Quality fluctuation method monitoring construction method of concrete filled steel pipe components based on piezoelectric materials

Abstract

The invention discloses a construction method for monitoring the quality fluctuation of steel pipe concrete members based on piezoelectric materials. According to the working principle of PZT substrates, intelligent aggregates and PZT reactors are arranged in multiple sections and layers. The construction method of the present invention solves the problem that the current steel pipe concrete member quality detection method stays in the test stage and has poor practicability, and is beneficial to data collection and comparative analysis; it realizes simultaneous detection of multiple concrete member quality indicators in one construction, such as concrete filling density and The bonding quality of the pipe wall concrete interface; and the results are verified by the impedance method, which is easy to operate and has high detection accuracy; the materials can be recycled again, and the utilization rate is high; the detection can be carried out simultaneously with the project, and will not affect the construction of the upper main structure. It can reduce the investment of construction period cost, and can carry out real-time online monitoring; it is especially suitable for evaluating the concrete pouring quality and interface bonding quality of steel pipe concrete members.

Description

technical field [0001] The invention relates to a construction method for monitoring the quality of steel pipe concrete members, in particular to a construction method based on piezoelectric materials, capable of detecting the concrete filling density of steel pipe concrete members and the bonding quality of the steel pipe interface at the same time in one construction, and can be applied online. Background technique [0002] my country's super high-rise building construction is in a period of rapid development. Due to its excellent structural performance, CFST columns are widely used in super high-rise buildings, and the cross-section of CFST members is getting larger and larger. A certain number of original partitions and vertical stiffeners are often arranged on the inner wall of the steel pipe of this type of large-section concrete-filled steel pipe column. The concrete below the junction of the original partition and the steel pipe cannot be vibrated directly and effect...

Problems solved by technology

[0007] The purpose of the present invention is to provide a monitoring construction method based on the quality fluctuation method of steel pipe concrete members based on piezoelectric materials, which solves the problem that the current steel pipe concrete member detection stays in the test stage and has poor practicability in practical applications, and at the same time solves the existing monitoring method only for Single indicator, if other indicators are detected, the construction needs to be rearranged, the material recovery rate is low, and the utilization rate is low; it also solves the problem that the existing technology only uses one method for monitoring, the problem of low accuracy and the problem that it cannot be applied to online monitoring
