- the elastic adhesive can change its elastic modulus and curing time by changing its components and component ratios. Therefore, for example, when the difference between the thermal expansion coefficient of the flat panel 10 and the thermal expansion coefficient of the reinforcing panel 20 is large, or when the use temperatures are different from each other, an elastic adhesive having a lower elastic modulus may be used. Moreover, when shortening manufacturing time, it is good to use an elastic adhesive with a short hardening time. Further, in the case where the difference between the thermal expansion coefficient of the flat panel 10 and the thermal expansion coefficient of the reinforcing panel 20 is large and it is desired to shorten the manufacturing time, as shown in FIG.
- a plurality of first parietal portions 25s having one or more parietal portions 25t interposed between them are arranged with an elastic adhesive having a short curing time, and between the plurality of first parietal portions 25s. It is preferable to arrange an elastic adhesive having a long curing time on the second top 25t interposed between the two.
- an elastic adhesive having a long curing time As described above, by using two types of elastic adhesives having different curing times, the distance between the reinforcing panel 20 and the flat panel 10 is maintained by the cured adhesive when the adhesive having a short curing time is cured. Therefore, the force applied in the direction in which both approach between the reinforcing panel 20 and the flat panel 10 at this time can be released. Therefore, the manufacturing time can be shortened.
- the curing time may be a time for the adhesive 5 to be completely cured, or may be a time until the adhesive 5 reaches a practical strength.
- the curing time of the adhesive can be shortened by changing its components and component ratios.
- the adhesive is a moisture curing type, it is also possible to manage the humidity in the application environment of the adhesive. It can be shortened.

本願は、2012年3月28日に、日本に出願された特願2012-074948号に基づき優先権を主張し、その内容をここに援用する。
ところで、平パネルと補強パネルとの接合方法としては溶接が考えられる。溶接による接合方法は、パネル相互の接合強度が高いものの、溶接による不要な変形が伴う上に、各パネルが金属である必要がある。
しかも、補強パネル側で平パネルと接合される部分には、所定の面積が確保されているため、ここに接着媒体を配することで、パネル相互間における高い接合強度を確保することができる。さらに、上記態様に係るパネル構造体では、平パネルと補強パネルとの接合に接着媒体を用いているため、溶接接合した場合における接合部周りの熱変形を回避することができる。
本実施形態のパネル構造体1は、図1に示すように、板状の平パネル10と、この平パネル10に接合される補強パネル20と、を備えている。
本実施形態のパネル構造体1aは、図6及び図7に示すように、板状の平パネル10と、この平パネル10に接合される補強パネル20と、補強パネル20の背面(平パネル10と反対側の面)に接合される複数の支持梁30と、を備えている。
