Filter cover ! * «Oüev

The invention relates to a set consisting of profiles « set filter ceiling construction to accommodate vpe Xuft « filter cassettes. In the case of such co-structures, which are primarily used in spray chambers, there are usually Licherweiss the profiles according to ixt von lietallfeasterkonstruktionen sueammenschweißt. Disadvantage of such Constructions is the considerable effort for Aaakllnk- and welding work, a difficult transport large areas as well as the impossibility of providing the finished construction with © inesa permanent surface protection by hot-dip galvanizing.

The object of the invention is to provide a filter cover or to create a metal window construction that overcomes these disadvantages and with little cost. v / and using standard profiles and also easy to transport and use. mount is.

These objects are achieved by the invention in that the filter cover construction from appropriately cut to length profiles arranged at right angles to one another at intervals consists, which are releasably connected to each other, wherein Devices for holding the air filter boiler available.

.bin advantageous feature of the invention i8t _r that initially balancing the perpendicular bolted profiles pieces aue hoop be Brecht etc. 30 to compensate for the height differences, etc. that results in a uniform support surface for the cartridge. In order to achieve sufficient dimensional accuracy, it is expedient to hang up the iron straps and drill the screw holes with the same gauge, which is designed for the double purpose.

In the description that follows is a

Example of a filter ceiling within the meaning of the invention in more detail:

According to Fig. 2, the screw 8a is inserted into the threaded bores 8 dea Profilee 2 and dea band iron 2a to connect these two parts. The screw has a shaft 12 which extends over the screw head and which is guided through a 3ucb.Be 10 which narrows downwards in the manner of a stuffing box and which rests on the band iron 2a.
