Description

Technical Field

[0001] This invention relates to the field of prefabricated buildings, and in particular to a reinforced core-filled concrete building module, system, production method and application thereof. Background Technology

[0002] Modular Integrated Construction (MIC) breaks down buildings into individual three-dimensional spatial modules (such as a complete bedroom or a suite with a bathroom). Before leaving the factory, the structure, insulation, water and electricity pipelines, interior decoration, and even furniture and appliances are already installed in place. On-site installation only requires hoisting and pipeline connection. This is similar to manufacturing cars, treating buildings as industrial products for production.

[0003] The development of MIC (Industrialized Construction) was not achieved overnight; it evolved alongside the deepening of policies on industrialized construction.

[0007] However, there are still many challenges in the application of the MIC system, such as transportation costs: the initial construction cost is relatively high, and the transportation of ultra-large modules poses a huge challenge to urban roads, requiring the use of special tower cranes for hoisting. Production costs: traditional concrete MICs rely on customized steel molds, which are costly (mold costs account for 25-30%), and are only suitable for standardized housing types, making it difficult to adapt to the differentiated needs of affordable housing, apartments, etc.

[0008] Therefore, how to learn from the architectural concepts of MIC to promote lightweight and modular construction is a problem that this invention urgently needs to solve. For this reason, this invention was born.

[0009] It should be noted that the information disclosed in the background section of this invention is intended only to enhance the understanding of the general background of this invention, and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0013] Preferably, the third tongue and groove joint of the base plate and the fourth tongue and groove joint of the top plate are provided with overlapping members.

[0014] Preferably, the overlapping members between the bottom plates in adjacent modules are implemented as bottom plate overlapping loops, and the bottom plate overlapping loops of adjacent bottom plates overlap each other and are anchored to the structural core column; the overlapping members between the top plates in adjacent modules are implemented as top plate overlapping loops, and the top plate overlapping loops of adjacent top plates overlap each other and are anchored to the structural core column.

[0015] Preferably, the top plate is provided with a top plate connecting bar, which is exposed at the end of the top plate and extends downward to form a top plate insertion section. The top plate insertion section is inserted into the first pairing hole of the block wall and anchored to the core column of the wall.

[0016] Preferably, the base plate is provided with a base plate connecting bar, the base plate connecting bar is exposed at the end of the base plate and extends upward to form a base plate insertion section, the base plate insertion section is inserted into the first pairing hole of the masonry wall and anchored to the core column of the wall.

[0017] The present invention also provides a reinforced core-filled concrete block building system, comprising at least two parallel reinforced core-filled concrete block building modules; the second pair of joint holes formed by the second pair of joints of the block walls of the adjacent modules, wherein a steel cage structure is provided in the second pair of joint holes and is cast to form a structural core column.

[0018] Preferably, it also includes two stacked reinforced core-filled concrete building modules; the second tongue-and-groove positions of the block walls of adjacent stacked modules correspond along the height direction.

[0019] This invention also provides a method for producing a reinforced core-filled concrete block building system, comprising the following steps: Prefabrication stage: Prefabricate reinforced concrete block building modules, each module including a top slab, a bottom slab, and block walls; stack the blocks on the bottom slab in a staggered manner to form the block walls; pour the main holes and the first pair of holes in the staggered joints of the blocks in the upper and lower layers of the block walls to form the wall core columns; and fix the top slab to the block walls to form the module. Lifting stage: The modules are lifted to the construction site in sequence. The second pair of tongue and groove joints of the masonry block walls of adjacent modules are tightly joined to form the second pair of holes. A steel cage structure is installed in the second pair of holes. Cast-in-place stage: The second pair of holes are poured through the entire height to form the structural core column.

[0020] Preferably, overlapping members are provided at the third tongue and groove joint of the base plate and the fourth tongue and groove joint of the top plate.

[0021] Preferably, the overlapping members between the bottom plates in adjacent modules are implemented as bottom plate overlapping loops, and the bottom plate overlapping loops of adjacent bottom plates overlap each other and are anchored to the structural core column; the overlapping members between the top plates in adjacent modules are implemented as top plate overlapping loops, and the top plate overlapping loops of adjacent top plates overlap each other and are anchored to the structural core column.

During the prefabrication stage, the top plate insertion section and the bottom plate insertion section are inserted into the first pairing holes of the masonry wall and anchored to the wall core column.

[0023] The present invention also provides an application of a reinforced core-filled concrete block building system, wherein the reinforced core-filled concrete block building system is used in a formwork-free application within the MIC building system.

[0024] The present invention, employing the above technical solution, achieves at least one of the following beneficial effects: This application uses blocks to form block walls, which are then connected to the top and bottom slabs to form standard modules. The hollow structure of the blocks makes the overall structure lightweight, eliminating the need for special tower cranes for hoisting. Moreover, the modules do not require special steel molds like traditional MIC modules, greatly reducing costs and increasing versatility.

[0025] By using standard blocks instead of integral steel molds, the cost of custom molds, which accounts for 25%-30% of the cost of traditional concrete MICs, is completely eliminated. At the same time, the weight of the modules is greatly reduced due to the hollow blocks, significantly reducing the reliance on and cost of special transportation and hoisting equipment, making MIC technology more universally applicable in terms of economy.

[0026] The walls are flexibly constructed using blocks, breaking the strict limitations of traditional steel molds on apartment design. This allows for quick and low-cost adaptation to non-standard and diverse architectural design needs, resolving the contradiction between standardized production and personalized requirements.

[0027] Its lightweight and mold-free characteristics make this technology widely applicable to cost-sensitive and variable housing projects such as affordable housing, apartments, schools, and hospitals, as well as to areas where traditional heavy-duty modular construction (MIC) is difficult to apply, such as building renovation and emergency construction, thus promoting the large-scale development of modular buildings.

[0043] The preferred embodiments described below are merely examples, and other obvious variations will be apparent to those skilled in the art. The basic principles of the invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

[0044] Example 1: Please see Figures 1-14This embodiment describes a reinforced concrete block building module, including a block wall 1, a base slab 2, and a top slab 3. The block wall 1 comprises multiple stacked blocks 11. Each block 11 includes a central main body 111 and symmetrically arranged interlocking portions 112 on both sides of the central main body 111. The central main body 111 has a main body opening 1110. The end of the interlocking portion 112 forms a first interlocking tongue-and-groove joint to form a first interlocking opening 1120 with adjacent blocks 11. The outer side of the side of the interlocking portion 112 forms a second interlocking tongue-and-groove joint 113 to form a second interlocking opening 1130 with the block wall 1 of the adjacent module. The upper and lower layers of blocks 11 are staggered and filled with the main body opening 1110 and the first interlocking opening 1120 to form a wall core column 114. A reinforcing cage structure 4 is installed within the second interlocking opening 1130 formed by the block wall 1 of the adjacent module and is cast to form a structural core column 12. The base plate 2 is fixedly supported on the bottom of the block wall 1. The end of the base plate 2 forms a third joint groove 20 that mates with the base plate 2 of the adjacent module to form a third joint hole; the third joint hole is connected to the second joint hole 1130 for grouting. The top plate 3 is fixedly laid on the top of the block wall 1. The end of the top plate 3 forms a fourth joint groove 30 that mates with the top plate 3 of the adjacent module to form a fourth joint hole; the fourth joint hole is connected to the second joint hole 1130 for grouting.

[0045] Please combine Figure 12 and Figure 13 In this embodiment, the block 11 is a wall building component. After being stacked in a staggered manner, the main hole 1110 and the first pairing hole 1120 of the block wall 1 are poured to form the wall core column 114.

[0046] The staggered stacking results in a sawtooth-like appearance on the side of the wall, which can be smoothed by cutting. As a preferred implementation of this embodiment, the blocks 11 are symmetrically separated into supplementary blocks 11a at the initial design stage. During stacking, the supplementary blocks 11a are used to supplement the side and form a smooth wall edge.

[0047] For details, please refer to Figure 12 The block 11 includes a central body 111 and symmetrically arranged interlocking portions 112 on both sides of the central body 111. In a preferred embodiment, the central body 111 is a rectangular column with a through-hole 1110 inside. The interlocking portion 112 includes a straight section and a U-shaped section. One end of the straight section is connected to the rectangular column, and the other end is connected to the U-shaped section. The opening of the U-shaped section is implemented as a first interlocking tongue-and-groove joint. Because the upper and lower layers of blocks 11 are stacked in a staggered manner, the dimensions of the structure after the two U-shaped sections are interlocked are optimally equal to the rectangular column. It should be noted that the block 11 is a type of molded brick, with the central body 111 and the interlocking portions 112 integrally formed.

[0048] As is common knowledge regarding block 11, the bottom and top of block 11 are provided with interlocking grooves for easy installation, which will not be elaborated upon here. Furthermore, structural reinforcing bars can be arranged in the first pairing holes 1120 and the main holes of the block wall 1, and then poured to form a structure like... Figure 4 The wall core column 114 shown; the wall core column 114, together with the staggered joint grouting method of the masonry block 11, makes the masonry block wall 1 form a whole.

[0049] Furthermore, the top plate 3 and bottom plate 2 of the module serve as inter-floor slabs in the assembled building, forming a complete building module by connecting with the block wall 1. Specifically, as shown... Figure 2 As shown, the top slab 3 is provided with a top slab connecting rib 31. The top slab connecting rib 31 is exposed at the end of the top slab 3 and extends downward to form a top slab insertion section. The top slab insertion section is inserted into the first splicing hole 1120 or the main hole 1110 of the masonry wall 1 (depending on the staggered stacking position of the masonry wall 1) and anchored to the wall core column 114. Similarly, the bottom slab 2 is provided with a bottom slab connecting rib 21. The bottom slab connecting rib 21 is exposed at the end of the bottom slab 2 and extends upward to form a bottom slab insertion section. The bottom slab insertion section is inserted into the first splicing hole 1120 or the main hole 1110 of the masonry wall 1 (depending on the staggered stacking position of the masonry wall 1) and anchored to the wall core column 114. Furthermore, the number and position of the top slab connecting rib 31 and the bottom slab connecting rib 21 correspond to the wall core column 114 of the masonry wall 1.

[0050] Therefore, the modules can be prefabricated in the factory, facilitating on-site installation and realizing the MIC (Mixed Instructions for Building) concept. However, the top slab 3 and bottom slab 2 can be formed using ordinary molds; the block wall 1 is constructed by stacking blocks and then casting a core to fix them into a complete wall panel. Compared to existing MIC building modules, no special steel molds are required, and the module design is more flexible, allowing for a wider variety of architectural styles.

[0051] Furthermore, in order for the floor slabs of adjacent modules to form a whole (top slab 3 and bottom slab 2), as a preferred embodiment of this example, please refer to... Figure 2 , Figure 5 and Figure 6 The third tongue-and-groove joint 20 of the base plate 2 and the fourth tongue-and-groove joint 30 of the top plate 3 are provided with overlapping members. Further, the overlapping members are overlapping slings. The overlapping members between the base plates 2 in adjacent modules are implemented as base plate overlapping slings 22, with the base plate overlapping slings 22 of adjacent base plates 2 overlapping each other and anchored to the structural core column 12; the overlapping members between the top plates 3 in adjacent modules are implemented as top plate overlapping slings 32, with the top plate overlapping slings 32 of adjacent top plates 3 overlapping each other and anchored to the structural core column 12.

[0052] Furthermore, the third and fourth tongue-and-groove joints 20 and 30 are spaced along the edge of the block, creating a serrated edge. This serrated structure matches the top and bottom shapes of the block wall 1, forming a standardized structure. Specifically, the dimensional parameters of the third and fourth tongue-and-groove joints 20 and 30 are the same as those of the second tongue-and-groove joint 113 of the block 11, and they are subsequently cast to full height to form a structural core column 12, anchoring the lap joints of the top plate 3 and bottom plate 2 within it. Subsequently, the lap joints of the top plate 3 and bottom plate 2 of adjacent modules are effectively overlapped and then anchored to the structural core column 12.

[0053] It should be noted that the module in this embodiment is not limited to the cube shown in the attached figure. The design flexibility of its block wall 1, combined with the insertion and anchoring of the bottom plate and the top plate, can realize a variety of structural forms.

[0054] Example 2: Please combine Figures 1-14 This embodiment provides a reinforced core-filled concrete block building system, which includes at least two parallel reinforced core-filled concrete block building modules of Embodiment 1. Specifically, the second joint tongue and groove 113 of the adjacent module block wall 1 forms a second joint hole 1130, and a steel cage structure 4 is provided in the second joint hole 1130 and is cast to form a structural core column 12.

[0055] As above, please refer to Figures 5-8 When the building system is a single-story structure, multiple reinforced concrete block building modules are arranged side by side. The second pair of tongue-and-groove joints 113 between adjacent modules forms the casting space for the structural column, and the positions of the third pair of tongue-and-groove joints 20 of the bottom slab 2 and the fourth pair of tongue-and-groove joints 30 of the top slab 3 in each module correspond to this casting space. Alternatively, the third pair of tongue-and-groove joints 20 of the bottom slab 2 in adjacent modules are closely fitted to form a third pair of holes, and the fourth pair of tongue-and-groove joints 30 of the bottom slab 2 in adjacent modules are closely fitted to form a fourth pair of holes. The second pair of holes 1130, the third pair of holes, and the fourth pair of holes are cast to full height to form the structural core column 12.

[0056] Furthermore, this system extends to multi-layered structures. As an implementation method in this first embodiment, such as... Figure 9 and Figure 10 As shown, this system also includes two or more stacked reinforced concrete block building modules. Furthermore, the second joint 113 positions of the adjacent stacked module block wall 1 correspond along the entire height. In view of the above, the second joint holes 1130, third joint holes, and fourth joint holes of the adjacent stacked modules are cast to form structural core columns 12.

[0057] Through the aforementioned multi-layered and multi-row design, various architectural requirements can be met by repeated stacking. After stacking, multiple modules are connected longitudinally and transversely by structural core columns 12 to form a building system.

[0058] Example 3: This embodiment describes a production method for a reinforced core-filled concrete block building system, including the following steps: S1 Prefabrication Stage: Specifically, the precast reinforced concrete block building module includes a top slab 3, a bottom slab 2, and a block wall 1. The blocks 11 are stacked on the bottom slab 2 in a staggered manner to form the block wall 1. The blocks 11 in the upper and lower layers of the block wall 1 are poured with the main holes 1110 and the first pairing holes 1120 in a staggered manner to form the wall core column 114. The top slab 3 is then fixedly laid on the block wall 1 to form the module.

[0059] In this embodiment, the block 11 is a wall building component. After being stacked in a staggered manner, the main hole 1110 and the first pairing hole 1120 of the block wall 1 are poured to form the wall core column 114.

[0060] Specifically, the block 11 includes a central body 111 and symmetrically arranged interlocking portions 112 on both sides of the central body 111. In a preferred embodiment, the central body 111 is a rectangular column with a through-hole 1110 inside. The interlocking portion 112 includes a straight section and a U-shaped section. One end of the straight section is connected to the rectangular column, and the other end is connected to the U-shaped section. The opening of the U-shaped section is implemented as a first interlocking tongue-and-groove joint. Because the upper and lower layers of blocks 11 are stacked in a staggered manner, the dimensions of the structure after the two U-shaped sections are interlocked are optimally equal to the rectangular column. It should be noted that the block 11 is a type of molded brick, with the central body 111 and the interlocking portions 112 integrally formed.

[0061] As is common knowledge regarding the use of block 11, the bottom and top of block 11 are provided with grooves for easy installation, which will not be elaborated here. Furthermore, structural steel bars can be arranged in the first pairing holes 1120 and the main holes of the block wall 1, and then poured to form the wall core column 114; the wall core column 114, in conjunction with the staggered pouring method of the block 11, makes the block wall 1 a whole.

[0062] Furthermore, the top plate 3 and bottom plate 2 of the module serve as inter-floor slabs in the assembled building. They connect with the block wall 1, thus forming a complete building module with the block wall 1. Specifically, the top plate 3 is provided with a top plate connecting bar 31, which is exposed at the end of the top plate 3 and extends downward to form a top plate insertion section. The top plate insertion section is inserted into the first pairing hole 1120 or the main hole 1110 of the block wall 1 (depending on the staggered stacking position of the block wall 1) and anchored to the wall core column 114. Similarly, the bottom plate 2 is provided with a bottom plate connecting bar 21, which is exposed at the end of the bottom plate 2 and extends upward to form a bottom plate insertion section. The bottom plate insertion section is inserted into the first pairing hole 1120 or the main hole 1110 of the block wall 1 (depending on the staggered stacking position of the block wall 1) and anchored to the wall core column 114. Furthermore, the number and position of the top slab connecting bar 31 and the bottom slab connecting bar 21 correspond to the wall core column 114 of the block wall 1.

[0063] Therefore, the modules can be prefabricated in the factory, facilitating on-site installation and realizing the MIC (Mixed Instructions for Building) concept. However, the top slab 3 and bottom slab 2 can be formed using ordinary molds; the block wall 1 is constructed by stacking blocks and then casting a core to fix them into a complete wall panel. Compared to existing MIC building modules, no special steel molds are required, and the module design is more flexible, allowing for a wider variety of architectural styles.

[0064] Furthermore, to ensure that the floor slabs of adjacent modules form a whole (top slab 3 and bottom slab 2), in a preferred embodiment of this example, the third tongue-and-groove joint 20 of the bottom slab 2 and the fourth tongue-and-groove joint 30 of the top slab 3 are provided with overlapping members. Further, the overlapping members are overlapping slings. The overlapping members between bottom slabs 2 in adjacent modules are implemented as bottom slab overlapping slings 22, with the bottom slab overlapping slings 22 of adjacent bottom slabs 2 overlapping each other and anchored to the structural core column 12; the overlapping members between top slabs 3 in adjacent modules are implemented as top slab overlapping slings 32, with the top slab overlapping slings 32 of adjacent top slabs 3 overlapping each other and anchored to the structural core column 12.

[0065] Furthermore, the third and fourth tongue-and-groove joints 20 and 30 are spaced along the edge of the board, creating a serrated edge. This serrated structure matches the top and bottom shapes of the block wall 1, forming a standardized structure. Specifically, the dimensional parameters of the third and fourth tongue-and-groove joints 20 and 30 are the same as those of the second tongue-and-groove joint 113 of the block 11, and they are subsequently cast to full height to form a structural core column 12, anchoring the connecting cables of the top plate 3 and the bottom plate 2 within it. Subsequently, the connecting cables of the top plate 3 and the bottom plate 2 of adjacent modules effectively overlap and are anchored to the structural core column 12.

[0066] S2 hoisting phase: Specifically, the modules are hoisted to the construction site in sequence, and the second pair of tongue and groove joints 113 of the adjacent module block wall 1 are closely spliced ​​to form the second pair of holes 1130, and a steel cage structure 4 is installed in the second pair of holes 1130.

[0067] When the building system is a single-story structure, multiple reinforced concrete block building modules are arranged side by side. The second pair of tongue-and-groove joints 113 between adjacent modules forms the casting space for the structural column, and the positions of the third pair of tongue-and-groove joints 20 of the bottom slab 2 and the fourth pair of tongue-and-groove joints 30 of the top slab 3 in each module correspond to this casting space. Alternatively, the third pair of tongue-and-groove joints 20 of the bottom slab 2 in adjacent modules are closely fitted to form a third pair of holes, and the fourth pair of tongue-and-groove joints 30 of the bottom slab 2 in adjacent modules are closely fitted to form a fourth pair of holes. The second pair of holes 1130, the third pair of holes, and the fourth pair of holes are cast to full height to form the structural core column 12.

[0068] Furthermore, this system extends to multi-layer structures. As one embodiment of this invention, the system also includes two or more stacked reinforced concrete block building modules. Furthermore, the second joint 113 positions of the adjacent stacked module block walls 1 correspond along the entire height. In view of the above, the second joint holes 1130, third joint holes, and fourth joint holes of the adjacent stacked modules are cast to form structural core columns 12.

[0069] Through the aforementioned multi-layered and multi-row design, various architectural requirements can be met by repeated stacking. After stacking, multiple modules are connected longitudinally and transversely by structural core columns 12 to form a building system.

[0070] S3 Cast-in-place stage: Specifically, the second pair of holes 1130 are poured to form the structural core column 12.

[0071] Example 4: This embodiment describes the application of a reinforced core-filled concrete block building system, specifically its formwork-free application within the MIC (Made in China) building system. The structure of this reinforced core-filled concrete block building system is described in Embodiment 2 and will not be repeated here.

[0072] This embodiment is based on the concept of MIC architecture, but it does not require the large steel formwork of traditional MIC architecture. Instead, the modules are assembled using a top plate 3, a bottom plate 2, and block walls 1. The hollow structure of the blocks 11 enables the overall lightweight design, and the top plate 3, bottom plate 2, and block walls 1 are not limited to steel formwork but can be flexibly designed and adjusted.

[0073] Furthermore, the present invention has been described in detail above with reference to the accompanying drawings and embodiments. Those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention shall be defined by the appended claims.
