Abstract

The utility model belongs to the technical field of heat preservation windows, and discloses a log heat preservation passive window which comprises a square frame, the square frame is composed of four long-strip-shaped log beams with the width of 200 mm and the thickness of 60 mm in a mortise and tenon structure, the length of each log beam is consistent with the length and the width of a window opening, an L-shaped groove is formed in the middle of each log beam through a machine, a groove of 2 cm is carved in the bottom of each log beam, and 4-5 cm is reserved on the outer side of each log beam. Glass with thermal insulation performance is arranged in the frame body, the glass is embedded in the groove and is fixedly clamped by an L-shaped stainless steel strip, and a flexible material is padded between the glass and the stainless steel strip. A cross-shaped or T-shaped log frame can be additionally arranged in the middle of the square frame. The passive window provided by the utility model completely adopts the wood structure frame body and is free of metal materials such as aluminum materials, so that the heat preservation effect can be greatly improved. Due to the fact that the thickness of the frame body reaches 200 mm, the inward protruding part can effectively cover the section of the inner heat preservation layer, and the stability of the structure fixed to a window opening can be guaranteed.
