Description
(1) technical field
It is especially a kind of to be filled with modified polyphenyl particle concrete the present invention relates to a kind of concrete structure outer for participating in stress
Structure outer, belong to buildings in general construction field.
(2) background technology
In green building, higher and higher requirement is proposed to the heat-insulating property of structure outer.Outside traditional structure
In wall heat preservation technology, common way is that insulation material (typically polyphenyl bubble is first installed in exterior wall concrete structure outer surface
Foam), overcoat is then done outside insulation material again.The defects of this way is exactly the combination appearance of insulation material and body structure surface
Easily potential safety hazard be present, year in and year out after material aging, insulation material may come off from structure to cause casualties；In addition,
If overcoat thickness is no more than 50mm, the fire protecting performance of wall is not up to standard.It is corresponding, also exterior wall insulating temperature technique, i.e., outside
The inner side paste heat-preserving material of wall, then smears one layer of mortar with anticracking material on insulation material.But this way is still deposited
In the defects of not up to standard, also the hanging poor performance of interior wall of preventing fires.
In recent years, the way that insulation material is filled in structure outer, i.e., the pre-buried solid state in wall are risen again
The insulation materials such as polyphenyl foam plate, then the both sides assembling reinforcement in insulation material, casting concrete.This kind of thermal insulation structure it is excellent
Point is that the durability, security and fire line of structure are good, and shortcoming is that construction bothers, in the polyphenyl foam plate and wall of solid state
Various pipelines, embedded part, the matching of hole and different walls shapes are poor, and polyphenyl foam plate install it is time-consuming, take a lot of work.
Foam concrete due to there is many cavitys in concrete, although therefore its intensity it is relatively low, insulation and sound insulation
Performance is good, can turn into a kind of preferably structure outer insulation material.
It is air entrained concrete first in foam concrete, its principle is in inside concrete with method physically or chemically
Produce many bubbles.But if bubble ambient pressure is excessive (concrete thickness is larger) in air entrained concrete, bubble volume is obvious
Becoming small porosity significantly reduces.Therefore air entrained concrete has larger cost advantage in ground construction, but wall is once when building a wall
Property forming height can not excessive (generally height be no more than 1m), if wall need to be poured repeatedly, though material cost increase is seldom,
Artificial and machine cost is multiplied.
Polyphenyl foam is one kind that performance is more prominent in existing insulation material, and the thermal conductivity factor of polyphenyl foam is about
0.39W/ (m.k), less than most of insulation material.The presence of polybenzene foamed concrete also has the long period, usually will
After recovery polystyrene foam plastics is smashed, mixed and stirred together with cement mortar, light-weight brick or external thermal insulation bed course is made.But this
The feature of kind polybenzene foamed concrete exactly can not vibrate or can not vibrate for a long time, and otherwise granular polystyrene just floats, heavy aggregate
Sink, concrete isolates.
2016, Chen Jingbo was proposed " the resistance to preparation method for freezing granules of polystyrene concrete of lightweight self-closing's antiseepage "
(CN106007580A), its principle is to change the physical property of granular polystyrene using additive, after stirring, is remained to even if vibrating
Ensure that granular polystyrene is evenly distributed in cement slurry.Since CN106007580A is applied, good technology effect has been generated
Fruit, still, it is about 14kg/m that the defects of it is present, which seeks to ask the natural deposited dry density of granular polystyrene,3So that polystyrene
Particle concrete cost is higher.
In this case, make full use of the characteristic of polyphenyl foam, develop a kind of good heat insulating, from heavy and light, it is easy for construction,
The low tool of cost has the concrete structure outer of sound insulation function concurrently, it has also become urgent problem in current building field.
