Abstract
The invention discloses a test detection method for strength resilience of a thin concrete member, which is a test detection method for the strength resilience of concrete. The technical scheme adopted is as follows: the thin concrete member (such as a concrete prefabricated sash) to be detected is placed on a flat concrete ground, cast-in-place concrete is filled in the prefabricated sash, and after the filled concrete reaches a certain strength (C20), the filled concrete and the prefabricated member form a stable integral structure and are firmly bonded with the ground. And at the moment, the top surface and the side surface of the prefabricated sash are rebounded by using a concrete strength resiliometer, and the concrete strength of the prefabricated sash can be calculated after the rebound data is obtained.
Description
The technical field
The invention relates to a test detection method for concrete strength resilience.
Background
At present, thin concrete members are easy to deform or slide when rebounded by a concrete rebound tester due to small rigidity or light weight, so that the strength of the solid body of the member cannot be rebounded. And because the section size of the component is not standard or the inside has the reinforcing bar, can not cut out the test piece that the test specification required and carry out the pressure test.
Disclosure of Invention
In order to solve the defect that the thin concrete member cannot be directly rebounded by using a rebound tester on site, the invention provides a method for reinforcing the concrete member on site and rebounding the strength by using the concrete rebound tester, which solves the problem of strength detection of the thin concrete member on site and is simple and easy to implement.
Detailed Description
The technical scheme adopted by the invention for solving the technical problems is as follows: the thin concrete member (such as a concrete prefabricated sash) to be detected is placed on a flat concrete ground, cast-in-place concrete is filled in the prefabricated sash, and after the filled concrete reaches a certain strength (C20), the filled concrete and the prefabricated member form a stable integral structure and are firmly bonded with the ground. And at the moment, the top surface and the side surface of the prefabricated sash are rebounded by using a concrete strength resiliometer, and the concrete strength of the prefabricated sash can be calculated after the rebound data is obtained.
The invention has the advantages that the solid strength of the thin concrete member can be detected on site, and the implementation is convenient.
Claims (1)
1. A strength rebound test detection method of a thin concrete member is characterized by comprising the following steps: placing the prefabricated concrete member on the concrete ground, filling cast-in-place concrete in the member, tamping and leveling the concrete to expose the top surface and the outer side surface of the member, and performing strength resilience on the top surface and the outer side surface of the prefabricated sash by using a concrete strength resilience meter after the strength of the filled concrete reaches C20 strength.
