Definitions
- the present invention relates in general to metal construction profiles intended for constructing a skeleton for a wall construction, wherein each profile has a substantially U-shaped or C-shaped cross-section, with two substantially parallel side walls and a bottom directed substantially perpendicular to those side walls.
- a skeleton for a wall construction can be built, which wall construction can act as separation wall between two rooms, or as isolating double wall for an outer wall.
- the wall construction also has the function of mutually separating two rooms. In that case, it is of importance that the separation wall has good sound-isolating properties.
- the thermal insulation properties are of importance.
- a skeleton is built by fixing a U-shaped profile to the ground, wherein the bottom of this profile is directed to the floor and the two side walls of this profile are directed upwards, and by also fixing a U-shaped profile to the ceiling, wherein the bottom of this profile is directed towards the ceiling and wherein the side walls of this profile are directed downwards.
- the side walls of the profile fixed to the ceiling are in one plane with the corresponding side walls of the profile fixed to the ground.
- C-shaped profiles (uprights) are placed in the U-shaped profiles, at regular mutual distance from each other.
- two subsequent C-shaped uprights, together with the portions of the bottom profile and the ceiling profile extending between them, define a rectangular accommodation space in which an insulation mat is arranged.
- wall panels are connected to the side walls of the C-shaped uprights and of the U-shaped horizontal profiles. These wall panels can, for instance, be made of plasterboard.
- the skeleton stands at a short distance from an outer wall, and the wall panels are only arranged to one side of the skeleton formed by the profiles; at the opposite side of the skeleton, a cavity space remains between the profiles and the corresponding outer wall.
- wall panels are connected to both opposite side walls of the profiles.
- Such a wall construction has primarily been designed because of its insulating properties, i.e. thermal insulation and sound insulation, wherein, in the case of a separation wall between two rooms within a building, the insulation of sound is the most important.
- the known per se insulation mats offer a good thermal insulation and sound insulation, while the wall panels to be arranged basically have a thermal insulation function.
- a problem of conventional profiles is that the profile bottom forms a bridge which is thermally conductive, and which also conducts sound well. As a consequence, it can happen that the wall as a whole does not meet legal standards, while the insulation mats and the wall panels do meet those standards.
- An important aim of the present invention is to solve the problems mentioned.
- the profile comprises two profile halves, wherein each profile half comprises a profile side wall and a profile bottom part, wherein the two profile bottom parts of the two profile halves at least partially overlap each other, wherein the overlapping bottom parts are connected to each other by an insulating connection piece.
- a metal profile according to the preamble of claims 1 is known from US patent 5.860.265 , which is built from two profile halves with overlapping bottom parts, wherein a strip of thermally insulating material is arranged between the bottom parts.
- the thermally insulating material does not have the function of mutually connecting together the two bottom halves lying on each other.
- a profile according to the invention has the characterizing features of claim 1.
- the insulating strip is connected to both bottom parts overlapping each other by means of surface bonding, such that the insulating strip effects the mutual connection of those two bottom halves without additional fastening means such as rivets or the like being necessary for this.
- additional fastening means such as rivets or the like being necessary for this.
- FIG. 1 schematically shows a cross-section of a construction profile 1 according to the present invention.
- the profile 1 comprises a bottom 3 and two side walls 11 and 21.
- the bottom 3 has a central part which is raised with respect to edge parts of this bottom.
- the profile 1 comprises two profile halves 10 and 20, which are connected to each other by an insulating strip 2.
- the first profile half 10 has a first side wall 11 and a first bottom section 14, which mutually make an angle of substantially 90°.
- the bottom section 14 comprises three bottom section parts 15, 16, 17, wherein the first bottom section part 15 connects to the side wall 11, wherein a second bottom section part 16 connects to the first bottom section part 15 and makes an angle with it, and wherein the third bottom section part 17 connects to the second bottom section part 16 and makes an angle with it, all such that the three bottom section parts 15, 16, 17 define a generally S-shaped contour wherein the third bottom section part 17 is directed substantially parallel to the first bottom section part 15.
- the mutual distance D between the first bottom section part 15 and the third bottom section part 17, measured perpendicularly to the surface of those bottom section parts 15 and 17, is determined by the size of the said angles and by the length of the intermediate second bottom section part 16, as will be clear to a person skilled in the art.
- the bottom section 14 is an entirely flat bottom section, such that the three bottom section parts 15, 16, 17 are aligned with each other.
- the embodiment as shown is preferred because the S-shaped contour offers an increased strength.
- FIG 1 some detail variations are illustrated for the end of the first side wall 11 directed away from the bottom section 14.
- a first variation illustrated at A, the end of the side wall 11 is simply straight.
- the construction profile 1 is also indicated as a U-profile 1U.
- the first side wall 11 is provided with an end strip 12 which is folded inwards with respect to the side wall 11 over an angle of approximately 90°.
- the construction profile 1 is also indicated as a C-profile 1C.
- An advantage of the C-profile with respect to the U-profile is the increased stiffness of the side wall 11.
- a variation of the U-profile of detail A is shown at C, in which the first side wall 11 is provided with an end strip 12, which is folded inwards over an angle of approximately 180°.
- a variation of the C-profile of detail B is shown at D by way of example, in which the first side wall 11 is provided with a first end strip 12 which is folded inwards with respect to the first side wall 11 over an angle of approximately 90°, and a second end strip 13 which is folded inwards with respect to the first end strip 12 over an angle of approximately 180°, back to the first side wall 11.
- the second profile half 20 has a second side wall 21 and a second bottom section 24 which comprises three bottom section parts 25, 26, 27, which bottom section parts together define a substantially S-shaped contour.
- the two profile halves 10 and 20 are arranged next to eachother, wherein their bottom sections 14 and 24 are directed towards each other, and wherein the third bottom section part 17 of the first bottom section 14 has an end segment 18 which overlaps an end segment 28 of the third bottom section part 27 of the second bottom section 24.
- the width of the overlap is indicated at L in figure 1 .
- the mutually overlapping bottom segments 18 and 28 are connected to each other by the strip 12 between them.
- the first bottom section part 15 of the first bottom section 14 is aligned with the first bottom section part 25 of the second bottom section 24. This implies that the vertical distance between the third bottom section part 27 of the second bottom section 24 and the first bottom section part 25 of the second bottom section 24, indicated in figure 1 at d, is smaller than the corresponding distance D between the third bottom section part 17 of the first bottom section 14 and the first bottom section part 15 of the first bottom section 14.
- the two bottom sections 14 and 24 together i.e. the six bottom section parts 15, 16, 17, 27, 26, 25 together, form the bottom 3 of the construction profile 1.
- the side walls 11 and 21 mutually are substantially parallel.
- the strip 2 is made of a material which has good sound-insulating properties and which has good thermal insulating properties.
- a preferred material which has appeared suitable is a durable and weather-resistant 40° Shore EPDM-rubber.
- the thickness of the strip 2 can for instance be chosen in the range of 1 to 5 mm, but is preferably chosen in the range of 2 to 4 mm.
- the width of the strip 2, which preferably corresponds to the overlap L, can for instance be chosen in the range of 10 to 50 mm or larger, but has in a preferred embodiment a width of about 15-25 mm, wherein a width of about 20 mm is most preferred.
- the total width of the construction profile 1, i.e. the distance between the two side walls 11 and 21, can be chosen as desired. Although in that case the overlap L and the width of the strip 2 can vary also, the width of the strip 2 is preferably always set at the same value. Varying the total width is then preferably done by varying the width of the third bottom section parts 17 and 27, while keeping constant the width of the remaining bottom section parts and of the end segments 18 and 28.
- Figures 2 and 2A schematically show a longitudinal section of the two overlapping bottom segments 18, 28 and the strip 2 in between.
- the strip 2 can be a contiguous strip, as illustrated in figure 2A , but in the variation of embodiment indicated in figure 2 , the strip 2 is an interrupted strip, such that separate strip sections 2A and 2B are visible in figure 2 , with gaps 4. In the region of these gaps 4, the bottom sections 14 and 24 are thus not connected to each other.
- the contiguous strip illustrated in figure 2A is preferred.
- FIG. 3 is a perspective view which illustrates the use of the construction profile 1 according to the present invention in an application situation.
- a skeleton 30 of a double wall 31 for an outer wall 32 has been built with the construction profile 1.
- a U-shaped construction profile 1U is arranged on a floor; the same applies to the ceiling, but this is not shown.
- C-shaped construction profiles 1C are arranged, substantially perpendicular to the lying U-shaped floor profile 1U and with a regular mutual distance.
- Insulation mats 35 are arranged between the C-shaped uprights 1C.
- Wall panels 36 for instance plasterboards, are arranged to the U-shaped beams 1U and the C-shaped uprights 1C.
- the skeleton 30 formed by the profiles 1U, 1C is capable of fully supporting the double wall 31, and can stand free from the outer wall 32, such that a cavity is present between the outer wall 32 and the double wall 31.
- such a double wall 31 has an insulating effect which is determined on the one hand by the insulating mats 35 and the wall panels 36, and on the other hand by the construction profiles 1.
- the bottom of the profile forms a thermal bridge between the side walls of the profile, and also there is a good sound transfer.
- the profile 1 proposed by the present invention such a heat transfer and sound transfer is counter acted because the metal bottom sections 14 and 24 do not touch each other. Either they are attached to each other by the strip 2 with heat-insulating and sound-insulating properties or they are even entirely free from each other (interspaces 4).
- FIG 4A schematically shows a top view of a part of a strong wall 40 constructed using conventional profiles 41.
- a strong wall 40 is provided with finishing plates 46A, 46B at both sides.
- thermal insulation is no primary requirement, but sound insulation is very important.
- so-called double skeleton framework is used, in fact consisting of two half-walls placed next to each other, wherein the one skeleton supports the one wall and wherein the other skeleton supports the other wall.
- the uprights 44A, 44B of the two different skeletons are placed at a mutual distance A to each other. It is true that a good insulation is achieved by this, but building such a wall requires relatively much labor and material and thus is relatively expensive.
- environmental problems are associated with this: since the profiles are usually manufactured of galvanized iron, the use of a double skeleton implies a double environmental burden regarding zinc.
- Figure 4B is a comparable view of a strong wall constructed with profiles 1 as proposed by the present invention. With those profiles, it is possible to build a wall 27 in single skeleton framework offering the same or improved insulating properties. It can be recognized in figure 4B that a single upright 48 (profile 1C) supports both the one finishing plate 46A as the opposite finishing plate 46B. The total thickness of the wall 40 can thus be reduced, and building can be performed simpler and quicker.
- a preferred method for manufacturing a profile according to the present invention will be explained, referring to figures 5 and further.
- As basic material use is made of galvanized iron strips 41, which are provided on a roll 50 in a desired width and with large length.
- the profiles proposed by the present invention can be manufactured from another metal, galvanized iron strips are preferred.
- the metal strip 51 is wound off the supply roll 50, and at least one edge part 52 of a surface 53 of this strip 51 is subjected to pre-processing actions.
- pre-processing actions comprise consecutively:
- an adhesive primer 54 is applied to the roughened and degreased edge portion 52.
- a commercially available adhesive primer can be used here; an adhesive primer which has appeared suitable is, for instance, the adhesive primer which is available from the company HENKEL under the name CHEMOSEAL.
- a strip 51 provided with adhesive primer 54 in this way is also indicated as preprocessed strip 61 in the following.
- a preprocessed strip 51 is considered a first intermediate product in the context of the present invention. If desired, this intermediate product can, preferably after the adhesive primer 54 has dried, be wound again on a supply roll 59, and then can be kept in storage for some time. Further processing steps can then be performed on the basis of a preprocessed strip 61 wound on a supply roll 59, as will be discussed in the following by way of example. However, it is very well possible to perform the following processing steps directly following the preprocessing actions discussed above.
- two of such preprocessed strips 61 are connected to each other. It is noted that the two preprocessed strips 61 to be attached to each other can be mutually identical strips, such that no separate supplies of left and right strips are necessary. Further it is noted that, if the following process step is performed directly following the preprocessing actions discussed above, use can be made of two preprocessing stations for preprocessing two strips 51 in parallel.
- a first preprocessed strip 61 1 is wound off from a first supply roll 59 1 , the strip 61 1 substantially being directed horizontally and the surface 53 1 provided with adhesive primer being on top.
- An EPDM rubber 2 is applied to the surface portion 52 provided with adhesive primer 54.
- the EPDM rubber 2 is injected as a viscous mass by means of one or more nozzles 62, which can be stationary.
- the EPDM rubber can leave the nozzle 62 as a continuous flow, such that a continuous ridge or bead of EPDM rubber 2 is thus applied to the strip 61 1 , as shown, but the rubber can also leave the nozzle 62 with intervals and thus be applied as a series of consecutive pads.
- the EPDM rubber can have a temperature of approximately 20-25 °C (room temperature), but if desired it is also possible to apply the rubber at a slightly raised temperature of approximately 40-60 °C.
- a second preprocessed strip 61 2 is wound off from a second supply roll 59 2 , which is arranged in mirror image and slightly displaced with respect to the first supply roll 59 1 , wherein the second preprocessed strip 61 2 is directed substantially parallel to the first preprocessed strip 61 1 and the surface 53 2 provided with adhesive primer is at the underside.
- the two preprocessed strips 61 1 and 61 2 are displaced with respect to each other in such a way that the respective edge parts 52 1 , 52 2 provided with adhesive primer are aligned with each other, wherein the surfaces 53 1 , 53 2 provided with adhesive primer are facing each other.
- the two supply rolls 59 1 and 59 2 can be arranged directly above each other (albeit axially displaced with respect to each other), as shown.
- the two strips 61 1 , 61 2 with the EPDM rubber 2 in between are brought to a raised temperature and pressed against each other.
- the temperature achieved here is for instance approximately 180 °C.
- the composition of EPDM rubber can vary in practice, and a suitable temperature can vary depending on the exact composition.
- composite strip 71 is considered a second intermediate product in the context of the present invention.
- This composite strip 71 can directly be further processed for forming a construction profile, but it can also, as intermediate product, be wound on a supply roll 69 for later processing. In this case, it is preferred to avoid small radii of curvature, such that the winding roll for the composite strip preferably has a relatively large diameter of for instance approximately 80 cm.
- the strips 61 1 , 61 2 are guided through a series of subsequent rollers 63, as shown in figure 6A , which press the strips 61 1 , 61 2 against each other at the correct mutual distance, which mutual distance defines the final thickness of the EPDM strip to be formed.
- the series of rollers forms a roller train, wherein a first set of rollers in the roller train are also adapted to supply heat to the strips 61 1 , 61 2 and the rubber 2 in order to let this reach a temperature of about 180 °C, while a second set of rollers in the roller train are also adapted to withdraw heat from the strips 61 1 , 61 2 and the rubber 2 in order to achieve a certain desired cooling of the composite strip.
- it is assured that the temperature of the composite strip has dropped to approximately 40-60 °C.
- the composite strip 71 is folded by means of rollers to a gutter shape in a continuous process.
- Such a folding process by means of rollers is known per se and is, therefore, not described extensively.
- a raised central part 5 is formed in the bottom part 3 by two rollers 81, 82 ( figure 8 ) cooperating with each other, wherein the one roller 81 is provided with a recess 83 and the other roller 82 is provided with a corresponding elevation 84, wherein the elevation 84 of this second roller 82 presses the central part of the material of the gutter into the recess 83 of the first roller 81.
- the recess 83 of the first roller 81 has a first recess section 83A intended to support a part of the third bottom section part 27 of the second bottom section 24 to be formed, and a second recess section 83B intended to support the entire third bottom section part 17 of the first bottom section 14 to be formed, including the end segment 18 thereof.
- the elevation 84 of the second roller 82 has a first elevation section 84A intended to press away a part of the third bottom section part 17 of the first bottom section 14 to be formed, and a second elevation section 84B intended to press away the entire third bottom section part 27 of the second bottom section 24 to be formed.
- Each roller can be comprised of two segments, as shown.
- An important advantage of the composite strip 71 is that the rubber connection material 2 is confined between two metal parts 61 1 , 61 2 , whereby it is possible to perform the shaping of the raised central bottom part 5 by means of rollers 81, 82.
- Such shaping step by means of rollers is not or hardly possible if a rubber coupling strip would have an H-profile, or if the two bottom halves are connected to each other by means of rivets.
- ends of the composite strip 71 are folded over approximately 90° by means of folding rollers (not shown) in order to form the folded end edges 12 of a C-profile (see figure 7B ); this step can be omitted if a U-profile is to be formed.
- folding rollers not shown
- side wall parts 11 and 21 are folded over substantially 90° with respect to the bottom part 3 (see figure 7C ).
- the present invention provides a variation of embodiment which provides additional insulation against contact sound, which variation of embodiment is illustrated in figure 9 .
- the first bottom section part 15 of the first bottom section 14 is at a higher level than the first bottom section part 25 of the second bottom section 24, such that, in the case of placing on a floor, the first bottom section part 15 of the first bottom section 14 remains free from this floor.
- the first bottom section 14 is then supported by a support strip 90 of a suitable sound-damping material, such as for instance a neoprene-like material which is to be placed separately, and the first bottom section 14 is pressed downwards onto this support strip 90 by its own weight and by the second bottom section 24, which is secured to the floor by means of for instance screws (not shown).
- This support strip 90 can be placed under the first bottom section part 15 of the first bottom section 14 or, as shown, under the third bottom section part 17 of the first bottom section 14.
- This support strip 90 can have a thickness of about 3 mm.
- the third bottom section part 17 of the first bottom section 14, under which this support strip 90 is placed is above the third bottom section part 27 of the second bottom section 24. Then, when the third bottom section part 17 of the first bottom section 14 is pressed by the third bottom section part 27 of the second bottom section 24, the rubber strip 2 is put under strain of tension.
- the support strip 90 is placed under that bottom section part which is the lowest of the two bottom section parts, i.e. the third bottom section part 27 of the second bottom section 24 in figure 9 ; in that case, the rubber strip 2 is put under pressure when the third bottom section part 27 of the second bottom section 24 is pressed by the third bottom section part 17 of the first bottom section 14.

Abstract
Description
- The present invention relates in general to metal construction profiles intended for constructing a skeleton for a wall construction, wherein each profile has a substantially U-shaped or C-shaped cross-section, with two substantially parallel side walls and a bottom directed substantially perpendicular to those side walls.
- With such profiles, a skeleton for a wall construction can be built, which wall construction can act as separation wall between two rooms, or as isolating double wall for an outer wall. In the case of an inner wall, the wall construction also has the function of mutually separating two rooms. In that case, it is of importance that the separation wall has good sound-isolating properties. In the case of a double wall for an outer wall, especially the thermal insulation properties are of importance.
- A skeleton is built by fixing a U-shaped profile to the ground, wherein the bottom of this profile is directed to the floor and the two side walls of this profile are directed upwards, and by also fixing a U-shaped profile to the ceiling, wherein the bottom of this profile is directed towards the ceiling and wherein the side walls of this profile are directed downwards. The side walls of the profile fixed to the ceiling are in one plane with the corresponding side walls of the profile fixed to the ground. Then, C-shaped profiles (uprights) are placed in the U-shaped profiles, at regular mutual distance from each other. In this case, two subsequent C-shaped uprights, together with the portions of the bottom profile and the ceiling profile extending between them, define a rectangular accommodation space in which an insulation mat is arranged. Finally, wall panels are connected to the side walls of the C-shaped uprights and of the U-shaped horizontal profiles. These wall panels can, for instance, be made of plasterboard.
- In the case of a double wall, the skeleton stands at a short distance from an outer wall, and the wall panels are only arranged to one side of the skeleton formed by the profiles; at the opposite side of the skeleton, a cavity space remains between the profiles and the corresponding outer wall. In the case of a separation wall between two rooms within a building, wall panels are connected to both opposite side walls of the profiles.
- Such a wall construction has primarily been designed because of its insulating properties, i.e. thermal insulation and sound insulation, wherein, in the case of a separation wall between two rooms within a building, the insulation of sound is the most important. The known per se insulation mats offer a good thermal insulation and sound insulation, while the wall panels to be arranged basically have a thermal insulation function. However, a problem of conventional profiles is that the profile bottom forms a bridge which is thermally conductive, and which also conducts sound well. As a consequence, it can happen that the wall as a whole does not meet legal standards, while the insulation mats and the wall panels do meet those standards.
- Especially in the case of application as double wall for a cold outer wall it can happen that the side wall of the profile directed away from the outer wall becomes cold to such extent that condensation is formed there, which can lead to color differences on the wall panels in the region of the profiles.
- An important aim of the present invention is to solve the problems mentioned.
- According to an important aspect of the present invention, the profile comprises two profile halves, wherein each profile half comprises a profile side wall and a profile bottom part, wherein the two profile bottom parts of the two profile halves at least partially overlap each other, wherein the overlapping bottom parts are connected to each other by an insulating connection piece.
- It is noted that a metal profile according to the preamble of
claims 1 is known fromUS patent 5.860.265 , which is built from two profile halves with overlapping bottom parts, wherein a strip of thermally insulating material is arranged between the bottom parts. In this known construction, the thermally insulating material does not have the function of mutually connecting together the two bottom halves lying on each other. In order to connect the construction parts to each other, it is necessary in this known construction that mutually aligned holes are formed in the two bottom parts lying over each other and in the insulation strip lying there between, and that thermally insulated rivets are arranged in those through openings. This makes the manufacturing of such a profile very complicated and expensive. Further, it is true that it will be possible in this way to arrange a thermal interruption between the two opposite side walls of the profile, but because of the stiff connection between the two bottom parts lying on each other, caused by the rivets, only little or no sound-insulating effect is achieved. - In contrast, a profile according to the invention has the characterizing features of
claim 1. In the case of the profile proposed by the present invention, the insulating strip is connected to both bottom parts overlapping each other by means of surface bonding, such that the insulating strip effects the mutual connection of those two bottom halves without additional fastening means such as rivets or the like being necessary for this. Not only can such a profile be manufactured more easily and cheaper than a profile which is provided with rivets, but, moreover, better thermal insulation properties and better sound-insulating properties can be combined with each other by such a construction as proposed by the present invention. - These and other aspects, features and advantages of the present invention will be clarified in more detail by the following description of preferred embodiments of construction profiles according to the present invention with reference to the drawings, in which same reference numerals indicate same or similar parts, and in which:

Figure 1 schematically shows a cross-section of aconstruction profile 1 according to the present invention. Theprofile 1 comprises abottom 3 and twoside walls bottom 3 has a central part which is raised with respect to edge parts of this bottom. Theprofile 1 comprises twoprofile halves insulating strip 2. Thefirst profile half 10 has afirst side wall 11 and afirst bottom section 14, which mutually make an angle of substantially 90°. Thebottom section 14 comprises threebottom section parts bottom section part 15 connects to theside wall 11, wherein a secondbottom section part 16 connects to the firstbottom section part 15 and makes an angle with it, and wherein the thirdbottom section part 17 connects to the secondbottom section part 16 and makes an angle with it, all such that the threebottom section parts bottom section part 17 is directed substantially parallel to the firstbottom section part 15. The mutual distance D between the firstbottom section part 15 and the thirdbottom section part 17, measured perpendicularly to the surface of thosebottom section parts bottom section part 16, as will be clear to a person skilled in the art. - Within the context of the present invention, it is possible that the
bottom section 14 is an entirely flat bottom section, such that the threebottom section parts - In
figure 1 , some detail variations are illustrated for the end of thefirst side wall 11 directed away from thebottom section 14. In a first variation, illustrated at A, the end of theside wall 11 is simply straight. In this case, theconstruction profile 1 is also indicated as a U-profile 1U. - In a second variation, illustrated at B, the
first side wall 11 is provided with anend strip 12 which is folded inwards with respect to theside wall 11 over an angle of approximately 90°. In this case, theconstruction profile 1 is also indicated as a C-profile 1C. An advantage of the C-profile with respect to the U-profile is the increased stiffness of theside wall 11. - Within the context of the present invention, however, more variations are possible. By way of example, a variation of the U-profile of detail A is shown at C, in which the
first side wall 11 is provided with anend strip 12, which is folded inwards over an angle of approximately 180°. Further, a variation of the C-profile of detail B is shown at D by way of example, in which thefirst side wall 11 is provided with afirst end strip 12 which is folded inwards with respect to thefirst side wall 11 over an angle of approximately 90°, and asecond end strip 13 which is folded inwards with respect to thefirst end strip 12 over an angle of approximately 180°, back to thefirst side wall 11. - In a manner similar as discussed above regarding the
first profile half 10, thesecond profile half 20 has asecond side wall 21 and asecond bottom section 24 which comprises threebottom section parts second side wall 21, the same applies as that what has been mentioned in the above with respect to the free end of thefirst side wall 11, but this is not illustrated separately infigure 1 . - The two
profile halves bottom sections bottom section part 17 of thefirst bottom section 14 has anend segment 18 which overlaps anend segment 28 of the thirdbottom section part 27 of thesecond bottom section 24. The width of the overlap is indicated at L infigure 1 . The mutually overlappingbottom segments strip 12 between them. - In the embodiment schematically shown in
figure 1 , the firstbottom section part 15 of thefirst bottom section 14 is aligned with the firstbottom section part 25 of thesecond bottom section 24. This implies that the vertical distance between the thirdbottom section part 27 of thesecond bottom section 24 and the firstbottom section part 25 of thesecond bottom section 24, indicated infigure 1 at d, is smaller than the corresponding distance D between the thirdbottom section part 17 of thefirst bottom section 14 and the firstbottom section part 15 of thefirst bottom section 14. - The two
bottom sections bottom section parts bottom 3 of theconstruction profile 1. Theside walls - The
strip 2 is made of a material which has good sound-insulating properties and which has good thermal insulating properties. A preferred material which has appeared suitable is a durable and weather-resistant 40° Shore EPDM-rubber. The thickness of thestrip 2 can for instance be chosen in the range of 1 to 5 mm, but is preferably chosen in the range of 2 to 4 mm. The width of thestrip 2, which preferably corresponds to the overlap L, can for instance be chosen in the range of 10 to 50 mm or larger, but has in a preferred embodiment a width of about 15-25 mm, wherein a width of about 20 mm is most preferred. - The total width of the
construction profile 1, i.e. the distance between the twoside walls strip 2 can vary also, the width of thestrip 2 is preferably always set at the same value. Varying the total width is then preferably done by varying the width of the thirdbottom section parts end segments -
Figures 2 and 2A schematically show a longitudinal section of the two overlappingbottom segments strip 2 in between. Thestrip 2 can be a contiguous strip, as illustrated infigure 2A , but in the variation of embodiment indicated infigure 2 , thestrip 2 is an interrupted strip, such thatseparate strip sections figure 2 , with gaps 4. In the region of these gaps 4, thebottom sections figure 2A is preferred. -
Figure 3 is a perspective view which illustrates the use of theconstruction profile 1 according to the present invention in an application situation. In the application situation shown infigure 3 , a skeleton 30 of adouble wall 31 for anouter wall 32 has been built with theconstruction profile 1. A U-shaped construction profile 1U is arranged on a floor; the same applies to the ceiling, but this is not shown. In the U-shaped construction profile 1U lying on the floor, C-shapedconstruction profiles 1C are arranged, substantially perpendicular to the lying U-shaped floor profile 1U and with a regular mutual distance.Insulation mats 35 are arranged between the C-shapeduprights 1C.Wall panels 36, for instance plasterboards, are arranged to the U-shaped beams 1U and the C-shapeduprights 1C. The skeleton 30 formed by theprofiles 1U, 1C is capable of fully supporting thedouble wall 31, and can stand free from theouter wall 32, such that a cavity is present between theouter wall 32 and thedouble wall 31. - Regarding heat and sound, such a
double wall 31 has an insulating effect which is determined on the one hand by the insulatingmats 35 and thewall panels 36, and on the other hand by the construction profiles 1. When using conventional metal profiles, which are made as a whole, the bottom of the profile forms a thermal bridge between the side walls of the profile, and also there is a good sound transfer. In the case of theprofile 1 proposed by the present invention, such a heat transfer and sound transfer is counter acted because themetal bottom sections strip 2 with heat-insulating and sound-insulating properties or they are even entirely free from each other (interspaces 4). -
Figure 4A schematically shows a top view of a part of astrong wall 40 constructed using conventional profiles 41. Such astrong wall 40 is provided with finishingplates uprights -
Figure 4B is a comparable view of a strong wall constructed withprofiles 1 as proposed by the present invention. With those profiles, it is possible to build awall 27 in single skeleton framework offering the same or improved insulating properties. It can be recognized infigure 4B that a single upright 48 (profile 1C) supports both the onefinishing plate 46A as theopposite finishing plate 46B. The total thickness of thewall 40 can thus be reduced, and building can be performed simpler and quicker. - Now, a preferred method for manufacturing a profile according to the present invention will be explained, referring to
figures 5 and further. As basic material, use is made of galvanized iron strips 41, which are provided on aroll 50 in a desired width and with large length. Although the profiles proposed by the present invention can be manufactured from another metal, galvanized iron strips are preferred. - In a first process step, the
metal strip 51 is wound off thesupply roll 50, and at least oneedge part 52 of asurface 53 of thisstrip 51 is subjected to pre-processing actions. These pre-processing actions comprise consecutively: - a grinding process for roughening this
edge portion 52, indicated at 52A infigure 5 ; - a degreasing process with any suitable grease-solvent, indicated at 52B in
figure 5 . - Subsequently, an
adhesive primer 54 is applied to the roughened and degreasededge portion 52. A commercially available adhesive primer can be used here; an adhesive primer which has appeared suitable is, for instance, the adhesive primer which is available from the company HENKEL under the name CHEMOSEAL. - A
strip 51 provided withadhesive primer 54 in this way is also indicated as preprocessedstrip 61 in the following. Such a preprocessedstrip 51 is considered a first intermediate product in the context of the present invention. If desired, this intermediate product can, preferably after theadhesive primer 54 has dried, be wound again on asupply roll 59, and then can be kept in storage for some time. Further processing steps can then be performed on the basis of a preprocessedstrip 61 wound on asupply roll 59, as will be discussed in the following by way of example. However, it is very well possible to perform the following processing steps directly following the preprocessing actions discussed above. - In a following process step, two of such preprocessed
strips 61 are connected to each other. It is noted that the two preprocessedstrips 61 to be attached to each other can be mutually identical strips, such that no separate supplies of left and right strips are necessary. Further it is noted that, if the following process step is performed directly following the preprocessing actions discussed above, use can be made of two preprocessing stations for preprocessing twostrips 51 in parallel. - As shown in
figure 6A , a first preprocessedstrip 611 is wound off from afirst supply roll 591, thestrip 611 substantially being directed horizontally and thesurface 531 provided with adhesive primer being on top. AnEPDM rubber 2 is applied to thesurface portion 52 provided withadhesive primer 54. Preferably, theEPDM rubber 2 is injected as a viscous mass by means of one ormore nozzles 62, which can be stationary. The EPDM rubber can leave thenozzle 62 as a continuous flow, such that a continuous ridge or bead ofEPDM rubber 2 is thus applied to thestrip 611, as shown, but the rubber can also leave thenozzle 62 with intervals and thus be applied as a series of consecutive pads. - It is noted that the thickness of the rubber ridge is shown exaggeratedly large in
figure 6A . - It is further noted that, during application, the EPDM rubber can have a temperature of approximately 20-25 °C (room temperature), but if desired it is also possible to apply the rubber at a slightly raised temperature of approximately 40-60 °C.
- A second preprocessed
strip 612 is wound off from asecond supply roll 592, which is arranged in mirror image and slightly displaced with respect to thefirst supply roll 591, wherein the second preprocessedstrip 612 is directed substantially parallel to the first preprocessedstrip 611 and thesurface 532 provided with adhesive primer is at the underside. The two preprocessedstrips respective edge parts surfaces - Subsequently, the two
strips EPDM rubber 2 in between are brought to a raised temperature and pressed against each other. The temperature achieved here is for instance approximately 180 °C. As will be clear to a person skilled in the art, the composition of EPDM rubber can vary in practice, and a suitable temperature can vary depending on the exact composition. - Subsequently, the two
strips EPDM rubber 2 are allowed to cool down. After having cooled down sufficiently, therubber 2 has sufficient intrinsic strength and sufficient adhesion with the two strips, such that it can be strained mechanically. The thus-formed combination of the twostrips EPDM rubber 2, which will hereinafter be indicated ascomposite strip 71, is considered a second intermediate product in the context of the present invention. Thiscomposite strip 71 can directly be further processed for forming a construction profile, but it can also, as intermediate product, be wound on a supply roll 69 for later processing. In this case, it is preferred to avoid small radii of curvature, such that the winding roll for the composite strip preferably has a relatively large diameter of for instance approximately 80 cm. - In a preferred continuous process, the
strips subsequent rollers 63, as shown infigure 6A , which press thestrips strips rubber 2 in order to let this reach a temperature of about 180 °C, while a second set of rollers in the roller train are also adapted to withdraw heat from thestrips rubber 2 in order to achieve a certain desired cooling of the composite strip. Preferably, it is assured that the temperature of the composite strip has dropped to approximately 40-60 °C. - In a subsequent stage, the
composite strip 71 is folded by means of rollers to a gutter shape in a continuous process. Such a folding process by means of rollers is known per se and is, therefore, not described extensively. - Preferably, a raised central part 5 (see
figure 7A ) is formed in thebottom part 3 by tworollers 81, 82 (figure 8 ) cooperating with each other, wherein the oneroller 81 is provided with arecess 83 and theother roller 82 is provided with acorresponding elevation 84, wherein theelevation 84 of thissecond roller 82 presses the central part of the material of the gutter into therecess 83 of thefirst roller 81. Therecess 83 of thefirst roller 81 has afirst recess section 83A intended to support a part of the thirdbottom section part 27 of thesecond bottom section 24 to be formed, and asecond recess section 83B intended to support the entire thirdbottom section part 17 of thefirst bottom section 14 to be formed, including theend segment 18 thereof. Theelevation 84 of thesecond roller 82 has afirst elevation section 84A intended to press away a part of the thirdbottom section part 17 of thefirst bottom section 14 to be formed, and asecond elevation section 84B intended to press away the entire thirdbottom section part 27 of thesecond bottom section 24 to be formed. Each roller can be comprised of two segments, as shown. - An important advantage of the
composite strip 71 is that therubber connection material 2 is confined between twometal parts bottom part 5 by means ofrollers - Then, ends of the
composite strip 71 are folded over approximately 90° by means of folding rollers (not shown) in order to form the folded end edges 12 of a C-profile (seefigure 7B ); this step can be omitted if a U-profile is to be formed. By means of a subsequent set of folding rollers,side wall parts figure 7C ). - In the above, it has been described that the first
bottom section parts bottom sections bottom section parts figure 3 ). In that case, it might happen that sound which reaches the one wall, reaches the other wall via the bottom contact. Therefore, the present invention provides a variation of embodiment which provides additional insulation against contact sound, which variation of embodiment is illustrated infigure 9 . In this variation of embodiment, the firstbottom section part 15 of thefirst bottom section 14 is at a higher level than the firstbottom section part 25 of thesecond bottom section 24, such that, in the case of placing on a floor, the firstbottom section part 15 of thefirst bottom section 14 remains free from this floor. Thefirst bottom section 14 is then supported by asupport strip 90 of a suitable sound-damping material, such as for instance a neoprene-like material which is to be placed separately, and thefirst bottom section 14 is pressed downwards onto thissupport strip 90 by its own weight and by thesecond bottom section 24, which is secured to the floor by means of for instance screws (not shown). Thissupport strip 90 can be placed under the firstbottom section part 15 of thefirst bottom section 14 or, as shown, under the thirdbottom section part 17 of thefirst bottom section 14. Thissupport strip 90 can have a thickness of about 3 mm. - In the embodiment illustrated, the third
bottom section part 17 of thefirst bottom section 14, under which thissupport strip 90 is placed, is above the thirdbottom section part 27 of thesecond bottom section 24. Then, when the thirdbottom section part 17 of thefirst bottom section 14 is pressed by the thirdbottom section part 27 of thesecond bottom section 24, therubber strip 2 is put under strain of tension. Preferably, thesupport strip 90 is placed under that bottom section part which is the lowest of the two bottom section parts, i.e. the thirdbottom section part 27 of thesecond bottom section 24 infigure 9 ; in that case, therubber strip 2 is put under pressure when the thirdbottom section part 27 of thesecond bottom section 24 is pressed by the thirdbottom section part 17 of thefirst bottom section 14. - It will be clear to a person skilled in the art that the invention is not limited to the exemplary embodiments discussed above but that several variations and modifications are possible within the protective scope of the invention as defined in the attached claims. For instance, it is possible that the profiles are used for constructing a skeleton of a ceiling.
- In the above, the profile has been described for constructing a skeleton of a separation wall. Separation walls are relatively light-weight walls. However, it is also possible to manufacture the profiles with such a thickness and strength that they can act as building construction parts of a supporting wall.
