DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for joining hardware, columns, and the like used for joining columns, beams, and the like of a wooden building, and more particularly, to joining columns, beams, and the like in a rigid frame structure of a wooden building. The present invention relates to a method for joining hardware, columns, and the like used in the present invention.

[0002]

2. Description of the Related Art Conventionally, when a column or a beam is in contact with a rigid frame structure of a wooden building, for example, as shown in FIG.
In order to join the beam b to the column a fitting metal c is previously fitted to the column a by a known method. Then, a metal fitting c is inserted into a pair of parallel grooves b1 'formed in the column b, and a pair of grooves b2' formed in the column b and a drift pin d is inserted into a hole c 'formed in the metal c.
A method of inserting and fixing the same has been implemented.

[0003]

However, the above-mentioned method minimizes the loss of the cross section by using the metal fitting c when drilling a hole in a column or a beam in the frame structure to perform a frame assembly. However, since the joint between the hardware and the wood is not enough, the drying may cause the looseness and vibration of the bolts and bolts due to the drying of the wood. Was dissatisfied.

The inventor conceived that the bonding metal c fitted on the pillar a was preliminarily coated with an adhesive and inserted into the groove b1 'of the beam b. The agent was dropped, and the adhesive did not spread in the groove, so that it was impossible to realize it.

SUMMARY OF THE INVENTION An object of the present invention is to provide a metal joint for further strengthening the rigid frame structure by ensuring the joint of a column and a beam in a wooden building in order to solve the above problems. I do.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, a method of joining columns and beams according to the present invention uses a bridge having a hole for a drift pin or bolt from a single metal plate. Similarly, a plate having a pair of side plates having holes for drift pins or bolts is punched through the portion, and the pair of side plates are bent from the bridge portion so as to face each other, and the pair of side plates are located at positions facing each other. It has a notch for guiding the drift pin, each side plate is provided with a plurality of ridge-shaped horizontal projections formed by pressing on both sides, and an adhesive is applied in a dot-like manner at appropriate places on the plurality of ridge-shaped horizontal projections. Then, parallel vertical grooves corresponding to the pair of side plates are formed in the columns, the side plates are inserted, bolts are inserted into the holes for the drift pins or bolts of the pair of side plates, and the columns are joined to the columns with nuts. Hardware And summarized in that to fix attach fit.

[0009]

As shown in FIG. 1, a metal fitting 30 is provided for connecting a pillar 20 to a beam 10 in a rigid frame structure of a wooden building. The hardware 30 is attached to the beam 10.
Are formed at two places, and a pair of vertical grooves 21 are formed in the column 20 for receiving the hardware.

The metal piece 30 is formed of a pair of side plates 3 having a hole 36 for a drift pin through a pair of bridge portions 31 having a hole 32 for a drift pin from a single metal plate.
The plate with 3 is punched. Then, the plate is bent from the bridge portion 31 and the bridge portion 31 is bent.
While forming a connection, the side plates oppose each other to form a beam box as a whole.

Each side plate is formed with two vertically aligned bolt holes 36 and a notch 34 having a guide slope 35 above the bolt holes 36. The pillar 20 has a drift pin hole 221 at a position corresponding to the drift pin hole 36 and the notch 34, and a bolt hole 222 at two locations below the drift pin hole 221.

As shown in FIGS. 1 and 2, each side plate is formed with six ridge-shaped projections 37 which are pressed on the front and back surfaces and extend in the horizontal direction.

The hardware 3 is inserted into the hole 11 of the beam 10.
Then, the column 10 and the hardware 30 are combined with the drift pin D1. Further, the metal fitting 30 is fixed to the beam 10 using a bolt (not shown).

In this state, one drift pin D2 is inserted into the uppermost drift pin 22 of the drift pin holes 22 of the pillar 20. Next, FIGS. 2 and 3
Applying adhesive A in dots at appropriate locations on the respective ridge-like projections 37 as shown in (A). And Kino Kikkake to guide the draft pin D2 of the pair of side plates 33 and inserted using the already pair of guide slope 35 of each insert with cutouts 34 in the vertical groove 21 of the pillar 20 of the hardware 30 The drift pin D2 is positioned in contact with the bottom.

Then, bolts D3 are inserted into the remaining two holes 22 of the column 20, respectively, and the two holes 36 of the hardware 30 are searched and screwed in, and tightened with nuts (not shown).
Is fixed to the hardware 30.

In the above embodiment, the beam 10 and the column 20 are joined by the metal hardware 30, but the present invention is not limited to this, and any combination of the beam and the column, the beam and the beam, or the beam and the base can be joined. .

【The invention's effect】

As described above, a plurality of ridge-shaped projections formed by pressing both sides are provided horizontally on each side plate of the joint metal such as a column and a beam of the present invention, and the ridge-shaped projections are bonded to appropriate positions on the ridge-shaped projections. The agent is applied in the form of dots, parallel vertical grooves corresponding to the pair of side plates are formed in columns, the side plates are inserted, and bolts are inserted into the holes for the drift pins or bolts of the pair of side plates. When the column and the joining hardware are fastened and fixed with a nut, the ridge-like projections bite into the wood and increase the frictional force between the columns and beams.

As a result, the hardware is used as a rame for wooden buildings.
When used in a rigid structure, the joints of columns and beams are
The strength of the entire structure is dramatically improved. For this, wood
Prefabrication of architecture can be unitized, and
Work can be minimized and construction period can be significantly reduced.
Not only has the effect of enabling cost reduction, etc.
Horizontal ridges prevent the adhesive from dripping.
Use of adhesives, which was not feasible until now,
And uneven application of the adhesive was eliminated.

Further, the drift pins of the pair of side plates are provided.
Or insert the bolt exclusively into the bolt hole and use the nut to
The adhesive is tightened and fixed so that the adhesive is in the groove
The bonding area of the spreading adhesive increases, and metal and wood for joining are used.
The friction between the joints and the bonding force by the adhesive are dramatically improved,
The strengthening of the men's structure has become a reality.
