[0037] The following is combined Figures 1 to 3 This invention provides a detailed description of the pier protective layer testing fixture.

[0038] like Figure 1 and Figure 2 As shown, a specific embodiment of this utility model provides a pier protective layer inspection fixture. This pier protective layer inspection fixture includes a main inspection plate 100 and a handheld component 200. The main inspection plate 100 has a right-angled trapezoidal structure; the upper side of the main inspection plate 100 is the upper base of the right-angled trapezoidal structure, and the lower side of the main inspection plate 100 is the lower base of the right-angled trapezoidal structure, with the length of the upper base being greater than the length of the lower base; the left side of the main inspection plate 100 is the right-angled side of the right-angled trapezoidal structure, and the right side of the main inspection plate 100 is the hypotenuse of the right-angled trapezoidal structure; multiple main scale lines 120 are provided on the front and / or rear sides of the main inspection plate 100, the main scale lines 120 being parallel to the upper base, and the multiple main scale lines 120 being spaced apart in the vertical direction. The handheld component 200 includes a connecting part 210 and a handheld part 220; the handheld part 220 is formed at the right end of the connecting part 210; the connecting part 210 is connected to the upper side of the main inspection plate 100.

[0039] In this embodiment, a right-angled trapezoidal main detection plate 100 is used to detect the thickness of the protective layer. The main detection plate 100 is vertically inserted between the pier formwork and the reinforcing steel. When the left and right sides of the main detection plate 100 contact the pier formwork and reinforcing steel, the main scale line 120 aligned with the upper edge of the pier formwork represents the thickness of the protective layer at that point. Compared to using a steel tape measure to detect the protective layer thickness, the detection fixture in this embodiment is obviously more convenient to operate and easier to read the thickness value. It solves the problems of inconvenient operation and large workload associated with using a steel tape measure to measure the pier protective layer thickness in the prior art. Furthermore, by providing a handheld component 220, the operator can easily hold the device, improving detection speed. The handheld component 220 can also be hung on the upper edge of the pier formwork, allowing one person to take photos of the pier for image preservation.

[0040] Furthermore, the main scale line 120 extends in the left-right direction, with its two ends intersecting the right-angled side and the hypotenuse, respectively. Specifically, the bottom edge of the main detection plate 100 is 1 cm long, the bottommost main scale line 120 is 2 cm long, and the lengths of adjacent main scale lines 120 differ by 1 cm from bottom to top. This facilitates reading and improves the convenience of data retrieval.

[0041] Furthermore, the multiple main scale lines 120 are different colors, further improving the ease of data reading.

[0042] Furthermore, the handheld component 200 is a rectangular plate. The handheld component 200 and the main detection plate 100 form an L-shaped structure.

[0043] In some embodiments, a pointer is provided on the front or rear side of the main detection plate 100. The pointer slides and engages with the main detection plate 100 in the left-right direction to better read the reading and improve the accuracy of the scale reading.

[0044] The thickness of the protective layer is considered to meet the design requirements if it falls within a tolerance range. For example, the design value for the protective layer thickness on the drawing may be 3 cm, but considering actual construction conditions, a thickness between 2.8 cm and 3.2 cm is considered to meet the design requirements. Using a method of directly adding a main scale line 120 to the main detection plate 100 to detect a 0.2 cm error would actually make readings inconvenient.

[0045] like Figure 2 As shown, in some embodiments, the pier protective layer inspection fixture also includes an auxiliary inspection ruler 300; the length of the auxiliary inspection ruler 300 is not greater than the length of its bottom edge, ensuring that when the auxiliary inspection ruler 300 is installed at any width position on the main inspection plate 100, the right side of the auxiliary inspection ruler 300 will not protrude from the right side of the main inspection plate 100. The width of the auxiliary inspection ruler 300 is less than the width between two adjacent main scale lines 120; the auxiliary inspection ruler 300 is detachably connected to the main inspection plate 100; an indicator line 320 is provided on the auxiliary inspection ruler 300; the indicator line 320 is vertically aligned with one of the main scale lines 120.

[0046] Taking the testing of a protective layer with a design thickness of 3cm as an example, in use, firstly, the auxiliary measuring ruler 300 is installed at the main scale line 120 representing the 3cm thickness, with the indicator line 320 of the auxiliary measuring ruler 300 aligned vertically with the main scale line 120 representing the 3cm thickness. Then, holding the handle 220, the main measuring plate 100 is inserted between the pier formwork and the reinforcing steel. Finally, when the main measuring plate 100 is held in place by the pier formwork and reinforcing steel, observe whether the upper edge of the pier formwork falls within the width range of the auxiliary measuring ruler 300. If so, it means the protective layer thickness meets the design requirements. If not, it means the protective layer thickness at this point does not meet the design requirements. Obviously, using the testing fixture provided in this embodiment can simplify the measurement process and make the operation more convenient.

[0047] Understandably, the width of the auxiliary detection ruler 300 is within the tolerance range of the protective layer.

[0048] Furthermore, the pier protective layer inspection fixture includes multiple auxiliary inspection rulers 300; the widths of the multiple auxiliary inspection rulers 300 are different. Auxiliary inspection rulers 300 with different widths can be selected according to actual needs to work in conjunction with the main inspection plate 100 to complete the inspection of the protective layer thickness.

[0049] In some embodiments, the auxiliary detection ruler 300 is detachably connected to the main detection plate 100 via a connecting component, or the auxiliary detection ruler 300 is magnetically connected to the main detection plate 100.

[0050] For example, a strip of iron is provided on the left end of the side of the main detection plate 100 facing the auxiliary detection ruler 300, and a magnet is provided on the auxiliary detection ruler 300, with the magnet magnetically connected to the iron strip. The strip of iron is embedded in the main detection plate 100, and the magnet is embedded in the auxiliary detection ruler 300.

[0051] For example, the connection component includes a plurality of first connectors 410 and a second connector; the second connector is detachably connected to the first connectors 410; the plurality of first connectors 410 are spaced apart in the vertical direction on the main detection plate 100, and the second connector is disposed on the auxiliary detection ruler 300.

[0052] Preferably, the first connector 410 can be a groove, and the second connector can be a protrusion.

[0053] Preferably, the first connector 410 can be a protrusion, and the second connector can be a groove.

[0054] Understandably, the groove and the protrusion are slightly interference-fitted. That is to say, when the protrusion is inserted into the groove, the operator needs to apply force to separate the protrusion from the groove.

[0055] like Figure 2 and Figure 3As shown, the auxiliary measuring ruler 300 further includes a transparent window 310 in the middle, with the indicator line 320 located within the transparent window 310. The transparent window 310 facilitates observation of the main scale line 120, ensuring that the main scale line 120 and the indicator line 320 are vertically aligned.

[0056] like Figure 2 As shown, the handheld component 200 further includes a placement slot 230, which is detachably assembled with the auxiliary measuring ruler 300. This facilitates carrying the auxiliary measuring ruler 300 and prevents it from being lost.

[0057] Furthermore, the handheld component 200 is provided with a door for closing or opening the placement slot 230.

[0058] like Figure 4 As shown, in some embodiments, the main detection board 100 includes multiple splicing units 110; the splicing unit 110 has a right-angled trapezoidal structure; adjacent splicing units 110 are detachably connected. The height of the main detection board 100 can be adjusted by increasing the number of splicing units 110 according to actual needs, to suit different measurement requirements and expand the applicability of the detection fixture.

[0059] Specifically, the joint between adjacent splicing units 110 can serve as the main scale line 120.

[0060] Furthermore, the lower side of the splicing unit 110 is provided with a slot 111 along the front-back direction, and the upper side of the splicing unit 110 is provided with a buckle 112 along the front-back direction. The buckle 112 and the slot 111 are engaged and assembled along the front-back direction. This facilitates assembly while ensuring that the buckle 112 and the slot 111 can slide and assemble in the front-back direction, while restricting the freedom of movement in the vertical and horizontal directions, thus preventing adjacent splicing units 110 from automatically detaching during use.

[0061] Understandably, when the latch 112 and the slot 111 are in the desired state, the vertical and horizontal degrees of freedom of adjacent splicing units 110 are restricted. In other words, two adjacent splicing units 110 can slide in the front-back direction. This prevents the splicing units 110 from automatically disengaging during use.

[0062] like Figure 5 As shown, in some embodiments, the pier protective layer inspection fixture further includes multiple inspection units and a telescopic unit 20; the multiple inspection units are arranged along the telescopic direction of the telescopic unit 20, and two adjacent inspection units are respectively connected to the two ends of the telescopic unit 20. By setting multiple inspection units and the telescopic unit 20, the inspection efficiency can be further improved.

[0063] Specifically, the telescopic unit 20 is connected to the handheld part 220.

[0064] Furthermore, the telescopic unit 20 is detachably connected to the detection unit. Specifically, the telescopic unit 20 is detachably connected to the handheld part 220.

[0065] Furthermore, the telescopic unit 20 includes, but is not limited to, a telescopic joint. The telescopic joint allows two adjacent detection units to move closer together or further apart.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
