[0041] For better explaining the present utility model for easy understanding, the present utility model will be described in detail below in conjunction with the accompanying drawings through specific implementation manners. Among them, the orientation nouns such as "upper", "lower",... mentioned in this article are based onFigure 1 is oriented for reference.

[0042] Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present invention can be more clearly and thoroughly understood, and the scope of the present invention can be fully conveyed to those skilled in the art.

[0043] As Figures 1 - 10 shown, the present invention provides a flipping floor for a prefabricated building. Among them, the prefabricated building includes a first box body 100 and a second box body 200 connected to each other. The second box body 200 can slide relative to the first box body 100 to expand the internal space of the prefabricated building. The flipping floor is installed in the second box body 200. When the second box body 200 shrinks into the first box body 100, the flipping floor folds and shrinks. After the second box body 200 extends, the flipping floor is laid flat in the second box body 200 and serves as the floor of the second box body 200. A plurality of flipping floors can be longitudinally arranged at the bottom of the second box body 200. Further, the flipping floor includes a first floor 1 and a second floor 2 hinged to each other by a long row of hinges. The first floor 1 is hinged to the side of the first box body 100 by a long row of hinges. The second floor 2 is slidably connected to the second box body 200. When the first floor 1 rotates around the hinge point with the first box body 100, the whole flipping floor moves between a first state and a second state. In the first state, the first floor 1 and the second floor 2 are laid flat on the bottom of the second box body 200 and serve as the floor of the second box body 200 for bearing weight and closing the bottom of the second box body 200; in the first state, the first floor 1 rotates, driving the second floor 2 to slide and rotate synchronously, and the flipping floor folds and shrinks until it moves to the second state. In the second state, the first floor 1 and the second floor 2 both rotate into the first box body 100, and the bottom surfaces of the first floor 1 and the second floor 2 are mutually attached. By dividing the whole floor module into the first floor 1 and the second floor 2 hinged to each other, the present invention effectively reduces the flipping radius during the flipping process, improves the flexibility of flipping, and reduces the need for internal space during the flipping of the floor; during the process of the flipping floor folding and flipping, it is supported by the hinge point of the first floor 1 and the first box body 100 and the sliding connection point of the second floor 2 and the second box body 200, and the first floor 1 and the second floor 2 are folded in half, reducing the flipping height. Driving the rotation of the first floor 1 can reduce the driving force and connection mechanism required for flipping, and reduce the space occupied by the driving device and the connection structure.

[0044] As Figure 5As shown in the figure, support square steel tubes 3 are arranged in pairs at the bottom of the first box body 100. In the first state, the bottom surfaces of the first floor 1 and the second floor 2 are both in contact with the square steel tubes. After the second box body 200 is unfolded, each second floor 2 is supported by the support square steel tubes 3 arranged in pairs for load-bearing. A first fixing groove is arranged at the bottom of the first box body 100, and a second fixing groove 201 is arranged at the bottom of the second box body 200. The first fixing groove and the second fixing groove 201 are preferably fixing channel steels. The two ends of the support square steel tube 3 are detachably connected to the first fixing groove and the second fixing groove 201 in one-to-one correspondence. Specifically, first pin holes are provided in the parts of the support square steel tube 3 located in the first fixing groove and the second fixing groove 201, and second pin holes are correspondingly provided in the first fixing groove and the second fixing groove 201. The first pin holes and the second pin holes on the same side are connected by square steel tube pins. Using the square steel tube pins to fix the support square steel tube 3 in the corresponding fixing groove can not only prevent the support square steel tube 3 from moving, but also facilitate disassembly and assembly. In addition, because the steel structure support square steel tube 3 is detachable, when the ground is uneven, pads with the same thickness can be placed on the supporting surface of the support square steel tube 3 to ensure the horizontality of the first floor 1 and the second floor 2.

[0045] Furthermore, as Figures 4 - 7 shown in the figure, sliding wheels 21 are arranged in pairs at the bottom of the second floor 2. The sliding wheels 21 correspond to the positions of the support square steel tubes 3 one by one. During the flipping process of the first floor 1, the sliding wheels 21 of the second floor 2 are driven to slide on the support square steel tubes 3, reducing the resistance of the movement of the second floor 2. In the first state, the sliding wheels 21 are located in the second fixing groove 201. The second fixing groove 201 provides a clearance position for the sliding wheels 21 to ensure that in the first state, both the first floor 1 and the second floor 2 are in complete contact with the support square steel tubes 3, and the first floor 1 and the second floor 2 are in the same plane. A wedge-shaped block 31 is arranged at one end of the support square steel tube 3 located in the second fixing groove 201. The wedge-shaped block 31 serves as a sliding track for the sliding wheels 21, facilitating the sliding wheels 21 to slide out of the second fixing groove 201.

[0046] As Figure 4 shown in the figure, both the first floor 1 and the second floor 2 include a cement fiber board 11 and a metal frame 12 stacked in sequence. Specifically, the main structural parts of the first floor 1 and the second floor 2 are steel, with the material being Q355. The top surface layer is a cement fiber board 11. The overall weight is relatively large and the rigidity is relatively large, which can meet a relatively large load. The flipping structure of the present invention is applicable to the flipping of steel structure floors with relatively large weights. To ensure the flatness of the top surface of the cement fiber board 11, the long-row hinges between the first floor 1 and the first box body 100 are vertically installed on the metal frame 12, and the highest point of the hinge is lower than the height of the cement fiber board 11.

[0047] As Figures 4 - 6As shown, in the first floor 1, the width of the cement fiber board 11 is less than the width of the metal frame 12; in the second floor 2, the width of the cement fiber board 11 is greater than the width of the metal frame 12. In the first state, the cement fiber board 11 of the second floor 2 overlaps on the metal frame 12 of the first floor 1, effectively ensuring the airtightness of the flip floor. In the first state, there is a gap 13 between the cement fiber board 11 of the second floor 2 and the cement fiber board 11 of the first floor 1. Specifically, to ensure that the flipping angle of the ground is greater than 120 degrees, a 30-mm gap is provided between the cement fiber board 11 of the first floor 1 and the cement fiber board 11 of the second floor 2. The long-row hinge between the first floor 1 and the second floor 2 is installed on the bottom surface of the metal frames 12 of the two floors, and the center of the rotation axis of the hinge is located in the middle of the gap 13.

[0048] As Figure 9 shown, the flip floor further includes a driving mechanism 4. The driving mechanism 4 is installed on the top of the first box body 100. The driving mechanism 4 is connected to the first floor 1 and drives the first floor 1 to rotate from the first state to the vertical state. The driving mechanism 4 is preferably an electric hoist. The electric hoist is fixed to the top of the first box body 100 through a lifting ring. The chain of the electric hoist is connected to the metal frame 12 of the first floor 1 through another lifting ring and is used to lift and flip the first floor 1. Specifically, when installing the electric hoist and connecting the chain to the floor, the electric hoist pulls the floor to the 90-degree position. Manual assistance is used to push the floor outward. The electric hoist slowly lowers. When the sliding wheel 21 of the flip floor is about to contact the supporting square tube 3, while manually assisting to push the second point outward, the electric hoist lowers, so that the sliding wheel 21 falls onto the supporting square tube 3. The electric hoist lowers, and the flip floor slides to the flat position and stops. The semi-automatic method is adopted to realize the expansion of the floor, reducing the manufacturing cost.

[0049] As Figure 8 and Figure 10 shown, the flip floor further includes a support frame 5. The support frame 5 includes a base 51, a first support column 52, and a second support column 53. The base 51 is arranged in the first box body 100. Both the first support column 52 and the second support column 53 are detachably connected to the base 51. A square frame for installing the first support column 52 and the second support column 53 is welded on the base 51, facilitating the disassembly and assembly of the first support column 52 and the second support column 53 and replacing the first support column 52 and the second support column 53 with different heights according to the height of the floor. In the second state, the first floor 1 abuts against the first support column 52 and the second support column 53, and the flipped floor is supported by the support frame 5.
