External prestress steering structure
The invention relates to the field of testing devices, in particular to an external prestress steering structure. The structure comprises a box girder, an upper flange and a lower flange are arrangedin the box girder; the upper flange is connected with the box girder top plate; the lower flange is connected with the box girder bottom plate; a supporting assembly is connected between the upper flange and the lower flange. The supporting assembly comprises two web member steel pipes, an included angle beta is formed between the two web member steel pipes, one end of each web member steel pipe is connected with the upper flange, the other end of each web member steel pipe is connected with the lower flange, and a steering steel pipe used for penetrating through an external prestressing tendon is buried in the upper flange and/or the lower flange. According to the external prestress steering structure, the load generated when the external prestress beam is steered can be effectively transmitted to the box girder, meanwhile, the self weight of the structure is greatly reduced, the construction speed is high, and overhauling machines and tools and personnel can pass through the structure conveniently.
本发明涉及测试装置领域，特别是一种体外预应力转向构造,包括箱梁，所述箱梁内设置有上翼缘和下翼缘,所述上翼缘与箱梁顶板相连接，所述下翼缘与箱梁底板相连接，所述上翼缘和所述下翼缘之间连接有支撑组件，所述支撑组件包括两个腹杆钢管,两个所述腹杆钢管之间具有夹角β，所述腹杆钢管的一端与上翼缘相连接，另一端与所述下翼缘相连接，所述上翼缘和/或所述下翼缘埋设有用于穿过体外预应力束的转向钢管。本发明的一种体外预应力转向构造，能够把体外预应力束转向时的荷载有效传递给箱梁，同时大大减轻了结构自重，施工速度快，方便检修机具和人员通过。
