[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Reference Figure 1-Figure 10 The present invention provides a green and sustainable fully modular prefabricated building, comprising:

[0035] A base 1, the top of which is detachably connected to a plurality of load-bearing wall panel assemblies via a connecting piece;

[0036] The intermediate floor assembly includes a floor frame assembly, which is detachably connected to the top of a plurality of load-bearing wall panel assemblies through a connecting piece, and a plurality of first connecting beams 8 and second connecting beams 9 are detachably connected in the floor frame assembly, and the positions of the plurality of first connecting beams 8 and second connecting beams 9 are arranged corresponding to the positions of the plurality of load-bearing wall panel assemblies, and a floor 7 is detachably connected between the floor frame assembly and the plurality of first connecting beams 8 and second connecting beams 9;

[0037] A plurality of wall panel assemblies are detachably connected between two adjacent load-bearing wall panel assemblies and the base 1 and the floor frame assembly. The wall panel assemblies include inner wall panels 23 and outer wall panels 24 , and a cavity is provided between the inner wall panels 23 and the outer wall panels 24 .

[0038] The main function of the load-bearing wall panel assembly is to support the middle floor slab assembly; the main function of the floor slab frame assembly is to connect the first connecting beam 8 and the second connecting beam 9 according to the actual layout position of the lower load-bearing wall panel assembly, so that the first connecting beam 8 and the second connecting beam 9 can be overlapped on the top of the load-bearing wall panel assembly, and at the same time cooperate with the first connecting beam 8 and the second connecting beam 9 to connect the corresponding floor slab 7; the main function of the cavity is to enable water pipes, circuit pipes and other structures to be arranged between the inner wall panel 23 and the outer wall panel 24. During the construction process, the water pipes, circuit pipes, etc. are first fixed on the inner side of the outer wall panel 24, and then the inner wall panel 23 is closed to conveniently realize the installation of the water pipes and circuit pipes. On the whole, the present invention can flexibly arrange the positions of the load-bearing wall panel components and the internal structure of the house according to the actual use requirements of the house, and can build the first connecting beam and the second connecting beam in the floor frame component according to the actual layout of the house, thereby realizing the construction of the middle floor and ensuring the structural stability of the middle floor. At the same time, when building the wall panels, by first arranging water pipes, circuit pipes and other structures on the inner side of the outer wall panels, the effect of simultaneous construction of waterways and circuits with the building can be achieved.

[0039] Further optimizing the scheme, the load-bearing wall panel assembly includes an L-shaped connecting plate 2, a plane connecting plate 12 and a T-shaped connecting plate 13, and the inner sides of the L-shaped connecting plate 2, the plane connecting plate 12 and the T-shaped connecting plate 13 are provided with reinforcing iron pieces, and the outer sides of the reinforcing iron pieces are wrapped with concrete;

[0040] The reinforcing iron parts in the planar connecting plate 12 include two groups of load-bearing columns 20 , and the two groups of load-bearing columns 20 are fixedly connected by a plurality of connecting rods 21 .

[0041] like Figure 2 and Figure 4 As shown, the L-shaped connecting plate 2 can be set at the corner of the building, the flat connecting plate 12 can be set between the long walls to shorten the length of the wall panel assembly and improve its durability. The T-shaped connecting plate 13 can be used to build another wall in the middle of the wall of the building, such as Figure 4 As shown, by the cooperation of two T-shaped connecting plates 13 and a group of L-shaped connecting plates 2, a smaller room can be built, rather than the conventional form of dividing the living space into two, making the house layout more flexible.

[0042] like Figure 7 As shown, during the construction process, two groups of load-bearing columns 20 are first connected by a plurality of connecting rods 21 , and then placed in a mold of a specific shape, and concrete is poured to form a planar connecting plate 12 .

[0043] Similarly, the T-shaped connecting plate 13 is formed by arranging three groups of load-bearing columns 20 in a T shape, welding the connecting rod 21, and pouring concrete in the corresponding T-shaped mold; the L-shaped connecting plate 2 is formed by arranging three groups of load-bearing columns 20 in an L shape, welding the connecting rod 21, and pouring concrete in the corresponding L-shaped mold.

[0044] To further optimize the solution, connecting components are respectively provided in the L-shaped connecting plate 2, the planar connecting plate 12 and the T-shaped connecting plate 13. The connecting component in the planar connecting plate 12 includes a connecting pipe 29 fixedly penetrated between the two load-bearing columns 20. The two ends of the connecting pipe 29 respectively pass through the two opposite side walls of the planar connecting plate 12.

[0045] like Figure 7 As shown, the main function of the connecting pipe 29 is to facilitate the water pipe or line pipe to pass from one wall panel assembly 3 to another wall panel assembly 3. The connecting pipe 29 can be flexibly arranged from top to bottom according to the use requirements.

[0046] A further optimized solution is that the floor frame assembly includes a lower floor frame 4 and an upper floor frame 5. The upper floor frame 5 is detachably connected to the top of the lower floor frame 4 by bolts. The inner edges of the top surface of the lower floor frame 4 and the inner edges of the bottom surface of the upper floor frame 5 are respectively provided with first grooves 17. Bosses 16 are respectively fixedly connected to the side walls of the floor slab 7, and the bosses 16 are adapted to the first grooves 17.

[0047] A further optimized solution is that a plurality of first through grooves 10 are respectively opened on the side walls of the lower floor frame 4 and the upper floor frame 5, and the two ends of a plurality of first connecting beams 8 are respectively connected between the two first through grooves 10 by bolts, and a plurality of second through grooves 19 are horizontally opened on the two opposite side walls of the first connecting beam 8, and the two ends of the second connecting beam 9 are respectively connected between a second through groove 19 and a first through groove 10 by bolts.

[0048] For example Figure 4 In the layout structure shown in the figure, the first through slot 10 and the second through slot 19 are opened at the corresponding positions of the side walls of the lower floor frame 4 and the upper floor frame 5 and the corresponding positions of the first connecting beam 8 during the design stage. During the construction process, the operator first uses the threaded ends of several bolts to pass through the first through slot 10 and connect to the two ends of the first connecting beam 8, and the heads of the bolts fit on the lower floor frame 4, and tighten the bolts to make the first connecting beam 8 as shown in the figure. Figure 5 As shown, it is fixed in the lower floor frame 4 and overlapped with the T-shaped connecting plate 13 at the rear of the base 1 and the top of the middle L-shaped connecting plate 2. Afterwards, the second connecting beam 9 is fixedly connected between the second through slot 19 on the first connecting beam 8 and the first through slot 10 on the right side by bolts, so that the second connecting beam 9 is as shown in FIG. Figure 5 The position shown is fixed and overlapped on the middle L-shaped connecting plate 2 and the right T-shaped connecting plate 13.

[0049] According to a further optimized solution, second grooves 18 are respectively provided at both ends of one side wall of the first connecting beam 8 and the second connecting beam 9 , and the second grooves 18 are provided corresponding to the bosses 16 .

[0050] like Figure 5 and Figure 6 As shown, the first connecting beam 8 and the second connecting beam 9 are fixedly connected in the lower floor frame 4, and after ensuring that the second grooves 18 on the first connecting beam 8 and the second connecting beam 9 are facing upward, a floor slab 7 of an adapted size is placed thereon, and the laying of the floor slab 7 in the lower floor frame 4 is completed by overlapping the boss 16 of the side wall of the floor slab 7 in the first groove 17 or the second groove 18.

[0051] Similarly, the first connecting beam 8 and the second connecting beam 9 are respectively connected in the upper floor frame 5, and then the top of the floor slab 7 is buckled downward to the top of the lower floor frame 4. During the process, ensure that the boss 16 is inserted into the first groove 17 and the second groove 18 of the upper floor frame 5 and the first connecting beam 8 and the second connecting beam 9 fixed thereon, and the construction of the middle floor is completed, forming a structure as shown in FIG. Figure 2 Status shown.

[0052] According to a further optimized solution, a plurality of inner plug-in blocks 27 are fixedly connected to the periphery of the inner wall panel 23 at intervals, and a plurality of outer plug-in blocks 26 are fixedly connected to the periphery of the outer wall panel 24 at intervals, and the plurality of outer plug-in blocks 26 are respectively fitted with the plurality of inner plug-in blocks 27;

[0053] A plurality of first slots 11 are respectively provided on the top edge of the base 1 and the bottom edge of the lower floor frame 4, and second slots 28 are respectively vertically provided on the side walls of the L-shaped connecting plate 2, the flat connecting plate 12 and the T-shaped connecting plate 13, and the outer plug-in block 26 and the inner plug-in block 27 are respectively inserted into the first slot 11 and the second slot 28.

[0054] like Figure 2 , Figure 4 and Figure 8-Figure 10 As shown, after the L-shaped connecting plate 2, the plane connecting plate 12 and the T-shaped connecting plate 13 are connected to the base 1, for the wall where the water pipe or line pipe needs to be installed, first lift the outer wall panel 24, align the outer plug-in blocks 26 on the left and right sides of the outer wall panel 24 with the second through grooves 19 on both sides, then lower the outer wall panel 24, make the outer plug-in blocks 26 slide down along the second through grooves 19, and make the outer wall panel 24 contact the base 1, so that the outer plug-in blocks 26 at the bottom are inserted into the first slot 11. Then, fix the water pipe or line pipe on the outer wall panel 24, and for the pipeline that needs to be extended to the left and right sides, the pipeline can be passed through the connecting pipe 29 to enter the adjacent wall. After the pipeline is installed and fixed, the inner wall panel 23 is hoisted in the same way, so that the outer plug-in blocks 26 and the inner plug-in blocks 27 fit in the first slot 11 and the second slot 28, and the fixing of the outer wall panel 24 and the inner wall panel 23 is completed. When the middle floor assembly is finally lowered, the outer insert block 26 and the inner insert block 27 at the top are inserted into the first slot 11 at the bottom of the lower floor frame 4 .

[0055] According to a further optimized solution, a sponge 25 is fixedly connected to one side of the inner wall panel 23 close to the outer wall panel 24, and the sponge 25 is in the cavity.

[0056] The main function of the sponge 25 is to fill the gap between the inner wall panel 23 and the outer wall panel 24 to improve the thermal insulation and sound insulation performance of the wall.

[0057] A further optimized solution is that the connecting parts between the base 1 and the planar connecting plate 12 include two groups of connecting columns 6 vertically fixedly connected to the top surface of the base 1, and sockets 22 are respectively provided at both ends of the two groups of load-bearing columns 20. The sockets 22 pass through the top and bottom surfaces of the planar connecting plate 12. The two groups of connecting columns 6 on the base 1 are respectively inserted into the two sockets 22 at the bottom of the planar connecting plate 12, and the connecting columns 6 and the sockets 22 are fixedly connected by bolts.

[0058] Further optimization scheme, such as Figure 2-Figure 4 As shown, since three groups of load-bearing columns 20 are respectively arranged in the L-shaped connecting plate 2 and the T-shaped connecting plate 13, and three groups of sockets are respectively arranged at the top and the bottom thereof, correspondingly, three groups of connecting columns 6 are respectively arranged at the bottom of the base 1 and the lower floor frame 4, so as to facilitate the connection between each connecting plate and the base 1.

[0059] Similarly, if Figure 2 As shown, the top of the upper floor frame 5 is also fixedly connected with a connecting column 6 according to design requirements to facilitate continued upward construction.

[0060] Further optimization scheme, the four columns of the connecting column 6 are respectively provided with a plurality of first threaded holes 14, which can be realized by welding threaded sleeves on the inner side of the connecting column 6. The side walls of the L-shaped connecting plate 2, the plane connecting plate 12 and the T-shaped connecting plate 13 are respectively provided with a plurality of second threaded holes 15, which can be realized by fixing and embedding threaded sleeves on the side walls of the load-bearing column 20, one end of the threaded sleeve is flush with the side wall of the jack 22, and the other end is flush with the outer wall of the corresponding connecting plate. The operator fixes the connecting plate by tightening the bolts into the second threaded holes 15 and the first threaded holes 14.

[0061] Embodiment 2:

[0062] The only difference between this embodiment and the first embodiment is that through holes (not shown in the figure) are respectively opened on the lower floor frame 4 and the upper floor frame 5.

[0063] When the water pipes or circuit pipes in the outer wall panel 24 need to be extended upward or downward to another floor, since the outer plug-in blocks 26 and the inner plug-in blocks 27 are arranged at intervals, the pipes can enter the wall panel assembly 3 of the upper or lower layer through the gaps between two adjacent outer plug-in blocks 26 and two adjacent inner plug-in blocks 27 and the through holes.

[0065] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
