Concrete curing film covering device for building construction

Abstract

The invention discloses a concrete curing film covering device for building construction. The device comprises a vehicle-mounted walking device, a sweeping mechanism, a watering curing mechanism, a power mechanism, a supporting frame, a film laminating roller, a baffle, a hinge block, an extension plate, an electric push rod and a film pressing protection device. The sweeping mechanism is locatedon the left side of the top of the vehicle-mounted walking device, the watering maintenance mechanism is located on the top of the vehicle-mounted walking device, and the watering maintenance mechanism is located on the right side of the sweeping mechanism. According to the invention, the vehicle-mounted walking device moves forward; then, one end of the film on the film laminating roller is pressed at the bottom of the pressing roller; at the moment, the thin film on the film covering roller flatly covers the surface of the concrete, water can be collected in the thin film after film covering, a self-curing environment is prevented from being caused by water loss, the phenomenon that the concrete is dehydrated after pouring forming of the concrete is avoided, and the sufficient strength of the concrete is guaranteed.

Description

technical field [0001] The invention relates to the technical field of concrete maintenance, in particular to a concrete maintenance coating device for building construction. Background technique [0002] In building construction, the reason why concrete can gradually set and harden after pouring and tamping is mainly due to the result of cement hydration, and hydration requires appropriate temperature and humidity conditions. Therefore, in order to ensure that the concrete has suitable hardening conditions, To make its strength continue to grow, the concrete must be cured. [0003] After the concrete is poured, if the climate is hot and the air is dry in summer, if the maintenance is not carried out in time, the moisture in the concrete will evaporate too quickly and form a dehydration phenomenon, which will make the cement particles that have formed a gel body unable to fully hydrate and cannot be transformed into stable cement particles. Crystallization, lack of sufficie...

AI Technical Summary

Problems solved by technology

[0004] In some construction situations, such as the overall construction area is large and the construction speed is required to be high, and due to the limited weather conditions, the temperature is high and the evaporation is fast, the existing concrete that has been poured is closed first, closed The construction method of carrying out the film covering process after the overall completion of the surface cannot achieve the ideal construction effect. The specific surface closing project is large and time-consuming. The film is carried out after the surface closing is completed. The time between the two processes is concrete. The surface loses a lot of water, and it is relatively easy to produce surface cracks, which will affect the apparent quality of concrete.
