Abstract

The invention relates to a manufacturing technology for concrete road bricks with wet surfaces and dry bottoms. The manufacturing technology comprises the steps of 1, pouring concrete with the water-cement ratio ranging from 2-3 to 4-6 into a rubber mold; 2, shaking the concrete and enabling the concrete to be uniformly distributed at the bottom of the rubber mold; 3, pouring concrete with the water-cement ratio ranging from 2-3 to 7-10 into the rubber mold in the step 2; 4, carrying out sealing and extrusion forming through a press machine; and 5, conveying green bricks with surface layers formed in the step 4 into a heating furnace, curing the green bricks in the environment with the temperature being 36 DEG C and the relative humidity being 90% for 30 hours, delivering the green bricks and finally obtaining the finishes road bricks. The manufacturing technology for the concrete road bricks solves the problem that road bricks manufactured through the wet process are low in compressive strength and fracture resistance.

Description

The concrete road pavement brick processing technology that a kind of wet end is dry

Technical field

The present invention relates to a kind of concrete road pavement brick, belong to building industry technical field.

Background technology

Pavior brick is with cement and gathering materials as main raw material(s), processed, vibrate, pressurize or other moulding processs are made, It is a kind of for laying urban road footpath, city square, driveway, trail, park, parking lot and ground stress relatively Big occasion, such as concrete road surface and the block of ground surface works, the plate etc. in the place such as port container terminal, airport hardstand. Its surface can be have surface layer (expecting) or without surface layer (expecting)；True qualities or colour.For general wet method road surface It is inadequate all to there is grade of compressive strength in brick, the problem that anti-folding degree is low, and it is high that general dry method pavior brick all exists porosity, attractive in appearance The problem of degree difference.

Summary of the invention

The present invention is to solve that wet method pavior brick grade of compressive strength is inadequate, anti-folding degree is low, and dry method pavior brick porosity is high, beautiful The problem of sight degree difference, and then provide a kind of the wet end dry concrete road pavement brick processing technology

The technical scheme is that the technical scheme used for achieving the above object is to comprise the following steps:

The first step, the concrete that the ratio of mud is 2～3:4～6 is poured into rubber mold；

Second step, it is made to be uniformly distributed in bottom rubber mold through vibrations；

3rd step, rubber mold in step 2 pour into the concrete that the ratio of mud is 2～3:7～10；

4th step, through forcing press sealed extruded molding.

5th step, the adobe that the 4th step forms surface layer are sent in heating furnace, at temperature 36 degrees Celsius, relative humidity 90% In the environment of carry out steam-cured 30 hours, kiln discharge obtains finished product pavior brick afterwards

Further, the ratio of mud in step one is 2:4.3.

Further, the ratio of mud in step 3 is 3:10.

The invention have the benefit that the concrete road pavement brick that face of the present invention wet bottom technique makes, by wet method pavior brick with The Technology Integration of dry method pavior brick, makes surface layer with wet processing, it is ensured that reduces the porosity on surface and improves aesthetics Effect；Make bottom with dry process, solve wet method pavior brick grade of compressive strength inadequate, the problems such as anti-folding degree is low.No Being only that product is more diversified, the suitable application area also making product is more extensive.

Detailed description of the invention

Embodiment 1: the dry concrete road pavement brick processing technology in a kind of wet end comprises the following steps:

One, the concrete that the ratio of mud is 2:4.3 is poured into rubber mold；

Two, it is made to be uniformly distributed in bottom rubber mold through vibrations；

Three, the rubber mold in step 2 pours into the concrete that the ratio of mud is 3:10；

Four, through forcing press sealed extruded molding.

Five, the adobe forming surface layer is sent in heating furnace, enters in the environment of temperature 36 degrees Celsius, relative humidity 90% Steam-cured 30 hours of row, kiln discharge obtains finished product pavior brick afterwards.

Formed product: by be used for the framed decline of the rubber mold of molding, pressure head rise, open bed material door, by bed material (2: The concrete of 4.6) car sends in mould and carries out cloth, and shake and framed make bed material smooth, then bed material car return, pressure head Pressure bed material, after compression, pressure head is regained, and then opens fabric door, is sent into by the concrete that the ratio of mud is 3:10, and is arranged in the end The upper strata of material, the uniform cloth of fabric, on bed material, is then pressed under fabric car return, pressure head and exciting vibration moulding is become brick.Exciting Power is 70--260KN, and frequency of vibration is 8～55Hz, and time of vibration is 4-5s.

The demoulding: brick is placed on lifting platform rear returning in situ by the framed lifting platform position that moves forward to brick.

Obtaining product 600mm × 600mm × 60mm pitted skin concrete road pavement brick, precoat thickness is 9mm, joint thickness It it is 450 microns.

The concrete road pavement brick that technique makes is done at a kind of the wet end of the present embodiment, according to its technical characterstic, in conjunction with dry method road Face brick, intensity is high, and anti-folding degree is high, the advantages such as wet method pavior brick aesthetics high porosity is low, a kind of bed material dry method of making Make the concrete road pavement brick that fabric makes by wet method, combine all advantages of wet-dry change pavior brick；By to wet-dry change road surface The combination of brick advantage, solves most of shortcomings of conventional dry wet method pavior brick, not only makes pavior brick good looking appearance, colleague's tool Standby intensity folding high, anti-degree advantages of higher.Improve the practicality of concrete road pavement brick, reliability, safety.Also make simultaneously Construction engineering quality, attractive in appearance be improved.

Claims

1. the concrete road pavement brick processing technology that the wet end, a face is dry, it is characterised in that comprise the following steps:
