1、划线下料:水落管一般用26号白铁皮制作,有方形和圆形两种,本工艺以圆形为准。大小头宽度及留出咬口用钢针划出标点,大小头周长差5~6mm,用钢直尺划裁板线,大小头互为颠倒依次划线,划线后经校核无误后,先裁出样板,然后进行下料。
1, marking the blanking: the water pipe is usually made of white iron sheet No. 26, with two squares and circles. The width and the bite mouth of the big head are marked out with the steel needle, the length of the large small head is 5 to 6mm, and the plate line is cut with the steel straight ruler. The size head is crossed in turn in turn. After the scratch is checked, the sample is cut out first and then the blanking is carried out.
2、成形咬口:水落管一般采用平咬口,先将铁皮的边口对齐方钢角,推至咬口线,用方木向下轻打打出咬口然后将铁皮翻身调头,将另一边的咬口敲出,再依次对准各线打折90度,最后将咬口敲紧,此时套在圆管上用手工压成圆弧形,用力要均匀,不压出棱角。水落管咬口也可用咬口机制作,为便于套紧,大小头直径差1.5mm,并将小头剪出三角形做记号。
2, forming bite mouth: the water pipe usually uses the flat bite mouth, first aligns the edge of the iron sheet to the square steel angle, pushes it to the bite line, then hits the bite with the square wood down, then turns the iron skin into the head, then knocks the bite out on the other side, then turns 90 degrees on the lines in turn, and finally tightens the bite, then the sleeve is pressed by hand on the round tube. Circular arc, force to be uniform, do not press out of angle. The nozzle can also be made by the bite machine, which is easy to tighten. The diameter of the small head is 1.5mm, and the small head is cut out as a triangle.
3、油漆:水落管制成后,先将表面污迹灰尘除净,然后里外满涂防锈漆一道,凉干后再刷一道铅油;用镀锌薄钢板制作时,其厚度应为0.45~0.75mm,并应里外涂刷锌磺类或磷化底漆;如用薄钢板制作时,成形后应涂刷两度红丹油或铁丹油;安装完毕后,涂刷最后一道调和漆。
3, paint: after the water is controlled, the surface dirt is cleaned first, then the paint is covered with antirust paint, and then a lead oil is brushed after dry. The thickness of the galvanized steel sheet should be 0.45 ~ 0.75mm, and the zinc or phosphating primer should be painted inside and outside, and when the steel sheet is made with a thin steel plate, two degrees red oil should be painted after forming. Or iron Dan oil; after installation, apply the last blend paint.
4、水落管安装:安装水落管随外檐抹灰架子由上往下进行,先在水落口处吊线坠弹出直线,用钢錾子在墙上打眼,按直线用水泥砂浆埋入卡子铁脚,卡子间距1.2m一个,卡子露出墙面2cm左右,待水泥砂浆达到强度后再安装水落管;有马腿弯时上口必须压进水斗嘴内5~6cm,并在弯管与直管接槎处加钉一个卡子。安装下节水落管时套入上节水落管的长度应不少于4cm,加一半圆卡子用螺丝拧紧;最下面一节管子要待勒脚、散水做完后才能安装,主管距散水面20cm处安装45度弯嘴一个,弯嘴与水落管之间接头必须焊接;水落管经过带形线脚、檐口等墙面突出部位处宜用直管,线脚、檐口等处应预留缺口或孔洞;如必须采用弯管绕过时,弯管的弯折角应为钝角。
4, pipe installation: installation of water pipe with the outer eaves plastering rack from up and down, first in the drop mouth hanger line fall out straight, with steel chisel on the wall eye, in line with the cement mortar into the card iron foot, 1.2m one of the card space, 2cm wall surface, after the cement mortar to reach strength and then install the water pipe When a horse has a leg bent, it must be pressed into the mouth for 5 to 6cm, and a clip is added to the joint between the elbow and the straight pipe. The length of the installation of the lower water pipe should not be less than 4cm, and a half circle clip is screwed with screws; the bottom pipe is to be installed after the foot and water is finished. The head is installed at the 45 degree bend of the water surface at 20cm, and the joint between the bend and the water pipe must be welded; the water pipe passes through the shape and foot. It is appropriate to use a straight pipe in the outburst of the eaves and other wall surfaces, and the notch or hole should be reserved for the line feet and eaves. If the elbow must be taken around, the bending angle of the elbow should be a passive angle.
