DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fastening structure for firmly fixing a foundation, a base and a pillar in a wooden framed house or a wooden wall structure house, and a building hardware used in this structure.

[0002]

2. Description of the Related Art In Japan, where there are many earthquakes, in a wooden framed house or a house with a wooden wall structure (so-called 2 × 4 construction method), upper structural materials such as wall panels and columns are firmly attached to a foundation so that they can be moved up and down during an earthquake. It is important to have a structure that can withstand the pull-out force due to vibration in order to avoid major damage.
For example, in a house by the 2 × 4 construction method, as shown in FIG. 5, a base 2 is placed and fixed on a cloth foundation 1, and a joist 3 is erected thereon and a floor panel 4 is stretched. The lower part of the anchor bolt 5 is fixed to the cloth foundation 1 in advance, and the upper part is projected from the top end of the cloth foundation 1. Then, the upper part of the anchor bolt 5 is inserted into a through hole provided through the base 2 and the joist 3 placed on the base 2, and the nut 2 screwed from the upper surface of the joist 3 to the cloth base 1 to the base 2. And the joist 3 are fixed.
Next, a floor panel 4 is put on the joist 3 and a wall panel 7 is further attached thereon.

In order to fix the wall panel 7 to the base, first, when fixing the base 2 to the cloth foundation 1,
The bolts 9 are passed through the through holes in the vertical direction provided in advance on the base 2, and the seat plate 10 is connected to the base 2 and the cloth foundation 1.
Then, the base 2 is fixed with the anchor bolts and nuts 5 and 6. That is, the base plate 2 is fixed to the foundation 1 to fix the bolt 8 with the seat plate. Then, a long nut 11 is screwed into the upper end of the bolt portion 9, and using the long nut 11, an overhanging metal fitting 13 fixed to a vertical frame 12 (corresponding to a column in the frame structure) of the wall panel 7 is projected. Pull bolt 1 inserted into the part
4 is screwed into the long nut 11 from above, and the wall panel 7 is fixed by the nut 14 '.

[0004] A through hole through which the bolt portion 9 of the bolt 8 with a seat plate passes is previously provided at a corresponding portion of the floor panel 4, and a through hole through which a long nut 11 passes through a corresponding portion of the lower frame 15 of the wall panel 7. A burrow for burying the seat plate 10 is provided. In FIG. 5, reference numeral 27 denotes a bolt and a nut, which fix the pulling hardware 13 to the vertical frame 12.

[0005] By the way, such a structure is used for the wall panel 7.
The vertical pull-out force acting on the vertical frame 12 is supported by the strength of the base 2, and since the vertical frame 12 is not directly fixed to the cloth foundation 1, it is difficult to obtain a sufficient pull-out resistance. In other words, the base 2 needs structural strength similar to a beam. An anchor bolt 5 is used for the base 2 and the joist 3.
In addition to the through hole for inserting the upper part of the base plate, a through hole for passing the bolt 9 of the bolt 8 with the seat plate must be provided, and the damage to the base 2 and the joist 3 increases. Further, since the bolt 8 with the seat plate and the long nut 11 do not have any function of fixing the base 2 and the joist 3 to the cloth foundation 1, the base 2 and the joist 3
At the ends, the through holes of the anchor bolt 5 and the bolt 8 with the seat plate are inevitably close to each other, and there is a problem that cracks easily occur at these ends.

Further, a bolt 8 with a seat plate and a pulling bolt 1
4 is connected with the long nut 11 as an intermediary, but the upper portion of the long nut 11 is formed on the floor panel 4 so that the screwing amount (hanging) between the bolt 8 with the seat plate and the pulling bolt 14 is sufficiently taken. When the wall panel 7 is to be installed at a predetermined position as the next step, the wall panel collides with the upper part of the protruding long nut,
The installation work was sometimes cumbersome.

As shown in FIG. 6, a relatively long anchor bolt 5 ′ is fixed to the foundation 1, and its upper projecting part is penetrated through the base 2 and the joist 3, and is further stretched over the joist 3. There is a structure in which the floor panel 4 and the lower frame 15 of the wall panel 7 erected on the floor panel 4 are also penetrated and the upper end thereof is connected to a pull-in hardware 13 fixed to the vertical frame 12 of the wall panel 7. In this case, the vertical frame 12 of the wall panel 7 is
It is directly fixed to the foundation 1 by the anchor bolts 3 'and the anchor bolts 5', so that the pull-out resistance is large. However, the relatively long anchor bolt 5 ′ only penetrates the base 2 and the joist 3, and has no function of fixing the base 2 to the foundation 1. For this reason, in places where pillars are erected, such as corners of houses, and where vertical frames 12 of wall panels 7 are located, anchor bolts 5 ′ for fixing the upper structure such as pillars to the foundation 1 and the base 2 are attached to the foundation 1. The anchor bolts 5 for fixing are concentrated, and there is a case where a crack occurs at an end of the base 2 due to a defect caused by providing a through hole for this. In addition, when the wall panel 7 is erected, since the upper end of the relatively long anchor bolt 5 'protrudes above the floor plate 4, it takes time to arrange the wall panel 7 at a predetermined position by colliding with the upper end. There is a bad workability.

SUMMARY OF THE INVENTION The present invention relates to a binding structure between a foundation and a base (or a base and a joist, a base, etc.) and a column (a vertical frame of a wall panel, a column, etc.). The task is to provide a structure that allows the pulling bolt attached to the pillar and the anchor bolt fixed to the foundation to be connected with a sufficient hanging length, and to reduce the loss of the base and the like, and to provide the building hardware used for this binding hardware. I do.

[0009]

SUMMARY OF THE INVENTION In a wooden framed house, a binding structure such as a foundation, a base, a pillar, etc., is composed of an anchor bolt having a lower portion fixed to the foundation, a connecting nut with a washer, and a pull-in hardware. In the case of a wooden wall structure house, the base is a base and a joist placed on the base, and the pillar is a vertical frame constituting a wall panel. The foundation and the base are fixed to the foundation with anchor bolts, and a connecting nut with washer is screwed into the upper end of the anchor bolt. On the other hand, the lower end of the pull bolt of the pull metal attached to the pillar or the like is screwed into the above-mentioned connecting nut with washer to connect the pull bolt and the anchor bolt. As a result, the base or the like and the pillar or the like are tightly connected to the foundation by the pulling hardware, the anchor bolt and the connecting nut with washer.

The foundation is usually a cloth foundation made of cast concrete. The dimension that the upper end of the anchor bolt protrudes above the top end of the foundation is shorter than the height dimension of the base mounted on it, and can be screwed with the connecting nut with washer screwed in from the top of the base. . When the base or the like is made of a base and a joist, the total height is shorter than the total height of the base and the joist.

The connecting nut with washer includes a long nut portion having a washer portion and a screw hole passing through the center thereof. On the lower surface of the washer portion, a digging blade for cutting the surface of the intermediate cross member with rotation and embedding the washer portion itself in the surface of the intermediate cross member is formed. The upper and lower ends of the long nut portion project from the upper and lower edges of the washer portion. The length of the long nut protruding from the upper edge of the washer is the dimension (height) that allows the amount of threading (hanging) with the pulling bolt of the pulling hardware attached to the vertical frame of the column or wall panel to be sufficient. And In the case of a wooden wall structure house, the amount of protrusion may be substantially the same as or slightly lower than the thickness of the floor panel stretched on the joist. Further, the protrusion is often configured as a tool holder for a rotating tool.

The long nut portion may be formed integrally with the seat plate portion, or a long nut may be fitted into a through hole provided in the center portion of the seat plate portion as a separate component from the seat plate portion. It may be constituted by making it. In addition, a long nut is provided on the lower surface side of the seat plate, but a high nut as a separate component is welded to the upper surface of the seat plate of the conventional long nut with a washer in which the long nut does not protrude upward. Is also good.

The base is fixed to the foundation using an anchor bolt and a washer-attached connecting nut protruding from the top end of the foundation. The washer-attached nut is screwed from the upper surface of the base to the upper end of the anchor bolt using a rotating tool. As for the connecting nut with washer, as the screwing with the anchor bolt progresses, the digging blade provided on the lower surface of the washer begins to cut the surface of the base, etc., and the washer part finally sinks on the surface of the base, etc. State. If the upper surface of the washer coincides with the upper surface of the intermediate structural material such as the base, it becomes difficult to discharge shavings, etc., and the rotation resistance increases. The rotation of the nut stops automatically. Thus, the base and the like are securely and firmly fixed to the foundation.

Then, a pillar or the like is placed on a base or the like,
The lower end of the pulling bolt is screwed into the connecting nut with washer from above. Since the long nut portion of the nut with washer projects sufficiently upward from the upper edge of the washer portion, there is no shortage of screwing. The pulling bolt is often screwed into the connecting nut with washer until its lower end collides with the upper end of the anchor bolt. Therefore, the screwing amount (hanging length) between the pulling bolt and the washer-attached connecting nut may be larger than the dimension in which the long nut portion protrudes above the upper edge of the washer portion. Also, the pulling hardware is directly connected to the anchor bolts via the pulling bolts and nuts, so that the base and the pillars can be strongly fixed to the foundation.

As is apparent from the above, the connecting nut with washer of the present invention comprises a washer portion and a long nut portion penetrating the center thereof. The washer is convexly curved downward or is a flat disk. On the lower surface of the washer, a digging blade for cutting the upper surface of the base or the like with the rotation and embedding the washer itself on the upper surface of the base or the like is formed. The number of counterboring blades is usually about three, and is often formed along the tangential direction of the inner periphery of the long nut portion. The upper end and the lower end of the long nut portion of the joint nut with washer project from the upper edge and the lower edge of the washer portion, respectively, and the screw penetrates the center of the washer portion from the upper end to the lower end of the long nut portion. A hole is formed. An anchor bolt is screwed into a lower portion of the screw hole, and a pulling bolt is screwed into an upper portion. In the long nut portion, a portion above the washer portion may be formed by welding a high nut of another component. In some cases, a tool hook is provided in a portion of the long nut portion above the washer portion.

The connecting nut with washer used for a structure in which a floor panel is stretched on a joist and a column or the like is erected thereon is a floor panel in which a long nut portion has a dimension protruding from the washer portion. Shall be the same as or slightly lower than the thickness dimension.
When erecting pillars after placing floor panels or mounting and fixing wall panels, there are no protrusions on the floor panel surface, and the pillars and wall panels are slid sideways over the upper structural material and placed in place. Easy to work, such as can be placed. Further, the position at which the lower end of the pulling bolt is to be inserted and connected to the upper surface of the floor panel is easy to understand, so that there is no mistake. In any case, the connecting nut with washer is not a mere long nut, but by providing a washer, when the screw is screwed to the anchor bolt, the washer can press the base or the like from above to the base from above and tightly bind it. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a house 2 × 4 in which a wall panel 7 is divided into a floor panel 4, a joist 3 and a base 2.
Shows the binding structure connected to the fabric base 1 via the The base 2 and the joist 3 are fixed to the fabric foundation 1 with the anchor bolts 5 and the connecting nuts 16 with washers. And the vertical frame 1 of the wall panel 7
The lower end of the pulling bolt 14 of the pulling hardware 13 attached to 2 is screwed into the connecting nut 16 with a washer, and the upper nut 14 ′ is screwed in, whereby the pulling bolt 14 is directly connected to the anchor bolt 5. As a result, the wall panel 7, the joists 3 and the base 2 are tightly connected to the cloth foundation 1 via the anchor bolts 5, the connecting nuts 16 with washers and the pull-in hardware 13. The pulling bolt 14 is preferably screwed sufficiently into the washered connecting nut 16 until its lower end collides with the upper end of the anchor bolt 5 below.

The connecting nut 16 with washer (first example, FIG. 2) comprises a washer portion 17 and a long nut portion 19 having a screw hole 18 passing through the center thereof. In the first example, the washer 17 has a spherical shape curved convexly downward and has a diameter of 45 mm.
Having a diameter of On the lower surface of the washer 17, three digging blades 20 are formed at substantially equal intervals along the tangential direction of the inner periphery of the long nut 19 by a press 20 ′ from the upper surface side. The shape of the washer portion 17 is, in addition, a dish shape having a flat bottom (second example, FIG. 3) or a flat shape (third example,
Figure 4).

In the long nut portion 19, a portion 22 above the washer portion 17 is a hexagonally shaped tool hook portion, and this portion is similar to a commercially available high nut. In this embodiment, the length of the long nut 19 protruding above the washer 17 is 15 mm, which is slightly lower than the thickness of the floor panel 4 placed on the joist 3. Furthermore, the lower part 23 has a length of about 35
mm, which is smaller than the diameter of the upper part 22 which is a tool holder in this embodiment. The screw hole 18 of the long nut portion 9 may be φ16 mm or φ12 mm depending on the diameter of the anchor bolt 5 used.

The fixing plate 25 of the drawing hardware 13 has a projecting portion 26 formed at the lower portion, and the upper portion has a plurality of bolts.
The nut 27 is fixed to the vertical frame 12 of the wall panel 7. The pulling bolt 14 is a bolt drawn by a nut 14 ′. The pulling bolt 14 is inserted from above from a projecting portion 15 provided on a fixing plate 25, and is passed through a through hole provided in the lower frame 15 of the wall panel 1 through a through hole. Screw with nut 16. In the lower frame 15 of the wall panel 1, a through hole 17 for passing the pulling bolt 14 is formed.

This binding structure is constructed as follows.
When the cloth foundation 1 is cast, the anchor bolts 5 are buried in portions where the wall panels 7 are fixed. The projecting length of the anchor bolt 5 from the cloth foundation 1 is set according to the cross-sectional dimensions of the base 2 and the joist 3 so that the upper end thereof is slightly lower than the top surface of the joist 3.

The top end of the cloth base 1 is prepared, and the base 2 and the joist 3 are sequentially placed thereon. The connecting nut 16 with a washer is screwed onto the upper end of the anchor bolt 5 to put the base 2 and the joist 3 into the cloth. Fix to foundation 1. This fixing can be achieved by providing the washer-attached connecting nut 16 with the washer portion 17. Then, the upper surface of the washer portion 17 of the connecting nut 16 with washer is flush with the surface of the joist 3. The base 2 and the joist 3 are formed with through holes through which the anchor bolts 5 are inserted, and at least the upper portion has a diameter that allows the lower portion 23 of the washer-joint nut 16 to be inserted.

Next, a floor panel 4 is put on the joist 3. A fitting hole 28 is formed in the floor panel 4 in advance. The upper protruding portion of the washer-attached connecting nut 16 enters this fitting hole 28 and does not protrude from the upper surface of the floor panel 4. Then, the wall panel 7 is placed on the floor panel 4,
Overhang 26 of attracted hardware 13 fixed to wall panel 7
Through the pulling bolt 14. Then, the lower part of the pulling bolt 14 is passed through the through hole of the lower frame 15 of the wall panel 7 and screwed into the connecting nut 16 with washer.

The screw between the pulling bolt 14 and the connecting nut 16 with washer may be performed until the lower end of the pulling bolt 14 collides with the upper end of the anchor bolt 5 below. It is possible to confirm that the pulling bolt 14 is sufficiently screwed into the washer-attached nut 16 by the feel of the collision. Since the upper portion of the connecting nut 16 with washer projects upward from the washer portion 17 and the lower end of the pulling bolt 14 is screwed until it collides with the upper end of the anchor bolt 5, the connecting bolt with the washer 14 The screwing amount (hang) with the nut 16 is at least 15 mm, which is sufficient.
For this reason, reliable pulling and maintenance thereof can be performed.

[0024]

According to the present invention, since the anchor bolt fixed to the foundation and the pulling bolt of the pulling hardware are directly connected by using the connecting nut with washer, the connection between the pillar and the base (or the base and the joist) and the base is firm. It becomes something. This allows
The seismic resistance of a wooden framed house or a wooden wall structure house can be improved.

Since the connecting nut with washer has the long nut portion, the anchor bolt and the pulling bolt can be directly connected. At the same time, the base or the like can be fixed to the foundation using the anchor bolt by having the washer. For this reason, through holes for anchor bolts for fixing to the foundation and through holes for bolts with seat plates for connecting columns to the base, or relatively long anchors for connecting to the pull-in hardware are attached to the base. There is no need to provide a through hole, and there is little damage to the base and the like, and there is little possibility that cracks will occur at the ends. In addition, the base or the like can be fixed to the foundation at a location near the end, and the stability in the housing structure is good.

In the connecting nut with washer, since the upper portion of the long nut portion is protruded from the upper edge of the washer portion, a sufficient amount of screwing (hanging length) with the drawing bolt of the drawing metal can be obtained. Pulling strength can be obtained. In the connecting nut with washer, if the length of the protruding portion of the long nut portion from the upper edge of the washer portion is set shorter than the thickness of the floor panel, it protrudes from the surface of the floor panel when the floor panel is stretched. There is nothing and does not hinder the installation of pillars and wall panels. On the other hand, the position of the floor panel is determined by fitting the protrusion on the upper portion of the long nut into the through hole provided in the floor panel, and the upper surface of the long nut can be seen in the through hole.
The pull bolt is inserted and the position to be connected to the lower anchor bolt is immediately known. For this reason, work becomes easy and construction efficiency improves.
