Abstract
Description
Technical Field
[0001] This patent relates to industrial buildings or building complexes, specifically a steel structure factory building with multiple earthquake-resistant defenses. Background Technology
[0002] Steel structure factory buildings, a common building form in the industrial field, play an important role in engineering construction due to their high load-bearing capacity, fast construction speed, and high durability. However, steel structure factory buildings have some problems in terms of seismic performance. The design often places large, heavy process equipment in the upper space, which significantly increases the load on the factory building, making it particularly sensitive and noticeable during earthquakes. Furthermore, to accommodate the installation and maintenance of large equipment, factory buildings often require high floor heights and large spans. Such designs may cause a series of structural problems, such as insufficient shear walls and discontinuous column bracing, affecting structural stability. In addition, simultaneous construction of factory beams and the main structure may be difficult, and problems such as missing floors, large openings in floor slabs, or misaligned floors may occur, further weakening the lateral stiffness of the structure.
[0003] However, the increasing frequency of earthquakes in recent years has posed a more severe challenge to the safety of steel structure factory buildings. Earthquakes can not only damage factory equipment and halt production lines, but also cause casualties and significant losses to factories. Even if they do not collapse, steel structure factory buildings often exhibit substantial residual deformation after an earthquake, making repair work difficult and potentially requiring demolition and reconstruction. To ensure the safety of people's lives and property, reduce post-earthquake repair costs, and enable factories to quickly resume production, there is an urgent need to develop new seismic-resistant technologies for steel structure factory buildings to meet earthquake resistance requirements.

[0022] This patent aims to provide a steel structure factory building with multiple seismic defense lines to meet the seismic design goals of "no damage in minor earthquakes," "repairable in moderate earthquakes," and "no collapse in major earthquakes." This patent dissipates input energy by installing self-resetting supports with low prestress requirements between steel columns, giving the steel structure factory building recoverable functionality, reducing residual displacement after an earthquake, and enabling rapid resumption of production and normal operation. Simultaneously, in the event of a rare earthquake, the self-resetting supports and buckling-restrained supports work together to dissipate energy, controlling the residual displacement of the structure within a manageable range, thereby reducing repair costs and ensuring the safety of people and property. The multi-layered seismic defense design of this patent improves the overall seismic performance of the steel structure factory building, providing an effective solution for protection and recovery under earthquake disasters.
[0023] This patent includes a replaceable energy-consuming system, a reset system, and a bracket and transmission mechanism for mounting the energy-consuming system and the reset system, which together form an integrated unit.
[0024] The energy-consuming system includes a support rod, a self-locking clamp, and multiple energy-consuming bars, wherein the support rod and the self-locking clamp constitute a unidirectional force transmission element;
[0025] The reset system includes at least one prestressed screw;
[0026] The bracket and transmission mechanism include a first end plate, a second end plate, an intermediate plate, an inner support cylinder, and an outer support cylinder, wherein the first end plate, the second end plate, and the intermediate plate constitute the bracket for mounting the reset system and the energy dissipation system.
[0027] The inner support cylinder is fitted inside the outer support cylinder to form a movable nested structure. The two are of equal length. When the movable nested structure formed between the inner support cylinder and the outer support cylinder slides axially, the inner support cylinder and the outer support cylinder respectively push the first end plate and the second end plate to undergo relative displacement.
[0028] The pressure cap is used to hold the return spring in place and maintain the axial stability of the self-locking clamp. When under tension, the self-locking clamp withstands the tension through the interlocking of multiple clamping blocks and support rods. When under pressure, the clamping blocks and support rods disengage, and only relative sliding occurs between them without bearing pressure.
[0029] When this patent is used, external energy is introduced through a support and transmission mechanism. When the two ends of the factory building's support undergo relative displacement due to an earthquake, the energy dissipation system is subjected to tension and yields, while the reset system is subjected to tension and undergoes elastic deformation. The restoring force generated by the elastic deformation of the reset system completes the reset, thereby driving the factory building to complete the reset.
[0030] Self-resetting bracing serves as the first line of defense against earthquakes in the factory building, dissipating energy input during frequent and higher-level earthquakes and controlling residual deformation of the factory building after an earthquake. Buckling-restrained bracing serves as the second line of defense against earthquakes in the factory building, dissipating energy input during rare earthquakes.
[0031] The self-resetting support is a low-prestress support, which includes: a replaceable energy dissipation system, a reset system, and a bracket and transmission mechanism for installing the energy dissipation system and the reset system. These three components form an integrated unit, which is connected to external energy input through the bracket and transmission mechanism.
[0032] When the two ends of the self-resetting support undergo relative displacement due to earthquake action, the energy dissipation system undergoes tensile yielding deformation, while the reset system undergoes tensile elastic deformation. The reset system completes the reset through the restoring force generated by the elastic deformation of the reset system, thereby driving the plant to complete the reset.
[0033] The working principle of a self-locking clamp is as follows:
[0034] The energy dissipation stage is a load-bearing state. During the energy dissipation stage, the clamping block engages with the support rod and bears the force, thereby stretching the energy dissipation rod to dissipate energy. The reset stage is a non-load-bearing state. During the reset stage, the clamping block and the support rod disengage, and the support rod slips and does not bear the force.
[0035] This patent has the following beneficial effects:
[0036] 1. In this patent, when a frequent earthquake or a designed earthquake occurs, the low prestressed self-resetting support in the factory building can dissipate the earthquake energy and eliminate the residual deformation of the steel structure after the earthquake. While preserving the structural integrity, the factory building can be restored to its usability with almost no repair after the earthquake.
[0037] 2. In this patent, when a rare earthquake occurs, the low prestress self-resetting brace and buckling restraint brace in the factory building simultaneously dissipate the energy input to the structure. Furthermore, the low prestress self-resetting brace controls the residual deformation of the structure within a repairable range, reducing the repair cost of the factory building after the earthquake and allowing it to be put back into production and use in a short time, thus ensuring the economic benefits of the enterprise.

[0083] In this embodiment, the self-resetting support 6 is as follows: Figure 4 and Figure 5 As shown: The self-resetting support 6 includes a prestressed screw 61, a first end plate 621, a second end plate 622, an intermediate plate 623, an inner support cylinder 631, an outer support cylinder 632, a first extension plate 641, a second extension plate 642, a support rod 65, a self-locking clamp 66, and an energy-dissipating rod 67.
[0084] The first end plate 621 and the second end plate 622 are fixed at both ends of the prestressed screw 61, and the middle plate 623 is sleeved and fixed in the middle of the prestressed screw 61.
[0085] The inner support cylinder 631 is disposed between the first end plate 621 and the second end plate 622. The inner support cylinder 631 is movably sleeved on the prestressed screw 61 and passes through the intermediate plate 623, with the end face of the inner support cylinder 631 facing the first end plate 621. The length of the outer support cylinder 632 is equal to the length of the inner support cylinder 631.

[0087] One end of the support rod 65 is connected to and fixed to the first end plate 621, and the other end of the support rod 65 passes through the intermediate plate 623. The self-locking clamp 66 is clamped on the outside of the support rod 65 and fixed on the intermediate plate 623.
[0088] The two ends of the energy-consuming rod 67 are respectively connected to the fixed intermediate plate 623 and the second end plate 622.
[0089] In this embodiment, the energy dissipation rod 67 is as follows: Figure 6As shown: The energy-consuming rod 67 includes a core energy-consuming section 671 and a connecting section 672. The two ends of the energy-consuming section 671 are respectively connected to the fixed connecting section 672. The central axes of the energy-consuming section 671 and the connecting section 672 coincide with each other. The outer diameter of the connecting section 672 is not less than twice the outer diameter of the energy-consuming section 671.
[0090] In this embodiment, the self-locking clamp 66 is as follows: Figure 7 and Figure 8 As shown: The self-locking clamp 66 includes an anchor ring 661, a clamping block 662, a sealing ring 663, a pressure cap 664, and a return spring 665.
[0091] The inner wall of the anchor ring 661 is an inclined surface that gradually narrows from the mouth of the cup to the bottom of the cup. The bottom surface of the anchor ring 661 is provided with a through hole. The anchor ring 661 is sleeved on the support rod 65 through the through hole of the bottom surface and the bottom surface of the anchor ring 661 is attached to the intermediate plate 623.
[0092] There are at least three clamping blocks 662. The outer side of the clamping block 662 matches the inner side wall of the anchor ring 661, and the inner side of the clamping block 662 matches the outer side of the support rod 65. The clamping blocks 662 are sequentially embedded between the inner side wall of the anchor ring 661 and the outer side of the support rod 65 around the support rod 65. The sealing ring 663 is clamped around each clamping block 662.
[0093] The pressure cap 664 has a through hole. The pressure cap 664 is sleeved on the support rod 65 and covers the cup mouth of the anchor ring 661. The return spring 665 is sleeved on the support rod 65 and embedded between the top surface of the clamping block 662 and the pressure cap 664.
[0094] In this embodiment:
[0095] There are two prestressed screws 61, which are fixed to both sides of the first end plate 621 and the second end plate 622, respectively.
[0096] There are four support rods 65, which are evenly distributed around the inner support cylinder 631. Each support rod 65 is fitted with a self-locking clamp 66 at the point where it passes through the intermediate plate 623.
[0097] The two ends of the prestressed screw 61 are respectively fixed with nuts to the first end plate 621 and the second end plate 622;
[0098] The outer side of the energy dissipation rod 67 is provided with external threads, and the two ends of the energy dissipation rod 67 are respectively connected and fixed to the intermediate plate 623 and the second end plate 622 by nuts.
[0099] This embodiment includes a replaceable energy-consuming system, a reset system, and a bracket and transmission mechanism for mounting the energy-consuming system and the reset system, which together form an integrated unit.
[0100] The energy-consuming system includes a support rod 65, a self-locking clamp 66, and multiple energy-consuming rods 67, wherein the support rod 65 and the self-locking clamp 66 constitute a unidirectional force transmission element;
[0101] The reset system includes at least one prestressed screw 61;
[0102] The bracket and transmission mechanism include a first end plate 621, a second end plate 622, a middle plate 623, an inner support cylinder 631, and an outer support cylinder 632. The first end plate 621, the second end plate 622, and the middle plate 623 together form a bracket for mounting the reset system and the energy dissipation system.
[0103] The inner support cylinder 631 is fitted inside the outer support cylinder 632 to form a movable nested structure. The two are of equal length. When the movable nested structure formed between the inner support cylinder 631 and the outer support cylinder 632 slides axially, the inner support cylinder 631 and the outer support cylinder 632 respectively push the first end plate 621 and the second end plate 622 to undergo relative displacement.
[0104] The pressure cap 664 is used to hold the return spring 665 and maintain the axial stability of the self-locking clamp 66. When under tension, the self-locking clamp 66 bears the tension through the engagement between the multiple enclosing clamping blocks 662 and the support rod 65. When under pressure, the clamping blocks 662 and the support rod 65 disengage, and only relative sliding occurs between the clamping blocks 662 and the support rod 65 without bearing pressure.
[0105] In this embodiment, energy is introduced from the outside through a support frame and transmission mechanism. When the two ends of the plant's support shift relative to each other due to an earthquake, the energy dissipation system undergoes tensile yielding deformation, while the reset system undergoes tensile elastic deformation. The restoring force generated by the elastic deformation of the reset system completes the reset, thereby driving the plant to reset.
[0106] Self-resetting brace 6 serves as the first line of defense against earthquakes in the factory building, dissipating energy input during frequent and higher-level earthquakes and controlling residual deformation of the factory building after earthquakes. Buckling restraint brace 5 serves as the second line of defense against earthquakes in the factory building, dissipating energy input during rare earthquakes.
[0107] The self-resetting support 6 is a low prestress requirement support, including: a replaceable energy dissipation system, a reset system, and a bracket and transmission mechanism for installing the energy dissipation system and the reset system. These three components form an integrated unit, which is connected to external energy input through the bracket and transmission mechanism.
[0108] When the two ends of the self-resetting support 6 undergo relative displacement due to the earthquake, the energy dissipation system is subjected to tensile yielding deformation, while the reset system is subjected to tensile elastic deformation. The reset is completed by the restoring force generated by the elastic deformation of the reset system, which in turn drives the plant to complete the reset.
[0109] The working principle of the self-locking clamp 66 is as follows: Figure 7 and Figure 8 As shown:
[0110] The energy-consuming stage is the load-bearing state. In the energy-consuming stage, such as... Figure 7 As shown: Clamping block 662 engages with support rod 65 and bears force, thereby stretching energy-dissipating rod 67 to dissipate energy; the reset phase is a non-load-bearing state, during the reset phase, as... Figure 8 As shown: the clamping block 662 and the support rod 65 are separated, and the support rod 65 slips and does not bear any force.
