However, the structures shown in FIGS. 11A and 11B are not suitable when the weir wall 3 is made of lightweight foamed concrete.

On the other hand, although cylindrical supports 2 are shown in the embodiments, other cylindrical supports such as square pipes may also be used.

Further, the pressure receiving rib 16 fixed to the inner lower surface of the connection metal frame 14 is not necessary if there is no problem in terms of strength.
On the other hand, if further increase in strength is required, various changes can be made, such as making it box-shaped with an open bottom surface.

Moreover, the shape of the rotation-preventing seat plate 7 may be made into a different shape as desired, such as a simple flat plate shape.

As described above in detail, the handrail mounting device according to the present invention has a post insertion hole provided at the bottom of the cap of the square pipe-shaped handrail, and a detent seat plate is placed over the insertion hole inside the cap. The upper end of the coupling bolt, which is inserted into the Kasagi through the insertion hole and passed through the nut portion of the seat plate, is brought into contact with the upper part of the inner surface of the Kasagi, and the seat plate is pressed against the lower part of the inner surface to connect the Kasagi and the coupling bolt. Since the cylindrical support is fixed to the outside of the connecting bolt and its upper end is inserted into the insertion hole, the connecting member between the cap and the support is not visible from the outside and the appearance is good. The upper end of the support is located inside the Kasagi, making it difficult for rainwater etc. to enter the support, and there is no fear that the support will shift or come off.

In addition, the lower end of the connecting bolt is made to penetrate and protrude through the saddle-shaped connecting metal frame that is connected to the weir wall capping cap and its internal lower surface,
Each member is integrated by tightening nuts from this protruding end, and the saddle-shaped connecting metal frame is fitted over the mounting metal frame which is fixed to the top of the weir wall via an anchor fitting to connect both. Since it is fixed, there is no need for space around the outer periphery of the handrail as in the past, making it possible to maximize the usable space on balconies and rooftops. The installation and installation can be done at the same time, greatly reducing the amount of work required compared to conventional methods.

In addition, each part is unitized, making it extremely easy to assemble and install the handrail, and it is also excellent in terms of mass production and transportability.

Furthermore, in a configuration in which a support rod is provided, the base of the support rod is reinforced from within, increasing the strength of the handrail in the direction of inclination.
