METAL FIXTURE FOR RIGID JOINT OF WOODEN STRUCTURE

PROBLEM TO BE SOLVED: To provide a metal fixture for joining a column and a beam, which is a most important in Rahmen construction as a framework construction of a wooden building.SOLUTION: A beam receiving metal fitting 3 formed from a steel piece bent into a C-shape including an attachment plate 3a which is a web surface to come in contact with a column surface and has bolt holes projecting outward, side-face plates 3b which have bolt holes in the side faces projecting at both right and left sides of the attachment plate 3a, and rest plates 3c and 3d which extend horizontally from the bottoms of the attachment plate 3a and the side-face plates 3b, and a U-shaped metal fitting 4 formed from a steel piece bent into a C-shape having a web surface at the top including a pressing plate 4a having a trapezoidal end of the web to come in contact with a column, an angle plate 4c which is formed from the pressing plate bent at the right angle and has bolt holes at the vertical plane, and insertion plates 4b which have bolt holes and extend downward from a part of the web at both sides are overlapped at a junction between the column and a beam, so that the side-face plates 3b and the insertion plates 4b are connected with bolts 5 to form a metal fixture for a rigid joint.
