Description

Technical Field

[0001] The utility model relates to the field of concrete detection, in particular to a concrete strength detection device. Background Art

[0002] Concrete strength detection is one of the items for inspecting the quality of concrete. There are many existing methods and devices for concrete strength detection, including the detection device shown in Figure 1 As shown, the detection device is composed of a rebound hammer and a detection head. The problem with this technical solution is that when using a rebound hammer to detect the strength of concrete, after the detection head touches the pitted or uneven concrete, it is easy to cause deviations in the detection results, or due to improper manual operation by the staff, the detection head does not make perpendicular contact with the concrete, which may also lead to inaccurate detection results, and it is relatively inconvenient to use. Content of the Utility Model

[0003] The purpose of the utility model is to solve the following problems existing in the prior art: when using a rebound hammer to detect the strength of concrete, after the detection head touches the pitted or uneven concrete, it is easy to cause deviations in the detection results, or due to improper manual operation by the staff, the detection head does not make perpendicular contact with the concrete, which may also lead to inaccurate detection results, and it is relatively inconvenient to use.

[0004] To solve the problems existing in the prior art, the utility model provides a concrete strength detection device, including a rebound hammer and a detection head. A detection head is provided on one side of the rebound hammer, connectors are provided on both sides of the rebound hammer, springs are provided inside the connectors, connection blocks are provided between both sides of the rebound hammer and the springs, a detection seat is provided on one side of the connector, and a spirit level is provided on the top of the detection seat.

[0005] Furthermore, a detection hole is provided inside the detection seat, and the position of the detection hole corresponds to that of the detection head. By squeezing the rebound hammer, the rebound hammer and the detection head are displaced towards the concrete wall surface. The detection head passes through the detection hole of the detection seat and squeezes the concrete wall surface, and the strength of the concrete wall surface can be detected by observing the rebound value.

[0006] Furthermore, an indicator is provided on the top of the detection seat, and the indicator is electrically connected to the spirit level. After the staff presses the detection seat against the wall surface, the horizontality of the concrete wall surface is detected through the signal fed back by the cooperation of the spirit level and the indicator, ensuring the accuracy of subsequent detection work.

[0007] Furthermore, one end of the connecting block is connected to the spring, and the other end of the connecting block is fixedly connected to the rebound instrument. By squeezing the rebound instrument, the rebound instrument and the detection head are displaced towards the concrete wall surface, and the connecting block follows the displacement to squeeze the spring. When the detection is completed, the staff releases the rebound instrument, and the spring that loses the extrusion force rebounds to drive the connecting block and the rebound instrument to reset, thus facilitating the next detection work.

[0008] Furthermore, an adjustment groove is provided inside the connecting piece, and the length of the spring is adapted to the length of the adjustment groove. The adjustment groove is used for installing the spring and for adjusting the displacement of the connecting block.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0010] After the staff of the present utility model presses the detection seat against the wall surface, the horizontality of the concrete wall surface is detected through the signal fed back by the level gauge in cooperation with the indicator, ensuring the accuracy of the subsequent detection work. During the detection process, the design of the detection seat, the connecting piece, the spring and the connecting block can play an auxiliary limiting effect on the rebound instrument, avoiding the situation that the rebound instrument is not in vertical contact with the concrete due to improper operation, resulting in inaccurate detection results. When the detection is completed, the staff releases the rebound instrument, and the spring that loses the extrusion force rebounds to drive the connecting block and the rebound instrument to reset, thus facilitating the next detection work and increasing the practicability of the device.

A connecting block 9 is provided between both sides of the rebound hammer 1 and the spring 7. One end of the connecting block 9 is connected to the spring 7, and the other end of the connecting block 9 is fixedly connected to the rebound hammer 1.

[0020] Working principle description: The staff holds the rebound hammer 1 to the concrete wall surface to be detected. Immediately after the detection seat 3 is closely attached to the wall surface, the horizontality of the concrete wall surface is detected through the signal fed back by the cooperation of the level 5 and the indicator 6. When the horizontality meets the standard, the staff can squeeze the rebound hammer 1 for detection. By squeezing the rebound hammer 1, the rebound hammer 1 and the detection head 2 are displaced towards the concrete wall surface, and the connecting block 9 follows the displacement to squeeze the spring 7. The detection head 2 passes through the detection hole 4 of the detection seat 3 to squeeze the concrete wall surface. By observing the rebound value, the strength of the concrete wall surface can be detected. During the detection process, the design of the detection seat 3, the connectors 8, the spring 7, and the connecting block 9 can play an auxiliary limiting effect on the rebound hammer 1, avoiding the situation where the rebound hammer 1 is not in perpendicular contact with the concrete due to improper operation, resulting in inaccurate detection results. When the detection is completed, the staff releases the rebound hammer 1, and the spring 7 that loses the extrusion force rebounds to drive the connecting block 9 and the rebound hammer 1 to reset, thus facilitating the next detection work.
