Detailed Description

The curtain wall element according to a first embodiment of the invention will be described first with reference to fig. 1 to 5, where fig. 1 is a cross-sectional view of the curtain wall element 10 according to the first embodiment, the cross-section being horizontally extendable in the mounted state of the curtain wall element 10; FIG. 2 is a cross-sectional view of the structural unit of the curtain wall component 10 of FIG. 1 formed of a first U-shaped channel 1 and a strip of material 3; FIG. 3 is a perspective view of the first U-shaped channel 1 of the curtain wall component 10 of FIG. 1, only a small section of which is depicted herein, and the complete first U-shaped channel may have a length in meters, such as about 3m or 4m; FIG. 4 is a schematic view of the steel framing 8 of the curtain wall component 10 of FIG. 1; and figure 5 is a partial schematic view of the curtain wall component 10 of figure 1 connected to a structural beam, not shown.

As shown in fig. 1 and 4, the curtain wall component 10 may include five first U-shaped channels 1 arranged side by side, in particular, parallel to each other, and two second U-shaped channels 2 extending transversely, the second U-shaped channels 2 being connected, e.g., welded, to the ends of the five first U-shaped channels 1. The

U-shaped channels

1, 2 may form a steel frame 8. The second U-shaped channel 2 can be of identical or different design than the first U-shaped channel 1, for example identical or different in cross-sectional shape and/or size. The thickness of the material of each

U-shaped channel

1, 2 may be, for example, 1mm to 5mm. The two outer first and second U-channels 1, 1 may have strips of material 3 on the outer legs and the inner three U-channels 1 may have strips of material 3 on the left leg 11 as shown in figures 1 and 2.

It will be appreciated that the steel frame may comprise other profiles than the

U-shaped channels

1, 2 with two internal beads 12. For example, any of the following exemplary scenarios are possible:

one of the five first U-shaped channels 1 is replaced by an i-steel;

the two second U-channels 2 are replaced by square steel tubes with closed cross-section;

any one or more U-channels 1, 2 with two internal crimps are replaced by a U-channel without internal crimps or a U-channel with only one internal crimp.

As shown in dashed lines in fig. 4, one or more internal, in particular at least one internal group of U-shaped channel sections 9 extending transversely between each two adjacent first U-shaped channels can be provided instead of or in addition to the two second U-shaped channels 2 extending transversely provided at the ends of the first U-shaped channels 1. Each set of U-shaped channel sections 9 may be in a straight line. Fig. 4 shows an example of a group of four such U-shaped channel sections 9, which can be connected to one another by welding to the adjacent first U-shaped channel 1.

As shown in fig. 2 and 3, the first U-shaped channel section 1 may have inward beads 12 opposite to each other at open sides thereof, respectively. The internal bead 12 may extend linearly in cross section. Alternatively, the inner bead 12 may also extend in a curved manner in cross section, for example in the form of a circular arc. The inner bead 12 may be inclined towards the bottom of the first U-shaped channel 1 or may be substantially parallel to the bottom, for example may form an angle of less than 90 °, preferably 20 ° to 80 °, for example 30 ° to 75 °, in particular 45 ° to 70 °, for example about 60 °, with the associated leg 11. As shown in fig. 3, the inside curl 12 may have distributed perforations 13 in its extension. These perforations 13 can be used for venting when concrete is poured into the cavity of the first U-shaped channel 1, so that the cavity can be filled with concrete.

As shown in fig. 1 and 2, at least a part of the U-shaped channels, preferably each first U-shaped channel 1 and optionally also each second U-shaped channel 2, can have a strip of material 3 fastened to one of its two legs 11. It is also possible that a part or all of the

U-shaped channels

1, 2 may be fixed with a strip of material 3 on both legs 11 thereof, respectively. The material strips 3 extend in the direction of extent of the associated U-shaped channels and have a lower thermal conductivity than the associated U-shaped channels in order to reduce the heat conduction, preferably to substantially prevent the formation of thermal bridges. The strip of material 3 may for example be made of wood, preferably orthogonal glued wood. Each strip 3 can form a structural unit with the associated U-shaped channel, which can be screwed and/or glued. The strip of material 3 may for example have a thickness of 5mm to 20mm, may have a width substantially equal to the height of the legs 11 of the U-shaped channel, and may have a length substantially equal to the length of the U-shaped channel.

The insulating material 4 can be arranged in the gap of the steel frame 8 with the material strip 3 or in the receiving space defined by the

U-shaped channels

1, 2 and the material strip 3. The heat insulating material 4 may be, for example, a heat insulating board, a foam material, or heat insulating cotton. In some embodiments, the insulation 4 may be thermoset polystyrene board or rock wool board. Depending on the thickness of the individual insulating material, one or more layers of insulating material can be provided in each receiving space. The insulating material 4 may be mounted to the steel frame 8 as a prefabricated component or may be foamed in place in the steel frame 8, for example. Advantageously, the thermal insulation 4 may be flush with the steel frame 8 on both sides of the steel frame 8. In some embodiments, the insulating material 4 may serve as a form when the concrete is poured.

When pouring concrete, on a first side of the steel frame 8, the concrete enters the cavity of the respective

U-shaped channel

1, 2 through the open side of the respective

U-shaped channel

1, 2, and a concrete cast 5 having a predetermined thickness may be formed above the first side of the steel frame 8. In an exemplary embodiment, the concrete casting 5 may have a thickness of 20mm to 60mm, for example, about 30 mm. A firm steel-concrete joint bearing can be formed by the concrete projection from the concrete casting 5 into the cavity of the respective

U-shaped channel

1, 2 and by the inward turned edge 12 of the respective

U-shaped channel

1, 2, which projects into the concrete. In an exemplary embodiment, each

U-shaped channel

1, 2 has the same cross-section and may have a height in the cross-section of about 30mm to 50mm, for example about 40 mm.

The curtain wall element may comprise a coating 6 which may be applied against the second side of the steel frame 8, in particular against the bottom of each

U-shaped channel

1, 2, and against the strip of material 3 and the insulating material 4. The cover 6 may be fixed to at least one of the steel frame 8, the strip of material 3 and the insulating material 4, and in particular may be fixed only to the strip of material 3. The cover layer 6 can be, for example, a thin wood plate or another suitable material, particularly preferably an aerosol insulation blanket. The aerosol insulation blanket has particularly good thermal insulation properties, light weight and small thickness. The aerosol insulation blanket can be easily and quickly bound to the strip of material 3 made of wood strands with a binding needle.

The thickness of the fa sigmaade component 10 according to the first embodiment may be substantially equal to the thickness of the concrete casting 5 + the height of the

U-shaped channels

1, 2 + the thickness of the cladding layer 6. In the case of a concrete casting 5 having a thickness of about 30mm,

U-shaped channels

1, 2 having a height of about 40mm and using an aerosol insulation blanket, the fa sigmaade element 10 may have a thickness of no more than 80 mm. Typically, curtain wall components known in practice may have a thickness of about 150mm or more. Curtain wall elements of about 120mm thickness have been counted as thinner curtain wall elements. According to the first embodiment of the invention and other embodiments, it is possible to realize a curtain wall element with a thickness of 120mm or less, in particular 100mm or less, for example 60mm to 90mm, for example 75mm to 85 mm; meanwhile, excellent heat insulation performance can be realized.

Typically, a rectangular curtain wall component 10 may have four side edges, which in the mounted state of the curtain wall component 10 may be referred to as an upper edge, a lower edge, a left edge and a right edge, wherein the upper edge and the lower edge extend horizontally and the left edge and the right edge extend vertically. The curtain wall element 10 may for example have a planar dimension of 2m x 2m or 2m x 3m or any other suitable dimension.

FIG. 5 depicts an enlarged partial schematic view of the mounting of the curtain wall component 10 on a structural beam according to the first embodiment. The curtain wall element 10 may be fastened to an upper and a lower structural beam, not shown, in the four corner regions by means of connecting structures as shown in fig. 5. At the bottom of the first U-shaped channel 1, there is a first opening, in which a bolt bushing 14 is welded, the bolt bushing 14 penetrating the covering layer 6. The L-shaped angle 15 welded to the structural beam has a second opening. The bolt 19 is screwed into the bolt sleeve 14 through the second opening and is fastened with the nut 18. For good thermal insulation properties, a first insulation mat 16 may be arranged between the angle 15 and the bolt sleeve 14; the second bore may have a larger diameter than the shank of the bolt so that the shank of the bolt does not contact the wall of the second bore; a second insulating mat 17 can be arranged between the angle 15 and the nut 18; the bolts 19 may have a thermal barrier coating.

FIG. 6 is a partial cross-sectional view of a curtain wall system in accordance with a first embodiment of the present invention. The curtain wall system may comprise two adjacent

curtain wall elements

10a, 10b according to the second embodiment of the invention. In fig. 6, the first curtain wall element 10a on the left shows a simplified partial cross-sectional view only in the end region on the right, and the second curtain wall element 10b on the right shows a simplified partial cross-sectional view only in the end region on the left. As can be seen from fig. 6, the two

curtain wall elements

10a, 10b according to the second embodiment may be constructed similarly to the curtain wall element 10 according to the first embodiment, with the main difference that: the

curtain wall components

10a, 10b additionally have

metal walls

7a, 7b; and the inner turn-up 12 of the respective U-shaped channel is substantially perpendicular to the associated leg 11, however, in a not shown embodiment the inner turn-up 12 can also be formed identically to that in the first embodiment. Otherwise the

curtain wall element

10a, 10b may be constructed the same as or similar to the curtain wall element 10 according to the first embodiment, and reference may therefore be made to the description for the curtain wall element 10 according to the first embodiment.

In the curtain wall system as shown in fig. 6, the first curtain wall component 10a on the left has a metal apron 7a on the vertically extending right edge, and the second curtain wall component 10b on the right has a metal apron 7b on the vertically extending left edge. The

side walls

7a, 7b can be fixed to the adjoining first U-shaped channel section 1 before the concrete is poured, for example by welding or riveting, for example by blind rivets. For this purpose, the

side walls

7a, 7b can have a web 23 projecting from the inner surface of the side wall body 24, the section of the side wall body 24 that is inside the web 23 in the thickness direction of the curtain wall component can rest on the leg 11 of the outer part of the first U-shaped channel 1, and the web 23 can rest on the inner bead 12 bent from the leg 11 of the outer part.

The

apron

7a, 7b can have external ribs 21 projecting from the external surface of the apron body 24. The external rib 21 may extend continuously over the length of the respective counter body 24, or may comprise a plurality of external rib sections disposed distributed over the length of the respective counter body 24.

In the thickness direction of the

curtain wall components

10a and 10b, the outer ribs 21 of the

side walls

7a and 7b may be staggered with each other, the two side wall bodies 24 and the two outer ribs 21 may form a first accommodating space for accommodating the sealing rubber strip 25, the two side wall bodies 24 and the outer ribs 21 may form a second accommodating space for accommodating the curtain wall structural rubber 26, and the outer ribs 21 form the boundary of the first accommodating space and the second accommodating space. The sealing strip 25 can be made of EPDM, for example. The curtain wall construction glue 26 may be made of silicone, for example, and may be extruded into the second receiving space and may form a weather-resistant, waterproof seal after curing.

In a first version of the first embodiment of the curtain wall system, the vertically extending left edge of the first curtain wall component 10a may have a ledge 7b as shown in fig. 6, and the vertically extending right edge of the second curtain wall component 10b may have a ledge 7a as shown in fig. 6. The first curtain wall element 10a and the second curtain wall element 10b may be identically constructed.

Furthermore, the horizontally extending upper and lower edges of each

curtain wall component

10a, 10b may have a

reveal

7a or 7b as shown in fig. 6. For example, the left and upper edges of each fa sigmaade

component

10a, 10b may have a ledge 7b, while the right and lower edges of each fa sigmaade

component

10a, 10b may have a ledge 7a.

Furthermore, the horizontally extending upper and lower edges of each

curtain wall component

10a, 10b may have a

reveal

7a or 7b as shown in fig. 6. For example, the four side edges of the first curtain wall component 10a may each have a reveal 7a, while the four side edges of the second curtain wall component 10b may each have a reveal 7b; or the left and right edges of the first fa sigmaade component 10a may have a ledge 7a, the upper and lower edges may have a ledge 7b, and the left and right edges of the second fa sigmaade component 10b may have a ledge 7b, the upper and lower edges may have a ledge 7a.

In a third version of the first embodiment of the curtain wall system, the left and right edges of each

curtain wall component

10a, 10b have a

ledge

7a, 7b; the upper and lower edges have no perimeter walls, or perimeter walls respectively, but these have no external ribs on the external surface.

As shown in FIG. 6, the

rails

7a, 7b may additionally have internal ribs 22 extending from the interior surface of the rail body 24. These internal ribs are embedded in the concrete casting 5. The internal ribs 22 may extend continuously over the length of the respective lasting body 24, or may comprise a plurality of internal rib sections disposed distributed over the length of the respective lasting body. Said internal ribs 22 may facilitate the firm connection of the

coamings

7a, 7b with the concrete casting 5, and may contribute to the waterproofing properties of the curtain wall element. Possible penetrating moisture cannot easily pass over the inner ribs 22 to the side of the fa sigmaade

component

10a, 10b facing the room. The internal ribs 22 may be inclined towards the inside of the

curtain wall component

10a, 10b, for example the internal ribs 22 may form an angle of ≦ 70 ° with the lasting body 24.

Each

curtain wall component

10a, 10b may be connected at the upper and lower edges with another curtain wall component or a transversely extending structural beam or floor slab and may form the same or similar sealing structure as between the first and second

curtain wall components

10a, 10b. As an extension, the first curtain wall element 10a on the left edge and the second curtain wall element 10b on the right edge may be connected with further curtain wall elements or vertically extending structural beams and may form the same or similar sealing structure as the one between the first and second curtain wall elements.

Two

adjacent counter walls

7a, 7b may, for example, have a spacing of 10mm to 20mm, for example a spacing of approximately 15 mm. The dimension of the outer rib 21 in cross-section is smaller than the distance between two adjacent fa sigmaade elements, preferably may be larger than half the distance, for example may be about 2/3 of the distance. The spacing of the outer ribs 21 may for example be smaller than the spacing of two adjacent curtain wall elements, for example between 1/3 and 3/4 of this spacing, optionally between 1/2 and 2/3 of this spacing. In case the pitch of two adjacent curtain wall elements is about 15mm, the pitch of the outer ribs 21 may be 6mm to 12mm, alternatively 8mm to 10mm. The thickness of the sheet material of the

rails

7a, 7b may be, for example, 1mm to 3mm, for example, about 2mm. The inner ribs 22 may have a similar size in cross-section to the outer ribs 21.

In the cross-section of the fa sigmaade

component

10a, 10b as shown in fig. 6, the concrete casting 5 may have a thickness of about 30mm, and the height of the

highwall

7a, 7b or highwall body 24 may be slightly greater than the thickness of the concrete casting 5, for example about 35mm.

The free edge of the web 23 of the

highwall

7a, 7b may be substantially aligned with the free edge of the internal bead 12, for example, may have a dimension in cross-section of about 2mm to 4mm. In the case of an inclined design of the inner bead 12 as shown in fig. 2, the web 23 can be correspondingly inclined and rests on the inner bead 12.

Fig. 7 shows a simplified partial cross-sectional view of a curtain wall system according to a second embodiment of the invention. The embodiment according to fig. 7 can differ from the embodiment according to fig. 6 only in the

metallic ribs

7c, 7d of the curtain-walling

units

10c, 10d, and therefore fig. 7 is described more simply than fig. 6, only the two

ribs

7c, 7d and the two associated first U-channels 1 of the curtain-walling

units

10c, 10d being described in fig. 7, while the other components as described in fig. 6 are omitted in fig. 7.

The curtain wall system may comprise two adjacent

curtain wall components

10c, 10d according to the third embodiment of the invention. The

curtain wall elements

10c, 10d according to the third embodiment may be constructed similarly to the

curtain wall elements

10a, 10b according to the second embodiment, with the difference mainly in the metal mantles 7c, 7d of the

curtain wall elements

10c, 10d, and in other respects the

curtain wall elements

10c, 10d may be constructed identically or similarly to the

curtain wall elements

10a, 10b according to the second embodiment.

In the curtain wall system as shown in fig. 7, the first curtain wall component 10c on the left has a metal apron 7c on the vertically extending right edge, and the second curtain wall component 10d on the right has a metal apron 7d on the vertically extending left edge.

The

coaming

7c, 7d can each have a coaming body 24 that surrounds the concrete casting 5 and two external ribs 21 that project from the outer surface of the coaming body 24. Each external rib 21 may extend continuously over the length of the respective highwall body 24, or may comprise a plurality of external rib sections disposed distributed over the length of the respective highwall body 24.

All the external fins 21 of the two

banks

7c, 7d are staggered with respect to each other in the thickness direction of the curtain wall element. The two lasting bodies 24 and the total of four outer ribs 21 may form a labyrinth-type first accommodation space for accommodating the sealing rubber strip 25, and the two lasting bodies 24 and the outermost outer rib 21 may form a second accommodation space for accommodating the curtain wall structural adhesive 26, wherein the outermost outer rib 21 forms a boundary of the first accommodation space and the second accommodation space.

In a first version of the second embodiment of the curtain wall system, the vertically extending left edge of the first curtain wall component 10c may have a ledge 7d as shown in fig. 7, and the vertically extending right edge of the second curtain wall component 10d may have a ledge 7c as shown in fig. 7. Two adjacent

curtain wall elements

10c, 10d may be of identical construction.

Further, the horizontally extending upper and lower edges of each

curtain wall component

10c, 10d may have a

ledge

7a, 7b, 7c, 7d as shown in fig. 6 and 7. For example, the left and upper edges of each fa sigmaade

element

10c, 10d may have a reveal 7c, while the right and lower edges of each fa sigmaade

element

10c, 10d may have a reveal 7d.

In a second version of the second embodiment of the curtain wall system, the vertically extending left edge of the first curtain wall component 10c may have a ledge 7c as shown in fig. 7, and the vertically extending right edge of the second curtain wall component 10d may have a ledge 7d as shown in fig. 7.

Further, the horizontally extending upper and lower edges of each

curtain wall component

10c, 10d may have a

ledge

7a, 7b, 7c, 7d as shown in fig. 6 and 7. For example, the four side edges of the first curtain wall component 10c may each have a ledge 7c, while the four side edges of the second curtain wall component 10d may each have a ledge 7d; alternatively, the left and right edges of the first fa sigmaade element 10c may have a ledge 7c, the upper and lower edges may have a ledge 7d, and the left and right edges of the second fa sigmaade element 10d may have a ledge 7d, and the upper and lower edges may have a ledge 7c.

In a third version of the second embodiment of the curtain wall system, the left and right edges of each

curtain wall component

10c, 10d have

ledges

7c, 7d; the upper and lower edges have no perimeter walls, or respectively, but these have no external ribs on the external surface.

As shown in fig. 7, the

highwall

7c, 7d may additionally have internal ribs 22 projecting from the internal surface of the highwall body 24. These internal ribs 22 are embedded in the concrete casting 5.

In an embodiment not shown, the ledge may have two or more internal fins staggered in the thickness direction of the curtain wall element, in a cross section of the curtain wall element.

FIG. 8 shows a simplified partial cross-sectional view of a curtain wall system according to a third embodiment of the present invention. Fig. 8 is a view corresponding to fig. 7 but more simplified, and in fig. 8 sealing means similarly constructed as in fig. 7 are also omitted. This embodiment may differ from the embodiment as shown in fig. 7 mainly in that the two outer ribs 21 of the two adjacent highwalls 7e, 7f of the two

curtain wall elements

10e, 10f according to the fourth embodiment, which are internal in the thickness direction of the

curtain wall elements

10e, 10f, are aligned with each other.

The

highwall

7c, 7d, 7e, 7f shown in fig. 7 and 8 can be similar in terms of dimensioning to the

highwall

7a, 7b. For example, the external and internal ribs of the

highwalls

7c, 7d, 7e, 7f may have the same or similar dimensions in cross section as the external and internal ribs of the

highwalls

7a, 7b.

In an embodiment not shown, the curtain wall elements may constitute a curtain wall system on either side edge with an adjacent building element, which may be, for example, a transversely extending structural beam, a vertically extending structural column, or a floor panel. The building element may have components that are similarly configured to the rails of the curtain wall element, and thus, a sealing structure between the curtain wall element and the building element may be formed that is the same as or similar to the sealing structure between two adjacent curtain wall elements.

Fig. 9 is a cross-sectional view of a curtain wall element 20 according to a fifth embodiment of the invention. The curtain wall component 20 may be constructed the same as or similar to the first embodiment in terms of the steel frame 8, the strip of material 3, the insulating material 4 and the cladding 6. For the sake of brevity, no description is repeated, and reference may be made to the relevant description for the first embodiment.

Unlike the first embodiment, in the fifth embodiment, the marble plate material 31 is dry-hung on the first side of the steel frame 8. The steel frame 8 may additionally comprise a plurality of cross beams 32, which cross beams 32 extend transversely to the direction of extension of the first U-shaped channel 1 on a first side of the steel frame 8. As shown in fig. 9, each cross member 32 may extend over the respective first U-shaped channel 1. The spacing of the cross beams 32 may depend on the size of the marble slab 31. The cross member 32 can be connected to the respective first U-shaped channel 1 via an angle 33, for example, the cross member 32 is welded to the angle 33, and the angle 33 is welded to the associated first U-shaped channel 1. The angle 33 can be arranged laterally to the associated first U-shaped channel 1. The marble plates 31 may be connected to each other and/or fixed to the cross member 32 by a connecting means 34. In addition, a sound insulating material, such as soundproof cotton, may be additionally accommodated in the cavity of each

U-shaped channel

1, 2 to improve the sound insulating performance of the curtain wall member 20.

Fig. 10 is a cross-sectional view of a curtain wall component 30 according to a sixth embodiment of the invention. The curtain wall component 30 may be constructed the same as or similar to the first embodiment in terms of the steel frame 8, the strip of material 3, the insulating material 4 and the cladding 6. For the sake of brevity, no description is repeated and reference may be made to the description relating to the first embodiment.

Unlike the first embodiment, in the sixth embodiment, the marble plate material 31 is dry-hung on the first side of the steel frame 8. The steel frame 8 may additionally comprise a plurality of cross beams 32, which cross beams 32 extend transversely to the direction of extension of the first U-shaped channel 1. As shown in fig. 10, each cross member 32 may extend between two adjacent first U-shaped channels 1. Advantageously, the cross beams 32 can be divided into a plurality of groups, each group comprising a plurality of cross beams 32 aligned in a direction transverse or transverse to the direction of extension of the first U-shaped channel 1. In the exemplary embodiment shown in fig. 10, each set includes four short beams 32. Since the cross beams 32 do not extend beyond the first side of the steel frame 8, the marble plate 31 may abut the steel frame 8, and thus the curtain wall member 30 may have a significantly thinner thickness than the fifth embodiment. The cross member 32 may have two legs at its two ends, which are connected to the adjacent first U-shaped channel 1 or strip 3, respectively. The marble plates 31 may be connected to each other and/or fixed to the cross member 32 by the connection means 34.
