Definitions

  • Air domes offer compelling advantages for various applications, for example as roofing for outdoor pools, as tennis halls, warehouses, commercial halls and temporary halls for events of all kinds. They consist of a dome-shaped cover from a textile-reinforced plastic membrane, which is anchored to the ground at its edges and sealed there against the spanned interior. Using air blowers, an overpressure compared to the atmosphere is generated inside which inflates the membrane and holds it stable in this position. For this, only a small and not noticeable pressure difference to the atmosphere is necessary, because only the membrane weight and any wind and snow loads have to be carried. This usually corresponds to a load of approx. 25 to 35 kg/m 2 .
  • the entrances are designed with sealing 4-leaf revolving doors or pass-throughs.
  • the outer shell usually consists of a fabric-reinforced plastic membrane of the highest quality, usually light-transmissive.
  • the outer shell is the actual static membrane, which has to bears wind and snow loads and is impregnated against UV radiation and soiling.
  • the single- to multi-ply intermediate layers having enclosed air pockets are incorporated primarily as insulating layers. They are to improve the heat transition coefficient of the hall in direction of the insulation.
  • the innermost membrane forms the end of the two- to multi-ply air covers. It is executed in white for light reflection.
  • a darker color e.g. green or blue
  • a height of at least 3 m so that the tennis balls are more easily recognizable to the tennis players.
  • air domes are subject to a special DIN standard. In contrast to a fixed structure, they can readily be dismantled and set up elsewhere if required.
  • the heating costs account for approx. 1 ⁇ 6 of the construction costs, i.e. they amounted to 81,000 Swiss francs for the winter 2004/2005 and 86,000 Swiss francs for the winter 2005/2006.
  • With a 2 ⁇ 2-layer membrane it should be possible to reduce the heat requirement, and thus the costs for natural gas, by approx. 30%.
  • a decisive structural part is the film of the air dome.
  • the roof can be constructed with 2 ⁇ 2 membranes, which results in a U-value of about 1.1 W/m 2 K.
  • 2-layer membrane roofs with a significantly lower U-value (3-layer approx. 1.9 W/m 2 K).
  • the additional price for the best construction is definitely reasonable in view of the high follow-up costs due to the energy consumption.
  • a certain transmissivity of the film to solar radiation is to be rated positively.
  • the total energy transfer ratio amounts to approximately 0.1 (0.07 to 0.2).
  • the object of the present invention is to flood such an air dome at least partially with daylight in order to create an ambience, and atmospheric and visible connection to the outside world inside the air dome.
  • a further object of the invention is to improve the acoustics within the air dome and thus provide a more pleasant atmosphere.
  • Yet a further object is to specify such an air dome having daylight inside, which can be erected more quickly and with far less personnel than hitherto, and which, if necessary, can be dismantled just as quickly and easily, and is easy to transport and put into interim storage.
  • the fourth object of this invention is to improve the acoustics within the air dome and thus provide a more pleasant atmosphere.
  • an air dome having one or several membrane shells from plastic film material, characterized in that it has on at least one longitudinal or transverse side a frame construction which is connected to the bordering membrane material, and in the frame profile at least one transparent or translucent film or a firm or bendable plate is incorporated, for forming a window front.

  • the membrane to be supported by means of air pressure is firmly and airtightly interconnected by heat-sealing, from several membrane strips overlapping at the edge to form a 2- to 3-part membrane.
  • the 2 to 3 membrane parts are screwed together by means of clamping plates.
  • the screwed-together membrane is then connected with its edge all around with foundations or ground anchors.
  • This membrane of a conventional air dome thus forms a continuous, smooth surface inside and outside, and it is not possible to attach anything to it on the inside, except by means of a bonding. This also makes the applying of conventional thermal insulation impossible.
  • the air domes according to the invention have in all embodiments a very special equipment for retaining its heat inside the air dome.
  • Their films or membranes are provided with a heat-reflective material for thermal building insulation.
  • this heat-reflective material is inserted in the form of mats, which are cut from a roll, on the inside of the membrane, for example in flat pockets arranged like a matrix, which are heat-sealed onto the membrane.
  • the pockets are closed, for example by means of a Velcro fastener or a zip fastener. Thereby the entire membrane is covered by these heat-reflective mats which are hidden in the pockets.
  • the membranes are at the same time constructed in a novel way in comparison to that of the conventional air domes, namely from several membrane strips which are linked together along their longitudinal sides by means of keders and keder connecting profiles into a complete membrane. Firstly, this is faster, requires far less personnel and offers the advantage that the membrane can again be easily dismantled, so that the air dome can be dismantled, moved and reassembled elsewhere much more easily.
  • the individual film webs are equipped with special pockets for insertion, as will be shown and explained later.
  • an individual membrane strip 8 is represented, in a position as if it were installed in a hall membrane. Thus it extends from the ground over the zenith of the hall to the ground on the other side. It therefore measures, for example, 42 meters in length if it is to span a tennis court lengthwise. Its width measures approx. 3 to 5 meters, depending on the implementation. It is executed two-ply and thereby forms a pocket. Into this bag a heat-reflective mat is inserted such as will be described later. Such mats are roll material, which is available in widths of 2.5 meters, for example, having a thickness of approx. 25 mm.
  • a strip of 2.5 m ⁇ 42 m length can be inserted into the pocket of a membrane strip, or two such heat-reflective mats overlapping slightly along their longitudinal edge can be inserted in the pocket of said membrane strip over its entire length.
  • the two-ply membrane strip is heat-sealed on three sides, and one longitudinal side is initially left open so that a pocket is formed. This allows the inserting of a strip of heat-reflective film over the entire length of the membrane strip. Afterwards, the opening of the pocket in the membrane strip is heat-sealed, so that the membrane strip is tightly sealed all around, and then several membrane strips are joined together by means of connecting profiles with the keders present along their edges.
  • FIG. 3 shows a cross-section at position A-A of the membrane strips 8 , from which one recognizes that an overlap of the two strips 8 is produced along their longitudinal edge, so that always a heat-reflective film extends continuously over the assembled membrane strips between the inner side and the outer side.
  • FIG. 3 shows that a keder 5 having a film section 6 is heat-sealed onto the membrane strip 8 , here on the left.
  • the membrane strip 8 on the right rests with its longitudinal edge over the longitudinal edge of the left membrane strip 8 . Its edge ends in a section 7 , which is guided over the keder 5 and around it.

  • On the inside of the two membrane strips 8 one can recognize the heat-reflective mats 13 . These mutually overlap slightly, although they are inserted in different pockets. However, this creates a continuous heat-reflective layer across the connection of the two membrane strips 8 and the forming of a cold bridge or heat bridge is thus prevented.
  • the membrane strip 8 directly forms the outer membrane, made from a material as conventionally used for the requirements of an outer membrane, and weighs about 1 kg/m 2 , and the inner membrane could in principle be made thinner.
  • FIG. 4 basically shows the same thing, except that the keder is directed downward, i.e. toward the interior of the hall, and the connecting profiles are attached to the underside of the inner membrane.
  • These profiles can be specially designed with a groove on their lower side, in which, for example, lighting fixtures, nets, partitions, curtains etc. can be suspended.
  • the inner membranes are perforated, whereby an efficient sound insulation is achieved. The sound, as it is generated in tennis halls by hitting the balls, or the sound in swimming pools where it is regularly loud, is effectively refracted on the perforated inner membrane and a far more pleasant sound climate is achieved.
  • FIG. 5 shows the section along the line B-B in FIG. 2 .
  • the two-ply membrane strip 8 is joined at the lower section directed toward the ground and thus ends in a flat flap 24 . This is then folded down on the inside of the hall and rests on the floor.
  • a keder 5 heat-sealed thereupon. This serves for connecting to the ground. It is inserted into a profile which forms an anchor rail on a strip foundation.
  • FIG. 6 shows an overlap in perspective representation.
  • the membrane strip 8 on the left in the picture, overlaps the membrane strip 8 , on the right side of the picture.
  • This right membrane strip ends in a single-layer film, which is guided over the keder 5 and covers it fully and extends slightly further beyond the keder 5 .
  • a connecting profile can be pushed over the keder 5 .
  • FIG. 7 shows a schematic representation of a number of membrane strips 8 , which are arranged next to each other. In a tennis hall, for example, they extend advantageously along the tennis courts and thus span these transversely to the direction of the tennis nets on the playing courts.

  • a two-ply film 8 is unstitched along its edge into two flaps 7 , which enclose the extension 6 from both sides and are firmly heat-sealed to it. Thereby a force-locked connection is created between the keder 5 and the film web 8 .
  • the edge of a film web 8 can also be heat-sealed onto the only one side of the extension 6 , wherein the introduction of force is then not completely symmetrical.
  • a circular rubber profile 11 can be used as a keder 5 , which is surrounded by a film 10 , wherein the film 10 then ends in two edge sections 9 , as shown in FIG. 10 .
  • These two edge sections 9 can receive on both sides a film web 8 having their pocket 12 along its longitudinal edge between them, and they are firmly attached to the film web 8 on both sides by heat-sealing to the edge region of the film web 8 . In this way too a force-locked connection is generated transversely to the keder 5 .
  • FIG. 11 shows a possibility of a connection of two adjacent film webs 8 , whose longitudinal edges are each equipped with a keder 5 .
  • the connecting profiles 1 are pushed one by one over their keder 5 in the longitudinal direction to the film webs 8 .

  • the slots between the successive connecting profiles 1 can be closed with an elastic sealing compound.
  • the longest possible connecting profile sections are used. For greater lengths of several meters, depending on the wall thickness of the profiles, they are bendable by a radius that allows an entire membrane dome to be created from one side to the other with only a few profile sections.
  • Such a film web 8 of a tennis hall which spans the courts in the longitudinal direction, is approx. 42 m long.
  • a few easily transportable connecting profile sections are sufficient, for example 3 ⁇ 14 m long sections, or 4 ⁇ 10.5 m or 6 ⁇ 7 m long sections.

  • the individual connecting profiles 1 measure, for example, approx. 30 to 50 cm and can therefore be pushed on by a single assembler. Electively, longer profile sections can also be used, up to a maximally transportable length.
  • FIG. 13 shows a cross-section of a tennis hall.
  • the film webs 8 run transversely to the viewing direction and extend upward from the ground, over the zenith of the ridge to the other side and from there back to the ground.

If they are delivered in shorter sections, they can be force-lockingly and tightly heat-sealed together in a conventional way at the construction site by a slight overlap of a few centimeters in order to achieve the necessary length.
  • These film webs 8 are now equipped with pockets 12 as a special feature. These pockets 12 extend over the width of the film webs 8 between the keders 5 , i.e.
  • the pockets are approximately 3 m to 5 m wide, and they are slightly broader than 1.5 m to 2.5 m, so that after inserting a mat 1.5 m or 2.5 m wide, an edge is formed, which remains free and can be fitted on the open side of the pockets with Velcro fasteners on the inside.
