The floor unit 3 includes an extension floor 32 and a fixed floor 31.

The extension rail 21 and the extension base plate 32 are hinged to each other, and a second linkage 42 is provided. The second link mechanism 42 includes a second upper link 4201, a second joint link 4202, a second middle link 4203, a second lower link 4205, and a second auxiliary link 4204; the second auxiliary link 4204 is hinged to the second upper link 4201 and the extension rail 21, respectively; the second joint link 4202 is hinged to the extension rail 21 at the middle, and both ends are hinged to the second upper link 4201 and the second middle link 4203, respectively. The extending base plate 32 is provided with a second fixed shaft, and the second lower link 4205 is hinged with the second middle link 4203 and the second fixed shaft, respectively.

The extension bottom plate 32 and the fixed bottom plate 31 are hinged with each other, and a third link mechanism 43 is arranged. The third link mechanism 43 includes a third upper link 4301 and a third lower link 4302 connected to each other. The lower part of the third upper connecting rod 4301 is provided with a first fixed shaft. The third link mechanism 43 is hinged between the middle part of the extending bottom plate 32 and the fixed bottom plate 31 and is used for driving the extending bottom plate 32 to extend or fold relative to the fixed bottom plate 31; meanwhile, the extension base plate 32 is positioned in the unfolded or folded state, and the stability of the position state of the extension base plate 32 with respect to the fixed base plate 31 is ensured.

The fixed base plate 31 is a horizontally disposed regular octagon, and eight extending rails 21 are rotatably connected to each side of the fixed base plate 31. The bottom edge of the extension rail 21 and the top edge of the extension base plate 32 are vertically and fixedly connected with each other, and the vertical state between the extension rail 21 and the extension base plate 32 is kept unchanged in each state of the system folding or unfolding.

A plurality of groups of stretching mechanisms consisting of the ceiling unit 1, the railing unit 2, the bottom plate unit 3 and the connecting device 4 are uniformly distributed by taking the fixed bottom plate 31 as the center, and all groups of stretching mechanisms are synchronously unfolded to form an approximately cylindrical building structure; or each set of stretching mechanisms is synchronously folded by taking the fixed bottom plate 31 as the center to form a cylindrical folding structure taking the fixed bottom plate 31 as the bottom surface.

When the folding system is folded and contracted, each extending bottom plate 32 is upwards and inwards recovered, the left supplement beam and the right supplement beam are simultaneously driven, the connecting elements enable the horizontal left supplement beam and the horizontal right supplement beam to be inwards bent along the connecting edges when the left supplement beam and the right supplement beam are unfolded, and the left supplement beam and the right supplement beam are inwards folded and extend into the cylindrical body surrounded by the extending bottom plates 32.

A sinking bottom plate 6 is arranged in the middle of the fixed bottom plate 31, and the sinking bottom plate 6 forms a depression in the middle of the fixed bottom plate 31.

The bottom of the hydraulic cylinder 5 is connected with the lower part of the sinking bottom plate 6, and the piston rod at the upper part of the hydraulic cylinder 5 is connected with the first fixed shaft of the third connecting rod mechanism 43. The hydraulic cylinder 5 is composed of a cylinder barrel, a cylinder cover, a piston rod, a sealing device, a buffering device and an exhaust device, and is used for converting hydraulic energy into mechanical energy and realizing linear reciprocating motion of the mechanism. The device has the advantages that a speed reducing device is omitted, no transmission gap exists, and the motion is stable. The piston rod of the hydraulic cylinder 5 moves relative to the cylinder barrel and drives the first fixed shaft to move, so that the third link mechanism 43 moves, and the displacement of the third link mechanism 43 further moves the extension bottom plate 32. This achieves: the hydraulic cylinder 5 is extended to fold the extension bottom plate 32 inwards relative to the sinking bottom plate 6 and the fixed bottom plate 31; the hydraulic cylinder 5 is shortened causing the spreader baseplate 32 to expand outwardly relative to the sinker baseplate 6 and the fixed baseplate 31.

The extension rail 21 has a polygonal frame structure consisting of a lower rectangular frame and an upper trapezoidal frame, the lower rectangular frame is a stable rectangular frame, and the upper trapezoidal frame is a trapezoidal frame without interfering with the upper rectangular frame at the top when the extension rail is retracted. The fixed bottom plate 31 is a regular polygon frame structure, and the number of sides of the fixed bottom plate 31 is the same as the number of groups of the stretching mechanisms.

The first lower supporting beam 1201 moves outwards, so that the second slider 4103 drives the first slider 4101 to slide outwards in the first hollow track, and then pulls the first upper supporting beam 1101 to move upwards, when the first lower supporting beam 1201 slides outwards relative to the second lower supporting beam 1202 to a certain distance, the first telescopic beam 1301 connected to the end of the first lower supporting beam 1201 drives the second telescopic beam 1302 and the third telescopic beam 1303 to move outwards, and pulls the second lower supporting beam 1202 to move outwards relative to the third lower supporting beam 1203 through the fixing snap ring, so that the fourth telescopic beam 1304 and the fifth telescopic beam 1305 also extend outwards. Finally, to the extent that the first 1201, second 1202 and third 1203 lower support beams are extended to the longest extent and the first 1101 and second 1102 upper support beams are fully extended, the roof structure is fully unfolded.
