Device for protection against precipitation (rain or snow) and

from sunlight

State of the art Hat, umbrella, tent constructions, compressed air halls, massive Roof structures

problem

All of the above-mentioned structures (with the exception of compressed air halls) above a certain size require both solid foundations (foundations) and supports (expensive ceiling structures depending on the span) and are very complex to assemble and disassemble. The disadvantage of compressed air halls is the access restriction due to the pressure locks.

invention

A construction of impact bodies, which are hollow cubes ( Fig. 1 A ) made of plastic that is permeable to light and ultraviolet radiation, filled with gases, some of which are lighter than air,

which are added together, secured by orthogonally tensioned steel cables ( Fig. 1B), which are attached to the cubes at the four lower corners using commercially available snap hooks. Shape stability over greater distances is achieved by a compartment-like bracing made of compression rods ( Fig. 1 C ), four to five times as long as the cubes, made of carbon fibre reinforced plastic (takes on vertical pressure) and their connection with tension cables ( Fig. 1 D ) made of stainless steel (takes on horizontal tension), with the impact bodies taking on horizontal pressure. The cubes are provided with an inlet valve ( Fig. 1 G ) and an overpressure outlet valve on the underside. The cubes are connected to each other and to a supply unit at the holding points via connecting lines ( Fig. 1 F ). This means that the total weight of the structure (buoyancy or downforce due to load changes, e.g. snow) can be controlled and any diffusion losses of the gas can be compensated for. This means that only the wind load has to be transferred horizontally and vertically. A two-layer film (Fig. 1 E) is laid over the impact bodies (plastic cubes) in glued strips. This film is flanged to the pressure struts and FA. KUNClC

This foil is secured against lifting. This foil is connected to a compressed air generator at the holding points. This makes it possible to heat the surface of the device by blowing in preheated air. If the blown-in air is mixed with colored gas, the transparency can also be controlled in whole or in part. The impact bodies can be easily and without any problem replaced individually. The overhang of the pressure rods ensures easy access to the entire underside of the device for maintenance purposes and when the device is sitting on the ground.

Beneficial effect

With the construction described above, wide-span devices (Fig. 3,4,5) for weather protection can be erected more quickly, as the device can be manufactured and assembled largely in the factory. Only the anchor points still have to be erected or anchored on site. The device can then be transported from the assembly site to the application site using towing airships. Likewise, a change of location can be carried out quickly and easily for temporary use. The dismantling and reassembly costs can be reduced to a minimum (installation of anchor points).

Commercial use

In the Federal Republic of Germany alone, hundreds of millions of euros in damage are caused every year because a wide-span, column-free roof over temporary work sites is not possible at low cost. The above device makes it possible for the first time to protect construction sites at low cost (Fig. 3,4). Furthermore, this construction is ideally suited to protecting listed buildings (excavations, stadiums (Fig. 5) and other large-scale buildings) and their visitors from the effects of the weather without the need for columns (reduction to at least three stopping points).

Claims (1)

Device for protection against precipitation (rain or snow) and solar radiation, characterized in that A) Cube-shaped hollow bodies (A) made of plastic transparent to visible light and ultraviolet radiation and B) Stainless steel retaining ropes (B) and C) Compression struts (C) made of carbon fibre reinforced plastic with four times the length of the hollow bodies (A) and D) Tension cables made of stainless steel (D) and E) Two-layer sealing films enclosing cavities made of plastic permeable to visible light and ultraviolet radiation and F) Connecting cables made of transparent plastic and G) Inlet and outlet valves and H) Pressure struts made of carbon fiber reinforced plastic with four times the length of the hollow bodies (A) in a special design for edge stiffening are joined together in such a way that the hollow bodies are put together in a square in one plane and are fixed with holding cables at the top and bottom. For better dimensional stability, pressure struts are hung at the corners of these hollow body groups and assembled with tension cables to form dimensionally stable modules, with the impact bodies taking on horizontal pressure, the pressure struts vertical pressure and the holding and tension cables horizontal and vertical tension. These modules can be freely added together. In edge modules, the pressure struts are designed to be particularly rigid. A two-layer hollow film is placed in parts over the hollow bodies, glued together and flanged to the pressure struts. The hollow bodies are provided with controllable valves and connected to each other with connecting lines. These lines are connected to filling stations at several collection points.
and filled with technical gases under pressure, allowing the total weight, surface temperature, transparency and fire behaviour to be dynamically adapted to changing requirements as required.
