Scaffolding Scaffold refers to all kinds of supports erected on the construction site for workers to operate and solve vertical and horizontal transportation. It is a general term in the construction industry. It refers to the external wall, internal decoration, or places with high floor height that cannot be constructed directly on the construction site. It is mainly used for the construction personnel to work up and down, the maintenance of a peripheral safety net, and the installation of components at high altitudes. En bref, it means erecting scaffolds and scaffold materials. Materials usually include bamboo, bois, tuyau, or synthetic materials, etc.. Scaffolding is also used as formwork in some projects. En outre, it is also widely used in the advertising industry, municipal administration, transportation roads and bridges, mines, and other departments.
Scaffolds and formwork supports for different purposes are selected for different types of engineering construction. À présent, the bridge support frame
Most of the scaffolds use bowl buckle, and some also use portal scaffolds. The floor scaffolds for the construction of the main structure use fasteners
Most scaffolds are, and the longitudinal distance of scaffold poles is generally 1.2 ~ 1.8m; the transverse distance is generally 0.9 ~ 1.5m.
Advantages of portal steel pipe scaffold:
1) Standardization of geometric dimensions of portal steel pipe scaffold.
2) Reasonable structure, good mechanical performance, full use of steel strength, and high bearing capacity.
3) Easy assembly and disassembly, high erection efficiency, qui a sauvé le travail, time-saving, sûr, fiable, economical, and applicable.
Disadvantages of portal scaffold:
1) There is no flexibility in the frame size, and any change in the frame size must be replaced with another model of gantry and its accessories
2) The cross support is easy to break at the middle hinge point;
3) The shaped scaffold board is heavy,
4) Expensive portal steel pipe scaffold
Adaptability:
1) Structured scaffold
2) As the support frame of beam and plate frame (bearing vertical load);
3) Construct movable workbench;
