[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0023] like Figure 1 As shown, a concrete flexural strength testing device includes: a universal testing machine 1, with a support platform 11 and an equipment space 12 at the bottom of the universal testing machine 1; a support adjustment mechanism 2 on the support platform 11; a temporary support mechanism 3 in the equipment space 12, the temporary support mechanism 3 including a telescopic rod 31 and a support frame 32, the support frame 32 passing through the support platform 11; a horizontal adjustment mechanism 4 on the side wall of the universal testing machine 1; a load transfer mechanism 5 connected to the universal testing machine 1; and a splash guard 6 in front of the universal testing machine 1.

[0024] The universal testing machine 1 can provide downward pressure loads and record the loads, displaying the flexural strength of the concrete specimens through data.

[0025] The support platform 11 is provided with two slide rails 111, which protrude from the surface of the equipment platform. The support platform 11 is provided with a slide 112 in the middle. The slide 112 is a rectangular through hole that passes through the top surface of the support platform 11. The slide 112 is located between the two slide rails 111. When the concrete bends, the debris generated falls from the slide 112 to the bottom of the universal testing machine 1.

[0026] like Figure 2The support adjusting mechanism 2 is used to support the bottom of the concrete test block, and includes a threaded rod 21, a handle 22 and two support blocks 23. The two support blocks 23 are slidably connected to the slide rail 111 at the two ends thereof, and are slidably connected to the slide 112 at the middle portion thereof. The bottom of each support block 23 is screwed with the threaded rod 21, and the handle 22 is arranged at one end of the threaded rod 21.

[0027] The bottom of each support block 23 is provided with a protrusion 231, and the threaded rod 21 penetrates through the protrusion 231. The threaded rod 21 is provided with a positive thread and a reverse thread. The other end of the threaded rod 21 is rotatably connected to the connecting base 113 arranged at the side of the slide 112. In use, the threaded rod 21 is rotated by rotating the handle 22. The protrusion 231 of one support block 23 is located on the positive thread, and the protrusion 231 of the other support block 23 is located on the reverse thread. When the threaded rod 21 is rotated, the two support blocks 23 are moved towards each other or away from each other. When the two support blocks 23 are moved, the distance between the two support blocks 23 and the midpoint of the support table 11 is always the same. When the concrete test block is placed in the middle and is pressed, the counterforce provided by the two support blocks 23 is the same.

[0028] The telescopic end of the telescopic rod 31 is arranged at the bottom of the support frame 32. The support frame 32 is provided with four support legs 321. The distance between the adjacent support legs 321 is less than the width of the concrete test block. When the concrete test block is placed, the telescopic rod 31 is first elongated, so that the top of the support leg 321 is higher than the top of the support block 23.

The friction between the ball 322 and the concrete test block is small. The test block is pushed on the ball 322, so that the test block is easily moved. Since the concrete test block does not press the support block 23 at this time, the position of the support block 23 can be quickly adjusted at this time, so that the support block 23 is in the accurate support position. The support leg 321 saves the labor of the test personnel to carry the test block to adjust the position, and improves the adjustment efficiency. When the position of the concrete test block is adjusted, the telescopic rod 31 is retracted, so that the support block 23 supports the concrete test block.

The push-pull rod 42 is provided with a scale line 421. After the concrete test block is placed on the supporting leg 321, two people stand on the two sides of the universal testing machine 1 and push the push-pull rod 42. After the push-pull rod 42 is pushed, the support frame 41 is attached to the side of the concrete test block, and then the two people determine the distance between the support frame 41 and the edge of the universal testing machine 1 according to the reading on the scale line 421 and adjust the push-pull rod 42. When the scales on the two push-pull rods 42 are consistent, the concrete test block reaches the centered placement state.

[0030] The load transmission mechanism 5 includes a loading head 51, a plug 52 and a loading seat 53, the loading seat 53 is provided with a plurality of slot positions, the loading head 51 is inserted into the slot position, and the plug 52 penetrates the loading head 51 and the loading seat 53. The loading head 51 is columnar as a whole, the bottom of the loading head 51 is lower than the loading seat 53, and when the loading head 51 is installed, the slot position where the loading head 51 is located is selected according to the predetermined loading position, and the plug 52 fixes the relative position of the loading head 51 and the loading seat 53. The top of the loading seat 53 is connected with the pressing end of the universal testing machine 1, the loading seat 53 transmits the pressure to the loading head 51, and the loading head 51 transmits the load to the concrete test piece, thereby completing the experiment on the concrete breaking strength.

[0031] The splash-proof curtain 6 is made of transparent material, the universal testing machine 1 is provided with a hook 13, and the hook 13 suspends the bottom of the splash-proof curtain 6.
