Abstract
A kind of steel arch-shelf resistance strain gauge fixing device, comprise pillar resistance strain gauge and be arranged on the erection support at pillar resistance strain gauge two ends respectively, erection support is made up of assembly department and fixing part, fixing part is provided with one for the installation preformed hole of the pillar resistance strain gauge that is installed, assembly department is the right-angle structure be made up of vertical portion and horizontal component, and assembly department is integrally formed structure by its vertical portion with fixing part, form one between the horizontal component of assembly department and fixing part for holding the draw-in groove of steel arch-shelf.Structure of the present invention is simple, reasonable in design, easy to operate, can be fixed on steel arch-shelf by solid and reliable for pillar resistance strain gauge, avoid the destruction that electric welding araeosystyle resistance strain gauge causes, and substantially increases the installation efficiency of pillar resistance strain gauge and is mounted to power.Meanwhile, device overall package is convenient, with low cost, practical.
Description
Technical field
The present invention relates to a kind of steel arch-shelf resistance strain gauge fixing device, be specially adapted to the fixing of underground engineering support Shaped Steel resistance strain gauge, a kind of steel arch-shelf resistance strain gauge fixing device specifically.
Background technique
When tunneling and underground engineering is constructed, usually need to carry out supporting to excavation country rock.At present, conventional supporting method has bolt-spary supports, steel arch-shelf adds Spraying of reinforcement mat with concrete supporting etc.After supporting completes, in order to ensure the safety in tunnel and underground engineering, need the distortion of monitoring steel arch-shelf under supporting state, now conventional method is fixed on steel arch-shelf by pillar resistance strain gauge to monitor, and its means of fixation is mainly welding.But the heat produced during welding is easy to the electric bridge in failure strain meter, cause its cisco unity malfunction.Therefore, design a kind of steel arch-shelf resistance strain gauge fixing device, avoid electric welding to be very necessary to the destruction that it causes.
Summary of the invention
Technical problem to be solved by this invention overcomes the shortcoming that in prior art, steel arch-shelf resistance strain gauge is easily destroyed in welding process, provides a kind of steel arch-shelf resistance strain gauge fixing device.This fixing device has structure feature simple, easy to use and with low cost simultaneously.
The present invention for the adopted technological scheme that solves the problem is: a kind of steel arch-shelf resistance strain gauge fixing device, comprise pillar resistance strain gauge and be arranged on the erection support at pillar resistance strain gauge two ends respectively, described erection support is made up of assembly department and fixing part, described fixing part is provided with one for the installation preformed hole of the pillar resistance strain gauge that is installed, described assembly department is the right-angle structure be made up of vertical portion and horizontal component, and assembly department is integrally formed structure by its vertical portion with fixing part, one is formed for holding the draw-in groove of steel arch-shelf between the horizontal component of described assembly department and fixing part.
The horizontal component of described assembly department is provided with the screwing bolts I for fixing steel arch-shelf 2.
The below of described installation preformed hole is also provided with the screwing bolts II for fastening pillar resistance strain gauge.
Beneficial effect of the present invention:
Steel arch-shelf resistance strain gauge fixture structure of the present invention is simple, reasonable in design, easy to operate, by two groups of screwing bolts that erection support and erection support top configure, solid and reliable for pillar resistance strain gauge is fixed on steel arch-shelf, avoid the destruction that electric welding araeosystyle resistance strain gauge causes, substantially increase the installation efficiency of pillar resistance strain gauge and be mounted to power.Installation preformed hole on erection support and the setting of installing screwing bolts below preformed hole, be convenient to adjust mounted pillar resistance strain gauge and fix, pillar resistance strain gauge can be made accurately to locate, ensure that installation quality.Meanwhile, device overall package is convenient, with low cost, practical.
Accompanying drawing explanation

Fig. 2 is the structural representation of erection support in the present invention;
Reference character: 1, pillar resistance strain gauge, 2, steel arch-shelf, 3, erection support, 301, assembly department, 302, fixing part, 4, preformed hole is installed, 5, screwing bolts I, 6, screwing bolts II.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described:
A kind of steel arch-shelf resistance strain gauge fixing device, comprise pillar resistance strain gauge 1 and be arranged on the erection support 3 at pillar resistance strain gauge 1 two ends respectively, described erection support 3 is made up of assembly department 301 and fixing part 302, described fixing part 302 is provided with one for the installation preformed hole 4 of the pillar resistance strain gauge 1 that is installed, described assembly department 301 is the right-angle structure be made up of vertical portion and horizontal component, and assembly department 301 is integrally formed structure by its vertical portion with fixing part 302, one is formed for holding the draw-in groove of steel arch-shelf 2 between the horizontal component of described assembly department 301 and fixing part 302.
The horizontal component of described assembly department 301 is provided with the screwing bolts I 5 for fixing steel arch-shelf 2.
The below of described installation preformed hole 4 is also provided with the screwing bolts II 6 for fastening pillar resistance strain gauge 1.
In the present invention, steel arch-shelf resistance strain gauge when mounted, first, respectively by the installation preformed hole snare of two erection supports at the two ends of pillar resistance strain gauge, and make two erection supports symmetrical, screwing bolts II be installed; Secondly, what consist of assembly department in erection support and fixing part is fixedly mounted on steel arch-shelf for the draw-in groove holding steel arch-shelf by erection support, then installs screwing bolts I; Finally, the relative position of adjustment erection support and steel arch-shelf, screws screwing bolts II and screwing bolts I, completes the installation of steel arch-shelf resistance strain gauge.This device has structure feature simple, easy to use and with low cost, can realize the monitoring of steel arch-shelf distortion safely, efficiently, reliably.
