Description

The present invention relates to a sealing device for sealing a window frame in the lower region of a wall opening.

In European timber or solid construction, windows and doors must be properly sealed to prevent thermal bridges and the penetration of moisture. Sealing the lower corner areas of window frames in wall openings has been of particular concern to industry for years. It is often found that moisture enters the insulation material, so that the insulation effect is increasingly lost and serious damage occurs. Own studies are devoted to this topic and propagate an additional, i.e. second sealing level.

The problem is caused by pushing water into the corner where the window frame and the windowsill meet. The contemporary plastic windows have grooves on the outside into which this moisture occasionally penetrates. It has so far been an unsolved problem to adequately seal these grooves. This applies in particular to the groove on the underside of the window frame, which is usually sprayed with silicone.

Various manufacturers are currently working on solving the above problem. So far, the lower corner areas of window frames in wall openings have been sealed as well as possible with a high expenditure of time (approx. Half an hour per window) and considerable use of materials. In practice, however, it has been found that the sealing success is not sufficiently reliable and depends on the daily form of the contractor.

The present invention is therefore based on the object of permanently and permanently solving the problem of sealing a window frame in the lower corner region of a wall opening with predictable sealing results.

To achieve this object, the invention provides the sealing device for sealing a window frame in the lower region of a wall opening according to claim 1, wherein the sealing device has first, second and third sealing surfaces which are formed around an underside, an outside and a longitudinal edge side of the window frame below Intermediate to seal at least one seal.

The sealing device according to the invention preferably forms a shaped body which is composed essentially of a base body made of insulating material and a thin-walled plate material of greater hardness. It is preferably a completely finished component which, as such, is placed on the crossbar without additional foils or bitumen sheets are to be applied. The molded body has a suitable format to enable the window frame to be installed quickly in the wall opening. The molded body is preferably itself water-resistant in order to seal the problematic corner where the window frame and the window sill meet with a predictable sealing result permanently and permanently. In addition, it is ensured that the insulating effect of the molded body is retained, since penetration and penetration of the insulating material with water is categorically prevented by the sophisticated water supply of the sealing device according to the invention.

The present invention relates in particular to a sealing device for sealing a window frame in the lower corner region of a wall opening, which as a shaped body as shown in the 1 to 12 and 26 (alone) or as shown in the 13 to 25 (Installed state) is formed. However, the present invention also relates to a sealing device for sealing a window frame in the entire lower region of a wall opening, the sealing device having two (preferably symmetrical) corner parts as shown in FIGS 1 to 12 and 26 (alone) or as shown in the 13 to 25 (Installed condition). The corner parts are preferably connected directly or via an intermediate connecting element, preferably in one piece or monolithically.

The terms outside, bottom, longitudinal edge or side refer to the window frame as a reference point. For better orientation, the directions in relation to the window frame are indicated by arrows as a reference point in the figure representations.

Detailed description of the preferred embodiments

The advantageous embodiment of the invention is described below with reference to the accompanying drawings:
The sealing device 100 according to the preferred exemplary embodiment of the invention comprises three sealing surfaces 111, 121, 131 which meet at a common corner point 101. In the installed state of the sealing device 100 ( 13 to 25 ), in each case with the interposition of a seal 410, 420, 430, the first sealing surface 111 of the underside 210, the second sealing surface 121 of the outside 220 and the third sealing surface 131 of the longitudinal edge side 230 of the window frame 200 form a seal.

The sealing device 100 according to the invention essentially forms a cuboid shaped body of approximately 30 cm in length (from the front face 145 of the bench support section 140 to the front face 151 of the step section 150) and approximately 20 cm in width (from the side end face 152 to the side connection face 153 of the step section 150 ) and about 20 cm in height (from the lower edge of the end face 145 of the bench support section 140 to the upper side 125 of the first side section 120).

The support section 110 has the function of transferring the load of the built-in window onto the crossbar below. For this purpose, the support section 110 is essentially cuboid formed and has a length of approximately 19 cm (corresponds to the length of the sealing surface 111 from the side connection surface 114 to the sealing surface 131 of the second side section 130), a width of approximately 7 cm (corresponds to the distance between the end faces 112 and 113) and one Height of about 7 cm. In the area of the first side section 120, the first sealing surface 111 is slightly extended outwards over the end face 112 of the support section 110 in order to allow the window frame 200 to protrude beyond the window sill 300. In the plan view, the sealing surface 111 essentially has an L shape, the lower leg of the L shape facing the second sealing surface 121 and the third sealing surface 131 adjoining the lower leg of the L shape downward. The outside face 112 has a height of approximately 3.5 cm (from the support surface 141 to the first sealing surface 111), while the inside face 113 is approximately 2 cm high (from the top of the step section 150 to the first sealing surface 111 ). The first side section 120 adjoins the support section 110 as an extension of the lower leg of the L-shaped first sealing surface 111. The width of the first side section 120 is approximately 3 cm (corresponds to the distance between the side surface 123 and the side end surface 124), the height is approximately 15 cm (distance between the underside and the top side 125) and the length is approximately 9 cm (corresponds to the distance the second sealing surface 121 and the outside end surface 122). All dimensions can be changed depending on the installation dimensions of the window and other parameters.

The second side section 130 has a wall thickness of approximately 4-8 mm (thickness) with a length of approximately 10 cm (starting from the end face 113 of the support section 110 in the direction of the first side section 120) and a height of approximately 12 cm (Distance from the bottom to the top 133). The outline of the second side section 130 is cuboid.

The individual sections of the sealing device 100 according to the invention in the form of the support section 110, the first and second side sections 120, 130, the bench support section 140 and the step section 150 are described in detail below. The main focus is on 1 to 12 Reference, which show the sealing device 100 according to the invention in isolation. The intended installation state of the sealing device 100 according to the invention is then described with reference to FIG 13 to 25 described.

Support section 110

The support section 110 comprises on the upper side the first sealing surface 111, an end surface 112 pointing to the outside, an end surface 113 pointing to the inside and a side connection surface 114 for connecting a connector. The support section 110 is designed to support the window frame 200 below it and optionally has at least one reinforcing element in order to divert the load of the window frame onto the ground (crossbar of the wall opening). The reinforcing element can, for example, be cylindrical and penetrate the support section 110 from a top to a bottom. Preferably, several such reinforcing elements are arranged at regular intervals in the transverse direction along the support section 110. Alternatively, the reinforcing element can be designed in the form of a strip and penetrate the support section 110 in the transverse direction parallel to the underside of the window frame 200.

First side section 120

The first side section 120 is formed in one piece or monolithically with the support section 110 and adjoins the support section 110 on the outside. The second sealing surface 121 is located on an end face of the first side section 120 facing the support section 110. Furthermore, the first side section 120 comprises an end face 122 facing away from the support section 110, a side face 123 facing the bench support section 140, a side end face 124 facing away from the bench support section 140 and an upper side 125.

Second side section 130

The second side section 130 is designed as a plate-shaped body with a rectangular outline and a wall thickness of 6 to 8 mm made of a harder material than the first side section 120. A moisture-resistant plastic, preferably PVC, is suitable as the material for the second side section 130. In an extension of the first side section 120, the second side section 130 directly adjoins the support section 110 laterally. The second side section 130 is glued to the first side section 120 and to the support section 130 and to the step section 150 which is adjacent on the inside. The third sealing surface 131 is located on a side surface facing the support section 110. On the side facing away from the support section 110 there is a side end surface 132. The second side section 130 is arranged in a receptacle formed by the support section 110 and the first side section 120 such that the side end surfaces 124, 132 and top sides 125, 133 of the first and second side sections 120, 130 are flush with each other ( Fig. 3 ). Furthermore, the side end surface 132 of the second side section 130 merges flush with the side end surface 152 of the step section 150 that is adjacent on the inside.

Bench support section 140

The bench support section 140 connects on the outside to the support section 110 and laterally to the first side section 120. In this case, the top-side support surface 141 of the bench support section 140 is offset in a step-like manner downwards from the first sealing surface 111 of the support section 110, so that a window sill 300 (see FIG. 13 to 25 ) is covered in sections by the window frame 200 when the window frame 200 is sealed against the three sealing surfaces 111, 121, 131 as intended. The bearing surface 141 drops off to the outside, so that water can flow off to the outside.

On the upper outer edge, which faces away from the support section 110, the bench support section 140 has a water drip structure, which can be implemented in different variants. In a first variant, the water drip structure is designed as a profile lug 142. A vertical surface extends downward (approx. 1 cm) from the upper outer edge (water drip edge) of the bench support section 140. This is followed by a diagonal surface which extends inwards to an end face 145 of the bench support section 140. The end face 145 is subsequently clad with a plaster 610 to be applied (see Fig. 16 ), which can be pulled off the profile lug 142. In a second variant, the bench support section 140 comprises an incorporated extension plate 143, which protrudes beyond the end face 145 of the bench support section 140, runs flush with the support surface on the upper side and is coated with a continuous coating. In a third variant, the bench support section 140 comprises a profile angle 144, the upper leg of which extends flush with the support surface 141 on an upper side and protrudes beyond the end face 145 of the bench support section 140. A lower leg of the profile angle 144 lies essentially against the end face 145 of the bench support section 140. The end face 145 of the bench support section 140 and the lower leg of the profile bracket 144 lying thereon are covered with a fabric reinforcement 147, to which the plaster 610 is subsequently applied.

Step section 150

The step section 150 adjoins the support section 110 on the inside and forms a support surface for an inside window sill 500 ( 13 to 25 ). The end face 151 of the step section 150 faces inward, ie in the opposite direction to the end face 145 of the bench support section 140. A side end face 152 of the step section 150 and the side end face 132 of the second side section 130 are flush with one another. On the opposite side, a side pad 153 goes for connection of a connecting piece flush into the side connection surface 114 of the support section 110.

Profile angle 160

The profile bracket 160 made of metal reinforces the transition area between the first side section 120 and the bench support section 140. In the present exemplary embodiment, the profile bracket 160 has a C-profile, with a lower leg 161 of the profile bracket 160 on the support surface 141 of the bench support section 140 directly adjacent to the Side surface 123 of the first side portion 120 extends. A back 162 of the profile angle 160 extends upwards on this side surface 123 of the first side section 120. The lower leg 161 and the back 162 are glued to the respective contact surfaces 141 and 123, respectively. A thigh 163 of the profile bracket 160 extends parallel to the lower leg 161 of the profile bracket 160 and parallel to the support surface 141 of the bench support section 140 away from the side surface 123 of the first side section 120. The profile angle protrudes on the outside or on the side facing away from the window frame 200 via the first side section 120 and ends at the water drainage edge of the water drip structure. On the side facing the window frame 200, the profile angle 160 ends flush with the second sealing surface 121.

The profile angle 160, in cooperation with a suitable counterpart in the other lower corner region of the wall opening, forms a guide for inserting the window sill 300 into the intended position on the bearing surface 141 of the bench support section 140. The weight of the window sill 300, which can be made of stone, and the possibly loaded by additional weight, derived and distributed on the profile angle 160. This prevents direct contact of the window sill 300 with the support surface 141, so that scratches or the like on the support surface 141 of the bench support section 140 can be prevented.

Basic body and materials

In the preferred embodiment, the support section 110, the first side section 120, the bench support section 140 and the step section 150 form an integrally or monolithically formed base body with a porous or fibrous structure. The base body is preferably machined from solid material, for example milled. The bench support section essentially consists of insulating material, preferably expanded polystyrene (EPS), extruded rigid polystyrene foam (XPS) or soft wood fiber (HWF).

Coating 700

The coating 700 represented by dots (see Fig. 26 ) coherently covers the first, second and third sealing surface 111, 121, 131, the support surface 141 of the bench support section 140, the end face 112 of the support section 110 facing the support surface 141 of the bench support section 140 and the side surface 123 of the first side section facing the support surface 141 of the bench support section 140 120. The coating 700 is produced from two components and penetrates into the porous or fibrous structure of the base body to a penetration depth of approximately 5 to 15 mm. After chemical hardening, which can optionally be accelerated thermally, the coating forms a smooth, water-impermeable and glass-hard surface. The coating is UV-resistant and insect-resistant.

Fig. 26 shows representative of all coated sections of the porous base body a schematic sectional view of the support section 110 of the sealing device 100, wherein the coating 700 penetrates into the porous structure of the support section 110 and forms a smooth, glass-hard surface, which simultaneously represents the first sealing surface 111. In the present case, the porous structure of the support section 110 has a pore size of approximately 3 mm, which corresponds to the size of the EPS (styrofoam) particles. In the schematic sectional view of the Fig. 26 It can be seen that the coating penetrates approximately up to three times the pore size (approx. 10 mm) into the porous structure of the support section 110 and fills the gaps, so that the porous structure of the support section 110 is mechanically solidified in the region near the surface. The coating 700 can also be applied to non-porous structures (eg third sealing surface 131) in order to form a coherent surface with an adjacent coating 700 of a porous structure.

Arrangement (Fig. 13 to 25)

The arrangement according to the invention comprises, in addition to the sealing device 100, which with reference to FIG Figures 1 to 12 a window frame 200, a window sill 300 and at least one seal 400.

Some features and advantages of the sealing device 100 and arrangement according to the invention are summarized below as follows:
In both wood and solid construction, over-insulation of the window frame 200 in windows and doors is fundamentally necessary in order to eliminate thermal bridges. Sheet 2 of the standard catalog requires 3 cm of insulation. In the wall opening, however, there is always a distance between the wall and the window frame 200, which is usually foamed with polyurethane. As a rule, the window frame 200 is glued on via compriband and foamed at the bottom. Sealing tapes (5-7 cm wide) that are offered industrially make more sense will. Due to the diffusion gradient towards the outside, attention must be paid both to the sealing of the window frame 200 to the wall and to the sealing to the front. The compriband usually serves as an additional seal so that no water runs into the insulation.

The sealing device 100 according to the invention analogously forms a watertight receptacle for the window frame 200 in order to seal it downwards (first sealing surface 111), forwards (second sealing surface 121) and to the side (third sealing surface 131). This recording is made possible by a 4-10 mm thick, moisture-resistant plastic plate material, which is arranged laterally between the longitudinal edge side 230 of the window frame 200 and the wall opening and with the underside and front (first and second) sealing surfaces 111, 121 a coherent, lateral (Third) sealing surface 131 provides. This plate (second side section 130) is preferably made of PVC or other materials that have the required strength. Since the thin side plate fits between the wall opening and the longitudinal edge side 230 of the window frame 200, the seal 430 can be continued laterally and below (seal 210) of the window frame 200. On the basis of the sealing device 100 according to the invention, the seal 400 (410, 430) can thus be carried out continuously to the side and below the window frame 200, for example by means of a sealing tape or compression tape. The transition between the insulation and the side wall is therefore solved by the thin side plate. In particular, it seals the transition to the reveal. The sealing device 100 according to the invention analogously forms a trough which collects incoming water and drains it off in a targeted manner. When using a sealing tape, water can no longer get in through any gaps over the window. In particular, water is prevented from running laterally into the wall opening and further inwards towards the wall.

The bench support section 140 is offset in a stepped manner in relation to the support section 110 in order to receive a window sill 300 made of stone or aluminum, which runs in under the window frame 200 and is overlapped by the latter. A stone windowsill 300 (see Fig. 14 ) runs smoothly under the window frame 200, for example, while an aluminum window sill 300 generally has a holding rib at the inside end, which is held in the first or second groove of the window frame profile on the underside (see FIG. Fig. 13 ).

To adapt the sealing device 100 according to the invention to the reveal, a reveal corner part is placed on the molded body (= base body + second side section 130). The molded body can be adjusted depending on the reveal strength. The base body of the molded body preferably consists of expanded polystyrene foam (EPS). If insulation is used with soft wood fiber, the base body of the molded body can also be made of soft wood fiber, for example are manufactured. It is also possible to design the base body of the molded body from extruded rigid polystyrene foam (XPS). However, unlike EPS, XPS is not available as a block product, so that the basic body is complex to assemble from individual elements.

The insulation materials and materials mentioned are generally soft and can be plastically deformed even by low pressure loads. In order to prevent resulting material and functional damage, the molded body is protected according to the invention by the coating 700 (see FIG. Fig. 26 ). The coating 700 is waterproof, high-strength, UV-resistant, environmentally friendly, insect-resistant and made up of two components.

The basic body made of EPS or soft wood fiber is based on the insulation materials used all around and is deliberately soft and porous in order to achieve the required insulation effect. If the molded body were too hard overall, it would not optically integrate into the surroundings made of insulating materials and would visibly differ from it.

According to the invention, the coating 700 can be applied in such a way that it penetrates into the porous base body in order to solidify the base body starting from the surface. A varnish (approx. 100 µm) would never achieve the same strength and would flake off under load. Therefore, preferably no paint is used. The coating preferably penetrates to a depth of approximately 10 mm into the porous base body. After thermal curing, the coating is hard on the surface. As a result, essential properties of the insulating material are retained despite the surface hardening.

The lateral profile angle 160 (optional) should prevent the plaster 610 from standing in the water. The plaster 610 should therefore end at the thigh 163 of the profile angle 160. The coating 700 ( Fig. 26 ) is pulled up behind the profile angle 160 on the side surface 123 facing the bench support section 140. The back 162 of the profile angle 160 is glued to this side surface 123. The lower leg 161 of the profile angle 160 protrudes from the side surface 123 of the first side section 120 along the support surface 141 of the bench support section 140. By gluing the lower leg 161 to the support surface 141 of the bench support section 141 and by gluing the profile back 162 to the side surface 123 of the first side section 120, this area is considerably strengthened and crack formation in the angular area is prevented. The lower leg 161 of the profile bracket 160 additionally enables a guide for the window sill 300, so that contact between the window sill 300 and the bench support section 140 is prevented. The profile angle 160 accordingly provides mechanical corner and angle stability in the transition area between the bench support section 141 and the first side section 120 brought about. The lower leg 161 also keeps the window sill 300 at a distance from the support surface 141, so that an intermediate space is created through which penetrating water can flow off. The window sill is fixed to the support surface 141 of the bench support section 140 with individual adhesive points, but these do not impair the water drainage.

In the case of an aluminum window sill 300, the side flange is always lower than the window sill 300 itself. There is therefore a height offset. In order to prevent the lateral material from being pressed into the molded body, it makes sense to support the material laterally through the lower leg 161 of the profile angle 160.

The water draining structure 142, 143, 144 on the upper outer edge (water draining edge) of the bench support section 140 has the aim of draining water and guiding it over the plaster 610. This water draining structure 142, 143, 144 also increases the corner and stability of the bench support section 140 on the upper outer edge considerably.

The load transfer of the window frame 200 is regulated by the so-called goods directive. At the lower end of the wall, loads are transferred via load transfer points, which is nowadays accomplished by plastic blocks. In timber construction, a (wood) bar carries the weight of the window. According to the sealing device 100 according to the invention, holes for reinforcing elements can be introduced into the support section 110 at the intervals required by the assembly guidelines. Alternatively, a continuous plate (preferably recycled PU) can be placed under the window. However, it is disadvantageous that in this case the molded body has to be constructed in several parts and, for example, cannot be made from solid material. With floor-to-ceiling elements, reinforcement elements in the bench support section 140 are also possible, for example.

The term "window" refers to windows and / or doors without any further distinction between windows and doors in the context of this description.
