Abstract
The utility model discloses an autoclaved aerated concrete composite heat insulation block. The outer wall of the block and the block are made of autoclaved aerated concrete materials, and a hole formed by the outer wall of the block and a block rib is filled with heat prevention and insulation fillers twice. The block utilizes the aerated concrete materials as the raw materials, and adopts a preinstalled mould core structure. After slurry pouring is completed, the mould core is extracted to cause a block green body to form a hollow structure in a forming process, and the porosity of the hollow structure can reach ranging from 30 percent to 70 percent. After autoclave curing carried out on the green body which has the hollow structure is completed, light weight heat prevention and insulation materials are filled twice to reduce the product volume weight and enhance the heat prevention and insulation performance of the materials, and the construction is simple. According to the application requirements, absolutely dried volume weight can be regulated in the range of 300 kg/m3 to 600 kg/m3, and the heat transfer coefficient can reach below 0.5 W/m2.K to cause a single wall body material to reach 65 percent of the state building energy conservation requirement. The autoclaved aerated concrete composite thermal insulation block has remarkable energy conservation effect, and can be widely applied to industries and civil building wall bodies.
Description
Technical field
The utility model belongs to the construction material technical field, is specifically related to a kind of steam pressurized concrete composite heat insulation building blocks.
Background technology
Show according to data, about 30% of present China building energy consumption account country energy consumption, building energy conservation becomes an important process of China's energy-saving and emission-reduction." public building energy-saving design standard " regulation of implementing on 07 01st, 2005, the city new building all should strictly be carried out the second step building energy conservation of building energy saving rate 50% and force standard code, metropolis with good conditionsi and severe cold, cold district can take the lead in carrying out according to the 3rd step of fractional energy savings 65% energy conservation standard, and actively promoting novel wall material is the important step that advances building energy conservation.
Air-entrained concrete building block is better than other traditional construction material as a kind of novel wall material on thermal and insulating performance.At present, domestic air-entrained concrete building block is solid article, and in Application in Building, the single body of wall coefficient of thermal conductivity of stock size is generally 0.18～0.22W/m.K, and insulation, effect of heat insulation is still not ideal enough, can not reach national energy conservation criteria fully.
Existing solid air-entrained concrete building block wants to satisfy national energy conservation standard, and the one, increase block thickness, certainly will cause cost to increase like this, reduce the building usable floor area; The 2nd, cause difficulty increase in the practice of construction, cost raising, and be easy to generate cracking between composite material and the body of wall at the compound again one deck heat preserving and insulating material in aerated concrete wall outside, poor durability influences result of use; The 3rd, reduce goods unit weight, reduce heat transfer efficiency, but because goods unit weight reduces, its intensity is relatively poor, the scope of application is restricted, and generally can only be used for thermal insulation usefulness such as roofing, and is higher to raw material and technological requirement simultaneously, domestic general enterprise is difficult to reach technological requirement, and production application is subjected to certain limitation.
Summary of the invention
The purpose of this utility model is to provide a kind of can strengthen the air-entrained concrete building block heat preservation and insulation, make single body of wall reach the national standard of fractional energy savings 65%, the steam pressurized concrete composite heat insulation building blocks that reduces goods unit weight simultaneously and can under common process and raw material condition, produce.
For achieving the above object, the technical scheme taked of the utility model is:
A kind of steam pressurized concrete composite heat insulation building blocks, it is made up of building block outer wall, building block rib and thermal insulation filler, it is characterized in that: described building block outer wall and building block adopt the steam-pressing aero-concrete material to make, and secondary is filled the thermal insulation filler in the hole that building block outer wall and building block rib constitute.
The above-mentioned steam pressurized concrete composite heat insulation building blocks that the utility model provides, utilize the gas concrete material to be raw material, adopt default mold insert structure, extract core rod after slip casting is finished, make the building block base substrate in forming process, form hollow structure, the void content of hollow structure can reach 30%～70%, after the base substrate of finishing hollow structure carried out steam press maintenance again, secondary light filling heat preserving and insulating material reached and reduces goods unit weight, improve the thermal and insulating performance of material, and easy construction.Can be according to instructions for use over dry unit weight at 300～600kg/m
3Adjust in the scope, heat-insulating property also can be adjusted by increase and decrease building block inner thermal insulating layer thickness, and thermal transmittance can reach 0.5W/m
2.K below, make reach the building energy conservation requirement of country 65% single one step of materials for wall, energy-saving effect is remarkable, and more traditional gas concrete entity building block energy-saving effect improves more than 30%, can be widely used in industry and civilian construction body of wall.
Through the check of constructional materials product quality supervision and inspection station, Gansu Province, the conclusion that draws is: " according to JGJ 132-2001 " heating Residential Buildings Energy test stone ", the masonry thermal resistance of steam pressurized concrete composite heat insulation building blocks is 2.17m
2.K/W (the conversion thermal transmittance is 0.46W/m
2.K) "." through check, building block accord with Q/ZYQTJC01-2007 " steam pressurized concrete composite heat insulation building blocks " standard.Radionuclide is limited the quantity of and is met requirement among the GB 6566-2001 " the radioactive material nucleic is limited the quantity of ", and its production and marketing and the scope of application are unrestricted.”
