Structure for connecting beams with wall plates and doors and windows of aluminum alloy house

The invention relates to a structure for connecting beams with wall plates and doors and windows of an aluminum alloy house. An aluminum alloy wall plate frame is independently manufactured. An aluminum alloy outer wall plate is combined with a C-shaped steel keel, a thermal insulation and fire-proof calcium silicate board and an indoor decoration board to form a unit type spliced wall plate. The aluminum alloy wall plate frame is fastened on an aluminum alloy beam through the unit type spliced wall plate by means of fastening pieces. Aluminum alloy auxiliary beam fixing aluminum corners are arranged on the head portions of aluminum alloy auxiliary beams. The aluminum alloy auxiliary beam fixing aluminum corners and the aluminum alloy auxiliary beams are fixed to the aluminum alloy beam together through fastening pieces. An aluminum alloy door and window auxiliary frame is connected with an aluminum alloy door or window frame through fastening pieces, wherein an aluminum alloy door or window sash is prefabricated on the aluminum alloy door or window frame. The structure is simple in structure and connection, short in construction cycle and convenient to install. Due to the fact that the outer wall plate contains thermal insulation and sound insulation rock wool and the thermal insulation and fire-proof calcium silicate board, the house has good thermal insulation and heat preservation performance, good sound insulation performance, good waterproof performance, good fireproof performance and other performance. A waterproof groove is formed in the aluminum alloy door and window auxiliary frame, and therefore the waterproof performance of the doors/windows is improved.
