Description

Technical Field

[0001] The invention relates to the technical field of building civil engineering, and in particular to an assembled steel structure sliding node with a limiting device. Background Art

[0002] With the promotion and use of large-scale exhibition buildings, steel structure roofs are increasingly used in large-span and ultra-long structures. Ultra-long roofs need to be equipped with structural separation joints to reduce temperature stress and avoid irregularities in the structural system.

[0003] Slidable connection nodes need to be set at the locations of structural joints. Slidable connection nodes can adapt to a certain range of deformations and effectively reduce the internal forces of the structure; the force transmission is simple and the interference is low, which can reduce the adverse effects of the erection body on the supporting body; secondly, the sliding connection of the steel structure has good seismic performance and can better protect the structure from natural disasters such as earthquakes; in addition, the sliding connection of the steel structure can also provide better economy and sustainability, which can reduce the cost of maintenance and replacement in long-term use. The traditional approach to setting up slidable connection nodes is to use a combination of oblong holes and high-strength bolts, but this method can only allow the steel structure to slide in one direction in the direction of the oblong holes. In actual applications, the bearing capacity of the high-strength bolts will drop significantly after repeated sliding in the oblong holes, posing a safety risk. Summary of the invention

[0004] In view of this, the present invention provides a steel structure sliding node with a limiting device, aiming to solve the limitations of traditional one-way sliding nodes and the potential safety hazards caused by the reduction in the bearing capacity of high-strength bolts.

[0005] The present invention provides an assembled steel structure sliding node with a limiting device, comprising a supporting body, an erecting body, a sliding panel and a limiting baffle, wherein a corbel is fixedly connected to the side of the supporting body, a sliding panel is provided on the top surface of the corbel, and a limiting baffle is provided on the periphery of the sliding panel; a sliding shoe is provided at one end of the erecting body, and the sliding shoe is slidably placed on the sliding panel of the corbel.

[0006] By setting up a supporting body and firmly connecting the side of the support leg, a solid foundation is laid for the entire node system. As a key force transmission and transfer component, the support leg can reliably bear various loads from the erection body and effectively disperse and transmit them to the supporting body, thereby ensuring the rationality and stability of the structural force; a sliding shoe is set at one end of the erection body, and the sliding shoe is slid and placed on the sliding panel of the support leg, thereby forming a stable mechanical transmission path. This layout can evenly disperse the stress and avoid stress concentration, effectively breaking through the limitations of traditional unidirectional sliding nodes that can only achieve unidirectional force transmission and uneven force, and adapting to the complex and changeable force conditions of large-span and ultra-long structures; the steel beam in the erection body is the core load-bearing component, which is closely combined with the sliding shoe, and the steel beam can bear the main load by virtue of its own good mechanical properties. The setting of the sliding shoe can give the steel beam the ability to flexibly displace in the plane, so that the erection body can adapt to the temperature changes. The sliding panel is arranged on the corbel, which creates a smooth contact interface for the sliding of the erection body, effectively reduces the sliding friction, reduces the friction loss and the additional internal force caused by friction, ensures the smooth sliding process of the erection body, and improves the durability and reliability of the sliding node; the limit baffle is arranged on the periphery of the sliding panel, which accurately defines the sliding boundary of the erection body. When encountering extreme working conditions such as strong earthquakes and strong winds, it can effectively prevent the erection body from being separated from the supporting body due to excessive displacement, and avoid collision with the supporting body or surrounding components, avoiding the risk of connection failure caused by the decrease in bearing capacity after repeated sliding of high-strength bolts, and comprehensively ensuring the integrity and stability of the sliding node of the steel structure under complex working conditions, and effectively solving the problems existing in the application of traditional one-way sliding nodes and high-strength bolts.

[0007] Optionally, it further comprises an embedded part, which is arranged on the corbel and has a sliding panel welded to the embedded part.

[0008] By adding embedded parts to the corbel and welding the sliding panel to the embedded parts, on the one hand, the embedded parts are like anchor bolts rooted in the corbel, which greatly enhances the reliability of the connection between the sliding panel and the corbel, so that it can still be firmly attached when facing complex stress conditions such as frequent sliding and impact of the erection body, and effectively avoid problems such as structural displacement deviation caused by loose connection; on the other hand, the welding method allows the sliding panel and the embedded parts to be tightly integrated into one, which can efficiently and accurately transmit various loads, ensuring the uniform force of the sliding nodes of the entire steel structure, and providing a key alternative structure to solve the safety risks caused by the easy reduction of the bearing capacity of the high-strength bolts at the connection parts of traditional one-way sliding nodes.

[0009] Optionally, the sliding panel includes a stainless steel plate and a polytetrafluoroethylene plate, the polytetrafluoroethylene plate is fixed to the stainless steel plate, and the sliding shoe slides on the polytetrafluoroethylene plate.

[0010] By adopting a sliding panel composed of a stainless steel plate and a polytetrafluoroethylene plate, and fixing the polytetrafluoroethylene plate on the stainless steel plate, on the one hand, the stainless steel plate, as a base layer, has good strength and durability, and can provide a stable support frame for the entire sliding panel, ensuring that in the long-term use process, in the face of various complex loads and environmental erosion, the panel structure remains intact, laying a solid foundation for the stable sliding of the erection body, and effectively avoiding deformation, damage and other problems caused by insufficient strength of the panel itself; on the other hand, the polytetrafluoroethylene plate, due to its extremely low friction coefficient characteristics, greatly reduces the friction when the sliding shoe slides on its surface. In daily operation, no matter it is a tiny displacement of the erection body caused by temperature changes or a larger sliding caused by extreme working conditions such as earthquakes, the sliding shoes can move smoothly and unimpeded on the polytetrafluoroethylene plate, which not only reduces the energy loss in the sliding process and reduces the additional impact on the overall structure of the node, but also reduces the wear between components, and extends the service life of related parts such as sliding panels and sliding shoes. At the same time, it also enables the erection body to adapt to structural deformation requirements more sensitively and efficiently, solving the problem of traditional unidirectional sliding nodes limiting their ability to adapt to structural deformation due to large friction resistance.

[0011] Optionally, the erection body includes a steel beam, and the sliding shoe is welded to the bottom of the steel beam.

[0012] By welding the sliding shoe to the bottom of the steel beam, the stable connection method of welding makes the sliding shoe and the steel beam tightly integrated. During the stress process of the structure, there will be no loosening, displacement and other adverse conditions between the two, ensuring the reliable transmission of the stress generated between the steel structures. Whether it is the vertical bearing weight of the erection body or the friction and impact force caused by deformation in the horizontal direction, it can effectively avoid the risk of structural failure caused by loose connection, thereby overcoming the problem of poor reliability of the traditional one-way sliding node connection.

[0013] Optionally, the steel beam is an H-shaped steel beam, and the H-shaped steel beam includes a web and a flange, and vertical stiffening ribs are arranged at positions on both sides of the web corresponding to the sliding shoes.

[0014] By setting vertical stiffening ribs at the positions corresponding to the sliding shoes on both sides of the web, on the one hand, the steel beam adopts H-shaped steel beam because of its significant structural advantages of web and flange. The web mainly bears vertical shear force and has high shear resistance, ensuring the vertical stability of the structure under complex stress conditions; the flange focuses on bending resistance. When the erection body is subjected to eccentric load or bending moment is generated due to deformation, the flange can effectively resist bending deformation, so that the entire steel beam maintains good mechanical properties, providing solid and reliable support for the erection body, solving the problem of insufficient strength and poor adaptability of the traditional one-way sliding node support structure, so that the steel structure sliding node can better cope with the complex stress requirements in large-span and ultra-long structures. The vertical stiffening ribs are like adding a solid "shield" to both sides of the web. When the structure is under load, especially when the erection body has a large displacement due to temperature changes, vibrations and other factors, causing the sliding shoes to produce uneven lateral forces on the web, the vertical stiffening ribs can effectively share these lateral forces, avoid buckling and deformation of the web due to excessive local force, ensure the stability of the overall structure of the steel beam, and overcome the problem of local instability of the traditional one-way sliding node support structure. In addition, multiple vertical stiffening ribs work together to enhance the stiffness of the web area, so that the steel beam can play a more efficient and stable role when transmitting vertical loads and responding to horizontal deformations, ensuring a smooth force transmission path, allowing the entire steel structure sliding node to maintain reliable performance under complex force environments, and laying a solid foundation for solving the safety risks caused by insufficient structural stiffness, easy deformation, and reduced bearing capacity of high-strength bolts in traditional one-way sliding nodes.

[0015] Optionally, there are at least two vertical stiffening ribs, the thickness of the vertical stiffening ribs is the same as the thickness of the flange, and the thickness of the sliding shoe is the same as the thickness of the web.

[0016] By setting at least two vertical stiffening ribs and making their thickness equal to the flange thickness, the stability of the web when bearing vertical loads can be greatly enhanced, local buckling and deformation of the web due to excessive force can be avoided, and the rigidity of the overall structure of the steel beam can be ensured, so that the steel beam can always maintain a reliable bearing capacity when bearing the main load of the erection body and coping with various working conditions; at the same time, the thickness of the sliding shoe is made the same as the thickness of the web, which ensures the integrity and strength matching of the connection between the sliding shoe and the steel beam. During the frequent sliding of the sliding shoe, the horizontal friction force and possible impact loads, no stress concentration or connection weak points will be generated due to the thickness difference, ensuring that the displacement function of the erection body is stable and reliable, and then effectively cooperating with the entire node system to solve the limitations of traditional one-way sliding nodes and the safety hazards caused by the reduction in the bearing capacity of high-strength bolts, providing a solid guarantee for the safe application of steel structures in complex stress environments.

[0017] Optionally, the limit baffle includes an X-direction limit steel plate and a Y-direction limit steel plate, the X-direction limit steel plate limits the sliding distance of the sliding shoe on the sliding panel along the X direction, and the Y-direction limit steel plate limits the sliding distance of the sliding shoe on the sliding panel along the Y direction.

[0018] By setting the X-direction limit steel plate, the maximum displacement of the sliding shoe in the X-direction can be accurately controlled. When encountering extreme working conditions such as strong wind blowing horizontally and earthquake shaking horizontally, it can effectively prevent the erection body from sliding excessively in this direction, avoid collision and damage with the supporting body or surrounding components, and ensure the stability of the entire steel structure system when subjected to horizontal lateral force; by setting the Y-direction limit steel plate, the sliding boundary of the sliding shoe in the Y-direction is strictly limited. When facing situations such as longitudinal expansion and contraction caused by temperature changes and longitudinal displacement caused by vertical vibrations, it is ensured that the erection body will not exceed the safe displacement range, maintain the integrity of the structure, and then effectively cooperate with the entire node system to solve the safety hazards caused by the traditional unidirectional sliding node that can only transmit force in one direction, uneven force, and the reduction of the bearing capacity of high-strength bolts, laying a solid foundation for the reliable operation of steel structures in complex and changing environments.

[0019] Optionally, X-direction limiting steel plate stiffening ribs are welded on the X-direction limiting steel plate, and Y-direction limiting steel plate stiffening ribs are welded on the Y-direction limiting steel plate.

[0020] By welding X-direction limit steel plate stiffening ribs on the X-direction limit steel plate, when the steel structure encounters extreme horizontal force impacts such as strong winds and earthquakes, the stiffening ribs can significantly enhance the bending resistance of the X-direction limit steel plate, so that it is not easy to bend and deform itself in the process of blocking the excessive displacement of the sliding shoe in the X direction, and reliably maintain the restriction on the displacement boundary of the sliding shoe to ensure the lateral stability of the structure; by welding Y-direction limit steel plate stiffening ribs on the Y-direction limit steel plate, when facing the longitudinal force caused by temperature changes, vertical vibrations, etc., the stiffening ribs provide strong support for the Y-direction limit steel plate, effectively improve its deformation resistance, accurately limit the sliding range of the sliding shoe in the Y direction, ensure the safety and controllability of the longitudinal displacement of the erection body, and then coordinate the entire node system to effectively solve the safety hazards caused by uneven force on traditional unidirectional sliding nodes and reduced bearing capacity of high-strength bolts, and provide solid guarantees for the stable operation of steel structures under complex working conditions.

[0021] Optionally, the dimensions of the X-direction limiting steel plate stiffening ribs are 20mm thick × 80mm wide × 100mm long, and the X-direction limiting steel plate stiffening ribs are arranged at intervals of 150mm along the X direction. The dimensions of the Y-direction limiting steel plate stiffening ribs are 20mm thick × 55mm wide × 100mm long, and the Y-direction limiting steel plate stiffening ribs are arranged at intervals of 150mm along the Y direction. The dimensions of the X-direction limiting steel plate are 20mm thick × 100mm wide × 600mm long, and the dimensions of the Y-direction limiting steel plate are 20mm thick × 100mm wide × 800mm long.

[0022] By setting the X-direction limit steel plate stiffening ribs to a specific size and distributing them at intervals of 150 mm, when the steel structure encounters extreme horizontal force impacts such as strong winds and earthquakes, on the one hand, the size and spacing can ensure that the stiffening ribs work together to exert the maximum bending resistance and support the X-direction limit steel plate with sufficient strength, so that it has a stronger ability to resist bending deformation in the process of blocking excessive displacement of the sliding shoe in the X direction, and reliably maintains precise control of the displacement boundary of the sliding shoe; on the other hand, reasonable spacing arrangement avoids excessive concentration of materials, optimizes the balance between cost and structural performance, and ensures the lateral stability of the structure. By setting the Y-direction limiting steel plate stiffening ribs to the corresponding specific size and distributing them at the same interval of 150mm, when facing the longitudinal forces caused by temperature changes, vertical vibrations, etc., the stiffening ribs can provide just the right support for the Y-direction limiting steel plate, effectively improve its anti-deformation ability, accurately limit the sliding range of the sliding shoe in the Y direction, ensure the safety and controllability of the longitudinal displacement of the erection body, and take into account the economy, thereby effectively coordinating the entire node system, effectively solving the safety hazards caused by the uneven force of traditional unidirectional sliding nodes and the reduced bearing capacity of high-strength bolts, and providing a solid guarantee for the stable operation of steel structures under complex working conditions.

[0023] Optionally, the supporting body is a concrete column or a steel column.

[0024] By allowing concrete columns to be used as the main support, in some building scenarios with high requirements for fire prevention and durability and relatively stable structural forces, concrete columns, with their good fire resistance and corrosion resistance, can provide a solid foundation support for the entire steel structure sliding node, ensuring the reliability of the sliding node during long-term use and reducing the frequency of maintenance; at the same time, the relatively low cost of concrete columns can optimize the overall project cost. In the case of strict requirements on the deadweight and strength of the structure, and high demands on the construction progress, steel columns are selected as the main support. Their high strength and light weight enable the steel structure sliding node to more efficiently carry complex and variable loads, adapt to the needs of building structures such as large spans and ultra-high spaces, speed up the construction process, and flexibly match different building conditions, solve the safety hazards caused by the force limitations of traditional one-way sliding nodes and the reduction in the bearing capacity of high-strength bolts, and broaden the road for the application of steel structures in diversified construction projects.

[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0032] In the field of building civil engineering technology, with the increase of large exhibition buildings, steel structure roofs are widely used in large-span and super-long structures. The super-long roofs need to be provided with structural separation seams to reduce temperature stress, and slidable connection nodes need to be provided at the structural separation seams to reduce the adverse effects of the erection body 3 of the super-long roof on the supporting body 1. For example, when encountering an earthquake, good seismic resistance can protect the steel structure and reduce the cost of long-term maintenance and replacement. However, the slidable connection nodes set in the past often adopt the combination of oblong holes and high-strength bolts, that is, the steel structure is allowed to slide unidirectionally in the direction of the oblong holes. However, in actual use, after the high-strength bolts slide repeatedly in the oblong holes, the bearing capacity will drop significantly, posing certain safety hazards.

[0033] In view of the limitations of traditional one-way sliding nodes and the potential safety hazards caused by the reduction in the bearing capacity of high-strength bolts, this embodiment proposes a steel structure sliding node with a limiting device.

[0034] like Figures 1 to 3 As shown, a steel structure sliding node with a limiting device provided in this embodiment mainly comprises: a supporting body 1, a mounting body 3, a sliding panel 6 and a limiting baffle 7. A corbel 2 is fixedly connected to the side of the supporting body 1, a sliding panel 6 is provided on the top surface of the corbel 2, and a limiting baffle 7 is provided on the periphery of the sliding panel 6; a sliding shoe 5 is provided at one end of the mounting body 3, and the sliding shoe 5 is slidably placed on the sliding panel 6 of the corbel 2.

[0035] In this embodiment, it can be understood by those skilled in the art that, in terms of the supporting body 1, it is clearly defined that the side thereof is fixedly connected to the corbel 2, which constructs an initial solid foundation for the entire node system and provides an indispensable fulcrum for the subsequent construction of the erection body 3, so that the node can better bear loads from all directions and adapt to the complex and changeable stress conditions of the building structure in actual use; in terms of the erection body 3, one end of the erection body 3 is placed on the corbel 2, and the other end is placed on another supporting body 1, thereby optimizing the force transmission path of the steel structure, so that the internal stress of the steel structure can be effectively dispersed and transmitted, effectively responding to the force requirements of large-span and ultra-long steel structures, and solving the limitations of traditional unidirectional sliding nodes that can only transmit force in one direction and uneven force; at the same time, the steel beam 4, as the main load-bearing component, can be provided with a sliding shoe 5 at the bottom of the steel beam 4, giving the erection body 3 the ability to flexibly displace in the plane, so that the erection body 3 can dynamically adapt to the changes in temperature, vibration and impact. The structural deformation caused by external factors such as impact can be avoided, and excessive stress can be accumulated inside the steel structure due to rigid connection, thereby effectively overcoming the disadvantages of uneven force on traditional one-way sliding nodes and easy local stress concentration; in terms of the sliding panel 6, it can be set on the top surface of the corbel 2, creating a smooth plane for the sliding of the erection body 3, and ensuring the smoothness of the erection body 3 during the movement, reducing friction loss, improving the overall durability and reliability of the sliding node, and ensuring the stable performance of the steel structure in long-term use; in terms of the limit baffle 7, it is arranged on the periphery of the sliding panel 6, just like defining a "safe area" for the sliding of the erection body 3, accurately and effectively controlling the displacement boundary of the erection body 3, and effectively preventing the erection body 3 from losing control due to excessive displacement when encountering extreme working conditions, such as strong winds and earthquakes. It also avoids the situation where it collides violently with the supporting body 1 and causes structural damage, effectively improving the overall stability and safety of the steel structure.

[0036] In this embodiment, the unique sliding shoe 5 design of the erection body 3, combined with the smooth support of the sliding panel 6 and the precise control of the limit baffle 7, not only optimizes the internal stress distribution of the steel structure and allows the stress to be evenly dispersed and transmitted, but also fundamentally solves the problem that traditional one-way sliding nodes can only transmit force in one direction and are prone to uneven force. At the same time, it avoids a series of safety risks caused by the reduction of bearing capacity due to repeated sliding of high-strength bolts, and provides an innovative and reliable node solution for modern building steel structures, especially for applications in large-span and ultra-long structures.

[0037] It should be noted that this embodiment only limits the basic structure of the steel structure sliding node with a limiting device, and does not limit the connection between the sliding panel 6 and the corbel 2, as well as the specific structural details of the sliding panel 6, the connection form between the steel beam 4 and the sliding shoe 5, the type of the steel beam 4, the structural details of the steel beam 4, the reinforcement of the steel beam 4 and the sliding shoe 5, the composition details of the limit baffle 7, the reinforcement of the limit baffle 7, the setting of the limit baffle 7 and the condition of the supporting body 1.

[0038] The connection between the sliding panel 6 and the corbel 2 of this embodiment is described in detail below.

[0039] like Figures 1 to 3 In some embodiments shown, an embedded part 8 is further included. The embedded part 8 is arranged on the corbel 2 , and a sliding panel 6 is welded to the embedded part 8 .

[0040] Specifically, in this embodiment, it can be understood by those skilled in the art that, by adding the embedded part 8 to the corbel 2 and welding the sliding panel 6 to the embedded part 8, on the one hand, the embedded part 8 is implanted into the corbel 2 like a solid "foundation", which greatly enhances the connection stability between the sliding panel 6 and the corbel 2. In actual working conditions, whether it is the structural micro-deformation caused by daily temperature changes or the strong vibration caused by extreme natural disasters such as earthquakes and strong winds, the embedded part 8 can ensure that the sliding panel 6 is always firmly attached to the corbel 2 without loosening or displacement, thereby providing reliable support for the stable sliding of the erection body 3, effectively avoiding the risk of uncontrolled structural deformation caused by unreliable connection of the sliding panel 6, and solving the problem of easy loosening of the connection part of the traditional one-way sliding node; on the other hand, welding, as a high-strength connection method, closely connects the sliding panel 6 and the embedded part 8, so that the two form an organic whole. When the erection body 3 slides on the sliding panel 6, the various loads generated, including vertical pressure, horizontal friction, etc., can be efficiently and evenly transmitted to the corbel 2 through the welding parts, and then dispersed to the supporting body 1, ensuring the force balance of the entire steel structure sliding node, avoiding structural damage due to excessive local force, overcoming the hidden danger of connection failure caused by the decrease in the bearing capacity of high-strength bolts, and effectively improving the ability of the node to operate reliably for a long time under complex and changeable working conditions.

[0041] In addition, in other embodiments, Figure 1 and Figure 2As shown, the embedded part 8 can be fastened with a chemical anchor bolt 18. When the embedded part 8 is set as a chemical anchor bolt 18, compared with the traditional embedded part 8, this anchoring method does not need to destroy the original structure of the corbel 2 on a large scale to implant the embedded part 8. It only needs to drill a hole in the embedded part 8, inject a chemical agent, and insert the anchor bolt to complete the installation. This simplifies the construction process and reduces the risk of damage to the original structure. Moreover, the chemical anchor bolt 18 can adapt to the complex stress environment inside the corbel 2 after solidification. Even if there are fine cracks or unevenness on the surface of the corbel 2, the chemical anchor bolt 18 can still ensure the reliable fixation of the sliding panel 6 through chemical bonding, further improving the adaptability of the node to complex working conditions. In other words, whether the embedded part 8 is fastened by setting it as a chemical anchor bolt 18 or other common fastening methods, such as expansion bolt fastening or welding fastening, it belongs to the protection scope of this embodiment.

[0042] The specific structural details of the sliding panel 6 of this embodiment are described in detail below.

[0043] like Figures 1 to 3 In some embodiments shown, the sliding panel 6 includes a stainless steel plate 9 and a polytetrafluoroethylene plate 10 . The polytetrafluoroethylene plate 10 is fixed on the stainless steel plate 9 , and the sliding shoe 5 slides on the polytetrafluoroethylene plate 10 .

[0044] Specifically, in the present embodiment, it can be understood by those skilled in the art that, on the one hand, the stainless steel plate 9, as a basic bearing layer, has high strength and good durability, and can provide a stable support frame for the entire sliding panel 6, so that in the long-term use process, when facing various complex external forces such as wind load, snow load and structural deadweight, it can still maintain the integrity of its own structure, and will not easily deform, break and other problems, thereby laying a solid foundation for the smooth sliding of the erection body 3, and effectively solving the problem of poor reliability of traditional one-way sliding nodes caused by insufficient strength of the sliding panel 6; on the other hand, the polytetrafluoroethylene plate 10 plays a key role with its extremely low friction coefficient characteristics. When the sliding shoe 5 slides on its surface, the friction is greatly reduced. In daily operation, no matter it is the slow expansion and contraction of the structure caused by the change of seasons and the temperature difference between day and night, or the violent shaking under extreme conditions such as earthquakes and strong winds, the erection body 3 can slide smoothly and freely on the polytetrafluoroethylene plate 10 with the help of the sliding shoes 5, which not only reduces the energy loss in the sliding process and reduces the additional wear on the node components caused by friction, but also extends the service life of the sliding shoes 5 and the sliding panel 6, and enables the erection body 3 to adapt to the structural deformation requirements more quickly and efficiently, and effectively breaks through the bottleneck of traditional one-way sliding nodes that limit the structural adaptability due to large friction resistance, and comprehensively guarantees the stable operation of the sliding nodes of the steel structure, and avoids the safety hazards caused by the reduction of the bearing capacity of high-strength bolts after repeated sliding.

[0045] In addition, in other embodiments, the polytetrafluoroethylene plate 10 can be replaced by an ultra-high molecular weight polyethylene plate, and the ultra-high molecular weight polyethylene plate is pasted on the stainless steel plate 9. This material also has an extremely low friction coefficient, which can ensure the smooth sliding of the sliding shoe 5, and has excellent performance in wear resistance and weather resistance, and is particularly suitable for construction projects under harsh environmental conditions, such as high humidity and high salinity environments at the seaside or areas with serious industrial pollution. Although its cost is relatively high, from the perspective of long-term maintenance and service life, the comprehensive benefits are considerable. In addition, in buildings with special requirements for fire resistance, the sliding panel 6 can adopt a composite structure of ceramic fiberboard and stainless steel plate 9, because the ceramic fiberboard has excellent fireproof and heat insulation performance, which can effectively block heat transfer when a fire occurs, protect the steel structure body and the erection body 3, and ensure that the node can still maintain normal working state within a certain period of time, and the stainless steel plate 9 provides basic load-bearing and wear-resistant functions. In other words, whether it is set as a polytetrafluoroethylene plate 10 or an ultra-high molecular weight polyethylene plate or a composite structure of a ceramic fiberboard and a stainless steel plate 9, it belongs to the protection scope of this embodiment.

[0046] The connection relationship between the steel beam 4 and the sliding shoe 5 of this embodiment is described in detail below.

[0047] like Figures 1 to 3 As shown, in some embodiments, the erection body 3 includes a steel beam 4 , and the sliding shoe 5 is welded to the bottom of the steel beam 4 .

[0048] Specifically, in this embodiment, those skilled in the art can understand that, on the one hand, the sliding shoe 5 and the steel beam 4 can be welded to form a solid whole, and no relative displacement or looseness will occur between the two during the force-bearing process. When the erection body 3 is subjected to vertical loads, such as the deadweight of the roof, snow load, etc., the external force can be reliably transmitted from the sliding shoe 5 to the steel beam 4 through the welding part, thereby ensuring the vertical stability of the steel structure; when facing the sliding demand caused by temperature changes, earthquakes, etc. in the horizontal direction, the stable connection can ensure the coordinated movement of the sliding shoe 5 and the steel beam 4, avoiding the situation of structural damage due to the weakness of the connection part, and effectively solving the problem that the traditional one-way sliding node connection is unreliable and easy to fail under complex working conditions.

[0049] The types and detailed structures of the steel beam 4 of this embodiment are described in detail below.

[0050] like Figures 1 to 3 As shown, in some embodiments, the steel beam 4 is an H-shaped steel beam 4, and the H-shaped steel beam 4 includes a web 11 and a flange 12. Vertical stiffening ribs 13 are provided on both sides of the web 11 of the steel beam 4 at positions corresponding to the sliding shoes 5.

[0051] Specifically, in this embodiment, those skilled in the art can understand that, on the one hand, the selected steel beam 4 is an H-shaped steel beam 4, because the unique structure of the H-shaped steel beam 4 plays a key role. The web 11 included in the H-shaped steel beam 4 mainly bears the vertical shear force. In large-span and ultra-long structures, due to the complex distribution of vertical loads, the web 11 can evenly disperse the vertical shear force with its high shear resistance to prevent excessive local shear force from causing structural damage; the flange 12 of the H-shaped steel beam 4 focuses on bending resistance. When the erection body 3 is subjected to eccentric loads, such as wind loads blowing unevenly on the roof, or when bending moments are generated by the action of the limit baffle 7 during the sliding process, the flange 12 of the H-shaped steel beam 4 can use its own good bending resistance to effectively resist bending deformation and maintain the mechanical properties of the steel beam 4 and even the entire erection body 3, thereby providing solid support for the steel structure sliding node to adapt to the complex and changeable stress environment, thereby overcoming the limitations of the traditional one-way sliding node support structure that is insufficient in strength and difficult to cope with complex stress, and comprehensively ensuring the reliable operation of the sliding node, while avoiding the safety risks caused by the reduction in the bearing capacity of high-strength bolts. On the other hand, the vertical stiffening ribs 13 are like adding two solid "shields" to the web 11 of the steel beam 4. In actual working conditions, when the erection body 3 encounters an emergency, such as a strong earthquake causing the building to shake violently, or a large temperature change caused by the change of seasons, causing the sliding shoe 5 to apply uneven lateral force to the web 11, these vertical stiffening ribs 13 can effectively share and resist these lateral forces, prevent the web 11 from buckling and deforming due to excessive local force, ensure the stability of the overall structure of the steel beam 4, and effectively solve the problem of local instability of traditional unidirectional sliding node support structures under complex forces.

[0052] Of course, the above description is not restrictive. In some alternative embodiments, the H-shaped steel beam 4 can be replaced by a hollow truss steel beam 4. The hollow truss steel beam 4 has a relatively light weight, which can further reduce the load effect caused by the weight in a large-span structure. In addition, its internal hollow structure is convenient for arranging various pipelines and improving the utilization rate of building space. In other words, whether the steel beam 4 is an H-shaped steel beam 4 or a hollow truss steel beam 4, it belongs to the protection scope of this embodiment.

[0053] The reinforcement of the steel beam 4 and the sliding shoe 5 of this embodiment is described in detail below.

[0054] like Figures 1 to 3 As shown, in some embodiments, there are at least two vertical stiffening ribs 13 , the thickness of the vertical stiffening ribs 13 is the same as the thickness of the flange 12 , and the thickness of the sliding shoe 5 is the same as the thickness of the web 11 .

[0055] In this embodiment, it can be understood by those skilled in the art that at least two vertical stiffening ribs 13 are provided, which work together to greatly enhance the stiffness of the web 11 area. This means that in daily operation and under extreme working conditions, the steel beam 4 can transfer vertical loads more smoothly and efficiently when carrying the weight of the roof system and ancillary facilities, as well as when dealing with the forces generated by structural deformation in the horizontal direction, so that the entire steel structure sliding node can maintain a reliable working state in a complex stress environment, laying a solid foundation for overcoming the safety risks caused by the insufficient structural stiffness, easy deformation, and reduced bearing capacity of high-strength bolts of traditional one-way sliding nodes. In addition, the thickness of the vertical stiffening rib 13 is consistent with that of the flange 12, so that the stress distribution of the entire steel beam 4 is more uniform during the stress process. When bearing vertical loads, such as the dead load and live load of the roof, and additional forces caused by structural deformation in the horizontal direction, the vertical stiffening ribs 13 can cooperate with the web 11 to better bear and disperse stress, avoid stress concentration in local areas, ensure the integrity and stability of the steel beam 4 structure, and effectively overcome the problem of easy damage caused by the inconsistent thickness of each component and uneven stress distribution in the traditional one-way sliding node support structure; on the other hand, the thickness of the sliding shoe 5 is the same as that of the web 11, and the two can achieve a smoother and more efficient transition during the force transmission process. Whether it is the vertical force transmitted from the sliding shoe 5 to the web 11, or the lateral force transmitted due to friction during horizontal sliding, the same thickness reduces the stress concentration caused by thickness mutation, allowing the erection body 3 to operate stably under various working conditions, providing a strong guarantee for solving the safety risks caused by the difference in thickness of the connection parts, poor force transmission, and reduced bearing capacity of high-strength bolts in traditional one-way sliding nodes.

[0056] The structural details of the limit baffle 7 of this embodiment are described in detail below.

[0057] like Figures 1 to 3 As shown, in some embodiments, the limit baffle 7 includes an X-direction limit steel plate 14 and a Y-direction limit steel plate 15, the X-direction limit steel plate 14 limits the sliding distance of the sliding shoe 5 on the sliding panel 6 along the X direction, and the Y-direction limit steel plate 15 limits the sliding distance of the sliding shoe 5 on the sliding panel 6 along the Y direction.

[0058] In this embodiment, it can be understood by those skilled in the art that, on the one hand, the X-direction limiting steel plate 14 is like a precise "horizontal guideline". When the steel structure has a displacement tendency in the X direction due to factors such as temperature changes and wind force in daily use, it can timely and effectively limit the sliding distance of the sliding shoe 5 on the sliding panel 6 in the X direction, avoid excessive deviation of the erection body 3 from the predetermined position, prevent collision and friction with surrounding components due to excessive displacement, ensure the stability of the entire structural system in the X direction, and overcome the problem that traditional unidirectional sliding nodes lack multi-directional limiting and are prone to loss of control in a single direction. on the other hand, the Y-limiting steel plate 15 is like a reliable "longitudinal guideline". When encountering extreme working conditions such as earthquakes and uneven settlement, which cause the structure to deform greatly along the Y direction, it can strictly limit the sliding range of the sliding shoe 5 in the Y direction, ensuring that the erection body 3 is always in a safe and controllable area, maintaining the regularity of the structure in the Y direction, and building a solid defense line to solve the problems of insufficient limiting capacity of traditional unidirectional sliding nodes, potential safety hazards caused by complex deformation, and unreliable connection caused by the reduced bearing capacity of high-strength bolts, thereby ensuring the stable operation of the sliding nodes of the steel structure in all directions.

[0059] The reinforcement of the limit baffle 7 of this embodiment is described in detail below.

[0060] like Figures 1 to 3 As shown, in some embodiments, an X-direction limiting steel plate 14 is welded with an X-direction limiting steel plate stiffening rib 16 , and a Y-direction limiting steel plate 15 is welded with a Y-direction limiting steel plate stiffening rib 17 .

[0061] Specifically, in the present embodiment, those skilled in the art can understand that, by welding the X-direction limiting steel plate stiffening rib 16 to the X-direction limiting steel plate 14, on the one hand, when the steel structure encounters extreme lateral loads such as strong winds and earthquakes, the X-direction limiting steel plate 14 is subjected to a strong impact force from the sliding shoe 5. At this time, the X-direction limiting steel plate stiffening rib 16 effectively enhances the bending resistance of the X-direction limiting steel plate 14 by virtue of its own high-strength characteristics, so that it can resist the impact force, prevent the X-direction limiting steel plate 14 from bending and deforming due to excessive force, ensure that it accurately limits the sliding distance of the sliding shoe 5 in the X direction, and ensure that the entire structure is in the X direction. The upward limit reliability overcomes the problem that the limit components of traditional one-way sliding nodes are easily damaged and cannot effectively cope with complex external forces; on the other hand, the evenly spaced X-direction limit steel plate stiffening ribs 16 (20mm thick × 80mm wide × 100mm long, set at intervals of 150mm in the X direction) can optimize the force distribution of the X-direction limit steel plate 14, and disperse the concentrated impact force to a larger range, so that the X-direction limit steel plate 14 is more evenly stressed, further improving its stability and durability, and providing strong support for solving the safety hazards caused by the weak limit device and the reduced bearing capacity of high-strength bolts in traditional one-way sliding nodes. Similarly, for the Y-direction limiting steel plate 15 welded with the Y-direction limiting steel plate stiffening rib 17, on the one hand, when facing extreme working conditions such as vertical vibration caused by earthquakes and vertical dislocation caused by uneven foundation settlement, when the Y-direction limiting steel plate 15 is subjected to huge vertical force, the Y-direction limiting steel plate stiffening rib 17 plays a key strengthening role, greatly enhancing the compressive capacity of the Y-direction limiting steel plate 15, avoiding it from being crushed, and improving the stability of the steel structure in the Y direction; on the other hand, the specific size (20mm thick × 55mm wide × 100mm long, set at intervals of 150mm in the Y direction) and the interval of the Y-direction limiting steel plate stiffening rib 17 also make the Y-direction limiting steel plate 15 more evenly stressed, extend its service life, and comprehensively guarantee the safe and stable operation of the sliding nodes of the steel structure under complex stress environments.

[0062] The arrangement of the limit baffle 7 of this embodiment is described in detail below.

[0063] like Figures 1 to 3 As shown, in some embodiments, the dimensions of the X-direction limiting steel plate stiffening rib 16 are 20 mm thick × 80 mm wide × 100 mm long, and the X-direction limiting steel plate stiffening rib 16 is arranged at intervals of 150 mm along the X direction, the dimensions of the Y-direction limiting steel plate stiffening rib 17 are 20 mm thick × 55 mm wide × 100 mm long, and the Y-direction limiting steel plate stiffening rib 17 is arranged at intervals of 150 mm along the Y direction, the dimensions of the X-direction limiting steel plate 14 are 20 mm thick × 100 mm wide × 600 mm long, and the dimensions of the Y-direction limiting steel plate 15 are 20 mm thick × 100 mm wide × 800 mm long.

[0064] Specifically, in the present embodiment, those skilled in the art can understand that, by specifying that the dimensions of the X-direction limiting steel plate stiffening ribs 16 are 20 mm thick × 80 mm wide × 100 mm long and are arranged at intervals of 150 mm in the X direction, on the one hand, such specific dimensions and spacing layouts enable the X-direction limiting steel plate stiffening ribs 16 to provide precise and efficient bending reinforcement effects for the X-direction limiting steel plate 14 with just the right strength and distribution density when facing extreme lateral load impacts such as strong winds and earthquakes. The layout of the stiffening ribs with an interval of 150 mm ensures the uniformity of external force transmission, avoiding material waste and construction difficulties caused by too dense stiffening ribs, and preventing ineffective reinforcement due to too sparse stiffening ribs, thereby resisting the impact force transmitted from the sliding shoe 5, ensuring that the X-direction limit steel plate 14 always maintains a good plane state, and accurately limits the sliding distance of the sliding shoe 5 in the X direction; on the other hand, the precise size setting allows the X-direction limit steel plate stiffening rib 16 to have good stability itself. During long-term use, it is not easy to be deformed or damaged due to environmental erosion and repeated force, which greatly extends its service life and solves the safety hazards that may be caused by insufficient durability of the limit device. Similarly, for the Y-direction limit steel plate stiffening rib 17, its size is 20mm thick × 55mm wide × 100mm long and is set at an interval of 150mm in the Y direction. On the one hand, when encountering extreme working conditions such as earthquake vertical vibration and uneven foundation settlement, the Y-direction limit steel plate 15 is subjected to huge vertical force. The stiffening ribs of this size and interval can adapt to the force characteristics of the Y-direction limit steel plate 15 and effectively enhance its compressive resistance. At the same time, the Y-direction limit steel plate 15 accurately limits the sliding range of the sliding shoe 5 in the Y direction and maintains the stability of the steel structure in the Y direction; on the other hand, the reasonable size and interval ensure the reliability of the Y-direction limit steel plate stiffening rib 17 in a long-term complex force environment, reduce the frequency of maintenance, and lay a solid foundation for the steel structure sliding node to cope with various challenges in the vertical dimension, ensuring the safe operation of the sliding node. In addition, the size of the X-direction limit steel plate 14 is limited to 20mm thick × 100mm wide × 600mm long, and the size of the Y-direction limit steel plate 15 is limited to 20mm thick × 100mm wide × 800mm long, so that the limit steel plate has sufficient strength to resist the impact of the sliding shoe 5, and can also provide a suitable limit range according to the deformation characteristics and force requirements of the steel structure in different directions. It will not effectively restrict the displacement of the sliding shoe 5 due to too small size, causing risks such as structural collision, nor will it cause material redundancy, increase costs and installation difficulties due to too large size, ensuring that the steel structure sliding node achieves a balance between economy and practicality on the basis of meeting the safety performance requirements, and solves a series of problems caused by the unreasonable limit design of the traditional one-way sliding node and the reduction of the bearing capacity of the high-strength bolts.

[0065] The support body 1 of this embodiment is described in detail below.

[0066] like Figures 1 to 3As shown, in some embodiments, the supporting body 1 is a concrete column or a steel column.

[0067] Specifically, in this embodiment, it can be understood by those skilled in the art that, on the one hand, when the concrete column is used as the supporting body 1, it has the advantages of relatively low cost, convenient material acquisition, and good fire resistance. In some construction projects with strict cost control and high fire protection requirements, the use of concrete columns as the supporting body 1 can effectively reduce the project cost on the basis of meeting the structural support requirements, and at the same time provide a reliable vertical bearing foundation for the entire steel structure sliding node to ensure the stability of the structure in sudden situations such as fire; on the other hand, the steel column has the characteristics of high strength, light weight, convenient construction, and recyclability. When applied to high-rise, large-span and other building scenes with strict restrictions on the deadweight of the structure, or with tight construction schedules and high requirements for environmental protection, the steel column can rely on its own advantages to quickly and efficiently build the framework of the supporting body 1, provide accurate and stable connection support for the erection body 3, ensure the smooth operation of the sliding node of the steel structure, better adapt to complex and changeable construction conditions, solve a series of safety hazards and usage limitations caused by the poor adaptability of the supporting body 1 and the reduction of the bearing capacity of high-strength bolts, and provide strong support for the diversified design and sustainable development of building structures.

[0068] like Figures 1 to 3 As shown, the installation process of a steel structure sliding node with a limiting device in this embodiment is as follows:

[0069] 1. Preparation of the support body 1: According to the requirements of the building design, determine whether to use concrete columns or steel columns as the support body 1. If concrete columns are used, they are cast on site according to the conventional concrete pouring construction process to ensure that the size, strength and other indicators of the concrete columns meet the design requirements. After the concrete columns reach a certain strength, subsequent construction is carried out; if steel columns are used, they are prefabricated in the factory, and the component accuracy of the steel columns is ensured through high-precision cutting, welding and other processes. After being transported to the construction site, they are accurately hoisted into place using cranes and other equipment, and reliably connected to the foundation to ensure their verticality and stability.

[0070] 2. Installation of bracket 2: Fix bracket 2 by welding or high-strength bolt connection on the side of the completed support body 1 according to the designed position. When welding, strictly control the welding process parameters to ensure that the bracket 2 is firmly connected to the support body 1, and the weld quality must meet the requirements of relevant specifications; when high-strength bolts are used for connection, it is necessary to ensure that the bolt specifications and tightening torque reach the specified value to prevent the bracket 2 from loosening.

[0071] 3. Setting of embedded parts 8: Determine the installation position of embedded parts 8 on the corbel 2 in advance, accurately position the embedded parts 8, and then securely fix them by welding or chemical anchor bolts 18 to ensure that the embedded parts 8 do not move during the subsequent construction process. The size and material of the embedded parts 8 must meet the requirements of bearing the sliding panel 6 and erecting the main body 3, providing a solid foundation for the subsequent welding of the sliding panel 6.

[0072] 4. Installation of sliding panel 6: Paste the stainless steel plate 9 and the polytetrafluoroethylene plate 10 together as required to form the sliding panel 6, and ensure that they are firmly fixed. Weld the assembled sliding panel 6 to the embedded part 8. During the welding process, ensure that the surface of the sliding panel 6 is flat to create conditions for the smooth sliding of the erection body 3, so that the sliding shoe 5 can slide freely on the polytetrafluoroethylene plate 10.

[0073] 5. Assemble the erection body 3: Weld and assemble the steel beam 4 and the sliding shoe 5 in the factory or construction site. The steel beam 4 is an H-shaped steel beam 4. During welding, the connection strength between the sliding shoe 5 and the bottom of the steel beam 4 is ensured to ensure that the two form a stable whole. At least two vertical stiffening ribs 13 are installed on both sides of the web 11 of the H-shaped steel beam 4 corresponding to the position of the sliding shoe 5, and the thickness of the vertical stiffening rib 13 is ensured to be the same as that of the flange 12, and the thickness of the sliding shoe 5 is the same as that of the web 11, so as to enhance the structural stability and force transmission performance.

[0074] 6. Installation of the erection body 3: Place one end of the erection body 3 on the corbel 2 on which the sliding panel 6 has been installed, and place the other end on another supporting body 1. Adjust the position of the erection body 3 to make it at the horizontal degree and elevation position required by the design, ensure good contact between the erection body 3 and the supporting body 1 and the sliding panel 6, and avoid hanging, deviation, etc.

[0075] 7. Installation of limit baffle 7: According to the design requirements, the X-direction limit steel plate 14 and the Y-direction limit steel plate 15 are installed on the periphery of the sliding panel 6 and fixed by welding to ensure the accurate position of the limit baffle 7. For the X-direction limit steel plate 14, the X-direction limit steel plate stiffening rib 16 is welded, and its size is 20mm thick × 80mm wide × 100mm long, and it is set at intervals of 150mm in the X direction; for the Y-direction limit steel plate 15, the Y-direction limit steel plate stiffening rib 17 is welded, and its size is 20mm thick × 55mm wide × 100mm long, and it is set at intervals of 150mm in the Y direction, thereby enhancing the bending and compression resistance of the limit baffle 7, so that it can effectively limit the sliding distance of the sliding shoe 5 in the corresponding direction, and ensure the safe operation of the entire steel structure sliding node.

[0076] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope of the present invention.
