Description

Technical Field

[0001] The invention relates to the technical field of highway bridge construction, in particular to a concrete strength detection device for highway bridge construction. Background Art

[0002] Highway bridge engineering refers to the planning, design, construction, maintenance, and repair of highway structures across waters, valleys, and all traffic passages. With the rapid development of transportation infrastructure construction, especially the rapid popularization of expressways and high-speed railways, higher requirements are placed on the construction quality of highway bridges. Concrete is the main material of bridge structure, and its strength directly affects the bearing capacity and service life of the bridge. Therefore, in the process of highway bridge construction, accurate detection of concrete strength is particularly important.

[0003] Based on the above, the inventors have found that the existing concrete strength testing device for highway bridge construction has the following main deficiencies. For example, when testing the concrete in the bridge, it is necessary to perform multi-point collision between the digital rebound tester and the concrete on the bridge surface and then take the average value to obtain the strength of the concrete in the bridge. The operation of multi-point testing is relatively cumbersome, and the average value must be calculated after testing the concrete, which increases the difficulty of testing the concrete of highway bridges.

The rebound tester can be fixedly installed in the installation frame through the end face of the top block, so that four rebound testers can perform concrete strength tests on the end faces of highway bridges at the same time.

The rebound detector 4 can be fixedly installed in the installation frame 121 through the end face of the top block 123, so that four rebound detectors 4 can perform concrete strength detection on the end face of the highway bridge at the same time.

[0024] Based on the above embodiment, the specific working principle is as follows: the top end face of the rebound detector 4 is inserted into the installation frame 121, and then the buffer spring 124 is reset to drive the top block 123 to move upward.
