玻璃钢又称玻璃纤维增强塑料,它以比重轻(约1.4～1.9)、强度高、质地硬、密实性好、耐腐蚀及电绝缘性好而受到人们重视。本文介绍某天体望远镜观察室球壳双层圆顶玻璃钢施工的方法。天体观察室内圈直径5米,壳盖要求保温,且能转动,外圈壳盖直径为5.6米,需能掀起0°～90°的不同角度。球壳下为36厘米厚砖墙,聚酯玻璃钢球壳的具体构造见图1。一、施工工艺 1.模具用接触成型法制造玻璃钢,模具是关键。因壳体内面要求光滑平整,故选择木骨
Glass fiber reinforced plastic, also known as glass fiber reinforced plastic, has attracted attention due to its light weight (about 1.4-1.9), high strength, hard texture, good compactness, corrosion resistance, and good electrical insulation. This article describes the method of construction of a spherical double-deck glass fiber reinforced plastic dome of an astronomical telescope observation room. The celestial body observes that the inner ring is 5 meters in diameter, the shell cover requires thermal insulation, and it can rotate. The diameter of the outer shell cover is 5.6 meters. It needs to be able to set off different angles from 0 degrees to 90 degrees. Under the spherical shell is a 36 cm thick brick wall. The concrete structure of the polyester fiberglass spherical shell is shown in Figure 1. First, the construction process 1. Mold with contact molding glass steel manufacturing, mold is the key. Because the inner surface of the shell is required to be smooth and flat, the wood bone is selected
