1、 Installation conditions:

在安装内钢外铝高隔间的过程中需要多种角码，必须由技术人员进行安装，才能达到安装成果。

A variety of corner codes are required during the installation of inner steel and outer aluminum high compartment, which must be installed by technicians in order to achieve the installation results.

内钢外铝隔间的选择应根据实际情况，如墙体的承载力，如内钢外铝隔间与装饰墙的配色等，考虑整体成果是内钢外铝隔间安装的基本理念。

The selection of inner steel and outer aluminum compartment shall be based on the actual situation, such as the bearing capacity of the wall, such as the color matching between inner steel and outer aluminum compartment and decorative wall. The overall achievement is the basic concept of the installation of inner steel and outer aluminum compartment.

二、工艺流程：

2、 Process flow:

在墙上捕捉水平线→安装顶部埋件→安装底部埋件→隐蔽检查→内衬钢板的焊接→内钢外铝型材接头的预装配→顶部钢板的焊接→整平→完成清洁→逐项验收。

Capture the horizontal line on the wall → install the top embedded parts → install the bottom embedded parts → concealed inspection → welding of inner steel plate → pre assembly of inner steel and outer aluminum profile joints → welding of top steel plate → leveling → cleaning → acceptance item by item.

三、施工方法

3、 Construction method

（1）弹线：根据楼层标高水平线和设计标高，沿墙弹内钢外铝高隔间标高水平控制线，并注意是否与水电站高程相矛盾，如有矛盾，应及时。

(1) Snap the line: snap the elevation horizontal control line of the internal steel and external aluminum high compartment along the wall according to the floor elevation horizontal line and design elevation, and pay attention to whether it is inconsistent with the elevation of the hydropower station. If there is any contradiction, it shall be solved in time.

（2）划分：根据内钢外铝隔间外立面的划分设计要求，制定详细的施工划分方案。确定每个立面的准确网格尺寸，悬挂水平线和垂直线，绘制网格线，并沿墙上端从上到下（或从下到上）一行一行地施工。

(2) Division: according to the division design requirements of the external facade of the inner steel and outer aluminum compartment, a detailed construction division scheme shall be formulated. Determine the accurate grid size of each elevation, hang horizontal and vertical lines, draw grid lines, and construct line by line from top to bottom (or from bottom to top) along the upper end of the wall.

（3）预埋件安装：弹好标高水平线后，确定内钢外铝隔间的标高，将预埋钢板固定在混凝土结构中，将预埋钢板固定在底部结构梁中，安装内钢外铝型材时焊接内衬钢管。

(3) Installation of embedded parts: after snapping the elevation horizontal line, determine the elevation of the inner steel and outer aluminum compartment, fix the embedded steel plate in the concrete structure, fix the embedded steel plate in the bottom structural beam, and weld the lined steel pipe when installing the inner steel and outer aluminum profiles.

安装时，在内钢外铝高隔间墙体相应网格线上标出膨胀地脚螺栓的坐标，用电钻钻钻地脚螺栓孔，放置膨胀塞。使用膨胀塞时，地脚螺栓孔的深度大于塑料膨胀塞LCM。

During installation, the coordinates of the expansion anchor bolts shall be marked on the corresponding grid line of the inner steel and outer aluminum high compartment wall, the anchor bolt holes shall be drilled with an electric drill, and the expansion plug shall be placed. When using expansion plug, the depth of anchor bolt hole is greater than that of plastic expansion plug LCM.

两端与墙埋件焊接，铝方管上下埋件焊接，中性齿轮50mm，由50mmU型不锈钢件隔开。

Both ends are welded with wall embedded parts, the upper and lower embedded parts of aluminum square pipe are welded, and the neutral gear is 50mm, separated by 50mm U-shaped stainless steel parts.

（4）预装：按规格将铝方管预装成一组，10根一排，用木制固定槽预固定。注意地面平整干净，检查杏铝方管拼接平整度，接口牢固，每两排用顶钢板覆盖焊接，调整水平线和垂直线。

(4) Pre assembly: pre assemble the aluminum square tubes into a group according to the specifications, 10 in a row, and pre fix them with wooden fixing slots. Pay attention to the flatness and cleanness of the ground, check the splicing flatness of apricot aluminum square pipe and the firm interface, cover and weld each two rows with top steel plate, and adjust the horizontal line and vertical line.

在同一立面两侧的阳角处悬挂水平线和垂直线，粘贴固定。沿建筑物屋顶或梁的水平方向施工，并根据需要预留水平和垂直分隔缝，以调整和校正成品方管。

Hang horizontal lines and vertical lines at the external corners on both sides of the same facade and paste them for fixation. Construct along the horizontal direction of the building roof or beam, and reserve horizontal and vertical separation joints as required to adjust and correct the finished square pipe.

（5）调整和固定：当出现需要调整的误差时，应立即安装和调整内钢外铝高隔间，轻轻揉捏和移动。严禁将固定好的铝方头向外拉，或用手或橡皮锤上下左右均匀敲击管面，焊接上下。

(5) Adjustment and fixing: when there is an error to be adjusted, the inner steel and outer aluminum high compartment shall be installed and adjusted immediately, kneaded and moved gently. It is forbidden to pull the fixed aluminum square head outward, or knock the pipe surface up and down, left and right evenly with hand or rubber hammer, and weld up and down.
