Description

Prefabricated solid house in modular construction

The present invention relates to a prefabricated solid house in modular construction according to the preamble of claim 1, a method for assembling a prefabricated solid house in modular construction and a wall element, in particular for prefabricated solid houses in modular construction, according to the preamble of claim 14.

In known prefabricated houses, which consist of numerous individual elements, assembly is usually started from the upper edge of the basement or the upper edge of the foundation. In the case of a solid prefabricated house, the gable walls and side walls are then placed, on which corresponding ceiling elements are placed. The concrete side walls represent the load-bearing elements which are arranged inside after the house has been completed.

In order to meet the requirements of adequate heat and sound insulation, the load-bearing solid gable walls and the side walls are clad on the outside of the house by means of a corresponding layer system, which has to fulfill several functions. As a rule, an appropriate insulating layer made of suitable heat and sound insulating materials is attached to the load-bearing concrete wall. Before leaving a corresponding air circulation gap, which also has thermal insulation properties, a cladding is bricked or otherwise erected, which on their outside, ie the outside of the house, often receives a corresponding protective and / or beauty veneer, for example in the form of clinker panels. Although this basic structure and the basic _method for building such wall systems of a solid house meet the requirements resulting from thermal and sound engineering aspects, they are costly and material intensive on the one hand, but on the other hand they also have a relatively large thickness, which, based on reduced to the outer dimensions of the completed house, the usable enclosed space.

In order to further reduce the assembly effort in such prefabricated houses, as well as from other, in some cases also ecological, aspects, prefabricated houses are often made of wood, based on the material used to the greatest extent. The gable and side wall panels used in a timber construction of a prefabricated house are manufactured as sandwich panels and have a corresponding inner cladding, an insulating material and an outer cladding, with support posts between the inner cladding and the outer cladding in the area of the insulating material are used. When using wooden support posts of this type, the region of the side walls or the gable walls between the support posts is therefore non-load-bearing.

A disadvantage of such a construction is that the forces introduced into the foundation are introduced essentially in a punctiform manner or into a relatively small area. Of course, the prefabricated wood parts with regard to insulation and sound insulation meet the required standards and can be completely prefabricated, but on the one hand a prefabricated wood house also requires a concrete foundation, which in part saves the savings when building a prefabricated wood house compensated because time-consuming formwork and concrete casting processes precede the assembly, on the other hand the load-bearing capacity of such wooden wall elements is limited.

It is therefore the object of the present invention to provide a prefabricated solid house in modular construction which on the one hand combines the advantages of a prefabricated wood house with those of a prefabricated concrete house and on the other hand can be assembled as completely as possible at the installation site without time-consuming concrete casting work.

Another object of the present invention is to provide a method for erecting such a prefabricated solid house in modular construction, with which a reduced assembly effort with improved sound insulation, reduced wall thickness and high load-bearing capacity can be achieved.

Furthermore, the object of the present invention is to provide a wall element for a prefabricated solid house in modular construction, which can be completely assembled and by means of which mortar residues and the like fall between the insulation layer and the outer cladding and thereby negatively affect the required air circulation becomes.

These tasks are solved by a prefabricated solid house with the features according to claim 1, for the method for erecting such a prefabricated solid house by a method with the features according to claim 11 and for a wall element with the features according to claim 14. Appropriate further developments for the prefabricated solid house, the method for erecting such a prefabricated solid house and for the wall element, in particular for a prefabricated solid house, are defined in the corresponding subclaims.

According to the invention, the prefabricated solid house in modular construction has a foundation, outer wall elements in the form of gable wall and side wall elements, staircase elements, ceiling elements and insulating elements. In particular, the outer wall elements are designed as multi-layer sandwich panels which, in terms of their basic structure, have a supporting wall and further functional layers that perform certain functions. According to the invention, the supporting wall of the outer wall elements is an external, load-bearing concrete slab on which the functional layers are attached on the inside. The functional layers fulfill heat, sound and moisture damping or barrier properties according to a corresponding structure. "Outside" refers to the outside surface of the house facing the surroundings, and "inside" refers to wall surfaces directed into the respective rooms of the house.

In order to be able to carry out only assembly work at the installation site of the solid house, but no actual manufacturing work, in one embodiment of the invention the solid house also has foundation elements which replace the foundations which have previously been cast. At the installation site of the house, all that needs to be done is to level the floor area accordingly, on which the foundation elements are placed according to the shape and size of the house and placed in a level arrangement. The basic problem with modular houses is that the house can be assembled as quickly as possible so that the house can be provided with a roof, so that the further expansion can be carried out regardless of the weather and in the case of unfavorable weather conditions, no negative influence from high humidity occurs on the components used. In this regard, the prefabricated solid house in modular construction according to the invention represents a house to be completely assembled on the construction site.

In a further preferred embodiment, the foundation elements are wider on their side facing the floor than on their side facing the outer wall elements, so that a correspondingly uniform power dissipation via the foundations is made possible and that the necessary leveling of the leveled foundation elements is achieved. The cross-section of the foundation elements is therefore preferably essentially trapezoidal. Concrete is saved due to the oblique force dissipation in the foundations. Because in comparison to known foundations with essentially parallel side walls, the areas are omitted in the foundation elements according to the invention, which do not contribute to the force dissipation or only to a small extent. Preferably, the angle of at least one side surface which connects the bottom side of the foundation elements with the side facing the wall elements is essentially 60 °.

The foundation elements have an upturn on their wall element side to support the outer wall elements and a recess for receiving ceiling elements. The thickness of the ceiling elements is designed so that after placing the same on the recess on the wall element side, the top of the ceiling elements the upper edge of the upstand is aligned so that a wall element to be arranged above it can be immediately set up precisely, without the space between the upstand side surface and the side surface of the ceiling elements, which is preferably poured with concrete or mortar, unaffected by an immediately installed load can harden. This can also shorten the assembly time for the entire house.

In another exemplary embodiment of the invention, the function layers arranged on the inside comprise at least one air circulation gap, an insulation layer and an expansion panel. The air circulation in the air circulation gap between the supporting concrete slab and the interior insulation layer is achieved by attaching a slatted frame to the inside of the supporting concrete slab, to which a heat and sound insulation layer can be attached. In the sense of good optics, a known expansion plate is attached to the immediate inside. The expansion board can be a known plasterboard, a wooden panel or the like. his.

In a further exemplary embodiment of the invention, a layer which is permeable to vapor diffusion is provided between the insulating layer and the air circulation gap and a moisture barrier layer is applied between the insulating layer and the expansion panel. Depending on the need and purpose, additional functional layers can be provided. The order of the functional layers can also vary from the inside to the outside depending on the application and requirements.

In yet another embodiment of the invention, a staircase element foundation is incorporated within the foundation elements, which is preferably also made in one piece from concrete and in Cross-section matches the cross-section of stairwell elements arranged above it. In the case of larger house units, a plurality of staircase elements can also be provided, in which case a corresponding number of staircase element foundations are then arranged at the desired locations in or between the foundation elements.

The stairwell element and the stairwell element foundation preferably have an inner wall and an outer wall, between which the stair is at least partially guided with a stair running line which is at the same distance from both the inner wall and the outer wall. On the staircase elements and the staircase element foundation, a shaft is also provided on the outer wall area, in which supply lines can be routed. The staircase elements can thus be completely provided with appropriate four-supply lines, which means that the space that can be used in the house can also be enlarged. On the wall areas facing the inside of the house, cantilever projections can be provided for receiving ceiling elements.

In the case of terraced houses, interior gables are also required, which are lined as load-bearing wall elements without having corresponding functional layers. However, it is also possible for certain functional layers to be provided. These inner gables rest on paired foundation elements, which are arranged in such a way that an insulating or insulating layer between the inner gables is guided downwards between the foundation elements. This has the main advantage that, above all, the transmission of structure-borne noise via the foundation from a house to a house next to it is largely avoided. This contrasts another advantage of the foundation elements - H -

a cast foundation, in which such insulation is not readily provided.

In order to ensure continuous insulation between wall elements and ceiling elements in a further exemplary embodiment of the invention, a layer ensuring reliable load-bearing capacity and insulation is arranged in particular between the ceiling elements of an upper ceiling or an upper floor and the load-bearing concrete slabs. The insulation refers to thermal insulation as well as sound insulation.

The method according to the invention for assembling such a prefabricated solid house preferably has the following steps. First, the foundation elements and at least one staircase element foundation are evenly arranged or leveled on a prepared floor area, which was previously leveled as precisely as possible. In order to achieve a uniform surface pressure and to be able to arrange the foundation elements or the staircase element foundation equally, a layer of a compressible material such as e.g. Sand or gravel as well as a thin layer of mortar or a layer of e.g. Dry concrete can be provided under the foundation elements.

After the staircase element foundation has been incorporated or arranged in the foundation elements of the solid house, a number of staircase elements corresponding to the desired number of storeys is first placed on the staircase element foundation. The advantage of such a staircase element is, inter alia, that no additional stairs are required for the inspection of already installed or just installed upper floors, but that Stairs themselves can already be used. The ceiling elements are placed on the foundation elements on the foundation elements or adjacent to the staircase elements and cast with the foundation elements. Then the gable wall and side wall elements are set up, namely the outer walls and the inner gable. This is followed by laying down ceiling elements again, but these are placed on the load-bearing concrete slabs of the entire gable wall and side wall elements. Finally, the gable wall and the side wall elements are connected to each other in a sound-insulated and heat-insulated, interior wall-free, as well as tensile and pressure-proof manner. This inventive sequence of assembling a prefabricated solid house, which, including the foundation, is completely ready for installation, means that the house can be provided with a roof in a considerably shorter time than with conventional prefabricated houses in solid construction, and thus achieve the desired rapid weather independence for subsequent finishing works become.

In order to further increase the assembly speed, it is provided in a further exemplary embodiment of the invention that the ceiling elements placed on the foundation elements are poured with concrete or mortar or another pourable and bindable material between an upturn on the top of the foundation elements and are thus fixed that the gable wall and side wall elements can be placed on the foundation elements immediately after casting. The thickness of the ceiling elements is designed so that it is aligned with the top of the upstand after being placed on it, so that gable wall and side wall elements resting on the upstand and on the top of the ceiling elements are fixed in position and the casting compound between the upstand and the end face of the ceiling can cure elements unaffected. This results in Monta _¬ ge of the individual elements no delays, and it is still a safe den¬ composite of the individual elements making each other gewähr¬.

According to the invention, a wall element is also created which can be used in particular for a prefabricated solid house, as described above. However, such a wall element can also be used without problems in other modular structures. Other possible uses are e.g. Garages or industrial buildings or similar The wall elements for the prefabricated solid house are of sandwich construction and have an outer veneer, a load-bearing concrete slab, functional layers and an inner covering in a manner known per se.

According to the invention, the load-bearing concrete slab of the wall elements is arranged on the outside and the respective functional layers are fastened to the inside of the concrete slab. For aesthetic reasons and for functional reasons, for example to repel weather-related moisture, the load-bearing concrete slab has a layer which is preferably designed as a clinker brick layer. This clinker brick layer is poured firmly in one operation with the actual concrete body, so that on the one hand the outside of the wall element is ready for final assembly and on the other hand time-consuming grouting work is also eliminated. The clinker brick slips are attached in such a way that they are partially deposited in a shape with correspondingly large recesses and the concrete of the load-bearing concrete wall is poured thereon, so that the clinker brick elements form a firm bond with the load-bearing concrete wall. The corresponding functional layers are then attached to the inside of the load-bearing concrete wall in specially provided devices, so that the outer wall elements can be delivered completely to the assembly point. The functional layers include, in the order listed, a circulation gap, an insulation layer and a expansion panel and preferably have a vapor diffusion-permeable layer between the circulation gap and the insulation layer and a moisture barrier layer between the insulation layer and the expansion panel. The extension panel can have a wide variety of designs for aesthetic reasons.

According to a further exemplary embodiment of the invention with respect to the wall element, the vapor diffusion-permeable layer on the side of the air circulation gap and the moisture barrier layer are attached to the insulation layer on the side of the expansion panel by adhesive bonding in a manner known per se.

Further advantages, features and possible uses of the present invention will now be explained in detail with reference to the drawings in the following description. The drawings show:

Fig. 9 is a sectional view of a stairwell element with shafts for supply lines.

1 shows a basic sectional side view of a prefabricated solid house in modular construction according to the invention. The foundation of the solid house according to the invention consists of foundation elements 4 and a staircase element foundation 6, which are aligned on a previously leveled piece of floor, the actual assembly point for the house to be erected, so that the corresponding modular elements are placed on it and can be attached. The foundation elements 4 are designed such that they have outer wall elements 1, which act as gable wall elements or can be designed as side wall elements and which consist of a i-supporting concrete wall 2 and several attached to it inside

Functional layers 3 are formed, and accommodate ceiling elements 5.

In the foundation ring formed from the foundation elements 4, a one-piece cast staircase element foundation 6 is integrated. Like the foundation element 4, the stairwell element foundation 6 has a projection or a recess for receiving ceiling elements 5. This creates a crawl space. The stairwell element foundation 6 has a number of stairs corresponding to its height. In cross section, the one-piece staircase element foundation 6 is designed such that the actual staircase elements 30 can be placed on the staircase element foundation 6 with identical cross-sections. Since the staircase elements are also designed as modular elements and have cantilevered projections, no further internal wall bracing is required to accommodate the ceiling elements 5. These ceiling elements 5 are fastened directly to the corresponding cantilever projections of the stairwell element 30.

The representation according to FIG. 1 corresponds to a house in a row construction, to which a further house in an analog, modular construction can be connected to an inner gable 7. The elements of the upper floor are then designed in a manner known per se in accordance with the respective module spacing and placed on the lower floor and connected to it in a corresponding manner, as will be explained in more detail below.

2 shows an outer wall element in the form of a gable wall element. The outer wall element 1 has a total wall thickness of approximately 34 cm. The outer wall element 1 has an outer one load-bearing concrete slab 2, to which a corresponding protective cladding in the form of clinker straps 8 are firmly cast on to the outer facade of the house. Spacer timbers 14 are bolted to the concrete wall 2 at a distance corresponding to the module spacing on the inside of the load-bearing concrete wall 2 by means of bolts. These spacer timbers 14 serve to receive the further functional layers of the outer wall element 1 on the inside of the concrete slab 2. Between the further functional elements 10, 11, 12, 13, an air gap or an air circulation layer 9 is formed by the spacer timbers 14, which or which is necessary for air circulation and prevents condensation from being absorbed by the insulating and insulating material. The spacer timbers 14 are fastened to the concrete slab 2 in a manner known per se by means of a dowel connection. The functional layers consist of a vapor diffusion-permeable layer 10 in the form of a film, an insulating or insulating layer 11 adjoining it on the inside, a moisture barrier layer 12 attached to it and attached thereto, and an outer layer building board 13, which represents the actual inside, which faces the room inside the house. This basic layer-like structure represents a sandwich construction, which has additional elements and recesses at joints, so that the corresponding adjoining elements such as outer wall gable elements or inner wall elements can be connected to each other in a pull and pressure-proof, heat and sound-insulating and load-bearing manner. Rod connecting elements 15 serve as connecting elements for a straight joint of two adjacent outer wall elements in the form of a gable element.

FIG. 3 shows an example of a corner connection between an outer wall in the form of a gable wall element and an outer wall element in FIG Shape of a side wall element. The basic structure of the wall element according to the invention corresponds to that described in FIG. 2, with the difference that the side wall element has a total thickness of approximately 27 cm. The corner connection between the gable wall element and the side wall element is made by suitable bracket connecting elements 16 and rod connecting elements 15 in the area of the load-bearing concrete slabs 2. Wooden elements are integrated within the functional layers 10, 11, 12, 13, the spacing of which is the module spacing of the spacer timbers 14 at the correspond to the load-bearing concrete wall 2 and can thus be fastened to the spacer timbers 14. The module spacing (a) is fixed for a specific house type, but can be adapted to the respective building types if the proportions differ. Furthermore, a window opening 17 is shown in FIG. 3. For reasons of moisture protection to repel weather-related moisture, the outer brick clinker 8 is led into the lintel.

FIG. 4 shows how an outer wall element 1 in the form of a gable wall element and a ceiling element 5 are arranged on a foundation element 4. The foundation element 4 has on its side facing the floor an enlarged floor area 18, which ensures that, on the one hand, the forces are uniformly introduced into the floor and, on the other hand, a reduced surface pressure occurs. For reasons of strength, the foundation elements 4 are reinforced with a reinforcement 28. On the side of the foundation element 4 facing the gable wall element, an upstand 19 is provided approximately in the middle of the upper side of the foundation element 4. In addition to this upstand 19, a recess 20 is provided which points into the interior of the house and is lowered into the foundation element 4 and serves to support the ceiling elements 5. On this recess 20 opposite side of the upstand 19 is also a Ausneh _¬ mung which serves to receive the load-bearing concrete slab 2 on the foundation element 4. The load-bearing concrete slab 2 is fixed to the foundation elements 4 by means of an anchoring bolt 23

5 connected. In order to ensure a corresponding air circulation between the air circulation layer 9 and the environment, an air gap 22 is provided at certain intervals in the longitudinal direction of the foundation element 4 between the recess for receiving the load-bearing concrete slab 2 and the load-bearing concrete slab. If the ceiling element io 5 is placed on the recess 20 after a relatively small amount of potting compound has been applied to the recess to compensate for unevenness, an intermediate space or a potting space 21 can be filled with a potting compound, which is concrete or mortar become. This potting compound is used to produce a bond between the ceiling elements 5 and the foundation elements 4. Since the thickness of the ceiling element 5 is selected such that after the same has been placed on the recess 20, the upper edge of the ceiling element 5 with the upper edge of the Upstand 19 is aligned, the gable wall element can be placed on the foundation element 4 immediately in the not yet hardened state of the casting compound 0, without assembly delays due to the casting compound being cured. The potting compound can also be introduced into the potting space 21 after the outer wall elements have been installed. Further insulation or insulation 24 5 is provided on the ceiling element 5 and is covered with a screed layer 25. Since the thickness of the gable wall element is greater than the thickness of the side wall element, the bottom surface 18 of the foundation element 4 is also made wider for receiving gable wall elements. 5 shows the same basic arrangement of an outer wall element 1 and a ceiling element 5 on a foundation element 4 corresponding to the structure according to FIG. 4. However, since it is a side wall element whose overall thickness is less than that of a gable wall element, the foundation element 4 is made smaller in terms of the size of the bottom surface 18. All other structural elements are similar to those shown in Fig. 4, with the exception that the ceiling element 5 is designed as a hollow ceiling element in a manner known per se. The potting in the potting space 21 ensures not only continuous insulation but also a complete seal between the inside and the outside of the house.

Fig. 6 shows an interior gable wall arrangement as used in row houses, i.e. of adjoining houses. The inner gables 7 are placed on foundation elements 4 placed against one another, an insulation layer / insulation layer 27 made of Styrodur or another suitable heat or insulation material being provided between the two foundation elements 4. The foundation elements 4 carrying such a pair of inner gables 7 in turn have the upstand 19 for supporting the inner gable 7 and the recess 20 for receiving the ceiling elements 5. A support surface 26 for receiving a load-bearing concrete outer wall is not necessary and is therefore not provided. The basic structure or the assembly sequence is analogous to that described in FIGS. 4, 5.

7 shows the connection of an inner gable 7 to a side wall element as a corner connection by means of a bracket connecting element 16. The bracket connecting element 16 is anchored in the load-bearing concrete slabs 2 analogously to the type shown in FIG. 3. FIG. 8 shows the insulating connection that realizes the load-bearing capacity between an outer wall element 1 according to the invention and a ceiling element 5 in the area of an upper floor. Such a layer 29, which ensures the load-bearing capacity and the insulation, on the one hand ensures complete sealing of the building from the outside in, but on the other hand creates a connection between the air circulation layer and the outside of the house by the arrangement of ventilation channels. On the outside of the house in the upper gable area, additional planking can be provided, for example as a drift wall, behind which an air circulation layer is also provided.

9 shows a basic cross-sectional view in the form of a plan view of a staircase element 30 according to the invention. The staircase element 30 has an inner wall 31 and an outer wall 32, between which the individual stair steps 35 are arranged. The stair running line 34 is parallel both to the inner wall 31 and to the outer wall 32. The inner wall 31 has a curved region and a straight region lying therebetween. The outer wall 32 likewise has curved regions with a correspondingly larger radius and a region lying parallel to the straight region of the inner wall 31. In addition, the staircase elements 30 have a receiving space for supply lines on each side of the staircase element 30. This recording room is of sufficient size to accommodate all essential supply lines so that important useful space inside the house is not lost.
