Abstract

Disclosed is a cable network facade, the cable network of which is made of carbon or a composite material. The cable network and the facade elements lie in a single plane, resulting in a slim, visually appealing facade, both sides of which are accessible without restrictions, e.g. in order to clean the glass facade.

Description

Title: Rope net facade with ropes

Fiber composite material

description

Rope net facades consist of two groups of ropes that form a network of ropes. The ropes of the first group or first group of ropes are referred to in the context of the invention as "first ropes". They are usually aligned vertically, while the second ropes run horizontally and a network or grid with rectangular fields is created. The intersection of a first and a second rope is called the node

designated. According to the size of the fields

Facade elements, mostly made of glass, attached to the cable network. As a rule, the

Facade elements to the cable network in the area of Nodes, since in this way the connection between the facade elements to the vertically running first ropes and the horizontally running second ropes can be achieved with one component. It also stabilizes the rope network.

In known cable network facades, the cable network forms a first level and the facade elements form a second level. Both levels run parallel to each other - typically at a distance of about 5 to 10 cm.

This distance is undesirable for aesthetic, practical and economic reasons: one

Rope net facade requires a relatively large amount of space and

accordingly reduces the usable building area.

The rope network also offers areas of attack for

Dirt and colonization by spiders etc. and must therefore be cleaned regularly, which causes considerable effort. The rope network makes it difficult to access the facade elements from one side, which makes cleaning them difficult.

The invention is therefore based on the object

To provide cable network facade that meets the highest aesthetic standards, all building permit law

The requirements are sufficient and it is also easy to maintain and clean. This object is achieved by a

Rope network facade for a building comprising the features of claim 1, namely at least one group of the first

Ropes and facade elements, wherein the first ropes consist of one or more lamellae of a fiber composite material, the coulter being pretensioned by first ropes, and wherein the facade elements in the through the

Rope network spanned level are arranged.

The family of first ropes, which usually run in the vertical direction, are arranged and pre-tensioned in the joints of two adjacent panes or other facade elements. The facade elements are connected in the area of their (side) edges with a first rope each.

This can be done, for example, by gluing with silicone

respectively .

The pretension and tensile strength of the first ropes are selected so that wind loads or other loads that would cause the panes to bend are absorbed by the ropes and carried away into the surrounding structure. As a result, the deflection of the disks is reduced so much that the disks connected to the first cables according to the invention do not break even under wind loads.

This object is also achieved according to the invention - especially if the height of the facade is the selected one

Pane height exceeds - by a cable network facade for a building comprising the features of claim 2, namely at least one cable network of first ropes and second Ropes, facade elements and knot elements for

Introduction of the loads of the facade elements into the cable network, whereby the first cables and the second cables of the

Cross rope network in nodes, the first ropes and / or the second ropes consist of one or more lamellae or fiber bundles of a fiber composite material, and wherein the facade elements in the by

Rope network spanned level are arranged.

Due to the gravity acting on the facade elements, the first ropes are generally heavier than the second ropes. This can be compensated for by different load capacities of the ropes.

The first ropes (but also the second ropes) can be used as a single strand or as two parallel and

strands spaced from one another. If the first ropes consist of two strands, then the second ropes run between them at a distance

running strands of the first ropes.

A certain redundancy is created by dividing the first or second ropes into two or more strands. In addition, due to the symmetrical structure of the cable network, there are no bending moments in the nodes.

Due to external conditions or boundary conditions, load transfer in only one direction of the rope may be necessary or desirable. This can be done through different

Preload of the cable shares can be controlled individually. At least one coulter must be pre-tensioned in a defined manner.

In addition, it is possible, as it were, to insert the facade elements into rectangles formed by the network, so that the facade elements also in the plane of the

Rope network are arranged. This also eliminates the loads from eccentric load introduction, which result inevitably from a curtain-wall glass facade according to the prior art.

In other words, the first and second ropes run in the spaces or joints between the facade elements and node elements are arranged to connect the facade elements to the ropes. Optionally, an intermediate layer that is effective in terms of building physics, such as thermal insulation, can also be arranged there.

According to the invention, the first ropes can be divided into two strands. Between these two strands

the second ropes run. This results in a symmetrical structure of the rope network, with the result that all strands or ropes are loaded evenly.

Another advantage of the arrangement according to the invention can be seen in the fact that the facade elements are accessible from both sides without restrictions. In addition, the ropes of the rope network in the joints of the facade elements are protected from mechanical damage and attacks

Corrosive media and the best possible protection. Finally, the cable network facade according to the invention is very simple, it is easy to assemble; If necessary, individual facade elements can also be replaced.

In an advantageous embodiment of the invention, the node elements have a receiving surface, in which

The receiving surface is provided with a recess for each of the two strands of the first ropes, and one, preferably resilient, flap is arranged on one or two edges of the recess. The bouncy

trained tab allows the guarantee of a predetermined contact pressure for the adhesive and

thus guarantees a high quality of manufacture with simple handling.

The receiving surface is in the installed state of the

Node element aligned horizontally so that it is the "support surface" for two in the horizontal direction

offers facade elements arranged side by side. Between the two side by side in a horizontal direction

arranged facade elements run through the two strands of the first ropes. So that the strands of the first ropes cannot be injured or scratched by the recess in the area of the base plate, are to both

Resilient tabs formed on the sides of the recess, which effectively prevent the strands from kinking in the region of the base plate. The resilient tabs extend parallel to a longitudinal axis of the first ropes and protrude, preferably on both sides, beyond the receiving surface. Depending on the weight of the facade elements / panes to be placed, the resilient tabs can be selected in different lengths. As a result, the twists of the

Node element during assembly with one-sided

Load limited.

In order to effectively prevent kinking or an impermissibly high point load between the base plate and the horizontally running second cables, in a further preferred embodiment of the invention there is a tab on the underside of the base plate or one with a large one

Radius rounded projection formed. This projection lies on the horizontally running second ropes, so that the horizontally running second ropes are not kinked or in any other way at this point either

mechanically overstressed.

It has proven to be advantageous if a width of the receiving surface of the node element is less than or equal to a thickness of the facade elements. Then namely the node element according to the invention disappears, as do the first and second ropes in the joint between the

Facade elements and thus becomes almost invisible.

The node elements according to the invention are preferably made of an elastic plastic. As Manufacturing processes are suitable for example injection molding or 3D printing.

In the cable network facade according to the invention, the first and the second cables run in joints between the

Facade elements. These joints are preferably grouted with a permanently elastic sealing compound, such as silicone, so that the cable net facade according to the invention seals off an exterior space from an interior space. In addition, the ropes are enclosed in the silicone joint and thus protected from damage.

In addition, the grouting of the facade elements causes the first and second ropes running in the joints and the facade elements to be linear and not only

be connected to one another in a punctiform manner, as a result of which a uniform load transfer from orthogonal to the

Facade elements acting loads is achieved in the ropes.

In order to be able to connect the first and second ropes to a building, the ropes have means for fastening.

These means for fastening first and second ropes are fastened to a separate frame, a wall and / or a ceiling of a building.

In an advantageous embodiment, the fastenings are prepared with a possibility for adjusting the length and pretension of the ropes and for easy handling during installation. You can do this with a sleeve with an internal thread and a

Have a threaded ring with an external thread. This threaded ring can be screwed into the internal thread of the sleeve. The threaded ring forms a contact surface for end pieces on the ropes.

By turning the threaded ring more or less deeply into the sleeve, the position of the contact surface becomes high

set so that with their end pieces on the

Ropes on the threaded ring have the desired pretension.

In order to ensure the best possible power transmission between the means for fastening first and second ropes and the first and second ropes, the first and second ropes each have an end piece at their ends. The end pieces can have a through hole with a

Have inner cone and at least one clamping piece for clamping the ends of the slats in the inner cone. The

Connections between an end piece, usually made of metal, and a rope or strand of the glass facade according to the invention can be made using an inner cone and clamping pieces. However, others known from the prior art can also be used

End pieces are used in the ropes according to the invention.

In an advantageous embodiment of the invention, the end pieces have an internal thread for pretensioning the ropes.

The loose pre-assembled ropes are then replaced by a

Clamping screw that is in the internal thread of the end piece is screwed in, brought to the desired preload. Then the threaded ring is screwed into the sleeve until it rests on the underside of the end piece.

Then the clamping screw is unscrewed. The force exerted by the pretensioned ropes is thus transmitted to the sleeve via the end piece and the threaded ring.

The facade elements are usually made of glass,

for example, as double glazing with two, three or four panes of glass, as single-pane safety glass or as laminated safety glass. Of course, other facade elements can also be integrated into the cable network facade according to the invention. For example, composite panes made of glass and plastic (bulletproof transparent facade elements) or photovoltaic modules or translucent facade elements or opaque

Facade elements made of metal or other materials can be integrated into the cable network according to the invention.

Further advantages and advantageous configurations of the

Invention are the following drawing, the

Description and the patent claims. All of the features disclosed in the drawing, its description and the patent claims can be essential to the invention both individually and in any combination with one another.

Description of the embodiments

1 is a greatly simplified one

Embodiment of a cable network facade according to the invention shown. The cable network facade comprises a frame 101, which in this exemplary embodiment is irregular

Square is formed. First ropes 103, which run essentially vertically, and second ropes 105, which run essentially horizontally, are clamped in the frame 101. The first ropes 103 and the second ropes 105 form the rope network. Where the first ropes 103 and the intersect second ropes 105, nodes or nodes 107 are formed

Clarity provided only a node 107 with reference numerals.

The ropes 103, 105 are connected to the frame 101 by means of tensioning devices 141 and are generally prestressed.

The details of the anchoring of the first and second ropes 105 and 103 to the frame 101 are given later in FIG

Connection with Figures 9 to 11 explained in more detail by way of example.

As can be seen from the exemplary embodiment shown, not all of the first ropes 103 are aligned exactly vertically. The first ropes 103 are arranged in the manner of a group of lines, so that they do not have the same orientation. The same applies to the second ropes 105. Nevertheless, the first ropes 103 and the second ropes 105 form a rope network with right angles in the node at first approximation.

The first ropes 103 essentially carry that

Weight loads. The second ropes 105 contribute to absorbing wind loads or other loads acting orthogonally on the glass facade. Therefore, the loads of the first ropes 103 are usually higher than the loads of the second ropes. This can be achieved, for example, by the first ropes 103 being thicker than the second ropes 105. Another possibility is to divide the first ropes 103 into two strands 103.1, 103.2. These the second variant is somewhat more complex than the first

Variant and is therefore shown and explained below with reference to Figures 2 ff.

The first variant, in which the first ropes 103 consist of one strand, results from the second variant in that one mentally "omits" one of the two strands. Because the two variants are very similar, it is not necessary to explain the simpler first variant in detail; FIG. 12 shows an exemplary embodiment of a node element for the first variant.

Figure 2 shows an isometric view of a partial

cut node 107.

In Figure 2 it can be seen that in this

Embodiment the first rope 103 from two strands

103.1 and 103.2 exist. Each of these strands 103.1 and

103.2 comprises at least one lamella from one

Fiber composite, preferably made of carbon fibers. The strands 103.1 and 103.2 are arranged at a distance from one another. The gap between the two strands 103.1 and 103.2 is dimensioned such that a second rope 105 is in between

can be passed, which is also preferably made as a lamella made of a fiber composite material.

A node element 2 according to the invention is inserted into this node 107, which is formed by the two strands 103.1 and 103.2 of the first rope and the second rope 105. The node element 2 is explained in more detail below in connection with FIG. 8.

The node element 2 comprises a receiving surface 109 which is aligned parallel to the second cable 105 or

runs parallel to it. In order to explain the details of the node element 2, reference is made to FIG. The

Receiving surface 109 comprises two recesses (without

Reference numerals). The two strands 103.1 and 103.2 run through these recesses.

In order to prevent the strands 103.1, 103.2 from being overloaded or even kinked in the area of the recesses, there are tabs 3 on the receiving surface 109

educated. The tabs 3 are arranged so that they run parallel to two edges of the recess. The

Tabs 3 are preferably elastic and resilient. In particular, their cross-section decreases with increasing distance from the receiving surface. This ensures that where the strands 103.1 and 103.2 through the

Receiving surface 109 of the node element 2 are performed, no kinking of the former is possible. The tabs 3 are formed symmetrically to the receiving surface 109 in the illustrated embodiment; they extend in both directions beyond the receiving surface 109.

Similarly, are on the bottom of the

Node element 2 two tabs 4 formed. The tabs 4 are spaced from one another such that a horizontally running first rope 105 (see FIG. 2) between the Tabs 4 can be passed. The tabs 3, 4 ensure that the first and second ropes 103, 105 cannot be "injured" or damaged by the node element 2. Of course there are others too

Designs of the node elements 2 conceivable and possible. The node elements 2 serve to connect the facade elements to the ropes without damaging the ropes.

Because the node element 2 is placed on a second rope 105 from above, only on the underside of the

Node element 2 tabs 4 are provided.

It is clear from FIG. 2 that the node element 2 is pushed onto the second rope 105 from above and the two strands 103.1, 103.2 are guided through the recesses and the tabs 3.

Two further facade elements 111 can be placed on the receiving surface 109 of the node element 2 to the right and left of the strand of the first cables. This allows weight forces from the facade elements 111 into the

Node element 2 are initiated.

Direct contact between the lower edges of the

There are no facade elements 111 and the second rope 105. The same applies to the lateral edges of the facade elements 111 and the first ropes 103.

Of the facade elements 111, which are located above the second rope 105, only the rear pane is shown. The facade elements are usually in the form of laminated glass or insulating glass with at least one front pane and one rear pane and a frame

educated. The two facade elements 111 below the second rope 105 show both panes of the laminated glass. The front disks, not shown, as a

Laminated glass upper facade elements 111 are, like the rear panes shown in the upper part of FIG. 2, on the receiving surface 109 of the

Node element 2 turned off.

FIGS. 4a) and b) show sections along the line B-B from FIG. 3. In both sections, the second rope 105 and the facade element 111 designed as laminated glass can be clearly seen. The facade element 111 consists of two glass panes 5, which by an edge bond 6 in a manner known per se to form a laminated glass or one

Insulating glazing were put together.

In FIG. 4 b) a variant is shown in which a strip-shaped facade element 11 is located between the second rope 105 and two glass panes 5

Element 201 is arranged. The strip-shaped element 201 can be used to improve the thermal insulation. However, it can also only be used for optical / design purposes.

In the exemplary embodiment according to FIG. 4, the two glass panes 5 of a facade element 111 are the same

dimensioned. FIG. 5 shows an exemplary embodiment, in which the outer glass panes (on the left in FIG. 5) protrude slightly beyond the edge bond 6, so that the gap between the adjacent glass panes 5 is minimized. This reduces the visible joint.

The space between the facade elements 111 is made of a permanently elastic material, e.g. Silicone, filled. This results in a linear elastic adhesive connection between the ropes 103 and 105 and the facade elements 111. This connection is sufficiently firm to permanently attach the facade elements 111 to the

Rope network, consisting of the first ropes 103 and the second ropes 105 to connect. However, this connection is also sufficiently elastic to prevent deformations, for example due to wind loads or temperature-induced

To be able to compensate for changes in length, and thus to even out the load transfer on the ropes.

FIG. 6 shows a section along the line C-C through the exemplary embodiment according to the invention. This illustration shows, among other things, that the first ropes can consist of two strands 103.1 and 103.2. A distance between the strands 103.1 and 103.2 is dimensioned such that a first rope 105 (not

6) can be passed between the strands mentioned.

This rope network is symmetrical with respect to one

Plane of symmetry that runs parallel to the outer surface of the facade formed by the panes 5. The strands 103.1 and 103.2 are dimensioned and spaced from one another such that they disappear in the joint between the facade elements 111 and not over the

Project outside of the facade elements 111. In other words, the strands 103.2 and 103.1 are also enclosed on all sides by silicone or another permanently elastic woven fabric which fills the joint between the facade elements 111.

FIG. 7 shows a bottom view of one

Junction 107. This bottom view becomes

clearly that the first rope 105 runs under the node element 2. It is also clear that the two

Straps 4 secure the knot element 2 on the first or rope 105 against slipping. It is therefore not possible for the node elements 2 to slip off the second cable 105 even when exposed to the greatest wind loads or other forces.

The implementation of the strands 103.1 and 103.2 through the recesses in the receiving surface 109 of the node element 2 can also be clearly seen in FIG. 7.

The cable network, consisting of the first cables 103 and the second cables 105, has to be pretensioned before the glass or facade elements 111 are used.

At least one group of ropes 103, 105 must be pre-tensioned in a defined manner. Embodiments of such a pretension are shown with reference to FIGS. 9a, 9b and 10.

The two strands 103.1 and 103.2 end in an end piece 12 which has an inner bore with an inner cone 115 and an outer thread 121 (FIG. 9a) or an inner thread 117 (FIG. 9b). The strands 103.1 and 103.2 are anchored in the end piece 12. For this purpose, for example, gradient anchoring in a conical sleeve 115 is used in order to shape and shape the ends of the strands 103.1 and 103.2 by means of a casting compound in the inner cone 115

to be firmly anchored. In principle, all types of fastening or connection between the strands 103.1 and 103.2 and the end piece 12 according to the prior art can be used in the invention.

The frame 101 is designed as a rectangular tube in the exemplary embodiments shown in FIGS. 9a and 9b. A sleeve 10 is welded into the rectangular tube of the frame 101. The end piece 12 of the cable 103, 105 is inserted into this sleeve 10 from below. The end piece 12 has this

Embodiment a continuous external thread 121.

A threaded bolt (not shown) is screwed in from above as an assembly aid. By means of a hydraulic

Hollow piston press or another tensioning device, the rope can be stretched to the desired pretension. It may be of considerable length

go out, so that the final fixation can only be used after tensioning. To do this, either an internally threaded sleeve (123 in FIG. 9a) is screwed in from the clamping side until the collar 127 comes to rest on the welded-in sleeve 10, or alternatively - depending on

Accessibility - one beforehand via the end piece 12

pushed collar 13 from the rope side (in the figures from "below") rotated against the end piece 12. The adjusting ring 13 has a central stepped through opening, through which the end or head piece 12 of a first rope 103 or a second rope 105 can be passed. Split load transfer plates 13a are arranged between the end piece 12 and the adjusting ring 13. They are inserted into the collar 12 before it is screwed into the sleeve 10 and reduce the

Through opening of the adjusting ring 13 so far that the end piece 12 rests on the wedge plates 13a. As soon as the desired preload has been reached and the adjusting ring 13 has been rotated against the lower end of the end piece 12, the adjusting ring 13 takes over the transmission of the

Preload and the tensioning device, not shown, can be removed.

A first rope with the strands 103.1 and the strands 103.2 is shown in the drawing in FIG. 9a.

The rope 103 can, for example, by means of two

semicircular wedge plates (without reference numerals) are jammed in the inner cone 115 of the end piece 12. A similar construction is known from engine technology: there the spring plates are attached to the stem of a gas exchange valve with the help of two-part wedge plates. Another variant is shown in FIG. 9b. In this variant, a clamping screw 129, not shown, is used, which is screwed into an internal thread 117 at the upper end of the end piece 12. The tensioning screw 129 is passed through a hollow piston press (not shown) and relieved at the top thereof. By actuating the hollow piston press, the end piece 12 thus moves upward in FIG. 9b. This tensioning process is continued until the first rope 103 has the prescribed pretension. Then the adjusting ring 13 is turned into the internal thread of the sleeve 10 until it comes into contact with the end piece 13. Then the clamping screw is unscrewed from the internal thread 117; the end piece 12 is seated on the threaded sleeve 13a or the adjusting ring 13 and the tensioning process is ended. This tensioning process is carried out in succession with all first ropes 103 and all second ropes 105.

In order to prevent the strands 103.1 and 103.2 from being scratched or otherwise damaged on the threaded ring 13, an elastic damping element, similar to an O-ring, may be provided at the through opening of the threaded ring.

Below the frame 101, an aperture or

Cover strips 14 may be arranged. Seals 15 are provided in the cover strips 14, which ensure that the facade elements are guided in the frame 101 without constraint but with positive locking and weatherproof. It understands it goes without saying that such an end piece 12 can also be carried out in a comparable manner with a second rope 105 with only one strand or another rope structure.

FIG. 10 shows a section along the line A-A from FIG. 9b.

FIG. 11 shows an anchoring in the sleeve 10 in a solid construction. The load transfer from the sleeve 17 into the solid structure is carried out, for example, by means of head bolt anchors. The inside of the sleeve is of the same design as in the exemplary embodiment according to FIGS. 9 and 10.

FIG. 12 shows an exemplary embodiment of a

Node element 2 shown in the receiving surface 109 comprises only one recess (without reference number) through which a first rope 103 runs.

In order to prevent the first rope 103 from being overloaded or even kinked in the area of the recess, tabs 3 are formed on the receiving surface 109. The tabs 3 are arranged so that they run parallel to two edges of the recess. The tabs 3 are

preferably elastic and resilient. In particular, their cross section increases with increasing distance from the

Receiving area. This ensures that where the strands 103.1 and 103.2 are guided through the receiving surface 109 of the node element 2, the former cannot be bent. The tabs 3 are in the illustrated embodiment symmetrical to

Receiving surface 109 formed; they extend in both directions beyond the receiving surface 109.

Similarly, are on the bottom of the

Node element 2 two tabs 4 formed. The tabs 4 are spaced apart from one another such that a horizontally running first rope 105 (see FIG. 2) can be passed between the tabs 4. The tabs 3, 4 ensure that the first and second ropes 103, 105 cannot be "injured" or damaged by the node element 2.

Another is greatly simplified in FIG

Embodiment of a cable network facade according to the invention shown cut away. Only two horizontal traverses of the frame 101 are shown. A family of first ropes 103 is fastened between the cross members. The first ropes 103 are prestressed. In this exemplary embodiment, the cable network consists only of first cables 103.

In this embodiment, the

Facade elements 111 in the vertical direction from the lower to the upper traverse of the frame 101. Therefore, second ropes 105 are unnecessary.

The force transmission and transmission are with this

Embodiment as follows: The weight of the pane is transferred from the lower edge of the pane or the facade element 111 to the lower one

Transverse of the frame 101 transmitted. For this purpose, it is usually necessary to arrange intermediate pieces (not shown) between the pane and the frame; these are not shown.

Pre-tensioned first ropes 103 prevent bez.

Effectively reduce the deflection of the panes due to wind loads or other orthogonal loads on the glass facade. This makes it possible to hold extremely large panes securely and to design a visually very reserved and aesthetically pleasing facade. The washers can be in your dimension

according to the maximum producible dimensions. These are currently usually up to 18 m long and 3 m wide. An area of more than 50m ² is thus covered with one pane.

With regard to the anchoring of the first ropes 103 to the frame 101, what has been said in connection with FIGS. 9 to 11 applies accordingly.
