Heat-insulating energy-saving building block utilizing industrial waste and with uniform heat path

Abstract

The invention discloses a heat-insulating energy-saving building block utilizing industrial waste. The heat-insulating energy-saving building block is composed of a base material 1, a blind hole 2, a blind hole 3 and a through hole 4, and the base material is composed of the industrial waste such as furnace slag and pulverized coal ash, building waste and cement according to a certain proportion and produced through hydraulic forming. Mechanical performance, heat insulativity, material consumption and building convenience of the building block are integrated, and optimized hole ratio is 45-60%. Internal hole type is optimized by reasonably matching the blind holes with the through hole, so that the heat path is enabled to be more uniform, cold-heat bridge during heat transfer of the building block is blocked, and heat insulativity of the building block is improved greatly. The building block can serve as a hollow building bock to be used solely and can be composited with a heat-insulating material for use, so that heat insulativity of the building block is further improved. The heat-insulating material which is filled can be an inorganic material such as foamed concrete and can also be an organic material such as EPS and XPS, and energy-saving designing standard requirements can be met without taking other heat-insulating measures on a built wall. The heat-insulating energy-saving building block has the advantages of high heat insulativity, building material saving, high mechanical strength, service life identical with a building and convenience in construction.

Description

technical field [0001] This patent relates to a building thermal insulation block brick, especially a thermal insulation and energy-saving block using industrial waste slag with a uniform thermal path. On the basis of ensuring the mechanical properties of the block, it can greatly improve the thermal insulation performance of the building wall and achieve energy saving. standard. technical background [0002] Energy is the foundation of human survival and the development of modern science and technology. With the increasing shortage of energy, how to improve energy efficiency and develop and utilize new renewable energy has become a worldwide problem to be solved. With the rapid development of the construction industry and the improvement of people's quality of life, building energy consumption has accounted for about 1 / 3 of the total energy consumption of the whole society, and it is showing a trend of continuous increase. Improving the thermal insulation performance of bu...

Problems solved by technology

[0004] However, the current self-insulating blocks are mostly designed with simple hole rows, which often have thermal bridges, making the overall heat transfer path of the block uneven. Although the block has a relatively good thermal insulation effect, the heat often Through the heat bridge or into the room, it will cause uneven cooling and heating of the wall, affect the local performance of the wall, and even cause local frost to damage the wall.

Most self-insulating blocks are designed with through holes and full blind holes. Through holes are easy to leak grout during the masonry process, resulting in waste of building materials and reducing the thermal insulation performance of blocks; full blind hole bricks can avoid this problem and save construction costs. material, but the existence of blind holes causes thermal bridges in blocks
