一种大跨距铝合金桥架
摘要：
本发明涉及一种桥架，尤其是一种大跨距铝合金桥架，包括对称设置的侧板，以及固定在两个侧板之间的连接板；所述侧板的底部设有托板，侧板与托板成L型，侧板和托板均为内部中空的矩形框，侧板上设有螺钉孔，螺钉孔位于托板的上方；所述连接板位于托板的上方，连接板的两端设有螺纹孔，连接板通过螺钉固定在侧板的内侧，连接板设有多个，连接板沿侧板的长度方向等间距设置。本发明提供的一种大跨距铝合金桥架结构简单、重量轻、跨距大、耐腐蚀、使用寿命长、安装方便、成本低、适用范围广。
摘要（英）：

The invention relates to a bridge frame, and particularly relates to a long-span aluminum alloy bridge frame comprising symmetrically arranged side plates and connecting plates which are fixed betweenthe two side plates. The bottoms of the side plates are provided with supporting plates. The side plates and the supporting plates form an L shape. The side plates and the supporting plates are hollow rectangular frames. A screw hole is arranged on each side plate, and the screw hole is located above each supporting plate. The connecting plates are positioned above the supporting plates. The twoends of the connecting plates are provided with threaded holes. The connecting plates are fixed on the inner sides of the side plates by screws. There are multiple connecting plates, and the connecting plates are arranged at equal intervals along the length direction of the side plates. The long-span aluminum alloy bridge frame has the advantages of simple structure, light weight, long span, corrosion resistance, long service life, convenient installation, low cost and wide application range.
