Description

  The present invention relates to a wooden structure, and more particularly to a wooden structure having a wall surface on which wall materials are stacked.

  Wall materials are stacked in wooden structures such as log houses and wooden houses, wooden indoor equipment such as counters and partitions, wooden outdoor equipment such as playground equipment and fences, or various wooden structures such as wooden furniture. Some of them have wall surfaces. And in such a wooden structure, it is generally made to obtain a solid texture of the wall surface by using solid wood as the wall material. In order to reduce the weight and the like, it has been devised to use an assembled wood in which a plurality of wooden members are integrated so that a hollow portion is formed inside as a wall material.

Japanese Patent Laid-Open No. 11-287016

  However, if the wall surface is simply formed by stacking wall materials made of assembled wood, the joining lines of the wooden members constituting the assembled wood are exposed on the wall surface, and the heavy wall texture is given. It will decrease. In particular, in wooden buildings such as log houses, the outer wall surface is exposed to wind and rain, so if the joint line between wooden members is exposed on this outer wall surface, rainwater enters the joint line and the joint line is darkened. , Not only the heavy texture is deteriorated, but also the beauty of the wall surface is impaired.

  The present invention has been made in view of the above-mentioned actual situation, and even when an assembly wood is used as a wall material, a wooden material that can obtain a heavy texture similar to that using solid wood as a wall texture. The issue is to provide a structure.

The main means for solving the above problems are:
“A wall material made of assembled wood in which a plurality of wooden members are integrated so that a hollow portion is formed inside,
A wooden structure comprising: a plurality of wall members stacked on the upper surface and the lower surface, the surfaces of which the bonding lines between the plurality of wooden members are exposed. ''
It is.

  Here, the structure of the assembled wood in which a plurality of wooden members are integrated is not particularly limited, and there are a plurality of appropriate methods such as mutual locking, adhesive bonding, bolting and fixing with nails, and the like. What is necessary is just to integrate these wooden members.

  In the wooden structure configured as described above, the joining line between the wooden members constituting the wall material is not exposed to the wall surface. Therefore, even when assembled wood is used as the wall material, the same heavy texture as that using solid wood can be obtained as the texture of the wall surface. In particular, if the wooden structure is a wooden building with an outer wall exposed to wind and rain, the joining line between the wooden members will not be exposed on the outer wall of the wooden building, so a sufficient aesthetic appearance of the outer wall can be secured. Is preferable.

In the means described above,
“The wall member is a pair of first wooden members spaced apart and opposed to each other, and a pair of first wooden members arranged opposite to each other in a direction intersecting with the separating direction of each first wooden member between the first wooden members. A wooden structure characterized in that it is composed of an assembled wood integrated with a second wooden member "
It is good.

  The above configuration specifically specifies the configuration of the wall material. According to the above configuration, the wall material is provided with a hollow portion inside, and the surfaces on which the bonding lines between the wooden members are exposed are the upper surface and the lower surface. It can be formed with a simple structure.

In the means described above,
"The wall material is stacked between a plurality of standing pillars,
The wall member and the column member are connected by a connecting member mounted in a mounting groove provided on each wall member ”
It is good.

  Conventionally, in order to mutually connect components such as wall materials and pillar materials that constitute a wooden structure, a tenon is provided at the end of one component, and a tenon hole is provided on the side of the other component, It is common practice to connect components to each other by inserting the tenons into the tenon holes.

  However, in the wooden structure configured as described above, since the wall material has a hollow portion, it is difficult to provide a tenon having sufficient strength on the end surface of the wall material. Therefore, in the above configuration, the column member and the wall member are not directly connected, but are connected via a connecting member mounted in each mounting groove of the column member and the wall member. Thereby, even if it does not employ | adopt the connection structure by the insertion of a tenon and a tenon hole, a column material and a wall material can be firmly connected.

  As described above, according to the present invention, there is provided a wooden structure that can obtain a heavy texture similar to that using solid wood as the texture of the wall surface even when the assembled wood is used as the wall material. can do.

  DESCRIPTION OF EMBODIMENTS Embodiments of a wooden structure according to the present invention will be described below in detail based on the drawings.

  FIG. 1 shows an example of a wooden structure 1 according to the present invention. This wooden structure 1 has a wall surface 20, and the wall surface 20 is formed by stacking wall materials 10 made of square wood-like assembled wood between column members 60 erected at appropriate portions. Is formed. In this example, a wooden building such as a log house is shown as the wooden structure 1, and the wall surface 20 constitutes an inner wall surface and an outer wall surface of the wooden building. Further, the column member 60 and the individual wall member 10 are used for each individual wall member 10 by using a separate connecting member 50 mounted in the mounting groove 23 a of the column member 60 and the mounting groove 23 b of the wall member 10. Are interconnected. Details of this connection will be described later.

  As shown in FIG. 2, the wall member 10 has a plurality of wooden members, specifically a pair of first wood members 30 and a pair of first members, so that a hollow portion 35 penetrating in the longitudinal direction is formed inside. The four wooden members of the two wooden members 40 are integrated. Specifically, it is as follows.

  Each of the pair of first wooden members 30 has a substantially square cross-sectional shape, and is disposed to be opposed to each other. Each of the pair of second wooden members 40 has a substantially square cross-sectional shape, and in a direction intersecting the separating direction of the first wooden members 30 between the first wooden members 30, specifically, The first wooden members 30 are integrated with the first wooden members 30 so as to be opposed to each other in a substantially orthogonal direction. Thereby, in this wall material 10, the substantially rectangular hollow part 35 penetrated over the full length of the wall material 10 is comprised by the back surface of each 1st wooden member 30, and the back surface of each 2nd wooden member 40. .

  Further, the second wooden member 40 is assembled in a buried manner between the pair of first wooden members 30 so as to be substantially flush with the side end surfaces (upper and lower end surfaces in the drawing) of the first wooden member 30. Yes. Therefore, in this wall material 10, the joint line 11 between each first wooden member 30 and each second wooden member 40 is exposed on the upper surface and the lower surface of the wall material 10. And in the wooden structure 1, since the wall material 10 similarly comprised is piled up and the wall surface 20 is formed, only the 1st wooden member 30 is exposed to the surface of both an outer wall surface and an inner wall surface. The joining line 11 between each first wooden member 30 and each second wooden member 40 is not exposed to the wall surface 20. Therefore, the wall surface 20 has an appearance as if it was formed by stacking solid wood, and the texture of the wall surface 20 is as heavy as that formed using solid wood. Yes.

  Furthermore, a convex upper surface guide portion 38 a is provided on the upper surface of the wall material 10 along the longitudinal direction of the wall material 10, and a concave lower surface guide portion 38 b is provided on the lower surface along the longitudinal direction of the wall material 20. Is provided. Specifically, the upper surface guide portion 38 a is configured by the step portion formed on the upper end surface of the first wooden member 30, and the lower surface guide portion is formed by the step portion formed on the lower end surface of the first wooden member 30. 38b is configured. Here, in this example, the upper surface guide portion 38a and the upper surface guide portion 38a and the lower surface guide portion 38b are arranged so that the joining line 11 between the first wooden member 30 and the second wooden member 40 is disposed inside the upper surface guide portion 38a and the lower surface guide portion 38b. A lower surface guide portion 38b is formed.

  When the wall material 10 having the upper surface guide portion 38a and the lower surface guide portion 38b is stacked, the lower surface guide portion 38b of the upper wall material 10 is uneven on the upper surface guide portion 38a of the lower wall material 10. The upper wall material 10 is precisely aligned with the lower wall material 10 and is stacked well with little rattling. In addition, although the upper surface guide part 38a may be concave and the lower surface guide part 38b may be convex, the above-described aspect is preferable. This is because if the upper surface guide portion 38a of the lower wall member 10 is convex, moisture such as rainwater is difficult to accumulate in the upper surface guide portion 38a. Moreover, about the dimension of mutual uneven | corrugated fitting of the upper surface guide part 38a and the lower surface guide part 38b, it is good to set to 1-10 mm, Preferably, it is 2-8 mm, More preferably, it is 3-5 mm. This is because if the dimension is too small, good alignment cannot be realized, while if the dimension is too large, the height of the wall material 10 itself becomes large, and the first wood constituting the entire height of the wall material 10 This is because a wide wood is required as the member 30.

  The configuration of the upper surface guide portion 38a and the lower surface guide portion 38b is not limited to the above-described configuration, and the second wooden member 40 protrudes from the first wooden member 30 on the upper surface of the wall member 10, and the protruding first 2 The convex upper surface guide portion 38a may be formed by the side surface and the upper surface of the wooden member 40. Further, on the lower surface of the wall member 10, the second wooden member 40 is buried in the first wooden member 30, and the concave lower surface guide portion is formed by the lower surface of the second wooden member 40 and the rear surface of the first wooden member 30 to be buried. 38b may be formed. According to such an aspect, the 1st wooden member 30 and the 2nd wooden member 40 are assembled | attached, even if it does not give shaping | molding processes, such as cutting, to the 1st wooden member 30 itself or the 2nd wooden member 40 itself. Thus, the upper surface guide portion 38a and the lower surface guide portion 38b can be formed.

  Next, the mutual assembly of the first wooden member 30 and the second wooden member 40 will be described in detail with reference to FIG. In FIG. 3, illustrations of configurations that are not directly related to assembly, such as the upper surface guide portion 38a and the lower surface guide portion 38b, are omitted.

  The central portion of the back surface of the first wooden member 30 is substantially convex. On the side surface of the substantially convex portion, a concave portion 31 b that is recessed in the width direction of the first wooden member 30 and the first wooden member 30. Convex portions 31a projecting in the width direction of the first wooden member 30 are extended over the entire length in the longitudinal direction of the first wooden member 30, respectively. And the to-be-latched part 31 is comprised by these recessed parts 31b and the convex parts 31a. On the other hand, on both side portions of the back surface of the second wooden member 40, a concave portion 41b that is recessed in the thickness direction of the second wooden member 40 and fits with the convex portion 31a of the first wooden member 30, and the second wooden member A convex portion 41 a that protrudes in the thickness direction of 40 and engages with the concave portion 31 b of the first wooden member 30 extends over the entire length of the second wooden member 40 in the longitudinal direction. And the latching | locking part 41 which latches the to-be-latched part 31 of the 1st wooden member 30 is comprised by these recessed parts 41b and the convex part 41a. As described above, the first wooden member 30 and the second wooden member 40 are provided with the locked portion 31 and the locking portion 41 that are locked with each other, and a pair of first wooden members arranged to face each other. Each member 30 has its locked portion 31 locked to the locking portions 41 of the pair of second wooden members 40 attached from both sides, and the mutual movement is restricted, and is opposed and separated. It is fixed with.

  Note that, as in this example, the engaged portion 31 of the first wooden member 30 is configured to have both the concave portion 31b and the convex portion 31a, and the engaging portion 41 of the second wooden member 40 is configured as the convex portion. It is not limited to having both of 41a and the recess 41b, but one of the engaged portion 31 or the engaging portion 41 is configured to have at least the recesses 31b and 41b, and the other is set to the recesses 31b and 41b. It may be configured to have at least the convex portions 41a and 31a that are fitted to each other, or the engaged portion 31 and the engaging portion 41 are not engaged with the concave and convex portions, but other methods such as hooking and clamping. It is good also as a thing of the form which can implement | achieve latching by. Moreover, the latching | locking part 41 and the to-be-latched part 31 should just mutually latch, even if the 1st wooden member 30 side is made into a latching | locking part, and the 2nd wooden member 40 side is made into the to-be-latched part. Good.

  Since the pair of second wooden members 40 assembled between the pair of first wooden members 30 is inadvertently detached as they are, the first wooden member 30 and the second wooden member 40 are firmly integrated as a whole. The resulting wall material 10 is not. Therefore, in this example, the wedge member 37 is provided between the first wooden member 30 and the second wooden member 40, and the wedge member 37 prevents the second wooden member 40 from being removed from the first wooden member 30. Prepared disconnection is prevented. Specifically, it is as follows.

  The thickness direction of the first wooden member 30 which is a direction different from the concave and protruding directions of the concave portion 31b and the convex portion 31a, more specifically, a direction substantially orthogonal to both side portions of the back surface of the first wooden member 30 A first groove portion 32 that is recessed and extends over the entire length in the longitudinal direction is recessed. On the other hand, on both side surfaces of the second wooden member 40, a direction different from the concave and protruding directions of the concave portion 41 b and the convex portion 41 a so as to face the first groove portion 32 of the first wooden member 30, more specifically, A second groove 42 that is recessed in the width direction of the second wooden member 40, which is a substantially orthogonal direction, is provided so as to extend over the entire length in the longitudinal direction. The first groove 32 and the second groove 42 constitute a substantially rectangular hole 36 that penetrates the entire length of the wall member 10.

  In this hole portion 36, a member formed of a resin filled in the hole portion 36 and cured, or a shape corresponding to the hole portion 36 in advance, is inserted into the hole portion 36 from the longitudinal direction of the wall material 10. A wedge member 37 made of an appropriate member such as a member is provided. The wedge member 37 prevents the second wooden member 40 from being inadvertently detached from the first wooden member 30, and the first wooden member 30 and the second wooden member 40 are firmly integrated as a whole. A wall material 10 is formed.

  In addition, in the wooden structure 1 of this example, the wall material 10 is comprised by the assembly | attachment wood which assembled | attached the 1st wooden member 30 and the 2nd wooden member 40, and was used as the square material as a whole. In the same manner, the first wooden member 30 and the second wooden member 40 are assembled to form a square member as a whole.

  By the way, the assembly wood is not limited to the above-described structure, and a plurality of wooden members such as the first wooden member 30 and the second wooden member 40 are bonded with an adhesive or the like, fastened with bolts, or nailed. For example, the above-described various integration methods may be combined as appropriate.

  Further, the surface of the first wooden member 30 is not limited to a planar shape, and may be an arcuate surface shape. In such an aspect, it can be set as the log house-like wall surface 20 as if log materials were stacked.

  Further, the pair of wooden members such as the first wooden member 30 and the second wooden member 40 is not limited to the same shape, and may have a different shape. For example, one of the pair of first wooden members 30 has a planar surface and the other has a circular arc surface so that one of the outer wall surface or the outer wall surface is a flat wall surface. On the other hand, the outer wall surface or the other of the outer wall surfaces can be a log house-like wall surface 20 as if logs are stacked. In particular, with respect to the interior surface, the surface of the first wooden member 30 on the inner wall surface serving as the interior surface has a planar shape, and the surface of the first wooden member 30 on the outer wall surface serving as the exterior surface has an arcuate shape. On the other hand, the exterior surface can be made into a wooden structure 1 having an excellent log house-like texture.

  Further, the assembly wood is not limited to the integration of the four wooden members of the pair of first wooden members 30 and the pair of second wooden members 40, but two, three, or five or more. A wooden member may be integrated. Here, when the wall material 10 is composed of assembled wood, a plurality of wooden members may be integrated to form the assembled wood so that the joint lines 11 between the wooden members are exposed on the upper surface and the lower surface. . For example, a plurality of wooden members may be integrated in parallel in the thickness direction of the wall material 10.

  Next, the connection between the column member 60 and the wall member 10 will be described in detail.

  As shown in FIG. 4, a mounting groove 23 a having a dovetail shape, more specifically, a substantially dovetail shape in cross section, is recessed along the height direction on the side surface of the column member 60. 23 a is open to the upper end of the column member 60.

  On the other hand, a mounting groove 23b having a dovetail shape, more specifically a substantially T-shaped cross section, is provided in the end surface of the wall member 10 along the height direction. Here, although the mounting groove 23 b is open on the upper surface of the wall material 10, it is closed on the lower surface of the wall material 10, and does not penetrate above and below the wall material 10, so that it is an end of the wall material 10. Is not divided in the thickness direction of the wall material 10 over the entire height. Accordingly, even if the mounting groove 23b is provided, sufficient strength of the end portion of the wall material 10 is ensured.

  The column member 60 and the wall member 10 have a column member side mounting portion 51 mounted on the mounting groove 23a of the column member 60 on one end side, and are mounted on the mounting groove 23b of the wall member 10 on the other end side. And is connected by a connecting member 50 made of an appropriate material such as wood, resin, metal or the like. Here, the column member side mounting portion 51 of the connecting member 50 is formed in an ant shape that fits into the mounting groove 23a of the column member 60, more specifically, a shape in which the mounting groove 23a of the column member 60 and male and female are inverted. The wall member side mounting portion 52b of the connecting member 50 has an ant shape that fits into the mounting groove 23b of the wall member 10, more specifically, a shape in which the mounting groove 23b of the wall member 10 and the male and female are inverted. Thus, the connecting member 50 is mounted on both the column member 60 and the wall member 10 without rattling. Therefore, the column member 60 and the wall member 10 are firmly connected by the connecting member 50 without rattling.

  In the operation of connecting the pillar member 60 and the wall member 10 by the connecting member 50, the connecting member 50 is inserted into the mounting groove 23 b of the pillar member 60 from above the pillar member 60 with the wall member 10 disposed between the pillar members 60. The column member side mounting portion 51 is inserted, the connecting member 50 is lowered along the column member 60, and the wall member side mounting portion 52 of the connecting member 50 is inserted into the mounting groove 23b of the wall member 10 from above the wall member 10. That's fine. Further, in this example, since the mounting groove 23b of the wall material 10 is closed by the lower surface of the wall material 10, the individual connecting members 50 are mounted in each of the plurality of wall materials 10 to be stacked. However, in a mode in which the mounting grooves 23b of the wall material 10 are opened on both the upper surface and the lower surface of the wall material 10, the mounting grooves 23b of the stacked wall materials 10 communicate with each other. . Therefore, in such an aspect, the common connecting member 50 may be mounted across the plurality of stacked wall members 10.

  In this example, since the column member side mounting portion 51 of the connecting member 50 is ant-fitted into the mounting groove 23 a of the column member 60, the connecting member 50 must be lowered from the upper end of the column member 60. Therefore, the shape of the column-side mounting portion 51 of the connecting member 50 is secured with respect to the mounting groove 23 a of the column member 60 so that the connecting member 50 can be smoothly lowered with respect to the column member 60. It is preferable to have a shape. Even in such a mode, as the form of the connecting member 50, when the wall material side mounting portion 52 is mounted in the mounting groove 23b of the wall material 10, the column material 60 and the wall material 10 are attracted to each other. By setting to the form, it is possible to realize a firm connection between the column member 60 and the wall member 10 without rattling.

  By the way, a concave guide portion 24 a is extended on the side surface of the column member 60 along the height direction of the column member 60. On the other hand, the end face of the wall member 10 is provided with a convex engaging portion 24b that engages with the guide portion 24a, more specifically, a concave-convex fitting. In the state where the end surface of the wall member 10 is abutted against the side surface of the column member 60, the mounting groove 23a of the column member 60 and the mounting groove of the wall member 10 are engaged by mutual engagement between the guide portion 24a and the engaging portion 24b. 23b is accurately aligned. Therefore, the connecting member 50 can be satisfactorily mounted in the mounting grooves 23a and 23b.

  The guide portion 24a is not limited to a concave shape, and may be a convex shape. The engaging portion 24b is not limited to a convex shape, and may be a concave shape. Moreover, since the guide part 24a and the engaging part 24b should just be a thing which can position the column material 60 and the wall material 10 mutually, it does not require a large dimension uneven | corrugated fitting, but a small dimension If it is too much, accurate alignment cannot be realized. On the other hand, if the size is too large, it becomes difficult to insert the wall material 10 from the side between the column members 60, and the work of arranging the wall material 10 between the column members 60 becomes complicated. Therefore, the size of the concave / convex fitting is set to 1 to 10 mm, preferably 2 to 8 mm, and more preferably 3 to 5 mm.
