Abstract
A kind of detection of distress in concrete based on SMA and self-repairing system, more than one thread SMA is embedded into including tension side inside concrete body, SMA two ends and detection jack connection, the detection jack access heater of two SMA one end, the detection jack access resistance detection table of the two SMA other end, the change of SMA resistance is detected with resistance detection table, fracture width can be calculated；Heated by heater for SMA, SMA is returned to original state, and make crack autogenous healing, the utility model improves the durability and security of concrete body.
Description
Technical field
The utility model is related to detection and the recovery technique field of distress in concrete, and in particular to a kind of mixed based on SMA
The detection of solidifying soil cracking seam and self-repairing system.
Background technology
At present, with the increasingly quickening of China's economic construction high speed development and urbanization process, substantial amounts of concrete works
Come out, and the crack that concrete structure or component are produced directly affects the durability of whole engineering and the safety of structure, it is therefore, right
It is particularly important in concrete structure or structure member crevices Intelligent Measurement with reparation, still, existing Crack Detection complex operation,
Intelligent level is low, and detection error is big, easily produces false assessment to structure, and self-reparing capability is poor, and when artificially repairing
Technique and very complicated, above-mentioned technological deficiency, as those skilled in the art's technical problem anxious to be resolved.
The content of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of coagulation based on SMA
The detection of soil cracking seam and self-repairing system, are capable of the crack of accurate quick detection concrete structure, and can also selfreparing opened
The crack of exhibition.
In order to achieve the above object, the technical solution adopted by the present invention is：
A kind of detection of distress in concrete based on SMA and self-repairing system, including the inside tension side of concrete body 1 are pre-
More than one thread SMA 2 is embedded to, the two ends of SMA 2 and detection jack 3 are connected, and the detection jack 3 of two SMA 2 one end connects
Enter heater 5, the access resistance detection of detection jack 3 table 4 of two SMA 2 other end.
Compared with prior art, the beneficial effects of the utility model are：SMA 2 resistance is detected with resistance detection table 4
Change, can calculate fracture width；Heated by heater 5 for SMA 2, SMA 2 is returned to original state, and make to split
Stitch selfreparing.The utility model improves the durability and security of concrete body 1.SMA 2 material property is taken full advantage of,
Detection is accurate, and detection intelligence degree is high, is advantageously implemented Based Intelligent Control.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Utility model is further described below in conjunction with the accompanying drawings.
Inside reference picture 1, a kind of detection of distress in concrete based on SMA and self-repairing system, including concrete body 1
Tension side is embedded into more than one thread SMA 2, and the two ends of SMA 2 and detection jack 3 are connected, the inspection of two SMA 2 one end
The access heater 5 of jack 3 is surveyed, the access resistance detection of detection jack 3 table 4 of two SMA 2 other end passes through heater
5 heat for SMA 2, SMA 2 is returned to original state, and make crack autogenous healing.
Operation principle of the present utility model is:It is logical using resistance detection table 4 in the detection in the crack of concrete body 1
SMA 2 resistance variations can directly be detected by crossing detection jack 3, so as to calculate the width in crack, utilize itself leading to for SMA 2
The change of excess temperature returns to the characteristic of original state, is heated by heater 5 for SMA 2, SMA 2 is returned to original
Shape, and make crack autogenous healing, improve the durability and security of concrete body 1.
