Description

Various proposals have been made to seal the seams between interlocking building panels in such a way that an effective seal against liquid and daffodil results. However, these suggestions are not always
been economically acceptable for a variety of reasons
Establish. In some cases the particular sealing elements that have been used have the interlocking of the
Plates disturbed and a full and effective engagement
prevented each other. In other cases where the interlocking of the relevant parts of the plates has been taken into account during manufacture and has been found to be satisfactory, the sealing element has been adversely affected, so that the desired operation of the sealing

In other words, the prior building panels, and particularly those interlocking building panels and their training, were mostly caught because the interlocking parts of the panels do not always move with the seals that seal the seams between the Plates were used, tolerated and vice versa. Beispfele for earlier panels and connections are in US patents 3 320 706, 3 367 076 and 3 290 845 are shown.

of part 12 attached. A weather strip 16 is on a side edge of the insulating layer 14 preferably during the manufacture of the building board 10 attached by gluing. The entire opposite marginal edges 5 and 7 of the building board 10 (Pig. 3) have side walls or flanges 17, 18 on the sheet metal 12 and on the opposite one Longitudinal edge of the insulating layer 14. The strip 16 is substantial narrower compared to the thickness of layer 14, but is long enough to cover the entire length of the Plate 10 to run. This strip has certain advantageous properties in terms of its composition and structure, which will be described in detail below.

The panels at hand can be either indoor or Form external wall or Daoh components of a building, for example as in Pig. 1 for a roof, shown in a preferred embodiment of the invention. Building panels 10 of the present invention can, as shown in Fig. 6 shows, are abutted back to back and form a double-sided wall, which you z. B. can be used for freezer rooms that can be entered. If desired, For example, the outer surface of the insulating layer 14 can be glued to a thin, resistant coating 20. The coating 20 can be a layer of aluminum foil or any other material that is moisture-proof

Like from Pig. 5, the coating can also be in the form of a laminate consisting of Kraft ™ paper 21 of a suitable type, which is attached directly to the layer 14, a thin glass fabric and an outer layer of a very soft aluminum foil 25, which is shown in FIG Pig. 5 is shown. The entire laminate, which forms the coating 20, should be relatively thin, for example about 0.25 mm, the paper cover 21 having a thickness of the order of 0.2 mm .03 mm and the aluminum foil about 0.02 mm _o All is desired and depending on the particular composition of the insulating layer 14, an adhesive layer 15 can be applied to the back of the part 12 of the plate 10 in order to connect the insulating layer 14 with the part 12 to produce.

As can be seen from the drawings, if the part 12 is made of metal, for example aluminum or an aluminum alloy, is dented over by rolling, so that the sheet metal 14 "results and the two planes 17 and 18 _r the surface of the sheet 14 * further with a number of ■ reinforcement ribs 28 and reinforcement® strips 29 at the transition points between Bleofa 14 ⁸ and splash 17 and 18 be provided.

31 forms. The free marginal edge of the flange is also rolled, but in the opposite direction to that of the flange 17, so that a deformable, upwardly protruding tube-shaped sleeve extending in the same direction is formed

32 forms a slightly larger diameter.

As described in US Pat. No. 3,312,028 and in the present application, when two building panels are placed side by side and crosswise on a number of underlying, separately extending beams 34, in such a way that the flanges 17 and 18 of converging plates protrude above the top, which a tubular sleeve 32 of the flange 18 of the one plate 10 over the tubular edge 30 brought the flange 17 and then mediate a suitable tool, as it is, for.

Although the length of the single bracket compared to the length of the plate 10,

. is small., the bracket holds 36 pairs of abutting each other Plates 10 securely on the carrier 34.

The connection that results from two non-insulated metal parts 12, through the sleeve 32, which over clamping the tubular rim 30 with the clamp 36 therebetween will normally provide a sufficient one Watertightness and the problem of moisture ingress to which the present invention relates don't sieve. If, however, the metal parts 12 are provided with insulating or underlay layers 14 before they are installed

w tion, problems with moisture occur at these joints. In the most common use of composite building panels 10, the insulated side of the panel 10 will face the interior of a building or a room in a structure, while the raw, non-iso. lated side of the panel is on the outside of the wall or roof structure.

Under such conditions, and due to the usual differences in vapor pressure and temperature that occur between the cold and warm sides of the building panel 10, the passage of steam through the joints between the individual panels creates a problem. Due to the balancing tendency between these different pressures and temperatures on opposite hot and cold sides of the building board 10, each gap 50 between the marginal edges 5 and 7 of adjoining building boards tends to act as a conduit for moisture in vapor form to pass through. The steam stro:.] B generally approaches the colder area and finally condenses. The condensate then collects at the marginal edges 5 and 7 of the panels 10, which form the gap 50 if these gaps 50 are not effectively sealed against the passage of moisture or steam, and particularly migrates into the area of the warm side of the building panel 10.

The gaps 50 are usually left for manufacturing reasons, when built-in building panels are manufactured and due to manufacturing tolerances.

The term ^H perm ^B , as used in the present application, refers to the amount of atmospheric moisture in vapor form that penetrates through a porous material due to the pressure differences on opposite sides of the material as well as due to the hydrostatic pressure on opposite sides ₀ A "perm ^ unit, as used here, is equal to one grain of water per hour per square foot per 1 inch of mercury vapor pressure difference.

A Feuchtigkeitskonsentration in liquid or vapor form occurs primarily in ü®n Spaltea 50 of the ¥ Getting Connected sewed on the boards because SSER largest percentage of the entire structure of such building boards, including the plating 20 relatively unaffected by changing temperature and pressure gradient on opposite sides of the building boards 10 is. In addition, the gaps 50 are created by the fact that the planes 17 and 18 can be offset slightly outwards, based on the vertical plane of the side surfaces of the foam insulation, which is due to the normal manufacturing tolerances that occur during the manufacture of the building boards 10.

The aforementioned accumulation and passage of moisture in liquid and vapor form through the Gaps 50 are made effective for all practical purposes by the weather strip 16 attached to one side of the building panel

As can be seen from Figures 2 and 4, the weather strip fits 16 into the gap 50 and bridges this when Kwei building boards 10 are assembled so that an effective vapor barrier and illumination at this joint seam ercibt. The strip which extends over the full length of the building panel 10 originally has one Thickness which is greater sls the gap is wide and a height the smaller is the total depth of the gap 50, the to seal irt. Generally, the gap 50 is at the Connection points according to FIGS. 2 and 4 about 3 mm wide with a tolerance of - 1.5 mm. When initially attached to a layer 14, the strip 16 would have a width in of the order of 6 mm. The strip 16, when inserted into a gap 50, is compressed approximately 1/2, so that it has a width of. 3 πια has. The stripe 1c can consist of an impermeable sponge like sponge Material of suitable hardness exist so that it is easily compressible and yet sufficiently resilient to spring back and to completely seal the gap 50 without developing any strong force at the same time, forcing the panels apart, thereby weakening the connection between edge 30, sleeve 32 and bracket 36 or would be adversely affected in any other way.
