Description

Technical Field

[0001] This utility model relates to the field of steel structure construction technology, and in particular to a lifeline device for high-altitude installation of H-shaped steel beams. Background Technology

[0002] H-beams, as one of the main types of horizontal steel structure members, have significant characteristics and a wide range of applications. With the increasing prevalence of H-beam applications, a proper lifeline system must be installed during high-altitude construction to ensure construction safety and protect the finished components.

[0003] The conventional lifeline system for high-altitude installation of H-beams consists of welding 1.2-meter-high circular pipe or angle steel columns to the upper surface of both ends of the H-beam, followed by two steel wire rope lifelines. This method damages the coating of the H-beam during welding. After installation, subsequent steps such as column cutting and removal, weld area grinding, and coating reapplying are required, resulting in low efficiency, high cost, and compromised construction quality. Therefore, further optimization of the lifeline system for high-altitude H-beam installation is necessary. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned problems in the existing technology and provide a lifeline device for high-altitude installation of H-shaped steel beams.

[0005] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0006] A lifeline device for high-altitude installation of an H-beam includes two sets of parallel columns. The bottom of the columns is clamped on the upper flange of the H-beam, and the columns are perpendicular to the top of the H-beam. Two parallel steel wire ropes are installed between the two sets of columns.

[0007] The column comprises a steel base plate, a square tube, an angle steel, and a threaded rod. The square tube is vertically welded to the top of the steel base plate. The vertical edge of the angle steel is welded to the top of the steel base plate and the outer wall of the square tube. Two circular through holes are opened on the horizontal edge of the angle steel. Two nuts are welded to the top of the horizontal edge of the angle steel. Each nut is coaxial with and connected to a circular through hole. A threaded rod is screwed into each nut. The threaded rod cooperates with the steel base plate to clamp the upper flange of the H-shaped steel beam. Two parallel steel rings are welded on the square tube.

[0008] The bottom of the screw is fitted with a stepped circular fastening block to increase the contact area. The top center of the stepped circular fastening block is provided with a circular groove, and the bottom of the screw is fitted into the circular groove.

[0009] The top of the screw is flattened to form an operating part, and the operating part is provided with a circular insertion hole arranged radially along the screw.

[0010] A reinforcing plate is welded between the outer wall of the square tube and the top of the horizontal edge of the angle steel.

[0011] The square tube has a rectangular steel cover plate welded to its top.

[0012] The steel ring located at the lower part of the square tube is 60 cm away from the bottom of the steel base plate, and the steel ring located at the upper part of the square tube is 120 cm away from the bottom of the steel base plate.

[0013] The head of the wire rope passes through the steel ring, and the area where the head of the wire rope is bent 180 degrees and overlaps with the middle of the wire rope is clamped by four rope clamps.

[0014] The spacing between two adjacent rope clamps on the same wire rope is 6 to 7 times the diameter of the wire rope, and the distance between the rope clamp near the center of the wire rope and the end of the wire rope is greater than or equal to 140 mm.

[0015] The spacing between two adjacent sets of columns is less than or equal to 8 meters, and the drooping height of the steel wire rope in the middle is less than or equal to 100 millimeters.

[0016] The beneficial effects of this utility model are: the bottom of the column is clamped to the upper flange of the H-shaped steel beam by the cooperation of the screw and the steel base plate, which facilitates the installation and disassembly of the column, does not damage the surface structure and coating of the H-shaped steel beam, improves the construction efficiency of the lifeline device, and also facilitates the reuse of the lifeline device, thus reducing costs.

[0025] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] like Figures 1 to 6 As shown, a lifeline device for high-altitude installation of an H-beam includes two sets of parallel columns 1. The bottom of the columns 1 is clamped on the upper flange of the H-beam 4, and the columns 1 are perpendicular to the top of the H-beam 4.

[0027] Specifically, the column 1 includes a steel base plate 12, a square tube 11, an angle steel 13, and a screw rod 15. The square tube 11 is vertically welded to the top of the steel base plate 12. A rectangular steel cover plate 17 is welded to the top of the square tube 11. The vertical side of the angle steel 13 is welded to the top of the steel base plate 12 and the outer wall of the square tube 11. Two circular through holes are opened on the horizontal side of the angle steel 13. Two nuts 18 are welded to the top of the horizontal side of the angle steel 13. Each nut 18 is coaxial with and connected to a circular through hole. A screw rod 15 is screwed into each nut 18. The screw rod 15 cooperates with the steel base plate 12 to clamp the upper flange of the H-shaped steel beam 4.

[0028] The bottom of the column is clamped to the upper flange of the H-beam by a screw and a steel base plate, which facilitates the installation and disassembly of the column without damaging the surface structure and coating of the H-beam. This improves the construction efficiency of the lifeline device, facilitates the reuse of the lifeline device, and reduces costs.

[0029] To increase the friction between the bottom of the screw and the H-shaped steel beam, a stepped circular fastening block 19 is fitted on the bottom of the screw 15 to expand the contact area. A circular groove is provided at the top center of the stepped circular fastening block 19, and the bottom of the screw 15 is fitted into the circular groove.

[0030] The top of the screw 15 is flattened to form an operating part, so as to make it easy to rotate the screw 15 with a wrench; the operating part is provided with a circular insertion hole arranged radially along the screw 15, so as to make it easy to use a screwdriver or other tools to insert into the circular insertion hole to rotate the screw 15.

[0031] A reinforcing plate 14 is welded between the outer wall of the square tube 11 and the top of the horizontal edge of the angle steel 13 to improve the sturdiness of the square tube 11.

[0032] Two parallel steel wire ropes 2 are installed between the two sets of columns 1. Specifically, two parallel steel rings 16 are welded onto the square tube 11. The head of the steel wire rope 2 passes through the steel rings 16, and the head of the steel wire rope 2 is bent 180 degrees and the overlapping area with the middle of the steel wire rope is clamped by four rope clamps 3.

[0033] The steel ring 16 located at the lower part of the square tube 11 is 60 cm away from the bottom of the steel base plate 12, and the steel ring 16 located at the upper part of the square tube 11 is 120 cm away from the bottom of the steel base plate 12.

[0034] The spacing between two adjacent rope clamps 3 on the same wire rope 2 is 6 to 7 times the diameter of the wire rope 2. The distance between the rope clamp 3 near the center of the wire rope 2 and the end of the wire rope 2 is greater than or equal to 140 mm to prevent the end of the wire rope from slipping out of the rope clamp. A safety bend is reserved between two rope clamps at the head of the wire rope.

[0035] The spacing between two adjacent sets of columns 1 is less than or equal to 8 meters, and the sag height of the middle of the wire rope 2 is less than or equal to 100 millimeters. This ensures the effective operation of the wire rope 2.

[0036] Before hoisting the H-beam, the lifeline device should be installed on the ground. When construction workers are working at height, double-hook safety belts should be attached to the upper and lower steel wire ropes respectively to ensure the safety of construction workers working at height.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
