(a) according to the design requirements and reference datum line to find the wind pipe elevation of Civil Engineering

(二)   制作吊架及高吊点

(two) making hanger and high hanging point

1、标高确定后，按照风管系统所在的空间位置，确定风管支、吊架形式。

1, after the elevation is determined, according to the location of the air duct system, the form of the wind pipe support and hanger is determined.

2、风管支、吊架的制作图参照《建筑设备施工安装图集》(91SB6)的用料规格和做法制作。

2, the drawing of air duct support and hanger is made according to the material specifications and methods of construction equipment installation Atlas (91SB6).

3、吊点的设置：

3. The setting of the hanging point:

（1）  预埋件法：

(1) embedded method:

①  前期预埋：一般由预留人员将预埋件按图纸坐标位置和支、吊架间距，牢固固定在土建结构钢筋上。

(1) pre embedding: generally, the embedded parts are firmly anchors on the reinforced bar of the civil structure according to the drawing coordinate position and the distance between the supports and hangers.

②  后期预埋：

The late pre buried:

在砖墙上埋设支架：根据风管的标高算出支架型钢上的表面离地距离，找到正确的安装位置，打出80mm×80mm的方洞。洞的内外大小应一致，深度比支架埋进墙的深度大30～50mm。打好洞后，用水把墙洞浇湿，并冲出洞内的砖屑。然后在墙洞内先填塞一部分1:2水泥砂浆，把支架埋入，埋入深度一般为150～200mm。用水平尺校平支架，调整埋入深度，继续填塞砂浆，适当填塞一些浸过水的石块和碎砖，便于固定支架。填入框格护坡模具 箱体护坡模具 华尔街铜牛 电阻柜 接地电阻柜 电缆保护接地箱 隔离墩模具 化粪池模具水泥砂浆时，应稍低于墙面，以便土建工种进行墙面装修。

Set up the scaffold on the brick wall: according to the height of the wind pipe, calculate the ground distance from the surface of the stenting type steel, find the correct installation position, and break out the square hole of 80mm * 80mm. The inside and outside size of the hole should be consistent, and the depth is 30 to 50mm larger than the depth of the embedded wall. After a good hole is made, water is used to wet the wall hole and rush out of the brick in the hole. Then, a part of 1:2 cement mortar is filled in the wall hole, and the support is embedded. The depth of embedment is generally 150 to 200mm. Leveling bracket with horizontal ruler, adjusting embedding depth, continuing to fill mortar, and properly filling some stones and broken bricks which are soaked in water, so as to facilitate fixing support. When filling in cement mortar, it should be slightly lower than the wall so that the civil works can be decorated on the wall.
