Description

  The present invention relates to a log house assembly kit and a log house, and more particularly to an assembly kit and a log house suitable for a small log house.

  In recent years, full-scale log houses using logs and small log houses using processed timber are becoming widespread not only as resort buildings but also as general residential buildings or their ancillary buildings from nature-oriented or DIY-oriented.

  As shown in FIG. 7, a conventional log house using processed wood such as plate and square is generally composed of a base 51, a wall body 52, a roof 53, a floor, and the like (for example, JP-A-7-317177). No., JP-A-8-239923, JP-A-2002-54229, JP-A-2004-52478, etc.).

  The base 51 is configured by arranging four (two pairs) base members 54 having the same square cross-sectional shape substantially horizontally and assembling into a square. The wall body 52 is configured by using a plurality of rectangular plate-like wall body members 55 having fitting recesses in the vicinity of both ends and alternately stacking them on the base 51 in a cross-beam shape on each side. The roof 53 is composed of purlins, rafters, end walls, roof boards, and the like, and is attached on the wall body 52. The floor is composed of a plurality of flat plates and is laid on the base 51.

In the conventional log house, in the case of a relatively large log house, the wall body 52 is fixed to the base 51 with bolts and nuts as disclosed in Japanese Patent Application Laid-Open No. 2004-52478. On the other hand, in the case of a small log house of about 2 tatami to 8 tatami, the wall body 52 is simply placed on the base 51, or obliquely from the wall body member 55 to the base member 54 as shown in FIG. The nail 56 is fixed by driving.

  Although the conventional method of fixing the wall body 52 with bolts and nuts has a high fixing strength, the structure is complicated, resulting in difficulty in assembly and an increase in manufacturing cost. Further, this bolt and nut fixing method is difficult to apply to a small log house using a relatively thin wall member 55.

  On the other hand, when the log house receives a strong wind such as a typhoon, a force acts in the direction of overturning. However, the conventional fixing method of the wall body 52 by nail fastening is a fixing force against the force in the direction of overturning. Has the disadvantage of being very weak.

  Further, in the method of placing the wall body 52 on the base 51 as in the conventional log house, the positioning of the wall body 52 on the base 51 is not easy, and the outer surface of the base 51 and the wall body 52 is displaced. Will be cheaper. Such misalignment between the outer surface of the base 51 and the wall body 52 may cause rainwater or the like to accumulate, which may accelerate corrosion of the base 51 or the like.

  The present invention has been made in view of these disadvantages, and provides a log house assembly kit and a log house in which the base and the wall can be easily and reliably fixed and the wall can be easily positioned on the base. It is the purpose.

The invention made to solve the above problems is
Four prismatic base members that are arranged substantially horizontally and assembled into a square;
A plurality of rectangular plate-shaped wall members that are placed in a cross-beam shape on the assembled base member and are alternately stacked on each side to constitute a wall body,
A roof member attached to the upper part of the assembled wall member,
A log house assembly kit comprising a floor member laid on an assembled base member,
A log house assembly kit, wherein the base member is formed in an L-shaped cross section and has a rectangular wall mounting surface on an outer lower stage.

  In the log house assembly kit, since the base member is formed in an L-shaped cross section and has a rectangular wall mounting surface on the outer lower stage, positioning of the wall member on the base member is easy. And be sure. In addition, since the log house assembly kit places the wall body member on the terrace-like wall body mounting surface formed one step under the outside of the base member, the upper outer side of the base member assembled in a square shape It is surrounded and restrained by the wall members assembled together. For this reason, the log house assembly kit has essentially high engagement strength between the base on which the base member is assembled and the wall body on which the wall member is assembled, and further, fixtures such as nails, screw nails, and bolts are substantially horizontal. By driving into the wall member, the wall member and the base member can be firmly fixed.

In the log house assembly kit, the height (h ₁ ) of the pair of base members in the X direction and the height (h ₂ ) of the pair of base members in the Y direction The difference (h ₁ −h ₂ ) may be set to ½ of the vertical width (W) of the wall member. As described above, the difference (h ₁ −h ₂ ) between the height (h ₁ ) of the wall mounting surface in the X direction and the height (h ₂ ) of the wall mounting surface in the Y direction By setting the vertical width (W) to ½, the lowermost wall body member among the plurality of wall body members that are alternately stacked on each side to form the wall body has the same vertical width (W). It is possible to promote the unification of the constituent materials.

  In the log house assembly kit, the width (w) of the wall mounting surface may be equal to or less than the thickness (t) of the wall member. Thus, by setting the width (w) of the wall body mounting surface to be equal to or less than the thickness (t) of the wall body member, the flowability of rainwater or the like applied to the log house is promoted, and rainwater or the like is placed in the gap. Corrosion of the base member and the like due to staying can be suppressed.

  The base member in the Y direction has a protruding portion in the longitudinal direction on the rectangular wall body contact surface adjacent to the inside of the wall body mounting surface, and the wall body member placed on the base member in the Y direction is It is preferable to have a groove portion in the longitudinal direction on the inner side surface that abuts against the base member, and the protruding portion and the groove portion are fitted with the wall member placed on the base member. As described above, when the concave and convex fitting structure is provided between the wall contact surface of the base member in the Y direction (that is, the base member having the lower wall mounting surface) and the inner surface of the wall member, Even without using a fixture such as a wall member, the wall member can be easily and reliably connected to the base member in a state in which a plurality of wall members are stacked in a cross-beam shape and alternately on each side.

  On the other hand, the base member in the Y direction has a longitudinal groove on the rectangular wall body abutting surface adjacent to the inside of the wall body mounting surface, and the wall body member placed on the base member in the Y direction is A columnar locking member that has a groove in the longitudinal direction at a position facing the groove on the inner side surface that abuts the base member, and fits into both the grooves facing each other with the wall member placed on the base member May be provided. As described above, when the wall-contacting surface of the base member in the Y direction and the inner surface of the wall member have a groove portion that is opposed to each other and the columnar locking member that fits into both the opposite groove portions is provided, the nail Even without using a fixture such as a wall member, a plurality of wall members are stacked on the base member alternately in a grid pattern and alternately on each side, and the wall member is fitted in a state in which the engaging members are fitted in the opposing groove portions. It can be simply and reliably connected to the base member.

  The four base members may be joined by a concave / convex fitting structure. As described above, the log house assembly kit has a step on the outside of the base member, and the wall body member is assembled in a cross-girder shape in order to place the wall body member on the lower stage (wall body placement surface). In this state, the outside of the rectangular base member is restrained. Therefore, the base members are connected to each other and the assembled state can be maintained by simply assembling the four base members with a concavo-convex fitting structure.

  Therefore, the log house formed by assembling the log house assembly kit is difficult to assemble because the base and the wall can be easily and reliably fixed and the wall can be easily positioned on the base as described above. The strength can be improved without causing an increase in performance and cost. Therefore, the log house has a structure that can sufficiently withstand the force in the direction of overturning when receiving a strong wind such as a typhoon.

  Here, “outside” and “inside” mean directions corresponding to the outside and inside of the log house in the assembled state. “X direction” means any one direction on a horizontal plane. “Y direction” means a direction perpendicular to the X direction on a horizontal plane.

  As described above, the log house assembly kit and the log house of the present invention can improve the fixing strength between the base member and the wall member without causing difficulty in assembling and an increase in cost. In addition, the log house assembly kit and the log house can promote a reduction in manufacturing cost by unifying the constituent materials.

  The log house assembly kit of FIG. 1 mainly includes four base members 1, a plurality of wall members 2, a roof member (not shown), and a floor member (not shown). Yes. For example, natural wood, molded wood, woody synthetic material (using a synthetic resin or the like) or the like is used as a material for forming these constituent members.

  The four base members 1 are arranged substantially horizontally and are assembled in a square shape to constitute the base of the log house. The four base members 1 are prismatic bodies each having the same height and width, and a pair of base members 1a disposed in the X direction and a pair of base members 1b disposed in the Y direction. Consists of. The pair of base members 1b are arranged vertically so as to span the both ends of the pair of base members 1a.

The pair of base members 1a are formed in the same L-shaped cross section and have an elongated rectangular wall mounting surface 3a on the outer lower stage. The pair of base members 1b are also formed in the same L-shaped cross section, and have an elongated rectangular wall mounting surface 3b on the outside. The height (h ₁ ) of the wall body placement surface 3a of the base member 1a is different from the height (h ₂ ) of the wall body placement surface 3b of the base member 1b, and the wall body placement surface 3a. height (h ₁₎ than the wall height of the mounting face 3b (h ₂₎ is formed so as to be low (see Fig. 2). The width (w) of the wall mounting surface 3a of the base member 1a and the width (w) of the wall mounting surface 3b of the base member 1b are formed to be the same. In addition, the level | step difference is formed in the edge part of a pair of base member 1b so that the wall body mounting surface 3a continuous to a X direction with a pair of base member 1a may be comprised in the assembled state.

  The method for joining the four base members 1 is not particularly limited. For example, known means such as nail fastening, screw fastening, and fixing with bolts and nuts are employed.

The wall member 2b is longer than the base member 1b, and a recess 4b is formed in the upper and lower portions near both ends. The distance between the left and right recesses 4a of the wall member 2a is equal to the distance between the pair of wall mounting surfaces 3b of the pair of base members 1b in the assembled state, and the distance between the left and right recesses 4b of the wall member 2b is the assembled pair. It is equal to the space | interval of a pair of wall body mounting surface 3a of the base member 1a. The width (b) of the recess 4a and the recess 4b is formed to be approximately equal to the thickness (t) of the wall member 2 (slightly larger for ease of fitting), and the depth (d) is the vertical width of the wall member 2. It is formed to 1/4 of (W). Thereby, the wall member 2a in the X direction and the wall member 2b in the Y direction are assembled while being shifted by 1/2 of the vertical width (W).

The wall member 2b disposed at the lowermost portion in the Y direction has no lower concave portion 4b, and only a pair of upper and lower concave portions 4b are formed. The vertical width of the wall member 2b disposed at the lowest portion in the Y direction is such that the height (h ₁ ) of the wall mounting surface 3a in the X direction and the wall mounting surface 3b in the Y direction are described later. When the difference (h ₁ −h ₂ ) from the height (h ₂ ) of the wall member 2 is not ½ of the vertical width (W) of the wall member 2, adjustment is made according to the difference (h ₁ −h ₂ ). Is done. Further, the wall member 2b disposed at the uppermost portion in the Y direction has no upper concave portion 4b, and only a pair of concave portions 4b on both the left and right sides are formed.
