Description

wooden buildings

technical field

The utility model relates to wooden buildings. The utility model particularly relates to the skeleton structure of wooden buildings.

Background technique

As typical construction methods of wooden buildings such as wooden houses, there are known a wooden frame construction method and a frame-assembled wall construction method (2×4 board construction method). The wooden frame construction method is widely known as a traditional construction method (original construction method) in Japan. In this wooden frame construction method, wood constituting frame members such as pillars, floor beams, roof beams, and girders are erected, and reinforcing materials such as diagonal pillars, wall materials, etc. are fixed to the frame members to form a wooden building. In addition, the frame assembly wall construction method is, for example, a construction method based on a frame material having a component cross section of 2 inches by 4 inches. In the frame-assembled wall construction method, a wall body or the like is mainly assembled with surface materials such as laminated boards on a frame material, and fixed with nails for erection, thereby forming a wooden building.

In the existing wooden frame construction methods, since special joints or joint constructions are required for wood joining, advanced craftsmen or skills are required. Therefore, the standardization of construction materials of wooden buildings, the standardization of skills, and the rapidity and ease of construction cannot be met in the existing wooden frame construction methods. In addition, in the wooden frame construction method, the rigidity of the horizontal structural plane carrying the horizontal force is small. Therefore, it is difficult to install a large space such as a wide living space in a building, and it is necessary to arrange a plurality of pillars in accordance with the room layout. Therefore, the conventional wooden frame construction method has a low degree of freedom in room layout and arrangement of openings, and it is difficult to change the room layout according to the life cycle.

On the other hand, in the frame assembling wall construction method, work can be simplified so that construction can be performed without special skills. However, since the horizontal force applied to the skeleton is maintained by the wall plate provided on the frame, it is difficult to provide a large opening in the building, and it is difficult to obtain the required strength because the cross-section of the parts facing the direction of wind pressure is small. Problems. In addition, in the frame assembly wall construction method, since the components are made of manufactured materials, if the material length of the components is long, there is a high possibility of bending and twisting. In addition, even if the components are exposed and used as finishing materials, the texture and design of the manufacturing materials themselves are poor, and there is a problem that it is difficult to express a sense of luxury.

In addition, in recent years, there is a tendency to use a large space without walls and pillars as a living space to improve livability, relaxation, design freedom, and application adaptability. However, when designing a large space using the above-mentioned existing construction methods, as the distance between the fulcrums of the beam increases, the section of the beam needs to be enlarged. However, since the self-weight of the beam increases due to the expansion of the cross-section of the beam parts, the distance between the fulcrums of the beam is limited due to constraints such as deflection and resistance of the beam. Therefore, it is difficult to design a large space in each of the existing construction methods.

In addition, in order to facilitate the observation of the interior of the wooden building 1 in FIG. 1A , the illustration omits one side of the inclined surface sandwiching the ridge wood 194 between the roof trusses.

In the wooden building 1 , joints are formed using appropriate joint metal sheets for various members constituting the frame. Next, the frame structure of the wooden building 1 shown in FIG. 1A will be described as an example of the structural members and joining metal parts of the wooden building 1 of the present invention.

-Column-to-beam junction-

First, the junction of vertical members such as through columns 121 and uprights 123 and horizontal members such as beams 14 and inter-column tie beams 144 of the wooden building 1 and joint metal fittings for joining will be described. In addition, members to be joined via the beam support metal parts and joint metal parts described below are not limited to the illustrated vertical materials and horizontal materials. In addition, the beam 14 includes a floor beam 141 , a tie beam 144 between columns, a joist 143 , and other horizontal members.

(beam support fittings A) (refer to Figure 2)

Fig. 2 is an exploded vertical view showing an example of a column-beam connection.

First, the steel joint metal fittings used in the case of joining the end faces of the beams 14 on the side surfaces of the pillars 12 in the column-to-beam joint (column-through joint) will be described. The column penetration form is formed at the junction of horizontal materials such as floor beams 141 and inter-column tie beams 144 and vertical materials such as through columns 121 or upright columns 123 . The joint portion of such column penetration joint joins together the beam support metal fitting 2A, the offset pin 101 and the bolt 102 .

The beam support metal fitting 2A is formed by bending a metal plate. As shown in FIG. 2 , the beam support metal fitting 2A has a back plate 21 fixed to the side surface of the support column 12 (or through column 121 ), and a plate-shaped support piece 23 extending from the back plate 21 so as to be perpendicular to the support column 12 . ,twenty three.

The back plate 21 is a vertically long rectangular plate-shaped body having a width about one-third of the width of the pillar 12 . Fasteners such as bolts and nuts are used to fix the back plate 21 to the joint position of the beam 14 , that is, one side of the pillar 12 . A plurality of bolt holes (not shown) are formed at predetermined intervals on the back plate 21 . The same number of bolt holes with the same diameter are also formed on the side surfaces of the corresponding pillars 12 .

The supporting pieces 23 , 23 are respectively disposed on both ends of the backplane 21 in the width direction. The upper edge of each support piece 23 has a shape bent downward from the front end of the support piece 23 . Each support piece 23 has a slot 231 in the shape of an elongated hole opening at the upper end edge and extending downward at a position close to its front end. In addition, a plurality of circular pin holes 232 are arranged along the height direction at the front end of the support piece 23 .

The beam 14 has an insertion groove 151 extending in the longitudinal direction from the end, and can be fitted into the support piece 23 of the beam support fitting 2A. The fitting groove 151 corresponds to each support piece 23 of the beam support metal fitting 2A, and is formed in two so as to roughly divide the end portion of the beam 14 (joint portion with the pillar 12 ) into three in the width direction. In addition, the fitting groove 151 is formed in a size corresponding to the width and length of the support piece 23 of the beam support metal fitting 2A.

In addition, the beam 14 has a plurality of pin holes 153 on the side surface. These pin holes 153 are formed at positions corresponding to the respective pin holes 232 of the beam support metal fitting 2A. The pin hole 153 of the beam 14 is formed at the end of the beam 14 roughly divided into three by a length exceeding at least the second insertion groove 151 from one side. In addition, bolts 102 are attached above these pin holes 153 to penetrate the width direction of the beam 14 .

The punching pin 101 is pressed in horizontally from one side of the beam 14 relative to the pin hole 153 of the beam 14 . In addition, the punch pin 101 penetrates the support piece 23 of the beam support metal fitting 2A, and has a length substantially corresponding to the pin hole 153 of the beam 14 . That is, the counter pins 101 are respectively nailed into the pin holes 153 of the beam 14, and the front end abuts against the inner end (bottom of the hole) of the pin holes 153 . . . Access to several interior ways is formed. The punching pin 101 is knurled on the outer peripheral surface on the base end side to have concavo-convex portions.

·Joint structure

Next, a method of joining a column-to-beam joint using the beam support fitting 2A configured as described above and the punch pin 101 will be described.

First, arrange the beam support metal fitting 2A at a predetermined position on the side surface of the pillar 12, insert the shaft portion of the bolt 102 from the bolt hole of the beam supporting metal fitting 2A into the bolt hole of the pillar 12, and screw the nut to the front end through a washer. , the beam support metal fitting 2A is fixed to the side of the beam 14 . At this time, the front ends of the bolts 102 and the nuts are housed in holes (not shown) provided in the pillar 12 and are not exposed to the outside. Therefore, the external design of the periphery of the column-to-beam joint is not spoiled, and the joint with other beam materials and the like is not hindered.

Next, the fitting groove 151 of the beam 14 is joined to the beam support metal fitting 2A. At this time, the bolts 102 previously attached to the beam 14 are slid into the slot holes 231 of the respective support pieces 23 of the beam support metal fitting 2A and engaged. Thereby, the beam 14 can be easily positioned and held at the joining position of the upper end portion of the strut 12 . In addition, the offset pin 101 is driven into the pin hole 153 of the beam 14 . Thereby, the beam 14 can be fixed to the support|pillar 12 easily and quickly. At this time, the punching pin 101 is completely driven into the pin hole 153 of the beam 14 , whereby the base end of the punching pin 101 enters a little bit from the opening end of the pin hole 153 . Thus, the blanking pin 101 is hidden in the pin hole 153 of the beam 14 .

Thereby, the beam 14 and the pillar 12 are firmly integrated using the beam support metal fittings 2A, and the skeleton of the wooden building 1 is comprised. The beam support metal fittings 2A are hidden inside the beam 14 and are not exposed to the outside. Therefore, the column-to-beam joint is better accommodated using the beam support metal fittings 2A, and becomes a high-strength joint. In addition, the pillars 12 of the upper stage and the pillars 12 of the lower stage are joined via a joining metal fitting 3 to be described later.

(beam supporting metal fitting B) (refer to Fig. 3)

Fig. 3 is an exploded perspective view showing another example of a column-to-beam joint. FIG. 3 shows a state in which a column 12 of a flat cross section is joined to a beam 14 in the longitudinal direction of the section (joint portion of a column of a rigid frame and a beam).

The beam supporting metal fitting 2B shown in FIG. 3 is a modification of the above-mentioned beam supporting metal fitting 2A, and is fixed by a tenon member 25, a offset pin 101, a bolt 102, and the like.

The bolt 102 is a general bolt having a head of an appropriate shape such as a hexagon or a square at one end of a shaft portion having a male thread. The basic structure of the beam support metal fitting 2B is the same as that of the beam support metal fitting 2A shown in FIG. A plurality of bolt holes 211 are formed at predetermined intervals on the back plate 21 . The shape of the upper edge of the support piece 23 of the beam support metal fitting 2B is linear, and the slot 231 is opened respectively.

This beam support metal fitting 2B is characterized in that it includes a tenon member 25 for fixing the beam support metal fitting 2B to the pillar 12 . The tenon member 25 includes: a nut portion 251 having a female thread threadedly engaged with the male thread of the bolt 102 ; and a cylindrical portion 252 externally mounted on the nut portion 251 . The nut portion 251 is built into one end of the cylindrical portion 252 so as to protrude only from the cylindrical portion 252 , and is integrated with the cylindrical portion 252 by welding or the like. The cylindrical portion 252 has a pin hole 253 in a direction perpendicular to the axis on a side opposite to the nut portion 251 .

·Joint structure

The joining of the pillar 12 and the beam 14 using this beam support metal fitting 2B is performed in the following order. First, a tenon hole 137 into which the tenon member 25 is inserted and a pin hole 133 for inserting the offset pin 101 and the like are formed on the side surface of the pillar 12 . The tenon member 2560 is inserted into the tenon hole 137 , and then the counter pin 101 and the like are inserted into the pin hole 133 , and the tenon member 25 is first installed in the pillar 12 .

An insertion groove 151 conforming to the shape of the beam support metal fitting 2B and a pin hole 153 for inserting the punch pin 101 and the like are formed at the end of the beam 14 . The beam support metal part 2B abuts against the side of the pillar 12 on which the tenon part 25 is installed first, inserts the bolt 102 into the bolt hole 211 of the back plate 21 from between the two supporting pieces 23, and is threadedly connected with the nut part 251 of the tenon part 25. As a result, the beam support metal fitting 2B is fixed to the pillar 12 .

Next, the supporting piece 23 of the beam supporting metal fitting 2B is inserted into the fitting groove 151 of the beam 14 , and the blanking pin 101 etc. are inserted from the side of the beam 14 to connect the beam supporting metal fitting 2B and the beam 14 .

Such beam supporting metal fittings 2A, 2B (hereinafter collectively referred to as beam supporting metal fittings 2 ) do not require processing such as jointing and joining at the junction of pillars and beams, and labor-saving and high-strength junctions can be formed. That is, these beam supporting metal parts 2 are quite different from the reinforcing metal parts of the conventional wooden framework construction method, and there is no cross-sectional defect of the structural material, and there is no need to install other metal parts such as the Hana board metal parts. In addition, the beam support metal fittings 2 are first installed on the structural members, and only the insertion of the horizontal material into the beam support metal fittings 2 and the nailing of the offset pins 101 can be performed on site. Therefore, the construction is extremely simple, and tools can be reduced. Homework is simplified. In addition, the beam support metal fittings 2 can be suitably used not only for such a column-beam joint as described above, but also for joints of various vertical members and horizontal members.

(Joint metal parts A) (refer to Fig. 4 and Fig. 5)

Next, the joining metal parts used in the case of joining the end surface of the support column 12 to the upper surface or the lower surface of the beam 14 with priority to the continuity of the support column 12 and the beam 14 in the column-beam joint (beam through-type joint) Be explained. The joints of the beam penetration form are formed at the joints of the horizontal materials of the inter-column bollards 144 and the floor beams 141, the joints of the vertical materials such as the columns 123 and the inter-columns 126, and are set in the wooden buildings 1 having more than two floors.

Fig. 4 is a front view showing an example of a joint metal fitting used in a beam-through joint portion.

The joint metal fitting 3A is a steel metal fitting having a pipe portion 31 and a plate portion 33 .

The plate portion 33 includes a plate-shaped fitting piece 331 having a width corresponding to the inner diameter of the pipe portion 31 on one side. The fitting piece 331 is fitted to one end of the pipe portion 31 . The plate portion 33 and the pipe portion 31 are integrated by flash welding the fitting piece 331 to the pipe portion 31 . The pipe portion 31 extends on one side of the plate portion 33 on the same axis as the plate portion 33 .

Through-holes 311 and 323 for punching or bolts are respectively formed in the pipe portion 31 and the plate portion 33 . The through-hole 311 provided in the pipe part 31 and the through-hole 332 provided in the plate part 33 are formed to pass through in the same direction.

In this joint metal fitting 3A, the size of the plate portion 33 is basically a square with a size corresponding to the width of the pillar 12 to be joined, and the width thereof increases and decreases according to the number of through holes provided in the plate portion 33 . In addition, the length of the pipe portion 31 and the number of through-holes provided in the plate portion 33 and the pipe portion 33 are preferably appropriately set according to the required pull-out resistance.

·Joint structure

Fig. 5 is a side view partially cut away showing a joint portion of a column beam using the joint metal fitting shown in Fig. 4 .

At this time, the pipe portion 31 and the tenon hole 155 can be inserted smoothly without interfering with each other, and the strength required for the joint metal fitting 1 can be ensured, so that a structure satisfying the strength performance of the joint can be realized.

In addition, by using such a joint metal fitting 3A for the joint portion of the pillar beam, the depth of the notch 135 formed in the end surface of the pillar 12 can be set to be equal to or greater than the width of the pillar. As a result, the notch 135 can be processed with a small-diameter circular saw, and the processing can be performed extremely easily. In addition, even if the notch 135 has such a depth, sufficient joint strength and adhesiveness can be ensured practically by appropriately designing the size of the joint metal fitting 3A and the arrangement of bolts and pins.

The tube portion 31 is provided with three through holes 311 in the cylindrical portion, and one through hole 311 is provided in the overlapping portion 312 .

The pipe portion 31 has a notch (not shown) corresponding to the thickness of the plate portion 33 at the front end. The joining metal fitting 3B sandwiches the plate portion 33 at the cutout of the pipe portion 31 , and the plate portion 33 and the pipe portion 31 are integrated into a featherboard shape by welding or the like. Such an integrated joining metal fitting 3B resists with a high pull-out resistance depending on the length of the pipe portion 31 and the number of penetrating pins. In the case of the metal joint 3B shown in FIG. 7 , a pull-out force of about 50 kN can be calculated.

・Joint structure (see Fig. 8A, Fig. 8B)

Next, the junction structure of the pillar 12 and the beam 14 using the junction metal fitting 3B will be described with reference to FIGS. 8A and 8B . As described above, there are various changes in the size of the pipe portion 31 and the plate portion 33 , the arrangement and the number of the through holes 311 and 332 in the metal joint 3B. By appropriately selecting and arranging them, the metal joint 3B exhibits sufficient joint strength and adhesiveness practically.

8A and 8B show the joint structure of the pillar 12 and the beam 14 using the joint metal fitting 3B. FIG. 8A is a side view showing the joint part partially cut away, and FIG. 8B is a cross-sectional view.

In FIG. 8A , the upper pillar 12 and the lower pillar 12 on which the clamping beam 14 is vertically erected are joined via paired two joining metal parts 3B, 3B. Two through holes 332 are provided in the plate portion 33 of the upper joining metal fitting 3B, and three through holes 332 are provided in the plate portion 33 of the lower joining metal fitting 3B.

On each of the upper and lower pillars 12 , a notch 135 is formed in the end surface (wood cross section) along the width direction of the pillar 12 and fitted into the plate portion 33 of the joint metal fitting 3B. Each of these notches 135 can be processed with a small-diameter circular saw with a diameter of about 30 cm, so they can be easily formed.

The beam 14 is provided with a tenon hole 155 penetrating through the thickness direction of the beam and fitting into the pipe portion 31 of the joint metal fitting 3B. Mortise holes 155 are provided in contact portions of the beam 14 with the respective end surfaces of the upper and lower pillars 12 .

The pipe portion 31 of the joint metal fitting 3B is fitted into the tenon hole 155 from the top surface side of the beam 14 . In addition, the plate portion 33 fits into the notch 135 of the upper column 12 , and the pipe portion 31 fits into the tenon hole 155 from the lower surface side of the beam 14 . In addition, the plate portion 33 fits into the cutout 135 of the lower pillar 12 .

Here, on the top surface side of the beam 14, the pipe portion 31 of the joint metal fitting 3B joined to the upper pillar 12 and the pipe portion 31 of the joint metal fitting 3B joined to the lower pillar 12 pass through the ends of the respective pipe portions 31. The overlapping portions 312 overlap each other and are coaxially arranged.

As shown in FIG. 8B , insert pins (or bolts) 101 into the through-holes through pin holes 133 and 153 from the side surfaces of the upper and lower pillars 12 and beams 14 in the joining metal fittings 3B and 3B that are continuously embedded in the pillars 12 and beams 14. Inside 311 and 332. As a result, the joint metal fitting 3B is fixed to the pillar 12 and the beam 14, and the pillar 12 and the beam 14 are integrally joined. Simultaneously, one punch 101 is also inserted into the through hole 311 passing through the overlapping portion 312 of each pipe portion 31, and the two joining metal parts 3B are connected to each other.

In the column-beam joint, shear resistance such as the inserted pin 101 ensures the joint strength of the joint metal fitting 3B, and can tightly connect the ends of the pillar 12 and the beam 14 . In addition, the overlapping parts 312 of the two joining metal parts 3B can be overlapped in one mortise 155 , and can be combined by using a single punch 101 , so that the two pipe parts 31 , 31 can be arranged coaxially. In the example shown in FIG. 8B , one of the three punching pins 101 inserted in the pipe portion 31 of each joint metal fitting 3B in common and passing through the overlapping portion 312 , and the upper two pins are used to join the upper pillar 12 . As for the metal parts 3B, the lower two are used to join the joint metal parts 3B of the lower pillars 12 . Accordingly, the joint strength required for the column-to-beam joint can be ensured. As a result, component costs and processing costs can be reduced. In addition, even when a large pull-out resistance is required in the column-beam joint, it is not necessary to increase the thickness of the beam, and a reasonable joint that is sufficiently resistant to the pull-out force acting on the column can be produced.

In such a column-to-beam joint, the joint metal 3B is appropriately selected in consideration of the pull-out resistance required for the pillar 12 and the vertical load from the upper layer, and may be used in combination of different types. That is, the joint metal fitting 3B is not limited to the above configuration, and may have a configuration corresponding to the number of through holes 311 and 332 of the pipe portion 31 and the plate portion 33 and the pipe length to the required pull-out resistance.

(Joint metal fitting C) (refer to FIG. 9 )

Fig. 9 shows still another example of the joining metal fittings, and is a side view showing a joint part of a pillar and a beam partially cut away.

The joint metal fitting 3C provided at the joint portion is provided with a support plate 35 between the pipe portion 31 and the plate portion 33 . The support plate 35 prevents the plate portion 33 from being pressed into the joint surface of the strut 12 and the beam 14 .

For example, in the form shown in FIG. 9 , the joint metal fitting 3C is provided with a support plate 35 at a joint portion between the pipe portion 31 and the plate portion 33 so as to be perpendicular to both the pipe portion 31 and the plate portion 33 . The support plate 35 is formed in a rectangle. The shape of the support plate 35 is not limited to a rectangle, and it is formed to the same extent as the wooden section of the column 123 joined by the joint metal fitting 3C, or slightly larger than it, and does not exceed the width of the floor beam 141 at most.

By providing such a support plate 35 on the joint metal fitting 3C, the plate portion 33 of the joint metal fitting 3C distributes the load and prevents the pillar 123 or the floor beam 141 from being pressed into the column-beam joint where a heavy load acts.

In FIG. 9, a floor beam 141 has a floor 142 laid thereon. The load acting on the floor beam 141 is borne by the support plate 35 and is equally transmitted to the column 123 . The ends of the floor beams 141 are joined to the pillars 12 . The upper pillar 12 of the pillar 12 is joined by the tenon tube 27 and the offset pin 101 . In addition, the pillar 12 engages the end of the floor beam 141 via the beam supporting metal 2 . The lower part of the tenon tube 27 is integrated with the pillar 12 in such a way that the bolt 102 of the fixing beam supporting metal part 2 penetrates, and the pulling resistance is maintained.

(joint metal fitting D) (refer to FIG. 10A, FIG. 10B )

The joint metal fitting used for the column-beam joint part may be the joint metal fitting which couples the several pipe part 31 to the plate part 33 other than the above.

FIG. 10A is a partially cutaway side view showing a column-to-beam joint using the joint metal fitting 3D, and FIG. 10B is a partially cutaway plan view showing the joint.

As shown in FIG. 10A , the joint metal fitting 3D has a shape including two pipe portions 31 with respect to the plate portion 33 . Each tube portion 31 extends in parallel from one side of the plate portion 33 . A plurality of through holes 332 are provided in the plate portion 33 . In addition, as shown in FIG. 10A, the plurality of through-holes 311 provided in each pipe portion 31 are not formed at a common height position, and the through-holes 311 of one pipe portion 31 and the through-holes 311 of the other pipe portion 31 are mutually staggered in height positions. to set.

·Joint structure

Next, the junction structure of the pillar 12x and the beam 14x using the junction metal 3D will be described with reference to FIGS. 10A and 10B . As mentioned above, the head part of the lower stage pillar 12x and the beam 14x are joined via the two joining metal fittings 3D arrange|positioned parallel to the material axis direction of the beam 14x.

That is, the lower pillar 12x is a mid-section laminated material with a long rectangular cross-sectional shape, and its longitudinal direction is arranged parallel to the material axis of the beam. For this pillar 12, the beam 14x is joined to the beam 14x using the joint metal fitting 3D in pairs.

The tenon holes 155 formed in the beams 14x correspond to the number and intervals of the pipe portions 31 of the joint metal 3D, and are provided at predetermined intervals in the inter-beam direction. The pipe parts 31 and 31 of the joining metal fitting 3D are fitted into the respective mortise holes 155 from below, and are joined to the beam 14 by a pin (or bolt) 101 driven in from the side of the beam 14x.

The plate part 33 of the joining metal fitting 3D is inserted into the notch 135 formed in the head part of the support 12, and is joined with the support 12x by the pin (or bolt) 101 driven in from the side of the support 12x. The joining metal parts 3D are equally arranged at two positions along the long axis direction of the cross section of the strut 12x, so that the head of the strut 12x and the beam 14x are rigidly joined with sufficient strength. form a rigid structure.

-Joint portion between beams- (refer to FIG. 10A, FIG. 10B )

Next, joints between horizontal members such as beams and inter-column tie beams will be described.

As described above, in the column-beam joint shown in FIG. 10A , the head of the lower column 12x and the beam 14x are rigidly joined with a sufficient strength by the joint metal parts 3D, 3D in pairs. Moreover, as shown in FIG. 10B, the beam 14y and this beam 14x are joined by the end part in L shape.

That is, the beam support metal fitting 2 which joins beams is provided in the intersection part of the beam 14x of X direction, and the beam 14y of Y direction, and joins these beams 14x, 14y. As shown in FIG. 10A , the heads of the lower-stage pillars 12y and the beams 14y are joined via the same joining metal 3D. A female screw is formed at the upper end of the pipe portion 31 of the joining metal fitting 3D joining the beam 14y and the lower stage pillar 12y. And, the leg joint fittings 4 for connecting the upper stage pillar 12y are fastened to the female screw of the pipe portion 31 via the short bolts 103 .

Also, as shown in FIG. 2 , the beam support metal fitting 2 has a back plate 21 and two parallel support pieces 23 protruding laterally perpendicular to the back plate 21 . Bolt holes are formed in the back plate 21 in alignment with the pipe portion 31 of the joint metal fitting 3D at a pitch. As for the beam supporting metal 2 abutting against the side of the beam 14y, the back plate 21 is coupled together by bolts 102 for fixing the pipe portion 31, fixed to the beam 14y. The support piece 23 of the beam support metal fitting 2 is inserted into the fitting groove formed in the end of the other beam 14x, and the beam 14x is coupled with the beam 14x by a punch (or bolt) 101 driven from the side of the beam 14x.

In addition, the upper column 12y is joined to the beam 14y in the Y direction via the column leg joint metal fitting 4 . The column leg joint metal parts 4 are erected vertically to form two parallel mounting plates 47, and these mounting plates 47, 47 are inserted into two cutouts formed in the legs of the upper column 12y, and are formed by offset pins nailed from the side of the column 12y. 101 is combined with the support 12y.

Thereby, the beam 14x in the X direction and the beam 14y in the Y direction are firmly integrated using the beam support metal fittings 2, and constitute the skeleton of the wooden building 1. The beam support metal fittings 2 are concealed inside the beams 14x, 14y and are not exposed to the outside, so they can be properly accommodated and form a high-strength joint.

-main body-

(Laminated timber rigid frame) (refer to Figure 11-13)

Next, the structural main body of the wooden building 1 whose basic form is a rigid structure will be described with reference to FIGS. 11 to 13 .

FIG. 11 is a front view of a rigid frame according to the embodiment, and FIG. 12 is a front view showing a column-beam junction of the rigid frame.

The rigid structure of the wooden building 1 can be advantageously used instead of the existing wooden frame construction method and wooden frame construction method, and is suitable for relatively small-scale wooden buildings mainly including residences.

In addition, by appropriately selecting or combining the various types of beam support metal fittings and joint metal fittings described above to form the joints of the wooden building 1 , it is possible to adopt a wooden structure body whose basic form is a rigid structure. That is, in the wooden building 1, the skeleton can be composed mainly of the wooden rigid frame. As main structural materials such as pillars 12 and beams 14 , single materials of middle-section or small-section laminated materials can be used.

Such wooden rigid frames can be properly combined according to the shape of the building. In addition, the shape of the rigid frame can be a variety of forms such as door shape, mountain shape, trapezoid shape, etc., and can be used as a single layer or multiple layers.

In addition, the laminated lumber includes a structural laminated lumber and an interior laminated lumber, and is mainly used as a structural laminated lumber in the present invention. In the following description, the so-called "large cross-section laminated lumber" means that the short side of the cross-section is 15 cm or more, and the cross-sectional area is 300 cm2 or more, and the "medium cross-section laminated lumber" means that the short side of the cross-section is 7.5 cm or more, and the long side is 15 cm or more , for laminated lumber other than large-section laminated lumber, "small-section laminated lumber" refers to laminated lumber with a cross-section of less than 7.5 cm on the short side or less than 15 cm on the long side.

The pillars 12 and the beams 14 shown in FIGS. 11 and 12 are made of middle-section laminated materials. The pillar 12 and the beam 14 are rigidly joined at each junction using a pair of joining metal fittings 3E. The joint metal fitting 3E is basically the same in configuration as the joint metal fitting 3A shown in FIG. 4 . Therefore, the common configurations of the metal joint 3E and the metal joint 3A are denoted by the same symbols as those described above, and detailed description thereof will be omitted.

In the upper end of the support 12, a cutout 135 is formed in the cross-section of the wood along the width direction of the support (the left-right direction in FIG. illustration omitted).

Two tenon holes 155 penetrating through the thickness direction of the beams are formed at intervals along the direction between the beams 14 at the contact portion of the beams 14 with the pillars 12 . With the joining metal fitting 3E, the pipe portion 31 is fitted into each tenon hole 155 of the beam 14 , and on the other hand, the plate portion 33 is fitted into the notch 135 of the pillar 12 . The joining metal fittings 3E are uniformly arranged in the joining portion of the pillar 12 and the beam 14 along the material axis direction of the beam 14 in terms of structural resistance. More preferably, the two joining metal fittings 3E, 3E are respectively arranged in the vicinity of both ends of the contact portion with the beam 14 at the head portion of the pillar 12 .

Each joint metal fitting 3E is inserted across the pillar 12 and the beam 14 . Each joint metal fitting 3E is integrally joined to the pillar 12 and the beam 14 via a plurality of punch pins 101 and bolts 102 inserted from the side of the pillar 12 and the beam 14 (front or rear in FIG. 12 ). The punch 101 secures the strength of the joint by its shear resistance. When the bolts 102 are used, the bolts 102 are connected to the nuts, thereby also functioning to fasten and connect the end portions of the column beams having the notches 135 , the mortise holes 155 , and the like.

In this way, the pillar 12 and the beam 14 are joined via the pair of joining metal fittings 3E, 3E arranged at a distance from each other. Thereby, the resistance force in the rotation direction of the junction part of the support|pillar 12 and the beam 14 is strengthened. In addition, it is possible to form a strong rigid frame in which the junction between the pillar 12 and the beam 14 is rigidly joined. In addition, the structural surface composed of the pillar 12 and the beam 14 can be used as a unidirectional rigid structural surface having horizontal resistance only in the material axis direction of the beam.

In addition, the auxiliary metal fitting 37 may also be arranged between the pair of joining metal fittings 3E, 3E arranged as described above. The auxiliary metal fitting 37 is formed, for example, in a cylindrical shape having substantially the same diameter as the pipe portion 31 of the joining metal fitting 3E, or in a flat plate shape having substantially the same thickness as the plate portion 33 of the joining fitting 3E. Through-holes 371 for punching pins or bolts are provided at both ends of the auxiliary metal fitting 37 .

Both ends of the auxiliary metal fitting 37 are inserted into the notch 135 formed in the pillar 12 and the notch or hole (not shown) formed in the beam 14 , and are fixed by pins (or bolts) 101 like the joint metal fitting 3E.

In this way, by using the joint metal fitting 3E and the auxiliary metal fitting 37 in combination, the pillar 12 and the beam 14 are joined together, thereby strengthening the resistance force in the shear direction of the joint portion of the pillar 12 and the beam 14 . The slit 135 provided in the pillar 12 for fitting the plate portion 33 of the joint metal fitting 3E can be processed by a small-diameter circular saw with a diameter of about 30 cm, so it can be formed with an easy operation. The legs of the pillar 12 and the foundation 16 are joined using leg metal fittings described later.

Fig. 13 shows another form of the rigid frame, and is a front view of the column-beam junction.

As shown in FIG. 13 , a joint metal fitting 3F having two pipe portions 31 and a plate portion 33 may also be used to constitute the column-to-beam joint. The joint metal fitting 3F is basically the same in configuration as the joint metal fitting 3D shown in FIG. 10A . Therefore, the common configuration of the metal joint 3F and the metal joint 3D uses the same symbols as those described above, and the detailed description thereof will be omitted.

In this joint metal fitting 3F, an elongated hole 314 is provided at a joint portion (lower end side of the pipe parts 31 , 31 ) with the two pipe parts 31 and the plate part 33 . The elongated hole 314 is formed by notching the lower end of the pipe portion 31 elongatedly. The long holes 314 are formed on both the front side and the back side of the pipe portion 31 .

These elongated holes 314 add ductility (toughness) to the joint portion of the plate portion 33 and the pipe portion 31, and function to reduce the yield strength of the joint portion. Therefore, when an impact load acts on the joint between the pillar 12 and the beam 14, it is easy to prevent fractures around the pin 101 penetrating through the pillar 12 or beam 14 made of wood or around the mortise hole 155 of the beam 14, etc.

(Laminated timber rigid structure) (refer to Fig. 10A, Fig. 10B, Fig. 14)

FIG. 14 is a perspective view schematically showing an example of a structure main body in a case where a laminated timber rigid structure is adopted in a wooden building 1 by applying the above-mentioned rigid frame.

The main body is a three-story building, and a unidirectional rigid structural surface is constructed on each floor in the form of beams passing through the columns 12 (2x, 2y) and beams 14 (3x, 3y) in each direction of the X direction and the Y direction. The material length of the pillar 12 is divided in each layer, the legs of the pillar 12 of the first floor are joined to the foundation 16 made of reinforced concrete, and the head of the pillar 12 of the first floor and the legs and the head of the pillar 12 of the upper floor are connected to each other. The layers are joined by beams 14 continuous in the horizontal direction.

The pillars 12 and the beams 14 each use a long rectangular cross-section mid-section laminated material. The standard cross-sectional size of the pillar 12 is 120-150 mm on the short side x 330-370 mm on the long side, and the standard cross-sectional size of the beam 14 is 120-150 mm wide x 330-450 mm high. The strut 12 is joined to the beam 14 so that its longitudinal direction (strength axis direction) is parallel to the material axis direction of the beam 14 .

In the exemplary form, the position of the pillar 12x is displaced in the material axis direction (X direction) of the beam 14x in the first-floor portion and the second and third-floor portions of the structural surface in the X direction, and in the structural surface in the Y direction In the 1st, 2nd, and 3rd floor sections, the position of the pillar 12y is displaced in the material axis direction (Y direction) of the beam 14y. In this way, it is characteristic of the wooden building 1 of the present invention that the positions of the pillars 12 can be freely displaced for each floor. In addition, this is made possible by the junction structure of the pillar 12 and the beam 14 using the above-mentioned beam support fittings 2 and the junction fittings 3D and the like.

For example, the corner J where the rigid structural surface in the X direction and the rigid structural surface in the Y direction are orthogonally joined has the junction structure shown in FIGS. 10A and 10B . In this corner J, the beam 14x in the X direction and the beam 14y in the Y direction are pin-joined by the beam support metal fittings 2 ( 2A, 2B) shown in FIGS. 2 and 3 . However, the corner posts 12x constituting the rigid structural surface in the X direction and the corner posts 12y constituting the rigid structural surface in the Y direction are not directly joined, and each corner post 12x, 12y is rigidly joined to the beams 14x, 14y in each direction by the joint metal fitting 3D.

According to the joining structure of the corner portion J, the pillar 12x constituting the structural surface in the X direction and the pillar 12y constituting the structural surface in the Y direction are erected close to each other in the vicinity of the corner end. However, the positions of the pillars 12x and 12y in each direction can be independently determined regardless of the positions of the pillars 12y and 12x in other directions.

In the form shown in FIG. 14 , the pillars 12y constituting the structural surface in the Y direction are arranged so as to coincide with the corner ends where the beams 14 intersect each other, and the corner pillars 12x constituting the structural surface in the X direction are arranged slightly away from the corner ends. . In addition, as shown in the drawing, the positions of the pillars 12x may be shifted between the first floor and the second and third floors. In addition, not only the pillar 12x in the X direction but also the pillar 12y in the Y direction can be moved to a position away from the corner end.

As described above, as long as the positions of the pillars 12x constituting the rigid structural surface in the X direction and the positions of the pillars 12y constituting the rigid structural surface in the Y direction can be independently determined, for example, it is easy to provide an opening without a pillar straddling a corner end. In addition, the arrangement of the pillars near the corners can be changed for each floor, so the degree of freedom in design is further expanded.

In addition, this laminated material rigid structure is characterized by the use of a pair of struts 12 made of mid-section laminated lumber adjacent to each other in at least one layer, and the head and legs joined to the struts 12 in a beam-through manner. The beams 14 made of mid-section laminated lumber form a unidirectional rigid structural surface on each floor. Therefore, for example, it is also possible to use a part of the layers as a rigid structural surface composed of the mid-section laminated lumber pillars 12 and beams 14, and combine structural surfaces formed by other construction methods in other layers. In addition, in a specific layer, the rigid structural surface formed by the pillars 12 and beams 14 of the mid-section laminated lumber and the structural surface formed by other construction methods may also be connected in the horizontal direction.

In addition, one of the pair of pillars 12 ( 12 x , 12 y ) composed of mid-section laminated materials joined by beam penetration can be replaced with a small cross-section resistance column 127 .

The short side of the resistance column 127 is 120-150mm the same as the pillar 12, and the long side is 250mm. That is, it is also possible to use the above-mentioned long rectangular cross-section mid-section laminated material (120 to 150 mm on the short side and 330 to 370 mm on the long side) for one pillar 12 constituting the rigid structural surface, and use a narrower pillar width for the other pillar 12. laminated lumber. In this way, the degree of freedom in design can be further expanded without changing the resistance force of the rigid structural surface. In addition, it is also possible to use one support 12 as a support made of the above-mentioned medium-section laminated material, and use the other support 12 as a combination of a small-section resistance column 127 and a laminate resistance wall.

In this way, a rectangular rigid structural surface in which the heads and legs of a pair of adjacent pillars 12 and 12 are rigidly joined to the beam 14 (the foundation beam 4 can also be regarded as a beam) is constructed. The rigid structural surface is a unidirectional rigid member with horizontal resistance only in the direction of the material axis of the beam 14 .

-column leg-

Next, the leg fittings used for the leg portion of the wooden building 1 will be described with reference to the drawings. 15 and 16 are exploded perspective views showing joints between the pillar and the foundation using the leg fittings, respectively.

(column leg metal parts A) (refer to Figure 15)

The column leg fitting 4A is made of steel, and joins the column (column) 12 and the foundation 16 or the column 12 and the beam 14 of the lower stage. The leg metal fittings 4A shown in FIGS. 15 and 16 include a bottom plate 41 , a spacer 43 , a fixing plate 45 , and a mounting plate 47 . The bottom plate 41 is a plate-like body having a square shape in plan view. The fixing plate 45 is disposed above the bottom plate 41 via the gasket 43 .

The base plate 41 and the fixing plate 45 are each formed of a rectangular flat body and have a size corresponding to the cross section of the pillar. The spacer 43 extends in the axial direction of the support column 12 and forms a substantially cross shape in plan view. The bottom plate 41, the spacer 43, and the fixing plate 45 are integrated by welding or the like.

A mounting plate 47 is erected on the upper surface of the fixing plate 45 . The wooden section of the lower end of the pillar 12 is received on the top of the fixing plate 45 . The mounting plate 47 is joined to the fixing plate 45 by welding or the like. The mounting plate 47 is formed in a substantially rectangular shape, and the corners on both sides of the upper end are rounded. A plurality of pin holes 471 are arranged side by side on the mounting plate 47 .

The bottom plate 41 is divided into four parts by spacers 43 . The bottom plate 41 is provided with insertion holes 411 in each of the four sections.

·Joint structure

Next, the procedure of fixing the leg fittings 4A to the foundation 16 and the procedure of fixing the pillar 12 to the leg fittings 4A will be described.

The pillar 12 is made of angle material. A cutout 135 for fitting the mounting plate 47 is provided at the lower end of the pillar 12 . In addition, a plurality of pin holes 133 are formed through the support 12 at the lower end of the support 12 in a direction substantially perpendicular to the notch 135 .

Preferably, a sheet body impregnated with a water-repellent agent is attached to the wood section of the pillar 12 . The sheet body impregnated with a water-repellent agent is, for example, a foamed sheet made of urethane or the like impregnated with a water-repellent agent. Various materials such as paraffin-based, silicon-based, and alcosilane-based components can be used as components of the water-repellent agent. At this time, various selections can be made in consideration of appropriate chemical components (pyrethrin-based, etc.), stability during storage, and the like.

Anchor bolts 104 are driven into the foundation 16 . The upper ends of the anchor bolts 104 protruding from the upper surface of the foundation 16 are inserted into the bolt insertion holes 411 of the bottom plate 41 and screwed into the nuts 105 . As a result, the leg fittings 4A are fixed to the upper surface of the foundation 16 .

In this case, all the bolt insertion holes 411 may not be used. For example, the anchor bolts 104 may be inserted and fixed to two bolt insertion holes 411 located at diagonal positions among the four bolt insertion holes 411 . In addition, an operation hole 451 is provided in the fixing plate 45 . The work of fastening the nut 105 to the upper end portion of the anchor bolt 104 can be easily performed through the working hole 451 .

Next, the pillar 12 is erected on the leg metal part 4A. The mounting plate 47 of the leg fitting 4A is fitted into the notch 135 of the pillar 12 . Thereafter, the blanking pins 101 are respectively inserted into the respective pin holes 133 of the pillar. At this time, the pin hole 133 of the support 12 and the pin hole 471 of the mounting plate 47 have almost the same diameter and axis, and the offset pin 101 is inserted through both pin holes 133 and 471 at the same time. Thereby, the pillar 12 is joined to the leg fitting 4A.

In addition, a water-repellent-impregnated sheet is interposed between the wooden section of the support 12 and the leg metal 4A. Through the self-weight of the pillar 12, the water-repellent agent moves from the water-repellent agent-impregnated sheet to the wood section. As a result, even if dew or the like intrudes into the side of the pillar 12, it can be resisted by the water-repellent agent, so that the pillar 12 is hard to rot. In addition, it is also possible to directly apply the water-repellent agent to the wood section without impregnating the sheet with the water-repellent agent.

(column leg metal part B) (refer to Figure 16)

A leg fitting 4B as shown in FIG. 16 can be used for the leg portion. The leg fitting 4B shown in FIG. 16 includes a bottom plate 41 directly fixed to the top end of the foundation 16, two mounting plates 47 standing upright from the bottom plate 41, and a pair of overlapping plates 49 stacked on the bottom plate 41 with the mounting plate 47 interposed therebetween. .

The bottom plate 41 is a square plate-shaped body in plan view. Bolt insertion holes are provided at diagonal corners of the bottom plate 41 .

The mounting plate 47 is a rectangular plate-like body in plan view, and is upright welded to the bottom plate 41 . A plurality of pin holes 471 are formed in each mounting plate 47 . The two mounting plates 47 are installed on the bottom plate 41 parallel to each other. The number of mounting plates 47 is not limited to two, and may be three, for example.

The overlapping plate 49 has the same long side as one side of the bottom plate 41, and is a pair of rectangular plate-shaped bodies in plan view. The overlapping plate 49 is welded to the bottom plate 41 with the mounting plates 47 and 47 interposed therebetween. Each overlapping plate 49 has a thickness slightly larger than that of the head of the anchor bolt 104 and forms a recess 491 for receiving the head of the anchor bolt 104 . The concave portion 4 a is provided so as to overlap the bolt insertion hole 2 a of the bottom plate 41 .

·Joint structure

The procedure of fixing such leg fittings 4B to the foundation 16 and the procedure of fixing the pillar 12 to the leg fittings 4B will be described.

Two axial cutouts 135 corresponding to the mounting plate 47 are formed in advance at the lower end of the pillar 12 . In addition, a plurality of pin holes 133 perpendicular to the cut 135 and penetrating the support 12 are formed in advance at the lower end of the support 12 .

In the example shown in FIG. 16 , anchor nuts (not shown) are embedded in the foundation 16 . As the anchor nut, an anchor nut provided with a high nut on a general anchor bolt is used.

After the leg metal parts 4B are placed on the top of the foundation 16, the anchor bolts 104 are inserted through the bolt insertion holes 411 of the bottom plate 41 from above, and are screwed and connected with the anchor nuts. As a result, the leg fittings 4B are fixed to the foundation 16 .

Next, the column 12 is raised, and the mounting plates 47, 47 of the column leg metal fitting 4B are fitted into the cutouts 135, 135 formed at the lower ends thereof. In addition, the pillar 12 is placed on the upper surface of the overlapping plate 49 .

Since the pin insertion holes 471 of the mounting plate 47 and the pin holes 133 of the support 12 respectively match, the offset pins 101 are driven in from one side of the support 12 . Thereby, the support|pillar 12 and the mounting plate 47 of the leg metal fittings 4B can be integrally joined.

Thus, by using the leg fittings 4B shown in FIG. 16 , it is possible to connect the pillar 12 to the foundation 16 without protruding the anchor bolt 104 from the tip of the foundation 16 . In this example, the washer portion for avoiding the excess length of the anchor bolt 104 is unnecessary, and the support column 12 can be fixed without separating the bottom plate 41 and the mounting plate 47 . Therefore, it is possible to lower the fixing position of the lower end portion of the strut 12 . Such leg fittings 4B are suitable for the case where it is desired to lower the level of the floor surface in the wooden building 1 .

These leg fittings 4A, 4B (hereinafter collectively referred to as the leg fittings 4 ) can maintain sufficient pull-out resistance in the wooden building 1 and form a joined structure having a high-strength leg portion.

- Roof truss - (refer to Fig. 1A, Fig. 1B, Fig. 17)

Fig. 17 is an example of a joint portion of a roof truss of a wooden building, and is a side view showing a partially broken joint portion.

When constructing the roof of the wooden building 1, after erecting the upper pillars 12 required for the structure, the roof beams 18 are erected, and the roof truss and the roof are constructed.

As shown in FIG. 1A , the roof truss of the wooden building 1 is provided with a plurality of roof truss pillars 182 on roof beams 18 appropriately combined according to the shape of the roof. A plurality of purlins 19 are arranged on these roof truss pillars 182 . Rafters 192 are provided on the upper surfaces of the purlins 19 . Eaves stringers 185 are provided on the outer sides of the roof beams 18 . Roof joists (not shown) are fitted between the roof beams 18, and roof slabs and tiles are arranged sequentially on the rafters 192. Before the eaves, there are purlins 186 in front of the eaves.

As shown in FIG. 17 , the roof truss pillar 182 is fixed on the top of the roof beam 18 via the tenon tube 51 and the offset pin 101 . The tenon tube 51 is made of a cylindrical metal tube. On the tenon tube 51 , pin holes through which the offset pin 101 or the bolt 102 are inserted are provided at the upper end and the lower end. In addition, the upright column 123 is joined to the roof truss pillar 182 through the tenon tube 51 , and the upper end surface is fixed with the tenon tube 51 and the offset pin 101 with respect to the purlin 19 directly above. The upright column 123 and the roof beam 18 are connected in a through-column form using the beam support metal fittings 2, bolts 102, and the like.

The purlin 19 is joined to the upper end surface of the roof truss column 182 by the tenon tube 51 and the dowel 101 at the position where it straddles the upper end surface of the roof truss column 182 . On the other hand, the purlin 19 is joined to the roof truss pillar 182 via the tenon tube 51 , the purlin support metal fitting 53 , the pin 101 and the bolt 102 at specific positions such as the outer corner (or the inner corner) and the joint.

In the joint portion of the purlins 19 , the purlins 19 are arranged on a straight line with each other, and the roof truss pillar 182 is joined to one purlin 19 .

The purlin support fittings 53 are provided at corners formed by the side surfaces of the roof truss pillars 182 and the lower surfaces of the purlins 19 . The purlin support metal fitting 53 has a contact plate 531 made of a metal plate with an inverted L-shaped cross-section, a tenon portion 532 erected in the center of the top surface of the contact plate 531 , and two sides along the contact plate 531. Two corner plates 533 are disposed in a substantially triangular shape. The tenon portion 532 is formed of a cylindrical metal pipe, and a pin hole is pierced therein. In addition, the contact plate 531 is formed with two bolt insertion holes on the joint surface with the truss pillar 182 .

·Joint structure

Next, the joining procedure of the roof truss pillar 182 and the purlin 19 is demonstrated.

Each purlin 19 is provided with a mortise hole 191 having a predetermined depth in the vertical direction on the lower surface of the end portion. Moreover, the pin hole which penetrates this tenon hole 191 is provided in the end part side surface of the purlin 19, and is not shown in figure.

A tenon hole 183 corresponding to the tenon hole 191 of a purlin 19 is formed on the upper end surface of the roof truss pillar 182 joined with the purlin 19 in the axial direction. In addition, two bolt insertion holes 184 are provided on the side surfaces of the roof truss pillar 182 . Bolt insertion holes 184 on the upper side are formed penetrating through the tenon holes 183 .

The holes provided in these purlins 19 and roof truss pillars 182 are all extremely simple shapes that can be drilled. Therefore, the processing operation for the junction part of the purlin 19 and the roof truss pillar 182 can be performed extremely easily.

When joining, at first, the lower half of the tenon tube 51 is inserted in the tenon hole 183 of the roof truss pillar 182, so that the pin hole of the tenon tube 51 coincides with the bolt insertion hole 184 of the roof truss pillar 182. Then, the purlin support metal fittings 53 are brought into contact with the side surfaces of the truss pillars 182 , and the two bolt insertion holes of the abutment plate 531 are respectively matched with the bolt insertion holes 184 of the roof truss pillars 182 . In this state, the two bolts 102 are inserted so as to pass through these bolt insertion holes 184, and are fastened and connected with nuts. Thereby, the purlin support metal fitting 53 and the roof truss support 182 can be connected.

At this time, the upper bolts 102 pass through the bolt insertion holes 184 on the upper side of the tenon tube 51 to fasten the tenon tube 51 together. Thus, the tenon tube 51 is fixed to the roof truss pillar 182 . In addition, the previous work can be performed at the factory in advance, and it is possible to improve the work efficiency on site.

Next, the tenon hole 191 of a purlin 19 is covered from above on the tenon tube 51 protruding from the upper end surface of the roof truss column 182 , and the end of the purlin 19 is placed on the upper end surface of the roof truss column 182 . In addition, the pin hole of the purlin 19 is matched with the pin hole of the tenon tube 51 . In this state, the offset pin 101 is driven in from the side surface of the purlin 19 so as to penetrate through these pin holes. Thus, the purlin 19 is fixed to the tenon pipe 51 , and one purlin 19 is joined to the roof truss pillar 182 .

The tenon 532 of the purlin support fitting 53 covers the tenon hole 191 of another purlin 19 from above, and the end of the purlin 19 is placed on the top surface of the contact plate 531 of the purlin beam support fitting 53 . In addition, the pin hole of the purlin 19 is matched with the pin hole of the tenon part 532 . In this state, the offset pin 101 is driven in from the side surface of the purlin 19 so as to penetrate through these pin holes. Thereby, another purlin 19 is joined to the purlin support metal fitting 53, and the purlins 19 and the roof truss support 182 are joined.

Thus, if the joint part of a roof truss is formed using the purlin support metal fittings 53, sufficient strength can be given to the joint part of a roof truss, and a rational structural design can be performed. In addition, only the tenon hole 191, the bolt insertion hole 184, and the like may be formed in each member constituting the roof truss. In addition, the tenon part 532 of the purlin support metal fitting 53 can use the tenon hole provided in the roof truss as it is. Therefore, the processing of each member constituting the roof truss is completed only by simple processing with an inexpensive processing machine, and the processing time and cost can be reduced.

In addition, the purlin support metal member 53 is a part where the purlins 19 are perpendicular to each other. The lower side of the purlin 19 is at a position perpendicular to the side surface of the roof truss pillar 182 . In addition, when the purlin 19 is arranged over the upper end surface of the roof truss column 182 , the purlin 19 may be joined to the roof truss column 182 using the purlin support metal fitting 53 instead of the tenon tube 51 .

In addition, the above-mentioned roof truss is a "Japanese-style roof truss" composed of roof beams 18, roof truss pillars 182, and purlins 19, etc., but a "Western-style roof truss" as follows may also be used in the wooden building 1. The Western-style roof truss is a roof truss whose framework is a truss structure, and the framework of the roof part forms a roughly triangular frontal shape. For example, the roof truss shown in FIG. 1B is divided into two left and right parts by a central support (true beam) 196 hanging down from a ridge log 194 to a tie beam 195, and is configured so as to have a substantially right-angled triangle front shape. A tie beam 195 is arranged at the bottom of the truss structure, and an intermediate post (brace) 197 and a brace 198 are joined to the tie beam 195 . The tie beam 195 , the center pillar 197 , and the brace 198 are joined through lap joints and various metal fittings at these joint portions. The roof is supported by a roof truss constructed of trusses thus formed. In addition, in order to strengthen this truss structure, truss bending-proof parts, truss vibration-proof parts, etc. can also be installed appropriately.

The roof truss of this truss structure can reduce its own weight and increase the distance between fulcrums, so it is advantageous for setting a large-space living room in the wooden building 1, and can be preferably used. In addition, when the conventional wooden truss structure is adopted, there is a problem that the structure of the joint part of the pillar and the beam is complicated, but by using the roof truss of this embodiment, the above-mentioned members constituting the truss can be rationally formed. joints, so construction can be carried out without special skills.

(Gusset) (refer to Figure 18, Figure 19)

FIG. 18 is a perspective view showing an example of a gusset provided in the wooden building 1, and FIG. 19 is a plan view showing another example of the gusset.

In the wooden building 1, in addition to the above-mentioned structure, in order to prevent deformation caused by horizontal loads such as earthquake force and wind pressure, the horizontal structural surface formed by structural materials such as pillars 12, beams 14, and floor beams 141 is reinforced. of various components.

As a method of reinforcing the horizontal structural surface, firstly, a method of fastening a surface material such as a structural laminate of an appropriate size to the upper surface of the horizontal material at the corner of the horizontal structural surface perpendicular to the horizontal material such as the floor beam 141 is mentioned. Thereby, the corner part of the horizontal structure surface can be fixed, and rigidity can be improved.

In addition, there is also a method of providing gussets at the corners perpendicular to the horizontal members as reinforcing members of the horizontal structural surface. The gussets are arranged so as to form a corner at 45° with respect to the column height of the upper floor and the height of the eaves beams, for example.

The gusset 6A shown in FIG. 18 is a metal member made of steel, and is formed by press working a steel plate. The illustrated gusset 6A has, as a whole, an elongated boat shape forming a groove shape. This gusset 6A has attachment portions 61 at both ends. The mounting parts 61 are each bent so as to follow the corners of the horizontal structural surface, and are formed as inclined surfaces with the front end side raised.

As shown in FIG. 1A , the gusset 6A is provided, for example, at a corner of a horizontal structural surface formed by the roof beam 18 and the eaves stringer 185 . The mounting parts 61 at both ends of the gusset 6A are fastened to the inner surfaces of the roof girder 18 and the eaves stringers 185 with bolts or the like. As a result, the horizontal structural surface has predetermined earthquake resistance and wind resistance, and the strength of the wooden building 1 can be increased.

In addition, the gusset 6B shown in FIG. 19 is comprised from the gusset main body 63 and the fixing tool 65 provided in the both ends of this gusset main body 63. As shown in FIG. The gusset main body 63 is a steel metal member formed of a hollow round rod. Bolt-shaped shaft portions 631 are provided at both ends of the gusset main body 63 . The shaft portion 631 is welded to both ends of the gusset main body 63 and extends on its axis.

The fixture 65 includes a mounting surface 651 and one or two holding surfaces 652 for holding the shaft portion 631 of the gusset main body 63 . The mounting surface 651 has pin holes and bolt holes not shown, and is fixed in contact with the inner surface of the horizontal member forming the horizontal structural surface. In addition, in the fixing tool 65 , each shaft portion 631 of the gusset main body 63 is engaged with the holding surface 652 , so that nut fastening can be performed.

As shown in FIG. 19 , gussets 6B are provided obliquely at the corners of the rectangular horizontal structural surface formed by the roof beams 18 and 18 erected in parallel and the eaves stringers 185 .

In this case, on the gusset main body 63 , first, the fixing member 65 is brought into contact with the inner surfaces of the roof beam 18 and the eaves stringer 185 , and is temporarily fixed with the bolt 102 . The retaining surfaces 652 and 652 of the fixing member 65 in the center where the two gusset main bodies 63 engage are extended inwardly from both end edges of the mounting surface 651 . Next, the mounting surface 651 of the fixing member 65 is fixed with screws 106 . Thereafter, the bolts 102 are fastened, so that the fixing parts 65 are fastened and connected to the roof beams 18 or the eaves stringers 185 respectively. These fixtures 65 may be installed in advance at a factory or the like.

Next, the gusset main body 63 is mounted on the holding surface 652 of the fixing pieces 65 , 65 . At this time, hook the two ends of the gusset main body 63 into the locking grooves provided on the holding surface 652 and temporarily fix them, and after adjusting the position, tighten the nuts on the shaft portion 631, thereby tightening them with the fixing members 65, 65. Solid link. The angle braces 6B erected in this way elastically support the horizontal structural surface of the wooden building 1 within its resistance range. Accordingly, deformation in the horizontal direction of the wooden building 1 due to earthquakes and wind pressure can be prevented.

(Joist supporting hardware) (refer to Figure 1, Figure 20)

FIG. 20 is an explanatory view showing a junction between joists 143 and floor beams 141 of wooden building 1 . Each joist 143 of the wooden building 1 shown in FIG. 1A is supported by the side surface of the floor beam 141 via the joist support metal fitting 71. As shown in FIG.

The joist support metal member 71 is formed by bending a metal plate. The illustrated joist support metal fitting 71 includes a stand portion 712 supporting the lower surface of the joist 143 , a pair of side pieces 713 standing up from both ends of the stand portion 712 , A pair of mounting pieces 714 extend out. A plurality of pin holes 715 are provided in the side piece 713 and the mounting piece 714 . The joist support metal member 71 fixes the mounting piece 714 to the side surface of the floor beam 141 using fixing means such as screws.

For example, the joists 143 are made of wooden angled materials, laminated materials, etc., and their lengths are formed to be slightly shorter than the arrangement intervals of the floor beams 141 . The joists 143 are arranged in plural rows with a gap slightly larger than the width of the floor beams 141 .

As shown in FIG. 20 , joist support metal fittings 71 for supporting ends of the joists 143 are attached to upper side surfaces of the floor beams 141 in the longitudinal direction at intervals corresponding to the intervals of the joists 143 . Joist support metal parts 71 are also attached to mutually opposing sides of the floor beam 141 .

With respect to the floor beams 141, the joists 143 are put between the side surfaces of the adjacent floor beams 141, and the both ends of the joists 143 are directed from above to the support parts 712 and the side pieces 713 of the metal fittings 71 supported by the joists. The enclosed space is partially inserted. The joist 143 is sandwiched by the side pieces 713 from both left and right sides, and is supported by the joist supporting metal 71 . In addition, movement in the horizontal direction of the joists 143 , that is, the lengthwise direction of the floor beam 141 is restricted. The joists 143 are fixed by screws or the like through the screw holes 715 of the side pieces 713 .

In addition, the upper end part of the side piece 713 may spread in the direction which mutually separates, and may form so that insertion of the joist 143 may be easy. Moreover, it is preferable that both ends of the joist 143 are mounted on the seat part 712 of the joist support metal fitting 71 via a vibration-proof material. As the anti-vibration material, for example, plate-shaped anti-vibration rubber can be used. Thereby, the end part of the joist 143 is anti-vibration-supported by the joist support metal fitting 71. As shown in FIG.

In this way, in the wooden building 1 , the joists 143 are interposed between the side surfaces of the adjacent floor beams 141 via the joist support metal fittings 71 provided on the floor beams 141 . A floor covering is laid on the floor beams 141 and the joists 143 . A floor surface previously integrated at a factory or the like may be laid on the floor beams 141 provided with a plurality of pieces. In this case, the floor surface is comprised by the floor board|substrate material which consists of laminated boards for structures, joists 143, a vibration-proof material, etc., and each joist 143 is supported by the joist support metal fitting 71. The joist support metal fitting 71 can be effectively used in the case where the joint portion of the floor beam 141 and the joist 143 has no support point.

(reinforcing metal piece) (refer to Fig. 21A, Fig. 21B)

In the wooden building 1 , a channel 17 for various piping, wiring, and the like may be inserted through a horizontal member such as a floor beam 141 . In this case, it is necessary to provide passage holes (through holes) 157 in the beam width direction in the beam 14 . There is a possibility that the strength of the beam 14 provided with the passage hole may be lowered due to the breakage of the section. Therefore, in order to supplement the strength of the beam 14 in the wooden building 1 , reinforcing metal fittings 73 are provided around the passage holes.

FIG. 21A is a perspective view showing an example of a reinforcing metal fitting, and FIG. 21B is a perspective view showing another example of a reinforcing metal fitting.

The additional metal member 73 is made of a steel plate, a stainless steel plate, or the like with a thickness of about several mm. The reinforcing metal member 73 shown in FIG. 21A is formed with a circular opening 731 along the periphery of the cylindrical passage hole. In addition, the reinforcing metal piece 73 shown in FIG. 21B is formed with a substantially U-shaped opening 731 in a front view along the periphery of the channel hole.

These reinforcing metal fittings 73 are formed with a plurality of screw holes not shown. The reinforcing metal piece 73 is fixed to the side of the beam 14 using screws 106 .

Alternatively, a spot facing hole and a bolt insertion hole may be formed on the side of the beam 14 in advance, and a knob protrusion may be provided on the back of the reinforcing metal fitting 73 to fit into the beam 14 and be fixed by bolt and nut connection.

With such a reinforcing metal piece 73, the strength of the beam 14 provided with the passage hole can be supplemented. Therefore, when the passage holes are provided in the beams 14, it is not necessary to increase the cross-sectional dimension of the beams 14 more than necessary, and the degree of freedom in design of the wooden building 1 and the economy can be improved.

-Resistance elements-

In the wooden building 1 constructed as described above, a surface material as a resistance element is arranged between the beams 14 and the beams 14 of the upper and lower floors, or between the beams 14 and the foundation 16 according to the required strength and the like. There are various types of surface materials as resistance elements, and constitute a part of main structural members such as pillars 12 and beams 14 . However, the size of the resistance element, the size and arrangement of each component are not limited to those shown below, and are appropriately determined in accordance with other design elements of the structural body.

The main body of the structure reinforced by the surface material composed of resistance elements is superior in strength and rigidity compared to conventional general wooden buildings constructed using natural materials. Therefore, the degree of freedom in designing the configuration of the pillars 12 and the resistance walls increases, and reinforcement components such as diagonal pillars and corner braces can be reduced, and it is also easy to form a large-span space and an opening with a large front width of the building.

(resistance wall) (refer to Figure 22)

In the wooden building 1 , the resistant wall is an earthquake-resistant element of the structural main body using laminated timber with a middle section or less. The resistance wall is arranged in the structural plane between the pillars 12 or the beams 14 and fixed integrally with the pillars 12 or the beams 14 .

FIG. 22 shows an example of the resistance wall 81, and is a front view showing a state in which it is arranged between the upper and lower beams 14 in the second-floor portion. In addition, the resistance wall 81 is arranged between the beam 14 and the foundation 16 in one layer.

The resistance wall 81 has a rectangular frame body 84 composed of upper and lower crosspieces 145 , left and right side columns 124 of the resistance wall 81 , a central pilaster 125 , and two middle columns 34 disposed between the side columns 124 and pilasters 33 . In this frame body 84 , the crosspiece 145 is joined to the side column 124 in a penetrating manner (crosspiece penetration). The joint part of the side column 124 and the cross piece 145 may be the form reversed from the example (pillar piercing).

The size of the resistance wall 81 is, for example, a wall length of 2000 mm×a height (between beams) of 2610 mm. The beam 14 is a middle-section laminated lumber with a cross-section of 120 mm (beam width) × 270 mm (beam thickness), the side column 124 is made of a quadrilateral material with a cross-section of 120 mm, the wall column 33 is made of a material with a cross-section of 120 mm × 45 mm, and the inter-column 34 is Made of materials with a cross-section of 120mm×30mm.

The frame body 84 is joined to the upper and lower beams 14 at the upper and lower ends of the side columns 124 , respectively. For this joining portion, for example, a joint metal fitting 3E and a punch 101 shown in FIGS. 11 and 12 can be used. The type of joining metal is appropriately set according to the required pull-out resistance. In addition, when the lower part of the frame body 84 is directly connected to the foundation 16 instead of the beam 14 , the anchor bolts 104 can be embedded in the foundation 16 and joined via the above-mentioned leg fittings 4 .

On the frame body 84, a face material 85 is constructed on a single-sided or double-sided nail. In the example shown in FIG. 22, the structural surface material 85 is nailed on one side, and the gypsum board is fixed on the other side with screws.

The structural surface material 85 is, for example, a structural laminate with a thickness of 7.5 mm or more, and the distance between the side columns 124, pilasters 125, crosspieces 145, and beams 14 is 60 mm or 120 mm. In addition, the distance between the relative columns 126 is 120 mm and fixed with nails 107. . In this way, the nailing distance of the resistance wall 81 to the main parts of the frame body 84 (the cross piece 145 , the side column 124 , and the pilaster 125 ) is reduced to about 60 mm with respect to the nailing distance of the surface material 85 for the fixing structure.

In the joint portion of the column head, column leg and beam 14 of the frame body 84, by using the joint metal fitting 3E or the like ensuring high strength to strengthen the joint portion, a wall magnification of about 5 to 8 times can be actually obtained.

(Resistant wall panel) (refer to Figure 23)

The above-mentioned resistance wall 81 can also be installed in the wooden building 1 by using a pre-panelized resistance wall panel.

Fig. 23 is a perspective view showing an example of a force-resistant wall panel. The frame body 84 of the resistance wall panel 82 is formed by assembling the upper and lower crosspieces 145, side columns 124, pilasters 125, and spacer columns 126 into a rectangular frame, and joining these components to each other. A force-resistant wall panel 82 is formed on at least one surface of the frame body 84 by fixing the structural face material 85 with nails.

The resistance wall panel 82 is arranged between the upper and lower beams 14 of the wooden building 1 , or between the beams 14 and the foundation 16 . The frame body 84 and the beam 24 are joined using a metal joint 3E or the like as shown in FIG. 12 . Thereby, labor saving at the construction site can be achieved, and a resistance wall of a wooden building can be formed with high precision and in a short time.

(Space resistance wall) (refer to FIG. 24A, FIG. 24B)

As the partition wall of the wooden building 1 , a partition resistance wall may be arranged between the plurality of pillars 12 bearing the load of the beam 14 .

FIG. 24A is a front view showing the appearance configuration of the partition resistance wall, and FIG. 24B is a perspective view showing an example of a resistance panel of the partition resistance wall.

The interval resistance wall 87 shown in FIG. 24A is arranged between the beam 14 and the foundation 16 , and is formed by embedding a resistance panel 88 between two pillars 12 . As shown in FIG. 24B , the resistance panel 88 is formed by combining a plurality of vertical members 882 and horizontal members 883 in a grid pattern inside a panel frame 881 made of angle materials. The vertical members 882 and the horizontal members 883 are each provided with notches at a plurality of positions having a depth approximately half of the thickness. Thereby, a plurality of vertical members 882 and horizontal members 883 can be overlapped and joined together to form a grid.

A pair of upper and lower frames 872 are horizontally erected between the two pillars 12 . A base material with an inverted L-shaped cross section is added to the lower surface of the upper frame material 872 , and a base material with an L-shaped cross section is added to the upper surface of the lower frame material 872 . In addition, base materials having an L-shaped cross section are added to face each other on the inner surface in the longitudinal direction of the pillar 12 . As a result, a recess (not shown) to fit around the resistance panel 88 is formed inside the pillar 12 . The resistance panel 88 engages and fits the panel frame 881 into the recess formed between the two pillars 12 . Fasteners such as screws are screwed into the junction between the panel frame 881 and each base material, and fixed. The decorative material 874 is concealed at the joint portion between the panel frame 881 and the base material, and the joint strength is improved.

This partition resistance wall 87 can be formed by assembling at a construction site as a state where the resistance panel 88 is assembled in advance at a factory. Therefore, since the resistance wall 88 can be produced as a whole in a factory, there is an advantage that there is little variation in strength performance. In addition, only a simple installation operation such as fitting the resistance panels 88 between predetermined columns 12 and fixing them with screws or the like can be completed at the construction site, and partition walls can be easily formed. In addition, the partition resistance walls 87 ensure lighting and ventilation due to the grid-like appearance, and have high designability.

The partition resistance wall 87 can easily replace the resistance panel 88 when a part of the resistance panel 88 is damaged or stained. That is, the resistance panel 88 can be easily detached from the panel frame 881 by removing the surrounding decorative material 874 and screws. Even if the resistance panel 88 is taken off, there will be no damage on the structural materials such as the pillar 12 and the beam 14, and it is not necessary to take off the interior paving materials of the ceiling and the floor. Therefore, at the position where the resistance panel 88 is removed, a new resistance panel 88 can be fixed and exchanged using the same construction process as described above.

In the wooden building 1, when an opening such as a high window on the back facing the shaft space is provided, high resistance to the large wind pressure acting on the opening is exerted, and the opening of the opening is The configuration of the shaft opening that is excellent in relaxation and pattern design will be described.

FIG. 25 is a schematic elevation view showing an example of the appearance of the wooden building 1, and FIG. 26 is an exploded perspective view showing the skeleton structure of the shaft opening of the wooden building 1 viewed from the outside.

The wooden building 1 shown in FIG. 25 is a two-story building, and a shaft space on the second floor level is provided inside the house. On the outer wall facing the shaft space, a vertically long shaft opening (hereinafter referred to as opening 9 ) extending over about the second floor is provided. As shown in FIG. 26 , the opening 9 is equipped with a wind-resistant column 91 , a reinforced concrete foundation 16 , eaves stringers 185 arranged at the uppermost part of the main frame, and inter-column tie beams 144 constituting the outer wall frame.

A plurality of wind-resistant columns 91 are arranged on both sides and inside of the opening 9 (for example, four in total in this embodiment). The wind-resistant column 91 is formed of a laminated material having a rectangular cross-section of, for example, a major axis of 360 mm×a minor axis of 120 mm. This laminated material is arranged so that the major axis direction of the cross section is perpendicular to the opening surface to form the wind-resistant column 91 . In addition, the cross-sectional size of the wind-resistant column 91 is not an exemplary limit, and the long-axis size is about twice or more than the short-axis size, preferably 2.5 to 3.5 times, which is ideal in terms of strength.

The wind-resistant column 91 is continuously continuous with one material throughout the second floor. The column leg of the wind-resistant column 91 is fixed on the foundation 16 made of reinforced concrete using the column leg metal fitting 4 shown in FIG. 15 or FIG. The column head of the wind-resistant column 91 is joined to the eaves stringer 185 through the beam-through form in this example via the beam support metal fittings 2 shown in FIG. 2 or FIG. 3 .

The wind-resistant columns 91 are connected to each other by a column connection material 93 . The column connection material 93 is a member whose cross-sectional dimension is smaller than that of the wind-resistant column 91 . The illustrated column connecting material 93 uses a laminated material having a cross-section equal to or smaller than that of the inter-column tie beam 144 . The column connection material 93 is joined to the side surface of the wind-resistant column 91 through an appropriate beam support metal fitting 2 . The installation height of the column connection material 93 does not affect the height of the floor frames installed on the upper and lower floors, and an appropriate intermediate position in the height direction of the wind-resistant column 91 can be set.

With respect to the opening 9, since the strong axis direction of the wind-resistant column 91 is perpendicular to the opening surface, high resistance against wind pressure acting on the opening surface is exhibited. Thereby, it is possible to design an enlarged opening 9 with a sense of relaxation. The height of the openings 9 can be formed in three or more stages as long as the cross-sectional dimensions, arrangement intervals, and the like of the wind-resistant columns 3 are appropriately set.

In addition, although the window frames and the like attached to the opening 9 are omitted from illustration, they may be installed at any position on the outside, inside, and depth of the wind-resistant column 91 . The wind-resistant column 91 made of laminated materials can be used both indoors and outdoors. In addition, appropriate finishing materials may be applied to the surface of the wind-resistant column 91 exposed on the inside or outside of the house.

As described above, the wooden building 1 according to the present embodiment can be constructed with higher strength and a higher degree of design freedom by including the above-mentioned structures instead of the conventional wooden frame construction method and the frame assembly wall construction method. In addition, as shown in the present embodiment, it is possible to provide new specifications for frame members of the wooden building 1, and to rationalize joints with each member. Thereby, the efficiency of the construction work of the wooden building 1 and the improvement of constructability can be aimed at, and the construction method which does not depend on a special skill can be realized. In addition, according to the above-mentioned structure, in the wooden building 1, the degree of freedom of room layout and opening arrangement is greatly improved, and it can also be applied to a space design with high pattern design that emphasizes the strength of wood in a large space, and it is possible to build A building with excellent thermal insulation performance and ventilation performance.
