Description

  At the construction site, we conducted a lightning strike simulation test on the metal used for the building before placing concrete, and inspected whether or not the lightning surge current flows safely to the foundation pile ground. The present invention relates to a method (construction method) for monitoring spark discharge, concrete destruction, and corrosion from metals.

  Currently, building engineers and IT engineers around the world will destroy circuit boards in buildings, electrical outlets such as TVs and PCs, etc., due to lightning noise current generated when lightning strikes buildings. We recognize that the importance of risk management is increasing. And while various lightning countermeasures are being promoted, the present inventor also made the entire structure of the building corresponding to the lightning noise current, the internal structure of the floor, the equipotential ground connection method and the like between 1999 and 2005. Various lightning countermeasure technologies such as lightning arresters have been proposed (see Patent Documents 1 to 3). The inventor of the present invention pays attention to the fact that electromagnetic wave countermeasures and static electricity countermeasures for buildings and electrical equipment have not been merged, and noise sensors are electrically connected to the building's reinforcing bars and steel frames to generate noise currents from lightning. Have proposed a monitoring system.

  However, the conventional monitoring system has the following drawbacks. For example, the altitude of the land where agricultural vinyl houses, wooden general houses, monitoring towers for water and sewerage systems, factories, hospitals, buildings, etc. are constructed, that is, the sea level where the buildings are constructed was not considered. That is, the difference in the discharge distance between the coast, the flatland, the highland, the mountainous area, and the thundercloud was not considered.

Therefore, in the lightning noise monitoring system including the conventional lightning rod, equipotential bonding earth, and lightning arrester, the following points need to be further improved.
(1) A method of connecting the steel frame / rebar structure of a building subjected to direct lightning strikes to the earth ground.
(2) The relationship between the current flowing into all conductive cables including electric wires and communication cables that have received induced lightning, and the ground.
(3) Means for preventing excessive current generated from direct lightning strikes, noise current such as lightning, and lightning current to a place close to the building from flowing into the grounding means of the building.

  An existing building that is not equipotential bonding earth structure, or a construction altitude (above sea level), that is, a building designed without considering the distance between the thundercloud and the building, and the ground layer and depth to be grounded, etc. Even if it is applied to a potential ground structure, safety cannot be confirmed without actually conducting a discharge test. However, in the past, methods and equipment that simulate such a lightning strike in advance at a construction site Did not exist. In addition, the method of construction while verifying whether or not the reinforcing bars and metals in the wooden building and the foundation concrete, the metal parts of the reinforcing bars and steel frames in the building and the foundation part grounded to the ground are reliably electrically connected, There was no system to monitor the destruction of rebars and concrete caused by lightning strikes and to report this. In particular, when lightning strikes directly on buildings, including wooden buildings, plastic houses, railways, highways, harbor facilities, plant facilities, and when electrical wires connected to breakers are disconnected, electrical leakage has occurred in equipotential metals. Since there is no monitoring system that knows, it is impossible to determine where the leakage is from.

JP 2001-169460 A JP 2001-249131 A Japanese Patent No. 4048314

  Therefore, the present inventor has developed a technology in which a computer in a machine does not malfunction even if it is affected by the discharge noise of a fuel ignition plug in a traffic machine having a metal casing such as a railway vehicle, an automobile, an aircraft, a ship, etc. In the case of applying to the building the structure of the aircraft that will fly safely in the thundercloud that discharges from the time it takes off until it reaches the stable flight altitude, and the action of excess current discharging from the tip of the wing, We focused on the fact that it would be possible to protect against lightning currents even in buildings that were set up in the sky.

  That is, the most important consideration for lightning strikes is the distance from the thundercloud K to the ground surface G. It is common practice to install lightning rods and arresters in high-rise buildings of several tens of meters or more. For example, a one-story building built on 50m above sea level is located on the top of a 50m building built on flat ground. Despite its height, lightning protection measures were inadequate. Since lightning never falls only on a lightning rod, it is assumed that there will be a lightning strike on all conductive materials used in the building, and how to ground noise currents such as induced lightning and static electricity. It is necessary to consider. Furthermore, if you install solar power on the site, the roof of a wooden building, the rooftop, side, glass window, etc. of a building, and the support for the power generation panel is made of metal, If the photovoltaic panel, gantry, and antenna are not equipotentially connected, it will act as a lightning rod, increasing the possibility of lightning strikes, and manufacturers around the world are not considering the need for an equipotential grounded gantry. However, it is not considered to connect a lightning arrester as a noise current avoidance circuit to the panel and the storage battery.

However, the current building specifications do not have a special method for determining which part of the building has been struck by light, and the noise current induced in all the conductive cables is equivalent to the equipotential ground terminal in the outlet and the earth ground. There is no outlet box or relay box that can be circulated. As a general grounding method for buildings, multiple earth plates and earthing rods are embedded in the strata with a depth of several meters, but even if these are connected to an equipotential using an earth cable, it is excessive. Current needs to flow deeper. The reason is that the strata of several meters from the ground is wet, and before the excess current flows into the deep strata, it flows in all directions in the horizontal direction, and the wet ground is the same as the motherboard on which electronic components are mounted. This is because it has a theoretical structure.
On the other hand, in other countries (especially in the EU), it seems that the construction method of passing lightning current through gas pipes and water pipes has permeated. In Japan, however, the pipes themselves have been broken due to the Great Hanshin Earthquake. In Asia, where earthquakes occur frequently, there are no engineers who connect the earth to gas or water pipes.

  In addition, there is no equipment to be tested assuming a lightning strike on a reinforcing bar before placing ready-mixed concrete on a formwork such as a building foundation. This is because lightning is designed with the general stereotype of falling on the top of the building. Therefore, the current situation is that we have not been able to recognize personal accidents due to lightning strikes during construction, effects on electrical equipment, and weakening of buildings due to the destruction of foundation concrete.

  In fact, steel frames under construction, rebars embedded in foundation concrete or floor concrete may be damaged or melted by lightning strikes (Otwa 5th Lightning Photo Contest Silver Award Photo “Skeleton Building” 2007 June 14th (see Bangkok Rama III Street), such a wall is difficult to identify after building construction, and it is also difficult to identify the location of electrical leakage. For this reason, using a noise discharge tester that can generate surge currents such as lightning, static electricity, and electromagnetic waves in a simulated manner, the metal parts (reinforcement, steel frame, frame, earthquake-resistant fittings, gas pipe, It is important to inspect the connection status of water pipes and hanging bolts, etc., and it is important not to neglect the safety by conducting a simulated lightning discharge on site during building maintenance after construction.

  In addition, in greenhouses and farmhouses and one-story houses including wooden structures, conventional grounding cables of Class A, Class B, Class C and Class D and reinforcing bars and steel frames used in buildings are used. And it is not electrically connected to the reinforcing bar used for the foundation and the metal used for the grounding rod / grounding board or the foundation pile.

  Normally, thunderclouds K are located several thousand meters above sea level, but the high-rise building T2 is closer to the discharge distance in units of several hundred meters than the flat building T1 (see FIG. 1). For example, when a 10-story building is built at a high altitude of 800 m above sea level, lightning strikes S are not always on the top floor. In addition, the aircraft P's enclosure receives the combined current and voltage of static electricity generated by frictional resistance when the aircraft P enters the thundercloud K and the charge of the thundercloud K, but the electronic devices in the aircraft are protected and stored in the wings. Does not ignite even fuel. In addition, since engine noise is attenuated by resistance, the discharge theory from this wing is applied to the foundation pile grounding board.

  As can be seen from the Kirchhoff circuit and the bridge circuit shown in FIGS. 2 to 4, both ends of two parallel wires ac and bd are connected in parallel, and both ends of the wire e are connected to ac and b. As can be seen from the fact that when a voltage is applied to both ends of a and b when the wire is connected to the middle point of two wires connected in parallel with -d, no current flows through the wire of e, as shown in FIG. It is only when a lightning strike S strikes a lightning rod that the lightning current flows evenly through 1b, 1c and 1d. When a lightning strike S occurs in a place other than the lightning rod (for example, beam 2 etc.), this problem can be solved by connecting the ground plate 3 to the reinforcing bar of the foundation pile 23 of the building. In addition, if the foundation pile 23 is formed in a screw shape, driving into the ground is also simplified.

  As a verification, it can be seen from Kirchhoff's law that if the resistance is the column 1a, column 1b, column 1c, and column 1d on the wire equivalent circuit shown in FIG.

  That is, as shown in FIGS. 5 to 6, when a new building is constructed, in the free access F of the floor 9, if ground is taken from the four beam bars 2, the ground in the floor 9 becomes equipotential and zero. Close to resistance. Between each column 1a, column 1b, column 1c, and column 1d, a horizontal beam 2 extending in the horizontal direction is provided, and a conductive wire (ground wire) is connected to a substantially midpoint of the beam 2 via an earth box (not shown). ) Is connected to the earth side of the lightning arrester. Since the beam 2 is structurally higher in electrical resistance than the bar 1 (the conductor is thin), even if induced lightning strikes the building, a surge current or static electricity exceeding a predetermined value is generated in the beam 2 There is no. A grounding plate 23 or 3 a is connected in parallel from the lightning rod H to the ground via a lightning conductor 15. This grounding plate 3a is of a so-called class A grounding construction (grounding construction type / first kind grounding construction until June 2003; high-voltage and high-voltage grounding construction). Seed grounding work; extra high voltage or medieval point or one terminal of a transformer that couples high and low piezoelectric roads, Class C grounding work (Type 3 grounding work; metal of equipment when insulation of low voltage equipment deteriorates) Grounding work to reduce the contact voltage applied to the outer casing), Class D grounding work (Class 4 grounding work; Machine / equipment iron base / lightning arrester, emitter, insulation resistance of metal parts of protective devices for high voltage cables) In addition to being electrically connected to each grounding plate 3a, 3c, 3d (within 100Ω grounding), the equivalent circuit is connected to the pillar 1a, pillar 1b, pillar 1c and pillar 1d of the building buried in the ground. It is formed.

  Therefore, in any building, it is preferable to perform equipotential grounding using the metal support 1 and the beam 2 which are the framework. However, the domestic grounding standards before June 2003 were different from Class A 10Ω, Class B / C Earth 10Ω, Class D 100Ω, so these were re-equivalent in renovation of existing buildings and seismic reinforcement work. Must be grounded.

  As shown in FIG. 7, each steel pillar 1 a, pillar 1 b, pillar 1 c, and pillar 1 d may be connected to a foundation pile ground 23. The ground pile 3 (3a, 3b, 3c, 3d) of the existing building is buried in the ground of 3m to 5m, and the foundation pile ground 23 and the existing ground plate 3 are connected to the same potential. For example, even if there is a lightning strike on a tree or the like in the vicinity of the building, the surge current does not flow back to the ground cable connected to the inside of the building. In the unlikely event of backflow, protect with a lightning arrester.

  For example, as shown in FIG. 7 and FIG. 8, the foundation pile ground 23 is backfilled with concrete 25 a in a state where a plurality of blades 23 a extending in the radial direction are attached to the lower end portion thereof and spread in the buried hole 25. As a result, the surface area of the earth body is increased, the contact area with the ground is increased, and a large current during a direct lightning strike can also flow.

  Here, the surge current discharge method according to the present invention is a method of artificially discharging a high voltage surge current such as lightning, static electricity, electromagnetic waves, etc. from a ground terminal of a lightning arrester installed in a building. A noise sensor 30 configured to be perceptible by visual or auditory sense is provided, and a low / high voltage current generator 32 is provided.

  As a specific surge current discharge method, for example, as shown in FIG. 9, a noise avoidance box 10 provided with a low / high current generator 32 and a leakage monitoring panel 33 in a building is equipped. The noise avoidance box 10 has a power source (solar power generation / wind power generation / vibration power generation) 31 and a power cable using natural energy connected in parallel with the commercial power source 12 to enable transmission in any situation such as a disaster. 12a, the breaker 14 and the storage battery 13 are housed in a power distribution device storage space 13B, and a mobile phone / wireless transmission / reception device 26, an electronic device storage space 13A in which a PC HUB 27, etc. are stored are made of a metal shield plate 15.

Further, the power cable 12a is connected to the plus and minus poles of a coiled noise filter 7 or 21 configured by connecting the coil 5 and the resistor 6 in parallel or connecting the coil 5 and the capacitor 6 in parallel via the breaker 14. The line terminal of the discharge bounce wave avoidance circuit is connected in parallel, and the noise current discharged to the negative pole of the lightning arrester 4 flows to the frame (FG), and arc discharge and glow discharge generated when the device is switched off The coil type noise filter 7 or 21 is used to prevent the voltage and high frequency noise exceeding static electricity with the gap type lightning arrester 4. Gap-type lightning arresters 4 are also interposed between the power supply side and the outlet side of the filter 21, and all the sensors installed in the site (optical communication, fire alarm, monitoring camera, security, power generation system, cooler system, water and sewage equipment) Connect the power and power boxes in parallel.

  In the distribution device storage space 13B, a plurality of lightning arresters 4 with a low / high frequency noise filter 21 and a ground cable 11 are connected to a power cable 12a drawn from a commercial power supply 12 via a ferrite core 19, A coiled noise filter 21 is provided between the power supply 12 and the power outlet 18. For example, a lightning rod or breaker 14 close to the top floor of the building has an IEC standard for 50 KA (kiloampere) 10/350 μsec for 40 KA (kiloampere) or 8/20 μssec for 40 KA (kiloampere) in series / parallel connection. A 20KA (kiloampere) gap type arrester 4 for 2/50 μsec and a gigahertz band (GHz) coil type high frequency noise filter 21 are connected in series and in parallel.

  The optical communication cable 28 inserted from the outside into the noise avoidance box 10 is connected to the optical communication cable HUB 27 </ b> A via the discharge gap type lightning arrester 4. A cable branched from the optical communication cable HUB 27A is connected to the PC HUB 27B in the electronic device storage space 13A. The discharge gap type lightning arrester 4 and the ferrite core 19 are also attached to this communication cable. A coiled noise filter 5 in which a resistor 6 is connected in parallel is provided between the PC HUB 27B and the ground cable 11. The wristband 22 is connected to the primary side of the discharge terminal, and the ground cable 11 is connected to the secondary side of the discharge terminal to protect electronic devices such as PCs from static electricity generated by workers during the installation work. Further, a noise sensor 30 with a counter is attached to the ground cable 11 to count the number of lightning strikes and noise occurrences.

  That is, the four seismic reinforcement brackets 1A to the existing building and the lightning rod H on the roof are connected to the same potential, and all the conventional ground cables are connected to the beam 2 of the reinforcement bracket 1A at the same potential. Here, as the power cable 12 in the building, it is preferable to use a shielded electric wire cable that does not pick up noise. In the monitoring system, a current sensor 34 for electric leakage can be provided, and signal current flowing through the current sensor 34 can be collected and stored.

It is possible to divide and store the cables in the cable storage pipe 40c, and to remove static electricity generated by the operator when all the cables are connected by the wristband 22 connected to the ground.

Specifically, the positive pole of the low and high voltage current generator is connected to the reinforcing bar of the building foundation 8, each floor 9, pillar 1, beam, girder 2, etc. before placing the ready-mixed concrete, and the lightning test current is It is possible to check for abnormalities such as rebar dissolution. Further, there is a secondary effect that the pests 35 and their eggs 35a in the ground can be controlled by periodically discharging and supplying a discharge current. Further, by periodically passing a lightning experiment current, rust generated in the reinforcing bars inside the concrete can be prevented, and the oxidation can also be prevented by mixing the rocks into the concrete 25a of the foundation ground pile 23.

  In the monitoring system, it is preferable to collect and store the signal current flowing through the current sensor. In addition to solar power generation and wind power generation, noise generation (thunder, static electricity, electromagnetic waves flowing in the current sensor), cooler outdoor units and wind generators in indoor units, and sound generation by collecting sound such as noise it can.

  Further, as shown in FIG. 14, the metal part of the photovoltaic power generation panel base 41 and the like installed on the rooftop of the building T1 is not normally equipotentially grounded, so there is a surge current escape path when a lightning strike occurs. Absent. Therefore, reinforcing bars in the foundation of wooden houses, metal fittings that support solar power generation attached to earthquake-resistant reinforcement brackets or roofs, earthquake-resistant reinforcement metals on the four sides of buildings, lightning rods H on the roof, and metal of the power generation system, etc. It is better to connect the potentials and equipotentially connect all the conventional ground cables to the reinforcing metal beam. If the power cable in the building is a shielded electric cable, it is not necessary to pick up noise. Moreover, a wind power / sunlight / vibration / sound power generation system can be obtained by flowing the noise current through the ground pile 23 embedded in the ground and charging the storage battery with the noise current.

  In addition, this invention is not limited to the said Example, A various application deformation | transformation is possible. Computers are listed as an example of electrical devices protected by lightning arresters, but the protected devices are (conversion) hubs, distribution boards, optical fiber cables and other related devices such as optical fiber cables and related devices, or unmanned water and sewage systems. It may be a facility, a complex facility, a factory facility, etc., a surveillance camera system, a disaster prevention system / security system monitoring room, and each floor or server monitoring system floor circuit. That is, a lightning arrester can be connected to the tension member of the optical fiber and the outlet portion of the commercial power supply, and each lightning arrester can be grounded to a nearby beam to prevent lightning. In addition, it is preferable to use a shield line that does not pick up noise as the lead-in line (current line / voltage line) in the above embodiment.

In addition, even in special buildings such as wireless base stations, all communication and network radio boxes inside the building are equipped with a noise countermeasure outlet box, a power breaker for the distribution board, and a filter type lightning arrester to ensure thorough noise countermeasures. It is considered that this can be achieved.
Therefore, in the plant, power generation system building, or existing building and new building, aeronautical mechanics and ship. Equipotential theoretical configuration of automobiles and other countermeasures to prevent reflected waves from engine plugs as a countermeasure against noise, and a ground pile with a deep foundation pile in the ground to release noise currents, and noise (lightning, static electricity, electromagnetic waves, magnetic fields) ) Electricity is stored in the battery and the storage system is a new system as an eco building. Noise countermeasures cause the temperature to rise with noise current from all buildings by passing an excess current through the wires like a cooking heater. It is important to have a system that prevents heat from being generated by electronic device manufacturers that flow more in the electronic board than the board current that flows in the laboratory.
In the future, charging boxes for electric vehicles, charging stands, etc. will be built in parking lots for general households, on-site and building parking lots, etc. Is a system that receives noise from a PC, mobile phone, etc. and visually recognizes it, and a noise power generation system connected in parallel with solar power generation, wind power generation, or vibration power generation is stored in a storage battery and measures against noise are indispensable. .
