Description

Technical Field

[0001] This utility model belongs to the field of steel structure construction protection, and specifically relates to a fall protection net structure for the construction of arched box beams. Background Technology

[0002] Steel structure buildings are a new type of building system that breaks down the boundaries between the real estate, construction, and metallurgical industries, integrating them into a new industrial system. This is the steel structure building system that is generally favored by industry insiders.

[0003] Compared to traditional concrete buildings, steel structure buildings use steel plates or profiles instead of reinforced concrete, resulting in higher strength and better earthquake resistance. Furthermore, because components can be factory-fabricated and installed on-site, construction time is significantly reduced. The reusability of steel greatly reduces construction waste, making it more environmentally friendly. Therefore, it is widely adopted by countries around the world in both industrial and residential buildings.

[0004] The steel structure mainly consists of supporting columns and steel beams. The steel beams are installed using butt welding along their length, which requires high-altitude butt welding. Therefore, fall protection nets need to be installed on the steel beams during welding. Currently, the method for installing fall protection nets on arched box beams is to weld an upward-facing hook on the side of the box beam and hook the fall protection net structure onto the hook. In some places, the steel beams are partially exposed, so the hook affects the overall appearance and needs to be removed later, which can damage the structural strength and is also quite troublesome.

[0007] By adopting the above technical solution, this application addresses the installation of fall protection nets on arched box girders, where the steel beams are partially exposed indoors. This is achieved by welding anti-slip guardrails onto the arched box girders, then placing wire rope loops on the arched box girders at the inner corners above the anti-slip guardrails. This method eliminates the need for welding hooks to the sides of the arched box girders, avoids subsequent cutting, facilitates construction, does not affect the quality of the arched box girders, and achieves good results.

The wire rope collar 2 is fitted onto the arched box girder 1, and the wire rope bolt 3 secures the wire ropes together to form a collar. The anti-slip guard 4 is fixedly welded to the top of the arched box girder 1. The wire rope collar 2 is located at the inside corner formed by the arched box girder 1 and the anti-slip guard 4. The fall protection net hook 5 and the fall protection mesh 6 are integrated, and the fall protection hook is attached to the bottom end of the wire rope sleeve.

[0024] This application addresses the installation of fall protection nets on arched box girders, where the steel beams are partially exposed indoors. By welding anti-slip guardrails 4 onto the arched box girder 1, and then placing wire rope loops 2 onto the arched box girder 1 at the inner corner above the anti-slip guardrails 4, the stability of the wire rope loops 2 is achieved. This eliminates the need for welding hooks to the sides of the arched box girder 1, avoids subsequent cutting, facilitates construction, does not affect the quality of the arched box girder 1, and achieves good results.

[0025] The wire rope bolt 3 includes a clamping plate 31, a U-bolt 32, and a locking nut 33. The clamping plate 31 has two through holes that mate with the U-bolt 32. The clamping plate 31 can also be shaped into a mountain-like undulation to form a special bolt for the wire rope. The wire rope is placed between the clamping plate and the U-bolt 32. The locking nut 33 is threaded to the side of the U-bolt 32 away from the wire rope, which can fix the wire rope into the wire rope bolt 3.
