Connecting joint of composite outer walls and composite beam and construction method of connecting joint

Abstract

Disclosed are a connecting joint of composite outer walls and a composite beam and a construction method of the connecting joint. The connecting joint comprises the first composite outer wall (A) andthe second composite outer wall (B) which are arranged in a composite mode through a connecting area (14). The first composite outer wall (A) and the second composite outer wall (B) are connected withthe composite beam (C) through the connecting area. Vertical connecting steel bars (9) are pre-embedded in composite wall cast-in-place layers (5) of the first composite outer wall and the second composite outer wall and the connecting area (14). The first composite outer wall and the second composite outer wall are internally provided with reinforcing steel bar hoops perpendicular to the vertical connecting steel bars. The vertical connecting steel bars are arranged in the reinforcing steel bar hoops or bound or welded to the reinforcing steel bar hoops. Wall vertical steel bars (3) in an outer leaf wall plate (10) and an inner leaf wall plate (2) of the second composite outer wall located at the lower part extend into the connecting area (14). Beam transverse steel bars (15) in a beam prefabricated layer (7) and a beam cast-in-place layer (6) extend into the connecting area, and cast-in-place concrete in the connecting area makes the first composite outer wall and the second composite outer wall be connected with the composite beam into a whole.

Description

Technical field [0001] The invention belongs to the technical field of construction engineering, and specifically relates to a connection node of a laminated external wall and a laminated beam and a construction method thereof. Background technique [0002] Prefabricated buildings are widely recognized and promoted for their outstanding advantages such as standard, high efficiency, heat preservation, energy saving and environmental protection. However, some prefabricated components in prefabricated buildings, such as prefabricated laminated walls, are layered products, including prefabricated outer blades, intermediate cast-in-place layers and prefabricated inner blades, or including prefabricated thermal insulation external wall panels, thermal insulation material panels, and prefabricated external panels. Blades, middle cast-in-situ layer and prefabricated inner blades. The multi-layer structure of this prefabricated laminated wall easily causes low internal connection structur...

However, some prefabricated components in prefabricated buildings, such as prefabricated laminated walls, are layered products, including prefabricated outer leaves, intermediate cast-in-place layers and prefabricated inner leaves, or prefabricated thermal insulation external wall panels, thermal insulation material panels, prefabricated external Leaf plate, middle cast-in-place layer and prefabricated inner leaf plate, the multi-layer structure of the prefabricated laminated wall is likely to cause low strength and poor integrity of the internal connection structure, especially the prefabricated outer leaf plate, middle cast-in-place layer and prefabricated inner leaf The bonding force of the board needs to be further strengthened

In addition, the connection strength and integrity between prefabricated composite walls and composite beams need to be further strengthened
