Description

The invention relates to a component and its use and a method for producing a component.

Such components can also be used for sound insulation. Then corresponds the cold area or the warm area of the rooms between which the sound insulation is to be made.

A generic component is known from EP 117 308 A. Here however, there is a strong heat transfer from the warm area to the cold area in front.

Furthermore, the German utility model DE 296 10 652 U1 is known. In this component, a carrier is in a plastic hollow chamber profile arranged, which consists of metal and plastic. The order this carrier within the plastic hollow chamber profile shows that the Beam between the outside of the window element and the inside of the window element is arranged such that a carrier part the cold outside area and another support part which is usually warmer Inner part is facing. In between is a molded plastic part that reduces the heat transfer from the inner support part to the outer support part. The metal outer and inner support parts ensure sufficient Stability and the plastic molding in between is from cold-rolled inner or outer support part held so that a one-piece support element made of two different materials.

This well-known reinforcement profile for hollow plastic profiles ensures that the heat transfer values on the window frame are greatly reduced can. However, the production of the reinforcement profile is relatively complex, because different materials have to be bonded together in such a way that there is sufficient stability even with large differences in heat can be guaranteed.

It is also known from EP-A-0 553 688 to reduce the heat transfer through a steel profile as large as possible the connection between the outer and inner side of the profile. Since this inevitably comes at the expense of stability, struts provided that hold the inner and outer support part together, so that the structural requirements are met can. The proposed large-scale material removal and hereby accompanying structural weakening of the profile can however exist Security reserves, especially for dynamic loads, considerable to reduce.

The present invention is therefore based on the object of a component to develop with a support that is used as a hollow section reinforcement is suitable and on the one hand is inexpensive to manufacture and on the other hand, with only a slight loss of stability, a good reduction of the Causes heat transfer.

This solves this task. that the carrier between the outer Carrier part and the inner carrier part offset from one another Has rows of holes and the carrier from a single component, namely Steel is made, the carrier within a Hollow chamber of the hollow chamber profile as Reinforcement is arranged.

The component according to the invention thus has a carrier which is made from a single material, such as rolled steel sheet, and nevertheless has significantly reduced thermal conductivity properties. This is achieved in that the heat-conducting cross section of the carrier has the rows of holes. The heat-conducting path is extended so much by the offset holes that the heat transfer is considerably restricted without the stability being particularly affected.
The carrier of the component according to the invention is thus made like a conventional conventional carrier from a single material, such as steel, and the heat transfer is not reduced by another part of the carrier, but by a special shape of the carrier itself. The shape of the carrier can be during the manufacture of the carrier or thereafter can be changed inexpensively in a simple manner without increased costs arising from the joining together of different materials. In addition, there are no problems in the joining area between different materials in the component according to the invention, even if the temperatures in the facade area fluctuate greatly and the material used is subject to extensive expansions and shrinkages.

Since hollow plastic profiles are usually produced using the extrusion process due to smaller variations in mold making is a change in To achieve shaping of the hollow chamber profile inexpensively. this makes possible it to arrange lugs or webs in such a way within the hollow profile that these lugs or webs hold the wearer.

It is advantageous if the rows of holes arranged offset to one another in the Area of the neutral fiber of the carrier. Every carrier has dependency areas affected by its type of load more and less heavily. Alternating loads often occur, especially with facade elements on the carrier, which particularly affect the edge areas of the carrier, while a carrier area in between is stressed far less. In this area lies the neutral fiber, and it is suggested to be straight arrange the rows of holes in this area to ensure the stability of the beam to reduce as little as possible.

It is advantageous if the carrier passes outside the neutral fiber Multiple laying of a sheet metal part is reinforced. The sheet metal part preferably has a thickness of more than 0.5 mm.

A simple creation of the rows of holes is made possible by material removal. For this purpose, the holes can be in the area of the neutral, for example Fiber drilled or punched out. The holes are also preferred arranged so that only small bridges remain between them. The bridges are sufficient for the required strength, but they reduce the heat transfer considerably.

Especially when using cold-formed sheet metal can also be used as Base material used for the manufacture of the carrier is a perforated plate become. Such a sheet has a reduced one in the entire sheet area Strength. However, this can be due to the shape of the carrier and in particular through the parallel arrangement of several sheet metal layers in more heavily loaded carrier areas are balanced. Thus remains in a limited, heat-conducting cross-sectional area is preferred single-layer perforated sheet, while in the adjacent areas the deformation of the sheet higher stability values can be achieved.

Alternatively or additionally, the rows of holes can also be formed by material deformation be generated. Certain cuts or punchings on the carrier allow carrier areas to be pushed out of the carrier plane in order to To reduce heat transfer.

Especially in the production of facade elements such as windows or between the windows it is advantageous if the outer and the inner support part preferably by at least one nose or at least one web is attached to the hollow chamber profile. This allows it to hold the carrier without using additional parts. There the hollow chamber profile is usually made of plastic and thus has a smaller heat transfer coefficient than a steel beam, the attachment to the hollow chamber profile leads to a sufficient hold and at the same time to isolation.

A preferred application of the component according to the invention is used as a window frame part or window sash part. in this connection the beam lies between a colder outside of the facade and a warmer one Facade inside, so that the training according to the invention is optimal can reduce the heat transfer between these sides.

A preferred embodiment variant provides that the component has two Has hollow chamber profiles and the carrier is arranged between them. This leads to the fact that the carrier is arranged outside the hollow chamber profiles but is protected by the hollow chamber profiles provided on both sides is. The carrier has on the one hand a static function as Supporting element and on the other hand a function as a coupling between the Hollow chamber profiles through the connection between the two hollow chamber profiles and the carrier arranged in between arises. Advantageous it is when the carrier has a shape that enables an insulation element to position. The inside of the carrier can be covered with a Insulation material can be foamed. However, according to the invention provided that an insulation molded body is inserted into the carrier in this way is that it is positioned by the position of the wearer. Position under is a determination of the position of the insulation body, relative to Carrier, while maintaining a longitudinal movement of the Wearer, understood. Depending on the requirements, there may also be a movability of the insulation body in the longitudinal direction of the carrier through which Shaping the carrier can be prevented.

The positioning described can be done in a simple manner achieve that the carrier three arranged at right angles to each other Has areas. These three surfaces allow, on the one hand, an insulation body easy to insert in the carrier and on the other hand the position of the insulation body through the shape of the carrier set.

By positive or non-positive connection between the sides of the wearer and the insulation body, the insulation body becomes more or less firm with connected to the carrier.

The object on which the invention is based is also achieved by the use of such a component, as an insulation element between a cold area and solved a warm area, the carrier in the area of its neutral Fiber has staggered rows of holes.

In a method according to the invention for producing a component, in which a carrier is formed from a sheet and by one or several plastic profile parts are surrounded by When the sheet is formed, rows of holes offset from one another are introduced. The invention Beams are advantageously made from a cold-rolled Made of sheet metal. During this molding process or immediately before or afterwards it is possible to introduce the hole ranges according to the invention. This allows the molding step to be combined with the Arrangement of rows of holes to connect. The manufacture of such Carrier is therefore only slightly more expensive.

A particularly favorable way of producing a carrier according to the invention is that a perforated sheet is used as sheet metal. this makes possible keeping the manufacturing process unchanged. Through the Use of the perforated plate is in the connection area between the inner part and the outer part of the heat-conducting cross-sectional area reduced without further measures being necessary.

The carrier 1 shown in FIG. 1 has an outer carrier part 2 and one inner support part 3, which are interconnected by a web 4. The outer support part 2 is a colder when installed Cold area 5 and the inner part of a generally warmer warm area 6 facing. The web has a screw channel in the present case 7 on and on both sides of this screw channel are continuous, offset from each other arranged elongated holes 8 are provided, which lie in the web 4 Reduce the heat-conducting cross-section. They are also for reduction the heat transfer also provided on the outer support part elongated holes 9, the heat transfer from the warm area 6 to the cold area 5 to the in between limit lying webs 10.

FIG. 2 shows how the carrier 1 shown in FIG. 1 fits into a hollow chamber profile 11 can be inserted. The carrier 1 thus serves as reinforcement the plastic hollow chamber profile 11 and for this purpose the carrier 1 through the side walls 12 of the cavity formed in the profile and through Bars 13 and 14 held. The carrier 1 is also in the installed state between a cold area 5 and a warm area 6 such that the Carrier parts 2 and 3 bridging web 4 as reduced in cross section Heat transfer area works.

In the present case, the carrier 1 was inserted into the hollow chamber profile 11 in this way used that the support head 15 faces the tub area 6 and the feet 16 face the cold area 5. However, the carrier 1 can also inserted into the plastic hollow chamber profile rotated by 180 degrees are and also fulfills the task of heat transfer in this position compared to conventional plastic reinforcement profiles.

FIG. 3 shows a carrier 20 which is between two hollow chamber profiles can be used as a coupling. For this purpose, the carrier 20 points on both sides Crosspieces 21, 22, 23, 24 which interact with hollow plastic profiles. Between these webs 21 and 22 or 23 and 24 is one Screw channel 25 or 26 arranged, screwed into the screws or Profiles can be inserted. The webs 21 to 24 and the Screw channels 25 and 26 forming profile walls increase stability of the carrier 20 in opposite areas and in between is a Web 27 arranged in which the neutral fiber 28 of the carrier 20 is located. in the In the area of the neutral fiber 28, elongated holes 29 are made in the web 27, to reduce the heat-conducting cross-section. They are also parallel to the elongated holes 29 offset further elongated holes 30 and 31 in the web 27 provided to further reduce the heat transfer.

The construction of a facade element using two hollow chamber profiles 32, 33 and an intermediate coupling carrier 20 is schematic in Figure 4 shown. Here are U-profiles 34, 35 in the hollow chamber profiles 32, 33 arranged to increase the stability of the hollow chamber profiles. to Reduction of the heat transfer are offset at the base of the U-profiles 34, 35 slotted holes 36, 37, 38, 39 arranged to each other are provided. Between the hollow chamber profiles 32 and 33 is the carrier 20, the the webs 21 to 24 in recesses 40 within the hollow chamber profiles 32 or 33 engages.

The elongated holes 36 to 39 in the U-profiles and 29 in the coupling profile thus for a reduction in heat transfer from a cold area 5 to a warm area 6 without the stability of the supports 34, 35, 20 significantly affect.

Examples of the U-shaped supports used in FIG. 4 are in the figures 5 and 6. These beams show that there are several elongated holes can be arranged side by side and offset from each other to the Restrict heat transfer between a cold side and a warm side.

Figures 7 and 8 represent a way of making breakthroughs or the heat transfer reducing areas. As from the Figure 8 is clearly visible, this is only a cut 41 in the carrier introduced and then those adjoining the cut 41 Carrier areas 42, 43 pressed in, so that the heat transfer surface is reduced becomes.

Various possibilities are shown in FIGS. 9 to 14, as in FIG A carrier areas can be provided in which the heat transfer is disabled. In all of these illustrated embodiments cuts are made in the beam and the area in between deformed.

Figures 15 to 17 show examples in which the thickness of the carrier plate is reduced by incisions or constrictions. This too the heat transfer area is reduced.

Figures 18 to 20 show options such as recesses or deformations can be provided on the carrier. There are options for variation in the type of arrangement of the deformations or breakthroughs and their shape. The examples shown triangle, circle and Square and the arrangement of one or more side by side Lines show that there are a variety of ways to get one to produce carriers according to the invention.

FIG. 21 shows different carrier formats and the position at which in such carrier formats, preferably the heat-conducting cross section is reduced. This position is identified by reference numerals 50 to 57.

The figure shows further possibilities for the formation of carrier profiles 22, in which the areas of reduced cross-section with the reference numerals 60 to 80 are marked.

There are also different types of attachment for the coupling carrier profiles of the reduced-area areas. This is shown in the figures 23 to 26 embodiments of one, two and three row rows of holes shown.

Different embodiments for the production of reinforcement profiles, which can be used in plastic hollow chamber profiles are shown in FIGS. 27 to 47 shown. Here, the frame profile parts with inserted Reinforcement profile shown. However, the wing profile parts are also corresponding essentially similar reinforcement profiles can be used. This is shown by way of example on the embodiment shown in FIG. 40.

Figures 27 to 31 show simple profiles that are in the form of a U, a C or a rectangle are bent and onto the cavity of the hollow profile are coordinated. These carrier profiles have approximately in the area of neutral fiber a cross-section reduction 81 and with a screw 82 the carrier profile parts 83 are held on the frame profile part 84. ribs and webs 85 to 89 allow the carrier 83 in the hollow chamber profile 84 hold. However, these ribs can also be used advantageously are used between the inner wall 90 of the hollow chamber profile part 84 and the carrier 91 to provide a distance. This distance can - As shown in Figure 31 - be used as an isolating airspace, the formed between the carrier 92 and the inner wall of the profile part 84 is. For this purpose, the U-shaped carrier part 92 is made in this way by means of webs 85 to 89 held that between the support part 95 facing the cold region and the inner wall 93 of the hollow chamber profile 94 an insulation space 96 is trained. A corresponding isolation space 97 is on the opposite Side between the support part facing the warm area 98 99 and the inner wall 93 of the hollow section 84.

Figures 32 to 37 show that the carrier parts made of cold-formed metal sheets can be produced. It is possible to use the metal sheets several times on top of each other to make the carrier static. run more stable. The carrier thus preferably has outside the neutral fiber a larger cross-section than in that between the inner and outer support part 100 or 101 lying heat-conducting cross-section 102. This in Cross-section reduced area can also have holes or Material deformations can be reduced even further. This is shown in FIG. 32 a bore 103 indicated.

The other Figures 33 to 37 show that different profile shapes can be reinforced by multilayer training of the support part and this automatically creates the intermediate heat-conducting cross-section is reduced.

FIGS. 38 to 47 show that this also reduces the heat transfer can be that between a first support member 110 and a A second part 111 of a frame spar 112 is arranged in the second carrier part 120 can be. This part 111 is designed as a T-shaped web and separates the carrier parts 110 and 120 from each other and takes over at the same time Holding the carrier parts within the hollow chamber 113 of the hollow chamber profile 112. To move the carrier parts 110 and 120 in the longitudinal direction of the hollow chamber profile 112, screws 114 and 115 are to be avoided provided, which extends through the hollow chamber profile 112 and a respective support part 110 or 120 extend.

FIGS. 39 and 40 show exemplary embodiments corresponding to FIG. 38, in which the carrier parts are reinforced.

The interaction of a frame spar 121 with the spar 122 one Window sash is shown in Figure 41. It can be seen here that the Example of a frame spar shown support parts in the casement can be used. In the embodiment shown, the carrier parts 123 and 124 or 125 and 126 through L-shaped brackets 127, 128 and 129, 130 held.

Further embodiments of carrier parts and holders are the figures 42 to 47 in which webs or L-shaped brackets serve on the hollow chamber profile, single-layer or multi-layer carrier parts in To keep the cavity of a hollow chamber profile spaced apart.

The component 140 shown in FIG. 48 has an essentially U-shaped one Carrier 141, whose legs 142, 143 are placed twice in areas are to increase stability. The legs 142 and 143 form here Case the outer support part and the inner support part, and the the base area in between forms a reduced cross-section Carrier part 144. The reduction in cross section is as in FIGS 14 shown, achieved by a special deformation of the carrier.

The U-shaped cross-sectional area of the carrier forms a limited cavity, in which an insulation body 145 is arranged. Size and shape of the Insulation bodies are matched to the U-shaped carrier in such a way that the Insulation body can be pressed into the carrier and then by the legs 142 and 143 is held against falling out.

FIG. 49 shows that by repeatedly bending a metal sheet, a stable support can be achieved. The embodiment shown relates to a substantially L-shaped carrier 150, which in addition to another L-shaped bracket 151 placed in a frame spar (not shown) can be used. The insulation body 152 and 153 are by the Sides of the L-shaped support 150 or 151 and short holding legs 154 or 155 held.

This makes it possible to support parts such as those shown in FIGS 49 are described, can be combined as required to ensure sufficient frame stability to achieve and at the same time hinder the heat transfer.

The shape and the number of layers allow great variability when dimensioning the beams.

The supports described can be used without an insulating body. However, a further increase in insulation can be achieved by using the insulation body be achieved. The insulation bodies are simply in inserted the carrier profile and held there non-positively. Subsequently can combine the carrier and insulation body into a plastic hollow body profile to be plugged in there the stability and insulation properties to improve.
