Pre-stressed concrete compression pipe pile tension connector without end plate and pipe pile
The invention discloses a pre-stressed concrete compression pipe pile tension connector without an end plate. The pre-stressed concrete compression pipe pile tension connector without an end plate comprises an expansion shell, a first sealing cover, an expansion connecting pin and a wedge-shaped part, wherein a through groove penetrating through both ends is formed in the expansion shell, the through groove comprises an extending section and a clamping section, the inner diameter of the clamping section is larger than that of the extending section, a first sleeve is arranged at the end, corresponding to the extending section, of the expansion shell, and an inner thread is arranged on the first sleeve; the first sealing cover is fixed to the end, corresponding to the clamping section, outside the expansion shell, and a first through hole is formed in the first sealing cover; the expansion connecting pin comprises a connecting section and an expansion section, an expansion groove is formed in the expansion section, the expansion groove extends axially from the end part of the expansion part to the connecting section, the expansion section is divided into at least two parts through the expansion groove, and the expansion section extends into the expansion shell; and the wedge-shaped part comprises a head part and a tail part, the outer surface of the wedge-shaped part is graduallyclosed inward from the head part to the tail part, and the wedge-shaped part extends into the expansion section along the expansion groove from the tail part to expand the expansion section. According to the pre-stressed concrete compression pipe pile tension connector without the end plate, materials are saved, the structure is simple, but connection is more reliable, and use is more convenient.
本发明公开了一种预应力混凝土无端板抗压管桩涨拉连接件，包括：膨胀壳，其具有贯穿两端的通槽，通槽包括伸入段和卡接段，所述卡接段的内径大于伸入段的内径，所述膨胀壳对应伸入段的一端设置有第一套筒，第一套筒具有内螺纹；第一封盖，其固定于膨胀壳外对应卡接段的一端，且第一封盖上开设有第一通孔；膨胀连接销，包括连接段和膨胀段，膨胀段上设置有膨胀槽，膨胀槽由膨胀段的端部向连接段方向轴向延伸，膨胀槽将膨胀段分割成至少两部分，所述膨胀段伸入膨胀壳内；楔形件，包括头部和尾部，其外表面由头部至尾部逐渐向内收拢，楔形件由尾部沿膨胀槽伸入膨胀段将膨胀段涨开，本发明节约材料，结构简单，但连接更加可靠，使用更加方便。
