Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a panel type handrail structure that is installed upright on the outer side of the floor frame in a steel-framed outdoor stairway unit or the like.

(Prior Art and its Problems) When a handrail is provided on the outer side of a floor frame for a landing, a floor frame for a hallway, etc. in an outdoor staircase unit as described above, conventionally, a plurality of handrail supports are attached to the floor frame. There is a method in which the handrail side wall panels are installed on the floor close to the outside edge of the frame, or are installed so that the lower end side of the support is attached to the outside of the floor frame, and the handrail side wall panel is installed between the support supports. It had been taken.

The former method of erecting the pillars on the floor not only makes the floor space narrower, but also reduces the installation strength of the pillars.
As a result, it becomes difficult to sufficiently increase the strength of the handrail as a whole. In addition, in the latter method of attaching the support to the outside of the floor frame, the strength of the support can be increased, but when looking up at the handrail from below, the appearance of the outside of the floor frame becomes poor, and the distance between the floor and the handrail increases. It also has the disadvantage of creating a gap between it and the side wall panel.

(Means for solving the problems) The present invention proposes a handrail structure that can solve these conventional problems, and its features are as follows:
Supports are erected at appropriate intervals from the outside of the floor frame, a cap is placed between the upper ends of the supports, a lower crosspiece is placed between the lower ends, and the floor surface on the floor frame is placed between the middle parts. erect gap covering materials that are continuous and substantially flush with each other, and screw the side wall panels with their upper sides to the caps, their lower sides to the lower crosspieces, and both left and right sides to the pillars. The lower crosspiece is further provided with an exterior cover material that covers the lower side of the lower crosspiece.

(Example) An example of the present invention will be described below based on the attached illustrative drawings.
