Various implementations described herein are directed to a formwork system. In one implementation, the formwork system includes aluminum extrusions and aluminum castings. The aluminum castings and the aluminum extrusions can be assembled by being pressed and riveted together.

The present disclosure provides a combined prefabricated reinforced concrete stair mold and a splicing method. The combined prefabricated reinforced concrete stair mold comprises a bottom mold platform (1), wherein an upper platform module (2), a tread module (3) and a lower platform module (4) which are spliced with one another are sequentially arranged on the upper surface of the bottom mold platform (1), and corner modules (5) are arranged between the upper platform module (2) and the tread module (3) and between the tread module (3) and the lower platform module (4); the tread module (3) comprises a tread upper surface mold (6) and a tread lower surface mold (7); and the tread lower surface mold (7) comprises a plurality of combined templates (8) formed by mutual splicing, and the tread upper surface mold (6) comprises a plurality of tread splicing pieces (9) formed by mutual splicing.

A building assembly configured to assist in the preparation of material such as sand or snow for the subsequent sculpting or formation of an object therefrom. The present invention includes a body that has elements that are releasably secured to create an interior volume for receipt of sand or snow and subsequently be removed to expose the compacted sand or snow. The building assembly of the present invention includes a base member having external wall members surroundably mounted thereto creating the interior volume foe the sand or snow. Disposed within the interior volume are vertical support members that are secured to the bottom of the base member and extend upward therefrom. A top assembly is secured to the upper end of the vertical support members to ensure alignment thereof. The external walls are removable after filling the interior volume with sand or snow providing access to be sculpted.

A one-piece post-tension tendon pocket former includes a pocket section configured to create a pocket in an edge of concrete, a formwork securing mechanism connected to the second end of the pocket section configured to secure the second end of the pocket section to a formwork, and an anchor securing mechanism. The anchor securing mechanism is configured to secure the pocket section to a post-tension tendon anchor with at least one fastener hole and includes an anchor sealing portion and at least one retention tab. The anchor sealing portion is configured to seal the pocket section to the post-tension tendon anchor. Each of the at least one retention tab extends from a side of the pocket section and is configured to be secured in one of the at least one fastener holes for securing the seal between the anchor sealing portion and the post-tension tendon anchor.

A supporting and guiding device for a climbing formwork beam and to such beam, comprising a supporting body to be coupled to a building structure, with which supporting means for the beam are associated, and at least one pair of guiding pins for the beam which can be activated by snap action transversely on opposite sides with respect to the beam and are adapted to be arranged in front of portions thereof.

Disclosed herein is a clamp for interconnecting two components of a support apparatus such as components of a shoring apparatus for concrete forming systems. A clamp member having a moveable jaw is received for pivotal movement in a housing that is secured to one of the components. A plurality of flutes disposed at an angle to the pivot axis of the clamp member are received in coacting recesses in the housing and a proximal cap maintains the desired position of the clamp member within the housing. Axial movement of the clamp member will pivot the swing arm and a coacting, moveable jaw toward a fixed jaw formed in the housing to releasably secure the clamp to the other component.

A method of using a template assembly for locating and retaining a plurality of anchor bolts within a form during a concrete pour. The template assembly includes a rigid metal frame and plurality of anchor bolt retainers affixed to the frame, wherein each anchor bolt includes an anchor bolt engaging surface for locating an associated anchor bolt within predetermined tolerances. The frame can be further configured to provide access to at least 75% of the surface of the pour thereby allowing for finishing of the concrete. A plurality of legs can be connected to the frame for adjusting an elevation of the frame.

A side protector for ceiling formwork. The ceiling formwork comprises at least one formwork element having a frame. The side protector has a railing. Furthermore, the side protector has a pivoting frame. The railing is connected to the pivoting frame. The pivoting frame can be connected indirectly or directly to the frame from the bottom side of the ceiling formwork. The pivoting frame can be pivoted from an installation position into an end position about an axis of rotation (A) in such a way that the ceiling formwork is laterally secured by the railing. Furthermore, a ceiling formwork system, having at least one corresponding side protector and ceiling formwork, is specified. In addition, a method for erecting such a side protector is specified.
