In 1 is a schematic cross section through an outer wall according to the invention shown. The outer wall consists of an outer wall 1 and an inner wall 2 from hollow blocks 3 . 4 passing through a cavity 5 are separated from each other. In the cavity 5 is a thermal barrier coating 6 brought in. Between the inner wall 2 and the thermal barrier coating 6 is a metal grid 7 , esp. A steel grid, arranged, to which by means of electrical heating conductors 8th Heat energy is transferable. The walls 1 . 2 , the metal grid 7 and the heating conductor 8th are connected to each other by foaming with thermal insulation foam, in this foaming and the thermal barrier coating 6 is formed in the same way. As thermal insulation foam may preferably serve PE foam, which also has a good adhesive property. The two walls 1 . 2 can also be additionally anchored to each other, for example by means of anchor plugs or metal claws.

The metal grid can after 2 from vertical solid rods, such as the rods 9 , and horizontal rods, such as the rods 10 , which are interconnected at the intersections, for example by soldering or welding. The heating conductor 8th is in loops on the metal grid 7 applied and, as from the enlarged cross section in 3 recognizable, on some horizontal solid rods 10 by means of wire loops 11 attached. This wire loop attachment does not need to be particularly strong because metal mesh 7 and heating conductor 8th be foamed. The heating conductor 8th is supplied via the terminals plus and minus of a power source power, which can be controlled in a known manner by means of a thermostat. Preferably, the power source may consist in a photovoltaic system.

Of course If necessary, the heating element can also be used on some vertical solid rods be misplaced. It is also possible to place the heating conductor between the vertical bars or between the horizontal bars to lay parallel to these. The laying of the heating conductor must in addition to the windows and doors in a building judge.

In 4 is the outer wall 1 a building shown on the building floor 12 stands. At some distance from this outer wall is the metal grid 7 , which rests against the inner wall, not shown.

Metal mesh and heating conductors can also be connected to each other in other ways. Thus, the metal grid can consist of vertical tubes and horizontal tubes. In at least some such tubes, the heating conductor may be arranged. So is in 5 a cross section through such a tube 13 shown. In this tube closes inside a reinforcing cover 14 , especially of ceramic, to which again the original cover 15 made of ceramic of the heating conductor 8th which surrounds this one. The heat transfer from the heating conductor 8th on the pipe 13 is especially good, the heating conductor 8th is protected in the pipe 13 , and the risk of fire is reduced.

The outer wall 1 and the inner wall 2 can in principle consist of any hollow blocks. Advantageously, however, a block-shaped hollow block with at least one chamber can be used, which has a heat insulating layer facing, large-area opening in the chamber wall, said chamber is filled with the cavity between the outer wall and inner wall simultaneously. The bracing of these walls will be even better if after 6 a hollow block 3.1 with two chambers 16 . 17 with one opening each 18 . 19 is used. The hollow block 3.1 is also on its top 20 , Bottom 21 and the side surfaces 22 . 23 with grooves, like the grooves 24 . 25 provided, wherein in these grooves adjacent hollow blocks can be fitted with corresponding grooves. On the top 20 , Bottom 21 and the side surfaces 22 . 23 are also holes, such as the holes 26 . 27 , provided in the chambers 16 . 17 to lead. Through these holes, the thermal insulation foam for clamping the hollow blocks occurs.

A further, improved embodiment of a hollow block used in the invention 3.2 is in 7 shown. The hollow block 3.2 is again basically cuboid with two chambers 16 . 17 with one of the thermal barrier coating facing, large-scale opening 18 . 19 educated. The chambers 16 . 17 lie in Steinlängsrichtung one behind the other and are separated by an intermediate wall. On top of the hollow block 3.2 is a central longitudinal rib vorgese hen on the left side in a central end rib 29 passes. On its underside is a central longitudinal groove 30 and on its right side is a central brow groove 31 provided, which also merge into each other. In the longitudinal rib 28 , the forehead rib 29 , the longitudinal groove 30 , the forehead groove 31 , and the intermediate wall of the hollow block 3.2 are holes, like the holes 26 . 27 . 32 . 33 . 34 , arranged by the thermal insulation foam from the chambers 16 . 17 can penetrate into adjacent hollow blocks.

Ribs 28 . 29 can contact the grooves ( 30 . 31 ) be adapted adjacent hollow blocks. It is useful, after 8th the tops of the hollow blocks 3.2 and the bottoms 36 with transverse grooves 37 provided to impede the slipping of the hollow blocks.

A better way to obstruct the slippage of the hollow blocks in the composite, however, is achieved in that the height and width of the ribs 28 . 29 less than the height and width of the grooves 30 . 31 are measured. Between such ribs and grooves can now enter the thermal insulation foam.

In 10 is an outer wall 1 shown from such hollow blocks 3.1 or 3.2 is constructed and on the edge of a building floor 12 stands. The building floor 12 is near his edge 38 running holes 39 provided, in which the thermal insulation foam from the hollow blocks can enter.

In 11 is an external masonry made of hollow blocks 3.1 or 3.2 a building with a number of rooms shown. The front of this outer masonry spaced metal grille 7 is divided into the rooms assigned parts. So is a first nursery 40 a metal mesh part 7.1 one bedroom 41 a metal mesh part 7.2 , a bath 42 a metal mesh part 7.3 , a toilet 43 a metal mesh part 7.4 , a hallway 44 and a living room 45 a metal mesh part 7.5 , a kitchen 46 a metal mesh part 7.6 and a second nursery 47 a metal mesh part 7.7 assigned. The vertical bars 9 ' and 9 '' the metal lattice parts 7.1 and 7.7 can be strengthened and are by parentheses 48 made of plastic and at the same time thermally separated. The 12 shows this in an enlargement. There is also underfloor heating 49 indicated, which can be mitgesteuert with advantage. Claws can be used instead of brackets.

The single, the metal grid parts 7.1 - 7.7 associated Heizleiterteile are also separated, and the thermal energy supplied to them is separately adjustable.

If, for various reasons, an increased heat demand is required, additional heating may be provided in the relevant room on an external wall 50 be attached in the form of a flat body. This can be arranged in the usual way under a window, but also at the level of an image. The flat body may be covered, in the latter case preferably by means of an image.

The 13 - 15 show an example of such additional heating 50 , Between two rectangular metal plates 51 . 52 is a zigzag heating conductor 53 locked in. From the inner plate 52 flush with the inner wall 2 shut down metal bars, like the bars go 54 , which are connected to the metal grid, not shown, for example, welded, are. The heat of the metal grid goes to the plates 51 . 52 over, and at the same time can the heating conductor 53 separate power via pins 55 . 56 be supplied.
