[0001] The present invention relates to the technical field of steel structure frames, and more particularly to an earthquake-resistant thin and flexible steel structure frame. Background Art

[0002] There are various types of housing construction, which can be classified according to their uses and forms. According to their uses, housing construction can include residential buildings, commercial buildings, office buildings, industrial buildings, public buildings, etc. Residential buildings are where people live, which can be independent houses, apartment buildings or centralized residential areas. With the improvement of people's living standards, housing construction has gradually developed universally. Steel structure frames will be used in the process of housing construction, and earthquake-resistant thin and flexible steel structure frames are a structural form used in modern architectural design to improve the earthquake resistance of buildings. It combines the advantages of thin-walled steel materials with the form of structural frames to achieve stability and safety under external forces such as earthquakes.

[0003] Among them, the patent with announcement number CN216664474U discloses a steel structure earthquake-resistant frame structure, which relates to the technical field of steel structure, including a first U-shaped frame and a second U-shaped frame, the tops of the first U-shaped frame and the second U-shaped frame are fixedly connected to two fixing rods, the tops of the fixing rods are provided with mounting grooves, the inner walls of the mounting grooves of the fixing rods are fixedly connected to telescopic rods, the outer side of the telescopic rods is sleeved with a first spring, the tops of the telescopic rods are fixedly connected to movable rods, and the tops of the movable rods are fixedly connected to crossbeams; When the structure is in use, when the crossbeam is supported and subjected to a large impact, the crossbeam moves downward, driving the movable rod to move in the installation groove, and squeezing the telescopic rod and the first spring downward, the first spring cushions the crossbeam, and improves the overall stability of the device. At the same time, the crossbeam moves downward, pressing the rotating rod to squeeze the movable ring to move to both sides, the movable ring squeezes the second spring, the second spring cushions the rotating rod, and further improves the seismic buffering capacity. However, when the structure is in use, the device itself is used as the supporting point for seismic protection, and it cannot play the role of wrapping the columns required for the building for seismic protection. At the same time, the elasticity of the spring itself will also generate amplitude when the force is released, resulting in poor seismic effect. Summary of the invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a seismic-resistant thin and flexible steel structure frame, aiming to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solutions: an earthquake-resistant thin and flexible steel structure frame, comprising a column, and a protective support assembly is arranged on the outer side of the column; The protective support assembly includes a limiting sleeve arranged on the outside of the column, a plurality of first pull plates are distributed on the outside of the limiting sleeve, and a second pull plate is arranged between each two adjacent first pull plates; The first pull plate is provided with a first hook at the top and bottom, the second pull plate is provided with a second hook at the top and bottom, and each of the first hook and the second hook is provided with an elastic tension relief rib; A limiting ring is arranged between the second pull plate and the first pull plate, the second pull plate is located on the outside of the limiting ring, a plurality of first clamping plates are distributed on the limiting ring, and a plurality of limiting screws are arranged on each of the first clamping plates, a plurality of second clamping plates are distributed on the outside of the limiting ring, a plurality of the second clamping plates are respectively located on one side of the corresponding first clamping plates, and one end of the limiting screw is mounted on the second clamping plate through a nut, and the second clamping plate is located on one side of the second pull plate and is fixedly connected to the second pull plate.

[0006] It can be seen that in the above technical solution, the limit sleeve is arranged on the outside of the column, and the limit sleeve is used as a support point to prevent foreign objects from causing damage to the column. When the steel structure is being built, the limit ring is used as a support point. The force generated when the amplitude is transmitted to the limit ring through the first clamping plate and the second clamping plate for dispersion. At the same time, the second pull plate can absorb the amplitude generated by the limit ring and transmit it to the elastic stress relief rib. The elastic stress relief rib produces shaking to weaken the amplitude of the steel structure, which can effectively improve the seismic performance of the device when in use. Optionally, in a possible implementation manner, a plurality of limiting shaft sleeves are fixedly provided on both sides of the surface of the limiting sleeve, a plurality of the limiting shaft sleeves are rotatably connected with rotating rods, and an inclined rod is fixedly provided at one end of each of the two adjacent rotating rods, and a sliding sleeve is slidably connected to the two adjacent inclined rods, the inclined rod cover is arranged on the outer side of the limiting ring, a positioning cavity is formed between the limiting sleeve and the column, an inner liner is arranged in the positioning cavity, the inner liner sleeve is arranged on the outer side of the column and is detachably connected to the column by bolts, a sliding groove is provided on the outer side of the limiting ring, a sliding block is fixedly provided on one side of the second splint, and the sliding block extends to the sliding The first pull plate includes a first extension piece and a second extension piece, the first extension piece and the second extension piece are stacked, and a center piece is arranged between the first extension piece and the second extension piece, a knob is rotatably connected to the middle of the center piece, a bidirectional screw is fixedly arranged in the middle of the knob, and the second extension piece and the first extension piece are both provided with screw holes threadedly connected to the bidirectional screw, and the thread guides at both ends of the bidirectional screw are arranged oppositely, and guide rods fixed on the center piece are arranged on both sides of the knob, and the two ends of the guide rods are respectively threadedly connected to the second extension piece and the first extension piece; It can be seen that in the above technical solution, the two-way screw rod is driven to rotate by rotating the knob. When the two-way screw rod rotates, the second extension member and the first extension member are displaced by the traction force when the two-way screw rod rotates, thereby expanding the support range of the first pull plate for the elastic stress relief rib strip, so that the first hook can be tightly hooked with the elastic stress relief rib strip, and the first hook is driven to move by the displacement of the first extension member and the second extension member. When the device is in use, the nut on the second clamping plate is loosened, and then the first clamping plate, the limit screw and the second clamping plate can pass through the corresponding matching of the slider and the liner. The cam is used to slide on the limit ring to adjust the position, thereby realizing the function of adjusting the position of the second pull plate, and then realizing the function of stretching the elastic stress relief ribs, so as to adjust the tightness of the elastic stress relief ribs, and easily transmit the amplitude to the elastic stress relief ribs, so that the elastic stress relief ribs produce shaking and weaken it. When the inclined rod is subjected to force, it will pass through the rotating rod and deflect along the axial point of the connection between the rotating rod and the limiting shaft sleeve, and the impact force received will be weakened. At the same time, when the inclined rod is deflected, it will rub against the inclined rod, which is used to ensure the stability of the inclined rod when it is deflected, and also facilitates the subsequent resetting of the inclined rod, so that the two adjacent inclined rods can be staggered together.

[0007] Technical effects and advantages of the present invention: 1. The present invention uses the limit sleeve as a support point to prevent foreign objects from damaging the column. When the steel structure is built, the limit ring is used as a support point. The force generated by the amplitude is transmitted to the limit ring and dispersed through the first clamping plate and the second clamping plate. At the same time, the second pull plate can absorb the amplitude generated by the limit ring and transmit it to the elastic stress relief rib. The elastic stress relief rib shakes to weaken the amplitude of the steel structure, which can effectively improve the seismic performance of the device when in use; 2. The present invention displaces the second extension piece and the first extension piece through the traction force when the bidirectional screw is rotated, thereby expanding the support range of the first pull plate for the elastic stress relief rib, so that the first hook can be tightly hooked with the elastic stress relief rib, and by loosening the nut on the second clamping plate, the first clamping plate, the limiting screw and the second clamping plate can slide on the limiting ring through the corresponding cooperation of the slider and the liner to adjust the position, thereby realizing the function of adjusting the position of the second pull plate, and then realizing the function of stretching the elastic stress relief rib, realizing the adjustment of the tightness of the elastic stress relief rib, facilitating the amplitude transmission to the elastic stress relief rib, and weakening the shaking of the elastic stress relief rib; 3. The present invention unscrews the nut on the second clamping plate, and then enables the first clamping plate, the limiting screw and the second clamping plate to slide on the limiting ring through the corresponding cooperation of the slider and the liner to adjust the position, thereby realizing the function of adjusting the position of the second pull plate, and then realizing the function of stretching the elastic stress relief ribs, thereby adjusting the tightness of the elastic stress relief ribs, facilitating the amplitude transmission to the elastic stress relief ribs, causing the elastic stress relief ribs to shake, thereby weakening the amplitude; To sum up, the overall design is simple and the structure is reasonable. Through the corresponding coordination of various structures, the limit sleeve is used as the support point to prevent foreign objects from causing damage to the column. The force generated when subjected to the amplitude is transmitted to the limit ring and dispersed through the first clamp and the second clamp. At the same time, the second pull plate can absorb the amplitude generated by the limit ring and transmit it to the elastic stress relief ribs. The elastic stress relief ribs produce shaking to weaken the amplitude of the steel structure, which can effectively improve the seismic performance of the device when in use, and extend the support range of the first pull plate for the elastic stress relief ribs so that the first hook can be tightly hooked with the elastic stress relief ribs. The first hook is driven to move by the displacement of the first extension member and the second extension member, and the position of the first clamp, the limit screw and the second clamp on the limit ring is adjusted to realize the function of adjusting the position of the second pull plate, and then the function of stretching the elastic stress relief ribs is realized, which makes it easy to transmit the amplitude to the elastic stress relief ribs to quickly reduce the amplitude, thereby improving the seismic performance of the device.

It is convenient for the first hook 4 to be tightly hooked with the elastic stress relief rib 5, and the first hook 4 is driven to move by the displacement of the first extension member 19 and the second extension member 20, and the position of the first clamping plate 7, the limiting screw 8 and the second clamping plate 9 on the limiting ring 6 is adjusted to achieve the function of adjusting the position of the second pull plate 10, and then the function of stretching the elastic stress relief rib 5 is achieved, and the tightness of the elastic stress relief rib 5 is adjusted, and the amplitude is easily transmitted to the elastic stress relief rib 5, and the elastic stress relief rib 5 produces shaking to weaken it, which is convenient to quickly reduce the amplitude and improve the seismic performance of the device. The specific structural arrangement of the component is as follows; The protective support assembly includes a limiting sleeve 2 arranged on the outside of the column 1, and a plurality of first pull plates 3 are distributed on the outside of the limiting sleeve 2, and a second pull plate 10 is arranged between each two adjacent first pull plates 3; The first pull plate 3 is provided with a first hook 4 at the top and bottom, the second pull plate 10 is provided with a second hook 11 at the top and bottom, and each of the first hook 4 and the second hook 11 is provided with an elastic tension relief rib 5; A limiting ring 6 is arranged between the second pull plate 10 and the first pull plate 3, the second pull plate 10 is located on the outside of the limiting ring 6, a plurality of first clamping plates 7 are distributed on the limiting ring 6, and a plurality of limiting screws 8 are arranged on each first clamping plate 7, a plurality of second clamping plates 9 are distributed on the outside of the limiting ring 6, the plurality of second clamping plates 9 are respectively located on one side of the corresponding first clamping plates 7, and one end of the limiting screw 8 is installed on the second clamping plate 9 through a nut, and the second clamping plate 9 is located on one side of the second pull plate 10 and is fixedly connected to the second pull plate 10.

[0020] A plurality of limiting sleeves 12 are fixedly provided on both sides of the surface of the limiting sleeve 2, and a plurality of limiting sleeves 12 are rotatably connected with a rotating rod 15, and an inclined rod 14 is fixedly provided at one end of each of the two adjacent rotating rods 15, and a sliding sleeve 13 is slidably connected to each of the two adjacent inclined rods 14, and the inclined rod 14 is covered on the outside of the limiting ring 6, and a positioning cavity 17 is formed between the limiting sleeve 2 and the column 1, and a lining 16 is provided in the positioning cavity 17, and the lining 16 is sleeved on the outside of the column 1 and is detachably connected to the column 1 by bolts, and a sliding groove 18 is provided on the outside of the limiting ring 6, and a slider is fixedly provided on one side of the second clamping plate 9, and the slider extends into the sliding groove 18 and is slidably connected to the sliding groove 18. The first pull plate 3 includes a first extension piece 19 and a second extension piece 20, which are stacked and a center piece 21 is arranged between the first extension piece 19 and the second extension piece 20, a knob 22 is rotatably connected to the middle of the center piece 21, a bidirectional screw rod 24 is fixedly arranged in the middle of the knob 22, and a thread hole 23 threadedly connected to the bidirectional screw rod 24 is opened on the second extension piece 20 and the first extension piece 19, and the thread guides at both ends of the bidirectional screw rod 24 are arranged in opposite directions, and guide rods 25 fixed on the center piece 21 are arranged on both sides of the knob 22, and the two ends of the guide rod 25 are respectively threadedly connected to the second extension piece 20 and the first extension piece 19.

[0021] According to the above structure, when the staff is providing earthquake-resistant protection support for steel structure equipment such as column 1, the limit sleeve 2 is installed on the outside of the column 1, and the limit sleeve 2 is used as the support point to prevent foreign objects from causing damage to the column 1. When the steel structure is being erected, the limit ring 6 is used as the support point. The force generated by the amplitude is transmitted to the limit ring 6 and dispersed through the first clamping plate 7 and the second clamping plate 9. At the same time, the second pull plate 10 can absorb the amplitude generated by the limit ring 6 and transmit it to the elastic strain relief rib 5. The elastic strain relief rib 5 produces shaking to weaken the amplitude of the steel structure, which can effectively improve the earthquake resistance of the device when in use.

[0022] When the device is in use, the two-way screw rod 24 is driven to rotate by rotating the knob 22. When the two-way screw rod 24 rotates, the second extension piece 20 and the first extension piece 19 are displaced due to the traction force when the two-way screw rod 24 rotates, thereby expanding the support range of the first pull plate 3 for the elastic stress relief rib 5, so that the first hook 4 can be tightly hooked with the elastic stress relief rib 5, and the first hook 4 is driven to move by the displacement of the first extension piece 19 and the second extension piece 20.

[0023] At the same time, through the arrangement of the inclined rod 14, when the inclined rod 14 is subjected to force, it will pass through the rotating rod 15 and deflect along the axial point of the connection between the rotating rod 15 and the limiting shaft sleeve 12, so that the impact force received is weakened. At the same time, when the inclined rod 14 is deflected, it will rub against the inclined rod 14, which is used to ensure the stability of the inclined rod 14 when it is deflected, and it is also convenient for the subsequent resetting of the inclined rod 14, so that two adjacent inclined rods 14 can be staggered together.

[0024] Different from the prior art, the present application discloses an earthquake-resistant thin and flexible steel structure frame. Through the corresponding coordinated use of various structures, the limit sleeve 2 is used as the support point to avoid damage to the column 1 caused by impact. The force generated when subjected to amplitude is transmitted to the limit ring 6 and dispersed through the first clamping plate 7 and the second clamping plate 9. At the same time, the second pull plate 10 can absorb the amplitude generated by the limit ring 6 and transmit it to the elastic stress relief rib 5. The elastic stress relief rib 5 produces shaking to weaken the amplitude of the steel structure, which can effectively improve the earthquake resistance of the device when in use, and prolong the first pull plate 3 on the elastic stress relief rib 5.
