Description

The present invention relates to hybrid buildings that are ready for occupancy or can be set up immediately on site.

In addition, the present invention relates to the use of the hybrid building for the production of all types of buildings

State of the art

From the American patent application US 2001/0047628 A1 For example, transportable modular units made of steel and a method for assembling these units into structures on site are known in order to create buildings with living and working spaces that are non-flammable and resistant to unhealthy contamination as well as strong winds and other environmental conditions. Each module unit is essentially completely prefabricated and finished in order to enable immediate occupancy and predetermined use.

From the translation DE 603 14 454 T2 of the European patent specification 1 579 087 B1 a modular assembly with a skeleton shell is known, which is oriented so that it defines the walls of a room or rooms. The structural units form the interconnected rooms of a building when they are stacked in a vertical and horizontal row. It is essential that for the precise localization of a module or a part thereof vertically above another module, each module is provided on the circumference of its base with a mounting flange extending downwards. In addition, each module is also provided with an outer roof covering of load-bearing formwork, which is lined with an edge of cold-formed lightweight steel up to but not quite the outer periphery of the top of the module. The edge has a first portion that overlaps over the top of the side and end walls of the module and a second portion that overlaps over the outer edge of the formwork so that a surrounding set-up recess is formed between the first and second portions of the edges into which the installation flange of a vertically adjacent module can be precisely inserted.

From the German utility model DE 20 2017 107 660 U1 a building module with a cuboid housing which forms a floor, a ceiling, two side walls and two end walls is known, a door and a window being arranged in the housing. That The housing consists of a monolithic tubular body made of a concrete material. The four pipe walls form the floor, the ceiling and the side walls. The door and the window are arranged in the end walls. The concrete active ingredient contains pores as well as porous mineral material such as expanded clay or pumice stone distributed in the concrete active ingredient.

From the international patent application WO 2009/061702 A1 a modular building construction system is known which comprises a plurality of modular building construction units having a predetermined length, width and height which essentially correspond to those of standard shipping containers. The modular building construction units are configured in such a way that they can be placed on a foundation at specific distances from one another. They have exterior surfaces, some of which serve as molds for poured concrete. The building construction system also includes reinforcement between and above the modular building construction units. The concrete that is poured over the reinforcement means forms some exterior surfaces of the modular building construction units, with the concrete and reinforcement forming a monolithic reinforced support structure for the modular building construction system.

From the American patent application US 2012/2255710 a building system for housing electronic devices is known. The building system includes a building stack that includes a modular instrumentation assembly with an internal room configuration configured to house electronic devices, power distribution equipment, power filtering equipment, an uninterruptible power supply, a modular cooling unit that includes an air conditioner, and a water cooling unit.

From the American patents US 9,068,340 B2 and US 9,593,478 B2 methods and devices are known which facilitate the construction of a building using prefabricated structural units. The building units each include a horizontal upper outer surface and a plurality of vertical wall surfaces, with at least some of the prefabricated building units having at least one hollow column formwork structure. The prefabricated structural units are lowered onto an existing base on a construction site. A first floor of the building is created by placing several prefabricated building units side by side on the base. Structural stock material is applied to fill the column formwork structures and create structural columns that are connected to the structural deck. Structural stock material is applied to the horizontal top exterior surfaces of the adjacent prefabricated building units to create a single structural deck over the prefabricated building units.

From the American patent US 9,366,020 B2 a modular unit connection system is known for joining a plurality of box-shaped modular units to form a single-story or multi-story housing. The modular building units have elongated hollow structural frame members at their vertical corners and four substantially perpendicular vertical side walls extending between the vertical corner members. The vertical corner elements lie within the planes formed by the side walls of the modular units. Their vertical corner elements and their adjoining side walls are in contact with no significant distance between them. The modular units can be connected at their vertical corner elements with flat connecting plates. Threaded tie rods may extend through the hollow vertical corner members and may be coupled to tie rods that extend through the hollow vertical corner members of vertically oriented modular units.

From the European patent application EP 3 034 707 A1 a modular building system is known that comprises the horizontal or vertical coupling or superposition of prefabricated components made of reinforced concrete in order to create living spaces.

However, the previously known building modules and the buildings made from them leave behind in terms of flexibility and variability of their application, their weight, which is a strongly limiting factor, the safe statics, fire protection, soundproofing, ease of maintenance, the possibility of adding air conditioning and the complete equipment from the factory left a lot to be desired.

Detailed explanation of Figures 1 to 5 Figures 1 to 3

The hybrid building 1 according to the invention had a rectangular base area of 21 m ² with a 3.5 m wide front or entrance side V, a 3.5 m wide rear or window side R and two 6 m long side walls S. The dimensions given referred to the outer sides of the hybrid building 1. The floor slab 5 consisted of reinforced concrete (StB concrete) and was anchored with suspensions 5.2 in the basic structure of four 3-part lower horizontal metal girders 2 free of mechanical stress peaks. The height of the hybrid building 1 according to the invention was 2.7 m on the outside.

As a metal carrier 2; 3 eight U-profile metal beams made of steel were used. They each consisted of a longer central part and two shorter side parts or arms, which were connected by plate-shaped flange connections 2.1; 3.1 were attached to the middle part. The flange connections 2.1; 3.1 were in the area of the mechanical stress peaks that would occur with a one-piece metal beam of the same length. Through the flange connections 2.1; 3.1 the effect was that such voltage peaks were reduced or no longer occurred. The plate-shaped flanges 2.1; 3.1 were attached to each other by riveted joints.

The two ends of each metal support 2; 3 were attached to a total of eight perforated cuboids (four lower perforated cuboids 4.1 and four upper perforated cuboids 4.2). The fastenings were made by rivet connections or screw connections between the plate-shaped flange connections 2.2; 3.2 at the ends of the metal support 2; 3 and the respective associated vertical walls of the perforated cuboid 4.1; 4.2 with the associated receiving holes 4.1.1; 4.2.1 produced.

The perforated cuboid 4.1; 4.2 were located at the upper and lower ends of the four square concrete pillars 4. with a metal core. Your respective three other vertical walls 4.1; 4.2 had additional receiving holes 4.1.1; 4.1.2 on. These were used to connect to further hybrid buildings 1 according to the invention. In the horizontal undersides of the four lower perforated cuboids 4.1 there were also receiving holes 4.1.1. These were used to accommodate connecting devices to underlying hybrid buildings 1 according to the invention on a lower floor in a building. The connecting devices were equipped with shims 19 so that there was a space 18 between the floors. In the horizontal upper sides of the four upper perforated cuboids 4.2 there were also receiving holes 4.2.1 which were used to accommodate connecting devices to hybrid buildings 1 according to the invention located above them on a higher floor in a building. These connecting devices were also equipped with shims 19 so that there was a space 18 between the floors. The spaces 18 had a ventilation and insulating effect.

Corridor plate supports 4.2.1 made of steel were attached to the two perforated cuboids 4.1 of the front or entrance side V. These were equipped with step dampers 4.1.3, which dampened the vibrations of the corridor floor plate 9. The corridor floor plate 9 abutted in the recess 5.1 for the entrance door along the joint surface 9.1 on the horizontal floor plate 5. The joint surface 9.1 was provided with a shock-absorbing, sealing, flexible support.

The front V was covered with a vertical sandwich panel wall 6 with a recess 5.1 for the entrance door. The rear side R was also closed with a vertical sandwich panel wall 6 with a recess 10.1 for the window 10. The two side walls S were closed with full-area vertical sandwich panel walls. The horizontal ceiling O was formed by a horizontal sandwich panel ceiling 7. The horizontal sandwich panel ceiling 7 rested on the bearing surfaces 6.2 on the upper ends of the vertical sandwich panel walls 6. The vertical sandwich panel walls 6 hit the horizontal base plate 5 with their lower bearing surfaces 6.1.

The sandwich panels 1P described below were preferably used as sandwich panels. The panel systems from Wenker GmbH & Co. KG, Ahaus, Germany, were used with particular preference.

The side walls S were each covered with a vertical side wall cladding 8 made of rigid sheet steel, which served as a partition and fire protection wall to adjacent hybrid buildings 1 according to the invention (cf. Figure 4 ).

The rear or window side R, i.e. H. the outside of the hybrid building 1 according to the invention was equipped with decorative, flame-retardant and weather-resistant external facades. The front or entry side V, i.e. H. the side facing the corridor was covered with decorative, flame-retardant interior wall cladding 11.

The hybrid building 1 according to the invention could be expanded as required due to its simple and standardized, statically particularly stable structure. For example, larger hybrid buildings 1 could be made possible by the use of further square concrete columns 4 with a metal core and further, multi-part, lower and upper ones, free of mechanical stress peaks Metal supports 2; 3, which could be used in many ways. In particular, multi-storey buildings could be erected quickly and safely. Another particular advantage was that the hybrid buildings 1 according to the invention could be equipped ex works in such a way that they could be set up without any problems or were even ready for occupancy.

In this way it was not only possible to build hotels, motels, residential buildings, old people's homes, schools, office buildings, prisons and warehouses with and without elevator shafts, but also hospitals with patient rooms, isolation wards, intensive care units, doctor's rooms, treatment rooms, diagnostic rooms with medical examination equipment such as To set up X-ray machines and CT and MRT machines, ward rooms, social rooms, storage rooms, rooms for medical and other waste as well as buildings for research and development with physical, chemical, biological and microbiological laboratories and clean rooms, etc. in the shortest possible time.

Figure 4

The hybrid buildings 1 according to the invention shown in plan were as in the Figures 3 and 4th explained in more detail. They were already equipped at the factory with a recess 5.1 for the entrance door and a recess 10.1 for a window 10, so that these standardized components could easily be inserted into the front side V and the rear side R of the hybrid building 1. In addition, they were factory-equipped with a sanitary area 12, which had a washbasin 15, a toilet 14 with a water tank 14.1, a supply and ventilation shaft 13 with supply lines 13.1, a shower cubicle 16 that can be closed with a folding door 16.1 and with the aid of the folding door 17 from the living area or Functional area could be separated. The walls of the sanitary area consisted of vertical sandwich panel walls 6. The outer sides were equipped with decorative, flame-retardant and weather-resistant external facades 11. On the front side V, ie the entrance side towards the corridor 9, the interior walls were covered with decorative and flame-retardant interior wall cladding.

The two hybrid buildings 1 according to the invention were connected in the same way to other hybrid buildings 1 of the same construction, both horizontally and vertically. On the opposite side of corridor 9, an identical row of hybrid buildings 1 were also erected. In this way, a three-story building could be built in a short time and furnished according to the desired function.

The hybrid buildings 1 according to the invention were set up as hotel rooms, hotel rooms, nursing homes, nursing rooms, sick rooms, treatment rooms, doctor's rooms, isolation rooms for quarantine purposes, security rooms, shelters, rooms shielded from electromagnetic radiation and magnetic fields, computer rooms or offices.

Figure 5

The security concept for a two-story hybrid building according to the invention from four hybrid buildings 1 according to the invention comprised sandwich panel ceilings 7, vertical sandwich panel walls 6 with external facades 11 and floor panels 5 of fire resistance class F90 as well as adjacent vertical partition walls made of sandwich panel walls 6 and side wall cladding 8 of fire resistance class F30. The floor slabs 5 sandwich panel ceilings were equipped with impact sound-absorbing coverings so that the impact sound insulation RW was ≤50 dB, preferably ≤ 40 dB. The sandwich panel ceilings 7 had a sound insulation of 60 dB.

If necessary, the safety concept could be reinforced by using identical components with higher fire resistance classes such as F120 and F180. The sound insulation could also be strengthened by using appropriate sandwich panel walls 6, sandwich panel ceilings 7 and coverings. It was also easily possible to increase the protection against electromagnetic radiation and magnetic fields without changing the basic construction of the hybrid building 1 according to the invention.

Detailed explanation of FIGS. 6 to 19 Figures 6, 7 and 8

The sandwich panel 1P the Figure 6 had the dimensions 2.5 mx 6 mx 30 mm. The top layer 1.1P visible in the top view and the non-visible top layer 1.2P consisted of 2.5 mm thick, anodized aluminum sheet. The cover layers 1.1P; 1.2P had a full-surface colored coating 3P with a decorative element 3P. The circumferential opening between the cover layers 1.1P; 1.2P was closed with a circumferential U-profile rail made of anodized aluminum, which consisted of four parts. In an advantageous embodiment, the four parts of the U-profile rail 1.3P had a T-shaped cross section, so that the arms 1.3.1P of the "T" are flush with the edges of the cover layers 1.1P; 1.2P struck.

The sandwich panel 1P the Figure 7 had the shape of a disk with a diameter of 1 m and a total thickness of 30 mm. The cover layers 1.1P; 1.2P also consisted of 2.5 mm thick, anodized aluminum sheet. The circumferential opening 1.4P was with two semicircular U-profile rails 1.3P; 1.3.1P made of anodized aluminum sheet closed.

the Figure 8 shows a plan view on the edge side of the above-described embodiments of the sandwich panels 1P of FIG Figures 6 and 7 .

The sandwich panels 1P were outstandingly suitable as walls, ceilings and doors in the hybrid buildings 1 according to the invention.

Figures 9 and 13

The production of the sandwich panel 1P according to FIG Figure 9 was carried out by separating the fibers of high-temperature glass wool from alkali-resistant AR glass containing zirconium dioxide and micronized by fine grinding in a ball mill. The micronized AR glass fibers were made into a paste with an aqueous 2.5.1P suspension of slowly setting cement, so that a dough-like mass with a solids composition of 80% by weight of AR glass fibers and 20% by weight of cement resulted. The dough-like mass was pressed in a molding press with gas outlets, stamps with a corresponding profile and a square stamp area of 1 m ² at 50 ° C. to give sheet-like molding compositions with an "egg carton" configuration. The pyramids 2.6.1P according to the Figure 13 had a quadrangular base area measuring 4 mm x 4 mm and a quadrangular contact area 2.6.2P measuring 2 mm x 2 mm and were spaced 2 mm apart. The thickness of the cement-bonded AR glass fiber layers was 2 mm. The plate-shaped molding compounds 2P; 2.6P was completely cured for several days in air at room temperature.

There were two square top layers 1.1P; 1.2P of an area of 8 m ² made of 1 mm thick, degreased, hot-dip aluminized sheet metal. The contact areas 2.6.2P of four AR glass fiber layers 2P; 2.6P were coated with a high-temperature-resistant glass-metal adhesive 2.5P on a ceramic basis that cures at room temperature and first placed on the square cover layer 1.1P, after which the cover layer 1.2P was placed congruently on the 4 AR glass fiber layers. This resulted in the mineral fiber layer 2; 2.6aP ("simple egg carton" configuration) channels 2.2P that run parallel to the top layers 1.1P; 1.2P ran and channels 2.3P that ran orthogonal to the parallel channels 2.2P.

After the high-temperature-resistant binder or adhesive 2.5P had fully cured, the circumferential opening 1.4P between the cover layers 1.1P; 1.2P all around with four appropriately dimensioned U-profile rails 1.3P; 1.3.1 P with a T-shaped cross-section (cf. Figures 6 to 8 ) closed by inserting the U-profile into the circumferential opening 1.4P until the arms of the "T" are flush with the edges 1.5P top layers 1.1P; 1.2P completed.

In a further embodiment, appropriately dimensioned U-profile rails 1.3P without a T-shaped cross-section 1.3.1P were used, which were pushed over the circumferential edges 1.5P in a clamp-like manner. This had the advantage that the mineral fiber layer 2P was no longer contacted at its edges. In the following these U-profile rails 1.3P were always used

The U-profile rails 1.3P had openings for pressure equalization with the environment.

The sandwich panels 1P of this type had a significantly lower weight than structurally identical sandwich panels that were completely filled with glass wool. In addition, they showed excellent sound and thermal insulation. They were fire-retardant and were not destroyed by red heat. They were therefore outstandingly suitable as components for the hybrid building 1 according to the invention.

Figures 10 and 14

The manufacture of the sandwich panel 1P of the Figure 10 was done by as with Figure 9 described square, 1 m ² plate-shaped molding compositions with an "egg carton" configuration 2.6P. The plate-shaped molding compounds 2.6P; 2.6.1 P differ from those of the Figure 9 only by the fact that instead of the pyramids 2.6.P with a square floor plan according to the Figure 13 Pyramids 2.6.1 P with a circular floor plan but comparable size according to the Figure 14 were used. The four plate-shaped molding compounds 2.6P; 2.6.1 P were as in Figure 9 written with the surface of the two cover layers 1.1P; 1.2P firmly connected. Then 2.6.2P of the sheet-like molding compounds 2.6P; 2.6.1 P fleece 2.7P made of polycrystalline aluminum oxide wool glued on with a high-temperature-resistant inorganic glass adhesive 2.5P. The other top layer 1.1P or 1.2P was then combined with the four further plate-shaped molding compounds 2.6P; 2.6.1 P glued on the other side of the fleece 2.7P in such a way that the raised contact surfaces 2.6.2P of the plate-shaped molding compounds 2.6P; 2.6.1 P opposite each other. Finally, the circumferential opening 1.4P between the edges 1.5P of the cover layers 1.1P; 1.2P closed with U-profile rails as in example 9.

The result was a sandwich panel 1P with a mineral fiber layer 2P of a "double egg carton" configuration 2.6P with a thickness of about 6 mm, which was significantly lighter than a comparable sandwich panel, the space between which was completely filled with glass wool. The 1P sandwich panel had excellent sound and thermal insulation and was still fire-retardant even when it was red heat. Sandwich panels 1P of this type were therefore outstandingly suitable as components for the hybrid building 1 according to the invention.

Figures 11 and 15

The sandwich panel 1P the Figure 11 was made by following as at Figure 9 described sheet molding compositions 2.6P with an "egg carton" configuration. These differed from the sheet-like molding compounds 2.6P Figure 9 and the Figure 10 only in that pyramids 2.6.1 P with a hexagonal plan and hexagonal contact surfaces 2.6.2P according to the Figure 15 were used. There were three layers of this plate-shaped molding compound 2.6P in the Figure 11 superimposed in the manner shown, so that a "triple egg carton" configuration 2.6cP resulted as a mineral fiber layer 2P. The circumferential opening 1.5P was as in Figure 9 described closed with circumferential U-profile rails 1.3P. The outer surfaces of the cover layers 1.1P; 1.2P coated with a 3P coating made of a powder coating that is heat-resistant up to 250 ° C.

The sandwich panel 1P had a total thickness of about 10 mm and was significantly lighter than a comparable sandwich panel, the space between which was completely filled with rock wool. This 1P sandwich panel also had excellent sound and thermal insulation and was fire-retardant even when the coating was burned down or charred. The sandwich panel 1P was therefore outstandingly suitable as a component for the hybrid building 1 according to the invention.

Figures 12 and 15

The sandwich panel 1P the Figure 12 became like with the Figure 9 produced by five layers of the sheet-shaped molding compositions 2.6P with the "egg carton" configuration, as in the Figure 12 shown, superimposed so that a "fivefold egg carton" configuration 2.6dP resulted.

The sandwich panel 1P had a total thickness of about 14 mm and was significantly lighter than a comparable sandwich panel, the space between which was completely filled with rock wool. This 1P sandwich panel also had excellent sound and thermal insulation and was fire-retardant even when it was red heat and did not deform. The sandwich panel 1P was therefore outstandingly suitable as a component for the hybrid building 1 according to the invention.

Figure 16

The sandwich panel 1P the Figure 16 was made by first starting with the Figure 9 described dough-shaped mass plate-shaped molding compositions 2.8P with a Manufactured "corrugated iron" configuration. The parallel, arranged webs 2.10.1P were 4 mm apart and were 8 mm high. Their wall thickness was 2 mm. The contact areas 2.6.2P were 4 mm wide. The channels 2.2P in the webs had a maximum inside width of 6 mm.

A layer of the plate-shaped molding compounds 2.8P was bonded to the cover layers 1.1P and 1.2P with a high-temperature-resistant glass-metal adhesive on the contact surfaces 2.6.2P. The circumferential opening 1.5P between the cover layers 1.1P; 1.2P became like the Figure 9 described closed with U-profile rails.

The resulting sandwich panel 1 had a total thickness of about 10 mm. It was significantly lighter than a comparable sandwich panel, the space between which was completely filled with polycrystalline aluminum oxide wool. The sound insulation, thermal insulation and fire retardancy were excellent. The sandwich panel 1P was therefore outstandingly suitable as a component for the hybrid building 1 according to the invention.

Figure 17

the Figure 17 shows a mineral fiber layer 2P which contained differently shaped depressions and depressions 2.9P. The mineral fiber layer 2P had a maximum layer thickness of 4 mm. The maximum depth of the depressions and depressions 2.9P was 3 mm. The mineral fiber layer 2P was molded from the at Figure 9 dough-like mass described.

A sandwich panel 1P made with this mineral fiber layer 2 had the same excellent properties as described above.

Figure 18

The sandwich panel 1P the Figure 18 was produced by cutting paper webs 2.7P made of high temperature resistant polycrystalline aluminum oxide wool with the Figure 9 2.5.1P described suspension, so that an aluminum oxide wool with a solids content of 90% by weight of aluminum oxide and 10% by weight of cement resulted. The impregnated paper webs 2.7P were folded in the wet state, so that the distance from the tips to the depressions in the folded paper webs 2.7.1 P was 5 mm. The folded, impregnated paper webs 2.7.1 P were cured in air at room temperature. Two square, 4 m ² covering layers 1.1P; 1.2P made of 1.5 mm thick stainless steel were glued over the entire surface to the 2.7P paper webs. A layer of the hardened, folded paper webs 2.7.1P was then glued onto a cover layer 1.1P or 1.2P on the paper webs 2.7P. On top of this, paper webs 2.7P and another layer of the hardened, folded paper webs 2.7.1P were fixed. Then paper webs 2.7P were placed again and a third layer of the hardened folded paper webs 2.7.1 P was fixed. Their tips were glued to the paper webs 2.7P on the other cover layer 1.1P or 1.2P. A high temperature resistant inorganic glass adhesive 2.5P was used for the bonding.

The sandwich panel 1P was about 20 mm thick and had a mineral fiber layer 2P with a "corrugated cardboard" configuration 2.8P, which was particularly mechanically stable. The weight saving compared to a comparable sandwich panel, the space of which was completely filled with high-temperature-resistant aluminum oxide wool, was considerable. The thermal insulation, sound insulation and fire retardancy were excellent. This sandwich panel 1P was therefore also outstandingly suitable as a component for the hybrid building 1 according to the invention.

Figure 19

The sandwich panel of the Figure 19 was produced by folding paper webs 2.7P made of high-temperature-resistant aluminum oxide wool and glued to a 1.5 mm thick cover layer 1.1P or 1.2P made of stainless steel using a high-temperature-resistant inorganic glass-metal adhesive 2.5P. The free sides of the folded paper webs 2.7.1P were glued with mineral fiber fleeces 2.11P made of aluminum silicate wool. Folded paper webs 2.7.1P were placed again on the mineral fiber fleece 2.11P and glued so that their channels 2.3P were arranged orthogonally to the channels 2.2P of the first layer of folded paper webs 2.7.1P. Finally, the free sides of these folded paper webs 2.7.1P were glued to the other cover layer 1.1P or 1.2P, and the circumferential opening 1.5P was closed circumferentially with U-profile rails 1.3P as described above.

The sandwich panel 1P was about 22 mm thick and showed a considerable saving in weight compared to a comparable sandwich panel, the space of which was completely filled with high-temperature-resistant aluminum oxide wool. The 1P sandwich panel was mechanically particularly stable and had excellent thermal insulation, Sound insulation and fire retardancy.
