Description

Technical Field

[0001] This application belongs to the technical field of modular prefabricated buildings and post-cast shear walls. More specifically, it relates to a concrete module building installation method, an interlocking connection structure, and a method for determining its quantity. Background Art

[0002] Modular Integrated Construction (MiC) is the highest level of integration and industrialization in prefabricated buildings and represents the highest form of current prefabricated buildings. Different from prefabricated buildings using precast components, Modular Integrated Construction does not use basic components such as beams, slabs, and columns as units. Instead, during the scheme or construction drawing design stage, the building is divided based on building functions, and each functional unit is split into multiple spatial unit modules. In a factory or production line, multiple components and parts are combined into a complete module, and then multiple modules are transported to the site for assembly into a complete building, which is a new type of green construction method. It maximally moves the building from the construction site to the factory, truly realizing the concept of "building houses like making cars".

[0003] The concrete MiC hexahedron module product has the characteristics of high integration and can integrate architecture, mechanical and electrical systems, interior decoration, etc. Concrete MiC can achieve the integration of water and electricity pipelines and the integration of decoration. Pipeline embedding in the module only requires on-site assembly. At the same time, the interior decoration of the room can be completed in the factory, which is conducive to cost control, material saving, and quality improvement.

[0004] When two modules are spliced on the construction site, a concrete thin shell needs to be used as a concrete formwork and poured on the construction site to form a shear wall. In related technologies, when two modules are spliced on the construction site, a tie rod is used to penetrate the two concrete thin shells, which damages the concrete thin shells and requires later repair, reducing the integration degree of the prefabricated building.

[0005] Therefore, it is urgent to study a concrete module building installation method for splicing two concrete thin shells. Summary of the Invention

[0063] Modular Integrated Construction (MiC) is the highest level of integration and industrialization in prefabricated buildings and represents the highest form of prefabricated buildings currently. Different from prefabricated buildings using precast components, Modular Integrated Construction does not use basic components such as beams, slabs, and columns as units. Instead, during the scheme or construction drawing design stage, the building is divided based on building functions, and each functional unit is split into multiple spatial unit modules. In a factory or on a production line, multiple components and parts are combined into a complete module, and then multiple modules are transported to the site for assembly into a complete building, which is a new type of green construction method. It maximally moves the building from the construction site to the factory, truly realizing the concept of "building houses like manufacturing cars".

[0064] Concrete MiC hexahedron module products have the characteristics of high integration and can integrate architecture, mechanical and electrical systems, interior decoration, etc. Concrete MiC can achieve the integration of water and electricity pipelines and interior decoration. Pipeline embedding can be done in the module, and only on-site assembly is required. At the same time, the interior decoration of the room can be completed in the factory, which is beneficial to cost control, material saving, and quality improvement.

[0065] Please refer to Figure 1, when the two modules are spliced on the construction site, it is necessary to use the concrete thin shell as the concrete formwork and pour the post-cast shear wall on the construction site. In the related art, when the two modules are spliced on the construction site, the tie bolts 30 penetrate through the two concrete thin shells, causing damage to the concrete thin shells, which requires later repair and reduces the integration degree of the prefabricated building. It can be understood that the two concrete thin shells can be divided into the first concrete thin shell 10 and the second concrete thin shell 20.

[0066] Please refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 , to solve the above technical problems, the embodiment of the present application proposes an interlocking connection structure for a concrete module building. The concrete module building includes two precast concrete thin shells and a steel reinforcement cage 3 located between the two precast concrete thin shells. The interlocking connection structure includes a first embedded part 1 and a second embedded part 2. The first embedded part 1 includes a first end 11 and a second end 12. The first end 11 of the first embedded part 1 is located inside the side wall of one of the two adjacent precast concrete thin shells (the first concrete thin shell 10). The second embedded part 2 includes a third end 21 and a fourth end 22. The third end 21 of the second embedded part 2 is located inside the side wall of the other of the two adjacent precast concrete thin shells (the second concrete thin shell 20).

[0068] Optionally, the interlocking connection structure proposed by the embodiment of the present application further includes an interlocking connector 4. The second end 12 of the first embedded part 1 and the fourth end 22 of the second embedded part 2 are located inside the steel reinforcement cage 3. The interlocking connector 4 is located inside the steel reinforcement cage 3, and the interlocking connector 4 connects the second end 12 of the first embedded part 1 and the fourth end 22 of the second embedded part 2.

[0069] It can be understood that the interlocking connection structure proposed by the embodiment of the present application can also extend the second end 12 of the first embedded part 1 and the fourth end 22 of the second embedded part 2 into the steel reinforcement cage 3, and then use the interlocking connector 4 to connect the second end 12 of the first embedded part 1 and the fourth end 22 of the second embedded part 2, which is beneficial to improving the structural strength of the concrete module building.

[0070] Please refer to Figure 3 , Figure 4 and Figure 5, in some embodiments, the first embedded part 1 is of a U-shaped structure. The two ends of the first embedded part 1 are the first ends 11, and the root of the first embedded part 1 is the second end 12. It can be understood that the two ends of the first embedded part 1 are provided with bending parts, and the bending part of one end bends in a direction away from the other end.

[0071] Optionally, the two ends of the first embedded part 1 are arranged along the length direction of the steel reinforcement cage 3 (such as Figure 5 the Y direction in

[0072] ), or the two ends of the first embedded part 1 are arranged at intervals along the height direction of the steel reinforcement cage 3.

[0073] Optionally, the second embedded part 2 is of a U-shaped structure. The two ends of the second embedded part 2 are the third ends 21, and the root of the second embedded part 2 is the fourth end 22. Similarly, the two ends of the second embedded part 2 are also provided with bending parts, and the bending part of one end bends in a direction away from the other end. Figure 5 Optionally, the two ends of the second embedded part 2 are arranged along the length direction of the steel reinforcement cage 3 (such as

[0074] the Y direction in Figure 3 ), or the two ends of the second embedded part 2 are arranged at intervals along the height direction of the steel reinforcement cage 3. Figure 4 and Figure 5 , in some embodiments, there are multiple first embedded parts 1. The multiple first embedded parts 1 are arranged at intervals along the height direction of the steel reinforcement cage 3 (such as Figure 3 the X direction in

[0075] ). There are multiple second embedded parts 2. The multiple second embedded parts 2 are arranged at intervals along the height direction of the steel reinforcement cage 3. The interlocking connector 4 includes multiple first connectors 41. One first connector 41 connects one first embedded part 1 and one second embedded part 2. That is, the first connectors 41 correspond one by one to the first embedded parts 1, and the first embedded parts 1 and the second embedded parts 2 also correspond one by one. Figure 5 Optionally, referring to Figure 5 , the multiple first embedded parts 1 and the multiple second embedded parts 2 are also arranged at intervals along the length direction of the steel reinforcement cage 3 (such as

[0076] the Y direction in

[0077] ). That is, the multiple first embedded parts 1 can be arranged in an array on the surface of the first concrete thin shell 10 facing the second concrete thin shell 20, and the multiple second embedded parts 2 can be arranged in an array on the surface of the second concrete thin shell 20 facing the first concrete thin shell 10.

[0076] Optionally, the multiple first embedded parts 1 are spaced 450 mm - 500 mm apart in the height direction of the steel reinforcement cage 3, and the multiple first embedded parts 1 are spaced 450 mm - 500 mm apart in the length direction of the steel reinforcement cage 3.

[0077] Optionally, multiple second embedded parts 2 are spaced 450 mm - 500 mm in the height direction of the steel reinforcement cage 3, and multiple second embedded parts 2 are spaced 450 mm - 500 mm in the length direction of the steel reinforcement cage 3.

[0078] It can be understood that the first embedded part 1 and the second embedded part 2 are U-shaped structures, which facilitate the connection between the first connecting member 41 and the first embedded part 1 and the second embedded part 2, and can improve the connection stability, thus being beneficial to improving the stability of the concrete module structure.

[0079] Optionally, the first connecting member 41 is welded to the first embedded part 1 and the second embedded part 2.

[0080] Please refer to Figure 3 、 Figure 4 and Figure 5 , in some embodiments, the interlocking connecting member 4 further includes a second connecting member 42, and the second connecting member 42 is connected to multiple first connecting members 41. The second connecting member 42 can connect multiple first connecting members 41 together, can improve the stability of the first connecting members 41, and thus is beneficial to improving the stability of the concrete module structure.

[0081] In some embodiments, the first connecting member 41 is a U-shaped structure, and the two end portions of the first connecting member 41 are respectively connected to the first embedded part 1 and the second embedded part 2.

[0082] Optionally, please refer to Figure 3 , the two end portions of the first connecting member 41 are located below the root. That is, the first connecting member 41 can be inserted into the first embedded part 1 and the second embedded part 2 from top to bottom.

[0083] Optionally, please refer to Figure 4 , the two end portions of the first connecting member 41 are located above the root. That is, the first connecting member 41 can be inserted into the first embedded part 1 and the second embedded part 2 from top to bottom. In this way, the first embedded part 1 and the second embedded part 2 can limit the first connecting member 41, and can prevent the first connecting member 41 from floating due to the buoyancy generated during concrete pouring.

[0084] It can be understood that the first connecting member 41 is also a U-shaped structure, which can facilitate the connection with the first embedded part 1 and the second embedded part 2.

[0085] Among them, the two end portions of the first connecting member 41 are respectively connected to the first embedded part 1 and the second embedded part 2, and the root of the first connecting member 41 is connected to the second connecting member 42.

[0086] Optionally, the root of the first connecting member 41 is welded to the second connecting member 42.

[0087] Optionally, the second connecting member 42 is a rod-shaped or bar-shaped structure.

[0088] It is understandable that the first connecting member 41 and the second connecting member 42 are connected to form an interlocking connecting member 4, and the interlocking connecting member 4 can be a multi-stage bar hook connector 4 (Bar Hook Connector).

[0097] It is understandable that the installation method proposed in the embodiment of the present application can first connect the second end 12 of the first embedded part 1 and the fourth end 22 of the second embedded part 2 by using the first connecting member 41, and then connect a plurality of first connecting members 41 adjacent in the height direction of the steel reinforcement cage 3 by using the second connecting member 42.

[0098] Optionally, when connecting the second end 12 of the first embedded part 1 to the fourth end 22 of the second embedded part 2 using the first connecting member 41, the first connecting member 41 can be inserted into the first embedded part 1 and the second embedded part 2 from top to bottom, or the first connecting member 41 can be inserted into the first embedded part 1 and the second embedded part 2 from bottom to top.

[0099] The installation method proposed in the embodiments of the present application can install the above-mentioned concrete module building, and has the same or similar technical effects as the interlocking connection structures in any of the above embodiments, which will not be elaborated here.

In the case of the first position, the second embedded part 2 is arranged at an interval from the steel reinforcement cage 3, that is, the fourth end 22 of the second embedded part 2 is arranged at an interval from the steel reinforcement cage 3. In the case of the second position, the second embedded part 2 extends into the steel reinforcement cage 3, and the fourth end 22 of the second embedded part 2 extends into the steel reinforcement cage 3.

[0103] It can be understood that each side wall of the steel reinforcement cage 3 is a mesh structure, that is, the side wall of the steel reinforcement cage 3 is provided with steel bars holes. The fourth end 22 of the second embedded part 2 can extend into the steel reinforcement cage 3 through the steel bars holes.

[0104] In this way, the manufacturing method of the concrete module proposed in the embodiments of the present application can connect two concrete thin shells (the first concrete thin shell 10 and the second concrete thin shell 20) and manufacture a concrete module.

[0105] It can be understood that after the concrete module proposed in the embodiments of the present application is manufactured, a casting cavity can be formed through an auxiliary formwork, and then concrete slurry can be poured into the steel reinforcement cage 3 to form a post-cast shear wall, so that the first concrete thin shell 10 and the second concrete thin shell 20 can be spliced on site.

[0106] Please refer to Figure 9 , Figure 10 and Figure 11 , the embodiments of the present application also propose a method for determining the number of the interlocking connection structures in the above embodiments.

[0112] S15. Calculate the quantity m of the interlocking connector structure according to the quantity n of the first connector 41.

[0113] It can be understood that the quantity determination method proposed in the embodiment of the present application can determine the quantity of the first connector 41 and the interlocking connector 4. According to the quantity of the interlocking connector 4, the quantity of the interlocking connection structure can be determined, and the concrete module building can be installed according to the quantity of the interlocking connection structure.

[0114] Among them, the first connector 41 can be arranged in m columns along the length direction of the steel reinforcement cage 3 according to the site conditions. The quantities of the first connectors 41 in different columns can be the same or different. Optionally, the second connector 42 is m, and one second connector 42 connects the first connectors 41 in one column together. In this way, the quantity of the interlocking connector 4 is also m, that is, the quantity of the interlocking connector 4 is the same as the quantity of the second connector 42 and can be obtained according to the quantity of the first connector 41.

[0115] It can be understood that the quantity n of the first connector 41 is calculated by the following formula:

[0116]

[0117] The following describes the specific calculation process of the quantity n of the first connector 41.

[0118] Please refer to Figure 9 and Figure 10 , when the concrete module is manufactured, the acting force of the poured concrete slurry on the first concrete thin shell 10 and the second concrete thin shell 20 in the liquid state is:

[0119]

[0120] Wherein, A is the area of the surface of the first concrete thin shell 10 facing the second concrete thin shell 20, or A is the area of the surface of the second concrete thin shell 20 facing the first concrete thin shell 10, and A = b * h.

[0121] The force on each first connecting member 41 is:
