Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper-made building member protection material for protecting a floor material from scratches, frays, etc. generated by directly laying a material (mainly a plywood) for protecting a building floor.

[0002]

2. Description of the Related Art A conventional paper building material protection material is mainly used to improve cushioning and air permeability by laying a sheet cut into a rectangular shape from a roll between a floor material and a protection material. I have. The surface is embossed (embossed) to give a three-dimensional structure. In order to compensate for the reduced strength, a film made of polyolefin resin is applied to one or both sides of the sheet. Affixed.

[0003] When laying a sheet of the above-mentioned material, a certain distance between the wall and the above-mentioned material sheet is set so as not to hinder the installation of a later skirting board (decorative board at the bottom of the inner wall and in contact with the floor). It is necessary to open. Depending on the place to be used, the extra width of the sheet of the above-mentioned material needs to be cut or bent, and a floor protection material such as a plywood is placed thereon, and the edges are fixed with tape having low adhesive strength.

[0004]

In conventional embossing, paper is passed between a convex mold made of plastic or the like and a concave mold made of metal, and the paper is lifted by applying pressure. When pressurized, the fibers of the paper are stretched and split. It also means that the strength of the paper itself, that is, the strength, is greatly reduced. To increase the strength, it is necessary to attach a film, but on the other hand, the film is difficult to disintegrate with the used paper, and is a contraindicated product specified in the "Used Paper Standard Quality Standard" of the Used Paper Recycling Promotion Center.
For this reason, if only paper is used, it is difficult to reuse the recovered paper through a possible used paper collection route. It does not fit the intentions and purpose of the laws related to the recycling-oriented society currently being promoted. There is a lot of waste in terms of both resources and energy.

A plywood generally used as a protective material for flooring has a width of 30 dimensions and a length of 60 dimensions (about 910 m).
m · 1820 mm) in many cases. This is the result of adjusting to the dimension by the shakukan method. In this case, naturally, the paper-made building member protective material for protection is required to have a size larger than that in view of the application. In the longitudinal direction, the length can be freely changed to cut out from the roll, but the width is approximately 930 to 1000 mm. However, since the above materials are used in various places such as Japanese-Western style rooms, stairs, corridors, etc., the size required for each place is not uniform. Further, in order to install a skirting board or the like later, it is necessary to provide the paper-made building member protection material at a certain distance from the wall. Processing such as cutting off or folding the end of the material sheet is required depending on the application. When used in a wide place, the method of stacking the above material sheets can be used, but this method cannot be used in a corridor or stairs. It is a difficult task to fold and cut a sheet that exceeds the length with both arms extended straight. It has been pointed out that it takes time and effort in the conventional work.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and the embossing is not performed, and the embossing area of a paper-made architectural member protective material sheet is reduced, thereby maintaining the strength of the paper itself. It is an object of the present invention to provide a processing method that facilitates the work of bending, cutting, and stacking the excess width of the sheet, with the object of ensuring cushioning force and air permeability.

[0007]

Means for Solving the Problems In order to achieve the above-mentioned object, a paper-made building member protecting material of the present invention is laid between a floor material and the protecting material in a building construction process.
This is a band-shaped sheet made of a single piece of paper cut into a rectangle from a roll, and has a three-dimensional structure in which a linear embossing is performed from above or below in a forward direction with respect to a longitudinal direction.

In such a configuration, it is desirable to reduce the pressurized area of the paper in the embossing process as compared with the embossing process, for the purpose of suppressing fiber separation of the paper and securing sufficient strength of the paper alone. . In addition, in order to maintain the cushioning force and the air permeability, it is required to process the contact surface with the floor material so that the contact surface is limited to the shape of the lower sharp line. Depending on such a structure, even when used alone, the effect is expected as a non-slip.

The paper building material protection material of the present invention is desirably a material that can be used as a single piece of paper and can be recovered and reused by using a private or administrative waste paper recovery route at the time of disposal. Therefore, it is effective to form a plurality of the above-mentioned embossing at intervals of 10 mm to 100 mm. If the interval is smaller than this, the strength cannot be maintained, and if the interval is longer than that, the buffering power and air permeability are lost. With such a configuration, it is possible to adapt to the construction of a recycling-based society that is currently being promoted. Incineration does not emit toxic gas and contributes to reduction of industrial waste, but also leads to resource saving and energy saving during manufacturing.

When the paper building material protection material of the present invention is actually used, the width dimension required depending on the place is not uniform. In addition, an interval for installing a baseboard and the like must be provided with the wall, and the interval is desirably suppressed to approximately 15 mm or less. For the reasons described above, the width of the above material is 930 to 10
When it is used in a wide place, it is necessary to stack the above-mentioned material sheets, and to cut out or fold an extra width in a narrow place. For the above reasons, it is effective to cut the embossing interval to about 50 mm.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on embodiments with reference to the drawings. FIG. 1 is an upper perspective view showing the configuration of a paper building member protection material of the present invention, and FIG. 2 is an enlarged vertical sectional view showing an embodiment of a sheet 101 thereof.

As shown in FIG. 1, a sheet 101 of a paper-made architectural member protection material 1 is wound in a roll 2 shape. In addition, the material is provided with a plurality (17 in FIG. 1) of linear embossings 3 at regular intervals (10 mm to 100 mm) from above or below in the forward direction with respect to the longitudinal direction. Reference numeral 4 denotes contact surfaces 4a and 4b of the floor member 6 with the protective member 7 in FIG. The bonding surface 4 with the protective member 7 is kept from being separated from the fibers by the pressurization at the time of manufacturing, so that the strength of the sheet 101 is maintained. Reference numerals 5a, 5b, and 5c denote lower sharp lines of the embossing 3, which come into contact with the floor material 6 below the lines. Due to this three-dimensional structure, the space 8 between the sheet 101 and the floor material 6 shown in FIG.
a, 8b and embossing 3 and space 9 on protective material 7 of flooring 6
a, 9b, and 9c are created, and the air permeability between the flooring 6 and the protective material 7 is increased to provide a cushioning force.

FIG. 3 is an exploded view of the structure of a conventional paper building member protection material. The embossed sheet 10 is often used. However, in order to form a three-dimensional structure, 11 points on the front and 12 points from the back are pressed. On the other hand, since the strength of the paper is reduced by the above processing, a film 13 of a polyolefin resin is applied to the sheet 10 for the reason of maintaining the strength.
A method of sticking on one side or both sides is used. In addition, the installation state of the above-mentioned materials is not different from that of FIG. 5 described later.

FIG. 4 is a longitudinal sectional view showing an embodiment of the paper-made architectural member protective material sheet 101 of the present invention, and FIG. 5 is an enlarged sectional view when the material edge is bent. Lower cusp lines (points in the figure) 5a, 5a generated by the embossing process
b, 5c, 5d and 5e, 5
Only d and 5e. Sheet 10 of paper building material protection material
Since the required width of 1 differs depending on the place where it is used, a surplus width 14 always occurs at the time of installation. The sheet 101 of the above-mentioned material needs to have a sufficient space 16 with respect to the wall 15 so as not to hinder the work such as the installation of the baseboard. Therefore, it is necessary to bend the margin 14 based on the line AA. At this time, the embossing serves as a guide at the time of cutting / folding work, and facilitates the work which has conventionally been difficult with paper-made building member protection materials. The material sheet 101 folded in FIG. 5 is folded with reference to the line AA, and the floor material 6 is formed only below the lower cusp line 5 generated by the embossing.
Contact with. Therefore, the space 8 generated between the floor material 6 and the material sheet 101, and the protection material 7 for the material sheet 101 and the floor material 6
An intervening space 9 is created to provide cushioning and ensure air permeability.

FIG. 6 is a top perspective view showing an embodiment of the material edge portion. The sheet 101 of the paper building material protection material laid between the floor material 6 and the protection material 7 such as a plywood requires a sufficient space 16 with the wall 15. The interval 16 is the sum of the width of the baseboard 17 to be installed later and the width required for the work. If the interval 16 is too narrow, the above-mentioned work is hindered. On the other hand, if the interval 16 is too wide, the role of protecting the flooring material 6 itself is lost. Therefore, the interval 16 is desirably suppressed to approximately 15 mm or less. Further, the protective material 7 and the sheet 101 of the paper building material protective material may be completely overlapped.

Further, the protective material 7 and the sheet 101 need to be fixed with a tape 18 having low adhesive strength with their edges overlapped. This is to prevent the floor material 6 from being damaged by the displacement of the protective material 7 and the sheet 101. At this time, the sheet 101 needs to have a sufficient space 16 with the wall 15 or the like, but it is necessary to cut, fold, or overlap the extra width of the sheet 101 generated at that time as necessary. However, especially when a paper-made building member protection material is used in a narrow place such as a corridor, the means of stacking cannot be used, and cutting is difficult. Therefore, in general, it is often bent as shown in FIG.

FIG. 7 is an upper perspective view showing a situation in which the paper-made building member protective material is overlaid. As mentioned above, the sheet needs to be processed with extra width depending on where it is used,
When used in a wide area, a method of overlapping as shown in the figure is adopted. When the sheets 101 and 102 of the above materials are stacked,
The embossing 3a, 3b of the material sheet 101 and the same sheet 10
By superimposing 2e 3e and 3f, the above-mentioned material sheets can be blended more easily, and the work of overlapping in parallel can be facilitated.

[0018]

Since the present invention is configured as described above, it has the following effects.

According to the present invention, it is possible to protect the flooring material from being scratched or abraded by the protective material depending on its shape, and the above-mentioned processing can reduce the area to be embossed. The strength can be kept high compared to embossing.

Further, a three-dimensional structure is made possible by the unevenness created by the embossing of the processing. Thereby, a sufficient space can be provided between the protective material such as a plywood and the floor material, and the air permeability and the cushioning force can be secured.

[0021] Since the present invention is a single piece of paper, it should be
It can be easily reused by using the administrative waste paper collection route.

Since the roll is cut into a rectangle, the length can be adjusted according to the location. Also, regarding the width, by using the line embossed by the above processing as a reference for the crease, even if the length to be bent exceeds the width of the extended arm, it can be easily bent.

Further, when the material sheets are stacked, the embossed portions formed by the above processing are overlapped, so that the sheets can be easily stacked in parallel and the two sheets can be easily adapted.
