Prefabricated concrete externally-hung wallboard system and construction method thereof

Abstract

The invention discloses a prefabricated concrete externally-hung wallboard system and a construction method thereof. The prefabricated concrete externally-hung wallboard system comprises a concrete externally-hung wallboard, upper hanging assemblies and lower hanging assemblies, the upper hanging components are connected between the upper part of the concrete externally-hung wallboard and a main body structure at intervals, and comprise first hanging plates, vertical buried plates, first vertical reinforcing steel bars, horizontal buried plates and horizontal reinforcing steel bars, the first hanging plates are buried in the upper portion of the concrete externally-hung wallboard, the upper ends of the first hanging plates exceed the top face of the concrete externally-hung wallboard, U-shaped grooves are formed in the middles of the tops of the first hanging plates, the lower hanging components are buried at the lower part of the concrete externally-hung wallboard at intervals and comprise second hanging plates, first clamping plates, second clamping plates, second vertical reinforcing steel bars and connecting bolts, the first clamping plate and the second clamping plate o the upper layer are clamped on two sides of the first hanging plate on the lower layer, and the connecting bolt on the upper layer is clamped in the U-shaped groove on the lower layer. According to the prefabricated concrete externally-hung wallboard system and the construction method, the technical problems that a connecting piece of a traditional externally-hung wallboard is difficult to position and prone to displacement, the thickness of a protection layer is difficult to control, a heat preservation layer is prone to floating, and shock resistance is poor are solved.

Description

technical field [0001] The invention belongs to the technical field of prefabricated building construction engineering, and in particular relates to a prefabricated concrete external wall panel system and a construction method thereof. Background technique [0002] Compared with the traditional brick wall structure, the prefabricated external wall panel has the characteristics of good integrity, light structure, increasing the effective use area of ​​the building, reducing on-site wet work, improving working conditions, and increasing labor productivity. One of the important ways to improve the level of building industrialization is to promote the standardization, industrial production and installation of building components. There are many problems in the existing prefabricated concrete sandwich insulation external wall panel connectors commonly used in China, such as anchoring mechanics problems, complex structure, difficult positioning of the connectors, easy displacement...
