安装准备

Installation preparation

1、复验安装定位所用的基础中心轴线、基础支承面标高或地脚螺栓的标高，并量出螺栓的具体位置，做好检测记录，超出允许偏差时，应做好技术处理。

1 installation location, the reinspection center axis, the basis of the foundation bearing surface elevation or elevation of the anchor bolt, and the location of the measure bolt, completes the inspection record, exceed the allowable deviation, should do well in technical processing.

2.钢柱基础混凝土强度必须达到设计强度，基础回填土已进行完毕。

The concrete strength of the steel column must reach the design strength, and the basic backfill soil has been completed.

3、地脚螺栓(锚栓、应垂直，露出长度和丝牙长度应满足设计要求。丝牙无损伤，螺帽能紧到位。

Anchor bolt (anchor bolt, should be perpendicular, reveal length and thread length should meet the design requirement. The silk tooth is not damaged, the nut will be tight in position.

4、检查吊装机械及吊装机具。检查钢丝绳、滑轮、卡扣等能否满足使用要求，按专项施工方案要求搭设必要的脚手架或平台。

Inspect crane machinery and equipment. Check whether the wire rope, pulley, and buckle can meet the requirement of use, and set up the necessary scaffold or platform according to the special construction plan.

5、钢柱、钢梁、屋架等成品、半成品的吊装，应编制吊装方案。对设计的拉杆在吊点位置，使受力改变为压杆时，为防止杆件失稳变形，必要时应加固和验算。

Steel column, steel girder, roof and other finished products, semi-finished hoisting, should be prepared to plan. In the case of the lever of the design, it is necessary to strengthen and verify when the force changes to the pressure bar.

6、钢构件吊装前应清除其表面上的油污、冰雪、泥沙和灰尘等杂物。

The oil, snow, silt and dust should be removed before the steel components are hoisted.
