Further, each end on described fixed mount is provided with a holdfast, and holdfast is perpendicular to fixed mount and arranges.
Further, the fixing bar of described breach both sides being provided with device for limiting, device for limiting includes being arranged on fixed mount one end to be fixed the circle silk on bar and is arranged on the snib with fixing hole on the fixing bar of the fixed mount other end.
This utility model compared with prior art has techniques below feature:
Adopt the position that this device can be buried underground needed for effectively road surface embedded strain gauge being fixed on; prevent because of the road surface structare layer that bankets, overlays, artificially touch by mistake or arrange the strain gauge position that the various factors such as sensor connecting line cause and move; effectively reduce strain gauge position and offset the experimental result error caused; the damage caused with the sharp objects friction in stone and soil when preventing sensor and wire movement; improve the survival rate of strain gauge, embedment strain gauge is had good protective effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of bracing frame and holder segment in this utility model;
Fig. 2 is application schematic diagram of the present utility model;
Number in the figure represents: 1 fixed mount, 1-1 fixes bar, 2 circle silks, 3 bracing frames, 4 snibs, 5 holdfasts, 6 embedded strain gauges, 7 cannelures.
Detailed description of the invention
Defer to technique scheme, as depicted in figs. 1 and 2, the utility model discloses the hold-down support of a kind of road surface embedded strain gauge 6, including the bracing frame 3 coordinated with embedded strain gauge 6, cannelure 7 is all circumferentially offered on the front end outer wall of described embedded strain gauge 6 and on the outer wall of rear end, described bracing frame 3 is arranged a pair, and bracing frame 3 is respectively supported on the cannelure 7 of embedded strain gauge 6 front end, rear end outer wall.
After road surface embedded strain gauge 6 is arranged in road surface, be squeezed power, shearing force etc., it is easy to strain gauge position is impacted. Strain gauge entirety is blocked by a kind of effective means that it is fixing exactly, is then fixed in road surface, to prevent its position from changing. For this this programme is provided with bracing frame 3 structure, it is directed on the outer wall of embedded strain gauge 6 and there is this construction features of cannelure 7, bracing frame 3 is supported in two grooves on embedded strain gauge 6, owing to groove can play locking effect, therefore bracing frame 3 and cannelure 7 coordinate, and can strain gauge be fixed. After being fixed by bracing frame 3 again, namely complete fixing strain gauge.
Specifically, bracing frame 3 is arranged on fixed mount 1, and fixed mount 1 bottom is fixed on inside road surface, makes fixed mount 1 that bracing frame 3, strain gauge entirety effectively to be fixed.
As the preferred technical scheme of one, bracing frame 3 includes the support bar of circular arc, and the supporting bar structure of circular arc can make bracing frame 3 extend into better in the cannelure 7 of strain gauge, plays better locking effect.
As for the structure of fixed mount 1, as it is shown in figure 1, fixed mount 1 is a triangle frame, being made up of three fixing bar 1-1, the middle part of a fixing bar 1-1 offers breach wherein, and described bracing frame 3 is fixed on breach.Triangle frame has stable structural strength, and after strain gauge is placed on bracing frame 3, certain protective effect also can be played in the front end of strain gauge, rear end by triangle frame.
The fixed form of fixed mount 1 is, each end on fixed mount 1 is provided with a holdfast 5, and holdfast 5 is perpendicular to fixed mount 1 and arranges; When installing strain gauge, first position can be determined, then holdfast 5 be pounded in road surface, after making fixed mount 1 firm, then carry out the fixing of strain gauge.
After strain gauge is fixed on bracing frame 3, for it being fixed further and limiting, being provided with device for limiting on the fixing bar 1-1 of breach both sides, device for limiting includes being arranged on fixed mount 1 one end to be fixed the circle silk 2 on bar 1-1 and is arranged on the snib 4 with fixing hole on the fixing bar 1-1 of fixed mount 1 other end. After strain gauge is placed on bracing frame 3, circle silk 2 is walked around strain gauge, be then inserted in the fixing hole of snib 4, just that strain gauge is fixing with bracing frame 3 for one firmly.
