関するものである。[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a column-beam joint structure in which the panel zone of the joint between a steel column with a box-shaped cross section and a steel beam with an H-shaped cross section is reinforced. It is.

ない。(Prior art) In general, when joining a steel beam with an H-shaped cross section to a steel beam with a box-shaped cross section, it is difficult to simply connect the steel beam to the side surface of the steel column. Since the outer bending rigidity is relatively small compared to the bending rigidity of the web, the strength of the web is not effective over the entire length and sufficient strength cannot be obtained.

、出願もした（特願平１−１１２４３３参照）。Therefore, Ganjin Toyama installed a vertical stiffener inside the beam joint position of the steel frame column, and by protruding the left and right edges of the vertical stiffener to the outside of the beam joint position, and joining the webs of the left and right steel beams to the protruding part. We developed a method to deal with the above problem and filed an application (see Japanese Patent Application No. 1-112433).

ものとは言えないことがわかった。(Problem to be Solved by the Invention) However, this type of method also has a processing problem in that a slit must be formed at the beam joint position of the steel column to pass the edge of the vertical stiffener. It turns out that it is still not perfect.

。(Means for Solving the Problems) This invention relates to a column-beam joint structure in which the panel zone of the joint between a steel column with a box-shaped cross section and a steel beam with an H-shaped cross section is reinforced. It is a joint structure of a steel column with a shaped cross section and a steel beam with an H shaped cross section, and the left and right steel beams are respectively connected to the outside of the left and right flanges of the steel column, and
The above object is achieved by having a configuration in which a vertical stiffener or a horizontal stiffener made of a plate or the like, or a vertical stiffener and a horizontal stiffener are separately attached to the left and right sides together with the diaphragm.
［実施例〕

至３段に（実施例では２段）ウェブ２ｂ、２ｂに対し直
交する方向（水平）に溶接することにより、左右別々に
一体的に取り付けられている。Similar to the vertical stiffeners 3゜3, the horizontal stiffeners 4, 4 are arranged in two or three upper and lower stages (two stages in the embodiment) inside the left and right flanges la, la of the steel column l (two stages in the embodiment), orthogonal to the webs 2b, 2b. By welding in the horizontal direction, the left and right sides are integrally attached separately.
又、水平ステフナ−４，４は垂直ステフナ−３，３と共

取り付けられいる（第７図乃至第１０図参照）。Further, when the horizontal stiffeners 4, 4 are installed together with the vertical stiffeners 3, 3, they are installed on both sides of the vertical stiffeners 3, 3 (see FIGS. 7 to 10).
更に、水平ステフナ−４は矩形板状若しくは三角形板状

防止する働きを有するが、応力を伝達する働きはない。In such a configuration, the vertical stiffener 3゜3 and the horizontal stiffeners 4, 4 are attached to the left and right flanges la, l of the steel column 1.
It has the function of increasing the bending rigidity of a and preventing local deformation of the column-beam joint, but it does not have the function of transmitting stress.
このような点で、上下ダイヤフラム５．５が左右鉄骨梁
２，２からの円滑な応力の伝達と柱・梁接合部に於ける
局部変形防止の双方の働きを有するのとは異なる。In this respect, the upper and lower diaphragms 5.5 are different from each other in that they function to both smoothly transmit stress from the left and right steel beams 2, 2 and to prevent local deformation at the column-beam joint.
