Description

  The present invention relates to a wall structure of a log house.

  As a structure of a wall set in a conventional log house, a plurality of wall members (log materials) obtained by sawing wood are alternately orthogonally stacked, and a plurality of wall members are stacked between two pillar members. A structure in which wall members are stacked is common. And regarding the former wall group structure, various members for wall (logging material) suitable for the structure are indicated (for example, refer to patent documents 1 and 2).

  On the other hand, with respect to the latter wall structure, for example, a plurality of column members each having a groove parallel to the longitudinal direction of the wood are formed at a predetermined interval on a flat surface formed by cutting the wood in the longitudinal direction. There is a structure in which a plurality of wall members each having a tenon formed on the facet surface are stacked between the column members while the tenons are inserted into the grooves of the column members. Furthermore, a groove similar to the groove formed in the pillar member is formed on the small edge surface of the wall member, and the wall member is stacked between the pillar members, and the groove of the pillar member and the groove of the wall member are formed. There is also disclosed a structure in which a pillar member and a wall member are joined by inserting a separate joining member into a space formed by the opposed grooves, and the like (for example, Patent Document 3). And 4).

  Also, with regard to the wall members stacked between the pillar members, log house timber (wall members) in which ridges are formed on the upper surface side along the longitudinal direction of the wall members and concave grooves are formed on the lower surface side. Etc. are disclosed (for example, see Patent Document 5).

JP-A-10-88704 (FIG. 3) JP-A-7-317177 (FIGS. 1 and 3) Japanese Patent Publication No. 2-5862 (FIGS. 1 to 4) Japanese Utility Model Publication No. 5-57120 (FIG. 1) JP-A-5-25868 (FIG. 1)

  However, in the structure in which multiple wall members (log materials) are alternately stacked and stacked in a cross beam, it is very difficult to process the wall members used, especially the intersection, and it takes time. As the log house construction cost increases.

  Moreover, also in the aspect which piles up the member for walls between pillar members, formation of the tenon or protruding item | line to a member for walls, or the joining member which has the complicated shape indicated by patent documents 3, 4 and the said joining member are inserted. Since the formation of a possible groove takes time for processing work, the construction cost becomes high as described above.

  Furthermore, there is a possibility that rainwater may invade between the stacked wall members. If the wall members disclosed in Patent Documents 2 to 5 are applied, the rainwater that has entered between the wall members reaches the inside of the log house. Hard to reach. However, as described above, since any of the wall members disclosed in these patent documents takes time for processing work, the construction cost increases.

  Furthermore, from the viewpoint of effective use of resources and control of construction costs, thinning materials are being actively used for log house construction. Thinned wood has variations in shape and dimensions, and material costs can be reduced compared to general building materials. As a result, construction costs of log houses can be reduced. However, even if thinned wood is used, if the above-described complicated processing operation is performed, the lumbering cost increases, and as a result, the construction cost cannot be suppressed.

  Furthermore, there is a risk of deformation and cracks due to drying shrinkage in wood, but thinning materials are particularly prone to deformation due to drying shrinkage. It was one of the important issues.

  In view of the above problems, the present inventor intends to effectively use the thinned wood, and can easily construct the wall of the log house without subjecting the thinned wood to complicated lumbering. As a result of intensive studies to provide the above, the present invention has been achieved.

  That is, the gist of the wall structure of the present invention is that a flat portion formed by cutting wood in the longitudinal direction is formed, and a guide groove parallel to the longitudinal direction of the wood is formed in the flat portion. A pillar member, and an upper surface and a lower surface formed by cutting the wood in the longitudinal direction, water passages parallel to the longitudinal direction of the wood being formed on the upper surface, and forks at both ends in the longitudinal direction of the wood A wall member having an insertion hole formed on the surface thereof, and a thick plate inserted into the insertion hole, and the two column members are erected with the guide grooves facing each other. The plurality of wall members in which the thick bars are inserted into the insertion holes are stacked between the two pillar members while the thick bars are inserted into the guide grooves.

  In the wall assembly structure, the bottom portion of the water flow groove may be inclined from one of the small edge surfaces toward the other of the small edge surfaces.

  Further, in such a wall assembly, the wall member is formed with a through-hole penetrating the upper surface and the lower surface, and a through bolt is inserted into each through-hole of the plurality of stacked wall members. The plurality of wall members are preferably joined by screwing nuts.

  According to the wall assembly structure of the present invention, a log house wall can be easily constructed by simply stacking a plurality of wall members between a plurality of pillar members. In particular, the column member and the wall member according to the present invention are very easy to lumber, and therefore can reduce the lumber cost. In addition, by using thinned wood as wood, it is possible to reduce material costs, and as a result, log house construction costs can be reduced.

  Moreover, since the water flow groove is formed in the upper surface in the wall member according to the present invention, when rain water enters between the stacked wall members, the rain water is passed through the water flow groove to the column member. Water can be introduced into the guide groove. That is, rainwater that has entered between the wall members is actively guided into the water passage groove, so that rainwater can be prevented from entering the inside of the log house from the water passage groove.

  Furthermore, the water flow groove has a function of draining rainwater that has entered between the wall members to the outside of the log house, and has an effect of suppressing deformation and cracks generated in the wall members. In wood, deformation and cracking due to drying shrinkage occurred, especially in thinned wood, the occurrence of such deformation and cracking was a particular problem, but by forming a water flow groove in the wall member in advance, Actively use thinned wood that can absorb deformation and cracks generated in the wall member by the water flow groove to suppress the deformation and cracking of the wall member and reduce the material cost. Is possible.

  Furthermore, by inclining the bottom of the water flow groove, rainwater that has flowed into the water flow groove can be more actively guided to the guide groove of the column member. Can be performed more efficiently.

  Further, in the wall structure of the present invention, the strength of the wall itself is improved and the strength of the log house itself is improved by joining the plurality of stacked wall members with through bolts and nuts.

  Hereinafter, embodiments of the wall structure of the present invention will be described with reference to the drawings. The wall assembly structure 10 according to the present embodiment shown in FIGS. 1 and 2 is mainly composed of pillar members 12 and 12a and a wall member 14. FIG. 1 is a perspective view seen from the direction of arrow A in FIG. 2, and the symbol S means the inside of the log house. As shown in FIGS. 3A to 3C, the column member 12 has two plane portions 16 formed by cutting the wood 11 such as thinned wood in the longitudinal direction thereof. The plane portions 16 and 16 are perpendicular to each other. Each of the flat portions 16 and 16 is formed with a guide groove 18 parallel to the longitudinal direction of the wood 11. Moreover, the column member 12a shown to FIG.3 (d)-(f) is other embodiment of the column member 12, and is a column member which can be used when constructing | assembling a wall with a wide frontage. Two plane portions 16 are also formed on the column member 12a. The two plane portions 16 and 16 are parallel to each other. In addition, the guide grooves 18 are formed in the two plane portions 16 and 16 as well as the column member 12.

  Note that a pin insertion opening 24 for pin-joining the column members 12 and 12a and the beam member 13 (see FIG. 5) is formed on the upper end surface 20 when the column members 12 and 12a are erected. The lower end surface 22 is formed with a pin insertion opening 24 for pin joining to the base 26.

  On the other hand, as shown in FIGS. 4A to 4C, the wall member 14 has an upper surface 30 and a lower surface 32 formed by cutting the wood 11 such as thinned wood in the longitudinal direction. The upper surface 30 and the lower surface 32 are parallel to each other. A water flow groove 34 parallel to the longitudinal direction of the wood 11 is formed on the upper surface 30. Furthermore, insertion holes 38 for inserting later-described thick bars 40 (see FIG. 5) are formed on both ends of the wood 11 in the longitudinal direction, that is, on the small edge surfaces 36 and 36 on both ends of the wall member 14.

  In the wall structure 10 of this embodiment, first, a plurality of column members 12 and 12a are erected on a base 26 with a predetermined interval (see FIGS. 2 and 5). At this time, the adjacent column members 12 and the column members 12 and the column members 12a are erected in a state where the guide grooves 18 formed in the respective plane portions 16 are opposed to each other. In the present embodiment, the column members 12 and 12a are erected on the base 26 by using the pin 27 formed on the base 26 and the pin insertion opening formed on the lower end surface 22 of the column members 12 and 12a. Although it joins by inserting in 24, the standing method of the column members 12 and 12a is not specifically limited, All the known standing methods are applicable.

  Next, the thick bar 40 is inserted into the insertion hole 38 formed in the small face 36 of the wall member 14. As shown in FIG. 5, the plurality of wall members 14, 14,... Into which the thick bars 40 are inserted are wall members with the upper surface 30 on which the water flow grooves 34 are formed facing upward. The wall W is constructed by being stacked between the column members 12 and 12 and between the column members 12 and 12a. When the plurality of wall members 14, 14,... Are stacked, the thick members 40 are stacked while being inserted into the guide grooves 18 of the column members 12, 12a, so that a plurality of the column members 12, 12a are stacked. The wall members 14, 14,... Are joined.

  As described above, according to the wall assembly structure 10 of the present embodiment, it is possible to easily construct the log house wall W only by stacking the plurality of wall members 14 between the plurality of column members 12 and 12a. it can. In particular, since the pillar members 12 and 12a and the wall member 14 according to the present embodiment are very easy to lumber, the lumber cost can be suppressed. In addition, by using thinned wood as wood, it is possible to reduce material costs, and as a result, log house construction costs can be reduced.

  Moreover, since the water flow groove 34 is formed in the upper surface 30 side in the wall member 14 which concerns on this embodiment, rainwater exists between each member of the stacked wall members 14,14, .... When entering, this rainwater can be introduced into the guide groove 18 of the column member 12 through the water flow groove 34. That is, rainwater that has entered between the wall members 14 and 14 is actively guided into the water flow groove 34 and is prevented from entering the inside S of the log house from the water flow groove 34. The rainwater that has flowed downward in the guide groove 18 of the column member 12 is drained to the outside of the log house through a water guide path 28 that is provided in advance in the base 26 and communicates with the guide groove 18. Rainwater does not collect in the groove 18.

  Furthermore, the water flow groove 34 has a function of draining rainwater that has entered between the wall members 14 and 14 to the outside of the log house as described above, and has an effect of suppressing deformation and cracks generated in the wall member 14. is there. In wood, deformation and cracking due to drying shrinkage occur, and particularly in thinned wood, the occurrence of deformation and cracking has been a particular problem. However, a water flow groove 34 is formed in the wall member 14 in advance. Therefore, the water flow groove 34 can absorb deformation and cracks generated in the wall member 14, and can suppress deformation and cracks to the wall member 14. Can be used.

  As mentioned above, although the wall structure 10 which concerns on embodiment of this invention was explained in full detail, embodiment of this invention is not limited to said form. For example, in the wall assembly structure 10a shown in FIG. 6, the plurality of wall members 14a constituting the wall assembly structure 10a have through holes 42 penetrating the upper surface 30 and the lower surface 32 of the wall member 14a. When the members 14a are stacked, the through holes 42 formed in the upper wall member 14a and the through holes 42 formed in the lower wall member 14a are linearly arranged.

  When stacking a plurality of wall members 14a between the column members 12 and 12a, the thick plate 40 is inserted into the guide groove 18 associated with the column members 12 and 12a as in the case of the wall assembly structure 10, and the base 26 is previously provided. A through bolt 44 erected on the through hole 42 is inserted into the through hole 42. Then, among the plurality of stacked wall members 14a, a plurality of wall members 14a are screwed into the tip ends of through bolts 44 protruding from the through holes 42 of the uppermost wall member 14a. Will be firmly joined. That is, according to the wall structure 10a according to the present embodiment, the strength of the wall W is improved, so that the strength of the entire log house can be improved.

  In the wall assembly 10a shown in FIG. 6, the above-described through-holes are provided on the lower surface side of the beam member 13 joined to the column members 12 and 12a, that is, on the surface side opposite to the upper surface 30 of the uppermost wall member 14a. The front end of the bolt 44 and a recess 48 that can accommodate the nut 46 are provided. For example, a through-hole through which the bolt 44 can be inserted is also provided in the beam member 13 and protrudes to the upper surface side of the beam member 13. A structure in which the base 26, the plurality of wall members 14 a, and the beam member 13 are integrally joined by screwing a nut 46 to the tip of the through bolt 44 may be employed.

  Further, the number of through holes 42 formed in the wall member 14a is not particularly limited, and can be arbitrarily set according to the distance between the column members (frontage), the height of the wall W, and the like. Further, as shown in FIG. 6, the position where the through hole 42 is formed may be formed in the central portion in the direction perpendicular to the longitudinal direction of the wall member 14a, that is, in the water passage groove 34, or in the water passage. You may form in the position shifted from the groove | channel 34 right and left. In particular, by forming the through hole 42 in the water groove 34, the rainwater that has entered between the stacked wall members 14 a is logged through the guide groove 18 of the column member 12, as in the wall structure 10. The water can be drained to the outside of the house and can also be drained through the through hole 42. In addition, in order to drain rainwater to the outside of the log house through the through hole 42, it is necessary to previously form a water guide path 28 a communicating with the through hole 42 in the base 26. By forming the water guide path 28a, the rain water flowing down through the through hole 42 can be drained outside the log house without being stored in the through hole 42.

  The wall structure according to the embodiment of the present invention exemplified above should not be construed as substantially limiting the technical idea of the present invention. For example, in the wall assembly structure 10, 10a according to the embodiment shown in FIGS. 5 and 6, the water flow grooves 34 are provided in parallel to the upper surface 30 and the lower surface 32 of the wall members 14, 14a. Like the water flow groove 34a related to the wall member 14b shown in FIG. 7A, the bottom 35 of the water flow groove 34a is directed from one small edge surface 36a of the wall member 14b to the other small edge surface 36b. It may be inclined. By inclining the bottom 35 of the water flow groove 34a, rainwater that has flowed into the water flow groove 34a can be actively introduced to the guide groove 18 of the column member 12, and the drainage efficiency of rainwater can be improved. .

  FIG. 7B is also a side view showing another embodiment of the wall member according to the present invention. As shown in the wall member 14c shown in FIG. The upper surface 30a may be recessed so that the position of the upper opening is the lowest, and the lower surface side may be a lower surface 32a that protrudes downward so as to be fitted to the upper surface 30a. By applying the wall member 14c formed with the upper surface 30a and the lower surface 32a to the wall assembly structure of the present invention, the rainwater that has entered between the stacked wall members 14c is actively guided to the water flow groove 34. In addition, it is possible to more reliably prevent rainwater from entering the interior S side of the log house. Furthermore, when stacking the wall member 14c, the lower surface 32b side of the upper wall member 14c is fitted into the recess on the upper surface 30a side of the lower wall member 14c, so that the strength of the wall member 14c is increased. Can be improved. When the wall member 14c is applied to the wall assembly structure of the present invention, the lower surface of the wall member placed immediately above the base 26 is preferably a flat surface, like the lower surface 32 of the wall member 14. (Wall member 14d) The upper surface of the wall member that is positioned immediately below the beam member 13 is preferably a flat surface (wall member 14e), like the upper surface 30 of the wall member 14.

  Moreover, in the column member 12a shown in FIGS. 2 to 4, the two parallel plane portions 16 are formed, but a plane portion 16 a orthogonal to the two parallel plane portions 16 may be formed. That is, in the column member 12a shown in each drawing, the protruding portion of the column member 12a toward the inside S side of the log house can be eliminated by cutting the wavy line portion to form the plane portion 16a.

  FIG. 8 is a plan view showing another embodiment of the column member according to the present invention. As shown in the column member 12b shown in FIG. 8A, the angle formed by the two plane portions 16 is an acute angle. May be formed. By applying the column member 12b to the wall structure of the present invention, the shape of the log house is not limited to a log house having a rectangular shape or a combination of rectangles. Is also possible. Further, as shown in FIG. 5B, according to the pillar member 12c having the three plane portions 16 and the adjacent plane portions 16 each having a right angle, the wall W of the log house is formed in a T shape. Can be built.

  Further, in the wall members 14 and 14a and the like, it is preferable to form only the upper surface 30 and the lower surface 32 which are parallel from the viewpoint of suppressing the sawing cost, for example, the curved surface portion facing the inside S side of the log house, for example. 15 may be cut to form a plane portion orthogonal to the upper surface 30 and the lower surface 32. By forming the flat portion on the wall member 14 or the like, the wall surface on the inside S side of the log house becomes flat, so that the attaching operation of the wall panel or the like becomes easy.

  Although the wall frame structure of the present invention has been described in detail above, the wall frame structure of the present invention can be applied to construct a wall of a relatively large building such as a log house, as well as a relatively small shed, storeroom. The present invention can be applied to the construction of a wall relating to a building such as a wall, or a wall relating to a small building such as a kennel. The present invention can be carried out without departing from the gist thereof, with appropriate improvements, changes or additions based on the inventive ideas and ideas of those skilled in the art.
