Title:
METHOD FOR MANAGING CONCRETE CASTING AND WIRELESS COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/171647
Kind Code:
A1
Abstract:
Provided is a wireless communication device which can measure a state amount of concrete also during a period from separation of a formwork until achievement of a predetermined strength, and with which defect of the concrete after detachment of the communication device is not caused easily. This wireless communication device 40 comprises a temperature sensor S2 which measures the temperature of concrete C on the inside of sheathing boards 1, 2 in contact and wirelessly transmits a signal S2 of the temperature sensor. This wireless communication device 40 comprises a flange 3 which includes, in an opening 1a formed in the sheathing board 1, a bottom surface 3a flushing with a contact surface 3a of the opening 1a, an insertion portion 5 which protrudes from the flange 3 to the inside of a formwork, has a tapered conical shape, and holds the temperature sensor S2, and a head portion 4 which is exposed from the flange 3 to the outside of the formwork and has a smaller diameter than that of the flange 3, and this wireless communication device 40 is integrated with the concrete C by fixing tools 6 fixing the head portion 4 to the sheathing board 1 in a period until the separation of the formwork and, after the separation of the formwork, is integrated with the concrete C by the hardened and shrunk concrete C holding the insertion portion 5.
