[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a so-called rooftop projecting from outer walls intersecting at right angles,
The present invention relates to a handrail wall support structure that facilitates the formation of a handrail wall on the outer edge of a rooftop portion such as a balcony.

[Conventional technology]

In recent years, the panel construction method, in which walls, roofs, floors, etc. are formed using panels, has been widely used, and in such buildings, houses with the same specifications are constructed so that residents can choose according to their preferences. Also, multiple types of houses with different external appearances etc. are standardized and prepared.

On the other hand, with the diversification of residents' preferences in recent years, for example,
As shown in the figure, a one-story house attachment part B is provided on a multi-story house main body part A, and a rooftop C includes an overhanging part extending outward from wall panels P1 and P2 that intersect at right angles to the house attachment part B. may form. In addition, in multi-story houses, balconies may be formed extending from the right-angled outer walls.

Rooftop areas such as this rooftop C1 balcony,
There are cases where it falls outside the scope of the standardized housing mentioned above.

[Problem to be solved by the invention]

Therefore, in the past, in order to form such roof sections according to residents' requests, new parts were designed and manufactured each time, which resulted in poor work efficiency and increased construction costs. was.

The present invention uses corner metal fittings and connecting metal fittings, and standardizes the handrail wall having the lattice beam portion in advance, thereby streamlining construction work on the rooftop area and helping to reduce costs. The purpose of the present invention is to provide a handrail wall support structure that allows for diversification of the range of choices for houses according to the tastes of people.

[Means to solve the problem]

The present invention provides a handrail wall support structure for a rooftop portion that extends along two wall panels that intersect at right angles and from the upper ends of the wall panels, and that provides a handrail wall on the outer edge, the handrail wall having a top chord, a bottom chord, and a handrail wall. It consists of a handrail panel with a handrail integrally provided on the upper surface of a lattice beam part in which a lattice is provided between the materials, and at the upper end of the intersection of the wall panels, the floor of the roof part protrudes from the base frame perpendicularly to the wall panels. Fix the base frame of the corner fitting provided with two cantilever beams for receiving the handrail wall, and connect the handrail wall so that the lattice beam portion of the handrail wall is connected to the tip of the cantilever beam and to the two wall panels, respectively. The handrail walls are arranged in parallel and intersected by bolts, and connecting fittings are provided at the intersections of the handrail walls to connect the handrail walls by bolting them to the lattice beams of the handrail walls, respectively. This is a handrail wall support structure.

[Effect]

The handrail wall uses a handrail panel in which a handrail part is integrally provided on the upper surface of a lattice beam part in which a lattice is provided between the upper and lower chord members.

Thereby, a handrail can be formed by passing the frame, and compared to the case where this handrail is attached later, the construction strength is increased, and by integrally providing the lattice beam part, a strong handrail can be formed.

Further, by fixing a corner fitting having a cantilever to the orthogonal part of the wall panel, attaching the handrail wall at the tip of the cantilever, and connecting the intersection of the handrail walls using a connecting fitting,
A rooftop portion can be formed that extends from the intersection of the wall panels. Furthermore, by standardizing such corner fittings, connecting fittings, handrail walls, etc. in advance, the rooftop section can be easily formed, and by diversifying houses, a range of houses can be selected according to the tastes of residents. It will spread.

〔Effect of the invention〕

In this way, the handrail wall support structure of the present invention can be used as a handrail wall.
Since a handrail panel is used in which a handrail part is integrally provided on the top surface of a lattice beam part with a lattice between the upper and lower chord members, the construction work is more convenient than when the handrail is added later, and the lattice beam part is provided. This allows a strong handrail to be formed.

In addition, the handrail wall is attached at the tip of the cantilever of the corner fitting fixed to the upper end of the intersection of the downstairs wall panel P, and in addition, since the intersection of the handrail wall is connected using a connecting fitting, there is no tension from the wall panel. It is possible to easily form an eave-like roof part. In addition, by preparing such corner fittings, connecting fittings, and handrail walls in advance, the formation of the rooftop portion is facilitated, and
It becomes possible to form a variety of houses that meet the preferences of residents.
