End plate structure for prestressed concrete pipe pile
The invention relates to an end plate structure for a prestressed concrete pipe pile. The end plate structure comprises an annular steel plate, wherein a plurality of tensioning steel bar positioning areas and a plurality of tensioning bolt holes are circumferentially and dispersedly distributed in the steel plate, the number of the tensioning bolt holes is consistent with that of the tensioning steel bar positioning areas, the tensioning bolt holes are located between every two tensioning steel bar positioning areas, the tensioning bolt holes do not communicate with the adjacent tensioning steel bar positioning areas, and threads which are matched with tensioning bolts are arranged on the inner walls of the tensioning bolt holes. According to the end plate structure, the tensioning steel bar positioning areas which are used for positioning tensioning steel bars and the tensioning bolt holes which are used for connecting the tensioning bolts do not communicate with each other, so that the integrity and precision of internal threads of the tensioning bolt holes are guaranteed, the tensioning bolts and the tensioning bolt holes can be tightly connected and tensioned, additionally, the contact surfaces of the tensioning bolt holes and the tensioning bolts are strengthened, stress concentration is reduced, tensioning stress is balanced, the quality of an end plate is guaranteed, and the weight and steel consumption of the end plate are reduced.
本发明为一种预应力混凝土管桩用端板结构，包括有圆环形钢板，在钢板上圆周分散布置有多个张拉钢棒定位区域和多个张拉螺栓孔，所述张拉螺栓孔和张拉钢棒定位区域的数量一致，张拉螺栓孔位于两个张拉钢棒定位区域之间，且张拉螺栓孔和相邻的张拉钢棒定位区域互不联通；所述张拉螺栓孔在其内壁设有与拉紧螺栓配合的螺纹。本发明中，用于定位张拉钢棒的张拉钢棒定位区域和用于连接拉紧螺栓的张拉螺栓孔互不联通，保证了张拉螺栓孔内螺纹的完整度和精密度，使拉紧螺栓与张拉螺栓孔之间能够紧密连接拉紧，同时，加强了张拉螺栓孔与拉紧螺栓的接触面，减少应力集中，均衡拉紧应力，保证端板质量，还减轻了端板的重量和钢材耗用量。
