Definitions

  • the present invention relates to the field of the construction industry and public works, in particular the field of the manufacture of construction equipment including formwork devices in the form of bannock and the object is a form including a closure device of the pinways.
  • the wall formwork is generally carried out by means of panels which are constituted by a formwork surface proper, by ground support means and verticality adjustment and by means of assembling adjoining banches them and which are further provided with ancillary safety devices, such as traffic platforms, the various components being assembled by means of bolts or pins.
  • These panels are interconnected by means of through pins based on the substructure of the panels, at the posts and through the corresponding passages in the form of holes of the formwork skins, and by means of end assembly wall or sail and by means of high assembly consisting of pins squeezing the boards over their upper edge.
  • Such an embodiment makes it possible to respond satisfactorily to the problems of clamping the boards in the service position.
  • the through holes of these pins must be plugged to prevent concrete flow through the formwork face and to ensure a correct wall finish or sail sunk at these holes.
  • Closures of passages in banches are notably known by FR-A-2,574,840 and by DE-U-87 10 675 .
  • Such closures consist of sockets flush mounted on a panel and having one or more lips that can move apart elastically for the passage of a pin and resuming the closed position when the pin is disengaged. In this case, no means of maneuver and forced holding of the closure element are provided.
  • Closures of this type make it possible, of course, to prevent the penetration of the concrete in the rest position, but are not dadpted at the closing of modern banister pin passages, which are likely to be subjected to strong pressure on them. wall, pressures that would not resist these closures.
  • These have, indeed, a deformable constitution and it is obvious that a high pressure inside the formwork will have the effect of deforming them in the direction of an opening, so that a passage will be released for the concrete.
  • these documents provide for the establishment of specific plugs of the type mentioned above.
  • the present invention aims to overcome these disadvantages by providing a form including a device for plugging the pin passages for a quick and easy implementation and avoiding any risk of loss.
  • the herehe which comprises a device for plugging the pin passages provided for each pin, to the right of a support post of a hencehe in the formante skin, is characterized in that said closure device is constituted, for each spindle passage, by a closure member mounted on an operating rod and by a receiving sleeve of the closure element, in the closed position of the spindle passage, mounted coaxially with said spindle passage, on the back side of the formant skin of the sayhe.
  • FIG. 1 and 2 appended drawings show a part of box 1 to the right of a shoring post 2, this box 1 being provided with passages of pins 3 in its skin formwork 4.
  • these spindle passages 3, of which only one is represented on the figures 1 and 2 must be plugged by means of a device 5 for plugging the pin passages 3, when clamping the trusses by means of pins is not necessary.
  • the device 5 for plugging the pin passages 3 is constituted, for each pin passage 3, by a plugging element 6 mounted on an operating rod 7 and by a socket 8 for receiving the element. capping 6, in the closed position of the spindle passage 3, mounted coaxially with said spindle passage 3, on the rear face of the formwork skin 4 of the panel 1.
  • the bushing 8 for receiving the sealing element 6 is mounted on the rear face of the casing skin 4 of the casing 3 by means of a centering flange 8 'cooperating with a corresponding hole 3' of the spindle passage. 3 and comprises, on the one hand, a frustoconical guide 81 extending from its face opposite to that comprising the centering flange 8 'to a stop 81' delimiting with the free end of the centering flange 8 a coaxial bore 82 and, on the other hand, in the end opposite to that comprising the centering flange 8 ', a locking device in position of the closure element 6.
  • the locking device in position of the closure element 6 is formed in the form of bayonet grooves 83 formed in the corresponding edge of the sleeve 8.
  • the blocking element 6, mounted on the operating rod 7, has, on the one hand, an end portion 61 in the form of a cylindrical plug intended to cooperate, in the operating position, with the coaxial bore 82 between the abutment 81 'of the frustoconical guide 81 and the centering flange 8' of the receiving sleeve 8 and provided with a shoulder 61 'bearing, in a position of service, on said stop 81 'of the frustoconical guide 81 and, secondly, a portion 62 cooperating with the actuating rod 7, and provided with tabs projecting radially and cooperating, in the operating position, with the bayonet grooves 83 forming the locking device in position of the closure member 6 of said receiving sleeve 8.
  • the length of the end portion engaging in the coaxial bore 82 is equal to that of this coaxial bore 82 between the bearing face of the stop 81 'and the free end of the centering flange 8' of the receiving s
  • the invention allows a commissioning of the device from the back of the panel 1, whatever the position of the latter.
  • the closure member 6 is simply inserted, by its end portion 61 through the frustoconical guide 81 of the receiving sleeve 8, and the coaxial drilling 82, to come into contact with the stop 81 'with its shoulder 61'.
  • the radial lugs 63 of the portion 62 intended to cooperate with the actuating rod 7 are then inserted, by rotation by means of the operating rod 7, into the bayonet grooves 83, for holding the assembly in position.
  • the blocking element 6 is mounted on the operating rod 7 by means of a hollow cylindrical sleeve 61 ", provided coaxially and on the side opposite its end portion 61 and connected to said operating rod 7, by bonding, by welding or by frettage.
  • the portion 62 intended to cooperate with the actuating rod 7 and provided with radially projecting lugs 63 is advantageously in the form of a threaded socket carrying the radial lugs 63 and is screwed by its tapping on a corresponding thread of the hollow cylindrical sleeve 61 "of the closure member 6.
  • the closure element 6 is inserted, by means of the operating rod 7, first in the frustoconical guide 81 of the sleeve 8, then in the coaxial bore 82 until its shoulder 61 'comes into contact with the stop 81'. In this position, the tabs 63 of the part 62, which cooperates with the operating rod 7, penetrate into the bayonet grooves 83 of the sleeve 8.
  • a rotation of the operating rod 7 then makes it possible to bring these lugs 63 into their locking position. Due to the fitting of the threaded sleeve-shaped portion 62 on a corresponding thread of the hollow cylindrical sleeve 61 "of the sealing member 6, it is then possible, by continuing the rotational movement of the operating rod 7, to move the closure member 6 in translation to apply it forcefully to the stop 81 ', by its shoulder 61', the tabs 63 of the portion 62 being pressed fully in the bayonet grooves 83 of the sleeve 8, so that the free end of the portion 61 is flush with the form skin 4.
  • the operating rod 7 in order to be able to easily maneuver the operating rod 7, the latter is advantageously provided at its free end with an operating handle 7 ', this handle 7' being able to be provided, in addition, a radial bore 71 'passing through a not shown operating rod.
  • this handle 7' being able to be provided, in addition, a radial bore 71 'passing through a not shown operating rod.
  • the operating rod 7 may also be provided with a means 9 for retaining the assembly, which forms the rod 7 with the closure element 6, on the panel 1, this means being preferably constituted in the form of a plate freely rotatably mounted on the end of the actuating rod 7, under the operating handle 7 ', this plate can be connected to the form 1 by means of a cable or a chain (not shown).
  • the cable or the chain is connected to the wall 1 by means of a plate 10 integrated in the shoring pole 2 and provided, on the one hand, with a notch 10 'or an eyelet of receiving an end of the cable or the chain and, secondly, a recess 10 "housing of the operating rod 7 in the non-use position, said operating rod 7 then resting on said plate 10 by through the platen forming the retaining means 9.
  • This retaining means 9 avoids any risk of loss of the closure member 6, particularly when not in the service position .
