1、 风管安装 按施工图示不同规格以展开“面积”计算,不扣除检查孔、测定孔、送风口、吸风口等所占面积。计算风管长度时,一律以施工图示线长度为准(主管与支管以其线交点划分),包括弯头、三通、变径管、天圆地方等管件的长度,但不得包括帆布、风阀、消声器、设备所占长度。直径和周长按图示尺寸为准展开。报价时定额已含损耗,计算结果不需要乘损耗系数。

1. The air duct installation shall be calculated according to the "area" of different specifications in the construction drawing, and the area occupied by inspection hole, measurement hole, air supply outlet, air suction outlet, etc. shall not be deducted. When calculating the length of the air duct, the length of the center line in the construction drawing shall prevail (the main pipe and branch pipe shall be divided by the intersection of the center line), including the length of elbow, tee, reducer, round place and other pipe fittings, but shall not include the length occupied by canvas, air valve, muffler and equipment. The diameter and perimeter shall be expanded according to the dimensions shown in the figure. The quota includes loss when quoting, and the calculation result does not need to be multiplied by loss coefficient.

2、薄钢板通风管道、 净化通风管道 ,复合型风管(玻纤板、不燃无机复合风管),报价定额内已包括法兰、加固框和吊托支架,不另行计算。但不包括过跨风管落地支架,因此过跨风管落地支架需按图按规范计算重量。

2. Sheet steel ventilation duct, purification ventilation duct and composite air duct (fiberglass board and incombustible inorganic composite air duct). The quotation quota has included flange, reinforcement frame and lifting support, which will not be calculated separately. However, it does not include the floor support of over span air duct, so the weight of the floor support of over span air duct shall be calculated according to the drawings and specifications.

3、 不锈钢通风管道 、铝板通风管道,风管咬口连接中报价定额包括管件、法兰,但不包括吊托支架,焊接连接中报价定额仅包括管件,不包括法兰和吊托支架,其工程量以“kg”为计量单位,故根据风管连接方式按设计说明或规范计算法兰和吊托支架重量。

澳门金牛版1877-澳门彩1877cc-1877彩票购彩大厅-1877.cc彩票3. The quotation quota of stainless steel ventilation pipe, aluminum plate ventilation pipe and air pipe undercut connection includes pipe fittings and flanges, but does not include lifting bracket. The quotation quota of welding connection only includes pipe fittings, excluding flange and lifting bracket. The quantities are measured in "kg". Therefore, the weight of flange and lifting bracket is calculated according to the design description or specification according to the connection mode of air pipe.

(参考已施工项目结算数据:法兰(不锈钢角铁3#)的含量测算0.9kg/m2;吊托支架(不锈钢角铁4#、不锈钢槽钢6#)含量测算:1.5kg/m2;若其他项目有类似工程请及时提供数据及时更正;)

澳门金牛版1877-澳门彩1877cc-1877彩票购彩大厅-1877.cc彩票(refer to the settlement data of constructed projects: the content of flange (stainless steel angle iron 3#) is calculated to be 0.9kg/m2; Calculation of the content of lifting bracket (stainless steel angle iron 4#, stainless steel channel steel 6#): 1.5kg/m2; If there are similar projects in other projects, please provide data and correct them in time;)

澳门金牛版1877-澳门彩1877cc-1877彩票购彩大厅-1877.cc彩票4、风管软接,(1)帆布接口,按图示尺寸以“平方米”计算,一般宽度为250mm,具体以现场制作经验考虑。(2)软管风管,按图纸尺寸以“米”计算。

4. Flexible connection of air duct, (1) canvas interface is calculated in "square meter" according to the size shown in the figure, and the general width is 250mm, which is considered based on the on-site manufacturing experience. (2) Hose duct, calculated in "meters" according to the size of the drawing.

5、风管导流叶片,按风管规格计算弯头个数,按下表计算导流叶片“面积”。

5. For the air duct guide vane, the number of elbows shall be calculated according to the air duct specification, and the "area" of the guide vane shall be calculated according to the following table.

6、风口风阀,按不同类型(防火阀、蝶阀、对开多叶阀、散流器、百叶等)不同规格以“个”为计量单位(按成品计算)。

6. The air valve at the air outlet shall be measured in "pieces" according to different types (fire damper, butterfly valve, split multi leaf valve, diffuser, louver, etc.) (calculated according to finished products).

7、消声器、消声静压箱、静压箱,按不同规格以“台”为计量单位(按成品计算),除设计要求现场制作时以“平方米”(展开六个面面积)计算。

澳门金牛版1877-澳门彩1877cc-1877彩票购彩大厅-1877.cc彩票7. Silencer, silencing static pressure box and static pressure box shall be measured by "table" according to different specifications (calculated according to finished products). Except for the design requirements, it shall be calculated by "square meter" (expanded area of six surfaces) during on-site production.
