Description

Technical Field

[0001] The invention belongs to the field of building structure vibration control, and in particular relates to a multi-directional torsion tension and compression shock absorption control and protection device. Background Art

[0002] Earthquake disasters are sudden and destructive, and seriously threaten the safety of human life and property. Nearly a thousand destructive earthquakes occur in the world every year. A major earthquake can cause economic losses of hundreds of billions of dollars and lead to the death or serious disability of hundreds of thousands of people. my country is located in the two most active seismic belts in the world and is one of the countries most seriously affected by earthquake disasters. The casualties caused by earthquakes rank first in the world, and the economic losses are also very huge. The massive destruction and collapse of buildings in earthquakes are the direct causes of earthquake disasters. When an earthquake occurs, the ground vibration causes the seismic response of the structure. For building structures with foundations fixed to the ground, the response is amplified layer by layer from bottom to top along the height. Due to the excessive seismic response (acceleration, velocity or displacement) of a certain part of the structure, the main load-bearing structure is severely damaged or even collapsed; or although the main structure is not damaged, the building finishes, decoration or other non-structural accessories are damaged, resulting in serious losses; or the damage of expensive indoor instruments and equipment leads to serious losses or secondary disasters. In order to avoid the occurrence of the above disasters, people must control the seismic response of the structural system and eliminate the "amplifier" effect of the structural system. The structural energy dissipation and vibration reduction technology is to design some non-load-bearing components of the structure (such as shear walls, connectors, etc.) into energy dissipation rods, or install energy dissipation devices in certain parts of the structure (interlayer space, nodes, joints, etc.). In the case of small winds or small earthquakes, these energy dissipation rods (or energy dissipation devices) and the structure itself have sufficient lateral stiffness to meet the use requirements, and the structure is in an elastic state; when a large earthquake or strong wind occurs, as the lateral deformation of the structure increases, the energy dissipation components or energy dissipation devices start to work first, produce large damping, consume a large amount of seismic or wind vibration energy input to the structure, and convert the kinetic energy or elastic potential energy of the structure into heat energy and other forms of dissipation, quickly attenuate the seismic or wind vibration response of the structure (displacement, velocity, acceleration, etc.), so that the main structure avoids obvious inelastic state, and protects the main structure and components from damage in strong earthquakes or strong winds. Because the external energy transmitted to the building structure by earthquakes and other reasons is the source of structural vibration, setting up energy dissipation devices in the structure and increasing energy dissipation will reduce the vibration response of the structure. The restrained concrete of the buckling-resistant energy-absorbing components currently under research and development is easily crushed and loses its restraint and buckling-resistant function, resulting in a significant reduction in its energy dissipation capacity. Therefore, the energy dissipation devices that resist vibration need to be upgraded and renovated. Summary of the invention

It not only ensures that the nodes have sufficient stiffness, but also changes the poor seismic resistance and energy dissipation characteristics of the connection nodes. The present invention has the characteristics of strong damping capacity, good fatigue resistance, low maintenance cost and strong seismic resistance. The present invention ensures that the connection is sufficiently stable and at the same time improves the seismic resistance, can effectively control the earthquake response of the building, and is conducive to promoting the development of building structures with poor seismic resistance, manufacturing process and energy dissipation improvement. At the same time, as a protective measure when an earthquake occurs, the low cost is a significant advantage of the present invention.

When vibration occurs and torsion occurs, the torsional tensile and compressive shock-absorbing main board will undergo a slight twist and then shear the reinforced connecting shear energy dissipation rivets to dissipate energy to achieve a primary shock-absorbing effect. Once the vibration occurs and torsion occurs and the limit shear force of the reinforced connecting shear energy dissipation rivets is reached, the torsional tensile and compressive shock-absorbing main board will shear damage the reinforced connecting shear energy dissipation rivets, and then the torsional tensile and compressive shock-absorbing main board will extrude the torsional extrusion setting soft board to dissipate energy to achieve a secondary shock-absorbing effect. At the same time, the torsional shock-absorbing ribs on the torsional tensile and compressive shock-absorbing main board will dissipate energy again to jointly resist the generated torsional vibration.

In the structure of the multi-directional torsion tension and compression shock absorption control and protection structure, a plurality of connecting screw holes 2 are arranged on the outer ring of the connecting plate layer 1, and the connecting screw holes 2 and the installation screw holes 4 are used to connect with an object with the device of the present invention installed.

A torsional extrusion setting soft board 7 is provided between adjacent torsional tension and compression shock-absorbing main boards 8 and torsional tension and compression shock-absorbing main boards 8. The torsional extrusion setting soft board 7 is provided close to the connecting plate layer 1, and a plurality of fixed through holes 9 are provided on the torsional extrusion setting soft board 7. A plurality of fixed connecting members 13 are provided to pass through the fixed through holes 9 to fix the connecting plate layer 1 and the torsional extrusion setting soft board 7. A built-in tension and compression buffer layer 15 is provided in the internal cavity of the structure surrounded by the connecting plate layer 1, the annular connecting plate ring 5 and the side fixed sealing plate 16 with holes, and a plurality of mounting screw holes 4 are provided on the outer ring of the fixed additional plate layer 3.

[0026] The torsion extrusion setting soft plate 7, the torsion tension and compression shock-absorbing main plate 8 and the reinforcement connection shear energy dissipation rivet 14 are made of low yield point steel plates determined according to design requirements.

[0027] The built-in tension and compression buffer layer 15 is made of a material with shock absorption and elasticity capabilities.

[0028] The cross-sectional diameter of the torsional tension and compression force transmission beam 6 and the diameter of the reserved hole 17 for the force transmission beam on the side fixed sealing plate 16 with holes are matched and set.

[0029] The fixed connection member 13 is made of manganese steel.

[0030] The torsion tension and compression force transmission beam 6 is made of steel material.

[0031] The device composed of the torsional tension and compression force transmission beam 6 and the torsional tension and compression shock-absorbing main board 8 is a prefabricated component and ensures that the torsional tension and compression force transmission beam 6 and the torsional tension and compression shock-absorbing main board 8 have sufficient connection strength.

[0032] The reinforced connection shear energy dissipation rivet 14 is used for the fixed connection between the torsional tension and compression shock-absorbing main board 8 and the connection setting plate layer 1. When vibration occurs and torsion is generated, the torsional tension and compression shock-absorbing main board 8 will undergo a slight twist and then shear energy dissipation on the reinforced connection shear energy dissipation rivet 14 to achieve a primary shock-absorbing effect.

At the same time, the torsional shock-absorbing setting ribs 11 on the torsional tension and compression shock-absorbing main board 8 will perform energy dissipation again to jointly resist the generated torsional vibration.

[0033] When relative tension and compression occur, the torsional tension and compression force transmission beam can drive the torsional tension and compression shock-absorbing mainboard to squeeze the built-in tension and compression buffer layer to consume energy. At the same time, the reinforced connecting shear energy dissipation rivets are used to fix the connection between the torsional tension and compression shock-absorbing mainboard and the connecting setting plate layer. When vibration occurs and torsion occurs, the torsional tension and compression shock-absorbing mainboard will undergo a slight twist and then shear the reinforced connecting shear energy dissipation rivets to consume energy to achieve a primary shock-absorbing effect. Once the vibration occurs and torsion occurs and reaches the limit shear force of the reinforced connecting shear energy dissipation rivets, the torsional tension and compression shock-absorbing mainboard will shear damage the reinforced connecting shear energy dissipation rivets. Then the torsional tension and compression shock-absorbing mainboard will squeeze the torsional extrusion setting soft board to consume energy to achieve a secondary shock-absorbing effect. At the same time, the torsional shock-absorbing ribs on the torsional tension and compression shock-absorbing mainboard will consume energy again to jointly resist the generated torsional vibration.

[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
