The existing energy-saving doors and windows are all formed by heat-insulating bridge-cut-off aluminum alloy sections, and in order to meet the requirements of heat insulation, sound insulation and door and window three properties, the following two methods are generally adopted: 1. the two sides of the heat insulation plate are made of aluminum alloy materials (generally 6063-T5), and the middle of the heat insulation plate is connected with a heat insulation penetrating strip (PA + 25% GF) through rolling clamping; 2. an aluminum alloy material (generally 6063-T5) is used, an elastomer (non-foamed PU polyurethane) is poured into the middle cavity, and then the connecting part in the middle of the aluminum alloy material is disconnected. Although the heat insulation bridge-cut-off aluminum alloy sections have greatly improved heat insulation and energy saving effects, the two heat insulation bridge-cut-off aluminum alloy sections have the following two disadvantages in actual use: firstly, expansion and contraction reactions can be generated due to the change of the environmental temperature and humidity, so that a gap can be generated at the joint of the aluminum alloy material and the heat insulation penetrating strip, the mechanical connection strength of the section bar is reduced, and the phenomena of water seepage and air permeability are easy to occur; secondly, the metal occupation ratio of the section bar is high, and the weight of the section bar is heavy. Aiming at the higher and higher requirements of users and the promotion of national environmental protection and energy saving policies, particularly the requirements of energy-saving buildings and houses, the existing heat-insulating bridge-cutoff aluminum alloy section bar cannot meet the requirements.
