Description

Curtain wall embedded part for heat-proof bridge in low-temperature environment

Technical Field

The utility model relates to a structure is handled to the heat protection bridge, especially relates to a built-in fitting that is used for heat protection bridge under low temperature environment, mainly is applied to the curtain of building. .

Background

In the process of rapid urbanization and modernization of China, the building energy consumption accounts for about 30 percent of the total energy consumption. According to the world energy prospect issued by the world energy organization (IEA), the total energy consumption of China reaches 58.1 hundred million tons of standard coal by 2030, wherein the energy consumption of buildings reaches 15.2 hundred million tons of standard coal. The research of the American Energy Information Agency (EIA) indicates that the energy consumption of China (2030) reaches 64.04 hundred million tons of standard coal, and the energy consumption of buildings reaches 12.93 hundred million tons. Obviously, the method is unsustainable for China and human beings, so that passive ultralow-energy-consumption green buildings are vigorously developed, and the method is a necessary way for building energy conservation and emission reduction in the whole society.

The passive house advocates energy conservation, economy, comfort and building aesthetics, and reduces the requirements of heating and refrigerating energy sources by optimizing the building mode. The main measures comprise good heat preservation, efficient energy-saving doors and windows, sun shading in summer, structural heat bridge prevention, an airtight outer protective structure and an organized indoor fresh air supply and heat recovery system.

According to the experience of passive rooms, avoiding heat bridges is the most economical energy-saving measure. The effect of protecting the building and improving the comfort is obvious. Under the common temperature and humidity of a living room, the passive room designed by the heat-proof bridge has no inner surface dewing phenomenon any more so as to avoid the generation of indoor mould.

Because the curtain wall is used for decorating the exterior of the building and is also a part of the building, improper curtain wall design directly influences the operation energy consumption of the building. In conventional engineering, the built-in fitting is usually directly anchored on the wall body, and the installation of the curtain wall foundation of being convenient for is fixed, and they are made by the metal mostly, have better heat conductivity, can be because there is the difference in temperature inside and outside the building to produce the heat bridge phenomenon through the built-in fitting at the position that does not have the heat bridge of preventing to handle, cause the inside heat consumption of building to increase, and energy cost improves to make interior wall and wall body surface produce the comdenstion water, lead to wall body and wall body surface moldy.

Disclosure of Invention

An object of the utility model is to provide a structure is handled to heat-proof bridge of built-in fitting under low temperature environment to solve the inside heat consumption increase of building that the better causes of traditional built-in fitting heat conductivility that proposes in the above-mentioned background art, the wall body dewfall, go mildy destroyed problem.

The utility model provides a technical scheme is, a curtain built-in fitting that is used for heat protection bridge under low temperature environment, including steel sheet one, glass steel groove, heat insulating block, fastener, draw-in groove one, built-in fitting, wall body, steel sheet two, draw-in groove two, heat preservation.

The embedded part and the first steel plate are embedded in the wall body, the glass fiber reinforced plastic groove, the heat insulation block and the second steel plate sequentially pass through the fasteners to be fixed on the first embedded part clamping groove, the second steel plate is provided with a second clamping groove, the bolt penetrates through angle steel of a curtain wall fixedly connected with the second clamping groove, adverse effects of high-temperature welding of the support on heat insulation materials are avoided, and the heat insulation layer is fixed on the surface of the wall body.

The beneficial effects of the utility model reside in that:

1) the utility model provides a curtain built-in fitting that is used for heat protection bridge under low temperature environment is applicable to in the environment of the inside and outside great difference in temperature of building.

2) The fastener is four piece at least FRP bolts and the two nuts that match with it, prevents to be become flexible by fixed component and slides, guarantees engineering safety. The FRP is light and hard, is non-conductive, has high mechanical strength, is corrosion-resistant and has low heat conduction, so that the heat bridge phenomenon generated by the second steel plate can be effectively prevented, and the fixing effect of the FRP is ensured.

3) The first steel plate is provided with a strip-shaped seam, the middle part of the seam is wide, the two sides of the seam are narrow, the FRP bolt is embedded into the embedded part and the first steel plate from the middle wide part, and then the FRP bolt is translated to the narrow positions on the two sides to be fixed, so that construction operation is facilitated.

4) The heat insulation block adopts high-strength polyurethane.

5) The high-strength polyurethane is arranged in the glass fiber reinforced plastic groove.

6) Two steel sheet set up draw-in groove two, be convenient for connect curtain angle steel bolt's setting, avoid support high temperature welding to the adverse effect of insulation material thermal insulation performance, because two opposite sides of steel sheet have laid high strength polyurethane, have effectively separated the bolt transmission heat of connecting the curtain.
