Description

[Detailed description of the device] [Industrial applications]

The present invention relates to a joint structure between a steel column having a square cross section and a steel beam.

[Prior art]

Shaped steel column 1 having a square cross section and shaped steel beam 2 such as I-shaped steel are
As shown in FIG. 4, a horizontal stiffener 9 is attached to the joint of the shaped steel column 1, and the ends of the shaped steel beam 2 are butt-welded via the horizontal stiffener 9 to join them.

[Problems to be solved by the device]

In the past, joining of the shaped steel column 1 and the shaped steel beam 2 requires attachment of the horizontal stiffener 9 or welding, which increases the number of processing steps and the strength of the joined portion is insufficient. It was unstable. The present invention has been made to solve the above-mentioned problems, and the purpose thereof is to reduce the number of processing steps such as welding not required, and to improve the strength of the joint portion. To provide a joint structure.

[Means for Solving the Problems]

The present invention is a joint structure of a shaped steel column 1 and a shaped steel beam 2 having a square cross-section, and a flange 4a of an H-shaped auxiliary core 4 on each side of a web 3a of an H-shaped main core 3. To form a reinforcing body 5 having four flanges 3b and 4b on the outer circumference.
The flanges 3b and 4b of the reinforcing body 5 are respectively fixed to the four inner peripheral surfaces of the, and the end portions of the shaped steel column 1 and the shaped steel beam 2 to which the flanges 3b and 4b of the reinforcing body 5 are fixed are joined with the metal fitting 6. Bolt 7 through
The above problem is solved by this configuration. [Operation] Since welding is performed by the welding hardware 4, welding is not required,
The number of processing steps can be reduced, and since the reinforcing body 5 is attached inside the shaped steel column 1, the shaped steel column 1 is reinforced and the reinforcing metal 3 is attached to the shaped steel column portion 1a and the shaped steel. Since the end portion of the beam 2 is fixed by the bolt 7 via the metal joint 6, the joint strength is increased and the performance is stabilized. Example As shown in FIG. 3, the reinforcing member 5 is a web of H-shaped main core material 3.
The flange 4a of the H-shaped auxiliary core material 4 is fixed to both sides of 3a, and four-sided flanges 3b and 4b are formed on the outer periphery. A nut 8 is attached to the inner surfaces of the flanges 3b and 4b. The length between the flanges 3b and the length between the flanges 4b of the reinforcing body 5 are slightly smaller than the length between the inner surfaces of the shaped steel column 1 which face each other. The shaped steel column 1 has a square cross-section, and the reinforcing body 5 is inserted into the shaped steel column 1, and the flanges 3b and 4b of the reinforcing body 5 are inserted through the nuts 8 on the four inner peripheral surfaces at predetermined positions. Bolted together. A bolt 7 is fixed with a nut 8 of the flanges 3b and 4b through a joint metal 6 having a split T between the shaped steel column 1 portion to which the flanges 3b and 4b of the reinforcing body 5 are fixed and the end of the shaped steel beam 2 are split. ing. Flange 3 in this example
Nuts 8 in two rows in the vertical direction with a certain space on b and 4b.
Since it is attached, the shaped steel beam 2 can be eccentrically joined.

[Effect of device]

The present invention is a joint structure of a shaped steel column and a shaped steel beam having a square-shaped cross section. Since joining is performed with a joining metal, welding is not required, the processing man-hours can be reduced, and the reinforcing body is a shaped steel. Since it is attached inside the column, the shaped steel column is reinforced, and the end of the shaped steel column where the reinforcing metal is attached and the end of the shaped steel beam are bolted through the joining metal, so the joining strength is improved. It is large and stable in performance.
