Description

Technical Field

[0001] This utility model relates to the technical field of testing the cold resistance performance of recycled concrete, specifically a device for testing the cold resistance performance of high-strength antifreeze macroporous recycled concrete. Background Technology

[0002] Recycled concrete refers to new concrete made by crushing, washing, and grading waste concrete blocks, mixing them with aggregates in a certain proportion, partially or completely replacing natural aggregates such as sand and gravel (mainly coarse aggregates), and then adding cement, water, etc. Recycled concrete can be classified into several types based on the aggregate composition: all aggregates are recycled; coarse aggregates are recycled and fine aggregates are natural sand; coarse aggregates are natural crushed stone or pebbles and fine aggregates are recycled; recycled aggregates replace part of the coarse or fine aggregates. When testing the cold resistance of recycled concrete, a frost resistance testing device is required; therefore, a high-strength, frost-resistant, large-pore recycled concrete cold resistance testing device is urgently needed.

[0003] The currently used high-strength antifreeze macroporous recycled concrete cold resistance testing device has low testing efficiency, is not convenient for simultaneous testing of multiple concrete blocks, and has poor sealing efficiency when testing the cold resistance of concrete, which can lead to cold air leakage inside the equipment and inaccurate test data. Utility Model Content

[0004] The purpose of this invention is to provide a high-strength antifreeze macroporous recycled concrete cold resistance performance testing device to solve the problems mentioned in the background art, such as the low testing efficiency of the currently used high-strength antifreeze macroporous recycled concrete cold resistance performance testing device, the inconvenience of testing multiple concrete blocks simultaneously, and the poor sealing efficiency of the device when testing the antifreeze performance of concrete, which leads to cold air leakage inside the device and inaccurate test data.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-strength antifreeze large-pore recycled concrete cold resistance performance testing device, comprising an antifreeze testing machine and a heat dissipation mechanism. Both ends of the surface of the antifreeze testing machine are provided with heat dissipation plates, and the heat dissipation mechanism is provided at both ends of the heat dissipation plates. A test chamber is located at the top of the antifreeze testing machine, and sensor insertion holes are provided on both sides of the top of the inner wall of the test chamber. Test grooves are also provided on the inner wall of the test chamber, and air outlets are provided at both ends of the inner wall of the test grooves. A sealing cover is connected to the top of the test chamber, and a sealing strip is provided on the outer edge of the sealing cover. A main body is connected to the outer wall of the antifreeze testing machine, and a control panel is located at the top of the main body.

[0006] Preferably, the heat dissipation mechanism includes mounting strips, a cooling fan, connecting wires, and fixing rods. The mounting strips are all disposed at the upper and lower ends of the surface of the heat dissipation plate. A cooling fan is mounted on the top of the mounting strip, and a connecting wire is connected to the outer wall of the cooling fan. Fixing rods are installed around the outer wall of the cooling fan.

[0007] Preferably, the cooling fan is threadedly connected to the mounting strip via a fixing rod, and both the outer wall of the fixing rod and the inner wall of the mounting strip are threaded.

[0008] Preferably, the test chambers are distributed at equal intervals along the inner wall of the test chamber, and each test chamber has the same size.

[0009] Preferably, the top of the sealing strip is in close contact with the outer edge of the sealing cover, and the size of the sealing strip matches the size of the sealing cover.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This high-strength antifreeze large-pore recycled concrete cold resistance performance testing device, through the setting of test chambers and test tanks, makes it convenient to test the cold resistance performance of multiple pieces of recycled concrete. Multiple sets of test tanks in the test chamber can be used to place multiple pieces of recycled concrete into different test tanks at the same time for testing, thereby improving the testing efficiency of recycled concrete and saving the testing time.

[0012] 2. This high-strength antifreeze large-pore recycled concrete cold resistance performance testing device, through the setting of a heat dissipation mechanism and sealing strip, facilitates the operation of the equipment. The heat generated inside the antifreeze test machine during operation can be assisted by the cooling fan in the heat dissipation mechanism, thereby ensuring that the test machine operates at a good temperature. In addition, the sealing strip on the outside of the sealing cover can provide a sealing effect at the gap between the sealing cover and the test chamber during the antifreeze test of recycled concrete, preventing the leakage of cold air from the test chamber.

[0018] Please see Figure 1-3 This utility model provides a technical solution: a high-strength, frost-resistant, large-pore recycled concrete cold-resistance performance testing device, including a frost-resistant testing machine 1 and a heat dissipation mechanism 3. Heat dissipation plates 2 are provided at both ends of the surface of the frost-resistant testing machine 1. The heat dissipation mechanism 3 is provided at both ends of the surface of the heat dissipation plates 2. The heat dissipation mechanism 3 includes mounting strips 301, a cooling fan 302, connecting wires 303, and fixing rods 304. The mounting strips 301 are provided at the upper and lower ends of the surface of the heat dissipation plate 2. A cooling fan 302 is mounted on the top of the mounting strips 301, and the connecting wires 303 are connected to the outer wall of the cooling fan 302. Fixing rods 304 are installed around the outer wall of the cooling fan 302. The hot air fan 302 is threadedly connected to the mounting strip 301 via the fixing rod 304, and both the outer wall of the fixing rod 304 and the inner wall of the mounting strip 301 are threaded. With the heat dissipation mechanism 3 and the sealing strip 9, the heat generated inside the antifreeze testing machine 1 during operation can be assisted by the heat dissipation fan 302 in the heat dissipation mechanism 3, thereby ensuring that the testing machine operates at a good temperature. In addition, the sealing strip 9 on the outside of the sealing cover 8 can provide a sealing effect at the gap between the sealing cover 8 and the test chamber 4 when conducting antifreeze tests on recycled concrete, preventing the leakage of cold air in the test chamber 4.

[0019] The freeze-thaw testing machine 1 has a test chamber 4 at its top, and sensor insertion holes 5 are provided on both sides of the top of the inner wall of the test chamber 4. Test grooves 6 are provided on the inner wall of the test chamber 4. The test grooves 6 are evenly distributed on the inner wall of the test chamber 4, and each test groove 6 is the same size. Air outlets 7 are provided at both ends of the inner wall of the test groove 6. The top of the test chamber 4 is connected to a sealing cover 8, and a sealing strip 9 is provided on the outer edge of the sealing cover 8. The top of the sealing strip 9 is in close contact with the outer edge of the sealing cover 8, and the size of the sealing strip 9 matches the size of the sealing cover 8. The outer wall of the freeze-thaw testing machine 1 is connected to a main body 10, and a control panel 11 is provided on the top of the main body 10. With the test chamber 4 and test grooves 6, when testing the freeze-thaw performance of multiple pieces of recycled concrete, multiple pieces of recycled concrete can be placed in different test grooves 6 in the test chamber 4 for testing at the same time, thereby improving the testing efficiency of recycled concrete and saving the testing time.

[0020] Working Principle: When testing the freeze-thaw resistance of recycled concrete, multiple pieces of recycled concrete are first placed in test tanks 6 within the test chamber 4. The temperature sensor and tracking sensor are inserted into the sensor sockets 5 at the top of the test chamber 4. The sensors monitor the temperature inside the test chamber 4. Then, the sealing cover 8 is placed on top of the test chamber 4. The temperature inside the test chamber 4 is controlled via the control panel 11. The freeze-thaw testing machine 1 is connected to an outdoor unit. Similar to an air conditioner, the condenser inside the freeze-thaw testing machine 1 and the heat exchanger of the outdoor unit generate cold air, which is then circulated through the air outlet 7 to freeze the recycled concrete in the test tanks 6. In addition, multiple sets of test tanks 6 opened in the test chamber 4 can be used to simultaneously place multiple pieces of recycled concrete into different test tanks 6 for testing, thereby improving the testing efficiency of recycled concrete and saving the testing time. At the same time, the sealing strip 9 on the outside of the sealing cover 8 can provide a sealing effect at the gap between the sealing cover 8 and the test chamber 4 during the freeze-thaw test of the recycled concrete, preventing the leakage of cold air in the test chamber 4. After the freezing is completed, the recycled concrete can be taken out and its hardness and other parameters can be tested. This completes the operation process of the high-strength freeze-thaw resistance large-pore recycled concrete cold resistance performance testing device.
