[0002] Building construction refers to the production activities in the implementation stage of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations. It includes foundation engineering construction, main structure construction, roofing engineering construction, decoration engineering construction, etc. The place of construction is called "building construction site" or "construction site", also called construction site. In the process of building construction, it is necessary to supervise the construction progress and construction materials. Quality supervision refers to the continuous monitoring and verification of the status of products, processes or systems to ensure that the specified quality requirements are met, and the records are analyzed. For quality supervision, concrete testing devices are needed. Concrete testing devices are used to sample and test the quality and strength of concrete in the construction process.

[0003] In the process of using the existing concrete testing device for construction quality supervision, when performing concrete pressure testing, the current status of the sampled concrete is irregular, and whether the bonding plate can be bonded according to the plane angle of the sampled concrete during the testing process affects the force area when the subsequent bonding plate is pressed down. If the force area is uneven, the detected strength will naturally have a certain error, thereby affecting the accuracy of quality supervision testing. Therefore, it is necessary to propose a concrete testing device for construction quality supervision. Utility Model Content

[0013] 1. This concrete testing device for construction quality supervision is provided with a metal elastic ring, a fixed block, a movable telescopic rod, a rotating shaft, a fixed frame, a bonding plate and a damping reset rod. When the device is used to test sampled concrete, when testing concrete blocks of different shapes, the angle between the bonding plate and the movable telescopic rod can be adjusted by the rotating shaft and the fixed frame so that the bonding plate can be bonded to the surface of concrete blocks of different shapes to ensure the detection accuracy of the device. At the same time, after the bonding plate is pressed down, four groups of damping reset rods arranged above the bonding plate evenly distribute the force area of ​​the dispersion bonding plate, reduce the uneven force area, and allow the damping reset rod to drive the bonding plate to contract to complete the detection of concrete strength and improve the detection accuracy.

[0014] 2. This concrete testing device for construction quality supervision is provided with a strength tester, a test platform, a pressure sensor, a metal elastic ring, a pressure gauge, and a metal point contact. The pressure sensor connected to the strength tester wire senses the pressure strength of the concrete block on the test platform and can be displayed in real time from below for the operator to watch. At the same time, after the bonding plate is pressed down, the metal elastic ring is pressed and touches the metal point contact. The pressure gauge connected to the metal point contact can also detect the current pressure strength of the concrete block from above. In this way, the two different detection methods are used in combination to improve the accuracy of the device for concrete quality pressure detection and ensure the accuracy of quality supervision.

[0015] 3. This concrete testing device for construction quality supervision is equipped with a machine body, fixing bolts, a testing platform, a top plate, a hydraulic cylinder and a hydraulic rod.

The broken debris can be directly disassembled from the testing platform through the fixing bolts, and the inside of the testing platform can be cleaned to ensure the accuracy of the next test.

[0024] See also Figure 1 , Figure 3 , Figure 4 and Figure 5 The bottom of the detection pressure block 10 is fixedly connected with a metal elastic ring 11, and a pressure gauge 12 is arranged inside the metal elastic ring 11. A metal point contact 13 is fixedly installed on one side of the pressure gauge 12. After the bonding plate 18 is pressed down, the metal elastic ring 11 is subjected to pressure and touches the metal point contact 13 inside. The pressure gauge 12 connected to the metal point contact 13 can also detect the current pressure strength of the concrete block from above at this time. A fixed block 14 is fixedly installed at the bottom of the metal elastic ring 11, and a movable telescopic rod 15 is fixedly installed at the bottom of the fixed block 14.

[0025] Working principle: When using the concrete detection device for construction quality supervision, first turn on the external power supply, take out the concrete block to be tested and place it on the pressure sensor 5 of the detection platform 4, and then adjust the angle of the bonding plate 18 and the movable telescopic rod 15 through the rotating shaft 16 and the fixing frame 17, so that the bonding plate 18 can be bonded to the surface of concrete blocks of different shapes, then turn on the switch of the hydraulic cylinder 8, drive the power source of the hydraulic pump, the hydraulic pump presses the hydraulic oil into the hydraulic cylinder 8, drives the hydraulic rod 9 to descend, and the bonding plate 18 following the hydraulic rod 9 is bonded to the concrete surface. As the hydraulic rod 9 continues to descend, the bonding plate 18 applies pressure to the concrete block for pressure testing. At this time, after the bonding plate 18 is pressed down, the four groups of damping reset rods 19 arranged above the bonding plate 18 evenly distribute the force area of ​​the dispersion bonding plate 18 to reduce the uneven force area.
