AI Technical Summary
In existing technologies, the MIC structural system of high-rise buildings with large spaces requires a large amount of steel reinforcement during the splicing of modular units, resulting in weak integrity and seismic resistance. In addition, the amount of steel reinforcement for shear walls and the amount of formwork erection work in traditional high-rise MIC buildings are large, leading to high construction costs and poor overall integrity.
The system employs prefabricated pentahedral and tetrahedral modular units. Vertical and horizontal tongue-and-groove joints are used to install column and beam reinforcement bars at the connection points of the modular units to form a frame structure. Reinforcement grooves are provided at the splice joints and ground grooves for reinforcement connection, reducing the amount of on-site reinforcement binding and increasing the overall integrity and seismic resistance.
It reduces the amount of steel reinforcement tied in high-rise, large-space buildings, improves overall integrity and seismic resistance, reduces construction costs and on-site workload, and is suitable for large-space scenarios of any size.

DETAILED DESCRIPTION
[0027] The utility model will be described in further detail below in combination with the drawings and specific embodiments.

According to the design size of the high-rise large-space building, the number of single-layer structures and the height of each single-layer structure are determined. The MIC structure system of the embodiment shows a schematic view of splicing of one pentahedral module unit 1 and one tetrahedral module unit 2. Figure 1
[0029] The pentahedral module unit 1 includes a composite slab 6 at the top, a bottom plate at the bottom, two side plates and an end plate between the two side plates; the tetrahedral module unit 2 includes a composite slab at the top, a bottom plate at the bottom and two side plates.

[0031] The splicing joint of the superimposed plate of the pentahedron module unit 1 and the tetrahedron module unit 2 is provided with a reserved steel bar notch 5 for dividing the splicing joint; a steel bar is arranged in the reserved steel bar notch 5.
[0032] A surface layer steel bar is arranged on the superimposed plate of the pentahedron module unit 1 and the tetrahedron module unit 2.
[0033] The splicing joint of the bottom plate of the pentahedron module unit 1 and the tetrahedron module unit 2 is provided with a ground reserved notch 9; the embedded steel bar in the bottom plate of the pentahedron module unit 1 and the tetrahedron module unit 2 extends into the ground reserved notch 9 and is connected with the steel bar arranged in the ground reserved notch 9.
[0034] The pentahedron module unit and the tetrahedron module unit are both prefabricated in a factory. After the module units are produced and processed in the factory, they are transported to the construction site according to the construction progress, hoisted to the designated area, and then the column steel bars at the four corners of the module units are bound on site. The column steel bars should be bound or mechanically connected with the foundation reserved steel bars, and then the beam steel bars of the four sides are bound. The steel bars are placed in the multiple reserved steel bar notches of the superimposed plate, and the surface layer steel bars of the superimposed plate are bound. After all the steel bars are bound and the formwork is set, the concrete is poured on site, covering the steel bars in the reserved steel bar notches and the surface layer steel bars of the superimposed plate. The length and spacing of the reserved steel bar notches can be changed without reducing the bearing capacity, and the amount of steel used is reduced.

The inside work includes wall joint work and ceiling joint work. In the wall joint work, when the project inside work adopts the cement mortar + putty process, the wall joint is sealed and compacted with anti-cracking mortar, and when the light steel keel decorative panel is used, the wall joint is sealed with a PE rod and then a fire plate is used. In the ceiling joint work, a ceiling module unit is installed below the composite board. The ceiling module unit includes a hanging rod 16, a ceiling keel assembly, and a ceiling board 19. The hanging rod 16 suspends the ceiling keel assembly below the composite board, and the ceiling board 19 is laid below the ceiling keel assembly.

To facilitate subsequent pipeline 20 maintenance, the interfaces of the junction box 22 and the pipeline 20 are installed near the access hole 25, which is provided on the ceiling board 19. In addition, the mechanical and electrical pipeline is connected to the main keel 17 or the secondary keel 18 by a connecting piece 27, which can be a screw rod.
[0038] The wall system is located in the inner wall of the side plate of the template unit, i.e. the indoor side of the side plate of the template unit. Of course, it can also be arranged on the inner wall of the end plate of the pentahedron module unit. The wall system includes a wall keel assembly and a decorative panel 15. The decorative panel 15 and the side plate or the end plate maintain a spacing to form a cavity, and the wall keel assembly is installed in the cavity to connect the side plate and the decorative panel 15. The wall keel assembly includes a horizontal keel 13 and a vertical keel 14. Part of the vertical pipeline 20 in the mechanical and electrical pipeline can be fixed inside the cavity of the wall system. The decorative panel 15 is provided with a wire box 24 and / or a switch box 23.
[0039] The inside of the side plate joint of adjacent module units corresponds to the joint position of the adjacent two decorative panels 15, and a wall reserved section 10 is arranged. The wall reserved section 10 is not provided with a decorative panel 15. The wall reserved section 10 is located at both ends of the ground reserved slot 9 and can be compacted with concrete.
[0040] Part of the water pipe system is located above the ceiling board, and part of the water pipe system is arranged outside the side plate of the pentahedron module unit and the tetrahedron module unit. The water pipe system includes a drain pipe 7 arranged outside the side plate and a water pipe 21 arranged above the ceiling board. The water pipe 21 is connected to the drain pipe 7 through a three-way sleeve 26 arranged on the drain pipe 7. The drain pipe 7 outside the side plate has multiple branches, and each branch is connected through a four-way 8.
[0041] In another aspect, to increase the electromechanical pipeline laying path, the ground can adopt overhead ground, and the pipeline 20 can be laid inside the cavity under the floor 11, reducing the amount of material used. The edge of the floor 11 is also provided with a skirting board 12.
[0042] Compared with the "formwork" system used in the traditional high-rise MIC building, the MIC structure system of the embodiment adopts a frame structure stress system, and the stress components are four-corner column steel bars and four-edge beam steel bars which are bound on site, and the cast-in-place concrete. The steel bar binding and formwork setting engineering quantity are greatly reduced. At the same time, the high-rise large-span space module unit needs to consider the lateral horizontal force, and the joints between the adjacent left and right module units need to be reinforced. The MIC structure system of the embodiment sets a reserved steel bar notch at the splicing joint of the composite slab, and the steel bar is placed in the reserved steel bar notch on site without binding with the surrounding steel bar truss, which is convenient for construction and reduces the on-site steel bar binding workload. At the same time, the ground reserved slot is also set at the bottom plate splicing joint between the module units, and the steel bar is bound and the concrete is poured in the ground reserved slot on site, which increases the pull force between the adjacent left and right module units, improves the integrity, seismic resistance and lateral force performance of the MIC building, and makes the MIC system suitable for high-rise large-span space scenarios, while reducing the on-site workload and accelerating the construction progress.
