[0002] The existing bridge box girder components are connected and fixed by four spliced ​​templates, and then poured inside to form the bridge box girder columns. The disadvantage of the existing bridge box girder components is that since the four corners of the bridge box are provided with bevels, the effect of connecting and fixing the spliced ​​templates to each other is poor when they are connected. And when this type of template is connected, it is impossible to perform sliding adjustment to change the distance between each other to adjust it to a suitable state. It is precisely because of the existence of the above-mentioned shortcomings that the existing bridge box girder components are very inconvenient when people actually use them. Utility Model Content
