  • the present invention is intended for a plasterboard panel for access to a compartment of the type comprising a first plasterboard sheet having a first flat surface and a second flat surface opposite the first.
  • This first plasterboard sheet having an opening extending between the first and the second flat surfaces, comprises a first outer zone, delimiting the opening, which extends at least partly in the same plane as the first flat surface.
  • the plasterboard panel also comprises a second plasterboard sheet having a first flat surface and a second flat surface opposite the first, forming a door which can be connected to the opening in the first sheet.
  • the second plasterboard sheet comprises a second outer zone delimiting the door.
  • the plasterboard panel is equipped with holding means for stably connecting the door to the opening, for a door closed configuration, and for at least partly removing the door from the opening, for a door open configuration.
  • plasterboard panels are normally used to allow access to a compartment by removing or moving the door formed by the second sheet.
  • the compartment which may for example be a cavity between two walls, there may be any device, such as an electrical panel, a local vent, and other devices, which requires periodic or impromptu adjustments, repairs or other operations.
  • any device such as an electrical panel, a local vent, and other devices, which requires periodic or impromptu adjustments, repairs or other operations.
  • the prior art includes a plurality of different holding means, to allow door outward opening.
  • access panels are known in which the door and the first sheet are joined together by hinges located on external portions of the panel, that is to say, on portions of the panel which, when panel installation is complete, are not facing the compartment.
  • the prior art panels for access to a' compartment allow surface finishing machining which integrates very well with the walls forming the compartment and on which the access panel is installed.
  • access panels which have stop elements for the door.
  • the stop elements are located on an internal portion of the first sheet, that is to say on the surface of the first sheet directly facing the compartment, so that, when it is in the closed position, the door rests against the stop elements, remaining in a predetermined position.
  • the prior art includes a plurality of solutions for joining the edges of the door and the edges of the opening in the first sheet.
  • said plurality of solutions may be traced back to a single general solution.
  • said general solution involves the closing doors having edges perpendicular to the plane formed by the sheet which forms the door itself. These edges correspond to opening edges perpendicular to the first sheet, that is to say, to the sheet in which the opening is made.
  • the main technical need of the present invention is to propose a plasterboard panel for access to a compartment which is free of the above-mentioned disadvantages.
  • the aim of the present invention is to provide a plasterboard panel for access to a compartment without gaps between the door and the opening.
