Description

Technical Field

[0001] This utility model belongs to the field of compressive strength testing technology, and more specifically, it relates to a building mortar compressive strength testing device with temperature and humidity compensation function. Background Technology

[0002] Building mortar is a key building material composed of cementitious materials, fine aggregates, water, and admixtures. It is used for masonry construction, plastering, and structural leveling. It develops strength through hydration to ensure the stability and durability of the masonry structure. Therefore, it is necessary to use a compressive strength testing device with temperature and humidity compensation function to eliminate the interference of environmental temperature and humidity fluctuations on the test results, accurately obtain its compressive strength data, and meet the engineering quality acceptance standards.

[0003] Based on the above, the current testing devices lack the function of accurately clamping and adapting to samples of various sizes, making it inconvenient to quickly and stably position samples of different sizes; they also lack the function of accurately controlling temperature and humidity in a closed loop, making it inconvenient to replicate tests under specific environmental conditions. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a building mortar compressive strength testing device with temperature and humidity compensation function. This solves the problems mentioned in the background art, such as the lack of precise clamping and adaptation function for multi-specification samples, making it inconvenient to quickly and stably position samples of different sizes; and the lack of precise closed-loop temperature and humidity control function, making it inconvenient to replicate tests under specific environmental conditions.

[0005] The purpose and effectiveness of this utility model's building mortar compressive strength testing device with temperature and humidity compensation function are achieved through the following specific technical means: A building mortar compressive strength testing device with temperature and humidity compensation function includes a device shell with a rotating door hinged to the front side of the shell; a hydraulic cylinder fixedly mounted on the top of the shell; a plate-shaped water tank fixedly mounted inside the lower part of the shell, with humidifiers fixedly connected to the top corners of the tank; a mounting base with four sets of telescopic rods at the bottom, the bottoms of which are fixed to the lower part of the shell; electric cylinders A fixedly mounted in the middle of the inner walls on both sides of the shell, with alignment plates fixedly mounted on the telescopic ends of cylinders A; and electric cylinders B fixedly mounted on the upper part of the inner walls on both sides of the shell.

[0006] Furthermore, an air inlet is provided above the revolving door, and an exhaust fan driven by a motor is rotatably installed in the air inlet. An electric heating wire is also installed in the air inlet; exhaust ports are provided on both sides of the lower part of the device housing.

[0007] Furthermore, the plate-shaped water tank has an integrally formed water injection platform on the top front side, and a threaded plug is threadedly connected above the water injection platform. An air adjustment hole is opened on the side of the threaded plug through the bottom of the threaded plug.

[0008] Furthermore, a weighing sensor is fixedly installed at the bottom center of the mounting base, and the weighing sensor is attached to the lower inner wall of the device housing.

[0009] Furthermore, a heater is fixedly installed at the center of each of the positive plates.

[0010] Furthermore, a double-sided rack is fixedly provided at the telescopic end of the electric cylinder B.

[0011] Furthermore, two sets of swing rods are rotatably installed on the inner walls of both sides of the device housing, and clamping plates are rotatably installed between the ends of the swing rods in conjunction with the rotating shaft. A counterweight is fixedly installed below the clamping plate. A control gear is fixedly installed outside the rotating shaft of each swing rod, and a double-sided rack meshes with the control gear.

[0012] Compared with the prior art, the present invention has the following beneficial effects: Precise and stable positioning and clamping: Through the electric cylinder B, double-sided rack and pinion, control gear, swing rod and clamping plate, combined with electric cylinder A and alignment plate, bidirectional centering positioning is achieved. The counterweight ensures that the working surface of the clamping plate is always vertical when rotating, which facilitates the clamping plate to fit the building body and effectively avoids the building body from shifting. This provides a precise benchmark for subsequent inspection and processing and improves the reliability of testing.

[0013] High functional integration: It integrates multiple functions such as compressive strength testing, humidification, direct heating and circulating heating, which can meet the performance testing needs of mortar buildings under different temperature and humidity conditions, realize temperature and humidity compensation control, improve the testing process, and simulate the state of the building in different temperature and humidity environments to test the compressive strength effect.

[0014] Easy to operate and maintain: Each function can be started with one button via electric cylinder, hydraulic cylinder, heater and other components; the weighing sensor monitors the pressure data in real time; water can be added by removing the threaded plug from the water filling platform; the overall structure is simple, the operation threshold is low and the maintenance cost is controllable.
