Description

Concrete maintenance tectorial membrane instrument

Technical Field

The utility model relates to the technical field of concrete curing devices, in particular to a concrete curing and film covering tool.

Background

After the concrete structure is poured, if the concrete structure is maintained in hot weather and air drying in time, moisture in the concrete can be evaporated too fast to form a dehydration phenomenon, so that cement particles which form gel cannot be fully hydrated, cannot be converted into stable crystals, lack of sufficient cohesive force, and accordingly flake or powder falling can occur on the surface of the concrete. Further, when the concrete does not have sufficient strength, premature evaporation of water causes large shrinkage deformation and cracks due to drying shrinkage. Therefore, the curing of the concrete at the initial stage after the concrete is poured is very important, and the curing should be performed immediately after the concrete is finally set.

Concrete curing is a sub-project which takes the longest time and has the greatest influence on the quality of concrete. Concrete curing generally adopts several methods such as watering natural curing, spraying film curing, plastic film wrapping curing and the like. The concrete curing mechanisms are all to keep the concrete moist and avoid water loss so as to achieve the curing purpose. During the concrete curing period, the humidity and temperature control of the concrete should be emphasized, the exposure time of the concrete on the surface is reduced as much as possible, the exposed surface of the concrete is covered tightly in time, and tarpaulin, plastic cloth and the like can be adopted for covering to prevent the evaporation of the water on the surface.

At present concrete placement back uses the polyethylene plastic film to keep wet the maintenance more, and nevertheless lay in the polyethylene film and mostly be artifical roll shop, and the workman can't go up the people and cover the plastic film of keeping wet on the concrete structure of just pouring completion, does not in time keep wet the cover and can cause the concrete to lose water sooner, gives later stage concrete quality production craze and intensity reduction risk.

The present invention has been made based on such a situation.
