Description
Technical field
The present invention relates to a kind of structure material, be specifically related to a kind of building block brick.
Background technology
Fired common brick, be commonly called as " common brick ", having another name called " solid clay brick ", is widely used a kind of material in the building construction, because its production technique is simple, technology maturation, draw materials conveniently, cheap, adiabatic preferably, fire-resistant and weather resistance are arranged, the history in existing thousands of years of use in China still is applied so far.But, in sintering procedure, also there are high consumption, high pollution situation, the production serious threat land resources and the ecotope of common brick because of traditional common brick has caused great destruction to land resources in the process of drawing materials.In June, 2005, the General Office of the State Council issue " about further propelling materials for wall more novel species promote the notice of energy saving building ", require from the end of the year 2010, all cities ban use of solid clay brick.Along with carrying out of " prohibiting real " work comprehensively, common brick will progressively step down from the stage of history.
Fired common brick exists following main drawback and deficiency:
1, land resources consumption is big:
With the Heilongjiang Province is example, by the end of the year 2006, more than 1200 families of total solid clay brick factory of the whole province, 8,500,000,000 of year production solid clay bricks, the annual brick field nearly ten thousand mu of good farmlands of borrowing earth and occupying land, this does not also comprise annual newly-built, enlarging clay brick tile kiln, ruin the shared soil of phenomenon such as bake bricks, field.
2, the big pollution of power consumption weighs:
With the Heilongjiang Province is example, year is produced 8,500,000,000 of clay common bricks, bake bricks in year and consume 700,000 tons of standard coals of coal, 330,000 tons of discharge of noxious gases, along with rapid growth of economy and population increase, if continue to use traditional clay brick as materials for wall, the contradiction of china natural resources and energy relative deficiency is more outstanding with making, and environmental stress increases day by day.
3, piece is little of great:
Existing common brick is a rectangular parallelepiped, and its standard size is 240mm * 115mm * 53mm, adds the thickness of building by laying bricks or stones with mortar joint, and then 4 long 8 bricks of brick are wide, and 16 thick difference of brick are 1m just, so every 1m
3Brick structures need be used 512 of bricks.The weight of common brick monolithic generally is between 2.1kg to 2.5kg before the suction, and its unit weight reaches 1600kg/m
3～1800kg/m
3
4, heat-insulating property is poor:
The sintered clay common brick, dry density 1600～1800kg/m
3, thermal conductivity [w/cmk] 0.81, so the wall thickness that builds a house is not incubated, winter is cold, summer, hear rate can be big.
5, increase the building complex cost:
Consider the unit weight situation of unselected clay common brick,, certainly will increase the structure reinforcing bars consumption, promote the architectural complex cost increasing the expense of ground, basis, beam column, plate as considering from design.
Summary of the invention
The consumption of unselected clay common brick land resources is big in order to solve, power consumption big pollute heavy, piece little from great, heat-insulating property is poor, increase the deficiency of building complex cost, the invention provides a kind of bulking brick of energy-conserving and environment-protective, it has lightweight, hard, insulation, fire prevention, nontoxic, competent advantage, is a kind of ideal energy saving building building block brick.
Bulking brick of the present invention can obtain according to following two kinds of methods:
Method one: a, be raw material with the silt particle rock, crushing and screening; B, enter in the high temperature rotary oven and to carry out expandedly towards the oxygen pressurization then, wherein at 3～8MPa, adjust humidity is 0.5～0.8% to Control for Kiln Temperature at 1200～1400 ℃, pressure, carries out secondary heating after producing extruded body, and controlled temperature is 1400～1600 ℃; C, last mechanical presses moulding obtain bulking brick.
Method two: a, be main raw material with the silt particle rock, crushing and screening; B, enter in the high temperature rotary oven and to carry out expanded then towards the oxygen pressurization, wherein at 3～8MPa, adjust humidity is 0.5～0.8% to Control for Kiln Temperature at 1200～1400 ℃, pressure, carries out secondary heating after producing extruded body, controlled temperature is 1400～1600 ℃, obtains extruded body; C, extruded body mechanical disintegration granulating, mix with cement, flyash, concrete additive then, wherein the weight percent of each raw material is: extruded body 30～50%, cement 15～25%, flyash 20～40%, concrete additive 5～15%, after mechanical stirring adds water, be delivered to feed bin, carry out extrusion molding, obtain bulking brick.
Bulking brick of the present invention has following advantage:
1, saves land:, energy-conservation: be 2.8 times that the clay common brick is incubated, accomplish cool in summer and warm in winter without clay and good farmland.
2, abundant raw materials, technology is simple, technology maturation, examination criteria complete (construction work inspection department and technical supervision department can both detect).
3, bulking brick, lightweight, high-strength, reduce the building comprehensive cost, as considering, can reduce foundation beam column, plate expense from design, reduce the structure reinforcing bars consumption, save masonry mortar 50%～60%, save manually 40%, reduce the building total cost.
4, easy construction is built by laying bricks or stones quick.This brick is in light weight, block big (1 standard square volume is equivalent to 4.5 blocks of clay common brick), and to compare the speed of building by laying bricks or stones fast with the clay common brick, shortens the construction period, improves operating efficiency 30%.
5, usable floor area increases, and owing to lightweight, insulation, high-strength, multi-functional, thickness of wall body can corresponding attenuate.Characteristics such as increase the effective usable floor area of buildings, floor plan is decorated wide flexibly, because it be a solid brick, has and can dig, and punches, the ingot nail, and is non-friable.
6, the contrast of unselected clay common brick and bulking brick performance perameter is as shown in table 1.
