第二节 钢柱安装工艺

Second section steel column installation process

一、钢柱的吊装

1. Hoisting of steel columns

1、对基础进行复测，包括锚栓的露出长度，锚栓中心线对基准线的位移偏差，锚栓间距，基础标高，对于不合格的进行处理后方可进行吊装。

1. The retest of the base, including the length of the anchor bolt, the displacement deviation of the anchor center line to the base line, the spacing of the anchor bolt, the base elevation, can be hoisted after the disqualification is processed.

2、为了控制柱子的安装标高，还事先在柱子可视的截面上划出500mm 的位置，以便安装时进行标高的微调、校正。在复测合格的基础上安装钢柱，首先用单支钢丝绳将柱子捆绑好，吊点位置选择在距柱端1/3 柱长的位置。通过旋转法将柱子吊起，将钢柱吊起送至安装位置。绑扎处应设加垫。

2, in order to control the installation height of columns, the position of 500mm is also projected on the column visible section in advance, so that the elevation adjustment and correction should be carried out when installing. The steel column is installed on the basis of repeated measurements. First, a single wire rope is used to bind the columns. The location of the lifting points is chosen at the position of 1/3 column away from the column ends. The column is lifted by rotating method, and the steel column is lifted to the installation position. A padding should be set at the binding site.

二、钢柱的校正

Two, correction of steel column

1、在柱子可视面上事先画出中心线，然后在两个相互垂直的方向用经纬仪对柱子的垂直度进行调整。

1, draw the center line on the column visibility plane, then adjust the verticality of the column in the two perpendicular directions.

2、通过测量柱子内侧距建筑物上弹好的控制线的距离来控制柱子的垂直度。

2, we should control the perpendicularity of the column by measuring the distance between the inner side of the column and the control line that is good enough for the building.

3、柱子的标高、轴线和垂直度偏差的调整是相互联系的兼顾的，待所有标准都达到时才算完成校正工作。

3, the adjustment of the column's elevation, axis and perpendicularity deviation is related to each other. When all standards are met, the correction work is completed.

第三节 钢梁安装工艺

Third section steel beam installation process

将钢梁卸车到各柱附近，用汽车吊送到楼层面，再由桅杆吊安装，有部分构件重的主梁可以和汽车吊进行台吊。次梁可以用自制轮胎式（5t）起重机安装。从三区开始、先主梁后次梁再檩条，逐根按编号用桅杆吊安装钢梁，只有当梁两端安装螺栓紧固（或点焊牢固）后，方可松钩，依次吊装其它钢梁。检验合格后进行焊接。

The steel beam will be transported to the columns near the columns, and it will be lifted to the floor level by car. Then it will be installed by the mast crane. Some main members with heavy components can be hoisted with the truck crane. The secondary beam can be installed by a self built tire type (5T) crane. Starting from the three area, the second beam of the main beam is then purlin, and the steel beam is installed by the mast by number by number. Only when the bolt is fastened (or the spot welding is firm), the hook is loose and the other steel beams are hoisted in turn. After the inspection is qualified, the welding is carried out.
