FRAME SYSTEM AND MANHOLE COVERING

Abstract

The invention relates to a frame system (1) for a manhole covering (100) having at least one first frame element (10) and one second frame element (20), which each include at least one first connecting surface (10a; 20a) and/or at least one second connecting surface (10b; 20b). The first and second frame element (10; 20) are connectable to one another in a friction-locked and/or formfitting manner along the opposing first or second connecting surfaces (10a; 10b; 20a; 20b), wherein in the connected state of the first and second frame element (10; 20) at least one joining region (12) is formed between the opposing first connecting surfaces (10a; 20a) or between the opposing second connecting surfaces (10b; 20b). The joining region (12) can be filled using a joining element (60) in such a way that the joined connection of the frame elements (10; 20) is detachable and reproducible wherein the joining element (90) comprises a hot melt adhesive. Furthermore, the invention relates to a manhole covering (100) having a manhole cover and such a frame system.

[0035] FIG. 5 shows a perspective detail of the joined connection of the second to a third frame element along second connecting surfaces.

[0036] FIG. 1 shows a manhole covering 100 having a frame system 1 and two manhole covers 2. In contrast, FIG. 2 illustrates the frame system 1 according to FIG. 1, but without the manhole covers 2.

[0037] According to FIG. 1, the frame system 1 includes a total of eight frame elements 10; 20; . . . ; 80 having different lengths. Each of the frame elements 10; 20; . . . ; 80 is formed having a first connecting surface 10a; 20a; . . . ; 80a, in the form of a corner connecting surface, and a second connecting surface 10b; 20b; . . . ; 80b, in the form of a lateral connecting surface. Accordingly, each of the frame elements 10; 20; . . . ; 80 according to FIG. 1 adjoins a corner of the frame system 1 with its lateral end.

[0038] Between adjacently arranged frame elements 10; 20; . . . ; 80, the respective first connecting surfaces 10a; 20a; . . . ; 80a or second connecting surfaces 10b; 20b; . . . ; 80b opposite to one another form an individual joining region 12; 23; 34; 45; 56; 67; 78; 81. A joining region 12 is provided between the first and second frame element 10; 20, which can differ, for example, from the joining region 56 between the fifth and sixth frame element 50; 60.

[0039] Furthermore, a joining element 90 is provided in each of the joining regions 12; . . . ; 81, for the preferably complete filling of the respective joining region 12; . . . ; 81. Exact filling can thus be provided for each individual joining region 12; . . . ; 81 by means of the joining element 90, in particular by having the joining element 90 flow in or pouring it in a liquid physical state into the respective joining region 12; . . . ; 81.

[0040] In that the joining element 90 preferably includes a hot melt adhesive, in particular a co-polyamide, furthermore a nondestructive disassembly of the assembled manhole covering 100 or the frame system 1 and complete reproduction thereof can be provided. Inter alfa, simplified transport and reassembly can thus be provided at the usage location.

[0041] FIG. 3 shows a perspective enlarged view of a joined connection of the first frame element 10 to the second frame element 20.

[0042] It is apparent from FIG. 3 that the first and second frame element 10; 20 are connected to one another in a friction-locked and/or formfitting manner by means of two connecting elements 4 in the form of screw-nut connections. A connection of the frame elements 10; . . . ; 80 to provide a sufficiently stable frame system 1 for a manhole covering 100 is thus available.

[0043] In particular, the frame elements 10; . . . ; 80 can include corresponding through holes, in particular two through holes in each case according to FIG. 3, along the first and/or second connecting surfaces 10a; 10b; 20a; 20b . . . ; . . . 80a; 80b, for expediently receiving the connecting elements 4.

[0044] The first connecting surfaces or corner connecting surfaces 10a; 20a of the first and second frame element 10; 20 are oriented opposite to one another. A joining region 12 is formed between the first connecting surfaces 10a; 20a of the first and second frame element 10; 20. The joining region 12 is completely filled up using the joining element 90.

[0045] FIG. 4 shows a perspective sectional view of the connection of the first to the second frame element 10; 20 along the first connecting surfaces or the corner connecting surfaces 10a; 20a. In this meaning, FIG. 4 shows the joining region 12 between the first and second frame element 10; 20, which is filled up using the joining element 90.

[0046] According to FIG. 4, the joining element 90 extends completely over the first connecting surfaces 10a; 20a after the filling or filling up of the joining region 12. In this meaning, the cast joining element 90 is to be understood in the meaning of a seal or the like, which images the contour of the first connecting surfaces 10a; 20a and thus completely fills up the joining region 12. Furthermore, two through holes along the first connecting surface 20a of the second frame element 20 can be seen, through which the connecting elements 4 extend, preferably during the casting using the joining element 90.

[0047] FIG. 5 shows a perspective detail of the connection of the second to the third frame element 20; 30 along second connecting surfaces 20b; 30b.

[0048] The second and third frame element 20; 30 are also connected to one another in a friction-locked and/or formfitting manner by means of preferably two connecting elements 4.

[0049] The second connecting surfaces 20b; 30b opposite to one another form the associated joining region 23 located in between. According to FIG. 5, the joining region 23 is completely filled up or filled using the joining element 90. One expedient embodiment of the joined connection is thus provided between the second and the third frame element 20; 30.

[0050] In summary, by means of the present invention, a frame system 1 which is advantageous to produce, can be transported, and can be disassembled and assembled multiple times is provided for a manhole covering 100, wherein tolerances of the individual components can be compensated for in such a way that an exact formation of the manhole covering 100 can be provided.

[0051] Each individual joining region 12; 23; . . . ; 81 can be filled individually here with the joining element 90 expediently and with very simple conditions, wherein furthermore nondestructive disassembly and a system reproducible completely in a functional aspect are provided.

[0052] It is to be noted at this point that all above-described parts are claimed as essential to the invention seen alone and in any combination, in particular the details illustrated in the drawing. Modifications thereof are routine for a person skilled in the art.
