Profile piece made of glass, wall produced by means of the same, and method and system for its Manufacturing

The invention relates to a profile piece made of glass, with an approximately U-shaped cross section, the use of the same for the production of a composite wall that can be used for constructions and in the building industry, and the method and the system for the continuous production of this profile piece.

It is already known to manufacture glass profiles, that is, long pieces, with a U-shaped cross-section, their base has a width which is considerably greater than the height of the legs adjoining this, which are flat

Ser-like profiles «are generally used to (rias walls, such as walls, roofs, pools, protective borders, to build. The profiles are then arranged next to one another and optionally nested with one another, the one another opposite legs of two adjacent profiles are either attached to each other or separated by a continuous seal. In all cases, inserting a Sealing between the legs or the union of the same by cementing, gluing or by means of a pressure on the Leg acting connection strip made of an elastic material difficulties and disadvantages.

The insertion under pressure of neoprene foam seals between the legs creates only one Sealing effect and no unifying effect. Such a seal, which can only be locked in place by being compressed can be easily torn off.

On the other hand, kittening is a lengthy and quite expensive process. To get good results putties must be used, which adhere firmly to the glass and retain their flexibility despite their aging.

Gluing the legs with the help of adhesives (of the silicone type) gives good results in terms of the connection and the tightness, but it is extremely expensive as a result of the price of these products and the care with which the gluing must be carried out.

The strips that exert only one pressure on the opposing legs of adjacent profiles are not sufficiently effective because their adhesion to the flat surfaces of the legs made of glass is insufficient.

Another disadvantage of the known glass profiles is the impossibility of using metal clips for their union to be used whose aging is more favorable · These clips adhere namely, not on the thighs in the desired manner, and when they exert a significant amount of pressure they generate too much frequent breaks in the glass during handling.

The applicant has found that it is possible to remedy these disadvantages and in particular the task of

3098H / 0766

Unification of the glass profiles and / or the seal between two adjacent profiles to solve when the shape the cross-sections of the currently known profiles, in particular their legs, is modified.

There is a major advantage of the invention therein, the union of the glass profiles by elastic metal clips without any significant risk of the profile breaking.

The glass profile according to the invention with about

TJ-shaped cross-section with one of two side legs The enclosed base is characterized in that at least one leg extends at its end along the relevant leg Has leg extending lateral projection.

This protrusion increases the rigidity

of the profile and its mechanical strength, but finds its full justification in the invention for the [considered Type of union intended for the formation of a wall.

According to a first preferred embodiment

becomes the projection of the leg by bending the end of the leg formed, which is inclined to this. The bend of the leg then expediently has two flat parallel surfaces which are at an angle of about 45 ° with the Form legs and are connected by a fire-polished rounding.

According to another embodiment, the projection at the end of the leg is formed by a bead, whose surface has the quality of fire polishing.

In these two versions, the projection is expediently directed towards the interior of the profile.

The profile so formed can have various shapes, with the legs, for example, perpendicular to the base lie or form an acute or obtuse angle with it, the legs also being parallel to one another, converging or are arranged diverging.

Regardless of the particular design of the profile according to the invention, the application of the invention on the production of a wall, e.g. a wall, a roof, a ceiling or a protective border, two adjacent projects

3098U / 076 b

file united with each other by means of a profiled clamp with resilient legs, which the projection of at least one comprising glass profiles, and preferably both.

Under these conditions, the lateral projections of the legs also form a holding means for the clamp resilient legs, which is placed on the projections and at least partially engages them.

Thanks to this training, the use of the glass profiles according to the invention enables simple and economical Manufacture of glass walls. The union of two side by side lying profiles through their legs is done by means of a profiled strip with resilient Legs, which act like a spring and are pressed on. The legs encompass the lateral projections of the adjacent ones Legs of the adjacent profiles and are held back by them. The putting on of the spring clip, which can be made of metal or plastic, can be done extremely quickly. There is also a major advantage of Invention is that the resilient clip fulfills the task of a joint cover and the production of the seal Wall guaranteed. It is therefore not necessary to cement or glue the profiles, although this is of course a technique can also be used ·.

According to an embodiment that proves to be special has proven interesting, the clip with resilient legs has roughly the cross-section of an omega and is made of Metal.

Experience has shown the unexpected result that there is no risk of such Brackets damage the glass profile when attaching them, if the fire polishing for the rounded part of the lateral protrusion of the thigh is maintained

The inventive method for formation a profile with a leg having a bend, in which the leg is directed towards the base, while the glass is in the state of a plastic ribbon, it is characterized in that the end of the Leg is bent laterally while it is still plastic

3098U / 0766

is whereupon the bend so formed during its cooling is held, preferably avoiding any material contact with the rounded end of the bend during cooling to maintain their fire polishing.

For the production of the second profile type, at

which the leg has a lateral bead, the end of the leg is heated again after straightening, wherein it is held laterally at only part of its height, so that it collapses, at least on the specific side, by local melting.

The system according to the invention for producing the profile with a bent leg with a device for straightening at least one leg when it is in a plastic state, is characterized by behind this device on at least one side of the runway intended for the belt an arrangement of Pairs of forming rollers having two cylindrical sections of different diameters which pass through a frustoconical bevel connected, wherein one role is encompassing while the other is encompassed.

The system according to the invention for producing a profile with legs provided with a bead a shaping device for straightening at least one leg, while this is in the plastic state, is characterized by burners, which at least one side of the leg are facing, and which are followed by pairs of cylindrical support rollers, the roller which is in relation lies on the leg on the same side as the burner, an annular groove to receive the by melting the end the leg has formed bead.

In Pig. 1 you can see a glass profile of the at A

first type according to the invention, ie a profile with bent legs. The profile A with an approximately U-shaped cross section has a base 1 with a width L of, for example, 262 mm, which is bordered by two perpendicular symmetrical legs 2 with a height H of, for example, 40 mm. Profile A, incidentally, also the ^{profiles with bulges below ^ k e} J3Di "DChenen profiles

made of tempered or unhardened glass, reinforced or unreinforced, transparent, translucent or colored in the mass. It can also be provided with thin coatings, which change its optical properties or give it special, e.g. mechanical or give electrical properties.

Öem according to one embodiment of the invention Each leg 2 has a lateral projection at its end 3, which faces the inside of the U and by a bend of the end of the leg 2 is formed obliquely to the plane of the same. That of the bend. 3 given inclination can have any value between a few degrees and 90 ° In the example under consideration, this inclination is p_ 45 °

In detail (FIG. 2), the bend 3

two flat parallel sides a-b and c-d, which are connected by a rounded b-d, which is one of the fire polishing Has the appropriate surface quality · This prevents the microcracks, where later breaks in the profile can start with its use.

The deflection of the bend 3 is dimensioned such that the tangent t parallel to the plane of the leg 2 (Pig. 2) at the rounding has a distance £ from the leg, which is e.g. a third of the profile thickness.

The bends 3, which are designed in this way and facing the inside of the U, increase the mechanical strength of the Profiles and enable the union of identical or similar profiles with the help of profiled brackets 4 (Fig. 2), the length of which is e.g. equal to that of profile A.

In the example of Figures 2 and 3, the bracket 4- is made of a band metal, for example 4/10 stainless steel mm thick. The clip 4 has a web 5 which is slightly concave outward in the rest position and is extended by two curved resilient legs 6, which terminate in a bend 6a forming an entrance, so that the bracket 4 has approximately the shape of an omega. The profile of the bracket 4 is determined so that at no time yours Placing on the bends 3 of the legs of two adjacent profile pieces (Figure 3) an inelastic deformation of their Profile occurs, in addition, the legs 6 of the

309814/07 66

Clamp 4 exactly against the inner surfaces c-d of the bends need to lay. For this purpose, the profile of the bracket 4 is determined by the value of the above distance £. The characteristic dimensions of bracket 4 is its height h and the radius of curvature £ of leg 6. The opening s. of bracket 4 depends on the type and dimensions of the spacers provided for the profile pieces A.

In the execution of Figure 3, the profile pieces A separated by spacers 7, which establish a distance £ between the adjacent legs 2 when the Brackets 4 are attached. The type and design of the spacers 7 depends on the type of connection of the profile pieces A, which also determines the material of the brackets 4.

In a protective enclosure, the outside of which is shown in Figure 4 at E, with the legs 2 after are directed from the outside, the spacers 7 »which are covered by the bracket 4 on the side of the bad weather, be discontinuous, as shown at 7a, 7b and so on. The clamp 4 is made of stainless steel, or of chromium-nickel, or of an alloy based on aluminum and magnesium. The parallelepiped spacers 7a, 7b are, for example, made of an elastomer such as neoprene with a Shore hardness of 40. The distribution of the spacers must produce a constant distance between the profile pieces A.

For a protective enclosure, the legs 2 of which are directed inwards (FIG. 5), the brackets 4 on lying on the inside, measured as a spacer 7 a continuous Strips can be used, while the brackets 4 can be made of aluminum. In this case there is the spacer 7 is preferably made of closed cell neoprene and is convenient with an atmospheric one Adhesive that can withstand aging. The entire wall is designed so that the spacers 7 after Put on the clamps 4 experience a flattening of e.g. 20 $.

In the embodiment of FIG. 6, the clamp 4 a has an inner rib 8 which is formed by a bend in its web 5 and extends approximately parallel to the legs 6. After the attachment of the bracket 4a forms the

Hip 8 a spacer for the legs 2, so that a flexible Seal becomes superfluous.

7 shows a modification of the embodiment

which the rib 8b of the bracket 4b has a small height and only serves to stiffen the base 5. This execution permitted not the omission of the spacers 7 »

In the embodiment of Fig. 8, the clip 4c is made of plastic, e.g. a relatively rigid one Polyvinyl chloride, and their legs 6 run into corrugated projections 6c, which a pressure on the surface c-d of the Bends 3 should exercise. The bracket 4c is provided with a central thickened rib 8c, which the task of a Separating piece met. The bracket 4c is intended to pass through the legs 2 Maintain friction and pressure.

In all cases, the clamp 4 is pushed onto the bends 3 of the adjacent legs 2 attached, their postponement is about that shown in Figure 2. The legs β open by elastic deformation and close again to the surfaces c-d, which resist their later tearing off. "Experience has shown that the surface finish of the rounded portion b-d any damage to the glass during attachment which prevents clamps, while there were previously concerns about using metal clamps with glass profiles «

The inventive profile pieces and clips can be used to produce walls for various purposes such as walls, roofs, ceilings, simple or double protective frames, skylights, etc. The application is due to the possibility of connecting the profile pieces with each other very simply, the seal being achieved by purely mechanical means.

Apart from the application examples of FIGS. 4 and 5, FIG. 9 shows an interesting embodiment with an opening Profile piece A ,, which of two identical profile pieces Ap » A, is bordered with the same profile, these profile pieces having a leg with a bend 2 and a straight leg 2a exhibit. A clamp of the type 4a of FIG. 6 with a separating bend 8 is attached to the leg 2, the one on the

3098U / 0766

Side of the leg 2a lying entrance of the clamp is straight, which allows their placement and their removal.

Pas profile piece A ₁ is pivotable at 11 about an axis coinciding with the axis of symmetry of its base 1. In the closure position of the Sohenkel 2a in the clip 4a of the arm 2 passes the profile piece A ₁ of Frofilstucks Α ", while the _1-borne clip from the leg 2 of the section A 4a the legs 2a of the section A overlaps. ·· j

To open it, it is sufficient to pivot the profile piece A ₁ about the joints 11.

In the second embodiment of the invention shown in FIGS. 10 to 16, the projections of the legs 2 of the ^ profile pieces B formed by lateral beads 12, which preferably, but not necessarily, face the interior of the profile piece, and their surface properties corresponds to the fire polishing. Just a thickness of the thigh 2 of 6 mm, the beads 12 can correspond to an additional thickness of 2 mm.

Pig.11 shows a profile piece B ₁ in which the loops 2b form an obtuse angle with the base 1, while Pig.12 shows a profile piece B «, the legs 2c of which form an acute angle with the base 1.

The Profilstüoke B ₁ and B «can like the

Profile pieces B combined with one another and arranged next to one another will. The profile pieces with inclined legs of the type shown in Pig. 11 and 12 can of course also be bent Leg ends are executed.

In all cases, the profile pieces of type B can be fixed with the help of profiled metal clips 13 (Fig. 13) are combined, which in relation to the beads 12 a comprehensive Have shape and can be attached by elastic deformation, being the beads of two side by side overlap lying profile pieces B. To facilitate the attachment of the clip 13, the ends of its legs form diverging ones Approaches 14.

In the embodiment of FIG. 13, the clamp 13 has a central separating rib 15.

If the profile pieces B in opposite directions

An S-shaped bracket 13a is also (Fig.15)

suitable for the connection of two profile pieces of type B ₁ arranged in opposite Lag®, with the outer sides of the legs 2 facing each other »

According to another variant embodiment of the invention (Mg.16), the bead 18 is formed with a fire-polished surface cleß leg 2 one opposite leg 2 at the same time head thickened outwards and inwards

In all cases, the beads 12 or 18 as well as the projections 3 prevent the pulling off of the connection spring clips provided for the profile pieces *

For the continuous production of profile pieces with bent legs of type A one can expediently use the system of FIG. This installation contains a table 21 on which the flat plastic glass ribbon is brought by two rollers 22, 23, the edges of the ribbon formed have a smooth, so-called fire-polished surface with a curved profile, since they do not come into contact with rollers 22 and 23 "in the table 21 is followed by a roller 24, which brings the glass sheet to an arrangement for forming the U, which curved ramps 25 to the high bending the legs 2 and a Abplattungswalze comprises 26 (FIG _e 18) which with the first roller 27 a drive roller assembly 28 cooperates. Forming rollers 29 with vertical axes are arranged on both sides of the roller 26, "which contribute to the shaping of the legs 2 which were previously bent up by the ramps 25",

Behind the thus formed assembly to form the U according to the invention are, each side of the set of orphaned 28 pairs of staggered shaping rolls 32 and 33 3I ₅ »34 is provided with a loose rotatable perpendicular axes.

Each of these rollers has two cylindrical portions 31a, 31c are separated with different diameters, "oak by a chamfer forming frusto-conical portion 31b, as well as the rollers 32a _t 32b, 32c; 33a, 33b, 33c; 34a, 34b, 34c. In the case of the wrapping rollers, which, in the case of a projection directed towards the outer side of the profile piece, lie on the outside of the set of rollers 28, the upper section 31a (or 33a) has a larger diameter than the lower section 31c (or 33c), while in the case of the on the inside lying wrapped rolls the reverse is the case, in which the sections 32a, 34a have a smaller diameter than the sections 32c, 34c

The frustoconical sections 31b, 32b

or 33b, 34b have an inclined position, which is that of the to be produced Bends 3 of the legs 2 corresponds to the inclined position of the bevels in the profile pieces A of FIGS 45 °, and their distance corresponds to the thickness of the leg 2 apart from the play.

As can be seen from Figs. 17 and 19, these are immediate formed behind the flattening roller 26 lying forming rollers so that the cylinder 32c of the wrapped roller 32 has a noticeably larger diameter than the cylinder 31c the wrapping roll 31 has. This arrangement has proven to be Proven favorable, as it has a large guide surface for the Leg 2 and the bend 3 of the profile piece results.

With the then coming roles 33, 34> of those For example, if three pairs are provided on each side of the roller set 28, the diameters of the cylindrical sections are expedient 33a and 34c are equal to one another, as are the diameters of sections 33c and 34a. In other words, the Roles of one and the same pair are the same, but arranged opposite one another.

The process for forming the profile piece with bent legs by means of the above attachment is the following

'. The glass sheet is of the table 21 with a temperature of the order of 850 ⁰ C and a speed of 2.2 to 2.4 meters in grö'ssenordnungsmässig

Minute and directed to a U through the parts 25, 26, 27, 29, while its temperature is between 800 and 750 ⁰ C. The straight leg 2 is at its end through the frustoconical sections 31b, 32b of the first forming rollers 31, 32 bent, while the temperature of the glass is of the order of magnitude from 750 to 70O ⁰ C, which corresponds to a fairly low viscosity. It is found that the frustoconical surfaces in question avoid any material contact with the rounded portion bd of the bend, so that the fire polishing is maintained.

The other pairs of rollers 33, 34 should the. Hold leg 2 and its bend 3 until the viscosity of the glass is sufficient to prevent any collapse. Beyond the last pair of rollers 33, 34, the temperature of the profile piece is approximately between 700 and 65O ⁰ C.

Of course, the forming roller pairs are characterized by their lateral positions and height, as well as by the mutual arrangements (enveloping roller / enveloped roller), the shape of the profile piece to be produced and the sense of the lateral projection in relation to the plane of the leg (towards the inside or outside of the 21 shows the arrangement of the forming rollers 35, 36 for profile pieces A. with diverging legs with an inwardly directed projection. 22 also shows the arrangement of the rollers 37, 38 for the production of profile pieces A, with converging legs, the projection formed by a bend being directed outwards in relation to the plane of the leg 2.

To produce a profile piece with an inner bead of type B, the one shown in FIG. 17 is used, in which the same parts are denoted by the same reference numerals are. Behind the arrangement 25, 26, 27, 29 for forming the U, the system has rows of burners 41 (FIG. 24), which so against the rounded edge of the leg 2 and the inside of the same are directed that they have a superficial Produce melting of this edge immediately in front of the holding roller pairs 43, 44. The outer rollers 43 (Fig.25) have smooth

309814/0766

Flanks, while the inner rollers 44 at the level of the through the local melting of the leg 2 formed bead 12 have a circular arc-shaped annular groove 45. In this way three pairs of rollers 43, 44 are staggered along the set of rollers 28. These roles hold the leg 2 directly under the bead 12, defining the shape of the same.

When shaped profile pieces of the type of Pig.16 are to be, of course burner rows 41 must be provided on each side of the plane of the legs 2, and also the outer rollers 42 with a groove like the rollers 44 must be provided.

If the bead is to be formed on the outside of the leg, the burners 41 and the grooved rollers 44 are arranged accordingly.
