Description

A kind of 31 hole sound-insulating and heat-insulating self-heat preserving sintering hollow bricks

Technical field

The utility model belongs to materials for wall field, relates to a kind of body of wall brick, specifically a kind of hollow brick, particularly sintered hollow block, and this brick has sound insulation, heat insulation, heat insulation function.

Background technology

In this year, along with walling innovation and the popularization of building energy conservation and the development of highrise building, Lightweight aggregate concrete small hollow block development is quite fast, occupies an leading position in materials for wall.

The application of Normal concrete small hollow block in multilayer load bearing construction and little high-rise arrangement of reinforcement building obtains tremendous development, and has breakthrough.Non-bearing building block, particularly light aggregate hollow block maintains sustained and rapid growth.

According to further power conservation requirement, in recent years, China produces the hollow fragment of brick of sintered heat insulating that voidage is 31%, adopt concrete, light aggregate concrete or Aerated Concrete, and utilize sand, various industrial waste, flyash, gangue etc. to make the building block of clinker-free cement concrete or Autoclaved limesand brick, fly ash silicate brick, building block etc. to have larger development in China, annual increasing rate is about 20%.Therefore, building block, as the main alternative materials of loam brick, is functionally better than loam brick at some, and development prospect is very good.

But Normal concrete small hollow block exists very important problem in development, mainly building block block-type is unreasonable.The little building block of thick three round of current employing 290mm, hole is wide at about 50mm.But some producers, in order to save material, reducing quality, ignoring heat-insulating property and require or ignore technical requirements, the little building block of the wide 31mm of thick for 231mm three round being changed into single row of holes hole wide is 180mm, builds heat-insulating property and obviously declines, do not reach thermal technology's requirement.

Along with the policy of national building energy conservation is put into effect, Surgery therapy compound concrete block wall will speed up development.Frame construction, shear wall structure building increase sharply, non-bearing building block, and particularly building small-sized hollow building block will make further progress.What require raising house sound-insulation capability accounts for 35.15%, ranks first.Visible improve house, office acoustic environment very important.At present, its sound insulation factor of party wall of a lot of light-duty wall composition only has 30dB, and this and the requirement of people to environment fall far short.Therefore, sound insulation factor >=50dB, reaching the small-sized hollow building block that " green building material " require will obtain Rapid Popularization.

For solving the problems of the technologies described above, inventor have developed a kind of heat insulation Self-thermal-insulation hollow brick, comprise brick body and be arranged at the several exhausting holes in brick body, every exhausting hole comprises two or more through hole, adjacent two exhausting holes shift to install, and are positioned at the twice existing for itself and every exhausting hole size of that exhausting hole of thematic center line.

Inventor, in the process implementing the invention, has summed up the measure promoting building-block thermal property and has comprised following direction:

1, starting components and match ratio is adjusted; The sintered hollow building block of same specification and identical pass, hole arrangement and voidage, its thermal insulation combination property improves with the reduction of density.By adjusting raw-material match ratio, as being set between 50%-75% by the ratio of gangue, improving raw-material plasticity, improving raw-material fineness.

2, structure optimization and innovation hole arrangement mode.Although aforementioned heat insulation Self-thermal-insulation hollow brick achieves rapid progress at aspect of performances such as sound insulation, heat insulation, insulations, also do not reach ideal effect.Meanwhile, the setting of pass structure and arrangement mode thereof is also closely bound up with the application life of building block.

Can the adhesive property of gripping properties and block surfaces and construction slurry for what improve building block, there is a need to improve the external surface of building block.

In addition, the size of usual hollow brick is comparatively large, comparatively requires great effort, can increase the degree of fatigue of construction worker to a certain extent when construction worker builds a wall when crawl hollow brick.
