Abstract
Description
Technical Field
[0001] This utility model relates to a steel structure factory building, and more particularly to a steel structure factory building with earthquake resistance applied in the construction field. Background Technology
[0002] Steel structure factory buildings are a type of building that uses steel as the main load-bearing component. Their structural system typically consists of steel columns, beams, and trusses connected by welding, bolting, or riveting. Existing steel structure factory buildings primarily rely on rigid connections between these steel columns, beams, and trusses. When subjected to vibrations such as earthquakes, significant stress concentration occurs within this structural system. While steel itself possesses high strength, its modulus of elasticity is limited, making the steel components prone to mutual compression under strong vibrations, leading to deformation. Particular attention is warranted on the connection nodes of the steel components and the central area of the roof above the steel trusses, as these areas often experience the most significant deformation and are the most vulnerable due to the complex and concentrated stress.
[0003] A patent with publication number CN221373083U discloses a seismic-resistant steel structure for a factory building, including a fixing block. A seismic-resistant column is centrally connected to the top of the fixing block. A fireproof plate is fixed to the surface of the seismic-resistant column. A connecting plate is provided on the seismic-resistant column, and a connecting bolt is fixed to the connecting plate. A limit bolt is connected to one side wall of the fixing block, and a limit bolt is installed at the end of the limit bolt. A crossbeam is fixed to the top of the seismic-resistant column, and a reinforcing plate is provided at the top of the crossbeam. The beneficial effects are: This invention, by inserting the seismic-resistant column into the fixing block, inserting the limit bolt through the seismic-resistant column, and then tightening the limit bolt to fix it, and by tightening the connecting bolt to firmly fix the connecting plate on the seismic-resistant column to the fixing block, can prevent the seismic-resistant column from detaching from the fixing block during an earthquake, thus preventing the seismic-resistant factory building from collapsing and endangering people's safety, and improving the safety performance of the factory building's steel structure.
[0004] The aforementioned patents improve the stability of the anti-vibration column connections, but they do not solve the problem of stress concentration during vibration caused by rigid connections between components in existing steel structures. Utility Model Content
[0005] The technical problem to be solved by this utility model in view of the above-mentioned prior art is that the rigidly connected steel components of existing steel structure workshops are prone to stress concentration during vibration.
[0006] To address the aforementioned issues, this utility model provides a steel structure factory building with earthquake resistance, comprising a factory building body; the factory building body includes a split roof, the split roof including a ridge plate and a pair of mirror-arranged side roof plates, the ridge plate being located above the pair of side roof plates, and steel columns being fixedly connected to the lower ends of the side roof plates, with concrete foundations connected to the lower ends of the steel columns; the steel columns and the side roof plates are flexibly connected to the ridge plate via the same flexible steel frame;
[0007] The flexible steel frame includes a lower buffer seat between a pair of side top plates and an upper buffer seat between the ridge plate and the side top plates. A pair of first connecting rods are hinged to both sides of the lower buffer seat, and the lower ends of the pair of first connecting rods are respectively hinged to the steel columns located on both sides. A pair of second connecting rods are hinged to both sides of the upper buffer seat, and the lower ends of the second connecting rods are respectively hinged to the inner walls of the side top plates located on both sides. A sliding rod that is fixedly connected to the lower end of the ridge plate passes through the lower buffer seat and the upper buffer seat. A second spring is sleeved on the upper part of the sliding rod, and the upper end of the second spring abuts against the ridge plate and its lower end abuts against the upper buffer seat. A third spring is sleeved on the middle part of the sliding rod, and the upper end of the third spring abuts against the upper buffer seat and its lower end abuts against the lower buffer seat.
[0008] In the aforementioned steel structure factory buildings with earthquake-resistant properties, the use of a split roof and flexible steel frame reduces the stress concentration caused by the mutual compression between steel structure components during vibration.
[0009] As a further improvement of this application, the lower buffer seat and the upper buffer seat have the same structure. The lower buffer seat includes a strip seat, a pair of sliding blocks are slidably connected to both sides of the strip seat, a pair of first springs are abutted on both sides of the sliding blocks, the upper end of the first connecting rod is hinged to the sliding block of the lower buffer seat, and the upper end of the second connecting rod is hinged to the sliding block of the upper buffer seat.
[0010] As a further improvement of this application, the lower end of the steel column is connected to the concrete foundation through a foundation damping mechanism. The foundation damping mechanism includes a fixed cylinder that is fixedly connected to the concrete foundation. A sliding platform is slidably connected inside the fixed cylinder. The lower end of the steel column is fixedly connected to the upper end of the sliding platform. Multiple damping spring rods that are circumferentially distributed are hinged to the outer wall of the sliding platform. The outer ends of the damping spring rods are hinged to the inner wall of the fixed cylinder.
[0011] As a further improvement of this application, the strip seat is a block structure with transverse sliding grooves on both end faces that cooperate with the sliding block, and a vertical sliding groove for the sliding rod to pass through is provided in the middle of the lower buffer seat.
[0012] As a further improvement of this application, a guide rod that passes through the sliding block is fixedly connected to the transverse slide, a pair of first springs are sleeved on the two sides of the guide rod located on the sliding block, the vertical slide groove is a through hole with a square cross-section, the sliding rod is a prism rod with a square cross-section, and a limit plate is fixedly connected to the lower end of the sliding rod.
[0013] As a further improvement of this application, the fixed cylinder is fixedly connected to the concrete foundation by bolts. The sliding table has an inverted multi-stage frustum structure, and the fixed cylinder is a cylindrical structure with an open top. The diameter of the upper surface of the sliding table is larger than the inner diameter of the upper opening of the fixed cylinder. A limiting ring located below the shock-absorbing spring rod is fixedly connected inside the fixed cylinder. The limiting ring limits the maximum sliding distance of the sliding table.
[0014] As a further improvement of this application, a sliding ring is fixedly sleeved at the lower end of the sliding table, and multiple balls that abut against the fixed cylinder are nested in the lower part of the sliding ring.
[0015] In summary, this utility model, through a split roof consisting of a pair of side top plates and a ridge plate, and a flexible steel frame, allows the flexible steel frame to deform and push the ridge plate up and down during vibrations, thereby absorbing the vibrations. Simultaneously, the deformation of the flexible steel frame and the movement of the ridge plate reduce the internal stress of the overall steel frame. Compared to traditional rigidly connected steel frame structures, this design offers better seismic resistance and reduces deformation of steel frame components caused by internal stress during vibrations, thus improving the stability of the factory steel frame structure during vibrations and extending its service life.

[0024] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.
[0025] Implementation method 1:
[0026] Figure 1-4 The diagram illustrates a steel structure factory building with earthquake resistance, comprising a factory building body; the factory building body includes a split roof, the split roof includes a ridge plate 4 and a pair of mirror-arranged side roof plates 3, the ridge plate 4 is located above the pair of side roof plates 3, the lower end of the side roof plates 3 is fixedly connected to a steel column 2, the lower end of the steel column 2 is connected to a concrete foundation 1; the steel column 2 and the side roof plates 3 are flexibly connected to the ridge plate 4 by the same flexible steel frame 5;
[0027] Please see Figure 2 and Figure 3 The flexible steel frame 5 includes a lower buffer seat 6 disposed between a pair of side top plates 3 and an upper buffer seat 12 disposed between the ridge plate 4 and the side top plates 3. A pair of first connecting rods 11 are hinged to both sides of the lower buffer seat 6, and the lower ends of the pair of first connecting rods 11 are respectively hinged to the steel columns 2 located on both sides. A pair of second connecting rods 13 are hinged to both sides of the upper buffer seat 12, and the lower ends of the second connecting rods 13 are respectively hinged to the inner walls of the side top plates 3 located on both sides. A sliding rod 14, which is fixedly connected to the lower end of the ridge plate 4, passes through the lower buffer seat 6 and the upper buffer seat 12. A second spring 15 is sleeved on the upper part of the sliding rod 14, and the upper end of the second spring 15 abuts against the ridge plate 4 and its lower end abuts against the upper buffer seat 12. A third spring 16 is sleeved in the middle of the sliding rod 14, and the upper end of the third spring 16 abuts against the upper buffer seat 12 and its lower end abuts against the lower buffer seat 6.
[0028] Specifically, when the factory building vibrates, the ground vibration is transmitted to the steel column 2 through the concrete foundation 1. The steel column 2 then transmits the vibration to the side roof plate 3. The steel column 2 pushes the lower buffer seat 6 to move up and down through the first connecting rod 11. The side roof plate 3 pushes the upper buffer seat 12 to move up and down through the second connecting rod 13. The lower buffer seat 6 and the upper buffer seat 12 drive the ridge plate 4 to move up and down through the sliding rod 14, the second spring 15, and the third spring 16, thereby absorbing the vibration, reducing the internal stress of the steel structure and roof of the factory building, and improving the seismic resistance.
[0029] Compared to traditional steel structure factory buildings, this utility model features a split roof consisting of a pair of side top plates 3 and a ridge plate 4, along with a flexible steel frame 5. When vibration occurs, the flexible steel frame 5 deforms and pushes the ridge plate 4 up and down, thus absorbing the vibration. At the same time, the deformation of the flexible steel frame 5 reduces the internal stress of the overall steel frame. Compared to traditional rigidly connected steel frame structures, this design offers better seismic resistance and reduces the deformation of steel frame components caused by internal stress during vibration, thereby improving the stability of the factory building's steel frame structure during vibration and extending its service life.
[0030] Please see Figure 3 The lower buffer seat 6 and the upper buffer seat 12 have the same structure. The lower buffer seat 6 includes a strip seat 7. A pair of sliding blocks 8 are slidably connected on both sides of the strip seat 7. A pair of first springs 10 are abutted on both sides of the sliding blocks 8. The upper end of the first connecting rod 11 is hinged to the sliding block 8 of the lower buffer seat 6, and the upper end of the second connecting rod 13 is hinged to the sliding block 8 of the upper buffer seat 12.
[0031] Specifically, when the steel column 2 and the side top plate 3 experience lateral vibration, the steel column 2 pushes the sliding block 8 in the lower buffer seat 6 to slide laterally through the first connecting rod 11, compressing the first spring 10 in the lower buffer seat 6. At the same time, the side top plate 3 pushes the sliding block 8 in the upper buffer seat 12 to move laterally through the second connecting rod 13, compressing the first spring 10 in the upper buffer seat 12, thereby absorbing and reducing lateral vibration.
[0032] Please see Figure 4 The strip seat 7 has a block structure and has transverse grooves 701 on both end faces that cooperate with the sliding block 8. The lower buffer seat 6 has a vertical groove 702 in the middle for the sliding rod 14 to pass through.
[0033] Specifically, when vibration occurs, the sliding block 8 slides laterally in the transverse groove 701, and the sliding rod 14 slides vertically in the vertical groove 702, thereby absorbing vibration in both the horizontal and vertical directions.
[0034] Please see Figure 4A guide rod 9 that passes through the sliding block 8 is fixedly connected inside the transverse slide groove 701. A pair of first springs 10 are sleeved on the guide rod 9 on both sides of the sliding block 8. The vertical slide groove 702 is a through hole with a square cross-section. The sliding rod 14 is a prism rod with a square cross-section. The lower end of the sliding rod 14 is fixedly connected to a limit plate 1401.
[0035] Specifically, the stability of the sliding block 8 and the sliding rod 14 is improved by the guide rod 9 and the limiting plate 1401.
[0036] The second implementation method:
[0037] Figure 5 and Figure 6 This invention illustrates a steel structure factory building with earthquake resistance. Based on the first embodiment, the lower end of the steel column 2 is connected to the concrete foundation 1 through a foundation damping mechanism 17. The foundation damping mechanism 17 includes a fixed cylinder 18 fixedly connected to the concrete foundation 1. A sliding platform 19 is slidably connected inside the fixed cylinder 18. The lower end of the steel column 2 is fixedly connected to the upper end of the sliding platform 19. A plurality of damping spring rods 20 are hinged to the outer wall of the sliding platform 19 and are distributed equidistantly in a circle. The outer ends of the damping spring rods 20 are hinged to the inner wall of the fixed cylinder 18.
[0038] Specifically, when the concrete foundation 1 vibrates, the sliding table 19 slides within the fixed cylinder 18. Simultaneously, the sliding table 19 compresses the damping spring rod 20, which absorbs the vibration, thereby improving the stability of the steel column 2. This replaces the traditional rigid connection between the steel column 2 and the concrete foundation 1, reducing the degree of compression and breakage of the concrete foundation 1 by the steel column 2 during vibration. At the same time, the limiting ring 23 protects the damping spring rod 20, preventing it from being excessively compressed.
[0039] Please see Figure 6 The fixed cylinder 18 is fixedly connected to the concrete foundation 1 by bolts. The sliding table 19 has an inverted multi-stage frustum structure. The fixed cylinder 18 is a cylindrical structure with an open top. The diameter of the upper end face of the sliding table 19 is larger than the inner diameter of the upper end opening of the fixed cylinder 18. A limiting ring 23 located below the shock-absorbing spring rod 20 is fixedly connected inside the fixed cylinder 18. The limiting ring 23 limits the maximum sliding distance of the sliding table 19.
[0040] Specifically, the sliding table 19 can only slide horizontally within the fixed cylinder 18 after being confined therein. The sliding table 19 can slide in multiple arbitrary horizontal directions due to the multiple circumferentially distributed damping spring rods 20 hinged to it, which have a good absorption and damping effect on the vibration transmitted by the concrete foundation 1.
[0041] Please see Figure 5The shock-absorbing spring rod 20 includes a piston cylinder 2001, a piston rod 2002 slidably connected to the piston cylinder 2001, and a fourth spring 2003 nested in the piston cylinder 2001 and abutting against the end of the piston rod 2002. The end of the piston cylinder 2001 away from the piston rod 2002 is hinged to the inner wall of the fixed cylinder 18 through a hinge seat, and the end of the piston rod 2002 away from the piston cylinder 2001 is hinged to the sliding table 19 through a hinge seat.
[0042] Specifically, when the sliding table 19 slides horizontally, the fourth spring 2003 is compressed, thereby absorbing the vibration.
[0043] Please see Figure 5 and Figure 6 A sliding ring 21 is fixedly sleeved at the lower end of the sliding table 19, and multiple balls 22 that abut against the fixed cylinder 18 are nested in the lower part of the sliding ring 21.
[0044] Specifically, the sliding table 19 contacts the fixed cylinder 18 through the ball bearings 22 of the sliding ring 21, reducing the friction between the sliding table 19 and the fixed cylinder 18 and extending the service life of the base damping mechanism 17.
[0045] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
