Definitions

  • the present invention relates to a support device boards for formwork on beam.
  • a structure generally consisting of formwork boards arranged on beams forming a mold, to maintain the concrete in place, while waiting for its setting and hardening. Because of the large weight of the concrete, the form boards are usually permanently attached to the joists so that the structure is held securely.
  • the object of the invention is to provide a support device of formwork boards, for securely holding boards on beams, which is removable and can be positioned easily at the desired location.
  • Such a device makes it possible to fix the support fittings supporting the shuttering boards removably at the desired locations on the beams, and to easily build the structure having the shape of the desired concrete structure.
  • the dorsal wall of the fixing means comprises a window and the locking means comprises a cam. positioned above the window, said cam being pivotally mounted relative to the fixing means to be able to bear, through the window, on the holding arm of the fitting and to exert a thrust on the fastening means so as to that the two returns of the fastening means can come to grip the sub-faces of the upper flange of the beam.
  • the use of a cam allows an effective locking and unlocking, very simple to implement, which facilitates the positioning and removal of the fitting for a new use.
  • the fastening means comprises a quadrangular cross section section, made in one piece, having a back wall, two lateral flanks, and two returns leaving between them the longitudinal slot.
  • the window may be formed in the dorsal wall, preferably in a non-emergent way longitudinally.
  • the window if present, is constituted by the space separating the dorsal walls.
  • the connecting means comprises a threaded rod engaged in openings formed vis-à-vis in wings projecting upwardly from the back wall of each element, and a clamping member cooperating with said rod threaded.
  • the cam is preferably pivotally mounted in the longitudinal direction of the fastening means which limits the size of the device.
  • the cam is typically connected to a lever for pivoting and coming the cam bearing on the holding arm, which simplifies the actuation of the cam by a user and allows a quick lock or unlock.
  • the back wall comprises at least one threaded hole and the locking means comprises at least one screw which engages in the or each threaded hole to exert a thrust on the fastening means so that that the returns of the fastening means can come close to the underside of the upper flange of the beam.
  • This embodiment is also simple and quick to implement and makes it possible to change the location of the fitting very easily.
  • the bracket of the bracket comprises two side edges that can be flanked by the upper flange of the beam which allows the centering of the fitting on the beam for quick attachment with the locking member.
  • the support branch of the fitting comprises means for fixing an accessory such as a safety barrier or a strut.
  • the forestay can in particular allow to position a new beam and form for example a new formwork to a higher level.
  • the support branch and the support branch of the support fitting together have an L-shaped shape which makes it possible to form a concrete structure whose side walls delimited by the formwork boards are orthogonal to the main surface of the structure.
  • the figure 1 is a schematic perspective view of the support device applied to a beam according to a first embodiment of the invention
  • the figure 2 is a view similar to the figure 1 , in cross section;
  • the figure 3 is a schematic perspective view of the support device according to a second embodiment of the invention.
  • the figure 4 is a view similar to the figure 3 , in cross section.
  • the support device 1 comprises an L-shaped support fitting 2 comprising a support branch 3 designed to receive a formwork board and a holding branch 4 intended to rest on an upper flange 5 of a beam. 6 in the form of I.
  • the beam 6 on which the support device 1 is capable of being applied has a vertical core 7, an upper wing 5, provided with two sub-faces 8, and a lower wing 9.
  • the holding leg 4 of the fitting 2 comprises two lateral edges 11 which can be positioned on either side of the upper flange 5 of the beam 6 so as to facilitate its centering.
  • the support device 1 also comprises a locking member 12 designed to removably fix the holding branch 4 of the fitting 2 on the upper flange 5 of the beam 6.
  • the locking member 12 comprises firstly fastening means 13.
  • the fastening means consists of a profile 13 whose quadrangular cross section corresponds to the cross section of the beam 6.
  • the profile 13 comprises a dorsal wall 14 and a longitudinal slot 15 lined with two returns 16 opposite to the back wall 14 ( figure 2 ).
  • the profile 13 can thus engage on the upper flange 5 of the beam 6 while being superimposed on the holding arm 4 of the fitting 2.
  • the profile 13 is made in one piece. It comprises a dorsal wall 14, two substantially vertical lateral flanks 20 in the use position, which project from the lateral edges of the back wall 14 downwards, and two returns 16 which project each from the lower end of the dorsal wall 14. a flank 20 in the direction of the opposite side 20, the returns 16 leaving between them the longitudinal slot 15.
  • the locking member 12 also comprises a locking means which bears on the holding arm 4 so as to exert a thrust on the profile 13 so that the returns 16 bordering the longitudinal slot 15 of the profile 13 can come to grip the sub-elements. faces 8 of the upper flange 5 of the beam 6.
  • This locking means consists of a cam 17 pivotally mounted relative to the profile 13 to bear against the holding arm 4 of the fitting 2, through a window 18 formed in the profile 13, so as to exert a thrust on the profile 13.
  • the cam 17 is connected to a lever 19 which makes it possible to actuate the pivoting of the cam 17 so as to exert the thrust on the profile 13 ( figure 1 ).
  • the cam 17 is pivotally mounted in the longitudinal direction of the profile 13 to limit the size of the device 1.
  • the locking means is a screw which engages in a threaded hole formed in the profile 13 in order to exert a thrust on the profile 13 so that the two returns 16, bordering the longitudinal slot 15 of the profile 13, come to grip the sub-faces 8 of the upper flange 5 of the beam 6.
  • the support branch 3 of the support fitting 2 also comprises means for attaching an accessory such as a safety barrier or a strut allowing an assembly with another beam 6 of for example to form a new concrete structure at a higher level.
  • the holding branch 4 of the support fitting 2 is first fitted on the upper flange 5 of the beam 6 so that the support leg 3 is placed where the formwork board is to be maintained.
  • the profile 13 is then slid along the flange 5, following the engagement of the longitudinal slot 15 of the profile 13 at the end of the web of the beam 6, to be superimposed on the branch of 4.
  • the lever 19 of the cam 17 is moved in the direction of the support leg 3 so that the cam 17 bears, through the window 18 formed in the profile 13, against the holding arm 4 of the fitting 2.
  • the lever 19 of the cam 17 is moved towards the holding arm 4 so that the cam 17 releases the pressure exerted against the holding arm 4 through the window 18 of the profile 13.
  • the two returns 16 bordering the longitudinal slot 15 of the section 13 then depart from the sub-faces 8 of the flange 5 of the beam 6, unlocking the attachment of the fitting 2.
  • the profile 13 is then removed by a movement sliding along the wing 5 to the end of the beam 6, thus releasing the fitting 2 for a new use.
  • the fastening means 13 comprises two separate elements 13a, 13b, and a connecting means 21 removable and adjustable of these two distinct elements.
  • Each element 13a, 13b is preferably made in one piece and comprises, in the position of use: a lateral flank 20a, 20b substantially vertical, a dorsal wall 14a, 14b protruding from the upper end of the lateral flank 20a, 20b towards the element 13b, 13a opposite, and a return 16a, 16b protruding from the lower end of the side flank 20a, 20b towards the element 13b, 13a opposite.
  • the connecting means 21 comprises firstly a threaded rod 22 engaged in orifices 23 formed vis-a-vis in wings 24a, 24b protruding upwardly from the back wall 14a, 14b of each element13a, 13b. As illustrated on figures 3 and 4 , the threaded rod 22 is further engaged in the cam 17 and is its transverse pivot axis.
