Abstract
The utility model discloses a test template for measuring concrete compressive strength by a rebound method. Test holes are arranged on the surface of the test template. The number of the test holes is not less than 16, and is integral multiple of 16. Each of 16 test holes is a test area, and the area of each test area is not more 0.04 m2. The test hole can be of any shape, and the inscribed circle diameter of the test hole is not less than 10 mm and not more than 50 mm. The center distance of test holes should be greater than 20 mm, preferably 30 mm. The test template of the utility model is simple in operation, convenient in use, and measure points are uniformly and standardly distributed in the test area, and are easy to remove. Compared with conventional drawing grids on the concrete member surface, the surface under test is free of spots and pen marks, so the test template of the utility model is clean and environmental for measuring concrete compressive strength by the rebound method.
Description
Technical field
The utility model relates in particular to the concrete intensity with rebound method template used for testing about the concrete test device.
Background technology
In decades, the method for the detection concrete crushing strength of " rebound method " this suitable China's national situation has become the detection method of most widely used general, the most convenient of the on-the-spot in situ detection of China concrete works; Reisilometer has become requisite detecting instrument in quality control in China's engineering construction, quality supervision, the quality testing process, to improving China's construction quality Non-Destructive Testing level, guarantee that construction quality brought into play vital role, China has become the producing country of reisilometer maximum in the world and has used state.
Providing as follows for survey district and measuring point among the industry standard JGJ/T 23-2001 of the People's Republic of China (PRC) " concrete intensity with rebound method technical regulation ":
4.1.3 survey district's regulation
5 survey areas should not be greater than 0.04m
2
4.1.6 rebound value is measured
Measuring point should evenly distribute in surveying the district, and the clear distance of adjacent two measuring points should not be less than 20mm, and measuring point should not be less than 30mm apart from the distance of exposed steel bar, built-in fitting.Measuring point should or not expose on the stone at pore.Same measuring point is only answered attack once.Each is surveyed the district and keeps 16 rebound values in mind, and the rebound value reading of each measuring point should be estimated and reads 1.
According to the regulation of standard, when measuring, traditional way is to make marks with pen (chalk or red and blue pencil etc.) and ruler frame on test surfaces.Survey 16 lattice of district's picture at one, each lattice resilience once.But this kind way is loaded down with trivial details, owes standard, and person's handwriting should not be removed after the test, causes metope to pollute.
Summary of the invention
The purpose of this utility model is, overcomes the shortcoming and defect of prior art, and a kind of simple to operate, easy to use, standard environmental protection test template for concrete intensity with rebound method is provided.
The utility model is achieved by following technical solution.
The concrete intensity with rebound method template used for testing, its surface is provided with instrument connection, and described instrument connection is no less than 16, is 16 integral multiple, and per 16 instrument connections are one and survey the district that each survey area is not more than 0.04m
2
Described template adopts plastic plate, cardboard or metal sheet material to make.
The back side of described template is provided with gum, and gum can be point-like, wire, strip or planar distribution.
The shape of described instrument connection is circle, square, rectangle, triangle or trapezoidal; Circular diameter, the foursquare length of side, rectangular minor face length, triangle or trapezoidal inscribed circle diameter all are not less than 10mm, and are not more than 50mm.
The hole centre distance of described instrument connection is greater than 20mm.
16 gaging holes of each of described template are an elementary cell, and this template is the combination of one or two and two above elementary cells.
The both sides of described template or four limits are provided with binding or the fastener of being convenient to fix.
The beneficial effects of the utility model are, provide that a kind of simple to operate, easy to use, measuring point is evenly distributed in surveying the district, standard and be easy to remove, scribble lattice with tradition at surface of concrete structure and compare, the measured surface test is rear without spot, without person's handwriting, the test template that is used for concrete intensity with rebound method of clean environmental protection.

Fig. 4 is the test template synoptic diagram with a plurality of elementary cells field with "nine squares" formula.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
The utility model adopts the plastic plate, cardboard, metal sheet of different-thickness or is material with the sheet metal of steel wire.
As shown in Figure 1, the test template of the utility model concrete intensity with rebound method, its surface uniform or be provided with unevenly instrument connection, described instrument connection is no less than 16, be 16 integral multiple, per 16 instrument connections are one and survey the district that each survey area is not more than 0.04m
2
The back side of test template is provided with gum, is pasted on the surface of tested concrete component during for convenient the detection, and gum can be point-like, wire, strip or planar distribution.Also can adopt on both sides or four limits of template binding or fastener are set, be convenient to the usefulness of fixing test template.
Per 16 instrument connections of the present utility model are an elementary cell, can make the test template of an elementary cell, as shown in Figure 1.Also can make the test template by the tandem of several elementary cells combination, parallel, field with "nine squares" formula, such as Fig. 2, Fig. 3, shown in Figure 4.In a word, can carry out take elementary cell as unit combination in any.
The shape of the utility model instrument connection can be circular, also can be the arbitrary shapes such as square, rectangle, triangle, trapezoidal or polygon; Circular diameter, the foursquare length of side, rectangular minor face length, polygonal inscribed circle diameter are not less than 10mm, and are not more than 50mm.The hole centre distance of instrument connection should be greater than 20mm, and preferred hole centre distance should be less than 30mm.
