  • This invention relates to a grating comprising a plurality of grating sections each formed from a plurality of spaced intersecting longitudinal strips and transverse strips, said longitudinal strips and/or transverse strips being provided with slots with which parts of said transverse and/or longitudinal strips are in engagement.
  • gratings may be used for numerous purposes, such as for ceilings, platforms and floors in boiler houses or machinery houses, etc.
  • the invention aims at providing a simple connection of the grating sections so that said sections are reliably interconnected and fit well together and the possibility is provided of removing any grating section independently of the other grating sections and putting it again in place. This is of special advantage if the grating is used as a ceiling or floor, because as a result of the removal of the grating section or sections in question any place above the ceiling or below the floor is accessible.
  • the grating according to the invention is characterized in that at least in the end portions of two grating strips of two adjacent grating sections facing each other and being substantially in alignment with each other a slot is provided, the slots in said'grating strips being provided such that with adjoining grating sections they meet, and in each of said slots there is provided at least one projection or depression, a connecting means for said grating strips being provided comprising at least one slot or recess into which the projections of slots provided in at least two grating strips facing each other grip, and a locking means being provided which prevents the connecting means from moving out of the slots.
  • the slots in the heads of the grating strips may preferably have an L-shape which is turned according to an angle of 90such that the long leg of the L is horizontal and the short leg points in downward direction.
  • the projection projecting in each of the slots is then located in the foremost slot portion.
  • the connecting means and the locking means may consist of a plate or strip and the height of the slot portions in the grating strips above the projections situated in said slots issubstantially equal to the thickness of the locking means.
  • the connecting means comprise two or more slots these are located at a distance fromeach other which is equal to the distance between the grating strips so that each slot may accommodate the heads of the opposite ends of two grating strips of adjacent grating parts. If the slots in the heads of the grating strips thereby have an L- shape which is turned according to an angle of 90 such that the long leg of the L is horizontal and the short leg points in downward direction, the projections grip into the slots of the connecting means.
  • the connecting plate or strip thereby preferably has a thickness which is equal to the height of the projections.
  • the locking plate or locking strip is slid which is of such thickness that it fills the slot space above the connecting plate or connecting strip and it preferably is clampingly held in said slot space.
  • the connecting means can be substantially U-shaped, the distance between the legs of the U being substantially equal to the thickness of the grating strips and the slot being provided in the body of the U.
  • the legs of the U thereby grip around part of the grating strips in question so that they are firmly held thereon.
  • At least one aperture may be provided in the connecting means and in the locking means; in said apertures a bolt, pin or similar locking means is provided.
  • the latter locking means may be embodied such that it can also serve as a suspension means for the grating sections in question.
  • FIG. I a top plan view of part of a grating consisting of two adjoining grating sections
  • FIGS. 2 and 3 on an enlarged scale a longitudinal section and a top plan view of part of said grating;
  • FIGS. 4 to 12 include connecting means and locking means in top plan view and in section respectively;
  • FIG. 13 a longitudinal section on an enlarged scale of said grating with plate members locked together by a bolt.
  • the grating sections 2 and 3 are arranged against each other such that their longitudinal strips 4 are substantially in alignment.
  • Each end portion of the longitudinal strips 4 comprises a slot 6 having the shape of an L turned according to such an angle that the long leg thereof is horizontal while the short leg points in upward direction. In this way a slot is formed with a projection 7 in each of the end portions of the longitudinal strips 4. Said slots are provided in the longitudinal strips such that they meet when said longitudinal strips are pressed against each other.
  • FIGS. 4 and 5 show a small connecting plate 8 which is slid into the slots 6.
  • Said small connecting plate 8 has such a length that it is greater than the distance between two adjacent longitudinal strips 4.
  • two transverse slots 9 the center lines of which are situated at a distance from each other which is substantially equal to the corresponding dimension of the grating meshes so that, when the small connecting plate is slid into the slots 6 of the longitudinal strips 4, said transverse slots assume a position under the projections 7.
  • the height of the projections 7 is substantially equal to the thickness of the small connecting plate.
  • the small connecting plate 8 has an aperture 11 and the locking plate an aperture 12, said apertures being provided in the plates such that, once said small plates have been inserted into the slots 6, said apertures face each other.
  • a bolt 20, pin, suspension hook or the like may be provided, as illustrated in FIGS. 3 and 12, so that both plates are locked relative to each other.
  • both small plates have a greater length than the distance between two adjacent longitudinal strips 4 and the mouth of the slot has a height which only equals the thickness of one plate, when the grating is assembled each of these small plates is put into the slots of adjacent pairs of longitudinal strips 4. After the grating parts have been pressed together the small locking plate is slid under or over the small connecting plate.
  • longitudinal strips 4 may also be provided such that the projections are pointing in upward direction. In that case the small connecting plate is moved downwards over said projections and the small locking plate is placed on the small connecting plate.
  • FIGS. 8 and 9 show a small connecting plate 13 comprising a ridge 14 and two slots 15 with a length which is substantially equal to the length of one projection. Said small connecting plate can only be slid in a direction transversal to the slots in question into the end portions of the longitudinal strips 4. The small locking plate thereby has half the width of the small connecting plate 8 and assumes a position at the other side of the small connecting plate than the ridge 14.
  • FIGS. 10 and 111 show a connecting means 16 which in cross-section is U-shaped.
  • a U-shaped connecting means serves to connect two opposite ends of two longitudinal strips.
  • the legs of the U are spaced apart over a distance which is substantially equal to the thickness of material of the longitudinal strips.
  • a slot 17 In the body of the U there is provided a slot 17 to accommodate the projections 7 of the end portions. Since the legs of the U render the connecting means very rigid, they may be only thin. The small locking plate may be only so thin that it can easily be mounted.
  • FIG. 12 shows a connecting means which at two opposite sides comprises a recess 19, the width between said recesses being substantially equal to the distance between two sides, facing each other, of two successive grating strips. Said recesses are provided in the longitudinal direction of the grating strips. Obviously instead of recesses also slots could be applied, as is shown in dotted lines 20 at one side of the connecting means shown in FIG. 12.
  • the grating consists both in the longitudinal and in the transverse direction of a plurality of components it is preferable to connect the transverse bars of the grating parts at various points in the manner described for the longitudinal rods. It is still to be noted that the invention is also particularly suitable for mounting grating parts behind which TL-tubes or other sources of light are provided.
