[0034] In order to facilitate understanding of the above technical solutions of the present invention, the above technical solutions of the present invention are described in detail below through specific usage methods.

[0035] In specific use, according to the present invention:

[0036] The beam-column connection structure is pre-embedded with a steel connector 15 when the column component 14 is manufactured, and an ear plate 16 is welded on the steel connector 15. When the beam component 2 is manufactured, a box-shaped steel connector 1 is pre-embedded, and the stress-bearing steel bars 3 in the beam are reliably connected to the steel connector 1 by welding. A connecting steel plate 4 is welded to each of the four corners of the steel connector 1, and then a steel cylinder 5 is welded. When preparing for installation, the steel plate 3 22 is reliably welded to the steel connector 6, a bolt 13 is pre-placed in the steel connector 6, and a spring 2 23 and a spring 3 24 are placed in the steel connector 6. After completion, the steel connector 6 is inserted into the steel In the cylinder 5, a steel plate 7 is placed inside the steel connecting part 6, and a clamp plate 12 and an inner steel cylinder 8 are welded on both sides of the steel plate 7. A spring 9 is placed outside the inner steel cylinder 8, and the spring 9 is welded to the outer steel cylinder 10 and the outer steel plate 11. The spring 9 is inserted into the outer steel cylinder 10, and the outer steel plate 11 is pressed down by adjusting the bolt 13 so that the spring 9 has elastic potential energy, and then the pull rod 20 is passed through the steel plate 3 22, the spring 23, the steel cylinder 5, the spring 3 24, and the steel plate 2 18, and the pull rod 20 is connected to the steel ear plate 16 through the steel bayonet 17, and the spring is adjusted by adjusting the nut 19. 23. Spring 3 24 has elastic potential energy. By adjusting spring 19, spring 19 presses steel plate 17, and steel plate 17 presses steel connector 1. The arrangement of inner steel cylinder 8 and outer steel cylinder 10 can ensure that spring 19 does not move when subjected to force, and the force transmission is stable, so that the beam-column connection structure exerts force in the up, down, left and right directions. These forces must meet the bearing capacity of the beam-column connection structure. When the up, down, left and right forces are generated by earthquakes and other situations, spring 19 can shrink and deform again. When the external force is removed, spring 19 returns to its original state, thereby achieving the effect of energy dissipation and earthquake resistance. In the horizontal direction of the column-beam-column connection structure, On the upper side, by adjusting the nut 19, the steel plate 2 18 presses down the spring 3 24, the spring 3 24 presses down the steel cylinder 5, the steel cylinder 5 presses down the spring 23, the spring 23 is limited and constrained by the steel plate 3 22, and the steel plate 3 22 is limited and constrained by the pull rod 20, so that the spring 23 and the spring 3 24 have the ability to resist lateral tension, and at the same time, when subjected to forces generated by earthquakes and the like, the spring 23 and the spring 3 24 can shrink and deform again, thereby achieving the effect of energy dissipation and earthquake resistance. At the same time, this structure can realize the fully mechanized installation of assembled beams and columns, and when a component is damaged, it can be replaced.

[0037] (2) Beam-slab connection structure: When the beam member 2 is manufactured, embedded bolts 25 are placed as the main components of the beam-slab connection structure. When the prefabricated plate 38 is manufactured, embedded steel cylinders 21 and embedded fixings 32 are used as the main load-bearing components of the beam-slab connection structure. Steel plate 4 28 is welded on the lower steel plate 26, and steel plate 7 35 is welded on the top of steel plate 4 28. Steel plate 7 35 is connected to steel plate 6 33 through hinges 34. Spring 5 36 is fixed to steel plate 4 28, and then the other end of spring 5 36 is fixed to steel plate 6 33. Clamping plates 27 are welded on both sides of the lower steel plate 26, and clamping plates 31 are welded on both sides of steel plate 5 30. Clamping plates 27 are placed inside steel plate 4 28. The embedded steel cylinder 21 in the prefabricated plate 38 is inserted into the embedded bolts 25. The plate is pressed down on steel plate 6 33 by adjusting nut 2 37, and steel plate 6 33 compresses the spring. The spring 36 is made to have elastic potential energy in the vertical direction. At the same time, when a force in the horizontal direction is generated by an earthquake or the like, the spring 36 can shrink and deform again. When the external force is removed, the spring 36 returns to its original state. In the vertical direction, the spring 29 has elastic potential energy. When a force in the vertical direction is generated by an earthquake or the like, the spring 29 can shrink and deform again. When the external force is removed, the spring 29 returns to its original state, thereby achieving the effect of energy consumption and earthquake resistance. At the same time, this structure can realize the fully mechanized installation of assembled beams and columns, and when a component is damaged, it can be replaced.

[0038] To sum up, with the help of the above-mentioned technical scheme of the present invention, by adopting steel plates, round steel cylinders, springs, ear plates, pull rods, connectors and other components, through pre-embedded connectors, setting connecting devices, adding elastic potential energy to the springs arranged in the device, so that the entire structure can have the ability to dissipate energy and resist earthquakes in all directions, and realize the fully mechanized construction of prefabricated building columns, beams, plates and other structures. Under normal use, they have good bearing capacity. When external forces such as earthquakes occur, they can dissipate energy at the column-beam connection and the beam-slab connection for the forces transmitted in all directions, thereby achieving higher earthquake resistance. At the same time, when a component is damaged, it can be replaced, or the building can be demolished, and the component can be recycled again.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
