The invention is therefore based on the object of an outer wall construction to provide from easily prefabricated and easily transportable to the construction site components that are easy and have it built quickly. By using prefabricated Lightweight panels are aimed at, an excellent seal of the wall, a high thermal insulation and good To achieve sound absorption properties as well as high resistance to all atmospheric conditions.

To solve the problem underlying the invention, the invention is by on a load-bearing frame of the Building attached support arms on which the panels are side by side are placed with the interposition of two right-angled angle profiles, the protruding legs of which face each other are and engage in a groove in the lower edge of the board, and characterized in that the vertical longitudinal edges of adjacent boards are also provided with a groove each, the pairs form a channel that is potted by a binder. In the construction according to the invention are therefore to connect the lined up panels used three types of support arms; In addition, the panels are attached to one another by means of glue or the like. tied together.

More specifically, the procedure is such that _s the panels are erected vertically and fixed to the rectangular support alarm seed, of which one side by elements of the load bearing framework of the building is welded.

The prefabricated panels used for the purposes of the invention Use are preferably cement boards, which are made essentially of cement mortar and expanded synthetic material by extrusion and rework.

In this way one can obtain components of large dimensions with low tolerances, with the manufacturing tolerances in any case can be of the order of one millimeter.

Expanded phenolic resins, urea resins or polyurethane resins, or even more, are used in the manufacture of such panels better expanded polystyrene, which is a lightweight product without any disadvantageous properties in terms of its required, very result in high mechanical strength properties.

For the purpose of the invention, lightweight panels are used which are manufactured so that they are symmetrical along the corresponding two Outer edges each have a groove, so that these two grooves in adjacent panels are a composite of both grooves Resulting cavity, which is filled with a binding agent and thus a high transverse strength and perfect insulation results.

In a modification of this vertical connection of neighboring You can also board a guide tube in the two grooves

Pig. Figure 7 is an isometric view of an exterior wall construction in accordance with the invention.

From Fig. 1 it can be seen that in the construction of the outer wall structure Using lightweight panels on the longitudinal edges each has a groove 2 that is symmetrical to the two Outer edges of the rim is arranged and preferably, as shown, has a rounded cross-section, while however other cross-sectional shapes can also be used.

The adjacent panels can be connected to each other by making the grooves formed by the two facing each other Pour the channel with a binding agent 3, as can be seen from FIG. Preferably, the edges of adjacent panels abut 6 to one another, even if they can also show some distance according to FIG. 4, since the pouring strand 3 of the binder results in a complete seal.

From Fig. 3 it can also be seen that the table in each case together their vertical binder strand 3 on two right-angled angle profiles sits, one leg of which runs horizontally parallel to the underside of the panel 1 and the other two legs are facing each other and together in a groove 8 on the lower Engage the edge of panel 1. This creates an overlapping seal here.

In detail, the angle profile 4 is made of metal, while the angle profile 5 is made of plastic and one down Has protruding leg from which another horizontal leg protrudes and a compartment or housing for a Stüijzarm 7 (Fig. 2) forms. As can be seen in Fig. 2, the support arm Io is also a right-angled profile piece on which the two Profile pieces 4 and 5 rest and with one on the inside of the building vertically extending leg is attached to a load-bearing element 11, for example a support beam of a ceiling or a floor of the building. It goes without saying that with this Construction, the panels 1 are designed floor-high.

As can also be seen from FIGS. 2 and 7, the protrudes below the web of the angle profile 4 even further than that for the recording of the support arm Io serving compartment 6 down and forms one Angular space 7 »as a housing for the outer upper edge of the immediate serving below the panel 1 and is connected to it by an adhesive or other binding agent. That Metal profile 4 can with the underlying panel 1 in the usual Way be connected by screwing.

Both profiles are, as already mentioned, right-angled in cross-section, with the shorter arm in the groove 8 in the lower edge the panel 1 engages.

The plastic angle profiles 5 can be made of synthetic resin, such as polyvinyl chloride, which as rigid cross-sectional shape is extruded.

The binders poured into the voids between the panels can either cement mortar or gypsum-like material or organic polymeric adhesives, for example based on Vinyl resins, urea resins, acrylic resins or epoxy resins, which are normally used as binders for such purposes.

The same binders are also used to fill the angular space 7 between the outer angle profile 5 and the outer edge the table below it 1 use.

In this way a perfect seal is obtained between the panels, both vertically and horizontally; this is illustrated in particular in FIG. 3, where one can see that, for example, raindrops cannot find their way into the interior of the building.

From the horizontal sectional view of FIG. 4 recognizes first the connection of adjacent panels 1 by means of a binding agent strand 3. One arm of the support arm Io is welded to the profile section 11 of the load-bearing structure of the building. The points at which the metal profiles M (Fig. 2 and 3)

are attached to the panels below are marked with 12 designated.

In the variant essentially corresponding to FIG. 2 Fig. 5 is particularly remarkable the shape of the angle profile 5, which also has one facing up on the outside of the panels has pointing web, which delimits an angular space 13 which surrounds the outer lower edge of the panel 1 adjoining above and is also filled in by the binder. The remaining reference symbols correspond to those of FIG. 2.

In Fig. 6 it can be seen how between adjacent panels, a tube 14 in the two mutually facing grooves of the panels within of the binding agent strand 3 is embedded. Flattened areas used for alignment can be seen at 15, the binder 3 is inserted between the tube and the outer surface of the facing grooves of the panels.

From Fig. 7 one can see the floor-high formation of the panels and the way they are supported by the support arms Io are, which in turn are welded to the profile parts 11, which are part of the supporting structure of the structure.
