Description

Building

The present invention relates to a building, comprising a first building part, a second building part movable relative to this, and at least two between the two

Structural bearings acting on structural parts, with a first

Structural bearings are suitable for transferring vertical loads and a second structural bearing is designed as a horizontal force bearing that is unsuitable for transferring vertical loads and is one-axis or two-axis fixed in the horizontal direction.

Bridges in particular come into consideration as structures in the context of the present invention. The first structural part can be used as an abutment (and thus as part of the substructure of the bridge), the second structural part can

be designed, for example, as a superstructure of the bridge. On the basis of DIN EN 1337-8: 2008-01 (D), horizontal force bearings are to be understood as guide bearings and retaining structures. A guide bearing is therefore defined as "a bearing that offers resistance only in one horizontal direction, allows twisting and does not transmit any vertical forces". Only such guide bearings in the above sense are a horizontal one

Direction of uniaxial fixed horizontal force bearing, if the bearing limits movements along both half-directions of a horizontal axis. A retaining structure, which is defined as a bearing, which "prevents movements in the horizontal plane, allows twisting and does not transmit any vertical forces", corresponds to the above-mentioned horizontal force bearing that is unsuitable for the transmission of vertical loads and is biaxially fixed in the horizontal direction.

Horizontal force bearings are known in various embodiments from the prior art. DIN EN 1337-8: 2008-01 (D) discloses several typical uniaxial horizontal force bearings (guide bearings), as they are in a structure of the initially described type can be used. One of the guide bearings described in DIN EN 1337-8: 2008-01 (D), Figure 1 comprises two anchor structures, whereby these are typically firmly connected to one of the two structural parts by means of suitable fastening means. The two

Anchor structures interlock in a kind of tongue and groove configuration in such a way that movements along a horizontal axis are enabled, but are prevented in the second horizontal axis perpendicular to this. Typically, the two anchor structures are not in direct contact with one another, but rather via sliding elements arranged between the anchor structures, the sliding elements mostly consisting of materials that are particularly suitable for forming low-friction sliding pairs.

The present invention is based on the object of providing a structure of the type described at the outset which, compared to the prior art, is more cost-effective to build, maintain and ideally also during the

Maintenance phase can be used without restrictions, and is also more durable. Particular attention is paid to the simplest and least possible

error-prone connection of the horizontal force bearing to the two structural parts.

This task is solved by a structure of the type described above, in which the

Horizontal force bearing comprises a first and a second anchor structure, the first anchor structure being fixedly connected to the first structural part via first anchor elements arranged on it, and the second anchor structure fixed to the second structural part via second anchor elements arranged on it

connected is. At least one first guide element with a first sliding surface is with the first anchor structure releasably connected, and at least one second guide element with a second sliding surface opposite the first sliding surface is releasably connected to the second anchor structure, wherein the first and the second

Sliding surface are in contact with each other and each other in the vertical direction forming at least one

Overlap sliding contact zone. The at least one

The sliding contact zone overlaps the first anchor structure in a horizontal projection. Furthermore, the second includes

Anchor structure Support elements on which the associated at least one second guide element is supported in a form-fitting manner opposite its second sliding surface with horizontal force transmission. The second anchor structure and / or the at least one second guide element overlaps the first structural part in the horizontal projection.

Through the synergistic combination of the above

specified for the structure according to the invention

Characteristic features can be a building with an unusually flat surface compared to the state of the art

Horizontal force bearings can be realized. Due to the flat

The geometry of the horizontal force bearing ensures that the lever arms of the horizontal forces to be transmitted turn out to be extremely small and thus only small moments between the respective anchor structure and the corresponding one

Part of the building. Compared to the state of the art, in which horizontal force bearings are designed to be less flat and thus significantly higher moments act between the anchor structures and the building parts, anchor structures,

Anchor elements and structural parts of a structure according to the invention are less heavily loaded in this way. These

lower stress is reflected in a longer service life of the structure and can also be passed through

Translate material reduction into lower manufacturing costs. A fixed connection between the anchor structure and structural part via anchor elements in the above sense is a connection which, within the framework of the intended and proper use, does not allow translational or rotational movements in relation to a technically meaningful order of magnitude, regardless of whether the connection is detachable or undetachable is. Anchor elements are defined as components that can transmit tensile and shear forces. Said anchor elements can be designed as headed bolts, for example.

At this point it should be noted that, for reasons of readability, in some places it has been dispensed with in the case of components that were assigned a minimum number in the context of the initial mention, this reference to the said minimum number also in all subsequent mentions. Of course, the minimum number of components specified when it is first mentioned applies in the

same dimensions for all subsequent mentions of the same, even if the explicit reference is omitted.

According to a first preferred development of the invention, the structure is characterized in that the first

Part of the building in the horizontal projection of the

Sliding contact zone extends into it. Since a particularly flat horizontal force bearing can be realized in this way, those mentioned above and accompanying it apply

Benefits to a very special degree.

Another preferred development of the structure according to the invention is characterized in that at least one of the guide elements can be exchanged with an unchanged vertical distance between the two anchor structures.

This vertical distance between the two anchor structures is during normal operation of the structure a largely constant size. This distance is defined by the design of the first structural support, which is suitable for transferring vertical loads, and the two structural parts at a defined vertical distance

to each other. By having at least one of the

Guide elements is interchangeable with an unchanged vertical distance between the two anchor structures, it is thus expressed that at least one of the guide elements

can be exchanged without having to lift a structural part (and thus having to change the vertical distance between the two anchor structures). Thus, the first structural store can also be used during the

Exchange process of the guide elements of the

Horizontal force bearing is intended to transfer loads in the vertical direction. In this way one becomes in the course of

Maintenance work enables replacement of the guide elements with minimal effort. By eliminating the

Necessity of lifting a structural part can on the one hand in the course of replacing the guide elements

The use of heavy equipment required for lifting is dispensed with and, on the other hand, the structure can even be used almost without restriction during the maintenance phase. If the building according to the invention is, for example, a

Bridge, the bridge can therefore possibly even be used by traffic while the guide elements are being replaced. The costs of maintenance and the associated restriction on the use of the structure are therefore only very low.

According to another preferred development of the invention, the sliding surface is at least one of the guide elements by surface treatment, in particular by hardening

and / or polishing, particularly suitable for a low-friction pairing with the sliding surface of the

to form corresponding, adjacent guide element. The low-friction sliding pairing reduces the friction-related wear of the guide elements, which has an advantageous effect on the longevity of the component and on maintenance costs.

The same effect can be achieved if, as an alternative to or in combination with the further development of the invention just described, at least one of the guide elements is one

Sliding element and a sliding element carrier, wherein a surface of the sliding element is the sliding surface of the

forms at least one guide element, and wherein the sliding element is made in particular of PTFE, UHMWPE or another equally suitable material. PTFE (polytetrafluoroethylene) and UHMWPE (ultra-high-molecular-weight polyethylene) are typical sliding element materials used in the prior art.

In another preferred development, the structure according to the invention is characterized in that at least one of the sliding elements can be exchanged with the vertical spacing of the two anchor structures from one another unchanged. In other words (as already explained above in connection with the guide elements) at least one of the

Sliding elements can be replaced without this being a

Structural part must be lifted. The one above

The advantages outlined here, which can be achieved in that guide elements can be exchanged without having to lift a structural part for this purpose, can also be achieved in that (separate) sliding elements can be exchanged in the same way. By replacing such separate sliding elements instead of guide elements, the resulting maintenance costs can also be reduced even further, since a sliding element is typically cheaper to manufacture than a guide element. A second anchor structure which is also very simple and compact with regard to the flow of force can be used

realize if, in another preferred development of the structure according to the invention, the support elements (on which the respectively assigned second guide element

positively supported) are designed as support ribs.

In another preferred development of the invention, no tie rods connecting the first anchor structure to the first structural part are provided. Alternatively or in

In combination with this, the inventive structure can be characterized in another advantageous development in that no tie rods connecting the second anchor structure to the second structural part are provided. In this context, tie rods are defined as anchor elements that have a length / diameter ratio greater than 35. Tie rods can be designed in such a way that they are predominantly suitable for transmitting tensile forces and, despite the reference to their diameter, do not necessarily have to have a circular cross section. In the case of a non-circular cross-section, under diameter is a

To understand equivalent diameter, which can be determined by adding the actual cross-sectional area

fictitious, equivalent diameter of an equal area

Circular area is assigned.

The waiver of those that are generally customary in the prior art

Tie rods for connecting an anchor structure to a building part are made possible precisely by the extraordinarily flat design of the horizontal force bearing, as this minimizes the moment to be transferred between the anchor structure and building part and therefore, under certain circumstances, there is no need for the moment

to absorb generated tensile forces via tie rods. The waiver of tie rods enables a greater degree of freedom in the Design of the structural parts and thus the entire structure (since no tie rods have to be provided), and on the other hand, it eliminates a common source of errors on construction sites, as z.

B. during concreting work to produce the tie rod receptacles in the structural part (which are usually pending before the delivery of the horizontal force bearing on the construction site), specifications are often not met exactly what time and

can result in costly rework.

The special installation or load situation of the

Owing to the horizontal force bearing, in order to achieve a sufficiently strong connection between the second anchor structure and the second structural part, however, according to another advantageous development of the invention, it can be provided that the second anchor structure is firmly connected to the second structural part by means of tie rods that engage outside the vertical projection of the first anchor structure is.

In accordance with the objective of minimizing maintenance costs and usage restrictions during maintenance, according to another preferred development, the

Invention at least one of the guide elements below

Retaining the position of the tie rods exchangeable. The fact that the position of the tie rods can be maintained during the exchange of at least one of the guide elements shows that at least one of the guide elements can be replaced without the tie rods having to be removed (and thus the position of the tie rods having to be changed).

In yet another preferred development, the support elements are designed as support ribs and the tie rods engage between two adjacent support ribs. This arrangement enables the realization of a very flat one

Horizontal force bearing with those already mentioned above Advantages related to the minimization of the transmitted moments between the anchor structure and part of the building. This construction principle can obviously also be combined with the feature already mentioned, which the

Provides interchangeability of the guide elements while maintaining the position of the tie rods (that is, without having to remove tie rods).

According to another advantageous development of the invention, the first anchor structure forms an upper anchor structure and the second anchor structure forms a lower anchor structure. If the first, upper anchor structure is to be connected to the first structural part with the aid of concrete, the above arrangement of the first anchor structure can enable the particularly simple use of the upper anchor structure as part of a permanent formwork, which depends on the other circumstances below which the structure to be erected can be extremely beneficial.

Depending on the specific situation in which the respective structure is to be erected, it can, however, alternatively also be advantageous if the first anchor structure forms a lower anchor structure and the second anchor structure forms an upper anchor structure. Because the installation position of the horizontal force bearing can thus be flexibly adapted, specific requirements of the respective structure can be taken into account individually. The particularly advantageous overall design of the structure made possible by this can reduce the construction and maintenance costs and increase the

Longevity of the building as well as enabling completely new structural designs.

An extremely flat horizontal force bearing (with the associated advantages already mentioned above) can, according to another advantageous development of the Realize the structure according to the invention when the first and second guide elements are outside the vertical projection of the first anchor structure.

It is also beneficial for the purpose of realizing a particularly flat horizontal force bearing if in one

Further development of the invention, the first anchor structure is designed as an anchor plate and / or the second anchor structure is an anchor plate and is permanently connected to it

Includes support elements. This embodiment also has the advantage that anchor plates and thus also the resulting anchor structure can be produced relatively inexpensively, which has an advantageous effect on production costs. In addition, the use of anchor plates is also very advantageous from a static point of view, since due to the relatively simple geometry of the anchor plate, the force flows occurring during the intended use

Use can be determined quickly and easily, which is advantageously reflected in low construction costs. Furthermore, the simple geometry of the anchor plate leads to clear load paths, which contributes to a robust load-bearing behavior.

The aim of providing a particularly flat

Horizontal force bearing, it also serves if, according to a further development according to the invention, the horizontal

Extension of the first anchor structure is at least 10 times greater than its vertical extension and / or if the

horizontal extension of the second anchor structure is at least 10 times greater than its vertical extension.

The simplification of the assembly or the integration of the

Horizontal force bearing in the structure, it is also beneficial if in the first anchor structure at least one first

Opening and at least one second opening is arranged in the second anchor structure, a first in each case and a second breakthrough are aligned with one another, or at least overlap one another. Through the aligned or overlapping openings during the

Installation phase of the horizontal force bearing, for example, concrete passed through and compacted in order to connect the lower anchor structure with a structural part in this way. The simple implementation of this process with the help of aligned breakthroughs helps to reduce assembly costs and simplify assembly work, which helps to avoid

Errors during this activity is beneficial.

In connection with the transport of the horizontal force bearing (e.g. to the construction site), it is also particularly advantageous if, in another development of the inventive structure, the first anchor structure has at least two first

Includes transport securing element receptacles and the second anchor structure at least two second

Includes transport securing element receptacles, a first transport securing element receptacle and a second transport securing element receptacle being aligned with one another. A transport securing element can be detachable with a first and simultaneously with a second

Transport securing element receptacles are connected (with the first and second transport securing element receptacles being aligned with one another), whereby the two anchor structures are in a position defined by the transport element

be fixed to each other, which can be advantageous during the transport and the installation phase. After the installation of the horizontal force bearing is complete, that is

To remove the transport securing element to the

to enable proper operation of the horizontal force bearing.

In addition, in view of the reduction in manufacturing costs, it can prove to be particularly advantageous if at least one of the anchor structures is made in one piece. In addition, the one-piece design eliminates the need for fasteners

Weak points and thereby enables a higher one

Fatigue resistance. Here, “in one piece” is understood to mean “not made up of several parts”.

According to a further particularly advantageous development of the inventive structure, the first anchor structure is in

Essentially rotationally symmetrical and are the at least one first and the at least one second

Guide element designed essentially in the shape of a circular arc. Especially for the implementation of a biaxial fixed

Horizontal force bearing (retaining structure) is this

Embodiment suitable in a particularly advantageous manner, since the bearing properties within the plane in which the biaxially fixed horizontal force bearing prevents movements, are thus independent of the direction.

According to a particularly preferred development are

Support elements are arranged along a circular path, the distance between two adjacent support elements defining a circular arc along the circular path which is greater than the respective circular arc of the corresponding first and second guide elements. This enables the first and second guide elements to pass through the sufficiently

spaced support members, d. H. through the existing

The space can be dismantled and reassembled through, which increases the maintenance friendliness of the structure and thus helps to minimize maintenance costs.

In an alternative but equally preferred

In a further development of the invention, the first anchor structure is essentially rectangular and the at least one first and the at least one second guide element are in the Essentially run in the form of strips. This embodiment is particularly suitable for single-axis fixed

Horizontal force bearing (guide bearing) with which relatively large movements along both half-directions are only one

horizontal axis should be enabled.

It is also beneficial to the purpose of realizing a particularly flat horizontal force bearing if the

Support elements in the horizontal projection of the

The sliding contact zone protrude, preferably at least as far as the horizontal projection of the center of gravity of the sliding contact zone, particularly preferably completely covering the horizontal projection of the sliding contact zone. In all three

In embodiments, an extremely flat horizontal force bearing can be achieved - albeit in different degrees - which has the advantages already described above.
