Description

Technical Field

[0001] This utility model relates to the field of building materials technology, specifically to a double-layer composite aluminum corrugated sheet. Background Technology

[0002] Aluminum corrugated sheet is a building material made from aluminum alloy as the base material and processed using special techniques. It possesses many excellent properties and is widely used in construction, decoration, packaging, and other fields. Compared to traditional building materials such as steel, aluminum corrugated sheet is lighter in weight but maintains sufficient strength, ensuring adequate load-bearing capacity. It also has good corrosion resistance; a dense oxide film naturally forms on the aluminum alloy surface, effectively preventing further corrosion.

[0003] When installing aluminum corrugated panels, the keel is first fixed, and then the panels are fixed to the keel. Fasteners such as rivets or bolts are used at the joints. However, in actual use, the rigidly connected aluminum corrugated panels will bear the load from the keel and other components, resulting in noise and stress transmission at the joints. In addition, the aluminum corrugated panels themselves are multi-layer aluminum alloy structures with rigid connections. Long-term stress can also cause the joints to loosen, affecting the structural strength. There is room for technical improvement. Utility Model Content

[0004] This invention aims to solve the aforementioned technical problems, namely, that rigidly connected aluminum corrugated sheets bear loads from components such as keels during use, and that the rigid connection of the multi-layer aluminum alloy structure can lead to loosening of the joints under prolonged stress. The invention provides a double-layer composite aluminum corrugated sheet.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a double-layer composite aluminum corrugated sheet, comprising a sheet body and a mounting frame; the sheet body is detachably installed on the bottom surface of the mounting frame; the sheet body comprises, from top to bottom, a surface layer, a first corrugated layer, a reinforcing layer, a second corrugated layer, and a bottom layer, wherein the first corrugated layer and the second corrugated layer are oriented in opposite directions, and aerogel is filled between them and the reinforcing layer; several buffer strips are provided on the side of the first corrugated layer and the second corrugated layer away from the reinforcing layer; and further comprising: A connecting structure is located between the plate and the mounting frame, including several connectors evenly installed on the bottom surface of the mounting frame. A buffer pad is provided under the connector, and a second U-shaped connector is detachably provided on the outside of the buffer pad. The second connector is connected to the plate by bolts.

[0006] Furthermore, each end of the mounting frame is provided with a through hole, and a crossbar is passed through the through holes, with the crossbar slidably connected to each mounting frame.

[0007] Furthermore, the buffer strips are located between the first corrugated layer and the surface layer, and between the second corrugated layer and the bottom layer, respectively; the buffer strips are made of rock wool.

[0008] Furthermore, the connector has an I-shaped cross-section, and both the front and rear ends of the connector are provided with mounting plates, which are fixed to the corresponding positions of the mounting frame by the mounting plates and bolts.

[0009] Furthermore, both the connector and the second connector are made of metal; the buffer pad is made of composite rubber.

[0010] Furthermore, both the buffer pad and the second connector are provided with through mounting holes and are connected through the mounting holes.

[0011] The advantages of this utility model compared with the prior art are as follows: It features a double-layer corrugated structure to ensure structural strength; buffer strips are installed between the double-layer corrugations and the corresponding panels and base plates to reduce force transmission, making it less likely to reduce structural strength due to load, and also reducing noise transmission. When connecting to the mounting frame, a buffer pad is provided to reduce the transmission of load and noise between the mounting frame and the plate, and to avoid affecting the structural strength of the plate.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings.

[0018] Example 1, in conjunction with Appendix Figure 1A double-layer composite aluminum corrugated sheet includes a sheet body 1 and a mounting frame 2. Each end of the mounting frame 2 has through holes, and a crossbar 3 passes through these through holes. The crossbar 3 is slidably connected to each mounting frame 2. The crossbar 3 supports multiple mounting frames 2, improving their stability. During actual installation, the mounting frames 2 are inserted through the through holes onto the crossbar 3, and subsequently, a fixing plate 1 limits the mounting frames 2 on the crossbar 3. Fixing plates are provided at both ends of the crossbar 3, and the crossbar 3 is anchored to the wall through these fixing plates to achieve stable support for the mounting frames 2. Combined with appendix Figure 1 , 2 4. The panel 1 is detachably installed on the bottom surface of the mounting frame 2. The panel 1 consists of a top layer 4, a first corrugated layer 5, a reinforcing layer 6, a second corrugated layer 7, and a bottom layer 8 from top to bottom. The first corrugated layer 5 and the second corrugated layer 7 are oriented in opposite directions, and aerogel is filled between them and the reinforcing layer 6. The aerogel can reduce the overall thermal conductivity of the panel 1, block some heat conduction, and improve the thermal insulation of the panel 1. The top layer 4 and the bottom layer 8 are both made of aluminum. Aluminum has low sealing, is lightweight, corrosion-resistant, fire-retardant, environmentally friendly, and recyclable. The first corrugated layer 5 and the second corrugated layer 7 enhance the compressive and bending resistance of the top layer 4 and the bottom layer 8 through the corrugated structure. The double corrugation further improves the overall structural strength. The reinforcing layer 6 is used to increase the contact area between the double corrugations, playing a role in auxiliary support and reinforcement. Based on the above structure, several buffer strips 9 are provided on the side of the first corrugated layer 5 and the second corrugated layer 7 away from the reinforcing layer 6; the buffer strips 9 are located between the first corrugated layer 5 and the surface layer 4, and between the second corrugated layer 7 and the bottom layer 8; the buffer strips 9 are made of rock wool, and the rock wool fibers have good flexibility and elasticity, and can undergo a certain deformation when subjected to external force, thereby absorbing and dispersing impact energy, playing a buffering role, and ensuring the structural strength of the board 1; the buffer strips 9 are fixed to the first corrugated layer 5 and the second corrugated layer 7 by adhesive; Combined with appendix Figure 1 , 2 3. It also includes a connecting structure located between the plate 1 and the mounting frame 2; including a number of connectors 10 evenly installed on the bottom surface of the mounting frame 2. The cross-section of the connector 10 is I-shaped, which facilitates the installation of the buffer pad 12 mentioned below and increases the contact area between it and the buffer pad 12; the front and rear ends of the connector 10 are provided with mounting plates 11, and are fixed to the corresponding positions of the mounting frame 2 by the mounting plates 11 and bolts. Based on the above structure, a buffer pad 12 is also provided below the connector 10. The buffer pad 12 is made of composite rubber material, which can deform and absorb energy when subjected to force, thus playing a buffering role. A U-shaped connector 2 13 is detachably provided on the outside of the buffer pad 12. Specifically, both the buffer pad 12 and the connector 2 13 are provided with through mounting holes, and are connected through the mounting holes to realize the fixed installation of the connector 2 13. The connector 2 13 is connected to the plate 1 by bolts. Both the connector and the connector 2 are made of metal to ensure structural strength and prevent deformation during long-term use.
