Description

Technical Field

[0001] This invention relates to the field of building engineering technology, and specifically to an exterior wall connection structure. Background Technology

[0002] Currently, in the construction of prefabricated steel structure buildings, the common practice is to directly adhere and anchor integrated insulation and decorative panels after the base layer of ALC (autoclaved aerated concrete) wall panels and surface mortar have been completed, thus forming a prefabricated steel structure facade. Each integrated insulation and decorative panel is typically anchored into the ALC wall panel using anchors and connected to the ALC wall panel via wet bonding. However, due to the relatively light weight and low strength of ALC wall panels, the anchoring points within the ALC wall panel are prone to cracking, affecting the overall structural performance of the wall.

[0003] Due to the region's high basic wind pressure, long hours of sunshine, and abundant rainfall, the integrated insulation and decorative panels are heavy and prone to instability in their connection with the base wall, leading to panel detachment and safety hazards. Furthermore, the base walls of existing steel-structure prefabricated buildings typically use ALC wall panels, which have poor crack resistance. When the anchors of the integrated insulation and decorative panels are directly fixed to the ALC wall panels, cracks can easily occur at the anchoring points, further causing partial or complete detachment of the integrated insulation and decorative panels.

[0004] In addition, the facades of existing steel-structure prefabricated buildings are usually spliced ​​together from multiple integrated insulation and decorative panels. After construction, due to the cumulative load effect from top to bottom, if one integrated insulation and decorative panel cracks or falls off due to poor connection or external force, it can easily drive adjacent panels, causing a large area of ​​the facade's integrated insulation and decorative panels to fall off, posing a significant safety risk. Summary of the Invention

[0026] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0027] Reference Figure 1 and Figure 2 As shown, the present invention provides an exterior wall connection structure, including: a floor slab 1, a base wall 2, a bracket structure 3, and a connection structure. The bracket structure 3 is disposed between two decorative walls and is fixedly connected to the floor slab 1. The bottom of the decorative wall is connected to the bracket structure 3 to facilitate the transfer of the cumulative load of the decorative wall to the floor slab 1. The connection structure passes through the decorative wall to connect with the base wall 2 to facilitate the fixing of the decorative wall to the base wall 2.

[0028] Specifically, the exterior wall connection structure provided by this invention, by setting a bracket structure 3 between two decorative walls and fixing the bracket structure 3 to the floor slab 1, allows the cumulative load of the decorative walls to be reliably transferred to the floor slab 1. This avoids the decorative walls being directly suspended from the base wall 2 or relying solely on adhesive bonding, thereby effectively improving the load-bearing capacity and overall stability of the exterior wall and reducing the risk of cracking and detachment of the decorative walls due to excessive load or external forces. Simultaneously, by connecting the decorative wall through the connecting structure and connecting it to the base wall 2, the decorative wall is stably positioned in the horizontal direction, further improving the wind pressure resistance and seismic performance of the exterior wall and enhancing safety. This invention effectively solves the problems of easy detachment and cracking of exterior walls and the significant safety risks in the prior art, and has the advantages of reasonable structure, reliable connection, and high safety performance.

[0029] In some embodiments of the present invention, the bracket structure 3 includes a mounting frame 31, a first fixing member 33 and a first fastener 32. The first fixing member 33 passes through the mounting frame 31 to fix the mounting frame 31 to the floor slab 1. The lower end of the decorative wall is connected to the first fastener 32, and the first fastener 32 is fixed on the mounting frame 31.

[0030] Specifically, the bracket structure 3 is designed to include a mounting frame 31, a first fixing member 33, and a first fastener 32. The first fixing member 33 passes through the mounting frame 31 and firmly fixes the mounting frame 31 to the floor slab 1, ensuring a reliable connection between the bracket structure 3 and the main structure. This allows it to withstand greater vertical and horizontal loads, improving the overall load-bearing capacity. Simultaneously, the lower end of the decorative wall is connected to the first fastener 32, which fixes the decorative wall to the bracket structure 3. This makes the installation positioning of the decorative wall more accurate, reduces construction errors, improves installation precision, and shortens and directs the force path of the decorative wall, thereby improving vibration and impact resistance and extending the service life of the structure.

[0031] In some embodiments of the present invention, the mounting bracket 31 includes a first vertical section and a first horizontal section connected to each other, a first fixing member 33 passes through the first vertical section and one end of it is fixedly connected to the floor slab 1, and a first fastener 32 is fixedly connected to the first horizontal section through a second fixing member 34.

[0032] Specifically, the mounting bracket 31 is constructed with a first vertical section and a first horizontal section. The first vertical section is used for a reliable connection to the floor slab 1 and bears the load from the direction of the floor slab 1; the first horizontal section is used for connection to the first fastener 32 and supports the bottom of the decorative wall. This three-dimensional L-shaped or inverted L-shaped structural design forms a stable triangular support system, improving the overall bending stiffness and shear strength of the bracket structure 3, and preventing deformation or displacement of the bracket under load. The first fastener 33 passes through the first vertical section and is fixedly connected to the floor slab 1, enhancing the longitudinal and lateral stability of the mounting bracket 31. The first fastener 32 is connected to the first horizontal section through the second fastener 34, making the connection between the decorative wall and the bracket more reliable and effectively avoiding safety hazards such as sagging, loosening, or falling off of the decorative wall during use.

[0033] In some embodiments of the present invention, the first fastener 32 is arranged in a horizontal direction so as to be parallel to the first horizontal segment, and a sealing layer is provided between the first fastener 32 and the decorative wall.

[0034] Specifically, the first fastener 32 is arranged horizontally and parallel to the first horizontal section, making the structural layout more rational. This facilitates the transfer of horizontal and wind loads borne by the decorative wall, reduces stress concentration, and improves the uniformity of structural stress. Simultaneously, a sealant layer is installed between the first fastener 32 and the decorative panel, effectively preventing the intrusion of external media such as rainwater and dust, preventing leakage and corrosion risks. This is particularly suitable for building facades that are exposed to wind and rain for extended periods, significantly improving the weather resistance, impermeability, and overall durability of the facade wall system.

[0035] In some embodiments of the present invention, the connection structure includes a second fastener 41, a third fastener 42, a third fixing member 43 and a fourth fixing member 44. The third fixing member 43 passes through the second fastener 41 to be adapted to fix one side of the second fastener 41 to the base wall 2. The third fastener 42 is fixedly connected to the second fastener 41 through the fourth fixing member 44.

[0036] Specifically, the connection structure is constructed by including a second fastener 41, a third fastener 42, a third fixing member 43, and a fourth fixing member 44, forming a multi-level, multi-point connection system. The third fixing member 43 reliably fixes the second fastener 41 to the base wall 2, ensuring that the connection system has excellent tensile strength and shear bearing capacity, adapting to various load conditions such as wind pressure, earthquakes, and temperature deformation. The fourth fixing member 44 connects the third fastener 42 to the second fastener 41, establishing a stable mechanical connection between the decorative wall and the base wall 2. This structure not only improves the connection reliability of the exterior wall but also reduces local stress concentration by dispersing stress transmission paths, enhancing the overall stability and durability of the exterior wall system.

[0037] In some embodiments of the present invention, the second fastener 41 includes a second vertical section and a second horizontal section, the third fastener 43 passes through the second vertical section and one end of it is fixedly connected to the base wall 2, and the third fastener 42 is arranged parallel to the second horizontal section.

[0038] This invention designs the second fastener 41 to include a second vertical section and a second horizontal section. The second vertical section enables direct fixation to the base wall 2, enhancing the vertical load-bearing capacity and pull-out resistance. The second horizontal section is arranged parallel to the third fastener 42. Through multi-faceted contact and increased in-plane stiffness, the connection area has better resistance to horizontal loads and optimizes the force transmission path, improving the overall structural stability of the connection area. This segmented design helps to reasonably distribute wind loads, seismic loads, and displacements caused by thermal expansion and contraction to the base wall 2 and the bracket structure 3, preventing fatigue damage or local cracking of the decorative wall during long-term use.

[0039] In some embodiments of the present invention, the first fastener 32, the second fastener 41 and the third fastener 42 are all made of metal or alloy.

[0040] Specifically, by selecting metal or alloy materials for the first fastener 32, the second fastener 41, and the third fastener 42, this invention endows the connectors with higher yield strength, tensile strength, and fatigue resistance, significantly improving the safety factor of the connectors under dynamic loads. Simultaneously, the metal or alloy materials possess excellent corrosion resistance and environmental adaptability, enabling long-term stable operation in harsh environments such as high humidity, high salinity, high temperature, and extreme cold, reducing maintenance frequency and improving the service life and economy of the exterior wall connection system.

[0041] In some embodiments of the present invention, a first waterproof gasket 35 is provided between the first fixing member 33 and the first vertical section; a second waterproof gasket 45 is provided between the third fixing member 43 and the second vertical section.

[0042] Specifically, by setting waterproof gaskets between the first fixing member 33 and the first vertical section, and between the third fixing member 43 and the second vertical section, the present invention can effectively seal the pores when the fixing member penetrates the component, blocking the penetration path of water vapor, rainwater and external moisture, preventing moisture from entering the floor slab 1 or the foundation wall 2, reducing the hidden dangers of internal steel corrosion, concrete carbonization and mold growth, especially for high-rise buildings with high requirements for exterior waterproof performance, thereby enhancing the waterproof sealing performance and durability of the entire connection system.

[0043] It is understandable that both the first fastener 33 and the second fastener 34 are expansion bolts. The mounting holes are opened on the floor slab 1 and waterproofed to prevent moisture from entering the floor slab 1, thereby extending the service life.

[0044] In some embodiments of the present invention, multiple bracket structures 3 and connecting structures are provided. The bracket structures 3 are spaced apart in the vertical direction and are distributed between each floor slab 1. The connecting structures are distributed in a matrix.

[0045] Specifically, by vertically spaced multiple bracket structures 3 and arranging the connecting structures in a matrix, the self-weight load and external force load of the decorative wall can be evenly distributed to the bracket structures 3 and the base wall 2 on each floor, avoiding localized stress concentration and deformation caused by concentrated loads. Simultaneously, the matrix arrangement makes the stress system of the decorative wall more continuous, improving the overall bending, shear, and torsional stiffness, making it particularly suitable for the facade systems of high-rise or super high-rise buildings. Furthermore, this layout offers high flexibility, allowing for optimized design based on different building facade shapes and dimensions, enhancing its applicability and engineering application value.

[0046] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
