Definitions

  • the subject of the present invention is a device for bringing together and flushing shutters, intended in particular for the production of concrete structures.
  • shuttered concrete which consists of pouring concrete between two formwork panels called “formwork”.
  • the forms have dimensions and in particular lengths and heights which are different depending on the use for which they are intended. They are constituted by a wooden or metal frame which carries on one side a covering which is called “shuttering face", the other side being free.
  • This frame has longitudinal members which extend over at least part of the length of the longitudinal sections by which the panels are to be assembled and cross members constituting spacers connecting the longitudinal members to each other on a part of the transverse sections of the panels.
  • This assembly can be completed by the installation of fishplates or additional stiffening members.
  • formwork which comprises means of assembly on edges which are formed on the one hand by a male part having a conical portion which cooperates with a conical sleeve integral with an edge profile of the formwork and extended by a threaded rod and on the other hand by a female part provided with an internal thread which cooperates with that of the rod.
  • This female part also has a conical part which engages in a conical sleeve fixed in the edge profile of the neighboring panel.
  • the conical part of the male part which is mounted in a protective box, generally has a shoulder preventing the jamming of this part during its tightening.
  • French patent GENDROT FR-A-2,655,679 describes a device for assembling formwork panels making it possible to bring two forms together.
  • This device comprises means for flush with the formwork surface of the panels.
  • This patent does not describe a device for bringing together and flush two formwork making it possible to bring together the formwork simultaneously at the outcrop, which uses two pairs of male and female parts as well as means for bringing together the formwork surfaces for formwork.
  • the device for assembling shuttering panels described in French patent FR-A-2,655,679 consists of parts which, by construction, have tolerances that are too tight and this device therefore wears down when it operates which makes it quickly unusable.
  • the present invention seeks to remedy the drawbacks of the devices currently used by providing a device for bringing together and flushing the formwork, which is of a simple, robust design, easy to implement.
  • the positioning of the forms can be adjusted during their assembly in order to avoid roughness on the concrete.
  • Another advantage of the device according to the invention lies in the fact that it can be placed on the formwork so as to avoid the use of complementary members.
  • Another object is that it is simple to set up and that it allows, without the use of significant tools, the outcrop and the bringing together of the formwork in a single operation.
  • Another object of the present invention lies in the fact that the device allows rapid detachment of the two panels ensuring self-cleaning of concrete residues.
  • the various parts have normal wear and tear, which makes it possible to manufacture them with much smaller tolerances.
  • the device according to the invention can therefore still continue to operate, even after long and intensive use, whatever the wear of the formwork surfaces.
  • Another object of the present invention lies in the fact that, whatever the wear of the male and / or female parts, the formwork surfaces will always come to be pressed in a position which ensures an adapted positioning of the two panels which avoids the roughness of the concrete.
  • Another object of the present invention lies in the fact that during the installation of the device, as a function of the intensity of the mechanical action of support exerted, a corresponding plating is generated on the reference surfaces, which increases the adjustment as needed.
  • Another object of the present invention lies in the fact that the device consists of robust male and female parts, of a simple design which allows mass production at low cost. In addition, these parts are compact and in reduced number, which facilitates their use on the site and reduces the cost of the operation.
  • Figure 1 is a schematic view which illustrates two formwork panels assembled using a device according to the invention.
  • Figure 2 is a schematic view showing a female part.
  • Figure 3 is a schematic view illustrating a male part.
  • Figures 4 to 6 are schematic sectional views which illustrate the kinematics of the establishment and removal of the device according to the invention.
  • the present invention relates to a device for bringing together and outcropping of formwork intended in particular for the production of concrete structures.
  • Each panel (1) comprises a frame (2) made of metal, composed of side members (3) and cross members (4) which constitute spacers which connect the side members (3) to each other.
  • a covering (5) constituting a smooth formwork face such as for example a metal plate or any other suitable material is fixed by means of bolts or screws on one side of the frame (2).
  • FIG 2 there is more particularly shown a female part (8) of the device according to the invention.
  • This female part (8) has a body (12) constituted by a U-shaped profile with a shape complementary to that of the edge profiles of the formwork panel.
  • this female part (8) is secured by conventional welding techniques or any other technique suitable for the edge profile of the panel (1) without the need to make specific modifications or layouts on the panel structure.
  • the U-shaped body (12) has a flat central wall (13) and two lateral walls (14, 15) arranged perpendicular to the central wall (13) on either side of a central plane, delimiting housing.
  • the middle wall (13) has at one of its ends (16) a cut-out constituting an oblong opening (17) and, at the other of its ends (18), two inclined guide rails (19, 20) on the and on the other side of a median plane, which extend substantially over the entire length of the wall (13) constituting the flush means (9).
  • Each inclined guide rail (19, 20) is respectively fixed to each lateral face (14, 15) perpendicular to the wall (13) extending to a distance D from the edges (21, 22) in order to delimit an area of tolerance, which constitutes the means (11), intended, after installation and cooperation with complementary members of the male part (7) in the mounted position, for an adjustment of the formwork between them by making up for the existing offset.
  • This correction of the offset thus makes it possible to avoid, when placing the concrete, the roughness of casting, which gives the surface of the concrete a non-smooth appearance.
  • This part (7) comprises a body (23) which also has a U shape complementary to that of the edge profile of the panels and a shape complementary to the body (12) of the female part (8).
  • the body (23) At one of its ends (24), the body (23) has a pin (25), which projects in a vertical plane, and two inclined guide rails (26, 27) which extend, in the vicinity of the end (28) of the body (23), by a spout (29, 30).
  • the other end (31) of the body (23) has a stop (32) which extends perpendicularly between the two inclined guide ramps (26, 27).
  • the male part (7) also comprises a member (33) here of rectangular shape in which is formed a tapped hole (34) passing through it right through, parallel to the bolt in order to cooperate with a threaded rod (35) d 'a tightening bolt (36) constituting the means (10).
  • the parts (7 and 8) are of a simple and robust design and that they do not require the use of complex members produced from long and precise machining.
  • each panel (50, 51) has a device according to the invention, the parts of which are arranged so as to work in opposition.
  • Each panel (50, 51) is placed so as to present their edge facing one another in a position such that the bolts (52, 53) are placed in a head to tail configuration.
  • the targette (52) of the panel (50) can be either a targette fixed directly on the edge of the panel or alternatively as more particularly illustrated in this figure, a targette like that which is placed on the body of the male part (7).
  • the targette (53) of the panel (51) is itself a targette of a male part (7) according to the invention. In this position, the body (23) of the male part (7) and in particular the guide ramp (26, 27) cooperates with the housing formed by the wall (13) and the walls (14, 15), as well as the guide rails (20, 21) of the female part (8).
  • each panel (50, 51) is pressed , which ensures an appropriate positioning thereof.
  • the plating of the reference surfaces is adjusted.
  • this simplicity of bringing together and flush with the formwork surfaces of the panels (50, 51) allows, during the removal by simple loosening of the nut (36), as illustrated in FIG. 6, rapid release of the residues concrete that can be retained, which ensures self-cleaning.
  • the male part (7) remains confined inside the housing of the female part (8).
