Description
Technical Field
The invention relates to the technical field of intelligent ribs, in particular to a distributed fiber sensing BFRP intelligent rib production device.
Background
The BFRP rib is the basalt fiber reinforced plastic steel bar, has the advantages of high strength, fatigue resistance, good tolerance and the like, and is more and more widely and practically used in engineering in recent years. Because the elastic modulus of the BFRP rib is lower, the bonding and sliding effect of the BFRP rib is different from that of the common deformed steel bar, and the BFRP rib is arranged in the three-point bending beam, the cracking performance of the beam can be influenced. In order to research the crack initiation performance of a BFRP (bidirectional-bending-reinforced concrete) reinforced concrete structure and explore the influence of the bonding slippage of BFRP bars and concrete on crack development, a concrete three-point bent beam taking the BFRP bars as a combined material needs to be manufactured, and cracks need to be reserved. Due to the fact that the effect of monitoring the bonding slippage performance of the BFRP rib by using the point type sensor is poor, important data are easy to miss and the BFRP rib is easy to damage, and therefore the accuracy and the comprehensiveness of the data can be guaranteed by using the appropriate mode to arrange the information of the distributed optical fiber sensor for monitoring the bonding slippage, the strain and the like of the BFRP rib.
Common intelligent bars fall into the following categories: grooving on the surface of the rib material, namely grooving on the surface of the rib material in a polishing mode, placing the distributed optical fiber in the grooving, and packaging the distributed optical fiber by using colloid; punching the axis of the rib material, namely punching holes in the rib material by using laser, then penetrating the holes by using a distributed optical fiber, and packaging the holes by using a colloid; the surface winding performance of the rib material means that distributed optical fibers are arranged on the surface of the rib material in a winding mode and are bonded and fixed by adopting glue. The above methods are good and bad, the grooving process is the simplest, but the grooving has higher requirements on the rib material, and especially for the wire harness type rib material, the grooving on the surface of the rib material can influence the mechanical property of the rib material; the punching hole has the highest technical level requirement, the manufacturing cost is high, the collection of the strain information of the surface of the rib material is not accurate, and the requirement on the packaging material is high; the winding type has good strain collection on the surface of the rib material, can increase the monitoring precision of the sensor, but has a plurality of difficulties in spirally arranging the distributed optical fiber on the surface of the BFRP. The current situation of production of the current intelligent bar is summarized, and two problems mainly exist: firstly, the winding level of optical fibers of a product formed by manual winding and other modes is difficult to ensure, and the error caused by the uneven spacing to the test cannot be ignored; secondly, winding the optical fiber wastes time and labor, and has certain requirements on packaging materials.
