The invention relates to a formwork system which comprises formwork elements having opposite formwork interior surfaces, which can be interlinked at a distance to one another by means of formwork ties. Said formwork ties are constituted of a bolt element and two locking elements that are configured so as to be coupled to the bolt elements in the two distal areas thereof facing away from each other and that are adapted to transmit tensile forces from the formwork elements onto the bolt element. The formwork system is characterized in that the locking elements comprise coupling elements for transmitting pressure forces from the formwork elements onto the bolt element.

A wooden lattice girder 1 for construction comprises an upper chord 4 and a lower chord 5, connected to each other by struts 2, having tenons 7 at each ends thereof, wherein the tenons 7 at one end of the struts 2 are glued into mortises 9 on the upper chord 4, running in the longitudinal direction of the upper chord 4, and the tenons 7 at the other end of the struts 2 are glued into mortises 9 on the lower chord 5, running in the longitudinal direction of the lower chord 5. The lateral surfaces 12 of a respective mortise 9 running in the longitudinal direction thereof encompass an acute angle and the surfaces 10 of the tenon 7 glued to said lateral surfaces 12 of said mortise 9 encompass a corresponding acute angle. The mortises 9 are fashioned in the chords 4, 5 using a circular saw and accordingly define rectangular openings in the chords 4, 5 having square corners.

In a rail-guided self-climbing formwork system 10 in the building sector, climbing rails 18 are guided in climbing shoes 24, 26, 34, 36, wherein the climbing rails are integrated into a scaffold unit. The scaffold unit also includes a working platform 12 and a finishing platform 16, which are also attached to the climbing rails 18. Climbing rail extension pieces 20, 22 can be mounted on the free ends of the climbing rails 18 and rigidly attached thereto. The climbing rail extension pieces 20, 22 are shorter in length than the climbing rails 18.

The invention concerns a panel formwork corner system, comprising a) a panel formwork inner corner element (1), with two inner limbs (5, 6) that are connected to each other and arranged at an angle with respect to each other, b) a panel formwork outer corner element (2) with two outer limbs (25, 26) that are rigidly connected to each other and disposed at an angle with respect to each other, c) two rectangular panel formwork elements (3, 4), each being formed with at least one tie hole (13, 14, 15, 16), wherein all tie holes (13, 14, 15, 16) of a panel formwork element (3, 4) are disposed in a common tie hole plane (A), wherein this tie hole plane (A) extends centrally between two parallel lateral outer edges (17, 18, 19, 20) of the rectangular panel formwork element (3, 4) and perpendicularly with respect to the formlining plane (SE), wherein the position of each tie hole (8, 9, 10, 11) of each inner limb (5, 6) with respect to three lateral outer edges (21, 12, 22) of the inner limb (5, 6) corresponds to the position of a tie hole (13, 14, 15, 16) of a panel formwork element (3, 4) with respect to three lateral outer edges (23, 17, 24, 20) of the panel formwork element (3, 4) and vice versa. With the inventive corner system, a panel formwork can be erected with less effort.

A floor table (1) of a concrete mould for producing a concrete floor (2), comprising at least one front (18, 19) and one rear holder (23) for fixing at least one front (11) and at least one rear ligament (12) of a crane harness (9), characterized in that when the floor table (1) is in a disengaged and retracted state underneath a recently hardened concrete floor (2), it is possible to have access to the holders (18, 18 23) which are used to fix the ligaments (11, 12). The inventive floor table can be drawn out from the floor and displaced with less danger to the workers and requiring less effort in comparison with conventional floor tables.

The invention relates to a ceiling formwork system comprising several grid elements, each of which is composed of a plurality of parallel longitudinal beams and at least one transversal beam that can be mounted or placed on vertical supports and extends perpendicular to the longitudinal beams. The longitudinal and transversal beams of the grid elements are rigidly interconnected. Standard grid elements are provided with two transversal beams in the opposite terminal areas of the longitudinal beams while transversal compensating grid elements are fitted with two transversal beams which are offset towards the inside in relation to the standard grid elements.

A turnbuckle device (10) for clamping concrete shell elements (35, 36) comprises stationary claws (14, 15) and pivotable claws (24, 25) which can be clamped with the stationary claws (14, 15) via a wedge (28) on two neighboring concrete shell elements (35, 36) in that the claws (14, 15, 24, 25) engage in profilings on the frame of the concrete shell elements (35, 36). The stationary claws (14, 15) have archings (18) which engage behind transverse struts (34) or longitudinal struts (33) of a concrete shell element (36). The turnbuckle device (10) is displaceably held on the concrete shell element (36) via the archings (18). If the claws (14, 15, 24, 25) are within the concrete shell element (36), the turnbuckle device (10) can be displaced on the concrete shell element (36) in a longitudinal direction of the transverse strut (34 ) only that far that the turnbuckle device (10) does not project over an outer edge (39) of the concrete shell element (36). The archings (18) and the position of the claws (14, 15, 24, 25) ensure that the turnbuckle device (10) is also safely fixed on the concrete shell element (36) if it is removed. The wedge (28) is a clamping means for the turnbuckle device (10) and also an opening and closing means for the pivotable claws (24, 25).

The invention relates to a scaffolding, especially facade scaffolding, comprising vertical poles (11) located one behind the other, preferably in pairs, and interconnected at given vertical intervals by means of cross struts (12). Said vertical poles (11) consist preferably of individual elements (11′) and form carrier frames (43) with said cross struts (12). Base plates (13) are also positioned between the cross struts (12) of neighboring carrier frames (43). Diagonal poles (27) are arranged between at least some of the neighboring vertical poles (11). According to the invention scaffolding of this type is configured in such a way that at least one end of the diagonal poles (27) engages in an aperture (16) provided in the designated vertical pole (11) by means of a hook (15, 15′). Said opening lies at least essentially in the plane defined by the axes (17) of the neighboring vertical poles (11).

The invention relates to a ceiling formwork system comprising several formwork elements, the bottom face of which is provided with supports that can be coupled to heads of vertical props. At least some areas of the cross section of said supports are embodied in a C-shaped manner, with two legs extending from a basic section. One of the legs is designed as a supporting surface that is to rest on a head of a vertical prop while the head of a vertical prop is provided with fixing elements which engage into one respective recess of a supporting surface. Said recess is configured so as to selectively couple the support to the vertical prop in two directions that are offset relative to each other by 90° at the end of the supporting surface which faces away from the basic section.

A locking device (20,21) for an anchor rod (2) of an anchor system of a concrete wall form, has a screw nut element for screwing the anchor rod through a screw thread of the screw nut element. A dome plate can be fastened to a back of a form element (5,6) of the concrete wall form by means of fastening elements (30) and has a spherically shaped plate section with an opening in which the screw nut element is arranged so as to have radial play. The screw nut element has a groove-type radial seat which accommodates the edges of the opening in the spherical plate sections.
