Definitions

  • the present invention relates to a security door, which it is difficult to demolish. It is made of a metal sheet, preferably of aluminum, and a metal sheet profile, preferably of steel, which is fastened to the rear face of said metal sheet and functioning as a door frame.
  • the metal sheet profile ordina ⁇ rily is a seat for hinges and locks.
  • the security door often also comprises a second metal sheet on the rear face of the door.
  • the space between the two sheets and the metal sheet profile preferably is filled with a heat insulating material, e.g. steel wool.
  • Doors which it is difficult to demolish and are made of a sheet of a first metal and a sheet profile frame of a second metal, are known in the art.
  • the binding agents which have been used so far , to join the sheet and the sheet profile, are either solely mechanical means or solely welding seams or a combination of these binding agents.
  • Welding seams as binding agents usually are considered to be superior to mech ⁇ anical binding agents, polymeric binders etc.
  • cracks easily develop in the welding seams due to the different coef ⁇ ficients of expansion of the metals. Accordingly, such wel ⁇ ding seams are characterized by inferior strength and usually are unsuitable in security doors.
  • the object of the present invention is to be able to use welding seams as binding agents, when producing a secu ⁇ rity door by joining a sheet of a first metal and a sheet profile frame, which is placed behind said sheet and is made of a second metal, without subsequent cracking of the welding seams.
  • This object is attained in accordance with the present inven ⁇ tion by applying strips of a first metal, namely the metallic material, of which the very door sheet is made, to and along the sheet profile frame and welding them to the sheet, and by joining said strips and said sheet profile frame by means of mechanical joining agents, in order to produce a security door.
  • a first metal namely the metallic material, of which the very door sheet is made
  • a second sheet is fastened to said sheet profile frame as the rear face of the security door, e.g. by means of a polymeric bin- der, a heat insulating material preferably being introduced into the space defined by said two sheets and said sheet profile frame.
  • the present invention relates to a security door. It comprises a sheet of a first metal, e.g. aluminum, having a front face and a rear face. It comprises also a sheet pro ⁇ file frame of a second metal, e.g. steel.
  • the sheet profile frame is fastened to the edges of the rear face of said sheet. It is utilized i. a. as a seat for henges and locks.
  • the characterizing feature of the security door of the present invention is that strips of said first metal are welded to the rear face of said metal sheet and that said sheet profile frame is fastened ot said metal strips by means of bolts or equivalent mechanical binding agents.
  • a second sheet preferably made of said first metal, is fastened to said sheet profile frame as the rear face of the security door, e.g. by means of a polymeric binder. Consequently, a space defined by the two.sheets and the sheet profile frame is obtained and it is preferably filled with a heat insulating material, such as steel wool.
  • Strips 3 of aluminum are welded to the rear face of the outer aluminum sheet 1 of the door by means of a welding seam 4, along all four edges of sheet 1.
  • a profile frame 2 of steel sheet is fastened to said strips 3 and the rear face of sheet 1 by means of bolts 5.
  • a sheet 6 of aluminum is fastened to said profile frame 2 by means of a polymeric binder.
  • the space, which is defined by said two sheets 1 and 6 respectively and said profile frame 2 along the edges of the sheets, is filled with a heat insulating material 7.
  • a second profile frame 8 of steel plate is attached to wall 9 and functions as a door case.
  • a hinge 11 is fastened to said profile frame 2 as well as to door case 10, which is attached to wall 12.
