Fabricated external wall system and construction method thereof

Abstract

The invention discloses a fabricated external wall system and further discloses a construction method for the fabricated external wall system. The fabricated external wall system comprises a laminatedbeam, a laminated slab, an upper prefabricated wall plate and a lower prefabricated wall plate, wherein the upper prefabricated wall plate and the lower prefabricated wall plate are assembled at theupper end and the lower end of the laminated beam correspondingly. A first heat insulating layer extending in the longitudinal section direction of the laminated beam is pre-embedded into the laminated beam. The laminated slab comprises a slab prefabricated layer and a slab cast-in-place layer. The slab prefabricated layer is in lap joint with the upper portion of the laminated beam. The slab cast-in-place layer is cast on the upper portion of the slab prefabricated layer, and a docking region is formed between the slab cast-in-place layer and the laminated beam. According to the fabricated external wall system, the first heat insulating layer is pre-embedded into the laminated beam, and the first heat insulating layer guarantees the heat insulating effect of the laminated beam; because the first heat insulating layer is pre-embedded into the laminated beam, there is no need to arrange an external wall plate provided with a heat insulating layer on the outer side of the beam in a hungmode; and the laminated beam can be directly assembled between the upper prefabricated wall plate and the lower prefabricated wall plate, connecting is achieved without an external member, and connecting is simple.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to an assembled exterior wall system and a construction method thereof. Background technique [0002] In the field of construction engineering technology, prefabricated buildings are becoming more and more popular. Traditional prefabricated exterior wall panels have built-in insulation layers, and prefabricated beams and prefabricated exterior wall panels are set separately. The exterior wall panels need to be hung on the outside of the prefabricated beams. [0003] The traditional exterior wall panels are equipped with hook seats, and the prefabricated beams are provided with sleeves. During assembly, the hook seats and sleeves are connected by connecting screws to assemble the exterior wall panels with insulation layers on the prefabricated beams. It is used during on-site construction. There are many components and the connection is cumbersome. Contents of the...
