Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a wall joint material that can be used in prefabricated houses such as log houses. The present invention also relates to a wall structure and an assembled house using this wall joint material.

[Conventional technology]

In recent years, many prefabricated houses such as log houses have been constructed in villa areas. In a log house, cross members such as logs or square timbers are assembled in an alternating orthogonal manner and are fastened together to form the walls. The wall surface of a log house constructed in this way has an uneven surface that shows the contour shape of logs or square timbers, and the four corners of the wall surface have joints made of alternating logs or square timbers, so it is easy to design. It has an interesting shape.

[Problem to be solved by the invention]

However, although having an uneven wall surface is interesting from a design point of view, if you want to make the inner wall surface flat, for example, you can attach a board or the like to cover the uneven surface. It is necessary to apply a finishing material such as cloth to the surface. If this is done, the internal space will become narrower, which is not preferable. Moreover, the task of attaching the plate material to such an uneven surface is more difficult than the task of attaching it to a normal flat wall surface.

In view of this point, an object of the present invention is to provide a wall joint material that can have a wall surface in the shape of logs or square timbers on the outside, and that can form a flat wall surface on the inside. It is about realization. Another object of the present invention is to realize a wall structure using this new wall joint material, and furthermore, to realize an assembled house constructed of this wall structure.

[Means to solve the problem]

In order to solve the above problems, the present invention employs the following configuration as a wall joint material forming the corner portions of orthogonal wall surfaces. In other words, the part that appears on the outside of the wall joint material is a wide part made of logs or square timbers,
The part continuous to this wide part is a narrow part whose outer surface is flush with the wide part. And, on the upper surface of these wide parts and the narrow part that continues from this,
A notch is formed into which the lower surface of the wall joint member of the same shape, which is assembled by crossing these parts, can be fitted.

Further, in the present invention, the wall material is constructed by connecting the wall joint material having the above structure to one end or both ends of a plate material having the same cross-sectional shape as the narrow portion thereof.

Furthermore, in the present invention, the wall structure is constructed by assembling such wall materials alternately along orthogonal structural members such as vertically installed columns, and fixing them to the structural members after assembly. I am trying to configure it.

Furthermore, in the present invention, a prefabricated house is constructed having an outer wall employing this wall structure.

[Effect]

When the outer wall of a prefabricated house is formed using the wall joint material having the above-described structure, a joint structure in which logs or square timbers are assembled alternately will appear at the outer corner portions of the outer wall, as in the past. In addition, the outer wall has the same appearance as the uneven surface of logs or square timbers, as in the past. On the inside, on the other hand, a flat wall surface formed by one width section appears.

〔Example〕

The present invention will be described in detail below with reference to the drawings.

Figure 1 shows the outer corner portion of the outer wall surface of a log house to which the present invention is applied. As shown in the figure, the outer corner portion of the outer wall of the log house 1 is formed by an outer wall 2 in the cross-beam direction and an outer wall 3 in the inter-beam direction. These external walls 2.3
is constructed by assembling wall materials 4.5, each having the same shape, alternately along pillars 6 erected at the corner. Then, wall materials 4 stacked on the same plane
A sealing member 7 for sealing off the space between the two and between the wall materials 5 and the wall material 5 is arranged respectively.

Next, the structure of each part will be explained in detail. First, FIG. 2 shows the wall material 4 that constitutes one of the outer walls 2. As shown in FIG. This wall material 4 has a symmetrical shape. This wall material 4 is composed of a wall joint material 41 and a half material 42 connected thereto. The joint material 41 is formed from a log material, and has a log-shaped wide portion 411 at the tip. A narrow portion 412 having a vertically halved shape projects from one end of the wide portion 411 . Vertically divided surface 412a of this narrow portion 412
is perpendicular to the semicircular end surface 411a on the side of the wide part, and on the upper end side of these surfaces, there is a part that is perpendicular to the axial direction of the joint material, centered on the boundary between the wide part 411 and the narrow part 412. A cutout groove 4 with an arcuate cross section horizontally in the direction of
3 is formed. This groove 43 is set to be shallower than half the height of the joint material 4.

The tip of the narrow part 412 of the joint material 4 with this configuration is a joint surface 412b cut vertically in the up-down direction, and here there is a joint surface 42a formed in the same way at the end of the half-split material 42. is connected.

Here, in the joint material 4 and the half material 42, on the outer peripheral surface adjacent to the upper edge of the vertically divided surfaces 412a, 42a,
Grooves 412c, 42c in a U-shaped cross section along their upper edges.
is formed. Similarly, the lower edges of these vertically divided surfaces have L-shaped notches 412d, 42d.
is formed. These grooves and cutouts include
As shown in FIG. 1, a sealing member 7 for sealing off the space between the upper and lower wall members 4 is fitted.

This sealing member 7 includes a narrow plate 71 and an outer surface 7a.
The elastic layer 72 is made of an elastic material and is made of an elastic material.

Note that the wall material 5 that constitutes the other outer wall 3 has the same structure as the wall material 4 described above, except that the left and right sides are reversed, and corresponding parts have corresponding numbers. , and their explanation will be omitted.

The procedure for constructing the outer wall 2.3 using the wall material 4.5 having the above structure will be explained with reference to FIGS. 1, 3, and 4. First, a concrete cloth foundation 8 is placed at the location where the outer wall is to be installed, and a drainer 81 and a foundation 82 are installed on its upper surface. In addition, a square pillar 6 will be built at the corner of the outer wall. After this,
After installing the horizontally divided half-split material 9 on the side of the outer wall 2, on the other side of the outer wall 3, the wall material 5 is placed on the vertically split surface 5.
12a and 52a are attached to the outer surface of the base 82. Further, the semicircular end surface 511a of the wide portion 511 of the wall material 5 is set to be in contact with the surface 6a of the column 6. After this, the wall material 4 is similarly placed on the other outer wall side. As a result, the lower surface of the wall material 4 has the arc-shaped notch groove 53 of the wall material 5 disposed below it.
It will be in a state where it is exactly fitted. In this way, both the outer walls 2.3 are constructed by assembling the wall materials 4 and 5 in such a way that they are alternately orthogonal to each other.

Here, in this example, the depth of the notch grooves 43.53 is set to be shallower than half the height of the wide portion 411.511, so that the wall material 4 placed above and below and the wall material There is a gap between each number 5. A sealing member 7 is attached to each of these gaps. That is, grooves 412c, 512c and notches 412d, 512d are formed at the upper and lower ends of the wall material, respectively, into which the lower and upper ends of the sealing member 7 are fitted.

As a result, a rice cake cylinder-shaped outer wall 5 as shown in FIG. 4 is constructed.

In the outer wall 2.3 configured in this way, the small ends of the logs are exposed at the outer corner portions, as in the conventional log house, and the uneven surface of the logs is exposed on the outside. However, in the inner tsuba, the vertically divided surface 412a of the wall material 4.5,
42a, 512a, 52a and the inner surface of the sealing member 7 form a substantially flat surface. Furthermore, in this example, the sealing members 7 arranged between the wall materials 4 and between the wall materials 5 are not completely fixed to the wall materials as described above, and are capable of slight movement. At the same time, an elastic layer is formed on the surface side.

Therefore, even if the wall material 4.5 is distorted due to drying shrinkage or the like, such distortion can be absorbed by the minute movement of the sealing member 7 itself and the elastic deformation of its elastic layer. Therefore, it is possible to prevent gaps from forming in the outer wall 2.3 due to distortion of the wall material.

Next, FIG. 5 shows the wall material 4.5 of this example and a modified example of the wall structure using these materials.

In this modification, the depth of the arc-shaped notch grooves 43', 53' formed in the wall materials 4', 5' is set to exactly half the height of the wall materials. In this case, the upper and lower wall members 4' and the wall members 5' are assembled in contact with each other. In this case, it is preferable to connect the upper and lower parts using Yatoizane 1o.

Here, the joint material 41 (51) having the above structure is formed from a body, but as shown in FIG. It can also be constructed by joining them together. In this case, adhesive may be used to join the halves to each other,
Alternatively, filler wood may be used.

FIG. 7 shows a wall material according to another embodiment of the present invention and a wall structure constructed using the same.

The wall members 11, 12 of this example are the same as the wall members of the above embodiment except that their cross-sectional shape is rectangular. These wall materials 11, 12 are made up of vertically long square members, and are made up of joint members 11a, 12a at both ends thereof, and plate members 11b, 12b located between them. The joint members 11a and 12a formed at the tips have a vertically divided narrow portion 112.122, which is continuous with a wide portion 111.121 formed at the tip side.

The outer surfaces of these wall members 11.12 are flush, and the inner longitudinally divided surfaces 112a, 122a are perpendicular to the rectangular end surfaces 111a, 121a of the wide portions 111.121. The upper surface of the narrow portion 112.122 that is continuous with the wide portion 111.121 is cut into a rectangular shape to form a rectangular groove 113.123. The widths of these rectangular grooves are set to allow the wide portions 111 and 121 to fit therein. In addition, the upper surface 11 of the wide portion 111.121
1c and 121C have tenons 1lld and 121d extending in the material axis direction at the center in the width direction, and on the other hand,
The lower surfaces 111e and 121e have these tenons 111d,
Grooves 111f and 121f into which 121d can be fitted are formed. Similarly, the narrow portion 112, 122 and the plate 1
Tenons llc and 12c are also formed on the upper surfaces of 1b and 12b, and grooves lid and 12d into which these can be fitted are formed on the lower surfaces.

The wall members 11, 12 in this example are also assembled along the columns 13 in an alternating orthogonal manner. In the case of this example, Fig. 7 (
As shown in C), the rectangular end surfaces 111a and 12 of the wide portion
1a is attached to the pillar 13 at a position separated by the width dimension of the narrow part, and the narrow part of the wall material placed perpendicularly thereon is fitted into this gap. There is.

Figures 8 through 12 show exterior wall materials and wall structures using the same according to still other embodiments of the present invention.

First, FIG. 12 shows the end portion of the outer wall material 22.

As shown in the figure, the outer wall material 22 is composed of a joint material 221 and a plate material 222 to which the joint material is connected at both ends. The joint material 221 includes a wide part 223 with a trapezoidal cross section formed at the tip, a narrow intermediate plate 224 integrally formed following the wide part 223, and a notch 225a and a groove 225b for vertical connection. Joint plate 22 formed with
It consists of 5. The upper surface of the wide portion 223 is an inclined surface 223 formed such that the edge in the width direction is lowered.
It is said to be a. On the other hand, its lower surface is an inclined surface 223b that rises from the tip end toward the joint plate 225. Here, although these sloped surfaces 223a and 223b have a phase shift of 90 degrees in their slope directions, their slope angles are set to be the same. Therefore, the joint materials 221 of the exterior wall materials 22 that are in a vertical relationship can be combined with the ends of the exterior wall materials 22 crossed so as to be perpendicular to each other.

Next, the upper surface of the intermediate plate 224 is an inclined surface 224a that is continuous with the inclined surface 223a of the wide portion 223, and the lower surface thereof is also an inclined surface 224b that is continuous with the inclined surface 223b of the wide portion 223. There is. An upper upstanding surface of the joint plate 225 is continuous with the end of the upper inclined surface 224a of the intermediate plate 224, and this surface is used as a guide surface 225g. On the other hand, the end of the lower inclined surface 224b of the intermediate plate 224 abuts against the lower upright surface of the joint plate 225, and this surface is also used as a guide surface 225h.

Next, the tip of the joint plate 225 is a tangential plane 225C. This joint surface 225C is an inclined surface in order to increase the contact area with the plate material 222 to be connected. The notch 225a of the joint plate 225 and the groove 22 are also formed on the upper and lower end surfaces of the plate material 222 connected to the joint surface 225C of the joint plate 225.
A notch 222a and a groove 222b are formed which are continuous to the groove 5b. Further, a tangent plate 22 is provided on the end surface of the plate material 222.
A joint surface 222C is formed to be connected to the joint surface 225C of No.5.

Here, the length m of the inclined surface 224a of the intermediate plate 224 is set to be shorter than the width l of the wide portion 223.

Next, with reference to FIGS. 8 to 11, a procedure for assembling an outer wall surface using the outer wall material 22 having the above structure and the outer wall material 21 having a bilaterally symmetrical structure will be described.

First, as in the past, a foundation 31 and a drainer 32 are placed on a concrete cloth foundation 30, as is conventionally known.
etc. will be established. After that, the plate material 222 and the joint plate 225 of this outer wall material 22-1 are fixed to the base M130.
And the intermediate plate 224 is fixed in contact with the base 31.

Next, the wall material 21-1 is perpendicular to this outer wall material 22-1.
Place it at 1. When the inclined surfaces 213b and 214b of the outer wall material 21-1 are brought into contact with the inclined surfaces 223a and 224a of the outer wall material 22-1, they intersect with each other in the slope direction and are combined.

When assembled in this way, the wide part 21 of the outer wall material 21
3 is positioned in the lateral direction with its lower side hitting the guide surface 225g of the lower outer wall material 22 that is perpendicular to the guide surface 225g. Also,
The guide surface 215g of the outer wall material 21 hits the side surface 223C of the outer wall material 22, which is orthogonal to the lower side, and the material axis direction is positioned. That is, in this example, the thickness of the joint plate 225 is n
Then, since it is set to the relationship (f = m + n),
The guide surfaces 225h and 215h come into contact with the side surfaces 213c and 223c of the wide portion to be combined, respectively. In addition, each of the above dimensions is at least (f>m+
It is sufficient if the relationship is n).

On the other hand, when the outer wall materials 21.22 are assembled in this way, the wide part 2.13.223 and the intermediate plate 214.22
The corner portions 213d and 223d formed by 4 are positioned in contact with the pillar 36, respectively. Note that below the outer wall material 21-1, an auxiliary material 21', which is a part of the outer wall material, is placed on the foundation 30.

Here, outer wall materials 21 located above and below that form the same wall surface
A gap is formed between the outer wall materials 22 and between the outer wall materials 22, respectively. This gap is closed by a closing plate 28. Occlusion plate 2
8 has a structure in which a hard board 28a and an external vi 28b having some elasticity are stacked on top of each other. This occlusion plate 2
8, the upper edge is connected to the grooves 225b and 222 of the upper wall material 10.
b, and cut out the lower end edge 225a, 2
22a.

In this example configured in this way, when assembling the exterior wall materials, the orthogonal exterior wall materials are mutually guided, so the assembly work can be easily performed. In addition, sloped surfaces are formed on the top and bottom surfaces of the exterior wall material.
These sloped surfaces function as drainage surfaces, which is preferable because they can prevent rainwater from entering the room.

Next, FIG. 13 shows a modification of the outer wall materials 21 and 22 of this example. In this example, an inclined surface 72a is formed by cutting out the upper surface of the joint material 72 at the tip of the outer wall material 70 so as to become lower from one side edge in the width direction toward the opposite side edge. An upright wall 72 that stands up on the side of this inclined surface 72a
It is shaped like a g. Further, a sloped surface 72b is formed on the lower surface of the tip of the outer wall material 70 by cutting it upward from the tip in the longitudinal direction toward the rear end. Further, an upright surface 72h is formed which abuts on the tip of the inclined surface 72b. Note that the slopes 72a and 72b have the same slope.

This wall material 70 is used by specifying only the joint material 52 at the tip, and connecting an intermediate member of a predetermined length to the joint surface 72c of this joint material 72.

To assemble the exterior wall material 70 formed as described above,
This may be done in the same manner as for the exterior wall materials 21 and 22 described above.

〔Effect of the invention〕

As explained above, in the present invention, the wall joint material constituting the corner of the wall has a wide part that appears on the outside of the wall as a log or square timber, and a part that continues to this wide part is on the outside. The narrow part is flush with the wide part. Furthermore, the upper or lower surfaces of these wide and narrow portions are formed with cut-out portions into which the lower or upper surfaces of wall joint members of the same shape that are assembled across these wide and narrow portions can be fitted. Therefore, if the wall joint material of the present invention is used to construct the outer wall surface of a log house, etc., the tips of the logs or square timbers will be exposed at the outer corners and outer surfaces, and the uneven surface will appear due to them. , it is possible to obtain the same appearance as using thick logs or square timbers. Further, since the inner surface is formed as a flat surface, there is no problem of pressure on or narrowing of the inner chamber, and there is an advantage that it is easy to apply inner wall finishing materials such as cloth.
