Further improve, the outer steel skeleton uses riveting to fix with exterior skin, and interior steel skeleton is with inside panel using riveting
Fixed, riveting is solid and reliable.
Further improve, lightning rod is provided with the outer canopy of the heavens, the grounding resistance of lightning rod is less than 10 ohm, safely may be used
Lean on.
Compared with prior art, the utility model has the advantages that：
By setting sound-absorbing spongy layer, erasure effect is played, prevents from, because showing astronomical phenomena performance in planetarium, causing noise dirty
Dye, disturbs neighbouring resident etc..Additionally by outer steel skeleton, interior steel skeleton is set, strengthen the stability of the whole canopy of the heavens, prevent big
Wind causes it to rock, or even deforms, collapses.By setting shading waterproof cloth, to avoid the light through the outer canopy of the heavens and condensation
Water enters the interior canopy of the heavens.
