Grandstands are used in many types of event spaces, especially at competitive events on sports fields, in the circus, for open-air theater performances and the like. Needed in a variety of ways. Either they are fixed into the slope or as fixed ones Building erected. Pur certain, repeatedly assembled and disassembled, staggered rows of seats, such as In circus tents or the like., Special support structures are known.

The various scaffolding systems are known from the field of scaffolding technology, including that of so-called 'all-round scaffolding' originating from the applicant i.a. according to DE-PS 24 49 124.

Such scaffolds consist of vertical tubular supports as stems and horizontal and diagonal connecting and support elements and / or frames and bracing elements as well as connection and coupling elements, Compensating parts and the like. So far, they have only become very thin frameworks as scaffolding with a depth between about 50 cm and about 1.50 m erected either on building walls and towers or as supporting elements for temporary hall constructions with tent covers or the like .. You can thanks to the highly developed Technology can be set up and dismantled quickly. A variety of sensibly arranged plug-in elements are used for this purpose. With such scaffolding elements, no grandstand support structures directly supporting the seats have so far been possible build up because there are suitable adjustment elements for the stepped support of gangplanks and Benches as well as the necessary stairs to be arranged in between and, if necessary, railings to be attached outside are missing.

The invention is based on the object of proposing a support structure of the type mentioned at the beginning, using as many load-bearing elements as possible, standardized for scaffolding and a few special additional elements quickly and reliably assembled and quickly restored can be dismantled. According to the invention it is provided that the supports and the horizontal and diagonal connection and supporting elements of scaffolding standards and / or scaffolding frames, horizontal girders, horizontal ledgers, straight bars, Couplings and the like. A conventional scaffolding system are formed and that for the stepped support of Stepped walkways and seats with connecting elements that are matched to the scaffolding system Cheek parts are provided in which the lower and upper connections of the supports and horizontal distances the supports correspond to the grid dimensions of the scaffolding system.

By the proposal according to the invention, the existing By combining elements with a special cheek element, it is now possible in a simple manner to create complete stands to be built according to the scaffolding system and to design and plan your supporting structure accordingly and put together. You can use a variety of standards, diagonal struts, horizontal struts, scaffolding frames Use connection and coupling elements from the standard range and essentially only require a suitable one Side wall element, which is matched to the usual gangplanks and according to the basic grid system is divided accordingly. Since the basic grid size varies from scaffolding system to scaffolding system,

within certain limits also the dimensions of the cheek part be designed with adaptation to the needs, namely the seat height and the incline. Naturally, the desired bench seats or individual seat support elements and, if necessary, Railing elements "are required, which can be manufactured using conventional technology. The design of the Cheek parts can be done in different ways and is the respective scaffolding system, for example the support of the gangplanks, their width and the like. Adapt. If necessary, are for stiffening provide corresponding connection elements. Such a cheek part can then be produced in large numbers as a similar element of the entire stand structure can be used again and again if it is coordinated with the other basic elements of the scaffolding system is. On the cheek part, a variety of different from the usual framework material can be used Parts are provided directly or attached with suitable connecting means. So can through the design of the cheek part 'and a few other additional parts with the same material rational support structures for Grandstands of many types and the smallest and largest dimensions can be created according to the modular system.

A particularly advantageous embodiment of the cheek part looks between two vertical pieces of pipe according to the incline of the grandstand, the height of the horizontal girders is spaced apart and a horizontal beam connecting them approximately in the middle Vertical connecting element in front. By combining two rows of seats and two rows of gangplanks for the feet with one cheek unit each, you can use a grid system of around 1.5 m Fit the field size very well with a gradient of approx. 0.25 m and a cheek element height of approx. 0.5 m. The cheek part is then also inexpensive to manufacture, easy to store and transport, as well as

easy and practical to assemble. At this size it can also be the necessary with usable dimensions Maintain stability and allow the attachment of the necessary connection elements according to the respective Purpose of use. In detail, it can be constructed and designed in many ways, depending on which Materials you use, combine if necessary, which subdivision into production sections you make, how to connect seats and gangplanks and how to connect to the other scaffolding elements.

It is expedient to see that the lower pipe section assigned to the lower horizontal support is at the bottom has a stem connection and extends up to a seat support, and that the upper horizontal support associated upper pipe section has a stem connection above and below. So you can do it each time upper cheek part on its lower pipe section over the handle connection with the handle connection of the Simply connect and support the upper end of the upper pipe section of the respective cheek part below in each case at the lower ends of the upper pipe sections with suitable conventional scaffolding elements down to the floor and in this lower support area the usual scaffolding tubes or scaffolding frames with longitudinal, transverse and diagonal connections as well as height adjustment elements to compensate for uneven floors. Of the a seat support thus already has a natural support necessary for the connection to the support. Of the further seat supports for the second row of seats to be provided for each side bolster are expediently formed in such a way that that a seat support projecting upwards over the upper horizontal support is provided in the central area is. One seat support is provided above the support to the floor, while the other Seat support of each cheek element in the middle between over

L 48.2 DE 12

the correspondingly stable cheek part is provided. The arrangement discussed here sees two Rows of seats with two rows of gangplanks each and two seats for each cheek element. One can naturally also a corresponding cheek part for each row or for three and possibly with a correspondingly stable construction also provide cheek pieces for four rows. The training for every two rows seems to be of the size, to be the cheapest solution in terms of material usage, production and assembly.

The seat supports expediently have engagement elements for at least one bench seat. These can be in In the form of protruding pins, in the form of bores for the engagement of pins or claws, but also In the form of slots, bends, claws or the like. Be formed. Depending on whether you have the end supports wants to form bench seats differently than intermediate supports, can you have different seat supports for the support of a bench or for the common Provide support for two bench seats. It is advisable to choose the double support and, if necessary, the one in the end area Cover the remaining seat support part appropriately.

The cheek piece with its various components can be produced in different technologies, for example at least z. T. from non-cutting shaped elements, possibly forged parts or from high quality Casting existing parts. In view of the general use of semi-finished products in scaffolding technology However, it seems particularly appropriate that pipe pieces, seat supports, horizontal supports and vertical connecting part of semi-finished steel sections are formed and welded together. With appropriate processing machines and processing technologies, the cheek parts can be inexpensive

are manufactured. The pipe sections can be conveniently welded on the front side in front of the horizontal girder. In the configuration for two rows of seats, the upper pipe section expediently has a length equal to the two Slopes of the horizontal girders for the gangplanks or the seat girders and both pipe pieces expediently end at the bottom of the same level. They are then equipped with suitable connection elements for To equip the scaffolding system, however, no additional parts are required for compensation for each cheek element of height differences. In the case of a particularly expedient to manufacture and to assemble quickly and configuration to be dismantled, both pipe sections are cut off smoothly at the bottom. The upper piece of pipe then has a holding and centering pin corresponding to the inner diameter at the top. This is for scaffolding systems expedient, the tubes simply plugged onto one another with holding and centering pins on the inside of the connection exhibit.

For the middle seat support you can see in the middle area of the cheek part on the upper one Horizontal support a vertical seat support tube which is welded on and its upper end has the seat support. This seat support tube can also be used for the connection of further elements will. The horizontal girders are expediently designed as upright rectangular tubular elements, on which upwardly open U-profiles are welded, in the legs of which the claws of gangplanks can be hung are. You can then use additional protection against withdrawal Simply insert the usual design for securing the gangplanks. For further reinforcement and the railing connection can the seat support tubes transversely to the cheek plane standing flanges for the connection of under the

Cross braces and / or handrails to be provided for benches exhibit. Such cross bracing can be screwed to the frame or from the frame Diagonal bars and the like. Be formed.

A grandstand also requires a stairway area with appropriate steps in the manner of a staircase. Depending on the slope of the grandstand and the depth of the gangplank, there may be steps in the climbing area unfavorable performance conditions. With a slope of, for example, 25 cm and a gangplank depth of about 60 cm, there would be an unfavorable ratio, especially for mass events. That is why you can see special stair step elements that are placed, supported and fastened in the appropriate places. For this, an advantageous embodiment provides that for the formation of stairs between the rows of seats Step parts are provided which each have a gangplank element with supports and / or to adjacent ones Have support arms reaching support parts. These can provide in one embodiment that the Step parts are designed as intermediate step parts, which together with gangplanks suspended by means of claws Form the stairs and rest on a gangway with one support each and with two each Equipped with holding arms reaching to adjacent seat support tubes with couplings that can be connected to them are. Such a configuration requires the application of the couplings, but secures a special one stable connection. Another one, simpler in design and, in most cases, also more safe to walk through and cheaper to assemble and dismantle design provides that the stairs alternate arranged gangplanks is formed with claws and stair parts lying approximately in their plane, wherein the stair parts engaging in spaced U-profiles,

have claws arranged on holding arms. The holding arms are from the actual tread area To be provided alternately protruding above and below, so that they fit into the U-profiles and keep the tread at a suitable distance. Such elements only need to be hooked in and can be firmly attached to the U-profiles with the usual lift-off protection will.

Special attention should be paid to the design of the railing for stands that do not extend to the walls because they have to absorb considerable loads and must be absolutely safe. You are accordingly to be stable and to be firmly attached to the grandstand. For this you can see appropriately at the Stringer parts in front of railing fastening holes, on which the railing rods or additional railing elements can be attached. You can see especially for the railings on the back and their attachment expediently special railing fastening elements, which can be plugged onto retaining and centering pins Have pieces of pipe and railing mounting flanges attached thereto, with railing mounting holes in the paddles are to be provided. Corresponding railing elements built using conventional technology can then be connected easily and reliably.
