Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cross-connecting metal fitting, and more particularly to a cross-connecting metal fitting that is useful for connecting the cross parts of the components of a frame structure such as a house.

[0002]

2. Description of the Related Art Conventionally, the frame of a house is generally constructed by using corners or round pipes, and the cross portion of vertical components such as columns and horizontal components such as beams and girders is formed by applying cross coupling fittings. Are connected.

When constructing a skeleton such as a house, especially in a mountainous region, construction is often performed on a sloping land. In such a case, for example, a vertical component (for example, a pillar) is used for a horizontal component (for example, a beam). , Girders, etc.) should be angle-corrected to be parallel to the sloping ground.

Conventionally, as a cross coupling metal fitting having such an angle correction function, for example, one having a structure as shown in FIG. 7 has been proposed. In this conventional structure, as shown in FIG. 7, a beam B that is cross-coupled to a column A is vertically moved with a bolt b that fastens the U-shaped joint part a and the beam B as a fulcrum. It can be rotated in any direction and the angle can be corrected.

However, in such a conventional structure, the joint portion must be attached and fixed to the column and the beam by using bolts and nuts one by one, and the attachment and fixing are complicated by turning and tightening with a turning tool such as a wrench. In addition to requiring a lot of trouble, a through hole for inserting a bolt must be provided in a component material such as a beam, drilling is required, and the unit price of the component material increases accordingly.

[0006]

According to the present invention, it is possible to efficiently carry out cross-joining, and in addition, secondary processing such as drilling is performed on the constituent materials such as columns, girders and beams to be joined. The purpose of the present invention is to provide a cross coupling fitting of this kind that does not require any.

DISCLOSURE OF THE INVENTION The present invention is a metal fitting applied to the connection of cross parts of structural materials such as frames, which comprises at least two joint parts capable of cross connection.
The cross coupling fittings are characterized in that the joint portions are pin-coupled so as to be rotatable and displaceable by a predetermined angle in the horizontal or vertical direction, and the constituent materials can be clamped and fixed by inserting a wedge. .

The components to be joined by the metal fitting of the present invention are typically columns, beams and girders, and also include horizontal members and vertical members for reinforcement.

The shape of the components joined by the metal fittings of the present invention is generally a steel round pipe or a square pipe, but other lightweight cross ropes (for example, H rope) having various cross-sectional shapes. The material is not particularly limited as long as it is rigid such as metal such as aluminum, plastic, and wood.

As the shape of the joint portion, for example, a U-shaped plate shape is suitable for a square pipe and a U-shaped plate shape for a round pipe. The shape is not particularly limited as long as it can be attached by being fitted from the outside. The material is usually metal such as iron, but it may be plastic.

Between both side plate portions of the joint portion, a wedge hole is formed so as to penetrate the joint portion by applying a wedge to fix the constituent material.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows an embodiment of a coupling fitting of the present invention provided with two joint portions 1 and 2 capable of cross coupling in two directions, for example, one vertical direction and one horizontal direction.

In FIG. 1, the first joint portion 1 on the left side is installed vertically, and the side opening 1 is provided with respect to a vertical member such as a pillar A.
It is formed in a U-shaped plate shape so that it can be mounted from the outer side through "a" with almost no gap.

Both side plates 1b before and after the first joint portion 1,
In 1b, when fitted to the pillar A, wedge holes 3 for driving the wedge w are formed at upper and lower two places in the portions 1b ₁ and 1b ₁ projecting outward from the pillar A. There is. The wedge holes 3 may be formed in at least one place, and the number thereof is not particularly limited.

The wedge hole 3 is for fastening the pillar A in the first joint portion 1 by the wedge tightening effect by inserting the wedge w, and the wedge hole 3 is formed between the side plate portions 1b and 1b. The pair of openings 3a and 3b that are formed have their inner end sides slightly recessed toward the pillar A side, and a slope corresponding to the slope of the wedge surface of the wedge w is provided between the openings 3a and 3b. .

The second joint portion 2 on the right side in FIG.

A horizontal member, for example, a beam B, which is cross-coupled to the pillar A is attached to the second joint portion 2 through the side opening 2a, and in order to fix the beam B in the attached state,
A wedge hole 3 including a pair of openings 3a and 3b is formed between the side plates 2b and 2b, as in the case of the first joint portion 1.

The side opening 2a of the second joint portion 2 is shown in FIG.
However, the opening may be downward, but the opening may be upward instead.

By bending the downwardly projecting stopper 5 at the tip of the second joint portion 2, for example, the tip of the coupling plate portion 2c, the tip of the beam B can be restricted to a fixed position. Stopper 5 is shown in more detail in FIG.

When the beam B is cross-coupled to the pillar A by applying the metal fitting of the present invention shown in FIG. 1, the first joint portion 1 is first attached to the pillar A which is vertically installed and fixed. The first joint part 1 is tightened and fixed to the pillar A by vertically mounting it through the side opening 1a and then driving the wedge w into the wedge hole 3 of the joint part 1.

In the state where the first joint portion 1 is attached and fixed to the pillar A, the second joint portion 2 extends laterally from the rear surface side of the coupling plate portion 1c of the joint portion 1, so that the joint portion 1c. Beam 2 through its side opening 2a
The beam B can be cross-coupled to the column A by fitting one end of the beam B into the wedge hole 3 and then inserting the wedge w into the wedge hole 3 to tighten and fix the beam B in the joint 2.

In this cross-coupling state, the beam B can be pivotally displaced in the vertical direction by a predetermined angle with respect to the pillar A with the pin 4 as a pivot, and the cross-coupling angle can be corrected.

The two-way cross-coupling metal fitting shown in FIG. 1 can be used as a horizontal two-direction cross-coupling metal fitting as shown in FIG. It can be applied when the reinforcing material D is cross-bonded. In this case, the horizontal reinforcing member D can be pivotally displaced with respect to the girder C in the horizontal direction by a predetermined angle with the pin 4 as a pivot.

FIG. 3 shows an example in which the installation direction of the pins 4 in the two-way cross coupling fitting shown in FIG. 1 is changed from the horizontal direction to the vertical direction. By doing this, pillar A
On the other hand, the beam B can be cross-coupled so as to be horizontally rotatable by a predetermined angle.

FIG. 4 shows one embodiment of the two-way cross coupling fitting of the present invention which can be applied to cross coupling with a horizontal member such as a girder C at the upper end of the pillar A.
