Description

Semi-embedded passive outer window mounting structure

Technical Field

The utility model relates to an ultra-low energy consumption building technical field of passive form, concretely relates to semi-embedded passive form exterior window mounting structure.

Background

The passive ultra-low energy consumption building originates from Germany, is an internationally recognized energy-saving building integrating high comfort level, low energy consumption and economy, and has extremely high requirements on the sealing and heat insulation performance of the outer protective structure of the building. The common installation mode in the market at present is external hanging type installation, and in the construction step, an external wall structure needs to be constructed firstly, then a passive external window is externally hung and fixed on an external wall through expansion bolts, and finally an insulating layer is externally pasted and constructed.

The external hanging type installation mode can enable the passive external window and the heat insulation layer to form a continuous heat insulation system, and the loss of energy from the external window is reduced. However, in the practical application process, the installation mode can only be used for a thin plastering system adhered after heat preservation, and the replacement and maintenance are difficult to carry out after the construction of the external window, so that the diversity, safety and durability of the passive ultra-low energy consumption building in the construction are directly limited. The thickness of the outer heat-insulating layer of the passive ultra-low energy consumption building is very thick, generally 2-3 times of that of a common building, the thick and heavy heat-insulating layer can only be fixed on the surface of the building through pasting and heat-insulating nails, and the heat-insulating layer is likely to fall off and cause harm due to the aging of pasting materials and heat-insulating nails in the conventional service life of the building of 50 years. And if the passive external window installed in an external hanging mode needs to be replaced, the passive external window can be replaced only by breaking the external heat insulation mode and removing heat insulation materials around the opening of the window. Particularly, when the passive ultra-low energy consumption building adopts an external wall sandwich heat-insulation cast-in-place concrete system to solve the problems of easy falling off of heat insulation and low safety performance, and the safety and durability of an external heat-insulation system are improved, the traditional external hanging type installation mode is completely inapplicable.

Therefore, how to design a mounting structure of a passive external window, which can be generally applied to passive ultra-low energy consumption buildings, has become an urgent technical problem to be solved.
