[0002] The temperature and humidity inside concrete are indicators of concern in concrete research. At present, in order to study the temperature and humidity changes inside concrete under different test conditions, it is often necessary to cure the concrete specimen to a specified age after it is formed, and then artificially create a hole for burying a thermometer and hygrometer by drilling. However, there are some problems with the drilling method: on the one hand, drilling holes in early-age concrete is often prone to damage to the entire specimen due to the concrete specimen strength not meeting the standard; on the other hand, when drilling holes in concrete after curing, the drill bit will inevitably slip and tilt during the drilling process, causing the hole to deviate from the preset position, affecting the subsequent monitoring of the temperature and humidity inside the concrete. At the same time, the random distribution of hard aggregates increases the difficulty of drilling and also affects the depth of drilling, resulting in low drilling quality. Utility Model Content

The inner diameter of the inner ring 6 of the locking device is the same as the outer diameter of the embedded pipe 2.
[0031] A concrete mold for burying a thermometer and hygrometer comprises a bottom plate 11, a groove on one side of the bottom plate 11 is connected to a first baffle 1, a second baffle 9 is arranged on the left side of the bottom plate 11, a third baffle 10 is arranged on the right side of the bottom plate 11, grooves are arranged on the front and rear sides of the bottom plate 11, the second baffle 9 and the third baffle 10, the front grooves of the bottom plate 11, the second baffle 9 and the third baffle 10 are used to fix the first baffle 1, and the rear grooves of the bottom plate 11, the second baffle 9 and the third baffle 10 are used to fix the fourth baffle 12.
[0032] A second fixing device 8 is provided on one side of the second baffle plate 9, and a first fixing device 7 is provided on one side of the third baffle plate 10. Both sides of the outer ring 3 of the locking device are fixedly connected to the inner walls of the first fixing device 7 and the second fixing device 8 respectively. The inner sides of the first fixing device 7 and the second fixing device 8 are provided with fixing ring grooves for fixing the outer ring 3 of the locking device.
[0033] The outer ring 3 of the locking device is respectively clamped with the threaded inner walls of the three groups of tightenable nuts 4. The outer ring 3 of the locking device is connected to the three groups of tightenable nuts 4. The angles between the three groups of tightenable nuts 4 are 120°. Each group of tightenable nuts 4 is provided with a fixing spring 5. The bottom end of each group of tightenable nuts 4 is connected to the inner ring 6 of the locking device. By tightening the three groups of tightenable nuts 4, the center of the inner ring 6 of the locking device is aligned with the center of the hole of the first baffle 1, and then the embedded pipe 2 is locked. The inner ring 6 of the locking device of the adjustable pipe diameter locking device is aligned with the center of the first baffle 1;
[0034] Brief introduction to the usage of the parts corresponding to each mark:
[0035] The baffle 1 is a detachable baffle on one side of the concrete mold. A hole is opened in the center of the baffle according to the diameter of the embedded pipe 2, and embedded pipes 2 of different diameters can pass through.
[0036] Pre-buried pipes 2. By pre-buried pipes during the concrete forming process, the later drilling steps are avoided.
[0037] The plastic rod 201 of the corresponding pipe diameter is inserted into the embedded pipe 2 to prevent cement slurry from entering the embedded pipe 2 and causing blockage during concrete pouring. At the same time, the embedded pipe is supported to prevent it from being squeezed and deformed. The plastic rod 201 is pulled out after the concrete is finally set.
[0038] The adjustable pipe diameter locking device comprises a locking device outer ring 3 with a steel outer ring, three sets of tightening nuts 4, and a locking device inner ring 6. After the embedded pipe 2 passes through the hole of the first baffle 1 and the central hole of the locking device inner ring 6 in sequence, the three sets of tightening nuts 4 are screwed to fix the embedded pipe 2.
[0039] Working principle (how to use):
[0040] In the first step, the first baffle 1 of the mold (the size required for the test) is inserted into the grooves in the second baffle 9, the third baffle 10 and the bottom plate 11. The rear grooves of the second baffle 9, the third baffle 10 and the bottom plate 11 are fixedly connected to the fourth baffle 12 to fix the mold.
[0041] In the second step, the outer ring 3 of the locking device is clamped into the first fixing device 7 and the second fixing device 8 on the second baffle plate 9 and the third baffle plate 10 .
[0042] The third step is to select the embedded pipe 2 of the required diameter for this test, pass it through the first baffle 1 of the front baffle of the mold, the inner ring 6 of the locking device in the center of the spring locking device, adjust the length of the embedded pipe 2 in the concrete mold, and finally insert the plastic rod 201 into the embedded pipe 2.
[0043] The fourth step is to keep the embedded pipe 2 always in the exact center position of the inner ring 6 of the locking device by adjusting the three sets of tightening nuts 4 in the spring locking device to prevent displacement.
[0044] Step 5. After assembly is complete, concrete can be placed in, followed by tamping, compacting and smoothing.
[0045] Step 6: After the concrete is finally set, pull out the plastic rod 201.
[0046] The concrete mold for burying the thermometer and hygrometer in this patent can not only be used for burying the thermometer and hygrometer, but also can be used to form concrete test pieces of pre-buried pipes. An adjustable pipe diameter locking device is used on the mold to ensure that pre-buried pipes 2 of different pipe diameters can be fixed.
