管道相对标高的画法:
1、在无法标注垂直尺寸的图样中,应标注标高。标高应以m为单位,并应精确到cm或mm。
2、标高符号应以直角等腰三角形表示。当面标准层较多时,可只标注与本层楼(地)板面的相对标高。
3、水、汽管道所标高未予说明时,应表示为管中心标高。
4、水、汽管道标注管道外底或顶标高时,应在数字前加“底”或“顶”字样。
5、矩形风管所注标高应表示管底标高;圆形风管所注标高应表示管中心标高。当不采用此方法标注时,应进行说明。
6、平面图中无坡度要求的管道标高可标注在管道截面尺寸后的括号内。必要时,应在标高数字前加“底”或“顶”的字样。
相对标高的画法
管道截面尺寸的标注符号及画法:
1、低压流体输送用焊接管道规格应标注公称通径或压力。公称通径的标记应由字母“DN”后跟一个以亳米表示的数值组成;公称压力的代号应为“PN”。
2、输送流体用无缝钢管、螺旋缝或直缝焊接钢管、铜管、不锈钢管,当需要注明外径和壁厚时,应用“D(或Φ)外径×壁厚”表示。在不致引起误解时,也可采用公称通径表示。
3、塑料管外径应用“de”表示。
4、圆形风管的截面定型尺寸应以直径“Φ”表示,单位应为mm.
5、矩形风管(风道)的截面定型尺寸应以“A×B”表示。“A”应为该视图投影面的边长尺寸,“B”应为另一边尺雨。A、B单位均应为mm。
6、水平管道的规格宜标注在管道的上方;竖向管道的规格宜标注在管道的左侧。双线表示的管道,其规格可标注在管道轮廓线内。

祖芸强2695如何正确安装消防给水管道,看看你都装对了吗 -
徐项夜15049741230 ______ 如何正确安装消防给水管道,看看你都装对了吗? 施工程序 施工顺序是:先地下后地上,先干线和主管,后支线或支管,每道工序施工完毕后邀请业主、监理工程师进行检评、隐蔽.然后进行下一道工序的施工. 主要施工方法 1、预留预埋 (...
祖芸强2695消防竖管的设置 - 消防竖管的设置要求多少米
徐项夜15049741230 ______ 1. 消防竖管的设置要求多少米消防水管卡口每隔3~4m一个, 楼层高度小于或等于5m,每层必须安装1个.楼层高度大于5m,每层不得少于2个.在“建筑防火设计规范”...
祖芸强2695消火栓箱安装规范 -
徐项夜15049741230 ______ 消火栓栓口距地宜为1.1m. 消火栓箱有很多种啊,有单栓箱、组合式箱体等等,没有规范规定箱体的安装高度问题 箱体安装注意门的开启方向(开门见栓)、角度大小(越大越好)就ok
祖芸强2695消防管安装规范有哪些 -
徐项夜15049741230 ______ 消防管道施工规范主要有:《自动喷水灭火系统施工及验收规范》(GB50261-2005)及《建筑给水排水及采暖工程施工质量验收规范》(GB 50242-----2002)中的消火栓部分.
祖芸强2695'首层主管开消防支管消防箱阀门多高
徐项夜15049741230 ______ 消火栓立管入户后,首层阀门 安装高度为距地面400-500mm,指的是阀门中心距离建筑地面的标高,因为消火栓引出支管连接消防箱的管中高度为距离建筑地面850mm,而要求沟槽管件之间的间距不得小于150mm且不小于管径
祖芸强2695双栓消防箱的双出口距离是多少 -
徐项夜15049741230 ______ 甲型双栓消火栓箱两栓头中间间距为420,乙型双栓消火栓箱两栓头中间间距为470,丁型双栓消火栓箱两栓头中间间距为410,丙型为直接在消火栓箱居中进管. 消火栓栓口中心距地面高度为1.1米.消火栓栓口中心距消防箱侧边框为单栓15厘米(也可安装在箱子中间),双栓12厘米.消火栓栓口中心距消防箱底为14厘米.带自救卷盘的消防箱栓口距箱底为22厘米.消火栓立支管管中心距箱后面为10厘米.室外消防水泵结合器栓口距地70厘米. 室内消火栓箱由其箱门开启方式与水带放置形式的不同,可分为甲、乙、丙、丁、戊、已型,详细请到百度文库下载一个(04S202)《室内消火栓安装》图集,即可详细分辨清楚.
祖芸强2695消防立管支架规范选材 -

祖芸强2695消防立管安装时,对焊接接口都有什么具体要求? -
徐项夜15049741230 ______ 焊口打磨干净不能有毛刺、20mm范围内不能有油渍等污染物,对接不错口,保证管道同心度和垂直度就差不多了
祖芸强2695室内消火栓双双箱入箱支管的规范 -
徐项夜15049741230 ______ 1.设置双栓是有规定的. 《建筑设计防火规范》规定:单元式、塔式住宅的消火栓宜设置在楼梯间的首层和各层楼层休息平台上,当设2 根消防竖管确有困难时,可设1 根消防竖管,但必须采用双口双阀型消火栓. 你们所住的楼是宿舍楼还是住宅楼,如果是宿舍楼是不许设双栓,应设单栓. 2.双栓接法有几种,见04S202图集.一类是从总立管上接出一根DN80横管,再在DN80管上接出两根DN65入箱接消火栓,还有一种一根DN80从总立管上接出后入箱接双栓头. 3.消火栓管径是在消防流量一定时通过控制流速(不大于2.5m/s)来确定的. 你看一下你建筑室内消防流量是多少,查水力计算表,看其流速是否超过2.5m/s.
祖芸强2695大家好,消防水箱在十层屋面,一至九层,每层有12个自动喷淋头,请问主管应用多大管径?用DN80的行 -
徐项夜15049741230 ______ 按照楼主说的,十层楼,每层12个喷头,不外乎塔楼住宅或者单元公寓,性质为中危险1级,管径布置要求50可以连接8个喷头,65可以带11个,80可以带16个,所以采用80可以,但是立管管径需要满足25l-30l水量(这个看设计取得) ,需要150
