Denmark-Danmark (DK) * 4-77 / 7 ** (71) V. Reitz & Co., Vangedevej 106 B, 2820 Gentofte, Denmark-Danmark (DK) (72) Viggo Thorvald Reitz, Gentofte, Denmark-Danmark ( The present invention relates to a bubble hall consisting of webs of material attached to each other, and an inner layer, which are also connected to each other along the side webs and the end edges, the inner layer being provided with at least one air-permeable opening in each web of material.

The purpose of using the outer and inner layer is to provide better thermal insulation than if a simple layer is used. Thermal insulation is provided by the air ducts formed between the layers. Such air currents occur in known solutions in which the space between the inner layer and the outer layer is about 15 cm or more.

The object of the invention is to provide a bubble hall with effective thermal insulation. According to the invention, this is achieved in such a way that the outer layer in each web of material is so much narrower than the inner layer that a a sleeve protruding against the outer layer is fitted to the opening near the floor of the hall in the inner floor.

Compared to the prior art used in the invention, the small intermediate spaces formed between the inner and outer layers prevent the formation of convection flows on one side of the intermediate space, for example the outer side, and the simultaneous downward flow to the other side. However, in practice, the small size of the intermediate space often results in the outer and inner layers easily adhering to each other, which makes it difficult to fill the intermediate spaces with air. According to the invention, this problem is avoided in that the layers are already separated from each other by a sleeve.

Preferably, the inner wall of the sleeve has at least one through-bore in the space between the inner and outer fabric. This facilitates air penetration into the space between the layers, even if the outer opening of the sleeve is covered by the outer layer. The penetration of impurities and particulate matter into the intermediate space can be prevented by the side wall of the sleeve being formed by a net or the inner opening of the sleeve being provided with a net. The reticulated structure of the wall of the sleeve also facilitates the access of air to the space between the layers.

Embodiments of the invention will be explained in more detail below with reference to the drawing, in which:

Figure 1 shows a bubble hall according to the invention in cross section.

Fig. 2 shows a longitudinal section along the line A-A of Fig. 1 of a web-width fabric, partially dividing a longitudinal section in the longitudinal direction of two facing web widths.

Figure 3 is an enlarged cross-sectional detail B of the Bubble Hall shown in Figure 1.

Figure 1 shows a cross-section of the center of the hall, where the outer layer 1 and the inner layer 2 extend from one edge of the hall to the other between the two anchoring pieces 6a and 6b. As shown in Fig. 2, the web consists of an outer layer 1 and an inner layer 2.

In addition, Figure 2 shows the outer layers 1a and Ib and the inner layers 2a and 2b of the adjacent web sections. The inner layer 2 is connected to the respective edges of the inner layer 1 along the longitudinal edges 8 and 9 and the end edges 10 and 11, and the anchoring at the pieces 6a and 6b, for example by sewing, gluing or the like. In the case of the anchoring pieces 6a and 6b, the layers are fastened by means of longitudinally extending holders 5 which are anchored to the anchoring pieces, for example by means of an anchoring iron 7 (Fig. 3).

The inner layer has an opening 3 near the holder 5, into which a sleeve 4 projecting towards the outer layer 1 is inserted.

Prior to filling the hall, the inner and outer layers 1 and 2 have been pressed against each other in all the material webs forming the hall without any more substantial intermediate space. When the hall is filled, it rises while the inner and outer layers remain still close to each other. As the erection continues, air penetrates through the sleeve 4 in the hole 1 into the space between the inner and outer layers. Gradually the intermediate space reaches a thickness in which the wider web of these layers, i.e. the inner layer 2, which is at the same time most preferably made of a softer material, separates from the narrower layer 10, which is made of a stiffer and stronger material, and which acts as a bearing layer. layer 2 has tightened and possibly elongated in the longitudinal direction of the hall due to the overpressure in the hall.

The materials and dimensions of the layer have been chosen so that the thickness of the space is of the order of 2 cm, however, the average width of the space is about 1.5-2 cm.

The drawings show that the material tracks pass without bends over the center of the hall between the anchoring pieces 6a and 6b.

It is also possible to divide this web length into two sectors which join the central part of the hall, whereby at least one opening 3 provided with a sleeve 4 is arranged in each sector.

4,60585

The sleeve 4 is most preferably formed by at least one bore through the side wall of the sleeve in the space between the inner and outer layers, whereby both the erection and dismantling of the hall is facilitated. The pressure caused by the wind as well as the weight of the hall can otherwise cause the sleeve to be covered when the outer layer rests against the sleeve, making it completely difficult for air to pass through the sleeve.
