Description

Technical Field

[0001] The invention relates to the technical field of factory building construction, and in particular to an earthquake-resistant structure based on a steel structure factory building. Background Art

[0002] As an important part of the modern construction industry, steel structure factories are widely welcomed for their advantages such as short construction period, relatively low cost and high structural flexibility. Especially in the field of industrial construction, steel structure factories are often used in manufacturing workshops, warehousing and logistics and other places because they can provide large-span space.

[0003] The main function of a steel structure workshop is to provide a large space, column-free internal environment to meet the needs of various industrial activities. Its design usually takes into account the following points: large span space, steel structure workshop can easily achieve large span design to meet the needs of equipment layout and material transportation, flexible layout, the internal space can be freely divided and the layout can be adjusted according to needs, adapting to the changes in different production processes, fast construction, due to the high level of prefabrication of steel structure components, on-site construction is mainly assembly work, fast construction speed, sustainability, steel is recyclable, in line with the sustainable development concept of modern architecture.

[0004] Although steel structure factories have many advantages, they still have some shortcomings in earthquake and wind resistance. The steel itself has good ductility, but under the action of earthquakes, large-span structures are prone to large vibrations, leading to structural fatigue and damage. Since steel structure factories are usually tall and have large spans, the influence of wind loads is significant, especially in typhoon-prone areas. The lateral stiffness and overall stability of the factory may be insufficient, which can easily cause shaking or local instability. Summary of the invention

[0005] In order to improve the earthquake resistance and wind resistance of steel structure factory buildings and reduce fatigue damage to the factory building structure, the present invention provides an earthquake-resistant structure based on the steel structure factory building.

[0006] The present invention provides an earthquake-resistant structure based on a steel structure factory building, which adopts the following technical solutions: A seismic-resistant structure based on a steel structure factory building, comprising a main structure, a seismic-resistant support structure and a seismic-resistant buffer structure, wherein the seismic-resistant support structure is installed on the main structure and supports the main structure, the seismic-resistant buffer structure is installed at the connection nodes on the main structure and buffers the vibration conduction at the nodes, an air duct structure is arranged on the main structure, a ground cushion layer is arranged at the bottom of the main structure, the seismic-resistant support structure comprises a support frame, a pull rod and a keel frame, the support frame is installed on the main structure in an interval arrangement, one end of the pull rod is connected and installed on the support frame, and the other end is pulled on the ground, and the keel frame is arranged on the surface of the main structure and is interconnected with the support frame.

[0007] By installing seismic support structures and seismic buffer structures on the main structure, the seismic resistance of the overall structure is improved. The combination of support frames, tension rods and keel frames can effectively disperse and transfer seismic loads and reduce direct impacts on the main structure. The seismic buffer structure provides additional buffering capacity at the connection nodes to reduce the impact of vibration transmission to the main structure, which not only protects the structure itself, but also improves the safety of internal equipment and personnel. Through reasonable structural layout, seismic support structures and seismic buffer structures enhance the stiffness and stability of the overall structure, especially under earthquake and strong wind conditions, to ensure the safety of the factory building. The design of the air duct structure and ground cushion further improves the comfort and foundation stability of the factory building. The air duct structure optimizes the air flow and noise reduction effects, while the ground cushion provides a good foundation support for the factory building.

[0008] Furthermore, the support frame includes an outer steel beam, a supporting outer column and a telescopic sleeve rod, the outer steel beam is installed on the top surface of the main structure, the supporting outer column is installed on one side of the side wall of the main structure, the top of the supporting outer column is connected to the outer steel beam, the telescopic sleeve rod is installed at the bottom of the supporting outer column and controls the height of the supporting outer column by telescoping, the pulling rod is a telescopic structure, bolt joints are respectively provided at both ends of the pulling rod, the bolt joint at the lower end of the pulling rod is connected to a ground nail, the ground nail is buried under the ground, the bolt joint at the upper end of the pulling rod is connected to a pulling clamp, and the pulling clamp is installed on the outer steel beam, the keel frame includes a main keel, a vertical keel and a combined buckle, the main keel is horizontally arranged and vertically arranged on the inner surface of the wall of the main structure, the vertical keel is vertically arranged and horizontally arranged on the inner surface of the wall of the main structure, the vertical keel and the main keel are cross-connected to each other to form a mesh structure, and a combined buckle is provided at the connection point of the main keel and the vertical keel.

[0009] Through the close connection between the outer steel beam and the supporting outer column, and the height adjustability of the telescopic sleeve, the support frame can effectively absorb and disperse the vibration energy in an earthquake and reduce the impact on the main structure. The adjustability of the telescopic sleeve and the pull rod makes the entire support system highly flexible and can be adjusted according to site conditions and needs to adapt to different building requirements and geological conditions. The connection between the pull rod and the ground nail provides additional ground fixing support to ensure that the support frame remains stable under external forces such as earthquakes or strong winds, reducing the risk of tilting or collapse. The use of combined buckles simplifies the connection between the main keel and the vertical keel, making the installation process faster and more convenient for future inspection and maintenance, reducing construction and maintenance costs. The mesh design of the keel frame not only enhances the structural strength of the wall, but also provides support and fixing points for the installation of internal facilities, improving the flexible utilization of space. The design of the entire support frame system provides multiple guarantees through multi-point connection and multi-layer protection, improving the safety of buildings in natural disasters such as earthquakes.

[0010] Furthermore, the main structure includes a steel structure support and a structural steel plate. The steel structure support is arched and arranged flat on the ground. The structural steel plate is installed and attached to the outer surface of the steel structure support to form a closed building structure.

[0011] The arched steel structure support has excellent seismic performance. The arched structure can effectively disperse and transfer the horizontal and vertical loads generated by earthquakes, thereby improving the stability and seismic resistance of the overall structure. The combination of steel structure supports and structural steel plates provides a strong bearing capacity. The high strength and toughness of the steel itself, coupled with the arched design, enable the structure to withstand large external forces without being easily damaged. The arched design can reduce the use of materials while maintaining high strength, because the arched structure can more effectively utilize the bearing capacity of the material and achieve the optimal use of the material. The shape of the arched structure not only provides a solid shell, but also provides a larger column-free space inside, which improves the utilization rate of the building's internal space and is suitable for internal layouts for multiple purposes.

[0012] Furthermore, the steel structure support includes steel beams, steel purlins and steel columns. The steel beams are in a herringbone shape and their two ends are respectively installed on steel columns. The steel columns are vertically supported and installed on the ground. The steel purlins are arranged and installed on the steel beams and their two ends are respectively connected to the sides of two adjacent steel beams to form a grid structure. The structural steel plates include structural steel tiles, lap strips and mounting bolts. The structural steel tiles are folded into corrugated shapes by sheet metal. Lapping strips are respectively provided on both sides of the structural steel tiles. The two adjacent structural steel tiles are connected to each other by lap strips to form a sealed whole. The structural steel tiles are arranged and installed on the outer sides of the steel beams and steel columns by mounting bolts.

[0013] The gabled steel beam design is erected on steel columns at both ends to form a stable triangular structure. This design effectively disperses and carries the roof and external loads, improving the stability of the entire building. The steel purlins form a grid structure on the steel beams, increasing the load-bearing capacity and lateral stability of the roof. This grid layout can distribute the load more evenly and further enhance the strength of the structure. The gabled roof design not only provides strong structural support, but also increases the height and available volume of the interior space, suitable for a variety of interior space layout requirements. The structural steel tiles are sealed and spliced ​​through the corrugated design and overlapping edge strips, providing good drainage performance, reducing the risk of rainwater leakage, and improving the waterproof performance of the building. The modular corrugated steel tiles and overlapping edge strips simplify the installation process, and the use of mounting bolts makes the construction process fast and efficient, reducing construction time and cost.

[0014] Furthermore, the main structure also includes underground embedded bars, which are installed at the bottom end of the steel column. The steel column is installed and fixed on the ground through the underground embedded bars, and the underground embedded bars are buried below the ground. A pile foundation is arranged at the connection between the underground embedded bars and the steel column. The pile foundation is wrapped around the top of the underground embedded bars and cast on the ground. An expansion embedded bar tube is provided at the contact part between the underground embedded bars and the pile foundation. The upper part of the expansion embedded bar tube is wrapped in the pile foundation and the lower part is buried underground. Expansion material is poured between the expansion embedded bar tube and the underground embedded bars, and the top of the underground embedded bars is tightened and fixed to the upper surface of the pile foundation through a tensioning seat.

[0015] Underground rebar provides deeper support and anchoring effect by fixing steel columns below the ground, reducing the risk of foundation settlement and the possibility of building tilt. The application of expansion rebar tubes and the expansion materials inside them can increase the friction and bonding force of underground rebars, improve the pull-out resistance of the structure, especially when facing external forces such as pull-out force or earthquake. The pile foundation is wrapped on the top of the underground rebar. Through the combination of expansion rebar tubes and expansion materials, an effective load transfer system is formed to distribute the load of the superstructure more evenly to the foundation. The combination of underground rebar and pile foundation forms a stable structural foundation. This design can better absorb and disperse the energy transmitted to the building by seismic fluctuations, improving the seismic performance. The use of expansion materials and expansion rebar tubes provides additional protection for underground rebars, reduces the impact of soil corrosion or chemical erosion on the structure, and thus extends the service life of the building foundation. The design of the tension seat allows for more precise fixing of the top of the underground rebar, ensuring the verticality of the steel column and the precise installation of the overall structure, improving the quality and efficiency of construction.

[0016] Furthermore, the seismic buffer structure includes a tension spring and a fatigue pad. The tension spring is installed at the connection between the steel beam and the steel column and absorbs vibration from the steel beam or the steel column. The fatigue pad is installed at the contact point between the bottom end of the structural steel tile and the ground and absorbs vibration from the ground.

[0017] The tension spring is installed at the connection between the steel beam and the steel column, which can effectively absorb and buffer the dynamic stress generated by the external vibration of the steel beam and the steel column, and avoid the stress concentration caused by the rigid connection. The fatigue pad is located at the contact point between the bottom of the structural steel tile and the ground, which can effectively absorb the vibration transmitted from the ground and reduce the impact of the vibration on the steel tile and the support structure.

[0018] Furthermore, the two ends of the tension spring are respectively connected to the steel beam and the steel column through spring seats, and the tension spring is sleeved on the spring rod, and the spring rod is a telescopic rod with both ends respectively connected and fixed on the upper and lower spring seats, and the tension spring is wrapped with a protective shell, and the protective shell is made of rubber. The fatigue cushion layer includes a spring plate, a splint and a side baffle, and the upper and lower surfaces of the spring plate are clamped by the splint and respectively contact the bottom end of the structural steel tile and the ground, and side baffles are arranged on both sides of the spring plate, and the side baffles block the gap between the upper and lower splints and combine with the upper and lower splints to wrap and seal the spring plate.

[0019] The combined structure of the tension spring and the fatigue pad provides two-way buffering for the upper structure and ground vibration respectively, which greatly reduces the transmission of external vibration energy and significantly improves the shock absorption and earthquake resistance of the entire building. The tension spring protects the connection nodes between the steel beams and steel columns to avoid stress concentration and fatigue damage. The fatigue pad protects the bottom of the steel tile from ground vibration or impact damage, thereby enhancing the durability of the building foundation and upper structure. The protective design of the rubber protective shell and side baffle improves the corrosion resistance and fatigue resistance of the shock absorber, thereby extending the service life of the overall structure and shock absorption system.

[0020] Furthermore, the air duct structure includes a guide plate, a ventilation duct and a sealing gasket, the guide plate is installed on the outer surface of the main structure, the end of the guide plate is connected to the ventilation duct, the guide plate guides natural wind into the ventilation duct, the ventilation duct passes through the interior of the main structure and connects the two side surfaces of the main structure, and the connection and installation points of the guide plate and the ventilation duct are both provided and filled with sealing gaskets.

[0021] The guide plate guides natural wind into the ventilation duct and realizes efficient air circulation through the design of running through the main structure, which effectively enhances the utilization rate of natural ventilation and improves the air quality of the internal environment. The filling of the sealing gasket ensures the airtightness of the entire air duct system, avoids air leakage and the entry of pollutants, improves the reliability of system operation, makes full use of natural wind for ventilation, reduces dependence on mechanical equipment, thereby reducing energy consumption and achieving green environmental protection. The sealing gasket not only enhances the sealing of the joints, but also improves the structure's anti-vibration and anti-corrosion performance, and extends the service life of the air duct system.

[0022] Furthermore, a grid drain plate is installed on the drain plate, and the grid drain plates are arranged and installed on the outer surface of the drain plates, and the grid drain plates are arranged at intervals to form drainage grooves, and the ends of the drainage grooves are connected to the ventilation ducts, and the drainage grooves and the outer surfaces of the grid drain plates are padded with sound insulation layers, and the inner surface of the ventilation duct is affixed with a soundproof package, and expansion interfaces are provided at the connections between the two ends of the ventilation duct and the two side surfaces of the main structure, and the sealing gasket includes expansion glue and seam patching stickers, and the expansion glue is filled in the connection and installation of the drain plate and the ventilation duct, and the seam patching stickers are affixed to the edges of the connection and installation of the drain plate and the ventilation duct.

[0023] The design of the grid drain plate and drainage groove expands the natural wind capture range and reduces turbulence by optimizing the airflow path, making the overall ventilation efficiency of the air duct higher. The silent wrapping material in the ventilation duct reduces airflow resistance and noise, making the airflow more efficient and stable. The coordinated effect of the sound insulation layer, silent wrapping and expansion interface can effectively suppress the noise and resonance problems generated during airflow flow, and improve the comfort of the use environment. The sealing and protective effect of the expansion glue and the seam patch ensures the airtightness and durability of the air duct system, prevents air leakage and the invasion of external pollutants, and greatly improves the stability and service life of the system. The expansion interface buffers the connection stress, adapts to different installation conditions and environmental changes, and makes the air duct structure more flexible and reliable.

[0024] Furthermore, the ground cushion layer includes a deep foundation pit, a buffer layer, a load-bearing layer and a root retaining net. The deep foundation pit is excavated at the main structure installation location on the ground. The buffer layer and the load-bearing layer are filled in the deep foundation pit from bottom to top in sequence. The root retaining net is installed and buried on the inner surface of the deep foundation pit.

[0025] The design of the deep foundation pit and the load-bearing layer effectively disperses the load through a multi-layer distribution structure, providing extremely high foundation bearing capacity and anti-settlement performance, ensuring the long-term stable operation of the main structure. The buffer layer provides excellent shock absorption effect, which can alleviate the impact of external vibration or load fluctuation on the foundation and the main structure. It is especially suitable for places that are sensitive to vibration. The root retaining net can effectively block the invasion of plant roots and prevent foundation instability or structural damage caused by root damage. It is especially suitable for areas with dense greening or developed plant root systems. The cushion structure is reasonably designed and can adapt to a variety of geological conditions and environmental requirements.

[0026] In summary, the present invention has the following beneficial technical effects: 1. By installing the seismic support structure and the seismic buffer structure on the main structure, the seismic resistance of the overall structure is improved. The combination of the support frame, the tension rod and the keel frame can effectively disperse and transmit the seismic load, reduce the direct impact on the main structure, and the seismic buffer structure provides additional buffering capacity at the connection node to reduce the impact of vibration transmission to the main structure. This not only protects the structure itself, but also improves the safety of internal equipment and personnel. Through reasonable structural layout, the seismic support structure and the seismic buffer structure enhance the rigidity and stability of the overall structure, especially under earthquake and strong wind conditions, to ensure the safety of the plant. The design of the duct structure and the ground cushion further improves the comfort and foundation stability of the plant. The duct structure optimizes the air flow and noise reduction effect, while the ground cushion provides a good foundation support for the plant.
