Definitions

  • the invention relates to a heat-insulating profile body, in particular for use in door or window frames or the like, consisting of two profile rails, preferably those made of metal, which are connected to one another by two profiled insulating webs made of heat-insulating material, the insulating webs being made from a supporting web and engage undercut grooves of the profiled rails formed in a retaining web.
  • the invention further relates to a method for producing this heat-insulating profile body and a tool for carrying out this method.
  • Such heat-insulating profile bodies are known. With them, the insulating bars serve to rigidly connect the two rails. Various methods are now known with which this connection can be brought about.
  • So z. B. known to dimension the insulating webs so that they can be inserted with all-round play in the undercut grooves of the rails.
  • the insulating webs are then attached in that the cavity which the .insolating webs and the profile rails enclose are filled with a foam which expands on solidification. Due to this expansion, the insulating webs and the profile rails are firmly pressed together in their fitting position. At the points where the profile rails and the insulating webs meet, there is a very strong frictional connection, which prevents mutual displacement.
  • the foam can also serve as an adhesive.
  • the profile bodies produced by this process have good properties, but their manufacture requires high investment costs. Furthermore, in certain cases, such profile bodies cannot be used with regard to the flammability of the foam.
  • the object of the invention is to provide a heat-insulating profile body which can be produced with simple means and which has a very firm and permanent connection between the insulating webs and the profile rails, so that the frictional engagement between the insulating webs and the profile rails is also stable over a long period of time and thus the profile body remains rigid.
  • individual deformations which protrude into the groove and which abut the insulating web, are arranged at a distance from one another on the support webs, optionally also the holding webs of the undercut grooves. If the deformations are more pronounced, they can also penetrate the insulating web. If, as is preferably provided, the supporting web is deformed, the insulating web is pressed against the end face of the holding web of the groove and thus a permanent contact pressure is exerted.
  • the insulating web can be pressed not only against the end face of the above-mentioned retaining web, but also as a fixed system of the insulating web on a further inner surface of the holding web. This is done, for example, in such a way that when producing the individual deformations, the profiled rails are pressed apart or pulled so that the legs of the insulating webs are pressed firmly against those stop surfaces of the holding webs which are perpendicular to their end faces.
  • the insulating web is provided with longitudinal grooves on its surface facing the holding web.
  • the grooves of the insulating web prevent displacement relative to the holding web, so that the contact pressure against the abovementioned stop surfaces is maintained as a result.
  • the same result is achieved if the grooves are not attached to the insulating web but, according to another embodiment of the invention, to the corresponding surface of the supporting web.
  • an even stronger contact pressure can be achieved according to a further embodiment of the invention in that the insulating web is provided with trapezoidal (conical) legs that taper outwards. If these insulating webs are used with their legs in the undercut part of the groove and pressed against the holding web with the deformations of the supporting web, then a full contact of the insulating web in the undercut part of the groove is achieved due to the wedge effect associated with the trapezoidal shape. The same result can also be achieved in that the undercut part of the groove itself has a trapezoidal shape. Likewise, both the leg of the insulating web and the undercut part of the groove can have a trapezoidal shape.
  • the deformations are only applied individually and at intervals to the support web, they can protrude so far that the insulation web is also deformed at the relevant points. If this is the case, the profile rails can never move against each other in the longitudinal direction. The deformation of the support web can also go so far that the support web shears from its base in the deformation region. The same applies if the deformations are not applied to the supporting webs but to the L-shaped holding webs.
  • Such deformations are preferably produced with tools, the tip of which has the shape of a triangular or polygonal prism, a prism surface running parallel to the inner surface of the profile rails or the groove base surface.
  • This embodiment brings about a permanent connection or clamping between the insulating webs and the profile rails.
  • the bending edge between the undeformed part and the notched part of the respective support web can run parallel to the longitudinal axis of the profile body.
  • Another embodiment provides that the bending edge runs perpendicular to the inner surfaces of the profile rails or to the base of the groove. If the deformations are then additionally designed such that the bending direction of the notched parts alternates, this results in an advantageous pawl effect in relation to the longitudinal stroke in both directions of the longitudinal axis of the profile body.
  • a further embodiment provides that the deformations are achieved with tools, the tips of which have the shape of a triangular or polygonal pyramid, the base of the pyramid running parallel to the inner surface of the profile rails or of the base of the groove.
  • the deformations can be configured so that the inclination of the bending edge is of the notched parts against the profile body axis less than 9 0 °, and the inclination direction between Benach beard deformations alternate, so that an advantageous pawl effect is achieved in this embodiment.
  • Deformations on two mutually opposite supporting webs (or holding webs) are essentially the same. This ensures that any tilting forces that occur on one insulating web are compensated for by corresponding tilting forces that act on the other insulating web. This prevents unilaterally occurring tensions in the profile body and prevents it from warping.
  • a sufficiently rigid profile body is created when the permanent deformations in the support web are sufficiently strong. Such sufficiently strong deformations can, however, be provided in the support web if the insulating strips have sufficient play in the grooves or if the deformations can be pressed or pressed into the material of the insulating strips.
  • insulating strips which are made of hard material that resists deformation.
  • a hard material can be hard paper, for example, which is characterized by high heat resistance.
  • the profile body of the type described at the outset is designed such that the profile body is a sufficiently rigid structure even when there is a high degree of fit between the profile rails and the insulating strips and / or when using insulating strips made of hard material.
  • each Insulating strip has a continuously rounded or beveled edge area directed against the projecting deformations, against which the deformations rest.
  • the desired pressure on the edge area can also be achieved by deforming a web which does not abut the insulating strip before deformation, the deformation of this web being such that the end face thereof is in contact with the edge area.
  • a part is worked out in the section of the profile rail opposite the edge area of the insulating strip, which part is pressed against the edge area like a plow to form the deformation.
  • This deformation can also be carried out continuously or in sections.
  • the part can be pressed against the edge region of the insulating strip, in particular if it has already been formed during the manufacture of the profile rail, by means of a wedge that starts up.
  • the part can be made in the manner of a plow with the insulating strip already inserted from the insulating rail in one operation and pressed against the edge area.
  • the surfaces of the web or of the part facing the edge region can be provided with transverse corrugations, which bear against the insulating strip and, if necessary, press in, as a result of which the shear strength of this composite arrangement is increased.
  • the insulating strip is pressed into the L-angle by the deformations.
  • the support webs lie firmly against the insulating webs over their entire length in the region of their end faces.
  • the abutment of the upper part of the support webs brings about a further strength.
  • a sealing or adhesive mass is located in the space between the insulating web and the inner surfaces of the undercut grooves.
  • This mass can be permanently elastic or solidified. It seals the longitudinal joints, which in any case leads to additional anchoring of the insulating web when an adhesive is selected.
  • a material that softens at elevated temperature is particularly suitable for the manufacturing process.
  • ribs are attached in the inner surfaces of the profile rails in the longitudinal direction, the wall thickness of which is at least the same, preferably greater than the wall thickness of the support webs.
  • this profile body is preferably first loosely assembled from profile rails and insulating webs. The deformations are then applied inside the cavity, which is enclosed by the profile rails and the insulating webs, on the support webs, and possibly also on the holding webs. In principle, however, it is also possible to apply deformations not from the cavity but from the outside if the grooves are arranged in a corresponding manner on the profile rails.
  • the deformations can be produced one after the other. However, it is advisable to simultaneously impress mutually opposing deformations on the support webs so that the forces exerted by the deformation tool on the profile body cancel each other out and no torsion or twisting of the hollow profile can occur.
  • the profiled rails are clamped apart from one another before the deformation is impressed, so that the insulating webs lie firmly against the stop faces of the undercut grooves. If, in this state, the deformations are hammered in at the base of the supporting webs with a wedge or a mandrel, then insulating webs receive a pressing force against the stop surfaces, so that the insulating webs remain firmly in contact with these stop surfaces.
  • the profile rails are stretched so far apart that the legs of the insulating webs open elastically. After applying the deformation and relaxing the profile rails, the elastic forces of the insulating webs then contribute to the fact that their legs lie snugly against the stop faces of the undercut groove.
  • an expansion block is preferably used which is cushioned and which pushes the profiled rails apart, so that the legs of the insulating webs abut the abutment surfaces of the grooves and, if necessary, open elastically if the springs of the expansion block are correspondingly strong.
  • Arms are attached to the expansion block, which are provided with bulges. These arms are driven apart with a spreading wedge so that the bulges of the arms hit the support webs and cause the deformations there.
  • An expansion block with four attached arms is preferably used as the deformation tool, so that each time the expansion wedge is actuated, four deformations are achieved simultaneously.
  • the deformations in the support webs are preferably stamped in such a way that their flank lying at the base of the support web is flush with the inner surface of the profile rail. In this case, no damage to the profile rails can occur during the formation of the deformations.
  • the expansion wedge and the articulated arms are designed so that the forces occurring when driving in the expansion wedge are directed essentially against the support webs and only a small force component acts on the inner surfaces of the profile rails.
  • this small force component in the direction of the profile rails it is achieved that the bulges of the articulated arms which cause the deformations attack the base of the support webs, on the other hand this force component is so small that damage to the profile rails cannot be concerned.
  • a conical expansion wedge provided with a toothing, in particular with a screw thread, is screwed into a correspondingly designed toothing at the end of the articulated arms.
  • the deformation tool is pushed forward on a support rod step by step through the cavity of the loosely preassembled profile body and spread with each step.
  • the length of the support rod should be at least equal to the length of the profile body to be manufactured. Accordingly, it may be expedient to advance the deformation tool from both ends of the profile body only to the middle.
  • the deformation tool has an expansion block, a high frictional resistance must be overcome when the deformation tool is pushed in and out into the cavity. Accordingly, according to a further embodiment of the method according to the invention, it may be advantageous to first provide the lower profile rail with the insulating webs in order to produce the profile body, then to insert the deformation tool in such a way that its support rod is in the "groove” formed by the lower profile rail and the insulating webs. lies, the actual deformation tool (spreading block with arms) protrudes beyond this "groove”. Then the upper profile rail is pushed with its grooves over the insulating bars, so that a loosely pre-assembled profile body arises.
  • the profile body is then pushed over the deformation tool, this deformation tool gradually producing deformations on the support webs.
  • the mutual distance between the individual deformations can advantageously be determined by the speed at which the profile body is moved against the deformation tool and by the frequency with which the deformation tool is actuated.
  • the applicator has an outlet nozzle which is open towards the intermediate space in the working position.
  • the nozzle is sealed off from the cavity of the profile body, so that the sealing compound or adhesive compound is only pressed into the space between the insulating web and the inner wall of the groove.
  • the application device can, for example, be inserted into the preassembled profile body and driven through it. Due to the pressure of the flowable mass, the insulating webs are pressed against the stop faces and the end faces of the undercut grooves, so that a tight seal is achieved there.
  • a solid or pasty strip from the mass can first be applied to the inside of the insulating webs and then z.
  • a scraper plate or a roller that seals on the inner surfaces of the rails or the surfaces of the supporting webs abut and is passed longitudinally through the cavity of the preassembled profile body, pressed into the intermediate space.
  • the pasty strip can also be applied to the insulating webs before the loose pre-assembly of the profile body, so that it is possible, for. B. use a powerful glue coating system.
  • the applied mass must be so firm that it survives the pre-assembly of the profile body. It is therefore advisable, according to an embodiment of the associated method according to the invention, to use a mass which can be softened by increasing the temperature, e.g. B. a hot melt adhesive.
  • a displacement tool z. B. a roller used, which is itself heated and with which the applied mass is softened.
  • This displacement tool can be integrated with the deformation tool, e.g. B. in the form of a corresponding projection on the block of the deformation tool carrying the spreading arms or in the form of a projection on an expansion profile which is pulled through the cavity of the profile body for the formation of the deformations.
  • the present invention specifies a production method in which the deformation of the support webs is achieved with the aid of two deformation rails, these deformation rails being inserted into a loosely preassembled profile body and then being pressed apart with the aid of an expanding wedge. As a result, the deformation rails are squeezed against the supporting webs and this is thereby pressed against the insulating webs.
  • This method can not only be used to produce such profile bodies in which the support webs are provided with individual, spaced-apart deformations, but it can also be advantageous for use the production of profile bodies according to the prior art, in which the support webs are bent or bent against the insulating webs.
  • the deformation rails can consist of two metal strips, the width of which is dimensioned such that they rest on the inner surfaces of the support webs lying towards the cavity.
  • the ligaments and with them the support webs are then bent outwards.
  • these two deformation rails are connected at their front end by an elastic or articulated bridge.
  • This bridge is kept so flat that it fits into the space between the two supporting webs.
  • This articulated bridge serves on the one hand as an aid for inserting the deformation rails into the cavity of the preassembled profile body, on the other hand it holds the deformation rails together between the individual operations, so that the package formed from the deformation rails and the pull rod located between them is simply guided can be.
  • the deformation rails have corresponding bulges.
  • the deformation rails are inserted in such a way that these bulges abut the support webs.
  • These bulges of the deformation rails can, for example, be continuous ribs which are attached transversely to the longitudinal direction of the deformation rails.
  • the cross section of these ribs can in turn be of any shape, for example triangular, trapezoidal or semicircular: if the deformations are achieved essentially in the area of the base of the respective support web, the bulges protrude further at the edges of the deformation rails than in the middle thereof.
  • these bulges can then be designed as individual teeth, but transitional forms between the rib-shaped configuration and the individual teeth are also possible, in that such a rib, for example, protrudes further on the edges of the deformation rails than in the middle thereof.
  • these teeth can have the shape of a triangular or polygonal pyramid or a triangular or polygonal course dimension or also a truncated cone.
  • deformation rails can advantageously be used for this purpose, which are bevelled on the edges lying to the support webs. If only a beveling of the support webs is desired, this bevel is continuous over the entire length. If, in addition to the folding, the application of individual deformations in the base area of the support webs is desired, these are bevels interrupted by the bulges arranged at a distance. These bulges can run up to the edge area of the deformation rails, but they can also end a small distance in front of it.
  • the deformations will not protrude furthest in the base region of the support webs, but in an area closer to the end face of the support webs.
  • the deformation rails and the expanding wedge are expediently designed such that they can be inserted together as a package into the cavity of the profile body.
  • the deformation rails have recesses in which the expansion wedge lies when it is inserted, so that the entire arrangement fits into the cavity.
  • a tie rod is attached to a corresponding holder of the deformation rails.
  • the deformation rails may have holes at their ends projecting beyond the profile body, into which, before the beginning of the expansion process, for example, bolts suspended from an abutment are inserted, for example with the aid of a compressed air cylinder.
  • the insertion of these bolts can also be done in such a way that the ends of the Verfor provided with the holes due to the expansion process tion rails are pressed outwards and thereby engage in corresponding abutments.
  • This sequence of movements can be controlled very easily automatically, so that this production sequence can still be designed very efficiently.
  • This invention also proposes several types of deformation tools which are advantageously used in the production of the heat-insulating profile body.
  • such a deformation tool consists of a block on which arms provided with bulges or thorns are attached.
  • this block with the attached arms is inserted into the cavity formed by the profile rails and the insulating webs, and the arms are pressed apart with a spreading wedge, so that the bulges or the mandrels are applied press the desired deformations into the support webs.
  • the shape of the block is designed so that it fits fairly precisely in the cavity of the loosely mounted profile. It is more expedient, however, if this block is designed as an expansion block, so that it presses the two profile rails apart with spring action, since manufacturing tolerances can then be compensated for with such a tool.
  • Return springs are attached to the arms of the deformation tool, so that each actuation of the expansion wedge releases the mandrels of these arms from the deformations generated and the arms return to their starting position.
  • a support rod is attached to the block so that the deformation tool can be pushed or pulled through the hollow profile.
  • a push rod is also attached to the expanding wedge, on which, for example, an eccentric engages, so that the arms of the deformation tool are pressed apart at a frequency corresponding to the rotational speed of the eccentric.
  • die'Trägerstange is formed as a tube and that "is passed through the push rod, to the expanding wedge actuated through this tube and through the tube attached to the block.
  • This configuration allows a loosely preassembled profile body to be automatically pushed onto the deformation tool, for example with a conveyor belt.
  • the support rod serves on the one hand to push the deformation tool through the loosely mounted profile body. It also has the function, when actuating the expanding wedge, of absorbing the thrust effect which the expanding wedge exerts on the entire deformation tool and thus preventing the deformation tool from slipping or shifting during this expansion process. According to a further advantageous embodiment of the deformation tool according to the invention, it is also possible, however, to do without such a support rod by using the profile itself as an abutment.
  • the push rod attached to the expansion wedge is held by a spring on the expansion block and is pressed by this spring against the arms, so that the bulges or mandrel tips attached to these arms bite into the profile; this prevents displacement of the deformation tool against the profile rails when the expansion wedge is actuated. If the expanding wedge is then pulled out of the arms again, a stop on the push rod ensures that it does not slip out of the guide of the block.
  • a further advantageous embodiment of the deformation tool used according to the invention takes into account the fact that the profile bodies in production have the most varied shape and thus also the most varied cavity cross sections. Since the deformation tool must be adapted to this cavity cross section, it is desirable to be able to remove the parts causing the deformation from the support rod and the push rod. This is made possible by the push rod being attached to the block in one brought coupling member ends and that on this coupling member, the support rod and an extension rod for the push rod are removably attached.

If a diamond-shaped expansion wedge is then driven into this recess, the articulated arms are pressed both against the inner surfaces of the profile rails and against the supporting webs. Appropriate choice of the diamond-shaped cross section ensures that the contact pressure against the inner surfaces of the profile rails is smaller than the pressure directed outwards against the support webs.
  • the diamond lies with its longer diagonal in the direction of the pivot axes of the arms.
  • the wedge action is directed primarily outwards against the support webs and, with a smaller thickness, against the inner surfaces of the profile rails.
  • Another embodiment of this deformation tool provides that the articulated arms are provided with springs or are themselves designed to be resilient, so that they rest on the inner surfaces of the profile rails due to the spring action.
  • the expanding wedge ko nisch trained and is provided with a helical toothing, and that a matching toothing is attached to the arms. The arms are then spread in such a way that the cone of the expanding wedge is screwed into the toothing on the arms, whereby these arms open and produce the desired deformations.
  • Another deformation tool which is also used with good results, consists of a cuboid block which has slots on its longitudinal edges, in which pins are movably inserted. These pins end with their heads in corresponding recesses of a push rod which is guided through it, centered on the longitudinal axis of this block. Depending on the position of the push rod, the tips of these pins extend beyond the contour of the block or recede behind this contour. In a reciprocating movement of the S chubstabes thus jumping for these peaks and back, so that the desired deformations are caused in this way.
  • Another deformation tool has, as the deformation-causing elements, disc wheels which are provided with individual spikes on their circumference. When these disc wheels roll along the support webs, the mandrels press into these support webs and cause the desired deformations.
  • This deformation tool consists in particular of two pairs of disc wheels, a gear wheel being arranged between each such pair. These gears mesh with each other.
  • the disc wheels are also provided with recesses V adapted to the mandrels, so that when the disc wheels rotate against one another, the spikes of one disc wheel engage in the recesses of the other disc wheel, so that these disc wheels can rotate against one another without mutual interference.
