Description

The invention relates to a base plate module for raised floors, comprising an air space, is passed through the air to be heated or cooled.

In known cavity floors a spacer plate, which comprises a plurality of distributed over the surface spacer elements, placed on a subfloor, the spacer elements stand up on the subfloor. On the top of the spacer plate tubes for passing a cooling or heating means are placed before then poured onto the top screed, the u. a. also enters the spacers and thus prevents compression of the spacer plate. Between the spacer plate and the subfloor an air space is formed, is passed through the air. The spacer plate acts as a heat exchanger through which heat or cold is transferred from the pipes to the air, before the air is then passed through an air outlet in the room to be heated or to be cooled.

In known cavity floors, the spacer plates, the feed devices for the supplied air and the air outlets are mounted individually. The assembly is thereby very complex and there is often the problem to keep the individual components during the pouring of the screed in the predetermined orientation. The installation of such cavity floors is thus possible only by appropriately trained and qualified personnel.

A spacer plate with advantageous grooves and nubs, in which the tubes are arranged for the cooling or heating means and which surround the tubes at least half, is from the document EP 1 087 182 B1 known.

It is an object of the invention to provide a bottom plate module for raised floors, with the help of a particularly simple installation of the cavity floor is possible.

This object is achieved by a bottom plate module having the features of claim 1. Advantageous developments of the invention are specified in the dependent claims.

According to the invention, the base plate module comprises a base element and a spacer plate, which has distributed over its surface arranged spacer elements which contact the bottom element. Further, the bottom plate module has four side members, which together with the bottom member and the spacer plate define an air space, which serves for the passage of air to be heated and / or to be cooled. The bottom plate module has at least one air supply opening for supplying air to the air space and at least one air outlet opening for leading out the heated or cooled air from the air space. Furthermore, the bottom plate module has at least one connector for producing a plug connection with a complementary connector of another bottom plate module.

Such a floor panel module ensures that the individual elements of the cavity floor do not have to be mounted individually, but all are already integrated in the factory in a base plate module. Due to the modular construction is further achieved that the size of the cavity floor and the performance of the heating or cooling can be adapted by simply mating a different number of such bottom plate modules to the individual circumstances.

In particular, it is achieved by the simple plugging together of the modules that the assembly can also be carried out by untrained persons, in particular DIY hobbyists. This makes it easy, fast and safe to plan and install the entire ventilation system without the need for special expertise.

In a particularly preferred embodiment, the spacer plate as a spacer elements frustoconical depressions, which depressions rest on the bottom element. Further, it is advantageous if the spacer plate designed as grooves and / or studs holding elements for holding pipes for a heating and / or cooling medium and when the grooves are formed in the spacer plate to the same side as the wells. The grooves are preferably designed such that the pipes to be laid are enclosed on at least half of their circumference by the respective grooves.

This ensures that as much heat or cold is discharged from the pipes to the spacer plate and from this again to the air flowing through the air. This achieves effective heat exchange and as little heat or cold as possible is lost. In particular, therefore, a rapid change of the desired temperature of the guided through the cavity floor air can be done to increase the power transfer.

It is in particular a spacer plate with the features of the spacer plate of one of the claims of the European patent application EP 1 087 182 B1 used, the contents of which are hereby incorporated by reference.

It is also advantageous if the air inlet opening is formed as an opening in one of the side elements. In particular, a plurality of openings, in particular three openings, are provided in the side element, through which the air can be supplied to the air space of the base plate module. This ensures that the most uniform possible flow of air over the entire width of the air space, so that it flows through evenly and thus much heat or cold can be discharged from the spacer plate on the frusto-conical recesses in the air.

The air outlet opening is arranged in particular on the side of the base plate module, which is opposite to the air inlet opening, so that the bottom plate module is completely flowed through by the air and thus a correspondingly efficient heat exchange takes place.

In particular, two types of bottom plate modules are provided, a so-called base module and a so-called supplementary module. In the base module, the air outlet port is formed as an air outlet disposed on the side of the spacer plate for discharging the air to the space to be ventilated. In particular, this air outlet comprises a mesh installation box, an expanded polystyrene (EPS) block placed in the mesh box, which provides stability to the mesh box, and a grid which is inserted into the mesh box and covers the opening of the air outlet. The heated or cooled air is delivered to the room via this air outlet.

The air outlet is in particular designed such that it extends over the entire width of the base module. In particular, the air outlet is designed such that the air flowing into the room as a source ventilation with a comfort-increasing air velocity, in particular of about 0.2 m / s, is formed. Thus, unpleasant drafts are avoided, which occur at usual air outlet speeds of significantly more than source ventilation speeds, in particular of more than 1 m / s.

On the other hand, in the supplementary module, no air outlet is provided for ventilating the room, but instead, at least one opening in a side member is provided as an air outlet opening, this side member being opposed, in particular, to that side member in which the air supply opening is formed. The air outlet opening is in this case designed such that it can be connected to the air supply opening of another bottom plate module, in particular a base module or a supplementary module. The supplementary modules can thus be connected to each other as desired and to the base module, so that the number of base plate modules used can be adapted in each case to the room size and the necessary heating or cooling capacity.

In particular, a plurality of air outlet openings are provided in the side member, which are distributed over the entire width of the side member, so that the most uniform possible air outlet from the supplementary modules is possible.

In particular, the supplementary modules have the same number of Luftzuführ- and air outlet openings, which are each designed and arranged so that two such supplementary modules can be plugged together so that each covers an air supply opening with an air outlet and thus achieves a secure, seamless forwarding of the air becomes.

The connector, via which the bottom plate modules can be connected to one another, is designed in particular as an air channel (tube) projecting from the air feed opening, which can be inserted into the air outlet opening of another bottom plate module, in particular a supplementary module. Thus, it is achieved that is given by a simple insertion of the air duct in the corresponding opening of the other base plate module, a connection between the bottom plate modules and they can thus be mounted very easily. In addition, this design also ensures that no air can escape from the interface between the bottom plate modules, but that it can be safely transported between the bottom plate modules.

Furthermore, it is advantageous if the bottom plate modules, in particular the supplementary modules, also at at least one air outlet opening have a further projecting air duct (pipe) which can be inserted into the air inlet opening of another bottom plate module for producing a plug connection.

In particular, it is advantageous for the base plate modules to have a plurality of air feed openings and a plurality of air outlet openings, wherein air passages in each case protrude at the openings in such a way that, when two modules are plugged together, one protruding air channel engages in another opening. Here, a particularly secure attachment of the floor panels is achieved modular together by forming a plurality of connectors.

In particular, not all projecting air ducts are arranged exclusively at the air supply or exclusively at the air outlet openings, but mutually, so that a particularly secure attachment is ensured.

The projecting air ducts can also serve, except for the production of plug-in connections with further floor panel modules, to connect to one of the floor panel modules an air supply unit for supplying, in particular blowing, the air to be heated. In addition, other devices, for example an active oxygen generator, an ion generator or an energy-saving sensor can be connected via the air supply openings.

The air duct or the air ducts which are inserted into the corresponding other openings, in particular have a rectangular cross-section. This ensures that the openings are formed as large as possible and thus as much air can flow in and out. In an alternative embodiment, other cross sections, for example a square cross section, an oval cross section or a round cross section, can also be used.

The spacer plate, the bottom element and the four side elements and all other previously mentioned optional components are in particular firmly connected to each other at the factory, so that only a mating of the individual modules must be done on the site and a particularly quick and easy installation is achieved.

In addition, the transport and storage costs are reduced because as few individual items must be transported and stored.

Specifically, the bottom plate modules are formed such that the air space is sealed airtight except for the scheduled air supply openings and air outlet openings by the spacer plates, the bottom element and the side elements, so that no unintentional escape of air can take place.

The spacer plates and the bottom element are arranged in particular parallel to each other. It is also advantageous if the four side elements are each arranged orthogonal to the spacer plate and the bottom element and if two mutually adjacent side elements are each also orthogonal to each other. This results in particular a cuboid base plate module, which can be handled very easily.

In particular, the bottom plate module has a length of between 1,100 and 1,200 mm, preferably between 1,180 and 1,250 mm, a width between 1,110 and 1,300 mm, preferably between 1,180 and 1,250 mm, and / or a height between 30 and 60 mm, in particular between 45 and 50 mm. This ensures that the individual base plate modules can be handled easily manually and in particular no great physical effort is necessary for this.

In a particularly preferred embodiment, the base module has a dimension of 1,240 x 1,190 x 48 mm and the supplementary module has a dimension of 1,190 x 1,190 x 48 mm. The base module is in particular a little bit longer than the supplemental module formed because in addition to the spacer plate on its top also the air outlet must be provided for outflow of air to the room to be ventilated. Thus, the same spacer plates can be used in particular for both types of modules.

The spacer element is in particular made of a plastic film or a metal sheet.

The depressions, knobs and grooves of the spacer plate are formed in particular by deep drawing of the plastic film or the metal sheet. Thus, a particularly simple and stable production is achieved.

Alternatively, the spacer plate may also be formed from minerals.

Furthermore, it is advantageous if the depressions are arranged equidistantly in rows and columns and if the channels extend transversely in columns and lines. Thus, the corresponding tubes can be installed at regular intervals and in different directions.

It is particularly advantageous if grooves are provided, which extend diagonally to the column and line by line grooves.

Moreover, it is advantageous if between each four frustoconical depressions, a circular groove is formed, which coincides at least partially between each two wells with in the column and line-wise grooves.

A further aspect of the invention relates to a cavity floor which comprises an underbody, at least one bottom plate module resting on the underbody according to the previously described type, tubes applied to the bottom plate module and a topsoil applied to the bottom plate module.

In particular, the cavity floor comprises, depending on the performance, one or more base plate modules, which are connected to one another by corresponding plug connectors.

The subfloor is designed in particular as a continuous impact sound insulation the floor panels can be easily laid.

The air-carrying channels of the bottom plate modules are sealed in particular on the upper side with self-adhesive foam tape against screed moisture and sound bridges. In particular, 3 mm wide PE foam tape is used.

The pipes carrying the heating and / or cooling medium are in particular cast in a screed which encloses the pipes at the locations which do not rest on the spacer plate and also fills the spacer elements, thus giving the necessary stability and compressing the spacer plate is avoided.

Further features and advantages of the invention will become apparent from the following description, which illustrates the invention with reference to embodiments in conjunction with the accompanying figures.

In 1 is a schematic perspective view of a base module designed as a base plate module.

The basic module 10 includes a spacer plate 14 , one in 1 invisible floor element 16 as well as four page elements 18 to 24 , About the floor element 16 , the distance plate 24 as well as the four side elements 18 to 24 is an airspace 26 limited, is passed through the air. The basic module 10 is used in particular in the context of controlled living and room ventilation in residential and commercial premises and serves to ventilate the rooms, to heat and / or to cool. For this purpose, through the cavity floor, through the base module 10 and supplementary modules if necessary 12 can be formed, passed through an air flow, which is heated or cooled via a heating or cooling medium leading in the floor laid pipes.

The spacer plate 14 is in particular designed such that it on its underside, ie the side which in 1 is not visible and to the floor element 16 is turned, has a plurality of frustoconical depressions are formed by the bumps and which are formed in particular by deep drawing the spacer plate in this and on the spacer plate 14 on the floor element 16 gets up. The air flows around these depressions, leaving the spacer plate 14 according to heat or cold can be discharged to the air flowing around.

On its upper side, the spacer plate 14 a plurality of cams, one of which is exemplified by the reference numeral 28 is designated. Between the cams 28 is formed a plurality of line-shaped grooves, in which, as in 1 only indicated by way of example, heating pipes 32 can be inserted. Through these cams 28 on the one hand a simple positioning of the heating pipes 32 and on the other hand a particularly high and efficient heat transfer from the heating pipes 32 to the spacer plate 14 and from this on to the base module 10 reached by flowing air. Here are the gutters 30 in particular designed such that the spacer plate 14 the pipes 32 significantly more than half encloses, so that a particularly good heat transfer or cold transfer is possible and the spacer plate 14 as an efficient heat exchanger between the heating and cooling of the pipes 32 and the airspace 26 flowing air is used.

The first page element 18 has three air intake openings 34 to 38 on, in particular, have a rectangular cross section and are formed in particular the same size. Through these air supply openings 34 to 38 the air gets into the airspace 26 introduced before then flows through this.

At the first side element 18 opposite side of the base module 10 is an upward-pointing air outlet 40 provided, over the air, as by the arrows 42 shown after it has been heated or cooled, is delivered to the room to be ventilated. This air outlet 40 is in 1 shown in exploded view to the individual components 44 to 48 to make visible.

The air outlet 40 includes a grid installation box 44 , a screed block 46 as well as a grid 48 , The screed block 46 encloses the lattice installation box 44 and thus gives it stability. The grid 48 is in the lattice installation box 44 inserted and closes the opening upwards.

The outlet opening 40 extends in particular almost over the entire width of the base module 10 , so that the ventilation takes place in the form of a source ventilation and thus as possible no drafts occur. In particular, the air is only 0.2 m / s from the outlet opening 40 executed.

At the middle of the feed opening 36 is an air duct 50 provided, which as a connector for connecting the base module 10 with further bottom plate modules, in particular with so-called supplementary modules 12 , serves.

In 2 is such a supplementary module 12 shown, which also has a spacer plate 14 , a floor plate 16 and four page elements 18 to 24 having. The spacer plate 14 of the base module 10 and the supplementary module 12 is particularly identical, so that only one type of spacer plates 14 must be used. The basic module is corresponding 10 trained a little longer, because this, unlike the supplementary module 12 , the upward-pointing air outlet 40 having.

The supplementary module 12 has in place of the directed to the room to be ventilated air outlet 40 at the first side element 18 opposite third side element 22 three air vents. The air outlet openings are in particular the same size as the three air supply openings 34 to 38 formed, so that by plugging together a base module 10 with a supplementary module 12 like this in 3 shown is the modules 10 . 12 can be easily connected with each other. Accordingly, of course, two supplementary modules 12 be put together.

The supplementary module 12 has for mating in particular at the two outer air outlet openings in each case an air duct 52 . 54 on which into the air supply openings accordingly 34 . 38 of the base module 10 or the other supplementary module 12 can be inserted. Thus, in particular between two modules 10 . 12 in each case one plug connection via three plug connectors, namely the three projecting air ducts 50 to 54 ,

In an alternative embodiment of the invention, some air channels can not 50 to 54 at the air outlet openings and others at the air supply openings 34 to 38 but all air channels 50 to 54 at the air supply openings 34 to 38 or all air channels 50 to 54 be provided at the air outlet openings.

In a further alternative embodiment, it is also possible that more or less than three air supply openings 34 to 38 and air outlet openings are provided.

To the air supply openings 34 to 38 can be an alternative to other supplementary modules 12 a ventilation device are connected, which controls the air flow. In particular, adapters can also be provided, via which the shape of the air inlet openings 34 to 38 or the air duct arranged on them 50 can be adapted to the shape of the air outlet openings and / or air ducts of the ventilation device. In particular, adapters may be provided for connecting oval or round air ducts.

In addition to the ventilation device, for example, an active oxygen generator for eliminating hygienic loads and indoor air quality improvement, an ion generator and / or energy saving sensor can be connected to ensure the hygiene of the entire ventilation system and the room air and in particular the indoor air quality as far as with natural oxygen corresponding to the outside air and better to enrich that this corresponds to a healthy indoor air.

The use of such oxygen activators also has the advantage that mechanical cleaning can be omitted, since channels and air outlets are cleaned independently and permanently.

To build the cavity floor, the modules 10 . 12 simply placed on a subfloor, which may be in particular an impact sound insulation or thermal insulation. The number of modules used 10 . 12 depends in particular on the size of the room and / or the heating, cooling and / or ventilation performance to be achieved. This principle is intended by the 4 to 6 be clarified.

In 4 is the minimum possible system, namely only one basic module 10 provided the air as indicated by the arrow 60 indicated, is supplied directly from the ventilation unit and on the air after flowing through his airspace 26 according to the arrow 62 is delivered to the room.

At the in 5 shown system is next to the base module 10 a supplementary module 12 to the base module 10 infected, so that the air can be warmed up and / or cooled accordingly. The dashed lines indicate that there is also another supplementary module 12 Optionally can be connected, reducing the airspace 26 is further increased and thus still one stronger and more efficient heating or cooling effect is achieved.

At the in 6 shown embodiment, three base modules are arranged side by side, which are not connected to each other, ie that there is no connection between their air spaces. To each of these base modules 10 are two supplementary modules 12 connected. Thus, a particularly high air outlet volume is achieved by this system, whereby on the one hand a higher ventilation performance and on the other hand a strong heating or cooling effect is generated.

After the modules 10 . 12 The joints between them were sealed with the help of a sealing tape, in particular with the aid of self-adhesive PE foam tape.

Further, in the grooves 30 the modules 10 . 12 the pipes 32 placed through which the heating or cooling medium is passed.

Subsequently, on the modules 10 . 12 Screed poured or mineral-compacted thermally conductive filling applied by the or the pipes 32 are embedded and by the or the spacer elements, in particular the conical depressions of the spacer plate 14 be filled and thus give it stability. In the case of mineral fill, in particular, for example, a mineral load distribution plate is applied on the upper side.

On the screed is then applied after it has cured, the actual flooring.

Through the bottom plate modules described above 10 . 12 is achieved a number of advantages compared to conventional systems in which the individual components are all mounted individually.

On the one hand it is achieved that the cavity floor can be planned and installed quickly and safely by untrained personnel in a simple manner. In particular, no special expertise is necessary for this.

In addition, only a small storage capacity and storage is needed because only two different items, namely the base modules 10 and the supplementary modules 12 instead of having to stock more than ten individual items so far.

The modules 10 . 12 All are already factory-mounted so that the assembly and installation effort on the construction site is minimized.

In addition, these prefabricated modules have 10 . 12 the advantage that they form a closed unit and thus contamination during assembly, in particular deposits within the airspace 26 be avoided.

In particular, the assembly effort can be reduced by 80%, so that only 20% of the time is needed, which was necessary for the construction of individual elements.

The modules 10 . 12 in particular just have a height of 48 mm, so that a particularly compact design is achieved. In particular, the side elements have 18 to 24 a height of 30 mm and the cams 28 a height of 18 mm.

Through the plug connection a simple, yet secure installation is achieved.

The modules described above 10 . 12 can also be used not only as floor modules, but also as Wandheiz- or wall cooling surfaces.

In particular, the air connection channels have a dimension of 150 × 30 mm.
