Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of steel structure construction, in particular to a steel structure installation life line stand column. BACKGROUND

[0002] Steel structure is widely used in high-rise buildings, large-span venues such as gymnasiums, airports, bridges, industrial plants, etc. due to its high strength, light weight, good seismic performance, short construction period and other characteristics, and promotes the development of installation technology. Steel structure components are mostly prefabricated in factories and assembled on site, and need to be installed through hoisting, welding, bolt connection and other processes, all of which are high-altitude operations, and the safety requirements for the construction site are extremely high. At the same time, with the increase of building height and span, the weight and installation difficulty of components are significantly improved, and the safety risk of traditional construction technology is highlighted, which forces the safety technology to develop in the direction of standardization. Steel structure installation is mostly high-altitude operation, which is prone to falling accidents. When hoisting heavy components, the existing technology usually uses temporary fixing hooks and ropes to tie life lines to steel structure components. If the hooks are aged, damaged, misused or affected by wind, it may cause component overturning, personnel falling, etc., resulting in object impact or mechanical injury. In addition, bad weather can also affect the operation of the hoisting personnel. If the hooks are not fixed firmly or are not used properly, it is easy to cause falling accidents, low installation efficiency, low work efficiency and low operability.

[0003] Therefore, it is necessary to provide a steel structure installation life line stand column to solve the above problems. SUMMARY

[0004] The purpose of the present application is to provide a steel structure installation life line stand column to solve the problems of low safety of temporary fixing parts, low installation efficiency, low work efficiency and low operability.

[0005] To achieve the above purpose, the present application provides the following technical scheme: A steel structure installation life line stand column, comprising a left stand column and a right stand column, wherein the bottom of each of the left stand column and the right stand column is fixedly installed with a column bottom fixing assembly, the column bottom fixing assembly comprises a fixing part, a screw rod one, a fixed cover plate, a triangular plate diagonal brace, a screw rod two and a support sleeve, the fixing part is C-shaped, the screw rod one is threadedly installed on the fixing part, the fixed cover plate is fixedly installed at the bottom of the screw rod one, and the fixed cover plate is located inside the fixing part, the triangular plate diagonal brace is fixedly installed on the left stand column and fixedly installed on one side of the top of the fixing part, the screw rod two is fixedly installed at the bottom of the fixing part, and the support sleeve is threadedly installed on the screw rod two, the life line storage assembly is fixedly installed on the outer side of the left stand column near the top, and the life line fixing assembly is fixedly installed on the outer side of the right stand column near the top.

[0007] Preferably, the roller is penetrated through the left stand column at one end away from the reel, and a screw thread is arranged on the roller at a position outside the left stand column.

[0008] Preferably, the lifeline fixing assembly comprises two symmetrically arranged fixing base plates, a third screw rod, a rotating block, a mounting piece, an upper pressing roller and a lower pressing roller, the fixing base plates are fixedly installed on the right stand column, the third screw rod is fixedly installed between the two fixing base plates, the rotating block is screwedly installed on the third screw rod, the mounting piece is fixedly installed on the rotating block, and the upper pressing roller and the lower pressing roller are rotatably installed in the mounting piece.

[0009] Preferably, a clamping rack is fixedly installed outside the mounting piece, the rotating shaft of the upper pressing roller is penetrated through the mounting piece at both ends, and slide grooves are arranged on both sides of the mounting piece to cooperate with the rotating shaft to slide up and down.

[0010] Preferably, an end plate one is fixedly installed at one end of the rotating shaft of the upper pressing roller away from the gear, a spring is fixedly installed at one end of the end plate one, the spring is sleeved on the rotating shaft of the upper pressing roller, an end plate two is fixedly connected to one end of the spring, and the end plate two is slidably installed on the rotating shaft of the upper pressing roller.

[0012] Preferably, one end of the lifeline away from the reel is located at the upper end of the lower pressing roller, and the bottom of the upper pressing roller is crimped on the lifeline.

[0013] The technical effects and advantages of the present application are as follows: 1. The C-shaped fixing piece and the fixing cover plate are clamped on the upper flange of the I-beam through the first screw rod, and the lower flange is supported by the second screw rod and the support sleeve, forming a stable fixing mode of "up-down clamping", solving the problem of easy loosening of the traditional temporary hook; the triangular plate diagonal brace further enhances the connection strength of the stand column and the fixing piece, can resist the wind impact and the pulling force of personnel in construction, ensures that the stand column has no risk of overturning in the high-altitude environment, and is especially suitable for high-rise building steel structure installation scenes.

[0014] 2. The combined pressure of the upper and lower rollers, coupled with the meshing transmission of the gear and rack, precisely adjusts the clamping force on the lifeline. The spring and end plate 2 automatically lock the upper roller in place, preventing the lifeline from slipping due to vibration or external forces. Compared to traditional rope lashing, this structure reduces the chance of the lifeline breaking or loosening, providing continuous and reliable fall protection for workers working at height.

[0015] 3. The column base fixing assembly can be fixed to the steel beam by screwing a screw, without the need for welding or complex tools. A single person can quickly complete the installation of a single column. The reel and handle design of the lifeline storage assembly improves the efficiency of releasing and recovering the lifeline, solving the time-consuming problem of traditional manual rope dragging. It is especially suitable for adjusting the movement line during the installation of steel structures in large-span venues.

[0016] 4. The entire device is made of high-strength alloy materials. The integrated design of the triangular plate diagonal brace and the column improves the compressive performance and can maintain stable mechanical properties in various environments. It is suitable for open-air or high-temperature operation scenarios such as bridges and industrial plants. The height-adjustable function of the support sleeve can adapt to I-beams of different specifications without the need for customized accessories. BRIEF DESCRIPTION OF THE DRAWINGS
