Description

The object of the invention are siding type profiles, intended for executing wall casings, in particular, on buildings, characterised by a structure enabling a stable connection of adjoining profiles and elimination of discontinuity between individual profiles. In the next aspect the object of the invention is a connection method of siding type profiles using the profiles according to the invention.
The siding type profiles are commonly used as wall claddings. In general the longitudinal connections of the profiles are realised by a lap system, however, the transversal connections are realised via a various kind of connectors. There are known various kinds of the connectors to connect two shorter edges of siding type cladding profiles. In general the connectors are elements made of the other material than the profiles. The connection executed via the connectors is clearly visible on the wall surface.
From the patent descriptions BE1016764 and WO2007/031527 it is known a front connection of two profiles characterised in that one end of the profile has a projection which is an extension of the external decorative layer and the other section is directed at an angle of α in the opposite direction to the external surface. The connection of two profiles is realised in this way that the external edge of the projection formed by the external decorative layer of the first profile rests on the external surface of the other profile. After the connection of two profiles a recess is formed at the place of the connection. The patent revealed several combinations of the projections of different shape but the basic idea is the same. One of the variants of the invention enables to form, at the place of the connection, a bulge instead of a recess. This type of the connection eliminates discontinuity between two profiles but their connection is only tangent and a separation of the profiles can occur under the influence of external forces.
Another method is connection method of siding type profiles consisting in removing a part of the external layer together with a part of a core of the profile on one end of the profile and on the other end the internal layer of the core of the profile is accordingly removed that at the place of the connection of two profiles they overlap forming a lap connection. In case of large temperature differences such a connection of the profiles results in gaps occuring in the decorative surface of the profile due to dimensional changes caused by contraction in case of cold. Such a connection does not ensure stability of the connection what is necessary for a proper utilization of the cladding in some cases.
Other method is a connection of two profiles wherein on one end there are a catch and a groove formed through removing a front part of the profile, and on the other end there are a reverse catch and a groove formed by removing an internal part of the profile. The catches are on the whole width of the profile and their connection on the lower and upper edge forms a system of five crevices what worsens aesthetics and increases water penetration. In order to connect two profiles an end of the other of connected profiles is put on the end of one profile from above, by vertical movement, whereas it is necessary to arrange a profile in air in parallel to a level of installed profiles because otherwise it is not possible to insert the catch of one profile into the groove of the other. With profiles of significant length this operation requires a participation of 2 persons.
The object of the invention is to develop a structure of profiles that could enable a simple, stable, tight and aesthetic connection of shorter sides of the profiles.
The object of the invention is a siding type profile containing a core, made of solid, foam or layered material, and an external face layer. The external face layer is made of hard material, especially PVC, and covers the whole face surface of the profile and a lower and upper edge of longer sides of the profile and fulfils a double function, namely casing and decorative function. The object of the invention is also a profile wherein a core of the profile has not a face layer or its role is fulfilled by paint or the other thin decorative element. In the further content of the description this type of the profile is treated on equal terms with the profile having a face layer. The profile has a rectangle-similar shape that, in the upper part on the whole length, has a recess whose bottom is an installation strip of known structures. Between this recess and the upper edge of the profile there is a catching flange. There is a longitudinal catch, in general, of L-shaped cross-section, on the internal side in the lower part of the profile on its whole length, and it is composed of the longitudinal catch and a base of the catch that connects the longitudinal catch with the core of the profile. The longitudinal catch is in relation to the lower edge of the profile at a distance making up a difference between a nominal width of the profile and the width of covering. This distance, keeping the afore-mentioned rule, is different for various dimensional variants of the profile. The longitudinal catch is used for lapping two adjoining profiles, whereas the connection is realised through inserting the catching flange of one profile into the longitudinal catch of the other profile.
The essence of the invention is to properly form the ends of the profiles, in particular extruded ones, adapted to connect the siding profiles on the shorter side.
In the first aspect the object of the invention is a profile having, on both ends, properly formed transversal catches consisting of a projection and a groove. The groove has the depth of no less than 5 % and no greater than 95% of the thickness of the profile, whereas, regardless of the thickness of the profile, the thickness of the profile at the place of the groove (A) is not less than 1 mm. Preferably, the groove has the depth of from 50 to 80% of the thickness of the profile, and most preferably, from 50 to 75%. The projection of the catch has the thickness (B) corresponding to from 90 to 5% of the thickness of the profile, whereas, regardless of the thickness of the profile, the thickness of the projection is not less than 2 mm, preferably, from 80% to 30%, and most preferably, from 80 to 50 % of the thickness of the profile. Furthermore, the thickness of the profile at the place of the groove (A) and the thickness of the projection (B) must fulfil the condition described by formula 1. $B - A = \geq 1 mm$
The transversal catches, on both ends, have a diverse but mutually compatible structure and after the installation they form a stable connection, whereas the thicknesses of the profile at the place of the groove (A₁, A₂) and the thicknesses of the projections (B₁, B₂) must fulfil the conditions described by formulas 2 and 3. $A_{1} + B_{2} = C$
$A_{2} + B_{1} = C$
where C is not less than 95% and not greater than 100% of the thickness of the profile.
Where A₁ and B₁ concern one end of the profile and A₂ and B₂ concern an opposite end of the profile.
On one end the transversal catch is directed in the direction of the face layer of the profile and has the width corresponding to the width of the profile between the installation strip and the internal edge of the base of the longitudinal catch. The installation strip and the catching flange are shorter on this end by a section corresponding to the width of the catch.
The face layer and the core on this end have also a relief limited, on one side, by an edge of the base of the longitudinal catch, and on the other side, by a line making up an extension of the edge of the transversal catch. The projection of the catch covers on this end only no more than a half of the length of the transversal catch, whereas it can be divided into several sections between which there are the gaps corresponding to the length sections of the catch. The length of individual sections of the projections of the transversal catch amounts to no more than 50% of the length of the transversal catch in case of a single projection of the transversal catch, and no less than 30% of the length of the transversal catch. The projection of the transversal catch, in the variant of the invention, is divided into the sections, whereas the length of the individual section of the projection is not less than 3mm. Preferably when the projection is divided into two sections at least while the sum of the lengths of the projections is not less than 40% and not greater than 50% of the width of the profile. On the other end the transversal catch is directed in the direction of the internal side of the profile and has the length corresponding to the width of the profile between the installation strip and the internal edge of the base of the longitudinal catch. The projection of the transversal catch on this end covers only no more than a half of the length of the transversal catch, whereas it can be divided into several sections between which there are the gaps corresponding to the length of the sections of the projection of the transversal catch. The installation strip and the longitudinal catch and the core between the seat of the transversal catch have the length corresponding to the face layer of the profile on this end, whereas in the core under the seat of the longitudinal catch there is a relief making up an extension of the groove and the projection of the transversal catch. This relief corresponds to the width of the section of the projection of the catch at least. The length of individual sections of the projections of the transversal catch amounts to no more than 50% of the length of the transversal catch in case of a single projection of the transversal catch, and no less than 30% of the length of the transversal catch. The projection of the transversal catch, in the variant of the invention, is divided into sections, whereas the length of an individual section of the projection is not less than 3mm.
The transversal catches on both ends are shaped compatibly in relation to each other that during the installation when both profiles are arranged in relation to each other with a shift in the vertical direction by the length of the individual section of the projection of the catch, the sections of the projection of one profile correspond to the gaps between the sections of the projection of the other profile, and after the installation the projections of one profile couple with the projections of the other profile.
On the end where the transversal catch is on the internal side of the profile the face layer, and in case when the profile has not a face layer - the external surface of profile, is shorter than the core of the profile by the width corresponding to the width of the catch. The transversal catch makes up from 0.6% to 30% of the length of the profile but no less than 6 mm and no more than 200 mm, whereas the width of the projection makes up no more than 50% of the width of the catch but no less than 3 mm. On the end whose projection is directed in the direction of the internal side of the profile, the projection has the width corresponding to the width of the groove on the opposite end, however, the projection on the opposite end can be narrower than the width of the compatible groove. It is preferable when both projections have the width corresponding to the width of the compatible grooves on the opposite ends in relation to them.
The reduction of the length of the installation strip and the catching flange can be done both on one and on the other end, whereas it is preferable when this reduction is done only on one end, preferably, on the end that has the transversal catch on the internal side of the profile. These reductions must be compatible in relation to each other, i.e. if these elements are reduced on one end they cannot be reduced on the other, or the reductions on both ends are in sum larger or at most equal to the width of the catches.
In the second aspect the object of the invention is a transversal connection method of the siding type profiles, consisting in connecting two profiles according to the invention via the catches that have a system of the projections which couple after the connection, forming a permanent connection. The connection by the method according to the invention consists in inserting the projections of one profile into the gaps between the projections of the other profile, and then moving this first one downwards what results in coupling the projections of both profiles, stabilising them simultaneously through inserting a catching tongue of one profile into a longitudinal catch of the other profile.
In the third aspect the object of the invention is a profile having the transversal catches shaped on both ends, whereas both ends have the inversely shaped but mutually compatible transversal catches. The transversal catches covers a basic part of the profile, however, the installation strip and the catching flange are shorter on one end by a section corresponding to the width of the transversal catch. Both transversal catches are shaped compatibly in relation to each other, whereas they consists of the projection located on the end of the profile and the groove located between the projection and a body of the profile. One end of the profile has a projection of the transversal catch directed in the direction of the front side of the profile while the bottom of the groove is located on the internal side of the profile. However, the projection of the transversal catch on the other end of the profile is directed in the direction of the internal side of the profile while the bottom of the groove is located on the front side of the profile.
The groove has the depth of no less than 5 % and no greater than 95% of the thickness of the profile, whereas, regardless of the thickness of the profile, the thickness of the profile at the place of the groove (A) is not less than 1 mm. Preferably, the groove has the depth of from 50 to 80% of the thickness of the profile, and most preferably, from 50 to 75%. The projection of the catch has the depth (B) corresponding to from 90 to 5% of the thickness of the profile, whereas, regardless of the thickness of the profile, the thickness of the projection is not less than 2 mm, preferably, from 80% to 30%, and most preferably, from 80 to 50 % of the thickness of the profile. Furthermore, the thickness of the profile at the place of the groove (A) and the thickness of the projection (B) must fulfil the condition described by formula 1. $B - A = \geq 1 mm$
The transversal catches, on both ends, have a diverse but mutually compatible structure and after the installation they form a stable connection, whereas the thicknesses of the profile at the place of the groove (A₁, A₂) and the thicknesses of the projections (B₁, B₂) must fulfil the conditions described by formulas 2 and 3. $A_{1} + B_{2} = C$
$A$ $_{2} + B_{1} = C$
where C is not less than 95% and not greater than 100% of the thickness of the profile.
Where A₁ and B₁ concern one end of the profile and A₂ and B₂ concern an opposite end of the profile.
The reduction of the length of the installation strip and the catching flange can be done both on one and on the other end, whereas it is preferable when this reduction is done only on one end, preferably, on the end that has the transversal catch on the internal side of the profile. These reductions must be compatible in relation to each other, i.e. if these elements are reduced on one end they cannot be reduced on the other, or the reductions on both ends are in sum larger or at most equal to the width of the catches.
On the end where the transversal catch is on the internal side of the profile the face layer is shorter than the core of the profile by the width corresponding to the width of the catch. The transversal catch makes up from 0.6% to 30% of the length of the profile but no less than 6 mm and no more than 200 mm, whereas the width of the projection makes up no more than 50% of the width of the catch but no less than 3 mm. On the end of the profile whose projection is directed in the direction of the internal side of the profile, the projection has the width corresponding to the width of the groove on the opposite end, however, the projection on the opposite end can be narrower than the width of the compatible groove. It is preferable when both projections have the width corresponding to the width of the compatible grooves on the opposite ends in relation to them.
The connection of two profiles is realised through putting one end onto the other and shifting the installed profile downwards and then the connection is locked as a result of sliding the catch over the catching tongue.
