[0002] my country's steel structure industry is developing rapidly, especially in high-rise buildings and large-span spatial structures. However, workers on steel structure construction sites face significant risks when walking or operating on steel beams, with falls being the most serious hazard. Therefore, ensuring worker safety during steel structure construction is an urgent problem to be solved.

[0003] In traditional structural construction, most existing lifeline poles use fixed-size clamps. These mechanical clamps have limitations, such as short adjustment strokes, making them unsuitable for the flange widths of H-beams with different cross-sectional dimensions. Secondly, aging lifeline poles may sometimes exhibit insufficient clamping force or uneven clamping contact, causing pole swaying during high-altitude operations. Furthermore, repeated disassembly and assembly reduces construction efficiency. Additionally, existing lifeline poles occupy a significant amount of space; the capacity required for a single project is often substantial, greatly consuming available site space. This traditional pole installation method fails to effectively address issues of adaptability, safety, and convenience, posing significant safety hazards, especially in high-altitude projects.

[0004] Therefore, there is an urgent need for an adaptive adjustable steel structure lifeline pole device that can adapt to steel beam flanges of various widths and improve versatility, convenience, stability, and safety. Utility Model Content

[0034] Most existing lifeline poles use fixed-size clamps. These mechanical clamps have a short adjustment stroke, making them unsuitable for the flange widths of H-beams with different cross-sectional dimensions. Secondly, aging lifeline poles may sometimes experience insufficient clamping force or uneven clamping contact, causing the pole to sway during high-altitude operations. Furthermore, repeated disassembly and assembly reduces construction efficiency. Additionally, existing lifeline poles occupy a significant amount of space; the capacity required for a single project is often enormous, greatly consuming available site space. This traditional pole installation method fails to effectively address issues of adaptability, safety, and convenience, especially in high-altitude projects, posing significant safety hazards.

[0035] To address the aforementioned problems, this utility model provides an adaptive adjustable steel structure lifeline pole device. The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0036] To illustrate the adaptive adjustable steel structure lifeline pole device provided by this utility model. Figures 1-4 The embodiments of this utility model are illustrated by way of example.

[0037] The following description of exemplary embodiments is merely illustrative and is in no way intended to limit the invention or its application or use. Techniques and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques and equipment should be considered part of the specification.

[0038] like Figures 1-4As shown in the figure, this utility model provides an adaptive adjustable steel structure lifeline pole device, including a first clamp 13 and a second clamp 14 clamped on both sides of the steel beam flange 1; the first clamp 13 and the second clamp 14 can be adjusted and fixed by a threaded adjusting screw 12; wherein, a pole is provided above the first clamp 13 or the second clamp 14; the pole includes a pole body 10 and a pole fixing base 6, and fixing holes are provided on the first clamp 13 and the second clamp 14; A fastening bolt 7 passes through the fixing hole; wherein, if no upright is provided on the first clamp or the second clamp, the fastening bolt 7 passes through the fixing hole to fasten the first clamp 13 or the second clamp 14 to the steel beam flange 1; if an upright is provided on the first clamp 13 or the second clamp 14, the fastening bolt 7 passes through the upright base hole and the fixing hole on the upright fixing base 6 to fasten the first clamp or the second clamp to the steel beam flange, and fixes the upright fixing base 6 above the first clamp or the second clamp.

[0039] In this embodiment, the upright is positioned above the first clamp 13; the first clamp is an irregular U-shaped clamp base 13 with a longer upper part and a shorter lower part; the second clamp 14 is a symmetrical U-shaped clamp base with equal upper and lower parts; wherein, the irregular U-shaped clamp base or the symmetrical U-shaped clamp base includes an upper clamping plate near the top surface of the steel beam flange, a lower clamping plate near the bottom surface of the steel beam flange, and a side plate near the side surface of the steel beam flange. One end of the threaded adjusting screw 12 is fixed to the bottom surface of the upper clamping plate of the irregular U-shaped clamp base; the other end of the threaded adjusting screw 12 passes through the side plate of the symmetrical U-shaped clamp base and is threadedly fixed to the symmetrical U-shaped clamp base by a first self-locking nut 11.

[0040] In a more specific embodiment, the pole body is a telescopic pole, which includes an inner pole fixedly connected to the pole fixing base and an outer pole disposed above the inner pole and telescopically fixed to the inner pole; a tie member 2 is provided on the outer pole, so that the lifeline can be fixed by the tie member 2 on multiple parallel adaptive adjustable steel structure lifeline pole devices.

[0041] In one specific embodiment, the inner rod is a lead screw 3; the outer rod is a sleeve, and a second self-locking nut 4 is provided at the bottom of the sleeve. The sleeve is fixed to the lead screw by the second self-locking nut 4, so that the total height of the pole body 10 can be controlled by adjusting the relative position of the inner rod and the outer rod.

[0042] In this embodiment, at least two stiffening plates 5 are fixed at equal intervals between the side wall of the lead screw and the upright fixing base 6. In the specific embodiment shown in the figure, three stiffening plates are provided to ensure the stability of the upright body 10.

[0043] In this embodiment, two symmetrical fixing holes are respectively provided on the first clamp and the second clamp. A circular clamping block 9 is welded and fixed to the bottom of the fastening bolt 7. The circular clamping block 9 is fastened between the fastening bolt and the top surface of the steel beam flange. The fastening bolt 7 is threadedly fixed to the third self-locking nut 8 provided above the fixing hole, so that the circular clamping block 9 further ensures the tightness of the fastening bolt 7 and the steel beam flange.

[0044] In a specific embodiment, the adaptive adjustable steel structure lifeline pole device of this embodiment comprises a pole body, a first clamp, a second clamp, a threaded adjusting screw, fastening bolts, first, second, and third self-locking nuts, stiffening plates, and a telescopic rod. The pole body is a vertically arranged tubular structure, divided into inner and outer rods. The lower part of the pole is the inner rod, which is connected to the first clamp at the bottom, and the upper part is the outer rod, on which a tie rod is provided for connecting the lifeline rope.

[0045] The first clamp is a U-shaped clamp base (longer at the top and shorter at the bottom) with an irregular U-shaped clamp base, fitted with stiffening plates and fastening bolts. The upright body is welded to the U-shaped clamp base via three stiffening plates, making the assembly more stable. Two fastening bolts on the U-shaped clamp base pass through the upper surface of the base and each has a self-locking nut for tightening and preventing loosening. Circular block-shaped clamps are installed on the bolts, and these clamps are designed to be welded to the fastening bolts. The circular block-shaped clamps are designed to fit the upper surface of the steel beam flange, typically being a circular block structure for better conformity to the steel beam flange.

[0046] The second clamp is a U-shaped clamp base (symmetrical U-shaped clamp base), equipped with a threaded adjusting screw, a self-locking nut, and fastening bolts. A threaded hole is located at the center of the upper surface of the U-shaped clamp base, allowing the threaded adjusting screw to pass through and connect to the U-shaped clamp base (longer at the top and shorter at the bottom). A self-locking nut is mounted on the threaded adjusting screw. This design allows both the first and second clamps to move horizontally, accommodating steel beams with various flange widths. The second clamp also has two fastening bolts, with the same construction as the fastening bolts on the first clamp.

[0047] The telescopic pole is equipped with a second self-locking nut. By rotating the second self-locking nut, the parallel movement of the nut is converted into the vertical movement of the pole, which can push the pole body up and down, thereby realizing the adjustment of the pole height to adapt to the site environment and reduce the utilization of site space.

[0048] The adaptive adjustable steel structure lifeline pole device in this embodiment can be used in the following manner:

[0049] Preparation before installation: Based on the approximate width of the steel beam flange, adjust the screw using the threaded adjustment rod. Adjust the distance between the first and second clamps initially, and place them on the flange of the steel beam. At the same time, check whether the self-locking nuts (first, second, and third self-locking nuts) of each device move smoothly.

[0050] Installation Process: First, erect the upright pole body. Rotate the second self-locking nut on the telescopic pole device to move it up and down, adjusting it to a suitable height for the on-site construction environment. Then, tighten the self-locking nut to fix the height. Next, place the lower base of the first clamp against the lower surface of the steel beam flange. Then, adjust the fastening bolt by moving it up and down using the self-locking nut until the circular clamping block is fully and tightly fitted against the upper surface of the steel beam flange. Finally, rotate the third self-locking nut on the fastening bolt to tighten it. Finally, rotate the first self-locking nut on the threaded adjusting screw to move the U-shaped clamp base horizontally along the threaded adjusting screw. When the side of the U-shaped clamp base is against the steel beam flange, rotate the self-locking nut again to achieve clamping and self-locking. The adjustment method for the fastening bolts on the second clamp is the same as that for the first clamp.

[0051] Usage and maintenance: During construction, regularly check the tightness of the clamping device. If it becomes loose, replace the self-locking nut immediately. Tighten the fasteners. When encountering steel beams with different flange widths, follow the installation process described above and adjust the distance between the upright fixing base ⑥ and the second clamp ⑩. After construction, loosen the self-locking nuts ④ and ⑧. Disassemble the second clamp ⑩ and clean and maintain all the devices for future use.

[0052] As described above, the adaptive adjustable steel structure lifeline pole device provided in this embodiment has the following beneficial effects:

[0053] Versatility: The horizontally movable design between the first and second clamps allows it to adapt to steel structures with flanges of various widths, greatly improving the applicability of lifeline pole bases, reducing the need for customized bases due to different flange widths, and lowering construction costs.

[0054] Convenience: Most of the devices in this design are bolted and adjustable, allowing for quick installation and adjustment on-site, thus improving construction efficiency. The telescopic pole design makes the height of the lifeline poles adjustable, adapting to various construction environments. It also improves the transportation and retrieval of the lifeline poles, significantly reducing the space required for transportation and on-site storage during retrieval.

[0055] Stability: The design of clamping and fixing the flange plate by setting fastening bolts on both sides of the first and second clamps and threaded adjusting screws greatly improves the safety of the lifeline pole and ensures its stability when subjected to external forces such as the pulling force of construction personnel, effectively protecting the safety of construction personnel.

[0056] In short, the horizontally movable design between the first and second clamps allows the clamping device to adapt to steel beams with different flange widths, and the telescopic pole design allows the pole body to flexibly adapt to the site environment, reducing the waste of space resources.

However, those skilled in the art should understand that various modifications can be made to the adaptive adjustable steel structure lifeline pole device proposed in the present invention without departing from the scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the contents of the appended claims.
