Technical Field

[0001] This utility model relates to the field of testing the stress performance of masonry blocks, specifically a testing device for the stress performance of autoclaved aerated concrete blocks. Background Technology

[0002] Autoclaved aerated concrete (AAC) blocks are porous concrete products made through processes such as batching and mixing, pouring, static curing, cutting, and high-pressure autoclaving. To ensure project quality, AAC blocks need to be tested using a stress performance testing device.

[0003] Chinese utility model patent CN216247974U discloses a performance testing device for autoclaved aerated concrete (AAC) blocks, comprising: a main body and an impact block, wherein the impact block is connected to the top inner side of the main body and is used to test the impact resistance of AAC blocks; and a test head connected to the impact block, with the bottom end of the test head having a conical structure. By installing the test head on the impact block, the impact resistance of local areas of AAC blocks can be tested, which is beneficial to improving the test results. The test head is easy to install and disassemble, making it convenient to use. Furthermore, a weight is added to the impact block to keep it balanced during use, and the impact force can be increased according to actual test requirements to obtain different data, making it highly practical.

[0004] However, existing testing devices for the stress performance of autoclaved aerated concrete (AAC) blocks have fixed installation positions and distances between test heads when local testing of AAC blocks is required. This makes it inconvenient to adjust the position of the test heads and to dispose of waste and place the test plates after the test. Therefore, we propose a new testing device for the stress performance of AAC blocks to solve the problems mentioned above. Utility Model Content

[0029] 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.

[0030] Example 1: Please refer to Figures 1-5 The existing test device for the stress performance of autoclaved aerated concrete blocks has a fixed installation position of the test head and a fixed distance between the test heads when it is necessary to conduct local testing on the autoclaved aerated concrete blocks. It is inconvenient to adjust the position of the test head. In order to solve this technical problem, this embodiment discloses the following technical content.

[0031] A test device for the stress performance of autoclaved aerated concrete blocks includes a base frame 1, a protective cover 8 and a protective door 9. A first hydraulic mechanism 2 is fixed inside the base frame 1, and a placement plate 3 is fixed at the output end of the first hydraulic mechanism 2. An intermediate plate 4 is fixed on the upper surface of the base frame 1. A hole is opened in the middle of the intermediate plate 4 for the placement plate 3 to pass through. The first hydraulic mechanism 2 drives the placement plate 3 to rise and fall, thereby adjusting the height of the autoclaved aerated concrete blocks on the placement plate 3.

[0032] The upper surface of the middle plate 4 is fixed with a second hydraulic mechanism 10 at both ends, and the output end of the second hydraulic mechanism 10 is fixed with a first stamping plate 11. The inner top wall of the protective cover 8 is fixed with a third hydraulic mechanism 14, and the output end of the third hydraulic mechanism 14 is fixed with a folded plate 15. The lower surface of the folded plate 15 is fixed with a second stamping plate 16. The second hydraulic mechanism 10 and the third hydraulic mechanism 14 are perpendicular to each other. The two sets of second hydraulic mechanisms 10 on the left and right drive the first stamping plate 11 to move and squeeze the autoclaved aerated concrete block in the horizontal direction. Under the action of the third hydraulic mechanism 14, the folded plate 15 and the second stamping plate 16 move downward and squeeze the autoclaved aerated concrete block in the vertical direction.

[0033] The top of the second stamping plate 16 is provided with an insertion hole 17, and the inside of the second stamping plate 16 is provided with an insertion rod 18. The bottom end of the insertion rod 18 is fixed with a second test head 19, and the outer end of the second test head 19 is threaded with a nut 20. The rear end of the insertion rod 18 is provided with a sliding groove 21, and the inside of the sliding groove 21 is provided with a positioning block 22. The insertion holes 17 are equally spaced inside the second stamping plate 16. The upper surface of the nut 20 is tightly fitted with the lower surface of the second stamping plate 16. The positioning block 22 is connected to the second stamping plate 16 through the insertion holes 17.

[0034] When local testing is required, insert rod 18 is placed inside the second stamping plate 16, with the top of insert rod 18 located on the second stamping plate 16. Insert rod 18 is slid inside the second stamping plate 16 to adjust its position. Then, the positioning block 22 is slid inside the slide groove 21 to align the positioning block 22 with the insertion hole 17. Next, insert rod 18 is moved downward to insert the positioning block 22 into the corresponding insertion hole 17. Then, nut 20 is threaded to the outer end of the second test head 19 to fix the second test head 19. Under the action of the third hydraulic mechanism 14, the folding plate 15, the second stamping plate 16, and the second test head 19 impact the test block downward.

[0035] The mounting bracket 12 is snapped into the inside of the first stamping plate 11, and then the front and rear positions of the autoclaved aerated concrete block are adjusted, or the height of the placement plate 3 and the autoclaved aerated concrete block is adjusted by the first hydraulic mechanism 2, so that the first test head 13 can impact different positions on the side of the test block.

[0036] Example 2: The technical content disclosed in this example is a further improvement based on Example 1. Existing autoclaved aerated concrete block stress performance testing devices are inconvenient for waste disposal and the placement of plate 3 after the test. To further solve this technical problem, this example discloses the following technical content: Figures 1-7 As shown;

[0037] A motor 5 is fixed to the front side of the base frame 1. A screw 6 is fixed to the output end of the motor 5, and a cleaning plate 7 is threaded to the outer end of the screw 6. After the test, the height of the placement plate 3 is lowered under the action of the first hydraulic mechanism 2, so that the placement plate 3 is lowered to below the cleaning plate 7. Then, the screw 6 is rotated under the action of the motor 5, so that the cleaning plate 7 moves. The movement of the cleaning plate 7 cleans the waste on the placement plate 3 and pushes the waste into the storage box 23. Since the upper surface of the cleaning plate 7 is in contact with the lower surface of the middle plate 4, and the part of the right end of the cleaning plate 7 that is in contact with the middle plate 4 is a rectangular structure, the rotation of the screw 6 will not drive the cleaning plate 7 to rotate, but can drive the cleaning plate 7 to move back and forth.

[0038] Storage box 23 is slidably installed inside the bottom frame 1. Storage box 23 can be pulled out from inside the bottom frame 1 to handle the waste inside storage box 23. During the test and waste handling process, the protective door 9 is closed. The protective door 9 can reduce noise and reduce environmental pollution.

[0039] The above completes a series of operations for the test device for the stress performance of autoclaved aerated concrete blocks. Any content not described in detail in this instruction belongs to the prior art known to those skilled in the art.

[0040] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
