The steel tube accommodating type recycled concrete column, disclosed by the utility model, realizes usage of waste concrete in low cost and environmental protection, fully utilizes resources and achieves favorable economic and social benefits.
Description
Technical field
The utility model relates in civil engineering the building technology that takes full advantage of discarded concrete, refers more particularly to through simple process regeneration concrete block and is poured in steel pipe column, forms steel pipe-containing type regeneration concrete post.
Background technology
Along with reconstructing of building, structure, discarded concrete rubbish discharge capacity is huge, processes this type of rubbish and will consume a large amount of man power and materials; On the other hand, forming concrete sand, stone and cement material is non-renewable resources, in many areas in the world, progressively seems in short supply.Therefore, the recycling of discarded concrete is the inevitable course.
At present, common Aggregate of recycled concrete complex treatment process, expense are very high, become the bottleneck problem of applying.Also there is the defect of steel pipe and regeneration concrete collaborative work in common steel tube regeneration concrete post at the bearing capacity aspect of performance.
Summary of the invention
The technical problems to be solved in the utility model is to provide that a kind of science and engineering skill is simple, the low steel pipe the promoted-containing type regeneration concrete post that is suitable for of cost.
In order to solve the problems of the technologies described above, the utility model provides a kind of steel pipe-containing type regeneration concrete post, comprise steel pipe and built to the layer of concrete formed in steel pipe by the cement concrete of newly mixing that is mixed with the discarded concrete block, described steel pipe inner wall is provided with some steel pegs, and described steel welding of peg is on steel pipe inner wall.
As further improvement of the utility model, described steel pipe is that cross sectional shape is circle, rectangle or other close-shaped tubular cylinder.
As further improvement of the utility model, the internal diameter of described round steel pipe or rectangle steel pipe range limit size reach 500mm when above, should pay the utmost attention at steel pipe inner wall weldable steel peg, and the spacing of steel peg should not be greater than 250mm.
As further improvement of the utility model, described steel pipe two ends are provided with the steel loop hoop.
The manufacture method of a kind of steel pipe-containing type regeneration concrete post comprises the following steps:
Step 1: be quincunx at steel pipe inner wall and be evenly arranged, the weldable steel peg;
Step 2: at steel pipe two ends outer wall weldable steel hoop;
Step 3: mix the discarded concrete block by match ratio to newly mixing in cement concrete, form containing type regeneration concrete;
Step 4: to steel pipe, build containing type regeneration concrete.
As further improvement of the utility model, the particle diameter of described discarded concrete block is 25mm-150mm.
As further improvement of the utility model, described discarded concrete block is 30%-50% at the weight incorporation of newly mixing cement concrete.
As further improvement of the utility model, described discarded concrete block, should be fully moistening before mixing green concrete.The described cement concrete of newly mixing is that cement, water reducing agent, micro-expanding agent and discarded concrete block mix and form, described discarded concrete block is before mixing green concrete, should be fully moistening, the 1%-2% of described water reducing agent mass of cement, the 5%-10% of described micro-expanding agent mass of cement.
As further improvement of the utility model, the strength grade of described discarded concrete block is at least C20.
Compared with prior art, the utlity model has following advantage.
1. described layer of concrete is by the discarded concrete block with newly mix cement concrete and mix to build to steel pipe and form.The ratio of mixing the discarded concrete block in the containing type regeneration concrete that the utility model adopts is high, and the treatment process of discarded concrete block is simple, and cost is low, can reach better economic benefit.
2. the described cement concrete of newly mixing is that cement, water reducing agent, micro-expanding agent and discarded concrete block mix and form.Mix water reducing agent and micro-expanding agent in the containing type regeneration concrete that the utility model adopts, contribute to improve its density in steel pipe, increase cooperative work performance between steel pipe and regeneration concrete.

The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in Figure 1, Figure 2 and Figure 3, a kind of steel pipe-containing type regeneration concrete post, comprise steel pipe 1 and layer of concrete, and layer of concrete is built to steel pipe 1 and formed by the cement concrete 4 of newly mixing that is mixed with discarded concrete block 2.
Implementation method of the present utility model comprises the following steps:
(1), be quincunx at steel pipe 1 inwall and be evenly arranged, weldable steel peg 3;
(2), at steel pipe 1 two ends outer wall weldable steel hoop 5;
(3), mix discarded concrete block 2 by match ratio to newly mixing in cement concrete 4, formation containing type regeneration concrete;
(4), to steel pipe 1, build containing type regeneration concrete.
The particle diameter of discarded concrete block 2 is 25mm-150mm.
Discarded concrete block 2 is 30%-50% at the weight incorporation of newly mixing cement concrete 4.
Newly mix cement concrete 4 and form for cement, water reducing agent, micro-expanding agent and discarded concrete block 2 mix, the 1%-2% of water reducing agent mass of cement, the 5%-10% of micro-expanding agent mass of cement.
The strength grade of discarded concrete block 2 is at least C20.
Teachings herein is example of the present utility model and explanation; but do not mean that the obtainable advantage of the utility model is so limited, may be to wherein one or more of the advantage that realizes in the simple transformation of structure and/or some embodiments all in the application's protection domain in every the utility model practice process.
