Abstract
The invention discloses a sandwich self-insulation foam concrete block. The body of the block is composed of outer walls (1) and inner walls (2), wherein the outer walls and the inner walls enclose a plurality of sandwich cavities; and inorganic light-body insulation materials are added to the cavities to form sandwich layers. Being self-insulated, the block can reduce the total insulation cost of buildings by about 30%, has low heat conductivity, can achieve the technical requirement of 65% of building energy efficiency and has high strength and good bending resistance. The major raw materials of the block are flyash and foam concrete, are totally inorganic materials, are fireproof, refractory and light, have low density and are conductive to reducing dead weight of the buildings. As the periphery of the product is smoother, the manhour is saved during construction.
Description
Technical field the present invention relates to a kind of constructional materials, is a kind of heat preservation building block specifically.
The background technology building heat preservation is the key subjects of current energy-saving and emission-reduction and sustainable development from now on, its developing direction is a self-heat conserving, but because various self-heat conserving building block products are undesirable, what have is structural bad, the own complex structure cost height that has, common building block is owing to there is the space, and construction is inconvenient; Cause most so far buildings still to adopt the secondary insulation passively, heat insulating materials such as subsides or plug-in plastic foamboard outside promptly after building is built up, carrying out again.Great in constructing amount, expend heat insulating material, building costs height in addition.Some heat insulating material is inflammable, causes disaster hidden-trouble.The building block of the building self-heat conserving that development structure, heat insulating ability are all good is a current urgency problem to be solved.
Summary of the invention the object of the present invention is to provide a kind of sandwich self-insulation foam concrete block, it be structural meterials be again heat insulating material, energy-saving and environmental protection reduce building costs.
Technical scheme of the present invention is as follows:
The main body of this building block is made of outer wall and inwall, and outer wall and inwall surround a plurality of sandwich chambeies, adds the inorganic heat preservation light material in this chamber and constitutes sandwich layer.
Above-mentioned outer wall front end face is established tenon, and rear end face is established groove, and tenon is corresponding with groove location, size shape cooperates, and tenon and groove part are done fillet.
Above-mentioned outer wall and inwall are thickeied gradually by end face to bottom surface.
The above-mentioned sandwich chamber interior angle that outer wall and inwall surrounded is a fillet.
Above-mentioned inorganic heat preservation light material is foam concrete or foamed pearlite.
The invention has the advantages that: 1,, can significantly reduce the cost of building heat preservation because this building block is a self-heat conserving.The cost height is one of major reason that restricts at present the building energy conservation development, and it is the structural meterials of building, is again heat insulating material, and this building block not only can replace common brick but also can replace being incubated the benzene plate, therefore, can reduce building heat preservation total cost about 30%.
2, coefficient of thermal conductivity is low, the heat insulating ability excellence.This building block product sandwich layer is the insulation main body, and coefficient of thermal conductivity is 0.07w/mk, and main body is auxiliary insulation, and coefficient of thermal conductivity is 0.19w/mk, can reach the technical requirements of building energy conservation 65%.
3, intensity height, anti-bending strength is good.The compressive strength of this product sandwich layer is 0.15MPa, and the compressive strength of building block main body is 0.4MPa, and the entire compression strength character is good.
4, this product primary raw material is flyash and foam concrete, is the full-inorganic material, fire prevention, fire-resistant, and refractory temperature can reach more than 1000 ℃, and fire endurance surpassed 1.5 hours fire protection requirement greater than 2 hours.And ageing-resistant, can with the same life-span of building, do not produce any hazardous substances, discarded back reproducible utilization, the energy that consumes during production only for 1/10 of foamed plastics, can replace foamed plastics.
5, lightweight, density are low, favourable reduction structural weight per square meter.The bulk density of ordinary concrete is 2400kg/m
3This product sandwich layer bulk density 160--200kg/m
3, main volume density 600kg/m
3
6, save man-hour because the peripheral smoother of product, after this concrete block masonry with common building block relatively, remove the operation of smearing mortar levelling again from, promptly the saving working hour is saved a part of material again.Comparing with building-block, because there is the core of adding filler inside own, is smooth, more convenient when construction, has saved a large amount of man-hours.
7, water absorption rate is low, and frost resistance is good, and antibiotic anti-corrosion property is good, applied range.Therefore the gas concrete water absorption rate can not be used for high and cold high humidity area up to 40%.And this building block is because the rate of closed hole height, and its water absorption rate is 19%, is lower than 20%, and frost resistance is good, and after 15 freeze thawing circulation, its intensity reduces less than 10%, meets technical requirements, can be used for severe cold area.This building block is suitable for using under the condition of high humility or humidity conversion often because high closed pore can not pass through mould.
8, has good sound insulation.The sound insulation excellence of this product, according to Preliminary Determination, its sound insulation capabilities is about about 48 decibels.
This building block meets national standard through the check of national building materials industry room construction material quality supervision and test test center.
This block performance of table 1 index table
