Abstract

The invention discloses a manufacturing method of a recycled low-strength concrete wall beam, which comprises the following steps: grinding and screening one of waste concrete, tiles and ceramic building rubbish to obtain manual coarse aggregate of 5-20mm and manual fine aggregate; and mixing water, cement, flyash, the manual fine aggregate and the manual coarse aggregate into recycled low-strength concrete, and pouring on common reinforced concrete beams to replace the traditional brick walls, wherein one cubic meter of the recycled low-strength concrete is prepared from 200Kg of water, 153Kg of cement, 83Kg of flyash, 516-648Kg of manual fine aggregate and 1048-1316Kg of manual coarse aggregate. The invention saves resources and protects the environment to the largest extent, and achieves the purpose of sustainable development.

Description

A kind of manufacture method of the low strong concrete wall beam of regenerating
Technical field
The present invention relates to civil engineering technology, particularly a kind of manufacture method of the low strong concrete wall beam of regenerating.
Background technology
Wall beam is a kind of combining structure of being made up of lay bricks body of wall and reinforced concrete beam, compares with plain bars concrete beam to have the advantage of saving steel.But there are two deficiencies in traditional wall-beam structure: the body of wall globality of 1, laying bricks is relatively poor.2, the contact surface of laying bricks between body of wall and the reinforced concrete beam is combining structure strength weak position, often shear failure takes place and makes wall beam lose holistic resistant behavior, utilizes the low strong concrete of regeneration to substitute the body of wall of laying bricks and can overcome above deficiency.In addition, firing loam brick and will take the farmland, has been restriction development enterprise of country.And building waste such as at present a large amount of discarded concretes that occur, brick and tile, pottery and flyash are influencing surrounding enviroment.Utilize above obsolete material, mix the alternative body of wall of laying bricks of the low strong concrete of regeneration that intensity 5Mpa-7.5Mpa is made in small amount of cement cast in situs, not only can turn waste into wealth, reduce construction investment, strengthened the holistic resistant behavior and the intensity of wall beam combining structure simultaneously again.
Summary of the invention
Purpose of the present invention just is to overcome the deficiency of traditional wall beam, uses the low strong concrete of cast-in-place regeneration instead and substitutes the tradition body of wall of laying bricks and make the low strong concrete wall-beam structure of regeneration.
The present invention is achieved in that and crushes and screens a kind of with in discarded concrete, brick and tile and the ceramic building rubbish and obtain artificial coarse aggregate of 5-20mm and artificial fines; The materials that the low strong concrete of regeneration is every cubic metre are: water 200Kg, cement 153Kg, flyash 83Kg, artificial fines 516-648Kg, artificial coarse aggregate 1048-1316Kg; The materials of the low strong concrete of above-mentioned regeneration are mixed and made into the low strong concrete of regeneration that intensity is 5Mpa-7.5Mpa, are cast on the plain bars concrete beam, the alternative tradition body of wall of laying bricks.
The present invention reaches to greatest extent and economizes on resources, protects environment, realizes the purpose of sustainable development.

Fig. 1 is a structure chart of the present invention.
The low strong concrete wall of mark among the figure: 1---regeneration; 2---plain bars concrete beam; 3---wall beam support column.
The specific embodiment
Embodiment 1:
As shown in Figure 1, on plain bars concrete beam 2, build body of wall 1 with the low strong concrete of regeneration; The low strong concrete of regeneration adopts discarded concrete to crush and screen and obtains artificial coarse aggregate of 5-20mm and artificial fines; The materials of every cubic metre of low strong concrete of regeneration are as shown in table 1, and the low strong concrete strength of regeneration is 7.5Mpa.
