Description

A compressive testing device for construction engineering

Technical Field

The utility model relates to the technical field of building material detection devices, in particular to a compression detection device for construction engineering.

Background Art

The compressive performance of building materials in construction projects is one of the important indicators of their quality and safety. Traditional compressive testing devices usually use a single point position for testing, that is, only one point of the building material is tested with pressure. However, this method has the following defects:

Local evaluation: Traditional devices can only perform compression tests on one point and cannot evaluate the compression resistance of different locations of building materials at the same time. In fact, different locations of building materials may have different compression resistance because their internal structures and material properties may be different or uneven. Therefore, the overall compression resistance of building materials cannot be fully understood through the test results of a single point.

Deviation of test results: When a building material undergoes a compression test, its surface stress will change, and the next compression test may result in deviation of the results. This is because the building material may undergo slight deformation or stress distribution adjustment after being subjected to pressure, causing the results of subsequent tests to deviate from the actual situation. These changes may affect the reliability of the building material and the accuracy of the test results.

Utility Model Content

The utility model provides a compression testing device for construction engineering, aiming to solve the defect that the traditional compression testing device can only detect one point at a time, which causes the deviation of the testing result.

In order to solve the above technical problems, the technical solution of the utility model is: a compression detection device for construction projects, including a base, four columns are fixedly provided on the upper end surface of the base, a top plate is fixedly provided between the upper ends of the four columns, an electric push rod is fixedly provided on the upper end of the top plate, a lifting plate is fixedly provided on the end of the electric push rod extending below the top plate, a plurality of compression detection components are fixedly provided on the lower end surface of the lifting plate, a horizontal scale is slidingly sleeved between the four columns, vertical scales are fixedly provided on the left and right sides of the upper end of the base, the vertical scale passes through the horizontal scale and is slidably connected to the horizontal scale, and a limiting mechanism is matched between the horizontal scale and the vertical scale.

Furthermore, the pressure detection component includes a column fixed on the lower end surface of the lifting plate, a pressure detection ball is movably provided at the lower end of the column, and a pressure sensor is provided between one end of the pressure detection ball extending into the interior of the column and the top surface of the interior of the column.

Furthermore, it also includes an external control panel for displaying and recording pressure values, and the plurality of pressure sensors are electrically connected to the external control panel.

Compared with the prior art, the utility model has the following advantages:

1. Multi-point detection: The device uses multiple compression test components, which allows pressure to be applied to different positions of the building materials for testing at the same time. By analyzing and synthesizing the test results at different positions, the overall compression performance of the building materials can be evaluated more comprehensively and accurately.

2. Automatic control: The device is equipped with an electric push rod and a lifting plate, which can achieve automatic lifting and maintain stable contact between the detection component and the surface of the building material. This ensures that the experimental conditions are consistent during each test, reduces the interference of external factors on the results, and improves the accuracy and repeatability of the test.

3. Pressure sensor: A pressure sensor is installed inside the compression test component to accurately measure the pressure on the building materials. At the same time, multiple pressure sensors are electrically connected through an external control panel to display and record test results in real time, making it convenient for operators to analyze and record data.
