Inner corner profile strip for a polished smile

The object of the innovation is an inner corner profile strip for plastered surfaces, which in or on buildings with all re-entrant Corners can be used. The profile consists of a rigid, angled sheet metal body with legs Expanded metal for fastening in plaster. This means that there should be tension in the plaster when it sets and also later be recorded in the event of building vibrations.

Part of the innovation is to mass-produce the application To facilitate the production of inner corner profile strips through the special design of these strips. Because an application such lasts on a large scale have so far failed due to certain factors Defects that hindered both production and storage as well as installation at the place of use, i.e. the plastering corner;

These shortcomings should be addressed by a new design of the profile can be eliminated, with the Inneneek bar also at the same time as a guide profile for which adjoining plastered surfaces should be used «

There are known plaster profiles for protruding corners on buildings, as well as construction net strips in various designs for avoidance possibly occurring tensions in the plaster. As a makeshift, such construction net strips can also be bent at an angle It is also known, in the case of corner strips made of sheet steel with legs covered by the plaster, in order to avoid the formation of cracks to be formed in the plaster as expanded metal parts, on the plaster is resilient.

For inside corners there are also multi-angled profile strips made of rubber-elastic material, preferably Plastic, proposed, the two outer leg parts of which are perforated for resiliently holding the plaster connect to the corner side to web parts, the width of which determine the thickness of the plaster layer delimited by them and between which the actual corner profile lies "· You have it considered necessary either the corner part or

both of them to the openwork outer thighs leading web parts to absorb elastic deformations and to compensate for displacements of the walls always arched to train; ' But that was the reason that these profile strips for interior corners - apart from the manufacturing ones Difficulties of the wide openwork leg parts made of plastic - neither from the point of view of installation, have proven themselves from the point of view of manufacture and storage:

A bow-shaped headboard is not suitable anyway for an exactly right-angled inside corner, i.e. especially for the most common and most important design of such a corner, a rounded corner can never be used as a guide profile for adjoining flat surface transitions serve "· Because when plastering there is no reliable support for the devices with which the transition to the subsequent plastered surfaces is absolutely flat and should be made without any paragraph. And arched Web parts require an arched profile for each different plaster thickness with a special radius of curvature, are therefore far more expensive than straight from the point of view of production and storage Bars with rectangular attached Efachbarflachen, those without Difficulty and without special bending shapes with! Ease

can be completed at any time in the desired web width, i.e. plaster thickness, and adapted to the individual case.

These shortcomings will come in handy creating one all To be adapted to the plastering dimensions occurring and at the same time as a guide profile for plastering in absolutely cleanly Corners suitable profile strip helped that with an inside corner profile strip for plastered construction areas, consisting from a multi-angled strip, the two outer ones of which are perforated to hold the plaster in place Leg parts connect to the corner side web parts, the width of which corresponds to the thickness of the plaster layer delimited by them determine and between which the actual corner profile lies, according to the innovation, the leg parts of the sheet metal Profile strip are designed as expanded metal and that the corner profile itself, as well as the web parts on both sides, consistently have a straight, right-angled profile shape.

The inexpensive profile strip made of sheet metal makes it possible to use the easy-to-prepare streek metal for the leg parts holding the plaster possible and, as the tests have shown, takes any shifts that may occur and deformations flawlessly. It is consequently

of which, for compensation purposes, certain parts of the To shape the skirting profile arch-shaped? rather, the bar can serve as a guide profile for the plastered surfaces and can be adapted to any desired plaster thickness without additional effort. A uniform basic model of such Inside corner directional profile strip is then e.g. for a wet plaster thickness of 12 - 13 mm or for an economy plaster layer prepared to a lesser thickness, for which purpose at the transition point from the expanded metal handle to the abutting web part

end
rich / space is available for the setting of the resulting variants. The great advantage achieved in this way for storage is obvious;

An embodiment of the innovation is described with reference to the drawing. This shows in

Fig. 1 is a perspective view of a partially plastered using a straightening profile according to the innovation Internal corner of a masonry and

Fig. 2 is a plan view of this corner

The Eeken sheet metal profile 1 angled in the manner shown lies between the masonry 2 and the interior plaster 3i The profile

In the middle, the strip bears the right-angled part b, which forms the visible corner angle after plastering, wad. thus represents an absolutely clean re-entrant corner. Part b, the visible inner surfaces of which form a safe guide for the cleaning tools, can be covered with the rest of the wall surface with wallpaper if desired, or it can also be painted in the same shade as the plaster ·

This actual right-angled corner profile close the web parts a on both sides, the width of which is adapted to the plaster thickness provided in each case. The advantage of this is different The web parts to be trained high, as well as the surfaces of the inner angular part, are flat because the two connecting edges partly b being used at the same time as finishing edges for the plaster This is the most difficult In place of the wall plaster, a straight course of the same is guaranteed; The planing of the inside corner, which was previously necessary, is no longer necessary.

Finally, the expanded metal part c gives the profile a firm hold in the plaster without cutting through it adversely

The inner corner straightening profile after firing can be used once in the manner described above, vertically for inside corners use, but also horizontally at the point where Yifand plaster and ceiling plaster meet; So that's here too any risk of cracking is largely eliminated and a perfect run of the plastered surfaces is guaranteed
