The second axis of extension has a pitch angle relative to the first axis of extension in a vertical direction, the pitch angle being less than 180 degrees. The first and second channels each include head-mounting features, the head-mounting features constructed and arranged to retain an elongated head to the coupler while permitting movement of the elongated head relative to the coupler in the first horizontal direction.

An apparatus for use in construction to assist in the support of suspended concrete during at least a curing phase of the concrete. The apparatus comprises a base member and a support member coupled to the base member and moveable relative to the base member between a first relative position (“first position”) and a second relative position (“second position”). A biasing mechanism is operatively coupled to the support member to bias the support member toward the second position. In use, the support member is positioned to engage and support the suspended concrete and move from the first position toward the second position as the concrete cures and contracts, to maintain substantially continuous support to the concrete during at least a substantial period of the curing phase. In the preferred embodiment the apparatus is configured for use with a support prop.

A mounting unit of a partition mount system that removably secures a sheet of material includes a first portion and a second portion. The first portion has a first end and a second end opposite the first end and a pivot on a lower surface thereof. The second portion has a first end and a second end opposite the first end and is configured to mate with the first portion. The first end of the second portion is wider than the second end of the second portion. The first portion and second portion are configured to secure a sheet of material therebetween.

The invention relates to a method for displacing a ceiling formwork (10) for a nearest concreting section (9), wherein first (11) and second (12) supporting devices for supporting the ceiling formwork (10) are arranged below the nearest concreting section (9). Said supporting devices each have a shuttering position (EP) and a stripping position (AP), wherein the ceiling formwork is raised to a concreting level in the shuttering position (EP) and lowered relative to the concreting level in the stripping position (AP). The first supporting device (11) is moved into the stripping position and the second supporting device is moved into the shuttering position, and a collision protection element (15, 15) is arranged between the second supporting device (12) and an end face (17, 17) of the ceiling formwork (10) when the end face (17, 17) of the ceiling formwork (10) strikes the second supporting device (12) after passing over the first supporting device (11), so that the collision protection element (15, 15) forms a flank (15a) rising in the displacement direction (VR) for guiding the ceiling formwork (10) in the displacement direction (VR). The end face (17, 17) of the ceiling formwork (10) is then liftedguided by the collision protection element (15, 15)to the concreting level so that the ceiling formwork (10) passes over the second supporting device (12).

The invention relates to a supporting device (14, 14, 14, 15, 15, 15) for the construction industry. Said device has a fixing element (14a, 15a) which rests against a side wall (2a) and is fixed at a fixing point (FP) of the side wall (2a). Said device also has a cantilever (14b1, 14b2, 14c; 15b1, 15b2, 15c-15e) which is connected to the fixing element (14a, 15a) and, when the fixing element (14a, 15a) is in the fixed state, projects from the side wall (2a) such that a load element (10) can rest against a bearing point (AP) of a bearing element (14b1, 14b2; 15b1, 15b2) of the cantilever. The load element (10) can now be displaced in a displacement direction (VR) substantially parallel to the side wall (2a) relative to the cantilever and, when the load element (10) rests against the bearing element of the cantilever, the cantilever is coupled to the load element (10) such that a displacement force component acts on the cantilever in the displacement direction (VR) when the load element (10) is displaced, said displacement force component resulting in a torque on the cantilever. The device also comprises an anti-rotation element (16, 16, 17, 17) which is connected to the cantilever. When the load element (10) is displaced, another end of the anti-rotation element should rest against the side wall (2a) in order to counteract the torque.

An apparatus for use in construction to assist in the support of suspended concrete during at least a curing phase of the concrete. The apparatus comprising: a base member, a support member coupled to the base member and moveable relative to the base member between a first relative position (first position) and a second relative position (second position), a biasing mechanism operatively coupled to the support member to bias the support member toward the second position, and a preloading mechanism operatively coupled to the support member to releasably lock the support member in a preloaded position relative to the base member at or proximal to the first position.

A system for laterally supporting a vertical shoring post is provided. The system includes a head and a jaw assembly, the jaw assembly movably mounted to the head, the head configured for selective engagement with a shoring post, and the jaw assembly configured for engagement with a beam that provides lateral support to the shoring post. The head comprises first and second arms that extend in the same general direction and when engaging the shoring post the first and second arms are disposed upon opposite sides of the shoring post. The jaw assembly includes a fixed jaw and a movable jaw, the moving member pivotably connected to the fixed jaw, wherein the fixed jaw and movable jaws are configured to receive an end of the beam therebetween.

A ceiling formwork system having a formwork panel which may be placed on at least one vertical support via a mounting head. The mounting head has an anchoring cross-member which in the mounted state on the vertical support is oriented transverse thereto, the length of the anchoring cross-member corresponding to at least one side length of the ceiling formwork panel to be supported, whereby the anchoring cross-member is respectively affixable at its ends to lateral edges of the ceiling formwork panel.

The invention relates to a lowering system (10) for lowering ceiling formworks (70) during the removal of formworks of a building ceiling, comprising a reciprocating piston (14) and a support base (18), and a locking device, wherein the reciprocating piston (14) is slidably mounted in the support base (18), and can be pushed from an extended working position to a lowered position, and can be locked in the extended position by means of the locking device. The locking device has a pivot bearing and an eccentric lever (16), wherein the eccentric lever (16) is rotatably mounted in the pivot bearing, and the reciprocating piston (14) and the support base (18) are supported against each other in the working position by means of the eccentric lever (16).
