The invention provides an externally-mounted prefabricated sandwich type thermal-insulation concrete wallboard and an assembling system and construction method thereof. The technical problem that a connecting structure between vane boards on the two sides of an existing thermal-insulation wallboard is insufficient in strength is solved by enabling steel bar truss web bars in a continuously-bent status to be connected to longitudinal reinforcing bars on an inner vane board and an outer vane board of the thermal-insulation wallboard. In addition, the externally-mounted wallboard is in assembling connection with a steel beam and a floorslab through a pre-buried bolt technical means or a split bolt technical means. Meanwhile, the self-characteristics of a steel structure are considered, and the assembly structure strength between the wallboard and the steel beam as well as between the wallboard and the floorslab is guaranteed.
Description
technical field [0001] The present invention relates to the technical field of prefabricated concrete sandwich thermal insulation wall panels, in particular to an externally-mounted prefabricated concrete sandwich thermal insulation wall panel structure, a wall panel assembly system, and a construction method. Background technique [0002] At present, the most mature prefabricated enclosure walls suitable for steel structure buildings are curtain wall systems and autoclaved aerated concrete prefabricated slat walls. Among them, prefabricated concrete sandwich insulation wall panels are widely used in concrete structure buildings and are an assembly technology for enclosure walls with great development potential. However, considering the many performance differences between steel structures and concrete structures, when considering different materials Under the premise of "compatibility" issues, it is difficult to directly apply the relevant connection structures for concrete...
