NL8603192A - INSULATING CLOSURE FOR BUILDINGS. - Google Patents

Abstract

A seal or partition for refrigerators can be reeled up and is a flexible canvas with flexible foamed resin, coated on both sides with smooth plastic material or synthetic rubber; the complete material can be moved up and down vertically and its edges are guided along tracks with grooves; it is held by belts which are fixed to one end and run over one or more winding rollers. The flexible prod. can be unwound upwards or downwards. The foam used is closed-cell polyether, polyurethane or polystyrene and its coating is PVC, neoprene or "Hypalon" (R.T.N.).

Insulating barrier for buildings.

The present invention relates to an insulating barrier for buildings, such as warehouses, auction halls, cold stores, warehouses, warehouses and warehouses.

The goods are increasingly being transported in and out of such spaces with trucks, trailers, containers, on pallets, racks, etc.

Therefore, wide and high portals are required for this.

Where many goods, such as food, meat, vegetables, fruit, but also chemical electronic equipment, etc., have to be stored at a certain temperature constant, the enclosure of the spaces presents problems.

On the one hand, the space for large vehicles and transport packaging must be easily and quickly accessible, while on the other hand effective insulation against too high and too low temperatures, solar radiation, moisture, snow and drafts is urgently required.

In many cases, good insulation for noise control and sealing to protect against theft and vandalism is also desirable.

The known and conventional closings known from the prior art, such as gull-wing doors, horizontally-vertically folding doors with mechanical balancing devices, with or without electromotor actuation, and the slatted roller shutters cannot sufficiently meet all these requirements. meet.

In order to provide a satisfactory solution to this technical problem, a new type of barrier has been developed, which through its construction represents a solution for entrances and exits of the buildings as mentioned in the preamble.

The gantry insulating barrier of the present invention is characterized by a retractable and flexible door body, which consists of a 8603192 -2-t filling of flexible foamed plastic (polyether, polyurethane or polystyrene, with closed cells), which is applied on both surfaces is lined with smooth webs of flexible plastic or synthetic rubber, which door body can slide vertically up and down, guiding along the edge in guide profiles with stop members, and held by webs attached at one end, which run over one or more winding rollers , and in their extension the flexible door body also coils upwards.

The winding rollers are mounted on horizontal shafts on the inside of the lintel at the top and are axially driven by an electric motor, thereby pulling the door body on the girth, which is weighted at the bottom, by a rod.

The door body wraps around the winding rollers.

In an alternative embodiment, the webbing pulls the door body upwards around the weighting spindle, so that the door body remains coiled around this spindle 15 under the take-up roller.

Due to a small pressure difference between the interior and the environment, which arises in cooled spaces, the door body is pressed against the stop part of the guide profile on its sides, so that a perfect closure is maintained in the lowered position.

The door body is formed in wide webs, which are shallow notches at regular intervals so that the flexible insulating material can be smoothly rolled up and down.

A lock can be provided on the side, and the bottom of the spindle can be finished such that a gap for aeration can be formed between the floor and the bottom of the rollable material of the door body; it is also possible to mount a closing device at the bottom.

The electric motors can be mounted above a fence against a supporting beam and are operated with switches on the inside and / or outside.

30 External switches can be locked.

The power supply for the motors is 380 V three-phase current.

It is possible to provide fall protection for the entire interior.

The thickness of the insulation of the door body is preferably 20 mm, but other thicknesses are also possible, provided that the material remains sufficiently flexible for rolling up and down.

The invention is further elucidated with reference to the annexed drawings 1 to 7, which schematically show different embodiments of the construction according to the invention.

These serve as examples, to which, however, the inventive idea is not limited.

The position neurons show corresponding parts in all figures.

no.

Figure 1 shows a view of a closure of a portal or doorway, in which the door body (1) is lowered with guide edges in guide profiles (4).

10 Figures 2, 3 and 4 schematically show horizontal cross-sections of the guide profiles (4) against the post of the portal on the inside and on the outside of the opening to be closed, with the stop part and the edge of the door body, consisting of made of foam plastic filling (2) and surface coating (3).

Fig. 5 schematically shows a vertical section through a portal side, in which the flexible door body (1) hangs between a guide (5) between the guide profiles (4) and over a wind-up bar (6), which passes through an axis (8) of a electric motor (9), mounted at the lintel (7), can be driven in both directions of rotation, so that the door body is rolled up around the gantry (6) in open position above the portal.

At the bottom is the rod (10) for weighting and closing.

Figure 6 is an embodiment of the same principle, in which the wind-up ridge (6) driven by the motor (9) via the shaft (8) is mounted above the lintel and the door body (1) by a longitudinal girth (5). can be pulled up.

Figure 7 shows another embodiment of the invention in vertical section, the door body (1) being lifted over the spindle (11) at the bottom by the girth (5) and rolled around this spindle (11), so that it hangs under the winding pulley (6).
