Description

Passive combined wall body without heat bridge wood structure and preparation method thereof
Technical Field
The invention belongs to the technical field of constructional engineering, and particularly relates to a passive combined wall body without a heat bridge wood structure and a preparation method thereof.
Background
The wood structure building is a marginal color low-carbon building, and is the only renewable resource among four raw materials (steel, cement, plastic and wood) because wood is a biomass material. The wood can absorb 1 ton of carbon dioxide and release 0.75 ton of oxygen every 1 cubic meter of wood produced in the growing process, the carbon fixation amount of the wood product is more than the carbon released in the production and use processes, and the wood product is the only 'negative carbon' type material. In addition, the wood is a porous natural material, has a low thermal conductivity coefficient which is about one tenth of that of concrete blocks or bricks under the same specification, has a thermal conductivity coefficient which is about four percent of that of steel, and has excellent heat insulation performance. Compared with a concrete stop structure wall, a brick-concrete structure wall and a light steel structure wall, the wood structure wall with the same thickness has a lower heat transfer coefficient under the same thermal environment, and the building energy-saving effect is more excellent.
The outer envelope structure of the wooden building mainly comprises components such as an outer wall, a roof, an outer window, an outer opening and the like, and plays a role in resisting wind, rain, sunlight irradiation, temperature change and the like. When the wood structure building is used, heat exchange is always carried out between the inside and the outside of the house through the outer enclosing structure, and the running energy consumption of the building is increased due to the loss or the increase of the heat. In order to reduce the energy consumption of the building operation, the heat insulation performance of the outer enclosure structure is inevitably improved, and in the outer enclosure structure, the proportion of the wall is the largest and accounts for about 70% of the whole building, so the first work and the key point of reducing the energy consumption of the building operation are to improve the heat insulation performance of the wall.
The 'passive house' is proposed by the professor adam mussen, sweden and the fiestteh, germany in the last 80 th century on the basis of low energy consumption buildings. Germany established the first passive room in the world in 1990. The "passive house" institute was established in europe in many countries. The development of the german building energy saving standard goes through 3 development stages: high energy consumption-low energy consumption-passive room. Nowadays, the technology of the passive house in Germany is quite mature, and the energy-saving standard of the Germany building requires: the heating energy consumption of the 'passive room' per unit building area is lower than 15k Wh per year (square meter. a). When heat is supplied through inlet air, the heating heat load per unit area contains 10W, and the heat load for preparing domestic hot water is not included. From the energy-saving aspect, the numerical values are far lower than the current 65% energy-saving standard in China and are in the international leading ranks. Since the research and practice of the 'passive house' construction starts from germany and is mostly designed according to the germany climate conditions, the technical measures of the 'passive house' construction in most of europe today aim at the minimization of the heating requirement in winter. While the energy conservation of buildings is emphasized, the German passive house carries out index limitation on indoor temperature, carbon dioxide concentration, indoor humidity and the like. The comfort level of the 'passive house' is improved while the energy conservation of the building is concerned.
In cold environments, passive buildings do not require heating equipment, and can achieve a more comfortable indoor environment by only maintaining the structure. Compared with the traditional building, the passive building has the following obvious advantages:
(1) the energy consumption is low. The fresh air system of the passive building can provide enough fresh air and can recycle a large amount of hot air, so that the energy consumption requirements of heating and refrigerating are reduced, and the indoor suitable temperature and humidity are ensured. Compared with the current national energy-saving design standard, the heating energy consumption of the passive building can be reduced by more than 85%;
(2) the heat preservation and insulation performance is good. The enclosure heat-insulation system with good passive building ensures that the surface temperature of the inner wall of the building is stable and uniform and is close to the indoor temperature, and has good air tightness and sound insulation effect;
(3) and (4) integrally building. The passive building adopts the design of no heat bridge and high air tightness, high-quality material components, and the integration of fine construction and building decoration, so that the building has higher quality and longer service life.
Therefore, under the support of the national vigorous development of energy-saving buildings, green buildings and sustainable buildings, the development of passive buildings has important significance for the problem of severe environment and resource shortage at present, and is an effective means for improving the environment and harmony and coexistence of the buildings and the nature.
Therefore, it is necessary to invent a passive combined wall body without a heat bridge wood structure and a preparation method thereof, so as to improve the fire-resistant grade stress performance and the heat-insulating and energy-saving functions of the wood structure combined wall body. .
