In the detection project of the concrete, a concrete test block compression performance testing device is used.
[0003] The concrete test block compression performance testing device mainly comprises a machine table, an upper pressing plate, a pressure sensor, a placing table and a driving device. The pressure sensor is installed on the upper pressing plate. When performing pressure detection, the machine table is started, the driving device drives the upper pressing plate to apply pressure to the test block on the placing table until the concrete test block cracks, and then the compression strength of the concrete test block is calculated according to the pressure measured by the pressure sensor when the test block cracks. Thus, the test is repeated for multiple test blocks to determine whether the concrete is qualified.
[0004] During the test of multiple test blocks, the previous test block needs to be removed from the placing table, and the surface of the placing table needs to be cleaned to reduce the risk of uneven stress during the test, and the test block needs to be adjusted to be placed directly below the upper pressing plate. Each time the test block is replaced, it needs to be cleaned once, and the stress position of the test block needs to be adjusted again, which reduces the detection efficiency, and further improvement is needed. CONTENT OF THE INVENTION
[0005] In order to improve the detection efficiency, the present application provides a concrete test block compression performance detection device.
[0006] The concrete test block compression performance detection device provided by the present application adopts the following technical scheme:
[0007] A concrete test block compression performance detection device comprises an upper pressing plate, a placing table and a placing piece. The surface of the placing table is provided with a boss, the boss is located directly below the upper pressing plate, and the boss away from the surface of the placing table is used for abutting the placing piece. The placing piece is used for placing a single concrete test block. The area of the plane of the boss away from the placing table is smaller than the area of the plane of the placing piece abutting the surface of the boss.
[0008] By adopting the technical scheme, when the compressive performance of the concrete test block is detected, the concrete test block is placed on the placing piece, and then the placing piece is placed on the boss, so that the compressive performance detection can be performed. After the detection is completed, the placing piece carrying the concrete test block is taken down, the placing piece is turned over, the debris falls off, the concrete test block to be detected is placed on the placing piece, and the above operation is repeated, so that the detection of multiple concrete test blocks can be completed.

[0031] The following will be described in detail in combination with the accompanying drawings. Figures 1-3 The application is further described in detail.
[0032] The application discloses a concrete test block compressive performance detection device.
[0033] Referring to Figure 1 A concrete test block compressive performance detection device comprises a machine table, an upper pressing plate 1, a placing table 2, a placing piece 3 and a collecting tray 4. The machine table is provided with a driving device, the upper pressing plate 1 is installed on the driving device, and the driving device is used to drive the upper pressing plate 1 to move towards the placing table 2. The upper pressing plate 1 is provided with a pressure sensor. The placing table 2 is provided with a boss 5, and the placing piece 3 is placed on the boss 5. The placing piece 3 is used to place a single concrete test block. The collecting tray 4 is placed on the placing table 2 and is used to collect the debris of the broken concrete test block.
[0034] Referring to Figure 2 Specifically, the boss 5 is located directly below the upper pressing plate 1 and at the center of the placing table 2. The connection mode of the boss 5 and the placing table 2 can be detachable connection or fixed connection, which is not limited in the application. The shape of the boss 5 can be a cylinder, a cube, a cuboid or a polygonal prism, and in the embodiment, the shape of the boss 5 is a cuboid.
[0035] Referring to Figure 2 The placing piece 3 is provided with a rectangular shape corresponding to the planar shape of the boss 5. The planar area of the placing piece 3 abutting against the boss 5 is greater than the planar area of the boss 5 away from the placing table 2. When a single concrete test block is placed on the placing piece 3, the right angle of the concrete test block is located outside the placing piece 3. The four corners of the placing piece 3 are all welded and fixed with guide pieces 6. The guide pieces 6 are provided with grooves 61, which are adapted to the convex edges 51 of the boss 5. The guide pieces 6 can be made of angle steel, and the placing piece 3 is located at the middle part of the guide pieces 6. The placing piece 3 is provided with a circular ring 7, which is welded to each guide piece 6.
[0036] Referring to Figure 2 It is worth noting that when the convex edge 51 is located in the groove 61, the placing piece 3 is limited to be directly below the upper pressing plate 1, so as to realize the positioning of the concrete test block on the placing table 2.
[0037] Referring to Figure 2 and Figure 3The center of the collecting disc 4 is provided with a through hole 41 for the boss 5 to pass through. The edge of the through hole 41 is bonded and fixed with the elastic band 8. When the boss 5 passes through the through hole 41, the elastic band 8 is elastically deformed and covers the gap between the collecting disc 4 and the boss 5. The surface of the collecting disc 4 in contact with the placing table 2 is slidingly connected with the sliding sheet 9, which is used to cover the through hole 41. After the detection is completed, the collecting disc 4 is lifted, the sliding sheet 9 is slid, the through hole 41 is covered, and the debris of the broken concrete test blocks can be uniformly collected and treated.
[0038] The implementation principle of the concrete test block compressive performance detection device is that when the pressure detection is performed, the machine table is started, the driving device drives the upper pressing plate 1 to apply pressure to the test block on the placing sheet 3 until the concrete test block is cracked, then the compressive strength of the concrete test block is calculated according to the pressure borne by the test block when it is cracked measured by the pressure sensor. The machine table automatically releases pressure and drives the upper pressing plate 1 to lift and reset. The detection personnel hold the ring 7 with both hands, take out the cracked concrete test block together with the placing sheet 3, place them at the designated position, take out the concrete test block, turn over the placing sheet 3, and then place the concrete test block to be detected on the placing sheet 3, and then place the placing sheet 3 carrying the concrete test block on the boss 5 through the ring 7, and repeat the above steps to test multiple test blocks to determine whether the concrete is qualified. The application can not only quickly determine the placement position of the concrete test block, but also clean the placement position of the concrete test block by turning over the placing sheet 3, and the detection efficiency is high.
[0039] The above are preferred embodiments of the application, which do not limit the protection scope of the application. Therefore, any equivalent changes made according to the structure, shape and principle of the application should be covered within the protection scope of the application.
