巷柱式采煤
补充资料:柱式
柱式
一种建筑结构的样式。它的基本单位由柱和檐构成。柱可分为柱础、柱身、柱头(柱帽)三部分。由于各部分尺寸、比例、形状的不同,加上柱身处理和装饰花纹的各异,而形成各不相同的柱子样式。古典柱式是西方古典建筑的重要造型手段。典型的古典柱式包括希腊时期的3种,共有5种:多立克式、爱奥尼克式、科林斯式、塔司干式、复合式。其中塔司干式和复合式是在前三种希借柱式的基础上发展起来的两种罗马柱式。多立克式柱身比例粗壮,由下而上逐渐缩小,柱子高度为底径的4-6倍。柱知刻有凹圆槽,槽背成棱角,柱头比较简单,无花纹,没有柱础而直接立在台基上檐部高度的比例为1:4,柱间距约为柱么匠1.2至1.5倍。爱奥尼克式的柱身比例修长,上下比例变化不显著,柱子高度为底径的9至10倍,柱身刻有凹圆槽,槽背呈带状,有多层的柱础,檐部高度与柱高的比例为1:5,柱间距为柱径的2倍。科林斯工除了柱头如盛满卷草花篮的纹饰外,其它各部分与爱奥尼克式相同。塔司干式的柱身比例较粗,无圆槽、有柱础的一种简单柱式。复合式则在科林斯式柱头上加上一对爱奥尼式的涡卷,柱式趋向华丽、细密、纤巧和豪华。
