Description

Technical Field

[0001] The present invention relates to the field of prefabricated buildings, and in particular to a frame-variable prefabricated building. Background Art

[0002] Prefabricated buildings generally use prefabricated concrete structures, steel structures, modern wooden structures, etc. Standard structural parts are manufactured in batches and sets in factories, and then the prefabricated house components are transported to the construction site for assembly.

[0003] For prefabricated buildings with many floors, the foundation typically requires the same excavation and pouring techniques as traditional construction, and even the load-bearing columns require traditional methods. Non-load-bearing walls can be installed using an assembly method, with the joints finally cast together to form a single piece, saving construction time. For low-rise buildings, prefabricated construction offers greater flexibility, even eliminating the need for pouring foundations, and allowing for complete assembly of prefabricated factory components.

[0004] Compared with traditional buildings, prefabricated buildings have a wider range of applications. For some low-rise prefabricated buildings without foundations, in order to increase reuse, they need to be dismantled and the structure changed from time to time, such as exhibition galleries, exhibition halls, and viewing buildings. Traditional prefabricated buildings use a fully assembled structure, which requires the entire building to be dismantled and then useful structures to be combined together according to the required design. Disassembly and assembly are relatively time-consuming and labor-intensive. Summary of the Invention

DETAILED DESCRIPTION

[0028] Example 1:

[0029] like Figure 1-10 In the invention, a frame-variable prefabricated building includes multiple unit frames 1, which form a closed-loop structure connected end to end. The unit frame 1 includes a frame body 101, and multiple hinged ear seats 103 are provided at both ends of the frame body 101. Adjacent unit frames 1 are hingedly connected. Exterior panels 102 are provided on both sides of the frame body 101, and end flange docking plates 104 are provided at the other two ends of the frame body 101. The closed-loop structure composed of multiple unit frames 1 is stacked in multiple layers through the end flange docking plates 104.

[0030] Since the unit frame 1 is hinged, the closed-loop structure can change its geometric shape. The closed-loop structure of the lower layer and the closed-loop structure of the upper layer can present different geometric shapes, which is more artistic.

[0031] The lower end face flange butt plate 104 of the lower layer can be installed on the ground by expansion screws, and the lower end face flange butt plate 104 of the upper layer and the upper end face flange butt plate 104 of the lower layer can be butted and installed by bolts.

[0032] Each frame 101 is an independent area, where the exterior panels 102 are installed. After the shape is determined, the floor is installed.

[0033] Due to the use of hinged and layered splicing, the geometric shapes of the upper and lower layers can be changed after the expansion bolts and butt bolts are removed, and they can be butt-jointed and installed again after adjustment.

[0034] In the preferred embodiment, the hinged positioning assembly 2 includes a first hinge 202 and a second hinge 203. The first hinge 202 is provided with a second latch portion 209, and the second hinge 203 is provided with a first latch portion 208. The first latch portion 208 and the second latch portion 209 are respectively inserted into the frame body 101 of the adjacent unit frame 1. The first hinge 202 is provided with an outer sleeve structure, and the second hinge 203 is provided with an inner sleeve structure. The outer sleeve structure and the inner sleeve structure are rotatably connected.

[0035] The articulated positioning assembly 2 is arranged near the upper and lower ends, and a main articulated column 210 is set in the middle. The main articulated column 210 has a relatively thick diameter and serves as the main force-bearing axis of multiple articulated ear seats 103 in the middle of the unit frame 1. The main articulated column 210 is a hollow tube, and the push-pull rod 201 passes through the middle.

[0036] In the preferred solution, a push-pull rod 201 is provided at the center of the rotating shaft of the articulated positioning assembly 2, and the push-pull rod 201 can move along the length direction. At least two spherical top balls 207 are sleeved on the push-pull rod 201. The side wall of the inner sleeve structure of the second hinge 203 is circumferentially provided with multiple notches 204 and V-shaped abutment parts 205. One end of the V-shaped abutment part 205 is deformably connected to the inner sleeve structure. The inner wall of the outer sleeve structure of the first hinge 202 is circumferentially provided with multiple grooves 206. The push-pull rod 201 moves along the length direction so that the spherical top ball 207 squeezes the V-shaped abutment part 205, and the free end of the V-shaped abutment part 205 is stuck in the groove 206.

[0037] The upper end of the push-pull rod 201 is threadedly connected to the limit block 211 as a limit and final force-bearing structure.

[0038] The slot 206 is a vertical slot, evenly distributed around the circumference. Initially, the free end of the V-shaped abutment portion 205 is received in the notch portion 204 to facilitate assembly and connection of the first hinge 202 and the second hinge 203. The push-pull rod 201 drives the spherical top bead 207 to squeeze the upper bevel of the V-shaped abutment portion 205 downward. At this time, the free end of the lower bevel of the V-shaped abutment portion 205 moves outward until the first spherical top bead 207 passes over, and the sharp corner of the V-shaped abutment portion 205 is stuck between the two spherical top beads 207. At this time, the free end of the V-shaped abutment portion 205 still extends a part and is stuck in the slot 206. The circumferential rotation of the second hinge 203 and the first hinge 202 is locked, that is, the angle between the two adjacent unit frames 1 is locked.

[0039] In the preferred embodiment, an anchoring device 3 is provided at the lower end of the frame 101, and the anchoring device 3 includes a main anchor 301 and a transition sleeve 302. The side wall of the transition sleeve 302 is provided with multiple through holes 303 along the circumference. A slidable movable block 305 is provided in the transition sleeve 302, and a plurality of deformable secondary anchors 304 are provided at one end of the movable block 305. The secondary anchors 304 are inserted into the through holes 303, and the other end of the movable block 305 is connected to the push-pull rod 201.

[0040] Initially, the secondary anchor 304 is received in the inner cavity of the transition sleeve 302, and its tip is received in the through hole 303. The main anchor 301 is inserted into the soil ground until the end face of the unit frame 1 is against the ground. At this time, the push-pull rod 201 is pushed down. When the push-pull rod 201 is pressed down, the movable block 305 moves down, pushing the secondary anchor 304 out. The through hole 303 is inserted into the soil horizontally or obliquely downward to form a claw shape, anchoring the ground.

[0041] In a preferred solution, adjacent V-shaped abutting portions 205 are staggered in the longitudinal direction of the push-pull rod 201 , and at least three spherical top beads 207 are arranged side by side. The three spherical top beads 207 clamp two adjacent V-shaped abutting portions 205 .

[0042] Due to the staggered positions in the height direction, the V-shaped abutment portion 205, the slot 206 and other corresponding structures can be arranged more densely in the circumferential direction, the angular gears of the first hinge 202 and the second hinge 203 are denser, the applicable working conditions are more flexible, and there are more locking points in the circumferential direction, and the angle locking is more stable.

[0043] In a preferred solution, the spherical top ball 207 is threadedly connected to the push-pull rod 201 .

[0044] The vertical height of each spherical top bead 207 can be adjusted to adapt to the height position of each oblique side of the V-shaped abutment portion 205 of the upper and lower hinged positioning components 2 .

[0045] In a preferred solution, the second hinged member 203 is provided with a threaded sleeve 212 , and the transition sleeve 302 is threadedly connected to the threaded sleeve 212 .

[0046] The main anchor 301 and the transition sleeve 302 are detachable, and the transition sleeve 302 and the second hinge 203 are also detachable, so the installation is more flexible. At the same time, when the secondary anchor 304 is assembled into the through hole 303, the main anchor 301 can be removed, which is convenient for operation.

[0047] In a preferred solution, the main anchor 301 is threadedly connected to the transition sleeve 302 , and the main anchor 301 is provided with a stopper 306 , which stops the movable block 305 .

[0048] In a preferred embodiment, a cable connecting ear nail 213 is provided at the lower end of the push-pull rod 201 , and a cable 4 is also provided. One end of the cable 4 is fixed to the ground through an anchoring portion 401 , and the other end of the cable 4 is connected to the cable connecting ear nail 213 .

[0049] The upper unit frame 1 can be tightened on the ground by using a cable 4 for auxiliary fixation.
