Description

SPECIFICATION Demountable stand-type construction especially for temporary exhibitions The invention concerns a demountable standtype construction, especially for temporary exhibitions.

Temporary exhibition stands of hexagonal crosssection, are of interest, especially by virtue of their ease of access to visitors, the number and angular position of their lateral surfaces which form a similar number of exhibition surfaces which are visible from the outside over a large angle and also by virtue of the possibility of juxtaposing several identical stands by incorporating them within one another so as to construct an exhibition structure of large size.

However, the formation of these constructions presents substantial technical problems when the constructions are to be temporary, because the requirements for robustness and rapidity of assembly and disassembly are then to the forefront.

The present invention has a particular object of overcoming these disadvantages and in this respect concerns a demountable construction of the stand type, especially for temporary exhibitions, comprising a roofing framework in the form of regular hexagons which receive respectively flooring panels and roofing elements of corresponding form, poles for holding up the roof framework, these poles being supported by the angles of the regular hexagon forming the framework of the ceiling, the construction being characterised in that the flooring framework comprises twelve brams of equal length which define the six sides of the hexagonal flooring framework in the form of regular hexagons which receive respectively flooring panels and roofing elemtns of corresponding form, poles for holding up the roof framework, hese poles being supported by the angles of he regular hexagon forming the framework of the ceiling, the construction being characterised in that the flooring framework comprises twelve beams of equal length which define the six sides of the hexagonal flooring framework and six radii of the circle circumscribing this hexagon and connecting its centre ti its angles, these beams being fixed rigidly at their ends to polygonal sleeves, these sleeves having at their base a level-controlling screw jack.

According to another characteristic of the invention, the polygonal sleeve positioned at the centre of the flooring framework is a regular hexagonal prism, the polygonal sleeves at the angles of the flooring framework being formed by prisms having an irregular pentagonal cross-section of which three adjacent sides are of the same length and form angles of 120 with one another, the two other sides being of identical breadth and together forming an angle of 120 .

According to another characteristic of the invention, the beams have a width corresponding to the width of the sides of the sleeves on which they are rigidly connected.

According to another characteristic of the invention, the roofing framework is extended beyond the flooring framework, rectangular and euqilateral triangular flooring elements being arranged respectively along the side beams and at the height of the angles adjacent to the flooring framework, of several stands assembled together by the sides of their roofing frameworks.

According to another characteristic of the invention, for the juxtaposition of several stands, a common pole is provided within the adjacent angles of several stands, this pole being formed by a tube which opens out at its upper end into a collecting vessel for rainwater, into which guttering disposed along the lower edges of the roofing elements of adjacent stands drains, this vessel being also provided with means for holding up the roofing framework of adjacent stands.

The invention is illustrated by way of nonlimiting example in the attached drawings, in which: Figure 1 is a perspective view of a stand in accordance with the invention; Figure 2 is a schematic axial cross-section of the stand of Figure 1; Figure 3 is a schematic diagram showing in elevation the construction of the flooring framework; Figure 4 is an exploded view showing the assembly of flooring beams together by means of sleeves; Figure 5 is a detail view of Figure 1; Figure 6 is an axial section showing the assembly together of flooring panels in the flooring structure; Figure 7 shows as a partial lateral view the connection of two adjacent stands; Figure 8 is a schematic plan view of the assembly together of three adjacent stands; Figure 9 is a lateral view showing means of recovering drainage away of rainwater between two adjacent stands;; Figure 10 is a section along A-A of Figure 9; Figure 11 is a plan view of a demountable construction obtained from several juxtaposed stands in accordance with the present invention; Figure 1 2 is a detail view of the assembly of the base of a pole at the floor.

The object of the present invention is therefore the construction of a demountable stand of hexagonal cross-section which can be rapidly erected and taken down, and which is robust.

In the attached drawings, there has thus been shown a stand which comprises a floor 1 arranged resting on a flooring framework 2 and roofing elements 3 rigidly fixed to a roofing framework provided with radial beams 4.

The framework of the roof is supported by the framework of the floor via vertical beams or poles 5 arranged within the angles of the hexagonal floor framework. The framework of the roof 4 supporting the roofing elements 3 extends beyond the flooring framework (Figure 2) and it includes a belt 6 of which the various parts from bands fixed between the poles 5.

These elements 3 can be formed by isosceles triangles of a rigid material which can be juxtaposed, or a single pyramid-shaped covering element.

Furthermore this flooring framework includes a polygonal central sleeve 9 which is connected to the angle sleeves 8 by beams 10 which define, together with the beams 7, a construction which includes six equilateral triangles adjacent to one another.

Also, so that the flooring panels can be effectively supported by the framework 2, the radial beams 10 connecting the central sleeve 9 to the angle sleeves 8 are rigidly fixed, mid- way along their length, to beams 11 which are thus parallel to the side beams 7, beams 1 2 being perpendicularly fixed between the midpoints of these beams 11 and the midpoints of the side beams 7.

The central sleeve 9 is in the form of a casing of regular hexagonal cross-section (see Figure 4), the case of which includes a screw jack 91 which permits adjustment of the level of the radial beams 10.

Furthermore, the angle sleeves 8 are in the form of a casing of irreguiar pentagonal cross section of which three of the sides 81 and 82 and 82 are of the same width and together form angles of 120 whilst the two other sides 84 and 85 are also of the same length and form between them an angle of 120 so as to be in alignment with the side beams 7.

The base of each sleeve 8 also includes a screw jack 6 which permits adjustment of the level of the beams 7 and 10.

The rigid connection of the beams 7 and 10 on the polygonal sleeves 8 and 9 is achieved by hooks 1 3 welded to the ends of the beams and engaging in orifices of corresponding cross-section 14 formed on the walls of the sleeves.

Preferably, the beams 1 3 are of a height and a width which corresponds to the width and the height of the faces of the sleeves 8 and 9 on which they become engaged.

The rigid positioning of the beams 11 between two adjacent beams 10 and beams 1 2 between beams 11 and beams 7 is obtained (see Figure 5) by providing at the end of these beams 11 and 1 2 end feet 1 5 having orifices which receive teats provided on the corresponding beams.

The floor 1 resting on the framework 2 will be formed with the aid of 1 2 right-angled triangular panels 16, each of which forms a half of one of the equilateral triangles defined by the beams 7 and 10, so that the hypoteneuse of each panel rests over its whole length on the length of a radial beam 10.

These panels 10 which are, for example, formed of plywood, are reversable and are edged by metal runners 1 7 (see Figure 6) provided with regularlyspaced perforations which permit the fixing of these panels to teats welded to the upper surfaces of the profiles 7, 10, 11 and 12. So as to prevent the twelve adjacent points of these panels 1 6 which are situated above the sleeve 9 from becoming displaced relative to one another in the vertical direction (see Fig. 6), all of these points are covered with a plate 1 8 which is locked by means of a screw 1 9 in a threaded orifice provided on a plate 92 closing off the top of the sleeve 9.

The framework 4 of the roof constitutes, together with the covering elements 3, a pyramid with a regular hexagonal base, the periphery of which extends beyond the flooring framework 2. The invention however permits the juxtaposition of several of these hexagonal stands by arranging the sides 3, of the roofing elements 3 side by side (see Fig. 7) and by filling the space formed between the flooring elements 1 of adjacent stands. This arrangement is obtained (see Fig. 8) by rigidly fixing the beams 20 on the faces 84 and 85 of the angle sleeves 8 (Fig.4) so as to perpendicularly connect the side beams 7 of three adjacent stands 21, 22, 23 in pairs.

The space formed between the floors of these three stands is then filled by rectangular panels 24 having a length which corresponds to that of one side beam 7 and by equilateral triangular panels 25 located in the angles of the adjacent stands. These panels 24 and 25 will rest on and be positioned on the side beams 7 and the connecting beams 20.

Given the possibility of juxtaposing stands as is shown in Figure 11, means are also provided which permit collection of the rain water which drains along the lower edges 3, of the roofing elements, these edges 3, being arranged within the stand assembly formed.

Thus, it is provided to traverse the triangular floor element 25 with a tube 26 which includes at its upper end a vessel 27 into which the three gutters 28 drain, each of which is arranged beneath the two adjacent edges 3, of the roofing elements of two adjacent stands. Thus, the water which drains from the roofing elements 3 within the stand assembly runs into the gutters 28 then into the vessel 27 and finally escapes beneath the stands through the tube 26.

In the interior of the assembly of several stands, the three poles 5 which hold up the roof framework can usefully be dispensed with as is shown in Figs. 9 and 10. Thus, in this case, the watercollecting vessel 27 is formed as a triangular casing which is provided at its tops with feet 27, on which the framework elements of the roofing framework can engage. The tubes 26 provided with their casing 27 and the feet 271 then form the element which replaces the three poles 5 supporting the three adjacent stands.

Finally in order to reduce the raising efforts owing to the effects of depression by bad weather, there is provided (Fig. 12) a tubular sleeve 30 bolted into a threaded hole 86 at the centre of each prismatic box 8 of pentagonal cross-section, in other words to the centre of the base of each pole 5. A bolt 31 fixes the poles 5 to the floor framework by means of the sleeve 30. An angle-iron 32 acts as a blocking piece for the sleeve 30 and the vertical end.
