Steel structure beam for municipal road and bridge building construction and construction method thereof

TAN FENGKE / LI PING

The invention relates to the technical field of steel structure beams, in particular to a steel structure beam for municipal road and bridge building construction and a construction method thereof. The steel structure beam for municipal road and bridge building construction comprises a cross beam and two vertical beams, and the two vertical beams are detachably connected with the two ends of the cross beam correspondingly and located below the cross beam; each vertical beam comprises a lower mounting plate, a first rod body and a side plate, each cross beam comprises a second rod body, a clamping plate, a first sealing gasket, a guide rail and an upper mounting plate, screws are hidden below the cross beams through the upper mounting plates, so that the screws are not prone to making contact with rainwater, gaps between the cross beams and the side plates are blocked through the first sealing gaskets, rainwater is prevented from entering the peripheries of the screws, and the service life of the screws is prolonged. And the screw is prevented from being eroded.

本发明涉及钢结构梁技术领域，具体涉及一种市政路桥建筑施工用钢结构梁及其施工方法；市政路桥建筑施工用钢结构梁包括横梁和竖梁，竖梁的数量为两个，两个竖梁分别与横梁的两端拆卸连接，并均位于横梁的下方；每个竖梁均包括下安装板、第一杆体和侧板，横梁包括第二杆体、卡接板、第一密封垫、导向轨和上安装板，通过上安装板，将螺钉隐藏于横梁的下方，使得螺钉不易接触雨水，通过设置第一密封垫，将横梁和侧板的间隙堵塞，防止雨水浸入螺钉周围，使得螺钉不受侵蚀。
