Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a log house having a main wall formed by combining a log or a half log (hereinafter simply referred to as wood), and a mounting structure for wood.

<Conventional technology> As a technology related to a log house or a wood mounting structure constituted by combining this kind of wood, Japanese Utility Model Application Laid-Open No.
As disclosed in Japanese Patent No. 4818, a technique for forming a panel unit by bonding the logs or semi-logs to each other at a slight angle with respect to a horizontal plane, thereby forming a wall surface, Japanese Utility Model Application Publication No. 60-179717. As disclosed in Japanese Unexamined Patent Publication (Kokai) No. H10-26, a technique in which a joint material is embedded between logs stacked so that each flat surface is superimposed, or as disclosed in Japanese Utility Model Application Laid-Open No. 61-26808, 2. Description of the Related Art A technique is known in which a ridge or a concave ridge into which the ridge can be fitted is provided, and a log material is sequentially laminated by combining these.

<Problems to be Solved by the Invention> However, the first technique is to prevent the rainwater from entering the bonding surface by bonding a bonding surface such as a log material at a small angle to a horizontal surface. Although there is an effect that it can be prevented, it is difficult to form a panel unit by stacking log materials or the like that are not well seated with a certain inclination angle with high accuracy, and there are problems such as poor workability. The second and third techniques aim at completely sealing the flat surfaces of the logs to be joined, respectively. However, processing and assembling the logs is troublesome for complete sealing, and the cost is low. There were problems such as high prices. Further, there is room for improvement in practical points including mounting in any of the techniques.

The log house and the wood mounting structure according to the present invention relate to a completely new technology developed in view of the above conventional points.

<Means for Solving the Problems> The first invention of the present invention relates to a method for manufacturing a plurality of timbers having flat upper and lower surfaces and projecting fitting protrusions having inclined surfaces at both axial ends at both axial ends. A log house characterized in that a fitting projection is fitted into a groove of a steel material of a skeleton, and a plurality of woods are sequentially inclined and laminated between the skeletons to form a main wall surface.

Further, the second invention of the present invention is characterized in that the fitting projection of the wood, which is provided with a fitting projection having an inclined angle on both sides at both ends in the axial direction, is fitted into a groove of a vertically erected steel material, and a flat surface of the wood is formed. This is a wood mounting structure characterized in that it is mounted at an angle.

<Operation> The first invention is characterized in that a plurality of lugs, each having flat surfaces on upper and lower surfaces and protruding at both ends in the axial direction and having both sides inclined at an angle, are used as a steel material for a frame. In the groove of the above, a plurality of woods are tilted in order and stacked between the frames, thereby forming the main wall surface, so that the joining surface of each wood can be easily tilted outward, thereby Intrusion of rainwater, wind, etc. can be prevented.

According to a second aspect of the present invention, the wood is provided on both ends in the axial direction with projections having an inclined angle on both sides, and is inserted into a groove of a steel material which is vertically erected. Lamination can be performed while keeping a fixed inclination angle and making close contact with each other, and the wall surface made of wood can be surely configured.

<Example> An example of a log house and a wood mounting structure according to the present invention will be specifically described with reference to the drawings as follows.

The structure of the wall of the log house of the present invention and the mounting structure of wood will be described with reference to the drawings. In FIGS. 1 to 3, reference numeral 1 denotes a log material, and upper and lower surfaces thereof have flat surfaces 1a and 1a.
b is provided respectively. A rectangular fitting projection 3 having a width substantially equal to the inner diameter of the groove 22 which can be fitted into the groove 22 of the C-shaped channel material 2b is formed at both ends of the log material 1 in the longitudinal direction thereof.
It is protruded with a length almost equal to the depth. The upright surfaces 3a, 3b on both sides of the fitting projection 3 are flat surfaces 1 of the log material 1.
It is composed of a plane having an inclination angle α of 10 to 40 degrees with respect to a vertical plane perpendicular to a and 1b. The flat surface 1a, 1 of the log 1
A groove 4 is formed in b in the longitudinal direction, and a joint member 5 can be fitted into the groove 4.

Regarding the assembling structure of the wall surface of the log house and the mounting structure of the wood according to the present invention, as shown in FIGS.
The channel material 2b and the H-shaped steel 2c attached to the prism 2a are vertically erected at predetermined intervals, respectively, and the fitting protrusion 3 of the log 1 is inserted into the groove 22 of the channel material 2b or the H-shaped steel 2c. By laminating the flat surfaces 1a, 1b of each log 1 in close contact with each other, the log materials 1 are stacked such that the flat surfaces 1a, 1b of each log 1 are always inclined outward at the predetermined angle with respect to the horizontal plane. Are automatically laminated in order to form a wall surface, and the main wall surface of the log house as shown in FIGS. 6 and 7 can be assembled.

Further, a joint member 5 can be attached between the respective log materials 1 by using the groove 4 as shown in the figure, if necessary.

Further, as shown in FIG. 4, the center of each log 1 can be skewed by a reinforcing bar 7 standing upright from the foundation beam 6, and this can be fixed by a nut 8 or the like. Further, as shown in FIG. 5, it is also possible to attach a bumpy decorative material 10 to the side surface of the H-shaped steel 2c with bolts 9 to decorate this portion.

In the above embodiment, the inclination angle of the flat surfaces 1a and 1b of the log 1 with respect to the horizontal plane is 10 to 40 degrees, particularly 20 to 30 degrees, which is efficient against rainwater intrusion.

<Effect of the Invention> As described above, the log house and the wood mounting structure according to the present invention are provided with protrusions that can be fitted into the grooves of the steel material, for example, the H-shaped steel or the channel material at both ends in the axial direction of the wood. By fitting the portion into the groove, a large number of woods can be sequentially laminated to form the main wall surface of the log house, thereby greatly simplifying the construction work, and the upright surfaces on both sides of the projecting portion can be formed. Since it was inclined at a predetermined angle with respect to the vertical surface, when the protrusions were fitted into the grooves and each piece of wood was laminated, the flat surface of each piece of wood was always automatically inclined at a constant angle with high accuracy, Thus, it is possible to positively prevent rainwater, wind, and the like from entering from the contact surface of each piece of wood, and the whole structure is simple so that mass production can be performed at low cost. .
