Embodiment 1

[0016] Example 1: Refer to the attached Figure 1-6 . A prestressed concrete pipe pile butt joint component includes a prestressed concrete pipe pile butt joint end plate. The prestressed concrete pipe pile butt joint end plate is composed of a boss-shaped flange end plate 6, a ring groove-shaped clamping end plate 3, and two A half-annular boss lock ring 4 and bolts 5 are formed; the end face of the boss-shaped flange end plate 6 coincides with the end face of the ring groove-shaped clamping end plate 3, and the boss 401 is inserted into the ring of the two half-annular boss lock ring 4 The groove-shaped clamping end plate 3 and the surrounding of the boss-shaped flange end plate 6 are connected with the bolt threaded holes 403 on the convex pillars of the two semi-annular boss lock rings 4 through a plurality of bolts 5. The thickness 303 of the upper wall of the ring groove in the ring groove-shaped clamping end plate 3 is greater than the height of the boss post 402 of the...

Embodiment 2

[0017] Example 2: Refer to the attached Figure 7 . On the basis of embodiment 1, a prestressed concrete pipe pile composed of claims 1-7, the boss-shaped flange end plate 6 and the ring groove-shaped clamping end plate 3 are respectively located on the two prestressed concrete pipe piles 1. The end, and the boss-shaped flange end plate 6 and the ring groove-shaped clamping end plate 3 are connected by a steel rod 2. The two ends of the steel rod 2 have a head-shaped structure and are respectively clamped in the head clamping hole 301 of the boss-shaped flange end plate 6 and the ring groove-shaped clamping end plate 3 head clamping hole (601) Inside.

Embodiment 3

[0018] Example 3: Refer to the attached Figure 7 . On the basis of Examples 1 and 2, a butt joint structure between prestressed concrete pipe piles constituted by claim 8. The boss-shaped flange end plate 6 of the upper section of the prestressed concrete pipe pile 1 and the lower section Stressed concrete pipe pile 1 ring groove-shaped clamping end plate 3 faces coincide, two semi-annular boss lock ring 4 middle boss 401 is inserted into the ring groove of ring groove-shaped clamping end plate 3 and boss-shaped flange end plate 6 is connected with bolt threaded holes 403 on the convex pillars of the two semi-annular boss lock rings 4 by a plurality of bolts 5 around the circumference.

Abstract

The invention relates to a prestressed concrete pipe pile butt joint construction member and a prestressed concrete pipe pile, wherein the prestressed concrete pipe pile butt joint construction member and the prestressed concrete pipe pile are capable of ensuring small stress transfer after the prestressed concrete pipe pile and the prestressed concrete pipe pile are butt jointed, and capable of preventing the phenomenon of plate-rotting of an end plate of the prestressed concrete pipe pile. The prestressed concrete pipe pile comprises a prestressed concrete pipe pile butt-joint end plate which is composed of a boss-shaped flange end plate, a circular groove-shaped clamping end plate, two semi-circular boss locking rings and bolts. The end face of the boss-shaped flange en plate is matched with the end face of the circular groove-shaped clamping end plate, bosses inside the two semi-circular boss locking rings are inserted into the circular groove-shaped clamping end plate and the periphery of the boss-shaped flange end plate are connected with bolt screw thread holes of the protruding column inside the two semi-circular boss locking rings through a plurality of bolts. The prestressed concrete pipe pile butt joint construction member and the prestressed concrete pipe pile have the advantages of solving the phenomenon of plate-rotting after the welding of the prestressed concrete pipe pile end plates, and ensuring reliable transfer and reliable butt joint of prestress between an upper segment of the pipe pile and the lower segment of the pipe pile.

Description

Technical field [0001] The invention relates to a pre-stressed concrete pipe pile butt joint that can ensure the butt joint between the pre-stressed concrete pipe pile and the pre-stressed concrete pipe pile, can ensure small stress transmission, and can avoid the phenomenon of rotten slabs at the end of the pre-stressed concrete pipe pile Components and prestressed concrete pipe piles belong to the field of prestressed concrete pipe pile end plates and prestressed concrete pipe pile manufacturing. Background technique [0002] CN201276702Y, the name "prefabricated prestressed concrete pipe pile connecting pile structure", includes lower section piles and upper section piles. The ends of the lower section piles and the upper section piles are pile end plates with a number of self-retaining holes, which are characterized by , It also includes pins corresponding to the number of reserved holes, and the pins are inserted into the reserved holes of the lower section pile and the uppe...
