Description

  The present invention relates to a connection between a column and a beam, and more particularly to a connection structure between a rectangular column and a rectangular beam.

Timber and steel frames are used for structural materials such as building columns and beams, and the columns and beams of wooden buildings are connected by mortise or wing plate bolts, and steel frame buildings are square steel pipe columns. The cross-section beam and the square steel pipe beam are joined by welding, or the bracket is welded to the square steel pipe column and the steel pipe beam, and the brackets are bolted together.
As an example of the bolted brackets, a connection structure between a column and a beam in Japanese Patent No. 2759603, and a connection structure between a column and a beam made of a decorative material-coated square steel pipe in Japanese Utility Model Registration No. 2515569 are proposed.

However, the pillars and beams made of wood have a weak point particularly in the connecting portion in terms of strength, and it is difficult to process the connecting portion such as mortise processing, which requires skill.
On the other hand, columns and beams made of steel frames are strong, but welding causes distortion of the material and has problems with workability on site. In addition, when the brackets are joined with bolts, the strength of the joint is not sufficient.

In recent years, wooden buildings have been strengthened with earthquake-resistant structures, etc., but there is a limit between timbers. Therefore, a combination of timber and steel frames is conceivable. If it does, it will be a wooden building with sufficient strength, but it needed a device at the joint.
Japanese Patent No. 2759603 Utility Model Registration No. 2515569

  In view of the above, the present invention provides a case where a square column and a square beam are firmly coupled with a bracket and a bolt without welding, and the column or beam is made of steel pipe or wood. Therefore, it is intended to provide a coupled structure of columns and beams that can be used in any combination.

  In order to solve the above-described problem, the column-beam connection structure according to the first aspect of the present invention is a structure in which a square beam is coupled to both side surfaces adjacent to each other with a corner portion of the square column interposed therebetween.

And the vicinity of the end of one of the beams is sandwiched, and a corner connecting bracket is brought into contact with an inner corner portion constituted by the flat plate connecting bracket and the other beam orthogonal to the flat plate connecting bracket. Both of the substantially L-shaped ones are in contact with the side surfaces of the flat joints at the inner corners and the other are in contact with the side surfaces of the beams at the inner corners In addition, there are provided substantially triangular horizontal plate portions at the upper and lower portions sandwiching the inner corners of both sidewall portions, and a flat plate joint fitting sandwiching the column, and an L-shaped coupling fitting facing this A through-bolt is inserted between one piece of the L-shaped fitting and between the other piece of the L-shaped fitting and the inner side surface of the column and fastened with a nut, and between both pieces of the L-shaped fitting and the side wall of the corner fitting. A combined structure of pillars and beams, in which bolts are inserted and fastened with nuts.   2. The column / beam connection structure according to claim 1, wherein the beam is a steel pipe, and a notch is provided in each of the upper surface and the center of the lower surface of the mouth end of the beam.   2. The column / beam coupling structure according to claim 1, wherein the beam is made of wood, and a notch groove extending from the upper surface to the lower surface is provided at the center of the mouth end of the beam. It is a structure in which a square steel pipe beam is joined to the three sides of a square column, and the end of the beam abuts each other on both opposite sides of the column, and near the ends of the column and both beams Both ends of the beam are clamped by flat plate fittings, and the end of the beam is abutted against either one of the other opposing side surfaces of the column via the flat plate fittings. Corner connecting brackets are in contact with the inner corners constituted by the connecting brackets, one of the corner connecting brackets contacts the side surface of the flat corner metal fitting of the inner corner portion, and the other contacts the side surface of the beam of the inner corner portion. It has both substantially L-shaped side wall portions, and is provided with substantially triangular horizontal plate portions at the upper and lower portions sandwiching the inner corner portions of both side wall portions. Insert a through bolt between the side wall of the flat joint and the corner joint. Are together fastened by the nut, the notches each provided at the central portion of the upper surface and the lower surface of the mouth end of the side of the beam perpendicular to the flat joint device further both corners across the beam perpendicular to the flat joint device A coupling structure of a column and a beam, wherein a through bolt is inserted between the side walls of the connection fitting and fastened with a nut . A structure in which square steel pipe beams are joined to the four sides of a square column, and the ends of the beam and the ends of both beams collide with each opposite side of the column. Both sides in the vicinity are clamped by a flat joint, and the opposite ends of the column are respectively opposed to the opposite ends of the beam via the flat joint, and the upper ends of the ends of the colliding beams Cutouts are provided at the center of the lower surface, and corner connecting brackets are in contact with the inner corners formed by the beams and the flat joints on both sides of both beams. It has both substantially L-shaped side walls that abut the inner corner flat plate fitting and the other abuts the side of the inner corner beam. A triangular horizontal plate is provided, and both sides Coupling structure columns and beams, characterized in that through each junction fitting and the beam between opposing side walls of each corner connection bracket sandwiching the bolt is fastened by inserted through the nut.
