Abstract
A thermally broken spacer purlin has two or three galvanised steel sections which are interlocked together by means of further sections manufactured from a material which will not conduct heat. The dimensions of the steel sections 1 and 3 are variable to suit the specific application. Alignment of the steel sections 1 and 3 and the thermal break/s 2 can be misaligned to facilitate interlocking of sections together. <IMAGE>
Description
PATENT SPECIFICATION - THERMALLY BROKEN PURLINS.
This invention relates to a purlin for use in roofing structures, but which is thermally broken to prevent heat transmission.
The metal cladding and roofing of buildings in flat, corrugated or profiled metal sheets is a common practise. In many instances, to increase the thermal insulation values of the wall and or roof of the building concerned, two skins of metal cladding are often used, having a layer of insulation material such as glass fibre felt or polyurethane board trapped between. When two skins of cladding are used, the inner skin can be attached directly to the supporting structure of the building, but the outer skin has to be attached structurally to the building via a type of spacer which will bridge the thickness of the insulation. In many instances this problem is overcome by the use of a steel zed section known as a "spacer purlin" which is fixed through the inner sheet to the building structure and to which the outer sheet is then attached.Whilst this method is structurely sound, it does lead to the problem of heat transmission from the inside of the building through the spacer purlin to the outside, leading to heat loss and the distinct possibility of condensation lines on the liner sheet at the purlin positions. This problem is known as cold bridging.
According to the present invention the spacer purlin is manufactured from galvanised steel in a similar fashion to those commonly used, but is provided with one or two central section/s manufactured from U.P.V.C. which effectively break the continuity of the steel section and stops thermal transmission. The purlin can be manufactured in a variety of depths to suit different thicknesses of insulation. The alignment of the U.P.V.C. and the steel sections at the end of a length of section can be staggered thus allowing interlocking of a number of lengths of section to provide continuity over a greater length.
The features embodied in the invention are described by way Or the accompaning drawings in which:
Figure 1:- shows a sectional drawing through the thermally broken purlin showing the U.P.V.C. thermal break and the steel sections interlocked therein.
Figure 2:- shows the method of interlocking the ends of adjoining lengths of section.
Figure 3:- shows the configuration for deeper purlins using three steel sections and two U.P.V.C. ones.
Claims (4)
1. The spacer purlin prevents heat transmission from one flange to
the other by means of a U.P.V.C. interlock in the central web.
2. Lengths of spacer purlin can be interlocked together by means of
staggering the steel and plastic sections.
3. The spacer purlin is adequately strong so as to be able to stand
similar compression uplift and sheer loads to a continuous steel
spacer purlin.
4. The spacer purlin can be manufactured in the form of a single zed
section as sketch 1 or as a top hat section as sketch 3 for
applications needing increased strength.
