Description

[0001] Floor of a house and a house comprising at least one such floor

[0002] Field of the Invention

[0003] The present invention relates to the field of construction, more specifically to a floor of a house and a house comprising this floor, the design of which is efficient in terms of optimizing the ratio of floor area (FA) to gross floor area (GFA), as well as in terms of construction.

[0004] Background of the Invention

[0005] The ratio or coefficient of floor area (FA) to gross floor area (GFA), i.e. FA / GFA, is important in the construction of houses, especially apartment buildings, from the point of view of the overall economics of residential construction. For commonly constructed apartment buildings, the value of this coefficient currently ranges from 0.750 to 0.800. For example, increasing the FA / GFA coefficient by 0.08, e.g. from 0.780 to 0.860, will improve the overall economics of residential construction by almost 15%. It is therefore desirable to develop a house that is efficient in terms of the FA / GFA coefficient, i.e. the ratio between the areas that can be sold and the areas that are part of the building and cannot be sold. Such a technical solution of apartment building for affordable housing is unknown in the Czech Republic or abroad.

[0006] Summary of the Invention

[0007] According to the invention, the above problem is solved by a floor of a house and a house comprising such a floor.

[0008] The floor of the house of the present invention comprises a pair of rectangular internal modules arranged side by side, in which a staircase, an elevator shaft, and a main section of a building corridor are arranged, with the staircase and elevator shaft opening into the main section of the building corridor opposite each other and located symmetrically along the common axis of the staircase and elevator shaft, with the common axis of the staircase and elevator shaft being parallel, preferably identical, to the line of contact between the internal modules; and a number of rectangular external modules arranged around the perimeter of the pair of internal modules.

[0009] Internal and external modules can be rectangular or square, preferably rectangular, and can have virtually any length of side, preferably a length of side of 0 to 10000 mm, 2500 to 10000 mm, preferably 3000 to 10000 mm, more preferably 4000 to 7800 mm, most preferably 5000 to 7700 mm. Typical lengths of the sides of modules can be, for example, 3000, 4000, 4100, 4500, 4800, 5000, 5400, 6000, 6500, 6600, 7000, 7100, 7500, 7700, 7800, 7900, 8000, 9500, and 10000 mm. Typical internal modules can have dimensions of, for example, 7700 x 5000 mm, 7800 x 4800 mm, 7800 x 5000 mm, 8000 x 4500 mm, and 10 000 x 5000 mm. Typical external modules can have dimensions of, for example, 3000 x 4500 mm, 3000 x 5400 mm, 3000 x 6000 mm, 3000 x 7900 mm, 4000 x 4800 mm, 4000 x 5000 mm, 4000 x 6000 mm, 4000 x 7100 mm, 5000 x 5000 mm, 5000 x 5400 mm, 5400 x 5000 mm, 5400 x 5400 mm, 6000 x 7100 mm, 6000 x 7700 mm, 6000 x 7900 mm, 6500 x 5000 mm, 6600 x 5000 mm, 7000 x 4500 mm, 7000 x 4800 mm, 7000 x 5000 mm, 7000 x 5400 mm, 7500 x 4800 mm, 7700 x 5000 mm, 7800 x 4800 mm, 7800 x 5000 mm, 7800 x 6000 mm, 8000 x 4500 mm, 8000 x 5000 mm, 8000 x 5400 mm, 8000 x 6000 mm, 9500 x 5000 mm, 10 000 x 4100 mm, 10 000 x 5000 mm and 10 000 x 5400 mm. When specifying module dimensions, the order of dimensions is not important, i.e. the specified dimension of 4000 x 6000 mm includes both a module with dimensions of 4000 x 6000 mm and a module with dimensions of 6000 x 4000 mm.

[0010] The external modules are arranged around the perimeter of the pair of internal modules and may be arranged around the pair of internal modules in one or more rows, preferably one to three rows, more preferably in one or two rows, most preferably in one row, wherein these rows of modules may be preferably complete, i.e. they may completely surround the pair of internal modules, e.g. in the case of the first row of external modules, the pair of internal modules may be surrounded by ten external modules, or they may be incomplete, i.e. one or more external modules are not present, e.g. in the case of the first row of external modules, the pair of internal modules may be surrounded by less than ten external modules. The first row of external modules is preferably complete, especially if it is the only row, while the second and any subsequent rows of external modules are preferably incomplete. External modules with different dimensions can be combined with each other in rows. The adjacent sides of neighbouring modules have preferably the same dimensions, wherein such a neighbouring module can be made up of two or more smaller modules, where the sum of the dimensions of the sides adjacent to the neighbouring module (or modules) is equal to the dimension of the respective adjacent side of the neighbouring module (or the sum of the dimensions of the respective adjacent sides of the neighbouring modules). Most preferably, the floor of the present invention comprises external and internal modules of the same dimensions. This provides variability both in the case of detached houses and in the case of groups of houses, making it possible to meet architectural requirements, requirements arising from the shape of the parcel, etc.

[0011] The staircase is preferably a double-flight staircase, preferably with a landing. The main section of the building corridor is defined by the width of the wider of the staircase and elevator shaft, usually the width of the staircase. The main section of the building corridor may be connected to other sections of the building corridor in any direction as needed, preferably sections whose axis is perpendicular to or identical to the axis of the main section of the building corridor. These other sections of the building corridor may extend beyond the boundaries of the internal modules, pass through the external modules, and even reach the outer perimeter of the floor, for example on the first floor, thus providing access to the house from the outside. The staircase, elevator shaft, and main section of the building corridor, in the longitudinal dimension along the common axis of the staircase and elevator shaft, preferably extend across the entire width of the internal modules defined by the dimension of the line of contact between the internal modules. Another object of the present invention is a house comprising one or more of the abovedescribed floors of the present invention. For ease and efficiency of construction, one house comprises preferably floors of the same type in terms of the number, size, and arrangement of internal and external modules, but a house may also comprise floors of different types, which can result in architecturally interesting houses. In embodiment, where the house comprises floors of the same type, there may be a different number of housing units of varying sizes on different floors. In one house, different layouts can thus alternate on individual floors. A house is preferably an apartment building, but it may include non-residential areas. The house and floor of the present invention can be constructed from any building material, e.g. using bricks, ceramic or aerated concrete blocks and bricks, reinforced concrete, e.g. reinforced concrete prefabricated or monolithic frame, steel, e.g. steel LGSF (Light Gauge Steel Frame) structure, or 2D LGSF panels, wood, e.g. wooden CLT (Cross-Laminated Timber) panels, sandwich panels, etc. The house and floors are preferably constructed using a reinforced concrete frame, more preferably a prefabricated reinforced concrete frame, wall panels, more preferably 2D LGSF panels, and a reinforced concrete ceiling, preferably prefabricated ceiling panels.

[0012] To achieve maximum speed and precision in construction, a prefabricated reinforced concrete frame with prefabricated ceiling panels is preferably used as the basic structural system. Such a prefabricated frame includes columns spanning one or two floors. The columns have a T- or L-shaped cross-section and are founded on prefabricated monolithic footings. The columns are always located in the corners of individual modules and, where necessary, along the sides of the modules, e.g. in the case of long sides, and are interconnected by means of horizontal beams that are inserted into pre-prepared pockets in the columns. Ceiling panels are then installed on these beams. All elements of the frame are penetrated between each other, and any voids are filled with concrete grout. This will result in the entire frame structure becoming rigidly monolithic. Openings in the ceiling structure are made using steel replacements and shortened panels. A prefabricated staircase structure can be placed in these openings. Similarly, openings for installation distribution systems are made. In addition, the prefabricated system may include panel walls, e.g. around staircases, and other prefabricated elements, e.g. prefabricated segments for elevator shaft, which will be stacked on top of each other. Entire rooms can also be prefabricated, especially small rooms such as bathrooms, toilets, storage rooms, etc.

[0013] The interior walls between apartments are preferably made of 2D LGSF panels. The exterior walls are also preferably made of 2D LGSF and are suspended from the load-bearing structure of the frame. This preferable solution further contributes to increasing the FA / GFA coefficient. This structural framing system allows individual houses to be treated as building blocks, which can be connected and combined in various ways to easily and efficiently create continuous rows of houses and blocks of houses, including corner sections. Furthermore, this system makes it very easy to change the spans of individual modular axes, thus changing the overall width and length of the house by several meters. It is thus possible to parametrically reduce or enlarge an apartment building and also to easily reduce or enlarge the overall size of all or only selected (non-)residential units. This characteristic is very important when placing houses on smaller parcels, because even when the spans are changed, it is possible to maintain the overall concept of the structural and technical design of the house, and the project documentation does not need to be complicated ly reworked.

[0014] According to the present invention, the above-described floor and the house made of prefabricated reinforced concrete frame with prefabricated ceiling panels are preferably provided.

[0015] The inventors have managed to increase the FA / GFA coefficient to the value of 0.878, which represents high efficiency in the use of space and thus increased economic profitability in the construction of the house. Implementation costs do not have a significant impact on the overall improvement, because increasing the FA / GFA coefficient does not change the total volume of the building, but only changes the ratio between the floor areas of residential or non-residential units and the common areas of the apartment building, i.e. between areas that can be sold and areas that are part of the building and cannot be sold.

[0016] The present invention will be further described by way of exemplary embodiments with reference to the figures in drawings. An average expert will clearly see that a number of changes, modifications, variations, or adaptations of the invention as described herein may be made without departing from the scope of the invention.

[0020] Figs. 15.1 to 15.9 show examples of the sets of houses of the present invention.

[0021] Examples of the invention embodiments

[0022] Example 1

[0023] The floor of the house shown in Figs, la, lb, and lc comprises a pair of rectangular internal modules la and lb with a dimension of 7700 x 5000 mm arranged side by side, in which staircase 2, elevator shaft 3, and the main section 4 of the building corridor are arranged. The double-flight staircase 2 with a landing and the elevator shaft 3 open into the main section 4 of the building corridor opposite each other and are located symmetrically along the common axis A of the staircase and elevator shaft. The common axis A of staircase 2 and elevator shaft 3 is identical to the line 5 of contact between the internal modules. The building corridor consists of other sections and its floor plan does not extend beyond the boundaries of the internal modules. One complete row of rectangular external modules 6 with a dimension of 7700 x 5000 mm is arranged around the perimeter of the pair of internal modules la and lb.

[0024] The floor of the house is made of a prefabricated reinforced concrete frame (see especially Fig. lb) comprising columns 7 located in the corners of individual modules and in the corners of the area for staircase 2 and elevator shaft 3. The columns 7 are interconnected by means of horizontal beams 8, on which ceiling panels are installed (not shown). Panel walls are installed around the area for staircase, and the elevator shaft is made of prefabricated segments 10 stacked on top of each other.

[0025] There are eight residential units on the floor, GFA = 485.1 m2, FA = 408.4 m2, FA / GFA = 0.842.

[0027] The floor of the house shown in Figs. 2a, 2b, and 2c is designed as the floor in Example 1 (Figs, la, lb, lc), with the difference that it comprises only six residential units. As a result, the building corridor is linear and has a smaller floor area, which, together with the removal of partitions between apartments, leads to an increase in the FA / GFA coefficient. There are six residential units on the floor, GFA = 485.1 m2, FA = 419.0 m2, FA / GFA = 0.864.

This leads to a further increase in the FA / GFA coefficient. There are five residential units on the floor, GFA = 485.1 m2, FA = 422.4 m2, FA / GFA = 0.871. If the same change compared to Example 2 were made in the lower half of the floor, there would be a further increase in the FA / GFA coefficient - four residential units, GFA = 485.1 m2, FA = 425.7 m2, and FA / GFA = 0.878.
