Abstract
Description
Technical Field
[0001] This utility model belongs to the field of composite panel exterior wall technology, and particularly relates to an aluminum-plastic composite panel exterior wall structure system. Background Technology
[0002] Aluminum-plastic composite panels, as a new type of decorative material, were introduced to China from Germany in the late 1980s and early 1990s. They quickly gained popularity due to their economy, diverse color options, convenient construction methods, excellent processing performance, superior fire resistance, and high quality. They can be used for building exteriors, curtain wall panels, renovation of old buildings, interior wall and ceiling decoration, advertising signs, display stands, and cleanroom dust control projects. While a new type of building decoration material, existing aluminum-plastic composite panel materials cannot effectively provide fire resistance. Therefore, an aluminum-plastic composite panel exterior wall structure system has been proposed.
[0003] For example, Chinese patent CN202556833U discloses a weather-resistant aluminum-plastic composite panel. Its main purpose is to address the problems of cracking, fading, and discoloration of the fluorocarbon coating in aluminum-plastic composite panels used for building exteriors. A PVDF film is applied to the upper surface of the base aluminum-plastic composite panel. With this structure, the PVDF film layer effectively protects the underlying fluorocarbon coating, improving the service life of the aluminum-plastic composite panel.
[0004] The aforementioned patent has the following problems:
[0005] Compared to existing aluminum-plastic composite panels, which are not effectively fireproof and pose a safety hazard over long-term use, thus reducing their lifespan and increasing manufacturing costs, current aluminum-plastic composite panels also lack proper sealing, resulting in gaps and air leaks that affect their normal operation. Therefore, we propose an aluminum-plastic composite panel exterior wall structure system. Utility Model Content
[0006] The purpose of this utility model is to address the aforementioned technical problems by providing an aluminum-plastic composite panel exterior wall structure system that achieves the effects of fire resistance and good sealing of the aluminum-plastic composite panel.
[0007] In view of this, the present invention provides an aluminum-plastic composite panel exterior wall structure system, including a composite aluminum panel, and further comprising: a galvanized steel pipe movably installed on one side of the composite aluminum panel, a galvanized steel plate being installed through the interior of the galvanized steel pipe, fireproof cotton being fixedly installed inside the galvanized steel plate, gunpowder nails being movably installed on one side of the galvanized steel plate, sealant being fixedly installed on the top of the composite aluminum panel, a galvanized angle bracket being fixedly installed at the bottom of the sealant, a galvanized square gasket being fixedly installed on the surface of the galvanized angle bracket, and a stainless steel bolt being installed through the interior of the galvanized square gasket.
[0008] Based on the above structure, multiple composite aluminum panels are spliced together for easy assembly and then used to support the exterior wall. Galvanized steel plates are then fixed to one side of the composite aluminum panels to enhance their stability. The galvanized steel plates are secured with gunpowder nails. Fireproof cotton is then placed inside the galvanized steel plates to provide fire protection and enhance the fire resistance of the composite aluminum panels. The fireproof cotton uses inorganic fiber cotton, which further enhances its fire-resistant properties. When used in conjunction with the composite aluminum panels, the inorganic fiber cotton effectively improves the fireproofing effect, ensuring long-term safety and increasing the overall fire resistance of the composite aluminum panels. To extend the service life and reduce the cost of manufacturing composite aluminum panels, stainless steel bolts are used to fix galvanized square gaskets to the surface of the composite aluminum panel. Galvanized angle brackets provide a high-strength and corrosion-resistant connection, strengthening the work of the galvanized square gaskets. With the addition of sealant, the gaps between the galvanized angle brackets, galvanized square gaskets and the composite aluminum panel can be sealed. It can also be used to seal other gaps. When used together, the composite aluminum panel can perform a sealing function, and the sealing performance can meet the requirements during installation, without gaps or air leakage, without affecting the normal operation of the composite aluminum panel.
[0009] Preferably, a second steel pipe is movably mounted on the top of the sealant, and a galvanized steel sleeve is movably provided on the top of the second steel pipe. The second steel pipe is used to support the composite aluminum plate.
[0010] Preferably, a second steel pipe is movably mounted on the top of the sealant, and a galvanized steel sleeve is movably provided on the top of the second steel pipe.
[0011] Preferably, a first reinforcing rib is fixedly provided inside the composite aluminum plate, and a second reinforcing rib is fixedly installed on the other side of the first reinforcing rib. The first reinforcing rib facilitates the reinforcement of the composite aluminum plate material.
[0012] Preferably, a pre-embedded part is fixedly installed on one side of the galvanized angle bracket, which facilitates the fixing of the composite aluminum plate.
[0013] Preferably, a filling layer is fixedly provided on both sides of the first reinforcing rib. The filling layer is made of latex material, which facilitates the enhancement of the internal performance of the composite aluminum plate.
[0014] The beneficial effects of this utility model are:

The fireproof cotton, made of inorganic fiber, enhances the fire resistance of the composite aluminum panels. When used in conjunction with the inorganic fiber cotton, the composite aluminum panels effectively improve the fireproofing effect, ensuring long-term safety and increasing the lifespan of the composite aluminum panels while reducing manufacturing costs.
[0016] 2. This aluminum-plastic composite panel exterior wall structure system utilizes stainless steel bolts to fix galvanized square gaskets to the surface of the composite aluminum panel. Galvanized angle brackets then provide a high-strength and corrosion-resistant connection, reinforcing the function of the galvanized square gaskets.
