What is a construction screw? In the scaffolding support system, the application of building screws is more and more widespread, because the building screw is retractable within a certain range, and it is relatively simple and convenient in actual construction.
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 support the load. 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, the building screw can be divided into upper support and lower 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. The chassis is at the lower part, and the chassis may not be folded.
2. It can be divided into hollow lead screw and solid lead screw according to the material used. The lead screw of hollow lead screw is made of thick-walled steel pipe, which is lighter. The solid lead 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.
