Description

Insulation node structure of the upper roof of passive house

technical field

The utility model relates to a high-performance thermal insulation structure designed without thermal bridges, in particular to a thermal insulation node structure on the roof of a passive house.

Background technique

With the country's rapid promotion of energy conservation and emission reduction and the rapid development of building energy conservation, it is imperative to design new buildings and existing buildings with external thermal insulation. However, the external wall insulation industry developed relatively late in China, and has about 20 years of engineering experience, so there are many defects and deficiencies in the design. In recent years, with the development of my country's building energy-saving industry and the improvement of building standards, more new-style buildings have gradually entered people's lives.

As a kind of ultra-low energy buildings, passive houses are gradually appearing before our eyes. Passive buildings reduce building energy consumption to a minimum through their new architectural design and new equipment. Among them, no thermal bridge design is one of the key points of external thermal insulation design. Due to the design concept of cutting off all thermal bridges required in passive houses, the upper part of the roof needs to be designed differently from ordinary external insulation to avoid structural thermal bridges and reduce building energy-saving effects.

Contents of the invention

The purpose of this utility model is to provide a passive house roof thermal insulation node structure aimed at the defects existing in the prior art.

Its technical solution is: Passive house upper roof thermal insulation node structure, including the passive house upper roof cast-in-place concrete roof panel, on the upper surface of the roof panel is provided with an insulation layer, the insulation layer is sequentially attached to the roof The waterproof vapor barrier layer on the upper surface of the panel, the first layer of insulation board, the second layer of insulation board, the first leveling layer, the waterproof and breathable layer, the second leveling layer and cement mortar are covered with non-slip floor tiles.

Wherein, the first leveling layer is a cement mortar layer, and the second leveling layer is a fine stone concrete layer. The first rock wool board and the second rock wool board with the same width and thickness as the first layer of insulation board and the second layer of insulation board are laid on the side of the insulation layer close to the parapet.

Compared with the prior art, the utility model has the following advantages: simple structure, reasonable design, convenient installation, improving the energy-saving effect of the building by setting a waterproof layer and a thermal insulation layer different from the common roofing method, and ensuring the human roofing on the outer wall straight and beautiful.

detailed description

With reference to Fig. 1, a kind of thermal insulation node structure of the upper roof of the passive house comprises the roof panel 1 of the cast-in-place concrete of the upper roof of the passive house, and an insulation layer is arranged on the upper surface of the roof panel 1, and the insulation layer is pasted sequentially. The waterproof and vapor barrier layer 2 attached to the upper surface of the roof panel 1, the first layer of thermal insulation board 3, the second layer of thermal insulation board 4, the first leveling layer 5, the waterproof and breathable layer 6, the second leveling layer 7, and cement mortar to lay non-slip floor tiles 8. The first leveling layer 5 is a cement mortar layer, and the second leveling layer 7 is a fine stone concrete layer. The first rock wool board 9 and the second rock wool board 10 with the same width and thickness as the first layer of insulation board 3 and the second layer of insulation board 4 are laid on the side of the insulation layer near the parapet.

During construction, on the upper surface of the cast-in-place concrete roof slab 1 on the upper mandible roof of the passive house, lay insulation boards 3 and 4 with the same thickness as the outer wall design, and the same double-layer boards are pasted with 1/2 board seams. The thermal bridge at the board seam is solved by the way that the laminate seams are opposite, and waterproof layers are laid on the upper and lower sides of the insulation boards 3 and 4. The upper surface of the cast-in-place concrete roof panel 1 is laid with a waterproof vapor barrier layer 2 and a waterproof and breathable layer 6 to avoid water vapor exchange between the roof insulation panels 3 and 4 and the cast-in-place concrete roof panel (1), and the water vapor in the roof insulation system can Leaving the system along the top of the roof.

The utility model has the advantages of simple structure, reasonable design, and convenient installation. By setting a waterproof layer and a thermal insulation layer different from common roofing methods, the energy-saving effect of the building is improved, and the straightness and beauty of the human roof on the outer wall are guaranteed.
