Abstract
The invention discloses an optical fiber laying fixture. The sensing optical fiber laying fixture applicable to a large concrete structure can be directly fixed on the structure, deformation of optical fibers and the to-be-monitored structure is ensured to be consistent, and the pre-tensioning degree of the sensing optical fibers can be adjusted through nuts, so that the optimum laying quality is realized. The fixture consists of a C-shaped fixture body, a screw, a plastic clamping piece, a rubber sheath, a first hexagonal nut, a first flat gasket, a second flat gasket, a second hexagonal nut and an elastic gasket. The whole fixture is fixed on the edge of the to-be-monitored structure through the C-shaped fixture body, and the C-shaped fixture body and the to-be-monitored structure are fixed together through rotation of the screw. The plastic clamping piece and the rubber jacket wrap the sensing optical fibers tightly, and the fixation tightness of the sensing optical fibers can be adjusted by the aid of the two hexagonal nuts.
Description
Technical field
The present invention relates to fiber deployment jig.
Background technology
Utilize Distributed Optical Fiber Sensing Techniques to when being monitored by geodesic structure, must ensure sensor fibre and be kept by geodesic structure being out of shape consistent, the laying of sensor fibre is particularly crucial.In field of civil engineering, by geodesic structure to be usually that unit forms an entirety with regular length, required laying optical fiber reaches tens meters of even hundreds of rice.Disposal route conventional at present normally utilizes nylon cable tie or special bonding agent that sensor fibre is fixed on by geodesic structure, but due to the structural limitations of nylon cable tie own, when by geodesic structure bulk deformation, can not ensure that optical fiber and tested structure synchronization are out of shape completely, thus it is larger to cause optical fiber to survey data error.And in addition, because bonding agent is affected by environment comparatively large, be difficult to meet long term monitoring requirement.
Summary of the invention
In view of this, the invention provides a kind of sensor fibre being applicable to large-sized concrete structure and lay jig, directly can fix structurally, ensure that optical fiber is consistent with tested malformation, and the pretension degree of sensing optical fiber can be regulated by nut, thus obtain optimum laying quality.
For solving the problems of the technologies described above, concrete grammar of the present invention is as follows:
A kind of fiber deployment jig, this fiber deployment jig is made up of C type jig, screw rod, plastics fastener, rubber sheath, the first nut and the second nut; Plastics fastener is made up of the first fastener of symmetrical shape and the second fastener, in first fastener and the second fastener, all there is mounting hole and semicylindrical opening, and the first fastener and the second fastener combination rear semicircle post holes are combined into cylindrical hole, cylindrical hole is mutual vertical with mounting hole but without overlapping; Screw rod through a sidewall of the mounting hole of the first nut, the mounting hole of the first fastener, the second fastener, the second nut and C type jig, stretches into C type jig inner successively; Mounting hole in first fastener and the second fastener is unthreaded hole and after loading screw rod, has gap between mounting hole hole wall and screw rod; Rubber sheath loads the cylindrical hole of plastics fastener; Manhole in rubber sheath is for placing optical fiber.
Preferably, between described first nut and the first fastener, the first plain cushion is installed; Second plain cushion is installed between the second fastener and the second nut, between the second nut and C type jig, bullet pad is installed.
Preferably, described C type jig, screw rod, two plain cushions, two nuts and described bullet pads all adopt SUS304 stainless steel.
Beneficial effect:
The present invention is closely fixed on by geodesic structure by C type jig and screw rod, sensor fibre optical fiber is through rubber sheath, then by nut, sensor fibre is tightly wrapped in rubber sheath, ensure sensor fibre and kept by geodesic structure being out of shape consistent, and can the tightness that optical fiber is fixed to be regulated.
Accompanying drawing explanation
