Description

Technical Field

[0001] The invention belongs to the technical field of steel structures, and in particular relates to a Y-shaped column structure for steel structure construction. Background Art

[0002] Steel structures are mainly constructed of steel, which has significant advantages such as high strength, good toughness and strong plasticity. At the same time, steel structures can easily withstand large loads and achieve large spans. In addition, steel structures have the characteristics of fast construction speed and can be completed in a short time, greatly reducing the adverse impact on traffic and the surrounding environment. At the same time, its relatively light weight also reduces the requirements for the lower foundation. Therefore, most of the pedestrian overpass buildings in cities currently use steel structures, and in order to ensure the stability of the pedestrian overpass structure, the steel structure of this type of pedestrian overpass is usually supported by Y-shaped columns. Y-shaped columns can more effectively disperse the load of the overpass, thereby significantly improving the overall stability of the pedestrian overpass.

[0003] At present, most Y-shaped columns of steel structure pedestrian bridges adopt an integrated welded structure. This type of Y-shaped column has the following defects when used:

[0004] First, the Y-shaped column of the steel structure pedestrian bridge has poor buffering performance. When a large number of people pass through the pedestrian bridge, a large dynamic load will be generated. As the use time increases, the metal fatigue of the Y-shaped column continues to increase, which is very likely to cause damage to the column, and then have an adverse effect on the reliability of its support;

[0005] Second, the Y-shaped column has limited ability to adjust thermal expansion and contraction. In high or low temperature environments, the integrated Y-shaped column is difficult to effectively compensate for the stress changes caused by thermal expansion and contraction, which can easily lead to cracking and damage of the column, affecting its service life and reliability.

[0006] Third, the current Y-type column does not have the ability to alarm for overweight. If too many people pass through at the same time, the load-bearing capacity of the Y-type column will be exceeded, which may easily cause the Y-type column to deform and be damaged, further affecting the service life and reliability of the Y-type column.

[0007] Therefore, we propose a Y-column structure for steel structure construction to solve the above problems. Summary of the invention

[0019] Compared with the existing technology, the advantages of a Y-shaped column structure for steel structure construction are:

[0020] 1. Through the setting of the adjustment mechanism, Y-type column body and column cap, when multiple Y-type column structures are used to support the construction of the steel structure pedestrian bridge, the Y-type column structure is first stably installed in the concrete foundation through the steel base, the limiting convex plate and the limiting frame, and then the upper surfaces of the column caps of the multiple Y-type column structures are placed in the same horizontal installation position through the adjustment mechanism, which can not only reduce the interference of dimensional errors caused by the assembly of the Y-type column structure, but also reduce the interference of errors caused by the construction of the steel structure concrete foundation. This mechanism enables the Y-type column structure in the steel structure to have the function of installation and adjustment, which can effectively avoid the error interference caused by the construction process of the Y-type column structure, improve the reliability of the use of the Y-type column structure, and effectively improve the convenience of steel structure construction.

[0021] 2. Through the dynamic load buffer mechanism, when pedestrians pass through the steel structure pedestrian bridge, their movement will form a dynamic load in the pedestrian bridge. The dynamic load is transmitted to the dynamic load buffer mechanism through the column cap and the Y-type column body. The rubber buffer damper of the dynamic load buffer mechanism can damp and buffer the dynamic load. In addition, the dynamic load buffer mechanism can also cooperate with the micro DC generator in the overload alarm mechanism to generate electricity while buffering. The electricity is transmitted to the battery for standby. The power of the battery can provide power support for the overload alarm mechanism. This mechanism enables the Y-type column structure in the steel structure to have the function of dynamic load buffering, effectively reducing the metal fatigue damage caused by the dynamic load to the Y-type column structure, and can effectively improve the reliability and life of the Y-type column structure.

[0022] 3. Through the overload alarm mechanism, if a large number of pedestrians pass through the steel structure pedestrian bridge at the same time, causing the Y-type column structure to exceed the load limit, the telescopic pressure sensor in the overload alarm mechanism will be squeezed by the thick steel cover that moves downward. The telescopic pressure sensor can detect the load-bearing capacity of the Y-type column body and convert the load-bearing capacity into an electrical signal and transmit it to the PLC controller. Then the PLC controller controls the sound and light alarm to send out a sound and light alarm, and reminds pedestrians on the steel structure pedestrian bridge to divert, avoiding injuries caused by too many pedestrians on the steel structure. This mechanism enables the Y-type column structure in the steel structure to have the function of overload alarm, avoiding deformation and damage of the Y-type column structure due to overload, and can effectively improve the reliability and life of the Y-type column structure in the steel structure.

[0023] 4. Through the dynamic load buffer mechanism and hollow sealing rubber ring, in high or low temperature environment, the change of ambient temperature can cause the Y-type column structure in the steel structure to expand and contract. At this time, the deformation of the dynamic load buffer mechanism and the hollow sealing rubber ring can compensate for the thermal expansion and contraction, avoiding the stress damage caused by the thermal expansion and contraction of the Y-type column structure in the steel structure. This mechanism enables the Y-type column structure in the steel structure to have the function of compensating for thermal expansion and contraction, avoiding the damage of the Y-type column structure due to thermal expansion and contraction, and improving the service life and reliability of the Y-type column structure.

[0033] The top of the metal moving block 5 is fixedly connected to a dynamic load buffer mechanism 8, and the top of the dynamic load buffer mechanism 8 is fixedly connected to the top inner wall of the thick steel cover 3. The dynamic load buffer mechanism 8 includes multiple telescopic rods 81 and rubber buffer dampers 82 fixedly connected to the upper surface of the metal moving block 5, and the interiors of the multiple rubber buffer dampers 82 are provided with buffer cavities 14 for dynamic load buffering. The buffer cavity 14 can improve the buffering effect of the rubber buffer damper 82, and the tops of the multiple telescopic rods 81 and the rubber buffer dampers 82 are fixedly connected to the top inner wall of the thick steel cover 3. The top side wall of the thick steel cover 3 is provided with multiple through holes, and the hole wall of the through hole is fixedly connected with an air intake check valve 83. The top of the thick steel cover 3 is fixedly embedded with an air duct 84, and the top of the air duct 84 passes through the outer wall of the Y-shaped column body 1. This mechanism can buffer the damage to the Y-shaped column structure caused by dynamic load and thermal expansion and contraction.

[0034] The outer wall of the Y-shaped column body 1 is fixedly connected with a load-exceeding alarm mechanism 9, which includes a sealed shell 91 fixedly connected with the outer wall of the Y-shaped column body 1, and the sealed shell 91 and the outer wall of the Y-shaped column body 1 together form a sealed installation cavity 92, the top outer wall of the conduit 71 is fixedly sleeved with an arc cover 93, the bottom outer wall of the arc cover 93 is fixedly connected with the outer wall of the Y-shaped column body 1, the air outlet end of the air guide pipe 84 is located on the inner side of the air guide cover, and the outer wall of the arc cover 93 is fixedly connected with a branch pipe 94, the top of the branch pipe 94 is fixedly connected to a first one-way jet valve 95, the outer wall of the Y-shaped column body 1 is fixedly connected to a connecting frame 96, a micro DC generator 97 is embedded at the top height of the connecting frame 96, a fan blade 98 is fixedly connected to the rotating end of the micro DC generator 97, and the fan blade 98 is located just above the first one-way jet valve 95, the inner wall of the sealed housing 91 is fixedly connected to a PLC controller 99 and a battery 910, the outer wall of the sealed housing 91 is fixedly connected to an audible and visual alarm 911, and the connection The outer wall of the frame 96 is fixedly connected with a flow stabilizing module 912, which includes a rectifier, a voltage stabilizer and a micro filter. The flow stabilizing module 912 can process the power generated by the micro DC generator 97 to ensure that the power can be stably and reliably transmitted to the battery 910 for storage and standby. The upper surface of the metal moving block 5 is fixedly connected with a telescopic pressure sensor 913, and the top of the telescopic pressure sensor 913 contacts the top inner wall of the thick steel cover 3. The top of the sealed shell 91 is fixedly connected with a second one-way jet valve 914. The outer wall of the sealed shell 91 is provided with a rectangular maintenance hole, and the hole wall of the rectangular maintenance hole is sealed with a cover plate 12. The outer wall of the cover plate 12 is fixedly connected to the sealed shell 91 by bolts. The top of the sealed shell 91 is provided with a threaded hole for hydraulic oil compensation in the adjustment mechanism 7, and the hole wall of the threaded hole is threadedly sealed with a sealing plug 13. This mechanism enables the Y-type column structure in the steel structure to have the function of overload alarm to avoid deformation and damage of the Y-type column structure due to overload.

[0035] The inner walls of the Y-shaped column body 1 and the two column caps 2 are fixedly connected with a reinforcing cage 15, and the bottom end of the reinforcing cage 15 is fixedly connected to the upper surface of the thick steel cover 3. The reinforcing cage 15 can improve the structural strength of the Y-shaped column body 1 and the two column caps 2, and improve the reliability of the Y-shaped column structure.

[0036] The output end of the micro DC generator 97 is electrically connected to the battery 910 through a current stabilizing module 912, the telescopic pressure sensor 913 is electrically connected to the input end of the PLC controller 99 through a wire, the sound and light alarm 911 is electrically connected to the output end of the PLC controller 99 through a wire, and the battery 910 can provide reliable power support. When an object applies pressure to the telescopic pressure sensor 913, the elastic element in the telescopic pressure sensor 913 will be deformed, and the strain gauge is attached to the elastic element. As the elastic element is deformed, strain is generated, and the resistance value of the strain gauge will change with the size of the strain. By measuring the resistance change of the strain gauge, the size of the pressure applied by the object can be determined. Finally, the resistance change inside the telescopic pressure sensor 913 is transmitted to the PLC controller 99 in the form of an electrical signal. The above-mentioned power-on equipment and electrical connections are all existing technologies and will not be repeated here.

[0037] The operating principle of the present invention is described as follows: when multiple Y-shaped column structures are used to support the construction of a steel structure pedestrian bridge, the Y-shaped column structure is first stably connected to the concrete foundation through the steel base 11, the limiting convex plate 16 and the limiting frame 17. After the concrete solidifies, the hydraulic oil layer 74 is injected into the bottom cavity of the thick support frame 10 through the replenishing valve 73, the conduit 71 and the oil check valve 72. As the liquid level of the hydraulic oil layer 74 rises, the hydraulic oil layer 74 adjusts the height of the Y-shaped column body 1 through the sealing cover 6, the metal moving block 5, the thick steel cover 3 and the dynamic load buffer mechanism 8. The thick steel cover 3 is in the limiting frame 17. The position is adjusted and the upper surfaces of the column caps 2 of the multiple Y-column structures are placed in the same horizontal installation position. This can not only reduce the interference of dimensional errors caused by the assembly of the Y-column structure, but also reduce the interference of errors caused by the construction of the steel structure concrete foundation, thereby ensuring that the crossbeam part of the steel structure pedestrian bridge can be accurately and smoothly connected to the top of the Y-column structure. This mechanism enables the Y-column structure in the steel structure to have the function of installation and adjustment, which can effectively avoid the error interference caused during the construction of the Y-column structure, improve the reliability of the use of the Y-column structure, and effectively improve the convenience of steel structure construction.

[0038] When pedestrians pass through the steel structure pedestrian bridge, their movement will form a dynamic load in the pedestrian bridge, and the dynamic load will be transmitted to the dynamic load buffer mechanism 8 through the column cap 2 and the Y-shaped column body 1. At this time, the dynamic load will push the thick steel cover 3 to move downward, and the downward movement of the thick steel cover 3 will squeeze the telescopic rod 81 to contract. The multiple telescopic rods 81 can ensure that there will be no lateral displacement between the thick steel cover 3 and the metal moving block 5, and constrain the freezing buffer mechanism to perform buffering in the vertical direction. When the telescopic rod 81 contracts, the thick steel cover 3 will squeeze the rubber buffer damper 82 to deform, and the buffer cavity 14 is used to ensure the buffering effect of the rubber buffer damper 82. The rubber molecular chains of 82 are curled and tangled. When deformed by external force, the rubber molecular chains stretch, twist or slide, overcome the intermolecular friction and cohesion and consume energy. When unloading, the rubber molecular chains recover slowly and cannot completely release energy. The unreleased part dissipates as heat energy, generating damping. At the same time, the microstructural defects and unevenness inside the rubber, such as pores, impurities, and crystallized areas, lead to local stress concentration and irregular movement of the molecular chains during deformation, generating internal friction, converting mechanical energy into heat energy, further increasing damping consumption, ensuring the effect of the rubber buffer damper 82 in buffering dynamic loads, and ensuring the safety and reliability of the Y-column structure in the steel structure.

[0039] In addition, when the dynamic load buffering mechanism 8 is working, the metal moving block 5 cooperates with the sealing cover 6 to move up and down in the thick limit frame 17, and forms a manual air pump. During the up and down movement of the metal moving block 5 and the sealing cover 6, air is sucked through the air intake check valve 83 and exhausted through the air duct 84. The air enters the arc cover 93 through the air duct 84, and is sprayed to the fan blades 98 through the branch pipe 94 and the first one-way jet valve 95 in the arc cover 93. The small aperture of the branch pipe 94 can increase the pressure of the air sprayed from the first one-way jet valve 95, and the high-pressure airflow can drive the fan blades 98 to rotate quickly and reliably. The rotation of the fan blades 98 can drive the micro DC generator 97 to rotate and generate electricity, and the generated electricity is then transmitted to the battery 910 for standby. The electricity of the battery 910 can provide power support for the operation of the overload alarm mechanism 9. This mechanism enables the Y-type column structure in the steel structure to have the function of dynamic load buffering, effectively reducing the metal fatigue damage caused by the dynamic load to the Y-type column structure, and can effectively improve the reliability and life of the Y-type column structure.

[0040] If a large number of pedestrians pass through the steel structure at the same time, causing the Y-column structure to exceed the load limit, the bearing capacity of the Y-column body 1 subjected to the overload will act on the dynamic load buffer mechanism 8 through the thick steel cover 3. At this time, the telescopic rod 81 and the rubber buffer damper 82 will be compressed to the maximum extent. At the same time, the telescopic pressure sensor 913 is squeezed by the thick steel cover 3 that moves downward. The telescopic pressure sensor 913 can detect the bearing capacity of the Y-column body 1 and convert the bearing capacity into an electrical signal and transmit it to the PLC controller 99. After the bearing capacity detected by the telescopic pressure sensor 913 reaches the maximum bearing capacity of the Y-column preset by the PLC controller 99, the PLC controller 99 controls the sound and light alarm 911 to emit a sound and light alarm, and reminds pedestrians on the steel structure pedestrian overpass to divert, so as to avoid injuries caused by too many pedestrians on the steel structure. This mechanism enables the Y-column structure in the steel structure to have the function of overload alarm, so as to avoid deformation and damage of the Y-column structure due to overload, and can effectively improve the reliability and life of the Y-column structure in the steel structure.

[0041] In a high or low temperature environment, changes in ambient temperature can cause the Y-type column structure in the steel structure to expand and contract due to thermal expansion. At this time, the Y-type column structure in the steel structure can compensate for the dimensional changes of the Y-type column structure caused by thermal expansion and contraction through the buffer stroke of the dynamic load buffer mechanism 8. At the same time, the deformation of the hollow sealing rubber ring 4 can also compensate for the thermal expansion and contraction of the thick steel cover 3 and the thick support frame 10, thereby avoiding stress damage to the Y-type column structure in the steel structure caused by thermal expansion and contraction. This mechanism enables the Y-type column structure in the steel structure to have the function of compensating for thermal expansion and contraction, thereby avoiding damage to the Y-type column structure due to thermal expansion and contraction, and improving the service life and reliability of the Y-type column structure.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
