Description

Technical Field

[0001] This utility model relates to safety devices for cantilevered scaffolding in construction engineering, and in particular to a simple cantilevered scaffolding safety device. Background Technology

[0002] After the cantilevered scaffolding I-beams are laid, high-altitude external scaffolding erection work is required. The lifeline is mainly used to suspend the safety belts of the operators to ensure the personal safety of the workers.

[0003] Currently, most existing lifelines for cantilever scaffolding construction are fixed to the uprights of the external scaffolding. While this serves as an insurance measure during the erection of the external scaffolding, it lacks early-stage safety protection. The lifeline can only be installed after a portion of the external scaffolding has been erected, leading to significant safety hazards during the early stages of scaffolding construction. Therefore, we propose a simplified safety device for cantilever scaffolding. Utility Model Content

[0004] The purpose of this utility model is to provide a simple safety device for cantilever scaffolding. Its structure is reasonable and can solve the problem of inadequate safety protection in the early stage of the current cantilever scaffolding erection. It is easy and convenient to install and dismantle.

[0005] The purpose of this utility model is achieved as follows: A simple cantilever scaffolding safety device includes a cantilever scaffolding. The top of the upright is provided with a fixing hole for inserting a steel wire rope. The bottom of the upright is fixed to a rectangular base. Through holes are provided at the four corners of the base. Two symmetrical U-shaped screws pass through the base to fix and connect the cantilever I-beams. The U-shaped screws open upwards and pass through two holes on one side of the base from bottom to top. The arc-shaped bottom of the U-shaped screws is located at the bottom of the base and is stuck between the two holes, thus securing the cantilever I-beams. The two ends of the U-shaped screws passing through the base are fastened with round washers and fastening nuts. The steel wire rope for suspending the safety belt passes through the fixing holes between the two uprights and is fixed.

[0006] This utility model includes a No. 14 I-beam upright, a steel plate with an elliptical hole welded to the lower part of the upright as a base, U-bolts, washers, and nuts.

[0007] The I-beam uprights are high in strength and can effectively resist the impact force transmitted from the lifeline.

[0008] The bottom of the I-beam upright has a firmly welded steel plate with oval holes, which can effectively resist the impact transmitted from the upright.

[0009] At the bottom of the I-beam upright, two sets of U-bolts are used to pass through the steel plate base to reliably connect the upright to the cantilevered I-beam of the original cantilevered scaffold, which can ensure the firmness and stability of the upright connection.

[0010] The uprights are connected to the ends of the cantilevered I-beams via U-bolts, and the spacing between the uprights can be adjusted according to the actual site conditions, making them flexible in use.

[0011] The uprights are connected to the ends of the cantilevered I-beams via U-bolts. The uprights can be installed before the cantilevered I-beams are in place, allowing the high-altitude lifeline to be erected early in the construction of the external scaffolding.

[0012] Working principle: First, workers mark the centerline position of the upright as specified in the design drawings at the end of the original cantilevered I-beam. The upright is a No. 14 I-beam for easy loading and unloading. The upright is placed on the centerline, and the end of the original I-beam is fixed to the steel plate at the bottom of the upright using U-bolts. The steel plate at the bottom of the upright is welded to the upright at the factory, so workers do not need to consider the technical process of fixing the bottom steel plate. Depending on the actual site conditions, another upright is fixed at a certain interval at the end of the original cantilevered I-beam. After the number of uprights meets the site requirements, a steel wire rope is laid through the pre-drilled holes at the top of the upright as a lifeline for high-altitude operations. The safety belts of the construction workers are suspended from the steel wire rope to ensure their safety. Beneficial effects

[0013] 1. This utility model achieves the function of adapting to different models of cantilevered I-beams by leaving elliptical holes in the steel plate at the bottom of the upright, thus expanding its application range.

[0014] 2. This utility model uses U-bolts to connect with the original I-beams, allowing the uprights to be installed before the cantilevered I-beams are hoisted, thus solving the problem of delayed lifeline erection in the early stages of scaffolding operations. Attached Figure Description
