Description

Technical Field

[0001] The present invention belongs to the technical field of construction engineering, and particularly relates to a method for making and hoisting an unconventional movable lifting sling. The movable sling is mainly used for indoor hoisting projects. There are no hanging rails and hanging points for indoor hoisting in industrial and public construction projects. For example, if there is an I-beam in the room, a movable sling can be invented to be directly fixed on the lower flange plate of the I-beam. The movable sling directly solves the hoisting problem of having nowhere to hang the fall chain when hoisting equipment and objects indoors. The movable sling is fixed on the lower flange plate of the I-beam of the original structure by two steel plates in a clamp-type manner. After the clamp clamps the I-beam, it is fastened with high-strength bolts to prevent the sling from loosening and falling off. The use of the movable sling of the present invention does not require drilling holes or welding hoisting node plates on the original main structure, and does not damage the original structure. The manufacture is simple, the installation is convenient, the construction is fast, and it is safe and reliable. Background Art

[0002] In the construction of building projects, there are sometimes some indoor hoisting projects, such as adding a steel structure mezzanine or installing electromechanical equipment indoors. When hoisting the mezzanine steel structure platform or electromechanical equipment, it is impossible to enter the room for crane hoisting. Often, the ceiling steel beam is used as a hoisting point. However, the steel beam is the main load-bearing structure, and the design does not allow welding of hoisting hangers on the steel beam. Only mechanical connection can be used. The present invention mainly invents a simple movable sling for this situation. The movable sling is directly clamped on the lower flange plate of the ceiling I-beam in the form of a clamp. The clamp is fixed by two high-strength bolts. The clamp is made of 14 thick steel plate and the bolts are high-strength bolts with a diameter of Ø16. The tensile and shear resistance of the steel plate and bolts reaches more than 20 tons, which can far meet the indoor hoisting requirements. The movable sling is easy to disassemble, can be moved to another place for hoisting at will, can be reused, is very convenient to construct, is simple to manufacture, has extremely low manufacturing cost, and has great social promotion value. Summary of the Invention

[0003] The purpose of the present invention is to provide an unconventional lifting and hoisting sling for indoor environments where cranes cannot be operated. This movable sling can effectively complete the lifting of indoor equipment, components, and objects, saving crane hours and making the lifting simple and economical. The movable sling is mainly made of two 14-inch thick steel plates and is fixed with two Ø16 high-strength bolts during installation and hanging. The movable sling can be directly clamped on the lower flange plate of the ceiling I-beam through a clamp. After the sling is fixed, the fall chain is directly hung on the movable sling, and the fall chain and sling are used to complete the lifting work. The movable sling is easy to disassemble, can be moved to another location for lifting, can be reused, is very convenient to construct, is simple to manufacture, has extremely low production costs, and has great social promotion value.

[0004] The finished product manufacturing method and construction steps of the present invention are as follows: (1) Production of movable slings: Made of Q235 steel plate with a thickness of 14mm, two pieces are used to form a fixture. Three holes are drilled on the fixture with an electric drill, two of which are used for bolts and one for hanging the lifting wire rope. The finished product is shown in the detailed drawing. (2) Installation of movable sling: Before installing the movable lifting fixture, first connect the two plywood plates with a high-strength bolt. The clamp can be opened and closed freely. The clamp clamps the two sides of the lower flange plate of the indoor ceiling I-beam. After adjusting the position, install another high-strength bolt. Then tighten the two bolts to prevent loosening. After the bolts are tightened, the clamp opening is locked to form a stable lifting point. (3) Hoisting with movable slings: After the movable sling is firmly installed, it can be used for lifting. First, pass the lifting wire rope through the lifting hole reserved in the movable sling, hang the manual chain hoist hook on the lifting wire rope, and then you can start the lifting operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0005] Figure 1 This is a construction diagram of a movable hoisting device, including a floor slab 1, an I-beam 2, a fixture steel plate 3, bolt holes 4, high-strength bolts 5, a steel wire rope 6, and a fall chain 7. DETAILED DESCRIPTION

[0006] The following describes the embodiments of the present invention in conjunction with the accompanying drawings: (1) Production of movable slings: Made of Q235 steel plate with a thickness of 14mm, two pieces are used to form a fixture. Three holes are drilled on the fixture with an electric drill. Two holes are used to pass Ø16 high bolts for fixing, and one hole is used to hang the lifting wire rope. The finished product style is shown in the detailed drawing. (2) Installation of movable sling: Before installing the movable lifting fixture, first connect the two plywood plates with a high-strength bolt. The clamp can be opened and closed freely. The clamp clamps the two sides of the lower flange plate of the indoor ceiling I-beam. After adjusting the position, install another high-strength bolt. Then tighten the two bolts to prevent loosening. After the bolts are tightened, the clamp opening is locked to form a stable lifting point. (3) Hoisting with movable slings: After the movable sling is firmly installed, it can be used for lifting. First, pass the lifting wire rope through the lifting hole reserved in the movable sling, hang the manual chain hoist hook on the lifting wire rope, and then you can start the lifting operation.
