Definitions

  • Weather protection device composed of elements and attachable to scaffolding
  • the invention relates to a weather protection device composed of elements and attachable to a scaffolding, the element consisting of a first tarpaulin which can be fastened to horizontal and / or vertical struts of a scaffolding, and a second, outer tarpaulin arranged at a distance from the first, inner tarpaulin , wherein the inner and the outer tarpaulin are connected to one another in such a way that a space is obtained which is essentially airtightly enclosed by the tarpaulins, the space being laterally connected to an air supply device which generates an overpressure within the space.
  • Such a weather protection device is already known from WO 98/13564, see in particular its claim 15.
  • GB 2287728 A Furthermore, reference is made to GB 2287728 A.
  • the weather protection device according to GB 2287728 A is used to cover the roof surface of a building in order to protect the work place from the weather during processing.
  • WO 98/13564 is essentially about protecting vertical work areas, that is to say the wall surfaces of buildings.
  • the object of the present invention is to provide precise information on how this connection can be created in the cheapest way.
  • connection is to be provided in such a way that it can be easily manufactured and removed again, is able to cope with the rough operation at a construction site and meets the special requirements which arise from the fact that it is a flexible material from which the elements are made.
  • the air supply device consists of a piece of tubing, preferably a rectangular cross-section formed between the adjacent side tarpaulins of two adjacent elements, which consists of a material with properties similar to those of the tarpaulins.
  • the piece of hose ensures that the adjoining walls can move towards and away from one another, as is necessary for the bulge of the element produced by the air pressure.
  • the fact that the piece of tubing has a certain length makes it possible in particular to compensate for the increases in distance between adjacent side tarpaulins of adjacent elements that are produced during inflation. In addition, accessibility is improved and assembly is thus simplified.
  • At least one end of the tube piece is designed such that it can be connected to the edge of an opening in the adjacent side wall of another element in an essentially airtight manner.
  • This facilitates assembly and is particularly well suited to the adjacent ones Elements to maintain their entered mobility and thereby prevent tension and unnecessary loads on the tarpaulin material during inflation and in the operating position, so that on the one hand the material is not unnecessarily stressed, but on the other hand no leaks at the otherwise easily resulting from tension Connection points occur or are enlarged.
  • the other end of the tube piece is inseparably connected to the edge of an opening in the adjacent side wall of the one element, such as sewn, glued or integrally formed with it.
  • the production is simplified, on the other hand, the tightness is increased, and, on the other hand, assembly and disassembly are made easier.
  • At least two opposite walls of the preferably four walls forming the tube piece have been created by making a central longitudinal section in the element side wall to form a rectangular opening for the tube piece and a cross section at each end and the two tabs that form folded out and connected to two transverse walls assigned perpendicular to them. This eliminates the need for sewing or gluing in this area.
  • one end of the tube piece is connected to the edge of an opening in the adjacent side wall of the one element by means of push-button devices.
  • pushbutton devices are particularly well suited because they are insensitive to dirt and have sufficient strength, as well as a secure connection, even when they are repeatedly opened and closed, the existence of which is also easily controllable.
  • an element is constructed in such a way that an opening is provided on one side wall with female / male push-button parts attached to the outer edges of the edges, while a piece of hose is attached to the closest and / or opposite wall which has matching female / male push button parts at its end.
  • the arrangement allows great variability in the use of the element in an arrangement consisting of several elements.
  • the air flow to and through the individual elements can be adapted to the respective needs.
  • the connecting lines between the lateral tarpaulins of an element and their inner and / or outer tarpaulin can form a thickened cross section which can be inserted into a correspondingly undercut groove in a piping rod.
  • An adjacent element can then be correspondingly anchored in a second groove of such a lattice rod, so that individual elements can thereby be laterally connected to one another without creating gaps, the undesired access of outside air to the inner area where the work surface is located, takes place.
  • the piece of tubing has a rectangular cross section with a longitudinal extension / transverse extension which is only slightly smaller than the length / width of the associated side wall of the element. In this way, the flow resistance between two adjacent elements is reduced.
  • an opening that is not used can be closed by a flexible cover device, optionally buttonable.
  • a flexible cover device optionally buttonable. This has the advantage that elements originally intended as die-cast elements can also be used as end elements. This reduces the number of different element shapes required for the effort of an overall protective device.
  • the inner tarpaulin of an element can have valve devices in order, as in the prior art, to supply a work surface with additional (warm) air.
  • valve devices in order, as in the prior art, to supply a work surface with additional (warm) air.
  • elements without such valve devices can be used, or they are elements that are equipped with closable valve devices.
  • Lockable valve devices of this type can, for example, simply consist of a small round opening which can be closed by means of a sewn-on flap which ensures their closed position by means of Velcro devices.
  • a push button device or a hook device or a zipper can also be provided.
  • Fig. 1 schematically shows a composed of several elements
  • Weather protection device attachable to scaffolding
  • FIG. 2 shows a cross-sectional view of two adjacent elements connected to one another by means of a tube piece
  • Figure 4 is a perspective view of the tube piece in a separate view according to one embodiment.
  • FIG. 5 shows a perspective view from below of a piece of hose formed in one piece from an element
  • Fig. 6 shown in perspective two interconnected elements, with several hose inserts each and a cover device.
  • FIG. 1 schematically shows a weather protection device 11 consisting of a plurality of elements labeled 10, 110, 210, 310, each element consisting of a first tarpaulin 26 (see also FIG. 6) which is attached to horizontal and / or vertical struts 14, 16 of a scaffolding or other structure, not shown here, z. B. can be attached by means of straps 18, cords, hooks or the like.
  • This scaffolding stands for example in front of a work surface 22, for. B. the wall of a building, which is to be plastered or painted with paint.
  • Each element 10, 110, 210, 310 of the modular weather protection device comprises a first, inner tarpaulin 26 directed towards the scaffolding and a second outer tarpaulin 28 which is arranged at a distance therefrom and runs essentially parallel to the first tarpaulin, the inner and the outer Tarpaulins are connected to one another by lateral tarpaulins 30, 32, 34, 36 in such a way that a space 38 is obtained which is essentially airtightly enclosed by the tarpaulins, the space 38 being laterally connected to an air supply device 42 which generates an overpressure within the space.
  • a blower 44 can be used to generate the excess pressure, which may be arranged, for example, in the vicinity of the work station. Due to this overpressure against the outside air generated within the room, the elements 10, 110, 210, 310 acted upon in this way are stabilized in themselves and against one another by being inflated like a balloon.
  • a protective wall consisting of several elements is arranged in front of the scaffold.
  • the air layer enclosed in the elements Due to the air layer enclosed in the elements, it forms a heat insulation between a work surface on the one hand and the outside atmosphere on the other, so that not only rain and other precipitation are prevented , but especially cold temperatures cannot directly affect the work surface.
  • the bulkhead can perform another function, as in The prior art WO 98/13564 is also particularly emphasized, namely, it is possible to provide, in the inner, first tarpaulin 26 arranged, pointing towards the scaffold, closable or adjustable outlet openings, as indicated for example at 45, 47. Through these openings, air can escape from the interior of the room 38 in the direction of the scaffolding, for example to generate an air flow on the previously painted wall surface 22 in order to accelerate the drying process there.
  • the compressed air supplied may also have been previously heated by a special heating device, for example by an oil or gas heater or by an electric furnace, so that the air supplied to the room 28 exits the nozzles 45, 47 as warm air and thus an even stronger one Accelerates the drying process, alternatively or additionally, but also keeps cold outside temperatures from the work surface 22, in order to be able to continue working in the area of the protected work surface in winter, for example, despite outside temperatures below freezing.
  • a special heating device for example by an oil or gas heater or by an electric furnace
  • the further element 110 arranged next to the element 10 and the further element 210 arranged above the element 10 are each supplied with air from the element 10 by air supply devices 142, 242, which will now be described in more detail below. 3, one (right) side wall 32 of the element 10 can be seen in a cross-sectional view, as can the other (left) side wall 30 of the element 110.
  • a piece of tubing 48 is now preferably formed with a rectangular cross section, this piece of tubing 48 being formed from a material which has properties very similar to those of the material from which the elements 10, 110 are made, that is to say in particular is airtight and flexible.
  • the material of the elements 10, 110 fabric reinforced PVC represents, ie a film, such as is used for covering truck bodies, one will also use such a PVC fabric film for the tube piece 48.
  • This has the great advantage that the possibility of movement of the individual components is very similar, thereby facilitating movements that result when elements 10, 110 are inflated.
  • Such movements arise from the fact that, when there is no excess pressure, the wall surfaces of the element 10 hang limply while they are inflated like a balloon after inflation. This means that the middle areas of the inner and outer tarpaulins are pressed outwards due to their large area, see FIG.
  • arrows 35, 37 while the edge areas with their relatively small area are in turn pulled inward due to this movement outwards,
  • arrows 39, 41 which shows a sectional view of the side tarpaulins parallel to the rear (inner) wall 26.
  • the tube piece 48 should accordingly have such an axial extent A that movement of the side walls can be absorbed away from one another, and on the other hand also form folds 43 if the distance between the side wall regions 50, 150 becomes smaller.
  • the end of the tube piece 48 is designed such that an opening 52 in the adjacent side wall 32 or 30 of another element 110 can be connected essentially airtight to the side wall region or edge 50.
  • the end 54 shown on the left is arranged with the edge 50 of an opening 52 in the side wall 32 of the element 10 in a non-detachable manner, for example glued, see adhesive layer 56 in FIG. 3, or also secured by a seam.
  • connection can also be in one piece, at least in partial areas.
  • 5 shows a piece of hose 148 which has four walls 58, 60, 62, 64 and thus forms an elongated rectangle in cross section.
  • the two longer walls 58, 62 which lie opposite one another, were created when the rectangular opening 52 was formed in the element wall 32 by making a central longitudinal section 66 and a cross section 68 at each end and the two tabs 70 that then formed folded out and connected to two transverse walls 60, 64 arranged perpendicular thereto, for example in that tabs 72 extending from the side walls 60, 64 are glued to the wall regions of the tabs 70 in the position shown in FIG. 5.
  • the side walls 60, 64 in turn are glued to the tarpaulin 32 by means of tabs 74 in a similar manner as has already been described with reference to FIG. 3.
  • At least one end of the tube piece 48 or 148 must be releasably connected to the edge 150 of an opening 152 in the adjacent side wall 30 of the end element 110, according to FIG. 3 by means of push-button devices 75 the arrangement is such that an element 10 is provided on its one side wall (e.g. 30) an opening 52 with the male or female parts of snap fasteners 76, 78 on the outer edge surface thereof, while the closest (80, 82 for element 10 in Fig 1) and / or opposite wall 32 is equipped with complementary (female or male) push button parts.

  • a blower 44 is then possible both from the left and from the right (top or bottom) according to FIG. 1, the air supply adapter 42 shown in FIG. 1 representing an arrangement which allows the end of the hose 46 to pass into, for example, a hose Approach provided with compressed air, which can be connected to an opening arranged in the wall 30.
  • a hose Approach provided with compressed air
  • a second row of elements 210 is provided, which are arranged parallel to the first row and are each to be supplied by the element arranged below. Then elements with opposite connections are sufficient for this second row.
  • elements of the last row, 310 even elements with only one connection are sufficient if the air connection shown in the direction of the arrow is sufficient.
  • other routings can be useful, for example it could be advantageous to first supply the work surface that is most sensitive to frost than, for example, the top row with the elements 310. Then an air flow is sensible, as shown by the dashed arrows in FIG. 1 is indicated. In this case, several elements of the type are required in which two side walls lying next to one another are each provided with an air passage.
  • connection lines 86 between the side tarpaulins 32, 30, 34, 36 and the ones pointing at least to the outside are provided according to FIG. 3 to equip the second tarpaulin 28 of the element 10, 110, 210, 310 with a thickened cross section 88 which can be inserted into a correspondingly undercut groove 90 of a piping rod 92.
  • This thickening is expediently created by sewing a flexible strip 94 placed on the loop onto the edge area of the (preferably outer) tarpaulin 28, see seam 96, in which loop a stabilizing rod 98 is additionally inserted, such that the combination of Rod 98 and circumferential strip 94 fit exactly into the undercut groove 90 of the piping 92.
  • the associated edge of the neighboring element 110 is held in this piping rod 94.
  • the inner side of the elements facing the scaffolding is less exposed to wind and weather and can possibly do without keder poles (although too For stabilization purposes, it often makes sense here, too, to first pull in the corresponding keder rods at the lower end of the total area).
  • the individual elements 10, 110, 210, 310 each consume a certain amount of the supplied air, be it due to unavoidable leaks or be it because air is intentionally removed via valves in order to supply it to the work area behind the weather protection device.
  • This air consumption must be compensated for by the corresponding air supply devices 42, 142, so that a constant air flow flows through the air supply devices 42, 142.
  • it is important that the opening 52, 152 is not too small with respect to the area of the associated side wall 32, 30. For this reason, it is favorable if the tube piece 48, 148 has a rectangular cross-section with a longitudinal extension L and a cross-sectional extension Q that is only slightly smaller than the length L1 or width Q1 of the associated side wall 34 of the element 10.
