hole is formed inside the connector, and a wedge is slidably inserted into the insertion hole. The lower end of the wedge passes through the connector and the disc in sequence.

[0008] By adopting the above technical solution, the vertical rod is connected to the I-beam with bolts through the base plate to form the vertical support foundation of the protective scaffold. After the wedge is inserted into the insertion hole of the connector and the disc, a self-tightening connection is formed by hammering, and the connecting rod and the vertical rod can be assembled together to form a complete protective scaffold.

[0009] As a preferred technical solution of this application, the disk has eight connecting holes, and the eight connecting holes are arranged in a ring array on the disk.

[0010] By adopting the above technical solution, the eight annularly distributed connecting holes on the disk allow the disk to be connected to the connecting rod in multiple directions.

[0011] As a preferred technical solution of this application, the number of I-beams, rope lifting rings, rope fixing rings and metal steel ropes are the same and correspond one-to-one.

[0012] By adopting the above technical solution, it is ensured that each cantilevered I-beam is balanced by an independent tie system.

[0013] As a preferred technical solution of this application, the bottom of the standing plate is provided with a snap-fit ​​groove, and the standing plate is slidably snapped onto the I-beam through the snap-fit ​​groove, the width of the snap-fit ​​groove being adapted to the width of the I-beam.

[0014] By adopting the above technical solution, the snap-fit ​​groove at the bottom of the standing plate is adapted to the width of the I-beam, and tool-free installation is achieved through sliding snap-fit.

[0015] As a preferred technical solution of this application, warning boards are symmetrically connected to both sides of the upper surface of the standing board, and the outer surface of the warning boards is sprayed with brightly colored warning paint.

[0016] By adopting the above technical solution, the warning boards on both sides of the standing board are sprayed with high-contrast paint to clearly distinguish the work area from the danger boundary and reduce the misoperation of construction personnel.

[0017] As a preferred technical solution of this application, a protective net is bound to the outer side of the protective footing, and the protective net completely covers the gaps on the outer side of the protective footing.

[0018] By adopting the above technical solution, the protective netting covers the gaps on the outside of the protective scaffolding, preventing tools and materials from falling from the scaffolding and protecting the personnel and facilities below.

[0019] As a preferred technical solution of this application, the I-beam, I-beam fixing frame, vertical rod, base plate, disc, connecting rod, connector and wedge are all prefabricated parts in the factory.

[0020] By adopting the above technical solutions, standardized production and modular assembly can be achieved, which helps to save on-site construction time.

[0021] In summary, the beneficial effects of this application are as follows:

[0022] 1. In this application, the I-beam is directly fixed to the lower beam slab through I-beam fixing frames, fixing holes, and fixing bolts, forming the near-end support point of the cantilever structure. This ensures the stability of the root, allowing the I-beam to cantilever outward from the lower beam slab without penetrating the building's exterior wall. No scaffolding holes need to be pre-drilled in the wall during construction. Furthermore, the design of the I-beam fixing frames allows for fine-tuning of the I-beam's position during installation, reducing reliance on the accuracy of embedded parts and minimizing stress imbalance caused by initial positioning deviations. The far end of the I-beam is connected to the upper beam slab's rope hanging rings via rope fixing rings and metal steel ropes, forming a three-dimensional stress system with near-end bearing and far-end connection. This significantly improves structural stability and construction safety, providing a stable installation foundation for protective scaffolding and standing boards, and offering comprehensive fall protection and work boundary isolation for construction personnel.

[0023] 2. In this application, the vertical rod is connected to the I-beam with bolts through the base plate to form the vertical support foundation of the protective scaffold. After the wedge is inserted into the insertion hole of the connector and the disc, a self-tightening connection is formed by hammering, so that the connecting rod and the vertical rod can be assembled together to form a complete protective scaffold.

[0030] To make the technical means, creative features, objectives and effects of this application easy to understand, the following describes this application in conjunction with specific implementation methods.

[0031] like Figure 1 - Figure 4As shown, this embodiment provides a modular basket-style pull rod type cantilever scaffold, including a lower beam slab 1 and an upper beam slab 2. Several I-beams 3 are evenly arranged along the length of the upper surface of the lower beam slab 1. I-beam fixing frames 4 are snapped onto the top of each I-beam 3. Fixing holes 5 are drilled through the upper surface of the fixing frames 4, and fixing bolts 6 are slidably inserted into the fixing holes 5. The fixing frames 4 are fixedly installed on the lower beam slab 1 by the fixing bolts 6. A rope fixing ring 9 is fixedly welded to the lower surface of the I-beam 3 on the side away from the lower beam slab 1. A rope lifting ring 8 is fixedly connected to the top of the upper beam slab 2, and a metal steel rope 10 is fixedly connected between the rope lifting ring 8 and the rope fixing ring 9. A steel rope 10 is fixedly connected to the upper surface of the I-beam 3. The protective scaffold 7 has a standing plate 11 installed on the upper surface of the I-beam 3 inside it. In use, the I-beam 3 is directly fixed to the lower beam 1 through the I-beam fixing frame 4, fixing holes 5 and fixing bolts 6, forming the near-end support point of the cantilever structure, ensuring the root is stable. This allows the I-beam 3 to cantilever outward from the lower beam 1 without penetrating the building's exterior wall. The far end of the I-beam 3 is connected to the upper beam 2's rope hanging ring 8 through the rope fixing ring 9 and metal steel rope 10, forming a three-dimensional force system with near-end bearing and far-end connection. This significantly improves structural stability and construction safety, providing a stable installation foundation for the protective scaffold 7 and the standing plate 11, and providing all-round fall protection and work boundary isolation for construction personnel.

[0032] In this embodiment, as Figure 1 and 3 As shown, the protective bracket 7 includes several vertical rods 71, and each vertical rod 71 has a base plate 72 fixedly connected to its bottom. The base plate 72 is fixedly installed on the I-beam 3 by mounting bolts. A disc 73 is fixedly connected to the outer wall of the vertical rod 71 near its upper end. A connecting hole 74 is provided through the upper surface of the disc 73, and a connecting rod 75 is provided between any two adjacent discs 73. Both ends of the connecting rod 75 are fixedly connected to connectors 76, and the connecting rod 75 is engaged with the disc 73 through the connectors 76. The connector 76 has an insertion hole 77 inside, and a wedge 78 is slidably inserted into the insertion hole 77. The lower end of the wedge 78 passes through the connector 76 and the disc 73 in sequence. In use, the vertical rod 71 is bolted to the I-beam 3 through the base plate 72 to form the vertical support base of the protective footing 7. After the wedge 78 is inserted into the insertion hole 77 of the connector 76 and the disc 73, a self-tightening connection is formed by knocking, so that the connecting rod 75 and the vertical rod 71 can be assembled together to form a complete protective footing 7.

[0033] In this embodiment, as Figure 3As shown, the disk 73 has eight connecting holes 74, which are arranged in a ring array on the disk 73. In use, the eight ring-shaped connecting holes 74 on the disk 73 allow the disk 73 to be connected to the connecting rod 75 in multiple directions.

[0034] In this embodiment, as Figure 1 and 4 As shown, the number of I-beams 3, rope lifting rings 8, rope fixing rings 9, and metal steel ropes 10 are the same and correspond one-to-one. During use, ensure that each cantilevered I-beam 3 is balanced by an independent tie system to balance the load.

[0035] In this embodiment, as Figure 1 and 2 As shown, the bottom of the standing plate 11 is provided with a snap-fit ​​groove 12. The standing plate 11 is slidably snapped onto the I-beam 3 through the snap-fit ​​groove 12. The width of the snap-fit ​​groove 12 is adapted to the width of the I-beam 3. In use, the snap-fit ​​groove 12 at the bottom of the standing plate 1 is adapted to the width of the I-beam 3, and tool-free installation is achieved by sliding snap-fit.

[0036] In this embodiment, as Figure 2 As shown, warning boards 13 are symmetrically connected to both sides of the upper surface of the standing board 11, and the outer surface of the warning boards 13 is sprayed with brightly colored warning paint. When in use, the warning boards 13 on both sides of the standing board 11 are sprayed with high-contrast paint to clearly distinguish the work area from the danger boundary and reduce the misoperation of construction personnel.

[0037] In this embodiment, as Figure 1 As shown, a protective net 14 is tied to the outside of the protective scaffold 7, and the protective net 14 completely covers the gaps on the outside of the protective scaffold 7. When in use, the protective net 14 covers the gaps on the outside of the protective scaffold 7 to prevent tools and materials from falling from the scaffold and protect the personnel and facilities below.

[0038] In this embodiment, as Figure 1 and 3 As shown, the I-beam 3, I-beam fixing frame 4, vertical rod 71, base plate 72, disc 73, connecting rod 75, connector 76, and wedge 78 are all prefabricated parts in the factory. When in use, the standardized modular components can save on-site construction time.

[0039] The working principle of this application is as follows: When using the modular basket-style pull rod disc-lock type cantilever scaffolding of this application, the cantilever range of the scaffolding, the spacing of the I-beams 3, and the corresponding tie positions between the upper beam 2 and the lower beam 1 are determined according to the construction drawings. The installation points of the I-beams 3 and the rope lifting rings 8 are marked. The I-beams 3 are placed on the marked points of the lower beam 1, and the I-beam fixing frame 4 is clamped and placed on top of them. The fixing bolts 6 are inserted through the fixing holes 5 to fix the I-beams 3. The rope lifting rings 8 are fixedly installed at the marked positions on the top of the upper beam 2 corresponding to the lower beam 1, ensuring that they correspond to the cantilever direction of the I-beams 3. On the side of the lower surface of the I-beams 3 away from the lower beam 1, the metal steel rope 10 is connected through the rope fixing rings 9. The other end is tightened and fixed to the rope hanging ring 8 of the upper beam slab 2 to form a three-dimensional force system. Then, at the designated position on the upper surface of the I-beam 3, the vertical rod 71 is fixed by the base plate 72 and mounting bolts to form the vertical support frame of the protective footing 7. Along the height direction of the vertical rod 71, the connectors 76 at both ends of the connecting rod 75 are inserted into the discs 73 of the adjacent vertical rod 71 through the connecting holes 74 of the disc 73. The wedges 78 are inserted and hammered to make the connecting rod 75 rigidly connected to the vertical rod 71 to form a complete protective footing 7. The protective net 14 is tied to the outside of the protective footing 7. Then, the standing plate 11 is slidably attached to the I-beam 3 through the bottom snap-fit ​​groove 12 to form the working platform for the construction personnel. The working area is clearly marked by the warning plate 13.
