Architectural screws are used in conjunction with steel pipes and scaffolding in the construction of engineering buildings, which can adjust the height of scaffolding and pipe racks, balance the support of heavy objects, and load-bearing. With the rapid development of real estate and three-dimensional transportation, the use of construction screws is also increasing rapidly.
Types of construction screw:
1. According to the application site, it can be divided into upper support, lower support and tube support.
① The upper bracket is used at the upper end of the column steel pipe, the chassis is at the upper end, and the chassis is folded;
② The undercarriage is used at the lower end of the column steel pipe in the construction of the building.
③ The tube holder is on the parallel steel pipe, and the chassis bears a half-moon-shaped notch.
2. The construction screw is divided into hollow screw and solid screw according to the material used. The screw of the hollow screw is made of thick-walled steel pipe and is lighter. The solid screw is usually made of round steel and heavier.
3. Ordinary lead screw and leg wheel top support; The lead screw is generally galvanized and used in the lower part of the movable scaffold to facilitate the construction process; the ordinary lead screw is used to support and stabilize the construction of the building.
4. Solid lead screw can be divided into hot-rolled lead screw and cold-rolled lead screw according to the production process of lead screw. The appearance of the hot-rolled lead screw is beautiful, and the cost is slightly higher; the appearance of the cold-rolled lead screw is not beautiful, and its cost is also slightly lower.
The above are some of the contents of the construction screw introduced by Xiaobian, I hope to help you! In fact, in actual life, there are other names for construction screws in some places, such as oil support, top support, bottom support, etc. In fact, they all refer to construction screws. I hope everyone can understand!
