DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for joining wooden frames in a cross direction.

[0002]

2. Description of the Related Art In a wooden building, a so-called tenon joint using a tenon and a tenon hole is generally used to join a first axial member such as a pillar or a purlin to a second axial member such as a girder or a beam. In recent years, a method of joining both vertical and horizontal materials via a joint fitting has been adopted because of the complexity of processing a tenon or a tenon hole and joining work.

However, in the conventional examples, the first and second frame members are all joined at a fixed joining angle (for example, 90 °).
It can be applied only when joining at different angles, and when the joining angle is different, the structure has to be joined using a different kind of joining fitting.

An object of the present invention is to provide a joining apparatus which can reliably join both members by following the joining angle of the first and second frame members.

[0005]

Means for Solving the Problems At the upper and lower ends of the mounting piece, the upper regulating piece and the lower regulating piece are set so that the lower regulating piece is below and above the upper regulating piece. A first joint is formed by being connected to each other, and the first joint is fastened to a side surface of the first framing member at the mounting portion to protrude therefrom, and is fixed to the second framing member. The cylindrical connecting cylinder portion of the second fitting is attached to the lower regulating portion through a guide gap between the upper regulating portions of the first fitting in an engagement notch formed in an end surface of the second frame member. A configuration in which the connection cylinder portion is mounted on the upper edge of the concave arc shape of the piece, and the connection cylinder portion is pivotally attached to an end portion of the second frame member through a fitting notch or a through hole provided in the upper regulating portion piece. I do.

[0006]

The cylindrical connecting cylinder in the engagement notch, which is placed on the upper edge of the lower restricting piece of the first joint fitting through the upper restricting piece of the first joint fitting fixed to the first frame member. Due to the concave arc shape of the lower restricting piece, the lower restricting piece (of the second joint fitting fastened to the second framing material) is independent of the joining angle between the first framing material and the second framing material. Is always received in the fixed position of the upper edge. Then, the first shaft assembly and the second shaft assembly are joined to each other via the first and second joint fittings by a fastening rod penetrating the connection tube, and assembled to the end of the second shaft assembly. The connecting cylinder or the connecting rod is restricted from moving upward with the second frame by the upper restricting piece of the first joint fitting, and downward moving with the second wood by the lower restricting piece. Thus, the joined state of the first and second shaft assembly members is reliably maintained.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a longitudinal sectional view of an apparatus for joining wooden frames in a cross direction in a wooden building according to an embodiment of the present invention. FIG. 2 is a sectional view taken along line xx of FIG. FIG. 4 is a perspective view of a joining fitting.

In the apparatus of the embodiment, the first joint 1 and the second joint 2 are assembled to the first shaft assembly 3 and the second shaft assembly 4 which are joined to each other in the cross direction, and are obtained by assembling with each other. .

In the embodiment, the purlin is used as the first frame member 3 and the climbing beam is used as the second frame member 4. However, the joining of other beam members such as beams, columns and the like is performed. Of course, it can be applied to

In the first joint 1, upper regulating pieces 8, 8 are positioned above upper ends of mounting pieces 7 provided with a pair of upper and lower through holes 6, 6 for fastening bolts 5. The lower regulating pieces 9, 9 are arranged continuously below the both ends, with the lower regulating pieces 9, 9 being located inside the upper regulating pieces 8, 8. The edges 10, 10 are formed in a concave arc shape,
The lower edges of the upper regulating pieces 8, 8 are provided with fitting notches 11, 11 located on the arc-shaped (arc-shaped) axis of the upper edge 10.

The second metal fitting 2 has a pair of through-holes 6 through which a drift pin (in short, a fastening rod is sufficient) 12 is inserted.
The connecting tube portion 14 is provided at one end of a cylindrical mounting tube portion 13 provided with ', 6' in a direction perpendicular to the mounting tube portion 13.

The connecting cylinder portion 14 is partially (semicircularly) coincident with the arc shape of the upper edge 10 of the lower restricting piece 9 and is partially coincident (diameter of the drift pin 12A). Since the inner diameter becomes larger, a pair of reinforcing pieces 14a, 14a are fixed inside and a drift pin (in short, a fastening rod) 12A for penetrating through the reinforcing pieces 14a, 14a is sufficient. The through holes 15, 15 having a diameter substantially matching the outer shape of the drift pin 12A are provided.

The first joint 1 is provided with the mounting piece 7
The fixing bolt 5 screwed into the first shaft assembly 3 through the through hole 6 is fixed to the side surface 3a of the first shaft assembly 3 so as to protrude therefrom, and the second joint 2 is connected to the second shaft 2 A through hole 17 formed in a back wall 16a of an engagement notch 16 provided in an end face 4a of the assembly 4
And a through-hole 18 provided in the end 4A of the second shaft assembly 4 and a through-hole 6 'aligned with the through-hole 18.
The second shaft assembly member 4 is fitted with a drift pin 12 in a state where the connection tube portion 14 is accommodated in the engagement notch 16.
Attach and secure.

The assembly of the first joint 1 to the first shaft assembly 3 and the assembly of the second joint 2 to the second shaft assembly 4 are performed at a factory, respectively. The work of assembling the first joint 1 protruding from the assembly 3 and the second joint 2 fastened to the second shaft assembly 4 is performed on site.

Thus, the second joint member 2 is attached to the second frame member 4.
Is dropped into the first joint fitting 1 through the upper regulating pieces 8, 8 of the first joint fitting 1 (fixed to the first frame member 3), and the lower connecting regulation is performed. Upper edge 1 of piece 9, 9
When the connection cylinder portion 1 is placed on the connection cylinder portion 0, the connection cylinder portion 1 is formed due to the cylindrical shape of the connection cylinder portion 14 and the concave arc shape of the upper edge 10.
4, the second shaft assembly 4 is combined with the upper edge 10, ie, the first shaft assembly 3 in a positional relationship (intersecting angle set by the two shaft assemblies 3 and 4). By inserting the drift pin 12A into the through hole 18A provided in the material 4 and the through hole 15 in the connection tube portion 14, and fitting the drift pin 12A into the fitting notch 11, the embodiment apparatus can be obtained.

In the embodiment, the connection tube 14 of the second metal fitting 2 (the through hole 15) and the fitting notch 11 (the drift pin 1) are used.
2A, the drift pin 12A is driven into the through-hole 18A, and the first and second joint fittings 1 and 2 are connected. The second frame members 3 and 4 are joined,
A through hole may be used for the upper regulating piece 8 instead of the fitting notch 11.

The engagement between the drift pin 12A and the fitting notch 11 (through-hole) is performed from the side surface 3a of the first shaft assembly 3 to the second shaft assembly 4
When an external force is applied in the direction in which the end portion 4A of the first member is separated, the separation is prevented.
