Description

Precast Concrete Total Management System Using Multi-Sensor}

The present invention relates to a precast concrete integrated management system using a multi-sensor, and more particularly, by developing a technology for performing integrated management such as manufacturing, transport, and maintenance after construction, and replacement of precast concrete. While improving the manufacturing quality of concrete, ensuring safety during transportation, continuously monitoring changes in load and occurrence of cracks after construction, and measuring the condition of each construction location of precast concrete after a predetermined period of time, and replacing only damaged parts It relates to a precast concrete integrated management system using a multi-sensor that can greatly reduce costs accordingly.

In general, precast concrete refers to a reinforcing bar 　 concrete 　 member molded and manufactured in a mold at a factory.

Such precast concrete is manufactured in a factory in the form of pieces of a size that can be moved in the construction of building structures such as columns, beams, and floor plates, and it is assembled at the site, thereby reducing the construction time and reducing the weather and temperature of the site. It is not affected by the product, so it can maintain a certain quality, and it is easy to repair and replace as it is assembled and constructed.

Conventional precast concrete structures are manufactured by pouring concrete into a steel mold and performing accelerated curing in a steam curing room with high temperature and humidity, and construction is carried out after being transported to the construction site after construction, and safety is continuously checked after construction. Therefore, if cracks or breakages occur, reconstruction is carried out.

At this time, in the case of precast concrete, if the casting speed and amount of concrete in the mold cannot be kept constant during production, or if the high-temperature and high-humidity environment of the steam curing chamber is not maintained uniformly, internal cracks or bubbles are generated on the surface. There was a problem of occurrence of defects due to peeling.

In addition, if the precast concrete, which is a heavy object, is not fixed incompletely, severe vibration may occur, and if the fixation is released, the vehicle may be overturned, and the angle set when moving in a state mounted on a crane for construction after transportation. If it is inclined more excessively, there is a problem that a worker is injured due to a fall or the crane itself collapses.

And, after the construction of precast concrete as a structure, if an accident such as breakage or collapse occurs, or signs of external damage such as leaks and cracks are found, replacement and reconstruction are performed post-mortem through inspections such as non-destructive inspection or visual inspection. As it is made, there is a problem that economic costs increase, and people are injured due to a collapse accident.

Accordingly, there is a need for a technology for integrated management by continuously monitoring the slope, flow, temperature, and humidity at each production, transportation, construction, maintenance, and repair of a precast concrete structure.

The present invention was conceived in accordance with the above requirements, and an object of the present invention is to develop a technology for performing integrated management such as manufacturing, transport, and maintenance after construction, and replacement of precast concrete to produce precast concrete. The structure improves quality while ensuring safety during transport, continuously monitoring changes in load and occurrence of cracks after construction, and measuring the condition of each construction location of precast concrete after a preset period of time and replacing only damaged parts.
