Description

Technical Field

[0001] This utility model relates to the field of building engineering, and in particular to a modular structure system for reinforced concrete core tubes. Background Technology

[0002] 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 buildings have the highest assembly rate and the highest degree of industrialization.

[0003] Currently, there are two main types of modular buildings: steel-structured modular buildings and concrete modular buildings. Steel-structured modular buildings offer advantages such as convenient connections and fast construction speed, but also suffer from drawbacks such as high steel consumption and high structural costs. Furthermore, these buildings have low lateral stiffness and poor comfort. Concrete modular buildings are relatively cheaper than steel structures, but they suffer from heavy overall module weight, making transportation and hoisting inconvenient, and difficulties in module connection. Utility Model Content

The multiple sets of ear plates on one side of the concrete core tube are arranged from the top end to the bottom end of the concrete core tube, and the multiple sets of ear plates on both sides of the concrete core tube are symmetrically arranged.

[0007] Furthermore, the horizontal connection assembly also includes a friction plate, which is stacked with the ear plate and connected to it via the pin.

[0008] Furthermore, the concrete core tube includes shear walls and connecting beams. The shear walls are multiple vertically arranged sections, and the connecting beams are erected between adjacent shear walls. The shear walls and the connecting beams encircle and form a hollow core tube.

[0009] Furthermore, the concrete core tube also includes reinforcing bars, one end of which is pre-embedded in the shear wall, and the other end extends out to form a fixed connection with the post-cast concrete of the horizontally adjacent module unit.

[0010] Furthermore, the number of the module units is multiple, and the multiple module units are stacked alternately to form a multi-layer rectangular main structure.

[0011] Furthermore, there are multiple concrete core tubes, which are horizontally connected to form a whole, and multiple module units are arranged around the multiple concrete core tubes.

[0012] Furthermore, it also includes a module connection component. The module unit is a rectangular frame structure. The module connection component is disposed at the eight endpoints of the module unit, and two adjacent module units are connected by the module connection component.

[0013] Furthermore, the module connection component includes at least one C-shaped plug block and at least one C-shaped plug cylinder, wherein the C-shaped plug block can be inserted into the C-shaped plug cylinder to form a grouting space.

[0014] Furthermore, the module unit is a steel structure or a concrete structure.

[0015] The beneficial effects of this utility model are as follows:

[0016] The core tube and modular units of this invention are detachably connected to each other, and can be used independently or combined with the core tube, or combined with a steel frame or steel bracing to form a prefabricated building. It has advantages such as convenient module connection, fast construction speed, and lightweight modules, as well as the low cost of concrete modules. Attached Figure Description

[0027] Example 1

[0028] Please refer to Figure 1As shown in Embodiment 1 of this application, a modular reinforced concrete core tube structure system includes a concrete core tube 10, module units 20, horizontal connecting components 30, and module connecting components 40. Module units 20 are connected to the concrete core tube 10 via horizontal connecting components 30, and adjacent module units 20 are connected via module connecting components 40. There are multiple module units 20, which are stacked in an alternating manner to form a multi-layer rectangular main structure. There are multiple concrete core tubes 10, which are horizontally connected to form a whole, and multiple module units 20 are arranged around multiple concrete core tubes 10.

[0029] Combination Figure 2 As shown, the horizontal connecting assembly 30 includes a pin 31, a friction plate 32, and ear plates 33 respectively disposed on the concrete core tube 10 and the module unit 20. The friction plate 32 is clamped between two horizontally adjacent ear plates 33 and connected by the pin 31. A single module unit 20 is connected to the concrete core tube 10 by four sets of horizontal connecting assemblies 30, and each set of horizontal connecting assemblies 30 has at least one ear plate 33 on the concrete core tube 10 or the module unit 20. Preferably, one of the concrete core tube 10 or the module unit 20 has two ear plates 33.

[0030] like Figure 3 As shown, the concrete core tube 10 includes shear walls 11 and connecting beams 12. The shear walls 11 are multiple vertically arranged sections, and connecting beams 12 are erected between adjacent shear walls 11. The shear walls 11 and connecting beams 12 encircle a hollow core tube. Multiple sets of ear plates 33 are arranged on opposite sides of the concrete core tube 10. The ear plates 33 on one side of the concrete core tube 10 are arranged from the top to the bottom of the shear walls 11, and the ear plates 33 on both sides of the concrete core tube 10 are symmetrically arranged. The ear plates 33 on the same side of the shear walls 11 are arranged in two rows. Multiple horizontally placed reinforcing bars 50 are provided between the two symmetrical sets of ear plates 33. One end of the reinforcing bars 50 is embedded in the shear wall 11, and the other end extends out and forms a fixed connection with the post-cast concrete of the horizontally adjacent module unit 20.

[0031] like Figure 4 As shown, module unit 20 is a rectangular frame steel structure. Module connection components 40 are located at the eight ends of module unit 20, and adjacent module units 20 are connected by module connection components 40. Module unit 20 includes columns 21, beams 22, connecting beams 23, a top plate 24, a bottom plate 25, and a connecting plate 26. Every eight beams 22 and every four columns 21 are connected to the module connection components 40 to form a single frame. The top plate 24 is connected to the four upper beams 22, and the bottom plate 25 is connected to the four lower beams 22.

[0032] One end of each of the four connecting beams 23 is connected to the module connecting assembly 40 and extends horizontally outward from the four crossbeams 22. The other end of each connecting beam 23 is provided with an ear plate 33 of the horizontal connecting assembly 30.

[0033] When the module unit 20 is connected to the concrete core tube 10, the reinforcing bars 50 of the concrete core tube 10 overlap the connecting plate 26 of the module unit 20, and the other end of the reinforcing bars 50 is fixedly connected to the connecting plate 26 by post-pouring concrete. Of course, the connecting plate 26 can also have the reinforcing bars 50 pre-embedded.

[0034] Combination Figure 5 As shown, the modular connection assembly 40 includes at least one C-shaped plug-in block 41 and at least one C-shaped plug-in cylinder 42. The C-shaped plug-in block 41 can be inserted into the C-shaped plug-in cylinder 42 to form a grouting space. The bottoms of both the C-shaped plug-in block 41 and the C-shaped plug-in cylinder 42 are connected to the column 21, and the sidewall of the C-shaped plug-in cylinder 42 is connected to the crossbeam 22. When two adjacent modular connection assemblies 40 are plugged in, a buffer gap is formed between the C-shaped plug-in cylinders 42 of the two modular connection assemblies 40.

[0035] Multiple first studs 43 extend horizontally outward from the outer wall of the C-shaped plug-in block 41, arranged in multiple vertical columns. Multiple second studs 44 extend horizontally inward from the inner wall of the C-shaped plug-in cylinder 42, also arranged in multiple vertical columns. After the C-shaped plug-in block 41 and the C-shaped plug-in cylinder 42 are plugged in, the vertical columns of the first studs 43 and the vertical columns of the second studs 44 are staggered horizontally. The first studs 43 and the second studs 44 have the same structure. After the C-shaped plug-in block 41 and the C-shaped plug-in cylinder 42 are plugged in, a grouting space is formed. Grout is injected into the grouting space, and after the grout solidifies, the two module connection components 40 are tightly connected. Because the grouting space is equipped with first studs 43 and second studs 44, the reliability of the module unit 20 connection is improved.

Multiple module units 20 are stacked in an alternating manner to form a multi-layer rectangular main structure. Multiple concrete core tubes 10 are horizontally connected to form a whole, and multiple module units 20 are arranged around multiple concrete core tubes 10.

[0039] In this embodiment, the concrete core tube 10, the horizontal connecting component 30, and the module connecting component 40 have the same structure, and will not be described again here.

[0040] Module unit 20 includes columns 21, beams 22, connecting beams 23, a top plate 24, a bottom plate 25, and connecting plates 26.
