Expansion-type mechanical quick connector of pre-stressed concrete pipe pile
The invention discloses an expansion-type mechanical quick connector of a pre-stressed concrete pipe pile. The expansion-type mechanical quick connector of the pre-stressed concrete pipe pile comprises a connecting shaft (1) of an expansion structure, an upper pipe pile section (20) and a lower pipe pile section (30), wherein a first end (11) of the connecting shaft (1) is connected with an uppersection end plate of the upper pipe pile section in a threaded mode, and a second end of the connecting shaft (1) is provided with an anti-disengagement edge (14) and a core hole (15) and penetrates through a lower section end plate (3) to stretch into the lower pipe pile section (30); a fixing core (32) matched with the core hole (15) in the second end of the connecting shaft is arranged in the lower pipe pile section (30); and the anti-disengagement edge (14) is clamped below the lower section end plate (3). According to the expansion-type mechanical quick connector of the pre-stressed concrete pipe pile, the connecting shaft is of the expansion structure, so that the anti-seismic strength, the anti-crush strength and the tensile strength are high; the requirement for the morphology andclamping precision of the anti-disengagement edge are not high, and the connection effect of the anti-disengagement edge is not affected by certain collisions in the construction process; and the expansion-type mechanical quick connector is simple in structure, easy to install, and high in construction quality.
本发明公开了一种预应力混凝土管桩膨胀式机械快速接头，包括为膨胀结构的连接轴(1)和上、下节管桩(20，30)，连接轴(1)的第一端部(11)与上节管桩的上节端板(2)螺纹连接，第二端部(13)设防脱沿(14)和芯孔(15)，第二端部(13)穿过下节端板(3)伸入下节管桩(30)，下节管桩(30)内设一与连接轴第二端部芯孔(15)相配合的固定芯(32)，防脱沿(14)卡于下节端板(3)的下方。该预应力混凝土管桩膨胀式机械快速接头，其连接轴为膨胀结构，抗震、抗压、抗拉强度大，且对防脱沿的形貌、卡合精度要求不高，施工过程中的一些碰损不会影响其连接作用，该结构简单，易于安装，工程质量高。
