The utility model discloses can be very convenient while to concrete surface shallow crack width and degree of depth measure.
Description
Technical Field
The utility model belongs to the technical field of building structure component's test, concretely relates to device of shallow crack width of simultaneous monitoring concrete surface and degree of depth.
Background
The Chinese patent 201410250785.8 discloses an ultrasonic wave phase reversal test method for shallow crack depth on concrete surface, and the adopted devices are an emitting transducer and a receiving transducer. However, the method disclosed in the document can only measure the depth of the shallow cracks on the concrete surface by using the transmitting transducer and the receiving transducer, but cannot simultaneously measure the width of the shallow cracks on the concrete surface.
The chinese invention patent 201410301546.0 discloses a concrete surface crack width measuring instrument and method based on a smart phone, which is installed with a crack image processing program. The method comprises the steps of starting a crack image processing program of the smart phone, collecting a crack image through a camera of the smart phone, enabling the crack to be displayed on a screen of the smart phone, carrying out image analysis processing on the crack image, and calculating the width of the crack. However, this method can only measure the width of the crack on the concrete surface, but cannot simultaneously measure the depth.
Disclosure of Invention
The utility model aims to solve the technical problem that a convenient to use's device that can monitor shallow crack width of concrete surface and degree of depth simultaneously is provided.
The utility model discloses a realize like this:
an apparatus for simultaneously monitoring the width and depth of a concrete surface crack, comprising: a movable rod, a transmitting transducer, a receiving transducer and a width tester;
the travel bar, comprising: the lever part and the two end supports; the supports at the two ends are connected through the bar body part in the middle; the two end supports are fixedly arranged on the surface of the concrete with cracks;
the transmitting transducer, the receiving transducer and the width tester are arranged on the shaft part of the movable rod in a penetrating way; the width tester is located between the transmitting transducer and the receiving transducer.
Further, scales are arranged on the surface of the lever body part.
The utility model has the advantages that: the width and the depth of the shallow crack on the surface of the concrete can be conveniently measured.
Drawings
The invention will be further described with reference to the following examples with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
As shown in fig. 1, an apparatus for simultaneously monitoring the width and depth of a crack on a concrete surface comprises: a movable rod 1, a transmitting transducer 21, a receiving transducer 22, and a width tester 3.
The transmitting transducer 21, the receiving transducer 22 and the width tester 3 are all arranged on the bar body part 11 of the moving rod 1 in a penetrating way; the width tester 3 is located between the transmitting transducer 21 and the receiving transducer 22.
The surface of the lever portion 11 is provided with scales.
The left end support 12 of the travel bar 1 is directly connected to the concrete surface and can be perforated or fixed with high strength glue. The right-hand support 12 is required to have a support rod (not shown) that can move along the axis of the shaft portion 11, and a hole is drilled in the support rod, and the shaft portion 11 can slide in the hole. The reason why the support rod is designed to move along the bar portion 11 is that if both ends are fixed, the two supports are collapsed by the excessive width of the crack generated on the concrete surface, and the right end can be fixed to the concrete by the support rod.
The transmitting transducer 21 and the receiving transducer 22 are the transmitting transducer and the receiving transducer disclosed in the chinese patent 201410250785.8.
The width tester 3 has the same principle as the smartphone disclosed in chinese patent 201410301546.0, and has a camera, a screen, and a crack image processing program. The distance between the camera of the width tester 3 and the concrete surface is calculated by the height of the supports 12 at the left and right ends. The scales can be added on the left end support 12 and the right end support 12, or the scales are not added, and the scales are measured by a tool during installation.
When the test depth is required, the transmitting transducer 21 and the receiving transducer 22 slide on the bar body portion 11, the transmitting transducer 21 and the receiving transducer 22 are disposed on both sides or the same side of the slit according to the requirement, and the transmitting transducer 21 and the receiving transducer 22 can be accurately disposed at the required positions due to the scale on the bar body portion 11.
When the width is to be measured, the width measuring instrument 3 is disposed above the crack, and the width measuring instrument 3 can be accurately disposed at a desired position because the lever portion 11 has a scale.
The utility model discloses can be very convenient while to concrete surface shallow crack width and degree of depth measure.
The above embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes or modifications made by those skilled in the art should not be construed as departing from the scope of the present invention.
