Abstract: A formwork anchor for tight connection of formwork elements comprises a first anchoring portion which can be anchored on a first formwork element, an at least sectionally conical portion, and a second anchoring portion. The at least sectionally conical portion is provided between the first anchoring portion and the second anchoring portion, and an anchoring element provided to be positioned at the second anchoring portion in a certain anchoring position. The anchoring element can be displaced freely in relation to the second anchoring portion in the longitudinal direction thereof and can be fixed by means of engaging means in relation to the second anchoring portion in the longitudinal direction thereof.

Abstract: The aim of the invention is to improve the load-bearing capacity of formwork supports during shock-type stress that is effective especially perpendicular to or at an angle from the longitudinal axis of the support. Said aim is achieved by a formwork support which is made essentially of wood and is provided with a top chord, a bottom chord, and a web that connects the two chords. The web and/or at least one of the chords comprises at least one recess in at least one final area of the support said recess being filled with a filling material that has shock-absorbing properties. The invention also relates to a method for producing such a formwork support.

Abstract: The invention relates to a support for the building industry, comprising a pipe (10), which has an axial profile in at least one end section, which is accessible from the outside when in use. The outside and/or inside diameters and/or the wall thickness in at least one end region of the pipe are enlarged compared to the remainder of the pipe (10). During production of a pipe or support in the building industry, the outside and/or inside diameters and/or the wall thickness is increased in that at least one end section, which is assessable from the outside when in use, compared to the remainder of the pipe and the pipe has an axial profile.

Abstract: A formwork anchor comprises a threaded rod, screwable into a thread formed in a first formwork element, a shiftable and exchangeable cone provided on the threaded rod and a removal element that is connectable with the cone and to which a removal force can be applied to remove the cone from hardened concrete. A method for anchoring formwork elements comprises the steps of screwing a threaded rod of a formwork anchor into a thread that is formed in a first formwork element, connecting a shiftable and exchangeable cone provided on the threaded rod with a removal element and shifting the cone and the removal element relative to the threaded rod in the direction of the first formwork element.
