[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a wall plate manufactured by processing a thick plate material such as a cedar scaffold plate material, and a house having a wall formed by the wall plate.

[0002]

[Prior art]

 In a conventional wooden house, the wooden wall has a double-walled structure consisting of an outer wall and an inner wall that are formed by laminating thin wall plates on the outside and inside, respectively.The outer wall prevents rainwater from entering, The seam ends are overlapped or covered with a patch to cover the seam. In log houses, logs are processed and walls are formed vertically.

[0003]

[Problems to be solved by the invention]

 In such a conventional wooden house, it is necessary to construct a double-walled thin wall plate inside and outside, and also to prevent rainwater from entering. Therefore, many days are required for construction, and construction costs are increased. There was a problem that becomes high. In addition, since a thin plate is used for the wall material, it lacks strength and durability and is weak against typhoons. Furthermore, in the case of a double-walled structure consisting of an outer wall and an inner wall, there is a drawback that the ventilation between the walls is poor and the corrosiveness tends to occur. There is also a disadvantage that it easily occurs. On the other hand, in log houses, since logs are processed and assembled vertically, processing is difficult, workability is low, and material costs are high, so construction costs are necessarily high and there is a problem. In addition, there has been a problem that the cost of timber construction has become higher because timber for construction has risen in recent years due to the depletion of timber resources.

Accordingly, the present invention solves the above-mentioned problems of the prior art, and has a low production cost, a wall plate excellent in strength and durability, and a building that can be constructed using the wall plate in a short construction period. It is an object of the present invention to provide a house that is inexpensive, hardly generates white light, and has excellent strength and durability.

[Means for Solving the Problems]

 The present inventor focused on the fact that scaffolds made of cedar planks can be obtained relatively inexpensively, and studied how to use them. As a result, the inventors came up with the idea of using them as wall materials, and came to the present invention. In other words, the wall plate of the present invention that achieves the above object is composed of an engaging hook and an engaging groove adjacent to the inside of the engaging hook in the width direction at both ends in the width direction of a thick plate such as a cedar scaffold plate. It is characterized in that it is manufactured by forming a pair of connecting portions having a hook-like cross section over the entire length in the longitudinal direction. The thick plate material is not limited to the cedar scaffold plate, and any thick plate material with a thickness of about 20 to 30 mm may be used. However, lumber manufactured according to the scaffold plate standard is less expensive than ordinary built plate materials. desirable.

The pair of connecting portions are formed such that the opening directions of the respective engaging grooves are formed opposite to each other with respect to the plate thickness direction, and when the wall plates having the same shape are arranged adjacent to each other in the width direction. The engaging hooks and the engaging grooves of these wall plates are engaged with each other, and adjacent wall plates are aligned and connected in the thickness direction.

In the wall plate, of the rising surfaces on both sides of the engaging groove of each connecting portion, the rising surface on the inner side in the width direction of the wall plate is in a convex arc shape in cross section with the side surface of the wall plate on the opening side of the engaging groove. And the back surface of the engaging hook portion adjacent to the engaging groove has a convex arcuate cross-section that smoothly continues to the wall plate side opposite to the engaging groove opening side. It is desirable to be formed by the curved surface.

In the house of the present invention, a plurality of wall plates having the above-described configuration are stacked in the vertical direction, and the connecting portions are connected to each other and fixed to a pillar, thereby providing a thick and strong wall structure. Since it can be formed, there is no need to separately provide an inner wall, and a closed space is not formed between the walls as in the past, so that termites are less likely to be generated and the waterproofness is excellent, and a log house style utilizing natural wood is used. It is excellent in aesthetics and can be formed at low cost.

[Embodiment of the invention]

 The wallboard of the present invention is suitable mainly for houses such as wooden houses, and can also be used as a wall material for bungalows and storage houses for other uses. It is produced. The cedar scaffold plate is inexpensive, thick and durable, and has a constant size and a flat rectangular cross-section. be able to. Also, most scaffolding boards are made of cedar wood, so that both sides can be finished smoothly with canna, etc., to create a wall board that makes use of the beautiful grain of Japanese cedar.

In order to manufacture a wall plate from a scaffold plate material, the scaffold plate material is cut into a predetermined length, connection portions are formed at both ends in the width direction, and a plurality of wall plates are mutually connected by these connection portions. Be able to connect. The connecting portion formed by processing both ends in the width direction of the scaffold plate material is formed in a cross-sectional hook shape including an engaging hook portion and an engaging groove, and the manufactured wall plates are arranged in the width direction. At this time, the engaging hook portions and the engaging grooves of these wall plates are engaged with each other, and the adjacent wall plates can be aligned in the plate thickness direction and connected in the same plane.

[0011] With this connection structure, a plurality of wall boards can be stacked one on top of the other, and each wall board can be fixed to a pillar of a house with a fixing member such as a nail to form a wall. At this time, the width direction of the wall plate is oriented in the vertical direction, the opening of the engaging groove of the upper connecting portion is directed to the outside of the house, and the opening of the engaging groove of the lower connecting portion is directed to the inside. With this arrangement, the rainwater that hits the outer surface of the wallboard quickly flows down the wallboard surface and prevents rainwater from directly entering the inside of the wallboard.

Further, of the rising surfaces on both sides of the engaging groove of each connecting portion, the rising surface on the inner side in the width direction of the wall plate intersects with the side surface of the wall plate on the opening side of the engaging groove through a curved surface having a convex cross-sectional arc. The back surface of the engaging hook portion that is smoothly continuous and adjacent to the engaging groove is formed by a curved surface having a convex cross-sectional arc shape that is smoothly continuous with the side of the wall plate opposite to the engaging groove opening side. In this case, rainwater is guided to these curved surfaces and is eliminated to the outside from the gap between the engaging hooks that engage with each other, and the infiltration of rainwater into the wallboard is more effective. Rainwater does not remain in the joints, and no corrosion occurs due to rainwater infiltration or remaining in the joints for many years.

[0013] Furthermore, by filling a waterproof caulking material between the engagement groove of one wall plate and the engagement hook of the other wall plate to be engaged with the engagement groove to close the gap, the outdoor part of the house is provided. Infiltration of rainwater from inside the room is more reliably prevented. Further, a waterproof paint or a preservative may be applied to the outer surface of the wallboard.

Further, the corner portion where the two wall surfaces of the house intersect at a right angle is a longitudinal end surface of a wall plate constituting one wall surface, and a longitudinal inner end portion of a wall plate constituting a wall surface perpendicular to the corner wall. The longitudinal end faces of the two side walls facing each other or facing each other at right angles should be chamfered, for example, at an angle of 45 degrees, so that they face the outside of these corners. Is covered with an L-shaped cover member oriented vertically, thereby preventing infiltration of rainwater into the corner portion from the end face in the longitudinal direction of the wall plate.
