Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a cantilever netting device suitable for cantilevered I-beam scaffolding. Background Technology

[0002] As cantilever scaffolding technology is increasingly used in construction projects, scaffolding erection heights are also increasing. To ensure the safety of workers during scaffolding erection and high-altitude operations, horizontal cantilever nets are erected around the scaffolding to prevent falls from heights and falling objects.

[0003] However, traditional scaffolding requires daily inspection of fasteners, is prone to loosening when connected to the building, is difficult to construct, needs to be erected on specific floors, involves high-altitude work and carries the risk of falls, cannot be erected in rainy, snowy, or windy weather, has a cumbersome erection method, is difficult to fix, and has a high operational risk. At the same time, traditional processes are rough, have poor stability, and cannot meet increasingly stringent protection requirements. In particular, the excessive use of steel pipes is inconvenient and costly. Therefore, we propose a cantilever netting device suitable for cantilevered I-beam scaffolding. Utility Model Content

[0004] The purpose of this utility model is to provide a cantilever netting device suitable for cantilevered I-beam scaffolding, to solve the problems mentioned in the background art, such as the roughness and poor stability of traditional processes, which are difficult to meet the increasingly stringent protection requirements. To achieve the above objective, this utility model provides the following technical solution: A cantilever netting device suitable for cantilevered I-beam scaffolding includes several I-beam bodies arranged in a linear array. Two frame-type couplers are fixedly connected to the outer side of each I-beam body, with the two frame-type couplers respectively connected to the top and bottom of the I-beam body. Two fixing rings are fixedly connected to the top and bottom of each of the two frame-type couplers, and the two fixing rings are symmetrically distributed left and right. Two threaded rings are movably connected inside each frame-type coupler, and the two threaded rings are symmetrically distributed left and right. When using this device, the frame-type couplers are welded to the I-beam body through the cooperation of the fixing rings and the frame-type couplers. Fixing bolts are used to stably lock the fixing rings onto the couplers, resulting in strong overall stability. The device is also simple in structure and easy to operate, effectively solving the problem of cantilever netting arrangement for cantilevered scaffolding.

[0005] More preferably, the bottom of the frame-type fastener has two connecting grooves 1, which are symmetrically distributed from left to right, and the top of the fixing ring has a connecting groove 2. The interior of the connecting groove 2 is adapted to the interior of the connecting groove 1. The frame-type fastener and the fixing ring can be fixedly connected by fixing bolts, which effectively improves the convenience of the device.

[0006] More preferably, the connecting groove two and the connecting groove one are fitted with a fixing bolt inside. The outer side of the fixing bolt passes through the connecting groove two and is connected to the connecting groove one and the threaded ring one internally by thread. The fixing bolt makes the fixing ring stably locked on the fastener, which has strong overall stability and effectively improves the safety of the device.

[0007] More preferably, the outer side of the fixing bolt is threaded with a threaded ring II, and the inside of the fixing ring is movably connected with a steel pipe. By inserting the steel pipe into the fixing rings on both sides, the steel pipe can be fixedly installed at the upper and lower flanges of the I-beam. Utilizing the characteristics of the upper and lower flanges of the I-beam, the steel pipe is tilted at an angle, which can prevent objects and people from rolling down when working at heights.

[0008] In a further preferred embodiment, a steel wire rope is fixedly connected to the outside of the steel pipe, and the outside of the steel wire rope is fixedly connected to the back of the I-beam body. A safety net is fixedly connected to the inside of the steel wire rope. The safety net is fixed to the step on the I-beam by the steel wire rope to prevent objects from sliding off the outside of the structure and reduce the danger of working at height.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] In this utility model, when using the device, the frame-type fastener is welded to the I-beam body by the cooperation of the fixing ring and the frame-type fastener. The fixing ring can be stably locked on the fastener by the fixing bolt. The overall stability is strong. At the same time, the structure is simple and the operation is convenient. It can effectively solve the problem of cantilevered scaffolding cantilever netting arrangement.

[0011] In this invention, during protective work, a steel pipe is inserted into the fixing rings on both sides, allowing the steel pipe to be fixedly installed at the upper and lower flanges of the I-beam. Utilizing the characteristics of the upper and lower flanges of the I-beam, the steel pipe is tilted at an angle, which can prevent objects and people from rolling down during high-altitude operations. At the same time, connecting the horizontal net to the I-beam platform can effectively prevent objects from sliding outwards, reducing the danger of working at heights. Attached Figure Description
