Detailed Description
The present utility model will be described in further detail with reference to the accompanying drawings.
The present embodiment is only for explanation of the present utility model and is not to be construed as limiting the present utility model, and modifications to the present embodiment, which may not creatively contribute to the present utility model as required by those skilled in the art after reading the present specification, are all protected by patent laws within the scope of claims of the present utility model.
Examples: the width test equipment for the concrete structure crack comprises a fixing frame 1, a starting sleeve 2, a distance measuring sleeve 3 and a lifting rod unit 5, wherein the fixing frame 1 is used for being installed on a concrete structure, the starting sleeve 2 and the distance measuring sleeve 3 are installed on the fixing frame 1, the starting section is arranged on a scale 4 on the starting sleeve 2, and the lifting rod unit 5 is arranged on the starting sleeve 2 and the distance measuring sleeve 3 and used for being inserted into the concrete structure crack. Referring to fig. 1 to 3, in the case of measuring the width of a crack existing on a concrete structure plane, a fixing frame 1 is placed on the plane, the fixing frame 1 has mounting feet, and can be fixed on the plane by itself, and then the width of the crack can be read out through a scale 4 by continuously adjusting the positions of an initial sleeve 2 and a ranging sleeve 3 so that a lifting rod unit 5 is aligned with the left and right sides of the crack. Because the position of the crack is generally more biased, for the convenience of measurement, the starting sleeve 2 and the distance measuring sleeve 3 can both freely move on the fixing frame 1, and the moving distance of the scale 4 and the starting sleeve 2 is consistent all the time, so that the problem of reading deviation can not be generated in the moving process.
The distance measuring sleeve 3 is provided with a mounting groove 301 for mounting the scale 4. Referring to fig. 4, one end of the scale 4 is fixed on the starting sleeve 2, and the other end is inserted into the mounting groove 301, and the height of the mounting groove 301 is identical to the height of the scale 4, so that the scale 4 always remains horizontal when the ranging sleeve 3 moves, and the reading is accurate.
The ranging sleeve 3 is provided with a fixing bolt 6. Preferably, the securing bolts 6 are respectively arranged on the starting sleeve 2 and the distance measuring sleeve 3. This allows the starting sleeve 2 and the distance measuring sleeve 3 to be fixed after their positions are adjusted, and improves the accuracy of the readings.
The lifter unit 5 includes a sleeve 501, a lifter 502 installed in the sleeve 501, and a positioning piece 503 provided at the bottom end of the lifter 502 for being embedded in a crack of a concrete structure. When it is difficult to visually inspect the crack through the scale 4 or when the crack faces some narrow cracks, the positioning pieces 503 can be inserted into the crack and close to two sides of the crack, and the width of the crack can be accurately read through the scale 4 by the relative positions of the starting sleeve 2 and the ranging sleeve 3.
The distance measuring sleeve 3 is further provided with an indication protrusion 302, and the indication protrusion 302 is vertically flush with the positioning sheet 503 arranged below the distance measuring sleeve 3. Referring to fig. 4, the cross section of the indicating protrusion 302 is a triangle, the tip of the triangle faces the scale position of the scale 4, and the vertical flush of the ranging sleeve 3 and the locating piece 503 specifically means that the tip of the triangle is vertically flush with one side edge of the locating piece 503 near the inner side face of the crack, so that the width of the crack can be accurately reflected.
The lifter unit 5 further includes a sliding slot 504 provided on the sleeve 501 and communicating with the inside, and an adjusting lever portion 505 installed in the sliding slot 504 and used for adjusting the height position of the lifter 502. Referring to fig. 5-6, the lifter 502 functions to change the position of the positioning plate 503 by moving outward from the sleeve 501, and the adjustment lever 505 can take the lifter 502 out by sliding in the sliding slot 504.
The adjustment lever portion 505 includes a slide lever 505a mounted in the slide slot 504, a pressing ring 505b provided at an inner end of the slide lever 505a, and a locking member 505c provided at an outer end of the slide lever 505a for pressing inward. The locking member 505c is typically a nut having an internal thread, and is screwed onto the external thread on the outer end of the sliding rod 505a, so that the locking member 505c presses the inner and outer walls of the sleeve 501 together with the pressing ring 505b by screwing, so as to achieve a locking effect on the sliding rod 505 a.
The connection manner of the lifter 502 and the adjusting lever 505 is divided into two types:
mode 1. The lifter unit 5 further includes a return spring 506 provided on the sleeve 501 for pulling back the lifter 502 inward, and the sliding rod 505a presses the lifter 502 outward. In this connection, the slide bar 505a is not connected to the lifter 502, but abuts against the inner end of the lifter 502, and the lifter 502 can be pressed outward when moved downward, and the lifter 502 is not pushed out of the sleeve 501 by the inward pulling action of the return spring 506, and the position of the lifter 502 is also fixed when the position of the slide bar 505a is fixed.
Mode 2. The inner end of the sliding rod 505a is fixedly connected to the side surface of the lifting rod 502. In this case, the movement of the slide bar 505a can be achieved by directly moving the slide bar 505 a.
The advantage of mode 1 is that when the positioning plate 503 is used, bending occurs, and thus when the reading is out of date, the lifting rod 502 needs to be detached from the sleeve 501 for convenient maintenance, and in the connection mode of mode 1, the lifting rod 502 is pulled out only by force and the connection relation between the lifting rod 502 and the return spring 506 is released, generally, the lower end of the return spring 506 is provided with a hook, and the hook is hooked at the mounting through hole at the inner end of the lifting rod 502, so long as the hook is detached. In mode 2, it is difficult to detach the lifter 502, and the fixing of the sliding rod 505a to the lifter 502 needs to be released, and in some cases, if the sliding rod 505a is welded to the lifter 502, the detachment process is not feasible. The mode 2 has the advantages of simple structure and convenience for factory manufacture.
Furthermore, wherever possible, the same or similar reference numbers are used in the drawings and the description to refer to the same or like parts or steps. The drawings are presented in simplified form and are not drawn to precise scale. For convenience and clarity only, directional terms, such as top, bottom, left, right, upward, above, below, rear and front, may be used with respect to the accompanying drawings. These and similar directional terms should not be construed to limit the scope of the disclosure in any way.
