Description

Technical Field

[0001] This utility model relates to the field of aluminum honeycomb panel technology, and in particular to a pre-embedded subframe aluminum honeycomb panel with high load-bearing capacity. Background Technology

[0002] Traditional aluminum honeycomb panels (such as those published in CN207345188U) achieve basic sealing and edge protection by setting inner sealing strips and edge sealing components at the connection between the honeycomb core and the aluminum plate, but their structural strength still has significant limitations.

[0003] Insufficient edge shear resistance: The inner seal is only connected to the groove through an adhesive layer. Under lateral loads (such as wind pressure or earthquakes), the adhesive is prone to failure, resulting in edge cracking or deformation.

[0004] Poor overall load-bearing capacity dispersion: The honeycomb core and aluminum plate are bonded together in a planar manner, lacking three-dimensional mechanical support. Under concentrated loads or dynamic impacts, local dents or honeycomb core collapses are likely to occur.

[0005] Low installation stability: The simple interlocking design of the edge banding and inner sealing strip cannot resist long-term vibration or temperature stress, which can easily cause the connection to loosen and affect the safety of the curtain wall or roof system. Utility Model Content

[0006] The purpose of this invention is to provide a high-load-bearing pre-embedded frame aluminum honeycomb panel. It not only utilizes the vertical intersection design of the vertical frames and trusses to form a spatial grid support structure, transforming the traditional planar stress pattern into a three-dimensional load-bearing system and improving bending stiffness; but also employs a mortise-and-tenon mechanical pre-connection between truss connecting blocks and truss connecting slots, and connecting bolts one and two respectively lock the vertical frames and trusses. This ensures no displacement of the connection nodes under dynamic loads, improves shear strength, and achieves multi-point force transmission, avoiding stress concentration caused by single-bolt connections. Furthermore, by adding reinforcing girders between the vertical frames to form transverse reinforcing ribs, the mid-span bending moment is effectively dispersed, thereby greatly improving the load-bearing capacity of the aluminum honeycomb panel of this invention.

[0034] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0035] Please refer to Figures 1 to 7 As shown, an embodiment of this utility model provides a high-load-bearing pre-embedded subframe aluminum honeycomb panel, comprising: two pre-embedded subframe vertical frames 1, the two pre-embedded subframe vertical frames 1 being connected by two symmetrically arranged pre-embedded subframe trusses 2, the pre-embedded subframe trusses 2 and the pre-embedded subframe vertical frames 1 being detachable, and the pre-embedded subframe vertical frames 1 and the pre-embedded subframe trusses 2 being fixedly connected by a reinforcing connection component 3, a reinforcing waist beam 4 being provided between the two pre-embedded subframe vertical frames 1, and an aluminum honeycomb panel body 5 being provided between the reinforcing waist beam 4 and the pre-embedded subframe trusses 2;

[0036] By adopting the above technical solution, not only is a spatial grid support structure formed by the vertical intersection design of the vertical frame and the truss, transforming the traditional planar force-bearing mode into a three-dimensional load-bearing system and improving bending stiffness; but also the use of mortise and tenon mechanical pre-connection between the truss connecting block 201 and the truss connecting groove 2011, and the locking of the vertical frame and the truss by connecting bolt 1 302 and connecting bolt 2 303 respectively, which ensures no displacement of the connection node under dynamic load, improves shear strength, and realizes multi-point force transmission, avoiding stress concentration caused by single bolt connection; and by adding a reinforcing waist beam 4 between the vertical frames to form a transverse reinforcing rib, the mid-span bending moment is effectively dispersed, thereby greatly improving the load-bearing capacity of the aluminum honeycomb panel of this utility model.

[0037] To achieve precise pre-connection and high-strength assembly of the pre-embedded subframe truss 2 and the pre-embedded subframe vertical frame 1, in this embodiment: both sides of the pre-embedded subframe truss 2 are provided with truss connecting blocks 201 that are pre-connected to the pre-embedded subframe vertical frame 1, and the pre-embedded subframe vertical frame 1 is provided with truss connecting grooves 2011 that match the truss connecting blocks 201. Through the mortise and tenon mechanical pre-connection design, the two are ensured to be accurately positioned before installation, reducing on-site adjustment time. At the same time, the pre-connection structure can withstand part of the load, reducing the risk of deformation during installation and improving the shear resistance of the overall structure.

[0038] To enhance the connection stability and fatigue resistance of the embedded subframe vertical frame 1 and the embedded subframe truss 2, in this embodiment: the reinforcing connection component 3 includes an L-shaped connector 301 for connecting the embedded subframe vertical frame 1 and the embedded subframe truss 2. One side of the L-shaped connector 301 abuts against the side of the embedded subframe vertical frame 1, and the other side of the L-shaped connector 301 abuts against the embedded subframe truss 2. A connecting bolt 302 is provided on one side of the L-shaped connector 301, and a connecting bolt 302 is provided on the other side of the L-shaped connector 301.

The reinforcing connection component 3 adopts L-shaped connector 301, which is fixed to the side of the vertical frame and truss by connecting bolt 1 302 and connecting bolt 2 303 respectively, forming a double bolt locking structure, effectively dispersing the stress at the connection point and avoiding the risk of loosening or breakage caused by single bolt connection.

[0039] To optimize the ease of installation and structural compactness of the L-shaped connector 301, in this embodiment: the pre-embedded subframe vertical frame 1 and the pre-embedded subframe truss 2 are each provided with a receiving groove 3011 that matches the L-shaped connector 301 at the corresponding positions of the L-shaped connector 301. The pre-embedded subframe vertical frame 1 and the pre-embedded subframe truss 2 are provided with receiving grooves 3011 at the corresponding positions of the L-shaped connector 301, so that the connector is completely embedded in the frame, reducing the thickness of the panel edge, facilitating the sealing treatment of the curtain wall or roof system, and avoiding the risk of collision caused by exposed connectors, thus improving construction safety.

[0040] To enhance the connection strength and mid-span bending resistance between the reinforcing lumbar beam 4 and the embedded subframe vertical frame 1, in this embodiment: lumbar beam connecting blocks 401 are fixedly connected to both sides of the reinforcing lumbar beam 4; the side of the embedded subframe vertical frame 1, corresponding to the position of the lumbar beam connecting block 401, is provided with a lumbar beam connecting groove 4011 that matches the lumbar beam connecting block 401; the aluminum honeycomb panel 5 is fixedly installed on the embedded subframe vertical frame 1, the embedded subframe truss 2, and the reinforcing lumbar beam 4 using structural adhesive; the mortise and tenon joint connection enables rapid positioning and high-strength assembly of the lumbar beam and the vertical frame, effectively dispersing the mid-span bending moment and reducing the deflection of the plate; at the same time, the concealed design of the lumbar beam connecting groove 4011 avoids stress concentration and extends the structural life.

[0041] To achieve lightweight, high strength, and integrated load-bearing capacity of the aluminum honeycomb panel 5, in this embodiment: the aluminum honeycomb panel 5 is composed of upper and lower aluminum alloy panels and a middle honeycomb aluminum core, and the honeycomb of the honeycomb aluminum core is hexagonal. The hexagonal honeycomb structure disperses stress through a layered energy dissipation mechanism, effectively improving the load-bearing capacity under the same weight. At the same time, it is integrated with the pre-embedded sub-frame vertical frame 1, pre-embedded sub-frame truss 2, and reinforcing waist beam 4 through structural adhesive to form a spatial grid support system, further improving the overall bending stiffness and impact resistance.

[0042] The working principle of this utility model is as follows:

[0043] Pre-connection and mechanical fixation: The pre-connection design of truss connecting block 201 and truss connecting groove 2011 enables rapid positioning, and the L-shaped connector 301 and double bolt fixation ensure connection strength, forming a three-dimensional mechanical support.

[0044] Multi-level reinforcement structure: The reinforcing lumbar beam 4 is connected to the vertical frame through the lumbar beam connecting block 401 to form a transverse reinforcing rib, which effectively disperses the mid-span load and reduces deflection.

[0045] Integrated load-bearing system: The aluminum honeycomb panel 5 is tightly bonded to the pre-embedded subframe through structural adhesive. The hexagonal structure of the honeycomb core disperses stress, and the grid design of the frame transfers load, achieving a balance between lightweight and high strength.
