Abstract
Fan basis prestressed anchorage bolt exposes length measurement device. At present, a device capable of accurately and quickly determining the leakage length of the anchor bolt is lacked, so that the construction quality and progress are difficult, and errors are easily caused. The utility model comprises the following components: fixing nut (6), outer sleeve (2), inner tube (4) and two range finding sensors (3), two range finding sensors fix respectively the roof lower surface front and back both sides of outer sleeve, the outer sleeve with inner tube rotatable coupling, inner tube bottom with fixing nut pass through connecting plate (5) that circumference distributes and be connected fixedly. The device is used for measuring the exposure length of the pre-stressed anchor bolt of the fan foundation.
Description
Technical Field
The utility model relates to a device for measuring the exposure length of a prestressed anchor bolt of a fan foundation.
Background
Widely used prestressed anchorage bolt in the land fan basis installs strict requirement to the crab-bolt in the construction, and the crab-bolt is generally about 1mm to the length allowed error that leaks of anchor slab, and the workman level is uneven, simultaneously, lacks a device that can accurate and confirm the crab-bolt length that leaks fast, causes the difficulty for construction quality and progress, and causes the error easily.
Disclosure of Invention
The utility model aims to solve the existing problems and provides a device for measuring the exposed length of the prestressed anchor bolt of the fan foundation, which can measure the exposed length of the anchor bolt in real time and improve the measurement accuracy.
The above purpose is realized by the following technical scheme:
the utility model provides a fan basis prestressed anchorage bolt exposes length measurement device which constitutes and includes: the device comprises a fixed nut, an outer sleeve, an inner tube and two ranging sensors, wherein the two ranging sensors are respectively fixed on the front side and the rear side of the lower surface of a top plate of the outer sleeve, the outer sleeve is rotatably connected with the inner tube, and the bottom of the inner tube is fixedly connected with the fixed nut through a connecting plate which is circumferentially distributed.
The device for measuring the exposed length of the fan foundation prestressed anchor bolt is characterized in that the distance measuring sensor is an ultrasonic distance measuring sensor.
Has the advantages that:
1. the utility model is connected on the anchor bolt through the fixed nut thread until the bottom of the inner tube is jointed with the top of the anchor bolt, and the distance between the anchor bolt and the inner tube is measured through the ultrasonic ranging sensor, so that the rapid measurement can be realized.
2. The device is fixed by connecting the fixing bolt on the anchor bolt through threads, so that the situation that the device is unstable in fixation can be prevented, the fixed levelness of the device is ensured, and the accuracy of a measuring result is ensured.
Description of the drawings:
FIG. 1 is a front view of the present invention;
FIG. 2 is a bottom view of the present invention;
FIG. 3 is a schematic structural view of the present invention;
FIG. 4 is a schematic structural view of the present invention in use;
in the figure: 1. a control box; 2. an outer sleeve; 3. a ranging sensor; 4. an inner tube; 5. a connecting plate; 6. fixing a nut; 7. an anchor plate; 8. an anchor bolt.
The specific implementation mode is as follows:
example 1:
the utility model provides a fan basis prestressed anchorage bolt exposes length measurement device which constitutes and includes: the device comprises a fixing nut 6, an outer sleeve 2, an inner tube 4 and two ranging sensors 3, wherein the two ranging sensors are respectively fixed on the front side and the rear side of the lower surface of a top plate of the outer sleeve, the outer sleeve is rotatably connected with the inner tube, and the bottom of the inner tube is fixedly connected with the fixing nut through a connecting plate 5 which is circumferentially distributed.
Example 2:
according to the device for measuring the exposed length of the pre-stressed anchor bolt of the fan foundation in the embodiment 1, the distance measuring sensor is an ultrasonic distance measuring sensor.
The working principle is as follows: when in use, as shown in figure 4, the fixing nut is connected on the anchor bolt in a threaded manner until the lower surface of the inner tube is contacted with the top of the anchor bolt, the control box 1 is fixed on the upper top surface of the outer sleeve, the outer sleeve is rotatably connected with the inner tube, so that the fixing bolt can keep the outer sleeve not to rotate when screwed to enable the outer sleeve to be convenient for observing the measured distance, a controller, a display and a power supply are fixed in the control box, the power supply provides electric energy support for the ultrasonic ranging sensor, the display and the controller, the controller is a 51-series single chip microcomputer, the controller is electrically connected with the ultrasonic ranging sensor and the display, the ultrasonic ranging sensor measures the distance to the anchor plate 7 in real time after the device is installed, the distance that exposes for crab-bolt 8 promptly, the singlechip still is connected with the display screen for show the distance value that measures, the length that the staff adjusted the crab-bolt and exposed, the distance that measures when observing reaches the length that needs to expose and stops.
Claims (2)
1. The utility model provides a fan basis prestressed anchorage bolt exposes length measurement device which characterized by: the composition comprises: the device comprises a fixed nut, an outer sleeve, an inner tube and two ranging sensors, wherein the two ranging sensors are respectively fixed on the front side and the rear side of the lower surface of a top plate of the outer sleeve, the outer sleeve is rotatably connected with the inner tube, and the bottom of the inner tube is fixedly connected with the fixed nut through a connecting plate which is circumferentially distributed.
