Description

Description: TECHNICAL FIELD The present invention relates to a multidirectional joint applied when building materials such as columns, beams, and girders of buildings are joined together in an orthogonal manner.

[Prior Art] As a conventional technology, there is JP-A-1-102152.
This publication discloses a joint element in which a plurality of fitting recesses are formed in a plate material having a plate width twice the plate thickness at intervals equal to the plate thickness, and a length of the plate material a plurality of times the plate thickness. And a joint element in which the fitting recess is formed as a cutout is disclosed.

[Problems to be Solved by the Invention] In the above multi-directional joint, precise fitting precision is required when a plurality of fitting recesses are cut into a plate material to manufacture a joint element, and therefore each fitting recess is required. There is a problem that the number of machining steps for notch machining is complicated and inefficient.

The present invention aims to solve the above problems.

[Means for Solving the Problems] In the multidirectional joint of the present invention, a plate member having a plate width twice the plate thickness is provided with a notch portion having a length equal to the plate thickness and a depth equal to the plate thickness. A first joint element group in which a suitable number of first joint elements each formed by being recessed along the direction are aligned in parallel in the same direction with their plate thickness directions aligned, and one side An appropriate number of regular hexahedron-shaped joining walls having six square faces each having a length equal to the plate thickness, and a plurality of fitting recesses having a shape equal to the joining walls are formed with the joining walls separated from each other. Second joint element group in which a suitable number of second joint elements respectively joined to the bottom surface of the cutout portion are oriented in the same direction and juxtaposed in the same direction in the same plate thickness direction. It has a structure in which and are crossed at right angles and joined.

[Operation] An appropriate number of first joint elements each made of a plate material having a plate width twice the plate thickness, each having a notch portion having a length multiple times the plate thickness and a depth equal to the plate thickness are provided. First in parallel
An appropriate number of second joint elements each made of a joint element group and a plate material having a plate width twice the plate thickness and having a plurality of fitting recesses each having the same length and depth as the plate thickness are provided. When assembling a multidirectional joint with the second joint element group arranged in parallel, a regular hexahedron shape having six square faces each having a side length equal to the plate thickness is formed on the bottom surface of the cutout portion of the first joint element. A second joint element is produced by joining several joining walls so that a plurality of fitting recesses are formed in the cutout portion with the joining walls separated from each other.

EFFECTS OF THE INVENTION Since the present invention is configured as described above, the multidirectional joint can be easily assembled by sequentially joining the first and second joint elements that are easy to process and have a simple form. At the same time, since the joint area of both joint elements increases, the structural strength of the multidirectional joint itself and the joint strength between the multidirectional joint and the building material can be increased, and the number of building materials connected to the multidirectional joint can be increased. Can be increased.

In particular, since the second joint element can be formed by joining the joint wall to the bottom surface of the cutout portion of the first joint element, precise cutting work for forming the fitting recess of the second joint element is unnecessary. Therefore, the number of steps for producing the second joint element can be reduced and the second joint element can be efficiently produced.
