Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building thermal insulation material detection, in particular to a device for detecting the tensile and compressive properties of building thermal insulation materials. Background Technique
[0002] Building thermal insulation materials refer to the materials used in buildings to reduce heat transfer, maintain a stable indoor temperature, and save energy. These materials usually have a low thermal conductivity and can effectively isolate the heat exchange caused by the temperature difference between indoors and outdoors. Building thermal insulation materials can be classified in various ways according to their composition, shape, and use. Classified by material composition, common thermal insulation materials include rock wool, extruded polystyrene board (XPS), expanded polystyrene board (EPS), rubber and plastic thermal insulation materials, aluminum silicate thermal insulation materials, polyurethane foam, glass wool, etc.
[0003] During the production and processing of building thermal insulation materials, sampling and testing are required to detect their tensile and compressive properties. At present, the compressive and tensile tests of building thermal insulation materials are usually carried out separately, and transfer work is required during the process, which undoubtedly reduces the testing efficiency. Moreover, the position of the compressive testing structure cannot be adjusted, which easily leads to inaccurate test data. Content of the Utility Model
[0004] The purpose of the utility model is to provide a device for detecting the tensile and compressive properties of building thermal insulation materials, which has the advantages of high efficiency in detecting the tensile and compressive properties of building thermal insulation materials and can adjust the position of the pressure structure to improve the accuracy of compressive testing, and solves the problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A device for detecting the tensile and compressive properties of building thermal insulation materials, including an installation table and a threaded rod.

[0006] When using the device for detecting the tensile and compressive properties of building thermal insulation materials of the utility model,

A limiting sliding block is installed at the upper end of the movable block, and the limiting sliding block is slidably arranged in the limiting sliding groove.

[0010] Preferably, a driving device is installed at the side end of the support plate. The main shaft of the driving device is connected to the axis of the threaded rod. By operating the driving device, the threaded rod can rotate clockwise or counterclockwise. When the threaded rod rotates clockwise or counterclockwise, the movable block can move left and right.
[0011] Preferably, symmetrically distributed limiting rods are installed between the support plates. Symmetrically distributed limiting blocks are installed at the side end of the movable block. Limiting holes are provided on the limiting blocks, and the limiting rods are located in the limiting holes.

[0012] Preferably, a pressure sensor is installed at the end of the hydraulic rod of the third hydraulic device, and a pressure plate is installed at the lower end of the pressure sensor.
[0013] Preferably, the hydraulic rod of the second hydraulic device extends into the positioning groove and is installed with a positioning plate.
