Abstract

A Device for targeted sealing of longitudinal gaps or Folding [6] vertically or horizontally between casement [5] [7] and window frames [4], preferably in buildings [1] can be applied, characterized in that they are made of a thin-walled Plastic tube [12], which with a preferably curing, elastic sealant [13] can be filled.

Description

1. Name of the invention

Device for sealing window wings and window frames in structures

2. Technical field to which the Invention relates

The device according to the invention 4 ] is too far apart [ 6 ] applicable in the construction sector. It is preferably suitable for older window sashes and balcony doors [ 2 ] of wood and its associated in the building [ 1 ] walled frame [ 4 ], if they are to be sealed only in one area against strong penetrating moisture from the outside, such as driving rain. The window gaps which become wider in the course of the operating time due to wear and aging, which in an improved form with seam [ 9 ] and groove [ 10 ], the outside moisture, especially in the case of backwater, flows inwards and thus leads both to the strain on the surrounding building structure and to the deterioration of interior hygiene (eg due to fungal infestation).

The moisture-proof area is largely located in the lower part of the window assembly [ 3 ], which is especially affected by wear; but even this - mostly small area - could be sealed with the device according to the invention.

3. Relevant prior art

Surface treated casement windows [ 1 / 2 ] are made of wood in older buildings assemblies that both light [ 8th ] let into the building as well as in closed rooms a fair air exchange and thus the stagnation, which occurs mostly by condensing humidity, counteract.

at Repair or repair work of older buildings it is one of the most important tasks, elaborated windows and doors, usually due to normal wear and tear are to seal; it is often the mistake, Install hermetically sealed windows, which is another building physics - mostly to be observed in new buildings - follows. Preferably in Old buildings leads to low air exchange near the windows by condensate to wet interior walls and below to fungal infestation and damage to the building fabric.

Also, the sealing of older windows in the longitudinal edges [ 6 ] between casement [ 5 ] and frame [ 4 ] - z. B. with subsequently mounted elastic sealing lips - often therefore not sufficiently effective, because the gap widths to the lower corners of the window 3 ], are subject to greater wear, so are more elaborate, and thus specifically backwater, which usually only acts for a short time, can not sufficiently deter.

4. Technical problem to be solved

strongly blocking abutting edges, preferably folds between window frames and casements, are to be sealed so that unimpeded rainwater penetration is prevented but continues ensures adequate ventilation of the interior becomes.

5. Presentation of the invention

A thin-walled hose, preferably made of plastic [ 4 ] which can protrude beyond the edge edge region which is to be sealed vertically in a suitable length and has a diameter which, when filled, allows a full insertion into the fold between wings [ 7 ] and frame [ 4 ] (in simpler or other constructions in the gap [ 6 ]), without its protruding too far beyond it, becomes with a self-hardening, as elastic as possible mass [ 13 ] - about silicone rubber - filled. After insertion into the groove [ 10 ] the wing [ 7 ] closed for curing [ 11 ]. Thereafter, the supernatant or swollen mass is separated cleanly. Tearing of the tube is not disadvantageous, since the sealant spreads better around the fold, especially if smaller depressions or roughness can absorb part of the sealant in it. In the window gap opening a double-sided bonding of the sealant with the outer parts [ 9 ; 10 ], a release agent can be applied on one side. However, if a two-sided bonding is desired brings two correspondingly thinner hoses and here preferably used as a release agent, a plastic film, which is removed after curing - such as when the work area is cleaned of the supernatant mass.

6. Advantageous effect of the invention

If the abutting edges [ 6 in 2 ] or fold [ 9 . 10 in 3 ] of the window sash frame construction are worn out so far during the period of use by dry processes of the wood and by abrasion that penetrating rainwater or excessive air passage necessitate a repair, the device according to the invention is 4 ] to use. The sealing against rainwater then takes place up to the level of the inserted device [ 3 ]. By folding her lower part at the corner, her water-inhibiting effect is superimposed with that of the water leg. The separate insertion of the inventive device in the horizontal part is only necessary if the water leg is ineffective or if the air exchange is too high and the effectiveness of Nutzraum-heating power decreases too much.

• – Das Eindringe von Feuchte, insbesondere von Schlagregen, wird weitestgehend verhindert.
• – Der verringerte Fensterspaltluftaustausch ist vernachlässigbar.
• – Bei normalem Winddruck erfolgt kaum ein erhöhter Feuchtigkeitstransport in den Innenraum.
• – Das Verfahren eignet sich auch zum Abdichten von zu weiten Falzen oder Spalten gegen Zugluft.
• – Bei Reparaturarbeiten ist die Montage vereinfacht und der Arbeitsplatzbedarf gering.
• – Die Reparatur kann erfolgen, ohne den Rahmen [4] aus dem Baukörper zu entnehmen.
• – Das dosierte Befüllen des Schlauches [12] der erfinderischen Vorrichtung erlaubt eine vereinfachte Korrektur bei Nacharbeiten.
• – Die Kosten und mögliche Zusatzkosten durch hermetische Fenster entfallen.
• – Da die Bauarchitektur erhalten bleibt, entfallen Stadtarchitektonische Verwaltungsarbeiten.

In summary, the advantages of the device according to the invention are the following:

• - The penetration of moisture, especially driving rain, is largely prevented.
• - The reduced window gap air exchange is negligible.
• - At normal wind pressure there is hardly any increased moisture transport into the interior.
• - The method is also suitable for sealing too far folds or gaps against drafts.
• - For repair work, the assembly is simplified and the workplace requirements low.
• - The repair can be done without removing the frame [ 4 ] from the building.
• - The metered filling of the hose [ 12 ] of the inventive device allows a simplified correction during reworking.
• - The costs and possible additional costs due to hermetic windows are eliminated.
• - As the architecture of the building is preserved, urban architectural management work is eliminated.

7. Description of a way to execute the invention

[ 3 ] shows the structure of a window frame construction for the device according to the invention [ 4 ] can be used. Is z. For example, to seal the lower corner area 3 ], the device according to the invention 4 ] like a cylinder on the lower corner. then put it in the groove [ 10 ] and the window sash [ 7 ] with the fold [ 9 ] locked [ 11 ]. The material [ 13 ] now fills the worn space while the excess mass swells out. By waiting for the curing time, the device retains [ 4 ] add the desired new form; she remains in the wear room.

The effluent on the window sash liquid that can not be dissipated through the water leg and would flow in the especially towards the corners widened gap is denied in this way the penetration into the interior. This type of application also largely withstands increased wind pressure, which is particularly noticeable in driving rain. The yielding of the sash then depends only on the game in the fittings -. The hinges [ 15 ] - from.

An improved bonding with the folding or cleavage surface is achieved by the inventive device [ 4 ], which is designed as a roll, is specifically weakened by perforations at the contact surface [ 14 ], so that when closing [ 11 ] of the sash, depending on the pressure conditions, the sealant [ 13 ] lets through or bursts. Roughening or inserting small holes in the outer frame [ 4 ] still enhances the adhesive effect.

8. Content / Summary

Using the example of a leaky window sash it is shown how, with the help of a thin-walled plastic hose and self-hardening elastic material, it is only possible to carry out a complete sealing repair in the necessary area so that one avoids the change of window frames. The former condition is restored without loss of substance. 9. citations DE 41 35 360 A1 DE 100 49 299 A1 DE 43 10 754 A1 DE 102 12 231 A1 DE 44 27 045 C1 DE 26 47 742
