Abstract
The utility model relates to a foldable reinforced concrete thickness measurement instrument for building engineering, which is characterized in that the foldable reinforced concrete thickness measurement instrument comprises a test rod with graduations, a rotary shaft and a telescopic handle, wherein the test rod with the graduations is connected with the telescopic handle through the rotary shaft. Compared with the prior art, the foldable reinforced concrete thickness measurement instrument has the advantages that the foldable reinforced concrete thickness measurement instrument has a simple structure and is convenient in use and carrying. With the adoption of the foldable reinforced concrete thickness measurement instrument, the thickness of a reinforcement protective layer at any time can be detected, a thickness value of the protective layer is ensured to be in a design range, and the oversize or undersize of the protective layer is effectively avoided.
Description
Technical field
The utility model relates to concrete thickness tester in a kind of construction work, particularly relates to a kind of collapsible reinforced concrete thicknessmeter.
Background technology
The thickness of protection tier test is an indispensable link in the construction work, and whether protective layer thickness can reach design load, directly has influence on the construction quality of buildings.If protective seam is excessive, the sectional area of framework of steel reinforcement is just reduced, and bearing capacity also diminishes thereupon; If protective seam is too small, the time limit of concrete carbonization is with reduced, and the life-span of buildings also is shortened thereupon simultaneously.
In construction in the past, basic employing is tied up concrete pad, is relied on construction experience, formwork to control the thickness of protective seam, and the easy Da Yi of the thickness of protective seam is little like this, is difficult to guarantee.
Summary of the invention
The purpose of this utility model provides a kind of easy to operate, collapsible accurately reinforced concrete thicknessmeter of test number.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of collapsible cover to reinforcement thicknessmeter is characterized in that, comprises reference test bar, turning axle and the extendable handle of being with scale, and the reference test bar of band scale is connected by turning axle with extendable handle.
Compared with prior art, the utility model has the advantages that: simple in structure, easy to use, be easy to carry.Can detect the thickness of cover to reinforcement at any time, the one-tenth-value thickness 1/10 of guaranteeing protective seam is effectively stopped the excessive or too small of protective seam in scope of design.
Description of drawings
Fig. 1 is a unfolding assumption diagram of the present utility model;
Fig. 2 is foldable structure figure of the present utility model.
Among the figure: the reference test bar 2-extendable handle 3-turning axle of 1-band scale
Embodiment
See Fig. 1, Fig. 2, a kind of collapsible cover to reinforcement thicknessmeter comprises reference test bar 1, turning axle 3 and the extendable handle 2 of being with scale, and the reference test bar 1 of band scale is connected by turning axle 3 with extendable handle 2.
During work, the unfolded chi in the reference test bar 1 insertion concrete with the band scale, can directly be read tested concrete one-tenth-value thickness 1/10 by the scale on the reference test bar.The turning axle adjustable extent is 0 °-180 °; The adjustable in length of extendable handle 2 can be surveyed protective layer thickness value at a distance when stretching out.
