Abstract
The present invention relates to a process for making a pottery clay light weight hollow brick and a mould thereof. The brick is made by the steps that natural pottery clay, clay soil, industrial wastes and water are mixed according to the provided process formula and homogeneously agitated by a machine to be seasonings; the seasonings are extruded and shaped by a machine mould, demoulded, dried and calcined to make the pottery clay light weight hollow brick. The hollow brick has the advantages of high hole rate (55 to 65%), light dry unit weight (600 to 700 kg/m+[3]), high compression strength (the vertical hole direction is more than 100 kg/cm+[2], and the cross hole direction is more than 25 kg/cm+[2]), good frost resistance, small constringency, low cost, etc. The brick is building material of light weight walls of filler walls and partition walls with high floor frame structures and ultra-high floor frame structures.
Description
The present invention relates to a kind of mould of making light-weight hollow-brick.
Brick is a main construction material of building the house, has a large capacity and a wide range, and its weight accounts for 60% of building gross weight in architectural engineering.At present, China's 80% above building is generally used clay brick.Because the unit weight of solid clay brick is big, increased the gross weight of building, cause the building foundation, frame beam column increases raw material consumptions such as reinforcing bar, cement, sandstone, not only increased the construction unit gross investment, and brought technical difficulty for the design of foundation engineering, frame beam column, in order to overcome this shortcoming, structural clay tile has all been adopted in now a lot of places, and the mould of making hollow brick also just arises at the historic moment.(building materials industry office in Sichuan compiles at " baking load-bearing hollow brick " book, China Construction Industry Press's 1977.6 front pages) in, disclosed a kind of mould of making hollow brick, this mould is made up of machine mouth and core tool, the machine mouth is the formwork made from timber or other material, the core tool comprises core bar, core print and core frame, core tool and machine mouth, be fixed on the rear end of machine mouth, on the machine mouth, be provided with water inlet pipe, tank, scale and water comb, on middle core bar, overlapped a taper resistance tube, this taper resistance tube has increased the resistance to the central part blank, reduces the speed of travel of central part blank, like this, solve the central part blank and the periphery blank speed of travel inconsistent aspect, played good effect, but this resistance tube remains in some shortcomings, is exactly even inadequately to the resistance of blank mudflow, thereby what can influence the quality of product, and the core tool of this structure is fit to make the hollow brick that honeycomb hole is arranged, and is not suitable for making the hollow brick of high hole rate.
The object of the present invention is to provide a kind of hollow brick mould that can remedy above-mentioned hollow brick mould deficiency, this mould can produce hole ratio up to 55%, and the compression strength height, the uniform hollow brick of quality.This mould adopts and weld way solution center blank and the inconsistent problem of periphery blank walking speed that helps fast pilot beam on core bar, and adobe wall, rib depanning speed are equated.
In order to realize purpose of the present invention, mould of the present invention is by core rod, core rod and rear end joint are formed, core rod comprises the core rod post, die head evacuated panels and core rod built-in beam, the die head evacuated panels is located at the front end of core rod post, core rod post rear end is welded on the core rod built-in beam, outside core rod, be with four blocks of trapezoidal hardwood plates of symmetry affixed formwork that surrounds mutually, the inwall of hardwood plate be carved with bypass channel and with formwork on advance that the hole, hole communicates and total tank, branch network of rivers sheet and wter control piece are housed on the formwork inwall, the water that enters from the inlet opening can circulate between tank and water sheet, formwork and core rod are fixed in respectively on the joint of rear end, be welded with vertical in core rod post inboard, cross rib speed pilot beam, at a distance of 1-2cm, the die head evacuated panels is each other at a distance of 0.8-1.5cm between formwork inwall and the die head evacuated panels.
The advantage of mould of the present invention is can produce hole ratio up to 55-65%, little (the 600-700 kilogram/rice of unit weight
3), compression strength height (vertical core direction loading 100 kilograms per centimeter
3More than, cross-drilled hole direction loading 25-75 kilograms per centimeter
3), good frost resistance is shunk for a short time, and the hollow brick that cost is low can reduce construction unit gross investment about 15%, is a kind of high level that is used for, and the high-strength light wall body building material of the infilled wall of superelevation story frame structure, partition wall has significant social and social benefit.
Fig. 1 is the profilograph of mould of the present invention.
As shown in Figure 1, mould of the present invention is by core rod, formwork and rear end joint three parts are formed, the front end of core rod post (3) is welded on the core rod built-in beam (2), give the adobe wall of moulding fully for making, help depanning speed to equate, inboard at several core rod posts (3) is welded with vertical, the horizontal fast pilot beam (4) that helps, constitute core rod, formwork is at core rod four blocks of trapezoidal hardwood plates of symmetry (9) to be loaded onto in the periphery, 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, and die head evacuated panels (5) is each other at a distance of 0.8-1.5cm.
For making the adobe depanning lubricated, any surface finish reduces resistance, is carved with a total tank (7) at the inwall of trapezoidal hardwood plate (9).2-4 bar bypass channel (8), these tanks communicate with inlet opening (6) on 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) that 2-4 piece zigzag fashion is housed between the inwall of wter control piece (11) and trapezoidal hardwood plate (9) and 3-5 piece wter control piece (11), water circulates between these water sheets, and the piece number of control network of rivers sheet (10) is identical with the bar number of bypass channel (8).
Above-mentioned four have symmetrical trapezoidal hardwood plate (9) Joint that meets the brickmaking functional requirement and become formwork, and core rod and formwork are fixed in respectively on the rear end joint (1).
Adopt the process of mould brickmaking of the present invention as follows:
With main aggregate potter's clay (or loess), the compound clay, admixture sawdust and coal ash, lightweight bonding material land plaster, percentage by weight on request is after mechanical mixture is mixed thoroughly, add suitable quantity of water and stir into the crude green body material, then this crude green body material is delivered to mechanical twin rollers pair roller, make it become the uniformly thin blank of density, should deliver to the brick-making mould extrusion modling by thin blank again, be cut into one one light hollow adobe through automatic gas cutting machine, again through natural curing, dry, be placed on and carry out 750-900 ℃ of roasting in the kiln, cooling, kiln discharge, promptly make thin-walled high-strength light hollow brick.
