Abstract

A formwork system, including a plurality of side formwork elements configured to confront a concrete structure, a horizontal formwork panel configured to support the concrete structure, and at least one working platform, wherein the system is configured to be split in a longitudinal direction and stricken or cycled from the concrete structure in two discrete parts.

First claim

What is claimed is:

1. A formwork system, comprising:
at least one horizontal formwork element configured to support a concrete structure;
a first connection beam having an integrally formed first connection element and being releasably connected to the horizontal formwork element via a first fixation element received by the first connection element; a second connection beam having an integrally formed second connection element and being releasably connected to the horizontal formwork element via a second fixation element received by the second connection element such that, upon disengagement of one of the first fixation element or the second fixation element, the formwork system is configured to split in a longitudinal direction and stricken or cycled from the concrete structure in two or more discrete parts; and
a plurality of main beams configured to support the at least one horizontal formwork element, the first connection beam, and the second connection beam.

2. The formwork system of claim 1 , wherein at least one of the plurality of main beams is releasably connected to at least one of the first connection beam or the second connection beam.

3. The formwork system of claim 1 , further comprising a plurality of jacks fixed to a bridge pier configured to a least partially support the plurality of main beams, wherein the plurality of jacks, upon actuation, cause respective vertical displacement of the plurality of main beams.

4. The formwork system of claim 1 , wherein at least one of the first fixation element or the second fixation element is a bolt.

5. The formwork system of claim 1 , further comprising at least one vertical beam configured to indirectly attach to the concrete structure, and wherein the concrete structure comprises a bridge pier cap.

6. The formwork system of claim 1 , wherein a first part of the two discrete parts comprises the first connection beam and a first main beam of the plurality of main beams.

7. The formwork system of claim 6 , wherein a second part of the two discrete parts comprises at least the horizontal formwork panel, the second connection beam and a second main beam of the plurality of main beams.

8. The formwork system of claim 7 , wherein the first main beam is disposed below the first connection beam and the horizontal formwork element, and the second main beam is disposed below the second connection beam and the horizontal formwork element.

9. A formwork system, comprising:
at least one horizontal formwork element configured to support a concrete structure;
at least one connection beam having an integrally formed connection element and being releasably connected to the at least one horizontal formwork element via a fixation element received by the connection element such that, upon disengagement of the fixation element, the formwork system is configured to split in a longitudinal direction and stricken or cycled from the concrete structure in two or more discrete parts; and
a plurality of main beams configured to support the at least one horizontal formwork element and the at least one connection beam.

10. The formwork system of claim 9 , further comprising a plurality of jacks fixed to a bridge pier configured to a least partially support the plurality of main beams, wherein the plurality of jacks, upon actuation, cause respective vertical displacement of the plurality of main beams.

11. The formwork system of claim 9 , wherein the fixation element is a bolt.

12. The formwork system of claim 9 , further comprising at least one vertical beam configured to indirectly attach to the concrete structure, and wherein the concrete structure comprises a bridge pier cap.

13. The formwork system of claim 9 , wherein the at least one connection beam comprises a plurality of connection beams.

14. The formwork system of claim 13 , wherein at least one of the plurality of main beams is releasably connected to at least one of the plurality of connection beams.

15. The formwork system of claim 13 , wherein a first part of the two discrete parts comprises a first connection beam of the plurality of connection beams and a first main beam of the plurality of main beams.

16. The formwork system of claim 15 , wherein a second part of the two discrete parts comprises at least the horizontal formwork panel, a second connection beam of the plurality of connection beams and a second main beam of the plurality of main beams.

17. The formwork system of claim 16 , wherein the first main beam is disposed below the first connection beam and the horizontal formwork element, and the second main beam is disposed below the second connection beam and the horizontal formwork element.

18. A system, comprising:
a formwork system, including:
at least one horizontal formwork element configured to support a concrete structure,
at least one connection beam having an integrally formed first connection element and being releasably connected to the horizontal formwork element via a fixation element received by the connection element such that, upon disengagement of the fixation element, the formwork system is configured to split in a longitudinal direction and stricken or cycled from the concrete structure in two or more discrete parts, and
a plurality of main beams configured to support the at least one horizontal formwork element and the at least one connection beam; and

a sideform assembly including a plurality of side formwork elements, the side formwork elements and horizontal formwork element defining a volume for receiving poured concrete, the sideform assembly removably engagable with the formwork system.

19. The formwork system of claim 18 , wherein the at least one connection beam comprises a plurality of connection beams.
