Description

Technical Field

[0001] This utility model relates to the field of safety rope fixing technology, specifically, to a safety rope fixing structure for construction. Background Technology

[0002] Construction refers to the production activities during the implementation phase of a project. It is the process of building various types of structures, or the process of turning the lines on design drawings into a physical object at a designated location. It includes foundation construction, main structure construction, roofing construction, and decoration construction. The site where construction work takes place is called the "construction site" or "building site."

[0003] On construction sites, the roof beams of ordinary steel structure factory buildings are generally I-beams. When workers install roof accessories such as steel purlins, they can only fix the safety rope to the top of the steel column and then fasten the safety belt to the safety rope. Since the roof accessories are all located on the upper part of the steel column, the safety belt cannot be used with a high attachment point, posing a safety hazard. In addition, the safety belt cannot be adjusted in position when it is attached to the safety rope on the steel column, limiting the range of movement. To address this, Chinese Patent Publication No. CN220469447U provides a steel structure safety rope fixing device. By installing two fixed brackets on the top of the I-beam of the steel structure factory building roof to fix the safety rope, and connecting the safety rope with pulls at both ends, the safety belt can be used with a high attachment point, ensuring the safety of construction workers. Moreover, the method of connecting the safety rope with pulls at both ends expands the attachment range of the safety belt.

[0004] In the above technology, the safety rope is connected between the fixed brackets by a pull-out method and the rope threading component is fixed by screws. However, the other side of the rope threading component only has a rope hole. When using it, the staff needs to pass the safety rope through the rope hole and tie a knot to tighten it. If the knot is not tied properly, the safety rope may be not securely fixed and lose its fixing effect. Utility Model Content

[0005] This utility model provides a safety rope fixing structure for construction. It involves two linear sections of rope forming a "U" shape after the safety rope passes through a rope threading device, which then pass through protective clamps. The protective clamps secure the safety rope with bolts and nuts on both sides, and also incorporate anti-slip protrusions to enhance anti-slip resistance, thereby solving the problems mentioned in the background art.

[0006] In existing technology, the safety rope only passes through the rope hole and needs to be knotted and tightened. However, if the worker is negligent, the knotting may be incorrect, resulting in the safety rope being unstable.

[0007] To achieve the above objectives, the safety rope fixing structure for construction includes an I-beam and a fixing mechanism. The fixing mechanism includes an upper fixing plate and a lower fixing plate that are snapped into the I-beam. Inclined plates are symmetrically welded to the inner sides of the upper and lower fixing plates. The inclination angle of the inclined plates is 30° to 45°. A pin is provided between the inclined plates. The pin passes through the guide grooves of the inclined plates on both sides and drives the two fixing plates to clamp the I-beam by axial movement.

[0008] The top of the upper fixing plate is provided with a connecting rod, and the end of the connecting rod is connected to a rope threading component;

[0009] The rope threading device is fitted with a safety rope to form a U-shaped double rope segment, and the two rope segments pass through the rope hole of the protective clamp respectively;

[0010] The protective clamp includes two symmetrically arranged clamping plates, forming a channel between the clamping plates for a U-shaped safety rope to pass through. The anti-slip protrusions on the inner wall of the channel are trapezoidal protrusions.

[0011] The protective clamp is equipped with bolt and nut assemblies on both sides, and its inner wall is provided with anti-slip protrusions that contact the surface of the safety rope.

[0012] In the above technical solution, the safety rope is threaded into a U-shaped double rope segment by the rope threading component, and the two rope segments are guided to pass through the rope hole of the protective clamp in parallel. The radial clamping force is applied by the bolt and nut assembly symmetrically arranged on both sides of the protective clamp, so that the two clamping plates squeeze the U-shaped rope segment inward.

[0013] Meanwhile, the trapezoidal anti-slip protrusions on the inner wall of the clamp channel form multi-point interlocking contact with the surface of the safety rope. The sharp edges of the protrusions embed into the surface fibers of the safety rope, significantly increasing the friction to resist slippage.

[0014] During this process, the tightening force of the bolts is converted into uniform pressure on the rope segment through the clamping plate, while the staggered distribution of the trapezoidal protrusions further enhances the anti-slip effect by utilizing shear force. In addition, the fixing mechanism adopts a lever-type locking structure composed of an inclined plate and a pin. When the pin moves axially along the guide groove of the inclined plate, the inclination angle converts the pin thrust into the clamping force of the upper and lower fixing plates on the flange of the I-shaped steel. The locking effect is amplified through the lever principle, ensuring the stability of the fixing mechanism on the I-shaped steel. Based on this...

[0015] In another technical solution, one end of the pin is provided with a radial through hole, and a limiting pin is inserted into the through hole. The limiting pin is inserted through the radial through hole at one end of the pin to form a physical blocking structure, which effectively prevents the pin from axially displacing due to vibration or external force after clamping the I-beam.

[0016] When the pin moves axially along the guide groove of the inclined plate to the preset position for clamping the I-beam, the limiting pin is vertically inserted into the radial through hole of the pin, and the mechanical interference of the pin body directly blocks the return path of the pin, thereby forcibly fixing the pin in the optimal locking position.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] When the safety rope is clamped by the protective clamps in the U-shaped double rope segment formed by the rope threading device, the trapezoidal anti-slip protrusions and the bolt and nut assembly work together to form a multi-level anti-slip mechanism. The sharp edges of the trapezoidal protrusions embed into the safety rope fiber layer, generating interlocking friction, while the bolt clamping force is converted into uniform radial pressure through symmetrical clamping plates. This dual action significantly improves the anti-slip capability, replacing the traditional knot fixing method and avoiding human error. The overall structure, through rigid mechanical locking and friction enhancement design, achieves zero-backflow fixation of the safety rope under dynamic load, ensuring the safety and reliability of high-altitude operations.

[0027] 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.

[0028] Currently, in existing technologies, the safety rope 101 only passes through the rope hole and needs to be knotted and tightened. However, this can lead to inaccurate knotting due to worker negligence, resulting in the safety rope 101 being unstable. This utility model provides a safety rope fixing structure for construction. (See [link]) Figures 3-5 As shown, it includes an I-beam 100 and a fixing mechanism 200. The fixing mechanism 200 includes an upper fixing plate 202 and a lower fixing plate 201 that are snapped into the I-beam 100. Inclined plates 203 are symmetrically welded to the inner sides of the upper fixing plate 202 and the lower fixing plate 201. The inclination angle of the inclined plates 203 is 30° to 45°. A pin 204 is provided between the inclined plates 203. The pin 204 passes through the guide groove of the inclined plates 203 on both sides and drives the two fixing plates to clamp the I-beam 100 by axial movement.

[0029] The top of the upper fixing plate 202 is provided with a connecting rod 206, and the end of the connecting rod 206 is connected to a rope threading piece 207;

[0030] The end face of the connecting rod (206) is T-shaped, and its end is fixed to the rope threading part (207) through a threaded hole;

[0031] A safety rope 101 is threaded onto the rope threading component 207 to form a U-shaped double rope segment, and the two rope segments pass through the rope hole of the protective clamp 208 respectively;

[0032] The protective clamp 208 has bolt and nut assemblies on both sides, and its inner wall has anti-slip protrusions 209 that contact the surface of the safety rope 101.

[0033] Furthermore, the protective clamp 208 has at least three sets of through threaded holes on its outer side. Bolts pass through the threaded holes and are tightened by nuts, so that the protective clamp 208 applies radial clamping force to the U-shaped safety rope 101.

[0034] Example 1, as Figure 5 As shown, the safety rope 101 passes through the annular end of the rope threading member 207 to form a U-shaped double rope segment. The two rope segments pass parallel through the symmetrical clamping plate channel of the protective clamp 208. The inner walls of the two clamping plates of the protective clamp 208 are provided with trapezoidal anti-slip protrusions 209, with their sharp edges facing the surface of the safety rope 101. Tighten the three sets of bolt and nut assemblies on both sides of the protective clamp 208. The bolt and nut assemblies are symmetrically distributed along the length of the clamping plate. The axial clamping force of the bolts is converted into uniform radial pressure through the clamping plate, forcing the trapezoidal anti-slip protrusions 209 to embed into the surface fibers of the safety rope 101. The inclined surface design of the trapezoidal anti-slip protrusions 209 concentrates the pressure at the tip of the protrusion, forming a multi-point interlocking contact to inhibit rope segment slippage. During this process, the double-strand structure of the U-shaped rope segment forms a self-locking effect in the protective clamp 208, which, together with the bolt tightening and the protrusion interlocking, achieves a double anti-slip mechanism.

[0035] Example 2 Figures 1-4 In the process of fixing the mechanism 200, when it is installed on the flange of the I-beam 100, the upper fixing plate 202 and the lower fixing plate 201 are respectively snapped onto the upper and lower flange surfaces of the I-beam 100. The inclined plates 203, which are symmetrically welded to the inner sides of the two fixing plates, have an inclination angle of 30°~45°. The pin 204 is inserted into the guide groove of the inclined plate 203 in a straight line. The pin 204 is moved along the guide groove by mechanical push. At this time, the inclination angle decomposes the axial thrust of the pin 204 into a horizontal component and a vertical component. The horizontal force drives the upper fixed plate 202 and the lower fixed plate 201 to open to both sides of the flange of the I-shaped steel 100, and the vertical force forces the fixed plate to fit tightly with the flange of the I-shaped steel 100, forming a lever-type clamping. When the pin 204 moves to the preset position, that is, when the clamping force reaches the maximum value, the limit pin 205 is vertically inserted into the radial through hole at the end of the pin 204. The mechanical interference between the limit pin 205 and the side wall of the inclined plate 203 completely locks the pin 204 to prevent it from retracting, ensuring that the clamping force is constant.

[0036] Working principle: In use, the upper fixed plate 202 and the lower fixed plate 201 engage the flange of the I-shaped steel 100. When the pin 204 moves axially along the 30°~45° guide groove of the inclined plate 203, the resulting vertical force forces the upper fixed plate 202 and the lower fixed plate 201 to open outward to bite the flange of the I-shaped steel 100. The vertical force also drives the fixed plate to fit tightly against the I-shaped steel 100, forming a lever-type rigid lock. After the safety rope 101 is threaded through the rope threading piece 207 to form a U-shaped double rope segment, it passes parallel through the clamping plate channel of the protective clamp 208. Tightening the bolt and nut assemblies on both sides causes the tip of the trapezoidal anti-slip protrusion 209 to embed into the fiber layer of the safety rope 101. Through the dual action of protrusion biting friction and radial clamping force, the safety rope 101 is fixed with zero backing. The limiting pin 205 at the end of the pin 204 physically prevents the pin 204 from displacing, ensuring that the clamping force is stable and long-lasting.
