Description

Technical Field

[0001] The present invention relates to the technical field of scaffolding engineering, and particularly relates to an attachment structure for a building facade operation scaffolding and a construction method thereof. Background Art

[0002] With the rapid development of infrastructure in China, many new types of wall connecting members for external scaffolding are widely used in building construction, municipal engineering, and various activities as temporary structures. At present, the domestic application of scaffolding wall connecting structures mainly includes embedded steel pipe and fastener steel pipe wall connecting structures, embedded round steel and welded steel pipe wall connecting structures, embedded sleeve bolt and fastener wall connecting structures, guy ropes, column hugging, etc.

[0003] For the embedded steel pipe and fastener steel pipe wall connecting structure: Before pouring concrete for the floor beam slab, short steel pipes are embedded at the floor edge in the beam or floor slab. After pouring concrete, another short steel pipe is used to connect with the external scaffolding, and the two short steel pipes are then connected by right-angle fasteners. This method belongs to the traditional construction method of wall connecting structures, and the problems are as follows: First, the steel pipe cannot be directly disassembled. In actual applications, multiple short steel pipes need to be embedded along the direction of the floor edge to form multiple wall connecting structures connected to the external scaffolding. When external wall masonry and plastering are required, multiple holes need to be reserved on the external wall for the multiple steel pipes. On the one hand, these holes need to be repaired and filled later, and this type of wall connecting structure is very likely to cause quality problems such as water seepage and leakage, and wall cracking on the external wall. On the other hand, it affects construction efficiency and leads to a longer construction period. Second, during curtain wall installation construction, to ensure the stability of the external scaffolding, the wall connecting structure needs to be removed and supplemented. However, when removing this type of wall connecting structure, the embedded short steel pipes need to be cut by hot work or electric saw, increasing the safety hazards and construction steps at the construction site.

[0004] For the embedded round steel and welded steel pipe wall connecting structure: Before pouring concrete for the floor beam slab, short round steel is embedded at the floor edge in the beam or floor slab. After pouring concrete, another short steel pipe is used to connect with the external scaffolding, and the short steel pipe and the short round steel are then connected by welding. The problems of this method are as follows: First, the steel pipe cannot be directly disassembled. In actual applications, multiple short steel pipes need to be embedded along the direction of the floor edge to form multiple wall connecting structures connected to the external scaffolding. When external wall masonry and plastering are required, multiple holes need to be reserved on the external wall for the multiple steel pipes. On the one hand, these holes need to be repaired and filled later, and this type of wall connecting structure is very likely to cause quality problems such as water seepage and leakage, and wall cracking on the external wall. On the other hand, it affects construction efficiency and leads to a longer construction period. Second, during curtain wall installation construction, to ensure the stability of the external scaffolding, the wall connecting structure needs to be removed and supplemented. However, when removing this type of wall connecting structure, the embedded short steel pipes need to be cut by hot work or electric saw, increasing the safety hazards and construction steps at the construction site.

[0005] For the embedded sleeve bolt fastener type wall connection structure: Before pouring concrete for the floor slab and beam, drill holes in the formwork at the edge of the floor. Align the sleeve with the hole position and fix it stably. After the concrete is poured and reaches a certain strength requirement, screw one end of the bolt tightly into the sleeve, and then use a fastener to lock and connect the other end of the screw rod with the cross bar of the external scaffolding. The problems existing in this wall connection structure are as follows: Since only one fastener is used to lock and connect the screw rod with the cross bar of the external scaffolding, and the anti-slip ability of the fastener cannot meet the wind load requirements of the external scaffolding on floors with relatively high storeys, the structural stability of the external scaffolding is poor and cannot meet the requirements.

[0006] For the stay brace: Connect the upper end of the inclined rod to the external scaffolding by using a fastener, add a cross bar at the lower end of the inclined rod, and connect the cross bar to the external scaffolding and the lower end of the inclined rod by using a fastener to finally form a triangular stable system. For the external scaffolding of super high-rise buildings, multiple cross bars can be added. The problems existing in this wall connection method are as follows: First, when demolishing this type of wall connection structure, for the embedded short steel pipes, hot work cutting or electric saw cutting is required, which increases the safety hazards at the construction site. Second, for the external scaffolding of super high-rise buildings, in order to ensure the stability of the external scaffolding, stay braces need to be set for each bay, which increases the workload and safety hazards, with low construction efficiency and long construction period.

[0007] For the column clamping: At the position of the side column on the floor, connect the fastener-type steel pipes into a rectangle by using fasteners, clamp the side column tightly, and then connect it to the external scaffolding through two extended steel pipes. The problems existing in the construction method of this wall connection structure are as follows: First, when there is masonry and plastering of the external wall, since the external scaffolding is still required as a protective measure, the column clamping cannot be demolished, and holes need to be reserved for the steel pipes of the column clamping. These holes are repaired and filled later. This type of construction method of the wall connection structure is very likely to cause quality problems such as water seepage and leakage of the external wall and wall cracking. At the same time, there are also problems of low construction efficiency and long construction period.

[0008] In addition, for buildings with too large storey heights, the above-mentioned wall connection structure layouts cannot meet the specification requirements. According to Article 5.2.8 of the "Safety Technical Code for Fastener Steel Pipe Scaffolds in Construction" (JGJ130 - 2011), the maximum vertical distance of the wall connection structure layout is 3 steps. Calculated at 1.8 m per step, the height of 3 steps = 3×1.8 = 5.4 m. Therefore, when the storey height is greater than 5.4 m (for example, the storey height is 10 m and the vertical distance of the wall connection structure is 10 m), the above-mentioned wall connection structure layouts cannot meet the specification requirements, and at the same time, the calculation formulas in Article 5.2.8 and Article 5.2.9 of the specification will no longer conform to the actual conditions.

[0009] Therefore, it is necessary to provide at least one attachment structure for the scaffolding for building facade operations, which can effectively improve the construction efficiency and safety while stably strengthening the external scaffolding, and provide a construction method for this attachment structure for the scaffolding for building facade operations. Summary of the Invention

[0010] The first object of the present invention is to provide an attachment structure for a scaffolding for building facade operations, which can effectively improve the construction efficiency and safety while stably reinforcing the external scaffolding system, and can avoid quality problems such as water seepage, leakage, and cracking of the external wall.

[0011] The second object of the present invention is to provide a construction method for an attachment structure for a scaffolding for building facade operations, which can stably reinforce the external scaffolding system, and can effectively improve the construction efficiency and safety, and can avoid quality problems such as water seepage, leakage, and cracking of the external wall.

Each anchoring assembly 2 is correspondingly connected with a connecting assembly 3.

Secondly, because there are no measures such as wall connecting members, bracing, and column hugging, and both the anchoring assembly 2 and the connecting assembly 3 can be directly disassembled, it will not cause obstacles to the construction of bricklaying, plastering and curtain wall installation. Therefore, the interspersed construction of bricklaying, plastering and curtain wall installation can be accelerated, the construction period can be saved, and the construction efficiency can be improved. Moreover, since the attached structure 100 of the construction exterior wall operation scaffolding of the present invention is mainly connected to the column 201 of the building, there is no need to set a large number of wall connecting members on the floor, and it will not cause quality problems such as water seepage, leakage and cracking of the external wall.
