A honeycomb type convection ventilation external wall thermal insulation device

Abstract

The invention discloses a cellular convection ventilation exterior wall heat insulation device, and relates to the technical field of heat insulation. The cellular convection ventilation exterior wall heat insulation device comprises a prefabricated heat insulation body, a cellular convection ventilation heat insulation module, an upper ventilation assembly and a lower ventilation assembly, wherein the prefabricated ventilation airflow channel is arranged in the prefabricated heat insulation body; the upper ventilation assembly is located at the upper end of the cellular convection ventilation heat insulation module and is communicated with the cellular convection ventilation heat insulation module; and the lower ventilation assembly is located at the lower end of the cellular convection ventilation heat insulation module and is communicated with the cellular convection ventilation heat insulation module. The cellular convection ventilation exterior wall heat insulation device has the beneficial effects that a cavity-type cellular convection heat preservation and insulation wall body penetrating up and down is achieved; through the arranged automatically controlled heat insulation airtight valve, the cellular convection ventilation exterior wall heat insulation device has ventilating and cooling performance in summer and heat preservation and insulation performance in winter; by a cellular bionic design, the structure is firm; and the cellular convection ventilation exterior wall heat insulation device and a prefabricated standard component are subjected to integral construction.

Description

technical field [0001] The invention relates to the technical field of thermal insulation walls, in particular to a honeycomb type convection ventilation external wall thermal insulation device. Background technique [0002] Actively promoting green buildings and building materials, vigorously developing prefabricated buildings, improving the standards and quality of construction projects, and improving the living environment have gradually become the focus of the construction industry. As an important part of the enclosure structure, the building exterior wall not only requires a certain structural strength, but also needs to have the function of thermal insulation to reduce the heat consumption of the enclosure structure and create a good indoor heat and humidity environment. Commonly used wall insulation mainly includes external wall internal insulation, sandwich insulation and external wall external insulation. External wall insulation has the advantages of good thermal...

AI Technical Summary

Problems solved by technology

[0003] (1) Traditional thermal insulation methods such as on-site foaming and pouring are limited by the technical level of the construction personnel, construction site conditions and climate environment, and are prone to thermal defects such as local thermal bridges and condensation, resulting in swelling, leakage, cracking, Phenomena such as shedding are common, affecting the life of building structures

[0004] (2) Common ventilation and convection walls have a certain performance of ventilation and cooling in summer and thermal insulation in winter, but they cannot adjust the weather resistance of reasonable ventilation and thermal insulation functions according to outdoor climate conditions

[0005] (3) It is difficult to integrate the existing thermal insulation devices with assembled standardized components
