Description

Technical Field

[0001] This utility model relates to the field of steel structure construction technology, specifically a safety construction device for high-altitude steel structures. Background Technology

[0002] During the construction of high-altitude steel structures, construction workers need to perform installation and welding operations on steel beams and other steel structural components. Due to the high height of the work location, the large spatial span, and the fact that the surface of the steel beams usually lacks fixed protective facilities, the safety protection of construction workers becomes a critical issue.

[0003] A search revealed that a Chinese patent (application number: CN202322186524.1) is a steel structure construction safety belt fastening device. Depending on the construction location, by loosening the nut, the entire fastening device can move left and right along the length of the lower wing plate, making it easy to use. The bottom clamping plate and the upper pressure plate are bolted together and rigidly connected to the steel structure beam, preventing sagging and forming a stable connection. Both the hanging ring and the safety belt hook are ring-shaped, making the connection less prone to wear. The fastening device is reusable, easy to operate, and has high safety performance.

[0004] However, the above-mentioned device has significant drawbacks: the hanging ring is fixed in position and cannot be flexibly adjusted along the length of the steel beam. In actual construction, construction workers need to move along the length of the steel beam. When using the fixed hanging ring, construction workers need to disassemble the entire device and reinstall it in the new position every time they move a certain distance. This is cumbersome and reduces construction efficiency. Moreover, during the disassembly and assembly of the hanging frame, construction workers may be in a state without safety protection, which poses a safety hazard. Therefore, it is necessary to improve the above-mentioned existing technology. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a safety construction device for high-altitude steel structures, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A safety construction device for high-altitude steel structures includes a bottom clamping plate, with upper pressure plates hinged to both sides of the top of the bottom clamping plate. A threaded rod is welded to the side of the upper pressure plate opposite to the bottom clamping plate. A through hole corresponding to the threaded rod is opened on the bottom clamping plate. A nut that mates with the threaded rod is provided below the bottom clamping plate. An installation rod is fixed to the bottom of the bottom clamping plate. The installation rod is set along the length of the steel beam structure. A main hanging ring that can adjust the position is installed at the bottom of the installation rod.

[0007] To achieve position adjustment of the main hanging ring, a sliding groove is provided inside the mounting rod along its length. The sliding groove has a T-shaped cross-section and extends to the bottom of the mounting rod. A sliding plate is provided inside the sliding groove, and the sliding plate slides in conjunction with the upper part of the sliding groove. The main hanging ring is rotatably mounted on the sliding plate, and locking structures are provided on both sides of the sliding plate.

[0008] In order to enable the main hanging ring to rotate, a gap is left between the top of the slide plate and the top of the slide groove, and a rotating plate is provided within the gap. A through circular hole is opened downward at the center of the top of the slide plate, and a vertical circular shaft is fixed at the center of the bottom of the rotating plate. The circular shaft extends out from below the circular hole and is fixed to the top of the main hanging ring.

[0009] To lock the main hanging ring, the locking structure includes two symmetrically arranged extension plates. The extension plates are arranged along the length of the mounting rod and one end is fixed to the slide plate. A threaded hole is opened downward near the top of the free end of the extension plate. Several equally spaced threaded grooves are opened at the top of the slide groove along its length. A threaded post is threadedly connected inside the threaded hole, and the upper end of the threaded post is threadedly installed in the threaded groove.

[0010] Compared with the prior art, this utility model has the following advantages: by setting a sliding plate and a matching locking structure inside the mounting rod, the main hanging ring can be flexibly adjusted along the length of the steel beam, thus improving efficiency. The main hanging ring and the auxiliary hanging ring form a double safety protection. Even if the main hanging ring breaks due to accident, the auxiliary hanging ring can immediately bear the weight of the construction personnel, ensuring their safety. Attached Figure Description

[0013] The following will refer to the appendix in the embodiments of this utility model. Figure 1-5 The technical solutions in the embodiments of this utility model will be clearly and completely described. Example

[0014] A safety construction device for high-altitude steel structures includes a base plate 1 made of Q235 low-carbon steel. Upper pressure plates 2, also made of Q235 low-carbon steel, are hinged to both sides of the top of the base plate 1. A threaded rod 3, made of 45# steel, is welded to the side of the upper pressure plate 2 opposite to the base plate 1. A through hole corresponding to the threaded rod 3 is provided on the base plate 1. A nut 4, an M16 hexagonal nut made of 304 stainless steel, is provided below the base plate 1 to mate with the threaded rod 3. An installation rod 5, made of Q3# steel, is fixed to the bottom of the base plate 1. Made of 45B high-strength steel with a rectangular cross-section, the mounting rod 5 is set along the length of the steel beam structure. An adjustable main hanging ring 6 is installed at the bottom of the mounting rod 5. The main hanging ring 6 is made of 20CrMnTi alloy structural steel. To achieve position adjustment of the main hanging ring 6, a sliding groove 5-1 is formed inside the mounting rod 5 along its length. The sliding groove 5-1 has a T-shaped cross-section, and its bottom extends to the bottom of the mounting rod 5. A sliding plate 7 is installed inside the sliding groove 5-1, slidingly engaging with the upper part of the sliding groove 5-1. The main hanging ring 6 is rotatably mounted on the sliding plate 7, and locking structures are provided on both sides of the sliding plate 7. Before construction, attach the bottom clamp plate 1 to the lower surface of the steel beam, flip the upper pressure plate 2 to the upper surface of the steel beam, pass the threaded rod 3 through the through hole of the bottom clamp plate 1, and tighten the nut 4 to clamp the steel beam. According to the working position, loosen the locking structure and push the slide plate 7 to slide along the slide groove 5-1 so that the main hanging ring 6 reaches the target position and locks. The construction personnel hang the safety rope hook on the main hanging ring 6. When working along the steel beam, the position of the slide plate 7 can be adjusted to make the main hanging ring 6 move with the person, without the need for repeated disassembly and assembly of the device, thus improving efficiency. Example

[0015] Based on the first embodiment, in order to enable the rotation of the main hanging ring 6, a gap is left between the top of the slide plate 7 and the top of the slide groove 5-1, and a rotating plate 8 is provided within the gap. The rotating plate 8 is made of wear-resistant cast iron and is circular. The upper surface of the rotating plate 8 is in contact with the top of the slide groove 5-1, and the lower surface is in contact with the top of the slide plate 7. A through circular hole is opened downward at the center of the top of the slide plate 7. A vertical circular shaft 9 is fixed at the center of the bottom of the rotating plate 8. The circular shaft 9 is made of 40Cr alloy structural steel. The circular shaft 9 rotates out from below the circular hole and is fixed to the top of the main hanging ring 6.

[0016] When construction workers are working, the safety rope pulls the main hanging ring 6, which causes the round shaft 9 to rotate around the round hole of the slide plate 7. At the same time, the rotating plate 8 slides between the slide plate 7 and the top of the slide groove 5-1, so that the main hanging ring 6 can rotate without jamming. This adapts to the safety rope connection needs of construction workers at different working angles such as bending over and turning around, avoids the pulling force of the safety rope due to the fixed angle, and improves the comfort and safety of the operation. Example

[0017] Based on the second embodiment, in order to lock the main hanging ring 6, the locking structure includes two symmetrically arranged extension plates 10. The extension plates 10 are made of Q345B steel. The extension plates 10 are arranged along the length of the mounting rod 5 and one end is fixed to the sliding plate 7. The extension plates 10 have a threaded hole at the top near their free end. Several equally spaced threaded grooves are opened at the top of the slide groove 5-1 along its length. A threaded post 11 is threadedly connected in the threaded hole. The threaded post 11 is made of 304 stainless steel and the upper end of the threaded post 11 is threaded in the threaded groove.

[0018] When adjusting the position of the main hanging ring 6, unscrew the threaded post 11 counterclockwise to disengage it from the threaded groove at the top of the slide 5-1. After pushing the slide plate 7 to the target position, screw the threaded post 11 clockwise until its upper end is fully screwed into the corresponding threaded groove, thereby locking and fixing the slide plate 7 and the main hanging ring 6. In the locked state, the threaded post 11 bears axial tension, preventing the slide plate 7 from accidentally sliding due to the construction personnel pulling the safety rope, ensuring the stability of the position of the main hanging ring 6, and solving the problem of easy displacement of the main hanging ring 6 after adjustment. Example

[0019] Based on the third embodiment, in order to further ensure the safety of construction personnel, a secondary hanging ring 12 is fixed to the lower end of the threaded column 11 extending out of the slide groove 5-1. During construction, the construction personnel hang the two hooks of the safety rope on the main hanging ring 6 and the secondary hanging ring 12 respectively, forming a double safety protection. When the main hanging ring 6 fails due to an accident, such as breaking, the secondary hanging ring 12 can immediately bear the weight of the construction personnel to avoid falling from a height. At the same time, when adjusting the position of the main hanging ring 6, the secondary hanging ring 12 moves synchronously with the threaded column 11 and the slide plate 7, always maintaining a cooperative protective state with the main hanging ring 6. Example

[0020] Based on the fourth embodiment, in order to realize the disassembly and assembly of the main hanging ring 6 and the auxiliary hanging ring 12, the bottom of both ends of the slide groove 5-1 is provided with a long strip-shaped notch 13 for the sliding plate 7 and the two extension plates 10 to slide out. When it is necessary to replace the main hanging ring 6, the auxiliary hanging ring 12 or maintain the sliding plate 7, first unscrew the threaded post 11, push the sliding plate 7 along the length of the slide groove 5-1 toward the notch 13, so that the sliding plate 7 and the extension plates 10 slide out from the notch 13, and the relevant parts can be disassembled. During installation, slide the sliding plate 7 and the extension plates 10 into the slide groove 5-1 from the notch 13, push them to the target position and screw in the threaded post 11 to lock them. The design of the notch 13 makes it convenient to disassemble and assemble the parts without disassembling the entire device.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
