Description
Technical field
The invention belongs to building material technical field, be specifically related to a kind of set of molds for making concrete slit floor
Part and application thereof.
Background technology
Slit floor is as the term suggests carrying apertured floor, metal, plastics, concrete etc. to may serve to manufacture micro-exactly
Seam floor.Compared with other material, concrete slit floor have cost relatively low, solid durable, corrosion-resistant, be unlikely to deform, easily
Numerous advantages such as clean and heat conductivity is little.Therefore, current concrete slit floor is the most necessarily applied in China, as its
The application of modernized pig raising field.
But, there is a lot of pitted skin in the concrete slit floor surface produced, have impact on finished appearance mostly.At coagulation
In the forming process on soil slit floor, due to the aspect such as material, construction technology, frequently can lead to floor surface and produce one
A little bubbles, particularly commerical ready-mixed concrete are more readily formed bubble.There is a lot of bubble in the concrete surface just poured, directly leads
After causing hardening, there are many tiny pit-holes in floor surface, thus forms surface pitted skin.
The existence of concrete surface pitted skin, on the one hand reduces the decay resistance on floor, has had a strong impact on concrete micro-
The durability on seam floor；On the other hand decreasing the effective thickness of cover to reinforcement, the carbonization accelerating concrete surface is entered
Journey, reduces the surface quality on slit floor.It is thus desirable to the floor surface that pitted skin is more to be carried out after-treatment, spend work
Material, adds construction cost.
