Description

The invention relates to a section rail which is configured for connection to a wall and to a surface element. The section rail comprises a first section portion which is configured for fastening to the wall, which has a substantially L-shaped crosssection and which has a first limb and a second limb. The section rail furthermore comprises a second section portion which is configured for a reception of the surface element, which has a substantially U-shaped cross-section and which has a third limb and a fourth limb, with the limbs in particular being connected by means of a connection portion.

Such section rails are, for example, known from US2007/0107348A and are, for example, used to fasten surface elements such as studded membranes or studded films, sealing films, connection plates and the like to a wall and to simultaneously implement protection e.g. against the penetration of water into the region between the wall and the surface element. The section rails can contact plaster for this purpose and/or can also be plastered, wherein the first limb is in particular covered by plaster.

It can be difficult in such section rails to introduce the surface element uniformly into the second section portion over the total length of the section rail. In addition, the manufacture of the very complex shape of the section rail can be complicated and thus expensive.

It is the underlying object of the invention to provide a section rail of the initially named kind which allows a simple assembly of the surface element and which can be manufactured at low costs at the same time.

This object is satisfied by a section rail in accordance with claim 1 in that the first section portion and the second section portion are configured as separate parts which are connectable to one another.

Due to the aligned arrangement of the second and third limbs, these limbs can form a contact plane which, for example, areally contacts a wall. The surface element can now be displaced along the wall until it is correctly positioned within the second section portion. In this respect, it is of advantage that the wall can serve as a positioning aid, whereby the assembly of the surface element in the section rail is simplified.

The first limb and the connection portion can contact one another and/or merge into one another, whereby a transition between the first section portion and the second section portion is provided in the region of the first limb or of the connection portion. In particular in a section rail which is formed in two parts and in which the first section portion and the second section portion are formed from separate parts, the possibility can thus result of fastening the first section portion and the second section portion to one another in the region of the first limb or of the connection portion. The first section portion and the second section portion can hereby be manufactured separately from one another, whereby the manufacturing costs of the section rail can be significantly reduced. The section rail can consequently be produced more economically.

The section rail can, for example, also be attached to an external thermal insulation composite system (ETICS) and the like instead of to a wall. A fixing mortar can e.g. be used for an attachment, in particular a temporary attachment.

Preferred embodiments of the invention can be seen from the description, from the drawings and from the dependent claims.

In accordance with a first advantageous embodiment, the second section portion comprises a reception portion and the first section portion is plugged into the reception portion, with the connection portion in particular being arranged between the reception portion and the third limb or the fourth limb. In other words, the second section portion is formed such that a reception portion is formed. The first section portion can e.g. be plugged into or pushed into the reception portion, in particular in the longitudinal direction of the section rail. Alternatively, the connection between the section portions can also be established by a clipping in or a clicking in.

The production of the complete section rail from the first section portion and from the second section portion is thus possible in a simple manner by means of a pushing in or a clipping in or a clicking in, whereby the manufacturing costs of the section rail can be kept low. In addition, it is of advantage on the pushing in that a lengthening of the section rail is possible in that an offset is produced between the first section portion and the second section portion in the longitudinal direction of the section rail, whereby further first section portions and/or second section portions can be connected to the section rail.

On such a lengthening of the section rail, the fact can additionally be utilized that the butts of the first and second section portions (i.e. the points at which two first section portions or two second section portions impact one another) can be arranged offset from one another. An increased leak-tightness of the section rail against penetrating water or other liquids can hereby result.

The reception portion is preferably disposed opposite the third limb and/or the fourth limb with respect to the connection portion. This means that the reception portion is likewise arranged further above than the connection portion in a typical application in which the first section portion is arranged further above at a wall than the second section portion. The reception portion can then, for example, also be plastered and can be covered by plaster in this manner.

In accordance with an alternative embodiment, the reception portion can also be formed by the first section portion. In this case, a fastening portion of the second section portion is then plugged into the reception portion of the first section portion.

The connection portion preferably merges into the reception portion, wherein the reception portion extends away from the third limb beyond the fourth limb, then extends away from the fourth limb and subsequently approaches the second limb. The reception portion can therefore have at least two angled bends by which the reception portion can, for instance, comprise a parallelogram-like shape in crosssection.

Due to the angled bends, the reception portion can simultaneously serve as a drip edge. The reception portion can for this purpose extend further away from the contact plane defined by the second and third limbs than the first and fourth limbs. Generally speaking, the connection portion therefore merges into the reception portion and thus into the drip edge. The drip edge can be defined by one of the angled bends which has an angle of at most 90°, preferably of approximately 75°, and which thus forms a "sharp" drip edge. The drip edge can advantageously serve as a plaster removal edge at the same time, wherein the drip edge or the plaster removal edge can be approximately 15 mm away from the contact plane.

In accordance with a further advantageous embodiment, the first limb merges into a fastening portion which is adapted to the reception portion and which at least regionally contacts the reception portion. Generally speaking, the first section portion can therefore have a fastening portion which is adapted to the reception portion and which is pushed into, clipped into or clicked into the reception portion. The fastening portion is preferably arranged such that the first limb merges into the fastening portion.

The fastening portion can in particular likewise have two angled bends.

To further reinforce the fastening of the first section portion to the second section portion, the first section portion can comprise a reception pocket into which a projection of the second section portion projects. The second limb can, for example, comprise the reception pocket into which a rectangular bend of the third limb preferably projects. The bend of the third limb can also include an angle of smaller than 90°, e.g. an angle of 60°, with the contact plane, wherein the bend can in particular be rounded at a kink point. The reception pocket can contact the rectangular bend at two sides, whereby the connection of the first and second section portions can additionally be secured against relative movements of the section portions with respect to one another in a direction perpendicular to the insertion direction of the first section portion into the second section portion. The section rail can hereby additionally be stiffened, wherein a pushing or a clipping or a clicking of the section portions into one another remains possible.

The reception pocket can in particular define a hollow space which extends in cross-section substantially perpendicular to the direction of extent of the second limb. The size of the hollow space can be adapted to the size of the bent-over region defined by the rectangular bend.

In accordance with a further advantageous embodiment, an edge is attached to the reception portion, said edge extending in cross-section substantially in the direction of extent of the second limb and being configured as a plaster removal edge. The edge can therefore extend upwardly, i.e. can be oriented in the direction of a plaster of the wall, in the typical installation position of the section rail. The edge can in this respect be so far remote from the contact plane that a typical plaster thickness, for example 10 mm, is defined by the spacing between the edge and the contact plane. On plastering the section rail, the plaster can be removed at the edge or at the above-mentioned drip edge in a simple manner, whereby a selection can be made between two plaster thicknesses.

Alternatively or additionally, the first limb comprises a projection which extends in cross-section substantially in parallel with the direction of extent of the second limb and which is configured as a plaster removal edge. The projection can therefore satisfy the same function of the plaster removal edge as the above-described edge. Alternatively, the plaster removal edge can also be attached to the connection portion or project from the connection portion.

The third limb is preferably longer than the fourth limb. The third limb, which typically contacts the wall, in this manner allows the surface element to be introduced into the second section portion in a simpler manner. The handling of the section rail is thus facilitated.

The third limb and/or the fourth limb particularly preferably respectively has/have a folded edge which increases an opening angle between the third and fourth limbs. This means that the third limb and/or the fourth limb are bent away from one another in their respective end regions, i.e. extend away from one another, and increase an opening between the limbs in this manner.

In a region between the connection portion and the folded edges, the third and fourth limbs can be formed such that a spacing between the third and fourth limbs becomes smaller as the distance from the connection portion increases. Due to the decreasing spacing, the third and fourth limbs can develop a clamp or clamping effect and can thus secure the surface element, i.e. e.g. a studded membrane, against an unintentional sliding out from the second section portion. The third and fourth limbs can in particular be elastically bendable relative to one another for this purpose. The position of the folded edge can in this respect in each case be selected such that two stud rows of the studded membrane can be received and clamped between the third and fourth limbs.

In accordance with a further advantageous embodiment, the third limb has a desired breakage point. The desired breakage point is in particular arranged adjacent to or adjoining the connection portion. The third limb can be almost completely removed by means of the desired breakage point, for example by a cutting through by a knife or by a simple breaking off. After the removal of the third limb, the section rail approximately has a Z shape in cross-section which may be required for specific applications such as the bordering of bitumen sealing sheets or sealing films. The possible area of use of the section rail can be expanded in this manner. The desired breakage point can, for example, be a groove, a perforation or another material tapering in the third limb. Alternatively or additionally, the desired breakage point can also be formed from a material which differs from the remaining material of the second section portion, for example from a soft PVC. The desired breakage point can accordingly e.g. comprise an extrusion and in particular a groove composed of a soft PVC.

In accordance with a further advantageous embodiment, a surface defined by the second limb comprises cut-outs. The cut-outs can be provided in the form of circular holes through which plaster or mortar can pass on the plastering of the section rail in order to fasten the section rail to a wall. The surface defined by the second limb can additionally comprise a fabric and/or a mesh which can likewise be covered by plaster. The fabric can be connected to the second limb by means of welding, adhesive bonding, lamination or sewing. In addition, holes which are adapted to nails or screws can be present in the second limb, whereby the section rail can be temporarily or permanently fastened to a substrate by nails or screws. A surface defined by the fourth limb further preferably comprises cut-outs which are in particular arranged adjacent to the connection portion. The cut-outs can be formed as circular ventilation holes which are arranged along a straight line. The ventilation holes have the function of e.g. allowing moisture which increases at a studded film to exit from the second section portion. Damage by moisture or by a backlog of moisture can thus be prevented.

In accordance with a further advantageous embodiment, a projection which forms an abutment for the surface element is respectively attached to the third limb and/or to the fourth limb. The projections can respectively be arranged in an end region of the third limb and/or of the fourth limb which is adjacent to the connection portion. This means that the projection or the projections can suppress a pushing forward of the surface element up to the connection portion. In this manner, a ventilation passage is kept open by the projections and in particular makes it possible that moisture can move to the above-described ventilation openings in the fourth limb and can exit there.

The projections forming the abutments can be approximately square in crosssection and/or can each be oriented such that they are arranged between the third and fourth limbs. The abutments can facilitate the assembly of the surface element since they can predefine a defined end position of the surface element, whereby surface elements which are in particular rigid can be aligned relative to the section rail in a simple manner. The position of the abutments can additionally be selected such that two stud rows of a studded membrane can be received in the second section portion.

In accordance with a further advantageous embodiment, the connection portion extends away from the third limb beyond the fourth limb to form a drip edge. The drip edge can therefore also be formed independently of the reception portion. Alternatively or additionally, the drip edge can also comprise a projection which extends in parallel with the contact plane from the connection portion to the ventilation openings and which can thus protect the ventilation openings from driving rain.

The connection portion particularly preferably includes an obtuse angle with the second limb. The angle is in particular greater than 100°, preferably greater than or equal to 105°. This means that a slanted surface which enables good water drainage can be arranged in a transition region between the first section portion and the second section portion. The water drainage in this respect in particular takes place in the direction of the drip edge.

Alternatively, said angle can also be present between the first and second limbs.

In accordance with a further advantageous embodiment, the first section portion and the second section portion are formed from different materials. For example, the first section portion can be formed from a metal, in particular from sheet metal, copper, stainless steel, aluminum and the like. The manufacture from a metal increases the mechanical stiffness and stability of the section rail and additionally provides a valuable appearance. The second section portion can be formed from plastic, for example PVC (polyvinyl chloride). The formation from plastic enables a particularly simple manufacture of the second section portion and prevents corrosion of the second section portion.

Alternatively, the first section portion can also be designed from a plastic such as PVC and/or the second section portion can be designed from one of the mentioned metals or from a metal alloy. If the section rail is built up from two separate parts for the first section portion and for the second section portion, the different materials for the section portions can "work against one another", i.e. can move toward one another on different expansions due to changes in temperature.

In accordance with a further advantageous embodiment, the second limb comprises a double folded edge, in particular at its end region remote from the first limb. The double folded edge can provide a region of the second limb which extends in a pianoparallel manner with respect to the contact plane. The stiffness of the section rail can be increased due to the double folded edge.

The invention will be described in the following purely by way of example with reference to the drawings. There are shown:

Fig. 1 a section rail in accordance with the invention in a cross- sectional view:

Fig. 2 the section rail of Fig. 1 in a frontal view;

Fig. 3 the section rail of Fig. 1 in a perspective representation;

Fig. 4 a further section rail which is, however, not in accordance with the invention;

Fig. 5 the section rail of Fig. 4 in a frontal view; and

Fig. 6 the section rail of Fig. 4 in a perspective representation.

Fig. 1 shows a section rail 10 in a cross-sectional view which is configured for a reception of a surface element (not shown). The section rail 10 is configured for contact with a planar wall (likewise not shown) and comprises a first section portion 12 in an upper region (in the Figure) and a second section portion 14 in a lower region.

The first section portion 12 comprises a first limb 16 which is shorter than a second limb 18. The first limb 16 and the second limb 18 include an angle a of 105°.

The second section portion 14 has a third limb 20 which is arranged aligned with the second limb 18. The second and third limbs 18, 20 together define a contact plane (not shown). The third limb 20 is connected to a fourth limb 22 by means of a connection portion 24, wherein the third limb 20 extends further away from the connection portion 24 in its longitudinal extent than the fourth limb 22.

The connection portion 24 merges into a reception portion 26 at its end remote from the third limb 20, said reception portion 26 having a first bent-over region 28 and a second bent-over region 30. The first bent-over region 28 is defined by a bend of 75° which defines a drip edge 32. The first bent-over region 28 extends in parallel with the second and third limbs 18, 20.

The second bent-over region 30 extends in parallel with the connection portion 24 and with the first limb 16. Accordingly, an angle of 105° is present between the first bent-over region 28 and the second bent-over region 30. A plaster removal edge 34 extends from the second bent-over region 30 in parallel with the second and third limbs 18, 20 and away from the first limb 16. The plaster removal edge also extends from the first limb 16 to the second bent-over region 30, whereby a penetration of plaster into the region surrounded by the connection portion 24 can be prevented.

The third limb 20 and the fourth limb 22 respectively have an abutment 36 which defines a defined maximum insertion depth for a surface element pushed in between the third and fourth limbs 20, 22. A groove 38 which serves as a desired breakage point is provided in the third limb 20 at the side of the abutment 36 of the third limb 20 remote from the connection portion 24.

The third limb 20 and the fourth limb 22 extend away from the connection portion 24 and are configured such that they approach one another more and more as the spacing from the connection portion 24 increases until a folded edge 40, by which the third and fourth limbs 20, 22 are bent away from one another, is respectively provided at a position of the third limb 20 and of the fourth limb 22, whereby the spacing between the third limb 20 and the fourth limb 22 subsequently increases again. A respective projecting end region 41 of the third and fourth limbs 20, 22 is defined by the folded edges 40.

The third limb 20 extends at both sides of the connection portion 24, wherein an end of the third limb 20 remote from the folded edge 40 has a rectangular bend 42.

The second limb 18 extends in a straight line from a free end up to the rectangular bend 42 and in alignment with the third limb 20 and subsequently contacts the rectangular bend 42, whereby the second limb 18 forms a reception pocket 43.

In the Figures beneath the reception pocket 43, the second limb 18 contacts the third limb 20. The second limb 18 merges into the first limb 16 in the direction of the connection portion 24, wherein the first limb 16 contacts the connection portion 24 and the reception portion 26 and the region contacting the reception portion 26 defines a fastening portion 44. The fastening portion 44 accordingly, like the reception portion 26, has two angled bends having angles of 75° and 105°.

The first section portion 12 and the second section portion 14 are produced separately on the manufacture of the section rail 10. The first second portion 12 and the second section portion 14 are subsequently pushed into one another or clipped into one another or clicked into one another, wherein a stable fastening is made possible due to the fastening portion 44 engaging into the reception portion 26 and due to the second limb 18 running around the rectangular bend 42.

The section rail 10 of Fig. 1 is represented in a frontal view in Fig. 2. Two rows of circular plaster holes 46 which enable a plastering of the first section portion 12 are provided in the second limb 18. A row of ventilation holes 48 is introduced into the fourth limb 22, said ventilation holes 48 making it possible for moisture to exit which has been collected between the third limb 20 and the fourth limb 22.

Fig. 3 shows the section rail 10 of Figs. 1 and 2 in a perspective view. It can be recognized that the first section portion 12 is formed from a different material than the second section portion 14. The first section portion 12 is manufactured from aluminum and the second section portion 14 is manufactured from PVC.

On the use of the section rail 10, the second limb 18 is covered with plaster to fasten the section rail 10 to a wall. A surface element, e.g. a studded membrane, can subsequently be introduced so far between the third and fourth limbs 20, 22 until the studded film contacts the abutments 36. The studded film can be held in this position by means of clamping by the third and fourth limbs 20, 22.

Fig. 4 shows a further section rail 110 which is, however, not in accordance with the invention and which is formed in one piece. The section rail 110 in particular differs from the section rail 10 in accordance with Fig. 1 in that the first limb 16 and the connection portion 14 are identical or merge into one another. In addition, a drip edge 32 projects downwardly from the connection portion 24 and serves as an additional plaster removal edge. Furthermore, a plaster removal edge 34 which projects from the first limb 16 extends in parallel with the second limb 18. A double folded edge 50 is provided in the region of a free end of the second limb 18 and increases the stability of the section rail 110. The first limb 16 and the second limb 18 have approximately the same length.

The section rail 110 of Fig. 4 is represented in a frontal view in Fig. 5. Unlike the section rail 10 of Fig. 2, it can be recognized that the section rail 110 has only one row of plaster holes 46. This is due to the fact that the second limb 18 of the section rail 110 is connected to a fabric 52 (Fig. 6) to establish a permanent connection with the plaster.

Fig. 6 shows the section rail 110 in a perspective view, wherein it can be recognized that the fabric 52 is fastened to the second limb 18. The second limb 18 and the fabric 52 are covered by plaster to fasten the section rail 110 to a wall. Subsequently, a surface element which is held by the section rail 110 can - as described - be introduced between the third and fourth limbs 20, 22.
