Description
Technical field
The utility model relates to a kind of measurement mechanism, especially a kind of surface of contact cohesive strength measurement mechanism.
Background technology
Along with carrying out of a large amount of underground works of China, especially the building of tunnel engineering, quality is protected in the spray of its cavern's rock surface, and the cohesive strength problem of the surface of contact namely between crag and sprayed concrete seems very important.Whether its intensity reaches designing requirement, is directly connected to the quality safety of underground works and the reliability of engineering.So the measurement mechanism developing a kind of comprehensive concrete-rock contact face cohesive strength to construction quality and safety very important.
But, measure the measurement mechanism of sprayed concrete-rock contact face cohesive strength and measuring technique also exists larger defect and measures restriction at engineering circles at present.The first, the measurement mechanism or the equipment that are applicable to in-site measurement cohesive strength are at present little, and instrument has a few money measurement mechanism, and is can only measure under specified conditions.The second, the measurement mechanism or the equipment Application comparison that are applicable to in-site measurement cohesive strength are at present loaded down with trivial details, and measuring accuracy is lower.3rd, the measurement mechanism of current in-site measurement cohesive strength or equipment only can measure the sprayed concrete of floor, cavern and sidewall.The waist of cavern and top, hole cannot be measured, but these two positions sprayed concrete and the weakest link of rock contact face cohesive strength just.The size of its cohesive strength directly affects construction quality safety.
Utility model content
The utility model provides one and can be used for in-site measurement, more can be used for the surface of contact cohesive strength measurement mechanism of experiment measuring.
Realize the surface of contact cohesive strength measurement mechanism of the utility model object, comprise by swell fixture be fixed on below bonding object on steel model and regulate reaction frame, described steel model, built with preburied component, is provided with draw ring above described preburied component; Described adjustment reaction frame is fixed with lifting jack, is provided with unidirectional drag hook buckle above described lifting jack, described unidirectional drag hook buckle is provided with unidirectional drag hook, is hooked on draw ring below described unidirectional drag hook; Described lifting jack is connected with digital manual pump.
Described adjustment reaction frame comprises cruciform back up pad and four support bars, and the center of described back up pad is provided with center pit, and described unidirectional drag hook is through center pit; Four teats of described back up pad are respectively equipped with regulating tank, and described support bar is fixing on the supporting plate through regulating tank by setting nut.
Described preburied component comprises the horizontal clamp and vertical bar that center is fixed together, and the top of described vertical bar is provided with draw ring, and below is provided with horizontal loops, and the centre of described horizontal loops is provided with cross; Outside surface above described steel model is provided with clamp, and described horizontal card subcard is on the clamp of steel model.
The beneficial effect of surface of contact cohesive strength measurement mechanism of the present utility model is as follows:

Embodiment
As shown in figures 1-4, surface of contact cohesive strength measurement mechanism of the present utility model, comprise and be fixed on the steel model 9 on the bonding object 1 of below by swell fixture 2 and regulate reaction frame 3, described steel model 9, built with preburied component 7, is provided with draw ring 8 above described preburied component 7; Described adjustment reaction frame 3 is fixed with lifting jack 4, is provided with unidirectional drag hook buckle 6 above described lifting jack 4, described unidirectional drag hook buckle 6 is provided with unidirectional drag hook 5, is hooked on draw ring 8 below described unidirectional drag hook 5; Described lifting jack 4 is connected with digital manual pump 11.
Described adjustment reaction frame 3 comprises cruciform back up pad 12 and four support bars 10, and the center of described back up pad 12 is provided with center pit 14, and described unidirectional drag hook 5 is through center pit 14; Four teats of described back up pad 12 are respectively equipped with regulating tank 13, and described support bar 10 is fixed in back up pad 12 through regulating tank 13 by setting nut 15.
Described preburied component 7 comprises the horizontal clamp 71 and vertical bar 72 that center is fixed together, and the top of described vertical bar 72 is provided with draw ring 8, and below is provided with horizontal loops 73, and the centre of described horizontal loops 73 is provided with cross 74; Outside surface above described steel model 9 is provided with clamp 91, and described horizontal clamp 71 is stuck on the clamp 91 of steel model 9.
The course of work of surface of contact cohesive strength measurement mechanism of the present utility model is as follows:
With below dung body for rock, top bonding object is concrete is example:
First sprayed concrete and rock cohesive strength test point is chosen; Injection pre-treatment-dedusting is done to surface of contact, the separate type steel model of selected diameter D is fixed on rock surface by swell fixture; After installation, steel model inside surface coats release agent again, is convenient to follow-up form removal work, then is stuck on steel model by preburied component; Wrap up at the isolated material of the outside 5cm ~ 6cm of punching block, ensure that the concrete of itself and surrounding is isolated, form independent detection on-the-spot.Execution sprayed concrete work, when surface of test piece spray not at ordinary times, carry out polishing work.Treating that striking time reaches is first remove wrappage, then tears steel model open, swell fixture need not be extracted.Sprayed concrete test specimen proceeds maintenance.
When sprayed concrete test specimen reaches the curing period of design, prepare to measure.4 support bars are fixed on original setscrew, regulate adjustment reaction frame, start digital manual pump and just can directly measure.Can value.
Embodiment recited above is only be described preferred implementation of the present utility model; not scope of the present utility model is limited; do not departing under the utility model designs spiritual prerequisite; the various distortion that the common engineering technical personnel in this area make technical solutions of the utility model and improvement, all should fall in protection domain that claims of the present utility model determine.
