[0001] The invention relates to the technical field of steel structure load-bearing components, and in particular to an earthquake-resistant steel structure load-bearing component. Background Art

[0002] In the process of modern engineering construction, steel structure is one of the common main construction bodies, especially for some larger projects, steel structure is needed to maintain the stability and strength of the main structure. In the actual construction and application process, steel structure requires the use of a variety of accessories, and steel structure load-bearing components are one of them. During the construction process, multiple sets of steel structure load-bearing components are generally installed at the bottom of the steel structure body, so as to achieve stable support assembly of the steel structure; When existing steel structure load-bearing components are in use, in order to ensure the stability of the steel structure load-bearing components themselves, the ground is generally hardened and the steel structure load-bearing components are pre-buried below the ground. However, in actual use, due to the complexity and diversity of the environment, ground subsidence may still occur during subsequent use, especially when the ground sinks locally. Since steel structure load-bearing components are generally used in groups, once the above-mentioned ground sinks locally, some steel structure load-bearing components will sink with the ground, thereby making their supporting effect on the steel structure ineffective, causing the remaining steel structure load-bearing components to be under excessive pressure, which may even cause the steel structure to break and collapse in severe cases, thereby greatly affecting its safety.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Embodiment 1:

[0020] See also Figure 1-Figure 8 as well as Fig.11 As shown, an earthquake-resistant steel structure load-bearing member includes an embedded box 1, a movable bin 4 is penetrated through the top of the embedded box 1, a rubber block 5 is installed on the top of the movable bin 4, and a connector 6 is installed on the top of the rubber block 5, and a supporting threaded column 7 is arranged at the bottom of the embedded box 1, and the supporting threaded column 7 penetrates the bottom end of the movable bin 4; The connecting piece 6 can be in the form of a flange or the like, and the outer wall of the embedded box 1 can be coated with a corrosion-resistant layer, so that when in use, it can be installed at the bottom of the steel structure body 29 through the cooperation of the connecting piece 6 and accessories such as screws, and support the steel structure body 29. At the same time, the embedded box 1 is embedded below the ground, and the corrosion-resistant layer coated on the outside of the embedded box 1 can effectively resist possible corrosion below the ground; The outer wall of the embedded box 1 is evenly installed with threaded steel bars 2, and the side wall of the embedded box 1 is installed with a blocking plate 3; The above-mentioned threaded steel bar 2 can be installed on the embedded box body 1 by welding, and the blocking plate 3 can be made as an integrated unit with the embedded box body 1. The threaded steel bar 2 can be provided in multiple groups according to actual needs, and the outer wall of the threaded steel bar 2 can also be coated with a corrosion-resistant coating. During the application process, the threaded steel bar 2 can be embedded below the ground along with the embedded box body 1, effectively increasing the adhesion to the ground and the sinking resistance. The blocking plate 3 is located above the ground, and the bottom of the blocking plate 3 is fully in contact with the ground, thereby further increasing the sinking resistance. The support threaded column 7 is rotatably connected to the embedded box 1, and the support threaded column 7 is threadably connected to the movable bin 4; The support threaded column 7 and the embedded box 1 can be connected by a giant thrust bearing to ensure the support force of the support threaded column 7 itself. During the application process, the support threaded column 7 and the movable bin 4 are threadedly connected, so that the support threaded column 7 and the movable bin 4 can effectively provide an upward support force. At the same time, the embedded box 1 provides an upward support force for the support threaded column 7, so that the component can effectively support the steel structure main body 29. An inclined arc groove 8 is provided on one side of the outer wall of the supporting threaded column 7, a slider 9 is provided inside the inclined arc groove 8, and a reserved groove 10 is reserved on the side of the slider 9 away from the inclined arc groove 8, and a limiting groove 11 is evenly provided at the bottom of the inclined arc groove 8, and an extrusion plate 12 is installed on the side of the bottom of the connecting member 6 close to the slider 9, and the extrusion plate 12 passes through the embedded box 1, and the extrusion plate 12 extends to the inside of the reserved groove 10, and a limiting rod 13 is installed on the side of the bottom of the extrusion plate 12 close to the slider 9, and the limiting rod 13 passes through the slider 9 and extends to the inside of the limiting groove 11; The extrusion plate 12 is connected to the embedded box 1 in a sliding manner, and the movable bin 4 is also connected to the embedded box 1 in a sliding manner. A certain gap is reserved between the extrusion plate 12 and the top and bottom of the reserved groove 10. The length of the limit rod 13 is less than the depth of the limit groove 11. The extrusion plate 12 and the connecting piece 6 can be fixedly connected by welding. During use, multiple groups of the components are installed at the bottom of the steel structure body 29 through the connecting piece 6. When the steel structure body 29 vibrates, the rubber block 5 will deform accordingly. At this time, the extrusion plate 12 moves up and down in the gap between the reserved groove 10 and it, so as not to hinder the rubber block 5 from deforming slightly to consume vibration energy, thereby achieving an anti-seismic effect. At the same time, when local settlement occurs, the embedded box 1 located in the local settlement part will move downward with the settlement of the ground, and the remaining embedded boxes 1 still maintain support for the steel structure main body 29. Under the rigidity of the steel structure main body 29 itself, the connecting piece 6 on the embedded box 1 located in the local settlement part will not drop, so that the corresponding extrusion plate 12 will not drop. With the occurrence of local settlement, the embedded box 1 moves downward, and the top of the extrusion plate 12 is squeezed with the top of the reserved groove 10. At the same time, the limiting rod 13 leaves the corresponding limiting groove 11, and the slider 9 and the inclined arc groove 8 form a relative sliding structure. With further settlement of the ground, the extrusion plate 12 drives the slider 9 to move relative to the inside of the inclined arc groove 8. The movable bin 4 is connected with the threaded support column 7 and the movable bin 4, and the movable bin 4 is connected with the embedded box 1, so that the movable bin 4 can move upward relative to the threaded support column 7, thereby lengthening the overall support length of the threaded support column 7 and the movable bin 4, thereby compensating for the settlement of the embedded box 1, so that the embedded box 1, the threaded support column 7, the movable bin 4, the rubber block 5 and the connecting piece 6 can still provide a certain support effect for the steel structure main body 29, thereby avoiding the situation that the group of embedded boxes 1 completely loses its supporting force, causing the remaining embedded boxes 1 to bear too much pressure, causing the steel structure main body 29 to break and collapse, etc., thereby greatly increasing the safety during use; A scale is provided at one end of the extrusion plate 12, and the extrusion plate 12 and the limit rod 13 are made in an integrated manner to ensure the strength of the extrusion plate 12 during use. At the same time, under normal use, the relative movement of the extrusion plate 12 and the embedded box 1 is kept within a certain range. When local settlement occurs, the relative movement of the extrusion plate 12 and the embedded box 1 obviously exceeds the above range. The staff can understand the specific settlement range through the scale on the extrusion plate 12, which is convenient for subsequent corresponding treatment measures; It should be noted that the bottom end of the limit rod 13 is hemispherical, and the diameter of the limit rod 13 is smaller than the inner diameter of the limit groove 11, so that in the subsequent use after settlement, the limit rod 13 can be inserted into the corresponding limit groove 11 to avoid the possible reverse rotation of the supporting threaded column 7. At the same time, during the application process, multiple groups of extrusion plates 12 can be set, and the inclined arc groove 8, limit groove 11, slider 9 and limit rod 13 used in conjunction with the extrusion plate 12 can be set in corresponding numbers. Multiple groups of extrusion plates 12 can share the extrusion force during settlement with each other, thereby ensuring its strength during use.

[0021] Embodiment 2:

[0022] Based on the above Example 1, please refer to Figure 1-Figure 3 and Fig. 9 As shown, both ends of the embedded box 1 are provided with installation windows 14, and a rubber bag 15 is installed inside the installation window 14. The inner cavity of the rubber bag 15 is connected to the movable bin 4 through a connecting pipe 16. An extrusion piece 17 is installed on the outer side of the supporting threaded column 7 near the bottom end. The cross-sectional shape of the extrusion piece 17 is elliptical, and the edges of the top and bottom of the extrusion piece 17 are rounded to avoid unnecessary cutting damage to the rubber bag 15 caused by the extrusion piece 17 when it is subsequently extruded; The rubber bag 15 can be made of corrosion-resistant rubber, which is convenient for dealing with possible corrosion under the ground. The cross-sectional shape of the movable bin 4 is rectangular, and the major axis length of the extrusion piece 17 is less than the length of the movable bin 4 and greater than the width of the movable bin 4, so that when local settlement occurs and causes the support threaded column 7 to rotate, the extrusion piece 17 can rotate accordingly. At this time, the extrusion piece 17 can squeeze and expand the rubber bag 15 outward, so that the rubber bag 15 squeezes and compacts the land around the embedded box 1, thereby greatly increasing the continuous settlement resistance of the subsequent embedded box 1, effectively reducing the risk of subsequent continued settlement; A support ring 18 is installed at the bottom of the extrusion 17, and balls 19 are evenly arranged at the bottom of the support ring 18. The extrusion 17 and the supporting threaded column 7 can be made into an integrated unit, so that the support ring 18 and the balls 19 can provide further support for the extrusion 17 and the supporting threaded column 7, thereby ensuring the strength during use. At the same time, the top of the extrusion 17 can also be provided with a part with the same function as the support ring 18 and the balls 19 without affecting other components, thereby forming an overall support for the interior of the embedded box 1, thereby increasing the overall strength of the embedded box 1 during subsequent use.

[0023] Embodiment three:

[0024] Based on the above-mentioned embodiment 1 and embodiment 2, please refer to Figure 1-Figure 4 and Figure 6As shown, a fixed plate 20 is installed inside the movable chamber 4, and a pushing mechanism for squeezing and delivering the compressed air in the movable chamber 4 to the rubber bag 15 is provided on the supporting threaded column 7. The pushing mechanism includes a connecting rod 21, which is arranged at the top end of the supporting threaded column 7 and passes through the fixed plate 20. A piston plate 22 is installed on the top of the connecting rod 21. The piston plate 22 is slidably connected to the movable chamber 4, the connecting rod 21 is slidably connected to the fixed plate 20, and the connecting rod 21 is rotatably connected to the support threaded column 7, so that when local settlement occurs and the support threaded column 7 rotates, the movable chamber 4 moves upward relative to the support threaded column 7, and the fixed plate 20 can move upward relative to the piston plate 22; There is a gap between the piston plate 22 and the fixed plate 20, and the movable chamber 4 between the piston plate 22 and the fixed plate 20 is filled with compressed air, so that the above-mentioned local settlement occurs. When the fixed plate 20 moves upward with the movable chamber 4, the compressed air between the piston plate 22 and the fixed plate 20 can be squeezed and transported to the inside of the rubber bag 15 through the connecting pipe 16, so that the rubber bag 15 itself can expand. The rubber bag 15 can be further fully compacted outwardly on the land around the embedded box 1 by the rotation of the extrusion piece 17, so as to further increase the resistance of the embedded box 1 to continuous descent; It should be noted that the cross-sectional shape of the connecting rod 21 is square, so that the connecting rod 21 will not rotate with the supporting threaded column 7, so that the piston plate 22 and the fixed plate 20 can form a stable proximity, thereby completing the extrusion and delivery of compressed gas. Furthermore, the compressed gas filled in the movable chamber 4 between the piston plate 22 and the fixed plate 20 can be replaced with a medium such as hydraulic oil without affecting the function.

[0025] Embodiment 4:

[0026] Based on the above-mentioned Embodiment 1 and Embodiment 2, please refer to Figure 1-Figure 5 and Fig.10 As shown, an annular groove 23 is provided at the top of the extrusion member 17, and a wedge-shaped groove 24 is reserved at the bottom of the annular groove 23 on the side away from the slider 9, and a mounting plate 25 is installed on the side of the embedded box 1 close to the wedge-shaped groove 24, and an extrusion rod 26 is passed through the top of the mounting plate 25, and the extrusion rod 26 extends to the inside of the mounting plate 25, and a warning member 27 is installed at the top of the extrusion rod 26, and the warning member 27 passes through the embedded box 1, and a spring 28 is connected between the warning member 27 and the mounting plate 25; The extrusion rod 26 is slidably connected to the mounting plate 25, and the warning piece 27 is slidably connected to the embedded box 1, so that when local settlement occurs and the supporting threaded column 7 rotates, the bottom end of the extrusion rod 26 and the beveled portion inside the wedge-shaped groove 24 are mutually squeezed, so that the extrusion rod 26 drives the warning piece 27 to move upward, so that the staff can timely or local settlement occurs through the protruding warning piece 27; The warning piece 27 is hexagonal, and the six sides of the warning piece 27 are all provided with warning slogans, so that the staff can intuitively see the protrusion of the warning piece 27 and the warning slogans displayed on each side from all directions. Further, the slogan can be in a more eye-catching red color, and the hexagonal nature of the warning piece 27 can be replaced with an applicable polygon without affecting the function; It should be noted that the supporting threaded column 7 can drive the warning member 27 to rise to the limit height at the initial stage of the rotation stroke. At this time, the bottom end of the extrusion rod 26 and the bottom of the annular groove 23 form mutual extrusion. During the subsequent rotation stroke of the supporting threaded column 7, the warning member 27 always remains at the limit height, thereby providing a stable warning effect at the initial stage of local settlement.

[0027] The working principle of the present invention is as follows: the ground is leveled and compacted, the embedded box 1 is embedded below the ground, and the blocking plate 3 is ensured to be in close contact with the ground, multiple sets of embedded boxes 1 are embedded in the above manner, and the steel structure main body 29 and multiple sets of connecting members 6 are installed and used. The specific installation method is the same as that of the existing similar components, which will not be repeated here; During use, when the steel structure main body 29 vibrates, the rubber block 5 can be elastically deformed accordingly, thereby consuming the vibration energy and playing the role of earthquake resistance. At the same time, the extrusion plate 12 moves in the gap inside the reserved groove 10, and the limit rod 13 moves in the corresponding limit groove 11. Therefore, in the normal use state, the limit rod 13 will not be separated from the corresponding limit groove 11, and the rotation of the support thread column 7 is restricted. The embedded box 1, the support thread column 7, the movable bin 4, the rubber block 5 and the connecting piece 6 can form a stable support for the steel structure main body 29; When local settlement occurs, the embedded box 1 located at the local settlement position will move downward under the action of settlement and gravity. At this time, the remaining components still maintain support for the steel structure main body 29. Therefore, the height of the connecting piece 6 located at the settlement position and the extrusion plate 12 thereon remains unchanged. The embedded box 1 moves downward under the action of settlement. At this time, the extrusion plate 12 is pressed against the top of the reserved groove 10, and the limiting rod 13 leaves the corresponding limiting groove 11. The sliding of the slider 9 and the inclined arc groove 8 is released. With further settlement, the extrusion plate 12 continuously squeezes the slider 9, and the slider 9 moves along the trajectory of the inclined arc groove 8, so that the support threaded column 7 rotates accordingly. Through the threaded connection between the support threaded column 7 and the movable bin 4, the movable bin 4 can move upward relative to the support threaded column 7, thereby compensating for the overall length formed by the support threaded column 7 and the movable bin 4, so that the group of support threaded columns 7 and the movable bin 4 can still maintain a certain support effect, thereby avoiding excessive deformation or even fracture and collapse of the steel structure main body 29. At the beginning of the above process, when the supporting threaded column 7 rotates, the extrusion member 17 rotates accordingly, and the beveled portion inside the wedge-shaped groove 24 can be squeezed with the extrusion rod 26, so that the extrusion rod 26 moves upward, and then the warning member 27 protrudes from the embedded box body 1, and the slogan on its outer wall promptly warns the staff; Furthermore, in the process that the supporting threaded column 7 drives the extrusion member 17 to rotate, the extrusion member 17 can squeeze and deform the rubber bag 15 outward, so that the rubber bag 15 compacts the soil layer around the embedded box 1, thereby increasing the resistance of the embedded box 1 to continue to settle, thereby reducing the possibility of subsequent accelerated settlement, and providing sufficient time for the staff to discover and deal with the problem; At the same time, in the process of the above-mentioned support threaded column 7 driving the extrusion piece 17 to rotate, the upward movement of the movable chamber 4 relative to the support threaded column 7 will cause the piston plate 22 and the fixed plate 20 to form a movement form approaching each other, so that the compressed air filled between the piston plate 22 and the fixed plate 20 can be further compressed and squeezed, and squeezed and transported to the inside of the rubber bag 15 through the connecting pipe 16. In the initial state, there can also be compressed air in the rubber bag 15, and the pressure in the rubber bag 15 is the same as the pressure between the piston plate 22 and the fixed plate 20. At this time, as the space between the piston plate 22 and the fixed plate 20 decreases, the pressure in the rubber bag 15 increases, the rubber bag 15 further expands, and then cooperates with the extrusion piece 17 to squeeze the rubber bag 15 outward, so that the rubber bag 15 can further fully compact the soil layer around the embedded box 1, thereby further increasing the compaction effect.

[0028] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
