In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0021] like Figures 1 to 4 As shown, this embodiment provides a concrete elastic modulus test block positioning ruler, including a positioning ruler, the length of the positioning ruler is the same as the side length of the concrete elastic modulus test block 1, the width of the positioning ruler is half of the side width of the concrete elastic modulus test block, and a positioning notch 2 is provided on one of the long side edges of the positioning ruler for quickly marking the positioning screw position of the static elastic modulus meter under the test block.

[0022] In an embodiment of the utility model, the positioning ruler is composed of a main ruler 3, a first sub-rule 4, and a second sub-rule 5. The positioning notch is arranged on one of the long side edges of the main ruler, the other long side edge of the main ruler is hinged to one of the long side edges of the first sub-rule, and the other long side edge of the first sub-rule is hinged to one of the long side edges of the second sub-rule.

[0023] In an embodiment of the present invention, the lengths of the first secondary ruler and the second secondary ruler are equal to the length of the main ruler, and the widths of the first secondary ruler and the second secondary ruler are both half of the width of the main ruler.

[0024] In the embodiment of the utility model, the main ruler has a length of 300 mm and a width of 50 mm, and the first secondary ruler and the second secondary ruler have a length of 300 mm and a width of 25 mm.

[0025] In the embodiment of the utility model, the positioning notches are all in the shape of a semicircle.

[0026] In the embodiment of the utility model, the inner diameter of the positioning notch is 0.5 mm.

[0027] In the embodiment of the utility model, the number of the positioning notches is two.

[0028] In the embodiment of the utility model, the sizes of the concrete elastic modulus test block are of three types, namely:

[0029] Standard 150mm×150mm×300mm;

[0030] Non-standard 100mm×100mm×300mm, 200mm×200mm×300mm.

[0031] In the embodiments of the present invention, the positioning notches are all in the shape of a semicircle, and the center of the circle is located at one quarter and three quarters of the length of the main ruler, respectively.

[0032] In the embodiment of the utility model, the working principle of the concrete elastic modulus test block positioning ruler is:

[0033] 1. Determine the size of the positioning ruler: Before use, determine the size of the ruler according to the size of the concrete test block. For example, when testing the smallest concrete test block, the secondary ruler can be folded.

[0034] 2. Positioning mark points: Place the positioning ruler close to the concrete surface and use a pencil to draw positioning mark points at the positioning notch to facilitate the installation of the positioning screws of the elastic modulus meter.

[0035] 3. Install the elastic modulus: Install the elastic modulus on the prismatic concrete, and tighten the positioning screws of the elastic modulus to the marked points.

[0036] 4. Conduct elastic modulus test and record the test results.

[0037] The positioning ruler is simple in design and easy to operate. It is suitable for concrete elastic modulus test blocks of standard and non-standard sizes. Users do not need to perform tedious manual measurements, reducing the chance of human error. At the same time, rapid positioning significantly reduces test preparation time, improves work efficiency and measurement reliability.

[0038] The invention is used for quickly marking the position of the positioning screw of the elastic modulus instrument when testing the elastic modulus of concrete, and is particularly suitable for the scenario of testing a large number of test blocks.

[0039] Example 1: Non-standard test block with dimensions of 100 mm × 100 mm × 300 mm:

[0040] like Figure 3 As shown. When using the positioning ruler of the present invention to conduct a concrete elastic modulus test, the operator first places the main ruler part flat on the surface of the test block without unfolding the secondary ruler part. Then, place the secondary ruler close to the side wall of the concrete test block and use a pencil to mark the semicircular positioning notch. By repeating the same operation on the remaining three sides, the fixing point of the elastic modulus meter positioning screw can be quickly and accurately marked on the non-standard test block of 100mm×100mm×300mm. This method simplifies the traditional measurement process, improves work efficiency, and reduces errors introduced by manual marking.

[0041] Example 2: Standard test block with dimensions of 150 mm × 150 mm × 300 mm:

[0042] like Figure 4 As shown. When using the positioning ruler of the present invention to conduct a concrete elastic modulus test, the operator first unfolds the main ruler and the first secondary ruler at the same time and places them flat on the surface of the test block. Then, the second secondary ruler is placed close to the side wall of the concrete test block, and a pencil is used to mark the semicircular positioning notch. By repeating the same operation on the remaining three sides, the fixing point of the positioning screw of the elastic modulus meter can be quickly and accurately marked on the standard test block of 150mm×150mm×300mm. This method simplifies the traditional measurement process, improves work efficiency, and reduces errors introduced by manual marking.

[0043] The design of the first and second pairs of rulers allows them to serve as boundaries when measuring small-sized prismatic test blocks. After unfolding, they can meet the needs of the largest-sized prismatic test blocks, covering the full size range of test blocks (standard 150mm×150mm×300mm; non-standard 100mm×100mm×300mm, 200mm×200mm×300mm).

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
