Description

  The present invention relates to a log house with good construction efficiency and excellent durability.

  Conventionally, a log house is provided with a circular notch notch part matching the cross-sectional shape of the intersecting log material on the lower surface of the log material to make a log material, and the log material intersects with no gap while keeping the notch part up and down Were stacked like so. With this configuration, rainwater from the upper part is formed so as to flow down the surface of the wall body, thereby preventing rainwater from entering between the log members.

  However, in such a conventional log house, it is difficult to position the intersecting log materials, and efficient construction cannot be achieved. Therefore, as shown in FIG. 4, the end portion of the log member 11 is notched from the top and bottom and from the left and right so that the crossing portion can be easily positioned, and the core portion that is cut out is parallel to the top and bottom surfaces and the left and right surfaces, respectively. A square notch portion 13 formed so as to become, a notch 19 is provided at an angle of about 45 degrees in the longitudinal direction of the log material from both ends of both side surfaces of the core portion, and positioning can be performed by the square notch portion 13; By providing the cutouts 19, the log members 11 that overlap vertically are made to adhere to each other. However, with this configuration, the central portion of the cutout portion 19 provided at an angle of about 45 degrees is to be exposed on the wall surface.

  As a technology to eliminate this drawback, the log is made of log material, and the core is formed so that the upper and lower surfaces and the left and right surfaces are parallel to each other, and the log material is flush with the side surface of the core. There is disclosed a log material joint structure having a concave curved surface portion provided so as to fit a curved surface on a side surface of a log material which is provided with a notch toward the upper end and overlaps with each other.

Are formed so as to be parallel to each other, and the round notch portion is notched so as to be widened toward the lower end of the log material so as to be flush with the side surface of the square notch portion, The log house is characterized in that the side surfaces forming the convex curved surface of the log material intersecting and overlapping with each other are fitted.

  Further, in the log house according to (2) above, the square notch portion is formed by cutting a quarter of the log material above and below the log material, and the round notch portion Is a log house characterized in that half of the log material is cut out along the convex curved surface of the side surface of the log material stacked under the log material.

  That is, according to the present invention, there is provided a log house in which a notch portion of the log material is not exposed in the notch portion, and rain water traveling through the wall portion can be effectively allowed to flow down on the outer surface of the outer wall. Can do.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a log house of the present invention, FIG. 2 is a perspective view showing a configuration of a wall of the log house of the present invention, and FIG. 3 is a front view of a log material used for the log house of the present invention. FIG. 4 is a perspective view showing a configuration of a wall body of a conventional log house.

As shown in FIGS. 1 and 2, the log house 1 includes a plurality of log members 11 extending in the horizontal direction, stacked in the height direction to form an outer wall portion 2, and at an intersection of two outer wall portions 2 and 2. The log members 11 are overlapped with each other in an intersecting state. Further, the end portions of the log material 11 protrude outward from the surface of the outer wall portion 2 on the other side.
In the vicinity of the end portion of the log member 11, a notch 12 that is a recess formed by cutting out a portion in the vicinity of the end portion is provided, and the two outer wall portions 2 intersecting each other by fitting the notches 12 together. 2 are closely attached to each other.

  As shown in FIG. 2, the log member 11 has convex curved surfaces on both sides, and the notch 12 is cut out from the top and bottom and from the left and right to form a square notch portion 13 and a round notch portion 14. Yes. The square notch portion 13 is formed such that the cut-out core portion is parallel to the upper and lower surfaces and the left and right surfaces. In addition, the round notch portion 14 is cut out so as to be widened toward the lower end of the log material 11 so as to be flush with the side surface of the square notch portion 13, 11 side surfaces forming a convex curved surface are fitted.

  By forming in this way, the notch portion and the square notch portion 13 of ¼ each are fitted in the upper and lower sides, so that the positioning of the intersecting portion of the upper and lower log members 11 is facilitated, and the construction work time is shortened. be able to. Moreover, since the round notch part 14 is notched in the shape according to the convex curved surface of the lower log | logging material 11, rainwater flows down smoothly along the convex curved surface of the lower | lower log material 11, and may stay.
