Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal fitting for joining a column base and a base in a wooden framework.

[0002]

2. Description of the Related Art First of all, the column base and the base of the wooden frame are
A base is installed and fixed on the upper surface of a concrete cloth foundation, and further, the lower end surface of the column base is placed on the base and fixed with a dedicated hardware (see Japanese Utility Model Laid-Open No. 1-177304).

[0003]

In the above-mentioned conventional joint structure, since the lower end surface of the column base rests on the base, the column base sinks into the base due to the weight of the building itself, and as a result, the building is It has the drawback of being deformed.

The object of the present invention is to solve the above-mentioned conventional drawbacks and to provide a metal joint which can be directly installed and fixed on a concrete foundation without placing the column base on the foundation. It is what

[0005]

In order to solve the above-mentioned problems, according to the present invention, an abutting portion which is abutted against a side surface of a lower end of a column base and fixed to the column base, and which is installed on a foundation thereof. From the installation part that is fixed to the anchor bolt of the foundation, and the insertion part that is inserted into the slit at the end of the base that is placed above the installation part and that is fixed by a fixing member such as a bolt that is inserted from the side surface of the base. It is characterized by becoming.

[0006]

According to the above construction, the joint metal is fixed to the side surface of the column base like the conventional metal, but since the insertion part is inserted and fixed in the slit of the base end face, the base end face is fixed. It is possible to place it on the side of the base, that is, to install the column base directly on the foundation and join it to the base.

[0007]

EXAMPLE In FIG. 1, (1) is a concrete cloth foundation, (2) and (2) are wooden bases installed on the cloth foundation (1), and (3) is a base (2) ( Between 2), the wooden column base installed directly on the upper surface of the cloth foundation (1) is shown. Foundation
At the end face of (2), two slits (4) and (4) with a constant depth are formed at intervals in the width direction of the base (2) so as to penetrate above and below the base (2). Has been formed. Further, the base end between the slits (4) and (4) is cut off to form a groove (5) at the center of the end face of the base (2) in the width direction. Further, so that the slit (4) (4) is penetrated, the base
(2) A bolt hole (6) is formed in the vicinity of the upper end portion, and a pin insertion hole (7) is formed below the bolt hole (6) so as to penetrate from one side surface to the other. Among them, the bolt hole (6) on the upper side is inserted with a bolt (9) which is attached at the factory in advance, and is temporarily tightened with a nut. On the other hand, a pair of upper and lower bolt holes (8) and (8) are formed at the lower end of the column base (3) so as to be parallel to the cloth foundation (1) when installed.

The joining metal article (10) of the present invention is formed by bending a metal plate and is integrally formed, and (11) is a horizontal installation part made of the metal plate. Both ends in the width direction of () are bent upward at substantially right angles to form a pair of insertion portions (12) (12) that are parallel and perpendicular to each other. On the other hand, one end in the longitudinal direction of the installation portion (11) is similarly bent upward at a substantially right angle to form a vertical contact portion (13). As shown in FIG. 3, the installation part (11) has a cloth foundation.
A bolt hole (15) is formed to insert the upper end of the anchor bolt (14) embedded in (1). On the other hand, the contact portion (13) is formed with a pair of upper and lower bolt holes (16) (16) corresponding to the bolt holes (8) (8) of the column base (3).

Bolt holes (17) are formed in the insertion parts (12) (12) near the upper end thereof, and pin insertion holes (18) are further formed below the bolt holes (17).
Are formed. The bolt hole (17) is opened to the upper end side by a V-shaped notch (19) notched from the upper end of the insertion part (12), whereby the bolt of the base (2) is from above.
(9) is dropped so that it can be inserted.

A column base (3) and a base using the above-mentioned hardware (10)
Explaining the joining method of (2), first, the contact portion of the metal object (10).
The outer surface of (13) is brought into contact with the side surface of the lower end of the column base (3), and the bolt hole (8) of the column base (3) and the bolt hole (16) of the contact portion (13) are aligned. After positioning, the bolts (21) are inserted so as to penetrate through the bolt holes (8) and (16) in this state, and the metal object (10) is fixed to the column base (10). Usually, the metal object (10) is carried to the site in a state of being fixed in advance, but it may be attached at the site. And when installing the hardware (10) on the cloth foundation (1), the bolt hole of the installation part (11)
Insert the upper end of the anchor bolt (14) into (15),
Tighten the nut (20) to secure the hardware (10) onto the cloth foundation (1).

As shown in FIG. 1, the base (2) is provided on both sides of the column base (3).
When (2) is joined linearly, a pair of metal fittings (10) (1
0) are arranged symmetrically, one of upper and lower bolt holes (16) is selected, and they are fastened and fixed together by one same bolt (21).
Further, in the case of a corner where the bases (2) and (2) are joined in a right angle direction, for example, one direction uses the bolt hole (16) at the upper part of the contact portion (6) and the other direction in the other direction. , Lower bolt hole (16)
Insert the bolts (21) in the shape of a cross and secure them using.

Next, the base (2) is cut into its slits (4).
The insertion parts (12) and (12) are inserted into (4) and installed on the upper surface of the cloth foundation (1). Further, the end of the base (2) is placed on the upper surface of the installation portion (11). At that time, by installing the bolt (9) previously attached to the base (2) so as to drop it from the notch (19), the bolt (9) is automatically inserted into the bolt hole (17). It fits in and allows the base (2) to be positioned.
In this state, the pin insertion hole (7) formed in the base (2) and the pin insertion hole (18) of the insertion part (12) are aligned with each other, and these pin insertion holes are inserted from the side surface of the base (2). The base (2) is fixed to the column base (3) and the cloth foundation (1) side by driving the drift pin (22) into the holes (7) and (18) and tightening the bolt (9). become.

The upper end of the anchor bolt (14) and the column base
The ends of the bolts (21) for fixing (3) are the same as the above groove.
By arranging it in (5), it is possible to avoid interference with the base (2).

[0014]

As described above, in the metal joint of the present invention, the base and the column base can be fixed in a state where the column base is directly installed on the foundation. There is no need to mount and join the column base. Therefore, it is possible to eliminate the inconvenience that the column base is embedded in the upper surface of the base and the frame is deformed.
