楼梯面、剖面画法.docVIP

　2、楼梯剖面图 楼梯剖面图是用一假想的铅垂剖切平面，通过各层的同一位置梯段和门窗洞口，将楼梯剖开向另一未剖到的梯段方向作正投影，所得到的剖面投影图。通常采用150的比例绘制。 在多层房屋中，若中间各层的楼梯构造相同时，则剖面图可只画出底层，中间层（标准层）和顶层，中间用折断线分开；当中间各层的楼梯构造不同时，应画出各层剖面。图示为某小区别墅楼梯的剖面图。 ? 3、楼梯节点详图 　　楼梯节点详图主要包括楼梯踏步、扶手、栏杆（或栏板）等详图。常选用建筑构造通用图集中的节点做法，与详图索引符号对照可查阅有关标准图集，得到它们的断面形式、细部尺寸、用料、构造连接及面层装修做法等。 4、楼梯详图的画法 （1）楼梯平面图 　　1）首先画出楼梯间的开间、进深轴线和墙厚、门窗洞位置。确定平台宽度、梯段宽度和长度，如图8.34a所示。 　　2）采用两平行线间距任意等分的方法划分踏步宽度，如图8.34b所示。 　　3）画栏杆（或栏板），上下行箭头等细部，检查无误后加深图线，注写标高、尺寸、剖切符号、图名、比例及文字说明等。 完成后的楼梯平面图见图8.32。 　　（2）楼梯剖面图 　　1）画轴线、定室内外地面与楼面线、平台位置及墙身，量取楼梯段的水平长度、竖直高度及起步点的位置 　　2）用等分两平行线间距离的方法划分踏步的宽度、步数和高度、级数，如图8.35b所示。 　　3）画出楼板和平台板厚，再画楼梯段、门窗、平台梁及栏杆、扶手等细部，如图8.35c所示。 　4）检查无误后加深图线，在剖切到的轮廓范围内画上材料图例，注写标高和尺寸，最后在图下方写上图名及比等。 完成后的楼梯剖面图见图8.33。 attention to improving the quality and efficiency of development and pay more attention to security and reform the peoples livelihood, more focus on maintaining social harmony and stability, and promote the development of township economy in a better and faster, create a new normal XX development and lay a more solid foundation for XX build a well-off society. Completed tasks this year, we must always pay special attention to the primary task of development. XX weak economic base, low levels of development, economic construction is the Center, we have to create conditions for faster economic development, accumulating more wealth, better peoples lives. Effort should be made to this years economic growth, revenue growth, people have maintained a high rate of income growth, GDP growth of more than 15 per cent respectively. Always grasp the fundamental impetus for reform. We are now no soldiers behind many indicators ranked in the bottom of the county from getting bigger. Only by going all out to hard work, hard work, innovation, reform does not adapt to institutional mechanisms, practices, it is possible to change the face of XX poor, into a well-off society together with people across the country. We want to break the old patterns of thinking, methods and organization
