Description

Technical Field

[0001] This utility model relates to the field of concrete testing, specifically to a concrete material strength testing device. Background Technology

[0002] Concrete is the most common building material in daily construction projects. All kinds of buildings cannot do without the use of concrete. For different types of construction projects with different usage requirements, there are different specifications and parameter requirements for the strength of the concrete after completion. Therefore, testing the actual strength of various completed concrete buildings is an essential procedure in the construction process.

[0003] In existing technologies, the pendulum hammer test is commonly used for testing the strength of concrete materials. When using the pendulum hammer test, the testing device needs to be kept horizontal before inserting the test pin to obtain accurate results. However, in actual use, it has been found that leveling the testing device takes a long time, and after leveling, the test pin needs to be inserted into the device again. During the insertion of the test pin, the device needs to be held firmly against the concrete surface with one hand, which can easily lead to accidental slippage of the testing device, affecting the accuracy of the test. Alternatively, another person may be required to insert the test pin, which requires additional manpower and is inefficient. Utility Model Content

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0027] Example 1:

[0028] like Figures 1 to 7 As shown, this utility model provides a concrete material strength testing device, including a testing frame body 1 and a test seat 2 mounted on the testing frame body 1. The testing frame body 1 consists of a first support 101 and a second support 102 in the horizontal direction, and a handle 103 in the vertical direction for connecting the first support 101 and the second support 102. The test seat 2 has a test hole 3, and a test nail 4 is inserted into the test hole 3. The device also includes:

[0029] A hammering assembly is mounted on the first bracket 101. A hammer handle 5 is connected to the hammering assembly. A hammer head 6 is fixedly installed at one end of the hammer handle 5. The hammering assembly is used to drive the hammer head 6 to strike the side nail 4 from top to bottom in a free-fall state.

[0030] A leveling component is mounted on the first support 101 to adjust the horizontal position of the detection frame body 1.

[0031] A fixing component is provided on the handle 103. The fixing component includes a pressing plate 11 and an adsorption plate 12. The pressing plate 11 and the adsorption plate 12 are provided on the detection frame body 1. The pressing plate 11 is driven to press against the adsorption plate 12 so that the air in the adsorption plate 12 is discharged and fixed in the current position.

[0032] In use, first lift the hammer handle 5 upwards along the hammering assembly until the hammering assembly locks the hammer handle 5 in the current position. Then, press the test frame body 1 against the wall and level the test frame body 1 in the horizontal direction using the leveling assembly. Use the bubble level 10 on the first bracket 101 to determine whether the test frame body 1 is in a horizontal state. When the test frame body 1 is in a horizontal state, press the pressing plate 11 on the handle 103 to expel the air in the adsorption plate 12, making the adsorption plate 12 a vacuum state, and fix the test frame body 1 to the wall. At this time, the construction personnel can insert the test nail 4 into the test hole 3, release the hammering assembly from locking the hammer handle 5, and let the hammer handle 5 fall freely to strike and measure, and obtain the final test data.

[0033] Example 2:

[0034] like Figures 1 to 7 As shown, in conjunction with the technical solution of Embodiment 1, in this solution, the hammering assembly includes a U-shaped fixing part 13. A rotating shaft 14 is rotatably mounted through the upper part of the U-shaped fixing part 13, and the hammer handle 5 is fixedly mounted on the rotating shaft 14 inside the U-shaped fixing part 13. The concave part of the U-shaped fixing part 13 provides a space for the rotation of the rotating shaft 14, facilitating the fixed mounting of the hammer handle 5 on the rotating shaft 14. The hammer handle 5 can rotate within the space of the concave part of the U-shaped fixing part 13 as the rotating shaft 14 rotates.

[0035] Furthermore, a receiving groove 15 is provided on one side of the U-shaped fixing part 13, and an insertion hole 16 is provided on the rotating shaft 14 located in the receiving groove 15. A first spring 17 is fixedly installed on the side wall of the receiving groove 15, and a movable plate 18 is slidably installed in the receiving groove 15. The first spring 17 abuts against the movable plate 18. An insertion rod 19 is fixedly installed on the other end of the movable plate 18. The insertion rod 19 is adapted to the insertion hole 16. A slide rail 20 is provided on the side wall of the U-shaped fixing part 13, and a sliding column 21 is slidably installed in the slide rail 20. The sliding column 21 is fixedly installed with the movable plate 18. By manually rotating the hammer handle 5, the hammer handle 5 will drive the rotating shaft 14 to rotate synchronously until the insertion hole 16 on the rotating shaft 14 rotates to the insertion rod 19 in the receiving groove 15. The insertion rod 19 is inserted into the insertion hole 16 under the force of the spring, thus locking the rotating shaft 14. By manually pressing the sliding column 21, the sliding column 21 drives the moving plate 18 to compress the spring and move towards the bottom of the receiving groove 15. The moving plate 18 drives the insertion rod 19 to move towards the bottom of the receiving groove 15 together until the insertion rod 19 is separated from the insertion hole 16, releasing the lock on the rotating shaft 14. The hammer handle 5 then drives the hammer head 6 to fall freely.

[0036] Furthermore, the first bracket 101 has a receiving space. Two mounting brackets 22 are fixedly installed on opposite side walls of the first bracket 101. A rotating shaft 23 is rotatably connected between the two mounting brackets 22 on the same side. A rotating wheel 7 is fixedly installed on the outer side of the rotating shaft 23 near the handle 103, and a friction wheel 9 is fixedly installed on the outer side of the rotating shaft 23 away from the handle 103. Transmission wheels 8 are fixedly installed on the outer sides of both rotating shafts 23, and the two transmission wheels 8 are connected to each other by a belt 24. Holes are opened on opposite side walls of the first bracket 101, the shape and arrangement of which are adapted to the rotating wheel 7 and the friction wheel 9, respectively. The rotating wheel 7 and the friction wheel 9 are located inside the two holes. The operator drives the rotating wheel 7 to rotate using both thumbs. The rotation of the rotating wheel 7 is transmitted to the friction wheel 9 through the transmission wheel 8, causing the friction wheel 9 to rotate. The friction wheel 9 contacts the wall surface and can move on the wall, gradually adjusting the detection frame body 1 to a completely horizontal state.

[0037] Furthermore, a mounting block 25 is fixedly installed on the handle 103. A groove 26 is formed within the mounting block 25. The pressing plate 11 is slidably installed within the groove 26. A push rod 27 is slidably installed through the center of the bottom of the groove 26. The push rod 27 passes through the handle 103 and is slidably connected to it. One end of the push rod 27 is fixedly connected to the pressing plate 11. A second spring 28 is fitted around the push rod 27. Both ends of the second spring 28 abut against the bottom surface of the groove 26 and the bottom surface of the pressing plate 11, respectively. A pressure plate 29 is fixedly installed at the other end of the push rod 27. When the pressing plate 11 is pressed downwards, the pressing plate 11 drives the push rod 27 downwards during its downward movement. The push rod 27 then drives the pressing plate downwards. When the force applied to the pressing plate 11 is stopped, the pressing plate 11 is driven to return to its original position by the elastic force of the second spring 28.

[0038] Furthermore, a connecting frame 30 is fixedly installed on the handle 103. The connecting frame 30 is located within the space enclosed by the handle 103, the first support 101, and the second support 102. The connecting frame 30 consists of four connecting posts 301 and a connecting plate 302. One end of the connecting post 301 is fixedly connected to the handle 103, and the other end of the connecting post 301 is fixedly connected to the connecting plate 302. The adsorption plate 12 is fixedly installed on the connecting plate 302. The connecting plate 302 is fixed to the handle 103 by the connecting frame 30. The adsorption plate 12 is installed on the connecting plate 302. When the pressure plate moves downward, it abuts against the adsorption plate 12, expelling the air inside the adsorption plate 12. The adsorption plate 12 is in a vacuum state and adsorbs onto the wall surface. The connecting plate 302 is made of a soft material.

[0039] Furthermore, the bubble level 10 is fixedly installed at the center of the first bracket 101. The bubble level 10 can help determine whether the detection frame body 1 is in a horizontal state.

[0040] The working principle of a concrete material strength testing device disclosed in this application is as follows:

[0041] In use, hold the test frame body 1 with both hands and attach it to the wall. By manually rotating the leveling device and observing the bubble level 10 on the test frame body 1, gradually adjust the test frame body 1 to a horizontal state. Once the specific position of the test frame body 1 is determined, apply force to the pressing plate 11 to expel the air from the adsorption plate 12, creating a vacuum state inside the adsorption plate 12. Fix the adsorption plate 12 to the wall and fix the test frame body 1 to the wall using the connecting bracket 30. Insert the test nail 4 into the test hole 3 on the test base 2. At this time, manually lift the hammer handle 5 until it moves to the locked position. Manually engage the lock on the hammer handle 5 to allow it to fall freely and strike the test nail 4, completing the test. After the hammer head 6 stops swinging, measure the penetration depth of the test nail 4. The compressive strength or other mechanical properties of the tested material can then be calculated based on the predetermined formula.

[0042] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model.
