正面防腐后将房架翻身进行反面焊接，反面焊接时注意角钢的方向应与正面一致，焊后再进行支脚焊接与防腐。房架翻身时，利用三角架完成，不可强行翻转，以免房架变形。
c.
Welding on the reverse side of the room frame. After anti-corrosion on
the front side, turn over the house frame for reverse welding. When
welding on the reverse side, pay attention to the direction of the angle
steel should be consistent with the front side. After welding, perform
support foot welding and anti-corrosion. When turning over the house
frame, use a tripod to complete it, and do not forcefully flip it to
avoid deformation of the house frame.
d.当完成房架制作后，应对其补漆，并摆放在成品区，以方便下一个房架的制作及装车运输。摆放时摆放方式要正确性，支承要合理，避免构件产生塑性变形。
d.
After completing the production of the frame, it should be repainted
and placed in the finished product area for the convenience of the next
frame production and loading transportation. When placing, the placement
method should be correct, and the support should be reasonable to avoid
plastic deformation of the components.
(2)结构安装：
(2) Structural installation:
a.安装前根据总包方提供的建筑物轴线、标高及其轴基准点、标高水准点，复测轴线和标高。找出预埋件位置,对预埋件测量弹线。
a.
Before installation, re measure the axis and elevation according to the
building axis, elevation and its axis reference point, elevation
benchmark provided by the General Contractor. Find the position of the
embedded parts and measure the snap lines on the embedded parts.
b.支撑钢柱的安装与固定。钢柱的安装靠吊车吊至安装点后利用线锤进行找正，找正方法如下：
b.
Installation and fixation of supporting steel columns. The installation
of steel columns is carried out by lifting them to the installation
point with a crane and using a plumb bob for alignment. The alignment
method is as follows:
在钢柱圆周方向分出两个相互垂直的点，并沿轴线方向测出一条相等线段，用线锤吊线，测量轴线上下点与线锤的距离是否相等。找正后应立即固定，固定后再松开吊钩。
Divide
two mutually perpendicular points in the circumferential direction of
the steel column, and measure an equal line segment along the axis
direction. Use a plumb bob to hang the line and measure whether the
distance between the upper and lower points of the axis and the plumb
bob is equal. After alignment, it should be fixed immediately and then
the hook should be released.
c.完成房架的绑扎翻身与就位。房架的绑扎点应在上弦节点附近，翻身扶直房架时，吊索与水平线的夹角不可小于60度，吊装时不可小于45度，绑扎点应以房架的重心为中心，对称布置。考虑房架的侧向刚度较差，在翻转时，应进行临时加固。
c.
Complete the binding, flipping, and positioning of the room frame. The
binding point of the room frame should be near the top chord node. When
turning over and straightening the room frame, the angle between the
sling and the horizontal line should not be less than 60 degrees, and
when lifting, it should not be less than 45 degrees. The binding point
should be symmetrically arranged centered around the center of gravity
of the room frame. Considering the poor lateral stiffness of the house
frame, temporary reinforcement should be carried out during flipping.
