Heat-insulating air dome

Abstract

The air dome includes of one or several membrane shells made from textile-reinforced plastic film. These membrane shells are equipped on the entire surface of its underside with juxtaposed flat pockets which are heat-sealed on, bonded to, sewn on, or riveted on, each of which is designed to be open on one side, for inserting a multi-ply heat-reflective mat. Such mats are hybrid insulating mats having infrared-reflective metallized film or aluminum foils. Said mats can have multiple layers of absorption-reducing air bubble film to reduce the transmission heat losses. The openings of the pockets can be closed by means of a Velcro closure or zip fastener. A membrane is assembled from strip-shaped film webs, which are equipped along their longitudinal sides with a keder, and are connected with each other by connecting profiles in a force-locked manner.

         18 . The air dome according to  claim 15 , wherein the membrane strips are interconnected such that respectively the longitudinal edge of a membrane strip is connected to a keder, and an edge region of an adjacent membrane strip encloses this keder overlappingly, and one or several keder connecting profiles having a keder mount are pushed over the keder. 
     
     
         19 . The air dome according to  claim 15 , wherein the keder connecting profile having a keder mount profile has grooves on a side opposing the keder profile or in two side walls for hooking in objects like lighting fixture, nets, curtains, intermediate walls etc. 
     
     
         20 . The air dome according to  claim 15 , wherein the at least one membrane is equipped on the entire surface of the underside with juxtaposed airtight flat pockets which are heat-sealed on, bonded to, sewn on, or riveted on, each of which is designed to be open on one side, for inserting a multi-ply heat-reflective mat in the form of a hybrid insulating mat with infrared-reflecting metallized film or aluminum foils, wherein these openings each are closable almost airtight by means of a zip fastener or airtight by means of a heat-sealing. 
     
     
         21 . The air dome according to  claim 15 , wherein the membrane strips are perforated for the inside of the air dome to effect a sound refraction and thus to improve sound acoustics inside a hall. 
     
     
         22 . The air dome according to  claim 15 , wherein the film measures 3 to 5 meters in width and correspond in their length to the span of the air dome to be erected, so that a seamless roof membrane is created over its entire length. 
     
     
         23 . The air dome according to  claim 15 , further comprising 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 ETFE film is incorporated, for forming a window front. 
     
     
         24 . The air dome according to  claim 15 , further comprising on at least one longitudinal or transverse side of a frame construction with a frame profile along a strip foundation, at least one horizontal frame profile running thereabove having a groove on its upper side, for inserting a keder of a film web adjacent above, and a groove on its underside for inserting the keder at a transparent ETFE adjacent below, as well as having vertical frame profiles as braces, having grooves on both sides for inserting the keder into the lateral edges of the transparent ETFE film sections, as well as that on both end sides of the thus erected window front obliquely arranged supporting struts are built in, having sided grooves on both sides for inserting the keder of the internally adjacent window film and the externally adjacent film webs. 
     
     
         25 . The air dome according to  claim 15 , further comprising along the boundary of its floor plan on prefabricated, precast concrete strip foundations, which are embedded in sections in a trench surrounding the air dome and on whose upper side a Halfen profile with an upward opening is mounted, and in that anchor profiles having the keder of the membrane inserted into their receiving groove can be swiveled with their lower shoulders into the opening of this Halfen profile and can therein be hooked to its opening edges, for a force-locked connection of the membrane to the precast concrete strip foundation.
