Description

CONSTRUCTION ELEMENT FOR CONNECTING A BAY CONSTRUCTION TO A DAS

BAY STRUCTURE SURROUNDING TRAFFIC SURFACE

FIELD OF THE INVENTION

The present invention relates to a structural element for connecting a shaft structure to a traffic area surrounding the shaft structure with a first and second

Front side, a front and a back and a bottom and a top according to the preamble of claim 1.

STATE OF THE ART

In practice, traffic areas are provided with a road surface to the driving on with cars and bicycles

allow to make parking areas for the resting traffic or to allow walking by pedestrians. For this road surface either compactable asphalt pavements or mastic asphalt are used.

Compactable asphalt pavements are bituminous mixtures of aggregates and bitumen

Binder that complies with the applicable rules and regulations. The bituminous mixture is applied to the traffic area in a hot condition and is compulsorily fed to compaction by means of compactors. Mastic asphalt, on the other hand, is a mixture of fine and coarse aggregates with bituminous aggregates

Binders, such as road bitumen gem. Önorm B3610 or polymer modified bitumen acc. Önorm B3613, which is cast in viscous form and also forms a road surface after cooling. In contrast to the above-mentioned asphalt coverings, no compaction is required when using mastic asphalt.

Below with provided with a road surface

Traffic areas are usually drains or other lines of the infrastructure in the form of pipes and cables. In order to provide access to these pipes and cables, the traffic areas are usually at irregular intervals with vertically from the road surface running down, in

Provided substantially cylindrical shape having shaft structures, which have a shaft structure, which will be discussed in more detail later and have a passable / accessible manhole cover. The manhole covers are planned according to the level of the surrounding road surface to minimize the slightest bumps when crossing the

Manhole cover to ensure.

The problem always proves in practice

Connection of the shaft structures to the surrounding traffic area, in particular to the road surface. Asphalt coatings are introduced according to the prior art directly to the shaft structure and are connected in the sequence with this via a binder such as bitumen. So far, it has not been possible to make this connection permanent and flexible for the following reasons: - Setting the shaft structure due to high, dynamic

traffic loads Settlement of the entire shaft structure due to poor ground conditions in the area of the shaft foundation

Freezing in the surrounding area of the shaft, whereby the deeply established shaft structure does not follow the lifting - cyclical vertical movements between the shaft

Surface of the road surface and the shaft structure, triggered by freezing of the roadway structure in winter and subsequent settlement in the dew period of unique subsidence of the roadway construction due

deficient compression

Road salt and chemicals present in the wastewater, which among other things destroy the mortar joints in the shaft structure

Despite appropriate dimensioning of the manhole structures, these circumstances lead to considerable road damage occurring within a few years, especially in the vicinity of manholes or manhole covers. This causes as a direct result of a high noise ("rattle") of

Manhole cover due to eccentric traffic loads or poor Versetzarbeit destruction of the upper shaft area through

Impact loads during the rollover an increased accident risk, especially for single-lane

Road users when driving over the due to the above circumstances on the road surface protruding or compared to the pavement down offset shaft decry a clod or net-shaped cracking around the Schachtdeekel a deficient snow removal by the winter service the progressive destruction of the shaft structure and the road surface

Even when using mastic asphalt, there are identical problems, as this essentially like

compacted asphalt pavement behaves.

While there are a number of common methods of remedying the above mentioned harms, the present invention aims to prevent or minimize the effects of the mentioned types of damage. Thus, both ongoing maintenance measures can be reduced and the

Lifespan of shaft structure and traffic area are increased.

A technique sometimes used, predominantly in urban areas, is that of connecting the shaft structure to the surrounding traffic area by means of additional building elements in the form of paving stones. These are usually off

Natural stone made. Although both shaft cover, as one of several, the shaft structure constituent components, as well as the components used for connection are actually part of the traffic surface itself, is for the

Purpose of the present application under traffic area that, the shaft structure or its components and the

Components understood surrounding traffic area.

The paving stones become the shaft structure

enclosing, often along a circle, together

strung, and by means of a connecting means, preferably

Paving joint mortar or Bitumenvergussmasse, interconnected and to the shaft structure on the one hand and the

Traffic surface on the other hand connected. The transitions to the traffic area, which is usually off

Road asphalt exists, or the shaft structure are however problematic for the following reasons:

For reasons of cost paving stones are produced in diced form. Nevertheless, in order to connect shaft structures of different sizes to traffic areas, the

Paving stones are made relatively small to

In this regard, to be flexible and to optimally enclose and even connect small sizes of the manhole structures. However, the smaller the paving stones, the higher the laying effort and the thinner the load-bearing layer that they themselves represent. Small stone formats also fail to reduce the relative motion between

Shaft structure and traffic area contribute, so that the damage described above only insignificantly

reduced.

In addition, paving stones generally have a polishable surface, which in turn is a risk factor, especially for single-lane vehicles

represents. Cracks within the paving stone construction also shorten their life, since the ingress and freezing of water their weathering, for example by bursting the

Paving stone construction, is accelerated. Also

Modification work is difficult because the entire paving stone construction is a relatively rigid unit

forms, so that individual paving stones are difficult to replace this.

It is therefore the object of the present invention to provide a

Component for connecting manhole structure to a

Shaft construction surrounding traffic area to realize that avoids the disadvantages mentioned and also provides improved traffic safety, simply reworked can be minimized by its longevity the required maintenance and the associated costs, as simple as possible to manufacture and build is and with the greatest possible stability directly to each other is reihbar.

It is a further object of the present invention

Provide component that easily adheres to the shape of the

can be adapted to be connected shaft component.

In addition, the invention has the object to provide an arrangement for connecting a shaft structure to a shaft structure surrounding traffic area available, which ensures a stable and weather-resistant connection, can be used for different manhole structures and can be produced by the application of optimized methods.

A further object of the present invention is to provide a method for connecting a shaft structure to a traffic area surrounding the shaft structure.

PRESENTATION OF THE INVENTION

According to the invention this is in a component for connecting a shaft structure to a traffic area surrounding the shaft structure with a first and second end face, a front and a back, and a lower and a

Upper side, achieved in that it is a component made of mastic asphalt mold component. Under mold component is a component understood, in addition to the usual cuboid form of conventional components, such as

For example, the paving stones mentioned, may also have different forms of this. The production of

Moldings according to the invention are made by casting in a mold, preferably made of steel. The mixture is pourable and spreadable when hot before curing, and requires no condensation work to cure it. The thus-obtained molded component is characterized particularly easy to manufacture, and can be made largely free depending on the mold in its shape. Thus, the profile of the second end face can essentially represent the negative contour of the first end side, wherein the negative contour of the first end face is understood to mean the profile of a shape which, when attached to the first end face, covers it in a form-fitting manner and without leaving behind opening areas. Inventive mold components are thus directly and form-fitting can be connected to each other and particularly easy to install. The use of molded components made of mastic asphalt is especially advantageous when the molded component in

Connection with a traffic area made of asphalt (mastic asphalt or compactable asphalt mixes) is used.

In this case, molded components according to the invention have the largely same modulus of elasticity as the surrounding component

Traffic surface, whereby a relative shift to

Asphalt and the associated ramp formation is minimized. The formation of cracks is largely avoided, resulting in less wear, increased weather resistance, increased safety and increased ease of use

In a particularly preferred embodiment, the profile of the first end face exactly two stages and the profile of the second end face exactly one step.

The two stages are the first face

preferably arranged such that their edges are visible in a plan view of the top of the mold component and the one step of the second end face preferably arranged such that its edge is visible in a plan view of the underside of the mold component. A plan view of the front side of the molded component therefore shows a shape that is essentially one

Parallelogram is similar. As a result, the joining of the mold components is particularly stable and easy to implement.

Furthermore, it is preferably provided that a first normal distance between the upper side of the molded component and the edge of the next closest to the top level of the first

Front side is smaller than a second normal distance between the top and the edge of the stage of the second end face.

Back of the mold components in a preferred

Embodiment parallel to each other, and each form a portion of a cylinder jacket. The latter feature contributes to the fact that a self-contained circular ring of molded components can be created by appropriate juxtaposition of molded components.

In order to provide high mechanical strength, it is envisaged that a molded component according to the invention

is closed on all sides. A closed structure is also easy to implement and low

Associated production costs. In a further embodiment of the invention it is

provided that the top of the molded component of the solidified mastic asphalt outstanding, coarse-grained elements, preferably hard chippings, in order to make the surface rough and handy. This can contribute to the risk of accidents
