Description

Description: BACKGROUND OF THE INVENTION The present invention relates to a handrail wall support structure which facilitates the formation of a handrail wall provided on an outer edge of a roof portion such as a roof or a balcony extending from an outer wall which intersects at right angles. .

[Conventional technology]

In recent years, buildings of the panel construction method, in which walls, roofs, floors, etc. are formed using panels, are frequently used, and such buildings, so that residents can select according to their preference, even in houses of the same specifications. A plurality of types of houses having different appearances are standardized and prepared.

On the other hand, along with the recent diversification of occupants' preferences, for example, as shown in FIG. 1, a one-story house attachment part B is provided in a multi-story house body part A, and at right angles to the house attachment part B. There is a case where a rooftop C including a portion that extends outside from the intersecting wall panels P1 and P2 is formed. Also, in a multi-storey house, a balcony extending from a right outer wall may be formed.

Rooftop D such as rooftop C or balcony
May fall outside the range of the standardized house described above.

[Problems to be solved by the invention]

Therefore, conventionally, in order to form such a roof portion D in response to a resident's request, a new member is designed and manufactured each time, and thus, the work efficiency is poor.
Construction costs were increasing.

The present invention uses corner fittings and connecting fittings,
By pre-standardizing the handrail wall with lattice beams, it is possible to streamline the construction work on the roof and reduce costs, and diversify the selection range of houses according to residents' preferences. The purpose of the present invention is to provide a handrail wall support structure that can be used.

[Means for solving the problem]

The present invention is a handrail wall support structure for a rooftop portion along two wall panels that intersect at right angles and projecting from the upper end of the wall panel and having a handrail wall on an outer edge thereof, wherein the handrail wall includes:
Upper chord material, a handrail panel integrally provided with a handrail wall on the upper surface of a lattice beam portion providing a lattice between lower chord materials, and protruding from a base frame at right angles to the wall panel at the intersection upper end of the wall panel. The base frame of the corner fitting provided with two cantilever beams for receiving the floor of the roof portion is fixed, and the handrail wall is provided with the lattice beam portion of the handrail wall at the tip of the cantilever beam and the two handrails. A connection in which the handrails are bolted to each other by arranging them in parallel with the wall panel, and the handrail walls are connected to the intersections of the handrail walls by bolting to the lattice beams of the handrail walls. This is a handrail wall support structure provided with metal fittings.

[Action]

As the handrail wall, a handrail panel having a handrail portion integrally provided on the upper surface of a lattice beam portion having a lattice provided between the upper chord material and the lower chord material is used. Thereby, a handrail can be formed by bridging, and compared to the case where this handrail is retrofitted, the construction work can be enhanced, and a strong handrail can be formed by integrally providing the lattice beam portion.

Also, a corner fitting having a cantilever is fixed to the orthogonal portion of the wall panel, and the handrail wall is attached at the end of the cantilever and the intersection of the handrail wall is connected using a connecting fitting, thereby forming the wall. A roof portion that extends from the intersection of the panels can be formed. Also, by standardizing such corner fittings, connecting fittings, handrail walls, and the like in advance, the roof portion can be easily formed, and by diversifying the houses, the selection range of the houses according to the occupants' preference can be increased. It will spread.
