DE29805143U1 - Balcony system with a building connection - Google Patents

Description

The invention relates to a balcony system with a building connection and a support device for supporting the preferably multi-storey balconies on the ground.

Especially in the case of old buildings, whose balconies no longer meet the static requirements after a few decades, the problem of subsequently adding balconies to existing buildings arises. The facades should be as small as possible.

be slightly impaired, and in any case the facades should not be opened up to allow larger supporting structures to be incorporated into the masonry.

However, with balcony systems subsequently attached to external facades, the problem arises that the unevenness of the facade must be easily compensated for during attachment and adjustment options parallel to the facade must be possible within narrow limits even with an existing overall structure, while at the same time vertical positions of the balcony caused by changes in the length of the supports must be compensated for without causing any constraints in the connection. Non-load-bearing layers (thermal insulation or facing bricks) must not be subjected to any load.

This object of the invention is achieved by making a core hole in the facade in which a depth stop sleeve is provided at the end with a threaded pin protruding into the hole. A connecting part, which has two threaded plates at its ends, is screwed onto this threaded pin. Since the connecting part has a smaller diameter than the core hole, the balcony is firmly attached to the house, particularly when two such connecting parts are used in a horizontal position next to each other to connect a balcony. On the other hand, however, if the length of the vertical supports changes due to the effect of heat on the balcony supports, this connecting part can tilt vertically by a few degrees without causing unplanned tensions. The space between the connecting part and the facade layer should be secured with an elastic material to prevent water from penetrating the facade.

In particular, it is proposed to provide the connecting part as a cylindrical element with two threaded plates that protrude above this element, whereby the inner threaded plate is round in a corresponding sleeve at the end stop and the outer threaded plate can also be made square as desired for connecting the balcony.

Further advantages and features of the invention emerge from the following description based on a preferred embodiment. It shows:

Fig. 1 shows a first embodiment of a building connection of the balcony system according to the invention,

Fig. 2 is a plan view of the connector from Fig. 1, and

Fig. 3 a variant of the building connection for a balcony system

The building connection shown in Fig. 1 is used for balcony systems that essentially stand on supports, which in turn are firmly anchored to the ground beneath the balcony, thus only transmit tensile/compressive forces horizontally into the masonry.

Without extensive destruction of the facade, in particular of any layer 38, a core hole can be made into the solid masonry 4 0 to accommodate a connecting part 10 with little impact on the facade. This connecting part 10 has two threaded plates 12, 14 and at least one connecting piece 15.

the body 30. The balcony is rigidly connected to one threaded plate 12 using screw bolts 26, while the other threaded plate 14 is firmly mounted at right angles to the masonry using a screw spindle 18 provided in a sleeve 16.

The screw spindle 18 and the sleeve 16 are firmly anchored in the masonry by means of adhesive or binding agent 32. Furthermore, an end plate 20 of the sleeve around the spindle can be used as a depth stop. The screw spindle 18 can be firmly screwed into the sleeve 20 or, as shown in Fig. 3, can be supported by a nut 22 arranged behind the plate 20. By selecting a diameter of the body 30 that is smaller than the opening diameter of the sleeve 16, with the opening of the sleeve 16 essentially completely filled by the plate 14, it is possible to allow a tilting movement of the connecting part 10 in the core hole by a few angular degrees.

This tilting is important because the change in length of the vertical supports of a balcony system would otherwise create constraints on the plaster 38, which would lead to damage. By providing elastic compensation material 34 around the body 30 in the core hole, in particular in the plaster material 38, it is now possible to create a weatherproof seal that still allows compensation even in the event of a change in temperature. On the other hand, the possibility of moving the body 30 on the screw spindle 18 also makes it possible to subsequently adjust the position of a balcony. To this end, it is conceivable to create appropriate access points for special tools on the outside of the threaded plate 12 or to do this at an angle.

Fig. 2 shows a top view of a round version of the threaded plate 12, with the central opening for the screw 26, through which one can see the bolt 18, which is anchored in the masonry.

Alternatively, it is also possible, as shown in Fig. 3, to create a connection with a screw 28 in a plate 12 that is not a threaded plate but merely a plate with a smooth-walled through hole 36, in which a direct contact between the screw 28 and the screw spindle 18 is possible via an intermediate part 24. In this case, the part 24 is fixed within the body 30 by means of a nut 29. In this case, a heat-induced vertical length change can also be absorbed.
