Description

Technical Field

[0001] The present invention belongs to the technical field of prefabricated assembled concrete buildings, and in particular relates to an assembled module unit and a building structure that is waterproof, lightweight and heat-insulating in one. Background Art

[0002] In recent years, with the national policy of vigorously developing prefabricated buildings, a new type of prefabricated building has emerged - prefabricated modular buildings. Prefabricated modular building technology is a new type of building technology with standardized design, industrialized production, supporting supply, and prefabricated construction. Prefabricated modular buildings divide the entire building into independent prefabricated modules according to the layout of each functional space of the building. The prefabricated functional modules are prefabricated in the factory and transported to the construction site. The independent prefabricated functional modules are assembled into an integral building using a scientific and reasonable connection method. Compared with traditional prefabricated buildings based on a single prefabricated component level, prefabricated modular buildings have a high degree of integration, fewer on-site connection nodes during the entire construction process, convenient construction and installation, fast on-site construction speed, short cycle, easy quality assurance, long service life, low cost, and basically can achieve non-wet operation, improve the working environment, reduce pollution, save labor, and can achieve true prefabricated construction and industrialized construction. It is the ultimate form of prefabricated building development.

[0003] At present, the prefabricated functional modules used in existing prefabricated modular buildings can be divided into prefabricated steel structure modular buildings and prefabricated concrete modular buildings according to the materials. Prefabricated steel structure modular buildings use corner columns to bear the weight, and have the advantages of flexible building design, high bearing capacity, fast construction speed, and light weight. However, the prefabricated steel structure modular building uses a large amount of steel, resulting in high costs. At the same time, the durability and living comfort are poor. Therefore, it is mostly used in low-rise office buildings or emergency buildings, and rarely used in residential buildings. Prefabricated concrete modular buildings use load-bearing walls to bear the weight, use a small amount of steel, low cost, and have good fire resistance, corrosion resistance, thermal insulation, durability and living comfort. It is a solution suitable for high-quality modular buildings, but the self-weight of prefabricated concrete modular buildings is large. Summary of the invention

[0029] See also Figure 1 , Figure 2a to Figure 2c , Figure 1 1 is a schematic structural diagram of a waterproof, lightweight, and heat-insulating integrated assembled module unit provided by an embodiment of the present invention. Figure 2a to Figure 2c : is a plan view of a waterproof, lightweight and heat-insulating integrated assembled module unit provided by an embodiment of the present invention, wherein: Figure 2b yes Figure 2a The cross-section of the AA surface in the middle. Figure 2c yes Figure 2a Cross-section view of the middle BB surface.

[0030] The first aspect of the present embodiment provides a waterproof, lightweight and heat-insulating integrated assembled module unit, comprising: a wall frame structure 10, an autoclaved lightweight concrete (ALC) structure 20 and a composite non-disassembly insulation structure 30. The two opposite side walls of the wall frame structure 10 have a hollow portion 16, and a vertical connection structure and a horizontal connection structure are provided in the wall frame structure 10. The ALC structure 20 covers the hollow portion 16 and is connected to the wall frame structure 10. The composite non-disassembly insulation structure 30 is connected to the outer side of the ALC structure 20 and the other two opposite side walls of the wall frame structure 10.

[0031] Specifically, this embodiment provides a hollow portion 16 on the side wall of the wall frame structure 10, and covers the ALC structure 20 on the hollow portion 16 to replace the ordinary concrete wall in the traditional prefabricated concrete module building, so as to reduce the dead weight of the prefabricated module unit. In addition, the outer surface of the prefabricated module unit is covered with a composite non-disassembly insulation structure 30, which can realize the integration of the insulation structure. When a plurality of prefabricated module units are assembled, two adjacent prefabricated module units in the vertical direction are connected as a whole through a vertical connection structure, and two adjacent prefabricated module units in the horizontal direction are connected as a whole through a horizontal connection structure.

[0032] In this embodiment, if Figure 1 As shown, the wall frame structure 10 includes: a top plate 11, a beam 12, a short-limb shear wall 13 and a window panel 14. Among them, the beam 12 is arranged on the lower surface of the top plate 11. The short-limb shear wall 13 is vertically arranged at the four corners of the top plate 11 and connected to the lower side of the beam 12. The short-limb shear wall 13 and the beam 12 form a door opening 15 on the front wall of the top plate 11, and the short-limb shear wall 13 and the beam 12 form a hollow part 16 on the left and right walls of the top plate 11. The window panel 14 is arranged on the rear wall of the top plate 11, connecting the short-limb shear wall 13 and the beam 12 located on the rear wall of the top plate 11, and a window opening 17 is opened on the window panel 14.

[0033] Specifically, the top plate 11, beam 12, short-limb shear wall 13 and window plate 14 are all made of ordinary reinforced concrete materials, the end where the door opening 15 is located is the front end, the end where the window opening 17 is located is the rear end, the top plate 11 is the top end, and the bottom end is opposite to the top plate 11. The module unit of this embodiment is a bottom plate-free structure, that is, the bottom end of the wall frame structure 10 is hollowed out, which avoids the problem of the floor being too thick due to the overlap of the bottom plate of the upper module unit and the top plate of the lower module unit; when the waterproof, lightweight and heat-insulating integrated assembled module unit is erected on the ground, the ground is the bottom end, and when the waterproof, lightweight and heat-insulating integrated assembled module unit is erected on the rest of the structure, the top end of the rest of the structure is the bottom end. The two side walls (left and right ends) of the wall frame structure 10 are equivalent to the wall in the building structure.

[0034] Furthermore, combined with Figure 2a to Figure 2c At the hollow portion 16, the composite non-disassembly insulation structure 30 connects the ALC structure 20 and the beam 12 through a connector 32; at the short-limb shear wall 13, the composite non-disassembly insulation structure 30 connects the short-limb shear wall 13 and the beam 12 through a connector 32. It should be understood that the composite non-disassembly insulation structure 30 is provided with hollows corresponding to the door opening 15 and the window opening 17.

A groove is provided on one side of each ALC strip 21, and a protrusion that matches the groove is provided on the other side. The groove on the left side of an ALC strip 21 and the protrusion on the right side thereof are concave-convexly matched to achieve the connection of a plurality of ALC strips 21. Furthermore, the two ends of the ALC structure 20 are concave-convexly bonded to the short-limb shear wall 13.

Each composite non-disassembly insulation board slat 31 includes: an inner protective layer 311, an extruded polystyrene board (Extruded Polystyrene System, XPS) insulation layer 312, an outer protective layer 313 and an alkali-resistant glass fiber mesh 314. Among them, the inner protective layer 311, the XPS insulation layer 312 and the outer protective layer 313 are stacked in sequence, and the alkali-resistant glass fiber mesh 314 is arranged inside the outer protective layer 313.

[0037] Specifically, the inner protective layer 311 is arranged on the inner side of the XPS thermal insulation layer 312, and the outer protective layer 313 is arranged on the outer side of the XPS thermal insulation layer 312.

In this embodiment, the thickness of the inner protective layer 311 is 5 mm, and the thickness of the outer protective layer 313 is 20 mm.

[0038] like Figure 5 and Figure 6 As shown, holes are reserved in the composite non-removal insulation board slats 31. When the composite non-removal insulation board slats 31 are connected to the ALC structure 20 or the wall frame structure 10, the connector 32 passes through the reserved holes and is connected to the ALC structure 20 or the wall frame structure 10. In this embodiment, the composite non-removal insulation board slats 31 and the ALC structure 20 are also bonded by mortar to enhance the integrity of the structure. The inner side of the ALC structure 20 and the wall frame structure 10, as well as the outer side of the composite non-removal insulation structure 30, are also provided with anti-cracking mortar 33. For example, the thickness of the anti-cracking mortar 33 is 5 mm, and an alkali-resistant glass fiber mesh is also sandwiched in the middle of the anti-cracking mortar 33.

[0039] Specifically, when preparing the prefabricated module unit, the composite non-disassembly insulation structure 30 is used as the external non-disassembly formwork of the module unit, and the ALC structure 20 is used as the bottom non-disassembly formwork of the beam 12. After the composite non-disassembly insulation structure 30 and the ALC structure 20 are placed in corresponding positions, they are cast as a whole by concrete in the factory to obtain a concrete prefabricated module unit.

[0045] Furthermore, the box connector 43 adopts an integrated steel bar box connector, and the steel box is welded by Q235 steel plate, and the weld size is calculated according to the "Steel Structure Design Standard".

[0051] Furthermore, the connection hole 621 is a cross-shaped hole, which reserves a certain margin for the penetration of the first horizontal connecting steel bar 63, so as to avoid the situation that the first horizontal connecting steel bar 63 cannot penetrate due to errors in the installation process.
