Description

The invention relates to a mounting pit according to the preamble of claim 1, a mounting device with such a mounting pit and a tank for liquid dangerous goods and the use of a cavity in a double-walled side wall of such a mounting pit for the storage of liquid dangerous goods in a tank.

Assembly pits are used by workshops or manufacturing plants for the assembly, repair or maintenance of motor vehicles, rail vehicles, machinery or machine parts. The staff can work in a comfortable upright position under the appropriate vehicles and machines.

Conventional assembly pits are usually made on site. For this purpose, first outer and inner shuttering walls are placed, which are then filled with filling material, preferably with concrete. The setting up of these casings or the production of conventional assembly pits may require long employment of a variety of partially different craftsmen on site, so that high production costs and long construction times occur. In addition, manufacturers prefabricated assembly pits, so-called prefabricated assembly pits, known with steel cassettes, which are used in a Bodenausnehmung on site. Typically, prefabricated assembly pits are made with sidewalls having an inner wall and a spaced outer wall with an intermediate cavity filled with a curable filler material such as concrete.

For reasons of environmental protection, it is increasingly necessary in workshops to ensure proper storage and disposal of liquid hazardous goods, such as waste oil. For example, in assembly pits, oil from engines, transmissions, hydraulic devices, compressors, machinery, and other industrial oils and lubricants are waste. In particular, in commercial vehicles such as buses or trucks an oil change is practically possible only with the help of a mounting pit from the vehicle underside, the vehicle is driven over the mounting pit and the waste oil is discharged into a collection or collection container, which is emptied from time to time. Due to the fire protection regulations, a suitable storage space for waste oil, in particular a tank designed for this purpose, must be available in workshops, which in particular must meet the requirements of certain fire resistance classes. Such tank systems often require expensive buried underground lines and must be monitored.

From the EP 2 728 090 A1 For example, an assembly pit for vehicles with a steel cassette is known, the side walls of which have an inner wall and a spaced outer wall defining a cavity filled with hardenable filling material. The cassette has a separate collecting space for receiving a collecting container for liquid dangerous goods. The separated collection space is either separated by a partition, in the interior of the cassette or as a lateral extension of the cassette, outside of a longitudinal or end wall adjacent, provided. Such a collecting space for a mounting pit has a lot of space. The available working space in the mounting pit is smaller by the collecting space or the establishment of a mounting pit by a lateral extension consuming, for example, due to the necessary adapted thereto and larger Bodenausnehmung or necessary manufacturing or adaptation work on site.

Based on this prior art, the present invention seeks to provide a mounting pit with a storage space for liquid dangerous goods, which has a smaller footprint. In particular, the available work space should not be reduced by the storage room and a mounting pit to be set up quickly and easily. In addition, a mounting pit with a storage room for liquid dangerous goods to operate safely and in particular meet the safety requirements.

This object is achieved by a mounting pit according to claim 1.

In particular, the wall thickness along the end faces 17 be different than the wall thickness along the long sides 18 , The pit body 10 can also be constructed asymmetrically, in particular with regard to the arrangement of the wall elements 19 , The thickness of a wall element 19 , which preferably consists of bent sheet steel, is typically 1 to 5 mm, preferably about 3 mm. The partitions 15 extend each height starting from the pit floor 14 into the area of the pit opening 21 , or to the pit edge 23 , The wall elements 19 are via welded joints with each other and with the longitudinal side inner walls 121 and frontal interior walls 122 connected. The wall chambers 11 have a stiffening effect on the pit body 10 ,

According to the invention is in the side wall 20 , here on one long side 18 , a storage room 3 with a tank in it 4 integrated for liquid dangerous goods. The storage room 3 is between the inner wall 12 and the outer wall 13 inside the side wall 20 arranged. This is the tank 4 saves space in the side wall 20 integrated. Those wall chambers 11 that have no storage space 3 can be filled with a curable filler material, such as lightweight concrete, from above. The wall chamber 11 that the storeroom 3 forms, as shown in detail C in 2 shown, however, is not refilled, but remains hollow, leaving the tank 4 finds room in it. One on one long side 18 integrated tank 4 may for example have dimensions of 1.2 m or 2.0 m height, 0.5 m width and 0.25 m depth, the depth being approximately the thickness of the side wall 20 equivalent.

There may be other wall thicknesses and wall thickness differences may be provided. By a self-supporting execution of the relevant wall chamber 11 Ensures that even large loads from the top of the pit body 10 can be derived to the bottom into the ground, without the side wall 20 at this point laterally buckles and in particular by the tank 4 can be damaged. In the relevant wall chamber 11 itself, but also in the two adjacent wall chambers 11 , additional stiffening structures may be provided to increase the structural stability of the storage space 3 to ensure. The Tank 4 is here with a double-walled tank wall 42 with a tank inner wall 421 and a tank outer wall 422 executed. This is the tank 4 very safe and it can on an otherwise legally required drip tray below the tank 4 within the storeroom 3 be waived. The side wall 20 points in an inner wall 12 a wall duct 123 in the form of a circular opening into which, for example, a Ruhrstutzen for the implementation of various lines can be used sealingly. In the 3A and 3B is a schematic front view of a front side 17 the mounting pit 1 in the sidewall 20 integrated storage room with a tank inside it 4 shown. At the bottom is the tank 4 at the pit floor 14 , at the same time the storage room floor 27 forms over anchoring elements 28 , here as threaded blocks at the bottom of the storage room floor 27 executed, anchored, leaving the tank 4 secured against buoyancy, for example when water or out of the tank 4 leaked liquid the tank 4 otherwise it would be possible to swim up. Here is the buoyancy protection by both sides at the top of the tank 4 attached rods 44 educated. On the gas cap designed as a dome lid 43 is a vent line 31 connected and a leak detection device 41 is arranged on it. Also a filling line 32 (in the 3A and 3B not shown, see 5 ) is with the tank 4 for filling with the liquid dangerous goods, in particular to be collected waste oil connected. Electrical lines to the leak detection device 41 , a possibly provided overfill protection and / or a suction line 32 are through the wall duct 123 from the storage room 3 in the pit interior 22 feasible, the wall duct 123 , In particular, a pipe socket inserted therein, sealing, in particular hermetically sealing, to close, for example with fire protection foam. In the 3B is the front side inner wall 122 to be seen in a front view, where behind the storage room 3 inside the side wall 20 at the front 17 is integrated. The storage room 3 is through a storage room lid 26 closed up tightly. In the upper area of the front side inner wall 122 is one with a cover plate 251 tightly closed maintenance opening 25 provided over which the storeroom 3 if necessary, in particular for maintenance of the tank 4 , is accessible. At the bottom of the storeroom 3 is a passage opening 124 with a drainage device installed therein 30 , in particular a ball valve, shown on the liquid from the interior of the storage room 3 if necessary, can be drained. A liquid sensor 29 For example, it is designed as a magnetically actuated level switch that provides a fluid level in the storage room 3 detected and turn on a control lamp or can trigger an alarm. The partition 15 points in the height direction spaced from each other through holes 151 on, over the adjacent wall chambers 11 are connected, so that filled from above curable filler from a chamber evenly in the connected wall chambers 11 is distributed. Such through holes 151 are in the partitions 15 that the storeroom 3 limit, but according to the meaning of the invention does not exist.

In 4 are details of a storage room lid 26 and a maintenance opening 25 shown in a partial sectional view, wherein the cover plate 251 via a screw connection on the inner wall 12 , in particular a front side inner wall 122 or a longitudinal side inner wall 121 , is tightly fastened.

In 5 is an embodiment of a mounting pit according to the invention 1 with one under an entry or exit help 2 , which is designed here as a staircase, arranged storage room 3 with a tank in it 4 shown. The entry and exit help 2 leads from a pit opening 21 or a pit edge 23 to get an edge profile 24 runs around, sloping down to a walkable intermediate floor 16 in the interior 22 , The Tank 4 is recessed to save space compared to the walk-in intermediate floor 16 at the pit floor 14 via anchoring elements 28 anchored and in this way particularly space-saving in the pit interior 22 accommodated. One below the entry and exit help 2 arranged tank 4 may have, for example, dimensions of 1.2 m height, 1.6 m width and 0.5 m depth, the width being approximately the inner width of the pit body 10 equivalent.

It should be noted that all aspects of the invention described above for Seen alone and in any combination, in particular the details shown in the drawings, are claimed as essential to the invention. The same applies to the described method steps. Variations thereof are familiar to the person skilled in the art.
