DE2909562A1 - Front lining for roller blind lintel - comprises special plate, and heat sealing is provided by series of polystyrene wedges - Google Patents

Abstract

The roller blind lintel can be used for all windows and doors capable of taking a blind. Right around it, on the outside and the inside, a 5cm thick complete heat protection is incorporated. Static protection is built-in with it, and the front lintel lining is concreted in. This lining comprises 5 cm 'Heratekta' (RTM) plate. The structure is normally 220 mm high, and comprises 50 mm concrete and 50 mm polystyrene joined by plastic nails. To achieve good heat sealing, a series of polystyrene wedges are inserted.

Description

Prefabricated roller shutter lintel (according to the attached drawing)

Description and explanation The entire lintel with cover is called Prefabricated part manufactured, with both parts, because of the weight, laid separately will.

The prefabricated panel (No. 1 of the drawing), which in height and Thickness can be manufactured as required, the height of 220 mm in the normal case is sufficient, consists of 50 mm concrete B 25 and 50 mm styrofoam, which is secured by means of plastic nails (No. 6) are connected to each other. A styrofoam wedge is used for even better thermal insulation (No. 10 and 11) glued to the cover. The aperture still has the advantage that the Sound insulation is much better than the conventional type, whereby the window, or outer door, close to the lintel and using a flat iron (No. 2) on the lower one Part of the panel, which consists of 20 mm concrete, can be attached. The aperture is reinforced so that it can also be used as a load-bearing lintel.

The lintel, which is also prefabricated and fully insulated, receives the front Herathekta plate with 10 mm Heraklith and 40 mm Styrofoam (No. 3), or 30 mm Styrofoam and another 10 mm Heraklith on the inside (the latter only required if higher than 200 mm).

This plate also serves as formwork for the required lintel, depending on the statics.

On the horizontal thermal insulation of the lintel is a 50 mm thick Concrete ceiling (Er. 4) applied, which in this concrete the lower reinforcement (No. 12) of the lintel is installed according to statics. The reinforcement comes complete with all Bracket and assembly iron built in. The surface of the concrete becomes better Adhesion of in-situ concrete, roughened; Insulation and concrete are connected to each other with plastic nails The inner upstand (No. 5), which is 50 mm wide, is connected to the lower edge The ceiling is concreted and is also part of the static lintel.

The front insulation and the inner upstand (No. 14) made as high as the statics require.

In the case of the above-mentioned lintel, the core is poured with in-situ concrete. the front parking can also be made of concrete. No formwork is required, In the case of prefabricated ceilings, even the edge yoke is completely saved.

Only in the case of spans over 1.50 m is the prefabricated part with a Support supported.

In the event of a fall, the front storage with Herathekta plates is higher than 200 mm, for better posture during concreting, in the upper Area of the plate a plastic nail is pushed through the plate and held in place by wire attached to the bracket installed opposite.

This should be done every 500 mm and takes little time.

If the cover and the lintel have to be laid separately, so the joint between the two parts is made with simple, rigid cement slurry, The lower insulation of the lintel, as well as the rear of the cover, is in the direction of tension (Longitudinal direction) 30 mm placed on the masonry. The rest until the end of the support is fully concreted. The support length determines the statics.

An angle iron is attached to the front corner of the lintel or to the insulation 20/20 (No. 7) and is attached to the angle by means of an anchor, ~ 10, (No. 8) is welded, fixed in the concrete (only. 4). At this angle, the roller shutter manufacturer the lower bracket (No. 9), which is the plaster base, is fastened with flat iron.

The front panel, between the two angles (Er. 7 and 9), consists made of plaster on expanded metal (No. 13), the same can also be done with an impregnated plasterboard or with a visible glass plate (Eternit or Toschi). This panel can be highlighted architecturally.

The entire prefabricated part, lintel and cover, can be up to one span of 5.00 m.

if the structural engineer calculates several falls, as continuous beams, so the upper reinforcement is installed at the construction site and the lower one additionally on the prefabricated 50 mm concrete, the necessary additional reinforcement hung up.

The entire lintel with cover can also be made for walls with a thickness of 24 cm , of course, also for thick walls.

In the case of walls of 24 mm, the insulation on the panel is 30 mm thick.

A roller shutter profile must be used for a wall thickness of 30 cm with 50 mm insulation of 11 mm or mini profile can be used. Of course, aluminum profiles can also be used to be built in. If mini-profile is used with 30 cm thick walls, see above the insulation can even be increased to 70 mm.

The weight of the cover is approx. 29.5 kg per running meter, that of the lintel approx. 36.5 kg.

Both parts can thus be placed by hand.

When laying the height up to U.K. Aperture prepared, aperture laid in place and walled in, and at the same time the support for the lintel was created, which is placed on the panel or masonry.

With this prefabricated part, cover and lintel, a very good thermal insulation is achieved achieved and thus an energy saving.

As far as sound insulation is concerned, the prefabricated part is significantly better, than the usual roller shutter box.

The sound insulation is almost when using the aforementioned prefabricated part as good as with openings that have no shutters and therefore recommended for the legally stipulated noise protection zones.

The time saved compared to a conventional box is considerable, since the laying of the prefabricated part hardly takes more time than relocating a box.

The final price with the front plastered apron (No. 13) is hardly higher than the conventional type, which must be repeated again that the thermal insulation is significantly larger.

Another important point is that the reinforcement in the finished lintel is already built in, which is a cost saving.

The steel can be installed cheaper in the finished part at the production site than on the construction site.

For the manufacture at the production site, for the named finished part, the statics and the work plan, or a list (provided by the manufacturer as a blank is published), the wall thickness, opening width, static Includes lintel height and steel inserts.

B 25, K2, or any other quality is used for concrete quality.
