Description
Technical field
The present invention relates to one kind is exempted to tear high-performance cement mortar template insulation regeneration concrete rectangular column and the practice open, belong to knot
Structure field of engineering technology.
Background technology
Developing rapidly with productivity, energy-output ratio more and more higher, China's demand for energy is with annual 2% ratio
Increase, and these energy about 30% consume on building.According to statistics, to the end of the year in 2000, national existing building area
Cities and towns oneself reach 76.6 hundred million square metres (wherein 44.1 hundred million square metres of houses), wherein can reach the pact of heating and energy saving design standard
1.8 hundred million square metres, only account for the 2.3% of urban house area.Still there are more than 40 hundred million square metres of cities and towns heating living space needs in the whole nation
Transformation, adds the building construction in public building, industrial building and rural area, and the whole nation has more than 270 hundred million square metres of existing building
Need to carry out reducing energy consumption.Public building with central air conditioner system is also energy for building rich and influential family in a large number for particularly current China,
This kind of building there are about 30%～50% huge energy-saving potential in building enclosure and heating air-conditioner system aspects.Big as an energy consumption
State, the importance of energy saving revealed to come in every field convexity of China already.Enter 21st century, with China's building
The implementation of the relevant policies such as the reform of insulation material and building energy conservation, the new insulation material of exploitation and energy-saving residence structural system are
Become one of top priority of engineering circles.
With the fast development of civil engineering, China will produce substantial amounts of building waste, wherein discarded concrete every year
Just account for building waste 30%～40%.The discarded concrete of such flood tide is in addition to processing cost is surprising in addition it is also necessary to take a large amount of
Vacant lot deposit, pollute environment, waste arable land, become big public hazards in city, and the environmental problem thus causing be also very prominent
Go out.Taking China as a example, if needing to take up an area two mu to calculate by 10,000 tons of building wastes, annual 18～2,400,000,000 tons of discarded concrete
Be accomplished by taking 36～4,800,000,000 mu of soils, this give the original land shortage of China present situation make the matter worse beyond doubt, China Beijing, on
A lot of big and medium-sized cities suburbs such as sea is difficult to find abandons the place buried, and this situation will be increasingly severe.
Traditional armored concrete rod structure needs to make plank sheathing when pouring, and had not only wasted resource but also had improve
Construction costs, it is also more inconvenient that construction is got up, and meanwhile, conventional steel bar concrete post heat-insulating property is generally poor, and mostly interior
What portion poured is normal concrete it is impossible to accomplish environmental protection.Based on this, the present invention propose a kind of simple and environmentally-friendly it is easy to apply
Work, replaces conventional template with permanently exempting to tear high-performance cement mortar template open, the green energy conservation of cast-in-situ thermal-insulated regeneration concrete holds
Weight post, compared to traditional concrete bearing post, its durability and bearing capacity increase, and mortar template exempts to tear open simultaneously, improve
The globality of structure and anti-seismic performance, meanwhile, the insulation regeneration concrete of employing had not only had good heat-insulating property but also permissible
Accomplish environmental protection, be highly suitable for low, tier building new structural system.
Content of the invention
It is an object of the invention to provide one kind has simple structure, cheap, easy construction, green energy conservation durable
The exempting from of the advantages of body tears high-performance cement mortar template insulation regeneration concrete rectangular column and the practice open, to effectively solving tradition
Concrete column heat-insulating property is not good, and poor durability is it is impossible to the problems such as accomplish environmental protection.
For achieving the above object, the technical solution used in the present invention is exempted to tear the insulation of high-performance cement mortar template open again for one kind
Growing concrete rectangular column and the practice, of the present invention exempt to tear open high-performance cement mortar template insulation regeneration concrete rectangular column, should
Rectangular column includes high-performance cement Mortar Plates, high Polymer Mortar, framework of steel reinforcement, regeneration concrete, vitrifying microballon, Bolted angle connection
Part.
Specifically, high-performance silt particle pulpboard can be processed into corresponding modulus, such as 300,600,900mm, thickness is 20
～25mm.Mortar uses High Performance Mortar, and inside has steel wire to gather net as framework of steel reinforcement, is carried out using dither
Fine and closely woven reality is vibrated, and it is ensured that High Performance Mortar can be gathered with steel wire, net is effective to bond, and substantially increases wire mesh mortar plate
Packing and intensity, theory is up to c40～c50 strength grade of concrete；When processing high-performance cement Mortar Plates, only throw flat one
Face is the inner face of formwork for placing as the outside of formwork for placing, coarse one side, thus it is mixed to effectively improve the insulation regeneration pouring
Solidifying soil and the bonding of high-performance cement Mortar Plates.
High Polymer Mortar provides reliable bonding for wire mesh mortar plate, simultaneously can quick adhesive-hardening, thus gram
Take the problem of setting up of wire mesh mortar template, mortar smearing thickness is no more than 5～8mm.
Longitudinal reinforcement in described framework of steel reinforcement adopts hrb335 level or hrb400 level reinforcing bar, a diameter of 12mm～14mm；
Stirrup adopts hpb300 level reinforcing bar, and stirrup diameter is 8mm～10mm, stirrup spacing 150mm.
Regeneration concrete is the concrete prepared according to the replacement situation of different thicknesses aggregate, by discarded coagulation
Soil is broken, cleaning and sieve classification and by a certain percentage mutually proportioning form, be divided into coarse aggregate to replace regeneration concrete and thin bone
Material replaces concrete, is mainly replaced with coarse aggregate, and Replacement rate is 30%～50%, and fine aggregate Replacement rate is less than 10%.
Vitrifying microballon is a kind of continuous vitrifying confining surface, internal complete porous hollow structure is irregular simultaneously
Orbicule particle, it has the characteristics that light weight, insulation, ageing-resistant.From vitrifying microballon a diameter of 1.5～2.0mm.Glass
Glass microballon and regeneration concrete combination are the formation of novel heat insulation regeneration concrete.
Angle iron connecting piece selects small-sized equal leg angle, and a size of ∠ 30 × 30 × 3(hem width is 30mm, side is thick is 3mm), use
In the connection in bending place for the stiffened wire lath Mortar Plates, horizontally disposed spacing is 250～300mm, vertical spacing is 300～
400mm.
Compared with prior art, the present invention has the advantages that.
The present invention exempts to tear open high-performance cement mortar template insulation regeneration concrete rectangular column and is applied to low, multilayer novel building
System.Using novel heat insulation regeneration concrete not only improve the heat-insulating property of structure but also green regenerating, heat insulating ability can have been accomplished
Can improve 20%, meanwhile, high-new can have good durability and intensity by reinforced cement-mortar board, both can be in order to avoid tearing open as exterior sheathing
Improve globality and the durability of structure again.
