Definitions

  • the invention belongs to the field of construction and building, and more specifically to the production of slabs, concrete floors, beams, formwork, or even traffic decking and materials acceptance. It relates more specifically to a device able to temporarily support at least one element, such as for example a beam allowing the realization of such structures, in particular on a construction site.
  • the laying of prefabricated or non-prefabricated slabs requires the temporary reinforcement of the supports at the load-bearing structure, in this case a wall, a post or a beam, by adding beams under the slabs.
  • the traditional shoring shoes comprise, as already said, a vertical plate, intended to be fixed reversibly against the support structure and in particular the load-bearing wall, in the vicinity of the level of reception of the said beams and, as a corollary, of the slab, leaving traditionally, notwithstanding the vertical stroke of the cylinder rod, little room to allow, after drying of the slab or sealing of the prefabricated element, their removal.
  • these devices require both for their installation and for their removal a minimum vertical displacement, making their implementation more complex and less practical.
  • the objective sought by the present invention is to propose a device of the type in question, of simple handling, both during assembly and disassembly, in particular because of the optimized accessibility of the fastening system, and whose weight of the unit elements components of the device is relatively small.
  • the invention relates to a temporary support device for at least one element entering into the process of producing part of a structure, in other words a shoring shoe, capable of being removably fixed on a load-bearing structure, and in particular a wall, a post, a beam, and intended to support at least said element with a view to producing concrete slabs or pre-slabs, beams, decking, etc.
  • the invention consists, first of all, in proposing such a shoring support in two distinct essential parts, independent of each other, and reversibly attachable to each other, a fixing plate and a console, the height adjustment member of the latter also being able to be independent of said console. In doing so, the weight of the assembly thus formed is reduced, since the various individual elements are also handled separately from one another.
  • the positioning and dismantling of the shoring shoe is facilitated, since also, one proceeds first of all to the fixing of the only plate on the supporting structure considered during the assembly, and said plate is retracted in the absence of the console and the associated actuator during dismantling, with easy access to the fixing hole, the withdrawal of the console being effected by a simple horizontal movement.
  • the figures 1 to 3 therefore illustrate the shoring shoe of the invention.
  • the plate (1) is generally rectangular in shape and has a plane bearing surface (3) against the wall (20).
  • the plate (1) is provided, near its upper end, with a through hole (4), intended to allow the passage of a fixing screw (10), typically a concrete screw, advantageously previously inserted into the wall considered, as will be described later.
  • This through hole (4) advantageously has a particular shape in the form of a lock, and typically a lower zone of circular section, extending by an upper groove, the width of which corresponds to the clearance close to the diameter of the concrete screw (10) considered, this, for the sake of ease of installation of the plate on the one hand, and precision of said installation on the other hand.
  • the face opposite the flat bearing face (3) of the plate (1) has a male member (5, 6, 7), typically of square cross section, and extending perpendicularly by relative to the general plane in which the plate (1) is inscribed.
  • the upper face (5) of the male member is extended by a longitudinal stiffener (9) up to an upper U-shaped zone (26), also acting as a stiffener.
  • the side faces (6) and (7) of the male member are pierced with through slots (8), of typically rectangular section, and advantageously not located at the same level. More specifically, the through light (8) is located in the vicinity of the wall (5) while the opposing light, not visible in the figure, is located at a lower level in service, for a reason which will be described later.
  • the console (2) comprises means for receiving and guiding vertically oriented in service of a height adjustment member, and typically of the manual actuator (13), this means of receiving and guiding typically consisting of a tube ( 12) of circular or square cross-section, intended to receive the rod (13) of said manual jack, said rod being threaded to cooperate with a wing nut (14) for adjusting the height of said jack.
  • the rod (13) receives the means (15) for receiving the beam or beams (22, 23), in this case in the form of a double fork, thus making it possible to receive a beam in a first direction, or two beams in the perpendicular direction.
  • the tube (12) is secured to a female member (11) cooperating with the male member (5, 6, 7) of the plate (1).
  • this female member (11) is of a shape complementary to that of the male member (5, 6, 7) of the plate (1), so as to fit onto the latter, in particular by a simple horizontal displacement of the console in the direction of the plate, when the latter has been fixed against the wall (20).
  • This fitting is also made possible due to the presence of a notch (18) made on the upper face of said male member, allowing the passage on either side of the longitudinal stiffener (9).
  • the free end of said female member (11) constituting a support rim (19) bears against the ad hoc face of the plate (1).
  • This female member (11) of the console (2) also comprises two side faces, which when the plate (1) is assembled to the console (2), extend parallel to the side faces (6) and (7) of the male receiving member emanating from the plate (1).
  • the side faces of the female member (11) are also each provided with a through slot, one of which has been shown on the figures 2 and 3 by reference (17).
  • These through-lights also of rectangular cross-section, are also located at two different levels, like what has been described in relation to the through-lights (8) of the side faces (6) and (7) of the male member for receiving the plate (1).
  • the console (2) When the console (2) is positioned on and against the plate (1), the respective through slots coincide, allowing it to insert a removable key (16), de facto crossing these four through slots simultaneously.
  • the difference in level between the through slots induces that the key (16), when assembling the console on the plate, is inclined, and remains thus by simple gravity, avoiding the addition or the implementation of a additional reversible fastening element, and therefore facilitating the handling of the shoring shoe of the invention and its implementation.
  • the free end of said key is provided with a projection (not shown), intended to prevent the total retraction of said key by cooperation of the projection in question with the side wall (27) of the female member. (11).
  • a projection (not shown), intended to prevent the total retraction of said key by cooperation of the projection in question with the side wall (27) of the female member. (11).
  • the through-light provided within this face or side wall (27) is of smaller size, at least in width, than that of the through-light (8) provided within the side face (6) of the male member for receiving the plate (1).
  • said key (16) is captive, which is useful on construction sites.
  • the concrete screw (10) has a diameter of the order of 14 millimeters, and the groove corresponding to the through hole (4) has a width close to 18 millimeters.
  • the height adjustment range of the cylinder is close to 20 centimeters.
  • a line of horizontality (21) is drawn with a chalk line. Then, the wall in question is drilled at this line (21), according to the desired spacings, in order to set up a plurality of concrete screws (10) considered, taking care to let said screws protrude by about 2 centimeters , that is to say by a distance greater than the thickness of the plate (1).
  • Said plate is then inserted at the level of the concrete screw by the circular portion of the through hole (4), then said plate is allowed to slide through the upper groove until it rests on said concrete screw (10 ).
  • said plate is fixed to the wall (20) by a single and unique fixing screw (10).
  • the shoring shoe is thus mounted, and all that remains is to adjust the fork (15) by acting on the manual cylinder (13) by means of the wing nut (14), this, in a well-known way.
  • the formwork skin, the beams and the shoring shoes should be removed.
  • the fork (15) is lowered by actuating the wing nut (14), inducing de facto the stopping of the support of the slab (24) on in particular the beams (22 and 23).
  • the formwork skin (25), the beams (23) then the beams (22) are removed.
  • the key (16) is then removed, then the console (2) is separated from the plate (1) by a simple horizontal movement, made possible by the arrangement of the respectively male and female members of the plate (1) and of the bracket (2). In doing so, it then becomes extremely simple to unscrew the screw (10) and remove the plate from the wall (20), without being bothered by the console or the cylinder that it comprises.
  • This shoring shoe is therefore particularly suitable for corridor formwork, in order to leave free circulation, for shoring up stair landings, again for free circulation, shoring up the edges of pre-slabs, of prefabricated beams or the shoring of decking or acceptance of materials. It is also extremely beneficial for high-rise shoring.
