Description

PLASTIC SKIRTING RANGE FOR THE CONSTRUCTION SECTOR

According to a first aspect, the invention relates to an assortment of plastic angle strips for the construction sector, the angle strips of the assortment each having:

(a) a longitudinal projection on the outside at the angle apex;

(b) a mesh-like reinforcement material for the plaster on a building wall provided with thermal insulation, the reinforcement material being fastened to the angle strip and leading away at least on one of the two legs of the angle strip;

(c) and an elongated fastening element which is clamped onto the longitudinal projection with the interposition of a region of the reinforcing material,

and wherein the angle strip assortment contains several of the following types of angle strips (d) to (f):

(d) plaster corner strip with reinforcement material leading away from both legs;

(e) a pair of expansion joint end strips, in which reinforcement material leads away on one strip leg and a plastic film strip on the other two, adjacent

Thighs is attached;

(f) Plaster connection strip, in which reinforcement material leads on one leg: and an adhesive tape is provided on the other leg. The range of angle strips according to the invention has the very significant advantage in practice that a basic type of strip with the features (a), (b), (c) is either identical or with small changes in manufacture as a starting point for the angle strip types (d), (e) , (f) can be used. The different types of angle strips are normally produced in the manufacturer's plant.

In a preferred development of the invention, the angle strip assortment contains several of the following types of angle strips (d) to (h):

(e) a pair of expansion joint strips, each of which carries reinforcement material on one strip leg and a plastic film strip is attached to the other two adjacent legs;

(f) Plaster connection strip, in which reinforcement material leads away on one leg and an adhesive tape is provided on the other leg.

(g) Drip nose strip or joint cover strip, in which the fastening element has a supporting leg, which runs essentially parallel to one leg of the angle ledge, and in which either reinforcement material leads away on both legs or leads away from reinforcement material on one leg and on the other Leg an adhesive tape is provided;

(h) Plasterable corner plaster, in which the fastening element has a plaster anchoring structure with depressions on its front side and in which reinforcement material leads away from both legs.

Nowadays, building walls are increasingly being provided on the outside with thermal insulation made, for example, of rigid foam or fibreboard. In order to give the plaster that is applied to the thermal insulation good strength, a mesh-like reinforcement material is normally arranged on the thermal insulation.

It can be provided that the fastening element with its corresponding outer area also forms a corner edge for the plaster. This makes it easier to apply the plaster and creates a cleaning corner edge that is both optically perfect, especially with regard to the straight course, and prevents plaster damage, particularly in the vulnerable corner area.

A fine or coarse fiberglass fabric with square openings between the fiberglass strands is mostly used today as a plaster reinforcement material on thermal insulation, and this

Reinforcing material is also preferred for the angle strips according to the invention.

It has turned out to be particularly favorable both with regard to the manufacture and also with regard to the attachment of the fastening element if the longitudinal projection is essentially square in cross-section, with a transition on a square corner into the main part of the angle strip.

At least one of the legs of the angle bar preferably has

Breakthroughs. The angle bar can be attached particularly easily in this way, for example by first applying some filler to the thermal insulation and then the angle bar with the leg or legs in question presses into the filler; part of the filler swells through the opening - ¹ g »e * n.

The side surfaces of the fastening element, which serve the plaster connection, are preferably corrugated, roughened or otherwise designed to be uneven, so that the best possible bond to the plaster is achieved here.

In the case of the angle strip, the fastening element preferably protrudes at the first end by a first partial length and ends at the second

End set back by a second partial length. With this design, the next following angle bar can be coupled in the simplest way. For this purpose, the protruding, first partial length of the

Fastening element simply placed on a partial length of the longitudinal projection of the next angular strip, which is free of the fastening element. This is automatically accompanied by an aligned

Align the two adjacent angle bars.

The second part length is preferably equal to or longer than the first part length. In this way, the protruding first partial length can always be easily connected when connecting the next angular strip.

Preferably, the fastening element with interposed reinforcing material is in positive engagement with the longitudinal projection. In this respect, one could also speak of the fastening element being snapped on. In this way, a secure and fatigue-free attachment of the reinforcement material to the angle bar is created.

In a preferred embodiment of the invention, the longitudinal projection has no cavity open to the inside of the angle bar. With such a cavity there is a risk that it will not be completely filled with filler or plaster when the angle bar is attached, so that condensation water can occur there with negative consequences for the adhesion of the angle bar. The plaster connection strip is preferably intended for use on door frames or window frames. A foam adhesive tape is preferably used as the adhesive tape.

In the case of the expansion joint end strips, the leg to which the plastic film strip is attached, preferably glued, can be designed without openings, but optionally also with openings.

Another object of the invention is, according to a second aspect, an expansion joint termination as set out in claim 6.

Another object of the invention is, according to a third aspect, a drip nose strip or joint cover strip, as set out in claim 7.

Thermal insulation on building walls usually has a lower end slightly above the surface of the soil or a soil fixture that reaches the building wall.

The lower end of the thermal insulation is a critical area, because moisture can penetrate from below between the building wall and the thermal insulation and between the thermal insulation and the external plaster, which can result in damage and even crumbling plaster.

To improve the situation in the lower end area of the thermal insulation, metallic angle rails have been used so far, which were fastened to the structure with a first leg and the second leg, which was perpendicular to the thermally insulated

Building wall extended against the lower end face of the insulation. However, this known solution cannot be completely satisfactory because the lower end area of the thermal insulation still remains quite damp during precipitation; With Corrosion on the end rails must be expected over the long term.

In the drip nose bar according to the invention, the supporting leg of the fastening element projects downward and thus forms one

Drip nose for water. This keeps the metallic angle rail drier, since the drip nose strip is made of plastic, corrosion problems are eliminated here.

The joint cover strip according to the invention can be used in pairs with the supporting legs of the fastening element converging towards one another. In this case, a joint cover is created, which covers the joint behind it in building thermal insulation or building sound insulation (e.g. impact sound insulation with screed applied to it on floors), whereby the insulation joint is often a correspondence to the building joint underneath.

Preferably, the drip nose bar or the joint cover bar is provided as an outer bar on an angle rail made of metal or plastic, the first leg of which is provided for attachment to the structure and the second leg of which is intended to bear against an end face of the insulation, whereby a launch rail for building thermal insulation is created.

Another object of the invention is, according to a fourth aspect, an overputable plaster corner molding as set out in claim 8.

The plaster corner trim according to the invention realizes the concept of being able to serve as a pull-off edge when attaching a layer of plastic material to the thermal insulation, preferably a layer of filler, but on the other hand the angle bar can be completely embedded in the plaster layer applied afterwards and the plaster optimal Anchoring conditions offers. The angle bar on the finished building is no longer visible, which also satisfies high aesthetic demands. Nevertheless, the angle strip makes the plaster more resistant, particularly in the damage-sensitive corner area of a building wall, because it has a supporting function from the inside.

Preferably the front of the fastener, i.e. that part of the surface of the fastening element which is covered with the plaster layer is corrugated. This is the simplest, but functionally sufficient type of training for many applications

Providing longitudinal corrugations on the front. The longitudinal corrugations can easily be e.g. be produced during the extrusion of the angle bar or the relevant part of the angle bar. In terms of function, it is even safer to corrugate the front side with two intersecting corrugation directions, in particular along the angle bar and transversely thereto, or both corrugation directions obliquely to the longitudinal direction of the angle bar.

One becomes particularly free in the choice of the design of the plaster anchoring structure when the plaster anchoring structure is inserted into the material of the material using a tool, preferably a rotatable tool

Angle bar is pressed. This type of production is somewhat more complex than e.g. the extrusion through a ripple producing

Nozzle, but still reasonably efficient. In the case of plastic angle strips, the easiest way to press in the plaster anchoring structure is in the plastic, which is soft due to its temperature, this softening preferably being carried out, for example, with hot air in order to press in the plaster anchoring structure. The production of indentations with the help of rotatable tools is often called "knurling" and is considerably more widespread for metal parts, for example for operating knobs, than for plastic parts. The invention and embodiments of the invention are explained in more detail below with the aid of exemplary embodiments shown in the drawings. It shows:

Cross-section.

In Fig. 1, a house wall 2 is drawn with an outside corner 4. On the outside of the house wall 2, thermal insulation 10 is applied, e.g. consists of polystyrene plates. Corresponding to the wall corner 4, the thermal insulation 10 has an external thermal insulation corner 12.

On the thermal insulation corner 12, an angle bar 14 made of plastic or metal is placed on the outside of the thermal insulation 10 and fastened to the thermal insulation 10 in a manner to be described below.

The angle bar 14 extends along the thermal insulation corner 12 in the vertical direction. Except for one to be described later

Longitudinal projection 16, the angle bar has a right-angled angle profile with two legs 18. On the outside, the angle bar 14 has, as it were, a longitudinal projection 16 on the angle apex, which in the embodiment shown has a square cross section and merges into the main part of the angle bar 14 on a square corner. A section of a mesh-like reinforcing material 28, preferably made of glass silk fabric, is fastened to the angle bar 14. The reinforcement material 28 is fastened in that it has been placed over the longitudinal projection 16 and that an elongated fastening element 30 has then been snapped onto the longitudinal projection 16 with the reinforcement material 28 interposed. The fastening element 30 has an inner contour which is essentially matched to the outer contour of the longitudinal projection 16. In order to enable attachment to the longitudinal projection 16, the fastening element is

30 open as it were in the area of a square corner, that is, formed as a channel-like profile. It is understood that this open side is less wide than the cross-sectional diagonal of the longitudinal projection 16, so that the fastening element 30 by spreading during attachment and subsequent merging form-fitting on the longitudinal projection

16 is snapped on. In this way, the reinforcement material 28 is held in a clamping manner between the longitudinal projection 16 and the fastening element 30.

If a plaster layer 32 is to be applied to the thermal insulation 10, a filler layer 34 is first applied to the outside of the thermal insulation 10, also in the area of the corner 12. Then the angle strip with the section of the reinforcing material 28 attached to it is placed on the corner 12 pressed into the still smooth filler 34. Besides, that will

Reinforcing material 28 pressed into the still smooth filler 32. Then additional filler is applied thinly from the outside over the reinforcing material 28.

In Fig. 2 it can be seen that with an angle bar 14a

(bottom right in FIG. 2) the fastening element 30 at the drawn second end set back by a second partial length 36 before the second end of the angle bar 14 ends. In the case of the angle strip 14b to be attached next to the corner 12 (top left in FIG. 2), the fastening element 30 stands around a first at the drawn first end

Part length 38 over. The second part length 36 of the angle bar 14a is equal to or longer than the first partial length 38 of the other angle bar 14b. It is understood that the angle bar 14a is formed at its other, first end like the angle bar 14b at its first drawn end and that the angle bar 14b at its other, second end is designed like the angle bar 14a at its second drawn end The End.

When the angle bar 14b is attached to the corner 12, the overhang 38 of its fastening element 30 is snapped onto a partial length of the longitudinal projection 16 of the angle bar 14a, which results in a mutual anchoring and aligned alignment of the two angle bars 14a and 14b.

FIG. 2 also shows triangular perforations 40 in each of the legs 42 of the angle strips 14a and 14b.

The triangular openings change their orientation by 180 ° from opening to opening. When pressing the angle bar 14, part of the filler 34 penetrates the

40th

After the filler 34 has tightened or hardened, the plaster layer 32 is applied. It can be seen that the regions 44 of the fastening element 30 form extraction surfaces which enable the plaster 32 to be smoothly driven to the required thickness. The areas 44 together with the transition rounding 46 form a corner boundary edge for the plaster 32. It should be mentioned that the areas 48 of the fastening element 30 to which the plaster 32 is connected are corrugated in the longitudinal direction of the angle bar 14, so that the plaster 32 there a good bond with the angle bar 14 is received.

It should also be mentioned that there are also plasters in which the spatula 34 described on the thermal insulation 10 is not required. In this case, only the angle bar 14 is fastened to the thermal insulation 10, for example by means of its adhesive mortar; the reinforcing material 28 is embedded directly in the plaster layer 32. In both cases, the reinforcement material 28 forms one Reinforcement for the plaster 32 and keeps it crack-free even with large temperature fluctuations.

It is understood that the angle bar 14 has a constant profile over its length, that is, both the legs

40 and the longitudinal projection 16 extend in the longitudinal direction of the angle bar.

The legs 40 are typically approximately 1 mm thick and approximately 10 to 50 mm wide in the horizontal direction of FIG. 1. The legs 40 are somewhat expandable elastically. The reinforcing material sections are typically 10 to 15 cm wide in the horizontal direction of FIG. 1; additional reinforcement material for the continued plaster layer 32 is connected in an overlapping manner.

In Fig. 3, an angle strip designed as a plaster connection strip is shown. In contrast to the angle strip according to FIGS. 1 and 2, the reinforcement fabric 28 covers only one of the two legs 40 and is guided away a little from there. On the outside of the other leg 40, a double-sided adhesive foam plastic adhesive tape c is glued on. The angle strip is attached to one by means of the adhesive tape 50

Window frame 52 glued.

In Fig. 4 the formation of the angle bar 14 is illustrated as an expansion joint termination. It is a pair of

Angle strips 14 available. Of the one pointing to the left in FIG. 4

Leg 40 of the left angle bar 14 and on the leg 40 of the right angle bar 14 pointing to the right in FIG. 4 is in each case one

Section of reinforcing material 28 provided and continued. On the other leg 40, i.e. A plastic film strip 52 is glued to the most closely adjacent legs, which run from bottom to top in FIG. 4. The plastic film strip 52, laid in a U-shape, covers an expansion joint 54 between two

House wall sections 2. You can see the thermal insulation 10 of the house wall sections. In this way the expansion joint is waterproof and durable edichtet from ^g. In the exemplary embodiments according to FIGS. 3 and 4, the reinforcing material 28 is attached to the respective angle bar 14 by means of the fastening element 30. For the longitudinal connection of two angle strips 14 with the aid of the fastening element 30, what has been described in particular in connection with FIG. 2 applies.

The invention and embodiments of the invention are explained in more detail below with reference to exemplary embodiments shown in the drawings. Show it:

Fig. 1 'a house wall with thermal insulation and lower

From the end of the rail insulation, in vertical section;

Fig. 2 ¹ a building wall at the transition into a building recess, with on the outer corner of the

Transition an angle bar is provided, in vertical section.

In Fig. 1 'can be seen on the left a hatched house wall 2, in the right thermal insulation 4 z. B. is applied from polystyrene plates.

At the lower end of the thermal insulation 4, an end rail 6 is provided. The end rail 6 consists of an angle rail 8 made of metal, the first leg 10, which projects upwards, on the wall

2 is attached, e.g. B. by shot bolts. The second leg 12 of the angle rail 8 protrudes horizontally outwards from the wall 2 and has a small S-bend downward at its outer end.

The second part of the end rail 6 is an outer strip 14 made of plastic, which is glued to the top of the second leg 12 of the angled rail 8 in the region set back by the S-offset with a foam adhesive tape or compressed sealing tape 16. The outer bar 14 has a substantially horizontally extending, first leg 18, which is glued to the angle rail 8, and a downwardly projecting, second leg 20. The second leg 20 does not extend exactly vertically, but has a slight oblique orientation towards Wall 2. The second leg 20 extends further down than the

Angle rail 12 is located with its recessed area. The first leg 18 of the outer bar 14 consists of two areas which are connected to one another via a film hinge 22. The upper area is folded through 180 ° and a glass silk fabric section 24 is clamped between the two areas. The flipped top

The area is hooked in a form-fitting manner behind a nose 26 of the outer bar 14.

When using the end rail 6 described, you normally work in such a way that first the angle rail 8 on the

Building wall 2 is fastened, usually several angle rails 8 one by one along the length of the wall 2, it being possible to work with overlaps at the transitions. Then the outer bar 14 is glued on, usually several one after the other along the length of the angle rails 8. Then the bottom ones

Polystyrene panels of the thermal insulation 4, as it were, placed on the end rails 6 and fastened to the wall 2 in a conventional manner. Now the glass silk fabric section 24 is fastened from the outside with filler to the outside of the thermal insulation 4. It goes without saying that further glass silk fabric, which is not shown, adjoins the section 24 in an overlapping manner and is also fastened to the thermal insulation 4. After the filler has tightened or hardened, a plaster layer 28 is applied on the outside. The outside of the second leg 20 of the outer bar 14 pointing to the right in FIG. 1 can be used as

Serve deduction edge. It is pointed out that the outer strip 14 is provided with longitudinal corrugations in the area where the plaster layer 28 is connected to it at the end in order to ensure a good bond to the plaster.

It can be seen that the second leg 20 of the outer strip 14 forms a drip nose for water extending along the lower end of the thermal insulation 4. The underside of the angle rail 8 remains optimally dry. If you also imagine the arrangement of end rail 6, thermal insulation 4 and plaster layer 28 rotated by 180 ° in mirror image from below, you can see that a joint cover is created with the two second legs 20 of the two outer strips 14 now facing one another. Here, the free ends of the second legs 20 can either have a small distance from one another or just touch or have a small overlap. Normally, the joint of this type between the end faces of two sections of the thermal insulation 4 corresponds to a building joint in the wall 2.

A horizontal joint is available for the mirrored addition described. If you turn the whole thing by 90 °, you have a vertical joint, which is the more common case in buildings.

It is easy to imagine that corresponding joint covers can be made in impact soundproofed floors. Here the second legs 20 of the outer strips 14 no longer have a drip nose function, but only a joint covering function.

2 again shows a building wall 2 with thermal insulation 4, but it is a recess of the building, e.g. B. the area of a building wall at the transition to the ceiling of a patio or loggia.

In the area of the corner 30 between the vertical outside and the downward-facing, horizontal outside of the thermal insulation 4, an angle strip 32 according to the invention made of plastic is provided. The angle bar 32 consists of two parts, namely one

Base body 34 with a longitudinal projection 36 on the outside at the angle apex, and a supplementary bar 38 placed on the outside on the longitudinal projection 36. The

Angle bar 32 has two legs 40 which have a 90 ° angle form with each other and are attached to the outside of the corner 30 of the thermal insulation 4, for. B. by means of an adhesive mortar or filler.

The supplementary strip 38 has a hollow square cross section, with a corner corner missing as it were. As a result of the open channel cross section formed in this way, the supplementary strip can be snapped onto the longitudinal projection 36 and is then positively fixed there. It is understood that the open side of the channel cross section is narrower than the diagonal of the square cross section of the longitudinal projection 36.

A glass silk fabric section 42 is clamped between the longitudinal projection 36 and the supplementary strip 38. This is, analogous to the embodiment of FIG. 1 ', together with overlapping glass silk fabric with a filler on the

Thermal insulation 4 attached. As in the embodiment of FIG. 1 ', there is a plaster layer 28 thereon.

The supplementary strip has a leg 44 which projects downward in the installation position shown. Analogous to the exemplary embodiment of

Fig. 1 'the leg 44 does not protrude exactly vertically downwards, but is positioned slightly obliquely towards the building. It forms a drip nose for water, so that the underside of the seat cover is not contaminated by rainwater and does not suffer any moisture damage.

It is understood that the angle rail 8, the outer bar 14, and the angle bar 32 have a constant profile over their length, so that the described legs and the longitudinal projection 36 extend in the longitudinal direction of the bar. The invention and embodiments of the invention are explained in more detail below with reference to an exemplary embodiment shown in the drawing. Show it:

Fig. L "a house wall corner with an angle bar according to the invention in horizontal cross section;

Fig. 2 "part of the angle bar of Fig. 1" on a larger scale, also in cross section;

Fig. 3 "is a partial horizontal side view of the part of

Angle bar of Fig. 2nd

In Fig. 1, a house wall 2 is drawn with an outside corner 4. It can e.g. be an outside corner of an entire building or an outside corner at the transition into a window reveal. On the outside of the house wall 2, thermal insulation 10 is applied, which e.g. consists of polystyrene plates. Corresponding to the wall corner 4, the thermal insulation 10 has an external thermal insulation corner 12.

On the thermal insulation corner 12, an angle bar 14 made of plastic or metal is placed on the outside of the thermal insulation 10 and on the

Insulation 10 attached in a manner to be described further below.

The angle bar 14 extends along the thermal insulation corner 12 in the vertical direction. Apart from a longitudinal projection 16 to be described later, the angle bar 14 has a right-angled angle profile with two legs 18. On the outside, the angle bar 14 has, as it were, the longitudinal projection 16 on the angle apex, which in the embodiment shown has an essentially square cross-section and on a square corner in the main part of the angle bar 14 passes.

The longitudinal projection 16 consists of a core part 17 with a substantially square cross section, which is integral with the Legs 18 is extruded, and a supplementary part 19, which has a substantially hollow square cross section with a missing square corner.

On the angle bar 14 is a section of a net

Reinforcing material 28, preferably made of glass silk fabric, attached. The reinforcement material 28 is fastened in that it has been placed over the core part 17 and that the supplementary part 19 has then been snapped onto the core part 17 with the reinforcement material 28 interposed. The supplementary part 19 has an inner contour which is essentially adapted to the outer contour of the core part 17. In order to enable attachment to the core part 17, the supplementary part 19 is, as it were, open in the area of a square corner, that is to say designed as a channel-like profile. It goes without saying that this open side is less wide than the cross-sectional diagonal of the core part 17, so that the supplementary part 19 is snapped onto the core part 17 in a form-fitting manner by spreading during attachment and subsequent merging. In this way, the reinforcement material 28 is held clamped between the core part 17 and the supplementary part 19.

If a plaster layer 32 is to be applied to the thermal insulation 10, a first filler layer 34 is first applied to the outside of the thermal insulation 10, also in the area of the corner 12. Then the angle strip 14 with the section of the reinforcing material 28 attached to it Corner 12 pressed into the still smooth filler 34. In addition, the reinforcing material 28 is pressed into the still smooth filler 34. Then a second layer 35 of filler is applied from the outside over the reinforcing material 28. Due to openings 40 in the legs 18, the filler 34 or 35 can also the legs 18

It can be seen that the areas 44 of the angle bar 14, i.e. the two outer square sides of the supplementary part 19, which from the free end of

Longitudinal projection 16 from with the main direction of extension parallel to the Legs 18 run, together form the front of the longitudinal projection 16 and form trigger surfaces which allow the second filler layer 35 to be smoothed out comfortably. After the filler 34 and 35 has tightened or hardened, the plaster layer 32 is applied. With the plaster layer 32

Longitudinal projection 16 of the angle bar 14 completely covered.

The plaster anchoring structure with depressions on the front side of the longitudinal projection 16 can be seen in the enlarged representations of FIGS Grooves 50 and 52, the plastic of the angle bar 14 is pushed up a little in the area of the groove walls, which increases the roughness of the plaster anchoring structure.It is expressly pointed out that the plaster anchoring structure shown is only one of many possible ones a simple longitudinal corrugation of the areas 44 is required. What is important is the formation of such an uneven, preferably "rough" structure that there are optimal bonding conditions for the plaster layer 32 in the areas 44. In practice, the depressions in the areas 44 from the application of the second filler layer 35 have "received" filler. This is even advantageous for the plaster layer adhesion.

It should also be mentioned that the areas 48 of the supplementary part 19 of the angle bar 14, where the second filler layer 35 adjoins at the end, are corrugated in the longitudinal direction of the angle bar 14, so that there is a good bond with the angle bar 14. The areas 48 are less critical than the areas 44 because in the areas

44 the plaster layer 32 must be held against peeling at right angles to the surface plane.

It should also be mentioned that there are also plasters in which the filler 34 and 35 described is not required. In this case, only the angle bar 14 is attached to the eg by means of an adhesive mortar Insulation 10 attached; the reinforcing material 28 is embedded directly in the plaster layer 32. In both cases, the reinforcement material 28 forms a reinforcement for the plaster 32 and keeps it free from cracks even when there are large fluctuations in temperature. In the case of working without filler 34 and 35, the possible trigger edge function of the areas 44 is not used. Another option is to work with two layers of plaster on top of each other. Here you can again use the pull-off edge function of the areas 44.

It is understood that the angle bar 14 has a constant profile over its length, that is, both the legs 18 and the longitudinal projection 16 extend in the longitudinal direction of the angle bar 14.

Typically, the legs 18 are about 1 mm thick and in

1 about 10 to 50 mm wide. The legs 18 are slightly spread apart elastically. The reinforcement material sections are typically 10 to 15 cm wide in the horizontal direction in FIG. 1; further reinforcement material for the continued plaster layer 32 is connected in an overlapping manner.
