If the spacing of column formworks with large diameter is too large, the bearing capacity of each supporting part will be too large, which will lead to deformation. Therefore, the bearing force of column formworks should be considered in the design to reduce the distance between formworks, increase the number of supports, and ensure no deformation.In addition, when pouring concrete, the pouring is too fast and too high, which leads to the uneven interior and causes the deformation of the column formwork in terms of stress. Therefore, the pouring speed and height should be strictly required to ensure the even compaction.
Use sellotape to clean the concave and convex grooves in the column formwork.Unique (interpretation: unique, special) concave and convex groove design is one of the highlights of the formwork design, it can effectively prevent the leakage of slurry, but more than the turnover of the use of concave and convex groove will inevitably enter Concrete mortar, cleaning work is very complex.Before use, transparent tape can be pasted in the concave and convex groove, and then installed. Once entering the mortar, it is only necessary to tear and replace the transparent tape, and a small roll of transparent tape can solve the complicated cleaning work of the mortar in the concave and convex groove.
Construction formwork can be divided into cast-in-place concrete formwork, pre-assembled formwork, large formwork, jump formwork and so on.Is brief introduction of the combined steel formwork is as follows: combined steel formwork, is the modern formwork technology, with strong commonality, easy installation, turns many advantages, such as a new formwork "to the steel and wood, use it for cast-in-situ reinforced concrete structure construction, can be in advance according to the requirements of design spellers ChengLiang of large formwork, column, wall and floor, integral hoisting in place, also can be used in bulk dispersion method.
