Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is designed to provide sufficient curing strength during coating and curing, and to enable efficient curing even in a narrow space.

When applying mortar coating to the exterior walls of buildings such as wooden houses,
In order to save labor and shorten the construction period, a waterproof layer is formed on the surface of a wooden substrate such as plywood, fiberboard, or zoticle board, and then various mixed materials are added to the surface of this waterproof layer. Mortar base materials, which are coated with raw materials and cured and cured, have been widely used in the past.

Normally, a waterproof layer is formed by applying a waterproof paint such as a synthetic resin emulsion or synthetic rubber latex to the surface of a wooden substrate, but cement raw materials include cement, synthetic resin foam particles such as polyethylene and polystyrene, and various lightweight aggregates. A mixed material such as water and water is added, and this is applied to the surface of the waterproof layer using a roll coater, a thin gun, etc. In this case, in order to assimilate and bond the semi-fluid cement raw material to the surface of the waterproof layer, it is generally done to cure it by stacking it flat on crosspieces or by placing it on multi-tiered shelves after coating. It is being said.

However, with these curing methods, the work of stacking the wooden substrates or loading and unloading the wooden substrates on multi-tiered shelves is extremely complicated, and the space required for the number of wooden substrates is relatively large, and dry curing is difficult. It was inefficient because it took a long time. In order to shorten this drying time, it is known that after applying the cement raw material, it is rapidly dried to perform forced dehydration, and then the amount of water necessary for the hydration reaction of the cement is sprayed again for curing. This method has disadvantages such as insufficient strength of the cement after hardening and a large amount of energy cost.

In view of the various problems with the conventional curing methods for mortar base materials, the present invention has developed a base material for construction that can be efficiently cured in a narrow space, has sufficient hardening strength, and has minimal energy cost. The purpose is to provide a curing method for

The construction of the curing method for a building base material of the present invention that achieves this objective is to apply a waterproof paint to the surface of a wooden substrate to form a waterproof layer on the surface of the wooden substrate, and then add a mixed material. After applying a cement raw material to the surface of the waterproof layer, when stacking a large number of these wooden substrates vertically, fold a single band-shaped synthetic resin film or sheet between the upper and lower wooden substrates twice, The present invention is characterized in that the surface of the cement raw material is covered with this synthetic resin film or sheet to cure the cement raw material.

That is, as shown in the drawings illustrating the principle of the present invention, the base plate 1
A belt-shaped synthetic resin film or sheet 3 is folded double between each of the wooden substrates 2 stacked one above the other to cover the surface of the cement raw material 4 in a semi-sealed state. The cement raw material 4 is applied over the waterproof layer 5 previously formed on the surface of the wooden substrate 20, but the waterproof paint for forming the cement raw material 4 and the waterproof layer 5 may be the same as conventional ones.

As the synthetic resin film or sheet 3, synthetic resins such as 1.15 polyolefins such as polyethylene and polypropylene, polyesters, or fluorine-based resins, which have a low surface tension and are easily released from cement, are preferable. A film with a thickness of talometer or more or a sheet with a thickness of 500 micrometers or less is used, but it is of course possible to use other thicknesses. In addition, a synthetic resin film with a concavo-convex pattern formed on the surface (also referred to as a synthetic resin film) 3
By using this method, the uneven pattern is transferred to the surface of the cement material 4. In addition, it is also possible to use a loading machine equipped with a rewinding and running mechanism. In this embodiment, the wooden substrates 2 are stacked so that the cement raw material 4 faces upward, but it is also possible to stack them in the opposite direction. It is necessary to interpose a resin film or sheet 3.

As described above, according to the method for curing architectural base materials of the present invention,
Since the hydration reaction of cement during the curing period of natural drying is carried out in a semi-sealed environment using a synthetic resin film or sheet, it is possible to develop sufficient cement strength. In addition, since the wood substrate is double-ravaged directly via the synthetic resin film or sheet without using any crosspieces or shelves, the work is significantly simplified and the amount of curing per unit volume is greatly increased. This combined with the fact that no energy costs are required makes it possible to carry out extremely efficient 4S nutrition.

Furthermore, since the synthetic resin film or sheet is folded double between the wooden substrates that are stacked in one heap, the work of unloading the wooden substrates (mortar base material) from a certain direction after the cement hydration reaction is completed. 1J, and since only one side of the synthetic resin film or sheet is in contact with the wooden substrate, it is possible to clean and reuse only this one side, which is very convenient. .

[Claims] A waterproof coating is applied to the surface of the wooden substrate to form a waterproof layer on the surface of the wooden substrate, and then a cement raw material to which a mixed material is added is applied to the surface of the waterproof layer, and then this wooden substrate is applied vertically. When stacking a large number of sheets, one belt-shaped synthetic resin film or sheet is folded twice between the upper and lower wooden substrates, and the surface of the cement raw material is covered with this synthetic resin film or sheet, thereby making the cement raw material. 1.
