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, defining a first connection element, releasably connected to the horizontal formwork element via a first fixation element;
a second connection beam connected to the horizontal formwork element such that, upon disengagement of the first 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 the horizontal formwork element is a formwork panel with a formlining.

3. The formwork system of claim 1 , wherein the plurality of main beams comprises at least a first main beam and a second main beam, wherein the first main beam is disposed below a first connection beam and the horizontal formwork element and a second main beam is disposed below a second connection beam and the horizontal formwork element.

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

5. 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.

6. The formwork system of claim 5 wherein the plurality of jacks, upon actuation, cause respective vertical displacement of the plurality of main beams.

7. The formwork system of claim 6 , wherein actuation is caused at least in part by a gearbox assembly removably engageable with one of the plurality of jacks.

8. The formwork system of claim 1 further comprising at least one working platform.

9. The formwork system of claim 8 , wherein at least one connection beam is configured to releasably attach to the working platform.

10. The formwork system of claim 1 , wherein the first fixation element is one of a T-Bolt or a X-Bolt, and the second fixation element is one of a T-Bolt or a X-Bolt.

11. The formwork system of claim 1 , further comprising a plurality of vertically aligned side formwork panels configured to confront the concrete structure.

12. The formwork system of claim 1 , further comprising at least one vertical beam configured to indirectly attach to the concrete bridge pier cap.

13. The formwork system of claim 1 , wherein the concrete structure comprises a bridge pier cap.

14. The formwork system of claim 13 , wherein the bridge pier cap comprises one of a multi-column cap, a hammerhead, or a straddled cap.

15. 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.

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

17. The formwork system of claim 1 , wherein the first connection beam, the second connection beam, and the horizontal formwork are at approximately a same height relative to a horizontal axis when connected.

18. The formwork system of claim 1 , wherein a longitudinal axis of at least one of the plurality of connection beams and a longitudinal axis of at least one of the plurality of main beams are substantially parallel along the longitudinal direction.

19. The formwork system of claim 1 , wherein an axis in a length direction of the horizontal formwork element and an axis of the connection beams in the longitudinal direction are substantially parallel to each other.
