Definitions

  • the present invention relates to a protective screen wall according to the preamble of Claim 1.
  • Such a wall is known from European Patent Application 0,104,867.
  • the adjoining panels near the adjoining edges are provided with an L-shaped outward projecting flange through which a bolt connection can be fitted.
  • L-shaped inward projecting accomodations are present on either side, for fitting a layer of lead placed between fibre boards.
  • the object of the present invention is to avoid the disadvantages described above and to provide an improved protective screen wall.
  • the connecting means now extend in the panel in housings fitted for them between the outside wall and the lead sheet. In other words, when they are fitted, an outward projecting part is no longer present, so that a flush finished unit is obtained, while the lead sheet is not drilled.
  • the housing for the radiation-inhibiting material is also used for accommodating a section, preferably a T-section, which forms an externally exposed edge between two protective screen panels. This produces a finishing moulding, and it is also possible to provide the body of this T-section with a recess for the overlapping edge part material.
  • the edge part material will in fact normally contain a lead material, which is relatively soft and difficult to handle.
  • the handling can be facilitated considerably by producing the T-section described above from, for example, aluminium, and by accommodating the lead material therein in the recess bounded therein.
  • the protective screen section used can be connected either to a further panel corresponding to the first panel mentioned or to a different type of panel, such as a pane.
  • the direct and simple connection to a pane makes a particularly simple modular construction of the device according to the invention possible.
  • the connecting means between the two wall parts can comprise any constructions known in the prior art. According to a preferred embodiment, a so-called "Sp ⁇ r" is used.
  • a bore is made near the edge in one of the external wall parts in both protective screen panels, said bores extending in the plane of the wall in line with each other when the panels are placed against each other.
  • a pin provided with conical recesses and tapered ends is placed therein.
  • a spör nut with hexagonal socket-head screw is then placed in the external wall parts concerned, at right angles to the plane of the panel, in the bores provided for the purpose.
  • a locking mechanism is provided by making these hexagonal socket-head screws engage with the conical recesses in the abovementioned pin.
  • the abovementioned external wall parts can comprise any materials known in the prior art, such as laminates.
  • At least one of those external wall parts is made of MDF (medium density fibre board) sheet material.
  • This sheet material is preferably provided with a finishing layer, such as veneer or HPL, the latter being a high-pressure laminate made of plastic.
  • the protective screen wall according to the invention is indicated in its entirety by 1 in Fig. 1. It consists of various types of protective screen panels 2 - 5.
  • Each protective screen panel 2 - 5 consists of two external wall parts 7, 8 and a sheet or membrane of lead placed between them.
  • the external wall parts 7, 8 are provided with a finishing layer 16 on the outside.
  • the external wall parts 7, 8 can consist of MDF material having a thickness of, for example, 18 mm and a height which depends on the application. A standard length of approximately 2.20 metres is envisaged here.
  • the sheet lead used can be, for example, sheet lead of the NHL 25 type which is 2.09 mm thick.
  • the finishing layer on the external wall parts can comprise 0.9 mm thick laminate material.
  • adjoining protective screen panels are provided with accommodation grooves 10.
  • a T-section 12 can be placed therein.
  • Said T-section 12 is provided with a recess 17, in which an edge strip of lead 11 is accommodated.
  • the T-section is preferably of anodized aluminium. It can be seen from the figures that the base of the T also forms a finishing moulding between two adjoining panels. The presence of the edge strip of lead 11 means that radiation is prevented from passing through the gap between sheets of lead of two adjoining wall panels.
  • the patient will generally be at the external wall part 7 side of protective screen panel 4, while the operative will be at the external wall part 8 side.
  • a so-called "Sp ⁇ r” system is present. This is shown more clearly in Fig. 3. It can be seen from this that a pin 13, which near the ends thereof is provided with conical recesses 15, extends in aligned bores of two adjoining protective screen panels.
  • the protective screen panels are provided with bores extending at right angles thereto, for the accommodation of spör nuts 14 with hexagonal socket-head screws 20. Tension is provided by tightening the hexagonal socket-head screws 20.
  • the distances here are selected in such a way that when the pins are pulled inwards fully, the panels will lie rigidly against each other, i.e. when the pins move inwards, the panels are pulled towards each other.
  • Such a construction is extremely strong and is not unattractive in appearance.
  • a slightly different construction is used in 4. It consists of a simple housing 22, in which an edge strip of lead 23 has been placed, which strip is not supported by a T-section or the like.
  • FIG. 2 A cross-section in the vertical direction at the position of a pane 18 is shown in Fig. 2.
  • This pane 18 consists of a lead glass material and has a thickness which lies, for example, between 7 and 8.5 mm.
  • the lead equivalent present therein is selected depending on the specified radiation, and in this case the values proposed by the National Radiological Protection Board (NRPB) are followed.
  • NRPB National Radiological Protection Board
  • Fig. 2 also shows how the underside of the panel according to the invention connects to the ground.
  • an H-section 19 with an overlap construction is present, and this can be seen in Fig. 4.
