Description

Straw insulation board sandwich wall

technical field

The invention relates to a novel exterior wall heat-insulating sandwich wall, in particular to a straw heat-insulating board sandwich wall.

Background technique

According to statistics, the energy consumption per unit area of buildings in my country is still 3 to 5 times that of developed countries with similar climates. Building energy conservation is the most potential, most direct and effective way among various ways of energy conservation, and it is the most effective measure to alleviate energy shortage. Among the building energy consumption, the energy consumption caused by the external wall accounts for more than 50% of the total building energy consumption, so wall insulation is the key to realize building energy saving.

There are two forms of energy-saving walls: single energy-saving walls and composite energy-saving walls. Single energy-saving walls are represented by aerated concrete walls, but their use and development are hindered by problems such as safety, durability, and use functions. Composite energy-saving walls mainly include external wall internal insulation, external wall external insulation and sandwich wall technology. Due to the serious problem of cracks and the difficulty of avoiding thermal bridges and other shortcomings, the proportion of thermal insulation in the external wall has been decreasing year by year, and it has become a transitional and backward structural form. At present, the most widely used energy-saving wall at home and abroad is external wall insulation. The durability of external wall insulation projects in China is very serious, and it cannot guarantee a 25-year service life under correct use and normal maintenance conditions, and some projects can only be used for 3 to 5 years. More and more experts are aware of the durability of external wall insulation projects, and worry about the catastrophic consequences of nationwide large-scale or overall damage to external wall insulation projects in the next few years or ten years. The sandwich wall is the only durable energy-saving wall that can integrate load-bearing, thermal insulation (sound insulation) and decoration, and is suitable for different regions. At present, sandwich walls are filled with benzene boards, etc. The construction is complicated, the construction period is long, and quality problems are prone to occur in actual construction, which has affected the further promotion and application of this technology. The durability of energy-saving wall insulation layer has become the main problem faced by Chinese and foreign building energy-saving experts. It is urgent to find a durable energy-saving wall technology that is economical, simple and fast in construction, good in energy saving effect, and the insulation layer has the same life as the building.

External wall sandwich insulation is a durable and energy-saving wall that can integrate load-bearing, thermal insulation (sound insulation) and decoration, and is suitable for different regions. It is also a thermal insulation technology that can solve the problem of the same life span of the thermal insulation layer and the building. Filled exterior wall sandwich insulation technology usually uses benzene board as the sandwich insulation board. In actual construction, in the weak parts of insulation such as ring beams, windows, balconies, etc., the tie parts will cause damage to the benzene board. In addition, the cost of polystyrene board is relatively high. The above quality problems cause a large gap in the middle of the sandwich insulation wall, so that the hot and cold air convection is smooth, the heat loss is much larger than the design, and the insulation performance is greatly reduced, which has affected the technology. Promote the application further.

The sandwich wall currently researched and developed has Chinese Patent No. 201110265208.2, which discloses an invention patent named "A Self-insulating Reinforced Block Masonry Sandwich Wall"; The invention patent of "Manufacturing Process of Building Sandwich Wall"; Chinese Patent No. 201010197901.6 discloses an invention patent named "A Preparation Method of Building Sandwich Wall Insulation Material"; Chinese Patent No. 201010532212.6 discloses a patent named "A Sand-free Concrete The invention patent of the manufacturing method of the sandwich wall.

However, the construction problems of sandwich walls and the insulation problems of sandwich walls still need to be further resolved. The development of sandwich walls with straw insulation boards will promote the development of building energy conservation and wall insulation.
