Definitions

  • the present invention relates to a set of parts making a system hinge for an access hatch to the connection chambers or civil engineering works, more particularly for access hatches called "de service”.
  • Connection chambers or civil engineering works have the most often an access protected by several hatches carried out by buffers of foundry, usually rectangular, resting side by side in a frame sleeping.
  • One of these so-called “service” hatches comprises pivoting means or hooking and locking means and does not allow the operation of the other so-called “slave” hatches only after its own removal from the sleeping frame.
  • pivoting and / or hooking means are generally based on hinge systems resting on a pivoting bar secured to the frame frame on which the service hatch pivots directly.
  • the invention aims to remedy the drawbacks of the prior art.
  • this result is obtained by a set of parts providing an articulation system for access hatch to the connection or civil engineering works, particularly for the hatch said "service" access hatch, said access hatches consisting of buffers rectangular shape lying side by side in a sleeping frame, said frame being consisting of angles placed in the rebate of a concrete chamber, characterized in that it essentially comprises two sleeves on the periphery inside an angle of the frame in the positioning zone of the service hatch, the two sleeves being intended to be the support of parts added, once assembled capable of cooperating freely with the service hatch to make it swivel.
  • the two sleeves are fixed longitudinally on the inner circumference of the angle of the frame and allowing the passage an attached horizontal axis on which two parts are slidably mounted attached supports, each part of a support comprising on the one hand a tab median whose inner face is supported on the horizontal wing of the angle iron and a lower leg perpendicular to the middle leg whose inner face takes support on the vertical inner wall of the concrete chamber and on the other hand, a upper section substantially perpendicular to the middle leg and extended by a return parallel to the horizontal tab, said upper section being susceptible to cooperate with one of the edges of the service hatch, said edge being provided with a shoulder extending perpendicular to the inner face of said hatch.
  • the sleeping frame (4) is consisting of angles (5), each angle (5) being composed of a horizontal wing (50) and a vertical wing (5b), said angle being arranged in a rebate (6) as a square in a concrete chamber (7).
  • the rebate (6) and the angles (5) are of complementary shape.
  • the set of parts making an articulation system (8) comprises two sleeves (9,10) fixed in the factory or welded in situ by example horizontally longitudinally on the inner periphery (19) one of the angles (5) of the frame (4) at the level of the positioning zone of the service hatch.
  • the distance separating the two ends outer (9a, 10a) of the sleeves (9,10) is less than the length or the width a standard hatch.
  • An attached axis (11) extending horizontally is introduced on the side and others of the two sleeves (9,10).
  • Each support piece (12, 13) has two tabs (14a, 14b), one median (14a) bearing by its inner face on the horizontal wing (5a) of sleeping frame (4) and the other lower (15b) coming to bear by its inner face on the inner vertical wall of the concrete chamber (7).
  • Each support piece (12,13) is further provided with an upper section (15) extending substantially perpendicularly to the middle leg and comprising a return (16) towards the sleeping frame, substantially parallel to the tab median (14a).
  • This upper section (15) thus has a general hook shape.
  • One of the edges (21) of the hatch (1) comprises, parallel to the edge (21), a shoulder (18) perpendicular to the inner face (17) of the hatch (1).
  • the height of the shoulder (18) is substantially equal or slightly less than the minimum distance between the return end (16) of the section upper (15) of the support piece (12,13) and the vertical wing (5a) of the angle iron (5) of the sleeping frame (4).
  • the support part (12, 13) comprises a means of positioning and fixing (22) on the horizontal axis (11) preventing any inadvertent sliding of said part (12,13) when the service hatch (1) is in place in the frame (4).
  • the positioning and fixing means (22) consists of an orifice cylindrical (23) drilled in the support piece (12,13) radially to the axis horizontal (11) and comprising a thread into which a bolt (24) is screwed abutment on the surface of said horizontal axis (11).
  • the set of parts making a hinge system according to the invention can be applied to existing frames as a replacement for example hinge devices used for the service hatches of the prior art.
