Abstract
The utility model discloses a kind of fiber deployment jig, the sensing optical fiber being applicable to large-sized concrete structure lays jig, can directly fix structurally, ensure that optical fiber is consistent with tested malformation, and pretension degree on sensing optical fiber can be regulated by nut, thus obtain optimum laying quality.This jig is made up of C type jig, screw rod, plastics fastener, rubber sheath, the first hexagonal nut, the first plain cushion, the second plain cushion, the second hexagonal nut and bullet pad; By C type jig, whole jig is fixed on tested structural edge, by rotating screw bolt by C type jig be fixed together by geodesic structure.Sensor fibre is tightly wrapped in wherein by plastics fastener and rubber sheath, the elasticity that two hexagonal nuts can regulate sensor fibre fixing.
Description
Technical field
The utility model 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.
Utility model content
In view of this, the utility model provides a kind of sensor fibre being applicable to large-sized concrete structure to 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, the utility model concrete grammar 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 utility model 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
Fig. 1 is the structural representation of the utility model fiber deployment jig.
Wherein, 1-C type jig, 2-screw rod, 3-plastics fastener, 4-rubber sheath, 5-first hexagonal nut, 6-first plain cushion, 7-second plain cushion, 8-second hexagonal nut, 9-bullet pad.
Embodiment
Below with reference to accompanying drawings embodiment of the present utility model is described.
The utility model provides a kind of sensing optical fiber and lays jig, and as shown in Figure 1, this jig is made up of C type jig 1, screw rod 2, plastics fastener 3, rubber sheath 4, first hexagonal nut 5, first plain cushion 6, second plain cushion 7, second hexagonal nut 8 and bullet pad 9.Plastics fastener 3 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 combine latter two semicylindrical opening is combined into cylindrical hole, cylindrical hole is mutually vertical with mounting hole but without overlapping.Screw rod 2 through a sidewall of the mounting hole of the mounting hole of the first hexagonal nut 5, first plain cushion 6, first fastener, the second fastener, the second plain cushion 7, second hexagonal nut 8, bullet pad 9 and C type jig 1, stretches into C type jig inner successively.Mounting hole in first fastener and the second fastener is unthreaded hole and after loading screw rod 2, has certain interval, so that plastics fastener 3 translation on screw rod between mounting hole hole wall and screw rod 2.Rubber sheath 4 loads the cylindrical hole of plastics fastener 3.Manhole in rubber sheath 4 is for placing optical fiber.
By C type jig 1, whole jig is fixed on tested structural edge, by rotating screw bolt 2 by C type jig 1 be fixed together by geodesic structure.Sensor fibre is tightly wrapped in wherein by plastics fastener 3 and rubber sheath 4, the elasticity that two hexagonal nuts can regulate sensor fibre fixing.Wherein C type jig, screw rod, plain cushion, hexagonal nut, bullet pad adopt SUS304 stainless steel.
In sum, these are only preferred embodiment of the present utility model, be not intended to limit protection domain of the present utility model.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
