クリート充填も困難であるという欠点を有している。[Prior Art] The joint (also called the joint part) between a square steel pipe concrete column and a steel beam, in which concrete is filled inside the steel pipe, is used to reliably transmit stress such as shear force and moment from the beam to the column. Generally, an outer diaphragm or an inner diaphragm is attached in the cross-sectional direction of the column side at the joint between the column and the beam flange. FIG. 3 shows an example of the outer diaphragm type joint, and FIG. 4 shows an example of the inner diaphragm type joint. 1 is a square steel pipe column, 2 is a steel beam, 3 is an outer diaphragm, and 3' is an inner diaphragm. Normally, the steel pipe column is filled with concrete as soon as construction is completed at the site. By the way, the outer diaphragm shown in Fig. 3 has a fundamental weakness in that the flange protrudes greatly at the joint, making it difficult to fit in the design, and is not preferred by designers, while the inner diaphragm shown in Fig. 4 is expensive to manufacture. Another disadvantage is that it is difficult to fill the inside of the column with concrete.

By attaching the beam to the column, stress concentration at the joint between the beam and the column can be alleviated and stress transmission can be ensured.

(also called skin plates) are assembled into a box shape on four sides.The steel plate 11 that constitutes the general part and the steel plate 12 that constitutes the column material at the column-beam joint have different plate thicknesses, and the The joint part uses a thicker plate than the general part, and the diaphragm is omitted. On the other hand, the beam 2 connected to this column is an H-beam steel whose flanges are oriented vertically and horizontally, and the upper and lower flanges 21, 21, and web 22 are each welded to the skin plate 12 of the thick part of the column material by the usual method. ing.

As seen in FIG. 1, since the column side of the cover plate overlaps the beam flange, the previously welded plate can serve as a backing metal for later welding. As shown in Figure 2, the shape of the cover plate 23 is such that the column side is close to the width of the column, the welding line is made as long as possible, and the angle α shown in the figure is 30 to 30 degrees in order to save material and alleviate stress concentration. About 45 degrees is good.

Since there is no external diaphragm, there are no design restrictions, and by attaching the cover plate stress concentration at the column attachment part at the end of the beam is alleviated, and stress transmission is ensured.
