The invention relates to a floor distributor for hot water heating systems in buildings For connecting radiators to risers with two equal-sized, elongated, one above the other Housings, one of which encloses a flow chamber and the other a return chamber, on rectified Schmalseitenwändcn of the housing each a substantially horizontal flow chamber connection or return chamber connection is arranged for connection to the risers and furthermore the flow and return chambers are provided with distributor connections.

In the conventional installation of hot water heating systems, the radiators are connected to one another via risers via an extensive distribution network located in the basement, which may be divided into individual heating groups. These risers are arranged on the outside walls of the building, since the radiators are expediently arranged on the window front. In modern construction technology, however, the outer walls of the building often consist of relatively thin concrete stems as well as window and parapet elements. As a result, it becomes more and more difficult to pull up the necessary pipelines at the places on these outer walls that are most favorable for the radiators. A distributor arranged in the wall for underfloor heating is known from DT-Gbm 72 46 356. ^6s

With the already known laying of ring lines under the ceilings, where the radiators are coated with heating agent through the floor, on the other hand, is a high material and assembly cost necessary.

A floor distributor of the type mentioned at the beginning was therefore already known to remedy this deficiency (Heaiing. Piping & Air Conditioning magazine, October 1969. pp. 67 to 69).

In this known floor distributor for hot water heating systems, the flow and return are arranged above the floor and they hen from the wall or are in a wall recess used, and the manifold connections are perpendicular to the housings of these chambers Floor straightened. The number of pipelines that can be connected is relatively small or must be Correspondingly long flow and return chambers can be used if there is a larger number of connections should be provided. Are the Vor and Rücklaurkammern embedded in the wall, a relatively large recess must be provided in the wall, i.e. knocked out, which then has to be closed again. The flow and return chambers protrude freely in the room, such an arrangement is very space-consuming.

The invention is therefore based on the object. a floor distributor for hot water heating systems of the aforementioned type so that or easy to manufacture and space-saving in the floor can be installed and that a large number of distributor connections can be provided.

This object is to be achieved according to the invention in that in a flat design cuboid closely stacked housings of the flow and return chambers to the distributor connections at least one of the free longitudinal side walls of the flow chamber and one free longitudinal side wall of the The return chamber protrudes horizontally.

The flat, stacked housings are embedded in the floor. This can be done without difficulty can also be done in a finished house, with the pipes then being kept very thin can be guided along the lambrerie or at the edge of the floor and wall.

The floor distributor can therefore also be used when modernizing a heating system while maintaining it conventional radiators can be used. There are no special valves or other changes required on the radiators, as the pipes according to their function on the supply or the The radiator drain can be connected without crossing.

The distributor connections can according to a preferred Embodiment here on two opposing longitudinal walls of the flow chamber as well the return chamber be arranged symmetrically. In this way, compared with a known Distribution pipe of the same length with the distribution connections stand vertically, attach twice the number of connections without difficulty.

The distribution connections of the flow chamber be arranged offset with respect to the distributor connections of the return chamber. This will a space saving and low installation height achieved.

The invention is based on the drawings, in which an embodiment is shown, explained in more detail. It shows

F i g. 2 is a scientific perspective view

the possible relocation of a heating system with the floor distributor.

The floor distributor, generally designated V , consists of two housings 1 and 2 of equal size. Housing 1 encloses a flow canister la and housing 2 a return chamber 2a. The housings are arranged closely one above the other and are designed as relatively flat cuboids. Flow and return chambers la and 2a are connected separately to the corresponding risers 7 and 8 (FIG. 2). The connections 3 and 4 provided for this purpose are each arranged on the narrow side of the housing 1 or 2 and lead from the same side into the corresponding chamber, so that these flow chamber and return chamber connections are essentially horizontal and next to one another, only in different planes, lie. In this way, the distributor housing with the connections takes up the smallest possible space and offers a direct and shortest possible connection to the riser.

At least one free longitudinal side wall of the flow chamber la and the corresponding longitudinal side wall of the return chamber 2a are provided with distributor connections 5 and 6 for the connection of the pipelines R leading to the heaters H. In most cases, the floor distributor V will be symmetrical, as shown in FIG. 1 is shown. Here, the distributor connections 5 and 5 'of the flow chamber la and the distributor connections 6 and 6' of the return chamber 2a are arranged symmetrically on the opposite longitudinal side walls, whereby the distributor connections 5, 5 'of the flow chamber can be offset from the distribution connections 6, 6' of the return chamber. This again saves space and has an extremely low installation height. In addition, the pipes to the individual radiators are laid completely without crossing (Fig. 2).

The connections 3 and 4 for connecting the flow and return chambers la and 2a to the risers 7 and 8 can have an angular cross-section, but also any other useful cross-section.

The distributor connections 5, 5 ', 6 and 6' and the pipes leading to the radiators can have a small pipe diameter. An insulated one available in rolls is suitable for these pipelines Special pipe with the distributor connection .- n not welded, but connected by means of special pliers with clamp or press connections. This way of working means that all connections are concentrated in the smallest of spaces and can be easily monitored. There are no welded joints in the floor, whereby a great security against corrosion damage is given.

The installation of the heating system is carried out as follows: Depending on the size and extent of the floor plan, a few risers are raised. The number of risers is determined by the heating group division, which is determined by the direction of the compass or the occupancy of the floor. As a rule, a riser 7 and 8 will suffice for a dwelling. In any case, the risers can be led up and installed in the structurally favorable inner walls of the building. According to FIG. 2, the riser 7 and 8 is mounted next to the door opening T. The floor distributor V is in the floor immediately next to the. Risers let in. From the vestibule la leads de. ' Connection 3 to the riser 7 and from the return chamber 2a the connection 4 leads to the riser 8. The pipes R and R ' which lead to the individual radiators H are connected to the distributor connections 5 and 6 or 5' and 6 ' . The distribution terminals 5 and 5 'of the supply chamber la and attached here pipelines R are continuously drawn, while the switch ports 6 and 6' are drawn the return chamber 2a and the respective pipelines R and R dashed ', it can be seen that from a floor distribution V according to the number of distributor connections, pipes in the floor, ie on the raw ceiling of the floor, can be laid to the radiators H without crossing. The size of the floor distributor depends on the number of radiators to be connected. The pipe network in the basement is so small that the insulation effort is practically irrelevant.
