Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for steel structure construction, and in particular to a prefabricated steel structure safety rope pole that is easy to disassemble and is suitable for safety protection during high-altitude operations. Background Technology

[0002] During the construction of steel structure buildings, the safety protection of workers at heights is paramount, and the installation of safety ropes is one of the key protective measures. Currently, the common practice is to weld safety rope poles onto the steel beams on-site. However, this method has several drawbacks:

[0003] First, the installation of poles usually requires the assistance of hoisting equipment, which increases construction costs and complexity.

[0004] Secondly, welding operations can damage the anti-corrosion layer on the surface of the steel beam, affecting the structural durability, and may even cause the components to deform due to thermal stress.

[0005] Finally, after construction is completed, removing the poles requires cutting operations, which not only involves a large workload and poses safety risks, but also wastes materials and makes them unusable.

[0006] Therefore, there is an urgent need for a prefabricated safety rope pole that requires no welding, can be quickly assembled and disassembled, and can be reused to solve the above-mentioned technical problems. Utility Model Content

[0007] In order to overcome the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide an easy-to-disassemble prefabricated steel structure safety rope pole, which effectively solves the problems of cumbersome installation, difficult dismantling, high cost, damage to the parent material and inability to be recycled of traditional welded safety rope poles.

[0008] To achieve the above objectives, this utility model provides a prefabricated steel structure safety rope pole that is easy to disassemble, comprising: a lower module, detachably fixed to a steel beam by a clamp assembly; an inner insert, fixedly disposed on the lower module; a locking core, disposed on the inner insert, the locking core including a housing, two buckles symmetrically arranged and radially movable within the housing, and an elastic element connected between the two buckles, the elastic element providing an outward preload force to the buckles; an upper module including a pole and an annular pressure ring disposed at the lower end of the pole; wherein, the upper module is connected to the locking core via the annular pressure ring; when connected, the annular pressure ring squeezes the buckles to retract inward until the buckles spring into the locking position of the annular pressure ring under the action of the elastic element, engaging with the annular pressure ring to achieve quick connection; during disassembly, pressing the buckles inward releases the engagement and separates the upper module.

[0009] Preferably, the clamping assembly includes a U-shaped clamp and a locking bolt. The U-shaped clamp is engaged with the flange of the steel beam and locked in place by the locking bolt. The support column of the lower module is fixedly connected to the top of the U-shaped clamp.

[0010] Furthermore, the inner insert includes a tube and a base fixed to the top of the tube. The tube is fixedly sleeved inside the support column, and the base is used to support the locking insert.

[0011] Preferably, the housing of the locking insert is a round tube with a through hole in its wall for the buckle to move; the locking insert also includes a limiting plate for limiting the axial displacement of the buckle.

[0012] Furthermore, the inner hole of the annular pressure ring in the axial direction is machined with a guide slope, and the inclination angle of the guide slope is less than or equal to 8.5°.

[0013] Furthermore, the top outer end of the buckle is a smooth, arc-shaped surface.

[0014] Preferably, the upper module further includes a plurality of safety rope connecting ear plates symmetrically arranged at the upper end of the pole.

[0015] In summary, compared with the prior art, the easily disassembled prefabricated steel structure safety rope pole of this utility model has at least the following beneficial effects:

[0016] 1. Modular design and quick assembly / disassembly: Through the cooperation of the lower module, locking insert and upper module, the safety rope pole can be quickly connected and disassembled by pressing, without welding and cutting, which greatly improves the efficiency of installation and disassembly and reduces labor costs and labor intensity.

[0017] 2. Protection of the base material: The lower module is fixed to the steel beam by clamping components (such as U-clamps and locking bolts), which completely avoids damage to the steel beam base material by welding operations and maintains the integrity of the structure and its corrosion resistance.

[0018] 3. Reusable, energy-saving and environmentally friendly: The entire device can be completely disassembled and reused in different projects, which greatly reduces steel consumption and construction waste, and meets the requirements of green construction.

[0019] 4. Reliable connection: The buckle connection mechanism, designed based on the self-locking principle, ensures the firmness and safety of the connection when subjected to the tension of the safety rope, avoiding the risk of accidental disconnection.

[0020] 5. Transport and installation can be done manually: The size and weight of each module are moderate, and they can be disassembled and carried manually to the work site for assembly, eliminating the need for hoisting equipment and making them more versatile.

[0021] 6. This utility model achieves one-click quick assembly through the cooperation of the annular pressure ring at the lower end of the upper module and the locking insert on the lower module. During installation, a simple press is all that is needed to automatically lock it in place, and during disassembly, simply pressing the buckle allows for easy separation. The entire process requires no welding, cutting, or large hoisting equipment.

[0022] 7. The modular design makes the size and weight of each component suitable for manual handling and operation, significantly saving machinery costs and transportation time; the non-destructive installation method completely avoids damage to the steel beam base material; it can be reused, significantly reducing overall costs and meeting green construction requirements. This utility model is particularly suitable for safety protection in the construction of various steel structure buildings, and has high promotional value and market prospects.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] See below. Figures 1-6 This invention provides a detailed description of the easily disassembled, prefabricated steel structure safety rope pole of this utility model.

[0033] The easily disassembled prefabricated steel structure safety rope pole of this utility model is mainly composed of four modules: lower module 1, inner plug 2, locking core 3, and upper module 4.

[0034] The lower module 1 is detachably fixed to the steel beam via a clamping assembly, supporting the overall structure. For example... Figure 2 As shown, in this embodiment, the clamp assembly uses a U-shaped clamp 11 and a locking bolt 12. The U-shaped clamp 11 is snapped onto the flange of the steel beam and locked in place by the locking bolt 12. The clamp assembly is fixed by clamping the flange of the steel beam. A support column 13 is welded to the top of the U-shaped clamp 11 and is used to receive and position the locking insert 3. The entire lower structure can be easily fixed to the steel beam by the locking bolt 12.

[0035] like Figure 3 As shown, the inner plug-in 2 is welded together from the insertion tube 21 and the base 22. The insertion tube 21 is inserted into and welded to the inner cavity of the support column 13 of the lower module. The base 22 is a horizontal plate structure and is located on top of the insertion tube 21 to support the locking insert 3.

[0036] like Figure 4 As shown, the locking insert 3 is the core component for quick connection. It includes a cylindrical housing 31, two symmetrically arranged and radially movable latches 33 within the housing 31, and an elastic element 34 connecting the two latches 33. The elastic element 34 provides an outward preload force to the latches 33. The housing 31 has two symmetrical through holes in its wall, and the two latches 33 are respectively accommodated in these holes and can move radially. The limiting plate 32 of the locking insert 3 is fixed to the top of the housing 31 to limit the axial displacement of the latches 33 and prevent them from falling upwards. The elastic element 34, acting as a coil spring, is connected between the inner sides of the two latches 33, providing a continuous outward preload force to the latches 33. The locking insert 3 is welded to the base 22 of the inner insert 2 at its bottom.

[0037] like Figure 5As shown, the upper module 4 includes a pole 41, an annular pressure ring 42, and multiple safety rope connecting ear plates 43. The annular pressure ring 42 is fitted and welded to the bottom end of the pole 41. The inner hole of the annular pressure ring 42 in the axial direction is machined with a guide slope to facilitate the sliding of the buckle 33 into the annular pressure ring 42. In the radial direction, it has limiting holes for two buckles 33 to pass through, forming a locking position to align and lock the annular pressure ring 42 with the locking insert 3. The inclination angle of the guide slope is less than or equal to 8.5°. The top outer end of the buckle 33 is a smooth arc-shaped surface, facilitating smoother sliding of the buckle 33 into the annular pressure ring 42. Four safety rope connecting ear plates 43 are symmetrically welded to the upper end of the pole 41 for attaching safety ropes.

[0038] In this invention, the upper module 4 is connected to the locking insert 3 via an annular pressure ring 42. When connected, the annular pressure ring 42 presses the buckle 33 to retract inward until the buckle 33 springs into the locking position of the annular pressure ring 42 under the action of the elastic element 34, and engages with the annular pressure ring 42 to achieve quick connection. When disassembling, pressing the buckle 33 inward can release the engagement and separate the upper module 4.

[0039] Below, refer to Figures 1 to 6 Based on the above description of structural features, the method of using the easily disassembled prefabricated steel structure safety rope pole of this utility model is briefly described as follows:

[0040] Installation process: First, fix the lower module 1 (including the pre-welded inner plug 2 and locking ferrule 3) to the steel beam using U-shaped clamps 11 and locking bolts 12. Then, lower the upper module 4 vertically, aligning its annular pressure ring 42 with the locking ferrule 3. During the downward pressing process, the guide slope of the annular pressure ring 42 contacts and presses against the arc-shaped head of the buckle 33, forcing the buckle 33 to retract inward against the force of the elastic element 34. When the annular pressure ring 42 passes the maximum stroke point of the buckle 33, the buckle 33 quickly pops outward under the pre-tightening force of the elastic element 34, locking into the locking position of the annular pressure ring 42, completing the self-locking connection. At this time, the upper module 4 is firmly locked.

[0041] Disassembly process: When disassembly is required, the construction personnel only need to press the buckles 33 on both sides inward at the same time to disengage them from the annular pressure ring 42, and then lift the upper module 4 upward as a whole to achieve quick and non-destructive disassembly.

[0042] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any transformations or substitutions that can be understood by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of this utility model.
