Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.
Fig. 1-4 illustrate an embodiment of the present invention.
As shown in fig. 1-4, the detecting device of the present embodiment includes an outer cylinder 1, a pull rod 2 and a digital height gauge 3.
The outer cylinder 1 is made of a galvanized pipe with the diameter DN15, and the upper end and the lower end of the outer cylinder 1 are respectively provided with an upper hole and a lower hole; an upper positioning rod 4 with the thickness of 3mm is welded at the upper end of the outer cylinder 1 along the transverse direction, and a lower positioning rod 5 with the thickness of 3mm is welded at the lower end of the outer cylinder 1 along the transverse direction; the outer end parts of the upper positioning rod 4 and the lower positioning rod 5 are both conical;
the drawing rod 2 penetrates through the outer cylinder 1 through the upper hole and the lower hole and can slide up and down along the outer cylinder 1; scales are arranged at the upper part of the pull rod 2, and the reading number of the scales is gradually increased from bottom to top;
the digital display height gauge 3 is 0-5cm in accuracy, the upper portion of the digital display height gauge is fastened on the drawing rod 2 through the clamp 6, the digital display height gauge 3 is arranged in parallel with the drawing rod 2, and the lower end of the digital display height gauge 3 is in contact with the upper surface of the upper positioning rod 4.
Further, the screw hole and the nut 7 corresponding to the upper hole and the lower hole of the outer barrel 1 are arranged on the inner lower portion of the outer barrel 1, the distance between the nut 7 and the lower end of the outer barrel 1 is 10cm, the screw hole of the nut 7 and the three upper holes and the three lower holes of the outer barrel 1 are located on the same vertical line, and therefore the drawing rod 2 sequentially penetrates through the upper hole of the outer barrel 1, the screw hole and the lower hole of the outer barrel 1, and the drawing stability of the drawing rod 2 is improved.
Furthermore, the upper end of the drawing rod 2 is provided with a nut plug 8, so that the drawing rod 2 is prevented from slipping when being drawn up and down.
The method of use of this example is as follows:
s1, when the lower end of the pull rod 2 is aligned with the upper surface of the lower positioning rod 5, the reading of the correction digital display height gauge 3 is 0.00mm, and the zero scale on the pull rod 2 is aligned with the upper surface of the upper positioning rod 4;
s2, drawing the drawing rod 2, and checking whether the scale reading on the drawing rod 2 aligned with the upper surface of the upper positioning rod 4 is consistent with the reading of the digital display height gauge 3;
s3, after the positions are consistent, vertically putting down the detection device along the gap position of the beam plate, and rotating the outer cylinder 1 to enable the lower positioning rod 5 to be inserted into the outermost reinforcing steel bars at the lower part of the beam plate; the drawing rod 2 is made to fall freely or drawn manually, and the local part is drawn up and down to check whether a gap exists;
s4, after no gap exists, the lower end of the pull rod 2 is aligned with the upper surface of the lower positioning rod 5, so that the pull rod 2 falls freely, and the reading of the steel bar protection layer can be obtained.
The above is only the embodiment of the present invention, not the limitation of the patent scope of the present invention, all the equivalent structures made by the contents of the specification and the drawings are directly or indirectly applied to other related technical fields, all the same principle is within the patent protection scope of the present invention.
