Cold and heat preventing bridge joint for cantilever slab component and building with cold and heat preventing bridge joint

Abstract

The invention provides a cold and heat preventing bridge joint for a cantilever slab component and a building with the cold and heat preventing bridge joint. The cold and heat preventing bridge joint comprises a main floor slab, a balcony slab, a tension piece and a heat preservation box. The heat preservation box is arranged between the main floor slab and the balcony slab. The tension piece penetrates through the heat preservation box, and the two ends of the tension piece stretch into the main floor slab and the balcony slab correspondingly to be fixedly connected with the main floor slab and the balcony slab. The heat preservation box comprises a box body and a compression piece. The box body is filled with a heat preservation material and used for preventing heat transfer between the main floor slab and the balcony slab. A mounting hole is formed in the box body. The compression piece is inserted into the mounting hole and used for bearing the pressure of the main floor slab and the balcony slab. According to the cold and heat preventing bridge joint for the cantilever slab component and the building with the cold and heat preventing bridge joint, on the premise that the structure meets the requirements for safety, economy and durability, a structural heat bridge at the balcony part is avoided, and the purposes of energy conservation and heat preservation are achieved.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a cold and heat-proof bridge node used for a cantilevered plate member and a building thereof. Background technique [0002] The performance of the building envelope is the key to building energy conservation, but the extensive application of reinforced concrete in practical engineering has led to a large number of building thermal bridges in the building envelope, which increases the energy consumption of the building. [0003] Improving the thermal insulation level of the envelope structure is the key to reducing building energy consumption and realizing energy saving and emission reduction. Traditional balcony slabs are connected to the main structure, forming a thermal bridge, which is a weak link in building energy conservation. In winter, due to the heat outflow at the balcony node, the heat in the room is lost, resulting in a significant increase in heating cost...

AI Technical Summary

Problems solved by technology

In winter, due to the heat outflow at the balcony node, the heat in the room is lost, resulting in a significant increase in heating costs and energy consumption, and the internal temperature of the adjacent room may be significantly lower than the dew point temperature

This creates harmful environmental conditions for plaster and paint, which can further deteriorate the building if it is continuously exposed to condensation

[0004] The key to reducing the thermal bridge of the balcony structure lies in the continuity of the insulation layer of the outer wall enclosure structure at the balcony node, but the traditional balcony has a main floor inside and a balcony slab outside, so thermal bridges are unavoidable
