Roller shutter box

The invention aims to create a simple and cost-effective roller shutter box in a stable design, with good thermal insulation and easy installation.

This object is achieved according to the invention by the characterizing features of claim 1.

The subsequent subclaims contain design features which represent advantageous and beneficial further developments in the solution of the task.

The roller shutter box according to the invention is advantageously formed from a profiled, galvanized steel casing, vapor-barrier thermal insulation panels arranged therein, plaster bonding plates attached to the outside and box-shaped, bent end walls, each of which accommodates a vapor-barrier thermal insulation panel.

The steel casing has two downward-facing, three-fold bevelled longitudinal walls on its flat horizontal lintel wall, each with a different height but an identical, mirror-image bevelled profile. The steel casing in a self-supporting design gives the roller shutter box a stable and robust design. The thermal insulation panels arranged inside the steel casing under the lintel wall and the longitudinal wall on the left and right, as well as the thermal insulation panels installed in the box-shaped end walls, are made of rigid polyurethane foam with aluminum lamination on both sides and give the roller shutter box

optimal thermal insulation, which is equal to the existing double-shell masonry.

This roller shutter box is easy to install and can be connected to the masonry and a room-side cover using the plaster bonding agent plates and enables easy fastening of the cover from below using the wooden strip inserted into the underside of the internal thermal insulation panels.

The drawings show an embodiment of the invention, which is explained in more detail below. It shows:

Fig. 1 a perspective of a roller shutter box seen from the outside of the house,

Fig. 2 is a perspective view of a longitudinal end region of the roller shutter box with the front wall assumed by the longitudinal casing.

The roller shutter box has a self-supporting galvanized steel casing (1) with a lintel wall (2) and two multi-folded longitudinal walls (3, 4).

A vapor-barrier thermal insulation panel (5, 6) is arranged inside under the lintel wall (2) and inside on the longitudinal wall (3) on the side of the steel casing (1), each of which extends over the entire wall surface.

A plaster bonding agent plate (7, 8) covering the entire wall surface is attached to the outside of the lintel wall (2) and to the outside of the room-side longitudinal wall (3) of the steel casing (1). A beveled end wall (9) made of galvanized steel is inserted into each of the two front ends of the steel casing {1) with a vapor-tight thermal insulation plate (10) inserted into the end wall box (9a) and facing the masonry. The thermal insulation plates (5, 6) located in the steel casing (1) are set back at the front ends by the box thickness of the end walls (9).

The lintel wall (2) of the steel casing (1) is flat and lies horizontally; the two longitudinal walls (3, 4) bent downwards at the long edges of the lintel wall (2) have different heights and an identical, mirror-image

arranged L-shaped folded profile consisting of a long wall leg (3a, 4a) pointing vertically downwards, a short horizontal web (3b, 4b) pointing outwards and a short edge web (3c, 4c) pointing upwards.

The thermal insulation panels {5, 6, 10) consist of a rigid polyurethane foam with aluminum lamination on both sides (11) as a vapor barrier.

A wooden strip (12) is embedded in the bottom of the room-side thermal insulation panel (6) for attaching a bottom cover for the roller shutter box.

The thermal insulation panels (10) are inserted flush with the outside into the box-shaped end walls (9) which are open to the outside.

Rivet nuts (13) for mounting the roller shutter mechanism are inserted into the end walls (9).

The longitudinal wall (3, 6, 8) on the room side has a belt outlet (14) with an inclined plastic belt guide in a longitudinal end area above the rivet nuts (13).
