Description

Technical Field

[0001] This invention relates to the field of building structure system technology, and more specifically, to an exterior wall unit, an exterior wall body, and a building. Background Technology

[0002] Building walls, including interior and exterior walls, not only need to provide structural support, but also need to have good thermal insulation, fire resistance, and sound insulation. For exterior walls, sun protection and fire resistance are also usually required.

[0003] Since the interior is a relatively enclosed space where people live and work for extended periods, thermal insulation is a crucial requirement for buildings. Specifically, this means maintaining an indoor temperature higher than the outdoor temperature when temperatures are low, and a lower indoor temperature than the outdoor temperature when temperatures are high. The purpose of insulation is to keep the indoor temperature relatively stable, creating comfortable temperature conditions for people's lives and work. Existing building walls have poor thermal insulation performance, especially exterior walls, which are the main structural components affecting indoor temperature. Therefore, improving the thermal insulation performance of exterior walls is a pressing technical problem that needs to be solved in this field.

[0004] The existing building exterior walls are constructed on-site, which is not only inefficient but also results in inconsistent quality. The quality is determined by the construction workers, and there are many uncertainties in the construction effect. Moreover, it is difficult to guarantee the flatness of the walls.

[0005] In order to meet people's requirements for the quality and efficiency of wall construction, there is an urgent need to provide an exterior wall construction solution that is stable in quality, has good thermal insulation effect, and high construction efficiency. Summary of the Invention

[0025] In the above embodiments, the upper and lower keels, composite wall panels, and inner lining panels of the exterior wall unit can all be prefabricated in the factory. During construction, each part can be assembled on-site, which facilitates transportation, improves the construction efficiency of the exterior wall, and makes construction quick and convenient. Moreover, the prefabricated composite wall panels and inner lining panels have good flatness.
