Technical Field

The invention relates to a frame system for a well cover device, comprising at least one first and one second frame element. Furthermore, the invention relates to a well lid device.

Background

In the case of a manhole cover arrangement, seams or gaps are required for the mounting between the individual frame parts due to the different tolerances of the cover and the frame parts. In order to be able to compensate for the tolerances and at the same time provide a stable device, the joint is usually cast in lead. Thereby, the frame part and the cover of the well cover device can be made with an exact fit.

The use of lead for pouring joints, especially when hot, liquid lead is processed, requires special work protection measures when installing and possibly removing the well cover device.

In addition, lead has been listed as a regenerative toxic material during this time. On this basis, there follows stricter work protection regulations and the inclusion of lead in a highly interesting list of substances. Accordingly, the use of lead is expected to be limited in the future, and thus, a replacement material is required.

Disclosure of Invention

The invention is based on the object of providing a frame system, in particular for a manhole cover arrangement, which can be produced simply, cost-effectively and safely, can be installed in a simplified manner on site, is reusable, provides compensation for tolerances of precisely adapted designs, and is weather-resistant and wear-resistant. Furthermore, it is an object of the invention to propose a manhole cover arrangement.

According to the invention, said object with regard to the frame system is achieved by the subject matter of claim 1 and the object with regard to the manhole cover arrangement is achieved by the subject matter of claim 5. Preferred embodiments are given in the dependent claims.

In particular, the object is achieved by a frame system for a manhole cover arrangement having at least one first frame element and one second frame element, which each have at least one first connection face and/or at least one second connection face. The first and second frame elements can be connected to one another in a force-fitting and/or form-fitting manner along the first or second opposing connecting surfaces. In the connected state of the first and second frame elements, at least one joining region is formed between the first opposing connection surfaces or between the second opposing connection surfaces, wherein the joining region can be filled with a joining element, so that the joining connection of the frame elements is releasable and re-establishable. In particular, the joining region can be filled or filled with a joining element, in particular a hot melt adhesive, in the connected state of the first and second frame elements.

The invention is based on the basic idea that a seam or gap is formed between frame elements that can be connected to one another and is filled with suitable joining elements, so that tolerances of the frame elements or the components of the associated manhole cover can be compensated for.

Furthermore, the connected frame elements can be disassembled without damage after filling the joints with joining elements, so that disassembly can be effected for disassembling the transport frame system and for reinstallation at the site of use. Thereby, an advantageous manufacturing and simplified transport to the place of use of the frame system or the well lid arrangement may be provided.

In particular, according to the invention, it is proposed that at least one joining region is formed between the opposing first connection surfaces or between the opposing second connection surfaces, wherein the joining region, preferably only the joining region, can be filled with a joining element between the first and second frame elements, so that the joining connection of the frame elements is releasable and re-establishable.

Each frame member has a first attachment face and a second attachment face. A first connection surface is understood in the sense of the present invention to be, in particular, a corner connection surface, i.e. a connection surface in the corner region of the frame system. The second connection surface is preferably understood to be a lateral connection surface, i.e. a connection surface extending in the lateral direction of the frame system. The first and second joint faces, i.e. the corner joint faces and the side joint faces, may have the same or different geometries from each other.

According to a first embodiment of the invention, the frame element according to the invention may have only corner connection faces, i.e. first connection faces, or only side connection faces, i.e. second connection faces. Furthermore, the frame element according to the invention may according to the second embodiment of the invention have a corner connection and a side connection with the respective corner connection face and side connection face, respectively.

The joining region between the two opposing connection surfaces of the two frame elements can be filled by means of the joining element. In particular, when the frame elements are expediently connected to one another and form a joining region, the joining element can expediently be inserted or injected into the joining region. In this way, in the sense of the invention, adjacently arranged frame elements can be joined along their connection faces directed opposite one another.

The non-positive and/or positive connection of the frame elements and the engagement by means of the engagement elements are releasable and re-establishable.

Hereby, the joint connection can be disassembled without damage and can be completely re-established in a suitable and practical manner. The joining elements are designed such that the function of the joining connection between the frame elements can be fully provided again after the reassembly.

It is achieved that the frame system is fully assembled during manufacture and the engagement elements are suitably introduced, followed by disassembly of the frame system, transport to the place of use and re-complete assembly on site. Thereby, a simplified manufacture and an optimized transport and use of the frame system according to the invention is ensured.

According to one embodiment, the joining region can be cast by means of the joining element, so that the joining element can be introduced into the joining region in the connected state of the first and second frame elements.

The joining element can be introduced as a fluid into the joining region, so that the fluid joining element can expediently, in particular completely, fill the joint formed between the first and second frame elements. The small joining region and the varying cross section of the joining region can thus be filled appropriately. Preferably, only the joining areas between the frame elements connected to one another are filled with joining elements.

The joining element can change its state of aggregation to a solid after a hardening process or hardening procedure within the joining region. In particular, the joining element can change its state of aggregation during a temperature change, so that the joining element adopts a fixed state of aggregation when the temperature decreases. Preferably, the joining element has such a melting temperature that the processing of the joining element is simplified.

According to one embodiment, the joining element has a hot melt adhesive. In this context, the joining element can be transformed into a fluid or flowing aggregate state by a temperature increase and injected or introduced into at least one joining region of the frame system.

In particular, the hot melt adhesive can have commercially available processing parameters, so that simple processing can be carried out without special protective measures, as are required, for example, when processing liquid lead. Thus, lead can be sufficiently replaced by hot melt adhesive as a bonding material.

Furthermore, the non-destructive detachment and re-establishment of the connection by means of the hot-melt adhesive bonding can be effected after the first bonding.

According to another embodiment, the hot melt adhesive has a copolyamide. The filling of the at least one seam of the frame system can thereby be realized with the aid of commercially available materials. Furthermore, a durable and weather-proof joint with sufficient mechanical properties can be provided, which is similar to a joint with lead.

In a preferred embodiment, the frame system has at least four frame elements, each having a first and/or a second connecting surface, wherein at least one joining region is formed between adjacent frame elements along the first or second connecting surface oriented opposite to each other, wherein in the connected state of the frame elements, in particular for forming the frame system, only the joining region can be filled with joining elements or with joining elements, respectively.

By filling only the joining region with joining elements, material savings and a reduced manufacturing time of the frame system can be achieved. In particular, only the regions required for tolerance compensation, i.e. the joining regions between the connecting faces of the frame elements oriented opposite one another, are filled with joining elements. Hereby, a more suitable and efficient use of the engaging element may be achieved.

According to a further embodiment of the invention, a manhole cover arrangement is provided, which has at least one first manhole cover and a frame system according to the invention. The frame system according to the invention can in this sense be used in particular with at least one corresponding manhole cover arrangement.

According to one embodiment, the at least one well lid can be fitted into the frame system by means of filling the at least one joining region with a filling element, wherein preferably, however, two or more seams are present and are filled, so that a sufficient and as simple as possible tolerance compensation between the lid element and the frame element can be achieved.

The tolerances of the frame element and of the at least one well cover can thereby be taken into account and adapted when forming the joining region and filling the joining region with the joining element. An exact matching design of the well lid arrangement is achievable.

In particular, the frame system can be assembled, at least one well lid is inserted into the frame system and then at least one joining region is filled or filled by means of the joining element, wherein, however, in order to achieve a sufficient and as simple as possible tolerance compensation between the lid element and the frame element, preferably two or more joints are filled. In this way, an accurate, play-free assembly of the well cover device can be achieved.
