Construction technology for processing glass curtain wall into hollow glass curtain wall

Abstract

The invention discloses a construction technology for processing a glass curtain wall into a hollow glass curtain wall. The construction technology comprises a main frame fixing the glass curtain wall and includes steps of 1) contiguously connecting spacing bars for assembling a support frame to inner edges of the main frame by sealant spread at corners of the spacing bars; 2) attaching the integral glass to the spacing-bar frame so as to form a cavity among the spacing-bar frame, the glass curtain wall and the glass; and 3) injecting sealant to fill space between the spacing-bar frame and the main frame and gaps between the glass and the main frame and reserving two air holes so that the cavity is a sealed cavity with two reserved air holes. After modification, heat transfer coefficient of the hollow glass curtain wall is one third of that of the glass curtain wall, heat transfer coefficient is greatly decreased, and ideal energy-saving effect can be achieved. Furthermore, modification is completed on the original glass curtain wall, so cost is lower.

Description

technical field [0001] The invention relates to a construction technique for on-site transformation of a glass curtain wall into a hollow glass curtain wall, and belongs to the technical field of building energy conservation. Background technique [0002] In our country, building energy consumption accounts for 30% of the energy consumption of the whole society, and together with industrial energy consumption and transportation energy consumption, it is called my country's three major "big energy consumers". It is difficult to reverse the upward trend of rigid demand for building energy consumption, which has become an urgent problem to be solved in my country's energy conservation and emission reduction. In the city, it is not only the new buildings that rise every day, but also the old buildings that stand in the city. Therefore, the energy-saving renovation of old buildings has become the highlight of the construction industry to reduce energy consumption. [0003] A lar...
