BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stair handrail mounting structure, and more particularly to a technique for appropriately and efficiently mounting a handrail pipe to a vertical wall portion on a side of a stair in a framed frame construction house.

[0002]

2. Description of the Related Art As is well known, in prefabricated houses and the like in recent years, a framed frame method has been implemented. One example of this type of method is that a skeleton is previously formed using a steel frame or the like. Assemble the frame, and then
By attaching a panel material such as an outer wall panel to the frame frame, a wall of the building is constructed. Therefore, when a stair is constructed based on this kind of construction method, a vertical wall portion (building main body wall or stair sleeve wall) existing on the side of the stair is formed by attaching an outer wall panel to a framed frame. You. And, in consideration of the safety of pedestrians who go up and down the stairs, it is customary that a handrail is attached to the vertical wall in an inclined manner.

[0003]

By the way, the above handrails are provided so as to protrude from the vertical wall toward the stairs. However, if the handrails are directly attached to the outer wall panel,
The strength becomes insufficient, and it cannot be used at all. Therefore, it is necessary to attach this handrail directly to the frame assembly frame, but if you try to attach the outer wall panel after attaching this handrail to the frame assembly frame, the handrail will be in the way and the attaching work will be difficult. It becomes extremely difficult and troublesome.

[0004] The present invention has been made in view of the above-mentioned circumstances, and the handrail portion protruding and attached to the vertical wall portion is appropriately made into parts, and the configuration of each part is optimized, so that the handrail is provided. An object of the present invention is not only to sufficiently secure the strength of the portion, but also to improve the workability or workability of a panel material such as an outer wall panel.

[0005]

SUMMARY OF THE INVENTION The stair handrail mounting structure according to the present invention, which has been made to achieve the above technical object, has the following features. That is, it has a base buried in the vertical wall portion present on the side of the stairs and fixed to the frame frame, has a protrusion protruding from the vertical wall to the stairs side, and engages with the tip of the protrusion. An attachment plate having a mating portion, and a handrail stay having an engagement body detachably engaged with and held by the engagement receiving portion of the attachment plate and having a tubular body fixed above the engagement body. The handrail pipe is fitted and held in the cylindrical body of the handrail stay.

[0006]

According to the above means, when attaching the handrail pipe to the vertical wall on the side of the stairs, first, the base of the mounting plate is fixed to the frame assembly forming the framework of the vertical wall with bolts or the like. Thereafter, a panel material such as an outer wall panel is attached to the frame frame. In this case, although the mounting plate protrudes toward the stairs, only the engagement receiving portion is formed at the tip thereof. As a result, only a minimum number of obstacles are obstructed during the operation of attaching the panel material, and the operation can be performed extremely easily. And
After the work of attaching the panel material is completed, the engagement body of the handrail stay is engaged with the engagement receiving portion of the mounting plate, and then the handrail pipe is fitted into the tubular body of the handrail stay to perform connection. Then, the respective parts are fixed with screws or the like, and the mounting work of the stair railing is completed.

In the above configuration, the mounting plate and the handrail stay are formed as separate components because the cylindrical body of the handrail stay has a relatively large size because the handrail pipe is fitted therein. If the mounting plate and the handrail stay are integrated, the cylindrical body of the handrail stay becomes an obstacle when the panel material is adhered, and the workability is deteriorated.
