Description

Technical Field

[0001] This utility model relates to the field of aluminum honeycomb panel technology, and specifically to an edge sealing structure for an aluminum honeycomb composite panel. Background Technology

[0002] Aluminum honeycomb panels are suitable for civil buildings, vehicle and ship decoration, etc. They represent the application of aerospace materials in civil construction. The entire processing is completed in a modern factory using hot-pressing technology. Due to the high thermal conductivity between the aluminum skin and the honeycomb structure, the thermal expansion and contraction of the inner and outer aluminum skins are synchronized. Small holes in the honeycomb aluminum skin allow for free air flow within the panel. The sliding mounting system prevents structural deformation during thermal expansion and contraction.

[0003] The edge banding of aluminum honeycomb panels has the problem of incomplete coverage at the edge joints. Traditional edge banding processes are achieved by sandwiching cores, but gaps will remain at the joints after the edge banding is completed. After long-term use, rainwater will seep into the gaps, affecting the performance and reducing the service life.

[0004] Therefore, we propose an edge sealing structure for aluminum honeycomb composite panels. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides an edge sealing structure for an aluminum honeycomb composite panel. By providing clamping strips around the entire aluminum honeycomb panel body, the panel body can be fully protected. Grooves are provided in the clamping strips to fit the protrusions of the edge sealing, increasing the contact area between the two and improving the connection effect, making the connection more stable. By providing a stepped layer, the contact area between the clamping strips and the edge sealing can be further increased. At the same time, the gaps on both sides of the clamping strips and the edge sealing can be changed from outer gaps to inner gaps, further preventing rainwater erosion.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] An edge sealing structure for an aluminum honeycomb composite panel is characterized by comprising an aluminum honeycomb panel body, strips bonded to all four sides of the aluminum honeycomb panel, a protective plate attached to each of the upper and lower ends of the aluminum honeycomb panel, a strip bonded to each side wall, and an edge seal attached to the outer side of each strip.

[0010] Preferably, each of the clamping strips has chamfered corners at both ends, and the chamfers of adjacent clamping strips can be joined together to form a complete corner.

[0011] Preferably, both ends of the edge banding are also chamfered to allow the beginning and end of adjacent edge bandings to fit together.

[0012] Preferably, each of the clamping strips has a groove in the middle, the groove has an isosceles trapezoidal cross-section, and a protrusion that matches the groove is formed on one side of the sealing edge, the protrusion and the groove fitting together.

[0013] Preferably, stepped layers are formed on both sides of the protrusion, and stepped layers that fit together are also formed on both sides of the groove.

[0014] (III) Beneficial Effects

[0015] This utility model embodiment provides an edge sealing structure for an aluminum honeycomb composite panel. It has the following beneficial effects:

[0016] 1. By setting clips around the entire aluminum honeycomb panel body, the aluminum honeycomb panel body can be fully protected. The clips have grooves to fit the protrusions of the edge sealing, increasing the contact area between the two, improving the connection effect, and making the connection more stable.

[0017] 2. By setting a stepped layer, the contact area between the strip and the edge banding can be further increased. At the same time, the gaps connecting the two sides of the strip and the edge banding in the bonded state can be changed from the outer gaps to the inner gaps, further preventing rainwater erosion.
