Description

The invention relates to a device for preferably subsequent and column-free attachment of a projecting support beam for example, a balcony, conservatory or the like to a building. Furthermore, the invention relates to a support beam for the device according to the invention and an arrangement of the device according to the invention and the support beam according to the invention.

Increasingly, the desire emerges to equip existing buildings with a balcony or conservatory retrospectively. Often there is also the desire not support the balcony or conservatory by means of supports, but the balcony or the conservatory cantilevered or self-supporting, so to install column-free to the existing building.

The attachment of a pillar-free balcony already in the construction of a new building is compared to the subsequent pillar-free attachment of a balcony to an existing building comparatively easy. For example, it is possible and customary to embed supporting parts for a balcony or conservatory during a new construction of a building, for example in a concrete ceiling, and then to fasten the balcony construction to these cast-in supporting parts.

Although constructions are already known in the prior art, which make it possible to install a balcony or conservatory also post-construction on a building without columns. However, these constructions are often complex and very expensive to produce. Furthermore, they often lead to undesirable thermal bridges, which is particularly disadvantageous in the context of awareness of sustainable development and the increase in the cost of energy and legislation on the thermal insulation of buildings. Furthermore, column-free constructions are usually associated with the disadvantage that their free end lowers down over time and a readjustment to align the balcony or conservatory again substantially horizontally, usually only with great effort is possible.

In view of the above, it will be apparent to those skilled in the art from this disclosure that there is a need to solve or overcome the above-described problems or disadvantages. This invention addresses this need in the art as well as other needs that will become apparent to those skilled in the art from this disclosure.

Fig. 1 shows a side view and Fig. 2 3 is a plan view of a device according to a first embodiment of the invention, which is provided to a cantilevered support beam B for preferably a balcony, Conservatory or the like to attach to an existing building. The device comprises a first holding member 10 for passing through a hole in an existing building exterior wall W and for attachment to or in a building ceiling D, whereby a building inside bearing L1 can be achieved. The first holding element 10 rests on the building ceiling D. On the first holding element 10, four fixing portions 11a are provided (two on each side), which are placed on the building ceiling D and each having an opening for a building ceiling fixing part 12a such as a dowel. Through the openings, a building ceiling fixing part 12a are guided in each case, which is fixed in the building ceiling D. As in particular in Fig. 2 5, the attachment portions 11a are disposed laterally on the first support member 10 and extend in the longitudinal direction of the first support member 10. The attachment portions 11a on one side of the first support member 10 overlap the attachment portions 11a on the other side of the first support member 10.

As further in the Figures 1 and 2 As can be seen, the device comprises a second fastening arrangement which is provided to be at least partially positioned in a recess in the support beam B and to secure a second support member 20, whereby a building exterior bearing L2 is achieved. In particular, the second fastening arrangement comprises an abutment block 13a. The abutment block 13a has an opening through which the second holding element 20 is guided and fixed by means of a securing or adjusting nut 37 on the abutment block. The first holding element 10 and the second holding element 20 are connected to each other in the connecting region V by means of a long nut and a lock nut. (However, it is also conceivable to dispense with the second retaining element 20 and only a single To provide holding element, which performs both the functions of the first and the second holding member). The abutment block 13a has a flat bottom portion and is arranged substantially free of space at the bottom of the support beam recess. On the abutment block 13a, two attachment portions 14 are mounted, which are placed on the support beam B and each having an opening. Through the openings in each case a support beam attachment part 15 are guided, which is fastened in the support beam B. The attachment sections 14 and the support beam attachment parts 15 are a position assurance for the abutment block 13 a and substantially do not contribute to the load transfer, whereas the attachment portions 11 a and the building ceiling fixing parts 12 a contribute to the load transfer from the first support member 10 in the building ceiling D.

Figures 1 and 2 further show a bearing assembly 30a, which is provided to be at least partially positioned in the building exterior wall W to define a receiving space for the support beam B and to support the support beam B from below. The bearing assembly 30a includes a first, lower flange 31a, a web 32a, and a second, upper flange 33a. The web 32a connects the first flange 31a with the second flange 33a, so that a substantially Z-shaped profile is formed. Further, one of two lateral connection plates 34 is seen connecting the first flange 31a, the web 32a and the second flange 33a. The receiving space for the support beam B is limited by the first flange 31a, the web 32a and the upper flange 33a and the lateral connecting plates 34 to provide a circumferentially closed-walled receptacle for the support beam B. The box-shaped receptacle produced in this way has the advantage that it can be put on front edge plaster and thus the plaster connection before assembly of the supporting beam is possible. Furthermore, a particularly strong bearing arrangement is achieved.

The first flange 31a is at least partially on the exterior wall W provided with plaster and serves as a support for the support beam B, wherein the second flange 33a at least partially rests on the building ceiling D between the building ceiling D and the building exterior wall W. The web 32a is facing a front side of the building ceiling D and an end face of the supporting beam B. Between web 32a and the front side of the building ceiling D a mortar layer M is provided. The bearing arrangement 30a, in particular the second flange 33a and / or the web 32a, has a passage opening for the first holding element 10, through which the first holding element 10 is guided, but without transferring forces to the bearing arrangement 30a. The first holding element 10 and the second holding element 20 are tie rods that transmit substantially exclusively tensile forces. The first holding element 10 and the second holding element 20 are provided to transmit substantially exclusively horizontal tensile forces between the building exterior side storage L2 and the building inside storage L1.

The bearing assembly 30a is provided to define a receiving space for the support beam B which is bounded below by the first flange 31a, rear by the web 32a and laterally by the two connecting plates 34. Thus, a strong, rigid bearing assembly 30a is achieved is box-shaped and is provided at least partially Z-shaped.

The first flange 31a is provided to transmit substantially vertical compressive forces to the building exterior wall W, with the second flange 33a being provided to extend substantially to transmit vertical compressive forces to the building ceiling D. The web 32a, in particular of the first flange 31a facing and thus lower web portion is provided to transmit substantially horizontal compressive forces on the building ceiling D. The second fastening arrangement, in particular the abutment block 13a, the first fastening arrangement and the first and second retaining elements 10, 20 arranged therebetween are preferably provided so as to have essentially exclusively horizontal (tensile) forces in the longitudinal direction P1 of the first retaining element 10 and of the second retaining element 20 take.

As further in the Figures 1 and 2 can be seen, the bearing assembly 30a and the first holding member 10 on an adjusting means, which is provided for securing the position of the bearing assembly 30a and to adjust the bearing assembly 30a when mounting the device can. The adjusting means comprises an adjusting nut 36 which is provided to be threadedly received by the first holding member 10 and to be screwed against the bearing assembly 30a, in particular the second flange 33a or the web 32a.

The in the Figures 1 and 2 shown support beam B has a longitudinal groove 40 extending from a first building side end face of the support beam B (in Figures 1 and 2 the right side) to a second, located at the free end of the supporting beam B front side (in Figures 1 and 2 the left side). At the free end of the second holding member 20, an adjusting device is provided to align the mounted support beam B substantially horizontally. The adjusting device comprises an adjusting nut 37, which is provided to be received in a thread-like manner by the second holding element 20 and to be screwed against the second fastening arrangement, in particular the abutment block 13a. The Adjusting nut 37 is accessible via the longitudinal groove 40 in the support beam B, from the free end of the support beam B, even in the assembled state of the support beam B readily. This is of particular advantage since, due to the cantilever-type or cantilevered arrangement, the mounted support beam B tends to bend somewhat downwards over time, which is particularly disadvantageous optically. About the longitudinal groove 40 freely accessible adjustment of the support beam B readjusted in a simple and fast way and the support beam B are again aligned substantially horizontally. Reference AB denotes a cover plank, which is positioned on the support beam B or over the longitudinal groove 40 and the recess in the support beam B.

The recess in the building exterior wall W for the bearing assembly 30a can be achieved by caulking. Before that, any existing masonry, any existing thermal insulation, etc. must be removed. Also by caulking and / or by means of flexible cuts, the space can be provided to provide the second flange 33a between the building ceiling D and the building exterior wall W disposed thereon. Any gaps between the first flange 31a, web 32a, second flange 33a, the mounting portions 11a and the building ceiling D can be compensated for example by means of synthetic resin mortar or concrete spatula to achieve a full-scale power transmission. The building exterior wall W can be provided, for example, with a 20 mm bore essentially on the upper edge of the building ceiling D, through which the first holding element 10 can be made from inside to outside. The fixing of the first fastening arrangement or the building corner fastening means 12a advantageously takes place inside the building in order to minimize the caulking work. With the length of the first retaining element 10 and / or the longitudinal and / or transverse extent of the fastening portions 11a can be reacted to structural conditions such as wall thickness, bricking, etc. in a simple manner. The bearing arrangement 30a can be mounted with the aid of backfilling compounds and aligned with the aid of the first retaining element 10 or the adjusting nut 36.
