怎样安装大招牌?

这两天正在做一块长2米多宽1米多的一个招牌单面的我是把面板铆在一个用方管焊接的框上的,发现面板特别是中间部位会扇动本想在架子上再焊接两根方管来固定,但是发现这样就会与灯角接触使灯断路,有哪位高手做过大招牌的像这种情况怎么处理的,本人在此真心请教了.

这个尺寸中间必须加撑的

楼主难道不知道可以先拿东东给它绝缘吗，或者用木方也行啊

我也有过同样的问题,搞得我都不做大屏了.

是啊 ，我是用的槽钢做的边框板的中间，也就是字与字之间的间隙里我用的是小角铁给加固的

槽钢和边框一样厚吗？

学习                                                            .

我用的是泡沫塑料,可以废物利用,而且轻巧绝缘,,O(∩_∩)O~

用3*5的囗型方钢,每个字打一个格子,这样就可以做10米以上的牌子了,我们这里基本上是做大牌子,我过8米*1米的、3米*1米的、6.5米*0.8的弧形的等效果不错.

可以用泡沫板垫在中间的

PVC板或木块，用东西粘住
