Description

Technical Field

[0001] The present 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 of steel structure, a variety of accessories are needed to cooperate with each other. Steel structure load-bearing components are one of them. During the construction process, multiple groups of steel structure load-bearing components are generally installed at the bottom of the steel structure body to achieve stable support assembly of the steel structure.

[0003] When existing steel structure load-bearing components are used, 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, due to the complexity and diversity of the environment during actual use, 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 local ground sinking occurs, 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, and in severe cases even causing the steel structure to break and collapse, thereby greatly affecting its safety.

[0020] Beneficial effects of the present invention:

[0021] (1) The present invention connects the supporting threaded column and the movable chamber by threading, and the supporting threaded column is provided with an inclined arc groove for cooperating with the slider, and the connecting piece is provided with an extrusion plate, so that when local settlement occurs, the embedded box will move downward with the settlement, and the slider will slide in the inclined arc groove correspondingly through the extrusion plate, so that the supporting threaded column will rotate accordingly. At this time, the movable chamber moves upward to compensate for the reduction in the overall length caused by the settlement, so that the supporting threaded column and the movable chamber can still maintain support for the main body of the steel structure, avoiding excessive pressure on the remaining supporting parts, which may cause the main body of the steel structure to break and collapse;

[0022] (2) The present invention provides a rubber block between the movable compartment and the connecting piece, and provides a gap between the extrusion plate and the top and bottom of the reserved groove, so that when the steel structure body vibrates, the rubber block can be deformed accordingly to consume the vibration energy, thereby achieving an anti-seismic effect;

[0023] (3) The present invention provides a rubber bag in the installation window and an extrusion piece on the support thread column, so that when the support thread column rotates due to local settlement, the extrusion piece can rotate accordingly and squeeze the rubber bag outward to deform, thereby allowing the rubber bag to compact the surrounding soil of the embedded box, increase the friction required to resist further sinking, and thus effectively reduce further settlement;

[0024] (4) The present invention fills the movable chamber between the fixed plate and the piston plate with compressed air, and the movable chamber is connected to the rubber bag, so that when local settlement occurs and the movable chamber drives the fixed plate to move upward, the fixed plate can move toward the piston plate, and then the fixed plate can cooperate with the piston plate to further squeeze the compressed air into the rubber bag, causing the rubber bag to expand and expand outward with the help of the extrusion part, so as to further achieve the compaction of the surrounding area of the embedded box and the embedded land;

[0025] (5) The present invention provides an annular groove and a wedge-shaped groove on the extrusion member, and provides an extrusion rod and a warning member on the mounting plate, so that when local settlement occurs and causes the supporting threaded column to rotate, the extrusion rod will be squeezed to drive the warning member to move upward, and this process occurs in the initial stage of the rotation of the supporting threaded column. As a result, in the initial stage of local settlement, the warning member can protrude from the embedded box to promptly alert the staff, so that the staff can discover it in time and make reasonable responses.

DETAILED DESCRIPTION

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making any creative efforts shall fall within the scope of protection of the present invention.

[0040] Example 1:

[0041] See also Figures 1-8 as well as Figure 11 As shown, an earthquake-resistant steel structure load-bearing member includes an embedded box body 1, a movable chamber 4 is passed through the top of the embedded box body 1, a rubber block 5 is installed on the top of the movable chamber 4, and a connector 6 is installed on the top of the rubber block 5, and a support thread column 7 is provided at the bottom of the embedded box body 1, and the support thread column 7 passes through the bottom end of the movable chamber 4;

[0042] 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 buried 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.

[0043] The outer wall of the embedded box 1 is evenly installed with threaded steel bars 2, and the side walls of the embedded box 1 are installed with blocking plates 3;

[0044] The above-mentioned threaded steel 2 can be installed on the embedded box 1 by welding, and the blocking plate 3 can be made into an integrated part with the embedded box 1. The threaded steel 2 can be provided in multiple groups according to actual needs, and the outer wall of the threaded steel 2 can also be coated with a corrosion-resistant coating. During application, the threaded steel 2 can be embedded below the ground along with the embedded box 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.

[0045] The supporting threaded column 7 is connected to the embedded box 1 in a rotational manner, and the supporting threaded column 7 is connected to the movable chamber 4 in a threaded manner;

[0046] The above-mentioned support threaded column 7 and the embedded box body 1 can be connected by a giant thrust bearing to ensure the supporting force of the support threaded column 7 itself. During application, the support threaded column 7 and the movable chamber 4 are threadedly connected, so that the support threaded column 7 and the movable chamber 4 can effectively provide an upward supporting force. At the same time, the embedded box body 1 provides an upward supporting force for the support threaded column 7, thereby enabling the component to effectively support the steel structure main body 29.

[0047] An inclined arc-shaped 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-shaped groove 8, and a reserved groove 10 is reserved on the side of the slider 9 away from the inclined arc-shaped groove 8, and a limiting groove 11 is evenly provided on the bottom of the inclined arc-shaped groove 8. 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 extends to the inside of the reserved groove 10. 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;

[0048] The above-mentioned extrusion plate 12 is slidably connected to the embedded box body 1, and the movable bin 4 is also slidably connected to the embedded box body 1. A certain gap is reserved between the extrusion plate 12 and the top and bottom of the reserved groove 10. The length of the limiting rod 13 is less than the depth of the limiting groove 11. The extrusion plate 12 and the connecting piece 6 can be fixedly connected by welding. During use, multiple groups of these 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, thereby not hindering the rubber block 5 from deforming slightly to consume vibration energy, thereby achieving an anti-seismic effect.

[0049] 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 will 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. As local settlement occurs, 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. As the ground further settles, the extrusion plate 12 drives the slider 9 to move relative to the inside of the inclined arc groove 8. The cam 4 is connected to the movable chamber 4 by the threaded connection between the cam 4 and the embedded box 1, so that the movable chamber 4 can move upward relative to the cam 4, thereby lengthening the overall support length of the cam 4 and the embedded box 1, thereby compensating for the settlement of the embedded box 1, so that the embedded box 1, the cam 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 complete loss of support force of the group of embedded boxes 1, causing excessive pressure on the remaining embedded boxes 1, resulting in the fracture and collapse of the steel structure main body 29, etc., thereby greatly increasing the safety during use;

[0050] One end of the extrusion plate 12 is provided with a scale, and the extrusion plate 12 and the limit rod 13 are made in one piece 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.

[0051] 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 during 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.

[0052] Example 2:

[0053] Based on the above Example 1, please refer to Figure 1-Figure 3 and Figure 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 chamber 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-section of the extrusion piece 17 is elliptical, and the edges of the top and bottom of the extrusion piece 17 are rounded to prevent the extrusion piece 17 from causing unnecessary cutting damage to the rubber bag 15 when it is subsequently squeezed;

[0054] The rubber bag 15 can be made of corrosion-resistant rubber, which is convenient for dealing with possible corrosion under the ground. The cross-section of the movable chamber 4 is rectangular, and the major axis length of the extrusion member 17 is less than the length of the movable chamber 4 and greater than the width of the movable chamber 4, so that when local settlement causes the support threaded column 7 to rotate, the extrusion member 17 can rotate accordingly. At this time, the extrusion member 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 subsequent continuous settlement resistance of the embedded box 1, effectively reducing the risk of subsequent continued settlement;

[0055] A support ring 18 is installed at the bottom of the extrusion 17, and balls 19 are evenly arranged on 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.

[0056] Example 3:

[0057] Based on the above examples 1 and 2, please refer to Figures 1-4 and Figure 6 As shown, a fixed plate 20 is installed inside the movable chamber 4, and a pushing mechanism for squeezing the compressed air in the movable chamber 4 into the rubber bag 15 is provided on the supporting threaded column 7. The pushing mechanism includes a connecting rod 21, which is provided at the top 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.

[0058] 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;

[0059] 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, which causes the above-mentioned local settlement. As 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, thereby causing the rubber bag 15 itself to expand. The rotation of the extrusion piece 17 to squeeze the rubber bag 15 can further fully compact the ground around the embedded box 1, thereby further increasing the resistance of the embedded box 1 to continued descent.

[0060] 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.

[0061] Example 4:

[0062] Based on the above examples 1 and 2, please refer to Figure 1-Figure 5 and Figure 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 on the side of the bottom of the annular groove 23 away from the slider 9. A mounting plate 25 is installed on the side of the embedded box 1 close to the wedge-shaped groove 24. An extrusion rod 26 passes through the top of the mounting plate 25, and the extrusion rod 26 extends to the inside of the mounting plate 25. A warning member 27 is installed on the top of the extrusion rod 26, and the warning member 27 passes through the embedded box 1. A spring 28 is connected between the warning member 27 and the mounting plate 25.

[0063] 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 oblique edge portion inside the wedge-shaped groove 24 are squeezed against each other, thereby causing the extrusion rod 26 to drive the warning piece 27 to move upward, so that the staff can timely or local settlement through the protruding warning piece 27;

[0064] The warning member 27 is hexagonal, and warning slogans are provided on all six sides of the warning member 27, so that the staff can intuitively see the protrusion of the warning member 27 and the warning slogans displayed on each side from all directions. Furthermore, the slogans can be in a more eye-catching red color. At the same time, the hexagonal shape of the warning member 27 can be replaced with a suitable polygon without affecting the function.

[0065] 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.

[0066] 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-mentioned manner, and the steel structure main body 29 and multiple sets of connecting parts 6 are installed and used. The specific installation method is the same as that of existing similar components and will not be repeated here.

[0067] During use, when the steel structure main body 29 vibrates, the rubber block 5 can correspondingly undergo elastic deformation, thereby consuming the vibration energy and playing a role in earthquake resistance. At the same time, the extrusion plate 12 moves correspondingly in the gap inside the reserved groove 10, and the limiting rod 13 moves correspondingly inside the corresponding limiting groove 11. Therefore, under normal use, the limiting rod 13 will not be separated from the corresponding limiting groove 11, and the rotation of the supporting threaded column 7 is restricted. The embedded box 1, the supporting threaded 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;

[0068] When local settlement occurs, the embedded box body 1 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 at the settlement position and the extrusion plate 12 thereon remains unchanged, and the embedded box body 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, and the sliding of the slider 9 and the inclined arc groove 8 is released. With further settlement, the extrusion plate 12 continues to squeeze the slider 9, and the slider 9 moves along the trajectory of the inclined arc groove 8, causing the supporting threaded column 7 to rotate accordingly. Through the threaded connection between the supporting threaded column 7 and the movable chamber 4, the movable chamber 4 can now move upward relative to the supporting threaded column 7, thereby compensating for the overall length formed by the supporting threaded column 7 and the movable chamber 4, so that the group of supporting threaded columns 7 and the movable chamber 4 can still maintain a certain supporting effect, thereby preventing the steel structure main body 29 from being excessively deformed or even broken and collapsed;

[0069] At the beginning of the above process, when the supporting threaded column 7 rotates, the extrusion member 17 rotates accordingly, and the oblique edge portion inside the wedge-shaped groove 24 can form an extrusion with the extrusion rod 26, causing the extrusion rod 26 to move upward, thereby causing the warning member 27 to protrude from the embedded box 1 and promptly warn the staff through the slogan on its outer wall;

[0070] Furthermore, in the process of the support threaded column 7 driving the extrusion member 17 to rotate, the extrusion member 17 can squeeze the rubber bag 15 outward and deform it, 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 further settlement, thereby reducing the possibility of subsequent accelerated settlement, and providing sufficient time for staff to discover and deal with the problem;

[0071] 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 close to 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, compressed air can also exist 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.

[0072] The above is a detailed description of an embodiment of the present invention. However, the content described is only a preferred embodiment of the present invention and should not be considered to limit the scope 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.
