Description

Component arrangement for creating a foundation

The invention relates to a component arrangement for creating a foundation for roadways, petrol stations, assembly halls, car washes or the like. Structures according to the preamble of claim 1.

The invention is concerned with the problem of creating a component arrangement for creating a foundation for carriageways, petrol stations, assembly halls, car washes or the like, which is suitable for customer-specific different facilities with little technical effort and reduced assembly time and with reduced production costs and improved environmental protection allows a variable design as a liquid-tight system.

The invention solves this problem with the component arrangement for a foundation, for example for a petrol station, a roadway or a car wash, with the features of claim 1. With regard to further essential configurations, reference is made to claims 2 to 35.

The structure of the foundation according to the invention is characterized by prefabricated and modularly connectable concrete individual parts which, as a variable assembly unit in the installed position, form a functional surface which is optimally matched to the surroundings. This allows a central support element, for example an island plate of a gas station, to be joined together with parts of the roadway adjacent as a functional area in a comparatively short time, so that a liquid-tight floor covering is achieved in the connection areas of the individual parts after a joint sealing. This foundation construction meets even at high

BESTATIGUNGSKOPIE mechanical loads, in particular due to vehicle movements, the high demands on the protection of the environment, since the assembly unit as a whole forms a fluid-tight system.

The individual parts prefabricated in a concrete plant are limited in their maximum weight for easy transport, for example to 1,500 kg, and can be stored on the installation site with little effort and simple auxiliary devices on a base layer prepared on the ground side, so that a considerable reduction in the construction time for such lanes, Petrol station systems, assembly halls, car washes or the like.

The assembly unit is designed as a kit with individual parts that can be adapted to customer-specific requirements with little effort. The parts can be positioned as precisely fitting assemblies without additional adjustment effort in precisely plannable assembly positions and then a simple and quick sealing, for example with a polysulfide sealant or the like, is possible in the area of boundary joints of adjoining components. The entire assembly unit thus forms a fluid-tight sealing joint structure which leads to a drainage of surface liquid and is connected to a cleaning system, so that floor areas located under or next to the foundation are protected against infiltration of surface liquids such as mineral oils or the like.

In an advantageous embodiment of the concrete elements, they are shaped in the region of peripheral support profiles with profile teeth which have receiving spaces which can be connected to associated elements. These tooth spaces are shaped with a recess enlarging their receiving contour so that the support profile of the associated Concrete element with the respective profile tooth is received in this recess. This means that even with an inclined position of one of the concrete elements on an inclined partial area of the sub-floor, a sufficiently positive connection and a stable support of the adjacent concrete elements is achieved.

These recesses are adapted in their dimensions to the respective dimensions of the profile teeth, so that they are detected over a large inclination range over their entire length in the extended on space of the recess. A wedge-shaped configuration of the recess towards the bottom of the concrete element ensures that the foot-side area of the associated profile tooth tilted in the receiving space is securely grasped, pressure and shear loads are absorbed over a large supporting cross-section and thus the fracture resistance in the area of the seal structure underlying support profiles is increased. With the recesses it is achieved that the joint formed between the concrete elements in the installation position above the respective support profiles has a uniform upper opening width and thus a constant joint dimension is achieved even when the parts are in a tilted installation position and uniform conditions are created for the introduction of the sealing material.

Further details and advantageous refinements of the invention result from the following description and the drawings, which illustrate several exemplary embodiments of component arrangements according to the invention. The drawing shows:

In Fig. 1, a foundation designated overall 1 is shown, which is provided as a bottom-side component arrangement for building a gas station or the like. Buildings on a prepared base layer 2 (Fig. 6). The foundation structure 1 has an island plate adjoining a roadway area 3 as a functional area and receiving one or more petrol pumps (not shown) as a supporting element 4, which has respective openings D for line parts or the like. Accessories and is provided with a support zone Z, in whose area roof elements, beams or the like. (not shown in more detail) modules of the gas station device are held.

The component arrangement of the foundation 1 according to the invention is constructed in the functional area 3 and / or in the area of the support elements 4 from prefabricated individual parts which form a effective assembly unit M are connected as a liquid-tight floor covering. In the area of a petrol station (FIG. 1), the island plate is integrated as a central supporting element 4 in the roadway area 3, which is composed of individual parts and forms an outer edge 6, as a functional surface.

In FIG. 12, the individual parts of the assembly unit M are illustrated in a perspective representation (in the form of a structural drawing of the system containing inclination dimensions), the individual parts being laid in the area of respective joints F (small sectional representations according to FIGS. 12.1 and 12.2) forming contact surfaces that in each case parts of the island plate 4 and associated base plates 5 adjoin one another. In this installation position, the inclinations N, N ', N' 'which run to the outer edge 6 (FIG. 1) of the roadway area 3 and are integrated into the floor covering are clearly evident, so that a seal structure (FIG. 11) provided in the joints F is used for one Outer edge 6 directed discharge of surface liquid is reached.

The embodiment of the mounting unit M in FIG. 1 illustrates that this with the island plate 4, the bottom plates 5th

(Fig. 5) or hexagonal stones 5 '(Fig. 1) and the outer edge 6 forming ramp stones 7 (Fig. 9) forms an expandable kit which is positioned on the base layer 2 (Fig. 4) prepared on the bottom. The individual parts can then be fixed in this installation position, for example in the region of the island plate 4, by holding parts generally designated 8, 8 'and in the region of the adjoining contact surfaces of the individual parts 5 and 5', at least in some areas, in the connecting gap

(Joint F) introduced sealant 9 (Fig. 11, e.g. ^' Poly- sulfide) the fluid-tight sealed seal structure is formed.

In an expedient embodiment, the sealing construction is designed in such a way that respective guide channels L (FIG. 11) are formed in the driving surface with the sealing of the joints F, in which liquids flowing away from the mounting unit M are received and in each case in the outer edge 6 of the road area 3 integrated collecting channels 10 are derived. In the area of the collecting channels 10, separators (not shown in detail) can be provided, so that in particular polluted surface liquids in the area of petrol stations can be disposed of in an environmentally friendly manner.

The enlarged representations according to FIGS. 2 and 3, taken together with the sectional representation according to FIG. 4, illustrate the individual part structure of the island plate 4, which consists of two side parts 11 and 12 and a middle part 13 clamped between them. A bollard element 14, 15 is supported at each end on the two side parts 11, 12. To accommodate these bollard elements 14, 15 provided as protection for the fuel pumps, the side parts 11, 12 are each formed with a step 16 effective as a contact surface, so that a stabilizing installation position is achieved (FIG. 3) and the bollard elements 14, 15 are subjected to an impact load without Can accommodate displacement.

The connection between the two side parts 11, 12 and the central part 13 is stabilized in a practical embodiment by the holding parts 8 designed in the form of screwed plates, and additionally in this embodiment the assembly unit M is in the area of the connecting surfaces S (FIG. 2) of the parts 11, 12 and 13 one as a locking device effective and shaped in the form of a tongue and groove connection circumferential profile (Fig. 3) provided. This is formed in the middle part 13 by respective groove-shaped recesses 34, 35, into which the respective form extensions 36, 37 of the side parts 11 and 12 engage.

3 also shows that respective frame parts 17, 18 are provided in the area of the side parts 11, 12 on the top side. In the area of the frame parts 17, 18, a tank column (not shown) can be installed with little assembly effort, which can be connected to corresponding line systems of a supply system of the petrol station via a passage opening 19, 19 'running as a bottom channel.

The middle part 13 supported between the two side parts 11, 12 also has passage openings 20, 21 which are advantageously provided with respective conduits laid in the form of empty pipes. In this way, additional line connections, for example electrical cables, roof drainage or the like, can be introduced into the assembly unit M with little effort. In the middle part 13 additional receiving parts 22 are cast, which in particular form the top support zone Z for roof element carriers, not shown. At 23 the connection of an electrical potential equalization is provided. In particular, anchor bolts are provided as receiving parts 22, which are connected to a base plate held in the concrete part. When this assembly (not shown) is poured into, for example, concrete (B 25), respective empty tubes E (FIGS. 2, 3) are grouped around the anchor bolts, so that they are accessible for assembly after the concrete has hardened and are in the correct position in their connection position aligned can be. The. The area towards the empty pipes E can then be filled with filler material.

FIG. 4 illustrates the above-described embodiment of the three-part island plate 4 in a sectional view, further individual parts of the assembly unit M (FIG. 10) adjoining the island plate 4 becoming clear.

5 shows a further embodiment of the assembly unit M, the central part 13 in the region of the island plate 4 having a respective intermediate part 24, 25 on both sides toward the side parts 11, 12, on which the respective frame parts 17, 18 for receiving the fuel pump are provided. 6, it is clear that the central part 13 is gripped by a quiver part 17 embedded in the floor, with which an additional support assembly, for example for a roof element carrier or the like, is formed below a central opening 28 in the central part 13 is.

In the embodiment of the respective lane areas 3 in FIGS. 5 and 7, respective base plates 5 are provided as individual parts, which are supported essentially on the same level (FIG. 6, FIG. 8) with the island plate 4 on the base layer 2 and in the region of the outer edge 6 have respective holding parts 8 '. In an expedient embodiment, the base layer has a mortar layer 29 provided on the floor 26 as a top layer, over which a fine planum 30, in particular for producing the inclinations N, N ', N''(FIG. 12), can be applied. It is also conceivable that the lane areas 3 with hexagonal shaped stones 5 '(Fig. 1) are designed, the respective joint areas F of which are also provided with the sealing structure (FIG. 11).

7 shows the island plate 4 in an installed position in which the carriageway area 3 adjoins the island plate 4 on one side in the area of a longitudinal edge L '. The base plates 5 have a corresponding inclination N, N ', so that a liquid discharge is achieved towards the collecting channels 10. In all of the illustrated embodiments, the respective outer edge 6 of the carriageway area 3 is shaped in the manner of the ramp stone 7 (FIG. 9, right side). Thus, the roadway areas 3 as a liquid-tightly sealed floor covering are limited at the edges so that even in the case of large amounts of liquid on the driving surface, a crossing into the adjacent areas is avoided.

The partially sectioned illustration of the island plate 4 or of the bollard element 14 according to FIG. 9 (left side) illustrates on the side parts 11 ', 12', 13 '(FIG. 8) a molding area P which is designed as an upstand 56, that liquid located on the island plate 4 is retained in the manner of a splash guard and thus the safety requirements are met in the area of the fuel pumps.

In FIG. 10, an enlarged detail view according to view X in FIG. 8 shows the integration of the frame part 17 'in the region of a passage opening 20' in the middle part 13 '. The passage opening 20 'is closed on the upper side with a lid molding 31.

In FIG. 4 and FIG. 1, shaft assembly kits 32, 33 are located on the edge next to the side parts 11, 12 Island plate 4 attached. The respective top-side modules 34, 35 adjoin the side elements 11, 12 in the vicinity of the bollard elements 14, and the modules 34, 35 are integrated in the floor covering 3. The manhole kits 32, 33 form a respective manhole cover, which is provided above a respective access opening 36, 37 to a tank container 38, 39.

FIG. 13 shows a base plate 50 provided as an individual part for an assembly unit M ¹ (FIG. 14) in a third embodiment. This base plate 50 is provided with a receiving channel 43 which runs parallel to its upper side 40 and opens out on two opposite side surfaces 41, 42 and which, in the manner of the passage openings 19, 19 'and 20, 21 (FIG. 2), can be used for various purposes is.

With their trough-shaped, usable surface 40 on the top, several of the base plates 50, 50 'form a functional area which can be used together with the receiving channels 43 integrated in the base plates 50, 50' (FIG. 14). The outputs of the receiving channels 43, 43 'adjoin one another in the installed position of the base plates 50, 50' and are coupled in a fluid-tight manner via a connecting part 44 (FIGS. 15, 16) in such a way that the assembly unit M 'in addition to the functional area on the top with the usable area 40 has an inner functional channel.

In the illustration according to FIG. 14, the middle of the base plates 50 'has two receiving channels 43 and 43', these forming a branch at 45 in some areas. It is also conceivable that several, also crosswise, channels are provided within the base plates 50, 50 ' (not shown) . The front view according to FIG. 16 illustrates that the receiving channel 43, 43 'preferably have a circular cross-section, polygonal contours also being conceivable (not shown).

The receiving channels 43, 43 'of the adjoining floor plates 50, 50 "overall form a conduit system which can be integrated into the pavement of a roadway and can be used in combination with the usable surface 40 on the top. These floor plates 50 have respective profile projections 46 and 47 on the top side, so that the usable area 40 is limited in the manner of a trough W. (FIG. 13) This limitation by means of profile elevations 46 and 47 running parallel to the central longitudinal plane U results in an essentially linear boundary course next to the usable area 40 when several floor plates 50 of this type are laid.

14, the base plate 50 'is provided with respective angled profile elevations 47' on one side of the tub W. This makes it clear that with variable contours of the base plates 50, 50 ', T-shaped courses of the usable surface 40, 40' can also be achieved. It is also conceivable that the profile elevations 46, 47 form a usable surface 40 with a cross-shaped course (not shown).

With the above-described, profiled floor plates 50, 50 ', driving surfaces can be designed on which corresponding movement paths for vehicles are limited and specified by means of the edge profiles 46, 47, 47'. It is conceivable that the profile elevations 46, 47, 47 'can be used as a lateral wheel guide or serve as a guide for automatic vehicle control. The usable areas 40 of the base plates 50, 50 'can be used as driving surfaces, in particular for (electromotive) vehicles with an indirect power draw, with corresponding energy supply lines (not shown) being laid in the receiving channels 43, 43'. It is conceivable, for example, for contactless current consumption by magnetic fields in the area of lines in the receiving channels 43, 43 '. Such a contactless transmission (current collector 60) of the drive energy can currently be implemented over a distance 60 '(FIG. 13) of approximately 15 cm. The stability of the base plates 50 is such that largely any (motor-driven) vehicles can be moved on the usable surface 40 and neither the profile elevations 46, 47 nor the component-integrated energy supply in the receiving channels 43 are influenced. The base plates 50, 50 'can be designed as individual parts for the assembly unit M', for example with a length A of 5000 mm and a width B 'of 2500 mm (FIG. 14).

15 and 16, the connection area between the receiving channels 43, 43 'is on different base plates

50 and 50 'in an enlarged individual illustration, it being clear that a sealing ring 51 is fixed by screws 52 having clamps 53, 54 as a connecting part 44 in the joint F'. The joint F 'has a receiving space 55 between the two base plates 50 and 50' into which the connecting part 44 can be inserted from above. The sealing ring

51 in the installed position between the two receiving channels 43 and 43 'and then by means of the clamping screws

52 the elastic sealing ring 51 can be clamped radially. Here, the sealing ring 51 with the width 61 (Fig. 15) of the clamps 53, 54 emerging system parts, pressed against the side faces of the receiving space 55 and thus achieving a fluid-tight seal of the receiving channels 43, 43 'to the joint F'.

17 to 19, the base plate 5 (FIG. 5) is shown in respective individual views, a toothing profile (tongue and groove profile) being evident on the side surfaces 57 and 58 which act as a contact surface in the mounting position (FIG. 5). These serrations of the base plates 5 engage in one another in the installed position so that if a single plate is damaged, replacement is possible.

On the opposite longitudinal side surfaces 57 and 57 ', respective tooth gaps 59 are formed, which can accommodate a carrying strap provided as an assembly aid (not shown) so that the base plate 5 can be installed with little effort. Such tooth gaps as shape recesses are also conceivable on the base plates 50, 50 'according to FIG. 14 (not shown).

In the installed position, the tooth gaps 59 form respective access openings through which filling materials, for example fire-dried sand, mortar or the like, can be introduced under the plates 5, 50, 50 '. This is particularly necessary if slabs with different heights lie against each other and voids are created on or under the foundation. By pressing, inserting and / or slurrying the filling material through the tooth gaps 55, cavities and joint chambers can be filled and the hooked components of the assembly unit M, M 'can thereby be additionally stabilized. 20 shows two concrete elements 101 and 102, which are provided in particular as floor slabs (similar to FIG. 12) and are laid in the form of a paving stone, a plate part or the like as a floor covering on a substrate 103. This side view, in conjunction with the partially sectioned top view in FIG. 21, makes it clear that the concrete element 101 is provided in the region of its side face 104 with a support profile alternatingly having a profile tooth 105 and a receiving space 106 and oriented perpendicular to the top side 107 of the concrete element, which in Laying position can be connected to the associated concrete element 102 in the manner of a toothing (FIG. 22, FIG. 23).

In this embodiment of the concrete elements 101, 102, the receiving space 106 of the support profile is provided with a recess 108 at least in some areas. The side view according to FIG. 20 illustrates that the cutout 108 forms an extension toward the bottom side 109 of the concrete element 101, 102, whereby this extends in a wedge-shaped manner (angle K, FIG. 20) in the manner of a receiving pocket towards the underside 109 of the concrete element.

22 and 23 show the connection engagement of the support profiling according to the invention when the two concrete elements 101 and 102 are positioned on a horizontal surface 103 (horizontal plane G = +/- 0 °). In this case, the profile teeth 105 engage in the respective receiving spaces 106 with their side surface regions 104 'parallel to a vertical vertical axis H' (FIG. 22). In this known connection position of the concrete elements 101 and 102, the cutouts 108 are not covered by the toothed support profiles 105 and 106 (FIG. 23). 24 and FIG. 25 show the laying position of the adjacent concrete elements 101 and 102 on a substrate 103 'which has an inclination R or R' which runs in opposite directions to an imaginary horizontal plane G and which in turn is in the region of the central longitudinal plane H ' define an apex S '. When the two concrete elements 101, 102 are shifted into the installation position (FIG. 24, arrow E, E '), the concrete elements 101, 102 are shifted in such a way that the support profiles interlock similarly to FIG. 22. 25, a complete connection engagement of the respective profile teeth 105 in the receiving spaces 106 is achieved in that the profile teeth 105 can be displaced into the area of the cutouts 108 and thus those with the bottom-side inclination R, R 'in one Inclined concrete elements 101, 102 are fully interlocked with their profiles. With this optimal form fit of the concrete elements 101 and 102, the stability of the connection is ensured and an optimal formation of the joint F '' running above the support profile is achieved. The cutouts 108 each extend only over a partial area T of the height B of the side surface 104 (FIG. 20).

In the area of the joint F ″, a seal 110 with a lower sealing cord 111 and an upper polysulfide layer 112 can be provided, which is also protected against loads by the teeth of 105 and 106 if subsidence in some areas after the installation of the concrete elements 101, 102 lead to warping or inclinations in the composite of the floor covering.

26 and 27 show a second embodiment of the concrete element 101 'designed as a curb 113 with the recess 108, this being connected on the one hand to the previously described concrete element 101 in the form of a paving stone or the concrete slab. The curb 101 'is on the horizontal plane G (Fig. 27) and the concrete element 101 is assigned to it with the inclination R ″. In this laying position, the support profiles engage in one another, as shown in FIG. 25, such that the recesses 108, in their complementary receiving cross section, almost completely accommodate the assigned partial area of the respective profile tooth 105.

In a further embodiment, not shown, it is conceivable that the receiving spaces 106 are extended towards the top 107 of the respective concrete element 101, 102, so that a corresponding tilting of the components is possible if the profile teeth 105 forming the positive locking of the support profiles have a corresponding complementary design are formed. For this purpose it is provided, for example, that the profile teeth 105 have a shape-widening on the foot side which is designed in the form of an illustrated shoulder wedge 115 (similar to angle P 'in FIG. 28). In the case of a tilting position of the concrete elements in the installation position opposite to the inclinations R, R ', R' ', the recesses (not shown) extended to near the upper side 107 can grasp the respective profiled teeth 105 with this extension wedge 115 in such a way that their base-side extension wedges 115 likewise rest in the connecting position and thus a locking of the components is guaranteed even on the inclined surface inclined upwards (not shown).

28 and 29 show a second embodiment of the respective recesses 108 'and complementary profile teeth 105' having concrete elements 101 '' and 102 '', respectively. These profile teeth 105 'are formed with the shoulder wedge 115, so that in the installed position, a joint F ¹ ' (FIG. 29) having parallel side walls 104 down to the depth 116 is formed. The joint F ″ is dimensioned larger in the region 116 than in the region of the depth 116 ′ in FIG. 22. In addition to the sealing, the joint F ″ is cord 111 (FIG. 25) and the polysulfide layer 112, a protective layer 117 is introduced, so that the seal 110 'is made in three layers. In this joint F '', the elastic polysulfide layer 112 is so deep that its damage by penetrating parts, for example pointed objects on factory floors, junkyard covers or the like, is hardly possible and nails, chips or the like do not reach the sealing compound 112 , In addition, the depth 116 of the joint F ″ is dimensioned such that the protective layer 117, which in particular has epoxy resin or polyurethane as a hard joint compound, can be introduced to a sufficient thickness. This protective layer 117 can become detached when one of the concrete elements 101 ″ and 102 ″ is displaced (for example tilting) in the region of one of the side edges (at 118), so that afterwards the protective effect for the elastic layer 112 is still guaranteed and this in turn during the Displacement is undamaged due to its elasticity. Above the seal 110, a bevel 119, known per se, is provided on the concrete elements 101 ', 102', which merges towards the upper side 107 into a circumferential lowering step 120, so that this break-prone area is protected against damage from edge overloading.

The contour of the shoulder wedges 115 is shaped in accordance with the enlarged opening angle K 'having recesses 108 towards the underside 109 so that for the connection situation of the elements 101''and102''shown in FIG , In the event of a conceivable tilt displacement (arrow 121) of the element 101 ″, there is sufficient gap play in the area of the spacing dimension 120 ′. This can also be used in particular when the parts 101 ″, 102 ″ are in an inclined position (similar to FIGS. 25 and 27). •
