Mantang scaffold, also known as mantanghong scaffold, is a construction technology for building scaffold. Compared with other scaffold systems, the full scaffold has a high density. In short, it is to put up shelves all over the house. The full scaffold is more stable than other scaffolds.

characteristic

The full hall scaffold is mainly used for the decoration construction of the top of buildings with high floors and large bays, such as single-storey plants, exhibition halls and gymnasiums. It is composed of vertical bar, cross bar, diagonal bracing, cross bracing, etc

After the full scaffold is used, the interior wall decoration above 3.6m will not be calculated separately, while the masonry scaffold of the interior wall will still be calculated according to the provisions of the interior scaffold.

The use of full scaffold depends on its height. When the clear height of the ceiling is less than 3.6m, the decorative scaffold will not be calculated regardless of the decoration process adopted by the ceiling.

When the clear height of the ceiling is between 3.6m and 5.2m, the decorative scaffold of the ceiling shall be calculated according to the quota of the full scaffold layer. When the clear height of the ceiling is above 5.2m, the decorative scaffold of the ceiling shall calculate two quota items: the basic layer and the additional layer.

For the common cast-in-situ concrete beam and slab, the steel pipe and fastener at the lower side of the formwork are supported by the formwork in the actual construction process, not the full scaffold. When calculating the quantity of scaffold with beam and slab structure, the column and beam components shall be calculated according to the calculation rules, and the corresponding scaffold quota shall be applied.

For the formwork support structure used for concrete cast-in-situ construction in buildings, steel or wood beams are generally assembled into formwork brackets, and steel or wood rods are used to build scaffolds to form bracket support, and cooperate with steel formwork for concrete construction.

Building formwork support frames are generally classified according to their materials:

1. Wooden building formwork support frame: the main and auxiliary edges and support poles of all support frames are made of wood;

2. Formwork support system for tall buildings: refers to the formwork support system for concrete components at the construction site of the construction project, where the formwork support height exceeds 8m, or the erection span exceeds 18m, or the total construction load is greater than 15kn / ㎡, or the concentrated line load is greater than 20KN / M.

3. Rigid building formwork support system: all materials used for the support frame are steel materials and have scalability; The new building formwork support structure has the advantages of energy saving, material saving, cost saving, ensuring project quality and improving construction efficiency. It can be recycled, has high strength, and has good verticality and flatness of concrete. It has implemented the basic national policy of energy conservation and emission reduction.
