Low-energy-consumption building heat preservation window structure

Abstract

The invention relates to a low-energy-consumption building heat preservation window structure which comprises a concrete wall body, a window formed in the concrete wall body and an outer window frame arranged on the outer side of the window, the outer window frame is fixedly arranged on the concrete wall body through a window frame fixing piece, and a heat insulation gasket is arranged between the window frame fixing piece and the concrete wall body. Two layers of insulation boards are arranged on the outer side of the concrete wall body, and the whole outer side of the window frame fixing piece is covered with a waterproof breathable film. The outer window frame and the concrete wall body are connected through the window frame fixing piece, the heat insulation gasket is arranged between the outer window frame and the concrete wall body, a heat bridge between the outer window frame and the concrete wall body is blocked, heat exchange between the window and the outdoors is reduced, and the purposes of saving energy and reducing consumption are achieved.

Description

technical field [0001] The invention relates to the field of building structures, in particular to a low energy consumption building thermal insulation window structure. Background technique [0002] A passive house is a master of various technical products, a house where the sum of all primary energy consumed does not exceed 120 kW·h / (square meter·year) by making full use of renewable energy. Such a low energy consumption standard is achieved through high thermal and acoustic insulation, a highly airtight building exterior and renewable energy. [0003] In existing buildings, doors and windows are the most heat-exchanging structures with the outside world, especially windows. By setting doors and windows, windows can meet the needs of ventilation and lighting, but at the same time, it is easy to form thermal bridges, resulting in heat exchange with the outside, and causing Lack of airtightness. In the prior art, the window structure is often modified and designed to incre...
