Description

Technical Field

[0001] This invention relates to the field of impact load testing equipment, and more particularly to a concrete MiC structural system with an additional corridor. Background Technology

[0002] Prefabricated buildings refer to buildings where a large amount of on-site work in traditional construction methods is transferred to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in factories, transported to the construction site, and assembled and installed on-site using reliable connection methods.

[0003] Prefabricated buildings, due to their short construction cycle and minimal environmental impact, have become an important direction for achieving green building and industrialization. Among them, Modular Integrated Construction (MiC) is the prefabricated building type with the highest assembly rate and degree of industrialization. Currently, for regional buildings with small spans, prefabricated buildings mainly use prefabricated wood structures, prefabricated light steel structures, and precast concrete structures. Light steel prefabricated houses have advantages such as convenient transportation, disassembly, and high flexibility, but due to their light weight, high flexibility, low resistance, and high thermal conductivity, they have poor wind resistance, fire resistance, thermal insulation, and sound insulation capabilities. Prefabricated wood structures have good seismic performance and thermal insulation performance, but their fire resistance and corrosion resistance are poor, and their cost is high. Prefabricated buildings with precast concrete as the main structure also exist in existing technologies, but the construction efficiency of existing concrete prefabricated buildings is often low.

[0004] Therefore, there is an urgent need for a concrete MiC structural system for additional corridors with high construction efficiency. Summary of the Invention

[0008] To achieve the above objectives, the main technical solutions adopted by the present invention include:

[0009] This invention provides a concrete MiC (Military Concrete Structure) system with an attached corridor, comprising multiple hierarchical concrete modules connected sequentially from bottom to top. Each hierarchical concrete module includes multiple room concrete modules and precast corridor components. The room concrete modules are arranged horizontally, with adjacent room concrete modules connected by cast-in-place concrete. One end of each room concrete module forms a connection end, which is connected to one side of the precast corridor component. The room concrete modules at different vertical positions are connected by tie-rod type connection nodes.

[0010] Optionally, the prefabricated corridor components include prefabricated corridor beams, prefabricated corridor slabs, and at least two prefabricated corridor columns. The two prefabricated corridor columns are arranged vertically, and the prefabricated corridor beams are horizontally supported between them. The connecting end of the column is supported by the prefabricated corridor beams to form the main frame of the corridor. The prefabricated corridor slabs are laid at the bottom of the main frame of the corridor.

[0011] Optionally, the room concrete module includes a top beam, a bottom beam, and columns. At least four room module columns are arranged vertically, and the top and bottom beams are horizontally supported between adjacent room module columns to form the main frame of the room. The connection points between the vertically positioned room module columns are the connection points between the vertically positioned room concrete modules.

[0012] Optionally, the tie-rod type connection node includes a module connection plate, a column end plate, an enlarged aperture tube, a shear key, a screw sleeve, an inner steel pipe, and a connecting screw. The enlarged aperture tubes are respectively fixed to the top center and bottom center of the room module column, and the two enlarged aperture tubes at the connection points of the upper and lower room module columns are connected. The column end plate is laid on the top and bottom of the room module column, and the two column end plates at the connection points of the upper and lower room module columns are connected by the module connection plate. The inner steel pipe is fixed inside the room module column and connects the two enlarged aperture tubes at the top and bottom of the room module column. The screw sleeve is fixed inside the two connected enlarged aperture tubes, and both ends of the screw sleeve extend into the upper and lower inner steel pipes respectively. The shear key is arranged around the screw sleeve and fixed inside the enlarged aperture tube. The connecting screw passes through the inner steel pipe, and its two ends are respectively screwed into the two screw sleeves located at the upper and lower positions.

[0014] Optionally, the bottom beam of the upper-level room concrete module located at the connection end is connected to the corridor precast slab of the corridor precast component located on the same level by cast-in-place concrete, and is connected to the top beam of the lower-level room concrete module located at the connection end.

[0015] Optionally, the connection between the room formwork bottom beam and the corridor precast slab is provided with reserved reinforcing bars extending into the cast-in-place concrete area.

[0016] Optionally, the bottom beams of two adjacent room concrete modules are connected by cast-in-place concrete.

Detailed Implementation

[0028] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0029] like Figures 1-3 As shown, this invention provides a concrete MiC structure system with an attached corridor, comprising multiple hierarchical concrete modules connected sequentially from bottom to top. Each hierarchical concrete module includes multiple room concrete modules 1 and precast corridor components 2. The room concrete modules 1 are arranged horizontally, with adjacent room concrete modules 1 connected by cast-in-place concrete. One end of each room concrete module 1 forms a connection end, which is connected to one side of the precast corridor component 2. The connections between the upper and lower room concrete modules 1 are made using tie-rod type connection nodes, while the connections between the upper and lower precast corridor components 2 are made using conventional connection methods. The room concrete modules 1 have door and window openings for installing doors and windows. The door openings are located at the ends of the room concrete modules 1 forming the connection ends, and the door openings face the precast corridor component 2.

[0030] Specifically, in this structural system, both the room concrete modules 1 and the corridor prefabricated components 2 of the tiered concrete modules can be prefabricated in the factory and then transported to the construction site for assembly. Simply fixing the room concrete modules 1 to one side of the corridor prefabricated components 2 allows for the rapid and efficient formation of the entire floor's structure. Construction is quick, simple, and highly efficient. Furthermore, the formed building structure is reliable, structurally stable, and meets normal usage requirements. Compared to existing technologies, this structural system, while meeting normal usage requirements in terms of structural strength, can quickly form a multi-story building with numerous rooms through multiple tiered concrete modules. This significantly saves time for situations requiring rapid construction of temporary or even permanent buildings. It is suitable for buildings with high repetitive requirements, such as dormitories, hotels, classrooms, and hospital wards. It boasts advantages such as high standardization and flexible door and window opening arrangements, facilitating industrialized production and rapid construction.

[0031] Furthermore, such as Figure 1 As shown, the room concrete module 1 includes a room module top beam 11, a room module bottom beam 12, a room module column 13, a room module top slab 14, and a room module bottom slab 15. At least four room module columns 13 are arranged vertically, and the room module top beam 11 and room module bottom beam 12 are horizontally supported between adjacent room module columns 13 to form the main frame of the room. The connection points of the vertically positioned room module columns 13 are the connection points of the vertically positioned room concrete modules 1. The room module top slab 14 is laid on top of the main frame of the room, and the room module bottom slab 15 is laid on the bottom of the main frame of the room. The cross-sectional dimension of the room module top beam 11 is larger than that of the room module bottom beam 12. Specifically, the room module bottom beams 12 of adjacent room concrete modules 1 are connected by cast-in-place concrete. From a top view, the room concrete module 1 is rectangular in shape, with the four room module columns 13 arranged at the four corners of the rectangle. The two ends of the room module top beam 11 are respectively connected to the upper parts of two adjacent room module columns 13, and the four ends of the room module top plate 14 are respectively connected to four room module top beams 11. The tops of the room module columns 13, the tops of the room module top beams 11, and the tops of the room module top plate 14 are flush with each other. The two ends of the room module bottom beam 12 are respectively connected to the lower parts of two adjacent room module columns 13, and the four ends of the room module bottom plate 15 are respectively connected to four room module bottom plates 15. The top of the room module bottom plate 15 is flush with the top of the room module bottom beam 12.

[0032] Furthermore, such as Figure 1As shown, the prefabricated corridor component 2 includes a prefabricated corridor beam 21, a prefabricated corridor slab 22, and at least two prefabricated corridor columns 23. The two prefabricated corridor columns 23 are arranged vertically, and the prefabricated corridor beam 21 is horizontally supported between them. The connecting ends formed by the multiple room concrete modules 1 are also supported by the prefabricated corridor beam 21 between them, forming the main frame of the corridor. The prefabricated corridor slab 22 is laid at the bottom of the main frame of the corridor, forming the corridor floor. The connection points of the upper prefabricated corridor column 23, the prefabricated corridor beam 21, and the lower prefabricated corridor column 23 are the connection points of the upper and lower prefabricated corridor components 2, and the three are connected by a connection method specified in the prefabricated building atlas. Specifically, the height of the prefabricated corridor column 23 is flush with the height of the room concrete module 1. The two ends of the prefabricated corridor beam 21 located between the two prefabricated corridor columns 23 are respectively connected to the lower parts of the two prefabricated corridor columns 23, and the bottom of the prefabricated corridor beam 21 is flush with the bottom of the prefabricated corridor column 23. The two ends of the precast corridor beam 21, located between the precast corridor column 23 and the connecting end, are respectively connected to the lower parts of the precast corridor column 23 and the connecting end. The bottom of the precast corridor beam 21, the bottom of the precast corridor column 23, and the bottom of the room concrete module 1 are flush. One end of the precast corridor slab 22 is connected to the connecting end by cast-in-place concrete. Specifically, one end of the precast corridor slab 22 is connected to the bottom beam 12 of the room module located at the connecting end by cast-in-place concrete. The other three ends of the precast corridor slab 22 are connected to three precast corridor beams 21. The top of the precast corridor slab 22, the top of the precast corridor beams 21, the top of the room module bottom slab 15, and the top of the room module bottom beam 12 are flush. The main frame of the corridor at the top floor is also equipped with precast corridor beams 21 and precast corridor slabs 22, forming the corridor roof. The connection between the bottom beam 12 of the room module and the precast corridor slab 22 at the connecting end is provided with reserved steel bars 4 extending into the cast-in-place concrete area to improve the stability of the connection. The prefabricated corridor component 2 of this structural system will connect to the fire escape staircase. In the event of a fire, the corridor will be used as a fire escape route, which requires a higher load-bearing capacity. Therefore, the cross-sectional dimensions of the prefabricated corridor column 23 are larger than those of the room module column 13.

[0033] Furthermore, such as Figure 4As shown, the tie-rod type connection node includes a module connection plate 31, a column end plate 32, an enlarged aperture tube 33, a shear key 34, a threaded sleeve 35, an inner steel pipe 36, and a connecting screw 37. The enlarged aperture tube 33 is fixed to the top center and bottom center of the room module column 13, respectively. The two enlarged aperture tubes 33 at the connection point of the upper and lower room module columns 13 are connected. The column end plate 32 is laid on the top and bottom of the room module column 13. The column end plate 32 is provided with anchoring steel bars extending into the room module column 13. The two column end plates 32 at the connection point of the upper and lower room module columns 13 are connected by the module connection plate 31. The inner steel pipe 36 is fixed inside the room module column and the prefabricated corridor column, and the inner steel pipe 36 connects to two enlarged-diameter pipes 33 at the top and bottom of the room module column 13. The screw sleeve 35 is fixed inside the two connected enlarged-diameter pipes 33, and the two ends of the screw sleeve 35 extend into the inner steel pipe 36 at the upper and lower positions respectively. The shear key 34 is arranged around the screw sleeve 35 and fixed inside the enlarged-diameter pipes 33. The connecting screw 37 passes through the inner steel pipe 36, and its two ends are screwed to the two screw sleeves 35 at the upper and lower positions respectively. The room module column 13 at the bottom is fixed to the building foundation (not shown). The building foundation also has a screw sleeve 35 fixed on it, and the screw sleeve 35 extends into the inner steel pipe 36 from the enlarged-diameter pipe 33 at the bottom of the room module column 13. The connecting screw 37 inside the room module column 13 is screwed to the screw sleeve 35, and the column end plate 32 at its bottom is connected to the building foundation through the bottom fixing plate. The top-level room module column 13 has a top sealing plate on its top end plate 32 to seal the top end face. The top of the connecting screw 37 inside extends from the top and is tightened with a nut. During installation, the bottom-level room module column 13 is first fixed to the building foundation, and a module connecting plate 31 is laid on top of it. Then, the shear key 34 is fixed around the screw sleeve 35 inside the enlarged diameter pipe 33. The connecting screw 37 inside the upper-level room module column 13 is screwed into the screw sleeve 35. The two end plates 32 at the connection point of the upper and lower room module columns 13 are connected by the module connecting plate 31. This achieves a dry connection between the upper and lower module columns, eliminating the need for on-site concrete pouring, effectively reducing construction time. The joint is also detachable, recyclable, and the connection is reliable.

[0034] Furthermore, such as Figures 1-3As shown, the bottom beam 12 of the upper-level room concrete module 1 at the connection end is connected to the corridor precast slab 22 of the same-level corridor precast component 2 via cast-in-place concrete, and is also connected to the top beam 11 of the lower-level room concrete module 1 at the connection end. Specifically, the bottom beam 12 of the upper-level room concrete module 1 at the connection end is connected to the top slab 14 of the lower-level room concrete module 1 via a grouting layer. One end of the corridor precast slab 22 of the same-level corridor precast component 2 is connected to the top beam 11 of the lower-level room concrete module 1 at the connection end via a grouting layer. The cast-in-place concrete can connect the bottom beam 12 and the top beam 11 of the upper and lower-level room modules at the connection end, as well as the corridor precast slab 22 on the same level, into a whole, forming a T-shaped load-bearing component to enhance the overall structure.

[0035] The concrete MiC structural system for the additional corridor provided in this specific embodiment involves the following construction process: According to the architectural design purpose and requirements, prefabricated concrete modules for the house and various components of the corridor prefabricated components 2 are manufactured in a factory and transported to the construction site. First, multiple room concrete modules 1 are horizontally arranged and sequentially connected using cast-in-place concrete. Then, prefabricated corridor columns 23, prefabricated corridor beams 21, and prefabricated corridor slabs 22 are installed sequentially, thus forming multiple layers of concrete modules. Finally, according to the building's floors, the multiple layers of concrete modules are sequentially connected from bottom to top.
