US 2009/0022545 A1 · JOINT FOR REINFORCED CONCRETE PILE SECTIONS

Abstract

The invention relates to providing a stiff pile splice (2a, 2b) between driven reinforced concrete piles (1a, 1b) to join them together end-to-end, with the ends of both reinforced concrete piles (1a, 1b) to be joined having an end surface. The connecting means consist of lock rods (5a, 5b) provided with crosswise holes (6a, 6b), cylindrical lock sockets (7a, 7b) provided with a crosswise through-hole (23) to which tube-like parts (8a, 8b, 9a and 9b) and the locking pins (10a) are attached. A pair of splices consists of two similar splicing pieces. The splicing piece is installed to the end of the concrete pile in connection with casting. In order to reduce the cost of manufacture and materials of the splicing pieces and to achieve reliability in operation, they are made by machining or welding. Preferably, the hole (6) in the lock rod and the hole (19a) of the crosswise tunnel (9) extending through the lock socket have an eccentric disposition relative to each other.

Dependent claims

A joint for a concrete pile section comprising:

a first end plate for connecting to the concrete pile;
a plurality of spaced apart lock rods extending substantially perpendicular to the first end plate;
a plurality of spaced apart lock sockets extending substantially perpendicular to the first end plate, wherein each of the plurality of lock sockets has a cavity-forming sleeve with a shoulder portion cut into at least part of the end of the sleeve and axially-aligned crosswise through-holes on opposite walls of the sleeve, wherein the shoulder portion attaches to the first end plate such that the axis of the crosswise through-holes is eccentrically offset in the socket extending direction relative to a mating lock rod inserted in the cavity;
and
at least one pin-receiving member interconnected between the crosswise through-holes of at least two of the plurality of lock sockets, wherein the member extends substantially across the first end plate.

A joint for a concrete pile section comprising:

a plurality of spaced apart lock rods attached to a first end plate and extending substantially perpendicular to the end plate, wherein at least two of the lock rods each comprise a crosswise through-hole having an axis substantially parallel to the plane of the first end plate and substantially co-axial to each other;
a plurality of spaced apart lock sockets extending from the first end plate in a substantially opposite direction from the plurality of lock rods, wherein at least two of the lock sockets each comprise a cavity-forming sleeve with a shoulder portion cut into at least part of the end of the sleeve and crosswise through-holes through the opposite walls of the sleeve, the through-holes having an axis substantially parallel to the plane of the first end plate and substantially co-axial to each other;
a first pin-receiving portion extending from a first peripheral edge of the first end plate into one of the crosswise through-holes of one of the cavities;
a second pin-receiving portion extending between two crosswise through-holes of the cavities of the at least two lock sockets and substantially axially-aligned with the first pin-receiving portion;
and
a third pin-receiving portion extending from a second peripheral edge of the first end plate into one of the crosswise through-holes of the cavities and substantially axially-aligned with the first and second pin-receiving portions,
wherein the at least two lock rods and the at least two lock sockets are axially-aligned in the socket extending direction with respective mating lock sockets and lock rods on a second end plate, and
wherein the shoulder portion attaches to the first end plate such that the axis of the crosswise through-holes is eccentrically offset in the socket extending direction relative to the lock rods on the second end plate inserted in the cavity.
