A kind of cast-in-place thermal insulation shear wall, column and beam

Abstract

The invention discloses a cast-in-place heat preserving shear wall, column and beam, which comprises a heat preserving and insulating plate (4), steel bars (6) and a cast-in-place concrete layer (10), wherein holes (5) are formed on the heat preserving and insulating plate (4); and heat insulating pieces (1) formed by heat insulating blocks (2) and reinforcing bars (3) transversely inserted into the heat insulating blocks (2) are arranged in the holes (5) on the heat preserving and insulation plate (4). The heat preserving and insulating plate (4) is fixed by locating pieces (7) through tying pieces (9), and cold bridges produced due to the connection of concrete on the two sides of the heat preserving and insulating plate (4) are cut off by the heat insulating pieces (1) arranged in the holes (5) on the heat preserving and insulating plate (4). The steel bar concrete on the two sides of the heat preserving and insulating plate (4) in the cast-in-place heat preserving shear wall, column and beam can act synergistically and bear force jointly, the construction of the cast-in-place heat preserving shear wall, column and beam is simple, the construction quality is easy to guarantee, and obtained members have great heat preserving effects. The method of arranging the heat insulating pieces (1) in the holes on the heat preserving and insulating plate can also be applied to the cast-in-place roof system.

Description

Technical field: [0001] The invention relates to the field of construction, in particular to a cast-in-place thermal insulation shear wall, column and beam for construction. Background technique: [0002] Building thermal insulation mainly takes measures from the building's external enclosure structure, and at the same time reduces the indoor heat of the building from being emitted to the outside. Building thermal insulation plays an important role in creating a suitable indoor thermal environment and saving energy. The shear wall structure has high rigidity, good integrity and seismic performance, and is widely used in high-rise buildings. Since the shear wall is constructed with cast-in-place concrete, it is generally necessary to take corresponding insulation measures. At the same time, due to the strong heat transfer capacity of the reinforced concrete columns and beams around the outer wall, it is the position where the cold and heat bridge effect is prone to occur in t...

AI Technical Summary

Problems solved by technology

This kind of building insulation method is simple and easy to implement, but because the space of the hole through which the reinforcement is filled is filled with concrete, a cold bridge is easily formed in this part of the shear wall, column, and beam, and condensation occurs, which makes the building insulation effect discount
