Description

Autoclaved aerated concrete blocks are mainly composed of quartz sand, calcined calcium sulfate (also known as plaster of Paris), lime, cement, water and aluminum powder, and are heated and pressurized for curing in an autoclave, and are mainly used in building filling wall structures;

[0003] As one of the main materials of autoclaved aerated concrete blocks, the amount of gypsum added will affect the structural performance of autoclaved aerated concrete blocks.

Existing corrosion tests for autoclaved aerated concrete blocks are mostly carried out by simulating a high-humidity environment or immersing the blocks in water. Among them, simulating a high-humidity environment requires using atomizing nozzles to spray water on a closed environment. When the nozzles are damaged, the cover needs to be opened for replacement, which is likely to cause the test to be interrupted or affect the test results, and is inconvenient to use.

[0026] Please refer to the attached Figure 1-7 , and the following technical solutions are provided in this application.

[0027] Embodiment 1, a corrosion resistance detection device for autoclaved aerated concrete blocks. The device includes a simulated corrosion detection box 1, and an upper cover 2 is provided on the upper end of the simulated corrosion detection box 1. A number of placing rods 3 are horizontally and symmetrically arranged inside the upper cover 2. An autoclaved aerated concrete block specimen 4 is horizontally placed on the upper ends of the number of placing rods 3. A water seal groove 21 is provided at the upper end of the simulated corrosion detection box 1. The lower end of the upper cover 2 is inserted into the placing rod 3. When the autoclaved aerated concrete block specimen 4 is placed inside the simulated corrosion detection box 1, in order to avoid the influence of the external environment on the quality of the corrosion structure detection, clean water is poured into the water seal groove 21 to intercept the entry of external air, moisture and temperature into the simulated corrosion detection box 1, so that the autoclaved aerated concrete block specimen 4 undergoes a corrosion test according to the set temperature and humidity.

[0028] A humidity simulation component is provided to inject atomized water vapor into the simulated corrosion detection box 1, so that the autoclaved aerated concrete block specimen 4 is affected by moisture, and the influence of the gypsum dosage in the autoclaved aerated concrete block specimen 4 on the structural performance is studied. The humidity simulation component is movably inserted into the upper end of one side inside the simulated corrosion detection box 1 through an installation component. The humidity simulation component includes a simulated installation disc 6, an access liquid pipe 13 and two atomizing nozzles 10. The installation component includes an installation shaft block 5, an installation screw sleeve 9 and a number of installation steel balls 8. An embedding groove is opened at the upper end of one side inside the simulated corrosion detection box 1. The installation shaft block 5 is horizontally arranged at the center of the embedding groove. An installation groove is opened at the center of one side of the simulated installation disc 6. The simulated installation disc 6 is placed in the embedding groove and movably sleeved on the installation shaft block 5 through the installation groove. When the simulated installation disc 6 is installed with the simulated corrosion detection box 1, first place the simulated installation disc 6 in the embedding groove.

[0029] The mounting shaft block 5 is provided with an annular limiting groove 7 on one side of the mounting groove, and the simulated mounting plate 6 is provided with a fixing groove at the center away from the mounting groove. A threaded rod is provided in the center of the fixing groove, and a mounting screw sleeve 9 is provided on the threaded rod through a threaded sleeve. An annular groove is provided on one side of the fixing groove surrounding the mounting groove, and an abutment ring is provided on one side of the mounting screw sleeve 9, and the abutment ring of the mounting screw sleeve 9 is inserted into the annular groove. A plurality of yielding ball grooves are provided on one side of the annular groove in communication with the mounting groove, and the yielding ball grooves are all movably inserted with mounting steel balls 8, and one side of the mounting steel balls 8 It is placed in the installation groove and inserted into the annular limit groove 7, and when one side of the installation steel ball 8 is inserted into the annular limit groove 7, the inner circumference of the installation screw sleeve 9 abuts against one side of several installation steel balls 8. When the simulated installation disk 6 is sleeved with the installation shaft block 5 through the installation groove, the installation screw sleeve 9 is rotated and pushed forward by the thread. At this time, the abutment ring pushes several installation steel balls 8 to move to one side of the annular limit groove 7 of the installation shaft block 5 and insert them into the annular limit groove 7. At this time, under the limiting effect of the annular limit groove 7, the simulated installation disk 6 cannot be separated from the embedded groove.

[0030] Threaded connection holes are provided on both sides of the simulated installation disk 6, and two atomizing nozzles 10 are respectively connected to the two threaded connection holes through threads on one side. A groove is provided on one side of the simulated installation disk 6 located at the threaded connection hole, and an annular sealing gasket 11 is inserted in the groove. A filter plate 12 is provided between the annular sealing gasket 11 and the atomizing nozzle 10. A liquid access pipe 13 is inserted horizontally through one side of one of the annular sealing gaskets 11 of the simulated corrosion detection box 1 near the simulated installation disk 6, and a liquid access pipe 13 is provided in the liquid access pipe 13 near the side of the simulated installation disk 6. There is an inner cavity, in which a clamping movable joint 14 is inserted, and a sealing rubber sleeve 15 is sleeved on the outer side of the clamping movable joint 14. One side of the sealing rubber sleeve 15 extends out of the inner cavity and abuts against one side of the annular sealing gasket 11, and the diameter of the clamping movable joint 14 close to the simulated mounting disk 6 is smaller than the diameter of the other side. When high-pressure liquid is fed into the clamping movable joint 14, the aperture of the clamping movable joint 14 becomes smaller, and the clamping movable joint 14 pushes the sealing rubber sleeve 15 to be in compression contact with the annular sealing gasket 11, thereby improving the sealing effect of liquid delivery.

[0031] In the present embodiment, after the autoclaved aerated building block sample 4 is placed in the simulated corrosion detection box 1, the upper cover 2 is used to cover the simulated corrosion detection box 1, and then the high-pressure test liquid is sent into the compression joint 14. The test liquid can be clean water or a corrosive liquid. A suitable liquid is selected according to the corrosion test requirements. When the high-pressure liquid passes through the compression joint 14, the compression joint 14 pushes the sealing rubber sleeve 15 to abut against the annular sealing gasket 11 on one side of the simulated mounting plate 6, so that the test liquid sent into the access liquid pipe 13 can enter the atomizing nozzle 10 through the filtration of the filter plate 12, and is atomized and diffused inside the simulated corrosion detection box 1, so that the autoclaved aerated building block sample 4 is in a high humidity space, simulating the corrosion test of the autoclaved aerated building block sample 4 in a high humidity living environment.

[0032] Embodiment 2, on the basis of embodiment 1, is provided with an emergency switching component. When one of the atomizing nozzles 10 is clogged and cannot complete humidity atomization, the atomization and humidification operation can be continued without opening the upper cover 2. The emergency switching component is arranged in the simulated corrosion detection box 1 near the lower end of the simulated installation disk 6. The emergency switching component includes a switching gear 17. The simulated installation disk 6 is placed in the embedded groove and has a plurality of symmetrically opened toggle tooth grooves 16 on the outer peripheral side.

The switching gear 17 is vertically arranged in the gear groove and is meshed with the toggle tooth groove 16 at the lower end of the simulated installation disk 6. A control shaft 18 is horizontally arranged at the center of one side of the switching gear 17. The control shaft 18 passes through the simulated corrosion detection box 1 through horizontal movement of the bearing and is provided with a control The turntable 19, one side of the control turntable 19 is provided with a limiting screw 20 through a threaded connection, and a limiting groove is opened on the outer side of the simulated corrosion detection box 1 close to the control turntable 19, and the limiting screw 20 penetrates one side of the control turntable 19 and is inserted into the limiting groove. When one of the atomizing nozzles 10 is blocked, the limiting screw 20 is first controlled to be away from the limiting groove through the thread, and then the control turntable 19 controls the switching gear 17 to rotate through the control shaft 18. At this time, the switching gear 17 drives the simulated installation disk 6 to rotate, so that the positions of the two atomizing nozzles 10 are interchanged. The blocked atomizing nozzle 10 is replaced, and the unused atomizing nozzle 10 is moved to the position of the access liquid pipe 13 to continue the atomization operation, so as to avoid the damage of the atomizing nozzle 10 during the test, thereby terminating the test and delaying the test research efficiency;

[0033] In addition, there is a diameter difference between the switching gear 17 and the simulated installation disk 6. When the control dial 19 rotates several times, the two atomizing nozzles 10 are just replaced neatly, ensuring that the limiting screw 20 can be inserted into the limiting groove.
