Description

Technical Field

[0001] The utility model relates to the technical field of mortar detection devices, in particular to a mortar strength detection device for building construction. Background Art

[0002] In the field of housing construction, mortar strength is a key indicator of building quality. Currently, conventional mortar strength testing involves applying pressure to a cubic specimen measuring 70 mm in length, width, and height. The pressure at which the specimen breaks is then calculated using a specific method to determine the mortar strength.

[0003] Traditional mortar strength testing typically involves applying pressure to the sample using a specific pressure device. This device typically consists of a base, a support, and a pressure mechanism. The pressure mechanism applies pressure to the sample placed on the base to detect its failure under the pressure, thereby determining the mortar's strength.

[0004] However, traditional testing equipment has some significant drawbacks. First, there is a lack of effective clamping and fixation of the sample. During the pressure application process, the sample is prone to displacement, affecting the accuracy of the test results. Second, the plate-shaped clamps used in traditional equipment will affect the strength of the sample, making it difficult to damage the sample, resulting in inaccurate test results. In addition, the fixed height of the clamping plate will affect the downward movement of the lower pressure plate, limiting the flexibility of the equipment and the detection efficiency.

A plurality of insertion cavities 7 are provided inside the slider 4, and a limit rod 6 is provided at the upper end of the insertion cavity 7 for plugging and connecting. A limit plate 8 is fixed on one end of the limit rod 6 extending into the interior of the insertion cavity 7, and a spring 9 is provided between the limit plate 8 and the bottom surface of the inner cavity 7.

[0033] In this embodiment, as a preferred technical solution, the bidirectional drive mechanism includes a bidirectional screw rod 10 rotatably arranged at the bottom of the platform 3, and also includes a rotating wheel 11 fixedly arranged at one end of the bidirectional screw rod 10. The two sides of the center of the bidirectional screw rod 10 are symmetrically threadedly connected with threaded sleeves 12, and the two sliders 4 are respectively fixed at the upper ends of the two threaded sleeves 12.

[0034] In this embodiment, as a preferred technical solution, both side walls of the through slot 5 are provided with sliding grooves 13 , and both the front and rear sides of the slider 4 are fixed with sliders 14 that slide in matching with the sliding grooves 13 .

[0035] In this embodiment, as a preferred technical solution, the pressure monitoring mechanism includes four pressure sensors 15 fixed on the upper end surface of the platform 3, and also includes a controller 16 fixed on the upper end surface of the base 1 for recording and monitoring the pressure value when the sample is destroyed.

[0036] In this embodiment, as a preferred technical solution, the pressure mechanism includes an electric push rod 17 fixed to the upper end surface of the bracket 2, and the piston end of the electric push rod 17 extends to the end below the bracket 2 and is fixed with a lower pressure plate 18.

[0037] In this embodiment, as a preferred technical solution, the leveling mechanism includes leveling foot cups 19 fixed at the four corners of the bottom of the base 1 , and also includes a bubble level 20 fixed on the front and side of the base 1 .

[0038] The working principle of the utility model of a house construction mortar strength detection device is as follows: first, the device is adjusted to a horizontal state by the leveling mechanism at the bottom of the base to ensure the accuracy of the detection. After the mortar sample to be tested is placed in the center of the platform, the bidirectional drive mechanism drives the slider to move, so that the vertical limit rod on the slider extends under the action of the spring to clamp and fix the sample. After the pressure mechanism at the upper end of the bracket is started, the electric push rod pushes the lower pressure plate to move downward. When it contacts the limit rod, the lower pressure plate presses down, causing the limit rod to overcome the elastic force of the spring and move downward, continuously applying pressure to the sample. As the pressure continues to increase, when the pressure reaches a certain level, the sample is destroyed. At this time, the pressure monitoring mechanism on the upper end face of the platform records the pressure value when the sample is destroyed, and the strength of the mortar can be obtained according to a specific calculation method.

[0039] The working process of the utility model of a housing construction mortar strength detection device is as follows:

[0040] 1. Leveling device: Observe the bubble level 20 on the front and side of the base 1, and adjust the leveling feet 19 at the four corners of the bottom of the base 1 to ensure that the device is in a horizontal state.

[0041] 2. Place the sample: Place a cube mortar sample with a length, width and height of 70 mm on the center of the upper end surface of platform 3.

[0042] 3. Clamping the Sample: Rotating the wheel 11 at one end of the bidirectional screw 10 moves the threaded sleeve 12, which in turn moves the slider 4, which is fixed to the upper end of the threaded sleeve 12, toward the sample. The vertical limit rod 6 inside the slider 4 extends under the action of the spring 9, clamping the sample.

[0043] 4. Start the pressure mechanism: Start the electric push rod 17 on the upper end of the bracket 2. The piston end of the electric push rod 17 pushes the lower pressure plate 18 downward. When the lower pressure plate 18 contacts the limit rod 6, the limit rod 6 is compressed to overcome the elastic force of the spring 9 and retract downward.

[0044] 5. Monitoring pressure: Under the action of pressure, the sample is gradually destroyed. Four pressure sensors 15 on the upper end surface of the platform 3 record and monitor the pressure value of the sample during destruction in real time and transmit the data to the controller 16.

[0045] 6. Calculate the strength: Based on the pressure value recorded by the pressure sensor 15, the strength of the mortar is obtained through a specific calculation method.

[0046] 7. Cleaning device: After the test is completed, the wheel 11 is rotated in the opposite direction to release the sample from the slide 4. The residue on the platform 3 is cleaned to prepare for the next test.

[0047] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
