Description

Technical Field

[0001] The present invention relates to the technical field of building steel structures, in particular to a multi-angle earthquake-resistant building steel structure. Background Art

[0002] Building steel structure is a widely used form of building structure with many subcategories, including light steel structure, high-rise steel structure, residential steel structure, space steel structure and bridge steel structure. This structure is widely used in various engineering constructions, such as steel bridges, steel workshops, steel gates, large pipeline containers, high-rise buildings and tower rail mechanisms. As a structure in a building, it needs to have a certain degree of protection against some disasters, such as earthquakes. Earthquakes can affect rigid structures. The impact of earthquakes on buildings is mainly reflected in two aspects: structural damage and loss of function. First, earthquake vibrations can cause the structure of the building to be subjected to forces exceeding its bearing capacity, thereby causing structural damage. The propagation mode of seismic waves determines the main way in which buildings are damaged by earthquakes. Simply put, there are three ways for buildings to be damaged: up and down bumps, horizontal swaying, and left and right torsion. Therefore, it is best to provide a building steel structure that can provide a certain buffer against all three ways.

[0003] Chinese patent authorization announcement number CN113914495B discloses an earthquake-resistant steel building structure, which belongs to the field of construction. A blocking plate is provided in conjunction with a mounting plate and roller on the lower surface of a linkage rod to indirectly suppress the up and down vibration of a connecting column. When the connecting column vibrates up and down, the mounting plate collides back and forth with the blocking plate, accelerating the conversion of the connecting column's kinetic energy, causing the connecting column to stop more quickly and improving the earthquake resistance. The friction between a first deceleration member and a second deceleration member allows the connecting column and the buffer plate to decelerate more quickly, allowing the buffer plate and the connecting column to stop more quickly. The combination of the mounting plate and the blocking plate improves the earthquake resistance of the device.

[0004] The Chinese patent authorization announcement number CN110344635B is an earthquake-resistant building steel structure, which includes a horizontal steel bar, a lower inclined surface, a spring sleeve column I, a spring I vertical rail rod, a hollow rod, a circular ring, an insert rod, a spring II, an upper and lower movable plate, and an inclined plate I. The present invention can provide multi-level earthquake resistance and effectively resist the vibrations suffered by the steel structure. The lower side of the horizontal steel bar is provided with a lower inclined surface, and the left and right ends of the lower inclined surface are fixedly connected to the spring sleeve column I, and the two spring sleeve columns I are sleeved with springs I, and the left and right ends of the inclined plate I are respectively slidably connected to the two spring sleeve columns I, and the two springs I are both located between the horizontal steel bar and the inclined plate I, and the left and right ends of the upper side of the horizontal steel bar are fixedly connected to the vertical rail rod, and the left and right ends of the upper and lower movable plates are respectively slidably connected to the two vertical rail rods, and two hollow rods are symmetrically provided on the left and right sides, and the upper ends of the two hollow rods are hingedly connected to the middle of the upper and lower movable plates, and the lower ends of the two hollow rods are fixedly connected to circular rings;

[0005] The Chinese patent authorization announcement number CN113314052B is an earthquake-resistant building steel structure, comprising a base, a cushioning airbag sleeved on the base, two first hollow support rods fixedly connected to the base, and a T-shaped rod slidably connected to the first hollow support rod. The present invention can convert harmful vibration force into beneficial energy through the cooperation of the vibration plate and the piezoelectric ceramic plate, so that the device can automatically lower its height in the event of an earthquake, improve its own stability and earthquake resistance, and avoid greater damage and loss when it may fall, while reducing the cost of using the device. In addition, the device can provide all-round cushioning protection for the device with the cooperation of various buffer mechanisms and cushioning airbags, further improving the earthquake resistance of the device, and the device can give people a dual visual and auditory warning when vibration occurs;

[0006] The above-mentioned existing technical solutions have the following defects: they can only buffer longitudinal earthquake waves, or buffer transverse waves after changing the direction, and are difficult to adapt to buffering other possible waveforms. Most of them use springs for earthquake resistance, which affects their service life and is difficult to replace. Therefore, the present invention provides a multi-angle earthquake-resistant building steel structure to solve the above-mentioned problems. Summary of the Invention

[0025] Compared with the prior art, the present invention has the following advantages: the multi-angle seismic-resistant building steel structure can adapt to multiple waveforms for buffering, can achieve multi-angle seismic resistance, has a long service life, and is also convenient for continued use after the damping oil is replaced in the later stage;

[0026] 1. A through-hole structure is provided at the inner end of the connecting shaft, a protrusion structure is provided on the outer side of the connecting shaft, a hole structure is provided on the inner side of the protrusion structure, and the protrusion structure is symmetrically arranged about the center of the connecting shaft, and the protrusion structure and the through-hole structure of the connecting shaft are staggered at equal angles. When the support rod is affected by different seismic waves, it can rotate and move left and right to adapt to seismic waves of different waveforms;

[0027] Furthermore, the shock-absorbing ring group is composed of multiple groups of concentric rings, and the ring units are elastically connected by springs, and the inner ring of the ring is connected to the outer side of the support rod in a snap-fit ​​rotational connection, and the outer ring of the ring is connected to the inner side of the support frame in a snap-fit ​​rotational connection, which can further buffer and reduce earthquake shear waves.

[0028] Furthermore, the first mounting plate and the second mounting plate are both slidably connected to the limit rod, the first mounting plate is slidably connected to the raised annular structure on the inner side of the support frame, the second mounting plate is slidably connected to the limit plate, and through-hole structures are formed at equal angles on the upper and lower sides of the second mounting plate, and a hole structure is formed at equal angles on the upper side of the first mounting plate, so that damping oil can flow in the hole structure, thereby limiting the movement speed and buffering the seismic shear wave.

[0029] Furthermore, the limit blocks are arranged at equal angles on the upper side of the support frame, and the longitudinal section of the limit blocks is trapezoidal. The limit blocks are arranged in a one-to-one correspondence with the hole-shaped structure opened on the lower side of the support beam body, and the diameter of the hole-shaped structure opened on the lower side of the support beam body is larger than the diameter of the buffer sleeve. The support beam body can be limited within a certain range and avoid a completely rigid connection. It can also be limited by the support frame to avoid separation, thereby performing all-round buffering and reduction.

[0030] The above structures cooperate to form a multi-angle reduction and earthquake resistance for various seismic waves;

[0031] 2.

This can limit the rotation of the steel structure installed on the mounting cylinder, thereby increasing the seismic buffering effect on other structures.

[0032] Furthermore, the sliding fit between the connecting rod and the mounting tube can restrict the movement of the connecting rod to a certain extent. After the connecting rod moves, the air inside the mounting tube is compressed, thereby providing a buffer, so that the spacing between the individual units of the multi-angle anti-seismic base can be adjusted to a certain extent.

[0033] 3. A sealing ring structure is provided on the inner side of the first mounting plate and the second mounting plate to increase the sealing performance, and the upper cavity of the support frame is filled with damping oil, so that the shock-absorbing structure inside the support frame can continue to be filled with damping oil for maintenance in the later stage, without the need to disassemble and replace the spring for maintenance. At the same time, if the damping oil inevitably leaks, it can leak into the mounting base for collection and lubrication of the spring. BRIEF DESCRIPTION OF THE DRAWINGS
