Support contact, and the other end of axle power meter is contacted with support wall, support wall is provided with one block of steel plate, it is ensured that axle power meter and wall
Body contact is smooth.In actual installation process, because axle power meter volume is big, install very difficult.And due to operating mode
Etc. factor, axle power meter is contacted with support metope can not possibly be very smooth, causes axle power meter to there is unbalance loading phenomenon in use,
Because the string wire of axle power meter is located at the center of axle power meter, and now axle power meter is in force unbalance state, the steel of test
There is deviation in axial force of the supports, influence the monitoring of bracing members axle power, when unbalance loading is serious, may result in axle power meter unbalance stress
It is even, directly axle power meter is damaged, and mounted axle power meter cannot remove replacement, subsequently directly resulting in bracing members axle power cannot supervise
Survey, influence engineering safety.
The content of the invention
For above-mentioned problem, the utility model patent purpose there are provided a kind of reinforcing bar for measuring foundation ditch axial force of the supports
Meter, the unbalance loading based on solving the problems, such as axle power in engineer applied causes bracing members axle power to measure inaccurate.
The utility model to achieve these goals, is adopted the following technical scheme that：
A kind of reinforcing rib meter for measuring foundation ditch axial force of the supports, it includes string wire, coil, and string wire fixes holder, cable, temperature
Degree sensor, reinforcing rib meter main body and reinforcing rib meter connector；
Above-mentioned string wire is fixed holder and is fixed together with string wire, and string wire fixes the two ends that holder fixes string wire respectively, two
Individual string wire is fixed holder and reinforcing rib meter body upper is fixed on by way of screw thread；
The center of string wire is fixed in reinforcing rib meter main body, coil is fixed on above string wire；
In reinforcing rib meter body interior, a temperature sensor is installed, the temperature for monitoring reinforcing rib meter, with cable by coil
Reinforcing rib meter body exterior is connected to temperature sensor.
Further, the two ends of reinforcing rib meter main body are hollow-core construction, and include screw thread, and reinforcing rib meter connector one end is same
There is screw thread, reinforcing rib meter main body is connected through a screw thread fixation, has a fixing groove in reinforcing rib meter main body, is used for reinforcing rib meter connector
Reinforcing rib meter connector is connected with reinforcing rib meter main body.
Further, in one end of reinforcing rib meter connector, it is provided with the guide groove for welding.
The utility model realization principle：A kind of reinforcing rib meter for measuring foundation ditch axial force of the supports, mainly there is string wire, coil, string wire
Fixed holder, cable, temperature sensor, reinforcing rib meter main body, reinforcing rib meter connector composition.String wire is fixed holder and is fixed with string wire,
And string wire is fixed on reinforcing rib meter main body.After fixed string wire, coil is fixed on above string wire, vibrating wire acquirer is gathered axle
During power meter frequency, coil can encourage string wire, and pick up induced signal.Meanwhile, temperature sensor is fixed on reinforcing rib meter main body
Interior, for measuring reinforcing rib meter temperature, when calculating bracing members stress, temperature is used to correct the error that string wire is varied with temperature.String wire
After temperature sensor installation, coil and temperature sensor are drawn by cable.
Reinforcing rib meter main body two ends are provided with reinforcing rib meter connector, reinforcing rib meter connector by welding guide groove, during installation, by reinforcing bar
Meter is fixed on bracing members surface, by way of welding, reinforcing rib meter is welded on into bracing members outer surface, and around bracing members
4 reinforcing rib meters of welding, 4 reinforcing rib meters monitor the change of bracing members axle power simultaneously.
The beneficial effects of the utility model：
The utility model solves the problems, such as axle power meter unbalance loading in the monitoring of bracing members axle power, and axle power meter unbalance loading problem causes to survey
Amount data are inaccurate, it is also possible to axle power meter can be caused to damage, deep pit monitor is threatened.By the way of reinforcing rib meter, install simple, see
Survey data convenient, good stability, it is adaptable to which bracing members axle power is monitored.
