Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for finishing walls of buildings using single-sided corrugated cardboard.

The general structure of corrugated board is a corrugated paper core with a paper liner glued to one or both sides, with air spaces segmented in parallel between the core and the liner. Therefore, it has some heat and sound insulation properties.

However, since it is made of paper as a whole, it has poor water and moisture resistance, and has the disadvantage that its mechanical strength is significantly lowered due to water absorption and moisture absorption, and its heat resistance is significantly impaired.

For this reason, cardboard has rarely been used as a heat or sound insulation material in building materials, such as building finishing materials.

However, the present inventor focused on the characteristics of single-sided corrugated board. That is, one side of single-sided corrugated board is a flat surface due to the liner, but the other side is a very finely corrugated surface. In addition, single-sided cardboard can be rolled up into a roll, making it convenient to carry and very easy to work with.

Furthermore, the present inventors have proposed that the liner and/or core be made of a synthetic resin sheet such as a synthetic resin film or synthetic resin cloth, or a metal sheet such as aluminum foil of a predetermined thickness, either alone or laminated with paper, etc. We have succeeded in producing corrugated cardboard at low cost using a corrugating machine.

According to the corrugated board made of the above-mentioned new material, water resistance and moisture resistance, which were disadvantages of conventional corrugated board, are improved, and mechanical strength (compressive strength, bursting strength, surface strength, etc.) can be further improved.

On the other hand, when interior finishing is done on a base such as exposed concrete, PC board, or ALC board, the entire base is usually coated with finishing mortar, but the heat and sound insulation properties are not satisfactory.

For this reason, in the past, gypsum boards, plywood, asbestos cement boards, calcium silicate boards, etc. were attached to the base surface using wood bricks, gypsum-based inorganic adhesives, etc., or lightweight steel frames and frame timber frames were constructed. Construction work was being done, such as attaching decorative boards on top.

However, all of these heat-insulating and sound-insulating materials are heavy, bulky, difficult to work with, and expensive.

The present invention was made in view of the above-mentioned circumstances, and aims to provide a wall finishing construction method that makes it possible to construct a wall structure with excellent heat insulation and sound insulation properties at a low cost by skillfully utilizing the special structure of single-sided corrugated cardboard. The purpose is

The construction method of the present invention uses a single-sided corrugated board made by pasting a liner on one side of a corrugated core, and fixes the liner surface of this single-sided corrugated board to the underlying wall surface so that the corrugated surface of the core faces the finished wall side. A wall finishing surface is formed by applying a plastering material to the corrugated surface of the core.

The material for the liner of the above single-sided corrugated board is as follows:
Paper, cloth, film, thin plywood, thin metal plate (foil), etc. can be used alone or in a laminate.

In particular, cloth alone or a laminate with paper, or a laminate of paper and a synthetic resin film are suitable. General cloths may be used as the cloth, but flat yarn cloth and splint yarn cloth made of synthetic resin have excellent water and moisture resistance.
Even when nailed into the subsurface, the part through which the nail penetrates does not tear, making it ideal.

Further, as the material for the core, the same material as the above-mentioned liner can be used. Especially thickness 10μ
A core mainly made of aluminum foil with a thickness of 200 μm to 200 μm is preferable because it has some rigidity and can block most of the amount of radiant heat transfer. Furthermore, the core, which is made of [paper] - [aluminum foil] - [paper], which is made by laminating the front and back sides of aluminum foil with paper in a sandwich pattern, can be easily laminated with liners, and can be easily used with a commercial corrugating machine. can be manufactured.

The side of the core opposite to the liner is preferably comprised of a paper layer. This is because the paper layer can appropriately absorb moisture from the finishing wall material and facilitate the finishing process. Moreover, if the paper layer is a cloth layer, cracks in the plastered wall can be prevented.

In addition, when carrying out the construction of the present invention, it is desirable that the paper portion constituting the single-sided corrugated board be subjected to flameproofing treatment.
For example, the paper portion is pre-soaked in a flame-retardant treatment agent such as an organic phosphoric acid-based treatment agent to make it flame-retardant. It is also desirable to treat the adhesive and the like with insect repellent such as BHC insect repellent before use.

On the other hand, it is preferable to use a single-sided corrugated board in such a way that the air in the air layer inside it is difficult to move due to convection. For example, the air layer can be completely blocked by crushing the application area of the core or closing the opening. In this case, the heat insulation and soundproofing effects can be further increased, and the waterproofing effect also becomes significant.

Embodiments of the present invention will be described below based on the drawings.

The figure is a cross-sectional structural diagram of a finished wall formed by the construction method of the embodiment of the present invention. The liner 2 of the single-sided corrugated board 1 is a reinforced paper liner made by laminating a polypropylene flat yarn cloth 4 on the front side of a paper 3.

The corrugated core 5 is made of paper-laminated aluminum foil made by laminating paper 7 on one side of aluminum foil 6, and the aluminum foil 6 side is bonded to the inner side paper 3 of the reinforced paper liner 2. and is in contact with the air layer 8. The aluminum foil 6 in this case is
The thickness is preferably 10μ to 200μ, especially when rigidity is required, 30μ to 200μ.

As shown in the figure, the single-sided corrugated board 1 constructed in this way is used as a finishing base material by placing the two reinforced liner surfaces against the base plate 9 surface and directing the corrugated surface of the core 5 toward the surface side.

Since the reinforced liner paper 2 is pasted with a cross 4, it has high rigidity and can be nailed to the base plate 9 without causing any tearing at the part where the nails pass through the cardboard. It also has heat insulation and sound insulation properties.

On the other hand, the wave front of the core 5 adds to the soundproofing effect,
The aluminum foil 6 in contact with the air layer 8 has the effect of preventing radiant heat. In addition, the air layer 8 that is subdivided in parallel between the core 5 and the liner 2 has a low thermal conductivity and excellent heat insulation properties, and because it is subdivided, air convection is prevented. This prevents a significant drop in insulation properties. Furthermore, it has an excellent sound absorption effect, that is, sound insulation property. Furthermore, this air layer 8
The action and effect of this will become more pronounced by crushing the core 5 at a proper location or closing the opening as described above.

A finished surface 11 is formed by applying a plastering material 10 such as cement mortar, plaster, plaster, etc. to the corrugated surface of the center core 5 of the single-sided corrugated board 1, which has been stretched on two sides of the base board 9 in this manner. In this case, the corrugated surface helps the wall plastering material 10 adhere, prevents the wall plaster from falling off, and the paper 7 portion of the corrugated surface appropriately absorbs moisture, thereby facilitating finishing work.

As explained above, according to the construction method of the present invention, a single-sided corrugated board with a special structure with heat insulation and sound insulation properties is used as the wall finishing base material, so finishing construction is easy and it has better heat insulation properties than before. Also, a wall structure with excellent sound insulation properties can be provided at low cost. In addition, single-sided corrugated cardboard made of synthetic resin cloth or aluminum foil of a specified thickness is expected to be used as a base material for even better heat and sound insulation finishes, making construction even easier.
