Description

Technical Field

[0001] The utility model relates to the technical field of concrete testing, in particular to a concrete shrinkage testing device. Background Art

[0002] The limited expansion rate / contraction rate can be obtained by measuring the deformation of a one-way limiting device with a certain reinforcement ratio. The shrinkage rate of concrete is related to temperature and humidity. The higher the ambient temperature and humidity, the greater the temperature shrinkage rate of concrete. The limited expansion rate of the expansive agent is a key quality and technical indicator of the expansive agent product, and is determined according to the method specified in the current industry standard "Concrete Expansive Agent" JC476.

[0003] The existing published patent number is: CN206095136U, which discloses an automatic testing device for concrete expansion rate / contraction rate.

[0004] The above scheme saves man-hours and greatly improves efficiency. Compared with the existing traditional methods, it ensures the traceability of data. It can also automatically measure and store data by age and calculate the results, which provides convenience for the subsequent detection of concrete expansion rate / contraction rate. After the detection equipment is tested inside the concrete, there will be a lot of concrete residue on the surface. If it is not cleaned in time, it will adhere to the surface and it will be difficult to clean after solidification, resulting in the inability to use the detection device for a second time. When cleaning, the staff needs to clean the surface in time, which is very troublesome and wastes time. Utility Model Content

[0031] like Figure 1-4 As shown, the bottom of the outer surface of the movable plate 105 near the rectangular block 119 is fixedly connected to an electric push rod 107, and the bottom of the electric push rod 107 is fixedly connected to a block 108. The electric push rod 107 is started by power to push the block 108 and the square frame 109 to slide downward inside the slide groove 106.

[0032] like Figure 1-4 As shown, a slide groove 106 is provided on the outer surface of the movable plate 105, and a square frame 109 is slidably connected inside the slide groove 106. A limiting groove 110 is provided on the top of the outer surface of the square frame 109 to drive the detection device 112 into the interior of the concrete to detect the shrinkage rate.

[0033] like Figure 1-4 As shown, the block 108 is slidably connected to the inside of the limiting groove 110, and the inside of the frame 109 is fixedly connected with a test meter 111, through which the staff can observe the shrinkage rate of the concrete.

[0034] like Figure 1-4 As shown, a detection device 112 is fixedly connected to the bottom of the outer surface of the frame 109, and a motor 113 is fixedly connected to the top of the outer surface of the mixing tank 101. The detection device 112 enters into the interior of the concrete to detect the shrinkage rate. When the ambient temperature and humidity are higher, the temperature shrinkage rate of the concrete is greater.

After stirring, the scraper 115 is driven to rotate on the inner wall of the mixing tank 101 to clean the inner wall to prevent the concrete from adhering to the inner wall of the mixing tank 101.

[0036] like Figure 1-4 As shown, a motor 2 117 is fixedly connected to the top of the outer surface of the L-shaped plate 116, and a cam 118 is fixedly connected to the output end of the motor 2 117.

The higher the ambient temperature and humidity, the greater the temperature shrinkage rate of the concrete. The staff can observe the shrinkage rate of the concrete through the detection meter 111. When the electric push rod 107 drives the block 108, the frame 109 and the detection device 112 to move upward, a lot of concrete will adhere to the surface of the detection device 112. The motor 117 is started by the power supply to drive the convex plate 118 to rotate. The convex plate 118 rotates on the outer surface of the rectangular block 119.
