Description

  The present invention relates to a connection structure of wooden structures, and more specifically, the base material in a wooden structure having a wooden base material that forms a base and a wooden pillar material erected on the base material. And the column structure.

  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 wooden furniture, etc. There are some which have a wooden base material that forms a base material and a wooden pillar material that is erected on the base material. And in such a wooden structure, in order to connect a base material and a pillar material conventionally, the connection structure as shown, for example in FIG. 5 was employ | adopted. Specifically, in this connection structure, a boss 121 formed at an end portion of the pillar material 120 is inserted into a horn hole 111 formed in an appropriate portion of the base material 110, and the pillar is formed on the upper surface of the base material 110. The material 120 is connected.

  The above prior art is a general matter, and the present applicant has no particular knowledge of the literature specifying the prior art at the time of filing the present application.

  In the above-described conventional connecting structure, wood is required to be longer than the pillar length, which is the actual dimension of the pillar, as the material of the pillar material, so that unnecessary consumption of the wood has been forced. In addition, when so-called “material removal” in which a material having a desired length is cut out from the lumbered lumber, a length that allows for a tense must be calculated as the length of the material to be cut out. For this reason, the material which cannot obtain desired column length was taken by the artificial calculation mistake, and when this material was not used and was discarded, wood was sometimes consumed unnecessarily. Furthermore, due to a mistake in machining the column material and the base material, the column material and the base material can no longer be used. By discarding the column material and the base material, the wood may be consumed unnecessarily. Thus, the conventional connection structure consumes wood resources unnecessarily.

  By the way, when a processing error occurs in the column material and the base material hole, there is a case where the column material and the base material do not need to be discarded, and the processing error can be dealt with by correcting the column and the base material. However, in order to correct the tenon or the tenon hole, the column material itself or the base material itself must be corrected, and this correction processing becomes complicated. In particular, when the pillar material or the base material is large and heavy, handling of the pillar material or the base material is not easy, and thus the above-described correction processing becomes more complicated. Moreover, when correction is not completed at once, the attachment and detachment of the pillar material and the base material must be repeated, and the correction processing becomes even more complicated. Therefore, the conventional connection structure cannot easily cope with the processing error when a processing error occurs in the connection portion between the base material and the column material.

  The present invention has been made in view of the above-described actual situation, and can suppress unnecessary consumption of wood resources, and even if a processing error occurs in the connection portion between the base material and the pillar material, this processing is performed. An object is to provide a connection structure between a base material and a pillar material in a wooden structure that can easily cope with mistakes.

The main means for solving the above problems are:
"A wooden base material that has mating holes and forms the base of a wooden structure;
A wooden pillar material that has a fitting hole and is erected on the base material;
On one end side, it has a base side insertion part inserted into the fitting hole of the base material, and on the other end side, it has a column side insertion part inserted in the fitting hole of the pillar material. The connecting structure of the base material and the pillar material in the wooden structure characterized by including a connecting member for connecting the base material and the pillar material "
It is.

  In the connection structure configured as described above, since it is not necessary to provide a tenon on the pillar material, the material of the pillar material can be made shorter than the conventional connection structure by the amount of the tenon. Therefore, useless consumption of wood resources can be suppressed.

  In addition, since there is no need for the column material, the length of the material can be simply calculated from the column length, which is the actual column size, when taking the material of the column material, and human calculation errors can be avoided. It can be made difficult to occur. Therefore, it is possible to reduce the possibility that the wood is discarded due to a mistake in taking the material due to a calculation error. From this point as well, unnecessary consumption of the wood resources can be suppressed.

  By the way, in the conventional connection structure, when a serious processing error that cannot be dealt with by correcting itself is generated in the tenon and the tenon hole, the column material and the base material are forced to be discarded. On the other hand, in the connection structure having the above-described configuration, even if a processing error that cannot be dealt with by correction of the fitting hole itself occurs in the fitting hole of the base material and the fitting hole of the column material, Since the connecting member is interposed between the column members, it may be possible to cope with a processing error by correcting the connecting member or changing the form of the connecting member. For example, if a processing error occurs when the fitting hole of the base material or the fitting hole of the column material is too small, the base-side insertion part can be fitted well into this small fitting hole. In some cases, the processing errors can be dealt with by making the column side insertion portion small. On the other hand, if the mounting hole for the base material or the fitting hole for the column material is too large, the base side insertion is performed so that the large fitting hole can be fitted well. The processing error may be dealt with by specially using a connecting member having a large part or a column-side insertion part. Also, if a misalignment occurs in the fitting hole of the base material or the fitting hole of the column material, the base side insertion part or the column side insertion part can be absorbed so that this positional deviation can be absorbed. In some cases, the above-described processing errors can be dealt with by specially using connecting members in which the shaft cores of the fitting portions are eccentric from each other by the amount of positional deviation. Thus, with this connection structure, the allowable range of processing errors that can be dealt with is widened, and it is possible to flexibly cope with processing errors. Therefore, it is possible to reduce the number of base materials and column materials discarded due to processing errors, and also from this point, unnecessary consumption of wood resources can be suppressed.

  In addition, even if there is a processing error in the mating hole of the base material or the mating hole of the column material, this processing error can be dealt with by the connecting member, so the column material itself or the base material itself is directly modified. There is no need to make corrections. Therefore, it is possible to easily cope with processing errors. Further, since the connecting member is inserted into the fitting hole of the column material or the base material, it is naturally smaller than the column material or the base material and has a size that is easy to handle. Therefore, in particular, in the case of dealing with a processing error by performing a correction process on the connecting member, the correction process can be performed more easily than when the column material itself or the base material itself is corrected.

  In addition, the connection structure according to the present invention does not exclude the combined use of a connection method other than the connection method using a connection member. For example, the joint surfaces of the base material and the column material are bonded to each other with an adhesive. Use a method of bonding together, or use a method of connecting the connecting part of the base material and the pillar material by fitting the concave and convex portions together, or over the top surface and side surface of the base material and the side surface of the pillar material It is also possible to use other connecting members in combination, such as a substantially L-shaped or a substantially T-shaped fitting to be attached.

In the means described above,
“The pillar material is formed by integrating a plurality of wooden members so that the fitting hole is formed at the end portion, and the connecting structure of the base material and the pillar material in the wooden structure,” "
It is good.

  The end face of the pillar material is a small facet, and if a fitting hole is to be formed in such a small facet, a complicated working work is required, and a processing error is likely to occur. On the other hand, in the said structure, since the pillar material by which the fitting hole was formed in the edge part is comprised by integrating a some wooden member, it is not necessary to form a fitting hole separately. Therefore, it is possible to omit a complicated machining operation on the facet, and it is also possible to provide the fitting holes for the column members with high accuracy.

  In addition, although it does not specifically limit as a concrete aspect which integrates a some wooden member so that a fitting hole may be formed in an edge part, and makes it a pillar material, For example, by the back surface of a some wooden member A plurality of wooden members are arranged side by side around the axis of the column material so that a hollow portion that penetrates the entire length of the column material is formed, and a fitting hole is formed at the end of the hollow portion. A plurality of wooden members whose recesses are formed in advance at the end may be integrated and integrated, and each recess may form a fitting hole, or at the end A wooden member in which a fitting hole is formed in advance and another wooden member may be provided continuously in the length direction of the column member. Moreover, as a method of integrating a plurality of wooden members, various methods such as adhesion with an adhesive, fastening with bolts, nail fastening, and uneven fitting between wooden members can be exemplified.

  Here, a plurality of wooden members are integrated so that a hollow portion penetrating the entire length of the pillar material is formed by the back surfaces of the plurality of wooden members, and an end portion of the hollow portion forms a fitting hole. It is preferable to use a pillar material. By doing in this way, even if it does not give a special process with respect to each wooden member, a fitting hole can be provided in the edge part of a pillar material. Moreover, in the pillar material provided with the hollow part, the weight can be reduced as compared with the pillar material not provided with the hollow part of the same size. And since the dimension of a cross section becomes large by the part of a hollow part, a larger-sized column material can be formed from a small-sized wooden member. Furthermore, if it is a pillar material used as a building material such as a log house component, a wooden house frame, or a building interior material, the hollow portion can improve the heat insulation effect and sound insulation effect effective as a building material. . Moreover, since the area which touches air spreads only the part of an internal hollow part, the hygroscopic property and humidification which are effective as a building material can be improved. In addition, the hollow portion inside can be used as a wiring region such as an electric wire or a telephone line, or a piping region such as a water pipe or a gas pipe.

In the means described above,
"The connecting member is a connecting structure between a base material and a column material in a wooden structure, wherein at least one of the base side insertion portion or the column side insertion portion is formed in a columnar shape"
It is good.

  For example, if both the base-side insertion part and the column-side insertion part in the connecting member are square columnar shapes such as a quadrangular columnar shape, in the column member erected on the upper surface of the base material with this connecting member interposed, There is no degree of freedom for rotation around the axis. In such an aspect, in the fitting hole of the base material and the fitting hole of the column material, if the angle with respect to the axis of the column material is not accurately determined, the direction of the column material standing on the base material is determined. It will not be possible to accurately match. On the other hand, in the said structure, since at least one of the base side insertion part or the column side insertion part in a connection member is formed in the column shape, it stood on the base material through this connection member The rotation of the column member around its axis is not constrained by the connecting member, and the orientation can be freely changed. Therefore, even if the angle with respect to the axis | shaft of a pillar material is not correctly calculated | required in the fitting hole of a base material, or the fitting hole of a pillar material, direction of a pillar material can be match | combined correctly. In addition, the fitting hole of the base material or the fitting hole of the column material into which the base side insertion portion or the column side insertion portion formed in a columnar shape is naturally formed in a circular shape. And since such a circular fitting hole can be drilled by a simple process such as drilling, the circular fitting hole is replaced with a square fitting hole in the base material or the pillar material. In comparison, it can be easily molded.

In the means described above,
“The locked portion provided on one of the base material or the pillar material,
A wooden structure comprising: a locking portion provided on the other of the base material or the pillar material, the locking portion locking the locked portion and restricting rotation of the pillar material around the axis relative to the base material. Connection Structure between Base Material and Column Material "
It is good.

  If there is a backlash in the insertion between the fitting hole of the base material and the base-side connecting part of the connecting member, or the fitting hole of the column material and the column-side connecting part of the connecting member, Therefore, it is necessary to separately align the orientation of the column material. In particular, in the aspect in which the one end side of the connecting member is formed in a columnar shape, the column material freely rotates around the axis, and therefore the alignment operation of the column material with respect to the base material is essential. On the other hand, in the above configuration, the rotation around the axis of the column material is restricted by locking the other locking portion to one locked portion of the base material or the column material. The alignment work for the orientation of the pillar material is not required, and the work of standing the pillar material on the base material can be simplified.

  In addition, as long as the locking portion and the locked portion are locked with each other, the mode is not particularly limited. For example, a recess in which the pillar material is fitted on the upper surface of the base material is provided. It is also possible to regulate the rotation around the axis of the column material by bringing the side surface of the column material into contact with the side wall surface of the recess, or to provide a recess in which the base material is fitted on the end surface of the column material. The rotation of the column material around the axis may be restricted by bringing the side surface of the base material into contact with the side wall surface of the recess. In these aspects, the concave portion serves as a locking portion, and both side surfaces of the pillar material and both side surfaces of the base material serve as locked portions that are locked to the locking portion.

  As described above, according to the present invention, it is possible to prevent the wood resources from being consumed unnecessarily, and even if a processing error occurs in the connecting portion between the base material and the column material, the processing error can be easily dealt with. It is possible to provide a connection structure between a base material and a pillar material in a wooden structure that can be made.

  DESCRIPTION OF EMBODIMENTS Embodiments of a connection structure between a base material and a pillar material in a wooden structure according to the present invention will be described below in detail based on the drawings.

  In FIG. 1, an example of the connection structure of the base material 10 and the pillar material 20 in the wooden structure which concerns on this invention is shown. This connection structure is a structure in which a wooden base material 10 serving as a base of various wooden structures and a wooden pillar material 20 erected on the base material 10 are connected using a connection member 60.

  The base material 10 is made of solid wood that is made of raw wood and has a substantially square cross section, and is formed in an appropriate portion of the base material 10 in a vertically penetrating manner by drilling. A substantially circular fitting hole 11 is formed. On the other hand, the column member 20 has a substantially square hollow portion 21 penetrating through a plurality of wooden members formed by processing lumber made from raw wood into a desired cross-sectional shape in the length direction by the back surface of each wooden member. It is assembled and integrated so as to be configured, and a substantially square fitting hole 22 formed by a part of the hollow portion 21 is provided at the lower end portion of the column member 20. . A connecting member 60 is inserted into the fitting hole 11 of the base material 10 and the fitting hole 22 of the pillar material 20, and the base material 10 and the pillar material 20 are connected by the connecting member 60.

  The connecting member 60 is integrally formed in a rod shape from wood, and includes a columnar base-side insertion portion 61 that is inserted into the fitting hole 11 of the base material 10 on one end side, and the other end. On the side, a prismatic columnar insertion portion 62 having a prismatic shape inserted into the insertion hole 22 of the columnar material 20, more specifically, a prismatic columnar shape having a substantially square cross section is provided. And this connection member 60 inserts the base side insertion part 61 in the fitting hole 11 of the base material 10, and inserts the column side insertion part 62 in the fitting hole 22 of the column material 20, The base material 10 and the pillar material 20 are connected in such a manner that the pillar material 20 is erected at a portion where the fitting hole 11 is provided on the upper surface of the material 10. The insertion part 61 and the column side insertion part 62 are formed coaxially. Here, in this example, both ends of the connecting member 60 are respectively fitted into the base material 10 and the column material 20, and the whole is concealed when the base material 10 and the column material 20 are connected. However, the form of the connecting member 60 is not limited to this, and the central part thereof is a large one that is not fitted in either the base material 10 or the pillar material 20, and the large part is exposed. Also good.

  The connecting member 60 may be formed of a material different from wood, such as metal or resin, or a plurality of members formed of wood or other materials are integrated. May be. Here, when there is a problem that the dimensions and shape as designed are not secured for the fitting hole 11 of the base material 10 and the fitting hole 22 of the column material 20, the base side insertion of the connecting member 60 is performed. Since the above-mentioned problems can be eliminated by applying appropriate correction processing to the portion 61 and the column side insertion portion 62, the material constituting the connecting member 60 can be easily corrected for cutting, deformation, etc., such as wood or resin. It is preferable to use a material. Moreover, when the position of the fitting hole 11 of the base material 10 has shifted | deviated rather than the design position which the column material 20 should stand upright, the base side insertion part 61 and the column side insertion part 62 are shown. By using the connecting member 60 whose axis is eccentric with respect to each other, it is possible to absorb the misalignment of the fitting hole 11 of the base material 10, and thereby, the column material 20 at an appropriate portion of the base material 10. Can be erected.

  In a state where the base member 10 and the column member 20 are connected using the connecting member 60, the column-side insertion portion 62 of the connecting member 60 and the fitting hole 22 of the column member 20 are fitted in a substantially square shape. Therefore, the column member 20 does not freely rotate around its axis with respect to the connecting member 60, but the base-side insertion portion 61 of the connecting member 60 and the fitting hole 11 of the base member 10 are approximately. Because of the mutual fitting in a circular shape, the connecting member 60 rotates freely around its axis with respect to the base material 10. Therefore, the column material 20 connected to the base material 10 via the connection member 60 is freely rotated around its axis, and the orientation of the column material 20 with respect to the base material 10 can be accurately adjusted. Here, in this example, the base-side insertion portion 61 has a cylindrical shape and the column-side insertion portion 62 has a prismatic shape, but the column-side insertion portion 62 has a cylindrical shape, and the foundation-side insertion portion 61 has a rectangular shape. It may be columnar, or both the base-side insertion part 61 and the column-side insertion part 62 may be columnar.

  Further, in the connecting member 60 of the present example, the diameter of the columnar shape on one end side is smaller than the diagonal of the prismatic shape on the other end side, and more specifically, one side of a substantially square shape. The connecting portion, which has substantially the same dimension as the length and changes from a cylindrical shape to a prismatic shape, smoothly changes to a tapered shape, more specifically, an arc shape. That is, the connecting member 60 has a rod-like shape in which the columnar side is small in size and the prismatic side is large in width, and both ends are connected in a tapered shape. Therefore, for example, when the connecting member 60 is attached to the base material 10 prior to the column material 20 being erected on the base material 10, the base side insertion portion 61 is inserted into the fitting hole 11 of the base material 10. If the press fitting is appropriately performed, the connecting member 60 can be temporarily positioned and fixed on the upper surface of the base material 10, and the fitting hole 22 of the column member 20 is inserted into the column side insertion portion 62 of the connecting member 60. The work at the time of external fitting can be performed satisfactorily.

  By the way, a concave portion 12 is formed on the top surface of the base material 10 with the portion where the fitting hole 11 is formed as the bottom surface. The width dimension of the concave portion 12 is substantially the same as the width dimension of the column member 20. It has become. Therefore, the column member 20 erected on the upper surface of the base material 10 has its lower end portion fitted into the recess 12 of the base material 10, and the side wall of the recess 12 is in contact with the side surface of the lower end portion of the column member 20, The column member 20 is fixed in the correct orientation. Here, the said recessed part 12 of the base material 10 latches the both sides | surfaces of the pillar material 20, and controls the rotation around the axis | shaft of the pillar material 20, In this example, the said recessed part 12 of the foundation material 10 The locking portion 12 is configured, and both side surfaces of the lower end portion of the column member 20 are locked by the locking portion 12 to form a locked portion 23 that restricts the rotation of the column member 20 around the axis.

  In addition, about the aspect of a latching | locking part and a to-be-latched part, a mode as shown, for example in FIG. 2 may be sufficient. In this example, a recess 24 that fits the entire width of the base material 10 is provided on the lower end surface of the column member 20. Therefore, in this example, the locking portion 24 is configured by the concave portion 24 of the column member 20, and the locked portion 13 is configured by the upper portions of both side surfaces of the base material 10, and the locking portion 24 and the locked portion By the locking of 13, the column member 20 is restricted from rotating around the axis with respect to the base material 10. Moreover, about the aspect of a latching | locking part and a to-be-latched part, if it can mutually latch and can control the rotation around the axis | shaft of the pillar material 20 with respect to the base material 10, if it is mutually locked, Well, each of the base material 10 and the column material 20 is provided with unevenness to be fitted to each other, or a separate positioning plate or the like that is locked to one of the base material 10 or the column material 20 with respect to the other. What attached the member may be sufficient.

  In this example, the column member 20 is formed by integrating a plurality of wooden members as described above. Next, the configuration of the column member 20 will be described in detail with reference to FIG. The column member 20 is formed into a prismatic shape as a whole by assembling four wooden members, specifically, a pair of first wood members 30 and a pair of second wooden members 40 to each other.

  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 is separated from each other in a direction intersecting the separating direction of the first wooden member 30, specifically, in a substantially orthogonal direction. Are opposed to each other. Thereby, in this pillar material 20, the substantially square hollow part 21 penetrated over the full length of the pillar material 20 is comprised by the back surface of each 1st wooden member 30, and the back surface of each 2nd wooden member 40. As shown in FIG. The hollow portion 21 is configured to have a substantially square shape that is substantially the same shape as the column-side insertion portion 22 of the connecting member 60, and the lower end portion of the hollow portion 21 causes the column side of the connecting member 60. A fitting hole 22 into which the insertion part 62 is fitted is formed.

  In addition, the 2nd wooden member 40 is assembled | attached between the pair of 1st wooden members 30 so that it might become flush | planar with the side end surface (upper and lower end surfaces in the illustration) of the 1st wooden member 30. . Therefore, the first wooden member 30 is used such that the first wooden member 30 is disposed on the surface exposed to the front side of the building without exposing the joining line with the second wooden member 40 on the surface side of the first wooden member 30. Thus, the pillar material 20 can be suitably used as an exterior material or interior material as a building material.

  Next, the mutual assembly | attachment of the 1st wooden member 30 and the 2nd wooden member 40 is demonstrated.

  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. It will not become the pillar material 20 which became. Therefore, in this example, a wedge member 51 is provided between the first wooden member 30 and the second wooden member 40, and the wedge member 51 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 portion 32 and the second groove portion 42 constitute a substantially rectangular hole portion 50 that penetrates the entire length of the column member 20.

  In the hole 50, a member formed of a resin filled in the hole 50 and cured, or formed in a shape corresponding to the hole 50 in advance, and inserted into the hole 50 from the longitudinal direction of the column member 20 A wedge member 51 made of an appropriate member such as a member is provided. The wedge member 51 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 pillar material 20 is formed.

  By the way, in this connection structure, when the columnar material 20 is erected independently with respect to the base material 10, there is a case where the solid erected state of the columnar material 20 cannot be maintained only by the connection member 60 as described above. . In this case, for example, a separate connection member such as a plate-shaped connection fitting is attached between the base material 10 and the column member 20, and the separate connection member is used in combination. You may enable it to ensure the firm standing state of the material 20. FIG.

  For example, as shown in FIG. 4, other constituent members 70 such as wall materials are mounted between the plurality of pillar members 20, and each pillar member 20 is restrained by the other constituent members 70 on the side surfaces. In the wooden structure, since the standing state of each column member 20 with respect to the base material 10 becomes firm, it is possible to omit separately using a connecting member as described above. In the example shown in FIG. 4, a connecting portion 25 such as a dovetail groove or a hollow hole is provided on the side surface of the column member 20 over the entire length in the length direction. On the other hand, a connecting portion 71 such as a dovetail groove or a hollow hole is also provided at an end portion of another constituent member 70 such as a wall member disposed on the side surface of the column member 20. Then, a wedge-shaped connecting member 80 is attached to the connecting portion 25 of the column member 20 and the connecting portion 71 of the other component member 70, and a plurality of other component members 70 are stacked on the side surface of the column member 20. Thus, each column member 20 is maintained in a good standing state without using a separate connecting member.
