Description

  The present invention relates to a plate hardware of a wooden building. That is, the present invention relates to a metal plate used for connecting and fixing a base of a wooden building and foundation concrete.

《Technical background》
In a wooden building, the foundation is connected and fixed on the foundation concrete, and columns and beams are assembled on the foundation.
And the connection fixation to the foundation concrete of the foundation was normally performed generally using the anchor bolt.

《Information on prior art documents》
Examples of such coupling and fixing include those shown in the following Patent Document 1.
Japanese Patent No. 3597788

<Conventional technology>
By the way, irrespective of such a general example, an example of a more reliable and firm connection and fixation that is superior in strength has been proposed and put into practical use.
In other words, it has been developed that the upper plate hardware is fixed to the base side, the lower plate hardware is fixed to the foundation concrete side, and the upper plate hardware and the lower plate hardware are connected and fixed with bolts. .
In this type of conventional example, one upper plate hardware, one large lower plate hardware, one connecting bolt, and the like are used as one set. The foundation was connected and fixed on the foundation concrete by arranging many in between.

By the way, the following problems have been pointed out in the conventional example using such an upper plate hardware, lower plate hardware, connection bolts and the like.
<First problem>
First, a problem in strength has been pointed out regarding the fixing of the lower plate hardware to the foundation concrete.
FIGS. 7 (3) and 7 (4) are front explanatory views in which the main part of the lower plate hardware is enlarged for explanation of this type of conventional example, and (3) FIG. 4) The figure shows the case where an upward tensile force is applied. As shown in the figure, the lower plate hardware 1 can be fixed to the basic concrete A by using a plurality of horizontal pins (anchor pins) 2 through the large-diameter holes 3 of the lower plate hardware 1. It was done by inserting into the small diameter hole H of the foundation concrete A to be done.
In the figure, reference numeral 5 denotes a connecting bolt 5 for connecting and fixing the upper plate hardware (not shown) on the base side, and the head of this connecting bolt 5 is welded to the upper plate hardware. At the same time, the lower part was screwed to the nut 6 welded to the lower plate hardware 1.

Now, in the basic concrete A, reinforcing bars, stones, and the like are present and mixed, and it is not easy to drill small-diameter holes H at respective predetermined positions. Accordingly, it is extremely difficult to match the center of each small diameter hole H on the side of the foundation concrete A with the corresponding large diameter hole 3 on the lower plate hardware 1 side. Even portions where 3 and 3 do not correspond at all occur.
Therefore, the lower plate hardware 1 is fixed to the basic concrete A by inserting the head of the horizontal pin 2 into the large-diameter hole 3 corresponding to the small-diameter hole H and inserting the tip of the horizontal pin 2 into the small-diameter hole. It was done by densely attaching to H. Therefore, when an upward tensile force is applied to the lower plate metal 1 via the connecting bolt 5 from the state shown in FIG. 7A, the state shown in FIG. 7B is obtained. (In the figure, the horizontal pin 2 shows a cross-sectional view of only the tip portion excluding the head), and a problem in strength has been pointed out.
That is, in this case, the lower plate metal 1 and the large-diameter hole 3 are displaced upward, while the lateral pin 2 and the small-diameter hole H hold the positions so far. 7 (1), the horizontal pin 2 where the center of the large-diameter hole 3 and the small-diameter hole H coincided with each other is in contact with the lower edge of the large-diameter hole 3 and becomes a contact / fulcrum. Apply reaction force and resistance force corresponding to the tensile force. On the other hand, the lateral pin 2 at the center mismatching location does not abut against the lower edge of the large-diameter hole 3, so that no reaction force or resistance force acts on the tensile force.
Therefore, in this type of conventional example, there is a risk that the fixing of the lower plate hardware 1 to the foundation concrete A by the lateral pins 2 may be uncertain without being maintained, and the lower plate hardware 1 moves upward by a tensile force. There was a risk of being pulled out, and problems with strength were pointed out.

<< Second problem >>
Secondly, the lower plate hardware 1 is often not in close contact with the foundation concrete A, and a problem in strength has been pointed out also from this aspect.
That is, the surface of the foundation concrete A is not flush, but is often curved or uneven, so that the large lower plate hardware 1 is not in close contact with each other, and a gap is randomly generated between the two. There are many things.
Therefore, in this type of conventional example, when a tensile force or a compressive force is applied upward, the fastening force between the horizontal pins 2 serving as a fulcrum for the reaction force and the resistance force becomes uneven, and the horizontal pin 2 From these aspects, the lower plate hardware 1 is uncertainly fixed to the basic concrete A, and a problem in strength has been pointed out.

《Third problem》
Thirdly, there is often a step between the foundation side and the foundation concrete A side, and it has been pointed out that the connection fixing by the connecting bolt 5 becomes difficult at such a step portion.
In particular, there are many cases where the outer wall material of the foundation is located in the front and the foundation concrete A is located in the rear. At such a stepped portion, the upper plate hardware fixed to the outer wall material of the foundation and the foundation It is not easy to connect and fix the lower plate hardware 1 fixed to the concrete A with the straight connection bolts 5.
Accordingly, in this type of conventional example, there are cases where the connection between the upper and lower portions by the connection bolt 5 becomes uncertain or impossible, and a problem in strength has been pointed out also from this aspect.

《Fourth problem》
Fourth, the upward tensile force and downward compressive force do not always act along the vertical line, but often incline and act obliquely, but the force transmission in such a case is smooth. There was also a problem in strength from this aspect.
That is, in many cases, the tensile force and compressive force due to an earthquake or a typhoon act diagonally, but in this type of conventional example, the upper plate hardware and the lower plate hardware 1 are connected vertically by the connecting bolt 5 along the vertical line. Since it was fixed, there was a problem in terms of strength, such as a mismatch in the transmission of force between the upper and lower sides, resulting in a deviation and unnecessary dispersion of force.

《Fifth problem》
Fifth, the problem of poor usability has been pointed out, such as the position of the lower plate hardware 1 being restricted by the connecting bolt 5.
That is, in this type of conventional example, the connecting bolt 5 has its head welded to the upper plate hardware and the lower portion screwed to the nut 6 of the lower plate hardware 1. Therefore, the range of use of the lower plate hardware 1 is limited by the length dimension of the connecting bolt 5, and it is easy to position and arrange the lower plate hardware 1 at an appropriate vertical height position according to the situation. However, it is necessary to prepare the connecting bolts 5 of various lengths in advance, which is not easy to use, and problems have been pointed out in work efficiency.

《Sixth problem》
Sixth, it was pointed out that in a wooden building where a compressive force acts in the event of an earthquake or typhoon, the pillar may sink into the base B, leading to the building falling over. That is, bracing is used to prevent such danger, but in this type of conventional example, there is still a concern about insufficient strength of the base B.

<< Seventh Problem >>
Seventhly, in the case of wooden buildings where tensile forces act in the same way during earthquakes and typhoons, it has been pointed out that the first-floor pillars and the second-floor pillars may rise, leading to the building falling over.

《Eighth problem》
Eighth, the force concentrates on the lower corner of the wooden building, and in particular, the force concentrates on the diagonal direction due to the bracing.
On the other hand, in this type of conventional example, one set of upper plate hardware, connecting bolt 5 and lower plate hardware 1 is used for one orthogonal surface at the lower corner, and one set is similarly applied to the other orthogonal surface at the lower corner. The upper plate hardware, connecting bolt 5, and lower plate hardware 1 were used. In other words, both sets were used independently for two orthogonal surfaces.
Therefore, when a tensile force or compressive force is applied to one surface (or other surface) at the lower corner of the corner, reaction force or resistance force is applied to this one surface (or other surface). Only the upper plate hardware, the connecting bolt 5 and the lower plate hardware 1 of the set were pointed out, and the lack of strength at the corner was pointed out. The reaction force and resistance force to the tensile force and compressive force were not sufficient, and dangers such as pulling out, crushing and falling were pointed out.

<< About the present invention >>
In view of such a situation, the metal plate of the wooden building of the present invention has been made to solve the problems of the conventional example.
And the present invention firstly secures the lower plate hardware, secondly can cope with the curvature and unevenness of the foundation concrete surface, and thirdly it can cope with the step between the foundation and the foundation concrete. Fourth, it can also handle oblique tensile and compressive forces. Fifth, it is easy to use because it employs a connecting vertical screw. Sixth, it is possible to prevent the pillar from being embedded in the base. 7 is intended to propose a metal plate for a wooden building, which prevents the lifting of the pillar, and eighthly, the strength at the corner of the building is excellent.

<About the action>
Since the present invention comprises such means, the following is achieved.
In this wooden building, the upper plate hardware fixed on the foundation side is screwed and connected to the lower plate hardware fixed on the foundation concrete side with connecting vertical screws, so that the foundation is on the foundation concrete. Are connected and fixed.
The upper plate hardware is composed of a horizontal plate main body portion fixed to the base side and a vertical plate portion fixed to the pillar, but a horizontally long horizontal plate main body portion and a vertical plate portion are also conceivable. For building corners, it is also conceivable to integrally form upper and lower plate hardware in two directions at a right angle.

(1) First, the lower plate hardware is divided into a plurality of pieces. Therefore, even if there is a location where the center does not coincide between the large-diameter hole of the lower plate hardware and the small-diameter hole of the foundation concrete, the effect is reduced.
That is, when a tensile force acts on the lower plate hardware, the horizontal pin where the center of the large-diameter hole and the small-diameter hole coincides contacts the lower edge of the large-diameter hole and functions as a fulcrum for the reaction force To do. Therefore, the fastening of the lower plate hardware to the foundation concrete is secured and maintained by the resultant force of the reaction force in each lower plate hardware.
(2) Secondly, the surface of the foundation concrete is often curved or uneven, but this lower plate hardware is divided into a plurality of pieces, so it can cope with curvature and unevenness. , It can be fixed to the foundation concrete with each horizontal pin for each lower plate hardware. Therefore, it is ensured that the lower plate hardware is fixed to the foundation concrete.
(3) Thirdly, there is often a step between the foundation and the foundation concrete, but the connecting vertical screw that connects and fixes the two is screwed using a U-ring with a nut. Therefore, it is possible to cope with steps.
In other words, the connecting vertical screw loosely inserted in the U-ring is adjusted to the front / rear position corresponding to the step and moved back and forth, and then screwed with the nut to ensure secure connection and fixing even if there is a step. Is done.
(4) Fourth, when the tensile force or compressive force acts at an angle, the connecting vertical screw is screwed using a U-ring with a nut, so it can handle an inclined force. is there.
That is, when the force acts with an inclination, the connecting vertical screw is driven to change its direction in the loosely inserted U-ring and is inclined along the direction of the force.

(5) Fifth, the vertical dimensions of the foundation and the foundation concrete are various, and the appropriate dimensions and positions of the upper plate hardware and the lower plate hardware to be fixed are also various.
Therefore, the connecting vertical screw that connects and fixes these is screwed up and down with a nut or U-ring with nut, and can be adapted to the various dimensions and positions described above by freely changing the screwing location. It is.
(6) Sixth, a pillar is placed on the base, and the strength of the base may be insufficient, but the horizontal dimension of the horizontal plate main body of the upper plate hardware is lengthened and stretched and secured. By placing it, the foundation is reinforced and the penetration of the pillar into the foundation is also prevented.
(7) Seventh, the vertical dimension of the vertical plate portion of the upper plate hardware is lengthened and stretched and fixed to the column, and the upper end is fixed to the column or beam on the second floor, so that the column is Reinforced. The column is firmly fixed to the base with such a vertical plate portion and an upper plate hardware, and its lifting is prevented.
(8) Eighth, tensile forces and compressive forces are concentrated on the lower corners of the building, and incline and oblique forces are particularly strongly exerted by the braces fixed at the corners.
Therefore, regarding the two sets of upper plate hardware and lower plate hardware facing each other at a right angle to the corner, the corner strength of the building is improved if they are connected and integrated. That is, the acting tensile force and compressive force are divided into two directions, and the reaction force acts on the two directions in the two directions, so that the corner strength is enhanced.
(9) Now, the wooden hardware of this wooden building exhibits the following effects.

<< First effect >>
First, the lower plate hardware is secured. That is, in the plate hardware of the wooden building of the present invention, the lower plate hardware on the foundation concrete side is divided into a plurality of pieces.
Therefore, even if there is a portion where the centers do not coincide between the large diameter hole of the lower plate hardware and the small diameter hole of the foundation concrete, the influence is reduced. When a tensile force is applied, necessary and sufficient reaction force and resistance force are secured by the resultant force of the horizontal pins at the locations where the centers coincide with each other for each lower plate hardware.
As in the case of this type of conventional example, since a large piece of lower plate hardware is used, it is uncertain that it is not secured to the foundation concrete, and the lower plate hardware is pulled out by the tensile force of an earthquake or typhoon. The risk of falling and the risk of the building floating is resolved, and the strength is improved.

<< Second effect >>
Secondly, it can sufficiently cope with the curvature and unevenness of the foundation concrete. That is, in the plate hardware of the wooden building of the present invention, the lower plate hardware is divided and used in this way.
Therefore, the lower plate hardware can cope with the curvature and unevenness of the surface of the basic concrete, and compared with this type of conventional example in which a single large lower plate hardware was used, there is more clearance than the basic concrete. It is firmly attached.
Therefore, when a tensile force or compressive force is applied due to an earthquake or typhoon, the lateral pin is difficult to loosen and functions as a fulcrum for reaction force and resistance force. From this aspect, the lower plate hardware is fixed to the foundation concrete. The strength is improved, for example, by ensuring the removal and preventing the pulling out.

《Third effect》
Thirdly, it can sufficiently cope with the level difference between the foundation and the foundation concrete. That is, in the metal plate of the wooden building of the present invention, the connecting vertical screw is screwed through the U-ring.
Therefore, even if there is a step between the foundation and the foundation concrete, it is possible to connect and fix with the connecting vertical screw corresponding to the step, and as in the conventional example of this kind, the connection and fixing between the upper plate and the lower plate are possible. However, there will be no uncertain or impossible parts, and the strength will be improved, for example, a well-balanced stable structure can be obtained, such as smooth transmission of force during an earthquake or typhoon.

<< 4th effect >>
Fourth, it can sufficiently cope with an oblique tensile force and compressive force. That is, in the metal plate of the wooden building of the present invention, the connecting vertical screw is screwed through the U-ring in this way.
Therefore, when a tensile force or a compressive force due to an earthquake or a typhoon acts with an inclination, the connecting vertical screw along the vertical line is inclined in accordance with the direction of the force to change its direction. Therefore, as in the case of this type of conventional example described above, the force transmission is smoothed without deviation compared to the case where it is firmly fixed with a perpendicular line, and a stable proof stress is obtained from this surface, and the strength is improved. To do.

《Fifth effect》
Fifth, the use of a connecting vertical screw improves usability. That is, in the metal plate of the wooden building of the present invention, the upper part of the connecting vertical screw is screwed to the nut of the upper plate metal or a U-ring with a nut, and the lower part is screwed to the U-ring of the lower metal plate with a nut. Has been.
Therefore, the connecting vertical screw can be of any length, and can be cut and used as appropriate by simply preparing a fixed length screw. The vertical height of the lower plate hardware The position and range of use are not limited or limited. Therefore, it is easy to use and the working efficiency is improved as compared with the above-described conventional example.

<< Sixth Effect >>
Sixth, penetration of the pillar into the base is prevented. That is, in the metal plate of the wooden building of the present invention, when the horizontal plate body of the lower metal plate is extremely long, the following is obtained.
That is, the strength of the foundation is reinforced by such a horizontal plate body, and even if a compressive force acts on the foundation via the pillar in the event of an earthquake or typhoon, the pillar is The danger of falling into the building is prevented and the lack of foundation strength is resolved.

<< Seventh effect >>
Seventh, the lifting of the pillar is also prevented. That is, in the metal plate of the wooden building of the present invention, when the vertical plate portion of the upper metal plate is extremely long and is fixed to the pillar or beam on the second floor, the following occurs.
That is, even if a tensile force acts upon an earthquake or typhoon, the first and second floor pillars are reinforced by such vertical plate portions and fixed immovably. There is no risk of the column rising and falling down.

《Eighth effect》
Eighth, it is excellent in building corner strength. That is, in the metal plate of the wooden building of the present invention, when a structure in which the two-way surfaces are connected integrally at right angles with respect to the upper plate metal and the lower plate metal for the corner, the following is adopted.
That is, the strength of the lower part of the building corner where the tensile force and the compressive force are concentrated and acts in the event of an earthquake or typhoon, such as an oblique force acting due to the bracing, becomes excellent. That is, the force is distributed in two directions, and the reaction force acts on each surface. Therefore, the corner strength is doubled as compared with the conventional example of this type that relies on the reaction force of only one surface. As a result, the dangers of pulling out, crushing, falling over, etc. are reliably eliminated.
As described above, the effects exerted by the present invention are remarkably large, such as all the problems existing in this type of conventional example are solved.

About wooden buildings
First, a wooden building in which the upper and lower plate hardware 7 and 8 are used will be outlined with reference to FIG.
In a wooden building, which is a wooden framed building, a wooden base B is connected and fixed on a foundation concrete A made of concrete raised around the ground. The wooden pillars C are vertically mounted on the horizontal base B, and the wooden beams D are horizontally mounted on the pillars C.
In the case of the two-story building and the three-story building, the column C and the beam D are further placed and assembled on the beam D sequentially. Regardless of the illustrated example, a common pillar common to the first and second floors is used as the pillar C, and the beam D may be attached to the pillar C.
The base B and the pillar C have a size of, for example, about 105 mm × 105 mm, and a generally planar outer wall material E is attached to the outer surface thereof (see also FIG. 2 and subsequent figures). In addition, in the vertical rectangular area formed by the upper and lower beams D and the base B and the left and right pillars C, crossing in the X shape between the upper and lower corners, the bracing (difference) F is for reinforcement. Installed on.
The wooden building is roughly like this.

<< About the connection and fixing structure of foundation B >>
Now, in this way, in the wooden building, the base B is connected and fixed on the foundation concrete A. And in this invention, this connection fixation is implemented using the upper plate metal object 7, the lower plate metal object 8, and the connection vertical screw 9, as shown in FIG.
That is, the base B and the foundation concrete A are connected and fixed by the connection vertical screw 9 between the upper plate metal 7 fixed to the base B side and the lower plate metal 8 fixed to the foundation concrete A side. ing.
And such an upper plate metal object 7, lower plate metal object 8, and connecting vertical screw 9 are used as one set, and each such set is arranged between the base B and the foundation concrete A. Thus, the base B is connected and fixed to the foundation concrete A.
These will be described in detail below.

<About the lower plate hardware 8>
First, the lower plate hardware 8 will be described with reference to FIGS. 1, 2, 3, and 6 (2), FIG. 7 (1), (2), and the like.
The lower plate hardware 8 is provided with a plurality of large diameter holes 10, and the foundation concrete A is provided with a plurality of corresponding small diameter holes G. The horizontal pin 11 is loosely inserted into each large-diameter hole 10 and closely inserted into the small-diameter hole G, whereby the lower plate hardware 8 is fixed to the foundation concrete A.
A U-ring 12 is welded to the lower plate metal 8, and the lower part of the connecting vertical screw 9 is loosely inserted into the U-ring 12 and screwed with a nut 13. Such lower plate hardware 8 is used by being divided into a plurality of sheets for each set.

Such lower plate hardware 8 will be further described in detail. First, in the example shown in FIG. 1 (1), (3), FIG. 2, FIG. 4, FIG. 7 (1), (2), etc., the lower plate hardware 8 is set for each set. The upper and lower parts are divided into two pieces, and one common connecting vertical screw 9 is used.
Further, in the example shown in FIG. 1 (2), the lower plate hardware 8 is divided into upper and lower three pieces for each set, and one common connecting vertical screw 9 is used. ing. In the example shown in FIG. 3, each set is divided into two pieces on the right and left sides, and two connecting vertical screws 9 are used, one for each.
Of course, in addition to the illustrated example, the lower plate hardware 8 can be divided into a plurality of pieces in the vertical and horizontal directions. For example, an example in which the lower plate hardware 8 is divided into a total of 4 pieces each of the vertical and horizontal two pieces is also possible. . Further, the number of connecting vertical screws 9 used can be various in addition to the illustrated example in which each one is used in principle. For example, as shown in FIG. Examples are also possible.

As shown in FIG. 6 (2), FIG. 7 (1), (2), and others, the lower plate hardware 8 is provided with a plurality of large-diameter holes 10 in advance. In the illustrated example, four rows are arranged horizontally.
Correspondingly, the foundation concrete A is provided with a plurality of small-diameter holes G in advance, and in the illustrated example, four small holes G are provided side by side. The small diameter hole G has a smaller diameter than the large diameter hole 10 and substantially the same diameter as the lateral pin 11. And the lateral pin 11 is loosely inserted into a part of the large-diameter hole 10 of the lower plate hardware 8 except for the head portion while leaving a margin in area, and a small-diameter hole of the same diameter of the foundation concrete A. G is densely inserted into G.
At that time, it is ideal that each large-diameter hole 10 and the small-diameter hole G or the lateral pin 11 are positioned so as to correspond to each other coaxially with the same center. Further, in the examples of FIGS. 6 (2), 7 (1), 7 (2), the horizontal pins 11 are inserted using all the large-diameter holes 10, but this is not always necessary. Rather, as in the examples shown in FIGS. 2, 3, 4, and 5, at least one large-diameter hole 10 on each of the left and right of the connecting vertical screw 9 is used to insert the horizontal pin 11. It only has to be done.
In addition, you may use a bolt as this horizontal pin 11, Furthermore, the volt | bolt which is an example of this horizontal pin 11 penetrates the small diameter hole G of foundation concrete A, and has the front-end | tip part made into foundation concrete A. It may be projected and exposed on the back side (the surface opposite to the lower plate hardware 8), and may be screwed with a nut.

And as shown in each figure, the U ring 12 is weld-joined to the center part of the outer surface side of the lower plate metal object 8. The U-ring 12 has a vertical dimension equal to or less than the vertical dimension of the lower plate hardware 8, but has a vertical dimension of at least about 1/5 of the vertical dimension. Further, the substantially U-shaped vertical hole of the U-ring 12 is much larger in diameter than the connecting vertical screw 9.
The lower part of the connecting vertical screw 9 is loosely inserted vertically in a part of the space of the vertical hole of the U-ring 12 with a margin in area. At the same time, the lower part of the loosely connected connecting vertical screw 9 is screwed to the U-ring 12 by the portion exposed below the U-ring 12 being screwed with the nut 13.
The lower plate hardware 8 is like this.

<< Upper Plate Hardware 7 >>
Next, the upper plate hardware 7 will be described with reference to FIGS. 1 to 6 (1). In the example shown in FIG. 1, FIG. 2, FIG. 3, FIG. 4 and FIG. 6 (1), the upper plate metal 7 is fixed to the base B side by a plurality of horizontal screws 14 and nuts. 15 is welded, and the upper part of the connecting vertical screw 9 is screwed to the nut 15. On the other hand, the upper plate metal 7 in the example shown in FIG. While being fixed to the B side, the U ring 16 is welded, and the upper part of the connecting vertical screw 9 is loosely inserted into the U ring 16 and screwed with a nut 17.
In both cases, the upper plate hardware 7 includes a horizontal plate main body portion 18 fixed to the base B via the outer wall material E and a vertical plate portion 19 fixed to the column C via the outer wall material E. It consists of a formed structure.

The upper plate hardware 7 will be described in further detail. First, unlike the above-described lower plate hardware 8, one upper plate metal 7 is used for each set (in the example of the corner of FIG. 4, two sets are integrated into one).
Then, the horizontal plate main body 18 of the upper plate metal 7 is fixed to the base B through the outer wall material E by a plurality of horizontal screws 14 as shown in FIG. 6 (1). Has been. The vertical plate portion 19 of the upper plate metal 7 is screwed and fixed to the column C via the outer wall material E with a plurality of horizontal screws 14.
Further, when the column C is positioned at the end of each surface of the building (for example, see the left side of FIG. 1 (1) and FIG. 2), the vertical plate portion 19 stands from the end of the horizontal plate main body portion 18. If the column C is located at the center of the building other than the end of each face (see, for example, the right side of FIG. 1 (2) and the right side of FIG. 2), It is erected from the center. In the former case, the upper plate hardware 7 has a substantially L shape as a whole, and in the latter case, it has a substantially inverted T shape.

In the example shown in FIGS. 1, 2, 3, 4, and 6 (1), a nut made of a long nut is provided on the outer surface side of the horizontal plate body 18 of the upper plate metal 7. 15 is welded.

The metal plate 7 and the lower metal plate 8 are connected and fixed.
On the other hand, in the example shown in FIG. 5, the U-ring 16 is welded to the outer surface side of the horizontal plate body 18 of the upper plate metal 7. The U-ring 16 has a configuration according to the U-ring 12 described above. That is, the U-ring 16 has a vertical dimension equal to or smaller than the vertical dimension of the upper plate metal 7, but has a vertical dimension of at least about 1/5 of the vertical dimension. The substantially U-shaped vertical hole of the U-ring 16 has a connecting vertical screw. The diameter is larger than 9, that is, it is longer in the front and rear in a flat section.
Then, the upper part of the connecting vertical screw 9 is loosely inserted vertically in a part of the space of the vertical hole of the U-ring 16 with a margin in area. The upper part of the connecting vertical screw 9 which is loosely inserted together with this, the portion exposed on the U-ring 16 is screwed with a nut 17 and is thus screwed to the U-ring 16.
Accordingly, the connecting vertical screw 9 is fixedly fixedly connected between the upper plate metal 7 and the lower plate metal 8 by screwing the upper part with the nut 17 and screwing the lower part with the nut 13 described above. Yes.

By the way, the upper plate hardware 7 of the example of FIG. 3 is as follows. That is, the horizontal plate main body portion 18 of the upper plate hardware 7 of this example has a horizontally long dimension, is extended along the base B, and the edges of the upper plate hardware 7 adjacent to each other are slightly spaced apart from each other. It is approaching in a non-overlapping position relationship. In other words, the horizontal plate main body 18 has an extremely long dimension and is adjacent to the left and right sets as long as they are not in contact with each other.
Further, the upper plate metal 7 of the example shown in FIG. 1 (3) is as follows. That is, the vertical plate portion 19 of the upper plate metal 7 in this example has a vertically long dimension, extends along the column C, and is fixed to the column C and the beam D on the second floor. That is, the vertical plate portion 19 is set to be extremely vertically long, and the upper end thereof is fixed below the pillar C on the second floor.

<< About the upper plate hardware 7 and the lower plate hardware 8 for the corner >>
Next, examples of FIGS. 4 and 5 will be described. In the example shown in FIG. 4, the upper metal plate 7 for the building corner has a structure in which the two-sided one is connected integrally at a right angle. That is, the upper plate hardware 7 in this example is a set of both sets for two-direction surfaces sandwiching the corners of the building, and the horizontal plate body 18 and the vertical plate 19 are integrally formed at a right angle and manufactured. in use.
On the other hand, in the example shown in FIG. 5, the lower metal plate 8 for the building corner has a structure in which the ones for the two-direction surfaces are integrally connected by connecting at right angles. In other words, the lower plate hardware 8 in this example is one in which the upper divided parts are integrally formed at right angles from both sets for two-direction surfaces sandwiching the corner of the building.
It should be noted that, regardless of the illustrated example, the divided lower lower plate hardware 8 may be integrally formed, and the upper and lower lower plate hardware 8 may be integrally formed. .
The upper plate hardware 7 and the lower plate hardware 8 for the corner are as described above.

《Action etc.》
The upper and lower plate hardware 7 and 8 of the wooden building of the present invention is configured as described above. Therefore, it becomes as follows.
In this wooden building, the upper plate hardware 7 on the base B side is connected and fixed to the lower plate hardware 8 divided into a plurality of pieces on the basic concrete A side by connecting vertical screws 9, so that the base B is mounted on the basic concrete A. (See FIGS. 1, 2, 3, etc.).
The upper plate metal 7 is fixed to the base B side with a horizontal screw 14 (see FIG. 6 (1), etc.), and the lower plate metal 8 is connected with a large diameter hole 10 and a small diameter hole G with a horizontal pin 11. It is fixed to the foundation concrete A (see FIG. 6 (2) and the like). The upper part of the connecting vertical screw 9 is screwed to the upper plate metal 7 with a nut 15 or a U-ring 16 with a nut 17 (see FIG. 6A), and the lower part is a U with a nut 13. The ring 12 is screwed to the lower plate hardware 8 (see FIG. 6B).
The upper plate hardware 7 includes a horizontal plate main body portion 18 fixed to the base B side and a vertical plate portion 19 fixed to the column C (see FIGS. 2 and 3). A horizontally long horizontal plate body 18 (see FIG. 3 and the like) and a vertically long vertical plate 19 are also conceivable (see FIG. 1 (3)).
Furthermore, as an example for a corner of a building, an example in which the upper plate metal 7 in two directions is integrally formed at a right angle (see FIG. 4) or an example in which a lower plate metal 8 in a two directions is integrally formed at a right angle is also available. (See FIG. 5).
Then, when such an upper plate hardware 7 and lower plate hardware 8 are used, the following (1) to (8) are obtained.

(1) First, reinforcing bars, stones, etc. are present and mixed in the foundation concrete A, and each of the foundation concrete A that has been previously drilled and prepared in each predetermined position, that is, in the lower plate hardware 8. It is not easy to precisely drill the small-diameter holes G at positions that should correspond to the radial holes 10, respectively.
Therefore, when the lower plate hardware 8 is fixed to the foundation concrete A side, each large-diameter hole 10 on the lower plate hardware 8 side and each small-diameter hole G on the foundation concrete A side are accurately matched by matching the centers. It is extremely difficult to position.
Therefore, as a countermeasure, the lower plate hardware 8 is divided into a plurality of pieces, and the plurality of lower plate hardwares 8 correspond to this. That is, since there are a plurality of lower plate hardware 8 even if the center of the large diameter hole 10 on the lower plate hardware 8 side and the small diameter hole G on the foundation concrete A side are not coincident with each other. The effect is reduced.
This point will be further described in detail. When an upward tensile force is applied to the lower plate hardware 8 via the connecting vertical screw 9 from the state of attachment shown in FIG. 7 (1), the state shown in FIG. 7 (2) Thus, the reaction force and resistance force against the tensile force are secured.
As shown in the figure, each lower plate metal piece 8 and the large diameter hole 10 are displaced upward by the tensile force, but the horizontal pin 11 and the small diameter hole G hold the position so far (in the drawing, The horizontal pin 11 is a cross-sectional display of only the tip portion excluding the head portion). For each lower plate hardware 8, the horizontal pins 11 where the centers of the large-diameter hole 10 and the small-diameter hole G are in contact with the lower edge of the large-diameter hole 10, respectively. Function as.
With the horizontal pin 11 having the center aligned in this way as a fulcrum, a reaction force having the same tensile force and the same direction and acting in the opposite direction acts, and the resultant force of each reaction force in each lower plate hardware 8 is necessary and sufficient. Resistance will be ensured. Accordingly, the strength of the lower plate hardware 8 can be secured and maintained, and sufficient strength can be obtained.

(2) Secondly, the surface of the foundation concrete A is often curved or uneven, and is often not flush.
On the other hand, since the lower plate hardware 8 is divided into a plurality of pieces and used, it is possible to finely cope with such curves and irregularities, and adheres to the foundation concrete A without any gaps. It is possible.
That is, each of the horizontal pins 11 is individually and closely connected to the foundation concrete A, and each of the lateral pins 11 is provided with the large-diameter hole 10 so that each of the foundation pins can be uniformly, reliably, and not deficient. It comes to be tightly inserted into the small-diameter hole G of A, and is less likely to loosen and functions reliably as a fulcrum of reaction force and resistance force. Therefore, also from this surface, the lower plate hardware 8 is securely fixed to the basic concrete A, and the strength is improved.

(3) Third, there is often a step between the outer wall material E on the outer surface of the upper base B and the lower foundation concrete A. In particular, the outer wall material E is often located at the front and the foundation concrete A is often located at the rear.
Therefore, the connecting vertical screw 9 for connecting and fixing the upper plate metal 7 on the base B side and the lower plate metal 8 on the foundation concrete A side is provided with a U ring 12 with a nut 13 or a U ring 12 with a nut 17. The ring 16 is screwed and can sufficiently cope with such a step.
That is, the connecting vertical screw 9 loosely inserted into the U-rings 12 and 16 of the lower plate hardware 8 and the upper plate hardware 7 is adjusted to the front and rear positions corresponding to the steps and moved back and forth to properly position the nut. By connecting with screws 13 and 17, reliable connection and fixation are realized. Even when the U-ring 16 with a nut 17 is used only on the upper plate metal part 7 side, or when the U-ring 12 with a nut 13 is used only on the lower plate metal part 8 side, it is possible to realize sufficiently secure connection and fixation. is there.
In this way, the upper and lower plate hardwares 8 and 8 and the foundation B and the foundation concrete A are securely connected and fixed, even though there are front and rear steps, using the vertical connecting vertical screws 9. Will come to be. There are no places where connection and fixing are impossible or uncertainties, and the strength is improved accordingly.

(4) Fourth, the upward tensile force and the downward compressive force do not always act along the vertical line, and often act obliquely and obliquely.
On the other hand, a connecting vertical screw 9 for connecting and fixing the upper plate metal 7 and the lower plate metal 8 is screwed using a U ring 12 with a nut 13 or a U ring 16 with a nut 17. It is possible to cope with such an obliquely acting force.
That is, when the tensile force or the compressive force acts at an inclination, the connecting vertical screw 9 follows the direction of the force in the vertical hole of the U-ring 12 or the vertical hole of the U-ring 16 that has been loosely inserted. And it easily turns and tilts along the direction of the force. Accordingly, the transmission of force is smoothed as expected, and the dispersion of useless force is prevented, so that the strength is improved accordingly.

(5) Fifth, the vertical dimension of the foundation B and the foundation concrete A varies depending on the building. Therefore, the upper plate hardware 7 and the lower plate hardware 8 fixed to the foundation B and the foundation concrete A Appropriate vertical dimensions and vertical positions vary.
Therefore, the connecting vertical screw 9 for connecting and fixing the upper plate metal 7 and the lower plate metal 8 is screwed up and down by a nut 15, a U ring 16 with a nut 17, and a U ring 12 with a nut 13. In addition, by freely changing the point of screwing, it is possible to easily cope with the various vertical dimensions and vertical positions described above. What is necessary is just to cut and remove the excess dimension.
As described above, since the connecting vertical screw 9 is used for fixing the upper and lower connections, it is highly versatile and has excellent usability such as being able to meet various dimensions and position needs.

(6) Sixth, in a wooden building, a wooden pillar C is vertically placed on a wooden base B, and the strength of the base B is often insufficient.
Therefore, in such a case, the horizontal dimension of the horizontal plate body portion 18 of the upper plate metal 7 is made long, and the ends between the adjacent upper plate metal 7 are stretched and fixed to the extent that they are adjacent to each other. The base B is reinforced. Thus, for example, when a compressive force is applied to the base B via the pillar C, the penetration of the pillar C into the base B is prevented.

(7) Seventhly, in a wooden building, a case in which the column C is lifted from the base B when a tensile force is applied has been reported.
Therefore, when there is such a possibility, the vertical dimension of the vertical plate portion 19 of the upper plate metal piece 7 is made long, extended and fixed along the column C, and the upper end is connected to the column C or beam D on the second floor. The pillar C is reinforced by being fixed.
Thus, the column C is firmly fixed to the base B and the foundation concrete A by way of the upper plate metal 7 and the vertical plate portion 19, and for example, when a tensile force is applied, the lifting of the column C is prevented. Is done.

(8) Eighth, tensile forces and compressive forces are concentrated on the lower corners of wooden buildings, and the slanted diagonal tensile and compressive forces are generated especially by the bracing F fixed to the corners. Acts powerfully.
Therefore, two sets of upper plate hardware 7 or two sets of lower plate hardware 8 for two-direction surfaces positioned at right angles at the corners are integrally formed by connecting the two sets to each other at right angles. This will improve the strength at the corner of the building.
That is, the force acting on one direction surface (or another one-direction surface) of the corner is decomposed into the upper plate metal 7 side connected to the one-direction surface side and the upper plate metal material 7 side connected to the other direction surface. The Or it is decomposed | disassembled into the lower plate metal object 8 of the one direction surface side connected, and the lower plate metal object 8 of the other direction surface side.
And reaction force and resistance force come to act on both sides of the two directions, respectively, with respect to the component force divided into two in this way. That is, it is possible to respond to one force with two resultant forces and reaction forces.
In this way, the acting tensile force and compressive force are distributed and divided in half toward the two-direction surfaces, and the reaction force acts on each surface against this half-forced component. Strength will double. That is, the strength at the corner is greatly improved by dividing the force into two and dealing and sharing with two reaction forces.
