Description

Technical Field

[0001] The utility model relates to an anti-slip steel beam hoisting protection device and belongs to the field of hoisting construction. Background Art

[0002] With the rapid development of the domestic cultural and sports industries, people have an increasing demand for diversified building functions and greater requirements for activity space. Compared with concrete structures, steel structures have light weight, good ductility, and strong seismic performance. In addition, they are widely used in large-span structures, process plants, logistics warehouses, and public buildings due to their own advantages. The sharp escalation of conflicts between natural resources and the environment and the continuous emergence of energy issues have also brought broad application prospects for green and environmentally friendly steel structures.

[0003] During the construction of steel beams, slings are usually used for binding and hoisting, and the angle of the slings for steel beam hoisting shall not be less than 60 degrees. Binding hoisting is used for secondary beams and supports. The binding must be firm, and the wire ropes are tied with angles (with angle steel in semicircular steel pipes) to prevent the wire ropes from breaking. This traditional hoisting method, due to the repeated use of slings for hoisting, although corner protectors are used in construction to protect the slings and I-beams, the corners between the slings and the steel beams will be more or less worn. If the worn ropes are not replaced in time, it is very easy to cause safety hazards such as the fall of the steel structure hoisting; on the other hand, the I-beams are in close contact with the slings, and the shaking of the hoisting will cause the slings to wear the I-beams, destroying the anti-rust paint of the I-beams, and easily causing construction quality problems such as steel corrosion. In addition, in the traditional hoisting construction method, the slings and I-beams are completely connected to each other by friction generated by gravity. There is a construction safety hazard of sling slipping during construction. Therefore, the lifting point of the I-beam cannot be accurately positioned during the hoisting. The I-beam cannot maintain a horizontal state during the hoisting process, which increases the difficulty of hoisting into place. It is impossible to achieve high-precision hoisting construction of the I-beam, which greatly reduces the construction efficiency of the I-beam hoisting and installation. Utility Model Content

On the other hand, it also avoids the wear of the slings on the I-beam steel beam, which damages the anti-rust paint of the I-beam steel beam leaving the factory and causes the construction quality problem of steel rust. Through the centering measuring ruler on the device and the corresponding construction method, the lifting point of the I-beam steel beam during hoisting is accurately positioned, so that the I-beam steel beam remains in a horizontal state during the hoisting process, which greatly reduces the construction difficulty of hoisting into place and realizes the high-precision hoisting construction of the I-beam steel beam.
