[0002] Flexural strength is one of the important indicators for measuring the bending performance of concrete materials, and it has a significant impact on the safety, durability, and service life of engineering structures. Flexural strength testing is one of the fundamental methods for concrete quality inspection and evaluation, and it plays an irreplaceable role, especially in important infrastructure projects such as bridges, floor slabs, and roads.

[0003] Traditionally, when testing the flexural strength of a concrete column, it needs to be placed on two supports, and then a hydraulic cylinder pushes a pressure seat to squeeze the suspended part of the concrete column for testing.

[0004] However, since concrete columns are not all standard square shapes, they are prone to sliding and rolling when subjected to external pressure, which seriously affects the accuracy and stability of the testing work. Moreover, the displaced concrete columns are prone to falling and injuring staff, posing a strong safety hazard.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 4This utility model provides an embodiment of a high-efficiency concrete flexural strength testing tool for engineering testing, comprising a support frame 1 for supporting the overall device. Support piers 2 are fixedly connected to the upper surface of the support frame 1. Two sets of support piers 2 are symmetrically distributed about the center line of the support frame 1. A hydraulic cylinder 3 is installed on the lower surface of the support frame 1, positioned in the middle of the lower surface to maintain centered pressure. The hydraulic cylinder 3 is existing technology and can be implemented by those skilled in the art; therefore, it will not be described in detail in this case. A load-distributing beam 4 is fixedly connected to the lower surface of the hydraulic cylinder 3. A pressure seat 5 is installed on the lower surface of the load-distributing beam 4, and the pressure seat 5 is fixed to the lower surface of the load-distributing beam 4 by bolts. Both the pressure seat 5 and the lower surface of the load-distributing beam 4 have threaded grooves. A positioning component is provided on the upper surface of the support frame 1, facilitating the clamping and fixing of concrete columns of different types. A quick-release component is provided on the upper surface of the pressure seat 5, facilitating the disassembly and installation of the pressure seat 5.

[0033] Reference Figure 1 - Figure 3 The positioning component includes an electric push rod 61, which is existing technology and can be implemented by those skilled in the art. As it is existing technology, it will not be described in detail in this case. A connecting plate 62 is fixedly connected to the upper surface of the electric push rod 61. The electric push rod 61 can drive the connecting plate 62 to move longitudinally. A positioning plate 64 is slidably connected through the front surface of the support 2. A clamping block 65 is fixedly connected to the rear surface of the positioning plate 64. The clamping block 65 is cylindrical and located at the top of the rear surface of the positioning plate 64. A sliding rod 66 is fixedly connected to the right surface of the positioning plate 64. A moving plate 63 is slidably connected to the right surface of the support 2. The moving plate 63 moves longitudinally. An inclined groove 601 is opened on the right surface of the moving plate 63. The positioning plate 64, clamping block 65, sliding rod 66 and inclined groove 601 are all provided in two sets, which are symmetrically distributed about the center line of the support 2.

[0034] Reference Figure 1 , Figure 4 The quick-release assembly includes a locking block 71. The inner wall of the locking block 71 is elastically connected to a limiting block 73 via a compression spring 72. A locking groove 701 is provided on the lower surface of the load-distributing beam 4. The locking block 71 and the locking groove 701 fit together. A limiting groove 702 is provided on the inner wall of the load-distributing beam 4. The limiting block 73 and the limiting groove 702 fit together.

[0035] Reference Figure 1 - Figure 3An electric push rod 61 is installed on the upper surface of the support frame 1. A movable plate 63 is fixedly connected to the upper surface of the connecting plate 62. There are two sets of movable plates 63, which are symmetrically distributed on the left and right ends of the upper surface of the connecting plate 62 and are slidably connected to the support 2. The positioning plate 64 is L-shaped. A sliding rod 66 passes through and is slidably connected to the right surface of the support 2. The sliding rod 66 slides on the inner wall of the inclined groove 601. The outer wall of the sliding rod 66 is in contact with the inner wall of the inclined groove 601. The inclined groove 601 is opened in an inclined shape. When the inclined groove 601 moves, it will squeeze the sliding rod 66, thereby driving the two sets of sliding rods 66 to retract or open back and forth.

[0036] Reference Figure 1 , Figure 4 The locking block 71 is fixedly connected to the upper surface of the pressure seat 5 and inserted into the inner wall of the locking groove 701, which can initially position the pressure seat 5. The limiting block 73 is inserted into the inner wall of the limiting groove 702, which can stabilize the position of the pressure seat 5 and facilitate the tightening of bolts. One end of the compression spring 72 is fixedly connected to the rear surface of the limiting block 73, and the other end of the compression spring 72 is fixedly connected to the inner wall of the rear side of the locking block 71. The limiting block 73 is slidably connected to the front surface of the locking block 71. When the limiting block 73 moves backward, it will squeeze the compression spring 72 to generate a reaction force. The front surface of the limiting block 73 is set as an arc surface. When the arc surface of the limiting block 73 is squeezed, the limiting block 73 will move backward. When it moves a certain distance, the limiting block 73 will retract into the locking block 71 to release the obstruction. The locking groove 701 and the limiting groove 702 are connected.

[0037] Working principle: When using this device, firstly, according to the length and requirements of the concrete column, install the pressure seat 5 at the corresponding position below the load-distributing beam 4. When installing the pressure seat 5, first insert the locking block 71 and the locking groove 701. During insertion, the arc surface of the limiting block 73 will be squeezed, and the limiting block 73 will gradually retract into the locking block 71 to release the obstruction. In addition, the limiting block 73 will also squeeze the compression spring 72 to generate a reaction force. When the locking block 71 and the locking groove 701 are inserted, the limiting block 73 will be aligned with the limiting groove 702. The reaction force of the compression spring 72 will push the limiting block 73 and the limiting groove 702 to insert and position the pressure seat 5. At this time, the threaded hole on the pressure seat 5 and the load-distributing beam 4 will be aligned, which makes it convenient to use bolts to fix the pressure seat 5 on the load-distributing beam 4.

[0038] Once the pressure seat 5 is fixed, place the concrete column centered on the support frame 1 and rest both ends on the piers 2. At this time, activate the electric push rod 61 to move the connecting plate 62 and the moving plate 63 downwards. The downward-moving moving plate 63 will cause the inclined groove 601 to move downwards and squeeze the sliding rod 66. The sliding rod 66 will cause the clamping block 65 and the positioning plate 64 to move towards the center of the pier 2 to clamp and fix the concrete column, ensuring that the concrete column will not shift under the influence of external forces during the flexural test. After fixing, close the electric push rod 61 and activate the hydraulic cylinder 3 to move the load-distributing beam 4 and the pressure seat 5 downwards to apply pressure to the concrete column for the flexural test. After the test is completed, close the hydraulic cylinder 3 and then activate the electric push rod 61 to move the connecting plate 62 and the moving plate 63 upwards. The upward-moving moving plate 63 will cause the inclined groove 601 to squeeze the sliding rod 66 in the opposite direction, thereby causing the clamping block 65 and the positioning plate 64 to open and release the clamping and fixing of the concrete column. Then the concrete column can be removed.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
