Description

Exempt to tear open high-performance cement mortar template insulation regeneration concrete rectangular column and the practice

Technical field

The present invention relates to one and exempt to tear open high-performance cement mortar template insulation regeneration concrete rectangular column and the practice, belong to technical field of structural engineering.

Background technology

Along with the develop rapidly of productivity, energy-output ratio is more and more higher, and China's demand for energy increases with annual 2% ratio, and these energy nearly 30% consume on building.According to statistics, to the end of the year in 2000, oneself reached 76.6 hundred million square metres (wherein 44.1 hundred million square metres, houses) national existing building area cities and towns, wherein can reach approximately 1.8 hundred million square metres of heating and energy saving design standard, only accounted for 2.3% of urban house area.The whole nation still has the cities and towns heating floor space of more than 40 hundred million square metres to need transformation, adds the building construction in public building, industrial construction and rural area, and the whole nation has the existing building of more than 270 hundred million square metres need to carry out reducing energy consumption.Particularly at present China in a large number the public building with central air conditioner system be also energy for building rich and influential family, this class building approximately has 30%~50% huge energy-saving potential in space enclosing structure and heating air-conditioner system aspects.As an energy consumption big country, the importance of energy conservation revealed to come at every field of China convexity already.Enter 21st century, along with the implementation of the relevant policies such as reform and building energy conservation of China's building thermal insulation material, develop new heat insulating material and energy-saving residence structural system has become one of top priority of engineering circles.

Along with the fast development of civil engineering, China will produce a large amount of building wastes every year, and wherein discarded concrete just accounts for building waste 30%~40%.So the discarded concrete of flood tide, except disposal cost is surprising, also needs to take a large amount of vacant lot and deposits, contaminated environment, and waste is ploughed, and becomes large public hazards in city, and the environmental problem causing is thus also very outstanding.Taking China as example, if need to take up an area two mu by 10,000 tons of building wastes calculates, the discarded concrete of annual 18~2,400,000,000 tons just need to take 36~4,800,000,000 mu of soils, this makes the matter worse to the present situation of the original land shortage of China beyond doubt, the suburbs, a lot of big and medium-sized cities such as China Beijing, Shanghai is difficult to find abandons the place of burying, and this situation will be increasingly severe.

Traditional steel concrete rod structure need to be made wooden form in building, not only waste resource but also improved construction costs, construction is got up also comparatively inconvenient, simultaneously, tradition reinforced concrete post heat-insulating property is generally poor, and mostly inside builds is ordinary concrete, cannot accomplish environmental protection.Based on this, the present invention proposes a kind of simple environmental protection, be easy to construction, with permanent exempt to tear open high-performance cement mortar template replace conventional template, the green energy conservation load-bearing pillar of cast-in-situ thermal-insulated regeneration concrete, than traditional concrete bearing post, its durability and bearing capacity increase, mortar template exempts to tear open simultaneously, globality and the anti-seismic performance of structure are improved, meanwhile, the insulation regeneration concrete of employing not only has good heat-insulating property but also can accomplish environmental protection, is highly suitable for new structural system low, multistory building.

Summary of the invention

The object of the present invention is to provide a kind of there is the durable advantage such as integrated of simple structure, cheap, easy construction, green energy conservation exempt to tear open high-performance cement mortar template insulation regeneration concrete rectangular column and the practice, not good to effectively solving conventional concrete post heat-insulating property, poor durability, cannot accomplish the problems such as environmental protection.

For achieving the above object, the technical solution used in the present invention is that one exempts to tear open high-performance cement mortar template insulation regeneration concrete rectangular column and the practice, of the present inventionly exempt to tear open high-performance cement mortar template insulation regeneration concrete rectangular column, this rectangular column comprises high-performance cement Mortar Plates, high Polymer Mortar, cage of reinforcement, regeneration concrete, vitrifying microballon, angle iron connecting piece.

Particularly, high-performance silt particle pulpboard can be processed into corresponding modulus, and as 300,600,900mm, thickness is 20~25mm.What mortar adopted is High Performance Mortar, inside has steel wire to gather net as cage of reinforcement, adopting dither to carry out fine and closely woven reality vibrates, net is effective to bond to ensure to gather High Performance Mortar with steel wire, greatly improved compactness and the intensity of wire mesh mortar plate, theory can reach C40~C50 strength grade of concrete; In the time of processing high-performance cement Mortar Plates, the outside of one side as formwork for placing put down in a throwing, the inner face that coarse one side is formwork for placing, thereby the insulation regeneration concrete that effectively raising is built and the bonding of high-performance cement Mortar Plates.

High Polymer Mortar provides reliable bonding for wire mesh mortar plate, adhesive-hardening fast simultaneously, thus overcoming the problem of setting up of wire mesh mortar template, mortar smearing thickness should not exceed 5~8mm.

Longitudinal reinforcement in described cage of reinforcement adopts HRB335 level or HRB400 grade reinforcing steel, and diameter is 12mm~14mm; Stirrup adopts HPB300 grade reinforcing steel, and stirrup diameter is 8mm~10mm, stirrup spacing 150mm.

Regeneration concrete is the concrete of preparing according to the replacement situation of different thicknesses aggregate, by discarded concrete disintegrating, cleaning and sieve classification and by a certain percentage mutually proportioning form, be divided into coarse aggregate and replace regeneration concrete and fines replacement concrete, mainly replace with coarse aggregate, replacement rate is 30%~50%, and fines replacement rate is no more than 10%.

Vitrifying microballon is a kind of continuous vitrifying confining surface, the irregular orbicule particle of inner complete porous hollow structure simultaneously, and it has light weight, insulation, ageing-resistant feature.The diameter of the vitrifying microballon of selecting is 1.5~2.0mm.Vitrifying microballon and regeneration concrete combination have just formed novel heat insulation regeneration concrete.

Angle iron connecting piece is selected small-sized equal leg angle, and being of a size of ∠ 30 × 30 × 3(hem width is the thick 3mm of being in 30mm, limit), the connection for stiffened wire lath Mortar Plates in bending place, horizontal arrangement spacing is 250~300mm, vertical spacing is 300~400mm.

Compared with prior art, the present invention has following beneficial effect.

The present invention exempts to tear open high-performance cement mortar template insulation regeneration concrete rectangular column and is applicable to low, multilayer novel building system.The novel heat insulation regeneration concrete adopting has not only improved the heat-insulating property of structure but also can accomplish green regenerating, heat-insulating property can improve 20%, meanwhile, high-newly can reinforced cement-mortar board there is good durability and intensity, not only can be in order to avoid have torn but also improved globality and the durability of structure open as exterior sheathing.
