Description
Technical field
The utility model relates to concrete protection field tests, particularly relates to a kind of concrete shield bonding strength tester.
Background technology
Current concrete in use, inevitably aging, defect phenomenon in various degree.As, concrete there will be obvious carbonization, so that causes the protective seam of reinforcing bar thin and occur that rebar corrosion stitches.And present stage is normally coated with protective materials at concrete surface for concrete protection, as SBR mortar or with the protective coating such as epoxy coating, chlorosulfonated polythylene coatings.After protective coating construction, in order to judge the cohesive strength size between scarce protective coating and concrete surface, special bonding strength tester will be used it will be detected.
Bonding strength tester of the prior art can only judge failing load magnitude range substantially, and accurately can not measure failing load size, and between while causing metrical error pair, the maintenance in ancestral room is unfavorable.
Summary of the invention
The purpose of this utility model is, provides a kind of concrete shield bonding strength tester.It can accurately measure failing load size.
The technical solution of the utility model: a kind of concrete shield bonding strength tester, the sleeve comprising pallet and be connected with described pallet, described sleeve inner is provided with hydraulic cylinder, the piston rod of hydraulic cylinder is connected with sucker, described piston rod comprises the first connecting portion and the second connecting portion, be provided with a Hookean spring between described first connecting portion, the second connecting portion, described sleeve is provided with the groove for showing described Hookean spring elongation.
Aforesaid concrete shield bonding strength tester, one end of described Hookean spring is provided with pointer, described Hookean spring be in former long time, pointer aligns with zero groove of groove.
Aforesaid concrete shield bonding strength tester, described piston rod is fixed on described sucker by nut lock.
Aforesaid concrete shield bonding strength tester, described piston rod part is provided with bulb, is connected with described sucker by described bulb.
Compared with prior art, concrete shield bonding strength tester of the present utility model is by arranging Hookean spring on the piston rod, and on sleeve, be provided with the groove indicating linear spring deflection, when carrying out the detection of concrete shield cohesive strength, deflection size by Hookean spring directly draws failing load value, reduce workload, cost-saving.

Being labeled as in accompanying drawing: 1-pallet, 2-sucker, 3-sleeve, 4-hydraulic cylinder, 5-piston rod, 51-first connecting portion, 52-second connecting portion, 53-Hookean spring, 7-pointer, 6-groove, 8-nut, 5a-bulb.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in detail.At this, illustrative examples of the present utility model and explanation for explaining the utility model, but can not be thought restriction of the present utility model.
Embodiment one.As shown in Fig. 1, concrete shield bonding strength tester provided by the invention, comprise pallet 1, pallet 1 is connected with sleeve 3, sleeve 3 inside is provided with hydraulic cylinder 4, piston rod 5 top of hydraulic cylinder 4 is connected with sucker 2, and sucker 2 and piston rod 5 are locked by nut 8, the cylindrical of sucker 2 and pallet 1 inwall clearance fit.Wherein, piston rod 5 comprises between the first connecting portion 51 and the second connecting portion 52, first connecting portion 51, second connecting portion 52 and is provided with a Hookean spring 53, and the length of Hookean spring 53 can be changed by the flexible of piston rod 5.Sleeve 3 is provided with the groove 6 for showing Hookean spring 53 elongation.In the present embodiment, one end of Hookean spring 53 is provided with pointer 7, described Hookean spring 53 be in former long time, pointer 7 aligns with zero groove of groove 6.
In order to strengthen the bonding strength between sucker 2 and concrete shield, when preventing from detecting, sucker 2 splits away off from concrete shield, need contact on outside surface simultaneously coat structure glue on sucker 2 with concrete shield.
Embodiment two, as shown in Fig. 2, concrete carbonization protective layer bonding strength tester provided by the invention, comprise pallet 1, pallet 1 is connected with stop sleeve 3, stop sleeve 3 is provided with hydraulic cylinder 4, piston rod 5 top of hydraulic cylinder 4 is provided with bulb 5a, and to be articulated and connected a sucker 2 by bulb 5a, sucker 2 and piston rod 5 are locked by nut 8, sucker 2 cylindrical and pallet 1 inwall clearance fit.Wherein, piston rod 5 comprises between the first connecting portion 51 and the second connecting portion 52, first connecting portion 51, second connecting portion 52 and is provided with a Hookean spring 53, and the length of Hookean spring 53 can be changed by the flexible of piston rod 5.Sleeve 3 is provided with the groove 6 for showing Hookean spring 53 elongation, and in the present embodiment, one end of Hookean spring 53 is provided with pointer 7, described Hookean spring 53 be in former long time, pointer 7 aligns with zero groove of groove 6.Being provided with pointer 7 in one end of Hookean spring 53 is optimum structure schemes, is obviously not limited thereto, as long as the organization plan of energy indicating graduation size all drops in the protection domain of this patent.
In the present embodiment, also for ease of the bonding strength strengthened between sucker 2 and concrete shield, when preventing from detecting, sucker 2 splits away off from concrete shield, need contact on outside surface simultaneously coat structure glue on sucker 2 with concrete shield.
The use procedure of above-mentioned concrete shield bonding strength tester is such: the protective coating region first selecting surface comparatively smooth is as test section, with alcohol, after acetone cleans this area protection coating surface, pallet is fixed, structure glue is coated at pallet inside surface, by structure glue, drawing head is adhered in pallet, after structure glue sclerosis, by the piston rod of hydraulic cylinder, drawing head is pulled from protective coating surface, by the deflection of Hookean spring, the size of failing load is calculated by formula F=KX, the cohesive strength between carbonization protective layer and concrete can be drawn.
Concrete shield bonding strength tester of the present utility model is by arranging Hookean spring on the piston rod, and on sleeve, be provided with the groove indicating linear spring deflection, when carrying out the detection of concrete shield cohesive strength, deflection size by Hookean spring directly draws failing load value, reduce workload, cost-saving.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
