EP1338726B1 - Flexible seating structure for multi-purposes use - Google Patents

Abstract

The spectator stand has one or more seating stand levels (1-3) mounted over each other at two or more pillars (4) and supports (10). The stand levels swing on one or more points, using fixed or adjustable pivot points (8). The seating stand levels are divided into several neighboring segments, which can swing individually and independently. In a layout of three seating stand levels, the upper and lower stands are shorter then the center stand. The stands are moved by a hydraulic (11) or pneumatic system, or by cables. The longer stand level can also be used as a stadium roof.

Description

The invention describes a flexible grandstand system for multivalent use in particular with rising from the inside out trusses for events of any kind, which require a flexible interior design and different space options and allow short changeover times.

There are a variety of different technical solutions known to adapt the different interior and space, especially in stadiums and other venues outdoors the desired needs. So z. B. from DE 100 45 906 OS a mobile collapsible grandstand known which is foldable, this solution is only suitable for small bleachers with a single bleacher level. This can be built at any point an interior with a limited number of seats, in the various events, as well as z. B. sporting events can take place, however, the possible space capacity is very limited. A similar solution is described in DE 29917917.

Several other solutions are designed for extendable grandstand seats. The individual rows of seats are driven among each other. For this purpose, a large number of individual movable elements are necessary. Although these technical solutions also offer the possibility of making the interior space and space variable and adapt for different uses, but are very costly and also suitable only for a bleacher level. Such similar solutions are for. B. in DE 36 30 704 PS and DE 197 55 515 OS described where horizontal telescopic stands are shown.

Even pluggable items that can be assembled into finished grandstands are known. However, the structure or conversion and change is associated with very high costs. For stationary systems such stands, as they are known from DE 35 19 718 PS, not suitable.

Stationary tribunes are from the sports complex z. B. for athletics stages and football stadiums. The requirements for football stadiums are great space for spectators and proximity of the first lower rows of grandstands to the edge of the field.

In athletics stadiums, the competition track (cinder track or tartan track) is still to be arranged between the spectators and the interior, the function room or the playing area. The required spectator capacity for athletic stadiums is also lower. For this reason, pure football stadiums and pure athletics stadiums are increasingly being built today in order to meet the corresponding requirements. The disadvantage is the limited use of such special stages. A multivalent use for different events is limited.

From the document JP 2-70 868 A, a solution is known in which in a hall three seating levels are designed to be pivotable and simultaneously liftable upwards. The goal is to make the entire floor area of a hall fully usable. Although it is thus possible to provide different space capacities available, but this solution is primarily suitable for indoor conditions and only partially applicable for stadiums. This can be seen in particular by the telescopically displaceable staircase-like accesses for the lower seat level shown in FIG. This solution is therefore only suitable for a relatively small number of spectators.

The DD 110 680 C describes a pivoting plane for multipurpose buildings, where in particular a pivoting parquet can be moved in a nearly vertical position by a stepped counterweight balance with the least possible expenditure of energy. It requires a relatively large amount of space for the necessary counterweight. This solution is also suitable only for small space capacities in halls. The aim of this invention is to obtain the most uniform possible continuous movement during pivoting and a constant drive power with low energy expenditure for generating the movement.

From GB A1 1 524 050 it is known to lift individual moveable grandstand levels at different heights and to build together from several grandstand-level parts an inclined single grandstand level of greater space capacity. The grandstand floor parts are collapsible so that they can be easily transported. They consist of a system of interconnected struts and supports in lightweight construction. However, these grandstand levels are designed for a small number of places and require both in construction and erection both a high manpower and time. Furthermore, they are not suitable for large stadiums for security-related concerns.

The FR A2 2 306 319 also describes a technical solution, where space requirements for individual einbige tribune parts can be stored to save space. They are designed so that they can be positioned and locked in different angles of attack, with each of the sitting or standing room can be easily aligned horizontally. In one embodiment, the erection is carried out via a fixed pivot point. This is a lightweight construction for only small space capacities. For large stadiums with thousands of seats this version is not suitable. The construction and dismantling is very time consuming and labor intensive.

The object of the invention is to provide a flexible grandstand system for multivalent use, which makes it possible to make the interior or the playing surface in dependence on the type of use in size variable to be able to use different tribune levels for use by spectators and thus a variable To provide space and at the same time to respond quickly and cost-effectively, based on different space requirements for different events.

The object is achieved by the features of the first claim. At one or more pillars 4 a plurality of bleacher levels 1 to 3 are arranged one above the other. The above a lower bleacher level 1 (the so-called base tribune) arranged further bleachers 2 (grandstand) and bleachers 3 (upper bleachers) are pivotally in two or more pillars 4, as is known one or more attachment points, the pivot points 8 are arranged. The pivot points 8 are fixed or adjustable arranged on the pillars 4 as needed. By the upper tribune levels 2 and 3 are designed to pivot upward, the lower bleacher level 1, the so-called base, which is usually permanently installed, made available. The audience can then follow the events inside without any obstructions. If the pivot points 8 are arranged on the pillars adjustable and in particular height-adjustable, the visibility of the base can be significantly improved. For three grandstand levels, the lower grandstand level 1 (base tribune) and the upper grandstand level 3 (upper grandstand) are shorter than the middle grandstand level 2 (main grandstand). At the pivotable bleacher levels 2 and 3, extensions are provided on the arrows 4 on the opposite side of the grandstands that extend the bleachers outward beyond the pillars 4. At the same time static counterweights are arranged on or in these extensions.

For static reasons, it makes sense, as is well known, to divide the entire length of the desired grandstands and thus the grandstands levels 1 to 3 in several adjacent segments (a grandstand length on the straights at an athletics stadium is after all over 100 meters), preferably individually and independently of each other are pivotable.

In general, the lower bleacher level 1 is stationary, d. H. firmly and immovably arranged. The two upper tribune levels 2 and 3 can optionally be designed to be movable and supportable via hydraulic elements and / or pneumatic elements.

In a particularly preferred embodiment, the upper tribune levels 2 and 3 are each pivotable by means of cables 5. The cables 5 are guided and supported by spreading carrier 6. These cantilever beams 6 are designed in the manner of crane arms, over which the cables 5 run and which absorb the forces during the pivoting movement and hold and secure the weight of the upper tribune levels in the upper pivoting position.

Furthermore, it is advantageous if these projecting beams 6 simultaneously form the roof structure and / or wear.

In another embodiment of the invention, the longest grandstand level 2 (grandstand) simultaneously forms the roof structure, d. H. It is weatherproof and equipped with means for the discharge of rainfall.

The roof structure can be extended advantageous if the the grandstand lining forming band 9 of the longest bleacher level 2 (grandstand) is pivotally mounted and the roof structure can be extended in the pivoted state in the interior. In addition, then the gangs advertising in this position is better readable from the grandstand seats.

The roof construction can be further extended into the interior, if in a particular embodiment of the invention on the longest bleacher level 2 (grandstand) extendable roof elements are arranged. These additional roof elements are. preferably arranged below the bleacher level 2.

The static counterweights are preferably formed, inter alia, by the staircases and supply rooms 12 arranged in the outer area.

Depending on the dimensions of the upper tribune levels 2 and 3, additional fixed and / or pivotally mounted supports 10 are attached to the upper tribune levels 2 and 3 for load transfer. With the swiveling version, a better view from the lower platform level 1, the base platform, is possible for the spectators.

In a preferred embodiment, the necessary lighting technology is arranged in the longest bleacher level 2, which can then be used when the grandstand is pivoted upwards.

In particular, in the preferred use as athletics and football stadium only two bleachers levels 1 and 2 are arranged one above the other. The grandstand level 2 (grandstand) spans in this case the grandstand level 1 (base tribune) and the adjoining competition course (cinder track or tartan track).

In a particular embodiment, the pivotable tribune levels 2 and 3 are guided between the pillars 4 and further extended beyond the pivot points 8 out. This makes it possible to arrange additional rows of seats and to increase the space capacity further. Furthermore, these other rows of seats act as counterweights.

In another embodiment, the tributaries, i. H. the supports carrying the stands also extend between the posts 4, extending beyond the pivot points 8. In this case, the tributary beams can be formed in the area beyond the pivot points themselves as counterweights. In general, the tribune support box profiles, z. B in their interior with fixed or movable counterweights, which then act as dynamic counterweights trained. Furthermore, additional additional dynamic counterweights can be attached to the stands.

The inventive arrangement of pivoting grandstands levels 1 to 3, it is possible to change the space capacity within a very short time and adapt the interior, in which the events take place, the respective needs. So it is z. B. conceivable to retrofit existing fixed bleachers an athletics stadium with the pivoting bleachers levels. Compared to a new building so considerable cost savings are possible. In this case, the competition course is covered by the grandstand and increases the space capacity accordingly. If necessary, the pivoting grandstand levels are pivoted upwards and the competition track can be used

According to claim 1 a plurality of bleachers 1 to 3 are arranged on several pillars. In Figure 1, the arrangement of three tribune levels 1 to 3 is shown in a first embodiment in cross section. It makes sense, the lower bleacher level 1, the so-called base 1, not pivotally formed, but permanently installed in the usual design. On pillar 4, which can also be formed by a solid wall construction and the outer shape can be designed arbitrarily, the pivoting central bleacher level 2 as a grandstand and the pivoting upper bleacher level 3 are rotatably mounted as upper tribune at pivot points 8. The upper tribune 3 is supported on the grandstand 2 by means of several supports 10. The supports 10 are arranged via pivot points for load dissipation. The grandstand 2 is supported by the supports 11 on specially designed foundations. These supports 11 are hydraulically actuated and formed in special versions telescopic. With them the grandstand 2 and the upper grandstand 3 can be swiveled upwards. In the extended state, ie when the supports 11 and 10 support the two tribune levels in an upper position, the base is freely available. The grandstand 2 is guided between the pillars and beyond the pillars 4, that is formed over the pivot points 8, extended. As a result, the space capacity is extended by additional rows of seats. In addition, this construction acts as a dynamic counterweight. Additional additional dynamic counterweights can be arranged on these extensions of the tributaries. As a result, the effort required for upward pivoting can be further reduced. The bleachers 1 to 3 are provided to the interior each with the bands 9.

In a further embodiment with reference to Figures 2 and 3, a preferred embodiment of the invention is shown. Figure 2 shows in cross section two superposed bleachers levels 1 and 2. The lower bleacher level 1, the base of the base is permanently installed. In addition, a pivotable bleacher level 2 is connected as the grandstand via pivot points 8 with the pillars 4. As conclusion of the tribune levels 1 and 2 bands 9 are arranged to the interior. The grandstand 2 is based on supports 10, which are either fixed or pivotally mounted on the grandstand from and take over the load protection in fully occupied grandstand 2. According to the invention on the pillars 4 extending carrier 6 in the direction of the interior and extensions 7 are arranged in the opposite direction , About this support 6 and the extensions 7, the cables 5 are guided and stored. The cables 5 may be attached to different parts of the grandstand 2. Here, an embodiment is shown where the cables 5 in the front area, ie the lower row of the grandstand are attached. In order for an unobstructed view of the interior is possible, the cables can be 5 attached aushängbar. They are then drawn to the deflection in the spreading carrier 6. If necessary, the cables are lowered 5, hung and by winding the cables 5, the grandstand 2 is pivoted up to a locking point. It is rotatably mounted in the pivot point 8. For reasons of space and to ensure a clear view from all points of the base 1, it makes sense to arrange the pivot point 8 height adjustable. If the pivot point 8 is displaced upwards on the pillars 4 by means of appropriate technical means, the main stand 2 can be moved upwards and locked up directly up to the projecting supports 6. This position of the grandstand 2 is shown in FIG. This is the Competition course (cinder track or tartan track) which extends directly to the band 9 of the base station 1 to the interior, including the base station 1 freely available and fully usable. The supports 10 are folded in Figure 3 to the grandstand 2 (not shown). Since the main grandstand has a considerable weight, 4 counterweights are arranged behind the pillars. As static counterweights preferably arranged in the outside area stairwells and supply rooms 12 are arranged.

The invention is particularly applicable to the multivalent use of a stadium for both football events, athletics events and other outdoor events.
