Product Description

>>>

The turnbuckle scaffold is a new type of scaffold, which was introduced from Europe in the 1980s. It is an upgraded product after the bowl buckle scaffold. It is also known as chrysanthemum disc scaffold system, plug-in disc scaffold system, wheel disc scaffold system, buckle disc scaffold, layer frame and Leia frame, because the basic principle of the scaffold is invented by layher company in Germany and is also called “Leia frame” by people in the industry. It is mainly used for lighting frame and background frame of large-scale concert.), The socket of this kind of scaffold is a disk with a diameter of 133mm and a thickness of 10mm. 8 holes are set on the disk φ 48 * 3.2mm, Q345A steel pipe is used as the main component. The vertical rod is welded with a disc every 0.60m on a certain length of steel pipe. This novel and beautiful disc is used to connect the cross rod with a connecting sleeve at the bottom. The cross bar is made of a plug with a pin welded on both ends of the steel pipe.

Scaffold is a working platform set up to ensure the smooth progress of each construction process. It is divided into external scaffold and internal scaffold according to the erection position; According to different materials, it can be divided into wood scaffold, bamboo scaffold and steel pipe scaffold; According to the structural form, it is divided into vertical pole scaffold, bridge scaffold, portal scaffold, suspended scaffold, hanging scaffold, cantilever scaffold and climbing scaffold. Scaffolds for different purposes shall be selected for different types of engineering construction. Most of the bridge supports use bowl buckle scaffolds, and some also use portal scaffolds. Most of the floor scaffolds for the construction of the main structure use fastener scaffolds, and the longitudinal distance of the scaffold poles is generally 1.2 ~ 1.8m; The transverse distance is generally 0.9 ~ 1.5m.

Compared with the general structure, the working conditions of scaffold have the following characteristics:

1. The load variation is large;

2. The fastener connection joint is semi-rigid, and the rigidity of the joint is related to the fastener quality and installation quality, and the performance of the joint varies greatly;

3. The scaffold structure and components have initial defects, such as initial bending and corrosion of members, large erection dimensional error, load eccentricity, etc;

4. The binding variation of the connection point with the wall to the scaffold is large. The research on the above problems lacks systematic accumulation and statistical data, and does not have the conditions for independent probability analysis. Therefore, the value of structural resistance multiplied by an adjustment coefficient less than 1 is determined by calibration with the previously adopted safety factor. Therefore, the design method adopted in this specification is semi probabilistic and semi empirical in essence. It is the basic condition for design and calculation that the scaffold meets the structural requirements specified in this specification.
