Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an external component used for roofing or walling a building. The member of the present invention was originally developed as a roofing member, and the embodiment shown in B8 of this specification is also a roofing member, but it is also useful as a building wall member.

The outer surface forming member of the present invention is usually a press-molded product of a metal plate, but depending on the purpose or place of use, it can also be a molded product of a plastic material or a cast product of metal. In typical use, a plurality of members of the present invention are attached to a plurality of structural or support members in an overlapping arrangement to cover an area greater than the surface area of a single member of the present invention. A roof can be constructed by arranging a large number of outer surface constituent members of the present invention.

The traditional roofing material is ceramic straw.

There are many types, including concrete slabs, press-formed or roll-formed metal panels, wood tiles (shingles), fiberglass-reinforced plastic panels, and various composite panels. Structural members of roofs using these roofing members are subjected to not only the own weight of the roofing members, but also static loads due to snow accumulation, dynamic loads due to wind, earthquakes, etc. Such loads can create stresses within the structural and/or roofing members that can cause the roofing members to move away from the structural members. To address this problem, conventional roof construction typically attaches load-bearing support members such as batten and/or wood panels to the roof girdle structure, in which case the roofing members are Fix it to a support member such as a plate.

The exterior structural member of the present invention is designed to be able to be attached directly to roof rafters, trusses and/or crosspieces by inherently having a non-directional load-bearing capacity. By using this, the cost of procuring and installing battens, etc. for conventional purposes becomes unnecessary. Additionally, the use of this component may allow the omission of some of the bracing normally included in the roof framework.

The feature of the outer surface forming member of the present invention lies in its shape. This outer surface forming member has a quadrilateral slotted part, and a raised part having an inverted U-shaped cross section is formed integrally with the panel part along the upper side of the panel part. Therefore, the inner wall surface of this shaded part can be said to extend upward from the upper side of the tunnel part. - A plurality of lips are formed in the tunnel portion, extending from the inner wall surface of the raised portion toward the lower side of the panel. The inner wall surface of the raised portion has a concave portion facing each rib, and the end portion of the rib intrudes into the concave portion formed thereby. The lower side of the panel portion forms a downwardly projecting edge along its entire length.

This external surface component is intended to be used by being installed and fixed to at least two building structural members spaced apart. When erected and fixed in this way, the raised parts on the upper sides of the external components perform a reinforcing function similar to that of crossbars in conventional roof structures, and the panel parts play a load-bearing role and are similar to other types of roofing members. Similarly - acts as a seal against wind and rain.

This outer surface forming member is preferably made by molding a sheet-like material, most preferably a press-molded metal plate.

It is preferable to form three or more of the above-mentioned ribs on one outer surface forming member, and it is most preferable to form about 12 ribs.

When in use, one of the ribs of one of two laterally adjacent outer surface forming members is inserted under one of the ribs of the other member, so that they are fixed in a partially overlapping arrangement. Two vertically adjacent members are partially overlapped with each other so that the protruding edge of the lower side of the upper member rests on the raised portion of the upper side of the lower member.

Hereinafter, preferred embodiments of the present invention will be explained in more detail with reference to the drawings.

The outer surface construction member 10 shown in FIGS. 1 to 5 is a roofing member and has a rectangular panel portion 11.
