Description

[Detailed explanation of the invention] To attach flints and braces used in wooden construction, cutouts are made in the beams, girders, and columns where the end faces of the flints and braces touch, and the flints and braces are inserted into each end. and girders, beams, or columns are connected with bolts. However, when the house shakes due to an earthquake or typhoon, and compressive force is applied to the flints and staves, these flints and staves fully serve the role of reinforcement, but when tensile forces are applied, the flints and staves act as reinforcements. If it is removed from the beams or columns, it will not be of any use for reinforcement.

The present invention aims to provide flints and cushions that are effective for reinforcement even when compressive force or tensile force is applied to the flints and cushions when a house shakes due to earthquakes, typhoons, etc. .

In the present invention, holes 5 and 6 for bolt insertion are provided at the center of the outer end plates 3 and 4 of the bisected cylinders 1 and 2, respectively.
Nuts 7 and 8 are fixed to the inner surfaces of the outer end plates 3 and 4 so as to communicate with the bolt insertion holes 5 and 6, and bolts 9 and 10 that are screwed into the nuts 7 and 8 are provided. , 2 are provided with a right-hand thread and a left-hand thread on the inner surfaces thereof, and a right-hand thread and a left-hand thread are provided on the outer surfaces of the right half and the left half, respectively.
This relates to a metal flint, which is characterized by being connected by threading to the inner surface of the metal flint. Note that a part of the middle of the connecting cylinder 11 is made flat so that a spanner or the like can be fitted therein. 12 is a beam, 13 is a girder, 14
is a pillar.

To install the flints and supports of this invention, make a counterbore in each part of the girder, beam, or column that each end surface touches so that each end is stable, and then install the flints and supports in the recesses created by the counterbore. Insert each end, and drill holes 15 and 16 for bolt insertion into the girder, beam, and column toward the screw holes of nuts 7 and 8 fixed to the end plates of cylinders 1 and 2, and insert the bolts into these holes. 9 and 10, respectively, and screw them into the respective nuts 7 and 8 to connect the flints and braces to the beams, beams, and columns.

In the case of the present invention, these are connected to girders, beams, columns, etc. with bolts in the axial direction, so if the house shakes due to earthquakes or typhoons, the fireworks and the case will be damaged. Even when tensile force or compressive force is applied, flints and braces do not come off from girders, beams, columns, etc., and work reliably to reinforce them.

Also, although the depth of the counterbore holes differs somewhat, in the flint and method of the present invention, the total length of the cylinders 1 and 2 can be changed by rotating the connecting cylinder 11, so Even if there is a difference in the depth of the hollow hole, it is possible to fit a flint or a mallet so that each end surface reaches the bottom of the hole.

In addition, there are some differences in the dimensions of each area depending on the region, such as Kyoma, Kaga, Echizen, etc., but the dimensions of the hinuchi and katsue of this invention can be adjusted by rotating the connecting cylinder. No matter where it is used, it can be installed in such a way that the end face is securely attached to the counterbore.
Therefore, the flints and countermeasures of the present invention have an excellent effect in that they work reliably as reinforcement regardless of the depth of the counterbore and regardless of where they are used.
