Passive house bay window heat preservation joint structure and construction method thereof

Abstract

The invention discloses a passive house bay window heat preservation joint structure and a construction method of the passive house bay window heat preservation joint structure. The passive house baywindow heat preservation joint structure comprises a wall body, bay windows and heat preservation blocks, wherein the heat preservation blocks include side heat preservation blocks, top heat preservation blocks, bottom heat preservation blocks, a first connecting heat preservation block and second connecting heat preservation blocks; each side heat preservation block is in an L shape in the vertical direction; each top heat preservation block is in an L shape in the transverse direction and is provided with first insertion-connection grooves; each bottom heat preservation block is in an L shape in the transverse direction and is provided with second insertion-connection grooves; the first connecting heat preservation block is in a plate shape, and the two side ends are inserted in the corresponding first insertion-connection groove and the corresponding second insertion-connection groove in a matching manner; each second connecting heat preservation block is in a plate shape, and the second connecting heat preservation blocks are arranged at the two ends of the first connecting heat preservation block; and adhesive connection is adopted between the heat preservation blocks and thewall body, between the heat preservation blocks and the bay windows, and between the heat preservation blocks. By improving the shape of the heat preservation blocks and prefabricating improved heat preservation block specifications according to the improved shape, the heat preservation blocks can be squeezed through an adhesion and pin insertion type connecting structure, so that the heat preservation blocks are firmly installed on the bay windows, and the construction efficiency is greatly improved. In addition, because of insertion-connection overlapping arrangement, the passive house bay window heat preservation joint structure has continuous airtightness and has a better heat preservation effect.

Description

technical field [0001] The invention belongs to the field of passive house construction, and in particular relates to a passive house bay window insulation node structure and a construction method thereof. Background technique [0002] A passive house is a master of various technical products, a house where the sum of all primary energy consumed does not exceed 120 kW·h / (square meter. year) by making full use of renewable energy. Such a low energy consumption standard is achieved through high thermal and acoustic insulation, a highly airtight building exterior and renewable energy. "Passive house" is a brand-new energy-saving building. It is a house that can meet the cooling and heating needs without actively supplying energy. In simple terms, it is a highly energy-saving and comfortable livable building. [0003] Because the external insulation thickness of passive house projects is generally thicker, for external bay windows, after laying the insulation layer outside the ...

AI Technical Summary

Problems solved by technology

[0004] The invention provides passive house bay window thermal insulation node structure and construction method, which is used to solve the problem that because the external insulation thickness of passive house projects is generally thicker, for external bay windows, after laying the insulation layer outside the bay window, it is necessary to pass insulation nails Fixing the insulation layer on the wall, because the distance between the upper and lower bay windows is small, the operating space is small, and the nailing operation of the insulation nails is relatively difficult, which makes the stability of the insulation layer poor and the insulation effect poor. question
