Description

Outer window mounting structure suitable for prefabricated sandwich wallboard of ultralow energy consumption building

Technical Field

The utility model relates to the field of installation of prefabricated sandwich wallboard external windows, in particular to an external window installation structure suitable for ultra-low energy consumption buildings.

Background

The installation of the external window of the existing prefabricated sandwich wallboard is usually realized by fixing the external window in an anti-corrosion wood block pre-buried in an insulating layer by using expansion bolts. When the prefabricated sandwich wall board is applied to an ultralow-energy-consumption building, the external window is installed in the same way as the anticorrosive wood block.

The existing installation mode of the prefabricated sandwich wallboard external window of the ultralow energy consumption building adopts glass fiber reinforced polyurethane filled with foaming polyurethane to replace an anti-corrosion wood block as a fixing piece of the external window. Different from the interval arrangement of the anti-corrosion wood blocks and the periphery of the window opening, the glass fiber polyurethane is arranged along the through length of the window opening.

The outer window mounting structure of the prefabricated sandwich external wall panel of the traditional assembled ultralow energy consumption building is characterized in that windows are fixed on anti-corrosion wood blocks A, the wood blocks are located on an insulation layer, the wood blocks are arranged at intervals, the insulation layer of the sandwich external wall panel needs to be cut by adopting a vacuum insulation board S (insulation board) due to lower heat transfer coefficient of the ultralow energy consumption building outer wall, irregular anti-corrosion wood blocks arranged at intervals are inconvenient to process the insulation layer, and the vacuum insulation board between the irregular anti-corrosion wood blocks belongs to insulation materials of an unconventional size, so that the manufacturing cost of the prefabricated wall panel is correspondingly increased. The insulation materials with different sizes also need to be accurately adhered to the corresponding positions, so that the manufacturing period of the sandwich wallboard is correspondingly increased. In addition, a waterproof and breathable film is arranged between the anti-corrosion wood block and the window frame, and a waterproof and vapor-proof film is arranged in the room.

Yet another structure is: the number of the special-shaped vacuum heat insulation plates can be reduced by continuously arranging the anti-corrosion wood blocks around the window opening Q, but the heat transfer coefficient of the anti-corrosion wood block A is higher, so that the installation heat bridge of the outer window is not reduced; the weight of the anti-corrosion wood block is large, and the anti-corrosion wood block is inconvenient to fix; and the linear expansion coefficient of the reinforced concrete has a larger difference from that of the reinforced concrete (6.8-12.7X10-6), and the large-area use of the reinforced concrete can easily cause large-area cracking in the manufacturing and curing process of the prefabricated wallboard, so that a new installation structure needs to be found.

Therefore, how to provide an external window mounting structure which has a short manufacturing period and low cost and can keep the temperature is a problem to be solved.
