Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated buildings, and in particular to a light and extremely fast prefabricated building system. Background Art

[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories, where building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in factories, transported to construction sites, and assembled and installed on site through reliable connection methods. Prefabricated buildings mainly include prefabricated concrete structures, steel structures, modern wooden structures, etc., and are representatives of modern industrialized production methods because they use standardized design, factory production, assembly construction, information management, and intelligent applications.

[0003] In this era, prefabricated buildings have shown their advantages of rapid construction and have achieved remarkable results in the rapid construction of medical buildings, resettlement sheds and many other aspects. Prefabricated buildings have fast construction speed and low production costs. While greatly shortening the construction period and saving manpower, they have also achieved energy conservation, environmental protection and quality improvement of buildings. However, at this stage, research on prefabricated buildings is still insufficient and it is difficult to form a reasonable system. Prefabricated buildings themselves are also facing many problems, which are mainly divided into three categories, as follows:

[0004] ① There are many types of components and parts, which are difficult to manage. At present, there are many types of components and parts in prefabricated buildings. According to different locations, they can be divided into beams, columns, wall panels, floors, doors, windows, etc. Different components and parts can only be used in specific locations in the building. Even components and parts in the same location have different sizes and specifications, which leads to a large number of components and various forms of components in the building, which are difficult to manage uniformly.

[0005] ② Errors are prone to occur during the on-site assembly of components. In the process of prefabrication of building components, a large number of various types of building components will appear in construction factories and construction sites. How to quickly identify and combine various building components has become a key technical difficulty for the rapid construction of prefabricated buildings. The current construction process of prefabricated buildings mainly relies on traditional manual experience identification and construction. The assembly process has high requirements for equipment and labor, low assembly efficiency, high cost, and is prone to errors. This has restricted the advantages of prefabricated buildings to a certain extent.

[0006] ③ It is difficult to form a recycling model in the operation stage of prefabricated buildings. At present, most of the components are assembled by bolt locking or even welding. It is extremely difficult or even impossible to disassemble them after the building is used. As a result, these components cannot be systematically recycled in the operation stage after on-site assembly, which makes it difficult to manage the operation of the entire life cycle.

[0007] In the prior art, although the light composite sandwich panels connected by locks have the advantages of easy assembly and disassembly, concealed structure, and firm tension, they can only complete the simple construction of panels. This connection method makes the overall strength low and the load-bearing capacity poor, and it is impossible to build multiple floors; it also lacks structural design in terms of wind and earthquake resistance; it is closed in space and single in form, and cannot form a real building.

[0057] In order to further explain the technical solution of the present invention, the present invention is described in detail below through specific embodiments.

[0058] The present invention is a light-weight extremely fast assembled building system, comprising a plurality of pipe fittings 1, plate members 2, connecting members 3 and bolts 4.

[0059] The four sides of the pipe fitting 1 are provided with a plurality of locking grooves 11, which are arranged at equal intervals on the sides of the pipe fitting 1. Pins 12 are arranged in the locking grooves 11, and both ends of each side of the pipe fitting 1 are provided with a plurality of through holes 13; the pipe fitting 1 can be used as a beam or a column to form the main frame of the building;

[0060] The four sides of the plate 2 are provided with a rotating buckle 21 corresponding to the locking groove 11; Fig. 9 As shown, during assembly, the rotating buckle 21 is inserted into the corresponding locking buckle groove 11 and the fastening pin 12 is rotated to make the plate 2 and the pipe 1 seamlessly spliced;

[0061] The connector 3 is made of aluminum alloy, and includes a cubic connector body 31 and a connector column 32. The connector body 31 is provided with the connector column 32 on at least one side, and the six sides thereof are provided with or without the connector column 32 according to whether the pipe 1 is actually connected. The connector column 32 matches the inner cavity of the pipe 1, and a screw hole 321 is provided at the end thereof, which is opposite to the through hole 13. Fig.11 As shown, during assembly, the connecting column 32 is inserted into the end of the pipe 1 so that the connecting body 31 fits on the end of the pipe 1 , and the bolt 4 passes through the through hole 13 and is locked into the screw hole 321 .

[0062] refer to Figures 1 to 14 Shown is a specific embodiment of the present invention.

[0063] There are two implementation methods of the above pipe fitting 1: ① Reference Figure 4 As shown, the pipe fitting 1 is composed of an aluminum alloy pipe fitting inner core 1A and a PU layer 1B coated on the outer surface of the pipe fitting inner core 1A, which can reduce the cost and weight while meeting the strength of the pipe fitting 1; ② Reference Figure 5 As shown, the pipe fitting 1 is integrally formed of an aluminum alloy material and has higher mechanical strength and supporting strength, which is particularly important when constructing multi-story buildings.

[0064] The pin 12 is parallel to the side surface of the pipe 1 where it is located, and the pin 12 is also parallel to the end surface of the pipe 1 , so when the plate 2 and the pipe 1 are assembled, the rotating buckle 21 can be matched and buckled onto the pin 12 .

[0065] The above-mentioned panel 2 is a PU composite sandwich panel, refer to Figures 6 to 8 As shown, the types of panels 2 can be divided into pure flat panels 2, panels with doors 2 and panels with windows 2, etc., or panels 2 with other functions, that is, functional building structures such as doors 22, windows 23, air-conditioning holes, etc. required for the building can be set on the panels 2.

[0066] According to the requirements of connecting pipe fittings 1 in actual assembly, refer to Fig.10 As shown, connecting columns 32 can be arranged on the six faces of the connecting body 31, and the faces on which the connecting columns 32 are arranged may also be different depending on the position of the connecting member 3 in the building. For example, when the connecting member 3 only connects two pipes 1 arranged in a collinear manner, a connecting column 32 is arranged on one set of opposite faces of the connecting body 31; or when the connecting member 3 is located at the bottom corner or top corner of the building, the connecting member 3 needs to connect three pipes 1 that are perpendicular to each other, then connecting columns 32 are arranged on three faces of the connecting body 31 (the three faces are adjacent to each other).

[0067] The present invention also includes a pipe insulation shell 5, which is composed of a PU composite inner core 51, an aluminum skin 52 and a plastic buckle 53. The aluminum skin 52 is arranged on the outer side of the PU composite inner core 51, and the inner side of the PU composite inner core 51 matches the side profile of the pipe 1. The plastic buckle 53 is arranged on the inner side of the PU composite inner core 51 and is arranged opposite to the locking groove 11. The end of the plastic buckle 53 is provided with a slot 531 for the pin 12 to cooperate with. In actual use, the pipe insulation shell 5 has a protective effect of the aluminum skin 52, and the PU composite inner core 51 realizes heat insulation and heat preservation. In this embodiment, the shape of the plastic buckle 53 matches the shape of the locking groove 11 to ensure the fit between the pipe insulation shell 5 and the pipe 1, and to avoid shaking of the pipe insulation shell 5 after installation. Reference Fig.12 As shown, the types of pipe insulation shells 5 can be divided into straight-line insulation shells and L-shaped insulation shells. The pipes 1 in the plane position are insulated by straight-line insulation shells, and the pipes 1 in the corner position are insulated by L-shaped insulation shells. In addition, Fig.12 The h and j parts are respectively reinforced versions of the I-shaped and L-shaped insulation shells, and are characterized in that the thickness of the PU composite inner core 51 is increased. Fig.13 As shown, when assembling the pipe insulation shell 5, it is only necessary to align the plastic buckle 53 with the locking groove 11 of the corresponding pipe 1 and snap it in, thereby effectively achieving the thermal insulation effect.

[0068] refer to Fig.14As shown, when the structural stability needs to be improved, the windproof structure of the present invention directly connects one end of the windproof rope to the pin 12 of the pipe 1 through a lock, and the other end is connected to the foundation through a fixing component (such as a ground nail).

[0069] Note: The above PU refers to polyurethane materials.

[0070] refer to Figures 15 to 20 As shown, the present invention also includes an assembled canopy assembly, which includes a canopy board 6, a first assembly, a second assembly, and a third assembly. The first assembly includes a vertical rod 7 and a connecting rod 8; the vertical rod 7 is vertically connected to the side of the vertical pipe 1; the lower end of the connecting rod 8 is pivotally matched with the vertical rod 7; the second assembly includes two connecting beams 9 arranged in parallel, and a cover plate 10; the two connecting beams 9 are pivotally matched to adjust the relative angle, and one of the connecting beams 9 is horizontally connected to the side of the horizontal pipe 1; the cover plate 10 is respectively connected to the two connecting beams 9 to maintain the relative angle of the two connecting beams 9; the third assembly is a surrounding rod 20, which matches the outer contour of the canopy board 6, and cooperates with another connecting beam 9' to surround and connect to the four side edges of the canopy board 6, and the upper end of the connecting rod 8 is connected to the lower surface of the surrounding rod 20 at the end position of the canopy board 6.

[0071] The above-mentioned first component is provided with two groups, which are respectively arranged at the two ends of the canopy board 6 to support the two ends of the canopy board 6 and achieve the purpose of balanced force.

[0072] The connecting rod 8 comprises an outer rod 81 and an inner rod 82 that are telescopically matched, and a limiting mechanism disposed between the outer rod 81 and the inner rod 82. When the limiting mechanism is closed, the outer rod 81 and the inner rod 82 are relatively fixed, that is, the overall length of the connecting rod 8 remains unchanged. When the limiting mechanism is opened, the inner rod 82 is telescopically extended at the end of the outer rod 81, and the overall length of the connecting rod 8 can be adjusted according to the installation inclination angle of the canopy board 6. In this embodiment, the limiting mechanism is a fixed knob 83 disposed at the upper end of the outer rod 81.

[0073] The pivotal connection of the two connecting beams 9 is located at the lower edge of the facing surfaces; the cover plate 10 is arranged along the axis direction of the connecting beam 9, and the two connecting beams 9 are connected on both sides thereof. When one connecting beam 9 is fixed on the building, the side of the other connecting beam 9' facing away from the other can be rotated around the lower edge as an axis to adjust the angle, so as to adapt to the installation angle required by the canopy board 6, and then locked with the cover plate 10 to maintain the adjusted angle. In this embodiment, the two connecting beams 9 are pivotally connected by hinges 30; the cover plate 10 is riveted to the connecting beam 9 by rivets.

[0074] The above-mentioned fence rod 20 is in a concave shape and is an integrally formed component to ensure supporting strength.

The rotating buckle 21' and the pin 12' are respectively provided on the two connected parts to realize detachable assembly: the rotating buckle 21' is inserted and rotated to align the position of the pin 12', so that the rotating buckle 21' is buckled on the pin 12' to complete the quick assembly. When disassembly is required, the rotating buckle 21' is rotated in the opposite direction to disassemble the two connected components. In this embodiment, the outer ends of the surrounding rod 20 are respectively provided with rotating buckles 21' and pins 12' to realize the parallel installation of multiple canopy boards 6.

[0076] The prefabricated canopy assembly is provided with a second component and a third component to respectively connect the four side edges of the canopy board 6, which serve as the installation frame of the canopy board 6, and then the first component is used to realize the oblique support of the installation frame to complete the assembly and support of the canopy board 6 on the light prefabricated building, so as to facilitate the rapid disassembly and assembly of the canopy board 6, and at the same time improve the connection between the canopy board 6 and the building structure system, thereby improving the strength of the entire structural system.

The ends of the pipe fittings 1 are provided with connecting parts 3 for overlapping the pipe fittings 1. The sides of the pipe fittings 1 are provided with locking grooves 11 corresponding to the rotating buckles 21 of the plate 2.
