如今桥架在日常的生产生活中的应用已经相当普遍了，但值得一提的是，其安装需要遵守一定的流程以及其他方面的注意事项才能保障安全，那么山东桥架安装时的定额套用是怎样的？

　　Now the application of bridge in daily production and life has been quite common, but it is worth mentioning that its installation needs to comply with certain processes and other matters needing attention to ensure safety, so what is the quota application of shandong bridge installation?

　　桥架安装定额应根据桥架的型号和长度确定。使用宽度加高度乘以2来设置配额的方法是不正确的，因为定额是在计算工程量后，根据施工方法和工序的区别，在定额中找到相应的分项，得到相应的综合单价，再乘以计算出的工程量，然后得到总价。因此，不可能在没有基础的情况下将宽度乘以两倍。

　　The bridge installation quota should be determined according to the type and length of the bridge. The method of using width plus height multiplied by 2 to set quota is not correct, because quota is in the calculation of quantities, according to the difference between construction methods and working procedures, find the corresponding sub-items in the quota, get the corresponding comprehensive unit price, and then multiplied by the calculated quantities, and then get the total price. Therefore, it is impossible to double the width without a basis.

　　工程量计算规则：桥架安装应按设计图示中心线，以“m”为计量单位，均不扣除变通、三通、四通等配件所占长度。桥架安装定额已包括：运输、组对、吊装、固定；弯通或三、四通修改，制作组对；切割口防腐、桥架开孔、上管件、隔板安装、盖板安装、接地、附件安装等工作内容，不得另计。

　　Calculation rules of engineering quantity: bridge installation should be in accordance with the center line of the design diagram, with “M” as the unit of measurement, without deducting the length of flexible, three-way, four-way and other accessories. The bridge installation quota has included: transportation, group pair, lifting, fixing; Bending or three, four way modification, production group pair; Anti-corrosion of cutting mouth, opening of bridge frame, upper pipe fitting, partition plate installation, cover plate installation, grounding, attachment installation and other work shall not be included in the calculation.

山东桥架支撑架项目适用于立柱、托臂及其他各种支撑架的安装。项目中已综合考虑了采用螺栓、焊接和膨胀螺栓三种固定方式，实际施工中，不论采用何种固定方式，均不作调整（注意：桥架支撑架定额适用成品支架，对于用角钢和丝杆另外制作桥架支架可以套用铁构件制作、安装定额号。）

　　Shandong bridge support frame project is suitable for column, bracket and other kinds of support frame installation. Project has been considering using bolts, welding and expansion bolt three fixed way, in the actual construction, no matter adopt what kind of fixed mode, are not adjusted （note: bridge brace quota for product support, for made of Angle steel and wire rod and bridge bracket can apply iron components production, installation fixed number.）

　　此外，山东桥架选型时要考虑具体项目现场的安装条件，选用合适类型、合适表面处理工艺的钢制电缆桥架才行，更多内容就来网站 www.comprepyme.com进行咨询吧！
