Description

A steel structure earthquake-proof building structure

Technical Field

The utility model relates to the technical field of steel structure earthquake resistance, in particular to a steel structure earthquake resistance building structure.

Background Art

With the increase in the number of buildings, the current structure is mainly composed of steel structural components. The lightweight characteristics of steel structures make the buildings themselves relatively light, and they are prone to collapse when facing the severe vibrations caused by earthquakes. Because the collapse speed is too fast, the people in the building cannot get time to evacuate, resulting in large losses to the people and property in the building. When a slight vibration occurs, the steel structure will not collapse, but the indoor working equipment and steel body will be damaged, posing a major safety hazard. Due to the high cost of steel structures, the maintenance and replacement costs are increased. The main materials of steel structures are steel beams, steel columns, and steel trusses, but steel is a combustible material. Compared with combustible materials such as concrete, steel structures have poor fire resistance when a fire occurs, which will cause the steel to lose strength and rigidity, thereby affecting the stability and safety of the building structure.

At present, the shock-absorbing structures of steel structures all improve the rigidity of the steel structures themselves so that they can resist vibrations through their own materials when small earthquakes occur. However, it is unrealistic and impossible to resist earthquakes through their own rigidity when the amplitude is large. Their shock-resistant ability is weak, the structure is large in size, and it is very inconvenient to use. They also require long-term maintenance and replacement, and are difficult to promote for use. In addition, the existing shock-absorbing structures of steel structures do not have the functions of corrosion and fire prevention, and need to be replaced in the event of a fire, which is costly.

The purpose of the utility model is to provide a steel structure earthquake-proof building structure, which solves the technical problems of weak earthquake resistance, large volume, no fire resistance, no rust resistance and high maintenance cost in the prior art, and achieves the technical effects of high earthquake resistance, small volume, fire resistance, corrosion resistance and low maintenance cost.

In order to achieve the above utility model purpose, the technical solution adopted by the utility model is:

The combination of the steel plate layer and the rubber layer can not only support the building, but also keep the building stable, and the structure can provide buffering and shock absorption functions at the same time. The setting of the memory metal in the middle drives the entire second earthquake-proof component to return to its initial position after an earthquake occurs. The setting of the elastic connector reduces the friction between the first earthquake-proof component and the second earthquake-proof component, so that the overall earthquake-proof structure has high coordination efficiency and high earthquake resistance. The setting of the protective layer increases the fire and corrosion resistance of the entire structure, so that the entire device will not be affected in the event of a fire, and does not require frequent maintenance and replacement.

The same parts are represented by the same figure marks. It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to the directions in the drawings, and the words "inside" and "outside" refer to the directions toward or away from the geometric center of a specific component, respectively.

As shown in Figures 1-7, a steel structure earthquake-proof building structure includes an upper positioning plate 2, an earthquake-proof support 1 and a lower positioning plate 3. The lower end of the upper positioning plate 2 is fixedly connected to the earthquake-proof support 1, and the lower end of the earthquake-proof support 1 is fixedly connected to the lower positioning plate 3. The earthquake-proof support 1 includes a first earthquake-proof component 6, a second earthquake-proof component 7 and an elastic connecting member 9. The first earthquake-proof component 6 is fixedly arranged at the middle position of the upper end of the lower positioning plate 3. The first earthquake-proof component 6 includes an upper fixed plate 10, a lower fixed plate 11, a two-way shock-absorbing member 61, a reset spring 62, a connecting plate 63, a force transmission push rod 64, a positioning block 65, a hinge block 66, a sliding rod 67, a first spring 68 and a connecting seat 69. The lower fixed plate 11 is fixedly arranged at the upper end of the lower positioning plate 3, the two-way shock-absorbing member 61 is symmetrically arranged at the upper end of the lower fixed plate 11, the positioning block 65 is fixedly arranged at the middle position of the upper end of the lower fixed plate 11, and the connecting seat 69 is symmetrically arranged on both sides of the positioning block 65 , one end of the sliding rod 67 is connected to the positioning block 65 and the other end is connected to the connecting seat 69, the hinge block 66 is slidably connected to the sliding rod 67, the first spring 68 is arranged on the surface of the sliding rod 67, the upper fixed plate 10 is fixedly arranged at the lower end of the upper positioning plate 2, the connecting plate 63 is fixedly arranged at the middle position of the lower end of the upper fixed plate 10, the return spring 62 is symmetrically arranged on both sides of the connecting plate 63, the force transmission push rod 64 is hinged to the surface of the connecting plate 63, and the other end of the force transmission push rod 64 is hinged to the hinge block 66. When vibration occurs, the steel structure building 5 moves, and the force is transmitted to the upper fixed plate 10 through the upper positioning plate 2. The upper fixed plate 10 moves up and down. When the upper fixed plate 10 moves downward, a downward force is applied to the return spring 62 and the connecting plate 63. The return spring 62 undergoes elastic deformation and squeezes downward, and the connecting plate 63 drives the force transmission push rod 64 to disperse the force, thereby reducing the damage to the lower concrete pouring layer 4, thereby reducing shock and buffering.

The bidirectional shock absorber 61 includes a buffer column 611, a support plate 612, a high-pressure spring 613, a piston 614, a hydraulic cylinder 615 and a piston rod 616. The hydraulic cylinder 615 is connected to the upper positioning plate 2 and the lower fixing plate 11 through the buffer column 611. The support plate 612 is fixedly arranged in the middle of the inner cavity of the hydraulic cylinder 615. The high-pressure spring 613 is symmetrically connected to both ends of the support plate 612. The piston 614 is movably connected to the telescopic end of the high-pressure spring 613. The piston rod 616 is fixedly connected to the piston 614. When in use, the stiffness and damping of the bidirectional shock absorber 61 can be adjusted by the tightness and position of the bolts. The bidirectional shock absorber 61 can be optimized and adjusted according to the height, material and local geographical location of the steel structure building to obtain the best shockproof effect.

The second shockproof component 7 includes a memory metal 701, a rubber layer 702 and a steel plate layer 703. The rubber layer 702 and the steel plate layer 703 are equidistantly installed between the upper positioning plate 2 and the lower positioning plate 3. The memory metal 701 is fixed in the middle position between the rubber layer 702 and the steel plate layer 703. The interactive superposition design of the rubber layer 702 and the steel plate layer 703 significantly improves the shockproof effect, energy consumption and dispersion, adjusts the stiffness and damping characteristics, and improves the durability and reliability, thereby improving the shock resistance of the steel structure and the safety of the overall structure.

The elastic connecting member 9 includes a sleeve 901, a second spring 902, a telescopic rod 903 and a stop plate 904. The sleeve 901 is fixedly connected to the first shockproof component 6. The telescopic rod 903 is sleeved in the sleeve 901, and the inner wall of the telescopic rod 903 is connected to the inner wall of the bottom of the sleeve 901 through the second spring 902. The stop plate 904 is movably connected to the telescopic end of the telescopic rod 903, and its outer wall is in contact with the outer wall of the second shockproof component 7. When vibrating, the telescopic rod 903 will move in the sleeve 901 and compress the second spring 902, thereby reducing the internal friction and collision between the two shockproof components and achieving a certain shock-absorbing effect.

The outermost layer of the anti-vibration support 1 is provided with a protective layer 8, and the protective layer 8 has the functions of flame retardancy, heat insulation, corrosion resistance and aging resistance.

When in use, the upper positioning plate 2 is connected to the steel structure building 5 by bolts, and the lower positioning plate 3 is connected to the concrete pouring layer 4 by bolts. When vibration occurs, the bearing capacity of a certain part of the steel structure building 5 suddenly increases. At this time, the first shockproof component 6, the second shockproof component 7 and the elastic connector 9 start to move. The first shockproof component 6 receives the vibration transmitted by the steel structure building 5 through the upper fixed plate 10. At this time, the upper fixed plate 10 drives the fixedly connected connecting plate 63 to move downward, and the connecting plate 63 drives the hinged force transmission push rod 64 to push the hinge block 66 on the slide rod 67 to the left and right. The hinge block 66 drives the first spring 68 to deform in the same direction, and the reset spring 62 is elastically deformed downward due to the force of the vibration. The piston rod 616 in the two-way shock absorbing member 61 moves downward, and the vibration is initially suppressed by the buffer column 611. The piston rod 616 pushes the piston 614 to slide downward, and the piston 614 squeezes the high-pressure spring 613 to achieve longitudinal shock absorption. When the second shockproof component 7 is subjected to the downward pressure generated by the vibration, the rubber layer 702 plays a preliminary buffering role on the vibration, and the steel plate layer 703 prevents the rubber layer 702 from being dented due to the deformation caused by the extrusion. The interactive superposition of the rubber layer 702 and the steel plate layer can realize the consumption of energy and the dispersion of pressure. The deformation of the rubber layer 702 and the elastic recovery of the steel plate layer 703 work together to absorb the vibration energy and convert it into elastic potential energy. The telescopic rod 903 in the elastic connector 9 moves in the sleeve 901, and the second spring 902 undergoes elastic deformation to disperse the pressure generated by the vibration again, thereby effectively preventing shock and protecting the steel structure building 5 from damage.

In this process, the first shockproof component 6 realizes a longitudinal shockproof effect, the second shockproof component 7 realizes a lateral shockproof effect, and the elastic connecting member 9 reduces the friction force generated when the two shockproof components vibrate.

The above description is only a preferred embodiment of the present utility model patent and is not intended to limit the present utility model patent. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model patent shall be included in the protection scope of the present utility model patent.
