[0002] In construction projects, in order to meet the needs of society, the state encourages increasing the prefabrication rate of buildings, and the use of prefabricated components is becoming more and more common.

[0003] There are many types of prefabricated components, including prefabricated components with door openings. Since these components are disconnected at the door openings, they are easily damaged during demoulding, hoisting and transportation, and the hanging beams at the door openings are prone to breakage and cracking.

[0004] Most of the existing supporting steel beams are made of channel steel or angle steel. Since the door openings of prefabricated components with door openings have many sizes and are similar from project to project, such supporting steel beams can only be used in one project and are relatively simple. After the project is completed, it is difficult to apply them to other door opening components, resulting in waste. In addition, the large number of processing operations causes a waste of labor. For this reason, people have invented a door opening support tool with adjustable length.

[0005] The existing patent number is CN213509684U, and the patent name is a utility model patent for a prefabricated component door opening support tool. It records that it includes a first end connection plate, a second end connection plate, a connection end, a connection rod and a sleeve. The first end connection plate is used to be fixedly connected to one side of the door opening, the second end connection plate is used to be fixedly connected to the other side of the door opening, the connection end is fixedly connected to the first end connection plate, one end of the sleeve is connected to the second end connection plate, the other end of the sleeve is threadedly connected to one end of the connection rod, and the other end of the connection rod is detachably connected to the connection end. The prefabricated component door opening support tool provided by the utility model can support door openings of different sizes, is easy to operate, and has low cost.
