这个世界上任何奇迹的产生都是经过千辛万苦的努力而得的,首先承认自己的平凡,然后用千百倍的努力来弥补平凡。小编又来分享新知识了!大家应该都见过膜结构停车棚吧,下面小编为大家简单介绍一下膜结构停车棚的钢材加工过程吧。
Any miracle in the world comes through painstaking efforts. First admit your ordinary, and then make up for it with thousands of times of efforts. Xiaobian has come to share new knowledge again! Everyone should have seen the membrane structure parking shed. Let's briefly introduce the steel processing process of the membrane structure parking shed.
1、下料:资料经抛丸除锈后在相贯切开机上下料,并整理切断处腐渣,预备拼接运用。切开后的杆件均要有坡口。对加强节点处的资料,除按长度切开外,延轴线方向切开,以便于装置。
1. Blanking: after shot blasting and derusting, the materials shall be loaded and unloaded at the intersecting cutting machine, and the rotten slag at the cutting place shall be sorted out for splicing. All cut bars shall be provided with grooves. For the data at the strengthening node, in addition to cutting according to the length, it shall be cut along the axis to facilitate the installation.
2、放样:放样要严厉按图纸进行,放样时应注意,放样是在已预备的胎具基面上进行。
2. Setting out: setting out shall be carried out in strict accordance with the drawings. During setting out, it shall be noted that setting out is carried out on the prepared mold base.
3、胎具预备:胎具由T=16mm厚的钢板构成,宽度与钢管宽度般配,为节省钢板,两行钢板可用槽钢支撑连为一体。组拼弧管需求钢管管径足够大,壁厚有12mm、10mm等。焊缝钝边空隙为2~4mm,坡口视点为40度,对接处不管等截面还是变截面均要衬管。施焊时要严厉依照焊接技能进行。每焊一道都要把焊道整理洁净,以确保焊缝质量。
3. Preparation of mould: the mould is composed of T = 16mm thick steel plate, and the width matches the width of steel pipe. In order to save steel plate, the two rows of steel plates can be connected by channel steel support. The pipe diameter of steel pipe required for arc welding pipe assembly is large enough, and the wall thickness is 12mm, 10mm, etc. The gap of the blunt edge of the weld is 2 ~ 4mm, the angle of view of the groove is 40 degrees, and the butt joint shall be lined regardless of equal section or variable section. Welding shall be carried out in strict accordance with welding skills. Each welding pass shall be cleaned to ensure the weld quality.
4、点固焊:点固支管前,把放样的节点转移到上下弦杆的外表,并按杆件的编号进行点固。点固焊通常是从中间向两头拓展。点固焊间距在50~100mm左右,焊点长度为30mm。
4. Spot welding: before spot welding the branch pipe, transfer the lofted node to the surface of the upper and lower chords, and conduct spot welding according to the number of members. Spot welding is usually extended from the middle to both ends. The spacing of spot welding is about 50 ~ 100mm, and the length of welding spot is 30mm.
5、焊接:焊接时要严厉依照焊接技能规范履行。相贯处和对接处打底应尽量选用CO2气体维护焊,面层可选用手艺焊。
5. Welding: welding shall be performed in strict accordance with welding skill specifications. CO2 gas maintenance welding shall be selected as far as possible for priming at the intersection and butt joint, and craft welding can be selected for the surface layer.
6、焊缝查看:一切对接焊缝按焊缝进行查看,需求开坡口的角焊缝也要进行查看,查看时除查看焊缝外观外,还要进行超声波查看,如发现焊缝不合格,应进行返修。
6. Weld inspection: all butt welds shall be inspected according to the weld, and the fillet welds requiring beveling shall also be inspected. In addition to the weld appearance, ultrasonic inspection shall also be conducted. If the weld is found to be unqualified, it shall be repaired.
7、工地拼接:工地拼接时拼接处要加衬管,并要通过支撑使整个桁架找平,借助手拉葫芦等东西使焊缝处契合图纸需求后再进行点固焊,然后正式施焊。支撑要有必定高度,以便于全.方位焊接。
7. Site splicing: during site splicing, a lining pipe shall be added at the splicing place, and the whole truss shall be leveled through support. The spot welding shall be carried out after the assistant chain block and other things are used to make the weld meet the requirements of the drawing, and then the welding shall be formally carried out. The support shall have a certain height to facilitate omni-directional welding.
