Description

The present invention relates to a component for thermal insulation according to the preamble of patent claim 1.

Various embodiments of components for thermal insulation with a separate pressure force distribution element are already known in the prior art, which ensures that the pressure force can be transmitted over as large a surface as possible between the pressure element and the adjacent component. Thus, in the early days of such components for thermal insulation, pressure elements had a pressure rod passing through the insulating body level and pressure plates welded at the end to the pressure rod, see, for example DE-A-41 03 278 ,

In the subsequent period, however, have also been proposed designs in which the pressure webs and the pressure force distribution elements were arranged to be movable relative to each other, as for example in the DE-A-40 09 987 is described where the pressure ridge consists of a metal rod to which end face cuff-like pressure force distribution elements connect and the pressure bar and the two pressure force distribution elements are hinged together - at least after a provided for assembly purposes mutual positional protection is eliminated. This position assurance consists of frontal extensions of the pressure ridge, which extend into corresponding openings of the sleeve-like pressure force distribution elements and are fixed there rivet-shaped. This ensures that these three elements, so the pressure bridge and the terminal pressure force distribution elements retain their predetermined or intended position until after joining the adjacent components and up to the first actual load case, which leads to a lateral shearing movement of these rivet-like extensions. The disadvantage here, however, that the shearing can not be flush with the frontal surface of the pressure element and that the opening for the position assurance projection is provided exactly in the contact area of the pressure bridge to the pressure force distribution element, so there is also no optimal movement and force introduction surface available. Consequently, in this from the DE-A-40 09 987 Although known embodiment, the pressure force distribution element extensively transmit compressive forces and initiate an optimized in terms of thermal pressure web with minimum cross-section as well as Druckkraftverteilungselemente and pressure ridges mutual relative movements through the articulated join almost free of lateral forces, without causing a deterioration of the function in the pressure force transmission , However, the pressure force transmission through the disturbed or less optimized facing each other bearing surfaces in need of improvement.

In the prior art is from the DE-A-196 27 342 a further embodiment of a pressure element with pressure force distribution element, in which the pressure force distribution element consists of a plate-shaped member which is connected by a dovetailed form-fitting connection with the end face of an associated pressure bridge and thus can follow in the horizontal direction relative movements almost without lateral force, while maintaining the pressure force transmission function. The said dovetail-shaped design of the positive connection between the pressure force distribution element and pressure bridge while on the one hand ensures a good positional safety in the installation and transport state, but it leads due to the numerous large-scale investment areas between pressure force distribution element and pressure bridge very quickly to constraints, especially if no exactly horizontal relative movement between the pressure element and associated component takes place, but for example, a slight inclination or inclination. The resulting constraints lead to corresponding shear forces up to destruction of the pressure ridge or the pressure force distribution element in the mutual investment area.

Furthermore, it should be noted that it has now been possible by the known solutions with additional pressure-force distribution element to optimize the pressure transmission by generic components for thermal insulation and yet not or only slightly hinder temperature-related relative movements between the adjacent components. For all aspired Optimization of the compressive force transfer while maintaining mobility has, however, in the past, brought further attention to further optimization in terms of thermal insulation, which has been the main reason for developments in the field of thermal insulation since the beginning. The cross-section reduced pressure ridges of the prior art sprang up already based on the knowledge that better thermal insulation is accompanied by the smallest possible cross-sectional area in the region of the pressure ridge. In other words, the smaller the cross section of a given print web material, the lower the heat transfer, so the transmitted heat through the print bridge.

However, a certain amount of frontal force application surface is required to maintain the required pressure force transmission. For this reason, printing elements are known in the prior art, in which the pressure bridges are provided at a reduced cross-sectional area in a central area terminal again with a larger cross-section, see, for example EP 1 225 283 A2 ,

In the WO-A-2008 113348 a component for thermal insulation with integrated pressure elements is proposed, which consist of several firmly interconnected sections in order to adapt the individual sections to various requirements. In this case, for example, the respective end portions, which act as pressure force distribution element, to improve the thermal insulation of a material with low thermal conductivity, eg foam or lightweight concrete and have a thermal conductivity between about 0.2 and 2.0 W / mK.

On this basis, the present invention seeks to provide a device of the type mentioned above, which is optimized with regard to the pressure force transmission on the one hand and the thermal insulation on the other hand while maintaining the recording of relative movements in the region of the pressure element.

This object is achieved by a device for thermal insulation with the features of claim 1.

According to the invention, the pressure force distribution element protrudes at least with its end face facing away from the pressure ridge into the adjacent component and has a surface at this end face remote from the surface with a coefficient of friction which is increased in particular by a profiling. As a result, the bond between the pressure force distribution element and adjacent component is improved, resulting in the significant advantage that the pressure force distribution elements may extend within the component to far down to almost or entirely at the lower edge, without having to comply with the otherwise to be considered minimum concrete coverage. As a result, the pressure element may be arranged far down inside the structural element for thermal insulation, which results in a larger lever arm compared to the tensile reinforcement than in comparable cases, in particular with pressure elements made of steel.

Advantageous developments of the invention are the subject of subclaims, the wording of which is hereby included by express reference in the description in order to avoid unnecessary text repetitions.

According to the invention, the compressive force distribution element is made of a material having a thermal conductivity λ which is lower than 2.0 W / mK, so that it has a thermal conductivity which is lower, that is better than the commonly used reinforced concrete. This requirement is based on the finding that the adjacent component, which usually consists of a reinforced concrete, in particular of a concrete of strength class C20 / 25 according to DIN 1045-1 or higher, a pressure force introduction area for the pressure element is to be connected upstream, which also improved significantly Has thermal insulation property. In other words, the pressure element according to the invention provides a pressure force introduction region for the adjacent component in the form of the pressure force distribution element, thus replacing the corresponding region of the adjacent component with its own region having optimized properties. And in order for this not only leads to an improved pressure force introduction, but also to improved thermal insulation properties, the pressure force distribution element according to the invention with a thermal conductivity λ of less than 2.0 W / mK configured.

It is particularly preferred if the material of the compressive force distribution element has a thermal conductivity λ which is lower than 1.6 W / mK and in particular lower than 1.0 W / mK. It is already known from the prior art, instead of conventional pressure elements made of steel, especially stainless steel, to use high-strength or ultra-high-strength concretes for optimizing the thermal insulation, which not only have a better load capacity and thus require a smaller cross-section to the required pressure force transmission, but also a lower thermal conductivity than steel. Thus, if high-strength or ultrahigh-strength concrete or mortar is used not only as the material of the pressure bridges, but also for the material of the pressure force distribution element, then the load-bearing capacity can be improved not only via the improved pressure force introduction into the adjacent components, but also the thermal insulation in the force introduction area ,

It is particularly advantageous for the assembly and assembly of the component for thermal insulation when the pressure element has a position securing element and the pressure force distribution element can be positioned on the pressure ridge via the position securing element. As a result, it is possible in a particularly advantageous manner to continue operating the separation of functions already started by the separate pressure force distribution element and to provide an additional position securing element, so that neither the pressure ridge nor the pressure force distribution element itself must provide for securing the position, but that this has a separate function Component takes place.

In this way, the pressure bar and pressure force distribution element can be further optimized with regard to the pressure force transmission function intended for them. For example, the pressure element may have the smallest possible cross section, which leads to a correspondingly reduced heat or cold transmission through the component joint or the insulating body arranged therein. But at the same time to improve the pressure force transmission, the pressure bar frontally does not have even the largest possible pressure force introduction surface, but this can be ensured by using the separate pressure force distribution element, which can be designed correspondingly large area. So that now the pressure force transmission between the pressure bridge and separate pressure force distribution element can take place in an optimal manner, the position securing element provided according to the invention ensures that both Components are installed in their intended mutual orientation and position, this position assurance element can also provide for any desired relative movement between pressure force distribution element and pressure bridge.

Advantageously, therefore, the pressure force distribution elements can be fixed by a respective position securing element in the region of the end face on the pressure ridge, wherein expediently the actual fixing takes place outside the pressure force transmission region, ie in particular outside the end faces.

A particular advantage arises when the position assurance element consists of a casting mold and the pressure force distribution element and / or the pressure bridge consists of an insertable into the mold curing and / or settable filler, in particular of a cementitious, fiber-reinforced building material such as concrete, such as high-strength or ultra-high strength Concrete or as high-strength or ultra-high-strength mortar or from a synthetic resin mixture or from a reaction resin. This ensures that the position securing element and the pressure force distribution element on the one hand and / or the position securing element and the pressure bridge on the other hand are precisely matched to one another. If the mold is then installed in a preferred embodiment together with the pressure force distribution element and / or the pressure ridge, thus forming the position assurance element a lost mold, it can be ensured that the optimal investment of the pressure force distribution element and / or the pressure ridge on the position assurance element maintained even after installation is and the mold provides a tolerance-free to the surface of the pressure force distribution element and / or the pressure bar optimally adapted surface.

Further advantages result from the fact that the position securing element forms a sliding layer between the pressure bridge and the pressure force distribution element; Thus, if already the position securing element is already present anyway, it can also assume the function of a sliding layer according to the invention, which is often already present in the case of movably mounted printing elements. Since the sliding layer must also be secured in position on the pressure element in the customary applications, it is particularly advantageous in the present case if this is achieved by the position securing element according to the invention can take place, so the sliding layer itself consists of the position assurance element. In this context, a sliding layer is not to be understood as meaning any thin-layered application of a coating on pressure ridge and / or pressure force distribution element, but rather a physical layer which, according to the invention, may consist of the position-securing element and in particular of the mentioned casting mold. The overlay usually has a layer thickness of the order of a few tenths of a millimeter and preferably 0.5 mm and above.

It is within the scope of the present invention, when the position assurance element consists of a mold for the pressure element, as for example from the EP-A-1 225 282 A2 is known, only that now meet the mold, the further function of the position assurance element and this must be connected to a separate pressure force distribution element.

It is possible and regularly useful to produce both pressure ridge and pressure force distribution element by one and the same mold. Likewise, it is of course also possible to produce only one of the two elements through the mold and prefabricate the other element, for example.

As already mentioned, the pressure bridge and the pressure force distribution element can be connected to one another with the interposition of the position assurance element, in which case the position assurance element can form a sliding layer for the pendulum or pivoting movement between pressure bridge and pressure force distribution element.

In this context, it is recommended that the pressure bar on its front side facing the component in a vertical section and / or in horizontal section concave or convex curved contact profile and that the pressure force distribution element adapted in vertical section and / or horizontal section in the form of the contact profile opposite Has convexly or concavely curved force introduction surface, so that pressure ridge and compressive force distribution element abut each other flat along a curved surface. If this curvature has a circular arc shape, this allows an articulated movement of the pressure bridge relative to the pressure force distribution element along the circular arcuate surface provide.

It is particularly advisable if the pressure force distribution element is arranged completely or at least predominantly in the adjacent component; then the pressure ridge can be limited to the region of the insulating body and the pressure force distribution element be moved by positive or cohesive connection with the adjacent component, so that then the relative movement is preferably carried out in the edge region of the insulating body, ie in the interface between insulator and component. For this purpose, it is therefore recommended that the pressure bar with its adjacent component facing end face terminates at least approximately flush with the Isolierkörperseitenfläche.

Alternatively, of course, the pressure force distribution element may also be arranged in the area of the component joint, ie in the insulating body region, whereby it would nevertheless be advantageous in this embodiment to connect the pressure force distribution element with the adjacent component so firmly that any relative movement between the adjacent components from the pressure force distribution element the contact area between the pressure bridge and compressive force distribution element is transmitted and thus takes place in the sliding layer area formed by the position assurance element, which is optimized in terms of mobility and accuracy of fit.

In this context, it is recommended that the position assurance element made of plastic, in particular HD polyethylene, which has optimum strength values with correspondingly optimal surface / sliding properties.

Furthermore, it is within the scope of the present invention for the position securing elements assigned to the two mutually opposite end faces of a pressure ridge to be connected to one another, for example by way of a connecting element, thereby providing a unit of pressure ridge, respectively connected pressure force distribution elements and associated position securing elements with connecting element Unit can be put together in the insulating body area, which is for them is provided. Alternatively, it is of course also possible to arrange the items in succession in the insulating body, for example, if the position assurance element consists of a mold and the respective element is to be made only in the inserted state of the position assurance element in the insulator. Finally, it is also possible by the present invention to provide a common position securing element for two mutually horizontally adjacent, in particular juxtaposed pressure webs, which can be provided by the common position assurance element either for each print web a separate pressure force distribution element or a common pressure force distribution element for the two adjacent pressure bridges.

In the FIGS. 2 and 3 is the lower portion of a device 10 according to the invention shown with a parallelepiped-shaped insulating body 16 and extending through the insulating body in the horizontal direction and perpendicular to its longitudinal extension pressure webs 19a, 19b, wherein in the FIGS. 2 and 3 shown dashed lines 19a, 19b are arranged adjacent to each other in the horizontal direction, extending from an adjacent component A, for example, a ceiling plate to an opposing adjacent component B, for example, a balcony plate and for mutual pressure force transmission with arcuately curved end faces 22a, 22b, 22c, 22d projecting slightly in the planes of the components A, B with respect to the insulating body plane.

According to the invention, a pressure force distribution element 20a, 20b is now provided in the region of the components A, B in the region of the end faces of the pressure elements 19a, 19b, which serves for the introduction of pressure force or pressure force discharge between the pressure elements 19a, 19b and the adjacent components A, B. In the embodiment shown, two pressure webs 19a, 19b and two pressure force distribution elements 20a, 20b together form a pressure element 12. For the sake of completeness it should be noted that it is also within the scope of the invention that pressure elements only one pressure bar and a total of two each end face connected to the pressure bar Compressive force distribution elements have.

The pressure force distribution elements 20a, 20b are substantially flush with the side surfaces of the components A, B and thus extend in the installed state along the side surfaces 21 a, 21 b of the insulator 16. Only in the area of the printing elements they jump back slightly from this flush extension and are there adapted to the circular arc-shaped curved end faces 22a, 22b, 22c, 22d of the pressure elements 19a, 19b and thus have adapted thereto complementary circular arc-shaped recesses 23a to 23d.

As in particular from the top view in FIG FIG. 3 It can be seen that the pressure elements lie with their circular arc-shaped convex end faces flat on said recesses of the pressure force distribution elements and go with this an articulated connection, by which it is possible that the components A and B move parallel to each other in the horizontal direction and in this case the Pressure elements 19a, 19b follow the displacement movement by slight inclination almost free of lateral force.

It is essential to the invention that the pressure force distribution elements consist of a material which has a thermal conductivity λ which is lower than 2.0 W / mK. In the embodiment shown in the drawing, an embodiment is shown with pressure-force distribution elements, which consist of high-strength concrete and thus a thermal conductivity in the order of only 0.8 W / mK. In contrast, the in-situ concrete of the adjacent thereto concrete component A, B has a thermal conductivity λ of about 2.1 W / mK. From this it is quickly and easily recognizable that the pressure force distribution element according to the invention represents an insulating layer for the adjacent component, so it already in the pressure web already significantly reduced thermal conductivity (in the present embodiment, the pressure bridges made of high-strength concrete with a thermal conductivity in the order of only 0 , 8 W / mK) up to the area of the adjacent component.

It is also essential to the invention that position securing elements 11a, 11b are arranged between the pressure elements 19a, 19b and the pressure force distribution elements 20a, 20b, which position and preferably also fix the pressure webs 19a, 19b and the pressure force distribution elements 20a, 20b. These position securing elements 11a, 11b consist in the embodiment shown of a mold for the pressure webs 19a, 19b and for the pressure force distribution elements 20a, 20b and they correspond to the position assurance elements 1a, 1b FIG. 1 , which are described in detail below.

In the embodiment of the FIGS. 2 and 3 the position securing elements form a sliding layer between the between the pressure elements 19a, 19b and the pressure force distribution elements 20a, 20b, through which the static friction in the mutual contact region of the pressure webs and the pressure force distribution elements is significantly reduced, so that a sliding pivoting movement without major adhesion effects and thus caused transverse forces is possible.

In the FIGS. 2 and 3 the position securing elements 11a, 11b functioning as a casting mold for the compressive force distribution elements can only be seen as outlines of the compressive force distribution elements 20a, 20b, whereby it can be seen that these overall have an approximately cuboid outer contour with the arcuate recesses serving as sliding layers 14a, 14b, 14c, 14d where the corresponding end faces 22a to 22d of the pressure elements 19a, 19b on the one hand and the opposite recesses of the pressure force distribution elements 20a, 20b, namely the local surfaces 23a to 23d bear.

In FIG. 1 is a part of a device according to the invention for thermal insulation shown, namely a position assurance element 1a, 1b, which consists of a mold 13 with a cavity 2a, 2b, in which concrete, in particular high-strength or ultra-high-strength concrete for a not in FIG. 1 not shown pressure force distribution element can be filled, as well as with a cavity 7a, 7b, in which concrete, in particular high-strength or ultra high-strength concrete for a in FIG. 1 not shown, can be filled.

The mold 13 has not only the cavities 2a, 2b, 7a, 7b of the position-securing element, but also curved surfaces 3a, 3b, 3c, 3d, which are used as the mold part of two in FIG. 1 not shown pressure elements act, more precisely for the end faces of the two printing elements. In this curved surface area 3a-3d, the position securing element 1a, 1b thus forms a sliding layer 4a, 4b, 4c, 4d for the force transmission and contact area between pressure force distribution element on the one hand and the individual end faces of the pressure bridge on the other. Due to the curved circular arc shape of these sliding layers 4a to 4d both on the pressure webs facing surfaces 3a to 3d and on the opposite, the pressure force distribution element associated surfaces 5a to 5d are the pressure webs and the associated pressure force distribution elements hinged to each other and can perform relative movements to each other along the circular arc shape and thereby ensure that the compressive forces continue can be transmitted without lateral force over the sliding layer between pressure bridge and pressure force distribution element.

Next is in FIG. 1 an insulating body portion 6 is shown, the in FIG. 1 not shown in particular bears on its underside and partially by corresponding recesses 7a, 7b can also act as a mold for the pressure bars by the recesses 7a, 7b of the pressure bars intended shape correspond. The mold for the above the Isolierkörperteilbereichs 6 extending portions of the pressure bridges are in FIG. 1 also not shown. Not shown in the drawing is a connecting element which serves to connect the two position securing elements 1a, 1b with each other. This can, for example, in the horizontal direction rod-shaped extending from a position assurance element 1 a to the other position assurance element 1 b through the insulating body 6. As a result, the distance between the front-side casting mold surfaces 3a to 3d and thus the length of the associated pressure webs is predetermined, which corresponds approximately to the width of the insulating body 6.

The in FIG. 1 Not shown connecting web corresponds to FIG. 3 a connecting web 18 which is arranged between the two position securing elements 11 a, 11 b and held by the pressure webs 19 a, 19 b between the load distribution elements 11 a, 11 b during manufacture, transport and installation and so in the predetermined orientation and position opposite the pressure force distribution elements 20a, 20b are arranged.

FIG. 4 shows further parts of another embodiment of a thermal insulation element according to the invention with alternative position assurance elements 31 a, 31 b, with a two parallel pressure webs 39 a, 39 b and two end pressure distribution elements 30 a, 30 b existing pressure element 32 and an insulating body 36 in a sectional plan view. Although the alternative position securing elements 31 a, 31 b also serve as a casting mold 33 a, 33 b with cavities 34 a, 34 b for the pressure force distribution elements 30 a, 30 b, but not for the pressure webs 39 a, 39 b. Each position securing element is designed in several parts and consists of a along the Isolierkörperaußenseite 36 extending wall 41a, 41b, from the pressure webs 39a, 39b frontally acting sliding layers 42a, 42b, 42c, 42d and from an additional horizontal section U-shaped profile body 43a, 43b. On the bottom, finally, the cavities of a in Fig. 4 Limited floor area, not shown.

The pressure bridges, however, consist of without involvement of the mold 33 and the position assurance elements 31 a, 31 b prefabricated concrete elements. They are in the area laterally of their end faces 42a, 42b, 42c, 42d of the position assurance elements 31 a, 31 b embraced and set in the predetermined position relative to the pressure force distribution elements 30a, 30b.

In FIG. 5 Now, a device according to the invention for thermal insulation 51 is shown completely in side view with a cuboid insulator 56 which extends along the left between two components A and B gap in the horizontal direction, and with reinforcing elements in the form of tie rods 52, transverse force bars 53 and pressure elements 58th Die Tension rods and the transverse force rods are made in the usual manner of steel, namely in the region of the joint between the two components A and B, ie in the region of the insulating body 56 made of stainless steel and in the area far outside of the insulating body, ie in the region of the components A. and B of reinforcing steel, as indicated by the different hatching of the two reinforcing bars in FIG. 5 is indicated. They are arranged in the usual manner in the prior art relative to the thermal insulation component, namely in the case of tension rods in an upper region of the insulating body, the so-called tension zone, in the horizontal direction perpendicular to the longitudinal extent of the insulating body and in the case of transverse force rods starting from the tensile zone of the supporting member obliquely inclined down through the insulating body into the lower pressure zone and from there outside of the insulating body again vertically up to the tensile zone of the supported component.

In contrast, the pressure elements 58 are formed differently in comparison to the known pressure elements. They consist of extending through the insulating body 56 in the horizontal direction and perpendicular to the longitudinal extent of pressure webs 59 extending in the horizontal direction of an adjacent component A, such as a ceiling plate to an opposing adjacent component B, for example, a balcony slab, and from the front side of the pressure bars 59 arranged pressure force distribution elements 60a, 60b. The pressure force distribution element 60b associated with the component B serves to absorb the pressure force of the supported component B and to introduce it into the pressure ridge 59, whereas the pressure force distribution element 60a assigned to the component A serves to transfer the pressure force from the pressure ridge 59 into the component A and initiate there ,

The pressure force distribution elements are made of high-strength or ultra high-strength concrete and thus have the inventive favorable thermal conductivity. In the embodiment FIG. 5 the pressure ridge 59 is also made of the same material as the compressive force distribution elements 60a, 60b.

For the sake of completeness it should be mentioned that the transverse force rods 53 have in a conventional manner in their inclined course a Lagefixierungsmanschette 54, over which they are fixed relative to the insulating body 56 and / or the pressure bar 59, so as to unintentionally change their mounting position, in particular prevent shifting or twisting.

The FIGS. 6, 7, 8 and 9 show alternative embodiments of printing elements 68, 78 and 88 that more or less correspond to the embodiment of the printing element 58 of FIG. This in FIG. 6 shown pressure element 68 with the square pressure bar 69 and connected to the free ends of pressure force distribution elements 70a, 70b corresponds to the embodiment of the pressure element 58 from FIG. 5 , wherein the pressure force distribution elements 60a, 60b, 70a, 70b are each plate-shaped. In this case, the plate thickness influences the insulating behavior, by in this area - like FIG. 5 it can be seen - the material of the component A, B, so in particular the in-situ concrete is replaced with its poor thermal conductivity by the more insulating material of the pressure force distribution elements.

FIG. 7 shows a pressure element 78 corresponding to the pressure element 58 from FIG. 5 with the only difference that the pressure element 78 consists of two parallel pressure webs 79a and 79b, which cooperate with terminal common pressure force distribution elements 80a, 80b.

In FIG. 8 a pressure element 88 is shown, in which also a square pressure ridge 89, so a cylindrical pressure ridge with square vertical cross-section with plate-shaped pressure force distribution elements 90a, 90b cooperates. The difference with respect to the pressure elements 58, 68 is that the pressure ridge 89 has cross-sectional enlargements at its terminal free ends 94a, 94b so as to form a larger contact profile 93a, 93b for the adjacent pressure-force distributing element 90a, 90b. From the vertical section in FIG. 9 In this case, a circular segment shape in the mutual abutment region between the convexly curved contact profile 93a, 93b of the pressure ridge 89 and the oppositely concavely curved force introduction surface of the pressure force distribution element 90a, 90b can be seen, which enables an articulated movable contact and pressure force transmission in these regions.

From the vertical section one can also recognize profilings 91 on the end faces of the pressure force distribution element facing the respective component, which provide an improved bond between pressure force distribution element and associated component. This results in the significant advantage that the pressure force distribution elements may extend within the component down to almost or almost entirely at the lower edge, without having to comply with the minimum concrete cover otherwise to be considered. This results in the advantage that the pressure element may be arranged far down inside the structural element for thermal insulation with a larger lever arm with respect to the tensile reinforcement than in comparable cases, in particular with pressure elements made of steel.

In summary, the present invention has the advantage of providing pressure elements with additional separate pressure force distribution elements, which provide optimum pressure transmission and transmission, while optimally improved insulation by being made of a material having a thermal conductivity λ which is lower than 2.0 W / mK, preferably lower than 1.6 W / mK and especially lower than 1.0 W / mK.
