Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exterior panel constituting a roof or an outer wall of a building, for example, for covering a building or a bus stop, and more particularly to an exterior panel formed by bonding a plurality of extruded members made of an aluminum alloy. About the panel.

[0002]

2. Description of the Related Art In general, extruded profiles of aluminum alloys are widely used as exterior materials for buildings because their sectional shapes can be freely designed. For example, a method of fixing a plurality of extruded members to a support member of a building by screws or the like in a state where a plurality of extruded members are fitted to each other at respective ends, such as a spandrel or siding of an outer wall, has been widely adopted. However, almost any method of screwing any one of a plurality of extruded profiles to the above-mentioned support member first, and then fitting the extruded profiles to each other at a fitting portion to form a continuous spandrel or the like is used. Must be done on site. For this reason, there has been a problem that on-site construction costs are high.

In order to solve the above-mentioned problem, the inventors are studying an exterior panel in which a plurality of extruded members are integrally joined in advance with an adhesive. It has been confirmed that the above-mentioned adhesive does not cause a problem in strength due to aging, and is being used in the field of construction. However, it is considered that it is extremely difficult to completely prevent cracks that partially occur in the adhesive. On the other hand, with the modernization of urban landscapes, the roofing materials for bus stops and the like are required to be more durable, have a more flexible design, and have shorter on-site construction work, from simple designs made of bent steel plates and tent sheets. Have been. For such a roofing material, for example, it is conceivable to use an exterior panel in which the plurality of extruded shapes are integrally joined in advance with an adhesive. However, in the case of a roofing material into which rainwater can always enter, it is essential to prevent water leakage, and it is necessary to take measures against the cracks of the adhesive. On the other hand, honeycomb sandwich panels have been used in recent years for the above applications, but the structure and manufacturing costs are increased, and the joints between the panels are filled with silicon caulking on site, which increases the number of construction steps. And the cost must be high.

[0004]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems in the prior art, enables easy on-site construction, can be constructed in a short period of time, reliably prevents rainwater leakage, and has an external design. Another object of the present invention is to provide an exterior panel that can be freely formed.

[0005]

According to the present invention, in order to solve the above-mentioned problems, the fitting portions at the ends of a plurality of extruded profiles are joined together by bonding with an adhesive, and the fitting portions are joined together. It is made with the idea of arranging a packing or a gutter between them. That is, the first exterior panel of the present invention is an exterior panel in which a plurality of extruded profiles made of an aluminum alloy are fitted with fitting portions formed at ends of flat cross sections in a direction orthogonal to the extrusion direction. Wherein the fitting portions of the profile are bonded with an adhesive, and the fitting portions are in close contact with the fitting portions at least closer to the outside than the position of the adhesive. It is equipped with packing.

In the second exterior panel of the present invention, a plurality of extruded profiles made of an aluminum alloy are fitted by fitting portions formed at ends of flat cross sections in a direction perpendicular to the extrusion direction. In the exterior panel, and between the fitting portions of the profile is bonded with an adhesive, and a gutter portion is formed between the fitting portions at a position closer to the interior than the position of the adhesive, It is characterized by the following. Furthermore, a third exterior panel of the present invention is an exterior panel in which a plurality of extruded members made of an aluminum alloy are fitted with fitting portions formed at ends of flat cross sections in a direction orthogonal to the extrusion direction. Wherein the fitting portions of the profile are bonded with an adhesive, and the fitting portions are in close contact with the fitting portions at least closer to the outdoors than the position of the adhesive between the fitting portions. The present invention is characterized in that a packing is attached and a gutter piece is formed at a position closer to the indoor side than the position of the adhesive.

[0007] According to these, an exterior panel having a relatively large span composed of a plurality of extruded profiles can be integrally formed while maintaining the required adhesive strength, and can be easily and quickly performed on site, and is inexpensive. Can be provided. Also,
Even if the adhesive partially deteriorates due to aging and cracks occur, and rainwater permeates from this, the packing and / or gutter can surely prevent water leakage to the indoor side. Therefore, of course, when used for the outer wall,
Even if it is a roofing material directly supported by structural materials, such as a roofing material of a platform in a bus stop or a station yard, it can exhibit waterproofness. In addition, by changing the cross-sectional shape of the extruded shape, any design such as a gable roof or a Y-shaped roof can be freely provided in addition to the single-flow roof.

Further, each fitting portion of the plurality of extruded profiles is
An exterior panel, which is a male fitting portion and a female fitting portion fitted to each other, is also included. According to this, it is possible to easily and accurately fit the adjacent profile members together, and to fill the adhesive applied between them with less leakage to the outside, and to easily maintain the adhesive strength at the initial high level. Is also possible. Further, each of the fitting portions of the plurality of extruded profiles includes a male fitting portion and a female fitting portion fitted to each other, and at least an outdoor position is closer to the position of the adhesive in the female fitting portion. An exterior panel is also included in which the base of the packing, which is in close contact with the male fitting portion that fits with the female fitting portion, is held at the position. Thus, the packing can be easily attached to the flange or the like of the female fitting portion that receives the male fitting portion located on the outdoor side or the indoor side, and the adhesive can be protected. The packing may be mounted on both the outdoor side and the indoor side of the female fitting portion, or may be mounted only on the outdoor side.

Further, each of the fitting portions of the plurality of extruded profiles comprises a male fitting portion and a female fitting portion fitted to each other, and the position of the adhesive in the female fitting portion is larger than the position of the adhesive in the female fitting portion. An exterior panel provided with the gutter portion at a position closer to the indoor side facing and approaching the male fitting portion fitted with the female fitting portion is also included. According to this, the gutter portion can be easily formed in the portion of the female fitting portion located on the indoor side, and the gutter portion is opposed to and close to the male fitting portion of the adjacent shape member. Even if the rainwater permeates from cracks generated in the adhesive, it can be reliably discharged to the outside along the gutter portion without leaking to the indoor side. It is desirable to provide a step portion having substantially the same width dimension as the gutter portion at the portion of the male fitting portion which is opposed to and close to the gutter portion in order to ensure the drainage function by the gutter piece.

[0010] The present invention also includes an exterior panel in which the male fitting portion has a drainage projection located above the gutter portion provided on the female fitting portion fitted with the male fitting portion. According to this, even if rainwater infiltrates from cracks in the adhesive, it can be reliably and easily guided into the gutter,
It is more reliable to prevent water leakage to the indoor side. Further, fitting portions formed at the end portions of the extruded profile are formed at two positions inside and outside in the thickness direction in a flat cross section orthogonal to the extrusion direction, and between these fitting portions. And an outer panel in which the gutter portion is disposed between the two inner and outer fitting portions.

According to the above exterior panel, even if rainwater cracks in the adhesive on the outdoor side and permeates between the fitting portions,
Water can be collected and drained reliably by the gutters located between them, and the adhesive on the indoor side can be protected. Therefore, it is possible to reliably prevent leakage of water indoors over a long period of time. In addition, the gutter portion having a relatively large cross section can be formed, and the fitting portions bonded to the outdoor / indoor side are formed, so that the strength against the bending moment in the indoor / outdoor direction can be increased. In addition, the present invention also includes an exterior panel in which a gap is formed between the male fitting portion and the female fitting portion to receive an excess of the adhesive. According to this, an adhesive having an appropriate thickness is applied between the fitting portions, so that the required adhesive strength can be exhibited, and even if an excessive amount of adhesive is applied due to dispersion of the application operation, the adhesive is absorbed in the gap. Therefore, it is also possible to prevent a situation in which the space between the fitting portions is exposed to the outside.
