DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an easy-to-use and inexpensive corrugated material-incorporated wall structure applied to a building wall.

[0002]

2. Description of the Related Art Conventionally, as a construction method of a wooden building, a frame construction method, a two-by-four construction method, a panel construction method and the like are known. In the framing method, a concrete foundation is built on the ground, a foundation is placed on top of it, pillars are erected on it, and floors and roofs are framed using horizontal members called beams, girders, and bollards. It will be built and will be provided with braces and walls to resist horizontal forces caused by earthquakes and winds. The two-by-four construction method (frame wall construction method) is a construction method based on the fact that a building is integrated with a floor plate and a load-bearing wall, and a type of box is assembled. The feature is that it can be easily joined. In the panel construction method, floors, walls, etc. are formed by assembling panels on both sides of a rectangular frame consisting of vertical frames, horizontal frames, and inclined frames, with flat plates stretched to the size of the frame. The panel is manufactured in advance in a factory, transported to a construction site, and assembled.

[0003] There are two types of walls in wooden buildings: those that support vertical loads (such as loading loads), those that bear horizontal loads (horizontal forces due to earthquakes and winds), and those that do not.
In each case, there are a method using the above-mentioned frame construction method, a method using the two-by-four method, and a method using the panel method.

[0004] As for the frame construction method, in addition to the traditional true walls and large walls, those shown in FIGS. 5 and 6 are generally used. FIG. 5 shows a non-bearing wall, in which a plurality of horizontal rims 1c are attached to the vertical pillars 1a, 1a and studs 1b, and a gypsum board 2, a cloth 3 and the like are provided on the inner surface of the rim 1c. It is stretched. FIG. 6 shows a load-bearing wall, in which structural plywood 4, 4 is stretched on both inside and outside surfaces of vertical pillars 1a, 1a and studs 1b like the non-bearing wall. Although not shown in the drawings, the bearing wall is often provided with a brace.

[0005] A wall made by this method has a high degree of freedom and can meet various requests of a client, and is suitable for building a high-quality wooden house. In addition, there is a problem that the construction is complicated, and it is necessary to rely on experienced persons, and the number of experienced persons gradually decreases, and it becomes difficult to maintain and inherit the method.

Further, the pillar 1a, the stud 1b, and the rim 1c include:
Semi-timber such as cedar, rice pine, and rice hemlock may be used, and as time passes, they tend to be deformed such as shrinkage and curvature, creating gaps in each part, impairing airtightness, and reducing indoor temperature. -There are problems that it is difficult to adjust the humidity and that the inclination and the like are out of order. In order to prevent this, it is necessary to reduce the interval between the adjacent pillars 1a, the studs 1b, and the rim 1c, and thus there is a problem that a large number of pillars, studs, and rims are required. Moreover, when the gypsum board 2 and the plywood 4 are joined in the longitudinal direction, their ends need to be positioned on the upper surfaces of the pillars 1a, the studs 1b, and the rim 1c, and fixed with nails or the like. If these gaps are wide, it is necessary to cut off the protruding portion, so that a short material cannot be used, and there is a problem that the loss of the material increases accordingly. Further, when piping / wiring is required in the space of the wall, it is difficult to hold and fix them because the interval between the studs 1b and the rim 1c is large. There is a problem that it must be cut.

Next, the wall by the two-by-four construction method is basically the same as that by the frame construction method. For example, in the case of a load-bearing wall, as shown in FIG.
A plurality of vertical frames 5a having a thick plate shape of inches are erected in parallel, and plywoods 4, 4 are stretched on the inner and outer surfaces of the vertical frames 5a. The vertical frame 5a is supported on the upper surface of the floor or the like via a lower frame connecting the lower ends thereof, and a horizontal upper frame connecting the upper ends thereof is stretched or crosses the vertical frame 5a diagonally. A brace is provided, and between the adjacent vertical frames 5a, 5b, a similar thick plate-shaped horizontal anti-roller is provided as necessary (both are not shown).

According to this method, the building is integrated by the floorboard and the wall structure, and a kind of box is assembled.
As described above, there is an advantage that the types of members are small and the members can be easily joined to each other with nails and hardware. However, the number of man-hours is comparatively small, and a shaft There are almost the same problems as those by the construction method.

Third, as shown in FIG. 8, for example, as shown in FIG. 8, the wall by the panel method is formed on both sides of a rectangular frame 6 made of a vertical frame, a horizontal frame, and an inclined frame, which is manufactured in a factory. To
A panel 7 on which plywoods 4 and 4 having a size corresponding to the frame 6 are stretched is erected on a base or a floor. Therefore, there is an advantage that the operation is simplified and the efficiency is improved, the construction period is shortened, and the operation can be performed without an experienced person.

However, as in the case of other construction methods such as frame and two-by-four, semi-raw wood such as rice pine and rice hemlock is used for the frame 6, so that deformation such as shrinkage and bending occurs with the passage of time. It is easy to cause, gaps occur in each part, airtightness is impaired, it is difficult to adjust the indoor temperature and humidity,
There is a problem that the inclination or the like may be out of order. Furthermore, the panel 7 produced in the factory has a problem that the volume is large, the transportation burden is large, and the dimensional adjustment on site is almost impossible.

[0011]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned drawbacks of the conventional wooden building walls, to be easy to construct, to be inexpensive, and to require experienced persons. Less irregularity, good heat insulation and airtightness, low loss of material, easy installation and fixing of wiring and piping in the wall space, less burden on transportation, and corrugation for easy on-site dimensional adjustment It is an object of the present invention to provide a molding-incorporated wall structure.

[0012]

In order to achieve the above object, a wall structure with a built-in corrugated material according to the first aspect of the present invention vibrates at a constant frequency in both horizontal directions with respect to one vertical plane. The highest point (1) of the adjacent wave on the front side of the corrugated material (10) formed by molding a plant piece via an adhesive having a wave height of
The surface material such as plywood (4, 4) parallel to the vertical surface is brought into contact with the lowest point (12) of the adjacent wave on the back side of 1) and the corrugated material (10), and is corrugated so as to be joined. The molding material (10) is incorporated between face materials such as two plywoods (4, 4). Note that the plant pieces include powdered materials such as wood, straw, bamboo, kolyan, reed, kayak, hemp, paper, etc., fibrous materials, chip-shaped materials, leaves, and the like.

According to a second aspect of the present invention, the plant pieces constituting the corrugated molding (10) of the first aspect are made of any one of powdery, fibrous and chip-shaped wood or a mixture of two or more of them. Or that including them.

According to a third aspect of the present invention, in addition to the configuration of the first or second aspect, the corrugated material (10) is arranged so that the direction of the continuous waves of the corrugated material (10) is substantially horizontal. It is characterized by having.

The symbols in the parentheses correspond to the symbols described in the drawings and the embodiments of the invention described later.

According to the first aspect of the present invention, an integrated corrugated material is incorporated between the two plywoods instead of the studs, the rim and the vertical frame, so that the construction is simple. No special experience is required, and construction costs are reduced. Further, since it is made of a plywood or a corrugated material that is hardly deformed even with the passage of time, gaps and irregularities due to shrinkage and deformation are unlikely to occur. Moreover, the highest point, which is the crest of plywood and corrugated material,
Since the lowest point to be the bottom of the wave is combined, especially when the wavelength of the wave-shaped material is applied that has a wavelength (for example, 150 mm) sufficiently smaller than the arrangement interval of the conventional studs / vertical frames, Even without anti-rolling and bracing, the stiffness as well as the proof stress are significantly higher than those of the conventional one.

Further, the wall space is partitioned into small pieces by the plywood and the corrugated material, and a plurality of small spaces having small gaps and excellent airtightness are formed. The burden is reduced. Conversely, if desired, a small partitioned space between the walls can be used as a ventilation path for cold or hot air. Further, the small partitioned space can be effectively used for inserting and fixing wiring and piping. For example, the air-conditioning piping meandering in a hairpin shape in the wall space portion also has a straight portion inserted into each of the spaces parallel to the wave front line, and a cutout or a hole in only a relatively thin plate-like portion that the bend portion traverses. It can be easily laid by drilling. In addition, since the interval between the wave front lines that abuts on and supports the plywood is small, the end protruding from the wave front line is shortened, and a short material can be used, thereby reducing the loss of the plywood and the like.

According to the second aspect of the present invention, in addition to the effects of the first aspect of the invention, powdery, fibrous, or chip-shaped wood is used as the plant piece, which is stable in supply and quality. An inexpensive and high quality corrugated material embedded wall structure is provided.

According to the invention of claim 3, claim 1 or 2
In addition to the functions and effects of the invention, the buckling strength is sufficiently high even if the corrugated material becomes longer in the vertical direction because the second moment of area is higher than studs and vertical frames with small width and thickness. ,
In particular, the rigidity and proof strength against vertical loads (such as loading loads) are large.

[0020]

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a partial perspective view showing a corrugated material-embedded wall structure according to an embodiment of the present invention, FIG. 2 is a cross-sectional view showing a method for producing a corrugated material, and FIG. 3 is another embodiment of the present invention. FIG. 4 is a perspective view showing an embodiment, and FIG. 4 is a perspective view showing a third embodiment of the present invention.

As shown in FIG. 1, the corrugated material-embedded wall structure according to the embodiment of the present invention vibrates at the same cycle in both horizontal directions with respect to one vertical plane (at a constant wavelength, The highest point 11 of the adjacent wave on the front side of the wave-shaped material 10 and the adjacent wave on the back side of the wave-shaped material 10 having a constant wave height (eg, 45 mm) having a constant wave height (for example, 45 mm) formed by molding a plant piece via an adhesive. The surfaces of the plywoods 4 and 4 parallel to the vertical plane are in contact with the lowest point 12, respectively, and are connected by nails or the like. Moreover, the corrugated material 10 is arranged so that the direction in which the waves are connected is substantially horizontal, that is, the wave front line Z shown in FIG. 1 is vertical.

The corrugated material 10 is formed by an adhesive.
It is manufactured by molding plant materials such as powdered materials such as straw, bamboo, kolyan, reed, kaaya, hemp, paper, wood, etc., fibrous materials, chip-shaped materials and leaves. In addition, as a plant piece, supply and quality are stable, and an inexpensive and good-quality corrugated material 10 is used.
It is preferable to use one composed of or containing a mixture of at least one of powdery, fibrous, and chip-shaped wood, or containing them.

This wall structure is provided between two plywoods 4,4.
Since the integrated corrugated material 10 is incorporated in place of the studs, the torso, and the vertical frame, the construction is simple, no special experience is required, and the construction cost is reduced. Moreover, since it is composed of the plywood 4 and the corrugated material 10 that are not easily deformed even with the passage of time, gaps and deviations due to shrinkage and deformation hardly occur.

Further, between the two plywoods 4 and 4, a wavy forming material 10 is incorporated so that a wave front line Z is vertical, instead of a stud, a waist edge and a vertical frame having a small width and thickness. Plywood 4,
4 and the highest point 11 serving as the wave crest and the lowest point 12 serving as the wave bottom of the corrugated material 10 are joined by nails, so that the second moment of area is higher than that of the conventional example, and the corrugated material is vertical. Even if it becomes longer in the direction, the buckling strength is sufficiently high, and particularly the rigidity and proof strength against a vertical load (such as a load) are large. Therefore, in particular, the wavelength of the corrugated molded material 10 is sufficiently smaller than the arrangement interval of the conventional studs or vertical frames (for example, 150 m).
If a material having m) is applied, the stiffness as well as the proof strength will be significantly higher than those of the conventional one, even if there is no anti-rolling or bracing. In addition, it is also possible to use as a non-bearing wall, and in that case, a cloth can be stuck without using a gypsum board.

Further, the space partitioned by the plywood 4 and the corrugated material 10 is small, so that wiring and piping can be easily inserted and suitable for fixing them. In addition, for example, the air-conditioning piping meandering in the shape of a hairpin in the wall space portion also has a straight line portion inserted into each space in parallel with the wave front line Z, and only a portion where the bend portion crosses is cut or drilled. It can be laid easily (not shown). In addition, the wavelength of the corrugated material 10 is short, the plywood 4 is in contact, and the wave front line Z
Is small, the end portion of the plywood 4 protruding from the wave front line Z is shortened, a short material can be used, and the loss of the plywood 4 is reduced. In addition, if powder, fibrous, or chip-shaped wood having a stable supply and quality is used as a plant piece, an inexpensive and high-quality corrugated material-embedded wall structure is provided.

Further, the wall space is partitioned into small pieces by the plywoods 4 and 4 and the corrugated material 10, and a plurality of small spaces having small gaps and excellent airtightness are formed. It is improved and the air conditioning burden is reduced. Conversely, if desired, a small partitioned space between the walls can be used as a ventilation path for cold or hot air.

Although the above-mentioned wall structure is described on the assumption that it is constructed at a building site, it does not matter at all if it is manufactured at a factory as a panel of a panel construction method. Therefore, in the case of the construction site construction, since a plurality of plywood 4 and the corrugated molding 10 can be superimposed, the volume at the time of transportation is reduced as compared with the wall panel of the conventional panel construction method, and at the time of the site construction. Dimension adjustment is easy. On the other hand, the panel produced by the factory has advantages that the work at the site can be simplified and made more efficient, the work period can be shortened, and the work can be easily carried out without an experienced person.

In producing the corrugated molded material, the thickness obtained by cutting radiata pine as a plant piece is 0.2 to 0.2 mm.
Strands (thin wood pieces) each having a thickness of 0.4 mm, a width of 10 to 50 mm, and a length of 20 to 150 mm were dried with a dryer to a moisture content of 3% or less. To it was added 12% (as solids) of a melamine-urea resin mixture as an adhesive. The strand F treated as described above was placed on a net in an irregular layered manner, and another net was placed thereon, and the layered strand was sandwiched between two nets.

The strand F sandwiched between the nets is shown in FIG.
As shown in the figure, a steam injection port having a diameter of 2 mm is sandwiched between molds M having a corrugated uneven surface formed at intervals of 30 mm, and compressed at a pressure of 25 kg / m ² and steam at a temperature of 160 ° C. Injected twice for 5 seconds alternately up and down, and fixed for 4 minutes. When released from the mold, it can be used in the present invention, and has a strong and excellent durability, a plate thickness of 12 mm, a wave height of 45 mm, and a wavelength of 150.
As a result, a wavy molded material 10 of mm was obtained.

The corrugated material 10 is erected on 45 mm studs (not shown) arranged in parallel at 910 mm intervals.
Plywood 4, on the front and back of the crest 11 and the bottom 12, respectively
4 is brought into contact with one another, and an automatic nailing machine is used to drive and join a 21-mm nail to form a corrugated molded material built-in wall structure according to an embodiment of the present invention.

Further, another embodiment of the present invention will be briefly described. The corrugated material 10 has, for example, as shown in FIG. 3, studs 1b, 1b arranged at both ends of the corrugated material 10. As shown in FIG. 4, the corrugated members 10, 10 are arranged side by side in the thickness direction of the wall in one wall structure. Various configurations according to the purpose are possible, such as a vertical corrugated material mixed with a stud / vertical frame (not shown).

[0032]

According to the first aspect, between two plywoods,
Since the integrated corrugated material is incorporated in place of the studs / vertical frames, the construction is simple, no special experience is required, and the construction cost is reduced. Further, since it is made of a plywood or a corrugated material that is hardly deformed even with the passage of time, gaps and irregularities due to shrinkage and deformation are unlikely to occur. In addition, since the highest point, which is the crest, of the two plywoods and the corrugated material and the lowest point, which is the corrugated bottom, are combined, the wavelength of the corrugated material is particularly larger than the conventional spacing between the studs and vertical frames. If a material having a sufficiently small wavelength (for example, 150 mm) is applied, the stiffness as well as the proof strength will be significantly higher than those of the conventional one, even if there is no anti-rolling or bracing.

In addition, the wall space is partitioned into small pieces by plywood and a corrugated material, and a plurality of small spaces having small gaps and excellent airtightness are formed. The burden is reduced. Conversely, if desired, a small partitioned space between the walls can be used as a ventilation path for cold or hot air. Further, the small partitioned space can be effectively used for inserting and fixing wiring and piping. For example, the air-conditioning piping meandering in the shape of a hairpin in the wall space also has a straight portion inserted in each of the spaces in parallel with the wave front line, and a cutout or a hole in only a relatively thin plate-like portion that the bend portion traverses. It can be easily laid by drilling. In addition, since the interval between the wave front lines that abuts on and supports the plywood is small, the end protruding from the wave front line is shortened, and a short material can be used, thereby reducing the loss of the plywood and the like.

According to the second aspect of the present invention, in addition to the effects of the first aspect of the present invention, powdery, fibrous, or chipped wood, which is stable in supply and quality, is used as a plant piece. An inexpensive and high quality corrugated material embedded wall structure is provided.

According to the invention of claim 3, according to claim 1 or 2,
In addition to the functions and effects of the invention, the buckling strength is sufficiently high even if the corrugated material becomes longer in the vertical direction because the second moment of area is higher than studs and vertical frames with small width and thickness. ,
In particular, the rigidity and proof strength against vertical loads (such as loading loads) are large.
