Abstract

The structural element, comprises an insulation body (2) with integrated reinforcement elements such as cross-bars (61, 62) engaged by installation modules (8). The insulation body is divided along a separating plane (23) which crosses the recesses for the installation modules. The installation modules can be inserted and fixed across the extension direction of the cross-bars into the recesses of the at least one insulation body half (22). The cross-bars are profiled such as ribbed in the area enclosed by the module. The modules can engage round the associated reinforcement element in its entire path through the insulation body.

Description

The invention relates to a component for thermal insulation between two components to be concreted, in particular between a building and a cantilevered outer part, consisting of one to be installed in between Insulating body with integrated reinforcement elements, in particular shear bars that are transverse to the longitudinal extent of the insulating body through this run and connected to both components are, the shear bars are bent so that they starting from one component diagonally from top to bottom run through the insulating body and then in the area of the pressure zone towards the other Protrude component, with built-in modules are provided, each with at least one shear bar in its grasp the oblique course within the insulating body and determine the installation modules in recesses of the Insulating body are arranged and fixed, and wherein these recesses adapted to the outer shape of the modules are.

The components of this type are used to two wall or ceiling elements, for example one cantilevered balcony with a corresponding false ceiling of a building, largely excluded of cold bridges to connect with each other. Serve here the reinforcement elements, the ones that occur Forces through the insulating body on the to transfer other component.

However, this power transmission is only sufficient ensures if the reinforcement elements are pretty accurate perpendicular to the longitudinal extent of the insulating body run so that the reinforcement elements next to the corresponding Tensile, compressive and vertical shear forces do not have to absorb horizontal shear forces, for which they are not designed. For this reason at least the reinforcement elements are made by the manufacturer on one side of the insulator with a parallel to the isolating distributor bar fixed by welding in the desired position, which ensures that the reinforcement elements not only during transport, but also on the Construction site in the vertical orientation relative to Insulating bodies remain.

However, this setting by distribution bars has the Disadvantage that the complete already at the manufacturer Component must be assembled, which is not just a Set the insulating body dimensions, but also the assembly and dimensioning of the reinforcement elements required. You always want an optimal design provide a component for thermal insulation, so results from the large associated with it Variety of variants an immense transport and storage effort.

To avoid this, the reinforcement elements embedded in built-in modules that improve the position fixation of the reinforcement elements in Serve insulating body. The reinforcement elements in particular play-free and form-fitting embracing Installation modules move the contact area between the reinforcement element and insulator on the outside of the built-in modules, making the contact surfaces corresponding the dimensions of the built-in modules and thus the stability of the storage of the reinforcement elements significantly increased in the insulating body becomes. Because while the soft insulation material of the Insulator only in small areas on the usually slim reinforcement elements and their movement due to its softness enlargement does not significantly hinder the mutual contact surfaces to a corresponding one Increase in the resistance of the insulation material. It finally follows from this that the reinforcement elements no additional fixation in the form of welded Distribution bars are required so that the assembly of the Component no longer at the manufacturer, but first can be done later at the customer.

The individual reinforcement elements and the Insulating bodies in all their variants delivered to the customer that you then according to the construction site Assembles requirements. This eliminates not just transporting the bulky completely assembled components from manufacturer to customer, but in addition, all kinds of warehousing Component variants. Instead of equipping the Components at the customer, it is also conceivable that a few regional assembly centers are planned with the help of trained installation personnel perform the assembly of the component, the Storage of the individual parts in these assembly centers done and the assembled components just transported to the customer on the short way Need to become.

In addition, the built-in modules can be used entirely on the Distribution bars are dispensed with, which were previously for mutual determination of the connected reinforcement elements have taken care of, but during installation collided with the on-site reinforcement, which is why severed or largely removed on site had to be. Thus, the device can be without Adjustments are built in, without the Quality and stability of the position of the reinforcement elements is affected.

Especially with regard to the definition of the shear bars it is essential to this due to its angled The course also against twisting, for example to secure the axis corresponding to the oblique course, because such a rotary motion becomes a big one Change in position of the shear bar and its pivoting from the vertical orientation opposite would lead to the insulating body.

The installation modules are together with the reinforcement elements pushed axially into the insulator and fixed there. The insertion does not lead only for the generally very long tension rods and the pressure rods, which provide pressure plates are, whose diameter is much larger than that Pressure rod cross-section is to a threading problem, also - and above all - the shear bars can be due to their at least two angled course only with difficulty in corresponding insulating body recesses deploy.

Proceeding from this, the present invention is the Task based, the component for thermal insulation is not only with regard to its transport and storage expenses, but also in terms of its mounting and Improve manageability.

This object is achieved in that the insulating body for inserting the at least one Shear force rod equipped built-in module divided is, the parting plane is the cutouts for the Installation module crosses, and that the installation module vertically into the recess of one half of the insulator can be used and fixed there.

This has the advantage that the insulating body with different reinforcement elements or Built-in modules can be fitted, whereby the reinforcement elements, especially the printing plates, even can have larger dimensions than the associated ones Cutouts in the insulating body. By the invention Split the insulator and insert it vertically you get not only the desired from the built-in elements provided location fixation, but in addition, a simplification when assembling the components according to the invention for thermal insulation.

Characterized in that the reinforcement elements in the vertical direction inserted in the corresponding recesses in the insulating body the reinforcement elements are also on the Construction site secured against horizontal movement and do not have to be horizontal first and mostly only one-way locking means be provided. However, the vertical Insert the built-in modules in the insulating body their definition, for example, by suitable locking means be ensured. The built-in modules can be used for this have guides running in the direction of insertion, those provided with corresponding ones on the insulating body Guides work together. Are best, however the built-in modules are positively anchored in the insulating body.

In this context, it is particularly advantageous if the insulating body has at least one firmly connected to it Has ledge made of a harder material than the insulator, and if the built-in modules on the bar especially by locking are fixed. While the material of the built-in modules expediently also harder than the material of the Insulator should be formed, the Correspond to the materials of the installation modules and the strip, in order to achieve an optimal fixation in particular to achieve mutual positive locking. The bar can expediently profiled as a U-shape Be formed rail and the one insulating body half both on the side and on its lower or Enclose top. The bar or rail can also be connected in one piece to the built-in module, for example on one U-leg while the other U-leg, in particular by latching on the built-in module is definable.

By combining the built-in module and the U-shaped one Rail can fix the position of the Improve the shear force, on the other hand stabilized but the installation module for the entire component Thermal insulation by placing the U-rail on both legs defines and at the same time at least one insulating body half embraces. This is the first time that an in stable component for thermal insulation posed by precisely positionable and reinforcement elements that can be securely fixed against each other distinguished and here completely without already at Manufacturer to perform welded joints, resulting in a further reduction in assembly and Warehousing expenses leads.

The installation module is expediently used in the present case Case not only for fixing the shear bars. Especially it is advantageous if also on the side of the component as close as possible to the shear bar Pressure elements integrated into the built-in module so that the last reason for welding a distribution bar becomes obsolete, rather both Reinforcement elements as close as possible and yet in fixed fixed distance from each other can. This combination of compression and shear bars in a built-in module not only leads to a simplified one simultaneous installation of both reinforcement elements, but primarily serves that both reinforcement elements perform their associated function safely can. The pressure element can also advantageously be used with a profile along the in the insulating body extending pressure rod and be provided with a appropriate profiling of the built-in element Cooperate to improve mutual determination.

The main advantages of the invention can be already achieve when the built-in modules reinforcement element assigned to them at least to the Encompass peripheral areas of the insulating body; however is it is particularly advantageous if the grasping throughout Course of the reinforcement element through the insulating body through, but at least in one essential Section of this is done. Because the larger the contact areas the built-in modules on the insulating body, the larger is also the quality of the fixation.

It is particularly recommended here if the built-in modules have an asymmetrical outer shape, so on the one hand to provide an installation aid, by the correct orientation of the reinforcement element is ensured relative to the insulating body, on the other this also allows the form fit in particular in the axial direction and thus the fixation of the Increase installation modules in the insulating body. Conveniently are the dimensions of the built-in modules the end face facing the installation part is different on the dimensions of the other face. For the shear bars it is especially recommended that Training modules to be polyhedral, because of the Variety of surfaces the torsional stiffness of the Installation modules compared to the insulating body is increased.

It is particularly advantageous if the shear bars profiled at least in the area covered by the built-in module and in particular are ribbed to a mutual frictional and non-positive concern to achieve the shear force bars on the built-in modules. If the built-in modules in the shear bar profiled areas and in particular are ribbed, this can be mutual Even increase anchorage. By a suitable one Choice of both ribbing directions is not only possible an axial displacement of the shear bars, but also exclude their twisting and thereby one Achieve sweat-free yet secure position fixation.

In terms of a simple structure of the built-in modules it is particularly useful if this consists of two in particular half-shells joined together in one piece bribe, which is conveniently reaching around and Define the reinforcement element assigned to them can be locked together. Of course there are others too Types of definition possible, each essential is that fixing while jamming the reinforcement element takes place approximately under friction. Both Half-shells best have a semi-cylindrical shape for this Recess in which the reinforcement element is used.

In order to reduce the variety of variants of the insulating body, not to different reinforcement element dimensions It’s special to have to adjust advantageous if the built-in modules with different Reinforcement element dimensions the same Have outer shape, for example in the above described half-shells with semi-cylindrical Cutouts only their cylinder diameter will be changed. As a result, an insulating body is sufficient for different stress cases.

Finally, the variety of options for Reduce the insulating body to be made available by that the number of cutouts is as large as possible Load case is adapted, then by Provision of dummy modules that have the outer shape of the Installation modules correspond, all not with a reinforcement element cutouts to be equipped with the Blind modules can be provided. This will the recesses against ingress of in-situ concrete protected and thus the manufacturing unintentionally Cold spots avoided.

A component 1 according to the invention is shown in FIG Thermal insulation shown in a schematic side view. This component consists of an insulating body 2 and from perpendicular to its longitudinal extent extending reinforcement elements 3 in the form of in the upper Area of the insulating body arranged tension rods 4, arranged in the lower region of the insulating body Push rods 5 and two are in the middle of the insulating body crossing, each the traction zone of one Component with the compressive force zone of the other component connecting shear bars 61 and 62 (in Figure 1 is only one member is shown for each type of reinforcement, while the other rods with the ones shown Bars are aligned).

The reinforcement elements extending through the insulating body 2 3 are each by built-in modules 7, 8 or 9 performed opposite the reinforcement elements fix the insulator. For this purpose, the insulating body Cutouts adapted to the external shape of the built-in modules on so that the insulating body is flat the recess side walls abut the built-in modules.

While the tension and compression bars the insulating body 2 exactly penetrate vertically, are the angled ones Shear bars 61 and 62 with their oblique, extending from top to bottom in the insulating body arranged and pass through the built-in module 8, the shear bars in this oblique, grips not angled course. To the built-in module 8 in the recess adapted to its outer shape of the insulating body is the insulating body 2 divided in the horizontal direction, i.e. in an upper, the tension rods 4 together with the installation module 7 Half 21 and in a lower one, the pressure rods in addition to the installation module 9 and the installation module 8 for the transverse force rods receiving half 22. The parting plane 23 runs straight at the level of the top edge of the module 8, whose side faces in the vertical direction run slightly inclined inwards and so the positive Ease of insertion. At the top of the Insulating body 2 is a U-shaped strip 24 is provided to define the two halves of the insulating body 21 and 22 serves by the two vertical U-leg down over the second half of the insulator 22 project. This U-bar is used in particular to the built-in module 7 in the Jamming position, which is done via locking lugs 17, the one at the end of the built-in module 7 with the smaller one Outside diameters are provided and from the insulating body penetrating a groin recess and protrude under the U-bar.

The same applies to the installation module 9 of the pressure rods: A U-shaped bar 25 is also provided here, which engages around the insulating body 2 on its underside and serves to fix the built-in module 9 by made of a material corresponding to the built-in module is harder than the insulating material of the insulating body trained and therefore to fix the position is preferred. The built-in module 9 also has its thinner end locking lugs 19 on the U-bar after the crossing of a groin recess from the outside embrace positively. Finally, is on the opposite A stop 29 on the side of the installation module 9 provided that the axial insertion of the module or the pressure rod defined therein. In in the same way is a stop 27 on the installation module 7 intended.

In Figure 2, the built-in module 8 with the two shear bars 61 and 62 shown separately. Here will once again the outer shape clearly, the position fixation the shear bars in particular against their mutual Panning shows. Not only that sloping side surfaces, but also the angled bottom surface of the built-in module 8 suitable to prevent further contact areas provides a pivoting. The straight one Course of the top of the module 8 is recommended to simplify the recess in the insulating body 2, because this means that the upper half 21 does not have its own recess must have.

That the two shear bars 61 and 62 in the direction of Longitudinal extension of the insulating body arranged one behind the other can be seen in particular from FIG. 3, which the built-in module 8 together with the two Shear bars 61 and 62 shows in front view. The Side surfaces that can be seen here run parallel to each other, but can be used to simplify insertion of the module in the recess in the insulating body also slightly inclined towards the inside be.

Finally, FIG. 4 shows the top view of the built-in module 8 and shows that the built-in module is relative formed asymmetrically to the longitudinal axis of the insulating body is, which is a mirror-inverted onset Prevent the built-in module and shear bars leaves. This is particularly recommended because the concrete cover on the side of the cantilever External component larger than on the side of an internal one False ceiling must be so that adapted to it the transverse force rod 62 somewhat in its lower course is positioned higher than the transverse force rod 61.

5 shows an alternative embodiment of a Component 31 shown that a built-in module 32 for Has shear bars 33, including the associated insulating body 34 is made in two parts and one upper insulator half 35 and a lower insulator half 36 exists. Between the two halves the built-in module 32 is provided, which the lateral force rod in its oblique course within the area of the insulating body.

The lower insulating body half 36 borders with it Top of the built-in module 32 while it is on its underside by a U-shaped profile 37 is surrounded. This bar is about rest connections 38, 39 connected to the built-in module 32 at the same time Fixing the lower half of the insulating body 36.

The component 41 shown in FIG. 6 corresponds to FIG most of the component 31 from Figure 5; of the the only difference is that the built-in module 42 in one piece with the lower U-profile Bar 47 is connected, in the area of a U-leg, while the other U-leg over one locking connection 48 corresponding to locking connection 38 can be fixed on the installation module 42. The one-piece connection in the area 49 is designed to be pivotable, so that the U-rail around the not shown in Figure 6 lower half of the insulator and then with the built-in module can be locked.

The respective upper insulating body halves 35, 45 from the Figures 5 and 6 limit with their oblique course of the shear bars adapted to the built-in module 32 and 42 respectively while on their top are also surrounded by a U-rail.

As far as the built-in module is concerned, it can have recesses 40, 50 may be provided, on the one hand for weight reduction and on the other hand to make one Form-fit with the adjacent insulating body halves can serve.

FIG. 7 shows an enlarged section of the installation module 32 from Figure 5 and leaves its two-shell design recognize: Here are two half shells 32a, 32b over a bending area 32c in one piece and against each other pivotally connected to each other, the Half shells in the swivel range are generally cylindrical Cutout for receiving the transverse force rod 33 exhibit. The two half-shells are via a snap connection 32d definable against each other.

Both the built-in module 32 and the transverse force rod 33 are profiled in the areas that touch each other executed so that a better friction between two components is generated, which fixes the position of the shear force rod in the module still increased.

In summary, the advantage of the present invention lies in that on the welding of distributor bars can be dispensed with by the inventive Installation modules the quality of the position fixation of the individual reinforcement elements increased drastically becomes. This results in a simplified assembly and Manageability of building element and reinforcement elements, which ultimately leads to a drastic reduction of transport and storage expenses.
