Description

Technical Field

[0001] This utility model relates to the field of concrete testing devices, specifically a multi-field coupled integrated test platform for the study of the durability of multi-size concrete. Background Technology

[0002] Concrete is a general term for engineering composite materials in which aggregates are bound together by cementing materials. Generally, the term "concrete" refers to cement concrete, which is made by mixing cement and active mineral admixtures as cementing materials, sand and gravel as aggregates, and adding necessary additives with water in a specific ratio. It is widely used in civil engineering. The quality of concrete is generally evaluated by testing its mixture properties, physical and mechanical properties, and durability. Among these, the durability of concrete directly determines its lifespan.

[0003] Currently, concrete durability testing is generally conducted indoors on small-sized test blocks. This is mainly because the instruments and equipment used for testing concrete durability are insufficient for testing large-sized components. Furthermore, the environmental conditions for large-sized components in actual engineering projects are far more complex than those in indoor tests, and the test results for large-sized components may differ from those for small-sized test blocks. Therefore, durability testing for large-sized components is more necessary and more closely reflects real-world conditions. Among these, a concrete durability testing and measuring device, with application number "CN201821617155.X", describes such a device by setting... The device consists of a pressure sensor, a placement tank, a hydraulic cylinder, and a pressure column. The hydraulic cylinder pushes the pressure column to press down on the concrete block, and the pressure sensor transmits the pressure on the concrete to a microcontroller, avoiding time-consuming and laborious manual testing and improving the accuracy of the test. However, this experimental device can only conduct durability tests on the test blocks in a normal temperature environment. Concrete durability is affected by a variety of factors such as ambient temperature, humidity, and acid / alkaline environment, and the environment in which the concrete exists may combine one or more of the above factors. The above device cannot meet the requirement of conducting durability tests on large-sized concrete test blocks under multi-field coupled environments such as temperature, humidity, and acid / alkaline environment as proposed above.

[0004] Therefore, designing an experimental platform that can couple concrete tests in multiple scenarios can better detect concrete. Utility Model Content

[0005] The purpose of this invention is to provide a multi-field coupled comprehensive test platform for the durability study of multi-size concrete, in order to solve the problem that the experimental device proposed in the background technology cannot meet the requirements of conducting experiments on large and small concrete specimens of different sizes under multi-field coupled environments such as temperature, humidity, acid and alkali. Therefore, designing an experimental platform that can couple concrete tests in multiple scenarios can better detect concrete.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A multi-field coupled integrated test platform for durability research of multi-size concrete includes a test chamber, a spray assembly, and a heating assembly;

[0008] The test chamber is equipped with a placement rack, and the test chamber is fixedly installed with fixing plates on both sides of the placement rack.

[0009] The spray assembly includes a hanger installed inside the test chamber. A support rod is installed at the bottom of the hanger. A fixing buckle is installed on the surface of the support rod. A water supply pipe is installed inside the fixing buckle. Several nozzles are installed on the surface of the water supply pipe. The nozzles are correspondingly arranged on the top of the placement frame. Two liquid storage tanks are placed outside the test chamber. A booster pump is installed on one side of the bottom of each of the two liquid storage tanks. A three-way valve is installed at the water outlet of each of the two booster pumps. The water outlet of the three-way valve is fixedly connected to one end of the water supply pipe.

[0010] The heating assembly includes steam generators mounted on both sides of the surface of the fixed plate. A water tank is provided outside the test chamber. A water pump is installed on one side of the bottom of the water tank. The outlet of the water pump is connected to a water supply pipe. One end of the water supply pipe is connected to the steam generator.

[0011] Furthermore, mounting holes are provided on both sides of the test chamber, and mounting frames are installed inside the mounting holes. Ventilation fans are installed inside the mounting frames, and an adjustment baffle is hinged to the inner wall of one end of the mounting frame.

[0012] Furthermore, a temperature sensor is fixedly installed in the center of the surface of the fixing plate, and a humidity sensor is installed on one side of the surface of the fixing plate.

[0013] Furthermore, the test chamber is equipped with ultraviolet lamps on its ceiling.

[0014] Furthermore, a collection pool and a drainage ditch are excavated inside the test chamber. One end of the drainage ditch extends to the bottom of the placement rack, and the other end of the drainage ditch is connected to the collection pool. Both the collection pool and the drainage ditch are covered with protective covers.

[0015] Furthermore, the test chamber is equipped with a control panel, and the booster pump, three-way valve, water pump, ventilation fan, temperature sensor, humidity sensor, and ultraviolet lamp are all electrically connected to the control panel, which is electrically connected to an external power supply.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] (1) A hanger is installed inside the test chamber. A support rod is installed at the bottom of the hanger. A water supply pipe is installed on the support rod through a fixing buckle on the surface. The nozzle installed at the bottom of the water supply pipe corresponds to the placement frame. When the booster pump works, the liquid inside the storage tank is sprayed onto the concrete test block on the surface of the placement frame through the nozzle. Different corrosive liquids are placed inside the storage tank. A three-way valve is installed at the water outlet of the booster pump. The three-way valve can control the spraying of different liquids, which is convenient for testing the corrosion resistance of concrete.

[0018] (2) With the heating components provided, steam generators are installed on both sides of the fixed plate surface. When the water pump works, the water in the water tank is transported to the steam generator through the water delivery pipe. The hot steam generated by the steam generator facilitates the increase of the temperature inside the test chamber. With the spray nozzle spraying liquid agent, the concrete can be tested in multi-field coupled comprehensive test. Attached Figure Description

The nozzle 45 installed at the bottom of the water supply pipe 44 corresponds to the placement rack 2. When the booster pump 47 is working, the liquid inside the storage tank 46 is sprayed onto the concrete test block on the surface of the placement rack 2 through the nozzle 45. Different corrosive liquids are placed inside the storage tank 46. A three-way valve 48 is installed at the water outlet of the booster pump 47.
