Definitions

  • the invention relates to a frame for forming covers at floor openings, which is designed to accommodate one or more adjacent lids or grids and is composed of a plurality of frame parts provided with a frame foot and a frame wall, which are connected to one another by a screw connection to form the frame .
  • Covers in which one or more lids or grids are inserted in a frame are known in various designs. Such covers serve to cover floor openings of any kind, for example to cover shafts and openings in floors and floors of buildings such as warehouses, workshop halls and other buildings, so that they can be walked on or driven over and can also be opened easily.
  • the frame is composed of several frame parts. These frame parts are butted together and screwed together at the intended joints, so that they then form a closed frame. The frame is then installed flush with the floor.
  • the frame parts have a frame wall, the upper edge of which is flush with the floor, and a frame foot, the latter as a support for one Cover or a grate is formed with which the bottom opening to be covered can be covered.
  • a disadvantage of the known embodiments is that the effort for the production of such covers is relatively high, since the joints of the frame parts and the covers and grids have to be machined at least partially. This is due to the tolerances of the frame parts, lids and gratings which are produced practically exclusively in a casting process. These tolerances do not allow proper assembly, especially when screwing the frame parts together.
  • this object is achieved in that connecting tabs projecting beyond the end of the frame wall with at least one bore for receiving the screw connection are arranged at the ends of the frame parts, of which connecting tabs opposite a first connecting tab at one end of the frame wall a second connecting tab at the other end is arranged lower on the frame wall, such that the connecting tabs are spaced apart in the frame in the case of two adjacent frame parts lie one above the other and are connected by the screw connection.
  • This arrangement of the connecting tabs allows the frame parts to be adapted to the cover or grate used in each case.
  • first connecting tab is arranged at a distance above the lower edge of the frame wall, since this provides space for the nut of the screw connection and does not protrude over the sole of the frame foot.
  • second connecting tab is arranged at a distance below the upper edge of the frame wall, so that the screw head of the screw connection does not protrude above the upper edge of the frame wall.
  • the invention also relates to a method for producing the frame for forming cover openings at bottom openings, the task of which enables the optimal production of the frame according to the invention.
  • This object is achieved according to the invention in that the frame is put together by placing frame parts on the lids or grids used and held together by screw connections, the frame parts being positively connected to one another by filling the cavities in the area of the screw connections and the connecting tabs with a filler material .
  • a frame 1 which is composed of two pairs of frame parts 2 which are connected to one another at their ends by transverse frame parts 3.
  • connecting tabs 4, 5 are provided which are arranged on the outside of the frame and lie one above the other.
  • the connecting tabs 4, 5 have a bore 6 or two bores 6, as shown on the left side of FIG. 1.
  • the number of holes is arbitrary.
  • Each frame part 2 has a lower-lying connecting tab 4 at one end and a higher-lying connecting tab 5 at its other end.
  • the transverse frame part 3 could also be provided at its ends with a lower and a higher-lying connecting tab 4, 5.
  • the one transverse frame part is provided at both ends with higher-lying connecting tabs 5 and the other transverse frame part 3 with lower-lying connecting tabs.
  • the frame parts 2 have a frame foot 7 which extends from the inside of the frame part 2 to the outside thereof.
  • a frame wall 8 on the frame parts 2 and the transverse frame parts 3 delimits the interior 10 of the frame 1.
  • two lids or grids can also be provided, which have the same dimensions as the frame part 2. Lids or roses of other sizes can also be used. Of course, it is possible to design frames with more than two pairs of frame parts; any number of frame parts and so many covers can be used on each side or grates as required to cover the opening formed by the frame parts 2, 3.
  • the connecting tabs 4, 5 lie one above the other, the lower-lying connecting tab 4 being arranged at a distance above the sole 11 of the frame foot 7 and the higher-lying connecting tab 5 below the upper edge 12 of the frame wall 8.
  • the two connecting tabs 4, 5 are connected by a screw connection 13, which is composed of a screw bolt 14, a nut 15 and a washer 16.
  • the bores 6 in the two connecting tabs 4, 5 are conical.
  • the higher-lying connecting tab 5 has a cavity 20 arranged on the underside, while two flat webs 21 are arranged on the upper side of the lower-lying connecting tab 4.
  • FIGS. 2 and 3 show a section through the bores 6 of the connecting tabs 4, 5.
  • the same reference numerals in FIGS. 2 and 3 denote the same parts. 3 corresponds to the fully assembled frame.
  • a positive connection is achieved by introducing a filling material 22 into the cavity 20 and into the bore 6 of the higher-lying connecting tab 5.
  • Molten aluminum, lead or a synthetic material in the liquid, paste or granulated state can be filled in as filler 22. This is done by turning the frame parts upside down, as will be explained in detail.
  • the assembly of the frame according to Fig. 3 proceeds as follows: The cover or grate or the gauge and the frame parts 2, 3 are placed upside down on an assembly base and the frame parts 2 are screwed together at their connecting tabs 4, 5.
  • the filling material 22 is filled into the cavity 20 and into the bore 6 of the higher-lying connecting tab 5.
  • the frame can be loosened by loosening the nut 15 its individual parts can be disassembled if this is necessary for transport purposes, for example.
  • the frame can be reassembled in the same way as when filling material 22 is filled in.
  • the conical design of bore 6 improves the connection of screw bolts 14 to frame parts 2 and facilitates removal of the screw bolt, if this should be necessary for any reason .
  • the assembly of the frame according to FIG. 4 proceeds as follows: It is not necessary to turn the parts upside down for this assembly.
  • the frame is made by setting up the frame parts 2, 3, by inserting the cover or the grids or the gauge and by screwing the frame parts to the screw connections 13 educated. Now the filling material 22 is filled into the cavity 23 of the lower connecting tab 4, which also flows into the conical bores 6 of the lower connecting tab 4, which are closed by a washer 24. If, after the filling material 22 has solidified, dismantling of the frame is no longer necessary, the screw connections 13 can also be mounted the other way round, ie with the nut 15 underneath.
  • the frame 1 described has the essential advantage that the parts of the frame and the cover or grids can be assembled without machining. Nevertheless, a clean storage of the cover and grate is achieved and the play of the same in the interior 10 of the frame can be adapted to the size of the cover or grate. By filling a filling material 22, the frame gets its stability.
