Description
Technical Field
[0001] This utility model relates to the field of fall protection components, and in particular to a fall protection component for the roof of a steel structure building. Background Technology
[0002] Steel-framed buildings are a type of building that uses steel as its primary load-bearing structure. Through the connection and assembly of steel components, a skeletal system is formed, which, together with the enclosure structure and other auxiliary facilities, constitutes a complete architectural space. It is characterized by high strength, light weight, and rapid construction.
[0003] During the construction of steel structure buildings, the roof is usually covered with corrugated steel sheets. People stand on the corrugated steel sheets to carry out various operations. However, because the corrugated steel sheets on the top of such buildings are relatively smooth, people are prone to falling during operation, causing safety accidents. Therefore, fall protection components are required.
[0004] In the use of existing steel structure building roof fall protection components, multiple anchors are usually fixed to various parts of the corrugated steel sheet with fastening screws. Then, steel wire ropes are threaded through the cylinders on the multiple anchors, so that the steel wire ropes and multiple anchors form a support network. When working, the safety rope buckle is put on the steel wire rope, and the steel wire rope and safety rope are used to suspend the personnel, thereby achieving fall protection for the personnel.
[0005] However, since the gantry frame is usually welded and fixed to the anchor, and will be placed outdoors for a long time after installation, it may rust after being corroded by external rainwater, which will reduce the strength of the weld. This will make the gantry frame easy to separate from the anchor after being subjected to strong impact, thus affecting the fall protection effect. Summary of the Invention
[0006] The technical problem this utility model aims to solve is that since the tube frame is usually welded and fixed to the anchor seat, and is placed outdoors for a long time after installation, it may rust after being corroded by external rainwater, which reduces the strength of the weld and makes the tube frame easy to separate from the anchor seat after being subjected to strong impact, thus affecting the fall prevention effect.
[0007] The technical solution adopted by this utility model to solve its technical problem is: a steel structure building roof anti-fall component, including: an anchor seat, a cylindrical frame is provided on one side of the anchor seat, and a steel wire rope is inserted inside the cylindrical frame; a protective device is provided on the anchor seat, wherein the protective device is used to initially withstand the impact force and weight brought by the steel wire rope and to provide secondary reinforcement to the steel wire rope.
[0008] Preferably, the protective device includes: a slot, the slot being formed on an anchor seat, wherein a threaded hole is formed on the side of the anchor seat near the slot, and a bolt is threadedly connected to the inner wall of the threaded hole; a hole block, the surface of which is slidably connected to the inner wall of the slot, wherein the hole block is placed inside the slot and fixed by bolts, and a rod is slidably connected to the inner wall of the hole block; and a sleeve plate, the sleeve plate being fixedly connected to the rod, wherein a steel wire rope is inserted inside the sleeve plate.
[0009] The aforementioned components achieve the following effect: By setting up a protective device, the hole block is first manually moved to move the support rod, which in turn moves the sleeve plate. When the hole block is fully inserted into the slot, the inner wall of the hole on the hole block coincides with the inner wall of the threaded hole. At this point, the bolt is manually screwed into the threaded hole and the hole block to fix the hole block in position, completing the assembly and fixation of the sleeve plate and the anchor. Then, the wire rope is sequentially inserted into the drum frame and the sleeve plate. When the wire rope is under tension, the sleeve plate preferentially supports the wire rope. It bears the impact and weight of the wire rope. If the sleeve plate breaks, the force generated by the wire rope is transferred to the drum frame. This allows the drum frame and sleeve plate to provide double stress and protection for the wire rope, thus achieving double-layer protection for the wire rope. This reduces the chance of rust and aging caused by rain and other corrosion when the drum frame is placed outdoors for a long time, which would reduce the strength of the weld and cause the drum frame to separate from the anchor after being subjected to the impact of the wire rope. This further improves the stability of the wire rope and the protection of personnel.
[0010] Preferably, the surface of the bolt is fixed with a plurality of auxiliary blocks, which are arranged at equal intervals.
[0011] The effect achieved by the above components is that by setting up auxiliary blocks, the hands can be assisted in interception, reducing the chance of slipping when manually turning the bolts.
[0012] Preferably, a rubber block is fixed to the side of the rod frame near the hole block, wherein the surface of the rubber block is in contact with the hole block.
[0013] The effect achieved by the above components is as follows: by setting up rubber blocks, when the rod moves under force, it drives the rubber blocks to move closer to the hole blocks, so that the rod compresses the rubber blocks during the movement, causing the rubber blocks to deform and store impact energy by utilizing their own high elastic deformation. By using viscoelasticity, some energy is dissipated through intramolecular friction. At the same time, the deformation prolongs the impact time to reduce the instantaneous impact force. After the external force disappears, the stored energy is slowly released, thereby achieving impact buffering.
[0014] Preferably, a damping rod is fixedly connected to one side of the hole block, wherein the other end of the damping rod is fixedly connected to the sleeve plate.
[0015] The effect achieved by the above components is as follows: by setting up a damping rod, when the sleeve moves under force, the damping rod dissipates the impact energy through the flow resistance of the damping medium or solid friction, thereby buffering the impact force, further reducing the impact force on the sleeve, and increasing the dragging effect on the wire rope.
[0016] Preferably, the surface of the sleeve plate is fixed with multiple reinforcing ribs, wherein the reinforcing ribs are made of nickel alloy.
[0017] The effect achieved by the above components is that the strength of the sleeve plate can be increased by setting reinforcing ribs, reducing the possibility of the sleeve plate breaking or deforming under stress.
[0018] Preferably, a metal ring is fixed to the inner wall of the sleeve, wherein the metal ring is positioned at the edge of the sleeve.
[0019] The effect achieved by the above components is as follows: by setting the metal ring, the metal ring can replace the sleeve plate to contact the surface of the wire rope, reducing the friction and wear between the two, while further reinforcing the edge position of the sleeve plate and increasing its stress strength.
[0020] Preferably, a limiting groove is formed on the inner wall of the slot, and a limiting block is fixed to the surface of the hole block, wherein the limiting block is placed inside the limiting groove to limit the hole block.
[0021] The effect achieved by the above components is as follows: by setting the limiting block and the limiting groove, the limiting block can be placed inside the limiting groove to position the hole block, so that the inner wall of the hole block can quickly correspond to the inner wall of the threaded hole, thereby improving the convenience of installing the hole block.
[0022] The beneficial effects of this utility model are:
[0023] By installing protective devices, the impact and weight of the wire rope can be absorbed first, and the gantry can then bear the load after the wire rope breaks. This achieves double protection and dragging of the wire rope, reducing the risk of rust and aging caused by rain and other corrosion when the gantry is placed outdoors for a long time. This reduces the strength of the welds and prevents the gantry from separating from the anchor after being subjected to the impact of the wire rope. This improves the dragging stability of the wire rope and the protection of personnel. Attached Figure Description

[0030] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0032] Figure 1-4 The steel structure building roof fall protection component shown includes: an anchor 1, a cylindrical frame 2 is provided on one side of the anchor 1, and a steel wire rope 3 is inserted inside the cylindrical frame 2; a protective device 4 is provided on the anchor 1, wherein the protective device 4 is used to initially withstand the impact force and weight brought by the steel wire rope 3 and to provide secondary reinforcement to the steel wire rope 3.
[0033] Figure 2 , Figure 3 and Figure 4The protective device 4 shown includes: a slot 41, which is formed on the anchor 1, wherein the anchor 1 has a threaded hole 42 on the side near the slot 41, and a bolt 44 is threadedly connected to the inner wall of the threaded hole 42; a hole block 46, the surface of which is slidably connected to the inner wall of the slot 41, wherein the hole block 46 is placed inside the slot 41 and fixed by the bolt 44, and a rod 47 is slidably connected to the inner wall of the hole block 46; and a sleeve plate 48, which is fixedly connected to the rod 47, wherein a steel wire rope 3 is inserted inside the sleeve plate 48. By setting the protective device 4, the hole block 46 is first manually moved to move the rod, which in turn moves the sleeve plate 48. When the hole block 46 is moved to the position where it is fully inserted into the slot 41, the inner wall of the hole on the hole block 46 coincides with the inner wall of the threaded hole 42. At this time, the bolt 44 is manually screwed in. The threaded hole 42 and the hole block 46 are used to fix the position of the hole block 46, completing the assembly and fixation of the sleeve plate 48 and the anchor seat 1. At this time, the wire rope 3 is inserted into the cylinder frame 2 and the sleeve plate 48 in sequence. When the wire rope 3 is under force, the sleeve plate 48 will first drag the wire rope 3 and bear the impact force and weight brought by the wire rope 3. If the sleeve plate 48 breaks, the force generated by the wire rope 3 will be transferred to the cylinder frame 2. The cylinder frame 2 and the sleeve plate 48 can provide double force and protection for the wire rope 3, thereby achieving double protection for the wire rope 3. This reduces the possibility of rust and aging caused by rain and other corrosion when the cylinder frame 2 is placed outdoors for a long time, which would reduce the strength of the welding and cause the cylinder frame 2 to separate from the anchor seat 1 after being subjected to the impact force brought by the wire rope 3. This further improves the stability of the dragging of the wire rope 3 and the protection of personnel.
[0034] Figure 2 , Figure 3 and Figure 4 Multiple auxiliary blocks 45 are fixed to the surface of the bolt 44 shown. The auxiliary blocks 45 are arranged at equal intervals. By setting the auxiliary blocks 45, the hand can be assisted to prevent slippage when manually turning the bolt 44. A rubber block 411 is fixed to the side of the rod 47 near the hole block 46. The surface of the rubber block 411 is in contact with the hole block 46. By setting the rubber block 411, when the rod 47 moves under force, it drives the rubber block 411 to move closer to the hole block 46. During the movement, the rod 47 squeezes the rubber block 411, causing the rubber block 411 to deform and store impact energy using its high elastic deformation. Some energy is dissipated through intramolecular friction by means of viscoelasticity. At the same time, the deformation prolongs the impact time to reduce the instantaneous impact force. After the external force disappears, the stored energy is slowly released, thereby achieving impact buffering.
[0035] Figure 2 , Figure 3 and Figure 4A damping rod 413 is fixedly connected to one side of the hole block 46 shown. The other end of the damping rod 413 is fixedly connected to the sleeve plate 48. By setting the damping rod 413, when the sleeve plate 48 moves under force, the damping rod 413 dissipates the impact energy through the flow resistance of the damping medium or solid friction, thereby buffering the impact force and further reducing the impact force on the sleeve plate 48, increasing the dragging effect on the wire rope 3. Multiple reinforcing ribs 49 are fixedly connected to the surface of the sleeve plate 48. The reinforcing ribs 49 are made of nickel alloy. By setting the reinforcing ribs 49, the strength of the sleeve plate 48 can be increased, reducing the possibility of breakage or deformation of the sleeve plate 48 under force.
[0036] Figure 2 , Figure 3 and Figure 4 A metal ring 410 is fixed to the inner wall of the sleeve plate 48 shown. The metal ring 410 is located at the edge of the sleeve plate 48. By setting the metal ring 410, the metal ring 410 can replace the sleeve plate 48 in contact with the surface of the wire rope 3, reducing the friction and wear between the two. At the same time, it further strengthens the edge of the sleeve plate 48 and increases its strength. A limiting groove 43 is opened on the inner wall of the slot 41. A limiting block 412 is fixed to the surface of the hole block 46. The limiting block 412 is placed inside the limiting groove 43 to limit the hole block 46. By setting the limiting block 412 and the limiting groove 43, the limiting block 412 can be placed inside the limiting groove 43 to position the hole block 46, so that the inner wall of the hole block 46 can quickly correspond to the inner wall of the threaded hole 42, improving the convenience of installing the hole block 46.
[0037] Working principle: First, multiple anchors 1 are fixedly installed at various locations on the color steel sheet using mounting brackets and fastening screws. Then, steel wire ropes 3 are threaded into the tube frames 2 on the multiple anchors 1, so that the steel wire ropes 3 and the multiple anchors 1 form a support network, thereby completing the overall installation of the anti-fall component.
[0038] At this time, manually move the hole block 46 to drive the frame rod to move, so that the frame rod drives the sleeve plate 48 to move. When the hole block 46 moves to the position of being fully inserted into the slot 41, the inner wall of the hole on the hole block 46 coincides with the inner wall of the threaded hole 42. At this time, manually screw the bolt 44 into the threaded hole 42 and the hole block 46 to fix the position of the hole block 46, and complete the assembly and fixation of the sleeve plate 48 and the anchor 1. At the same time, the wire rope 3 is inserted into the cylinder frame 2 and the sleeve plate 48 in sequence. When the wire rope 3 is under force, the sleeve plate 48 will first drag the wire rope 3 and bear the impact force and weight brought by the wire rope 3. If the sleeve plate 48 breaks, the force generated by the wire rope 3 will be transferred to the cylinder frame 2, so that the cylinder frame 2 and the sleeve plate 48 can provide double force and protection for the wire rope 3, thereby achieving double protection for the wire rope 3.
[0039] When the rod 47 and the sleeve 48 move under force, they drive the rubber block 411 to move closer to the hole block 46. During the movement, the rod 47 squeezes the rubber block 411, causing the rubber block 411 to deform and store impact energy through its high elastic deformation. It dissipates some energy through intramolecular friction using viscoelasticity. At the same time, the deformation prolongs the impact time to reduce the instantaneous impact force. After the external force disappears, the stored energy is slowly released. Meanwhile, the damping rod 413 dissipates the impact energy through the flow resistance of the damping medium or solid friction, thereby achieving the buffering of the impact force.
[0040] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
