However, in the case of a show window, it is necessary to reinforce by increasing the cross section of the frame member and the exterior panel as the window area increases, so that both weight and cost increase. However, there is a problem that not only the cross section of each member such as the frame member becomes large and the appearance becomes unsightly, but also the window area is narrowed.

Also, in the case of a curtain wall, as the wall area increases, the cross section of the upright and the eye-less material increases, which causes the above-mentioned problems.

The present invention has been made in order to solve the above-mentioned problems. In particular, FRP materials having various characteristics such as transparency, semitransparency, fire resistance, high heat insulation, high strength, super light weight, and flexible molding depending on the composition. It is an object of the present invention to provide a building exterior structure capable of providing a show window or the like suitable for a living environment required for a building's usage such as high heat insulation performance and energy saving by using the frame material and the exterior panel.

[0007]

An exterior structure of a building according to claim 1 comprises a frame and an exterior panel attached to the frame as a wall panel and a window panel, respectively. The frame and the exterior panel are made of FRP material. It is characterized by being formed.

The present invention is particularly applicable to a frame and a wall panel made of an FRP material having various characteristics such as transparency, translucency, fire resistance, high heat insulation, high strength, super light weight, and flexible molding depending on the composition.
Show windows, curtain walls, roofs, top lights, etc. that are suitable for the living environment required for building applications, such as high insulation performance and energy saving, by utilizing the characteristics of FRP materials by using the exterior panel that is installed as a window panel Can be built.

For example, the frame is made of a fire-resistant and high-strength FRP material, and the frame is made of transparent / translucent and highly heat-insulating FRP material.
By attaching an exterior panel made of material as a window panel, it is possible to form a window having excellent fire resistance, high strength, and high heat insulation performance. Further, by using the exterior panel made of a highly deformable FRP material as the window panel, a dome-shaped top light can be easily formed.

The building exterior structure according to a second aspect is the building exterior structure according to the first aspect, wherein the frame has a plurality of vertical shafts each having a hollow base portion and projecting portions projecting from side portions of the base portion. It is characterized in that it is formed in a lattice shape from a supporting material and a horizontal receiving material.

The exterior structure of a building according to a third aspect is the exterior structure of a building according to the first or second aspect, characterized in that the frame and the exterior panel are heat-welded. Since the framework and the exterior panel are heat-welded, the joint portion between the framework and the exterior panel can be integrated.

The horizontal receiving members 2 are horizontally laid across the middle portion.

The wall panel 3 is fitted into the upper end of the frame A thus framed, the window panels 4 are fitted into the middle and lower ends thereof, and they are fixed by the ridge members 5 and 6, respectively. .

The vertical support member 1 is formed of a base portion 1a formed in a hollow circular cross-section and a projection portion 1b continuously protruding in the vertical direction on the outdoor side portion of the base portion 1a. Part 1
An engaging groove 1c is formed continuously at the tip of b in the vertical direction of the protruding portion 1b.

Similar to the vertical support member 1, the horizontal support member 2 has a base 2a formed in a hollow circular cross-section and a projection 2b continuously protruding laterally from the outdoor side of the base 2a. And the engaging groove 2c is formed at the tip of the protrusion 2b.
Are continuously formed in the horizontal direction.

Further, both the vertical supporting member 1 and the horizontal receiving member 2 are made of FRP material, especially fireproof FRP material. As the FRP material in this case, for example, a phenol FRP material can be used.

The wall panel 3 is formed of a fireproof FRP panel, and the window panel 4 is formed of a semitransparent GW-containing FRP panel or a transparent FRP panel. The transparent FRP panel in this case is made of, for example, acrylic or polycarbonate.

The ridge member 5 includes a web portion 5a and a flange portion 5
b has a substantially T-shaped cross section, and the ridge member 6 has a substantially T-shaped cross section from the web portion 6a and the flange portion 6b. In particular, the flange portion 6b of the ledge member 6 has a substantially arc-shaped cross section. . Further, both the ridge members 5 and 6 are made of a fire-resistant FRP material like the vertical support member 1 and the horizontal support member 2.

In this case, the pushing edge member 5 is fixed to the protruding portion 1b of the vertical support member 1 by inserting the web portion 5a into the engaging groove 1c formed at the tip of the protruding portion 1b, and the pushing edge member 6 is moved to the web portion 6a. An engaging groove 2c formed at the tip of the protrusion 2b
It is fixed to the projecting portion 2b of the lateral support member 2 by being inserted into.

The flange portion 5b of the ledge member 5 and the base portion 1a of the vertical support member 1 sandwich the side edge portions of the wall panel 3 and the window panel 4, respectively, and the flange portion 6b of the ledge member 6 and the lateral support member. The upper and lower edge portions of the wall panel 3 and the window panel 4 are respectively sandwiched by the two base portions 2a.

Further, the peripheral portions of the wall panels 3 and the window panels 4 are heat-welded to the vertical support member 1, the lateral support member 2, the pushing edge member 5 and the pushing edge member 6, respectively. In this case, the peripheral portions of each wall panel 3 and the window panel 4 are the protrusions 1 of the vertical support member 1.
