Description

Technical Field

[0001] This application belongs to the field of residential building technology, and specifically relates to a variable interior space building system throughout its entire life cycle. Background Technology

[0002] Throughout the entire life cycle of a residential building, as family structures and lifestyles change, people's demand for adjustments to the interior layout and electromechanical upgrades becomes increasingly prominent.

[0003] However, in traditional residential buildings, interior spaces are often restricted by shear walls and utility shafts. While modifications can create localized spatial flexibility, the inherent limitations of the existing building structure, such as the location of short-limb shear walls and the height of their connecting beams, mean that spatial alterations must adapt to the building structure. This limits flexibility to partial modifications and prevents global adaptation to changing resident needs. Furthermore, since shared facilities such as pipes and equipment are typically located within interior spaces, maintenance and upgrades require access to residents' personal spaces, disrupting daily life, potentially damaging renovations, and resulting in complex and costly renovations. In addition, the dense arrangement of interior walls and beams further restricts the free layout and long-term adaptability of space, hindering sustainable use throughout its entire lifecycle. Utility Model Content

[0004] Based on the above analysis, the present invention aims to provide a full-lifecycle indoor variable space building system to solve one or more of the above-mentioned problems existing in the prior art.

[0005] The purpose of this utility model is achieved as follows: A life-cycle variable interior space architectural system, comprising: The core tube serves as a lateral force resisting structural system. The steel-concrete composite structure floor slab is connected to both sides of the core tube and is used to transfer horizontal loads to the core tube. The steel-concrete composite structure floor slab has floor slab structural units and hidden beam frames that support the floor slab structural units. The hidden beam frames are integrated with the floor slab structural units by pouring concrete to form a steel-concrete composite structure floor slab. The hidden beam frames are connected to the core tube. The hidden beam frames are connected to multiple frame support columns. The building exterior walls and the partition walls form the interior space of each unit. The interior space has a centralized water use space and a non-water use space, and the number of frame support columns in each unit's interior space does not exceed one.

[0006] Furthermore, the core tube and frame support columns support the steel-concrete composite structure floor slabs, while the building exterior walls and partition walls are arranged separately from the frame support columns.

[0007] Furthermore, the location of the building's exterior wall on one side of the centralized water use space can be recessed towards the interior space or extended towards the exterior space.

[0008] Furthermore, the semi-outdoor space formed by the inward recess of the building's exterior walls serves as a backyard and equipment platform. The backyard is connected to the front yard, and the front yards of two or more adjacent households are connected by a shared vestibule between the elevator shaft and the stairwell.

[0009] Furthermore, the concealed beam frame includes multiple frame beams arranged horizontally and vertically in the plane. The frame beams located at the gable wall are made of bending-resistant steel beams, while the frame beams at other locations are concealed beams. The concealed beams are hollow steel beams with through holes that connect to the internal space to allow concrete to flow in.

[0010] Furthermore, the frame support columns include edge support columns and intermediate support columns; wherein, the intermediate support columns are located in the middle of the partition wall, or in the central area of ​​the interior space; The edge support columns are located on the exterior wall of the building or on the outer side of the exterior wall.

[0011] Furthermore, the building's exterior walls and partition walls are constructed using lightweight blocks or panels that meet sound insulation requirements, and the interior space of each unit is divided into multiple independent spaces by lightweight partition walls or movable partition walls.

[0012] Furthermore, a drainage riser is installed on the exterior side of the residence near the centralized water use space; various types of water appliances are arranged in the centralized water use space, and horizontal drainage pipes connected to the water appliances extend outdoors and connect to the drainage riser.

[0013] Furthermore, an elevated floor is laid above the steel-concrete composite floor slab, and a suspended ceiling is installed below the steel-concrete composite floor slab.

[0014] Furthermore, a first suspended ceiling is provided below the steel-concrete composite structure floor slab in the non-water-use area, and radiant cooling modules and connecting pipelines, lighting power pipelines and lamps, network pipelines and network equipment are laid in the space between the first suspended ceiling and the bottom surface of the steel-concrete composite structure floor slab in this area. A second suspended ceiling is installed below the steel-concrete composite floor slab within the centralized water use area. The second suspended ceiling has exhaust pipes installed in the space between the bathroom and kitchen areas and the bottom surface of the steel-concrete composite floor slab in that area, and passes through the exterior wall to connect with the outside. The distance between the bottom and top layers of the first suspended ceiling is the nominal board thickness, which is as low as 400mm.

[0015] Compared with existing technologies, the variable indoor space building system provided by this utility model innovatively proposes a design concept of "from developer's expectations to resident customization".

[0022] The explanation of "whole life cycle": A whole life cycle home refers to a home that can not only adapt to the layout requirements brought about by changes in family structure, including from two-person families to multi-child families to multi-generational families; but also meet the usage requirements of residents of different age groups, such as children, teenagers, adults and the elderly. In particular, it should meet the different usage requirements of home-based elderly care, such as wheelchair access throughout the entire area, continuous handrails, observation corridors for the elderly, and layout of companionship spaces; and also meet the new living scenario needs arising from improved economic conditions, equipment upgrades, and changes in lifestyle.

[0023] Example 1 A specific embodiment of this utility model discloses a variable interior space building system throughout its entire life cycle. This system is a globally variable living space building system for families and residences throughout their entire life cycle. Figures 1 to 4 As shown, the structure includes a core tube 600, with reinforced concrete composite floor slabs 2 connected to both sides of the core tube 600. The core tube 600 serves as a lateral force resisting structural system, and the reinforced concrete composite floor slabs 2 are used to transfer horizontal loads to the core tube 600. The reinforced concrete composite floor slabs 2 have floor slab structural units 20 and hidden beam frames supporting the floor slab structural units 20. The hidden beam frames are integrated with the floor slab structural units 20 by pouring concrete to form an integral structure of the reinforced concrete composite floor slab 2. The hidden beam frames are connected to the core tube 600. The hidden beam frames are connected to multiple frame support columns 17, and the building exterior walls and partition walls 700 form the interior space of each unit.

[0024] In one preferred embodiment, the indoor space includes a centralized water-use space 100 and a non-water-use space 200, and the number of frame support columns 17 in each household's indoor space does not exceed one. The number of frame support columns 17 here does not include those located on the walls or corners of the indoor space. That is, the frame support columns 17 are preferably located on the exterior walls of the building, the partition walls 700, or at corners, and the number of frame support columns 17 located away from the walls or corners within the indoor space is 0 or 1.

[0025] Since the interior space has no frame support column 17 or only one frame support column 17, the interior space is square and has no visible beams. The interior space of each household is divided into multiple independent spaces by lightweight partition walls or movable partition walls, so as to realize the variable layout of the interior space.

[0026] In one alternative embodiment, the concealed beam frame is connected to the frame support columns 17 of the lower-level steel-concrete composite floor slab 2 via frame support columns 17; the lowest-level concealed beam frame is connected to the foundation via frame support columns 17. Vertical loads are transmitted through the frame support columns 17 of each level.

[0027] In one alternative embodiment, the core tube 600 and the frame support columns 17 support the reinforced concrete composite floor slab 2, and the building exterior walls are arranged separately from the frame support columns 17. That is, unlike traditional buildings where shear walls are directly cast into the exterior wall area with concrete and integrated with insulation and decoration, this embodiment uses a separate structure where the two are independently set up. The frame support columns support the reinforced concrete composite floor slab 2, and the exterior walls separate the interior and exterior spaces. This embodiment uses only the core tube 600 and the frame support columns 17 to support the reinforced concrete composite floor slab 2, allowing for the modification of the building exterior walls without safety issues, and creating convenient conditions for subsequent spatial layout modifications—something traditional building systems cannot achieve.

[0028] In this embodiment, the concealed beam frame is a rectangular frame structure in plan. The frame support columns 17 include multiple edge support columns 17.1 and multiple intermediate support columns 17.2. The edge support columns 17.1 are arranged at the concealed beams at the edge of the concealed beam frame, and the intermediate support columns 17.2 are arranged at the concealed beams at the middle position of the concealed beam frame. The intermediate support columns 17.2 are located in the middle of the partition wall 700, or in the middle area of ​​the interior space. The edge support columns 17.1 are located at the exterior wall of the building or on the outside of the exterior wall of the building, so as to achieve the regularity and freedom of the interior space.

[0029] In one preferred embodiment, one of the building's exterior walls can be recessed towards the interior space or extended towards the exterior space, allowing for this adjustment during initial construction or later renovations. Preferably, the exterior wall 14 located on the side of the centralized water supply space can be recessed towards the interior space or extended towards the exterior space. For example, a semi-outdoor space formed by the inward recess of one building's exterior wall serves as a backyard 400 and an equipment platform area 500. The backyard 400 is connected to the front yard 300, and adjacent front yards 300 are connected via a shared vestibule 800 between elevator shafts and stairwells. The equipment platform area 500 is positioned in a corner of the backyard 400, enabling equipment maintenance without entering the property.

[0030] In one alternative embodiment, the concealed beam frame includes multiple frame beams arranged horizontally and vertically in a planar layout. Each frame support column 17 is connected to the concealed beam frame at a connection node of two or more frame beams. The frame beams located at the gable end are shaped steel beams 16, while the frame beams at other locations are concealed beams, which are hollow steel beams 13. The main function of the shaped steel beams 16 is to enhance the overall torsional stiffness of the building to resist horizontal loads. The hollow steel beams 13 have through holes that connect to the internal space for concrete flow. The steel-concrete composite floor slab 2 is an integral rigid horizontal member formed by cast-in-place concrete from floor slab structural units 20 with a thickness of not less than 100mm and the concealed beam frame, effectively transferring horizontal loads to the core tube 600. When pouring concrete for the building floor slab, various floor slab structural unit 20 forms are available, such as steel truss floor deck 20.1 or reinforced concrete composite slab 20.2, see [reference]. Figure 7 If a steel truss floor deck 20.1 is selected, the bottom formwork of the steel truss floor deck 20.1 is used as the mold for concrete pouring; if a reinforced concrete composite slab 20.2 is selected, the precast slab of the reinforced concrete composite slab 20.2 is used as the mold for concrete pouring. Concrete flows into and fills the internal space of the steel beam through the through holes. After the concrete solidifies, it forms an integrated steel-concrete composite floor slab 2 with the steel beam 13 and the floor slab structural unit 20. The hollow structural steel beam 13 provides structural support without occupying the space below, meeting the flexible and adaptable requirements of a large indoor space.

[0031] To improve sound insulation performance, the building's exterior walls and partition walls 700 can be constructed using expanded clay bricks or slabs, achieving a sound insulation level of ≥50 dB. A raised floor is laid above the reinforced concrete composite structure floor slab 2 to further enhance sound insulation performance.

[0032] In this embodiment, the concealed beam near the balcony side of the concealed beam frame is also connected to the balcony cantilever steel beam 18 and the balcony secondary steel beam 19.

[0033] In this embodiment, the core tube 600, a central structural core composed of reinforced concrete walls of elevator shafts, stairwells, and shared vestibules 800, is the building's main lateral force resisting structural system, used to withstand wind loads or seismic forces. The shared vestibule 800 is a public transportation space shared by two or more households within the same unit, conforming to fire safety regulations. Serving as a shared vestibule for elevator lobbies and stairwells, it acts as a hub connecting vertical transportation and the entrance to the unit. The atrium 300, located outside the resident's entrance door, is a semi-public, semi-outdoor transitional area connecting the shared vestibule 800 and the backyard 400, forming the starting point of the spatial sequence of "public-semi-public-personal space." The backyard 400, a dedicated platform located outside the outer wall on one side of the centralized water supply area, integrates vertical public utility pipe shafts and connects to the atrium 300 via a gate. Adjacent to the equipment platform area 500, it is a key external space for achieving "maintenance without entering the unit." The equipment platform area 500 is located outside the exterior wall on one side of the centralized water supply space. It is a dedicated platform for placing household equipment such as air source heat pump units and fresh air units, facilitating equipment operation and maintenance without affecting the indoor environment. A low door is installed in the shared anteroom 800, which symbolically separates the two anteroom areas 300, defining the sense of territory while maintaining visual connectivity of the space.

[0034] In one alternative embodiment, the interior space comprises a centralized water-use space 100 and a large, non-water-use space 200, and employs an externally mounted drainage riser 1. Specifically, the drainage riser 1 is located on the exterior side of the residence near the centralized water-use space 100; various types of water-using appliances are arranged within the centralized water-use space 100, and horizontal drainage pipes 3 connected to these appliances extend outdoors and connect to the drainage riser 1. The reinforced concrete composite floor slab 2 within the centralized water-use space 100 is treated as a single lowered slab, forming a sunken space within the lowered slab area, where the horizontal drainage pipes 3 are arranged. This externally mounted drainage riser and centralized arrangement of water-using appliances not only achieves same-floor drainage but also reduces noise sources and the risk of leakage.

[0035] It should be noted that the external placement of the drainage riser 1 in this embodiment is suitable for southern regions. If the drainage riser is placed externally in cold northern regions, insulation or electric heating measures are required to prevent freezing.

[0036] In this embodiment, the centralized water-using space 100 includes one or more of the following: toilet 101, housekeeping room 102, kitchen 103, and other indoor water-using spaces. These other indoor water-using spaces may include spaces for washing clothes, mopping, etc. The number of toilets 101, housekeeping room 102, kitchen 103, and other indoor water-using spaces can all be one or more. Of course, it is understood that various types of water-using spaces can be set up within the effective waterproof range of the centralized water-using space according to actual needs.

[0037] In this embodiment, an adjustable floor support 4 is provided in the sunken space of the lowered slab to form a first elevated layer 5; the horizontal drain pipes 3 connected to various water appliances are all placed in the first elevated layer 5.

[0038] In this embodiment, the first elevated floor 5 is under a rigid waterproof concrete slab. The rigid waterproof slab covers the entire plane of the centralized water space 100, and no downward water leakage will occur within this area.

[0039] In this embodiment, a second elevated floor 6 is provided above the steel-concrete composite structure floor slab 2 within the non-water space 200. Floor heating pipes, fresh air system pipes 7 and electrical wiring are laid in the second elevated floor 6.

[0040] Furthermore, a first suspended ceiling 8 is installed beneath the steel-concrete composite floor slab 2 within the non-water-use space 200. Radiant cooling modules and connecting pipelines, lighting power lines and lamps, and network lines and equipment are laid in the space between the first suspended ceiling 8 and the bottom surface of the steel-concrete composite floor slab 2 in this area. A second suspended ceiling 9 is installed beneath the steel-concrete composite floor slab 2 within the centralized water-use space 100. Exhaust pipes 10 are laid in the space between the second suspended ceiling 9 and the bottom surface of the steel-concrete composite floor slab 2 in this area. The exhaust pipes 10 include a kitchen exhaust pipe 10.2 and a bathroom exhaust pipe 10.1.

[0041] In this embodiment, a surface layer 11 is laid above both the first elevated floor 5 and the second elevated floor 6; wherein, the surface layer 11 above the first elevated floor 5 and the surface layer 11 above the second elevated floor 6 are at the same height; of course, the surface layer 11 above the first elevated floor 5 may also be slightly lower than the surface layer 11 above the second elevated floor 6, with a difference of no more than 15mm.

[0042] In this embodiment, the distance between the bottom surface of the first suspended ceiling 8 and the surface layer 11 above the second open floor 6 is called the nominal plate thickness. By setting multiple steel beams 13 in the steel-concrete composite structure floor slab 2 of the residential building, structural support is provided without occupying the space below, so that the nominal plate thickness can be made thinner. Optionally, the nominal plate thickness can be as low as 400mm.

[0043] In this embodiment, the first suspended ceiling 8 can be flush with the second suspended ceiling 9 for a more aesthetically pleasing appearance. Of course, some parts of the second suspended ceiling 9 will also be lower than the first suspended ceiling 8, making the space above some parts of the second suspended ceiling 9 larger, allowing for the installation of more or thicker pipes, such as kitchen exhaust pipe 10.2 and bathroom exhaust pipe 10.1, which can be adjusted as needed.

[0044] In this embodiment, the residential building adopts a centralized layout of water-using spaces and a regional anti-leakage design. The water-using spaces are centrally located on one side of the living space. This space, along with its adjacent front yard 300, backyard 400, and equipment platform area 500, are uniformly lowered and feature a systematic anti-leakage design to prevent leakage during use or after renovation. Specifically, the exterior walls of the residential building adjacent to the centralized water-using space 100 include the front yard 300, backyard 400, and equipment platform area 500. The reinforced concrete composite floor slabs 2 within the areas of the front yard 300, backyard 400, and equipment platform area 500 are all lowered, for example, by 100mm, in line with the centralized water-using space 100, and are designed as rigid waterproof floor slabs.

[0045] In this embodiment, the drainage riser 1 is arranged on the outside of the enclosure structure 12; the drainage riser 1 includes a vertically parallel toilet sewage riser 1.1, a kitchen sewage riser 1.2, and a rainwater riser 1.3; wherein, the toilet sewage riser 1.1 is connected to the toilet horizontal drainage pipe 3.1 in the toilet 101 and the housekeeping room 102, and the kitchen sewage riser 1.2 is connected to the kitchen horizontal drainage pipe 3.2 in the kitchen 103; the top inlet of the rainwater riser 1.3 is connected to the roof drainage ditch.

[0046] In this embodiment, the horizontal drainage pipe 3 extends through the outer wall 14 on one side of the centralized water use space and continues until it connects to the drainage riser. The steel beam 13 adjacent to the drainage riser 1 is lowered, meaning the top surface of the steel beam 13 at this location is lower than the height of the horizontal drainage pipe 3, preventing the hidden beam at this location from obstructing the connection between the horizontal drainage pipe 3 and the drainage riser.

[0047] In one alternative implementation, specifically, as Figure 5 As shown, the hollow steel beam 13 has a top plate 13.1, a bottom plate 13.2, and two side plates 13.3 connecting the top plate 13.1 and the bottom plate 13.2; multiple through holes 13.4 are distributed on the side plates 13.3; the distance between the connection between the two side plates 13.3 and the bottom plate 13.2 is greater than the width of the top plate 13.1 and less than the width of the bottom plate 13.2. The cross-sectional shape formed by the two side plates 13.3 and the top plate 13.1 is an isosceles trapezoid or a right trapezoid. The steel beam 13 located at the edge of the steel-concrete composite floor slab 2 adopts a right trapezoidal structure, and the steel beam 13 located in the middle of the steel-concrete composite floor slab 2 adopts an isosceles trapezoidal structure, such as... Figure 6 As shown. Figure 6The diagram shows two types of steel beams 13 with different cross-sectional shapes, as well as the dimensional parameters of two types of concealed beams, in mm. Furthermore, the internal space of the steel beam 13 is equipped with multiple fire-resistant reinforcing bars 13.5, for example, two fire-resistant reinforcing bars 13.5, arranged along the length of the steel beam. This eliminates the need for secondary fireproofing treatment of the concealed beam base plate. By employing a concealed beam structure, the nominal plate thickness can be significantly reduced while ensuring sufficient load-bearing capacity.

[0048] From the perspective of a young homebuyer, this article interprets a dynamic progression of life scenarios and living spaces within a residential building, from starting a business at home to family growth, home-based elder care, and warm companionship. It shifts the concept of housing from "three homes for a lifetime" to "one home for a lifetime." (See also...) Figure 8 .

[0049] Compared with existing technologies, the full-lifecycle variable interior space building system provided in this embodiment can achieve the following beneficial effects: 1. This utility model building system adapts to the variable living requirements of different family structures and different living scenarios, and can realize the global variability of living space, water space and balcony space throughout the entire life cycle of the family and residence.

[0050] 2. The interior employs a concealed beam design and a lowered slab treatment. Water supply spaces and horizontal pipes are centrally located within the lowered slab area, and equipment is integrated into the nominal slab thickness. This ensures that at most one supporting column is visible indoors, thereby creating a large space with a clear height of up to 2700mm within a building floor height of 3100mm. The clear height in the kitchen and bathroom areas can exceed 2400mm, ensuring functionality while enhancing spatial freedom. This utility model building system allows for free arrangement of interior space according to living needs, supporting flexible and adaptable housing throughout its entire life cycle.

[0051] 3. Through the interconnected design of the residential “backyard”, equipment platform and “front yard”, the operation and maintenance of facilities and equipment and the upgrading and renovation of shared facilities do not need to go through “personal space”, so that maintenance and repair do not affect residents’ lives and equipment and facilities maintenance do not enter the house, realizing the sustainable renewal and long-term use value of the building.

[0052] 4. By centrally arranging shared vertical pipelines for sewage, rainwater, and gas on the outside of the building envelope, a complete separation of "shared facilities" and "personal space" is achieved, significantly reducing the impact of maintenance and upgrades of shared facilities on residential life and enabling sustainable renewal. Furthermore, no vertical pipes penetrate the floor slabs within the living space, eliminating the risk of leakage at the pipe roots.

[0053] 5. Measures such as separating elevator shafts from living spaces, placing equipment platform areas adjacent to toilets, and externally placing rainwater and drainage risers, horizontal drainage in toilets on the same floor, and horizontal direct discharge of kitchen and bathroom fumes are adopted to reduce noise sources.

[0054] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this application. It should be understood that the above description is only a specific embodiment of this application and is not intended to limit the scope of protection of this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
