Abstract
The invention discloses a steel pipe-contained recycled concrete column and an implementation method thereof. The steel pipe-contained recycled concrete column comprises a steel pipe (1) and a concrete layer, wherein the concrete layer is formed by pouring the newly agitated concrete (4) mixed with waste concrete block bodies (2) into the steel pipe (1). The method can use the waste concrete with lost cost, protects the environment, fully utilizes resources, and obtains good economic and social benefits.
Description
Technical field
The present invention relates to take full advantage of in the civil engineering building technology of discarded concrete, refer more particularly to through simple process regeneration concrete block and be poured in the steel pipe column steel pipe of formation-containing type regeneration concrete post and implementation method.
Background technology
Along with reconstructing of building, structure, discarded concrete rubbish discharge capacity is huge, handles this type of rubbish and will consume a large amount of man power and materials; On the other hand, constituting concrete sand, stone and cement material is non-renewable resources, progressively seems in short supply in many areas in the world.Therefore, the recycling to 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 defective 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 problem to be solved in the present invention provides that a kind of science and engineering skill is simple, low steel pipe-containing type regeneration concrete post and the implementation method that is suitable for promoting of cost.
In order to solve the problems of the technologies described above, the invention provides a kind of steel pipe-containing type regeneration concrete post, comprise steel pipe and layer of concrete, described layer of concrete is by the discarded concrete block and newly mix the cement concrete mixing and build to steel pipe and form.
As a further improvement on the present invention, described steel pipe inwall is provided with some steel pegs, and described steel nail solder is connected on the steel pipe inwall.
As a further improvement on the present invention, described steel pipe is that cross sectional shape is circle, rectangle or other close-shaped tubular cylinder.
As a further improvement on the present invention, the internal diameter of described round steel pipe or rectangle steel pipe range limit size reach 500mm when above, then should pay the utmost attention at steel pipe inwall weldable steel peg, and the spacing of steel peg should be greater than 250mm.
As a further improvement on the present invention, 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 may further comprise the steps:
Step 1: be quincunx even layout, weldable steel peg at the steel pipe inwall;
Step 2: at steel pipe two ends outer wall weldable steel hoop;
Step 3: mix the discarded concrete block by match ratio in the cement concrete to newly mixing, form containing type regeneration concrete;
Step 4: build containing type regeneration concrete to steel pipe.
As a further improvement on the present invention, the particle diameter of described discarded concrete block is 25mm-150mm.
As a further improvement on the present invention, described discarded concrete block is 30%-50% at the weight incorporation of newly mixing cement concrete.
As a further improvement on the present invention, 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 mixing form, described discarded concrete block is before mixing green concrete, should be fully moistening, the 1%-2% of described water reducing agent by mass of cement, the 5%-10% of described micro-expanding agent by mass of cement.
As a further improvement on the present invention, the strength grade of described discarded concrete block is at least C20.
Compared with prior art, the present invention has the following advantages.
1. described layer of concrete is by the discarded concrete block with newly mix the cement concrete mixing and build to steel pipe and form.Mix the ratio height of discarded concrete block in the containing type regeneration concrete of the present invention, 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 mixing form.Mix water reducing agent and micro-expanding agent in the containing type regeneration concrete of the present invention, help to improve its density in steel pipe, increase cooperative work performance between steel pipe and the regeneration concrete.
3. described steel pipe inwall is provided with some steel pegs, and described steel nail solder is connected on the steel pipe inwall.Described steel pipe two ends are provided with the steel loop hoop.Structure of the present invention arranges steel peg and steel loop hoop, strengthens the comprehensive stress performance of steel pipe-containing type regeneration concrete post.
