転自在に連結した構成である。In such a mountain retaining method, it is necessary to support the uprising 1 by using a beam 7 or a whipping, and a joint for connecting the uprising 1 and the beam 7 has been conventionally used, for example. There are those shown in FIGS. 14 and 15. That is, on the plate 20 on the abdomen side, the shaft 2 orthogonal to the surface of the plate 20 is provided.
A rotary plate 22 that is rotatable around one turn is connected to a bracket 23 that is vertically installed on the rotary plate 22. A bracket 25 that is vertically installed from a joint beam-side joint plate 24 is orthogonal to the brackets 23 and 25. It is configured to be rotatably connected around the horizontal axis 26.

There is a joint shown in. This is formed by forming a female member 32 on the uprising side having a hemispherical seat 31 in the center of the plate-shaped base 30 and a spherical pivot 34 in the center of the plate-shaped base 33, and forming it on the side of the oblique beam 7 '. It is a joint including a male member 35 to be provided, and a ball joint having a configuration in which the pivot 34 provided to the male member 35 is fitted to the hemispherical seat 31 of the female member 32.

In addition, in the conventional joint shown in FIG. 15, the plate 20 on the uprising side and the joint plate 24 on the girder side rotate in the vertical direction (paper surface direction) about the horizontal shaft 26.
The rotary plate 22 is rotated and displaced around the shaft 21 orthogonal to the horizontal shaft 26 with respect to the plate 20 on the uprising side. Therefore, this joint has a disadvantage that the joint plate 24 on the girder side is lacking in the horizontal rotation with respect to the plate 20 on the rising side. Therefore, there is a disadvantage that beams and flint cannot be supported on the mountain retaining wall at different installation angles depending on the site.

When this joint is fixed to the slanted beam 7'as a set, no matter what the installation angle of the slanted beam 7'with respect to the uprising 1, there is an advantage that the degree of freedom of the joint can be sufficiently exerted. The male member 35 is apt to rotate carelessly with respect to the female member 32, and the slanted beam 7 ′ is erected with respect to the plate-shaped base 30 on the 1st side.
There is an inconvenience that the plate-shaped base 33 on the side cannot be set and fixed at a fixed position.
