Description

Technical environment

The The invention relates to a smoke extraction device and / or dome light or flap, acting as one on a thermally decoupled frame hinged flap, skylight or light flap is formed, and the rectangular frame is arranged on a flat roof Aufsetzkranz rests.

State of the art

Out The prior art are sufficient versions of Skylights, flaps or the like known on flat roofs, For example, industrial halls are arranged. It can These skylights or flaps also as smoke extractors or ventilation devices are used, these then be controlled by a cylinder or electric motor and in case of fire / ventilation condition, swing the dome upwards, so that smoke or the exhaust air can be removed.

These known flaps or light domes are constructed such that a hinged rectangular frame rests on a arranged on the flat roof Aufsetzkranz in the closed state. The skylight dome or flap is attached to the rectangle frame. In these light domes known from the prior art is according to the DE 200 21 139 a thermally decoupled frame known, wherein the frame is composed of conductive and non-conductive profile struts to a rectangular profile. The profiled frame consists of an inner profile and an outer profile, wherein the inner profile and the outer profile are connected by means of the top surface and the bottom surface forming plastic moldings, so that forms a thermally decoupled frame in the form of a box section.

When disadvantageous in this known from the prior art thermally decoupled frame, it is considered that the production of a Such a frame is expensive, and it is particularly in the field the chafing comes to discontinuities, the isolation effect unfavorably influence. He is also because of its elaborate Art cost-inconvenient.

task

Of the Invention thus raises the problem of a thermally decoupled Frame for a smoke extraction device and / or dome light or to further develop the valve which, on the one hand, overcomes the disadvantages, on the other hand, the rectangular frame by its construction is much cheaper to produce, and the improved thermal Has isolation.

solution

According to the invention this problem is solved by the main claim; further education emerge from the dependent claims.

at the inventive solution of thermal this decoupled rectangular frame consists on the one hand of a box-shaped plastic hollow profile and on the other hand U-shaped aluminum profiles, each separated forming a gap between the legs of the aluminum profiles are set on the sides of the plastic profile. Such Construction has a special thermal effect on, in particular, the U-value is significantly improved. Because of this construction can in a simple way first a plastic frame can be created, which provides a so-called basic strength. Then each of the inside as well as the outside forth the corresponding U-shaped aluminum profile easy and easy to set. This results in a stable, thermal separate rectangular frame profile, which is easy to install and also much easier to handle from the manufacturing cost is. Because the necessary for the production of the frame Profiles can be kept as a piece of string.

Around To give the frame the necessary strength, are the U-shaped aluminum profiles each with their bottom area fixed on the end walls of the plastic hollow profile. Here are the inside of the side walls of the hollow plastic profile Metal inserts in the form of sheet steel strips provided as Abutment for the fixed with screws U-shaped Aluminum profiles are provided.

there in particular, the individual legs of the U-shaped Aluminum profiles corresponding projections, wherein on the legs, the resting on the bottom surface, grooves for receiving seals are formed, which in turn contact the Aufsetzkranz. On the thighs, which rest against the top surface are Lugs molded to define the skylight dome, the flap or the like are determined.

Description of the drawings

One Embodiment of the invention is in the single figure and will be described in more detail below.

embodiments

The figure shows in the sectional view of the sub-area of a smoke extraction device and / or dome light 1 acting as one on a thermally decoupled frame 2 hinged flap is formed. The frame 2 lies here as a rectangular frame on a arranged on a flat roof Aufsetzkranz 3 on. Here is the rectangular frame 2 on the one hand from a box-shaped plastic hollow profile 4 formed, wherein the rectangular frame 2 on the other hand from U-shaped aluminum profiles 5 and 6 is formed. In each case, are separated from each other, forming a gap 7 , the U-shaped aluminum hollow sections 5 and 6 on the outside and inside of the plastic hollow profile 4 set, so that between the thighs 5.1 . 5.2 and 6.1 . 6.2 the aluminum hollow profiles 5 and 6 a gap 7 above and below the plastic hollow profile 4 forms.

The aluminum profiles 5 and 6 thus partially grasp the plastic hollow profile from the outside and from the inside 4 a, so that the thermal bridge results through the inner plastic hollow profile.

On the thermally separated rectangular frame 4 a non-illustrated cylinder or electric drive can be arranged with the Aufsetzkranz 3 is connected, wherein the cylinder for pivoting the dome light 1 with the rectangular frame 2 communicates. As can be seen from the figure, the U-shaped aluminum profiles 5 and 6 each with their bottom area 5.3 and 6.3 on the side walls 9 and 10 the plastic hollow profile 4 set, which are formed inside ribbed. As can be clearly seen, are each on the inside of the side walls 9 and 10 the plastic hollow profile 4 Metal inserts in the form of sheet steel strips 11 arranged, which are held by the ribbing in position. The sheet steel strips 11 serve as an abutment for the screws 12 , in particular the U-shaped aluminum profiles 5 and 6 from the bottom side 5.3 and 6.3 fro firmly with the plastic hollow profile 4 connect.

To a positive connection of the interlocking profiles 4 . 5 , and 6 produce, lie the U-shaped aluminum profiles 5 and 6 with her thighs 5.1 . 5.2 and 6.1 . 6.2 on the top surface 13 and the floor area 14 the plastic hollow profile 4 at. As can be seen from the figure, are on the thighs 5.2 and 6.2 at the bottom 14 abut, grooves 15 for receiving seals 16 formed. In the resting state of the rectangular frame 2 on the cradle 3 lie these seals 16 on the upper edge area of the Aufsetzkranzes 3 on, so that in this area, a thermal decoupling is given.

On the thighs 5.1 and 6.1 at the top 13 concerns are approaches 17 molded to the fixing of the dome light 1 are determined.
