Description
Technical field:
The utility model relates to a kind of building walling, relates in particular to a kind of Autoclaved limesand brick, relates to a kind of steaming that belongs to new wall material more specifically and presses the sand-lime porous brick.
Technical background:
The invention of Autoclaved limesand brick and use the history in existing more than 100 year, its belongs to a kind of silicate product, is to be primary raw material with lime, sand, through feedstock production, compression moulding, steam press maintenance and a kind of materials for wall of making, be that a kind of raw material is more general, price is lower, the walling that is easy to get.And compression moulding, steaming pressuring curing process that sand adopts, production technology is very ripe, be a kind of walling of realizing that large-scale industrialization is produced, its regular size is 240 * 112 * 53mm, and is identical with common brick, easy to use, also approaching with traditional building construction method, in addition, qualified Autoclaved limesand brick has good physical and mechanical property, can satisfy the needs of existing building engineering, therefore be widely used for a long time.But along with progressively going deep into of China's walling reform, to the building wall material except that require to have insulation, the heat insulation key property, the characteristics that also should have intensity height, light weight, and Autoclaved limesand brick exists that density is big, block is little, coefficient of thermal conductivity is big, with shortcomings such as the ordinary mortar adhesion is relatively poor; Solid Autoclaved limesand brick density is about 1850Kg/m, in the walling of lightweight, it will exceed more than 30% than the density of common one hand tile brick, be three times of aerated-block brick density, because density is big, relative resource consumption is big, has increased the building deadweight, and the corresponding also increase of energy consumption, be unfavorable for building energy conservation.Thereby existing Autoclaved limesand brick has not met the direction of walling development, more can not adapt to the walling reform, building energy conservation, the national policy of saving resource.Recent years, many producers of this industry also once attempted producing steaming and pressed the sand-lime porous brick, but it is not because very reasonable to the design of hole size, void shape, cavity arrangement, make its porous brick density of producing, hole ratio, compressive strength all fail to reach the requirement of new wall material, thereby can not get applying.
Summary of the invention
The sand-lime porous brick is pressed in the steaming that the purpose of this utility model provides that a kind of density is low, compressive strength is big, single brick hole ratio reaches more than 25%, meet the new wall material requirement.
For realizing above purpose, sand-lime porous stone brick of the present utility model is to be primary raw material with lime, sand, through feedstock production, compression moulding, steam press maintenance forms, above-mentioned porous brick is a rectangular shape, on the surface that its longer wide-edge is formed, short transverse along the brick body offers the identical column hole in plurality of rows aperture, adjacent two round holes are laterally parallel, vertically stagger in each hole site, and the end face footpath of hole is wide be 26-32mm, and the center in outermost round hole is that center to center distance between 30-36mm, adjacent two holes is huge from being 48-60mm to the beeline at brick body edge.
Above-mentioned porous brick, the distance that vertically staggers in adjacent two round holes equal half with the adjacent two hole horizontal spacings of row.
For compressive strength and the rigidity that improves fragment of brick, the center in round hole and its center to center distance of arranging adjacent holes up and down are huge from being 38-46mm in the middle of being positioned at.
For brick can evenly be born and the compressive stress that distributes under pressure, also in order to alleviate the wearing and tearing of production mould, above-mentioned hole end face be shaped as circle.
In order to reduce the masonry mortar consumption, improve the snap-in force of mortar to brick, the hole of above-mentioned porous brick is a blind hole, blind bore end is 3-10mm to the distance on the surface that another is made up of longer wide-edge.
In order to make brick be easy to the demoulding in preparation process, the hole wall in above-mentioned porous brick cavity has certain gradient, makes the big up and small down tenon type of hole.
In order to improve porous brick and the caking property of building motar by laying bricks or stones, porous brick front and back and/or left and right sides sidewall are provided with shallow grooves along the direction of brick height degree.
The specification of above-mentioned porous brick is 240mm * 115mm * 115mm, and row's number of hole is 3, and the hole number is 11.
The specification of above-mentioned porous brick is 240mm * 175mm * 115mm, and row's number of hole is 5, and the hole number is 18.
Sand-lime porous brick of the present utility model has following advantage because the layout and the PASS DESIGN of hole are reasonable:
1, adopts the little structure in many rounds and aperture, make the density of brick be not more than 1350Kg/m
3, the density ratio with solid brick differs 500Kg/m
3, alleviate the weight of masonry self greatly, reduce the consumption of resource, reduce energy consumption.
2, adjacent hole between row and row is staggered, can not only evenly bear compressive stress, and can reduce heat bridge, makes it have good thermal property.
3, outer wall and the distance between Kong Yukong with porous brick is limited in certain scope, can make brick have good thermal property, can guarantee the mechanical property of brick again, and its compressive strength is reached more than the 10Mpa.
4, pass is selected circle, not only produces easily, and can alleviate the degree of wear of production mould, in addition, the more other forms of pass of circular port can guarantee that porous brick has bigger wall thickness and rib thick, can evenly bear and distributed stress under pressure, can not rupture at weakness.
5, adopt the blind hole design, build by laying bricks or stones in the slurry process of shop, help preventing that masonry mortar from bleeding in the hole in construction, can effectively save the mortar consumption, in addition, adopt hole to build by laying bricks or stones downwards, masonry mortar can be pressed as hole, will improve the snap-in force of mortar in the hole junction behind the mortar hardening brick.
6, the side of porous brick is provided with shallow grooves, can increase the adhesion of brick face and mortar in construction.
