Corrugated web H-shaped steel beam

TIAN LI / WANG CHUANXIANG

The invention discloses a corrugated web H-shaped steel beam, and belongs to the technical field of building construction tools. The corrugated web H-shaped steel beam comprises an upper wing plate, alower wing plate, a corrugated web, vertical grooves, an upper positioning hole, a lower positioning hole and mounting holes, wherein the upper wing plate and the lower wing plate are fixedly connected to the upper and lower ends of the corrugated web respectively, and the vertical grooves are distributed in two side surfaces of the corrugated web at equal intervals. According to the corrugated web H-shaped steel beam, the staggered vertical grooves are formed in both sides of the corrugated web, so that the friction strength of the side surfaces of the corrugated web can be increased in thecondition that the support strength of the corrugated web is not influenced, and when the steel beam and concrete are poured, the connection firmness is increased; a lifting lug is arranged and has splitting and combining functions, so that the disassembly time of the lifting lug is saved, and the lifting lug can be repeatedly used; and a positioning block and a connecting base are arranged, so that the steel beam and other main beams can be conveniently and rapidly positioned and connected, and the installation efficiency of the steel beam is greatly improved.

本发明公开了一种波纹式腹板H型钢梁，属于建筑施工用具技术领域，钢梁包括上翼板、下翼板、波形腹板、竖槽、上定位孔、下定位孔和安装孔，上翼板和下翼板分别固定连接在波形腹板的上下两端，竖槽等距分布在波形腹板的两个侧面，该波纹式腹板H型钢梁的波形腹板设置的两侧互相错位的竖槽，可以在不影响波形腹板支撑强度的情况下，增加波形腹板侧面的摩擦强度，从而使得钢梁在与混凝土浇灌时，提高了连接牢固性，而且设置的吊耳具有分拆组合的功能，不仅节约了吊耳的拆卸时间，而且使得吊耳可以进行重复使用，并且设置的定位块和连接座便于钢梁与其它主梁进行快速的定位连接，大大的提高了钢梁的安装效率。
