Description

Geopolymer concrete reinforcing structure of concrete column

Technical Field

The utility model relates to the field of building reinforcement, in particular to a geopolymer concrete reinforcement structure of a concrete column.

Background

In the process of building construction or use, the underground water level may rise due to natural factors such as rainfall and the like, so that the basement bottom plate floats, the joint of the basement concrete column and the beam slab is subjected to punching damage, the joint of the column and the beam slab cracks and leaks water, and the like.

The geopolymer concrete is high-performance concrete mixed by adopting geopolymer instead of cement as a cementing material, the geopolymer is a novel green environment-friendly cementing material produced by taking industrial waste materials such as fly ash and slag as main raw materials, and the geopolymer concrete has the advantages of high early strength, strong anti-permeability and anti-corrosion capability, good durability, no environmental pollution and the like.

Disclosure of Invention

The utility model aims to provide a reinforcing structure which has a good reinforcing effect and can effectively prevent the joint of a column and a beam plate from cracking.

In order to achieve the above object, one technical solution of the present invention is:

the utility model provides a geopolymer concrete reinforced structure of concrete column, its characterized in that, including existing concrete column, existing concrete beam slab, geopolymer concrete reinforcement body, be provided with geopolymer concrete reinforcement body reinforcing bar net in the geopolymer concrete reinforcement body when existing concrete column is consolidated, chiseling shallow concrete and exposing concrete column structural reinforcement, existing concrete beam slab chiseling shallow concrete and exposing concrete beam slab structural reinforcement, geopolymer concrete reinforcement body reinforcing bar net and concrete column structural reinforcement, concrete beam slab structural reinforcement welded fastening.

In the further improvement, when the shallow concrete is excavated, the concrete reinforcing steel bar protection layer is chiseled and the reinforcing steel bar layer is chiseled.

In a further improvement, the geopolymer concrete reinforcing body is cast by using geopolymer concrete with one strength higher than that of the existing concrete column.

The geopolymer concrete reinforcement body is of a jacking structure similar to a bracket arch, the thickness of the geopolymer concrete reinforcement body is equal to the width of an existing concrete column, the length of a contact surface connected with the existing concrete column is 1-1.5 times of the width of the existing concrete column, and the length of a contact surface connected with an existing concrete beam plate is 2.5-3 times of the width of the existing concrete column.

In a further improvement, the geopolymer concrete reinforcing body reinforcing mesh is woven by adopting reinforcing steel bars with the same strength as the concrete column structural reinforcing steel bars, and the geopolymer concrete reinforcing body reinforcing mesh is in lap joint with the concrete column structural reinforcing steel bars.

The utility model has the technical effects that:

1. the reinforcing effect is good: through setting up geopolymer concrete reinforcement body in existing concrete column and existing concrete beam slab handing-over department, effectively avoided post and beam slab handing-over department to take place die-cut destruction and influence building structure safety to geopolymer reinforcement body adopts the top of similar to the bracket structure, and the stress is good.

2. The space occupies for a short time, does not influence the use of underground structure space: geopolymer concrete reinforcement mainly sets up in concrete column and beam slab handing-over department, compares in the traditional method of strengthening of enlarging the cross-section, and is less to underground space occupation, does not influence basement in-service use area.

3. Low-carbon energy-saving, green and environment-friendly: the reinforced structure is mainly implemented by geopolymer concrete, and the cementing material used by the geopolymer concrete is geopolymer mainly prepared by industries such as fly ash, blast furnace slag and the like, so that the production and manufacturing process reduces about 80% of carbon dioxide emission compared with cement, effectively protects ecological environment and promotes the low-carbon and energy-saving development of the building industry.

Detailed Description

For further understanding the contents, features and effects of the present invention, the following embodiments will be illustrated in detail with reference to the accompanying drawings.

Referring to fig. 1 to 2 together, a geopolymer concrete reinforcing structure of a concrete column according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1-2, the present invention provides a geopolymer concrete reinforced structure of a concrete column, including an existing concrete column 1, an existing concrete beam slab 2, and a geopolymer concrete reinforced body 3, wherein a geopolymer concrete reinforced body mesh 31 is disposed in the geopolymer concrete reinforced body 3, when the existing concrete column 1 is reinforced, shallow concrete is chiseled to expose a concrete column structural reinforcement 11, shallow concrete is chiseled from the existing concrete beam slab 2 to expose a concrete beam slab structural reinforcement 21, the geopolymer concrete reinforced body mesh 31 is welded and fixed with the concrete column structural reinforcement 11 and the concrete beam slab structural reinforcement 21.

Specifically, when the shallow concrete is excavated, the concrete reinforcement protection layer is chiseled off by the existing concrete column 1 and the existing concrete beam plate 2.
