Steel keel building wall and foundation heat insulation bridge structure and construction method

Abstract

The invention discloses a steel keel building wall and foundation heat insulation bridge structure and a construction method. The heat insulation bridge structure comprises wall steel vertical columns, a wall steel keel bottom beam, a base wall / beam, an indoor ground concrete cushion, an indoor ground heat insulation layer, an indoor ground concrete structure layer, a base wall / beam heat insulation layer, a wall heat insulation layer, a leveling layer, a moisture / water-resistant layer, a bonding slurry layer, heat insulation bridge supporting blocks, a heat insulation bridge heat preservationplate and a heat insulation bridge bolt connecting component. The heat insulation bridge bolt connecting component comprises a heat insulation bridge screw, a bottom supporting plate, a leveling nut,a tightening nut and a tightening spacer. The construction method includes the steps: preparing the leveling layer and the moisture / water-resistant layer at the top end of the base wall / beam, and screwing the leveling nut and the bottom supporting plate in the heat insulation bridge screw; coating the upper surface of the moisture / water-resistant layer with the bonding slurry layer, and mounting the heat insulation bridge heat preservation plate and the heat insulation bridge supporting blocks; hoisting a steel keel building wall onto the base wall / beam, and fixedly connecting the steel keel building wall with the base wall / beam; laying the indoor ground heat insulation layer and the indoor ground concrete structure layer; mounting the wall and the base wall / beam heat insulation layer.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a structure and a construction method of a thermal break bridge at the foot of a steel keel building wall. Background technique [0002] Building thermal bridges refer to reinforced concrete or metal beams / columns / ribs / fittings and other parts in the enclosure structures such as exterior walls and roofs. Due to the strong heat transfer capacity of these parts, the heat flow is relatively dense, and the inner surface temperature is relatively low. called a thermal bridge. [0003] Taking the steel keel building wall as an example, the foot of the wall is at the contact position between the building wall and the ground, and is the node where multiple components such as the building wall, building foundation wall / beam, and indoor ground meet. It is difficult to consider the balance of design requirements such as structure, waterproof, and heat-breaking ...

[0003] Taking the steel keel building wall as an example, the foot of the wall is at the contact position between the building wall and the ground, and it is the node where multiple components such as the building wall, building foundation wall / beam, and indoor ground meet. It is difficult to consider the balance of design requirements such as structure, waterproof, and heat-breaking bridges

[0004] Usually, the building wall and indoor floor are directly connected to the building foundation wall / beam, and the indoor heat will be transferred from the building foundation wall / beam to the ground through the building wall and indoor floor, resulting in heat loss
