Passive energy-saving bridge-cutoff window sleeve

Abstract

The invention provides a passive energy-saving bridge-cutoff window sleeve, and belongs to one of building materials. The passive energy-saving bridge-cutoff window sleeve comprises a sleeve body molded by a heat insulation material, wherein a window frame groove communicated end to end is formed in the inner sleeve surface of the sleeve body along the circumference; a window frame and window hole connecting piece is embedded in the sleeve body positioned at the bottom of the window frame groove; and a fireproof isolation layer is arranged on the surface of the sleeve body. The passive energy-saving bridge-cutoff window sleeve is characterized by comprising the sleeve body molded by the heat insulation material, wherein the window frame groove communicated end to end is formed in the inner sleeve surface of the sleeve body along the circumference; the window frame and window hole connecting piece is embedded in the sleeve body positioned at the bottom of the window frame groove; and the fireproof isolation layer is arranged on the surface of the sleeve body. A window is mounted in a window hole of an outer wall through the window sleeve, so that the assembly requirement is realized, the passive energy-saving requirement is satisfied while a traditional auxiliary frame is replaced, the air tightness between the window and a structural hole is greatly improved, and the field construction is convenient and fast.

Description

technical field [0001] The invention relates to the construction field, and specifically provides a passive energy-saving broken bridge window cover. Background technique [0002] Passive buildings use the good thermal insulation performance of the building itself, without using traditional air-conditioning, heating and other active heating and cooling methods, and passively use heat from radiators such as solar radiation, human body heat, indoor lighting, and electrical heat dissipation, so that investment Less energy can meet the energy needs of building heating and cooling, energy saving and environmental protection; in recent years, the country has vigorously advocated energy-saving passive buildings, and passive buildings are mainly improved and realized by maintenance systems, that is, strengthening the external insulation system of buildings, while windows The airtight performance of the passive house is one of the important indicators to ensure the building performan...

[0002] Passive buildings use the good thermal insulation performance of the building itself, without using traditional air-conditioning, heating and other active heating and cooling methods, and passively use heat from radiators such as solar radiation, human body heat, indoor lighting, and electrical heat dissipation, so that investment Less energy can meet the energy needs of building heating and cooling, energy saving and environmental protection; in recent years, the country has vigorously advocated energy-saving passive buildings, and passive buildings are mainly improved and realized by maintenance systems, that is, strengthening the external insulation system of buildings, while windows The airtight performance of the passive house is one of the important indicators to ensure the building performance of the passive house. Usually there is a certain gap between the outer opening of the window frame and the inner opening of the window opening. Filling and sealing styrofoam and other fillers block cold and heat bridges and avoid air leakage, but it is difficult to fill narrow gaps, and the filling density of wide gaps is uneven, the filling quality is not easy to control, the labor intensity is high, and it is difficult to observe when filling the gaps in the outer window frame Controlling the quality is dangerous; a large number of experiments at home and abroad have proved that the window becomes the biggest weak point of the cold and heat bridge of passive buildings, because the traditional window profile is thin and the structure is fixed. Carry out simple foaming treatment, whether the foaming is full and uniform cannot be detected, and the profile is too thin, which causes slow frost on the inside of the window frame, condensation on the wall inside the window, air leakage between the window and the structure, and finally forms the largest thermal bridge area of ​​the building; to improve The airtight effect between the window and the window hole. The Germans suggested that the window should be installed on the outside of the external insulation layer of the external wall, but the problem is that it seriously affects the appearance and facade effect of the building, and the size of the window in modern buildings is usually large. When opening and closing the interior door When the indoor air pressure changes or the external wind pressure is large, the window will vibrate, resulting in gaps in the sealing filler between the outer opening of the window and the inner opening of the window opening or between the outer insulation, resulting in poor airtight effect. How to install it in the window opening Windows and making them able to meet the airtightness requirements of passive buildings has become a technical problem that urgently needs to be studied and solved in this field.
