JPH055324A - Joint between steel frame square column and beam - Google Patents

Abstract

PURPOSE:To constitute the outer diaphragm of a steel frame square column without cutting a column, to be applicable to a steel frame square column having any size, and to cope with a slight difference in a step between steel frame beams crossing each other at right angles. CONSTITUTION:A pair of upper and lower joining metals 1 respectively crossing a column surface at right angles are attached to the corner part of a steel frame square column A in which a flange 3 of a steel frame beam B ties. A regulating plate 2 is located between joining metals 1 and 1 horizontally adjacent to each other, and the flange 3 of the steel frame beam B is welded and joined to the regulating plate 2 and the joining metals 1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint between a steel prism and a steel beam.

[0002]

2. Description of the Related Art The joint portion between a steel-framed steel pipe column and a steel-framed beam is usually cut from a steel pipe to form a diaphragm connection.

[0003]

In the above-mentioned conventional joint structure, the cutting work of the column is required, and the construction requires a lot of labor and time, and it is easy to deal with the case where there is a step between the beams orthogonal to the column. Not. The present invention has been proposed in view of the above problems of the prior art, the object of the present invention, the diaphragm processing is performed without cutting the column, can be applied to steel prisms of any size, orthogonal steel frame The point is to provide a joint between the steel prism and the beam, which can correspond to some steps of the beam.

[0004]

In order to achieve the above-mentioned object, the joint portion between the steel prism and the beam according to the present invention is orthogonal to the corner face of the steel prism where the flange of the steel beam engages. A pair of upper and lower jointed metal fittings are mounted, an adjustment plate is interposed between the adjacent jointed metal fittings in the horizontal direction, and a flange of a steel beam is welded and joined to the adjustment plate and the jointed metal fitting.

[0005]

According to the present invention, without cutting the steel prism,
By attaching a pair of upper and lower joining metal fittings orthogonal to the pillar surface to the corner portions of the same pillar and interposing an adjusting plate between the horizontally adjacent joining metal fittings, without cutting the steel frame pillar. The diaphragm can be configured.

Then, the flange of the steel frame beam is welded to the joint metal and the adjusting plate to join the steel frame beam and the steel prism. At this time, some steps of the orthogonal steel frame beams correspond to each other by utilizing the thickness of the flange of the metal joint.

[0007]

The present invention will be described below with reference to the illustrated embodiments. A is a steel prism, to the corner of which is welded a casting metal fitting 1 having an inverted T-shaped cross section of an L-shaped upper and lower, which is located across two adjacent surfaces that are orthogonal to each other with a ridge line in between. A flat steel adjusting plate 2 matching the size of the steel prism A is interposed between the adjacent metal fittings 1 and 1, thus forming an outer diaphragm without cutting the prism.

B is a steel frame beam, and the upper and lower flanges 3 are welded and joined to the joint metal fitting 1 and the adjustment plate 2 by a steel frame prism A.
And the steel beam B are connected. The outside of the steel prism A and the web of the steel beam B are joined by a conventional method. Since the illustrated embodiment is configured as described above, when there is some level difference in the orthogonal steel beam B, the flange thickness of the joint metal 1 can be used. In addition, the shape of the jointed metal 1 is simple and applied to steel prisms of all sizes, the diaphragm can be easily attached to existing buildings or post-fabrication pillars, and it is applicable not only to factory machining but also on-site machining. ..

[0009]

EFFECTS OF THE INVENTION According to the present invention, it is possible to easily join a steel prism and a steel beam without cutting the steel prism, and the invention is applied to a joint between a steel prism and a steel beam of any size, The outer diaphragm can be easily attached to the existing building or the post-fabrication pillar, and thus can be easily added.

Further, according to the present invention, the slight difference in level of the orthogonal steel frame beams can be dealt with by utilizing the thickness of the flange of the joining metal object. Furthermore, the present invention is not limited to factory machining, but on-site machining. It can also correspond to.
