As shown in fig. 1 to 7, an earthquake-resistant steel structure provided by an embodiment of the invention includes a first earthquake-resistant member and a second earthquake-resistant member.
The first shock-resistant member can vertically connect the vertical bar 130 and the horizontal bar 140 by means of screws. In this embodiment, the first anti-seismic member is a supporting plate 110, the supporting plate 110 is slightly rectangular, one right-angle side of the supporting plate 110 is connected to the vertical rod 130, and the other right-angle side of the supporting plate 110 is connected to the cross rod 140, wherein the screw used for connecting the supporting plate 110 and the vertical rod 130 is a high-strength screw, and the screw used for connecting the supporting plate 110 and the cross rod 140 is a low-strength screw. During an earthquake, the earthquake resistance of the low-strength screws is lower than that of the high-strength screws, and the earthquake can break the low-strength screws, so that the cross bar 140 is disconnected from the support plate 110.
The second anti-seismic member includes an energy dissipation member and two connecting members, wherein one connecting member is fixedly connected to the vertical rod 130, the other connecting member is fixedly connected to the cross rod 140, in this embodiment, the connecting members can be connecting plates 120, wherein one connecting plate 120 is fixedly connected to the vertical rod 130 through screws, the other connecting plate 120 is fixedly connected to the cross rod 140 through screws, and screws used for connecting the connecting plate 120 to the cross rod 140 or the vertical rod 130 are high-strength screws.
The energy dissipation member is disposed between the two connection members, and the energy dissipation member can adjust the amplitude of the cross bar 140, and in the event of an earthquake, the transverse wave of the earthquake causes the cross bar 140 to reciprocally fluctuate in the horizontal direction. The energy dissipation member is disposed between the two connecting members, the energy dissipation member is located below the cross bar 140, and the energy dissipation member is located at an angle of forty-five degrees with respect to the horizontal plane in the initial state, so that the orthographic projection of the energy dissipation member, the cross bar 140 and the vertical bar 130 forms an isosceles right triangle. The energy dissipation member initially has standard power consumption, and reduces the standard power consumption to consume energy when the amplitude of the cross bar 140 is smaller than the minimum value of the first preset interval, and consumes energy with the standard power consumption when the amplitude of the cross bar 140 is in the first preset interval, and increases the standard power consumption to consume energy when the amplitude of the cross bar 140 is larger than the maximum value of the first preset interval.

The piston rod 240 coaxially penetrates through the piston cylinder 210, the piston rod 240 is in sealing connection with the piston cylinder 210, one end of the piston rod 240, which is positioned in the piston cavity 211, is connected with the piston disc 230, and one end of the piston rod 240, which is positioned outside the piston cavity 211, is in rotational connection with a connecting piece on the cross rod 140; the end of the piston cylinder 210 far away from the piston rod 240 is rotationally connected with the connecting piece on the vertical rod 130, and when the horizontal rod 140 fluctuates on the horizontal plane, the end of the piston rod 240 in the piston cavity 211 drives the piston disc 230 to move in the piston cavity 211, so that energy is consumed when the horizontal rod 140 fluctuates due to an earthquake.
In one embodiment, the energy consuming member further comprises an adjustment unit for adjusting the size of the piston bore 231 in the piston disc 230. Specifically, the adjusting unit includes an adjusting disk 260, a sensing block, an adjusting piece, and an adjusting cylinder 250.

In combination with the above embodiments, the working process of the anti-seismic steel structure provided by the embodiment of the invention is as follows:
in operation, the adjusting plate 260 is set to block the piston holes 231 on one half of the piston plates 230, and the first elastic member and the second elastic member 450 are set to be in the original length state. During an earthquake, transverse waves of the earthquake are transmitted to the transverse rods 140 through the vertical rods 130, and the vibration amplitude of the transverse rods 140 on the horizontal plane causes the low-strength screws to break.
The transverse wave of the earthquake causes the transverse rod 140 to wave on the horizontal plane, the wave of the transverse rod 140 drives the piston disc 230 to slide in the piston cavity 211 through the piston rod 240, the piston disc 230 has resistance in the process of sliding in the piston cavity 211, and certain energy can be consumed in the process of sliding in the piston cavity 211 by the piston disc 230, so that the energy brought by the transverse wave of the earthquake is consumed.
In the initial state, the collar is positioned in the positioning groove 434, and the first ring 311 of the collar abuts against the inner side wall of the adjusting cylinder 250. When the fluctuation amplitude of the cross rod 140 is smaller than the minimum value of the first preset interval, the fluctuation of the cross rod 140 drives the piston rod 240 to angularly deflect, the first section 241 of the piston rod 240 slides in the piston cavity 211 to a small extent, the first section 241 of the piston rod 240 can drive the lantern ring 310 to synchronously move in the sliding process of the piston cavity 211, the peripheral wall of the lantern ring breaks through the positioning groove 434 and then slides along the first stage 431 of the push rod 430, the push rod 430 is pushed by the lantern ring in the sliding process of the first stage 431, the push rod 430 drives the adjusting toothed rod 420 to synchronously slide along the radial direction of the adjusting cylinder 250, the adjusting toothed rod 420 drives the adjusting gear 410 to start rotating, and the rotation of the adjusting gear 410 drives the first section 241 to rotate due to the coaxial sliding connection of the adjusting gear 410 and the rotation of the first section 241 drives the adjusting disc 260 to synchronously rotate. Since the adjusting disc 260 seals half of the piston holes 231 in the initial state, at this time, the rotation of the adjusting disc 260 gradually opens half of the sealed piston holes 231, and the resistance force applied to the sliding of the piston disc 230 in the piston cavity 211 gradually decreases, so as to avoid local excessive torsion to the vertical rod 130 during small-amplitude fluctuation, thereby ensuring the stability of the vertical rod 130.
When the fluctuation amplitude of the cross rod 140 is in a first preset interval, the fluctuation of the cross rod 140 drives the piston rod 240 to angularly deflect, the first section 241 of the piston rod 240 can drive the lantern ring 310 to synchronously move in the sliding process of the piston cavity 211, the peripheral wall of the lantern ring breaks through the positioning groove 434 and then slides along the first stage 431 of the pushing rod 430, then the peripheral wall of the lantern ring enters the second stage 432, the pushing rod 430 cannot be pushed by the lantern ring because the second stage 432 is arranged in parallel with the first section 241, at this time, the adjusting toothed bar 420 and the adjusting gear 410 are kept in a relatively static state, the adjusting disc 260 is in a state of not blocking the piston hole 231, namely, the piston hole 231 is in a completely opened state, and at this time, the fluctuation of the cross rod 140 is in an interval which the cross rod 140 can bear.
When the fluctuation amplitude of the cross rod 140 is larger than the maximum value of the first preset interval, the fluctuation of the cross rod 140 drives the piston rod 240 to angularly deflect, the first section 241 of the piston rod 240 slides in the piston cavity 211 to a large extent, the first section 241 of the piston rod 240 can drive the lantern ring 310 to synchronously move in the sliding process of the first section 241 of the piston rod 240, the outer peripheral wall of the lantern ring breaks through the positioning groove 434 and then slides along the first section 431 of the push rod 430, then enters the third section 433 through the second section 432, the lantern ring slides in the third section 433, the push rod 430 is pushed by the lantern ring to be further away from the axis of the adjusting cylinder 250, the push rod 430 drives the adjusting toothed rod 420 to synchronously slide along the radial direction of the adjusting cylinder 250, the adjusting toothed rod 420 drives the adjusting gear 410 to rotate at an increased angle, and as the adjusting gear 410 and the first section 241 are coaxially and slidably connected, the rotation of the adjusting gear 410 drives the first section 241 to synchronously rotate, and the rotation of the first section 241 drives the adjusting disc 260 to synchronously rotate. Since the piston hole 231 on the piston plate 230 is in a fully opened state when the collar slides in the second stage 432, the piston hole 231 is gradually blocked by the rotation of the adjusting plate 260 when the collar slides along the third stage 433, the resistance to sliding of the piston plate 230 in the piston cavity 211 is gradually increased, the resistance to sliding of the piston plate 230 in the piston cavity 211 is increased, the energy absorbed by the sliding of the piston plate 230 in the piston cavity 211 is increased, the fluctuation of the cross bar 140 on the horizontal plane is reduced, the fluctuation of the cross bar 140 on the horizontal plane is ensured to be in a stable section, and the stability of the connection between the vertical bar 130 and the cross bar 140 is increased.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
