Background
The concrete pouring construction comprises wall surface construction, column body construction and the like, wherein the construction process comprises the steps of firstly building steel bars, then building templates, fixing the templates and then pouring concrete.
The reasons for the slurry leakage of the template in the building process are as follows: the material of the template does not meet the requirement; the adjacent templates are uneven and are not tightly spliced; the longitudinal and transverse vertical supports are not firm, and cannot bear the pressure measurement when concrete is poured, so that the phenomena of external expansion and die running are generated; over-dilution of concrete; the vibration time of the vibrating rod is too long at the local part; the slump of concrete is relatively large; uneven ground, etc.
The existing prevention measures for slurry leakage include: completely blocking the pores on the template; filling gaps of a bottom die of a cast-in-place plate, filling gaps with paint putty, and filling gaps of side dies of walls, beams and columns by using double-sided adhesive tapes; the mortar leveling base is adopted for the root gaps of the side forms of the column and the wall; the sand rate is increased; reducing the vibration time, etc.
Therefore, the damage of the slurry leakage of the template in the building pouring process is very large, the existing preventive measures waste manpower and materials, and the quality of the building wall can be changed if the property of the concrete is changed.
In addition, in concrete construction in building engineering, a large amount of mortar remains on the formwork after concrete pouring, and the mortar is tightly attached to the surface of the formwork and is difficult to clean. In general, a constructor cleans mortar on the surface of a template by using a putty knife, but the partially cleaned template cannot meet the requirements, so that great waste of human resources is caused; for a smooth surfaced form to be produced, the adhesion to the concrete form also results in the concrete form sticking to the concrete.
