Abstract

SELF-SUPPORTING SHEET BINS INTENDED FOR THE ROOF COVERING, HAVING A PROFILE 1 ACCUSING GORGES 3 IN A WAY TO CREATE NARROW RIGOLES IN WHICH CAN BE ENGAGED, PROVIDED WITH THE FIXING OF INSULATING PANELS 5, DRAWNS WHICH SHOULD LEAF THE SIDES OF THE RIGOLE WITHOUT PERFORATING IT.

Description

The present invention relates to self-supporting containers

  for roofs with grooves intended to receive tapping lag bolts.

  These self-supporting trays are profiled sheets used

  selling blankets to buildings. It is often asked to fix on these tanks by means of screws or rivets, rigid or insulating panels, on which

  waterproofing works are sometimes also carried out.

The adoption of mechanical fasteners for mounting material

insulating material, rather than applying a hot bitumen coating, has been found

  lé essential because under the effect of depression or of air calls, the insulating material tends to detach or disintegrate, to the detriment of

  the waterproofing of the cover.

  Mechanical fixing, even if it allows satisfactory anchoring of insulating elements to the supporting sheet, however, requires drilling holes therein for the passage of the connecting members without being able to ensure perfect sealing at this location, and furthermore these openings expose the metal, which for example makes galvanized steel tanks subject to oxidation in the parts thus started. Furthermore, the time for producing such assemblies is considerably longer and requires special tools. Besides, the assembly screws or rivets, being visible from the inside, are of an aspect

  aesthetically unpleasant.

The same drawbacks as above persist when for the production of covers it is also provided outside, at

instead of a waterproof coating, a second tUlée layer placed on the ma-

  insulating material, "sandwich" according to the usual expression.

  The above-mentioned drawbacks are eliminated by making use of self-supporting roofing trays according to the present invention. 'it is necessary to drill holes in the sheet. This

  profiled sheet, reinforced by ribs, is rendered self-supporting.

Parallel to these ribs are provided by pleats turned back grooves of appropriate depth and section substantially recalling the shape of a gou

lying down.

These grooves with their vertical walls form channels serving as seats for lag bolts, the thread of the rod of which is engraved by tapping. Thanks to this solution, the insulating panel can be

  securely anchored to the tank without the need to drill it.

  The accompanying drawing shows, by way of nonlimiting examples, two embodiments of mounting insulating plates on -2 - -2- a493 98 & containers in accordance with the present invention. Figure 1 shows in cross section a portion of such a tray;

  Figure 2 shows how a pan is attached

insulating neau on a tank; Figure 3 shows in horizontal section one of the grooves formed in the sheet, constituting the tank after having engaged a lag screw

  Figures 4 and 5 are respectively a cross-section

side and a longitudinal section of an assembly of two superimposed trays between

an insulating panel.

The profiled sheet constituting a tank I according to the present invention comprises narrow grooves 3 of suitable depth, extending

  parallel to the reinforcing ribs.

  These grooves 3 have almost vertical walls, the spacing of which is advantageously smaller than the diameter of the threaded rod of a lag screw 4. Thus when this lag screw is introduced into one of the grooves 3 at any point thereof, and screwed electrically or by another suitable tool, its threaded rod is engraved there and the walls of the groove

tap accordingly to form a solid restraint.

Thanks to this arrangement, it is possible to fix an insulating panel 5, by means of lag bolts and small cover plates.

6 cleats.

  In addition, it is possible to plan by superimposing

  tion two tanks 1 and 7 (Fig. 4 and 5) containing an insulating panel 5 without the need

  to drill the bottom sheet 1.

  Here the lag screw will preferably be located at the top

of a reinforcing rib of the sheet 7 with storage of an overlapping saddle

Claims (4)

CLAIMS.   1. Self-supporting sheet metal trays intended for roofing, characterized in that their profile 1 shows grooves 3 so to create narrow channels in which can engage, provided with the fi-   xation of insulating panels 5, lag bolts whose threaded rod taps the sides of the channel without perforating it. 2. Self-supporting containers according to claim 1, characterized in that the grooves 3 extend parallel to the reinforcing ribs 2 in the profile of the sheet 1, their width being less than the diameter of the threaded rod of the lag screw.   3. Freestanding containers according to claims 1 and 2   characterized in that the grooves 3 in the profile of the sheet 1 are obtained by kink pleat.   4. Self-supporting trays according to any one of the preceding claims, characterized in that the installation of the tarau lag bolts   Deurs takes place by electrical or other screwing.
