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

Abstract

The invention discloses a cast-in-situ heat-insulating beam, column and shear wall which comprises a heat-insulating board, an inside cast-in-situ concrete layer and an outside cast-in-place concrete layer or mortar layer, wherein the heat-insulating board is provided with a hole, a hole reinforcer is arranged at the hole, a heat-insulating block is arranged in the hole reinforcer, reinforcing ribs are inserted in the heat-insulating block in a passing mode, and the reinforcing ribs are arranged in a full-length or middle cutting layout mode. The construction method comprises the following steps of: binding reinforcing cages, installing the heat-insulating board and a bar-mat reinforcement, arranging the hole reinforcer and the heat-insulating block, and erecting inside and outside templates; pouring outside concrete or mortar firstly, and then pouring inside concrete after the outside cast-in-place concrete layer or mortar layer achieves a certain strength; and after the inside cast-in-situ concrete layer and the outside cast-in-place concrete layer or mortar layer achieve a template removal strength, removing the inside and outside templates, thereby forming an integral cast-in-situ heat-insulating beam, column and shear wall. The cast-in-situ heat-insulating beam, column and shear wall is good in mechanical performance, simple in construction, and good in heat-insulating effect.

Description

Technical field: [0001] The invention relates to the field of construction, in particular to a cast-in-place thermal insulation beam, column, shear wall and construction method 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 i...

Problems solved by technology

However, the thermal insulation panels used in the cast-in-place thermal insulation beams, columns, and shear walls have holes, and the existence of holes weakens the strength of the thermal insulation panels, making it difficult for the thermal insulation panels to resist The thermal insulation board is easily damaged due to the side pressure generated, and it is difficult to effectively guarantee the thermal insulation effect of the cast-in-place thermal insulation beams, columns, and shear walls
