Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a structural skeleton of a wooden building formed by combining a wooden column and a wooden beam, and in particular, a relative deformation is restrained at a joint between the column and the beam, and a bending moment between the two is restricted. The present invention relates to a wooden building structure frame used as a ramen frame structure in which transmission occurs.
[0002]
[Prior art]
In a wooden building that has been widely used since ancient times, a pillar and a beam are joined by inserting a tenon in which the end of the beam is processed into a tenon provided in the pillar. In such a joint structure, deformation between both is allowed, and no bending moment is transmitted. In other words, it cannot withstand the bending moment, and a frame formed by a plurality of columns and a plurality of beams (including members that are erected in the lateral direction such as a girder, a girder, a base, etc.) is deformed. easy. For this reason, a brace is arranged in the wall between the columns, and it is resistant to deformation of the frame due to horizontal force during an earthquake or the like.
[0003]
Brace is generally provided between a plurality of columns and is required in two orthogonal directions. Therefore, in a conventional wooden building, it is necessary to secure a wall for providing a brace, which may hinder the setting of an opening or the use of an indoor space. Under such circumstances, a proposal has been made in which a column and a beam are formed as a so-called rigid connection, that is, a connection in which a bending moment is transmitted, and a frame is a rigid frame structure. For example, JP-A-8-246561, JP-A-2000-265553, and JP-A-26553414 describe a joint structure between a column and a beam having a rigid frame structure.
By using the joint structure as described above to make the wooden frame into a rigid frame structure, bracing can be reduced or unnecessary, and the degree of freedom in design is greatly increased.
[0004]
[Problems to be solved by the invention]
However, the above-described conventionally-known joining structures have the following unsolved problems.
The structures described in JP-A-8-246561, JP-A-2000-265553, and JP-A-26553414 are all joined by abutting an end face of a beam to a side surface of a pillar. And the beam is joined to the side surface of the pillar from two directions. In other words, the two-way ramen structure is integrated via the pillar to constitute the entire structural body. As described above, when a beam in two directions is joined to one column, the structure of the joint between the beam and the column becomes complicated, and the amount of cross-section loss due to the processing of the column increases. For this reason, when a large bending moment is transmitted from the beam, it may be a structural weak point. In order to avoid such structural weaknesses, the cross section of the column must be enlarged. However, if a column having a large bending rigidity in two directions is adopted, the cross-sectional dimension becomes large, and corners in a living room, etc. The pillars protrude from the room, which hinders the use of the living room.
[0005]
The present invention has been made in view of the above circumstances, and an object thereof is to join a column and a beam so that bending moment can be transmitted, and reduce or eliminate the number of braces as a ramen structure. It is also an object of the present invention to provide a wooden building structure that enables effective use of indoor space without excessively increasing the cross-sectional dimensions of pillars.
[0006]
[Means for Solving the Problems]
In order to solve the above problem, the invention according to claim 1 has a plurality of rigid frame structures formed by joining a wooden beam and a plurality of wooden columns so that a bending moment can be transmitted, and at least two There is provided a wooden building structural body, wherein the ramen frame structures are joined to each other so that the directions of the uprights including the axis of the ramen frame structure are different.
[0007]
In the above configuration, it is preferable that the wooden beam and the pillar have a member size in the vertical plane including both axes larger than the member dimension in the thickness direction with respect to this plane. That is, the effect of the present invention becomes more remarkable by increasing the dimension of the member in the direction in which the bending moment acts when the beam and the column are joined to form the rigid frame structure.
[0008]
This structural frame shall have a structure in which each frame structure has one beam and a plurality of columns, and can withstand a vertical load and a horizontal load acting in parallel with an elevation including these axes. Has become. However, it does not have a large resistance to the horizontal force perpendicular to the vertical surface. However, ramen frames that can independently resist horizontal force in one direction are combined in different directions, and these are joined, so that each ramen frame is shared and resists horizontal force, It is a structural body that can effectively resist horizontal forces in all directions. In addition, each frame structure may have a structure capable of resisting a horizontal force and a bending moment in one direction, and the structure of the joint between the beam and the column can be simplified and firmly joined. Furthermore, the beam and the column only need to resist the bending moment in one direction, and a member having a large bending rigidity in only one direction can be used without increasing the cross section.
[0009]
The invention according to claim 2 is the wooden building structure according to claim 1, wherein the ramen frame is joined by placing a wooden beam on an upper end surface of the wooden pillar. Are joined by connecting the wooden beams to each other.
[0010]
In this structural body, a plurality of ramen frames are connected to each other by beams, and horizontal force is transmitted between the frames via the beams. When the beam is joined to the column, a force and a bending moment perpendicular to the end face mainly act on the joint end face. Therefore, it is possible to prevent a large bending moment and a shear force from simultaneously acting on the joint end face, and to simplify the joint structure. Further, since the frame structures are connected by joining the beams, the position of the pillars can be freely set, and the degree of freedom of using the indoor space is increased.
[0011]
The invention according to claim 3 is the wooden building structural body according to claim 2, wherein the wooden beam of the ramen frame has a portion projecting outward from a position joined to the plurality of wooden columns, It is assumed that the tip end surface of the protruding portion is joined to the side wall of the wooden beam of the other ramen frame structure.
[0012]
In this structural frame, even when the position of the column is restricted, each frame structure can surely resist horizontal force. Then, the structure can be easily connected to the other ramen frame structures, can transmit the horizontal force between each other, and can resist the horizontal force in all directions as a whole.
[0013]
According to a fourth aspect of the present invention, in the wooden building structure skeleton according to the first, second or third aspect, the wooden pillar and the wooden beam are formed of an elevation including an axis of the ramen frame. The member cross-sectional dimension in the in-plane direction is set to be larger than the member cross-sectional dimension in the direction perpendicular to the upright surface, and the wooden pillar and the wooden beam have substantially the same member cross-sectional size in the perpendicular direction to the upright surface. It is assumed that
[0014]
Each of the ramen frames of this structural frame has a large resistance to bending moments acting in the vertical plane including the axes of the beams and columns constituting the frames, and has an angle with respect to the vertical plane. The bending moment acting in the direction having the resistance is resisted by the other rigid frame structures. Therefore, the dimension of the member in the thickness direction with respect to the vertical surface can be reduced. Therefore, it is possible to prevent the pillar from projecting at a corner or the like of the living room. In addition, even if the dimensions of the members are large in the above-mentioned vertical plane, since the member dimensions in the thickness direction of the columns and beams are the same, the columns and beams form part of the outer wall or partition wall of the building. By doing so, there is little hindrance to the use of the indoor space.
[0015]
The invention according to claim 5 is characterized in that a wooden beam having an axis in the long axis direction of the cross section is joined on a wooden column having a flat cross section so as to be placed between the wooden column and the wooden beam. A plurality of rigid frame structures capable of transmitting a bending moment are provided, and wooden beams of at least two rigid frame structures are connected so that their height positions are aligned and the directions of axes of the wooden beams are different from each other. The present invention provides a wooden building structure skeleton characterized in that:
[0016]
In this structural skeleton, at least two wooden beams are connected to each other so that a horizontal force during an earthquake or the like is transmitted. Each of the wooden beams is rigidly connected to the wooden column to form a ramen structure, and resists a bending moment acting in an elevation including the axis of the wooden beam and the wooden column. Therefore, each horizontal frame in any direction has a sufficient resistance only to the horizontal force and bending moment in one direction, but a plurality of vertical frames have the horizontal force and the bending force. The components in the respective directions of the bending moment are shared, and the structural body as a whole can resist horizontal forces and bending moments in all directions.
In addition, the wooden beam and the wooden pillar may be members having a large resistance to a bending moment in one direction, and it is not necessary to increase the cross-sectional dimension in the direction perpendicular to the elevation including these axes. Also, the joint between the wooden beam and the wooden pillar may transmit the bending moment in only one direction, and the structure can be simplified.
In addition, what is necessary is just that the said ramen frame structure has one beam and at least one pillar.
[0017]
According to a sixth aspect of the present invention, in the wooden building structure skeleton according to the fifth aspect, the cross section of the wooden beam has a member size in a lateral direction substantially equal to a member size in a short side direction of the wooden pillar. The member size in the height direction of the cross section of the wooden beam is larger than the member size in the lateral direction.
[0018]
In this structural frame, the wooden beam and the wooden column have the same dimensions in the thickness direction of the frame structure formed by them, and these can be used as a part of the wall. This makes it possible to effectively use the room space without protruding a part of the pillar into the room.
[0019]
According to a seventh aspect of the present invention, in the wooden building structure skeleton according to the second or fifth aspect, two of the plurality of ramen frames joined to each other form an outer wall of the building. The wooden beams of both the frame structures are joined to each other at the tip of a portion projecting from a position joined to the wooden pillar, and the lower part of the two projecting portions serves as an opening of the building. Shall be.
[0020]
Generally, in a wooden building, it is difficult to construct an overhang such as a veranda or a large eave. In particular, it is common to use through columns at one or more floors at the corners of a building having two or more floors, that is, at the corners of the building, and it is difficult to provide a continuous large opening at the corner of the building. However, in this structure, a wooden beam and a wooden column constitute a ramen frame structure, and a beam projecting from the column position protrudes from two directions to form a protruding corner, so that the lower portion is continuous on two surfaces. An opening can be easily provided.
[0021]
The invention according to claim 8 is the wooden building structure according to claim 4, 5, or 6, wherein the wooden pillar or the wooden beam is parallel to an elevation including an axis of a ramen frame structure. The side surfaces of the members are exposed in the living room of the building and are part of the wall surfaces.
[0022]
The wooden beam and the wooden column resist a large bending moment in a direction parallel to the elevation including the axis thereof. For this reason, the side surfaces of the wooden beams and wooden pillars are large, but the side surfaces can be finished smoothly and used as a part of the interior surface. This provides a good woody living room environment.
[0023]
According to a ninth aspect of the present invention, in the wooden building structure skeleton according to any one of the first to eighth aspects, a joint structure between a wooden pillar and a wooden beam of the ramen frame has a predetermined distance from the wooden beam. A screw member having a helical projection on the outer periphery is screwed into two vertical holes provided with an opening, and a column fixing bracket is provided at each of both ends in the column width direction at the end of the wooden column. The center of the end face of the wooden pillar in the pillar width direction is in contact with the upper or lower surface of the wooden beam, and the upper end or lower end of the screw member is connected to the pillar fixing bracket. Shall be.
[0024]
In this structural skeleton, the bending moment and the vertical force are reliably transmitted at the joint between the wooden pillar and the wooden beam, and high rigidity is maintained. That is, the upper end surface or the lower end surface of the column is directly in contact with the lower surface or the upper surface of the beam, and a vertical force is transmitted as a supporting force. On the other hand, when the bending moment is applied, the column fixing bracket fixed to the both ends transmits a force as a compressive force or a tensile force in the axial direction of the column from the screw member penetrating the wooden beam, thereby forming the column with the column. A bending moment is transmitted to and from the beam. At this time, most of the force acting on the column fixing bracket is a couple due to the bending moment, so that the column fixing bracket and its mounting portion can have a simple structure.
[0025]
Further, the screw member penetrates in the vertical direction of the wooden beam, that is, in the direction perpendicular to the grain, and has an effect of reinforcing the beam. The screw member has a helical overhang of the peripheral surface fixed to the wooden beam over the entire length, and the force is transmitted over a wide range in the cross section of the beam. Therefore, stress is less concentrated in the beam, and the bending moment is smoothly transmitted.
[0026]
According to a tenth aspect of the present invention, in the wooden building structure skeleton according to any one of the first to eighth aspects, a joining structure between a wooden beam of the ramen frame and a wooden beam of another ramen frame, A screw member having a helical bulge and a lateral screw hole or a through hole in its peripheral surface is screwed into a vertical hole formed in the first wooden beam, and a side surface of the first wooden beam. A beam joint fitting is fixed to a side surface of the first wooden beam by a bolt inserted into a lateral hole reaching from the screw member and screwed into the screw hole, or a bolt inserted into the lateral hole and the through hole. It is assumed that the beam joint and the second wooden beam are connected.
[0027]
In this structural skeleton, at the joint between the wooden beams, the vertical force and the horizontal tensile force acting from the second wooden beam are transmitted to the screw member by bolts via the beam joint fittings. . The force transmitted to the screw member is transmitted from the peripheral surface of the screw member to the beam in which the screw member is embedded. Therefore, even if a large shearing force acts on the joint between the beams, the force is smoothly transmitted, and a large local stress is rarely generated. Further, the screw member can also be used as a screw member for joining the beam and the column, and the structure of the portion for joining the column and the two beams can be simplified.
[0028]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a schematic perspective view showing a wooden building structure skeleton which is one embodiment of the invention according to the present application.
This structural body is formed by combining a plurality of rigid frame structures in which a wooden column (hereinafter, referred to as a column) and a wooden beam (hereinafter, referred to as a beam) are joined so that bending moment can be transmitted. That is, a single frame structure is formed by the beam 21 arranged in the X direction and the two columns 11 and 12 supporting the same, and the beam 22, the two beams, and the two columns 13 and 14 are arranged in parallel. Thus, one frame structure in the X direction is formed. Further, in the Y direction, a single frame structure is formed by the beam 23 and the two columns 15 and 16, and a single frame structure is formed by the beam 24 and the columns 17 and 18.
[0029]
These ramen frames have a so-called beam winning structure in which a beam is mounted on a pillar, and the height of the beams is uniform in all ramen frames. Then, the columns and beams are so arranged that each frame structure can independently resist a horizontal force acting in the axial direction of the beams or a bending moment acting in a vertical vertical plane including the axes of the beams and columns. Are joined. The columns and beams constituting the ramen frame structure are flat members having a large cross-sectional dimension in a direction parallel to an elevation including these axes and a small cross-sectional dimension in a direction perpendicular thereto. Therefore, each of the rigid frame structures has a large resistance to the horizontal force and bending moment in the vertical plane including the axis of the beam and the column, that is, the axis of the rigid frame structure, but the horizontal force perpendicular to this. Etc. have little resistance. For example, a rigid frame structure composed of two columns 11, 12 and a beam 21 has a large horizontal force and a large bending force acting in a vertical plane in the X direction, and has a large horizontal resistance in the Y direction. It hardly resists forces and bending moments.
[0030]
These ramen frame structures are connected to each other by joining a beam and a beam supported on a column, and the beam and the beam are joined so as to transmit a horizontal force and a vertical shear force. I have. Therefore, the ramen frame structure is divided into components in the X and Y directions and resists the horizontal force acting in an arbitrary direction acting at the time of an earthquake, etc., and can resist the horizontal force in all directions as a whole. Has become.

【The invention's effect】
As described above, the wooden building structure skeleton according to the present invention includes a plurality of rigid frame structures in which wooden beams and wooden columns are connected to each other so that bending moments can be transmitted, and these are connected in different directions to form a structural frame. Therefore, each of the frame structures independently resists a horizontal force and a bending moment in one direction. Therefore, the joint between the column and the beam of each frame structure only needs to resist the bending moment in one direction, and the joint can be firmly connected with a simple structure. Each of the members can also have a reduced cross-sectional dimension in a direction perpendicular to the vertical plane including the axis of the ramen frame structure, and can be a building that can effectively use space.
In addition, the beams are joined so as to be placed on the columns, and the frames are connected by joining the beams to each other, so that the frames can be easily connected to each other. It can be set.
