[0016] Preferably, the adjacent sides of the two reinforcement frames at the left and right ends are fixedly connected with connecting sleeves, and the front and rear sides of the top of the arch frame are sleeved inside the connecting sleeves.

[0017] Preferably, the separated sides of the two reinforcement frames at the left and right ends are connected with support feet through a damping shaft, and the top ends of the support feet abut against the inner periphery of the top plate.

[0018] Preferably, adjacent sides of the two cross beam portions are connected via an interference fit cross beam connecting I-shaped piece.

[0019] Working principle: When constructing and splicing the roof, first unfold the folded bottom plate and sub-plates, pull out the chassis connection I-shaped piece located inside the connection groove, pull out the multiple fixing plug-ins plugged into the folded bottom plate and the side of the sub-plate, so as to release the folding limit, then unfold the top plates on both sides of the bottom plate by rotating, insert the fixing plug-ins into the sockets on the top side of the sub-plates, then align them with the openings on the side of the sub-plates, insert the chassis connection I-shaped piece through the bottom plate, the sub-plates on both sides of the bottom plate, and the plugged fixing plug-ins, so that the bottom plate and the sub-plates are stabilized, then The connecting frame is plugged into the openings at both ends of the connecting groove, and the top of the connecting frame is placed on the top side of the sub-plate to provide a connection point. Then, the hoops on the front and rear sides of the reinforcement beam are plugged into the top of the connecting frame for positioning and installation, and are tightened and fixed with bolts to prevent the reinforcement beam from shifting. The installation of reinforcement frame one and reinforcement frame two begins. Reinforcement frame two is installed first in order from the inside to the outside. A group of reinforcement frame two at one end is installed with bolts first, and then the arch frame is aligned with the connecting sleeve on reinforcement frame two for plugging, followed by the reinforcement frame at the other end. The second reinforcement frame is installed, and the connecting sleeve is also aligned for plugging. When the second reinforcement frame is installed, the arch frame is fixed. Finally, the reinforcement frame one is installed on the periphery of the second reinforcement frame by bolts, thereby completing the installation of the first reinforcement frame and the second reinforcement frame. The installation of the buffer head and the buffer frame as the buffer shock absorbing structure begins. The connecting plug fixed to the bottom side of the connecting plate of the buffer head is aligned with the socket on the top side of the first reinforcement frame and the second reinforcement frame for plugging and fixing. Then the bite piece is inserted into the insertion openings on both sides of the first reinforcement frame and the second reinforcement frame, and the reinforcement frame is aligned with the first reinforcement frame and the second reinforcement frame. The connecting plug inside the reinforcement frame 2 is limited, the two engaging parts are attracted to each other with opposite sexes and fixed by magnets, the buffer frame is installed and fixed on the arch frame with bolts, the installation of the buffer structure is completed, and the final finishing work is carried out. The two top plates are connected by I-shaped pieces with cross beams to splice and assemble the cross beam parts to form a roof structure. The top plate is then covered on the top side of the reinforcement frame 1 and the reinforcement frame 2, and the card slots on the inner wall of the top plate are aligned with the top of the support plug for plugging, and the bottom side of the top plate and the bottom side of the bottom plate are at the same level to complete the splicing and fixation. When subjected to vibration and impact, the supporting plug connected to the top plate will be subjected to the vibration force synchronously, and the force will be transmitted to the spring damping shaft and absorbed by the spring damping shaft. The vibration causes the abutment connected to the crossbeam to apply force to the contact rack on the bottom side, thereby causing the contact rack to mesh with the buffer gear connected thereto. The buffer gear utilizes the characteristics of the clockwork spring to rotate the buffer gear connected thereto. After applying force to the clockwork spring, the clockwork spring will be wound up to convert the force generated by the vibration impact. Due to the meshing relationship between the buffer gear and the contact rack, the clockwork spring drives the buffer gear to be subjected to the friction generated by the meshing of the contact rack during the resetting process, thereby slowing down the resetting of the clockwork spring and avoiding the rebound reaction force generated by resetting too quickly.

[0020] The present invention provides a shock-absorbing roof structure for a building, which has the following beneficial effects:

[0021] 1. The present invention can reduce the floor space occupied during transportation and realize foldable transportation through the foldable roof chassis structure. The connecting structure for fixing the chassis can be stored together and fixed after storage by the connecting structure to prevent the storage structure from dispersing, thereby stabilizing the integrity of the structure during transportation.

[0022] 2. The present invention reduces the impact of vibration on the connection by reinforcing the chassis structure used for connection, thereby improving stability, reducing shaking, and concentrating the vibration force on the shock-absorbing structure to avoid shaking of loose parts. It helps to transmit the vibration force to the shock-absorbing structure to avoid structural damage caused by shaking of loose parts.

[0023] 3. The present invention uses a conical buffer structure corresponding to the inner circumferential planes of the two top plates, so that when the top plates are impacted and vibrated, the impact and vibration received can be stably shared, thereby increasing the ability to absorb the force generated by the vibration.
