The present invention relates to a kind of technology and mould thereof of making tightweight hollow bricks made of pottery clay, this brick is to utilize natural potter's clay, clay and industrial waste and water to provide the technical recipe mixing machinery to stir to become condiments, makes tightweight hollow bricks made of pottery clay through machine die extrusion modling, depanning, drying, roasting.This hollow brick has hole ratio height (55～65%), and dry density is light: (600～700kg/m
3), compression strength height (vertical core direction 100kg/cm
2More than, cross-drilled hole direction 25kg/cm
2More than), frost resistance is good, shrink little, low cost and other advantages.Be the infilled wall of a kind of high level, superelevation story frame structure, the lightweight wall body building material of partition wall.
Description
The present invention relates to a kind of technology and mould thereof of making the novel light wall body building material.
Wall body building material is a main construction material of building the house, has a large capacity and a wide range, and its weight accounts for more than 60% of building gross weight in architectural engineering.At present, China generally uses clay brick more than 80%, there is the minority place also to adopt structural clay tile (in the hole ratio 25%), because its manufacturing process falls behind, and with free-hand and auger type mechanical presses moulding, these two kinds of manufactures, labour intensity is big, the unit weight of brick is heavy, and raw material, fuel (coal), the energy () consume big, shortcomings such as production cost height.Building trade is used solid clay brick, because the heavy (1800kg/m of volume unit weight
3), the gross weight of increase building causes building foundation, frame beam column to increase raw material consumptions about 15% such as reinforcing bar, cement, sandstone, has not only increased the construction unit gross investment, and has brought component difficulty technically for foundation engineering, frame beam column.Structural clay tile is also adopted in the some places architectural engineering, because the still big (1300～1500kg/m of structural clay tile volume unit weight
3), hole ratio lower (in 25%), if as high level, the infilled wall of superelevation story frame structure, the wall body building material of partition wall, the cost gross investment is higher, the capital construction macro-control has been brought very big difficulty for country.
At the above-mentioned situation that exists, task of the present invention: provide a kind of hole ratio height, volume unit weight is light, the compression strength height, and good frost resistance is shunk for a short time, and cost is low, and reducing the construction unit gross investment is the manufacturing process and the mould thereof of the tightweight hollow bricks made of pottery clay of purpose.
A kind of manufacturing process of tightweight hollow bricks made of pottery clay, with granular raw material: potter's clay, coal ash, sawdust, land plaster mix with water, and it is characterized in that with potter's clay being that the light-weight hollow-brick source material mixture ratio (by weight percentage) of primary raw material is: potter's clay 25～50%(the best is 30～40%); Clay 15～35%(the best 20～28%); Coal ash 15～45%(the best is 20～30%); Sawdust 5～20%(the best is 8～15%); Land plaster 2～8%(the best is 4～6%), and add the mixed machinery of an amount of water and stir, and roller is become even closely knit denseness condiments to rolling bonding through machinery, through mechanical brick-making mould extrusion modling depanning, dry and roasting makes potter's clay thin-walled high-strength light hollow brick at 600～1000 ℃ (best 750～900 ℃) through the cooling kiln discharge again.
The capital equipment of finishing this technology is a brick-making mould, be used to make the structure of the brick-making mould of tightweight hollow bricks made of pottery clay: form by core rod, formwork and rear end joint three parts, it is characterized in that the core rod post (3) that has 1～4 die head evacuated panels (5) is welded on the core rod built-in beam (2), for adobe wall, the rib depanning speed of giving moulding are fully equated, be welded with longitudinal and transverse rib speed pilot beam (4) in the inboard of several core rod posts (3) and constitute core rod.Formwork is four blocks of trapezoidal hardwood plates of symmetry (9) on the core rod peripheral equipment, forming big actinal surface by the bottom of 4 blocks of trapezoidal hardwood plates (9) is fixed on the rear end joint (1), low profile is formed in the adobe exit in the last base of trapezoidal hardwood plate (9), and identical with the adobe size.
Four blocks of hardwood plates (9) are affixed to surround between trapezoidal formwork inwall and the die head evacuated panels (5) at a distance of 1～2cm; Die head evacuated panels (5) is each other at a distance of 0.8～1.5cm.
Lubricate any surface finish for making the adobe depanning; Reduce resistance, inwall at trapezoidal hardwood plate (9) is carved with a total tank (7), article 2～4, bypass channel (8), (7) and (8) communicate with an inlet opening (6) above the formwork, for making lubricated water distribution even, be equipped with in the inboard of trapezoidal hardwood plate (9) and go out the adobe positive direction and become cataphracted wter control piece (11), and branch network of rivers sheet (10) and 3～5 wter control pieces (11) circulation mutually that 2～4 zigzag fashions are housed between the inwall of wter control piece (11) and trapezoidal hardwood plate (9), and the piece number of control network of rivers sheet (10) is identical with the bar number of bypass channel (8).
More than four have symmetrical trapezoidal hardwood plate (9) Joint that meets the brickmaking functional requirement and constitute formwork.Core rod and formwork are fixed in rear end joint (1) respectively and go up the composition brick-making mould.
Adopt the advantage of manufacturing process of the present invention and the prepared tightweight hollow bricks made of pottery clay of mould thereof: have hole ratio height (55～65%), the light (600～700kg/m of volume unit weight
3), compression strength height (vertical core direction loading 100kg/cm
2More than; Cross-drilled hole direction loading 25～75kg/cm
2).Good frost resistance, (phenomenons such as the no bursting by freezing of 15 freeze thawing circulation, efflorescence, fragment, scaling hocket) shrinks for a short time, and cost is low, reduction construction unit gross investment about 15%.Be the wall body building material of the thin-walled high-strength light of a kind of infilled wall that is used for high level, superelevation story frame structure, partition wall, have significant social and economic benefit.
The tightweight hollow bricks made of pottery clay manufacturing process that the present invention introduces and the most preferred embodiment of mould thereof are as follows: with main aggregate potter's clay 35%, compound clay 23%, refer and synthesize material sawdust 10% and coal ash 25%, lightweight binding material land plaster 5%, designing requirement by weight percentage stirs through machinery is mixed, continues it, add an amount of blending stock water, mixed once more stirring becomes thick condiments; With thick condiments deliver to machinery to roller to rolling, it is become is in harmonious proportion the denseness closely knit uniform spy's material that bonds; Again spy's material is delivered to vacuum machine brick-making mould extrusion modling depanning, and be cut into one one tightweight hollow bricks made of pottery clay base by the product design specification (PDS) requirement through automatic gas cutting machine, again through the natural curing drying, be placed on and carry out 750～900 ℃ of roastings in the brickkiln, cooling, kiln discharge can become potter's clay thin-walled high-strength light hollow brick.
