Description

Technical Field

[0001] This utility model application belongs to the field of prefabricated housing technology, and specifically relates to a prefabricated house. Background Technology

[0002] In the construction industry, prefabricated buildings are an important component of modern urbanization. Due to their convenience and efficiency, they are increasingly widely used in construction projects. Prefabricated houses offer numerous advantages, including fast construction speed, low cost, controllable quality, and environmental friendliness and energy efficiency, while also flexibly adapting to diverse needs. First, the components of prefabricated houses can be pre-produced in factories, requiring only on-site assembly, significantly reducing wet work and drastically shortening the construction period—a process that could take months or even years with traditional construction methods. Second, prefabricated houses are cost-effective, effectively reducing labor and material costs through factory-based, standardized production. Furthermore, the quality and safety of prefabricated houses are guaranteed. The use of reinforced concrete or modular technology significantly improves the quality of components and living comfort, reduces complex procedures, lowers safety hazards during construction, and ensures airtightness, waterproofing, and earthquake resistance. Finally, prefabricated houses exhibit excellent environmental and sustainable development characteristics, effectively reducing construction waste, and the reusable modules align with green building principles. Finally, prefabricated houses also have excellent flexibility and applicability. Through modular design, they can be quickly expanded or adjusted and are suitable for various scenarios such as residential buildings, dormitories, and public buildings. They can even meet emergency resettlement needs.

[0003] As prefabricated housing becomes increasingly popular and technology advances, the requirements for it are also rising. Current prefabricated housing construction remains relatively complex, and to ensure the integrity and safety of the building, traditional reinforced concrete structures are still used for each prefabricated component. This results in a large self-weight, making it inconvenient for hoisting, assembling, and transporting the prefabricated parts as a whole. However, after prefabricated houses are manufactured in factories, they are typically transported to various locations. Therefore, prefabricated houses need to meet high standards of structural strength, overall safety, energy efficiency, comfort, fire resistance, and sound insulation, while also being modular and lightweight.

[0004] Therefore, there is an urgent need to design a new type of prefabricated house. This prefabricated house should have high structural strength, meet the requirements of overall rigidity and safety, and at the same time meet the requirements of modular design, industrialized production, lightweighting, and good energy-saving, fireproof, and sound insulation technologies, so as to improve the economic benefits of enterprises, promote industry development, and create good social benefits.

[0005] This utility model application discloses a prefabricated house to solve the problems existing in the prior art.

[0006] To achieve the above objectives, this utility model provides a prefabricated house with a rectangular structure, consisting of several prefabricated wall panels and a prefabricated roof panel. It includes: four support columns for load-bearing, respectively located at the four corners of the rectangular structure, each support column being fixedly connected to two adjacent prefabricated wall panels; and several support beams for load-bearing, respectively fixedly mounted above the corresponding prefabricated wall panels, with each support beam's end fixedly connected to an adjacent support column, and the upper end face of each support beam fixedly connected to the lower end face of the prefabricated roof panel.

[0007] Furthermore, the support columns are H-beams.

[0008] Furthermore, several embedded parts are pre-embedded at intervals along the four perimeters of the precast wall panel, and the outer end face of the embedded parts is flush with the side end face of the precast wall panel for fixed connection with the support column or support beam; several embedded parts are pre-embedded at intervals along the four perimeters of the precast top slab, and the outer end face of the embedded parts is flush with the bottom surface of the precast top slab for fixed connection with the support beam.

[0011] Furthermore, one end of the embedded part located in the precast top slab is exposed on the side end face of the precast top slab, forming a square hole, while the other end of the pipe is embedded in the wall.

[0012] Furthermore, at least one of the other end faces of the embedded part is fitted with a bolt, an extended nut is fitted on the bolt, the head of the bolt is located inside the embedded part, and the shank of the bolt and the extended nut are embedded in the concrete.

[0013] Furthermore, the support beam is an H-beam, installed in an I-shape on the precast wall panel. The lower flange of the support beam has several lower connecting holes that match the through holes, used for fixed connection with the precast wall panel. The upper flange of the support beam has several upper connecting holes that match the through holes, used for fixed connection with the precast roof slab. The upper flange and web of the support column are respectively vertically fixed with connecting plates, all used for fixed connection with the support beam.

[0014] Furthermore, the upper connecting holes are all located at the outer ends of the support beam.

[0015] Furthermore, it also includes: four bottom beams, which are fixedly installed at the bottom of each precast wall panel.

[0016] The advantages and positive effects of this utility model are:

[0017] 1. The prefabricated house disclosed in this utility model application has a main load-bearing structure consisting of vertical support columns and horizontal support beams, which are connected by nodes to form a frame structure. This frame structure serves as the main load-bearing structure, giving the prefabricated house excellent structural strength, load-bearing capacity, integrity, and seismic performance. The prefabricated wall panels on all four sides and the prefabricated roof slab are all made of prefabricated lightweight partition walls. These prefabricated lightweight partition walls are cast using foamed concrete, forming dense, independent air-filled cavities within the wall panels, effectively reducing the density of the wall panels. Furthermore, the foamed cavities possess excellent water-repellent properties, giving the prefabricated lightweight partition walls excellent sound insulation, fire resistance, and thermal insulation performance. Simultaneously, the interior is equipped with double-layered, bidirectional steel wire mesh, and a fiberglass mesh is laid on the surface to ensure the structural strength and integrity of the prefabricated lightweight partition walls, ultimately forming a high-strength prefabricated lightweight partition wall. In addition, connectors are pre-embedded around the prefabricated lightweight partition wall panels to effectively connect them with the supporting columns and supporting beams (usually steel profiles) frame structure to form an integrated house.

[0018] In summary, this prefabricated house possesses high structural strength, meeting overall rigidity and safety requirements, while also satisfying the needs of modular design, industrialized production, and lightweight construction. Furthermore, it exhibits excellent energy-saving, fire-resistant, and sound-insulating properties.

[0040] The specific embodiments of this utility model application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this disclosure.

[0041] In the technical solutions disclosed in this utility model application, unless otherwise stated, directional terms such as "up," "down," "left," and "right" generally refer to those defined based on the drawing direction of the corresponding figures, while "inner" and "outer" refer to those inside and outside relative to the outline of the component or structure itself. Furthermore, in the description of the accompanying drawings, the same reference numerals in different figures denote the same elements.

[0042] This utility model application discloses a prefabricated house with a rectangular parallelepiped structure, such as... Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, it includes: a structure consisting of several precast wall panels 3 and a precast roof panel 6, and also includes:

[0043] Four support columns 1 are used for load bearing and are respectively set at the four corners of the prefabricated house cuboid structure. Each support column 1 is fixedly connected to two adjacent prefabricated wall panels 3.

[0044] Several support beams 2, used for load bearing, are fixedly installed above the corresponding precast wall panels 3, and the end of each support beam 2 is fixedly connected to the adjacent support column 1, and the upper end face of each support beam 2 is fixedly connected to the lower end face of the precast top slab 6.

[0045] In the above technical solution, the prefabricated house has a cuboid structure, including both ordinary cuboid structures and special cuboid structures such as cubes. The prefabricated wall panels 3 and prefabricated roof panels 6 are prefabricated lightweight partition walls. These lightweight partition walls are made of foamed concrete, with a double-layered, bidirectional steel wire mesh 10 laid inside. After the foamed concrete is poured, a fiberglass mesh is laid on the surface to increase surface strength. The main raw materials of the foamed concrete are cement, polymer-modified admixtures, and water. After being mixed evenly, air bubbles are injected into the mixer through a physical foaming machine, filling the cement slurry with dense air bubbles. The added polymer modifiers form a hydrophobic surface layer on the air bubble surface. After the cement slurry solidifies, it forms dense, independent, air-bubble-like cavities that are not interconnected, preventing water molecules from penetrating. This gives the foamed concrete wall excellent thermal insulation, sound insulation, waterproofing, and fireproofing properties. The prefabricated lightweight partition wall panels primarily serve as enclosures; while the main load-bearing structures are the vertical support columns 1 and the horizontal support beams 2, both of which are steel structure systems. This achieves a balance between the building's load-bearing capacity, stability, safety, and lightweight design, significantly optimizing the product and bringing good economic benefits to the company.

[0046] In this embodiment, such as Figure 1 , Figure 2 , Figure 3 , Figure 11 As shown, support column 1 is an H-beam.

[0047] In some specific embodiments, a number of embedded parts 4 are pre-embedded at intervals along the four perimeters of the precast wall panel 3, and the outer end face of the embedded part 4 is flush with the side end face of the precast wall panel 3, for fixed connection with the support column 1 or support beam 2; a number of embedded parts 4 are pre-embedded at intervals along the four perimeters of the precast top plate 6, and the outer end face of the embedded part 4 is flush with the bottom plate surface of the precast top plate 6, for fixed connection with the support beam 2.

[0048] In this technical solution, the outer end faces of the embedded parts 4 in the precast wall panel 3 are all exposed and flush with the side end faces of the precast wall panel 3, used for fixed connection with the support column 1 or support beam 2. The fixing method can be welding, bolt connection, etc. Similarly, the precast roof slab 6 follows the design of the precast wall panel 3, with several embedded parts 4 pre-embedded at intervals along its four perimeters. The outer end faces of the embedded parts 4 are all exposed and flush with the bottom surface of the precast roof slab 6, and are fixedly connected with the support beam 2. Specifically, as shown... Figure 6 As shown, the embedded part 4 is a square tube structure with an internal hollow structure, and a through hole 401 is made on the outer end face of the embedded part 4.

[0049] Furthermore, such as Figure 7As shown, at least one end of the embedded part 4 located in the precast wall panel 3 is exposed on the wall surface of the precast wall panel 3, forming a square hole; the corresponding positions of the flange plate and web plate of the support column 1 are provided with mounting holes 101 that match the through hole 401.

[0050] In this design, the embedded part 4 in the precast wall panel 3 is bolted to the support column 1, and at least one end of the embedded part 4 in the precast wall panel 3 protrudes from the wall surface of the precast wall panel 3, forming a square hole. The square hole is for the operator to operate when bolting the two together. Preferably, both ends of the embedded part 4 protrude from the wall surface of the precast wall panel 3, which is most convenient for the operator.

[0051] Similarly, as with the design described above, in some implementations, such as Figure 9 As shown, one end of the embedded part 4 located in the precast top slab 6 is exposed on the side end face of the precast top slab 6, forming a square hole, while the other end of the pipe is embedded in the wall.

[0052] Furthermore, such as Figure 8 Or such as Figure 10 As shown, in the precast wall panel 3 or precast roof panel 6, at least one of the other end faces of the embedded part 4 is fitted with a bolt 8, and an extended nut 9 is mounted on the bolt 8. The head of the bolt 8 is located inside the embedded part 4, and the shank of the bolt 8 and the extended nut 9 are embedded in the concrete. This design can enhance the connection strength between the embedded part 4 and the precast wall panel 3, and between the embedded part 4 and the precast roof panel 6, thereby increasing the overall structural strength of the precast house. Specifically, high-strength bolts can be used for the bolt 8 to further strengthen the connection.

[0053] In other implementation methods, such as Figure 1 , Figure 6 , Figure 11 , Figure 12 As shown, the support beam 2 is an H-beam, which is installed on the precast wall panel 3 in an I-shape. The lower flange of the support beam 2 is provided with several lower connecting holes 201 that match the through holes 401, which are used to fix the support beam 2 to the precast wall panel 3. The upper flange of the support beam 2 is provided with several upper connecting holes 202 that match the through holes 401, which are used to fix the support beam 2 to the precast top plate 6.

[0054] Connecting pieces 7 are vertically fixed to the upper flange plate and web plate of the support column 1, respectively, for fixed connection with the support beam 2.

[0055] In this design, the H-beams of the support beam 2 and the H-beams of the support column 1 are bolted together using connecting pieces 7. Preferably, the connecting pieces 7 can be fixedly mounted on the web of the support column 1 at the position where it meets the flange, and on the flange between the middle and the end (neither at the end nor in the middle), thus ensuring a flush connection between the support beam 2 and the support column 1.

[0056] Furthermore, all the upper connecting holes 202 are located on the outer ends of the support beam 2. This arrangement of all the upper connecting holes 202 on the outer ends of the support beam 2 makes it easiest for operators to connect and install the precast top slab 6 after it has been placed on the support beam 2.

[0057] In some other implementations, such as Figure 1 , Figure 2 As shown, it also includes: four bottom beams 5, which are fixedly installed at the bottom end of each precast wall panel 3. The bottom beams 5 can be connected to the precast wall panels 3 using a similar connection method as the support beams 2 and the precast wall panels 3, such as welding or bolting. Preferably, the bottom beams 5, support columns 1, support beams 2, and embedded parts 4 are all made of galvanized steel.

[0058] In addition, the prefabricated wall panel 3 also has window openings 301 for installing windows and door openings 302 for installing doors.

[0059] The preferred embodiments of this utility model application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the specific details of the above embodiments. Within the scope of the disclosed technical concept, various simple modifications can be made to the technical solution of this utility model application, and these simple modifications all fall within the protection scope of this application.

[0060] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, this application will not describe the various possible combinations separately.

[0061] Furthermore, various different embodiments of this utility model application can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this utility model application.
