Abstract
A mirror (31) that reflects solar light, a rear plate (35) that supports a rear surface of the mirror (31), and a support frame (36) that is disposed on a rear surface of the rear plate (35) are prepared. Next, the rear plate (35) and the support frame (36) are joined to each other. Moreover, an adhesive agent is disposed between the mirror (31) and the rear plate (35), the mirror (31), the rear plate (35), and the support frame (36) are elastically deformed so that a reflecting surface of the mirror (31) forms a target three-dimensional curved surface, using a lower mold (51) and an upper mold (52), and the elastically deformed state is maintained until the adhesive agent is cured.

A method for manufacturing a mirror structure that comprises plate-shaped first and second mirrors each having a reflecting surface which reflects solar light and forms one rotation symmetry surface, a plate-shaped first rear plate which supports a rear surface of the plate-shaped first mirror, a plate-shaped second rear plate which supports a rear surface of the plate-shaped second mirror, and a support frame which is disposed on rear surfaces of the plate-shaped first and second rear plates, the mirror structure that radiates the solar light to a heat receiver using the reflecting surfaces of the plate-shaped first and second mirrors, the method comprising:
- a joining step of joining the plate-shaped first and second rear plates and the support frame;
- and
- an adherence step of disposing an adhesive agent between the plate-shaped first and second mirrors and the plate-shaped first and second rear plates, of pressing a first mold which contacts the first and second mirrors to a second mold which contacts the first and second rear plates and the support frame so that the first mold opposes the second mold, of elastically deforming the plate-shaped first and second mirrors, the plate-shaped first and second rear plates, and the support frame so that the reflecting surfaces of the plate-shaped first and second mirrors form one three-dimensional curved surface, and of maintaining the elastically deformed condition of the plate-shaped first and second mirrors, the plate-shaped first and second rear plates and the support frame until the adhesive agent is cured,
- wherein the support frame comprises a columnar shaft that connects together the first rear plate and the second rear plate, and
- wherein the columnar shaft is disposed between the first rear plate and the second rear plate.
A mirror structure that radiates solar light to a heat receiver, the structure comprising:
- first and second mirrors each having a reflecting surface that reflects the solar light and forms one rotation symmetry surface;
- a first rear plate that supports a rear surface of the first mirror;
- a second rear plate that supports a rear surface of the second mirror;
- and
- a support frame that is disposed on rear surfaces of the first and second rear plates,
- wherein the first and second mirrors, the first and second rear plates, and the support frame are joined to each another to elastically deform so that the reflecting surfaces of the first and second mirrors form one three-dimensional curved surface, and the elastically deformed condition of the first and second mirrors, the first and second rear plates and the support frame is maintained,
- wherein the first mirror is joined to the first rear plate by adhesive agent,
- wherein the second mirror is joined to the second rear plate by adhesive agent,
- wherein the adhesive agent is elastic adhesive agent,
- wherein the support frame comprises a columnar shaft that connects the first rear plate and the second rear plate, and
- wherein the columnar shaft is disposed between the first rear plate and the second rear plate.
