Problems solved by technology

Existing sensors are pasted on the building to be tested, which brings a lot of inconvenience to the construction and deployment of sensors, low survival rate, poor durability, and low test accuracy
High-sensitivity sensors are easily affected by noise and changes in environmental conditions, resulting in the monitoring system not being able to correctly respond to changes in the parameters of the structure itself; The damage point is far away from the sensor and the damage of the structure cannot be predicted

Embodiment Construction

[0021] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0022] figure 1 It is the quasi-distributed test network diagram of the present invention. figure 2 It is the structural monitoring system diagram of the present invention.

[0023] A self-monitoring intelligent fabric reinforced concrete, which includes fabric mesh and electrodes; electrodes are pasted on the carbon fibers in the fabric mesh during the TRC production process; through dynamic detection of changes in the resistivity of the intelligent TRC, the stress and strain of each region in the structure Condition and distribution monitoring.

[0024] Further, the fabric net is formed by mixed weaving of carbon fiber bundles and non-alkali glass fiber bundles, the two kinds of fibers are laid vertically and horizontally to each other, and the joints are stitched with yarns.

[0025] Further, the fabric net can be laid with 3-5 layers of fabri...

Abstract

The invention discloses self-monitoring intelligent textile reinforced concrete and a manufacturing method thereof. In a process of TRC (textile reinforced concrete) manufacturing, an electrode is adhered to a carbon fiber in a textile net; stress, stress conditions and stress distribution of all regions in the structure are monitored by dynamically detecting the change of the resistivity of intelligent TRC. The self-monitoring intelligent textile reinforced concrete can supply effective bearing force and stretchability to the structure and supply an effective monitoring technology to the safety of the structure in a service stage; the aim of integrating a high-efficiency structure and real-time structure health monitoring is fulfilled.

Description

Technical field: [0001] The invention relates to a self-monitoring intelligent fabric reinforced concrete and a manufacturing method thereof. Background technique: [0002] With the rapid development of social economy and science and technology, a large number of existing and newly-built buildings, bridges, tunnels, and dams are subject to natural environment erosion, external loads, or human factors during operation. Various defects and damage, when the damage accumulates to a certain extent, will lead to structural failure. Therefore, how to monitor and diagnose these buildings and improve the construction safety and use safety of buildings is an urgent problem to be solved. [0003] In the structural health monitoring system, the long-term static stress (strain) monitoring and the detection of the dynamic response of the structure after excitation are important methods for evaluating the long-term performance of the structure and identifying damage. At present, the heal...
