Description

Technical Field

[0001] This utility model relates to the field of building construction equipment technology, and specifically to a novel flexible connection structure. Background Technology

[0002] ALC (autoclaved aerated concrete) panels are widely used as enclosure walls in steel frame structures due to their lightweight, high strength, and excellent thermal insulation properties. However, in existing technologies, ALC panels are typically connected to the main steel structure using a rigid connection method, which has many shortcomings in practical applications.

[0003] Under minor earthquakes, due to the rigid connection between the ALC slab and the steel frame, the ALC slab often participates in the overall structural stress process prematurely. This leads to cracking due to displacement differences and stress concentration, affecting the building's functionality and aesthetics. Under major earthquakes, the steel frame structure relies on its good ductility to dissipate seismic energy and achieve seismic resistance. However, the rigid connection of the ALC slab restricts the plastic deformation capacity of the steel frame, causing stress concentration. This not only accelerates the failure of the ALC slab but also reduces the ductility and seismic performance of the overall structure. These problems are particularly prominent in earthquake-prone areas, seriously threatening the safety and durability of buildings. Utility Model Content

[0004] In view of this, the present invention provides a novel flexible connection structure to solve the problems of poor seismic performance, stress concentration, poor safety and durability when connecting ALC plates to steel frames in the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: Firstly, this utility model provides a novel flexible connection structure applied to the connection between an ALC plate and a steel frame structure. The steel frame structure includes an upper steel beam, a lower steel beam, and steel columns for the upper and lower steel beams. The structure comprises: a first connecting plate assembly, a second connecting plate assembly, a first elastic element, a second elastic element, and a sliding element. The first connecting plate assembly is disposed on the lower steel beam, the second connecting plate assembly is disposed on the upper steel beam, and the ALC plate is located between the first connecting plate assembly and the second connecting plate assembly. The first connecting plate assembly and the second connecting plate assembly are fixedly connected to the front side of the ALC plate. The ALC plate is positioned to limit its position in the front-to-back direction. The first elastic member is vertically disposed between the steel column and the side of the ALC plate near the steel column to provide a horizontal elastic force to the ALC plate. The second elastic member is disposed between the first connecting plate assembly and the lower end face of the ALC plate to provide a vertical elastic force to the ALC plate. The sliding member is disposed between the second connecting plate assembly and the upper end face of the ALC plate, with the upper end face of the sliding member rigidly connected to the second connecting plate assembly, and the upper end face of the ALC plate and the lower end face of the sliding member slidably connected in the horizontal direction.

[0006] It has the following advantages: The ALC plate is fixed in the front-to-back direction by the first and second connecting plate assemblies, effectively preventing displacement of the ALC plate due to external forces during use, thus improving the overall structural stability and installation accuracy. The first elastic element is vertically positioned between the steel column and the side of the ALC plate, providing horizontal elasticity to the ALC plate under horizontal external forces such as earthquakes or wind loads, buffering and dispersing stress concentration caused by external forces, and improving the seismic performance and energy absorption capacity of the connection node. The second elastic element is positioned between the first connecting plate assembly and the lower end face of the ALC plate to provide vertical elastic support to the ALC plate. This prevents cracking or damage to the ALC plate due to rigid connections when temperature or vertical loads change, enhancing the durability and safety of the structure. A sliding element is positioned between the second connecting plate assembly and the upper end face of the ALC plate. The sliding element and the ALC plate slide horizontally, allowing the ALC plate to adapt to minor displacements caused by temperature differences, settlement, or deformation in the horizontal direction, further reducing stress concentration caused by displacement constraints and improving the overall flexibility of the structure. This utility model significantly improves the seismic performance, safety, and service life of the connection between the ALC plate and the steel frame structure through a multi-directional flexible connection design, solving problems such as stress concentration, excessive connection rigidity, and poor durability. It has good engineering application prospects and promotion value.

[0021] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] Reference Figure 1 , Figure 2 and Figure 3 As shown, in a first aspect, this utility model provides a novel flexible connection structure for connecting an ALC plate 2 to a steel frame structure 1. The steel frame structure 1 includes an upper steel beam 13, a lower steel beam 12, and steel columns 11 for the upper steel beam 13 and the lower steel beam 12. The structure includes: a first connecting plate assembly 5, a second connecting plate assembly 4, a first elastic element 3, a second elastic element 6, and a sliding element 8. The first connecting plate assembly 5 is disposed on the lower steel beam 12, and the second connecting plate assembly 4 is disposed on the upper steel beam 13. The ALC plate 2 is located between the first connecting plate assembly 5 and the second connecting plate assembly 4. The first elastic member 3 is fixedly connected to the front of the ALC plate 2 to limit the position of the ALC plate 2 in the front-back direction; the first elastic member 3 is vertically disposed between the steel column 11 and the side of the ALC plate 2 near the steel column 11 to provide horizontal elastic force to the ALC plate 2; the second elastic member 6 is disposed between the first connecting plate group 5 and the lower end face of the ALC plate 2 to provide vertical elastic force to the ALC plate 2; the sliding member 8 is disposed between the second connecting plate group 4 and the upper end face of the ALC plate 2, the upper end face of the sliding member 8 is rigidly connected to the second connecting plate group 4, and the upper end face of the ALC plate 2 and the lower end face of the sliding member 8 are slidably connected in the horizontal direction.

[0023] Specifically, the first connecting plate group 5 and the second connecting plate group 4 fix the ALC plate 2 in the front-to-back direction, effectively preventing the ALC plate 2 from shifting due to external forces during use, thus improving the overall structural stability and installation accuracy. The first elastic element 3 is vertically positioned between the steel column 11 and the side of the ALC plate 2, providing horizontal elasticity to the ALC plate 2 under horizontal external forces such as earthquakes or wind loads, buffering and dispersing stress concentration caused by external forces, and improving the seismic performance and energy absorption capacity of the connection node. The second elastic element 6 is positioned between the first connecting plate group 5 and the lower end face of the ALC plate 2 to provide vertical elastic support to the ALC plate 2. When temperature or vertical load changes, it prevents the ALC plate 2 from cracking or being damaged due to rigid connections, enhancing the durability and safety of the structure. The sliding member 8 is located between the second connecting plate group 4 and the upper end face of the ALC plate 2. The sliding member 8 and the ALC plate 2 are slidably connected in the horizontal direction, allowing the ALC plate 2 to adapt to small displacements caused by temperature differences, settlement, or deformation in the horizontal direction. This further reduces stress concentration caused by displacement constraints and improves the overall flexibility of the structure. This utility model, through its multi-directional flexible connection design, significantly improves the seismic performance, safety, and service life of the connection between the ALC plate 2 and the steel frame structure 1, solving problems such as stress concentration, excessive connection rigidity, and poor durability. It has good engineering application prospects and promotional value.

[0024] Understandably, this invention incorporates a first elastic element 3, a second elastic element 6, and a sliding element 8 in the vertical and horizontal directions, respectively, to fully absorb energy from external forces such as earthquakes, disperse concentrated stress, and prevent brittle failure caused by rigid connections, effectively improving the overall structure's seismic toughness and safety. The cooperation between the sliding element 8 and the second elastic element 6 fully releases structural displacement caused by temperature changes and foundation settlement, preventing early damage phenomena such as cracking and detachment of the ALC panel 2, and greatly improving the durability and service life of the connection nodes. The multiple sliding connections and flexible elements in this invention effectively compensate for on-site construction errors and structural dimensional tolerances, reducing installation difficulty, improving assembly efficiency and connection quality, and exhibiting good on-site adaptability and construction convenience. The reasonable matching of elastic modulus and thickness of each elastic element ensures sufficient flexibility while possessing good load-bearing capacity, resulting in a smooth and stable overall connection that meets the comprehensive requirements of high-performance connection nodes for large-span, lightweight wall panel systems in actual engineering projects. The novel flexible connection structure of this utility model is suitable for connecting various ALC plates and steel structure systems, and has wide application value, especially in high-rise buildings, prefabricated buildings, and buildings in seismic fortification zones.

[0025] In a first aspect embodiment of the present invention, the novel flexible connection structure further includes a third elastic member 7, which is disposed between the lower end face of the second connecting plate group 4 and the upper end face of the sliding member 8. The third elastic member 7 is rigidly connected to the lower end face of the ALC plate, and the upper end face of the third elastic member 7 is slidably connected to the lower end face of the sliding member 8 in the horizontal direction.

[0026] Specifically, when there is an installation gap between the lower end face of the sliding member 8 and the upper end face of the ALC plate 2, to ensure structural compactness and force balance, the thickness of the third elastic member 7 can be selected according to the size of the installation gap. The third elastic member 7 is then placed between the sliding member 8 and the ALC plate 2, so that the lower end face of the third elastic member 7 is rigidly connected to the upper end face of the ALC plate 2, and the upper end face of the third elastic member 7 is slidably connected to the lower end face of the sliding member 8 in the horizontal direction. By setting the third elastic member 7, not only is the buffering performance of the sliding member 8 increased, but it also provides energy dissipation buffering for instantaneous impact loads during sliding, further improving the system's seismic energy dissipation capacity and service life.

[0027] In a first aspect embodiment of the present invention, the first connecting plate group 5 includes a first connecting plate 51 and a second connecting plate 52. The lower end face of the first connecting plate 51 is rigidly connected to the upper end face of the lower steel beam 12. One end of the second connecting plate 52 is slidably connected to the first connecting plate 51 in the horizontal direction. The other end of the second connecting plate 52 is fixedly connected to the front side of the ALC plate 2 by a first fastener. The second elastic member 6 is disposed between the upper end face of the first connecting plate 51 and the lower end face of the ALC plate 2.

[0028] In a first aspect of this utility model, the first connecting plate 51 includes a first horizontal portion and a first vertical portion that are perpendicular to and connected to each other. The lower end face of the first horizontal portion is rigidly connected to the upper end face of the lower steel beam 12. The front side of the ALC plate 2 abuts against the inner side of the first vertical portion. The second connecting plate 52 includes a first connecting portion and a second connecting portion that are connected in a stepped manner. The first connecting portion is slidably connected to the outer side of the first vertical portion in the horizontal direction. The second connecting portion is fixedly connected to the front side of the ALC plate 2 by fasteners. The second elastic member 6 is disposed between the upper end face of the first horizontal portion and the lower end face of the ALC plate 2.

[0029] In a first aspect of the present invention, the second connecting plate group 4 includes a third connecting plate 41 and a fourth connecting plate 42. The upper end face of the third connecting plate 41 is rigidly connected to the lower end face of the upper steel beam 13. One end of the fourth connecting plate 42 is slidably connected to the third connecting plate 41 in the horizontal direction. The other end of the fourth connecting plate 42 is fixedly connected to the front side of the ALC plate 2 by a second fastener. The sliding member 8 is disposed between the lower end face of the third connecting plate 41 and the upper end face of the ALC plate 2.

[0030] In a first aspect of this utility model, the second connecting plate group 4 includes a third connecting plate 41 and a fourth connecting plate 42. The third connecting plate 41 includes a second horizontal portion and a second vertical portion that are perpendicular to each other and connected. The upper end face of the second horizontal portion is rigidly connected to the lower end face of the upper steel beam 13. The front side of the ALC plate 2 abuts against the inner side face of the second vertical portion. The fourth connecting plate 42 includes a third connecting portion and a fourth connecting portion that are connected in a stepped manner. The third connecting portion abuts against the outer side face of the second vertical portion in the horizontal direction. The fourth connecting portion is connected to the front side face of the ALC plate 2 by a second fastener. The sliding member 8 is disposed between the lower end face of the second horizontal portion and the upper end face of the ALC plate 2.

[0031] Specifically, the first connecting plate assembly 5 includes a first connecting plate 51 and a second connecting plate 52. The first connecting plate 51 has a first horizontal portion and a first vertical portion. The lower end face of the first horizontal portion is rigidly connected to the upper end face of the lower steel beam 12 by laying a rigid connecting layer, wherein the rigid connecting layer is cement mortar; the inner side face of the first vertical portion abuts against the front side face of the ALC plate 2, thereby limiting the position of the ALC plate 2 in the front-back direction. One end of the second connecting plate 52 is slidably connected to the first vertical portion in the horizontal direction, and the other end is fixedly connected to the front side face of the ALC plate 2 by a first fastener. By setting the second connecting plate 52 and the first vertical portion to be slidably connected, the concentrated stress in the horizontal direction is effectively decomposed, thereby improving the seismic performance.

[0032] The second connecting plate assembly 4 includes a third connecting plate 41 and a fourth connecting plate 42. The third connecting plate 41 has a second horizontal portion and a second vertical portion. The upper end face of the second horizontal portion is rigidly connected to the lower end face of the upper steel beam 13 by laying a rigid connecting layer. The inner side face of the second vertical portion abuts against the front side face of the ALC plate 2, serving as an auxiliary limiting function for the ALC in the front-rear direction. The fourth connecting plate 42 has a stepped third connecting portion and a fourth connecting portion. The third connecting portion is slidably connected to the second vertical portion in the horizontal direction, and the fourth connecting portion is fixedly connected to the front side face of the ALC plate 2 by a second fastener. This sliding connection structure can also decompose the concentrated stress in the transverse horizontal direction, improving seismic performance.

[0033] It is understandable that both the first and second fasteners are fastening bolts.

[0034] In the first aspect of this utility model, the first elastic member 3, the second elastic member 6 and the third elastic member 7 are all plate-shaped structures.

[0035] In a first aspect of this invention, the thickness of the first elastic member 3 is greater than the thickness of the second elastic member 6.

[0036] In a first aspect embodiment of the present invention, the elastic modulus of the first elastic element 3, the second elastic element 6, and the third elastic element 7 is 0.7-1 MPa.

[0037] Specifically, regarding the vertical flexible support, the second elastic element 6 is located between the upper end face of the first horizontal plane and the lower end face of the ALC plate 2. It adopts a plate-like structure, which can provide appropriate vertical elastic displacement compensation under conditions of temperature change, vertical load change or slight settlement. This effectively avoids quality problems such as cracking and plate falling off caused by the vertical deformation limitation of the ALC plate 2, and extends the service life of the plate.

[0038] In terms of horizontal flexible support, the first elastic element 3 is set vertically between the steel column 11 and the side of the ALC plate 2. It is made of plate-shaped elastic material and can provide flexible buffer energy absorption under horizontal external forces such as wind load and seismic load, reduce stress concentration at the connection node, and improve the seismic performance and safety performance of the overall structure.

[0039] To further enhance the performance of the flexible connection, a sliding member 8 is disposed between the lower end face of the third connecting plate 41 and the upper end face of the ALC plate 2. The lower end face of the sliding member 8 is rigidly connected to the upper end face of the ALC plate 2, while its upper end face is slidably connected to the third connecting plate 41 in the horizontal direction. It can slide freely when micro-displacement of the structure occurs, mitigating horizontal displacement changes caused by factors such as temperature expansion and contraction, and foundation settlement, and effectively preventing the plate from cracking or deforming due to rigid constraints.

[0040] It is understood that the elastic modulus of the first elastic element 3, the second elastic element, and the third elastic element 7 is preferably 0.7 to 1 MPa, which can provide sufficient flexible displacement capacity and ensure the stability of the overall load-bearing capacity of the connection node. Among them, the thickness of the first elastic element 3 is preferably greater than the thickness of the second elastic element 6, so as to meet its requirements for bearing greater horizontal deformation and energy dissipation.

[0041] Secondly, this utility model also provides a construction method for the connection node between the ALC plate 2 and the steel frame structure 1, which applies a novel flexible connection structure and includes the following steps: 1. Erect a steel frame structure; Install the first connecting plate group 5 and the second connecting plate group 4, lay a rigid connecting layer on the lower end face of the upper steel beam 13 and the upper end face of the lower steel beam 12, and rigidly connect the first connecting plate group 5 and the second connecting plate group 4 to the lower steel beam 12 and the upper steel beam 13 respectively. Install the second elastic element 6 and the sliding element 8. Install the second elastic element 6 on the first connecting plate group 5 and install the sliding element 8 on the upper end face of the second connecting plate group 4. Install the first elastic element 3 on both sides of the steel column 11; Install ALC plate 2 and install ALC plate 2 inside steel frame structure 1; so that the upper end face of the second elastic member 6 is rigidly connected to the lower end face of ALC plate 2, the lower end face of the sliding member 8 is slidably connected to the upper end face of ALC plate 2 in the horizontal direction, and the side of ALC plate 2 opposite to the steel column 11 abuts against the first elastic member 3.

[0042] Specifically, after erecting the steel frame structure 1, the first connecting plate group 5 and the second connecting plate group 4 are installed first, and a rigid connection layer is set on the end face of the steel beam. This ensures a reliable connection between the connecting plate group and the steel frame, guarantees the positioning accuracy of the subsequent ALC plate 2 installation and the stability of the overall structure, and improves the safety and standardization of the construction process. The second elastic element 6 is pre-installed between the first connecting plate group 5 and the lower end face of the ALC plate 2, and a sliding element 8 is set on the lower end face of the second connecting plate group 4. This effectively guides and limits the installation position of the ALC plate 2, enabling the ALC plate 2 to be quickly and accurately positioned during hoisting and positioning, simplifying construction operations, reducing installation difficulty, and improving construction efficiency. After the ALC plate 2 is in place, the second elastic element 6 is rigidly connected to the lower end face of the ALC plate 2, and the sliding element 8 is slidably connected to the upper end face of the ALC plate 2 in the horizontal direction, thus forming flexible support in both the vertical and horizontal directions. This flexible connection structure can effectively absorb micro-displacements caused by temperature changes, structural settlement, or changes in external loads during subsequent use, avoiding stress concentration and improving the long-term durability and safety of the connection nodes. By installing the first elastic element 3 between the steel column 11 and the ALC plate 2, a flexible buffering effect can be provided in the horizontal direction, enhancing the structure's seismic energy dissipation capacity under horizontal external forces such as wind loads and seismic loads, improving the overall seismic performance and toughness of the structure, and reducing the risk of plate damage and detachment.

[0043] This construction method not only simplifies the construction process and effectively improves construction efficiency and installation accuracy, but also, by rationally configuring each elastic element and sliding component 8, takes into account both flexible buffering and rigid support. It improves the problems of complex construction, stress concentration and easy damage in the connection between ALC plate 2 and steel structure in the existing technology, and achieves the organic unity of efficient construction and high-performance connection. It has good promotion and application value and engineering practice significance.
