Abstract
The utility model relates to anchor cables, and particularly relates to an anchor cable tension precise calibration device. The anchor cable tension precise calibration device comprises an anchor head, wherein the inner side of the anchor head is provided with a force gauge, the outer side of the anchor head is provided with a jack, the jack is provided with a pressure gauge above and connected to a reading meter I, and the force gauge is provided with a pressure gauge above and connected to a reading meter II. The anchor cable tension precise calibration device provided by the utility model is simple and convenient to operate, stable, safe and reliable.
Description
Technical field
The utility model relates to anchor cable, relates in particular to the accurate caliberating device of anchor cable tension force.
Background technology
The ultimate principle of anchor cable locking is off-load after being stretched to certain numerical value, move with anchor cable and tighten locking at off-load process stream line card, will some loss of prestress in this process, therefore in the tensioning fixation stretching process, need surpass stretch-draw, be used for remedying the loss of prestress that produces because of tensioning fixation technology.
Loss of prestress during tensioning fixation and tensioning equipment, anchoring material, operating personnel are relevant, detect data according to test, and anchor cable locking loss value can reach stretch-draw value 20% ~ 80%, and anchor cable locks the loss value and differs obvious as can be seen from data.Control and conventional way is generally super stretch-draw 10% ~ 20%, can't accurately determine the loss of prestress value.Excessive as lock value, under foundation pit deformation, anchor cable stressed will be very soon the value of overstepping the extreme limit and bring danger; As loss of prestress is excessive when locking, and foundation pit deformation is moderate finite deformation, more than either way very easily cause catastrophic effect.
Summary of the invention
The utility model is intended to address the aforementioned drawbacks, and provides a kind of anchor cable tension force accurate caliberating device.The utility model is determined the actual loading of anchor cable effectively, accurately demarcates prestressed loss value, guarantees the accurate of lock value, and error precision can reach 0.1kN.
For addressing the above problem, the accurate caliberating device of a kind of anchor cable tension force, it comprises an anchor head, the inboard of anchor head is provided with dynamometer, the outside of anchor head is provided with lifting jack, and the lifting jack top is provided with tensimeter and connects read table one, and the dynamometer top is provided with tensimeter and connects read table two.
The utility model is in the anchorage cable stretching process, calibrate the stretching force of hydraulic jack in the difference of the actual lock power of anchor cable, accurately calibrate stretch-draw loss value, guarantee that the final latching force precision of anchor cable meets the requirements, the tension calibration device is easy and simple to handle, steady, safe, reliable.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the utility model synoptic diagram.
Embodiment
As shown in Figure 1, the accurate caliberating device of a kind of anchor cable tension force, it comprises an anchor head 1, the inboard of anchor head 1 is provided with dynamometer 2, the outside of anchor head 1 is provided with lifting jack 3, and lifting jack 3 tops are provided with tensimeter and connect read table 1, and dynamometer 2 tops are provided with tensimeter and connect read table 25.
The accurate caliberating device of a kind of anchor cable tension force, when implementing, dynamometer 2 is installed on anchor head 1 inboard, locking back dynamometer 2 does not take out, when tensioning fixation, to lifting jack 3 locking and pressurizing progressively, and read the force value of dynamometer 2, shown by read table 25, read the force value of lifting jack 3 simultaneously, shown by read table 1, after testing force meter force value reaches the design lock value, stop to load, read table one 4 data presented deduct read table 25 data presented institute value and are the loss of prestress value, by after choosing the difference position and carrying out test process, can draw the loss of prestress value of this equipment.
