Description

Wall structure, wooden building, and how to build a wooden building

The present invention relates to a wall structure, a wooden building, and a method for constructing a wooden building. More specifically, wood is used as the main material of the skeleton to achieve carbon storage effect and energy saving effect, and it has good workability in a relatively narrow land, and has a robust wall structure, wooden building, and. Regarding the construction method of wooden buildings.

Traditionally, small buildings using the prefabricated method have been used as garages and warehouses. The prefabricated construction method has the advantage that the construction period at the construction site is shortened because the parts are produced at the factory by the precut or precast construction method. On the other hand, in the prefabricated method, steel frames and metal wall panels are often used as materials, so that a large amount of carbon dioxide is emitted and a large amount of energy is consumed in the production thereof.

As an example of a technique for solving such a problem, an invention as shown in Patent Document 1 has been proposed. The invention described in Patent Document 1 is a load-bearing surface material in which three or more pieces of square lumber shaft members having the same cross-sectional shape are erected on a base, and the side surfaces are brought into contact with each other to form a uniform surface. Therefore, the fixed integration applies two types of multiple wood screws having a length capable of penetrating one or two of the wood shaft materials to the same direction side for each wood shaft material. It is made by screwing and fastening to one or two timber shafts in contact with each other at appropriate intervals, and at each of the above screwed points, the length and diameter are almost the same as the length of the wood screw screwed into the point. It is a load-bearing surface material having a wooden shaft material structure, characterized in that a linear pilot hole is opened in advance.

According to the present invention, it is said that a plurality of timber screws screwed and fastened so as to straddle between a plurality of square lumber shafts can enhance the connected state of the lumber, and the bearing capacity of the wood shaft configuration. If the face material is adopted as the wall surface constituent material of the building, the above-mentioned steel frame and wall panel can be not used or the amount used can be reduced, and it is expected that the carbon dioxide emission amount in the production of the material can be reduced and the energy can be saved.

Japanese Patent No. 6522055

By the way, in the construction method using a general wooden shaft material, the pillar material is joined to the "base" laid horizontally at the bottom, and the tenon formed at the lower end of the pillar material and the tenon formed on the upper surface of the base are fitted. In many cases. When the wooden shaft material is vertically erected as in the invention described in Patent Document 1, a large number of mortises are formed on the upper surface of the base, so that the strength of the base (particularly the load bearing capacity in the horizontal direction). Is significantly reduced.

In the invention described in Patent Document 1, "a short fixing screw 6a is used for the base, and a part of the tip is screwed and fastened to the base 92 by diagonally penetrating from the main surface material 2. The joint portion between the main surface material 2 and the base 92 may be engaged with the horizontal hole and the horizontal hole. ”However, if fixing screws are placed for each pillar material, it takes a lot of time and effort, and the fixing screws. If only the joint with the base is supported, it can be a part that is vulnerable to external force from the horizontal direction (the load bearing capacity of the joint between the base and each pillar is low).

On the other hand, in recent years, there is a tendency for skilled workers in the construction field to be in short supply, and in order to perform mortise and tenon work involving the formation of mortises and tenons, or mortise and tenon work, which is a work that originally requires some skill, Wait for the turn of the skilled workers to start, or a non-skilled worker will be in charge of the work. However, waiting for the turn of a skilled worker leads to a delay in the construction period, and even if a person who is not a skilled worker is in charge of the work, the delay in the construction period is expected, and in addition, there is a possibility that sufficient work quality cannot be ensured.

The present invention has been devised in view of the above points, and uses wood as the main material of the frame to exert a carbon storage effect and an energy saving effect, and has good workability in a relatively narrow land. It is an object of the present invention to provide a wall structure having a robust structure, a wooden building, and a method for constructing a wooden building.

In order to achieve the above object, the wall surface structure of the present invention includes a foundation portion and a first wall surface portion constituting the first floor portion, and the foundation portion is formed from a concrete foundation main body portion and the foundation main body portion. The structure has a structure in which an erected plate-shaped vertical surface portion has a connecting portion provided so as to substantially coincide with the formation direction of the first wall surface portion, and the first wall surface portion stands with its axis vertically. It is a structure having a plurality of wooden columnar members whose lower portions are continuously arranged and arranged along the connecting portion, and a connecting structure portion connecting the adjacent columnar members. It should be noted that the term "substantially match" is used in the sense that it includes an exact match and also includes an aspect of substantially matching.

Here, the foundation portion can support the load of the first wall surface portion. By having the above-mentioned connecting portion, the foundation portion is an unskilled worker who arranges a plurality of columnar members in a continuous linear manner so that the lower portion of the columnar member is aligned with the connecting portion. However, it can be done accurately and easily. As a mode in which the lower portion of the columnar member is aligned with the connecting portion, for example, a mode in which the receiving groove portion formed on the lower end surface of each columnar member and the connecting portion are fitted, or a mode in which the lower side surface of each columnar member and the connecting portion are fitted. Examples thereof include a mode in which they are attached in contact with each other.

In the first wall surface portion, a plurality of wooden columnar members are continuously erected on the foundation portion, and adjacent columnar members are connected and integrated by a connecting structure portion, thereby partitioning the inside and outside of a building or the like. A wooden wall structure of a size can be formed at the work site.

As the columnar member, a prism having a quadrangular cross-sectional shape or the like is preferably used, but the columnar member is not limited to this. It may be a pillar material or the like. Further, the columnar member forms a recess such as a groove on one surface thereof, forms a convex portion such as a ridge in the opposite direction of the concave portion across the long axis of the column member, and fits the above-mentioned concave portion and the convex portion. It may be a structure in which adjacent columnar members are connected to each other.

By the way, when using a large panel constituting a building wall surface such as a general garage, a vehicle to be loaded and a crane vehicle for suspending the panel are required, but according to the above-mentioned wall structure, for example, it is difficult to carry in the large panel. A wall structure can be installed even in a narrow space, and in addition, it is difficult for vehicles loaded with large panels and crane vehicles to suspend them to enter the land in the back of narrow alleys away from the main road and the surrounding area. It is suitable for construction in a relatively small land where a house is built.

Further, in the first wall surface portion, a plurality of columnar members can be easily arranged in a straight line only by continuously aligning and arranging the lower portions of the columnar members along the connecting portion, and even an unskilled worker can easily arrange the first wall surface portion. Accurate and easy construction is possible. Further, the first wall surface portion can be formed as a one-sided wall surface structure by connecting adjacent columnar members by a connecting structure portion. Furthermore, since the first wall surface portion is formed by erection of each columnar member in order from the end side in the longitudinal direction of the foundation portion along the connecting portion and connecting adjacent columnar members. Workability is also good in that the upper and lower ends of the columnar member, which is a constituent material, can be easily aligned.

The "connecting structure portion" includes, for example, a screw bolt that penetrates in an intersecting direction with respect to the axial direction of one columnar member and is bored to a length extending to an adjacent columnar member, or a shaft of each columnar member. Examples thereof include combinations of bolts and nuts provided in the intersecting direction with respect to the direction, and these are preferably used because the members do not appear on the wall surface after completion and the appearance is good. However, the "connecting structure" is not limited to screw bolts and the like, but is a structure in which an adhesive is applied between each columnar member, a structure in which a screw bolt or the like and an adhesive are combined, a plate metal fitting or a mortise and tenon. It is used in the sense that it also includes a connecting structure by a known means such as.

The wall surface structure of the present invention can be suitably used as a side wall of a house, a store, a garage, a storeroom, or the like. Since the wall surface structure uses wood as a constituent material of the first wall surface portion, it exhibits a carbon storage effect due to the material and an energy saving effect due to the reduction of energy generated in the production of building materials. A carbon storage effect and an energy saving effect will be added to the building to which the wall structure is applied. In addition, the wall surface structure of the present invention has a structure that does not use a base having a large number of mortises formed on the upper surface, and therefore has a robust structure as compared with a general wooden wall surface structure.
That is, the wall surface structure of the present invention has a carbon storage effect and an energy saving effect, and has good workability in a relatively narrow land, and has a robust structure.

In addition, each columnar member has a lower receiving groove portion formed on the bottom surface in which the vertical surface portion fits, and the formation directions of the lower receiving groove portions coincide with each other on substantially the same line in the connected state of the columnar members, and are perpendicular to the lower receiving groove portions. When the structure is such that the surface portion is fitted and the foundation portion and the first wall surface portion are connected, the workability is further improved. Specifically, in constructing the first wall surface portion, while fitting the connecting portion provided on the foundation portion and the lower receiving groove portion of the columnar member, a plurality of the connecting portions are erected in order from the end side in the longitudinal direction of the foundation portion. It is easy to align the upper and lower ends of the columnar member, which is a constituent material, and the workability is improved. It should be noted that the term "substantially on the same line" is used in the sense that it includes on the same line and also includes aspects that generally match on the same line.

Further, when the connecting portion is composed of a long L-shaped angle material and an anchor bolt for fixing the L-shaped angle material to the foundation main body, the work of providing the connecting portion on the foundation main body is further performed. It can be done easily. Specifically, the horizontal portion of the L-shaped angle material is a portion that abuts and is fixed to the basic body portion of the foundation, and the vertical portion is a vertical surface portion. Further, the anchor bolt is inserted into, for example, a hole formed through the horizontal portion in the plate thickness direction, and the shaft portion embedded in the foundation main body forms a fixing structure with the foundation main body.

Furthermore, with the configuration of this connection part, the material cost can be reduced because the material is easy to procure, and the work can be easily performed even by an unskilled worker, so that it is easy to procure the number of workers. Labor costs can also be reduced, and as a result, construction costs can be further reduced.

Further, as the connecting portion, plate portions erected in an arrangement in which the plate surfaces intersect with the vertical surface portion are provided at a plurality of locations at predetermined intervals, and each columnar member has a lower receiving groove in which the plate portion is accommodated. The first pillar formed on the lower end surface and the second pillar arranged between the first pillars are included, and the lower side surfaces of the first pillar and the second pillar and the vertical surface portion are brought into contact with each other. If the structure is such that the second pillar is sandwiched between the first pillar in which the plate portion is fitted in the lower receiving groove portion and the foundation portion and the first wall surface portion are connected, the workability is further improved. are doing.

Specifically, in constructing the first wall surface portion, the plate portion of the connection portion provided on the foundation portion and the lower receiving groove portion of the first pillar are fitted, and are perpendicular to the lower side surfaces of the first pillar and the second pillar. By bringing the face portion into contact with the first pillar and sandwiching the second pillar between the first pillars, it is easy to erect a plurality of the foundation parts in order from the end side in the longitudinal direction, and the upper end of the columnar member which is a constituent material. The alignment of the lower end is easier and the workability is improved.

And since only the first pillar is fitted to the plate portion instead of all the columnar members, the second pillar does not need to be fitted to the plate portion, and the labor of work can be reduced. Further, since it is not always necessary to form the lower receiving groove portion on the second pillar, the labor and cost of the same processing are not required (note that the mode in which the lower receiving groove portion is formed on the second pillar is excluded. is not).

Further, the connecting portion includes a vertical portion corresponding to a vertical surface portion, a horizontal portion bent from the lower end edge portion of the vertical portion, and a side end edge having one side edge of the same vertical portion, and a side end edge located downward in use. If is composed of a long angle material having a plate portion fixed to the same horizontal portion and a fixing tool for fixing the same angle material to the foundation main body portion, the connection portion is provided on the foundation main body portion. The work of providing can be performed more easily.

Specifically, the horizontal part of the angle material is the part that abuts and is fixed to the foundation body part, and the vertical part is the vertical surface part. Further, since the plate portion is fixed to the vertical portion and the horizontal portion, the structure is such that the space between the vertical portion and the horizontal portion does not easily expand, and the rigidity is improved. Furthermore, the fixture forms a fixing structure between the horizontal portion and the foundation main body portion. For example, an anchor bolt is mentioned as the fixture, and the anchor bolt is formed so as to penetrate in the plate thickness direction of the horizontal portion. An example may be mentioned in which a shaft portion inserted into the hole and embedded in the foundation main body forms a fixed structure with the foundation main body.

Furthermore, with this connection part configuration, material costs can be reduced because it can be easily formed with materials that are easy to procure, and even unskilled workers can easily perform the work, so it is possible to procure workers. It is easy and labor costs can be reduced, and as a result, construction costs can be further reduced.

Further, a second wall surface portion constituting the upper floor portion and a connecting tool for connecting the second wall surface portion and the first wall surface portion are further provided, and the connecting tool has a bottom surface of the second wall surface portion in the installed state. The horizontal part to be received, the vertical part standing above the horizontal part, and the vertical part and the horizontal part are fixed at the arrangement where the plate surface intersects the vertical part, and are provided at multiple places with a predetermined interval. It has a first plate portion that has been formed and a second plate portion that is vertically hung on the lower surface of the horizontal portion. The two wall surface portions were erected with the axis vertically, and the lower portions thereof were continuously aligned and arranged along the vertical portion of the fitting, and a lower receiving groove in which the first plate portion was accommodated was formed on the lower end surface. It has a first pillar, a plurality of wooden columnar members including a second pillar arranged between the first pillars, and a connecting structure portion for connecting adjacent columnar members, and has a first wall surface. The second plate portion is fitted into the upper receiving groove of the portion, the first pillar of the second wall surface portion and the lower side surface of the second pillar are brought into contact with each other, and the lower receiving groove portion of the first pillar is brought into contact with the vertical portion. In the case of a structure in which the first wall surface portion and the second wall surface portion are connected by a connector in which the first plate portion is fitted and the second pillar is sandwiched between the first pillars, the connector is connected. Due to the action and effect of each part such as, the second wall surface portion constituting the upper floor portion can be efficiently provided directly above the first wall surface portion.

For details, attach the connector to the upper part of the installed first wall surface. At this time, the connector fits the second plate portion into the upper receiving groove of the first pillar in the first wall surface portion. As a result, the upper end position of the first pillar on the first wall surface portion is fixed, and the upper end position of the second pillar on the first wall surface portion sandwiched between the pair of first pillars is also naturally fixed and fixed.

Next, the second wall surface portion is provided on the connector via the connector installed on the first wall surface portion. In forming the second wall surface portion, the first plate portion of the connector and the lower receiving groove portion of the first pillar of the second wall surface portion are fitted, and the lower side surface of the first pillar is the vertical portion of the connector. Attach it in contact with. Then, the lower side surface of the second pillar of the second wall surface portion is brought into contact with the vertical portion of the connector. Like the first wall surface portion, the second wall surface portion has a mode in which the second pillar is sandwiched between the first pillars, and it is easy to erect a plurality of the second wall surface portions in order from the end side in the longitudinal direction of the foundation portion. The alignment of the upper and lower ends of the columnar member, which is a constituent material, is easier and the workability is improved.

Since the connector is in a mode in which only the first pillar of the second wall surface portion is fitted to the first plate portion, the second pillar of the second wall surface portion does not need to be fitted to the first plate portion, and the work is performed. The time and effort can be reduced. Further, since it is not always necessary to form the lower receiving groove portion on the second pillar of the second wall surface portion, the labor and cost of the same processing are not required (note that the lower receiving groove portion formed on the second pillar is used. It does not exclude aspects).

Further, when an anti-termite moisture-proof sheet material having anti-termite and moisture-proof ability is arranged so as to cover the lower surface and the lower end surface of the side surface of the first wall surface portion, termites invade the inside of the first wall surface portion. It is possible to prevent the lower portion of the first wall surface portion from being corroded due to the infiltration of water. In addition, since it is a sheet material, it is possible to proceed with the construction without waiting for impregnation and drying unlike a coating agent.

Further, when the termite-proof and moisture-proof sheet material is also arranged between the lower receiving groove portion and the connecting portion in the lower receiving groove portion of the first wall surface portion, the first wall surface portion is provided via the lower receiving groove portion. It is possible to further suppress the invasion of termites into the inside of the wall and the corrosion of the lower part of the first wall surface portion due to the infiltration of water. In addition, since it is a sheet material, it is possible to proceed with the construction without waiting for impregnation and drying unlike a coating agent.

To achieve the above object, the wooden building of the present invention includes a building foundation, at least three side walls, and a roof, and the building foundation is a concrete foundation provided at least below each side wall. The structure has a main body portion and a connecting portion formed so that a plate-shaped vertical surface portion erected from the foundation main body portion substantially coincides with the formation direction of each side wall, and each side wall is a shaft. It has a plurality of wooden columnar members whose lower portions are continuously arranged and arranged along the connecting portion, and a connecting structure portion for connecting the adjacent columnar members. It is a structure, and the roof is provided so as to cover the upper part of the inner region surrounded by each of the side walls.

Here, by providing the above-mentioned building foundation, side wall and roof, the wooden building can obtain a covered wooden building having an open side as an entrance / exit. The wooden building can be suitably used as a space for a house, a store, a garage, a storeroom, or the like. It is preferable to dispose a closing member such as a shutter or a door at the above-mentioned entrance / exit. In this case, a partial side wall such as a hanging wall or a sleeve wall may be provided around the closing member.

By having the above-mentioned foundation main body, the building foundation can support the load of the building including the side wall and the roof. It should be noted that the foundation main body is minimally configured to be provided at a position below each side wall, but for example, an embodiment including a portion constituting the floor inside the building together with the above position (so-called cloth foundation, solid foundation, soil floor, etc.) Concrete) is preferable.

The building foundation has the above-mentioned connecting portion, and the work of arranging a plurality of columnar members in a continuous linear arrangement along the lower part of the columnar member is performed by an unskilled worker. However, it can be done accurately and easily. The connecting portion is preferably continuous in a band shape, but is not limited to this, and is, for example, an embodiment in which a plurality of connecting portions having a predetermined length are intermittently arranged in the longitudinal direction. May be good.

Since the side walls are provided on at least three sides, the structure has a side wall in the back direction in a wooden building and side walls located on both sides of the side wall in the same back direction, and one side without a side wall (one open side) is an entrance / exit. Become. As described above, it is preferable to arrange a shutter or the like at the entrance / exit. For example, a side wall is provided on a part of the entrance / exit side, and a door or the like is also installed on the same side wall (that is, the side walls are provided on all sides). It may be in the above-mentioned aspect.

Each side wall can form a wall structure in a wooden building by continuously erecting a plurality of columnar members on the building foundation and connecting adjacent columnar members by a connecting structure portion. With this structure, for example, the wall surface structure can be provided even in a narrow place where it is difficult to carry in a large panel constituting the wall surface. As described above, examples of the "connecting structure portion" include screw bolts and the like. Further, as the columnar member, a prism having a quadrangular cross-sectional shape or the like is preferably used, but as described above, a columnar or the like having a circular cross-sectional shape may be used.

The roof divides the indoor and outdoor areas, and can protect the stored items indoors from rain, snow, sunlight, and outside air. The "roof" may be, for example, a structure made of a single or a plurality of boards made of a metal material, wood, a stone material, or a synthetic resin material. In this case, since the structure is relatively simple, construction is easy, and because it is plate-shaped, the structural weight of the roof is relatively light, and it is caused by the roof when a horizontal load is generated due to vibration such as an earthquake. Therefore, the force applied to each side wall can be reduced.

As will be described later, each of the side walls and the roof described above may be covered with a weather-resistant plate material on the outer surface thereof, or a coating agent may be applied to add weather resistance to the building. May be.

Since the wooden building of the present invention uses wood for the side wall that occupies most of the skeleton, it exhibits a carbon storage effect caused by the material and an energy saving effect by reducing the energy generated in the production of building materials.

Further, the wooden building of the present invention has a structure in which a plurality of wooden columnar members having side walls are connected to each other, and uses a large panel that constitutes a wall surface like a general building of the same type such as a garage. do not. For this reason, it is suitable for construction in a land in a narrow alley away from the main road where it is difficult for a vehicle loaded with a large panel or a crane vehicle to suspend it to enter, or in a relatively narrow land where houses are built around. Further, since the work of forming the side wall is an embodiment in which a plurality of columnar members are continuously arranged in a straight line so that the lower portion of the columnar member is aligned with the connecting portion, the columnar member which is a constituent material is arranged. The position of the upper end and the lower end is easy, and the side wall can be constructed without using a panel body or a crane, which is also good in workability.

When adopting the same type of side wall structure (side wall made by erection of multiple wooden columnar members) in a general wooden building, a foundation is placed on the foundation and the upper surface of the foundation and the lower surface of the pillar material are tenoned. However, since a large number of mortises are formed on the upper surface of the base, the strength of the base (particularly the load bearing capacity in the horizontal direction) is significantly reduced. However, since the wooden building of the present invention has a structure that does not use a base having a large number of mortises formed on the upper surface, it has a more robust structure than the general wooden building described above.
That is, the wooden building of the present invention has a carbon storage effect and an energy saving effect, has good workability in a relatively narrow land, and has a robust structure.

Further, the connecting portion uses a vertical portion corresponding to a vertical surface portion, a long L-shaped angle material having a horizontal portion bent from the lower end edge portion of the vertical portion, and the same L-shaped angle material as the foundation main body portion. Each columnar member is composed of anchor bolts to be fixed, and each columnar member has a lower receiving groove portion formed on the bottom surface in which a vertical surface portion is accommodated. When the structure is such that the vertical surface portion is fitted to each lower receiving groove portion and the building foundation and the side wall are connected, the workability is further improved.

Specifically, since the connection part has a simple structure in which an L-shaped angle material is placed on the foundation body part and fixed with anchor bolts, the work of providing the connection part on the foundation body part is easier. It has become. At the time of installation, the horizontal portion of the L-shaped angle material is a portion that abuts and is fixed to the foundation main body portion, and the vertical portion is a vertical surface portion. Further, the anchor bolt is inserted into, for example, a hole formed through the horizontal portion in the plate thickness direction, and the shaft portion embedded in the foundation main body forms a fixing structure with the foundation main body.

Furthermore, with the configuration of this connection part, the material cost can be reduced because the material is easy to procure, and the work can be easily performed even by an unskilled worker, so that it is easy to procure the number of workers. Labor costs can also be reduced, and as a result, construction costs can be further reduced.

Then, according to the configuration of each side wall portion by each columnar member described above, the erection of the columnar member is as simple as fitting the vertical portion of the connection portion provided on the foundation main body portion and the lower receiving groove portion of the columnar member. It is a work, and since it is performed in order from the end side in the longitudinal direction of the foundation main body along the vertical part, it is easy to erect a plurality of columnar members, and it is easy to align the upper and lower ends thereof. Workability is further improved.

In addition, the connecting portion has a vertical portion corresponding to a vertical surface portion, a horizontal portion bent from the lower end edge portion of the vertical portion, and one side end edge is fixed to the vertical portion and is positioned downward in use. It has a plate portion in which the side edge is fixed to the horizontal portion and the plate surface intersects the vertical portion, and the plate portions are provided at a plurality of locations at predetermined intervals. It is composed of a long angle material and anchor bolts that fix the angle material to the main body of the foundation. The same includes the second pillar arranged sandwiched between the first pillars, the first pillar and the lower side surface of the second pillar and the vertical portion are brought into contact with each other, and the plate portion is fitted into the lower receiving groove portion. When the structure is such that the second pillar is sandwiched between the first pillar and the building foundation and the side wall are connected, the workability is further improved.

Specifically, the horizontal part of the angle material is the part that abuts and is fixed to the foundation body part, and the vertical part is the vertical surface part. Further, since the plate portion is fixed to the vertical portion and the horizontal portion, the rigidity is improved so that the space between the vertical portion and the horizontal portion does not easily expand. Furthermore, the anchor bolt is inserted into, for example, a hole formed through the horizontal portion in the plate thickness direction, and the shaft portion embedded in the foundation main body forms a fixing structure with the foundation main body.

That is, according to the connection portion described above, the work of providing the connection portion on the foundation main body portion can be performed more easily. In addition, with this connection part configuration, it is possible to reduce material costs because it can be easily formed with materials that are easy to procure, and it is easy to procure workers because even unskilled workers can easily perform the work. As a result, labor costs can be reduced, and as a result, construction costs can be further reduced.

Then, in forming the side wall, the plate portion of the connection portion provided on the foundation portion and the lower receiving groove portion of the first pillar are fitted, and the lower side surface and the vertical surface portion of the first pillar and the second pillar are contacted with each other. By making the second pillar in contact with the first pillar and sandwiching the second pillar between the first pillars, it is easy to erect a plurality of pillars in order from the end side in the longitudinal direction of the foundation portion, and the upper and lower ends of the columnar members as constituent materials are aligned. Is easy and workability is further improved. In addition, the workability is good in that the side wall can be constructed without using a panel body or a crane.

Further, since only the first pillar is fitted to the plate portion instead of all the columnar members, the second pillar does not need to be fitted to the plate portion, and the labor of work can be reduced. Further, since it is not always necessary to form the lower receiving groove portion on the second pillar, the labor and cost of the same processing are not required (note that the mode in which the lower receiving groove portion is formed on the second pillar is excluded. is not).

Further, the roof is composed of a plurality of wooden shaft-shaped members horizontally laid near the upper ends of a pair of opposite side walls of each side wall, and the adjacent shaft-shaped members are connected by a connecting structure portion and the roof. When the side wall is rigidly or quasi-rigidly joined, the use of wood for the roof further improves the carbon storage effect and the energy saving effect.

Furthermore, since the roof can be formed with the same material and construction method as the side wall, the workability in a relatively narrow land is good. Furthermore, since the roof is rigidly or quasi-rigidly joined to the side wall, the building frame (the part located on the building foundation) has a so-called monocoque structure, and the robustness of the building is further enhanced.

The shape of the shaft-shaped member is not particularly limited, and examples thereof include a prism having a quadrangular cross-sectional shape and a cylinder having a circular or elliptical cross-sectional shape. Further, the shaft-shaped member has a recess such as a groove formed on one surface thereof, a convex portion such as a ridge is formed in the opposite direction of the concave portion across the long axis of the coaxial member, and the above-mentioned concave portion and the convex portion are fitted. It may have a structure in which adjacent shaft-shaped members are connected by being combined.

Further, when the foundation main body has a floor slab structure or an earthen concrete structure, the structure consisting of the side wall and the building foundation becomes a so-called monocock structure, and the robustness of the building is further enhanced. In addition, when the roof is formed of the same material and construction method as the side wall and has a structure rigidly or quasi-rigidly joined to the side wall, the structure consisting of the roof, the side wall and the building foundation becomes a monocock structure, and the side wall and the side wall and the building foundation are formed. It is a more robust structure than the structure consisting of the building foundation.

Further, if each side wall and roof, or one of each side wall or roof is covered with a weather resistant plate material on the outer surface thereof, weather resistance can be added to the building. Furthermore, the surface of the side wall (and the roof if the roof is made of wood) can be prevented from losing weight due to rain and snow or drying.

In order to achieve the above object, the method of constructing a wooden building of the present invention is to provide a concrete foundation main body at least at a position below the side wall to be formed, and to stand up from the foundation main body in a plate shape. A plurality of connecting portions including the vertical surface portion are provided on the building foundation forming step and the building foundation formed by the building foundation forming step, in which the connecting portion including the vertical surface portion is provided so as to substantially coincide with the planned formation direction of the side wall on the foundation main body portion. The side wall forming step and the side wall forming step of erection of the wooden columnar members of the above in a vertical axis, the lower part thereof is continuously aligned and arranged along the connecting portion, and the adjacent columnar members are connected. It comprises a roof forming step of providing a roof covering an inner region surrounded by a side wall formed by the forming step.

Here, according to the building foundation forming process, a concrete foundation main body can be provided at least at a position below the side wall.

It further suppresses the invasion of termites and the corrosion of the lower part of the side wall 3 due to the infiltration of water. The sheet material 23 can be impregnated like a coating agent and can be constructed without waiting for drying.

Roof 4 divides indoors and outdoors, and protects indoor storage items (vehicles, etc.) from rain, snow, sunlight, outside air, etc. Further, the roof 4 can be formed of the roof 4 by the same material and construction method as the side wall 3, and even an unskilled worker can perform the roof 4 accurately and easily. Furthermore, in the wooden building 1 in which the roof 4 and the side wall 3 are quasi-rigidly joined, the building frame has a monocoque structure, and the robustness is further improved.

The siding board and galvalume steel plate covered on the outer surfaces of the side wall 3 and the roof 4 add weather resistance and fire resistance to the wooden building 1 and improve the aesthetics. In addition, the surfaces of the side wall 3 and the roof 4 of the wooden building 1 are prevented from being thinned by rain and snow or drying. Furthermore, due to the addition of fire resistance, for example, when a wooden building 1 constructed in an urban area or the like is close to an adjacent building, even if the adjacent building catches a fire, it is suitable for the adjacent building. The wall surface on the side where it was located has a structure that makes it difficult for the fire to spread. Regarding "fire resistance", depending on the location, etc., "fire resistance" outer surface covering material with the ability to block fire heat shorter than "fire resistance", or "fire resistance" or less and "fire resistance" or higher It can also be replaced with a "quasi-fire resistant" exterior covering material that has the ability to block the heat of the fire.

Since the connection between the building foundation 2 and the side wall 3 is the above-mentioned connection structure, the wooden building 1 has better workability and a robust structure as compared with the above-mentioned general wooden building, and in addition, it has a robust structure. Since the roof 4 and the side wall 3 are quasi-rigidly joined, the building frame has a monocock structure, further improving the robustness.

Since the wooden building 1 uses wood for the side wall 3 and the roof 4 which occupy most of the skeleton, it exhibits a carbon storage effect caused by the material and an energy saving effect by reducing the energy generated in the production of building materials. Further, standard (general-purpose and same standard) wood is used for the columnar members 35 and 36 constituting the side wall 3 and the shaft-shaped members 41 and 42 constituting the roof 4, and the upper and lower end faces are appropriately used. Since it is processed and used, material costs can be reduced because it is easy to procure.

Further, the wooden building 1 is formed by connecting a plurality of wooden columnar members 35, 36 on which the side wall 3 is erected, and is connected by a plurality of wooden shaft-shaped members 41, 42 on which the roof 4 is laid. It is composed of standard wood, and does not use large panels that make up the wall surface like general buildings of the same type such as garages. For this reason, it is suitable for construction in a land in a narrow alley away from the main road where it is difficult for a vehicle loaded with a large panel or a crane vehicle to suspend it to enter, or in a relatively narrow land where houses are built around. Furthermore, as described above, a plurality of joint structures of the side wall 3 and the building foundation 2 are erected in order from the end side in the longitudinal direction of the building foundation 2 while fitting the connecting portion 22 and the columnar members 35 and 36. Moreover, since it is formed by connecting adjacent columnar members 35 and 36, it is easy to align the upper ends and lower ends of the columnar members 35 and 36, and the side wall 3 can be configured without using a panel body or a crane. In terms of points, the workability is good.

As described above, the wooden building 1 has a carbon storage effect and an energy saving effect, has good workability in a relatively narrow land, and has a robust structure.

In the present embodiment, the building is a one-story building, but the building is not limited to this, and may be two stories or more. In this case, a structure may be provided in which a bearing structure such as a steel column or a bearing wall is provided on the indoor side of the side wall 3.
