Safe and economic double curtain wall borne by building structure

Abstract

The invention provides a safe and economic double curtain wall borne by a building structure. The curtain wall comprises horizontal support plates (10) which extend along a supporting member of a window of an inner curtain wall in each layer in the building structure, wherein an outer curtain wall (20) is positioned and fixed on the upper surface of the horizontal support plate (10); an upper exhaust ventilation port (21) and a lower inlet ventilation port (22) are arranged above and under the outer curtain wall (20) respectively; and each layer is independent in space. The curtain wall saves materials on structure and connection, saves occupied space, high cost, complicated construction and fussy steel structure, improves the utilization area of the building, reduces the cost, shortens construction period, reduces long-term maintenance cost, has time and manpower saving, simple structure, low construction cost, high safety, convenient maintenance, low cost and the like, leads easy layer to circulate independently, reduces the problem of heat concentration on higher floor, and is integrated with sun-shading, heat insulating, sound insulating, warming, energy saving, heat preserving, dust proofing, mosquito and insect preventing, ventilating and other energy-saving environment-friendly functions in the whole system.

Description

technical field [0001] The invention relates to building external protection facilities, in particular to a construction method and product for building exterior decorative curtain walls. Background technique [0002] Curtain walls have been widely used in various buildings, but there are still many problems in the design and application of architectural curtain walls. First, the existing building curtain wall technology and products are all products introduced in the 1980s. Although they have been improved for more than 20 years, their basic form and structure have not changed much. Poor thermal insulation performance, no temperature regulation layer, no sunshade and ventilation devices. As a result, the energy consumption of indoor cooling and heat preservation is high, the air quality is poor, and the microclimate environment is harsh, which makes people's life uncomfortable in this indoor environment, low work efficiency and unfavorable for health. If you want to impro...

AI Technical Summary

Problems solved by technology

The double-layer curtain wall designed and installed by this method replaces the metal structural components of the existing double-layer curtain wall with the reserved building components, which solves the need to add a curtain wall support structure outside the main structure of the building in the prior art, and its own structure is complex and expensive. Technical issues of height, large footprint and poor security
