Detailed description of the invention
As Figure 1-5, a kind of grinding coagulation clay model tool for test, detachably assemble by front and back's side plate 3, left side plate 4 and panel 5 including mold 1 and lower mold 2, described mold 1 and lower mold 2, and by surrounding multiple clamping body 6 clamping between mold 1 and lower mold 2；Through hole 7 and cavity 8 is had on side plate 3 before and after described mold 1 and lower mold 2, prop up stay tube 9 to be arranged in mold 1 and lower mold 2 by through hole 7 and cavity 8, described stay tube 9 forms headspace after concreting completes, and carries out the installation of humidity measurement mechanism 20.
As in Figure 2-4, described before and after between side plate 3 and left side plate 4 by arc convex 10 and groove 11 sliding connection, by wedge 12 and wedge-shaped slot 13 sliding connection between panel 5 and front and back side plate 3.Thus make upper and lower fixture the most detachable.
As shown in Figure 1, described clamping body 6 includes the fluting 14 being arranged on mold 1 and lower mold 2 edge, fluting 14 lower end of lower mold 2 is provided with paired lug 15, being provided with bearing pin 16 between lug 15 in pairs, rocking bar 17 one end is hinged by sleeve 18 and bearing pin 16, the other end is clamped on the fluting 14 of mold 1 by pin 19.During work, after upper lower clamp accurate positioning, pin 19 all around is rotated up and is stuck in fluting 14 upper surfaces successively, thus complete upper and lower fixture locking.
As it is shown in figure 5, described humidity measurement mechanism 20 includes that humidity sensor 21, humidity sensor 21 are arranged in the headspace that a stay tube 9 is formed, and sealed by the rubber stopper 22 at through hole 7.During work, when, after concrete initial set, extracting a stay tube 9 out, then be placed in by humidity sensor 21 in the headspace that a stay tube 9 is formed, through hole 7 is sealed by blend rubber plug 22.So can complete the monitoring to concrete humidity, and learn economization agent or other interpolation material impacts on humidity by analysis, thus take corresponding measure prevention that the substantive defects such as contraction, cracking occur because concrete is dried.
As it is shown in figure 5, be provided with seal washer 23 on described humidity sensor 21.Thus structure, had both played location supporting role, had ensured again its good seal.
As it is shown in figure 5, the surface that described rubber stopper 22 contacts with humidity sensor 21 connecting line is provided with epoxy sealing sheet 24.Thus structure, isolation inside concrete humidity is disturbed by external environment condition further.
As shown in Figure 6, described mold 1 lower surface is arranged with multiple locating dowel 25, and locating dowel 25 adapts with the hole, location on lower mold 2 upper surface.Thus structure, it is achieved mold is accurately positioned with lower mold.
The cavity inner wall that described mold 1 and lower mold 2 are constituted is provided with plastic sheeting.It is therefore prevented from concrete to overflow environment from each side plate installation position.
Operation principle and process:
1) side plate 3, left side plate 4 and panel 5 before and after in mold 1 and lower mold 2 are assembled according to mutual annexation, by a stay tube 9 through the through hole 7 on mold 1 and lower mold 2 after being completed, and carried out location by through hole 7, cavity 8 and support.
2) lower mold 2 is placed in ground grading, carries out lower-layer concrete and pour.
3) after lower-layer concrete coagulation forming reaches the stipulated time, dry the concrete at lower mold top, by locating dowel 25, mold 1 is accurately positioned with lower mold 2, finally by clamping body 6 clamping, carry out the floating of upper strata concreting and end face.
4) in above-mentioned casting process, also can carry out the detection of concrete humidity simultaneously.After concrete completes initial set, extracting a stay tube 9 out, then be placed in by humidity sensor 21 in the headspace that a stay tube 9 is formed, through hole 7 is sealed by blend rubber plug 22.Meanwhile, the wire of humidity sensor 21 is connected through rubber stopper 22 with controlling device, and records humidity delta data.
