For different engineering situations, according to the conditions of each enterprise, the correct selection of different building templates is an important experience in using building templates. Many years of practice have summed up a lot of valuable experience. It is necessary to adapt to local conditions, make use of existing resource conditions, and constantly innovate and develop new resources; not only to ensure quality, not to use unqualified building templates, but also to spend more funds to update all new building templates.
1) The slab building template is recommended to use the entire multi-layer board (wood, bamboo can be), try to use phenolic cladding 15~18MM thick multi-layer building template. The edge of the building template is damaged after repeated use, and cutting is performed in time to ensure that the edge of the multi-layer board is flat.
2) Beam and column building formwork should adopt medium-sized composite building formwork. Due to the variation of beam and column section, it is not suitable to use multi-layer board cutting.
3) The wall form can be assembled into a large formwork with a medium-sized composite building formwork, and the whole form can be used to make a large formwork, or a full-steel large formwork can be used. Generally, the same type of high-rise building groups should be unified as much as possible to ensure a high usage turnover rate.
4) Make full use of the old multi-layer board and short residual wood after multiple cutting to make various sizes of medium and small wood combination formwork for various medium and small cast-in-place concrete parts, but these woods must be ensured. The ribbed height of the sizing template is uniform, the board surface is flat, the weight is light, the rigidity is good, and it is not easy to be damaged.
5) Make full use of existing small steel molds. And to meet the requirements of clear water and concrete. According to the experience of some companies, the surface layer of the combined small steel mold can be covered with plastic plates or other thin plates, used on floors, shear walls or other components.
6) The arc-shaped wall is increasing day by day, and the curvature is variable. After processing the shaped arc template, it will be changed several times, and it will cost a lot of work. Recently, some projects have applied the "curvature-adjustable curved template" to a large area. The arc template of any radius is adjusted by the adjuster, and the effect is remarkable, and it is worthy of popularization and application.
7) The core cylinder of super high-rise or high-rise buildings should adopt “hydraulic climbing formworkâ€. The climbing mold process combines the advantages of large formwork and sliding formwork. It can be upgraded layer by layer with construction speed, saving construction speed and saving space and Tower crane hoisting, safety at high altitude, no external scaffolding, construction, especially suitable for the construction of concrete inner cylinder of steel structure.
