Description

Technical Field

[0001] The present invention relates to the technical field of safety protection and the installation of horizontal lifelines for steel structures, and particularly to a fixture for fixing a steel wire rope to a lifeline. Background Art

[0002] Currently, in the field of installing horizontal lifelines for steel structures, especially during the construction of steel structure addition floors, the lifeline cannot be generated synchronously with the first-line hoisting operation. Instead, after the main structure framework is hoisted and formed, secondary-line personnel walk between the beams and columns without safety protection measures, weld pull rings on the load-bearing columns according to the splicing direction of the steel beams, and then workers installing the lifeline pass the lifeline through the pull rings and fix it with buckles. Since the lifeline cannot follow the first line synchronously, many operators for secondary-line operations such as secondary beam installation, pull ring welding, lifeline installation, screw driving, and beam end welding are working without safety protection. The main reason for this phenomenon is that the steps for installing the lifeline are too cumbersome and time-consuming, seriously affecting the progress of the hoisting operation project. More importantly, for the U-shaped buckle for rope fixation, it uses a double-mother special tool for pressing, with a small single-body pressure area and prone to loosening and falling off. According to safety regulations, each end of the rope fixation should not be less than three. Due to the large number and the limitations of high-altitude operations, it is difficult to complete any simple operation link effectively and quickly, so the lifeline cannot be synchronized with the first-line hoisting. However, the lifeline is not part of the main structure, but it is a safety barrier for protecting operators. After the floor slab is laid, it is also necessary to cut off the pull rings, disassemble the lifeline, and then touch up the paint at the positions where the pull rings are welded. This link, which has nothing to do with the main structure but is essential for operators, consumes a lot of manpower and material resources for each project. Summary of the Invention

[0003] In order to overcome the deficiencies of the above-mentioned prior art, the present invention provides a multi-directional integrated shackle and a one-way wire fixing tensioner of a top-pressure dual-purpose wire pressing clip combination. Thus, it realizes the synchronous arrival of the first-line hoisting and the lifeline, eliminates the steps of pull ring welding, cutting, and touch-up painting, enables the disassembled lifeline to be directly utilized without re-assembly and without damage in the same project, saves the redundant output of manpower and material resources for the project, and enables all operators to be protected in a timely and effective manner.

[0004] To address the deficiencies of the above-mentioned prior art and the construction method, the technical solution adopted by the present invention is as follows: A steel wire rope with a length similar to the perimeter of the column has four corner protection shackles threaded through it, and the two ends of the rope are respectively fixed with top-pressing dual-purpose wire clamps, thus forming a multi-directional integrated shackle. A top-pressing dual-purpose wire clamp connected by a threaded pipe through bolts constitutes a single-directional wire fixing and tensioning device, and they respectively fix the two ends of the lifeline corresponding to the structural span. When the hoisting operation starts, ground crew members fix the multi-directional integrated shackle on the load-bearing column through bolts at the upper part of each layer of steel beam splicing on the column to be pre-hoisted according to the spacing of the lifeline, forming a lifeline hanging base that does not require welding and can be recycled. When hoisting the steel beam, the assembled lifeline is placed longitudinally and hung on the steel beam. After the construction workers complete the splicing of the steel beam, they connect the lifeline to the base and tighten the bolts to complete the installation of the lifeline.

[0005] Compared with the prior art, the beneficial effects of the present invention are as follows: It realizes the synchronous generation of the lifeline and the hoisting operation in one line, enabling subsequent workers to receive effective protection in the first place and minimizing the risks of high-altitude operations. It eliminates the steps of welding, cutting, painting of the shackles and the inconvenience of high-altitude assembly of the lifeline, saving manpower and material resources for the project, and transferring the cumbersome steps that are difficult to operate at high altitudes to the ground, which can be completed safely and efficiently. At the same time, it also changes the single use of the wire clamp, thus realizing the dual use of one clamp. Description of the Drawings

[0009] The present invention will be further described below with reference to the drawings. (In order to understand this component intuitively and quickly, the structure of this component is depicted using schematic plan and cross-sectional views. Therefore, Figure 1 The numerical serial numbers annotated in abc are all the same parts of the top-pressing dual-purpose wire clamp). As Figure 1The fixed-pressure dual-purpose wire clamp shown in the figure is composed of a device main body 1, a U-shaped straight-through rope passage 2, a rope-preventing stop column 3, an anti-injury rope pressure block 4, a positioning pressure block pin straight-through hole 5, a pressure block slide 6, a pressure block positioning pin 7, a fixed threaded seat 8, a top pressure bolt 9, a connecting ear seat 10, and a bolt straight-through hole 11. In order to prevent the rope from falling off and being pulled out, an anti-rope-falling stop column 3 is provided at one end of the U-shaped straight-through opening. It is located in the middle of the folded rope and is integrated with the device main body. In specific applications, the wire rope passes through the U-shaped straight-through rope passage 2, bypasses the rope-preventing stop column 3, returns and is pulled out from under the anti-injury rope pressure block 4, and then the top pressure bolt 9 is tightened to push the pressure block 4 to fix the rope. In order to reduce the friction resistance and mutual damage when the bolt is pushed, the top pressure bolt 9 is of a cone tail type. In order to ensure that the rope is not damaged, the edge of the U-shaped straight rope passage 2 and the edge of the contact line of the pressure block 4 are both obtuse. The pin 7 is inserted from the pressure block slide 6 through the pin hole 5 and penetrates from the opposite side to lock to prevent the slider from being lost. Among them, the receiving ear seat 10 and the bolt straight hole 11 are used as the receiving end. When the anti-rope falling blocking column 3, the receiving ear seat 10 and the bolt straight hole 11 are deleted, a top pressure type single-use wire clamp is formed. According to different uses, a single-bolt rope clamp and a multi-bolt rope clamp can be realized.

[0010] Figure 2 The multi-directional integrated corner protection ring is shown, which consists of a top-pressing dual-purpose wire clamp 1, a steel wire rope 2, a corner protection ring body 3, and an ear seat 4 with a single bolt hole and an ear seat 5 with an internal thread on the top of the corner protection body 3, which are connected to form a ring through bolts 7. They have a rope threading channel 6, a top-pressing dual-purpose wire clamp 8, a cylindrical hexagonal bolt 9, a twisting straight-through hole 10, and a nut 11. During the assembly process, four corner protection rings 3 are inserted into the middle of the steel wire rope 2, and the top-pressing dual-purpose wire clamps 1 and 8 fix the two ends of the steel wire rope respectively. The outer corner of the corner protection ring body 3 is rounded to protect the steel wire rope from being hurt. The cylindrical bolt 9 adopts a cylindrical hexagonal head, and the twisting straight-through hole 10 is provided on it. The purpose is to use a rod-shaped object for operation when there is no special tool. In specific applications, the assembled multi-directional integrated unloading ring is pulled to the position of the lifeline on the pre-installed load-bearing column, and the cylindrical hexagonal bolts 9 are passed through the top-pressure dual-purpose wire clamps 1 and 8, and the bolt straight-through holes on the receiving ear seat 10 are tightened and fixed with nuts 11, forming a lifeline hanging mother seat that does not require welding and can be recycled.

[0011] Figure 3The one-way wire tensioner is shown, which is composed of a top-pressing dual-purpose wire clamp 1, a cylindrical hexagonal bolt body 2, a twisting straight-through hole 3, an internal threaded pipe seat body 4, a bolt tail telescopic hole 5, and a receiving bolt straight-through hole 6. During the assembly process, the cylindrical bolt body 2 passes through the bolt straight-through hole on the receiving ear seat 10 of the top-pressing dual-purpose wire clamp 1, is screwed into the internal threaded pipe body 4 and retains the tensioning margin, forming a one-way wire tensioner. Use the two dual-purpose wire clamps on the two wire tensioners to fix the two ends of the lifeline respectively, and put it on the beam when the steel beam is hoisted. After the operator has spliced ​​the steel beam, insert the receiving bolt straight-through hole 6 of the tensioner, and tighten and lock it between any 4 and 5 of the corner unloading ring 3 on the mother seat with the bolt 7, and tighten the cylindrical hexagonal bolt body 2 on the one-way tensioner to tighten it, and the lifeline can be quickly pulled and set. Thus, the lifeline and the first-line hoisting are generated synchronously, so that the subsequent operators can get effective protection at the first time and minimize the risk of high-altitude operations. The inconvenient steps of pull ring welding, cutting, repainting and high-altitude assembly of the lifeline are eliminated, which saves manpower and material resources for the project, and transfers the cumbersome steps that are difficult to operate at high altitude to the ground, so that they can be completed safely and efficiently. At the same time, it also changes the single purpose of the rope clamp, thus realizing dual-purpose of one clamp.

[0012] The application of the present invention is not limited to the single field of steel structure, and all applications involving rope clamping, connection and fixation fall within the protection scope of the present invention.
