Epoxy resins and the mixing material of firming agent 3:1, it is generally the case that on a measuring point, foil gauge need to paste hoop and vertical two
Individual direction, in cross.Before pasting foil gauge, the epoxy resin mixed with firming agent that need to borehole wall surface be smeared is polished clean,
Upper cleaning solvent is dipped in rayon balls, as acetone, anhydrous alcohol, carbon tetrachloride equal solvent clean the spot at measured point, until
On cotton balls without obvious spot till, and note the most not with hands touch clean after surface.Then at the sticking veneer of foil gauge
Coat thin layer glue, such as KH501, KH502 glue, general suitable thin unsuitable thickness.
At present, the stickup of foil gauge, mainly by pasting manually, does not has operational convenient paste tool, thus imitates
Rate is low.Additionally, the sticking Quality of foil gauge depends on the proficiency level of testing crew, when artificial stickup foil gauge,
The pressing of finger is uneven, easily causes the uneven thickness of function of glue coating, and foil gauge is also very easy to tilt to produce angle simultaneously
Error, the shortcoming of this artificial pasting method is that performance accuracy is poor, glue is easily stained with in one's hands, and foil gauge damage probability is big, these
Bring bigger error will to the test result of strain.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of shaft wall structure model test piece strain gauge adhesion instrument,
This paste tool can be gone up simultaneously in two directions by strain gauge adhesion on the inside and outside concrete wall surface of the borehole wall, by holding with a firm grip
Handle and holding rod realize the Rapid pasting of foil gauge.
This utility model uses technology bill as follows:
The enforcement of this practicality utility model provides a kind of shaft wall structure model test piece strain gauge adhesion instrument, for straining
Sheet pastes on the region specified, and including handle 1, bolt riveting 2, holding rod 3, spring 4, shell 5, depression bar 6, cross pad 7, loads
Layer 8, rubber layer 9, cross locating slot 10, wire lead slot 11, foil gauge 12, foil gauge lead-in wire 13.
Realized the Rapid pasting of foil gauge by holding rod 3 of holding with a firm grip, holding rod is connected on handle by bolt riveting and spring, hands
Handle and shell are an entirety.
Outer casing bottom is the square of a hollow and middle part is the cylinder of hollow, and depression bar is the cylinder of plastics, adds
The material of carrier layer is rubber.
The connected mode of holding rod and depression bar is bonding, and there are a cross pad, depression bar and cross pad in the lower end of depression bar
The connected mode of sheet is bonding, has the loading layer, cross pad with the connected mode of loading layer to be below cross pad
Bonding, loading layer lower end has a rubber layer, loading layer to be bonding with the connected mode of rubber layer, is provided with one inside rubber layer
Cross locating slot and four wire lead slots.
Loading layer bonds together with outer casing inner wall, and shell and loading layer lower surface are designed with wire lead slot.
Cross pad below depression bar is equivalently-sized with cross locating slot, by elastomeric material have certain flexibility and
Elasticity, utilizes the extruding of loading layer and rubber layer so that acts on the power size ratio on foil gauge more uniform, can realize borehole wall mould
The stickup of the type test specimen certain flexibility of inside and outside wall foil gauge.
Size on each direction of cross locating slot is identical with foil gauge, and cross locating slot is possible not only to reality
Existing single direction strain gauge adhesion, and it is useful in the strain gauge adhesion on ring, vertical the two direction.
This utility model is provided with the wire lead slot of four foil gauges, it is possible to achieve the protective effect to foil gauge lead-in wire, and
And multiple directions arrange wire lead slot and make stickup foil gauge more convenient.
Strain gauge adhesion tool operation of the present utility model is simple, and holding rod of only need to manually holding with a firm grip just can be pasted onto answering sheet
Sticking area, improves strain gauge adhesion efficiency and accuracy.
