Abstract

Substructure for a construction that is self-supporting without the substructure and use of the substructure. The invention relates to a substructure for a construction that is self-supporting without the substructure, which construction has at least one carrying component accommodating at least one force, wherein the substructure can be arranged relative to the construction in such a way that it is located at least partly in direct proximity to the at least one carrying component, accommodating at least one force, of the construction. The invention also relates to the use of the substructure as an underpinning structure or as a reinforcement for the construction.

Description

The invention relates to a system consisting of a substructure and a structure, wherein the Unterfangkonstraktion is designed and determined to secure the self-supporting structure without the Unterfangkonstruktion, and wherein the structure has at least one force-receiving support component.

Structures of whatever kind have in some form Ttagkomponenten, such as walls, beams, roof beams, struts, scaffolding or a supporting structure in general, which give the structure its static strength and its static load capacity and the building to a self-supporting structure do. Under a self-supporting structure so a construction is understood that is sustainable because of its supporting components having construction in itself. The structures are designed such that at least one support component of the structure can accommodate at least one force, generally several forces, be it weight, pressure or tensile forces

Buildings can be protected, such as houses and buildings, by an outer lining and / or a roof at least partially against the weather. However, there are also structures such as antenna systems, mast systems or electricity pylons, for example, have a grid-shaped support structure, which is exposed directly to the weather.

Regardless of whether the building is a closed structure, for example in the form of a building, or an open structure, for example in the form of a power pole having a latticed support structure, these can, in particular under the influence of the weather, especially if they are exposed to them for years, theirs Wearing properties, in particular their carrying capacity, as far as the influence of the forces acting on them change, usually reduce. For example, under the influence of cold, heat, moisture, snow and ice, it has repeatedly collapsed into the roofs of buildings, in particular halls, causing damage to people. Furthermore, under the influence of cold, heat, moisture, snow, ice and winds, inter alia, fractures of grid-like supporting constructions, for example electricity pylons, have occurred, which means that the supply of electricity to part of the population was sometimes interrupted for days.

Out DE 198 03 854 A1 a method and a device for raising masts is known in which or in the interior of the mast to be increased, a mounting device is constructed, on which a mast top is held on zugseil and lifted and then a mast base is replaced.

The invention has for its object to provide a system of Unterfangkonstruktion and structure of the type mentioned in such a way that the underpinning is not directly connected to the support component of the structure for the introduction of forces and yet at least some assurance for the structure results.

The object is achieved with the features of claim 1. Further developments are specified in the dependent of claim 1 claims.

According to the invention, in the above-mentioned system consisting of a substructure and a structure, the substructure is arranged relative to the structure such that it is at least partially in the immediate vicinity of the at least one at least one force-receiving support component of the structure.

According to the invention it is therefore proposed to provide on a self-supporting structure a Untetfangkonstruktion to hedge at least one, for example, a weight, tensile or compressive force, receiving support component of a building. The building may be a building, a mast or the like, but also a roof construction, a scaffold or a supporting structure in general. The support component of the structure may be, for example, individual beams, struts or the like. The substructure is, as already mentioned, not necessary to give the structure in itself its carrying capacity or load capacity, but serves only to secure the building.

The invention provides a Unterfangkonstruktion. An operation is understood to mean that the underpinning structure is not directly connected to or in contact with at least one load-bearing force-bearing component or forces, but that the underpinning structure or construction portion of the underpinning structure is defined in a particular one selected distance from the at least one support component of the structure is located.

The distance is chosen such that, for example, seasonal and / or weather-related Matetialdehnungen and / or contractions and vibrations of the supporting component of the structure in an expected, usual tolerance range does not lead to a contact of the substructure or the construction section with the support component of the building. It thus becomes clear that the distance between the construction section or the substructure and the supporting component can be adjusted depending on the type of structure and the material of the supporting component and depending on the forces and influences normally acting on the supporting component, if necessary in addition a security default is selected.

The distance is further selected such that the construction portion or the Unterfangkonstruktion in case of failure or static yielding the the force-absorbing Tragkomponeute of the structure can support the support component at least for a certain time. Preferably, the distance between the construction section or the substructure and the supporting component of the structure is chosen as low as possible.

If a substructure is mentioned below in connection with the invention, this is to be understood as a substructure according to the above explanations.

According to a variant of the invention, the substructure has at least one construction section. The substructure or the construction section in turn comprises at least one construction element, which may be, for example, a rod, a tube, an angle profile, a cable, a cable net and / or a connecting element for at least two such construction elements. The Untetkonstruktion does not necessarily have several construction sections, but may also have only one construction section. There is also the possibility that the construction section is or embodies the substructure.

As suitable for a substructure, a space framework has, which usually comprises steel formed tubes or rods, which may be tapered at their ends and with spherical connecting elements together to larger, especially static constructions, can be connected. Such space frameworks are known by the company MERO TSK International GmbH & Co. KG located in Würzburg. Incidentally, the spherical connecting element is also referred to as a so-called mero node, which has a plurality of sections for fastening tubes or rods or for connecting tubes and / or rods to one another.

The substructure is, for example, for a roof of a building, e.g. a hall, provided, wherein the substructure or a construction section of the substructure can extend substantially parallel to the roof. If the building is, for example, a hall with a flat roof, then the construction section or the substructure runs substantially horizontally parallel to the flat roof, possibly also adapted to the roof pitch. However, the construction section or the substructure can also be arcuate or adapted to the shape to be secured to the support component to be secured.

The substructure or the construction section of the substructure is located at least partially inside or below the structure and / or inside or below or adjacent to the at least one force-bearing structural component of the structure. For example, the construction section or the substructure may be located below a roof structure of a building or within a ceiling or a supporting structure of a building.

Depending on the structural conditions and the requirements of the building or the use of the building, the construction section or the substructure, for example, in a building at least partially extend through a wall of the building, if this or these are not stored within the building can.

The construction section or the substructure can be arranged according to a variant of the invention at least on a support, wherein the support can be located inside or outside the building. If the support is located outside the building, the substructure or the construction section of the substructure, for example in the case of a building, extends at least partially through a wall of the building. Should it allow the structural conditions of the building and the use of the structure, the substructure or the construction section of the substructure may at least partially on a Be part of the structure or be stored on an annex to the building. For example, the construction section or the substructure may be mounted on a part of the wall of a building or on an attachment to the wall of the building or on a foundation of the building.

In addition, the substructure may have at least one bracing, which is preferably located outside the structure and is usually accomplished with a rope or pipes.

According to a wide variant of the invention, the substructure is provided for a bridge and, in particular for this purpose, may be at least partially arcuate.

According to one embodiment of the invention, the substructure is associated with a measuring device for mediating the distance between the at least one force-receiving support component of the structure and the substructure or the construction section of the substructure. Such a measuring device comprises, for example, a plurality of distance sensors, which can be arranged, for example, on the bottom bracket and detect measured values continuously or at specific discrete points in time, from which the distance between the supporting component of the building and the substructure can be determined. If the distance between the at least one force-receiving support component of the structure and the substructure reaches or falls below a preferably predefinable limit value, an alarm can be triggered based on the measured value or values of the measuring device. This makes it possible, on the one hand, to register changes in the carrying properties of at least one structural component of the structure relatively quickly and, on the other hand, to initiate measures such as evacuation of a building in order to avoid personal injury, for example by a collapsing roof of the structure.

The substructure is provided, for example, for a construction comprising a latticed structure and / or struts comprising supporting structure. Such a structure is, for example, a mast, e.g. a power pole. Such a mast may have a tower-like mast body and / or at least one, but usually a plurality of support arms, which are arranged on the mast body. The substructure is arranged in the case of such a mast at least partially in the mast body and / or in a support arm of the mast body.

According to a variant of the invention, the substructure may be at least partially disposed on a foundation of the structure. In the case of the mast, for example, the foundation of the mast can be used to order the substructure on it. In addition, it may be provided that the substructure of the grid-like structure of the supporting structure of the mast at least largely follows. However, the substructure does not necessarily have to be arranged on the foundation of the structure or of the mast.

According to one embodiment of the invention, the substructure is preferably designed such that it can be easily retrofitted in or on a building. The retrofitting of the substructure usually requires no use of heavy lifting equipment or protruding additional foundations. In addition, results from the substructure, especially if this is designed as a space framework, is no change in the external appearance and no use EinmaßnÄnkung of the building.

As already stated, the substructures described above are used to support at least one at least one force-receiving support component of a structure in case of static failure of the force-bearing support component of the building. The substructure is therefore a purely auxiliary construction for securing, if it is a static failure a structural component of a structure, for example, to the failure of a roof comes.

a side view of a bridge with an underlying substructure.

In FIG. 1 is shown in a simplified, partially sectioned view the view of a hall 1, which in the case of the present embodiment, four, the hall framing, supporting walls, of which two side walls 2 of the hall 1 in a sectional view in the FIG. 1 are shown. On the side walls 2 are roof racks or roof trusses, which extend between the side walls 2, arranged, of which a roof rack 3 in FIG. 1 is shown. The side walls 2 are walls in the case of the present embodiment.

The roof beams 3 of the hall 1 are in the case of the present embodiment, wooden beams which extend across the hall 1. The wooden beams can be both solid wood beams and beams made of glued wood. However, there is also the possibility of the roof rack 3 made of steel or other suitable, sustainable materials. On the roof supports 3, a covering 4 is arranged in the case of the present embodiment, which is mounted on the roof beams 3. The roof beams 3 are supporting components of a roofing-supporting day or roof structures of the hall 1. The roof beams 3 take as supporting components of the hall 1 each part of the weight of the roofing 4 and more, in particular acting on the roofing 4 Forces, be it compressive or tensile forces or the like., On.

The roof structure of the hall 1, in particular the roof rack 3 of the hall 1, are always particularly heavily loaded if the weight of the roofing 4 other loads act on this, which may be the case, for example, in winter, when snow and ice masses located on the covering 4. Due to aging phenomena and possibly unwanted influences such as moisture penetrating through the roofing 4 on the roof rack 3, it may happen that individual roof rack 3 or all roof rack 3 change their carrying properties and permanently can not withstand the forces acting on them, so that there is a risk of collapse of the roof, especially in the case of heavy loads on the roof structure, which may be the case in the winter due to snow and ice masses.

It is therefore proposed, as a security measure, especially at times to which large loads on the roof beams 3, in the case of the present embodiment below the roof structure of the hall 1 or below the forces receiving support components in the form of roof rack 3 at least one substructure 5 such be arranged under at least one roof rack 3 that at least one construction section 6 of the substructure 5 is at least partially in the immediate vicinity of a force-receiving support component in the form of a roof rack 3. The substructure may also extend over the entire extent of the roof structure of the hall 1. It exists however also the possibility to assign such a substructure only individual roof beams 3, which are exposed to a special load, or the substructure differently than in FIG. 1 represented perpendicular or transverse in a different angle from 90 ° to the course of the roof rack 3 to arrange. In the case of in FIG. 1 In the embodiment shown, each roof carrier 3 is assigned a substructure 5 with a construction section 6.

In the case of in FIG. 1 the embodiment shown, the construction section 6 of the substructure 5 on supports 7, 8 of the substructure 5 outside the hall 1 is arranged. In order to accomplish this, the side walls 2 of the hall 1 each have an opening 9 below a roof rack 3. Preferably, however, an opening 9 is not as in FIG FIG. 1 shown directly below a roof rack 3 available, but arranged laterally offset to a roof rack 3 in order not to impart the sustainability of the side wall 2. In this case, the construction section 6 is adapted accordingly, ie it has at least one transverse component to guide the construction section 6 laterally away from a roof carrier 3 and through the side wall of the roof carrier 3 arranged in the opening.

The opening 9 is designed in such a way that the roof carrier 3 associated construction section 6, which in the case of the present embodiment has a bar-shaped or parallelepiped-shaped outer structure, can be guided through the opening 9. As already mentioned, the construction section 6 is supported outside the hall 1 on supports 7 and 8.

In FIG. 2 a variant of a substructure 5 is shown in a schematic plan view of the Hall 1 with removed roofing 4, in which the substructure 5 has construction sections 6 which extend across the Hall 1 and the openings in the side walls 2 of the hall 1, not shown are guided, which laterally offset below the Roof rack 3 are located. The construction sections 6 are mounted outside the hall 1 on supports 7. The substructure 5 in this case has one or more construction sections which are arranged transversely to the construction sections 6 and which are located at least partially in the immediate vicinity below the roof beams 3.

In the case of the present embodiment, a construction section 6 is designed as a space framework and accordingly has bars 21 and / or tubes and connecting elements 22 for connecting the bars and / or tubes to one another. The connecting elements are usually the so-called mero nodes 22, as used for example by the company MERO-TSK International GmbH & Co. KG for the construction of space frameworks. The support 8 is designed in the case of the present embodiment as a space frame. Alternatively, however, the support can also, as shown by the example of the support 7, be a mast made of wood or steel or another suitable material, which can be provided, for example, with a bracing 10 for stiffening the substructure 5. The bracing 10 is usually a steel cable or a pipe system, which is fastened in the ground accordingly and allows a corresponding bracing of the substructure 5,

The openings 9 in the side walls 2 of the hall 1 are otherwise in in FIG. 1 and FIG. 2 not shown manner after carrying out the construction section 6 and 36 respectively sealed, which can be done for example by walling, by a filled with an insulation interior and exterior trim or otherwise in a suitable manner.

Again FIG. 1 can be removed, touches the substructure 5, in particular the construction section 6, the roof of the hall 1 bearing support components in the form of the roof rack 3 and thus unfolds no support function for the hall 1 itself, in which it is a self-supporting Building acts. The substructure 5, which may also be referred to as a substructure, is an auxiliary construction and serves to secure the hall 1, in particular the securing of the roof or the roof rack 3 of the hall 1. The support structures 5 and in particular the construction sections 6 of the substructures 5 have the Task to prevent a sudden or over a period of time already suggestive static failure of the supporting function of a supporting structure such as the roof of the hall 1, that in a breakage of one or more roof rack 3, the roof collapses and possibly harms people. Should it actually come to a failure of one or more roof rack 3 of the hall 1, a respective construction section 6 of a substructure 5 catches the failing or breaking roof rack 3 and prevents or retards the collapse of the roof of the hall 1 at least over a certain period of time that persons who may be in Hall 1 may leave Hall 1 before the collapse of Hall 1. The substructures 5 are therefore used in case of failure of the roof structure of the hall 1 to support the roof structure, in particular the roof rack 3. The construction sections 6 are arranged in the immediate vicinity of the roof rack 3, wherein the construction sections 6 are located at a defined distance below the roof rack 3 ,

Also in FIG. 2 shown variant of the substructure 5 unfolds the effect described above.

In the 3 to 5 is compared to the in FIG. 1 illustrated embodiment, a variant of a substructure 5 for the hall 1 shown. The substructure 5 of FIG. 3 shows how the in FIG. 1 extending substantially parallel to the roof beams 3, across the hall 1 extending construction sections 6, which in the case of in FIG. 3 However, the embodiment shown are not arranged below a roof rack 3, but, in particular the 4 and 5 can be removed, run between or next to the roof beams 3. In FIG. 3 is one between two roof beams 3 extending construction section 6 indicated only schematically. The construction section 6 extends, as in FIG. 1 , on both sides in each case by an opening, not shown, or an opening in a side wall 2. The opening is located between two roof beams 3 and is preferably secured with a fall. Outside the hall, the construction section 6 is again supported on supports 8 and 7.

As in particular the 4 and 5 can be taken, showing non-exhaustive examples of possible construction structures of the construction sections 6, the Bauababnitte 6 via trusses 32 and load cross members 32 are connected, which are arranged below a roof rack 3 at a certain distance from the roof rack 3. In the 4 and 5 each connects a traverse. 32 two Konstruktlonsabschnitte 6. A traverse 32 but can also connect several construction sections 6 or all construction sections 6 together. A traverse can run parallel to a roof rack 3 or transversely to a roof rack 3. It is essential that a traverse when yielding a roof rack 3 intercept the roof rack 3 and can support at least for a certain time.

The variant of a substructure according to 3 to 5 offers the advantage that there is a loss of space inside the hall due to the substructure, so that there is no restriction of the possibilities of use of the hall.

This in FIG. 6 embodiment shown differs from that in FIG. 1 shown embodiment in that the construction section 6 of a substructure 5 is not supported on supports which are arranged outside the hall 1.

In the case of in FIG. 6 As shown, the construction section 6 of the substructure 5 is supported on one side on a support 7, which, as already mentioned, in the case of the present embodiment located within Hall 1. On the other side of the in FIG. 6 In the embodiment shown, the construction section 6 of the substructure 5 is mounted on a part of the hall 1 in the case of the present exemplary embodiment on a bracket 11 of the side wall 2 of the hall 1. As before for the in FIG. 1 described embodiment, each roof rack 3, a substructure 5 may be associated with a construction section 6, as shown in FIG. 6 shown on a console 11 and supports 7 can be stored. However, the construction section 6 may also extend over the entire hall 1 or it may be provided in different areas of the hall 1 design sections 6. As in the case of in FIG. 1 the embodiment shown is also the construction section 6 of in FIG. 6 shown embodiment implemented as a space frame.

Incidentally, in particular, as far as the storage of a construction section 6, any mixed forms between the in the 1 to 6 shown embodiments possible. Thus, the Koansttuktionsbschnitte 6 and the substructure can be stored for example only on consoles 11 or only on supports 7 or 8 inside or outside of the hall 1. Likewise, the storage of construction sections, which run between roof beams, on brackets between the roof beams is possible, the construction sections are connected via traverse.

In the case of in FIG. 6 In the embodiment shown, the substructures 5 are additionally assigned a measuring device for automatically determining the distance between a roof carrier 3 of the hall 1 and a construction section 6 of a substructure 5. In this case, the distance to the construction section 6 assigned to it need not be determined for each roof rack 3. In the case of the present exemplary embodiment, the measuring device comprises measuring sensors 12, two of which are in FIG. 6 are shown and cooperate with an evaluation unit 13. The sensors 12 may be mechanical or electronic Probe with eg attached to the sensors strain gauges act, for example, the sensors can cause the closing of an electrical switch to trigger an alarm signal. The probes may be non-contact probes, such as ultrasonic sensors, or touch probes. For example, a sensor may touch the roof beam 3 and the structural section 6 and be provided with strain gauges. The probes 12 are in FIG. 6 not shown way with the Auswetteeinheit 13, which may be a computing device, for example via cable connected. However, the measured values of the measuring sensors 12 can also be transmitted wirelessly to the Auswetreeinheit 13 via free electromagnetic waves. If the evaluation unit 13 determines that the distance between a roof rack 3 and a construction section 6 of a substructure 5 reaches or falls below a preferably predeterminable limit value, this may cause the triggering of an alarm, for example an alarm signal in the form of an optical or acoustic alarm signal. The alarm signal has a warning function and indicates, for example, people in Hall 1 to leave the hall as quickly as possible. An alarm signal can also be routed automatically to the police, the fire brigade or other rescue services.

Another embodiment in which a substructure is used as a subframe is shown in FIG FIG. 7 for a bridge 14 across a river 15. Below the bridge 14, a substructure 16 between two slopes 17 is arranged. The substructure 16 can also be placed on a in FIG. 7 indicated foundation 30, for example, a dam 31 may be arranged. The substructure 16 is formed in the case of the present embodiment of a space frame 18 and ropes 19 and has a construction portion 20 which is disposed approximately in the middle of the bridge 14 below the bridge 14 at a certain, defined selected distance from the bridge 14 , The substructure 16 is in the case of in FIG. 7 embodiment shown executed substantially arcuate and in turn is used in the case a failure of the bridge 14, be it by an overload acting on the bridge 14, or as a result of aging of the bridge 14 to support these at least for a certain period of time, preferably all persons and vehicles that at the time of failure on the Found bridge that left the bridge before collapsing.

The support structure 16 can, moreover, in a comparable manner to that in connection with FIG. 6 described embodiment, a measuring device for determining the distance between the substructure 16 and the structural section 20 of the substructure 16 and the bridge 14 have. In the in the 3 to 5 shown embodiment, at least one traverse at least one sensor can be assigned.

The substructure has been described above using the example of a space framework, which has, inter alia, tubes, rods and / or connection nodes. However, the substructure does not necessarily have to be realized in the form of a space frame, but may also be a construction of a rope, for example using cable nets, or other construction using suitable materials. Since the substructure has no supporting function, it can be made relatively compact and is suitable for retrofitting into an existing structure.

Furthermore, the substructure may be provided for structures other than the roof of a building or a bridge.

Components which at least substantially coincide in terms of their function and design in the exemplary embodiments shown are otherwise provided with the same reference numerals.
