Description
Technical Field
The utility model relates to a reinforced structure before concrete building life expires belongs to the building engineering field.
Background
According to the determination of an international concrete mechanism, the grade of the designed service life of the concrete is divided into three grades, wherein the first grade service life is 100 years, the second grade service life is 60 years, and the third grade service life is 30 years. The area of a newly built house in China exceeds 20 hundred million meters every year2More than 50% of the world, a great deal of projects such as concrete dams and bridges exist, and how to prolong the service life of concrete is a great subject to human beings, and if the concrete structure with the service life is completely dismantled, the work is disastrous. Firstly, the waste of resources is caused, secondly, the waste of manpower and material resources is caused, a large amount of construction waste harms the living environment of human beings, and a large amount of dust is generated in the dismantling process, so that the environment is greatly polluted.
Disclosure of Invention
The utility model aims at solving the problem that exists among the prior art, provide one kind under the condition that does not change original building function, can improve concrete member life's building before maturity concrete foundation reinforced structure greatly.
In order to achieve the above purpose, the utility model adopts the following technical scheme: a concrete foundation reinforcing structure before a building expires comprises a concrete pile, a concrete column, a concrete bearing platform and a concrete beam, wherein the concrete beam is fixed on the side surface of the concrete bearing platform; and implanting corrosion-resistant steel piles on the steel plate positioning devices along the axial direction of the concrete piles.
Preferably, high-strength fine aggregate concrete is injected around the corrosion-resistant steel pile at high pressure.
Preferably, the fixed steel plate positioning device is an arc-shaped steel pile positioning ring.
Preferably, the corrosion-resistant steel piles are arranged on two sides of the concrete beam respectively.
Preferably, a steel base plate is welded at the end of the concrete column and anchored on the concrete bearing platform through an expansion bolt, and the steel plate positioning device is arranged on the outer side of the steel base plate and is positioned on the same horizontal plane.
Preferably, the corrosion-resistant steel beam is arranged on the steel base plate and the steel plate positioning device.
Preferably, the corrosion-resistant steel pile is a sectional type steel pile and is fixedly connected through a steel pile interface at the end part of the steel pile.
The principle is as follows: the corrosion-resistant metal is adopted to reinforce the concrete member of the existing building, so that the service life of the concrete member can be greatly prolonged, a new performance composite structure is formed, and the concrete member and the corrosion-resistant metal member are organically combined under the condition of not changing the original building function.
Compared with the prior art, the utility model has the advantages of as follows:
1. the service life of the concrete building is prolonged.
2. The environment is protected.
