Wherein, the bottom plate 1 is preferably paved into a horizontal base surface by adopting reinforced concrete materials; the top plate 2 is preferably formed into a rectangular frame structure with sufficient strength by electric welding process using section steel (longitudinal and transverse beams may be provided in the rectangular outer frame to improve the strength); the stay bar 3 is preferably a metal round tube, and may be a section steel. One end of the stay bar 3 is fixed on the bottom plate, and the other end is connected with the top plate 2. Preferably, the supporting rods 3 are respectively arranged near four top corners of the rectangular frame, so that the rectangular frame has better strength. The top plate 2 is substantially parallel to the bottom plate 1. The hydraulic cylinder 4 is suspended upside down and fixed at the midpoint of the roof panel 2. The hydraulic cylinder 4 comprises a base 41 fixedly mounted to the top plate 2 and a column 5 mounted to the base.

The hydraulic cylinder 4 and the pressure sensor 8 are connected to a control console 13. When the hydraulic cylinder 4 presses the concrete, the pressure sensor 8 can transmit the current pressure value to the console 13, and display the value on the console 13, thereby detecting the strength of the concrete. The control console 13 can also be used to control the raising and lowering of the hydraulic cylinder 4 (in practice, the extension and retraction of the upright 5, and therefore the raising and lowering of the pressure plate 6 and the pressure block body) and the sliding movement of the first and second support mechanisms 9 on the slide rails 14 (described in detail below).
The slide rail 14 is a linear steel rail, and the cross section of the slide rail is in a convex structure with a wide bottom and a narrow upper part. The preferable scheme is that the steel rail comprises at least two parallel linear steel rails. The first and second support mechanisms 9 are mounted on a slide rail 14 and are slidable on the slide rail 14 under the control of the console 13. For simplicity, it is preferred that the first and second support mechanisms 9 are identical in construction (for simplicity, only the construction of the first support mechanism 9 will be described below). The first supporting mechanism 9 comprises a base 10, a support column 11 and a supporting plate 12 which are stacked from bottom to top. The bottom of the base 10 is provided with a groove (not shown) corresponding to the slide rail 14, so as to facilitate the sliding of the first supporting mechanism 9 on the slide rail 14. The supporting plate 12 is provided with a fixing device (not shown) for fixing a concrete sample for bridge construction to be detected.

The utility model discloses can solve the concrete intensity under the different states according to the general algorithm of industry sector through the distance between two sets of supporting mechanism 9 of adjustment for the position of pneumatic cylinder 4 and two sets of supporting mechanism 9. When the group of supporting mechanisms 9 is positioned right below the hydraulic cylinder 4, the hardness of the concrete sample can be mainly tested; when the two groups of supporting mechanisms 9 are spaced at a short distance, the strength of the concrete sample can be mainly tested; when the distance between the two groups of supporting mechanisms 9 is far away, the detection of the shearing force and the comprehensive strength of the current concrete sample can be completed, and then the state of the concrete on the bridge in a long span can be simulated.

It is suitable for detecting the strength of the concrete sample. When the slide rail is at the third position (as shown in fig. 3), the hydraulic cylinder faces the midpoint of the connecting line of the vertical center lines of the first and second support mechanisms in the vertical direction, and the first and second support mechanisms 9 are far apart, i.e. the vertical center lines of the first and second support mechanisms are spaced apart from each other by a distance between three tenths and nine tenths of the total length of the slide rail (i.e. greater than or equal to three tenths and less than or equal to nine tenths).
