Description

Technical Field

[0001] This utility model relates to the technical field of high-altitude connecting corridor construction platforms, and in particular to a high-altitude connecting corridor construction platform that is easy to disassemble and reuse. Background Technology

[0002] High-altitude corridor construction refers to the concrete pouring and shaping of an elevated corridor structure connecting different building structures in a high-altitude environment, through processes such as constructing temporary support platforms, installing main and secondary beams and formwork systems. Currently, for aesthetic and fire safety considerations, high-rise buildings often have one or more connecting corridors between adjacent high-rise buildings. The conventional method for supporting the concrete structure of such corridors involves erecting a steel platform, and then constructing a full-span steel pipe scaffold on the platform for formwork support.

[0003] An existing high-altitude concrete corridor construction formwork support platform (announcement number: CN221722237U) consists of several main steel beams installed between the existing crossbeams of two adjacent buildings, and several secondary I-beams spaced on the main steel beams to form the main support platform structure. However, the main beams and the pressure ring reinforcement, as well as the supporting I-beams and the crossbeams, are all fixedly connected. Therefore, dismantling requires damaging the embedded reinforcement and welded components, which not only leads to complicated dismantling and assembly and long time consumption, but also causes most of the materials to be unable to be reused, increasing material waste and construction costs. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an easily disassembled and reusable high-altitude corridor construction platform.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An easily detachable and reusable high-altitude connecting corridor construction platform includes several triangular trusses, steel bracket supports, and planks. The triangular trusses are horizontally arranged between two adjacent sets of steel bracket supports, and the two adjacent sets of triangular trusses are connected by I-beams. The I-beams are connected to the triangular trusses by high-strength bolts. The triangular trusses are fixedly connected to the steel bracket supports by high-strength bolts. High-strength bolts are threaded onto the steel bracket supports, and a steel plate pad passes through the end of the high-strength bolts away from the steel bracket supports.

[0007] As a further embodiment of this utility model, the scaffolding is distributed at equal intervals at the upper ends of several triangular trusses, and the scaffolding is fixedly connected to the triangular trusses by U-shaped rings.

[0008] As a further embodiment of this utility model, the upper end of the scaffold is fixed with an independent steel support by a connector, and the top of the independent steel support is fixed with a fork-shaped head support.

[0009] As a further embodiment of this utility model, a lower I-beam is embedded in the fork-shaped head support, and an upper I-beam is intersected at the upper end of the lower I-beam.

[0010] As a further embodiment of this utility model, the lower I-beam and the upper I-beam are fixedly connected by wire, and the adjacent independent steel supports are connected by a steel pipe, and the steel pipe is connected to the independent steel support by a fastener.

[0011] As a further embodiment of this utility model, a second steel pipe is provided at the upper end of the first steel pipe, and the second steel pipe is connected to the first steel pipe by a fastener.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In use, by setting up a triangular truss steel structure platform, each truss is prefabricated in the factory, ensuring component precision and connection quality. On-site high-altitude operations only involve high-strength bolt construction. Each triangular truss is connected by multiple sets of I-beams and high-strength bolts, and the triangular truss is fixed to the original structure with high-strength bolts, forming a stable overall platform. This not only improves construction efficiency and reduces high-altitude operation time but also enhances safety performance. By using independent steel supports and lower and upper I-beams to erect formwork support frames, the efficiency of formwork erection and dismantling can be effectively improved. This is suitable for the construction of corridor structures with multiple connecting corridors that require repeated erection and dismantling of formwork platforms. In addition, except for the pre-embedded sleeves, all other materials can be reused, resulting in less material loss and convenient assembly and disassembly, which can effectively improve construction efficiency and reduce labor costs.

[0022] Reference Figures 1-4 A high-altitude connecting corridor construction platform that is easy to assemble and disassemble includes several triangular trusses 1, steel bracket supports 2, and planks 3. Several triangular trusses 1 are horizontally arranged between two adjacent sets of steel bracket supports 2, and the two adjacent sets of triangular trusses 1 are connected by I-beams 101. The I-beams 101 are connected to the triangular trusses 1 by high-strength bolts. The triangular trusses 1 and the steel bracket supports 2 are fixedly connected by high-strength bolts 203. High-strength bolts 202 are threaded on the steel bracket supports 2, and a steel plate pad 201 passes through the end of the high-strength bolts 202 away from the steel bracket supports 2.

[0023] In use, the positioning sleeves of the triangular truss 1 are pre-embedded, and steel plate pads 201 are set at the floor slab positions as supports for the triangular truss 1. Positioning steel bracket supports 2 are pre-installed at the shear wall positions. The steel bracket supports 2 are installed using the steel plate pads 201 and high-strength bolts 202, thus serving as supports for the triangular truss 1. Afterwards, based on the dimensions of the connecting corridor and combined with stress calculations, the triangular truss 1 is fabricated and formed in the factory to ensure component accuracy and connection quality. Reinforcing bars are welded onto the triangular truss 1 for subsequent fixing of the independent steel supports 4. The fabricated sets of triangular trusses 1 are then transported to the construction site. Before hoisting the triangular truss 1, an independent steel support 4 is used to back the truss 1 on the floor directly below its support point. Then, a tower crane is used to hoist the single truss into place. Since the steel bracket support 2 has been pre-constructed at the shear wall location, the triangular truss 1 can be directly hoisted onto the steel bracket support 2. After that, high-strength bolts 202 are used to fix the triangular truss 1 to the concrete structure. The spacing of the triangular trusses 1 is determined according to the design stress. After the triangular trusses 1 are fixed, each triangular truss 1 is connected with an I-beam 101 and high-strength bolts 203. After the connection is completed, planks 3 are fully laid on the triangular truss 1, and safety netting is also laid to form a working platform. A protective railing is erected on the outermost perimeter using steel pipes. Independent steel supports 4 are erected on the platform, and lower and upper I-beams 7 and 8 are installed to form a formwork frame. Subsequently, structural construction such as laying the formwork for the connecting corridor, tying the reinforcing bars, and pouring concrete is carried out. Each set of triangular trusses 1 is welded in the factory, and the remaining connections are fixed with high-strength screws 202 and high-strength bolts 203, so that there is no welding work on site and the construction process will not cause environmental pollution.

[0024] In this embodiment, the scaffolding 3 is distributed at equal intervals at the upper ends of several triangular trusses 1, and the scaffolding 3 is fixedly connected to the triangular trusses 1 by U-shaped rings.

[0025] When in use, the plank 3 is made of wood and is fixed to the truss by a U-shaped ring. The U-shaped ring is connected to the truss, and the gap between the plank 3 and the U-shaped ring is filled with wooden wedges.

[0026] In this embodiment, an independent steel support 4 is fixed to the upper end of the scaffold 3 via a connector, and a fork-shaped head support 9 is fixed to the top of the independent steel support 4.

[0027] When in use, the steel plate pad 201 is placed at the floor slab and at the connection end between the steel bracket support 2 and the wall to distribute the load transmitted by the truss and bracket, and to avoid excessive local stress on the structure.

[0028] In this embodiment, a lower I-beam 7 is embedded in the fork-shaped top support 9, and an upper I-beam 8 is intersected at the upper end of the lower I-beam 7.

[0029] In use, HEB260, HEB160 and other steel profiles are connected by welding at the processing plant to form a triangular truss 1.

[0030] In this embodiment, the lower I-beam 7 and the upper I-beam 8 are fixedly connected by wire, and the adjacent independent steel supports 4 are connected by steel pipe 5, and the steel pipe 5 is connected to the independent steel supports 4 by fasteners.

[0031] In use, the fork-shaped head support 9 is fixed to the upper end of the independent steel support 4 and is used to connect the upper I-beam 8. The load is transferred to the steel support through the supporting beam, which plays the role of supporting and transmitting force.

[0032] In this embodiment, a second steel pipe 6 is provided at the upper end of the first steel pipe 5, and the second steel pipe 6 is connected to the first steel pipe 5 by fasteners.

[0033] In use, each group of independent steel supports 4 is connected by steel pipe 5. Steel pipe 5 and independent steel support 4 are connected by fasteners. Steel pipe 5 and steel pipe 6 are also connected by fasteners to enhance the overall stability of independent steel support 4.

[0034] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: First, before the lower structure concrete is poured, a sleeve is pre-embedded according to the positioning of the triangular truss 1 for the installation of through-wall bolts and through-floor bolts in subsequent construction. At the same time, a steel plate pad 201 is set at the floor position as a support for the triangular truss 1, and a positioning steel bracket support 2 is pre-installed at the shear wall position. The steel bracket support 2 is connected to the shear wall through the steel plate pad 201 and high-strength bolts 202, thus serving as a support for the triangular truss 1. Afterwards, according to the dimensions of the connecting corridor and combined with the stress calculation, the triangular truss 1 is processed and formed in the factory to ensure its component accuracy and connection quality. Reinforcing bars are welded on the triangular truss 1 for subsequent fixing of the independent steel support 4. Then, the processed triangular truss 1 is transported to the construction site. Before hoisting the triangular truss 1, independent steel supports 4 are used to back the truss 1 on the floor directly below its support point. The number of back supports is determined according to the design stress. Then, a tower crane is used to hoist the single truss into place. Since the steel bracket supports 2 have been pre-constructed at the shear wall location, the triangular truss 1 can be directly hoisted onto the steel bracket supports 2. After that, high-strength bolts 202 are used to fix the triangular truss 1 to the concrete structure. The spacing of the triangular trusses 1 is determined according to the design stress. After the triangular trusses 1 are fixed, each triangular truss 1 is connected with I-beams 101 and high-strength bolts 203. After the connection is completed, planks 3 are fully laid on the triangular truss 1, and safety netting is also laid to form a working platform. A protective railing is erected on the outermost perimeter using steel pipes. Independent steel supports 4 are erected on the platform, and lower and upper I-beams 7 and 8 are installed to form a formwork frame. Subsequently, the formwork for the connecting corridor is laid, the rebar is tied, and the concrete is poured. Once the structural construction is completed and the conditions for demolding are met, the formwork, lower I-beam 7, upper I-beam 8, independent steel support 4, scaffolding 3, platform connecting beams, etc. are removed in sequence. After the above demolition work is completed, pulleys and winches are installed. The triangular truss 1 is dismantled and hoisted by the cooperation of pulleys and winches so that the triangular truss 1 can be reused later.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
