Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building thermal insulation, in particular to a building exterior wall with a thermal bridge breaking structure. Background Art
[0002] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the utility model, and shall not necessarily be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to ordinary technicians in this field.
[0003] The insulation of the building's exterior walls is an important part of building energy conservation, and at the same time, the building's exterior walls are also an important part of building fire prevention. In the prior art, fire prevention is usually achieved by nailing the inner and outer fireproof panels to the keel frame. However, this nailing method will form a metal through-type thermal bridge from the self-tapping screw to the steel keel and then to the self-tapping screw; and the keel is mostly made of square steel pipes, rectangular tubes and other hollow profiles with closed inner cavities. Compared with the high-efficiency thermal insulation materials in the keel cavity, the difference in thermal conductivity between the two is very large, which is not conducive to uniform heat transfer on the wall panel surface. Therefore, the thermal insulation performance of the building's exterior walls in the prior art is poor. At the same time, the wall panels of the building's exterior walls only use the keel as the load-bearing skeleton, and the inner fireproof panels are only used for covering, and the strength is not high. The heavy objects on the indoor side can only be fixed at the keel position, which is not conducive to interior decoration. Utility Model Content
