Node structure for energy saving improvement of internal circulation glass curtain wall and construction method thereof

Abstract

The invention discloses a node structure for an energy saving improvement of an internal circulation glass curtain wall. The node structure comprises existing building curtain wall stand columns, hollow glass, a heat insulation break bridge profile assembly, a top heat insulation break bridge profile, a bottom heat insulation break bridge profile, a ventilator and a fresh air pipeline, wherein thehollow glass is arranged on the indoor side of an existing building curtain wall, an internal circulation type dual-layer curtain wall is formed with the hollow glass and the outside glass curtain wall, an air layer is formed between the hollow glass and the existing building curtain wall, the heat insulation break bridge profile assembly is used for installing the hollow glass, and comprises twofirst heat insulation break bridge profiles, two second heat insulation break bridge profiles, a first heat insulation strip and a second heat insulation strip, the top heat insulation break bridge profile is used for fixing the top of the hollow glass, the bottom heat insulation break bridge profile is fixedly arranged on a beam at the bottom of the existing curtain wall, the ventilator is arranged in the bottom heat insulation break bridge profile, and indoor air of the air layer enters a fresh air system through the fresh air pipeline for filtering and circulating. The node structure purifies indoor air and meanwhile prevents indoor heat from diffusing, thereby saving energy.

Description

technical field [0001] The invention relates to the technical field of energy-saving transformation of existing building curtain walls, in particular to a node structure and construction method for energy-saving transformation of inner circulation glass curtain walls. Background technique [0002] The scale of existing buildings in my country is huge, and the proportion of their energy consumption in the energy consumption of the whole society is gradually increasing. As an external protective structure, the building curtain wall has relatively low energy-saving requirements compared with foreign developed countries. With the continuous development of technology, my country's emphasis on curtain wall energy-saving has been increasing, and more and more existing buildings need energy-saving renovation. . However, the energy-saving renovation of existing building curtain walls is very difficult, the cycle is long, and the cost is high, so the measures for micro-renovation are ...
