  It is another object of the present invention to provide a wood-based frame structure capable of including a column as a wall quantity and a design method thereof.

  In order to achieve the above object, a wooden frame frame according to the present invention includes, as described in claim 1, a lower horizontal member, a wall column erected on the upper surface thereof, and a lower surface on the top of the wall column.

It is a thing.

  Further, the wooden frame frame according to the present invention includes a wall column side connection bolt that is screwed into a female screw formed at a connection side end of the wall column side fixing member, and the horizontal member. A horizontal member side connection bolt that is screwed into a female screw formed at the connection side end of the side fixing member, and a wall nut side connection bolt and a connection nut that pulls the horizontal member side connection bolt together. Is.

  Further, the wooden frame frame according to the present invention includes a wall column side connection bolt that is screwed into a female screw formed at a connection side end of the wall column side fixing member, and the horizontal member. A horizontal member side connection bolt that is screwed into a female screw formed at a connection side end of the side fixing member, and a wall nut side connection bolt and a connection nut that pulls the horizontal member side connection bolt together. In addition, the second connecting mechanism includes a wall column side connection bolt that is screwed into a female screw formed at a connection side end of the wall column side fixing member, the wall column side connection bolt, and the anchor bolt.

  In the wooden frame frame according to the present invention, a predetermined earthquake resistant wall is installed between the upper horizontal member and the lower horizontal member, or between the upper horizontal member and the fabric foundation.

  In the wooden frame frame according to the present invention, the plate members belonging to each plate group are obliquely crossed with each other in two sets of plate members in which the earthquake-resistant wall is arranged in a plurality so that the plate members having a predetermined width are parallel to each other. A rectangular scratch panel that is laminated in such a manner, two pipe columns to which both side edges of the scratch panel are fastened, an upper horizontal member to which the upper edge is fastened, and a lower edge are fastened It is composed of a lower horizontal member or a foundation.

  In addition, the design method of the wooden frame frame according to the present invention includes a wall magnification of the wall column and a wall magnification of the seismic wall when designing an allowable stress level with respect to an earthquake load in the wooden frame frame according to claim 6. Is added.

  In order to solve the above-mentioned problems, the applicant of the present invention firstly has a rigid connection at a joint such as a column and beam or a column and a base so that a frame using a wooden column or beam as a frame member can be regarded as a ramen frame. As a result of diligent research focusing on how to increase the degree, we have obtained industrially very useful knowledge that if the joint location is configured as in the present invention, it is possible to secure a rigid degree that can be regarded as ramen. .

  Next, the Applicant has conducted research focusing on whether the wall column of the present invention that constitutes the ramen frame can be included in the wall quantity, and here again, the engineering validity of including the wall column in the wall quantity is also considered. To get sex.

  By the way, the pillars that make up the ramen frame are basically not included in the wall quantity. That is, the bearing wall generally has a width-to-height relationship of within 1: 3, and if the height is 2,730 mm, a width of 910 mm is required, and the height is 3 m. For example, a width of 1 m is required.

  In contrast, column widths are usually smaller than walls. For this reason, it has been impossible in the past to include the column in the wall amount. This is because when a horizontal force is applied to an elongated member during an earthquake, the bending deformation is generally superior to the shear deformation and tends not to act as a shear resistance member. The limitation of the relationship comes from this point.

  In addition, the restoring force characteristics of columns and seismic walls, which are the elements that make up a rigid frame, are greatly different. For example, seismic walls mainly composed of braces are connected to beams and columns. The initial stiffness tends to be small due to the presence of slight play, so it was said that the restoring force characteristics of the elements that make up the rigid frame and the restoring force characteristics of the seismic wall cannot simply be superimposed. .

  However, according to the present invention, the applicant has proved through experiments that a wall column of 910 mm or less can be regarded as a seismic wall, and that the restoring force characteristics can be superimposed on the conventional seismic wall. As a result, we succeeded in constructing a conventional frame structure with a ramen frame, and also found the engineering validity of including the wall columns of the ramen frame together with other seismic walls. is there.

  Needless to say, this finding greatly improves the degree of freedom in design.

  In the wooden frame frame according to the present invention, the wall column is formed in a rectangular cross section, and the longitudinal direction thereof is arranged so as to coincide with the material axis direction of the lower horizontal member or the upper horizontal member. Wall pillar side fixing member that is provided with a notch in each of the four projecting corners located at the top and is inserted and fixed in a wall column side fixing hole drilled in parallel with the column axis direction of the wall pillar from the inner surface of the notch Insert and fix in the horizontal member fixing hole or horizontal member fixing hole drilled in parallel with the column axis direction of the wall column from the upper surface of the lower horizontal member facing the inner surface of the notch or the lower surface of the upper horizontal member. The horizontal member-side fixing member is connected through a connecting mechanism having a drawing function.

  According to this configuration, by operating the connecting mechanism to draw the wall column side fixing member and the horizontal member side fixing member toward each other, the abutting end surface of the end surface of the wall column excluding the notched portion is located on the lower side. The upper surface of the frame member or the lower surface of the upper horizontal frame member is abutted against and strongly pressed, and there is no play at the joint location, particularly play against rotational deformation, and the rotational rigidity at the joint location is significantly improved.

  On the other hand, by operating the coupling mechanism and pulling the wall-column-side fixing member and the horizontal member-side fixing member toward each other, the shearing force due to the horizontal force during an earthquake is borne by the tensile resistance of the coupling mechanism, and thus the column The horizontal frame or the column and the base are rigidly connected, and the frame made by combining them is a ramen frame.

  When the wall pillar is a wall pillar on the first floor, the base is omitted, and the anchor bolt embedded in the RC foundation in advance and the wall pillar side fixing member may be connected via a connecting mechanism. .

  The horizontal member means a horizontal frame member such as a waistline, a girder, and a beam.

  The cutout is an arrangement space in which the coupling mechanism is arranged and a work space for operating it, but the shape is not limited. Specifically, a rectangular cutout can be considered.

  The wall column side fixing member and the horizontal member side fixing member may be anything as long as they are fixed to the wall column or horizontal member. For example, a screw member in which a spiral protrusion is wound around the peripheral surface of the rod. Can be adopted.

  The structure of the connection mechanism is arbitrary, but the wall column side connection bolt that is screwed into the female screw formed at the connection side end of the wall column side fixing member, except for the wall column base of the first floor, A horizontal member-side connection bolt that is screwed into a female screw formed at the connection-side end of the material-side fixing member, and a wall nut-side connection bolt and a connection nut that pulls the horizontal member-side connection bolt together. In the case of a wall column base on the first floor, the wall column side connection bolt that is screwed into the female screw formed at the connection side end of the wall column side fixing member, and the wall column It is possible to constitute the side connection bolt and the anchor bolt with a connection nut that pulls the side connection bolt and the anchor bolt together.

  Here, if a predetermined earthquake-resistant wall is installed between the upper horizontal member and the lower horizontal member, or between the upper horizontal member and the fabric foundation, it becomes a form in which the earthquake-resistant wall is added to the ramen frame. Is further improved.

  As the earthquake-resistant wall, for example, a rectangular shape formed by laminating a plurality of plate material groups in which a plurality of plate materials having a predetermined width are arranged in parallel with each other so that the plate materials belonging to each plate material group are obliquely crossed with each other. A tear panel, two tube pillars to which both side edges of the tear panel are fastened, an upper horizontal member to which the upper edge is fastened, and a lower horizontal member or foundation to which the lower edge is fastened It is possible to configure.

  When designing the allowable stress level for seismic load in a wooden frame frame including such a seismic wall, if the wall magnification of the wall column and the wall magnification of the seismic wall are added, the evaluation of the wall magnification is possible. It becomes rational, and even with a large opening, it is possible to ensure sufficient earthquake resistance.

The screw members 12, 12 are inserted and fixed by screwing.

  On the other hand, two anchor bolts 31, 31 are embedded in the fabric foundation 6, and their end portions project at positions facing the inner surfaces of the notches 11 a, 11 a.

  And the screw pillar 12 and the anchor bolt 31 are connected via the 2nd connection mechanism 14a which has a drawing function, and the wall pillar 7 of the 1st floor is rigidly contacted by the upper surface of the cloth foundation 6. FIG.

  As shown in FIG. 5, the connection mechanism 14 a includes a wall column side connection bolt 16 that is screwed into a female screw 15 formed at the connection side end of the screw member 12, an anchor bolt 31, and a wall column side connection bolt 16. And a connecting nut 19a for pulling the anchor bolts 31 toward each other.

  In addition, notches 11 and 11 are also provided at two projecting corners located at the top of the wall column 7, and the screw member 12 inserted and fixed to the wall column 7 and the screw inserted and fixed to the body holder 2. By connecting the member 13 with the connecting mechanism 14 having a pulling function, the wall column 7 is rigidly in contact with the lower surface of the trunk 2, but is upside down from the case of the leg portion of the wall column 3. Therefore, the description thereof is omitted here.

  Next, a procedure for rigidly connecting the wall column 3 to the body insert 2 using the coupling mechanism 14 will be described below.

  First, as shown in FIGS. 6 and 8 (a), the screw members 12, 12 are screwed into the two wall column side fixing holes 41, 41 drilled in parallel with the column axis direction of the wall column 3. Next, the wall column side connecting bolt 16 is screwed into the female screw 15 of the screw member 12.

  Here, as can be seen from the figure, the wall-column side connecting bolt 16 is threaded so as to be a positive screw on the column side from the center, and is threaded so as to be a reverse screw on the opposite side. The positive screw side is screwed into the female screw 15 and then fixed so as not to rotate.

  Next, the connecting nut 19 is screwed into the opposite end of the wall column side connecting bolt 16, that is, the reverse screw side.

  Here, the inner surface of the connecting nut 19 is internally threaded with a reverse screw so as to correspond to the opposite end of the wall-column-side connecting bolt 16 on the column side from the center, and a positive screw on the barrel insertion 2 side from the center. The female thread is cut.

  On the other hand, as shown in FIG. 7 and FIG. 8 (a), the screw member 2 is inserted into the two horizontal member fixing holes 42, 42 drilled in parallel with the column axis direction of the wall column 3 on the side of the body 2. 13 and 13 are inserted and fixed by screwing, and then the horizontal member side connecting bolt 18 is screwed into the female screw 17 of the screw member 13.

  Here, when the column 3 is erected, the horizontal member side connecting bolt 18 is screwed deeply so that it does not interfere with the wall column side connecting bolt 16 and the connecting nut 19 and then retracted. 20 is screwed.

  Next, as shown in FIG. 8 (b), the wall pillar 3 is erected on the upper surface of the trunk 2.

  Next, as shown in FIG. 8 (c), the horizontal member side connecting bolt 18 screwed into the screw member 13 on the barrel insertion 2 side is rotated in the reverse direction to screw the upper end thereof into the connecting nut 19.

  The horizontal member-side connecting bolt 18 is screwed into the connecting nut until the nut 20 screwed into the horizontal member-side connecting bolt 18 contacts the lower surface of the connecting nut 19.

  In this case, when the connection nut 19 is turned clockwise with respect to the horizontal member side connection bolt 18, the nut 20 serves as a stopper, so that the connection nut 19 is connected to the horizontal member side connection via the nut 20. Integrated with the bolt 18.

  Next, the connecting nut 19 is rotated clockwise with respect to the horizontal member side connecting bolt 18.

  In this way, the horizontal member side connecting bolt 18 is screwed into the female screw 17 of the screw member 13 on the barrel insertion 2 side, and the wall column side connecting bolt 16 is screwed into the wall column side connecting bolt 16 with a reverse screw. Thus, the screw member 12 fixed to the wall column 3 and the screw member 13 fixed to the trunk 2, and thus the wall column 3 and the beam 2 are attracted, and the central portion of the wall column 3 is drawn. Is strongly pressed against the upper surface of the torso 2.

  As described above, according to the wood-based ramen frames 1 and 5 according to the present embodiment, the screw member 12 that is the wall column side fixing member and the screw member 13 that is the horizontal member side fixing member via the coupling mechanism 14. Are brought into contact with the lower surface of the girder 4 and the upper and lower surfaces of the girder 2 and strongly pressed against each other. There is no play with respect to deformation, particularly rotational deformation, and the rotational rigidity at the joint is greatly improved.

  On the other hand, by pulling the screw member 12 and the screw member 13 together by the coupling mechanism 14, play in the vertical load direction is reduced, and the shearing force due to the horizontal force during an earthquake is borne by the tensile resistance of the coupling mechanism 14. Thus, the wall columns 3 and 7 and the girder 4 or the barrel 2 are rigidly connected, and the frame formed by combining them is a ramen frame.

  Further, according to the wood-based frame frame 5 according to the present embodiment, the screw member 12 and the anchor bolt 31 that are wall column side fixing members are attracted to each other via the connecting mechanism 14 a, so that the end surface of the wall column 7 The contact end surface excluding the notched portion is brought into contact with the fabric foundation 6 and pressed strongly, so that there is no play at the joint portion, especially the rotation deformation, and the rotational rigidity at the joint portion is remarkably improved.

  On the other hand, when the screw member 12 and the anchor bolt 31 are attracted to each other by the coupling mechanism 14a, play in the vertical load direction is reduced, and the shearing force due to the horizontal force during an earthquake is borne by the tensile resistance of the coupling mechanism 14a. Thus, the wall pillar 7, the torso 2, and the fabric foundation 6 are rigidly connected, and a frame formed by combining them becomes a ramen frame.

  In addition, according to the wooden frame frame 5 according to the present embodiment, the notch 11 and the notch 11a become a working space for operating the coupling mechanism 14 and the coupling mechanism 14a, and after the wall columns 3 and 7 are erected. However, good workability can be ensured.

  Although not particularly mentioned in the present embodiment, the configuration of the coupling mechanism is arbitrary, and the wall column side fixing member and the horizontal member side fixing member, or the wall column side fixing member and the anchor bolt can be drawn. Any configuration may be used.

  Although not specifically mentioned in the present embodiment, the inner surface of the notch and the lower surface of the upper horizontal member facing the notch or the upper surface of the lower horizontal member are fitted into the notch 11 and the notch 11a. Or you may make it provide the buckling prevention member comprised so that it might contact | abut to the upper surface of a fabric foundation.

  The buckling prevention members 51 and 51 shown in FIG. 9 are formed of a steel material having a shape obtained by vertically dividing a cylindrical body, and extend to a semi-cylindrical portion 52, a semicircular bottom plate 55 extending to the lower end thereof, and an upper end thereof. In addition to the semicircular top plate 53, the semicircular bottom plate 55 and the semicircular top plate 53 are formed with grooves 54 and 54 into which the horizontal member side connection bolt 18 and the wall column side connection bolt 16 are respectively fitted. It is.

  If the buckling prevention members 51, 51 are attached so that the horizontal member side connection bolt 18 and the wall column side connection bolt 16 are fitted in the grooves 54, 54, the wall column receives a bending moment in the construction surface. Then, a compressive force acts on either the left or right buckling prevention member 51, and it is possible to prevent local buckling from occurring due to an excessive compressive force flowing through the coupling mechanism 14.

(Second Embodiment)

  Next, a second embodiment will be described. Note that components that are substantially the same as those of the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

  FIG. 10 is an overall perspective view of a frame constructed by employing the wooden frame frame according to the present embodiment. As can be seen from the figure, the wooden frame frame 61 according to the present embodiment includes a torso 2 that is a lower horizontal member, a wall pillar 3 on the second floor standing on the upper surface thereof, and the top of the wall pillar. The wooden frame frame 65 is composed of a fabric base 6 and a first-floor wall column 7 erected on the upper surface thereof. In addition, the upper part of the wall pillar on the first floor is joined at the lower surface, and it is composed of a trunk 2 as an upper horizontal member that is bridged.

  Here, among the wooden ramen frame 61 and the wooden ramen frame 65, the structure related to the ramen is completely the same as that of the wooden ramen frame 1 and the wooden ramen frame 5, and the description thereof is omitted here.

  In the wooden frame frame 61 according to the second embodiment, a seismic wall 62 is installed between the girder 4 and the torso 2, and the wooden frame frame 65 has the seismic wall 63 in the torso 2 and the cloth foundation 6. It is installed between.

  As shown in FIG. 11, the earthquake resistant wall 63 is formed by laminating two sets of plate groups in which a plurality of plate members 71 having a predetermined width are arranged in parallel with each other so that the plate members 71 belonging to each plate group cross each other. A rectangular scratch panel 73, two pipe columns 72 and 72 to which both side edges of the scratch panel are fastened, and a torso 2 which is an upper horizontal member to which the upper edge is fastened And a base 64 to which the lower edge is fastened.

  The seismic wall 62 includes the same panel 73 as the seismic wall 63, two pipe columns 72 and 72 to which both side edges of the panel are fastened, and an upper horizontal frame to which the upper edge is fastened. It is comprised with the girder 4 which is material, and the trunk 2 as a lower horizontal member to which a lower edge is fastened.

  The tear panel 73 can be manufactured as a load bearing surface material in which a plate material 71 such as cedar is bonded with an adhesive in an oblique 45-degree lattice shape.

  The pipe column 72 can be fixed to the base 64 or the trunk 2 using a hole-down hardware.

  In designing such a wooden frame frame 61 and a wooden frame frame 65, when designing the allowable stress level for the seismic load, the wall magnification of the wall columns 3 and 7 and the wall magnification of the earthquake resistant walls 62 and 63 are calculated. to add.

  Previously, the column was not considered a seismic wall as mentioned above, and could not be included in the wall amount. However, as a result of the dynamic force test, it was engineeringly appropriate to include it in the wall amount. Sex was found.

  FIG. 12 shows the result of the dynamic force test.

  The figure shows the restoring force characteristics of only the wall column 7 in cases 2-1, 2-2, 2-3 (three test bodies), and the restoring force characteristics of only the seismic wall 63 in cases 3-1, 3-2. , 3-3 (three test bodies), the restoring force characteristics when the wall column 3 and the earthquake-resistant wall 63 are used in combination are shown as cases 1-1 and 1-2.

  The most important thing that can be understood from this test is that the restoring force characteristic when the wall column 3 and the earthquake-resistant wall 63 are used together is the restoring force property of only the wall column 7 until the interlayer deformation angle is around 0.015 to 0.02. And the restoring force characteristic of the seismic wall 63 alone can be evaluated.

  Considering that the interlayer deformation angle used in the allowable stress degree design is usually 1/150 to 1/120 (0.006 to 0.008), the above test result is the sum of the above with a sufficient margin. It shows that it is possible.

  As described above, according to the wood-based ramen frames 61 and 65 and the design method according to the present embodiment, the wall pillar 3 which is a constituent element of the ramen is obtained in addition to the same effects as described in the first embodiment. 7, the wall amount is evaluated, and this can be added to the seismic walls 62 and 63.

  That is, in the past, it was not permitted to evaluate the wall magnification and include it in the wall amount because the column is not a seismic wall, but this test allows the wall column to be included in the wall amount. The engineering basis for this has been clarified.

  Therefore, in the future, it will be possible to calculate the wall magnification of the wall column of the rigid frame and add it to other earthquake resistant walls, and it is expected that the degree of freedom of design will be greatly expanded.
