Description

Technical Field

[0001] The present invention relates to the field of building technology, in particular to a steel structure of a building plant. Background Art

[0002] Steel structures are widely used in industrial buildings, civil buildings, bridge structures, and other construction industries due to their advantages such as high strength, good toughness, light weight, fast construction speed, and good environmental protection. Among them, a large part of steel structures are widely used in workshops and factories, but workshop and factory structures are often accompanied by some characteristics such as large size and high height.

[0003] In many areas, extreme weather phenomena such as strong winds and even typhoons frequently occur. Under such meteorological conditions, steel structures must have sufficient strength to withstand the impact of severe weather and ensure the safety and stability of the building structure.

[0004] To meet the stringent strength requirements of steel structures, current technical approaches focus on two main areas: strengthening the foundation and adding dampers. However, both approaches have significant limitations in practical application. Soft soils, with their complex geological conditions, present significant technical challenges and high construction costs, often deter builders.

[0005] In the field of steel-structured factory buildings, the addition of dampers also presents numerous challenges. Because overhead cranes and other equipment must operate at high altitudes within the factory building, there is often no structural space available for dampers, making their installation impractical. Furthermore, the manufacturing cost of the dampers themselves is extremely high, further limiting their widespread application in steel-structured factory buildings. In response to these and other challenges, the present invention was developed. Summary of the Invention

[0006] The purpose of the present invention is to provide a steel structure for a building factory, which can better withstand strong winds and has a lower manufacturing cost, thereby improving the reliability of the steel structure.

[0007] The above technical objectives of the present invention are achieved through the following technical solutions: a steel structure of a building factory, including a steel structure frame, a damping body is provided near the roof of the steel structure frame, the damping body is made of flexible material, the damping body has a downward expanded state and an upward retracted state, and a counterweight cavity is formed in the damping body, the damping body is provided with a water outlet structure, and the steel structure frame is provided with a control component that connects the damping body and is used to control the damping body to switch between the expanded state and the retracted state.

[0008] By adopting the above technical solution, the control component controls the damping body to switch to the storage state, so that the existing damping body will not interfere with equipment such as overhead cranes operating at high altitudes. When encountering strong winds or even typhoons, the control component switches the damping body from the storage state to the downwardly expanded state and injects water into the counterweight cavity. At this time, the damping body suspended on the steel structure skeleton is equivalent to the damper in the building, which is used to offset the shaking amplitude of the factory building, can effectively absorb wind energy, and protect the main structure of the factory building. When the strong wind weather is over, the water in the counterweight cavity is discharged through the water outlet structure, and then the damping body is switched to the storage state. By setting the damping body to make up for the shortcomings of the foundation strength, the structure can better withstand strong wind weather and the manufacturing cost is lower, thereby improving the reliability of the steel structure of the factory building.

[0009] It is further configured as follows: a roof is provided on the steel structure frame, a water collection trough with an upward opening is provided on the steel structure frame between the roof and the damping body, the water collection trough is connected to the counterweight cavity through a drain outlet, and a collecting port connecting the outside world and the water collection trough is provided on the roof directly above the water collection trough opening, an opening and closing structure is provided on the drain outlet, and the opening and closing structure is linked to the control component and controlled by the control component.

[0010] By adopting the above technical solution, when the control member controls the damping body to be in the stowed state, the opening and closing structure is controlled to be in the closed state. At this time, the water collection trough is used to collect rainwater. When the control member controls the damping body to switch to the deployed state, the opening and closing structure is controlled to switch to the open state, allowing rainwater in the water collection trough to be injected into the counterweight cavity through the drain port, thereby maximizing the utilization of water resources and conserving water resources. By configuring the opening and closing structure to be controlled by the control member in a linkage manner, the control of the opening and closing structure does not require the installation of an additional control device, which reduces costs and simplifies the structure, thereby reducing the failure rate of the mechanism and improving the reliability of the structure's operation.

[0011] It is further configured as follows: the control component includes a lifting component that controls the damping body to switch upward to a stored state and a limiting component that limits the damping body to switch downward to an expanded state, and the water outlet structure is linked with the control component and controlled by the control component.

[0012] By adopting the above technical solution, the lifting assembly drives the damping body to rise, allowing the damping body to rise to a high place and be stored. While the limit assembly is set to limit the damping body and bear the force on the lifting assembly to limit the damping body from falling, the service life of the lifting assembly is also extended. When the limit assembly does not limit the damping body, the lifting assembly can control the damping body to fall and unfold. When the control component controls the damping body to be in the unfolded state, the water outlet structure is controlled to be in the closed state. When the control component controls the damping body to switch from the unfolded state to the stored state, the water outlet structure is first controlled to be in the open state, which is used to discharge the water in the counterweight chamber and then switch the damping body to the stored state. By setting the water outlet structure to be linked controlled by the control component, the control of the water outlet structure does not require the setting of an additional control device, which reduces costs while also making the setting structure simpler, thereby reducing the failure rate of the mechanism and improving the reliability of the structure operation.

[0013] It is further configured as follows: the lifting assembly includes a drive motor installed on the steel structure frame and located above the water collecting tank, a drum installed on the output shaft of the drive motor, and a lifting rope wound around the drum and connected to the counterweight chamber at one end.

[0014] By adopting the above technical solution, the driving motor drives the drum to rotate so that the lifting rope is wound around the drum, thereby realizing the lifting operation of the damping body.

[0015] It is further configured as follows: the opening and closing structure is a sealing plate that is sealed to the damping body and is used to seal the drain outlet, and the lifting rope passes through the drain outlet and is connected to the sealing plate.

[0016] By adopting the above technical solution, the lifting rope simultaneously drives the sealing plate to move toward the drain outlet during the rising process. When the sealing plate is pressed against the bottom of the drain outlet, the sealing operation of the drain outlet is achieved, thereby realizing the linkage control between the control component and the opening and closing structure.

[0017] It is further configured as follows: the water outlet structure includes a water outlet pipe connected to the sealing plate, a connecting channel provided on the sealing plate and used to connect the counterweight chamber and the water outlet pipe, and a linkage sealing block movably provided in the water outlet pipe, the lifting rope passes through the drain outlet and the connecting channel in turn and is connected to the linkage sealing block, the water outlet pipe includes a water flow section connected to the sealing plate and a sealing section connected to the water flow section, the linkage sealing block is slidably provided in the water flow section and can allow water to flow through, when the linkage sealing block moves toward the sealing plate, the connecting channel is sealed; when the linkage sealing block moves toward the sealing section, the sealing section is sealed.

[0018] By adopting the above technical solution, when the damping body is in the expanded state, the lifting rope is in the relaxed state, allowing the linkage sealing block to move downward under the action of gravity and water pressure and seal the sealing section to prevent the water in the counterweight chamber from being discharged outward through the outlet pipe. When the water in the counterweight chamber needs to be discharged, the lifting rope lifts the linkage sealing block upward to allow the linkage sealing block to leave the sealing section. At this time, the water in the counterweight chamber can be discharged outward through the connecting channel through the water flow section and the sealing section. After completing the drainage operation, the lifting rope drives the linkage sealing block to move upward, and the connecting channel is sealed by the linkage sealing block, so as to ensure the sealing function of the sealing plate for the drain outlet, and realize the linkage control between the control component and the water outlet structure.

[0019] It is further configured as follows: a guide protrusion is provided on the side of the sealing plate facing the drain outlet to guide the sealing plate to seal the drain outlet, the guide protrusion extends away from the side of the sealing plate and gradually shrinks to form a cone, and the connecting channel is coaxially arranged with the guide protrusion and passes through the guide protrusion.

[0020] By adopting the above technical solution, the guide protrusion moves toward the drain outlet along with the sealing plate. When the guide protrusion passes through the drain outlet, the position of the sealing plate is limited so that the sealing plate can be stably limited directly below the drain outlet, thereby ensuring the stable sealing of the drain outlet by the sealing plate structure, thereby improving the feasibility and reliability of the setting structure.

[0021] It is further configured as follows: the limit assembly includes a limit block that moves with the lifting rope, a check block that is slidably arranged on the steel structure frame and located on one side of the lifting rope movement path, a positioning spring that drives the check block to move toward one side of the lifting rope, a pull rope that drives the check block to move away from the lifting rope, and a guide slope formed on the check block and for the limit block to pass through the check block. When the check block is against the limit block to restrict the downward movement of the lifting rope, the opening and closing structure is in a closed state.

[0022] By adopting the above technical solution, the lifting rope drives the limit block to move. The guide slope allows the limit block to easily pass the check block. The check block then abuts against the limit block to restrict the downward movement of the lifting rope, thereby achieving the purpose of limiting the lifting assembly. The limit assembly can also bear the force on the drive motor, thereby extending the service life of the drive motor. By pulling the pull rope to drive the check block to move away from the lifting rope, the limit imposed by the limit block can be released, thereby achieving the unlocking operation.

[0023] It is further configured as follows: the outer wall of the damping body is connected to a number of flattening ropes for pulling the damping body outward, and each of the flattening ropes is provided with a return spring connected to the steel structure frame at one end facing away from the damping body, and each of the return springs is arranged on the outside of the damping body, and a number of reinforcing ropes are connected between the water collecting tank and the damping body.

[0024] By adopting the above technical solution, when rainwater in the sump flows into the counterweight chamber, the damping body drives the flattening rope downward and pulls the reset spring into a stretched state. When the damping body switches from the expanded state to the stored state, the reset spring resets and pulls the damping body outward and flattened through the flattening rope, thereby reducing the drooping height of the damping body in the stored state, playing a better storage role, and avoiding interference with other equipment and damage to the damping body. In addition, by pulling the damping body outward and flattening it during the folding process, it can be avoided that the damping body is partially clamped between the sealing plate and the sump during the folding process, thereby affecting the effective sealing of the sealing plate for the drain outlet.

[0025] It is further configured as follows: a water pump is provided in the water collecting tank, a plurality of cooling nozzles are arranged on the roof, an outlet of the water pump is connected to a water outlet pipe, and the water outlet pipe is connected to each cooling nozzle.

[0026] By adopting the above technical solution, the water pump transports the rainwater in the water collection tank into the water outlet pipe and sprays it out through the cooling nozzle to cool the roof, giving the water collection tank multiple functions.

[0027] In summary, the present invention has the following beneficial effects: the present invention can better withstand strong wind weather and has a lower manufacturing cost, thereby improving the reliability of the steel structure of the factory building. BRIEF DESCRIPTION OF THE DRAWINGS
