    Abstract

    A structure for blocking heat transfer through a thermal bridge of a building, includes an inner visual glass curtain wall, an outer visual glass curtain wall, an indoor metal frame, an outdoor metal frame, an outer decorative metal cover, a first thermal break strip, a second thermal break strip, a first nylon thermal break block and a second nylon thermal break block. The first thermal break strip, which is located among the outdoor metal frame, the indoor metal frame, the first nylon thermal break block and the second nylon thermal break block, is an aerogel thermal insulation blanket. The second thermal break strip, which is located among the indoor metal frame, the second nylon thermal break block, the outer decorative metal cover and the inner visual glass curtain wall, is another aerogel thermal insulation blanket.

    Description

    DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

    [0009] Referring to the drawing, a structure for blocking heat transfer through a thermal bridge of a building according to a preferred embodiment of the present invention is illustrated, which comprises an outer visual glass curtain wall 61, an inner visual glass curtain wall 62, an indoor metal frame 63, an outdoor metal frame 64, a metal component which is embodied as an outer decorative metal cover 66, a first thermal break strip 68, a second thermal break strip 69, a first nylon thermal insulation block 65 and a second nylon thermal insulation block 67.

    [0010] Preferably, the indoor metal frame 63 and the outdoor metal frame 64 are both aluminum alloy frames. The outdoor metal frame 64 is connected to the indoor metal frame 63 by the first nylon thermal insulation block 65 and the second nylon thermal insulation block 67. The inner visual glass curtain wall 62 is fixed to the indoor metal frame 63 by structural silicone sealant and the outer visual glass curtain wall 61 is fixed to the outdoor metal frame 64 and the indoor metal frame 63 by structural silicone sealant. The outer decorative metal cover 66 is an aluminum alloy decorative cover and is clamped on the outdoor metal frame 64, the outer visual glass curtain wall 61 and the inner visual glass curtain wall 62. The first thermal break strip 68, which is embodied as an aerogel thermal insulation blanket, is installed among the outdoor metal frame 64, the indoor metal frame 63, the first nylon thermal insulation block 65 and the second nylon thermal insulation block 67. The second thermal break strip 69, which is embodied as another aerogel thermal insulation blanket, is installed among the indoor metal frame 63, the second nylon thermal insulation block 67, the outer decorative metal cover 66 and the inner visual glass curtain wall 62. The commercially available aerogel thermal insulation blanket (Aerogel) is manufactured by Warmframe Corporation of China, Cabot Corporation and ASPEN Corporation of United States, with the thermal conductivity in a range of 0.015-0.021 W/(m.Math.k).

    [0011] The embodiment set forth above is only described as a preferred embodiment and is not intended to limit the scope of the present invention. It will be understood by those skilled in the art that various modifications and improvements to the technical solution of the present invention may be made without departing the design spirit of the present invention, which all fall into the scope as defined by the claims of the present invention.

    Practical Applicability

    [0012] The structure for blocking heat transfer through a thermal bridge of a building according to the present invention can save about 1.4 KWh of electricity per square meter in one year and also can save about 120 RMB of construction cost per square meter. There are total about 50 million square meters of new building projects every year in China, and about one percent of the buildings can use the structure of the present invention, so in one year the structure for blocking heat transfer through the thermal bridge of the building according to the present invention can save about 700 thousand KWh of electricity and 60 Million RMB of construction cost totally.

    [0013] The structure for blocking heat transfer through the thermal bridge of the building according to the present invention has simple structure, convenient construction technology, great structural strength, excellent fireproof performance, low comprehensive construction cost and substantially improved energy-saving effect of the curtain wall.
