A multipurpose reusable support device is provided. The device includes a horizontal support member and a vertical support member connected at an intersecting pivot point to establish a support angle. The horizontal support member and the vertical support member are connected via an adjustable support member such that the device forms a shape substantially similar to a triangle. The adjustable support member may further include an adjustable ratchet configured to adjust the length of the adjustable support member which in turn adjusts the support angle to fit the needs of a user.

The present invention corresponds to a formwork mechanism for casting and molding concrete, comprising a coffer having a sheet and four plates around the sheet perimeter. Each plate has holes arranged on its front face. Also, the formwork mechanism includes a structural element, connected to one of the plates by fixing means. On the other hand, the structural element has lateral perforations that are aligned with the holes of one of the coffer plates. Fixing means pass through the holes and side holes. The structural element may be a beam, a three or four-beam T, and combinations thereof. On the other hand, using several coffers interconnected with structural elements, formworks are constructed for casting flat reticular slabs; and also for curved reticular slabs with greater slab thickness near the beams supporting the slabs in comparison to the span of the slabs.

A holder for supporting a threaded rod for being embedded in concrete, comprising a central portion including a first opening for receiving an end portion of a threaded rod; a ring portion; arm portions connecting the central portion to the ring portion, the arm portions including respective base portions; leg portions attached to the ring portion; and the central portion extending above and below the base portions.

An alignment clamp sub-assembly (402) for connecting and aligning a pair of formwork panels (200) with each other is disclosed. The alignment clamp sub-assembly (402) includes a base component (502) to be disposed on a joint between a first formwork panel (200-1) and a second formwork panel (200-2). The base component (502) includes a first slot (504) formed on atop surface, and a second slot (508) formed on a front surface and adapted to receive a tie rod (406) in a lateral direction. The alignment clamp sub-assembly (402) includes a wedge (512) adapted to be received in a vertical direction in the first slot (504). The wedge (512) is inserted to lock the base component (502) on the joint and form the second slot (508) for receiving the tie rod (406).
