Description

System and method for sealing an empty can in a wall

Technical area

The invention relates to a system and method for sealing an empty can in a wall according to

independent claims. The invention also relates to an elastic sleeve for use in such a system and to a method for producing a sleeve according to the invention in accordance with the further independent claims.

State of the art

In the wind and airtight production and design of rooms, especially in renovation and renovation buildings, is usually a so-called wind paper on the building exterior side and a

Airtightness paper or a vapor barrier applied on the inside of the building. In the case of subsequent electrical installations, in particular with recessed cans, empty cans, electric drop-off boxes, distribution boxes, etc., however, the air-sealing layer must be separated again. Therefore, numerous seals are already known from the prior art to the connection between the empty or installation boxes

seal.

CH698127 describes an installation box for electrical purposes, in particular it is a mounting box or a

Cavity wall socket. In particular, it is proposed that the design is formed by at least one perforation whose diameter is closely adapted to the empty conduit, cable or the like to be passed through, and that at least the perforation is provided by a layer of soft material

Material, in particular plastic material, is closed, which can be punctured by the empty pipe or cable durchzusteck.

DE10333499 relates to a cable feedthrough plate with a rigid frame, the at least one frame opening for passage a cable, and having a cross-section of the frame opening spanning elastomeric partition wall having a passage opening for the cable. There is a stopper through which the

Can be closed frame opening.

CH43441 1 relates to an electrical installation box, in particular a Unterputzeinlasskasten, with at least one intended for the introduction of a pipe body. The tube insertion point has a splinter- and crack-free puncture membrane whose

Cross-sectional thickness from the center of the membrane against the

Periphery is steadily increasing.

EP1986299 discloses a box for electrical cables in walls.

The basic problem with these embodiments, however, is that the draft of air between the empty can and the bulge or the opening which projects into the wall or insulation layer is still given in particular in the case of building outer walls, since the

Airtightness paper is broken through. A clean seal through the tightness paper is disadvantageously very time consuming and therefore costly.

Presentation of the invention

It is an object of the invention to provide a system in which, in particular, the draft of air between an empty can and the sinking in the wall in which the empty can is prevented.

It is another object of the invention to provide a method in which the draft between an empty can and the cost

Subsidence in the wall, in which the empty box is located, is suppressed. This method should in particular be less time-consuming and easy to implement. According to the invention, this object is achieved in a system according to the preamble of claim 1, characterized in that between the empty box and the masonry is an elastic sleeve, through which the or the empty tubes are guided, wherein the points at which the or the empty tubes through the Cuff are guided, reinforced by support rings and sealed, and wherein the elastic sleeve is attached to the outer edge of the opening with a fastening tab.

These objectives are also achieved in a method according to the independent method claim.

Advantageously, the elastic sleeve is glued to the outer edge of the opening on the insulating layer or the tightness paper with the fastening tab. The cuff can advantageously consist of latex, silicone or rubber and several support rings can in

different sizes and diameters in the cuff

Implementation of conduits in different sizes and diameters to be incorporated. The fastening tab and the support rings may be made of a thin and flexible or rigid polyurethane, PVC or CA (cyanoacrylate) hinge-sheet plastic.

The objects of the invention are achieved by an elastic sleeve and by a method for producing such a sleeve according to the independent method claims.

Advantageously, the opening in the wall is completely sealed by the existing invention. Through the cuff can not

Draft between the empty box and the opening in the wall or between the conduits and the cuff arise as the

Cuff has a corresponding sealing effect. The cuff according to the invention and the system according to the invention make it possible in particular for the draft of air to pass through the air or air

Windproof layer is formed and circulated behind the interior trim and, for example, in the skirting area in the living area on or exits prevented. It also has no optical disadvantages, as the Empty box and wall covering completely covers the cuff and its gluing.

Further advantageous embodiments are in the

Subclaims specified.

Brief description of the figures

The invention will be explained in more detail with reference to the appended FIGURE, which shows an overall view of a system according to the invention.

Ways to carry out the invention

The inventive system 1 for sealing an empty can 7 in a wall is shown in the single figure. The wall consists of a masonry 2, one located on the masonry 2

Insulation layer 3, a located on the insulating layer 3 wind or airtightness paper 4 and an inner lining thereon 5. Between the inner lining 5 and the

Tightness paper or the insulating layer 3 may be a smaller or larger construction and / or processing-related air gap. Parquet 6 or another floor covering, for example, adjoins the inner lining 5 on the ground. The wind or impermeable paper 4 is normally glued underneath the floor covering and due to the system. The masonry 2 may be in particular a building outer wall.

In the wall is a hole, a sink or an opening into which the empty box 7 is inserted. The sinking in the wall extends in the example shown into the insulating layer 3, wherein the leaktight paper 4 is severed. The sinking can also extend to the masonry. From the masonry and or from the insulation layer are or are during the installation of the empty cans 7 different conduits 8 or cable (for example, electrical

Installations) through openings 71 in the empty box 7 out. According to the invention, there is now an elastic sleeve 9 through which the empty tube or conduits 8 are guided between the empty box 7 and the insulating layer 3. This elastic sleeve 9 is made of a flexible and very stretchable material such as latex, silicone, rubber, etc. The sleeve 9 corresponds in shape to a bag which is slightly larger than the product to be mounted below, on one side of which an opening slightly larger than the following assembly product (such as the empty box 7, the opening in the wall, etc) is incorporated. It is generally here empty cans 7

used, as they are common for switches or sockets. In the context of the invention, however, can generally be submerged boxes, boxes for electric sheets, junction boxes, etc. The size of the cans does not matter, the inventive sleeve 9 is designed according to the size of the opening. The elastic sleeve 9 is at the outer edge of the opening in the wall on the insulating layer 3 or the

Tightness paper 4 attached with a circumferential fastening tab 91 and is preferably glued there. The gluing can be done by the tab 91 being self-adhesive, in which double-sided adhesive tape has been applied to the tab 91, or that the tab 91 is adhesively bonded from the outside with an adhesive tape. The

Fastening tab 91 is preferably approximately perpendicular to the bag and is made of the same material. In the circumferential fastening tab 91, a thin, flexible or rigid polyurethane ring, PVC ring or CA hinge sheet ring is incorporated in the preparation of the cuff, the sleeve opening the intended or required shape (round, square, etc.) the subsequently to be assembled parts (such as the empty box 7) and a corresponding rigidity. In the sleeve 9, additional thin, flexible or rigid support rings 92 made of polyurethane, PVC or CA hinge sheet are incorporated in a laminating manner during the manufacturing process. The support rings 92 ensure that the introduced empty pipe is uniformly enclosed and sealed by the elastic sleeve material even under strong sideways load (pull / push). The inner diameter of the support rings is slightly larger than the duct or cable to be performed and the outer diameter is selected so that a sufficient stability of the support rings is present. Several support rings 92 in different sizes and diameters are according to the Tube diameter variable incorporated in the sleeve 9. The incorporated support rings 92 should not touch and have a predetermined distance from each other, so that the flexibility of the entire sleeve is still guaranteed.

Instead of the support rings at the intended

Implementation points for cable pipes or pipes, is used in the

Making the cuff the required stability thereby

ensures that a ring-like bead during the

Manufacturing process of the cuff is made of the same material. This bead is a thickening of the material in the required places.

According to the invention, within one or more support rings 92 in the center, the latex layer is perforated or perforated around the or the inner diameter corresponding to the empty tubes or cables

perform. When carrying out the corresponding pipes or cables encloses now, the existing within the support rings latex, the performed conduits and cable air and windproof with the

desired voltage.

The invention also relates to a method for sealing an empty box 7 in the wall described above. First, an opening or sinking is introduced into the wall already mentioned, in which then an empty box 7 is inserted, wherein one or more conduits 8, which come from the masonry or from the insulating layer, are guided into the empty box 7. According to the invention, however, before the insertion of the empty box 7 and before attaching the

Interior trim, the cuff can be used even with fully assembled linings, on the wall, the elastic sleeve 9 inserted into the opening, at the same time or the conduits 8 are guided by the sealing support rings 92 of the sleeve 9, and wherein the elastic sleeve. 9 is attached to the outer edge of the opening on the insulating layer 3 or the tightness paper 4 with the fastening tab 92. The process step of introducing the sleeve 9 is advantageous in a few steps and with low time required. According to the invention remain, due to the given elasticity and mobility of the cuff, all performed conduits and or cables in any direction and flexible. They can be pushed back or tightened if necessary, which is particularly important and claimed in subsequent operations, installation of the empty box, etc.

The invention also relates to a sleeve 9 and a method for producing such a sleeve 9 with support rings 92 and fastening tab 91. Since the sleeves 9 can be prefabricated, they are advantageously already available for the installation of the cans during renovation and renovation work and other electrical installations. They can thus be used in a few minutes in the opening and glued.

Advantageously, the opening in the wall is completely sealed by the existing invention. Through the sleeve 9, no draft between the can 7 and the opening in the wall and between the conduits 8 and the sleeve 9 arise because the sleeve 9 has a corresponding sealing effect. It also has no optical disadvantages, since the empty box 7 and later the inner lining 5 completely covers the cuff.

The invention is not limited to the embodiment but in the context of the disclosure and the claims often variable.
