Inverted T-shaped prestressed concrete tower crane foundation structure
The invention relates to the technical field of tower crane foundation structures, in particular to an inverted-T-shaped prestressed concrete tower crane foundation structure which comprises prefabricated cross beams and prefabricated longitudinal beams, the prefabricated cross beams and the prefabricated longitudinal beams can be orthogonally connected to form a cross-shaped foundation structure, and the interiors of the prefabricated cross beams and the prefabricated longitudinal beams are fastened by penetrating prestressed anchor cable assemblies; the prefabricated cross beams and the prefabricated longitudinal beams are each of an inverted-T-shaped structure comprising a web and a flange plate integrally connected to the bottom of the web. The pre-stressed anchor cable assembly comprises a linear anchor cable and a curved anchor cable located above the linear anchor cable. According to the method, the assembled precast concrete tower crane foundation is locked through the special curve anchor cables, the foundation fastening effect is achieved, meanwhile, the internal force of the precast concrete beam can be effectively reduced, the condition for guaranteeing the bearing stability is small, and the overall size, weight and manufacturing cost of the precast beam can be further controlled.
本发明涉及塔机基础结构技术领域的一种倒T型预应力混凝土塔机基础结构，包括预制横梁和预制纵梁，预制横梁和预制纵梁可正交连结形成十字基础结构，预制横梁和预制纵梁内部均分别通过穿设预应力锚索组件实现紧固；预制横梁和预制纵梁均为包括腹板以及一体连接于腹板底部的翼缘板的倒T型结构；预应力锚索组件包括直线锚索以及位于直线锚索上方的曲线锚索；本发明通过采用特殊曲线锚索对拼装的预制混凝土塔机基础进行锁固的方式，在起到基础紧固作用的同时，能够有效降低预制混凝土梁的内力，从而保证承载稳定性的条件小，能够进一步控制预制梁的整体尺寸重量和制造成本。
