DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for attaching a member to a wooden building base, which can be used when mounting a reinforcing hardware or the like on a base fixed on a cloth foundation of a wooden building. .

[0002]

2. Description of the Related Art The base of a wooden building is laid on a cloth foundation and fixed by anchor bolts erected on the cloth foundation. Therefore, when a member such as a reinforcing metal fitting is mounted on the foundation, A square counterbore hole is machined on the bottom of the base in accordance with the bolt insertion through hole provided on the base, and a nut is fitted and fixed in the counterbore before placing the base on the cloth foundation. Then, after the base is installed, a member mounting bolt is screwed into the nut to fix the member.

[0003]

In the conventional structure as described above, a bolt insertion through hole and a counterbore are formed before the base is installed, and a nut is fitted and fixed in the counterbore. Even if the drilling is completely completed, if the base is installed with the nuts forgotten to be fixed, if the base is not removed again, it will not only be impossible to attach the members, but also The same inconvenience occurs when the base is installed in a state where the nut which should have been fixed has come off unexpectedly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will be described below with reference to the accompanying drawings. In FIG. 1, reference numeral 1 denotes a cloth foundation, 2 denotes a base laid on the cloth base 1, and 3 denotes a base 2
Columns 4 erected on the upper side, 4 are plate-shaped spacers interposed between the cloth foundation 1 and the base 2, 5 are reinforcing hardware disposed at the corners between the base 2 and the columns 3. is there. The base 2 is fixed on the cloth foundation 1 by anchor bolts (not shown) which are erected from the cloth foundation 1 as is well known in the art.

As shown in FIG. 2 and FIG.
Is formed by pressing a steel plate and integrally forming the same, and connects a vertical mounting plate portion 6, a horizontal mounting plate portion 7 connected to a lower end of the vertical mounting plate portion 6, and both sides of the both mounting plate portions 6, 7. The vertical mounting plate 6 is fixed to the pillar 3 by two horizontal bolt nuts 9 in upper and lower stages, and the horizontal mounting plate 7 is fixed to the base 2 by a vertical bolt 10.
And a plate-shaped nut 11.

The plate-shaped nut 11 is formed by pressing a steel plate and integrally forming it into a blade plate shape. A central portion 13 having a screw hole 12 and a handle portion 1 extending from the central portion 13 are provided.
4, which can be freely taken in and out of the gap 15 formed by the plate-shaped spacer 4 between the cloth foundation 1 and the base 2 from the lateral side.
5 can be operated from outside.

As shown in FIGS. 5 and 6, the screw hole 12 of the plate-shaped nut 11 is formed by forming a thread groove on the inside of a cylindrical portion 16 formed integrally with a central portion 13 downward by press working. The thickness of the plate-shaped nut 11 in the cylindrical portion 16 is slightly smaller than the height of the gap 15. The handle 14 is bent slightly downward at the base thereof so that the tip 14 a of the handle is located at an intermediate height of the gap 15.

The length of the handle portion 14 is the same as that of the screw hole 1.
2 is the distance from the center of the handle 2 to the tip 14a of the handle.
Is configured to be about half of the width of. Accordingly, as shown in FIGS. 3 and 4, when the lower end of the bolt 10 inserted into the through hole 17 formed in the center of the base 2 in the width direction is screwed into the screw hole 12, Tip 14a
Can be positioned substantially flush with the sides of the base 2,
The length of the handle portion 14 is configured such that the distance from the center of the screw hole 12 to the tip 14a of the handle portion is larger than half the width of the base 2, and the tip of the handle portion is moved laterally from the base 2. 14a may be made to completely protrude. Even in this case, if the handle 14 is turned so as to be pushed into the lower side of the base 2 (inside the space 15) immediately before the fastening of the bolt 10, the tip 14a of the handle can be prevented from protruding from the base 2. .

It is desirable that at least the peripheral edge 11a of the plate-shaped nut 11 which is in contact with the bottom surface of the base 2 is curved downward to prevent biting into the back surface of the base 2. In the illustrated example, the entire periphery of the plate-shaped nut 11 including the handle portion 14 is bent downward. As shown in FIG. 7, the handle portion 14 is bent stepwise at the base thereof,
The tip 14a may be arranged at an intermediate height of the gap 15. Further, as shown in FIG. 8, the screw hole 12 is formed in the central portion 13 of the plate nut.
8 and a ready-made nut 1 under the central part 13.
9 may be fixed by welding or the like.

In mounting the reinforcing metal member 5 on the base 2, after the base 2 is mounted on the cloth base 1, the plate-shaped nut 11 is laterally inserted into a gap 15 between the base 2 and the cloth base 1. The handle 14 is grasped from the side and inserted.
The lower end of the bolt 10 that is inserted downward into the through hole 17 is fitted into the screw hole 12 in a state in which the plate is positioned substantially immediately below the bolt insertion through hole 17 of the base 2. The handle 14 of the nut 11 is pinched and the plate nut 1
By rotating the bolt 10 in the tightening direction while preventing the co-rotation 1, the horizontal mounting plate 7 of the reinforcing metal member 5 can be fastened to the base 2 by the bolt 10 and the plate nut 11.

Although the reinforcing metal member 5 is exemplified as a member mounted on the base 2 by the member mounting structure of the present invention, it is a matter of course that the reinforcing metal member 5 is not limited to this.

[0015]

As described above, the structure for mounting the member on the base of the wooden building according to the present invention has a structure in which the plate nut is disposed in the space formed by the plate spacer between the cloth base and the base. Since the necessary members such as reinforcing hardware are mounted on the base by screwing member mounting bolts projecting downward from the base, it is necessary to machine a counterbore hole for fitting and fixing a nut on the bottom surface of the base. Since the plate-shaped nut can be put in and out of the gap by using the handle portion, the plate-shaped nut is inserted into a predetermined position under the base after the base is installed, and is arranged. It is possible to prevent the plate-shaped nut from rotating together with the bolt during the fastening operation by using the handle, and to securely fasten the bolt.

Therefore, according to the member mounting structure of the present invention,
While reducing the labor and time required for mounting the required members on the base, it is possible to reliably mount the members and to achieve a significant cost reduction.

Further , according to the structure of the present invention, the handle of the plate-shaped nut does not come into close contact with the base or the cloth base, so that the work of inserting the plate-shaped nut and preventing the co-rotation can be easily performed.

According to the second aspect of the present invention, not only can the plate-shaped nut be inexpensively constructed without using any separate parts, but also the entrance of the integrally formed cylindrical portion is a trumpet shape. By inserting the plate-shaped nut into the gap so that the entrance of the cylindrical portion is at the top, the bolt-through hole on the base side and the screw hole of the plate-shaped nut are completely formed. Even if they do not match, the tip of the bolt can be guided into the screw hole by the trumpet-shaped entrance of the cylindrical portion, and the workability is improved.
