House connection box for wall installation.

The innovation concerns a house connection box for wall installation according to the generic term of protection claim 1.

Such house connection boxes, also known as wall-mounted ICable house connection boxes and referred to below as WKH, serve as a transfer point from the public distribution network to the consumer system. The fuses arranged in the WKH protect the lines/cables against overload and short circuit.

WKH are installed in the outside of building walls to allow representatives of the electricity supply company, whose area of responsibility includes such electrical system components, access at any time, regardless of the customer's presence.

Due to the niche in the building's outer wall required for the installation of the heat recovery system, the thermal insulation in this area is reduced, so that condensation occurs on the inside of the building's outer wall, which can lead to dark streaks and the formation of mould.

In order to eliminate such disadvantages and to equalize the thermal bridge, polystyrene panels are arranged between the bottom of the wall box and the niche wall in order to increase the thermal resistance of the assembly, consisting of the remaining wall of the building's outer wall, the housing floor, the air layer and the door _, to the value specified by the wall.

The aim of the innovation is to design a thermal insulation system in such a way that the required thermal insulation can be achieved using simple means.

This problem is solved according to the innovation by the characterising part of claim 1.

Advantageous embodiments of the innovation are the subject of the dependent claims.

The advantage of the new house connection box is that it increases the thermal insulation and also has the advantage that the house connection box is firmly connected to the masonry.

An example of the innovation is explained using the drawings.
It shows

Fig. 1 a section through the building's outer wall with the WKH installed in the niche, the side wall of which is shown broken open in the lower area;

Fig. 2 shows the front view of a part of the building's external wall with the WKH installed and ready for use, the door and frame of which are shown broken out in a partial area.

On the building's outer wall 1, a niche IC and a channel for the supply and drainage lines are formed.

The wall box 2 of the WKH is inserted into this niche IC and locked in the intended position. The wall box 2 is equipped with a circumferential bulkhead 4 arranged parallel to the plaster edge, which is fixed in position by stops 4A.

The sealing foam 5 is injected through the openings 2Al arranged on the plaster edge 2A, which foams up and hardens between the plaster edge 2A and the bulkhead, so that a tight seal is achieved between the wall box 2 and the masonry or the external plaster IA, which ensures the desired thermal insulation and at the same time firmly connects the WKH to the masonry .

The lines/cables to be connected, which are connected to the fuses 6, are located in the cable ducts installed in the masonry.

The lower end is formed by the frame 3A, which is removably attached to the wall box 2, with the door 3 arranged on it.

The sealing foam 5 inserted between the bulkhead 4 and the plaster edge 2A increases the thermal resistance to the value of the unperforated external building wall, so that it is ensured that no condensation can occur on the interior plaster IB of the external building wall 1.
