Supporting and guiding device for a climbing formwork beam and such beam
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.
1. A supporting and guiding device for a climbing formwork beam, which comprises a supporting body to be coupled to a building structure, with which supporting means for said beam are associated, said device comprising at least one pair of guiding pins for said beam which can be activated by snap action transversely on opposite sides with respect to said beam and are adapted to be arranged in front of portions thereof, wherein said supporting body comprises two opposite lateral plate portions, which are adapted to laterally delimit said beam, each one supporting externally at least one guiding pin, at which it is perforated, with snap-acting activation means, wherein said snap-acting activation means comprise, for each pin:
a receptacle for said pin, inside which it is adapted to slide in order to protrude from a respective lateral plate portion toward said beam,
a helical spring, which is wound around said pin inside said receptacle,
a handle on the outside of said receptacle, on an extension of said pin,
a slot on a wall of said receptacle for the insertion of a dowel which extends at right angles from said pin at the end of said helical spring that is directed toward the respective said wall.
2. The device according to claim 1 , wherein said supporting body comprises:
a vertical plate to be integral with said building structure,
a pair of plates which are arranged in a mirror-symmetrical and parallel fashion, extending from said vertical plate,
a C-shaped metal sheet, in front of said pair of plates, which is provided with a central portion and two opposite lateral portions for at least partial containment of said beam.
3. The device according to claim 1 , further comprising a C-shaped metal sheet, in front of a pair of plates of the supporting body, wherein said supporting means for said beam comprise a pair of parallel and symmetrical hooks which are adapted to support said beam by at least one cylindrical portion thereof which is transverse to its longitudinal direction of extension, said pair of hooks being rotatable about a bolt which passes transversely through a pair of plates and protruding between lateral plate portions from a window in a central portion of said C-shaped metal sheet.
4. The device according to claim 3 , further comprising a fixed plate which is interposed between said pair of hooks and is provided with a hole corresponding to cavities of said pair of hooks.
5. The device according to claim 2 , provided with a coupling seat for coupling to said beam which is defined by said C-shaped metal sheet, said beam comprising:
a pair of longitudinally extended profiled elements that are substantially C-shaped in cross-section, which are connected by means of bolts with openings toward the outside and spaced apart by at least one tubular spacer with a rectangular cross-section which is installed in a first half of a core of said beam,
pairs of hollow cylindrical elements, in a second half of the core of said beam, toward said device, which are arranged so as to be aligned and spaced apart, each one passing transversely, in a corresponding hole, through a core of a respective profiled element, and are adapted to rest on said pair of hooks.
6. A supporting and guiding device for a climbing formwork beam, which comprises:
a supporting body to be coupled to a building structure, with which supporting means for said beam are associated, said device comprising at least one pair of guiding pins for said beam which can be activated by snap action transversely on opposite sides with respect to said beam and are adapted to be arranged in front of portions thereof; and
a C-shaped metal sheet, in front of a pair of plates of the supporting body, wherein said supporting means for said beam comprise a pair of parallel and symmetrical hooks which are adapted to support said beam by at least one cylindrical portion thereof which is transverse to its longitudinal direction of extension, said pair of hooks being rotatable about a bolt which passes transversely through a pair of plates and protruding between lateral plate portions from a window in a central portion of said C-shaped metal sheet.
