Door leaf made of sheet steel!

The innovation concerns a sheet steel door leaf for use with a steel frame in building construction.

Door leaves are available in a wide variety of designs and forms as general to S-fcaßd. belonging to technology known * In connection with a frame corresponding to the door leaf, the same can be found as an apartment * -, Room and closing doors in building construction in general turn.

The door leaves that can be described as conventional are made of wood * Likewise, the associated frame is made of wood. It can this is a solid material Form hollow body, each having an end plate on the two sides of a frame structure in is applied in a manner known per se by gluing or the like »In the course of industrialization in general, one has moved on to manufacture the door leaf and frame from a material that can be quickly and easily can be processed and has a long service life »

As a result, door leaves have become known that contain metal as their basic material. «It's similar here like a wooden door leaf designed as a hollow body, because even with the door leaf made of metal, panels are attached on both sides to a support frame or the like *. In the known, made of metal doors has a disadvantage that the connecting seams between Plate and support frame are visible and require post-treatment »But even after such a treatment Post-treatment the character of a wooden door is not given »

Door leaves are also known for S ^ ahlzargen that have a support frame made of metal and both ~ have plastic end plates on each side »

The inventor has now set himself the task, in the aforementioned area of door leaves, another Embodiment to reveal which: the expectations that are made of a made of wood Frame and leaf are placed on the existing door. The task set will be according to the novelty solved in that the door leaf from a box and a lid, which is firmly connected by gluing, welding, riveting or the like, the box on the long sides and the top side a U-shaped, circumferential, inwardly directed bend and the lid has a bent portion corresponding to the angled shape of the box »

Another feature of the innovation can be seen in the fact that the bend of the cover is constructive is designed so that it engages behind the U-shaped bend of the box. But it also exists the possibility that the bend in the lid lay flat on the bend of the box "

"Ij.

Between the box and the lid there is an insert that serves as thermal insulation and soundproofing made of foam or a similar Material arranged, which is "firmly connected" to the box and / or lid with a high-quality adhesive or the like

The innovation, consisting of a box and a lid The door leaf is made of thin-walled sheet steel and is galvanized, phosphated and chromated Coating on. There is also the option of covering the door leaf with a plastic cover or the like. Material to be provided.

Finally, it should also be mentioned that the box and the lid are fixed on their lower side introduced angle plate or the like »experience a connection»

The following description is provided for explanation of the object according to the innovation, of which an exemplary embodiment shown in the drawing, ea show:

Fig * I is a perspective view; 2 shows a section along line II-II in FIGS Fig. 3 is a section along line III-III in Fig.

As can be seen in Figures 1 to 3, the door leaf is denoted by 1 * on the known per se the frame belonging to the door leaf, which is not shown in the drawings, will not be discussed in more detail are »The door leaf 1 according to the innovation consists of the box 2 and the cover 3» The Ver—

Glue binding of parts 2 and 3 takes place by / welding, riveting or the like. After the connection, the two parts 2 and 3 form a stable., Torsion-resistant. Door leaf 1, which corresponds to a wooden door in terms of shape and in particular in terms of the angled cover. D _u rch the angling 2 ^f it will be apparent that even the edges of the door leaf 1 from the same, the door surfaces forming material are deformed *

In the door leaf 1 according to the innovation, the connection of box 2 and cover can be made so that once the bend 3 'reach behind the bent angles 2 ¹ and, on the other hand, that the same 3', seen from the front, is supported on the bent portion 2 ^{f of} the box 2 »

In the free space between the box 2 and. the lid 3 is a thermal insulation and soundproofing serving insert 4 introduced, which is made of a plastic

m, 6 ■ »

with a microporous structure or the like "consists" The connection of the insert k to the box 2 and / or cover 3 is made via an adhesive layer 5 or similar connecting means "The inserted insert k gives the door leaf 1 an absolute stiffening. The insert 4 removes the metallic body sound that adheres to the material of the door leaf i "

The box is connected at the lower end 2 and cover 3 over an inserted angled plate 6 that extends over the entire width of the door leaf » The fastening of the angle plate 6 is also carried out by gluing, welding, riveting or the like. " The door leaf 1, which is made from a thin-walled steel sheet, according to the innovation, has a galvanized, pho & phated and chromated coating. Instead of this coating, however, a coating made of plastic or the like can also be used. to step"

The advantage of the subject of the innovation over the known is to be seen in the fact that the material properties In conjunction with the zinc coating, a door leaf with a long service life was created is. Depending on the requirements, this can be a door leaf which is far below the cost of the known door leaves

with a decorative, cozy, warm coat of paint will.
