Description

Technical Field

[0001] This application relates to the field of steel structure safety protection technology, and in particular to an adjustable steel structure safety clip. Background Technology

[0002] In the field of steel structure construction, ensuring the safety of construction workers is of paramount importance. With the rapid development of the construction industry, steel structures, due to their high strength, lightweight, and ease of construction, are widely used in various engineering projects. Especially when working on I-beams, their unique flange structure provides a foundation for the installation of safety protection devices. Traditional methods typically rely on installing lifelines on the main or secondary beams, with workers securing themselves by attaching safety hooks to these lifelines. While this measure can reduce risk to some extent, its application and flexibility are subject to many limitations.

[0003] To address the aforementioned issues, the industry commonly employs the following methods: First, a lifeline system is directly installed on the main or secondary beams, with the lifeline connected via fixed anchor points for workers to attach their safety ropes. Second, a clamp-type structure is used to encircle and fix the protective device to the outside of the I-beam, thereby protecting workers. Additionally, some solutions involve designing specific slots or grooves on the I-beam flanges, combined with specialized tools for fixation.

[0004] However, in the existing technology, whether using a lifeline system or a clamp to connect the safety rope, the installation method is relatively fixed and lacks flexibility. This makes it inconvenient for the safety rope to move with the personnel or to adjust the installation position according to the actual situation. As a result, the safety rope needs to be frequently disassembled and installed during construction, which leads to low installation efficiency and is something that needs to be improved. Utility Model Content

[0005] To address the lack of flexibility in traditional safety rope installation methods, this application provides an adjustable steel structure safety clip.

[0006] This application provides an adjustable steel structure safety clip, which adopts the following technical solution:

[0007] An adjustable steel structure safety clamp includes a first clamping plate and a second clamping plate. A positioning component is provided between the first clamping plate and the second clamping plate, and the first clamping plate and the second clamping plate are detachably fixedly connected along the width direction of the I-beam flange by the positioning component. Both the first clamping plate and the second clamping plate are provided with a snap-fit ​​portion, and the snap-fit ​​portion is provided with a snap-fit ​​groove that forms an embedded sliding fit with the I-beam flange. The first clamping plate is provided with a hook portion, and the hook portion is detachably connected to a safety rope.

[0008] By adopting the above technical solution, the first and second clamping plates are detachably fixedly connected along the width direction of the I-beam wing plate through the positioning component, thereby providing stable support for the entire device and allowing for flexible disassembly. The clamping groove on the clamping part forms an embedded sliding fit with the I-beam wing plate, allowing the safety clamp to slide smoothly along the length direction of the I-beam wing plate, thereby flexibly following the position of the operator and improving construction safety and efficiency. At the same time, the hook part is convenient for detachable connection with the safety rope, providing reliable protection for the operator.

[0009] Preferably, the positioning component includes a positioning bolt and a positioning nut, and both the first and second plates are provided with positioning holes. The positioning bolt passes through the positioning holes on the first and second plates and is threadedly connected to the positioning nut.

[0010] By adopting the above technical solution, the first and second clamping plates are detachably fixedly connected by positioning bolts and positioning nuts. This connection method is relatively simple to operate, simplifies the installation steps of the safety clamps and improves the installation efficiency. At the same time, the design of the positioning holes further improves the stability of the connection, ensuring that the first and second clamping plates can be accurately aligned during the installation process, thereby improving the reliability and safety of the overall structure.

[0011] Preferably, multiple positioning holes are provided along the width direction of the I-beam flange.

[0012] By adopting the above technical solution, multiple positioning holes are provided on the first and second clamping plates along the width of the I-beam flange, so that the positioning bolts can be fixed in different positions, thereby realizing the flexible adjustment of the safety clamp on the I-beam flange. This design can not only adapt to I-beams of different sizes, but also improve the convenience of installation and the scope of application.

[0013] Preferably, the inner side of the first card plate is uniformly provided with reinforcing ribs along the width direction of the I-beam flange, and the outer side of the second card plate is uniformly provided with reinforcing ribs along the width direction of the I-beam flange.

[0014] By adopting the above technical solution, reinforcing ribs are uniformly arranged along the width direction of the I-beam flange on both the inner side of the first clamping plate and the outer side of the second clamping plate, which effectively improves the structural strength of the first and second clamping plates without affecting the stability of the fixed connection between the first and second clamping plates. This enhances the stability and reliability of the safety clamp during use. This design can prevent the safety clamp from deforming under stress and ensure a stable connection between it and the I-beam flange, thereby improving the stability of the safety rope installation and reducing the safety risks to workers.

[0015] Preferably, the hook portion includes a clamp fixedly connected to the first plate along the width direction of the first plate and a hook fixedly connected to the clamp, wherein the hook forms a detachable connection with the safety rope.

[0016] By adopting the above technical solution, the clamp is fixedly connected around the width of the first clamp plate, ensuring a firm connection between the hook and the first clamp plate, thereby improving the stability of the overall structure. The hook and the safety rope form a detachable connection, making the installation and removal of the safety rope more convenient, improving construction efficiency, and ensuring the safety of the workers.

[0017] Preferably, a reinforcing rod is provided at the connection between the hook and the clamp, with one end of the reinforcing rod being fixedly connected to the hook and the other end being fixedly connected to the clamp.

[0018] By adopting the above technical solution, the reinforcement rod can enhance the connection strength between the hook and the clamp, effectively preventing the connection from loosening or breaking due to uneven force or external impact during use, thereby improving the stability and reliability of the overall structure and enabling the safety clamp to better protect the safety of workers in practical applications.

[0019] Preferably, the snap-fit ​​portion is provided with an abutment plate, and the abutment plate includes a limiting portion and an abutment portion. The limiting portion is provided with a limiting bolt, and the limiting bolt is threadedly connected to a limiting nut. Both the limiting portion and the snap-fit ​​portion are provided with limiting holes. The limiting bolt passes through the limiting holes on the limiting portion and the snap-fit ​​portion and is threadedly connected to the limiting nut. The abutment portion forms a clearance fit with the inner side of the I-beam.

[0020] By adopting the above technical solution, the setting of the abutment plate enhances the connection stability between the locking part and the I-beam, effectively preventing the safety clamp from loosening or falling off during use. The limiting part uses the cooperation of the limiting bolt and the limiting nut to firmly connect the locking part and the abutment plate. After the abutment plate is installed, its abutment part can form a clearance fit with the inner side of the I-beam. When the locking part is deformed under force, the abutment part can follow the deformation of the locking part to form an abutment fit with the inner side of the I-beam, thereby effectively improving the stability of the entire safety clamp and providing safer protection for the workers.

[0021] Preferably, multiple limiting holes are provided along the width direction of the I-beam flange.

[0022] By adopting the above technical solution, multiple limiting holes are provided on the limiting part and the snap-fit ​​part along the width direction of the I-beam flange, so that the limiting bolt can be selected to pass through the appropriate limiting hole according to actual needs and fixed by the limiting nut. This design not only improves the adaptability of the safety clip on the I-beam and can be adapted to I-beam flanges of different sizes, but also enhances the flexibility and convenience of installation, thereby effectively improving construction efficiency.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The first and second clamping plates are detachably fixedly connected along the width of the I-beam flange by positioning bolts and positioning nuts, thus providing stable support for the entire device and allowing for flexible disassembly. The first and second clamping plates are provided with multiple positioning holes along the width of the I-beam flange. During installation, the appropriate positioning hole can be selected according to the actual situation, so that the safety clamp can be adapted to I-beams of different sizes. The snap-fit ​​groove on the snap-fit ​​part forms an embedded sliding fit with the I-beam flange, so that the safety clamp can slide with the position of the operator, improving construction safety and efficiency and providing reliable protection for the operator.

[0025] 2. The hook part consists of a clamp fixedly connected to the first clamping plate and a hook fixedly connected to the clamp, ensuring the stability of the connection between the hook part and the first clamping plate. The reinforcing rod enhances the connection strength between the hook and the clamp, effectively preventing the connection from loosening or breaking due to uneven force or external impact during use. The abutment plate enhances the connection stability between the clamping part and the I-beam, effectively preventing the safety clips from loosening or falling off during use. Multiple limiting holes are provided on the limiting part and the clamping part along the width direction of the I-beam flange, allowing the abutment plate to adapt to I-beam flanges of different sizes, enhancing the flexibility and convenience of installation.

[0032] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail.

[0033] Embodiment 1 of this application discloses an adjustable steel structure safety clip.

[0034] Reference Figure 1 and Figure 2 An adjustable steel structure safety clamp includes a first clamping plate 1 and a second clamping plate 2 overlapping the outside of the first clamping plate 1. A positioning component 3 is provided between the first clamping plate 1 and the second clamping plate 2, and the first clamping plate 1 and the second clamping plate 2 are detachably fixedly connected along the width direction of the H-beam flange by the positioning component 3. Each of the first clamping plate 1 and the second clamping plate 2 is provided with an "L"-shaped clamping part 5 near the end of the H-beam flange. The clamping part 5 is provided with a clamping groove 51 that forms an embedded sliding fit with the H-beam flange. The first clamping plate 1 is provided with a hook part 6. In this embodiment, the hook part 6 includes a closed semi-circular hook 61. The hook 61 is fixedly connected to the first clamping plate 1 by welding and is detachably connected to the safety rope.

[0035] In actual use, the second clamping plate 2 overlaps the outside of the first clamping plate 1, and the first clamping plate 1 and the second clamping plate 2 are detachably fixedly connected along the width direction of the I-beam wing plate by the positioning component 3, so that the safety clamp can be flexibly disassembled. In addition, the first clamping plate 1 will be subjected to the resistance from the second clamping plate 2 during use, thereby ensuring the stable support of the entire structure. The clamping groove 51 on the clamping part 5 forms an embedded sliding fit with the I-beam wing plate, so that the safety clamp can move with the position of the operator. The hook 61 is welded to the first clamping plate 1 and forms a detachable connection with the safety rope, providing reliable protection for the operator.

[0036] Reference Figure 1 and Figure 2The positioning component 3 includes a positioning bolt 31 and a positioning nut 32 threaded onto the positioning bolt 31. In this embodiment, two positioning bolts 31 and two positioning nuts 32 are provided. Multiple equally spaced positioning holes 4 are provided on the first clamping plate 1 and the second clamping plate 2 along the width direction of the I-beam flange. In this embodiment, five positioning holes 4 are provided. Any one of the positioning bolts 31 passes through the positioning holes 4 on the first clamping plate 1 and the second clamping plate 2 and is threaded onto the positioning nut 32. In actual use, the first clamping plate 1 and the second clamping plate 2 form a detachable fixed connection along the width direction of the I-beam flange through the positioning bolts 31 and the positioning nuts 32. This connection method simplifies the installation steps of the safety clamp and improves the installation efficiency. Multiple positioning holes 4 are provided on the first clamping plate 1 and the second clamping plate 2. During installation, the appropriate positioning hole 4 can be selected according to the actual situation, so that the safety clamp can be adapted to I-beams of different sizes.

[0037] Reference Figure 3 In other embodiments, reinforcing ribs 7 can be uniformly arranged along the width direction of the I-beam flange on the inner side of the first clamping plate 1, and reinforcing ribs 7 can be uniformly arranged along the width direction of the I-beam flange on the outer side of the second clamping plate 2. In actual use, the reinforcing ribs 7 are uniformly arranged along the width direction of the I-beam flange on both the inner side of the first clamping plate 1 and the outer side of the second clamping plate 2, which can prevent the safety clamp from deforming under stress and will not affect the stability of the connection between the first clamping plate 1 and the second clamping plate 2, thereby ensuring a stable connection between it and the I-beam flange.

[0038] The implementation principle of Embodiment 1 of this application is as follows: The first clamping plate 1 and the second clamping plate 2 are detachably fixedly connected along the width direction of the I-beam flange by positioning bolts 31 and positioning nuts 32, thereby providing stable support for the entire device and allowing for flexible disassembly. The five equidistant positioning holes 4 on the first clamping plate 1 and the second clamping plate 2 realize the adjustment of the spacing between the safety clamps, so that the safety clamps can be adapted to I-beam flanges of different sizes. The clamping groove 51 on the clamping part 5 forms an embedded sliding fit with the I-beam flange, so that the safety clamps can move with the workers. The hook 61 on the first clamping plate 1, which is in the shape of a closed semi-circular ring, is welded to ensure strength and, together with the detachable safety rope, provides fall protection for the workers. In other embodiments, the reinforcing ribs 7 are evenly distributed along the width direction of the I-beam flange on the inner side of the first clamping plate 1 and the outer side of the second clamping plate 2, effectively suppressing the deformation of the safety clamps under stress and maintaining the fitting stability of the clamping groove 51 and the I-beam, thereby achieving dual protection of safety and structural rigidity in dynamic construction.

[0039] This application also discloses an adjustable steel structure safety clip in embodiment two, which differs from embodiment one in that:

[0040] Reference Figure 4 and Figure 5The hook part 6 includes a clamp 62 fixedly connected to the first clamp 1 along the width direction of the first clamp 1, and a hook 61 fixedly connected to the clamp 62. In this embodiment, the clamp 62 and the first clamp 1, as well as the hook 61 and the clamp 62, are fixedly connected by welding. The hook 61 is detachably connected to the safety rope. Both ends of the hook 61 and the clamp 62 are provided with reinforcing rods 63. In this embodiment, two reinforcing rods 63 are provided at either end of the hook 61 and the clamp 62, and the two reinforcing rods 63 are symmetrically arranged about the hook 61. The two ends of any reinforcing rod 63 are respectively welded to the hook 61 and the clamp 62. In actual use, the clamp 62 is welded to the first clamp 1 and the hook 61 is welded to the clamp 62, ensuring a firm connection between the hook part 6 and the first clamp 1. The two reinforcing rods 63 welded to either end of the hook 61 and the clamp 62 can enhance the connection strength between the hook 61 and the clamp 62 and improve the stability and reliability of the overall structure.

[0041] Reference Figure 5 The snap-fit ​​part 5 is provided with an abutment plate 8 at one end near the inner side of the I-beam. The abutment plate 8 includes a limiting part 81 and an abutment part 82, with the limiting part 81 perpendicular to the abutment part 82. A limiting bolt 52 is provided on the limiting part 81, and a limiting nut 53 is threadedly connected to the limiting bolt 52. Both the limiting part 81 and the snap-fit ​​part 5 at one end near the inner side of the I-beam are provided with a plurality of equally spaced limiting holes 9 along the width direction of the I-beam flange. In this embodiment, four limiting holes 9 are provided. The limiting bolt 52 passes through the limiting holes 9 on the limiting part 81 and the snap-fit ​​part 5 and is threadedly connected to the limiting nut 53. At this time, the abutment part 82 forms a clearance fit with the inner side of the I-beam.

[0042] In practical use, the limiting part 81 on the abutment plate 8 is detachably fixedly connected to the end of the snap-fit ​​part 5 near the inner side of the I-beam through the limiting bolt 52 and the limiting nut 53, and the abutment part 82 forms a clearance fit with the inner side of the I-beam. When the snap-fit ​​part 5 is deformed under force, the abutment part 82 can follow the deformation of the snap-fit ​​part 5 and form an abutment fit with the inner side of the I-beam to prevent the safety clip from loosening or falling off during use. The limiting part 81 and the end of the snap-fit ​​part 5 near the inner side of the I-beam are provided with multiple limiting holes 9 along the width direction of the I-beam flange, so the installation position can be flexibly adjusted during installation.

[0043] The implementation principle of Embodiment 2 of this application is as follows: the clamp 62 is welded to the first clamp plate 1 and the hook 61 is welded to the clamp 62. With the symmetrically distributed reinforcing rods 63, the force is dispersed, which significantly enhances the tensile strength between the hook 61 and the first clamp plate 1. This effectively prevents the connection from loosening or breaking due to uneven force or external impact during use. At the same time, the limiting part 81 of the abutment plate 8 and the clamping part 5 form an adjustable rigid support through the limiting bolt 52 and the limiting nut 53 passing through the limiting hole 9. This makes the abutment part 82 of the abutment plate 8 form a clearance fit with the inner side of the I-beam, which enhances the connection stability between the clamping part 5 and the I-beam. This effectively prevents the safety clip from loosening or falling off during use, providing safer protection for the workers. The limiting part 81 and the clamping part 5 near the inner side of the I-beam are provided with multiple limiting holes 9 along the width direction of the I-beam flange. The installation position can be flexibly adjusted during installation, so that the positioning clip can be adapted to I-beams of different sizes.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
