2018-07-20 09:48:17   来源:杭州摩鼎建材   

钢板天沟安装条件跟方法
Installation conditions and methods of steel plate gutter
1、安装条件
1. Installation conditions
钢板天沟安装前必须具备如下条件:钢结构主体(指梁、柱)已安装调整完毕,所有高强螺栓已全部终拧完毕。有女儿墙的工程,女儿墙柱和相应的墙梁已安装调整结束。钢板天沟已进行场。焊接用的电焊机和焊工已到位。
The steel plate gutter must have the following conditions before installation: the main body of the steel structure (beam and column) has been installed and adjusted, and all the high-strength bolts have been finally screwed off. The parapet wall and the corresponding wall beam have been installed and adjusted to finish the project with parapet walls. The steel plate gutter has been carried out. The welding machine and welder used for welding have been in place.
2、安装
2. Installation
按设计图纸将相应的钢天沟倒运到位后,按天沟的大小和重量,采用吊机吊运或人工上运,将天沟运到指定的安装区域,并即时用电焊将天沟临时连接。待一条天沟材料全部到位后,沿天沟外侧用钢丝拉一条通线,把整条天沟内外二条边全部调整到同一直线上,调整时注意使天沟拼接处的缝隙使之最小,并用电焊进行临时固定,随后用直径3.2mm的焊条将底下水平焊缝和两侧边的直焊缝进行满焊,焊接时须注意焊接质量及控制焊接电流,防止将天沟烧穿而增加不必要的麻烦。天沟底面与柱顶连接处可用断续焊,将天沟底部与钢柱柱顶板进行焊接固定,以增加整体的牢固,当天不能焊完的天沟,可用电焊用上述方法进行临时固定,如条件许可,也可将天沟用钢丝绳同墙梁或天沟托架进行绑扎固定。
When the corresponding steel trench is reversed in accordance with the design drawings, the size and weight of the trench are carried by the crane or manual transport by the crane. The trench is transported to the specified installation area, and the trench is temporarily connected with the electric welding. When all the material is in place, a wire is drawn along the outside of the gutter with a wire, and all the two sides of the inner and outer sides of the gutter are adjusted to the same line. When adjusting, the gap in the junction of the gutter is minimized, and the welding is used for temporary fixation, and then the bottom welds and sides of the bottom are used by the electrode of the diameter 3.2mm. Full welding is carried out on straight weld. Attention should be paid to welding quality and welding current when welding, so as to prevent unnecessary wear and tear caused by burning the gutter. Intermittent welding can be used at the junction of the bottom of the gutter and the top of the column. The bottom of the gutter and the roof of the steel column column can be welded and fixed to increase the firmness of the whole. The sky ditch that can't be welded on the same day can be temporarily fixed by the welding method. If conditions permit, the steel wire rope can also be tied with the wall beam or the gutter bracket.
