Problems solved by technology

The conventional maintenance methods for the wall are watering and smearing of curing fluid. Water cannot remain on the wall for a long time, and after pouring in an outdoor environment, if the outdoor temperature is low, the concrete temperature of the wall column will be low, which is not conducive to the maintenance of concrete. , Concrete walls and columns have poor maintenance effect

Embodiment 1

[0039] The present invention is a kind of concrete wall coating maintenance method, comprises the following steps:

[0040] 1) Concrete is poured in the wall pouring mold, and after the concrete is finally set, the formwork is removed; when the formwork is removed, the coating curing solution is started;

[0041] 2) Mix the raw materials of the coating curing solution in proportion and put them into the watering can, and use the watering can to spray the surface of the walls and columns;

[0042] 3) During the spraying process of step 2), the spraying method of the wall is to start spraying from the lower part of the wall to the upper part of the wall, after spraying to the upper part of the wall, start spraying again along the unsprayed position of the lower part of the wall to the upper part of the wall until it is covered. The film curing liquid covers the entire surface of the wall, and travels along the side edge parallel to the wall when spraying;

[0043] 4) After the ...

Embodiment 2

[0069] The present invention is a kind of concrete column coating maintenance method, comprises the following steps:

[0070] 1) Concrete is poured into the column pouring mold. After the concrete is finally set, the formwork is removed; when the formwork is removed, the coating curing solution is started;

[0071] 2) Mix the raw materials of the coating curing solution in proportion and put them into the watering can, and use the watering can to spray the surface of the walls and columns;

[0072] 3) During the spraying process of step 2), the spraying method of the column is to start spraying from the lower part of the column to the upper part of the column, after spraying to the top of the column, start spraying again along the unsprayed position of the lower part of the column to the upper part of the column until it is covered. Membrane curing fluid covers the entire surface of the cylinder, and travels along the direction parallel to the axis of the cylinder when sprayin...

Embodiment 3

[0094] The difference between this embodiment and Embodiments 1 and 2 is that: when the plastic film is wrapped around the surface of the cylinder in a helical direction, the plastic film is stretched so that the plastic film is stretched; when the plastic film is wrapped around the cylinder, two layers are required.

[0095] Remove the plastic film, water retention layer, and water pipe after the 28th day after the plastic film wrapping is completed, and complete the maintenance process of the wall column. The formwork was removed 13 hours after the concrete was poured and the walls and columns were maintained. After step 2) the curing agent is sprayed, use hot air to heat the surface of the wall and column for 4 minutes.

Abstract

The invention relates to a film curing method of a concrete wall column. The film curing method is characterized by comprising the following steps of (1) casting concrete into casting molds of walls and columns, and removing a formwork after final setting of concrete; when the formwork is removed, preparing film curing liquid; (2) mixing the raw materials of the film curing liquid according to a ratio, loading into a spray pot, and enabling the spray pot to spray to the surfaces of the walls and columns; (3) in the spraying process in step (2), the spraying manner of a column body is to sprayfrom the lower part of the column body to the upper part of the column body, after spraying to the top end of the column body, spray from an unsprayed position of the lower part of the column body tothe upper part of the column body until the film curing liquid completely covers all the surfaces of the column body, wherein the spraying is performed along the direction parallel with the axis direction of the column body. The film curing method has the advantages that the defects of the prior art are overcome; the structural design is reasonable and novel.

Description

technical field [0001] The invention relates to a film-covered maintenance method for concrete wall columns, which belongs to the field of construction. Background technique [0002] Concrete curing is to artificially create certain humidity and temperature conditions, so that the newly poured concrete can be normal or accelerated to harden and increase its strength. The reason why concrete can gradually harden and increase strength is the result of cement hydration, and the hydration of cement requires certain temperature and humidity conditions. If the condition does not exist in the surrounding environment, the concrete needs to be cured manually. The conventional maintenance methods for the wall are watering and smearing of curing fluid. Water cannot remain on the wall for a long time, and after pouring in an outdoor environment, if the outdoor temperature is low, the concrete temperature of the wall column will be low, which is not conducive to the maintenance of concr...
