Steel-concrete combined tower tube structure system with U-shaped stiffening ribs
The invention discloses a steel-concrete combined tower tube structural system with U-shaped stiffening ribs, and relates to the field of structural engineering. The steel-concrete combined tower tube structural system comprises flat steel plates, longitudinal flanges, transverse flanges, high-strength bolts, prestressed tendons, anchorage devices, the U-shaped stiffening ribs and the like. A flat steel plate and the U-shaped stiffening ribs are welded in a factory; a transverse flange and a longitudinal flange are welded on the periphery of the flat steel plate; concrete is poured into the U-shaped stiffening ribs, and prestressed tendon hole channels are reserved through corrugated pipes. The flat steel plates with the transverse flanges, the longitudinal flanges and the U-shaped stiffening ribs are transported to a site and spliced through the high-strength bolts, after a tower tube is spliced, the prestressed tendons penetrate through reserved holes, tensioning is conducted from a foundation to the top of the tower tube, and finally epoxy resin is poured into tensioning hole channels. According to the steel-concrete combined tower tube structure system with the U-shaped stiffening ribs, the requirements of a fan of 5 MW or above for bearing capacity and rigidity can be met, the material strength in the combined structure can be fully exerted, and a polygonal structural form is adopted, so that machining and transportation are facilitated.
本发明公开了一种带有U型加劲肋的钢‑混凝土组合塔筒结构体系，涉及结构工程领域。该体系包含平钢板、纵向法兰、横向法兰、高强螺栓、预应力筋、锚具、U型加劲肋等。所述的平钢板与U型加劲肋在工厂焊接而成；所述横向法兰与纵向法兰焊接于平钢板四周；所述的U型加劲肋内灌注混凝土，并用波形管预留预应力筋孔道；所述的带有横向法兰、纵向法兰以及U型加劲肋的平钢板运输到现场通过高强螺栓进行拼装，塔筒拼装完成后，在预留孔内贯穿预应力筋，由基础至塔筒顶部进行张拉，最后在张拉孔道内灌注环氧树脂。该结构体系能够满足5MW以上的风机对承载力和刚度的要求，可充分发挥组合结构中的材料强度，采用多边形的结构形式，便于加工和运输。
