Abstract
TITLE OF THE INVENTION:
INSULATED HOLLOW CHAMBERED WALL PLATE STIFFENED
BY STRENGTHENING RIBS
ABSTRACT OF THE DISCLOSURE:
A hollow chambered wall of hollow sectional aluminum sections, strengthened by reinforcing ribs forms an insulated wall plate.
The ribs are secured to the chambered wall by screws screwed into blind riveted nuts. An insulating layer, for example a polyurethane foam layer, is applied to at least one outer sun-face of the hollow chambered wall. The reinforcing or strength-eying ribs, which rest on insulating shims or strips may be embedded in the insulating layer, or the layer may be applied between the ribs after the ribs have been attached to the chambered wall with the shims or strips.
INSULATED HOLLOW CHAMBERED WALL PLATE STIFFENED
BY STRENGTHENING RIBS
ABSTRACT OF THE DISCLOSURE:
A hollow chambered wall of hollow sectional aluminum sections, strengthened by reinforcing ribs forms an insulated wall plate.
The ribs are secured to the chambered wall by screws screwed into blind riveted nuts. An insulating layer, for example a polyurethane foam layer, is applied to at least one outer sun-face of the hollow chambered wall. The reinforcing or strength-eying ribs, which rest on insulating shims or strips may be embedded in the insulating layer, or the layer may be applied between the ribs after the ribs have been attached to the chambered wall with the shims or strips.
Description
it 1 FIELD OF THE INVENTION:
The invention relates to an insulated hollow chambered wall plate, which is stiffened by strengthening ribs screwed into blind riveted nuts. Such hollow chambered walls, preferably assembled from extruded aluminum sections which are welded together, should be well insulated when they are used for large cabins or chassis assemblies for vehicles in which people spend time or work. Such chambered walls are used, for example for constructing the wall plates of railroad cars.
DESCRIPTION OF THE PRIOR ART:
In known wall plates made of hollow chambered sectional sections, the insulation is arranged inside the hollow chambers. However, even with the insulation inside the chambers, such walls exhibit a high heat transfer rate due to thermal bridges extending from one side of the wall components to the other. Thermal flux occurs through the struts or partition walls of the hollow champ beredsections, which act as thermal bridges to conduct heat energy through the wall bypassing the insulation.
OBJECTS Of THE INVENTION:
In view of the foregoing it is the aim of the invention to achieve the following objects singly or in combination:
to provide insulated hollow chambered walls having a low thermal conductivity by eliminating as much as possible heat-bridging effects; and ,.
, Jo , ` ,:
I
1 to construct such hollow chambered walls to have a low thermal conductivity even when they comprise externally attached strengthening ribs.
SUMMARY OF THE INVENTION:
The above objects have been achieved in an insulated hollow chambered wall according to the invention by an insulation layer applied to at least one outer surface of the hollow chambered wall.-Strengthening ribs may be embedded or set into the insulating layer and rest on insulating strips applied between the hollow chamfered wall component and the strengthening member.
The essential advantage of the invention is seen in the achieve-mint of the smallest possible thermal conductivity coefficient for the hollow chambered wall, due to the placement of the insulation. An embodiment of the insulation for a hollow champ bored wall made of 35mm thick aluminum hollow chambered sections, with a 3mln layer of-foaming contact adhesive, a 20mm thick synthetic insulating foam layer, and a 2.5mm thick sheet of pressed particle board on the inwardly facing surface of the wall resulted in a low thermal conductivity coefficient of k = 1.1. The insulating according to the invention of the standard sections has many uses and is simple to carry out.
BRIEF DESCRIPTION OF THE DRAWINGS:
In order that the invention may be clearly understood, it will now be described, by way of example, with reference to the accompanying drawing wherein the single figure is a cross-sec-lion of an example embodiment of a hollow chambered wall with insulation applied according to the invention.
~L2~æ~2 THE BEST MODE OF THE INVENTION:
As shown by the embodiment of the single Figure insulation is applied to a hollow chambered wall 1 comprising extruded aluminum hollow chambered sections 1' with chambers 1". A
plurality of such sections may be welded together to form a wall plate 1. As preparation for applying the actual insulation, an adhesive base 2 and then an adhesive 3, for instance a foaming polyurethane adhesive, are applied on one surface of the hollow chambered wall. An insulating layer 4, for instance a puller-inane foam layer is applied to the adhesive 3. To increase strength and to protect the insulating layer 4, a sheet of pressed particle board 5 is applied as a cover, for example also by an adhesive. Other materials may then be applied as desired over the pressed particle board 5. For example, a floor underpayment or planking, or a finish coating may then be applied.
For securing a strengthening rib 6 to the hollow chambered wall 1 the above described insulation may be cut out in the width and length ox the strengthening rib 6. Alternatively, such a strength-eying rib 6 may be attached first, and then insulation may reapplied between the ribs 6. Before attaching the strengthening rib 6 blind riveted nuts 7 are inserted and secured in bored holes in the hollow chambered wall 1. Then rigid insulating strips 8, for example polyamide strips, are applied in the areas where the ribs 6 are to be attached. Then an insulating coating 9 such as a paint or adhesive coating is applied to the strips 8 and the strengthening ribs 6 are secured by screws 10 engaging the riveted nuts 7. To achieve an improved insulating effect, and to prevent the screws 10 and the collars pa of the riveted Lo 1 nuts 7 from acting as thermal conducting bridges, the screws 10 and the collars pa may be provided with a synthetic or plastic insulating jacket 11. Instead of the C-section ribs 6 shown, other reinforcing ribs such as U-section or L-section members may also be used for strengthening.
Although the invention has been described with reference to specific example embodiments, it will be appreciated, that it is intended to cover all modifications and equivalents within the scope of the appended claims.

Then an insulating coating 9 such as a paint or adhesive coating is applied to the strips 8 and the strengthening ribs 6 are secured by screws 10 engaging the riveted nuts 7. To achieve an improved insulating effect, and to prevent the screws 10 and the collars pa of the riveted Lo 1 nuts 7 from acting as thermal conducting bridges, the screws 10 and the collars pa may be provided with a synthetic or plastic insulating jacket 11. Instead of the C-section ribs 6 shown, other reinforcing ribs such as U-section or L-section members may also be used for strengthening.
