Problems solved by technology
From the actual implementation, it can be found that the above two methods have the following defects: first, multiple people are required to cooperate to complete the installation and disassembly of the steel wire rope, and the construction efficiency is low; second, the fixing method of the steel wire rope will cause irreversible damage to the main structure. It affects the quality of the structure, and the friction between the steel wire rope and the corners of the main structure can easily cause the wire rope to break, which poses a greater safety hazard; third, the length of the steel wire rope is affected by the position of the bolt hole on the main structure, and it is difficult to estimate the length , there is the problem of excessive investment in steel wire ropes, and the cost cannot be controlled; fourth, the labor and material investment is large, the construction cost is high, and the construction quality cannot be guaranteed

The invention discloses a gravity rotary clip fastening type suspension device and its installation and disassembly methods. The gravity swivel-fastened hitch consists of a straight rod. One end of the straight rod is provided with a hook and an external thread, and the external thread is screwed with a lock nut and is sleeved with a gasket. The other end of the straight rod is concavely provided with an accommodating groove and is installed with an end rod. The end rod is composed of an accommodating rod part and an outer rod part, and the outer rod part is heavier than the accommodating rod part. The accommodating rod part can be inserted into or moved out of the accommodating groove under the action of the rotation of the end rod. When the receiving rod part is embedded in the receiving groove, a "one" shape is formed between the end rod and the straight rod. When the accommodation rod moves out of the accommodation groove, a "T" shape is formed between the end rod and the straight rod. The invention is convenient to install and disassemble, can be used repeatedly, and has low cost.
Description
technical field [0001] The invention relates to a suspension device used on a construction site, in particular to a gravity-swivel fastening type suspension device and its installation and disassembly methods. Background technique [0002] The steel wire rope used to hang the safety net needs to be fixed before the concrete structure project adopts the inclined support method to tension the safety net on site. At present, the ways of fixing the wire rope mainly include the way of winding and locking the main structure and the way of back corrugated steel bar. The main structure of the winding lock is to pass the steel wire rope through the bolt hole of the main structure, so that the whole steel wire rope is wound and locked on the main structure. The back corrugated steel bar method is to set the back corrugated steel bar on the inner side of the main structure, and the double-strand iron wire passes through the bolt hole to connect the steel wire rope on the outside of th...
