  • Patent number: 9339944
    Abstract: A casting guide and a method of making a concrete pile using the casting guide, the casting guide including a casting guide end plate, at least two lock rod forms including a first set of crosswise through-holes, and at least two lock socket forms including a second set of crosswise through-holes. The first and second sets of crosswise through-holes configured to removably receive a casting guide pin extending substantially across the casting guide end plate and interconnecting the crosswise through-holes the lock rod forms or lock socket forms when the casting guide is inside a casting chute.
    Type: Grant

  • Publication number: 20090263189
    Abstract: The invention relates to providing a concrete pile splice between driven reinforced concrete piles to join them together end-to-end, with the ends of both reinforced concrete piles to be joined having an end surface. The joint of each pile includes lock rods provided with pin-receiving holes, cylindrical lock sockets provided with pin-receiving through-holes to which pin-receiving tube-like parts are used to interconnect the lock sockets, and locking pins. A pair of joints forming a splice consists of two similar joint pieces. The joint is installed at the end of the concrete pile during the poured casting process. 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.

  • Publication number: 20090022545
    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.
