The invention discloses a construction structure of exterior facade black
brick decoration and a construction method, and belongs to the technical field of building decoration construction. The construction structure comprises a steel plate, steel channels, a first rectangular steel
pipe, a second rectangular steel
pipe, first square pipes and second square pipes, wherein the inner side of the steel plate is fixedly installed on an exterior facade of an original building, the first rectangular steel
pipe is vertically and fixedly installed on the outer side of the steel plate, the second rectangular steel pipe is arranged on the outer side of the first rectangular steel pipe, the second rectangular steel pipe is fixedly connected with the first rectangular steel pipe through a plurality offirst square pipes and second square pipes to form a
brick curtain wall supporting system, and the steel plate is fixedly connected with the
brick curtain wall supporting system through the pluralityof steel channels. According to the construction structure and the construction method, the structure is simple, the size is small, manual carrying and assembling are facilitated, construction is convenient, and the construction period is shortened; component
prefabrication production and
assembly type construction are adopted, the
standardization degree is high, and great popularization in a construction site in the future is facilitated; and the construction method is economical, reasonable, energy-saving, environment-friendly and beneficial to
cost control and resource environment protection.
