Description
Affiliated technical field
The present invention relates to a kind of materials for wall, especially a kind of self-heat conserving ceramsite concrete hollow block that is used for non-bearing wall body.
Background technology
Along with the issuing and implementation of country and each department joint soil, " prohibiting real " policy and energy-conservation new standard, air-entrained concrete building block is applied in some areas, have moisture absorption be afraid of tide, intensity difference, easy to crack, facing easily comes off, the shortcoming of the complexity of constructing.
At present, the multi-story masonry structure is adopted in China's urban architecture more, and its exterior wall must satisfy corresponding building energy-saving standard.Body of wall realizes that the approach of building energy conservation mainly contains the gentle external wall outer insulation of exterior wall insulating.Exterior wall internal insulation exists influences pipelining and interior decoration progress, take problems such as hanging the thing difficulty on careat, the wall; When then there is mounting cost in external wall outer insulation, take problems such as leading duration, cost height.A kind of appearance that replaces the novel energy-conserving insulating wall material of clay solid brick of market in urgent need.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of self-heat conserving ceramsite concrete hollow block that is used for non-bearing wall body, its light weight, and the intensity height, thermal conductivity is little, and cost is low, convenient and quick construction.
A kind of self-heat conserving ceramsite concrete hollow block is characterized in that: made by the material of following weight percent basically: haydite 50～70%, flyash 20～30%, cement 6～12%; Described haydite is made up of 55～70% broken former haydite and 30～45% former haydite; The former haydite of described fragmentation is to be formed through crusher in crushing by former haydite;
Its manufacturing process steps is as follows:
(1) gets the raw materials ready: take by weighing former haydite, flyash, broken former haydite and cement according to the above ratio;
(2) stirring that feeds intake: add above-mentioned material in proportion, use forced concrete mixer to add water and fully stir with conventional water consumption;
(3) compression-vibration shaping: the mass transport that mixes to building block mould, is compressed material with the compression-vibration shaping machine while vibrating, obtain the building block work in-process;
(4) demoulding maintenance: conventional method demoulding maintenance.
Energy-saving principle of the present invention: new covil construction energy-saving design standard code the heat transfer coefficient limit value of different areas residential architecture each several part building enclosures.Product of the present invention can satisfy the energy-conservation requirement of non-severe cold area external wall.Product of the present invention adopts broken haydite to mix with former haydite, makes auxiliary material with flyash and fills the space, makes gelling material with cement.With combining of cement, broken former haydite is more better than former haydite, and building block can obtain better intensity.Raw material all passes through high-temperature firing, does not contain raw material, and flame retardant properties is good.
A kind of concrete structure is, comprises the quadrate body, is provided with three round holes between the inner face of described body and the outer face, round hole, middle round hole and efflux hole in described three round holes comprise, and interior round hole and to efflux hole be blind hole, middle round hole is a through hole.The long-width ratio in round hole is not more than 2 in being designed to, and the brittle rupture ability is stronger under the whole opposing of the building block load.Half-blindness hole face can be saved the mortar consumption as building the shop slurry by laying bricks or stones, and the shop is smeared mortar and is difficult for falling in the building block hole, has reduced wall weight.Building block is provided with three rounds and understands thoroughly to the heat-insulating sound-insulating effect.To lead directly to rib and stagger, and stop and lead directly to, separate Cooling and Heat Source as far as possible, reach the heat preservation energy-saving requirement.
A kind of improvement is, the both sides of described body be provided with pair of straight groove mouth in conjunction with end face, the bearing of trend of described notch is consistent with the hole bearing of trend.When building by laying bricks or stones, do not go up mortar in the notch, the assembly in twos of the notch of adjacent block forms two assembly holes in the building block both sides, and purpose is to stop that to build the seam Cooling and Heat Source by laying bricks or stones straight-through, the whole pass structure that constitutes " three row's octals ", and voidage reaches 40%.
The tier building that product of the present invention is suitable for the cold non-severe cold area of Xia Redong uses, and the present invention has following advantage:
1, product of the present invention has the self-heat conserving characteristics, and energy-saving effect is remarkable.Product of the present invention is the heat preservation energy-saving walling of high comprehensive performance, detects through Sichuan Province's construction engineering quality inspection center, and salient features: (1) strength grade: the self-heat conserving ceramsite concrete hollow block can reach MU2.5, MU3.5, MU5.0; (2) thermal property: heat transfer coefficient reaches＜1.30W/ (m
2K), heat-insulating property meets the energy-conservation requirement of Sichuan regional architecture.(3) other performance: meet GBT15229-2002 " lightweight small size hollow concrete blocks ".
2, product light weight of the present invention, the ultimate compression strength height, security is better.Product unit weight of the present invention is lower than 800kg/m
3, lower more than 12% than shale hollow brick.Can arbitrarily hole the fixing various suspension members of the long setscrew of 6cm are installed, can not come off, become flexible.Also be convenient to install embedding pipe fittings, can arbitrarily cut,, all can not damage the structure and the performance of full brick, and make things convenient for shutoff even slot in both sides on same brick.Because haydite is the inert material, coefficient of softening is greater than 0.85, and water-fast and weather resistance height is so body of wall is safe.
3, its brick body is bigger, has accelerated construction speed, has saved the consumption of mortar material.Its face of plastering is greater than the shale hollow brick, and the performance of anti-" ooze, leak, split " is better, can not cause hollowing, cracking phenomena.Thin mortar joint both can improve mechanical property of masonry, can reduce the mortar consumption again and reduced cost.Every cube of body of wall of product of the present invention is only used masonry mortar 0.3m
3, and the shale hollow brick when building by laying bricks or stones every cubic metre of body of wall need use mortar 0.7m
3
4, product of the present invention does not need exterior wall is incubated processing, has saved engineering cost.Compare with the shale hollow brick, with 50 yuan/m
2Wall thermal insulating calculates, and product of the present invention can be saved inside and outside 380 yuan/m of heat insulating work expense
3About (containing the expense of saving masonry mortar).
5, product sound-proofing properties of the present invention is good, and its sound absorption coefficient is 0.53-0.88, needing to be suitable for the engineering of noise reduction to select for use.Also have the strong characteristics of acid resistance.
