Description

Technical Field

[0001] The present invention relates to the technical field related to green concrete building material testing, and in particular to a compression testing device and a testing method for green concrete building materials. Background Art

[0002] Green concrete building materials are environmentally friendly building materials. Due to their characteristics of saving resources, reducing energy consumption and reducing pollution, they are widely used in fields such as roads, construction and ecological restoration. For example, building materials made from industrial waste generally have high compressive strength, high durability and waterproofness. They include high-performance concrete, recycled aggregate concrete and smart concrete. To ensure the service life of concrete building materials, they need to be subjected to compression tests before production and use to verify the quality of the concrete, ensure structural safety, control construction quality and evaluate durability and lifespan. The compression test first involves making test blocks and then using compression test equipment to test the test blocks. There are various compression test equipment and test methods for green concrete building materials on the market. For example, the announcement number CN208171756U discloses a simple device for measuring the compressive strength of concrete, including a box body; a base, a sensor and a test sample are arranged in sequence from bottom to top on the box bottom plate just below the upper box body; a press and a pressure head are respectively installed in relative sequence on the side surfaces of the left box body and the right box body away from the test sample; a motor is installed at a position close to the test sample on one side of the upper box body; one end of a connecting rod is fixedly connected to the output shaft of the motor; the utility model has a compact and simple structure and a reasonable design, not only has high accuracy in measuring the compressive strength of concrete, but also can monitor the anti-hammering strength of the test sample by hammering the upper part of the test sample, thereby achieving the dual-purpose purpose of a device, saving resources and killing two birds with one stone; and the conveyor belt and the pusher avoid the frequent manual handling of concrete test blocks, reducing the workload of the inspection personnel.

The semi-automatic modification device for concrete block compression test solves the problem that before the concrete compression test, the test block needs to be manually placed in the center area of ​​the universal pressure testing machine, and the test block needs to be manually taken out after the test is completed, which is labor-intensive, time-consuming and labor-intensive, and may injure the staff when it is broken, posing a safety hazard.

The compression test equipment for green concrete building materials according to claim 7, characterized in that: The cleaning mechanism comprises a fourth motor (27), an adjusting rod (28), an adjusting block (29), a shielding plate (30) and a push plate (31), wherein the output end of the fourth motor (27) is provided with an adjusting rod (28), and the outer side of the adjusting rod (28) is connected to the adjusting block (29) by a thread, the outer side slot of the adjusting block (29) is connected to the shielding plate (30), and the shielding plate (30) is fixed in the experimental equipment body (1), and a push plate (31) is welded below the adjusting block (29), and the inner cross section of the push plate (31) is an arc-shaped structure.

9. A test method for a compression test device for green concrete building materials according to claim 1, characterized in that: Test method for compression test equipment for green concrete building materials: Step 1: Place a test block of concrete building materials in the experimental equipment body (1), open the hydraulic rod (3), and move the pressure hammer (4) installed at the output end of the hydraulic rod (3) driver downward, so that the pressure hammer (4) applies pressure to the test block; Step 2: During the pressure application process, the multi-directional drive mechanism (9) symmetrically arranged on the left and right sides of the experimental equipment body (1) can be opened. A nozzle (8) is installed at the inner end of the multi-directional drive mechanism (9). The left nozzle (8) is connected to the water tank (6) and the water pump (7) to spray water mist, and the right nozzle (8) is connected to the air pump (21) to spray gas to simulate the compressive effect of concrete in a natural environment. Step 3: Open the hydraulic rod (3) to lift the pressure hammer (4), open the direction adjustment mechanism provided at the lower part of the experimental equipment body (1), and adjust the direction of the test block so that both sides of the test block can receive water mist and air flow; Step 4: After the test is completed, open the cleaning mechanism and clean the support seat (5).
