2. Description of the Related Art In a wooden framed building, bracing, hole-down hardware, blade bolts, and the like are typically used as a reinforcing structure for improving strength such as earthquake resistance. The streak difference is that a substantially vertically rectangular area formed by the upper and lower beams and the base and the left and right pillars is crossed in an approximately X shape between the upper and lower left and right corners, and attached using nails or the like. Was. The hole-down hardware is fastened to the ends of the left and right pillars using bolts or the like, and the haute plate bolts are used near the upper ends of the left and right pillars. Conventionally, such studs, hole-down hardware, feather bolts, etc. have been used to improve the seismic resistance of wooden buildings so that they can withstand the pull-out force applied to the columns, while at the same time concentrating the power on poles such as columns and beams. By avoiding this, buckling of columns and beams is prevented, and reinforcement and improvement of the overall strength are achieved.

[0003]

[Problems to be solved by the invention] << Each problem >>
By the way, in such a conventional example, the following problem has been pointed out. First of all, it is pointed out that it is not easy to accurately install the crossing between the upper and lower right and left corners, crossing in a substantially X-shape, requiring skill, and the mounting technique will result in a difference in overall strength. there were. For streaks, hole-down hardware, and feather plank bolts, the ends of the wooden pillars to be fastened may have many holes that may be cracked due to the concentrated fastening of these many members. It was pointed out that the concentration reduced the strength of the pillars and weakened the pillars. , Struts, hole-down hardware, and wing plate bolts are concentrated, competitive,
They are mounted and fixed at the same location. Therefore, since they interfere and interfere with each other, it is extremely difficult to accurately mount and fix each of them, and when a load is applied due to an earthquake or the like, for example, hole-down hardware is easily damaged. Was pointed out. If the braces are damaged, there is a risk that the wooden building will collapse.

[0004] In many cases, the pillar has a back crack (a crack extending up and down the back of the pillar and penetrating to about half the wall thickness). Therefore, if a hole-down hardware is fastened to such a pillar using a bolt, etc., the bolt will be inserted into the back crack, and the hole-down hardware will rattle, and the fastening of the hole-down hardware will be inaccurate. As a result, hole-down hardware sometimes stopped functioning. As a streak, wooden ones are often used. Therefore, cracking, insect biting, corrosion, use of a desiccant,
The type of cedar and cypress, etc., were adversely affected, and in some cases, they could not function as streaks. Was particularly vulnerable to repeated tremors. In other words, due to the reinforcement structure using bracing, hole-down hardware, and feather board bolts, the wooden building is rigidly and rigidly assembled as a whole, and is poor in stickiness, bending, and flexibility. The risk of breakage and collapse was pointed out.

<< Operation >> The present invention is configured as described above, and is as follows. Claims 1, 2, 3, 5
Is composed of two upper and lower horizontal members, two left and right vertical members, and a diagonal member, and is formed of a substantially vertically long square-shaped frame. The horizontal member, the vertical member, and the diagonal member are welded between the ends, and the L-shaped angle hardware and the square tube hardware are selectively used. For example, a rectangular tube hardware is used as a horizontal member, and an L-shaped angle metal member is used as a vertical member and a diagonal member. However, it is also possible to use an L-shaped angle hardware or a rectangular metal hardware. The reinforcing hardware is used to reinforce a wooden framed building, and is disposed around the periphery of the space formed by the beams, bases, and columns of the wooden building, and the horizontal members are integrated with the beams and the base. The longitudinal members are fixed to the pillar integrally.

Therefore, since the reinforcing hardware is made of a frame-shaped integral body, it can be easily fastened to a pillar, a beam, or a base of a wooden building, there is no difference in mounting technology, and there is little deformation or loosening in the event of an earthquake or the like. The horizontal members reinforce the beams and the base, the vertical members function as hole-down hardware, reinforce the columns, and the diagonal members function staggeredly. Therefore, in the event of an earthquake or the like, the force flows smoothly without concentrating on the local portions of the pillars, beams and base, and the wooden building has a stable strength. This reinforcing metal is made of pillars, beams,
Since it is fixed on the base, it does not concentrate on the ends of the pillars, unlike conventional struts or hole-down hardware, preventing the occurrence of cracks due to the concentration of the fixing and preventing a drop in strength. Is done. This reinforcing metal is dispersed and fastened. The fastening is concentrated at the end of the column and does not interfere with each other. It is hard to be damaged or broken even when a load is applied, and functions accurately. This reinforcing metal is dispersed and fastened, and the fastening does not concentrate at the end of the pillar, so if there is a crack in the pillar, the fastening may concentrate on the crack and uncertainty. However, the vertical members and the like are securely fastened and exert their functions. Since this reinforcing metal is made of metal, the horizontal member, the vertical member, and the diagonal member reliably function without being adversely affected by cracks, insect bites, corrosion, use of desiccants, types, and the like.

[0013] The reinforcing hardware is an L-shaped angle hardware, that is, an L-shaped angle hardware capable of exhibiting stickiness, bending, softness, elasticity and deformability and easy to be fixed and integrated, and a square tube hardware excellent in rigidity and strength. Are used selectively. For example, a rectangular metal member is used as the horizontal member that is integrated with the beam or the base and the force is easily concentrated, and an L-shaped angle member is used as the vertical member or the diagonal member that is integrated with the column and acts on the tensile or compressive force The L-shaped angle hardware and the rectangular tube hardware are selectively used, for example, by using hardware. Therefore, this reinforcing metal is
The vertical members and diagonal members easily work together with the pillars, beams and foundation of the wooden building, and integrate well with the wooden building. Accordingly, the wooden building is not hardened and rigid as a whole, but is reinforced while maintaining appropriate tenacity, bending, and flexibility. By using these reinforcing hardware, a well-balanced and stable reinforcing structure can be obtained for a wooden building, the overall strength of the wooden building is improved, the seismic resistance is improved, and the strength of the local building is improved. Concentration is avoided and buckling is also prevented. In addition, the reinforcing metal has a frame shape combining horizontal, vertical, and diagonal members, and has a simple configuration in which an L-shaped angle metal and a square tube metal can be used properly.
Construction is completed by fastening to the base, and workability is excellent.

According to a fourth aspect of the present invention, the diagonal members are arranged crosswise, and a connection reinforcing plate is interposed at a lower corner portion, and is welded to a lower end of the vertical member and a lower end of the diagonal member to be placed on the horizontal member. It is mounted and fixed to the base using anchor bolts. Therefore, when an upward tensile force is applied, the vertical members and the diagonal members are reinforced by the welded connection reinforcing plates to prevent damage, and the horizontal members are embedded in the vertical members and the diagonal members. There is no danger of damage. According to the sixth aspect, the diagonal members are arranged crosswise, and the middle crosspiece using the L-shaped angle hardware is disposed laterally at the center, and is welded to the vertical members and the diagonal members. Thus, the presence of such a middle cross member allows the diagonal member to be received and held by the vertical member and the pillar, thereby ensuring strength and preventing buckling. In addition, due to the presence of such a middle cross member, the central portion of the vertical member is pressed to the column side, so that the vertical member is difficult to separate from the column, and is securely fixed integrally. According to the seventh aspect, since the hole-down hardware is used together and fixed to the end of the pillar, the pillar is further reinforced, and the pillar is prevented from being pulled out from the base or the beam in the event of an earthquake or the like. According to the eighth aspect, the hole-down hardware is further fixed to the base or the beam using the anchor bolt or the like, so that it is further strongly fixed.

In the illustrated example, the diagonal members 6 cross each other in a substantially X-shape and are disposed between the corners of the upper, lower, left and right horizontal members 4 and the vertical members 5, but other various arrangement examples are also possible. For example, an example in which it is arranged diagonally only on one of the right and left, an example in which it is welded to a central position between the upper and lower left and right horizontal members 4 and the vertical member 5 as a substantially rhombus, or a substantially broken line between the left and right vertical members 5 Examples in which welding is performed so as to reciprocate sequentially are also possible.

The reinforcing hardware 1 is used for
The space formed by the upper and lower beams E and the base C of the wooden building A and the left and right pillars D (in the case of the first floor, the space formed by the upper beam E, the lower base C, and the left and right pillars D, (In the case of the second floor or more, the space formed by the upper and lower beams E and the left and right pillars D) is arranged on the peripheral edge portion, and the cross members 4 are integrally fixed to the beams E and the base C ( In the case of the first floor, the upper cross member 4 is fixed to the beam E, the lower cross member 4 is fixed to the base C, and in the case of the second floor or more, the upper and lower cross members 4 are respectively upper and lower. The vertical member 5 is fixed to the column D. That is, FIG.
In the illustrated examples shown in FIGS. 2, 3, 4, and 5 (1), the lower cross member 4 is fixed to the base C by the anchor bolt 2 or the screw bolt 3. . Left and right vertical members 5

In other words, this reinforcing hardware 1
Of course, it is also possible to use these together.

In the reinforcing metal member 1, as the horizontal member 4, the vertical member 5, and the diagonal member 6, the L-shaped angle metal member 9 and the rectangular cylindrical metal member 1 are used.

In the reinforcing metal member 1, the L-shaped angle metal member 9 and the rectangular tube metal member 10 are selectively used as the horizontal member 4, the vertical member 5, and the diagonal member 6 in various combinations according to their properties. It becomes. For example, in the illustrated example, a rectangular tube hardware 10 is used as the horizontal member 4, and an L-shaped angle hardware 9 is used as the vertical member 5 and the diagonal member 6. Of course, other various combinations are possible without depending on the illustrated example. For example, the upper cross member 4 may use an L-shaped angle hardware 9, and further, the upper cross member 4 may further include a cross member 4 and a vertical member 5. , As diagonal 6
In all cases, construction using an L-shaped angle hardware 9 or square tube hardware 10 is also possible. The reinforcing hardware 1 first has such a configuration.

<< Other Configurations of Reinforcement Hardware 1 >>
The middle crosspiece 11 will be described. In the reinforcing hardware 1 of the example shown in FIG. 1, FIG. 2, FIG. 3, and FIG. 5 (2) and the like, the diagonal members 6 are arranged in a substantially X-shaped cross, and furthermore, the metal The middle crosspiece 11 is arranged at the center side. The middle crosspiece 11 to be stopped is welded to the vertical member 5 and the diagonal member 6, and an L-shaped angle hardware 9 is used in the illustrated example. The left and right ends of the middle crosspiece 11 arranged at the center side are welded to the left and right vertical members 5, respectively, and are also welded to the diagonal members 6 at the center. When the disposition of the diagonal members 6 is different from that in the illustrated example, that is, when the diagonal members 6 are disposed without forming a substantially X-shape, the welding portion between the middle crosspiece 11 and the diagonal members 6 also corresponds.

Are fixed to the upper and lower ends of the left and right columns D via the vertical members 5, respectively. And each hole down hardware 13
In the example of FIG. 7 (only the left corner portion is shown in FIG. 7), the base C and the foundation B or the beam are connected via the cross member 4 by using the anchor bolt 2 or the through bolt 7. E
It is fixed to. That is, in the example of FIGS. 1 and 2, the hole-down hardware 13 is not used.
In the example, the hole-down hardware 13 is used. That is, the hole-down hardware 13 is not indispensable, but may be used as needed according to the specifications such as the dimensions of the horizontal member 4, the vertical member 5, the diagonal member 6 and the like, and if necessary, to further improve the strength. Sometimes. For example, regardless of the illustrated example, when the rectangular tube hardware 10 is used as the vertical member 5, the use frequency of the hole-down hardware 13 seems to be low. When the pillar D is a through pillar, that is, when the pillar D on the first floor and the pillar on the second floor is a single continuous row regardless of the illustrated example, the position of the pillar D where the upper and lower sides of the beam E are regarded as ends respectively, Hole-down hardware 13 is often used.

In the example of FIG. 3, the hole-down hardware 13 is connected to the end of the column D (the end position near the beam E in the case of the through column) through the bolt hole of the vertical member 5 and the through bolt 7.

That is, the hole-down metal member 13 is fixed to the cross member 4 and the beam E by the through bolt 7 using the vertical hole formed therein.

<< Regarding the Operation and the Like >> The reinforcing hardware 1 of the wooden building A according to the present invention is configured as described above. Then, it becomes as follows. The reinforcing metal member 1 is made of an integrated body composed of two upper and lower horizontal members 4, two left and right vertical members 5, and a diagonal member 6 arranged in a cross in a substantially X shape in the illustrated example. And a substantially vertically long rectangular frame shape. Cross member 4,
The vertical member 5 and the diagonal member 6 are made of metal, and their ends are welded to each other.
They are selectively used according to their properties (see FIGS. 1, 2, 3, and 5 (1), etc.). For example, in each of the illustrated examples, the rectangular tube hardware 10 is used as the horizontal member 4 and the L-shaped angle hardware 9 is used as the vertical member 5 and the diagonal member 6, but the horizontal member 4, the vertical member 5, and the diagonal member 6 are used. , The L-shaped angle hardware 9 and the square tube hardware 10 can be used in other various combinations other than the illustrated example, and the L-shaped angle hardware 9 or the square tube hardware 10 can be used for all of them. .
The reinforcing hardware 1 is used as a reinforcing hardware 1 for a wooden framed building, and the upper and lower beams E and the base C of the wooden building A are used.
And the left and right pillars D are arranged at the periphery of the space formed by the upper and lower cross beams 4 and the upper and lower wooden beams E of the wooden building A.
And the left and right vertical members 5 are integrally fixed to the left and right wooden pillars D of the wooden building A (see FIGS. 1, 2 and 3). .

Therefore, since the reinforcing metal member 1 is formed of an integral member having a frame shape (particularly, see FIG. 5 (2)).
It is easy to fix and attach to the pillar D, the beam E and the base C on the wooden building A side, there is little difference due to the attaching technique, and after the attaching, there is little deformation or loosening in the event of an earthquake or the like. And the cross member 4 reinforces the beam E and the foundation C of the wooden building A which are integrally fixed. The vertical members 5 function as a continuous hole-down hardware in the vertical direction, and reinforce the pillar D of the wooden building A that is integrally fastened, and the pillar D is used as the base C or the foundation B (in the case of the second floor, Ensure that it is not pulled out of beam E).
The diagonal member 6 functions in a conventional manner. By these,
The reinforcing hardware 1 is a wooden building A such as a pillar D, a beam E, and a base C.
The whole is reinforced (see FIGS. 1, 2 and 3). (Note that, as in the examples of FIGS. 3 and 7,
3 can also be added). Therefore, in the event of an earthquake or the like, the force does not concentrate on the columns D, the beams E, and the bases of the wooden building A, and the applied force flows smoothly, so that the wooden building A has a stable strength. .

In this reinforcing metal member 1, the horizontal member 4 and the vertical member 5
The wooden building A is dispersed and fixed to the pillar D, the beam E, and the base C of the wooden building A (see FIGS. 1, 2, and 3). Therefore, unlike the streaking and hole-down hardware of this type in the related art, the fastening is not concentrated on the end of the pillar D, and the occurrence of a crack due to the fastening concentration on the end of the pillar D is also prevented. For example, when the hole-down metal 13 is used in combination as in the examples of FIGS. 3 and 7, this advantage is slightly reduced. In this metal fitting 1, horizontal members 4 and vertical members 5 are dispersed and fixed to pillars D, beams E, and bases C on the wooden building A side. Therefore, they do not interfere with each other (see FIGS. 1, 2 and 3). Therefore, since the horizontal member 4, the vertical member 5 (and, of course, the diagonal member 6) and the like are accurately fastened and fixed, even if a load is applied due to an earthquake or the like, the members are hardly damaged or broken, and their functions are accurately exhibited. In this reinforcing metal 1, the horizontal member 4 and the vertical member 5 are made of a wooden building A.
It is distributed and fixed to the side columns D, beams E, and the base C, and the fixing does not concentrate on the ends of the columns D (see FIGS. 1, 2, and 3). Therefore, when the back crack exists in the column D, the fastening does not concentrate on the back crack and the fastening does not become uncertain.
The vertical members 5 and the like are less likely to be affected by the back crack, are securely fastened, and exhibit their functions. The metal reinforcement 1 is made of metal such as steel. Therefore, the horizontal member 4, the vertical member 5, and the diagonal member 6 reliably exhibit their functions without being affected by cracks, insect bites, corrosion, use of desiccants, types, and the like.

The reinforcing metal member 1 is an L-shaped angle metal member 9, that is, an L-shaped angle metal member capable of exhibiting stickiness, bending, softness, and expansion and contraction, being easily bent, having a restoring force, and being easily fixed and integrated. The most characteristic feature is that the metal pipe 9 and the rectangular pipe metal piece 10 having excellent rigidity and strength are selectively used according to their properties (see FIGS. 1, 2 and 3). Therefore, for example, as the cross member 4 which is integrated with the beam E and the base C on the wooden building A side and the force is likely to be concentrated, the rectangular tube hardware 10 is adopted, and the pillar D on the wooden building A side is used. Longitudinal members 5 that are often subjected to tensile or compressive force, such as being integrated
It is conceivable that an L-shaped angle hardware 9 is used as the oblique member 6. Thus, the reinforcing hardware 1 allows the horizontal member 4, the vertical member 5, and the diagonal member 6 to easily work together with the pillar D, the beam E, and the base C on the wooden building A side. And well integrated. That is, the wooden building A is not stiffly and rigidly assembled as a whole, but is reinforced while maintaining appropriate tenacity, bending, and flexibility.

With these,,,, etc.,
When the reinforcing hardware 1 is used, a well-balanced and stable reinforcing structure is obtained for the wooden building A, and the overall strength is greatly improved. Therefore, the columns D, beams E, and base C of the wooden building A endure the pull-out force, the seismic resistance is improved, the concentration of the force on the local part is avoided, and the buckling is also prevented. In addition, the reinforcing hardware 1 has a frame shape in which the horizontal member 4, the vertical member 5, and the diagonal member 6 are combined, is easy to handle, and has a simple configuration in which the L-shaped angle hardware 9 and the square tube hardware 10 are selectively used. Consisting of The work is completed by fixing to the pillar D, the beam E, and the base C on the wooden building A side, and the workability is excellent.

<< Regarding Other Functions >> Further, the reinforcing hardware 1 of the wooden building A shown in FIG. 6 has the diagonal members 6 arranged in a substantially X-shaped cross, and the metal fittings are provided at the lower left and right corners. A mouth reinforcing plate 12 is interposed. Each of the mouth reinforcing plates 12 is welded to the lower end of the vertical member 5 and the lower end of the diagonal member 6 and is mounted on the horizontal member 4, and the wooden building A side To the base C and the foundation B using the anchor bolts 2. Thus, when an upward tensile force acts upon an earthquake or the like, the lower horizontal member 4, that is, the extremely thin horizontal member 4 made of the square metal fitting 10 and having a thickness of about 2 mm to 3 mm becomes the upper vertical member 5, The situation where it breaks into the lower end of the diagonal 6 and breaks
This is avoided by the interposed connection reinforcing plate 12.
Further, the vertical members 5 and the diagonal members 6 are also welded to the connection reinforcing plate 12 and reinforced, so that the damage is prevented.

1, 2 and 3 is a reinforcing metal fitting 1 of a wooden building A, in which diagonal members 5 are arranged in a substantially X-shaped cross, and a metal middle cross member 11 is provided beside the center. The middle crosspiece 11 uses an L-shaped angle metal fitting 9 and is welded to the vertical member 5 and the diagonal member 6. The diagonal 6 is the middle cross 1
1, and is firmly received and held by the vertical members 5 and the columns D, thereby ensuring strength and preventing buckling. or,
The center portion of the vertical member 5 is pressed toward the column D by the middle cross member 11, so that the vertical member 5 is hard to separate from the column D, and the integral fastening of the two is improved.

FIGS. 3 and 7 show the reinforcing hardware 1 of the wooden building A.
The hole-down hardware 13 is also used, and the hole-down hardware 13 is fixed to the upper and lower ends of the left and right columns D. Accordingly, the column D is reinforced more strongly, and the column D is prevented from being pulled out from the base C or the beam E in the event of an earthquake or the like. Further, in the reinforcing hardware 1 of the wooden building A in FIG. 7, the hole-down hardware 13 is also fixed to the base C and the foundation B or the beam E using the anchor bolt 13 or the penetration bolt 7. Thus, the hole-down hardware 13 is fixed not only in the left-right direction but also in the up-down direction, so that it is more strongly fixed.

<< Others >> First, a supplementary explanation will be given on the prevention of the wooden building A from rising when the reinforcing hardware 1 is used. When an upward pulling force acts on the wooden building A due to an earthquake, a typhoon, or the like, the anchor bolt 2 fixed to the foundation B of the wooden building A causes the cross member 4 under the reinforcing hardware 1 to move to the wooden building A. On the base C and fixed. Therefore, the vertical member 5 of the reinforcing hardware 1 integrated with the horizontal member 4 prevents the pillar D of the wooden building A from being fixed and integrated. At the same time, the horizontal member 4 on the reinforcing hardware A integrated with the vertical member 5 prevents the beam E of the wooden building A that is fixed and integrated from rising. In this way, the pillar D of the wooden building A which is going to float is pressed down by the horizontal member 5 and the upper beam E of the reinforcing hardware A, and
The lifting is prevented. In this way, the wooden building A is prevented from rising.

Second, the fastening of the L-shaped angle hardware 9
Supplementary information such as the easiness of integration is added. Since the L-shaped angle hardware 9 is a single plate having an L-shape, the screw bolt 3 can be formed by forming a bolt hole in advance.
Wooden pillar D on wooden building A side easily and accurately
It can be fixed to the like. On the other hand, since the square metal fitting 10 has a substantially rectangular shape in cross section, it is necessary to drill bolt holes in two opposing places in advance, and use the through bolt 7 or the like to secure the rigidity. Requires work. Furthermore, the L-shaped angle hardware 9 has no risk of internal dew condensation as compared with the rectangular tube hardware 10,
There are advantages such as easy application of the rust preventive agent as a whole, easy handling with no space required until fastening, and the fact that the wall thickness is thicker than that of the rectangular tube hardware 10, so that the strength of the welded portion is strong. The L-shaped angle hardware 9 has such advantages.

Third, in the reinforcing metal member 1 shown in FIGS. 1, 2 and 3, the diagonal member 6 using the L-shaped angle metal member 9 is used.
Has the advantage that the orientation is reversed up and down, and the positional relationship with the middle crosspiece 11 can be easily set. That is, in the reinforcing metal member 1 in the illustrated example, four L
A shaped angle metal part 9 is used, and two pieces are arranged in a straight line vertically so as to form a substantially X-shape. Is set. Accordingly, the end face of the middle crosspiece 11 is easily fitted to the middle crosspiece 11, and welding with the middle crosspiece 11 is easy.
There is an advantage that the transmission of force between the units is smooth, and so on.
The orientation of the oblique member 6 in the illustrated example has such an advantage.

Fourth, the cross member 4 under the reinforcing hardware 1 is
In order to reliably prevent the danger of sinking into the base C,
The size of the lower cross member 4 may be made as large as possible (for example, 50 mm to 40 mm), or a plate may be interposed between the lower cross member 4 and the base C. That is, a downward pressing force may act on the cross member 4 below the reinforcing hardware 1 based on the load on the upper part of the wooden building A, an earthquake, or the like. Therefore, in this case, as a measure to prevent the wooden building A of the reinforcing member 1 from being entangled in the base C, the lower horizontal member 4 may be either a large one or a large one. It is conceivable that a metal plate is interposed between the base and the base C. Of course, it is possible to employ both of them, but in general there is often no need to employ either of them. Prevention of the cross member 4 from getting stuck is as described above.

Fifthly, the position of the anchor bolt 2 for fixing the reinforcing hardware 1 to the base C of the wooden building A is different from the example shown in FIG. 1 and the example shown in FIG. . First, FIG.
In the example of the above, the anchor bolt 2 fastens the lower cross member 4 to the base C and the foundation B of the wooden building A in the vicinity of immediately below the vertical member 5 of the reinforcing hardware 1. Since the vertical member 5 is made of an L-shaped angle hardware, the end of the horizontal member 4 is fixed to the base C or the like using the anchor bolt 2 while using the space area immediately below the lower end surrounded by the lower end thereof. It is possible. Since the anchor bolts 2 are positioned immediately below the vertical members 5 in this manner, when an upward tensile force acts due to an earthquake, a typhoon, or the like, a column that tends to float up against this. There is an advantage that D and the vertical member 5 can be effectively pressed down to contribute to prevention of floating. That is,
Since the anchor bolt 2 fixes the horizontal member 4 to the base C of the wooden building A directly below the vertical member 5, the vertical member 5 integrated with the horizontal member 4 and the vertical member 5 directly above the horizontal member 4 are provided. The pillar D of the wooden building A, which is integrally fastened to the vehicle, functions so as not to float.

On the other hand, in the example of FIG. 1, the anchor bolt 2 fastens the cross member 4 under the reinforcing hardware 1 to the base C or the like of the wooden building A at a position closer to the center than in the example of FIG. ing. In other words, the anchor bolt 2 avoids the lower end of the vertical member 5 and the lower end of the diagonal member 6 and fastens the lower horizontal member 4 to the base C and the foundation B of the wooden building A at the end near the center. are doing. The advantage of the example of FIG. 1 is that the anchor bolt 2 is located at a position avoiding the lower ends of the vertical members 5 and the diagonal members 6, so that the anchor bolt 2 can be easily fixed. The anchor bolt 2 is erected from the base C side of the wooden building A prior to the installation of the reinforcing hardware 1, and a bolt hole previously drilled in the horizontal member 4 below the reinforcing hardware 1 is anchored from above. By externally fitting to the bolt 2, the anchor bolt 2 is easily fixed to the base C of the wooden building A.
On the other hand, performing the fixing work of the anchor bolt 2 near the lower ends of the vertical members 5 and the diagonal members 6 involves some difficulty.
About the fastening position of the anchor bolt 2, the example of FIG.
Is different in this way.

That is, since the reinforcing hardware is made of an integral body having a frame shape, as in the case of the above-described streak of the related art, the mounting technique is used.
There is no difference in the overall strength of the wooden building. And this reinforcement metal, the vertical member functions as a conventional hole-down metal member, reinforces the wooden pillar that is integrally fastened, prevents its buckling, and the horizontal member is integrally fastened. Reinforced wooden beams and foundations to prevent pull-out, and the diagonal members function in a conventional manner to reinforce columns, beams, foundations, and the entire wooden building.
In addition, since the reinforcing hardware is made of a frame-shaped integral body, and is fixed to the pillars, beams, and bases of the wooden building at the top, bottom, left, and right, the reinforcing hardware is used in the event of an earthquake or the like. There is little deformation or looseness, as in the conventional example, such as a streak, a hole-down hardware, and a blade bolt. As a result, during an earthquake or the like, the force flows smoothly without concentrating on the wooden pillars, beams and bases of the wooden building, and even if the diagonal material is damaged, the remaining welding Vertical members,
The danger of collapse of the wooden building is avoided by the cross member and the middle crosspiece, and the wooden building has a stable strength.

The reinforcing metal has an integral frame shape, and the vertical members and the horizontal members are dispersed and fixed to the beams, the base, and the columns on the wooden building side.

Therefore, when this reinforcing metal is used, a crack due to the concentration of the fastening does not occur at the end of the pillar of the wooden building, and a decrease in the strength of the pillar due to the fastening is avoided. The reinforcing hardware is dispersed and fastened to the ends of the pillars in a concentrated, competitive, and identical manner, as in the above-described conventional bracing, hole-down hardware, and blade bolt. It does not occur that they interfere with each other, interfere with each other, and stop properly. Therefore, when this reinforcing metal is used, the horizontal member, vertical member, and diagonal member are accurately fastened and fixed. Therefore, even if a load is applied by an earthquake or the like, the member is hardly damaged or broken. The conventional hole-down hardware function and the diagonal material perform the conventional staggered function.

In this reinforcing metal, vertical members and horizontal members are dispersed and fixed to beams, foundations, columns and the like of a wooden building. Therefore,
In the case where there is a back crack in the pillar, as in the above-described conventional example of this type, the bolts for fixing the hole-down metal fittings are intensively inserted into the back crack, and rattling occurs. It is unlikely that the fastening becomes uncertain and the function of the hole-down hardware is hindered. When this reinforcing metal is used, the influence of the back crack is small due to the dispersion fastening, and the vertical member surely exhibits a hole-down metal function. The reinforcing hardware is made of metal such as steel. Therefore, unlike the above-described conventional wooden struts, there is no adverse effect such as cracking, insect biting, corrosion, use of a desiccant, and types of cedar and cypress. When this reinforcing metal is used, the diagonal material surely exhibits a staggered function.

The reinforcing metal has a tenacity / bending / flexibility /

In addition to adopting a rectangular tube hardware, it is usually desirable that a tensile force or a compressive force is easily applied, and that it is usually desirable to have stickiness, bending, and flexibility.
Shape angle hardware is adopted. Therefore, when this reinforcing metal is used, the reinforcing metal is integrated with the wooden building in a well-balanced manner, and beams, foundations, columns, etc. on the wooden building side, and horizontal members, longitudinal members, diagonal members, etc. on the reinforcing metal member side. Work together easily. Therefore, as in the above-described conventional example of this type, it is avoided that the wooden building is rigidly and rigidly assembled as a whole by the reinforcing structure, and the wooden building is maintained while maintaining appropriate toughness, bending, and flexibility. , Reinforced. Therefore, wooden buildings are damaged,
The risk of breakage and collapse is reduced.

According to the present invention, the metal fittings for reinforcing the wooden building according to the first, second, third, and fifth aspects of the present invention can provide a well-balanced and stable reinforcing structure and increase the overall strength of the wooden building. improves. That is, compared with the above-described conventional example using a streak, a hole-down metal fitting, and a feather plate bolt, a wooden building can withstand the pulling force applied to a column, and has improved seismic resistance, as well as columns and beams. Is prevented from being concentrated on the local area, and buckling of columns and the like is also prevented.

<< Second Effect >> Secondly, this can be realized easily and easily and with excellent workability. That is, the reinforcing hardware of this wooden building has a simple configuration in which it has a frame shape obtained by combining horizontal members, vertical members, and diagonal members, and selectively uses an L-shaped angle hardware and a rectangular tube hardware.
Therefore, installation is easy, and the first point described above is easily realized with excellent workability. Moreover, wooden building beams,
The work is completed by fixing to the base and pillars, and as in the above-mentioned conventional example of this type, there is no time and effort to install the bracing, the hole-down metal fittings, the blade bolts, and the fastening, and from these aspects, In addition, the safety of construction is improved and the construction time is shortened.

[0046] "Other effects" In addition, according to claim 4
In, by adopting the connection reinforcement plate,
Cross-member damage is prevented. That is, when an upward tensile force is applied due to an earthquake or the like, the situation where the lower horizontal member is sunk into the lower end of the upper vertical member or the lower end of the diagonal member is avoided by the interposition of the connection reinforcing plate. In addition, breakage of the cross member is reliably prevented.

According to the sixth aspect of the present invention, the use of the middle cross member prevents the buckling of the diagonal member, and further secures the integration between the vertical member and the column. Is up. In other words, the diagonal members are securely received and held by the vertical members and the columns of the wooden building via the middle crosspieces, and the strength of the diagonally functioning diagonal members is secured, and buckling of the diagonal members is prevented. . At the same time, the central part of the vertical member is pressed toward the column by the middle cross member, so that the vertical member is difficult to separate from the column,
The unity between the two is improved.

According to the seventh aspect, the strength of the pillars and the like is further improved by using the hole-down metal together. In other words, since the hole-down hardware is fixed to the ends of the pillars of the wooden building in addition to the vertical members, the pillars are reinforced more strongly. The strength of pillars and the like of a wooden building is further improved, such as being prevented from being pulled out. According to the eighth aspect, the use of the anchor bolt or the like allows the hole-down metal to be securely fastened.
