Abstract

The invention relates to a supporting structure comprising at least one intermediate plane (12), especially a steel construction. The intermediate plane (12) comprises at least one frame (10) consisting of profiled elements (14, 16). The frame (10) can be detachably suspended on the supporting structure by a plurality of traction mechanisms (30).

Description

Supporting structure with at least one intermediate level.

The invention relates to a supporting structure with at least one intermediate level, in particular a steel construction.

Such supporting structures are used for example in industrial plants whose components are divided into several levels. Between these levels, in turn, the intermediate levels are appropriate. The intermediate levels are suitable to take loads, in particular to carry heavy components of the industrial plant. In known overhead conveyor systems, for example, rails and / or treadmills are mounted on the intermediate level below a hall ceiling. The intermediate level has a walkable floor, which prevents the falling of objects, such as workpieces.

From the market known intermediate levels are composed of solid steel floors and very heavy. They must therefore be mounted on support beams, which stand on the hall floor. These support beams hinder the free passage through the hall.

Object of the present invention is to design a support structure of the type mentioned, the intermediate level simple and space-saving, in particular special without the passage to obstruct, can be arranged.

This object is achieved in that the intermediate plane has at least one frame of profile elements and the frame via a plurality of traction means is releasably suspended from the supporting structure.

According to the invention, massive components are thus largely dispensed with in the construction of the intermediate plane.

Instead, it is realized in the form of a frame made of profile elements weight saving in lightweight construction. Profile elements have the great advantage that they have a high bending stability despite their low weight. The intermediate layer according to the invention which is considerably lighter in comparison to the known intermediate levels can thus be suspended from known hanging devices, in particular double-T carriers, below the hall ceiling. In this suspension construction can be dispensed with elaborate cross braces and support beams, especially in the form of truss structures. By the way, traction devices are significantly easier and easier to implement than support beams, since they do not have to have the rigidity against pressure or bending loads, as is required with support beams.

In a particularly advantageous embodiment, the profile elements may be made of section steel. Section steel is easy to manufacture and process and very stable. In order to achieve a high flexural rigidity, the profile elements can be C-edge profiles.

The traction means may be round rods. Round rods have the advantage that they have a high tensile strength and yet are very light. In addition, round rods are easy to produce especially in the meter.

Furthermore, each traction device can be fastened with one end to the frame via a particularly removable suspension device. Removable hangers have the advantage that they can be optionally attached. If the frame is composed of a plurality of frame modules, the suspension devices can be fastened to the free outer sides of the frame on two adjacent frame modules. But it can also be attached suspension devices at intersections, where the corners of four matrix-shaped arranged frame modules abut each other. The suspension devices can preferably be designed so that they transmit the train of all adjacent frame modules to which they are fixed to the traction means and additionally connect the frame modules firmly together.

Specifically, the traction means can each be connected via a Schraubspanneinrichtung with the frame. With the screw tensioning device, distances between the tension and the frame can be easily changed to align the frame horizontally.

In a further advantageous embodiment, the frame may have at least one in particular removable support device for the conveyor, in particular a rail or a conveyor belt. On the support device can also be easily mounted a cable duct. Since the support means are removable, they can be selectively attached there to the frame where the conveyor is to pass along.

In addition, the frame can carry at least one, in particular fastened with releasable fixing means grid. The grid serves as a protective grid, with which it is prevented that objects, in particular workpieces, which are transported with the conveying means, or tools, can fall off the intermediate plane. Horizontal gratings, which can also act as walk-on floors, and / or vertical ones, which act as a side boundary, can be used here

Lattice be provided. The grids can be modularly mounted to the frame and removed from it as needed.

The intermediate plane may be particularly advantageously composed of a plurality of frame modules, which are connected to each other with particular releasable connection means. In this way, the dimensions and the course of the intermediate level as needed to the hall and / or the funding will be adjusted. The detachable connections allow to change the structure of the intermediate level at any time.

FIG. 1 shows a frame module, generally designated by the reference numeral 10, of a horizontal intermediate plane 12, shown in plan view in FIG. 2, of an otherwise not shown structural steel supporting structure.

The frame module 10 carries a conveyor belt (not shown) known per se. The conveyor belt extends in Figure 1 from top left to bottom right (conveying direction). The intermediate plane 12 is composed of a plurality of such frame modules 10 (Figure 2). The conveying direction runs in Figure 2 from bottom to top. The frame module 10 is rectangular in plan view (Figure 2). Its transverse to the conveying direction sides are formed by two parallel, elongated carrier profile elements 14.

The carrier profile elements 14 are connected at their ends via two extending in the conveying direction, elongated connection connecting profile elements 16 with each other.

The carrier profile elements 14 and the connection profile elements 16 are C-shaped steel profiles. Their open vertical longitudinal sides point towards the interior of the frame module 10. At their end faces, the C-shaped profiles are also open. The C-shaped profiles are beveled at both ends by 45 ° to the open vertical longitudinal side, so that the connecting profile elements 16 and the carrier profile elements 14 at the corners of the frame module 10 in the form of a true miter collide vertically. In the region of the ends of the C-edge profiles, the closed vertical rear sides each have two continuous profile-side connecting holes concealed in FIG. 1 by machine screws 17, which lie vertically one above the other in pairs. The diameter of all profile-side connection holes is identical. The distance of the profile-side connecting bores of a pair and their distance to the corresponding end face of the C-shaped profile is the same for all profile-side connecting bores. The carrier profile elements 14 and the connecting profile elements 16 are connected to each other at their abutting ends via a suspension cross 18 shown in detail in Figure 4 in detail.

The suspension cross 18 includes, shown in the foreground in Figure 4, a carrier tab 20 in the form of a vertically arranged rectangular plate whose longer sides are aligned horizontally. The carrier lug 20 is divided in half in the longitudinal direction into two attachment regions, of which only the one pointing in the direction of viewing in FIGS. 1 and 4 can be seen.

Perpendicular to the opposite vertical surfaces of the carrier lug 20 in the longitudinal direction of each two plate-shaped hanger brackets 22 are mounted centrally. The suspension lugs 22 are arranged symmetrically to the carrier lug 20.

Each hanging tab 22 has two areas. An approximately rectangular lower connection region 22a terminates at the top with the upper edge of the carrier lug 20. In this connection region 22a, the suspension lugs 22 are fastened to the carrier lug 20. An upper suspension area 22b connects in one piece over the connecting area 22a. In the upper suspension area 22b, the side facing away from the other suspension strap 22 is inclined upwards at an angle to the other suspension strap 22. The suspension area 22b is thus perpendicular to the surface of the suspension. Hänglasche 22 considered approximately the shape of a right triangle, one of the catheters is horizontal and the other catheter is vertically aligned and connects seamlessly connected to the support bracket 20 vertical edge of the lower connecting portion 22 a. The upper, the lower connecting portion 22a facing away from the corner of the triangle is flattened horizontally.

The mutually facing vertical sides of the suspension areas 22b of the two suspension straps 22 define a gap 24 whose width is predetermined by the thickness of the carrier strap 20.

In both attachment regions of the carrier lug 20 and in the lower connecting regions 22a of the suspension lugs 22 are arranged vertically in pairs one above the other two perpendicular to the corresponding surface extending continuous hängkreuzseitige connection holes. The suspension cross-side connection holes are hidden in Figures 1 and 4 by the machine screws 17. The distance of the suspension cross-side connection holes of a pair and their diameter correspond to the distance and the diameter of the profile-side connection holes at the ends of the connection profile elements 16 and the carrier profile elements 14. The distance to the vertical axis of symmetry of the suspension cross 18 is identical for all suspension cross-side connection holes and slightly larger than the distance between the profile-side connection holes at the ends of the binding profile elements 16 and the carrier profile elements 14 of the end faces.

In each case one of the suspension lugs 22 and a fastening region of the carrier lug 20 form a rectangular clamp for connecting one of the connecting profile elements 16 to the corresponding carrier profile element 14. The clamp surrounds the ends of the vertically abutting profile elements 14 and 16 such that the surface of the hanger tab 22 facing the interior of the clamp area rests on the outside surface of the vertical rear side of the connection profile element 16 and the surface of the carrier lug 20 on the outer surface of the carrier profile element 14. In this case, the profile-side connecting bores in the profile elements are aligned with the corresponding suspension cross-side connecting bores in the carrier lug 20 or the suspension lugs 22. The machine screws 17, via which the profile elements 14 and 16 are fixed to the respective ones, are guided through the profile-side connecting bores and the suspension cross-side connecting bores Carrier strap 20 and the suspension hanger 22 are screwed.

In the columns 24 between the suspension areas 22b of the suspension lugs 22, a vertical threaded rod 28 is arranged on each suspension cross 18 coaxial with its center axis and fixed there. The diameters of the threaded rods 28 correspond to the width of the column 24. From The free end of the threaded rod 28 leads coaxially a round rod 30 upwards. The round rod 30 has at its lower end a rotatable relative to it but not axially displaceable sleeve 32 with internal thread, via which it is screwed to the threaded rod 28. The sleeve 32 acts in conjunction with the threaded rod 28 as Schraubspanneinrichtung over which the distance of the round rod 30 from the suspension cross 18 can be adjusted.

At their free ends, the round rods 30 are fixed via upper suspension elements 34 to a steel construction. The upper suspension members 34 are similar to the suspension portions 22b of the carrier tabs 20, but rotated by 180 ° and show with their flattened tips down. They are attached to the undersides of horizontal rectangular plates 36, which in turn are mounted, for example, on a not shown double T-section of the steel structure.

With the Schraubspanneinrichtungen the frame module 10 can be aligned horizontally and the height of the frame module 10 are adapted to the adjacent frame modules 10 of the intermediate plane 12.

In the section of the intermediate plane 12, which is shown in Figure 2, nine frame modules 10 are arranged flat. Where the corners of four adjacent frame modules 10 collide, a single suspension cross 18 is arranged so that its suspension tabs 22 relate to each other. The fastening areas of its carrier lug 20 are respectively clamped between the connecting profile elements 16 and the carrier profile elements 14 of the adjacent frame modules 10. In this case, each machine screw 17 passes through two aligned profile-side connecting bores of the connecting profile elements 16 or of the carrier profile elements 14 and a suspension cross-side connecting bore of one of the suspension lugs 22 or the carrier lug 20.

With the suspension cross 18 up to four frame modules 10 can be interconnected and suspended in the manner described above each at a corner. However, fewer frame modules 10, for example only two frame modules 10 at the edge or only one frame module 10 at a corner of the intermediate plane 12, can be hung on a suspension cross 18.

As FIGS. 1 and 11 show, the carrier profile elements 14 each have two support bodies 38 for the conveyor belt, each consisting of two T-shaped rectangular plates 46 and 47. On the support body 38, a conveyor belt support 40 is fastened with machine screws. The conveyor belt support 40 has an adjusting device 42 for height adjustment.

The vertical plate 47 of each support body 38 has four continuous, in Figure 1 through therein Screw 44 hidden holes on. Correspondingly, in the vertical rear sides of the carrier profile element 14 there are four continuous profile-side support bores, which are also covered in FIG. 1 by the screws 44 and are therefore not visible. Each support body 38 is fixed with the four screws 44 with its vertical plate 47 from the outside to the back of the carrier profile element 14. At the top, the vertical plate 47 ends above the underside of the carrier profile element 14. Above the vertical plate 47 projects beyond the top of the carrier profile element 14, so that the horizontal plate 46 of the support body 38 acts similar to a table on which the conveyor support 40th is attached (Figure 11).

Where two frame modules 10 abut one another with their carrier profile elements 14, as shown in FIGS. 2 and 11, the screws 44 pass through the two adjacent carrier profile elements 14 and the intermediate vertical plate 47 of the support body 38 and fix them in this way, the two frame modules 10 with.

Each frame module 10 also carries a horizontal walkable floor grid element 50 shown in FIG. 11. The floor grid element 50 has approximately the dimensions of the frame module 10 in plan view. It is provided at the edges with known, not shown, detachable screw clips on the upper side of the connecting element. Profile elements 16 and the carrier profile elements 14 attached. The vertical height of the bottom grid element 50 is smaller at its edge than the free area between the top of the carrier profile elements 14 and the horizontal plates 46 of the support body 38, so that the undersides of the horizontal plates 46 and the top of the bottom grid element 50 are spaced from each other.

In addition, 10 known, not shown vertical side rail elements are screwed to the edge of the intermediate plane 12 at the outwardly exposed there connection profile elements 16 of the outer frame modules.

In a second exemplary embodiment of a suspension crossbar 118, shown in FIGS. 5 to 7, those elements which are similar to those of the first exemplary embodiment described in FIGS. 1 to 4 are given the same reference numerals plus 100, so that with respect to the latter Description is made to the comments on the first embodiment reference. The second embodiment differs from the first in that no threaded rod 28 and therefore no gap 24 are provided as a receptacle for such. In addition, the suspension hook 122 is formed with an upper suspension area 122b and two lower connection areas 122a of a single plate (FIG. 5). Overall, the outer contours of the second suspension cross 118 substantially coincide with those of the first suspension cross 18. In the middle of the suspension area 122b of the suspension lug 122 is perpendicular to the surface of a continuous receiving bore 160 for a screw or locking pin, not shown, for connecting a known U-shaped bracket. The bracket is connected via a known Schraubspanneinrichtung with the lower end of the round rod, not shown in Figures 5 to 7.

Below the receiving bore 160 is a continuous, vertical slot 162 through which the carrier lug 120 passes and in which it is fixed centrally.

FIGS. 5 to 7 also show the suspension cross-side connecting bores 164.

The suspension cross 118 according to the second embodiment is symmetrical with respect to two mutually perpendicular planes of symmetry, which intersect in the axis of the round bar, not shown here, on which the Aufhängekreuz 118 is suspended. It is therefore particularly useful for mounting in the interior of an intermediate plane similar to that of Figure 2, where four frame modules abut each other, as viewed from above (Figure 7) has four substantially identical brackets for the corners of four abutting frame modules. A third embodiment of a suspension cross 218 is shown in FIGS. 8-10. Those elements which are similar to those of the second embodiment shown in FIGS. 5 to 7 are again provided with the same reference numerals plus 100, so that with respect to their description reference is made to the explanations concerning the second embodiment. In contrast to the second exemplary embodiment, only a single lower connection region 222a is provided on the hanging tab 222 in the third exemplary embodiment (FIGS. 8 and 10). The hanging tab 222 is therefore narrower on the side opposite the lower connecting region 222a, on the left in FIGS. 8 and 10, than on the other side. The carrier tab 220 is identical to that of the second embodiment.

Overall, the Aufhängekreuz 218 according to the third embodiment, only two brackets for two abutting frame modules, which are shown in the plan view in Figure 10 right above and below. It is therefore preferably used at the edge of an intermediate level, where only two frame modules collide, or at corners, where only one frame module to be hung on the Aufhängekreuz 218. The free, unnecessary side of Aufhängekreuzes 218, left in Figure 10, then projects only slightly beyond the edge of the intermediate level. There can then still each be placed another connection profile element as a conclusion, terminates with the outer edge of the narrow side of the suspension cross 218. The invention is not limited to steel construction supporting structures. Rather, other types of support structures, for example made of aluminum, plastic and / or a composite can be realized according to the invention. Instead of an overhead conveyor belt, the intermediate elevation 12 can also be used for other types of conveyor systems in which, in particular, rails, conveyor belts and / or cable ducts are to be arranged on the intermediate level 12. The frame modules 10 may also be suspended directly on the hall ceiling.

The intermediate plane 12 can also consist only of a single frame module 10 or of a multiplicity of frame modules 10 arranged next to one another.

The frame modules 10 can also be permanently connected to one another, for example welded or riveted to one another.

Instead of the round rods 30 and other types of traction means, such as chains or belts can be used.

Instead of Aufhängekreuze 18; 118; 218, other types of suspension devices connected to the carrier profile elements 14 and / or the connection profile elements 16 can also be used. It can also be used on both sides flat suspension devices, which can be fastened between two corners on edges of the frame modules 10, also clamped between two frame modules 10.

Instead of the T-shaped support body 38 and other types support facilities can be used. For example, the support body 38 instead of T-shaped and L-shaped, with the short arm of the L to the interior of the frame module 10 shows. Two such L-shaped support bodies 38 can be arranged between two frame modules 10 adjoining with their corresponding profile elements 14 or 16 in such a way that a total of a T-shape is formed.

The support body 38 may also be permanently connected to the frame modules 10.

The floor grid elements 50 and / or the side grid elements can instead of being detachably also fixedly connected, for example welded, to the frame modules 10. Instead of the screw or screws, other types of releasable fixative, such as brackets, can be used.

Instead of individual grid elements 50 may also be provided a continuous floor or side rails.
