NOVELTY - The system has an aluminum alloy upright post (1) installed in a middle of an aluminium alloy supporting hidden frame cross beam angle code (4). A hot galvanizing steel square pipe (2) is detachably installed inside the aluminum alloy vertical post. A mounting block (13) detachably mounted on an outer side of the hot galvanized steel square tube. An aluminum alloy pressing plate (16) detachable installed outside the mounting block. A glass (3) is mounted between the mounting blocks and the aluminum steel pressing plate. A locking mechanism for locating the hot-graphene steel square tubes (2), is provided inside the aluminium alloy vertical column. The locking mechanism is provided with a square tube positioning rod (21) rotatably connected to inside of the aluminum aluminum vertical column, and the square pipe positioning rod is close to the outside of the heat-insulated steel square pipes. USE - Rear-mounted aluminum alloy steel sleeve core composite glass curtain wall upright post system for use in a building. ADVANTAGE - The aluminum alloy upright post and the hot galvanizing steel square pipe are separated design, when mounting, so as to improve the application range of hot galvanized steel square tube. The square tube locating rod is rotatably connected in the aluminum alloy post, so that the rubber pad is propped against the side wall of the square tube, realizing the application of rubber pad against the hot square pipe, when the top of hot square tube contacts with the bottom of the locating rod, thus improving the performance of the system. The system is easy to install, and can be manufactured at low cost, and has high durability.
