Description

  The present invention relates to a connection structure for grounding a reinforcing bar used in reinforced concrete or the like.

  In general, lightning rod equipment for a reinforced concrete building is usually installed on the roof of a building. Since the lightning rod equipment needs to be grounded to the ground, the main bars (rebars) arranged inside the pillars on each floor of the building are connected electrically, and the lightning rod of the lightning rod equipment is connected to the grounding pole. It is supposed to be. As a structure for electrically connecting the reinforcing bars, for example, there is a structure shown in Patent Document 1. The connection structure of Patent Document 1 is connected to a column main reinforcement arranged in a column on the lower floor, is grounded in the ground, and at least a part of the first is exposed on the surface of the floor formed on the column. The conductive member is electrically connected to the column main reinforcement disposed on the column of the upper floor and is connected to the lightning rod and at least partly electrically connected to the second conductive member exposed at the lower end surface of the column. It has a structure. And in this patent document 1, the electroconductive member for electrically connecting is comprised from the metal plate, the metal rod, etc., and these are connected with the column main reinforcement by welding. However, when connected by welding in this way, thermal stress is generated during welding, the strength of the column main bars is reduced, and the structural strength of the building may be reduced.

  Moreover, in order to electrically connect each reinforcing bar without using welding, there is a connection fitting as described in Patent Document 2. The connection fitting of Patent Document 2 has a structure in which a reinforcing bar is sandwiched between two substantially circular sandwiching members that are in close contact with the outer peripheral surface of a substantially cylindrical reinforcing bar, and the clamping member is tightened with a bolt. And according to patent document 2, since it can connect without using welding like patent document 1, it comes to be able to connect easily in the construction site of a building, without reducing the intensity | strength of a column main reinforcement.

  However, in general, column main bars used in reinforced concrete structures and the like are provided with protrusions such as ribs and nodes on the surface in order to increase strength, and the sizes (diameters) of the column main bars are various. For this reason, when a connection metal fitting like patent document 2 is used, two pinching members may be unable to adhere completely by the projection part of a pillar main reinforcement. Further, since the protrusions and sizes of the column main bars are various, it is necessary to manufacture a connection metal suitable for each reinforcing bar, which takes time and cost.

  Therefore, an object of the present invention is to provide a connection structure capable of grounding a reinforcing bar with a simple operation and with certainty.

Means and effects for solving the problems

  In order to achieve the above object, the first invention is a connection structure for electrically connecting a reinforcing bar and an electric wire by a crimping terminal, and allowing a current flowing through either the reinforcing bar or the electric wire to escape to the other, The crimping terminal has a reinforcing bar crimping part that holds the reinforcing bar and adheres to the reinforcing bar by applying pressure.

  According to this configuration, the crimp terminal that electrically connects the reinforcing bar and the electric wire has the reinforcing bar crimping part that is in close contact with the reinforcing bar by applying pressure, and the reinforcing bar crimping part can be easily connected to the reinforcing bar. It becomes easy to connect to the electric wire. In addition, when a reinforcing bar and an electric wire are electrically connected by welding, thermal stress is generated during welding, and the strength of the reinforcing bar is reduced. As a result, the structure of a building or the like that uses the reinforcing bar Although there is a possibility that the strength may be reduced, the reinforcing bars and the electric wires can be electrically connected without reducing the strength of the reinforcing bars by connecting them by pressure bonding. Furthermore, since it connects by crimping | compression-bonding, even if protrusion parts, such as a node, are provided in the surface of a reinforcing bar, it can be made to contact | adhere to a reinforcing bar reliably. Therefore, the reinforcing bar can be reliably grounded.

  Further, the second invention is a connection structure for electrically connecting a reinforcing bar and an electric wire by a crimping terminal and letting the current flowing in one of the reinforcing bar and the electric wire escape to the other. Holds and has a reinforcing bar crimping part that is in close contact with the reinforcing bar by applying pressure, and has a wire crimping part that is brought into close contact with the electric wire by holding the electric wire and applying pressure, and is electrically integrated with the reinforcing bar crimping part. Yes.

  According to this configuration, the crimp terminal that electrically connects the reinforcing bar and the electric wire has a reinforcing bar crimping part that is in close contact with the reinforcing bar by applying pressure, and a wire crimping part that is in close contact with the electric wire by applying pressure. The rebar crimping part can be easily connected to the rebar, and the wire crimping part can be connected to the electric wire. Thereby, the connection of a reinforcing bar and an electric wire becomes easy. In addition, when a reinforcing bar and an electric wire are electrically connected by welding, thermal stress is generated during welding, and the strength of the reinforcing bar is reduced. As a result, the structure of a building or the like that uses the reinforcing bar Although there is a possibility that the strength may be reduced, the reinforcing bars and the electric wires can be electrically connected without reducing the strength of the reinforcing bars by connecting them by pressure bonding. Furthermore, since it connects by crimping | compression-bonding, even if protrusion parts, such as a node, are provided in the surface of a reinforcing bar, it can be made to contact | adhere to a reinforcing bar reliably. Therefore, the reinforcing bar can be reliably grounded.

  3rd invention contains the structure which connected the several reinforcing bar continuously in the 1st or 2nd invention by electrically connecting an electric wire and another reinforcing bar with a crimp terminal.

  According to this configuration, by connecting a plurality of reinforcing bars continuously, for example, even when it is desired to ground a reinforcing bar at a high place, it is necessary to provide a special long electric wire that connects to the reinforcing bar at a high place. By connecting them continuously, you can easily ground the reinforcing bars at high places.

  In a fourth aspect of the invention, the rebar crimp terminal according to any one of the first to third aspects is in close contact with the rebar in a state of surrounding the rebar by applying pressure. According to this configuration, since the reinforcing bar crimping terminal is connected to the reinforcing bar in a state of surrounding the reinforcing bar, the reinforcing bar crimping terminal is not easily detached from the reinforcing bar. Therefore, the connection strength can be increased. Moreover, even when the reinforcing bars have irregularities, the bonding area with the reinforcing bar crimping terminal can be increased as much as possible. In addition, this makes it possible to reduce the contact resistance of the connecting portion and reduce the generation of heat during energization.

  In the fifth invention, the wire crimping portion of any one of the second to fourth inventions comes into close contact with the reinforcing bar in a state of surrounding the wire by applying pressure. According to this configuration, since the wire crimping portion is connected to the electric wire in a state of surrounding the electric wire, the wire crimping portion is not easily detached from the electric wire. Therefore, the connection strength can be increased.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

  For example, as shown in FIG. 2, the connection structure according to the present embodiment is suitably used for a building 100 having a lightning rod facility 101 for avoiding damage from lightning. The lightning rod equipment 101 is usually installed in an upper layer such as the rooftop of the building 100. Even if the lightning rod equipment 101 is simply installed on the rooftop or the like, it cannot capture lightning unless it is grounded, and cannot protect the building from lightning damage. For this reason, in order to ground the lightning rod equipment 101 inside a pillar or the like that constructs the building 100, an energization path is provided from the roof of the building 100 to the grounding portion of the ground.

  Specifically, the building 100 is, for example, a reinforced concrete building constructed by a PC method, and is constructed of a large number of PC members (precast concrete members). In addition, the method of assembling reinforced concrete members manufactured on the factory line in the field is called the PC method, and the columns, beams, walls, floor boards, roofs, etc. to be assembled are called PC members. Then, reinforcing bars are buried in advance in the manufacturing stage at the factory inside the pillars which are the PC members, and the reinforcing bars buried in the upper floor pillars and the lower floor pillars are electrically connected at the construction site of the building 100. By constructing the PC member while connecting to the lightning rod, it is possible to connect the lightning rod equipment 101 installed on the rooftop of the building 100 and the grounding portion on the ground. This connected rebar is used as an energization path for grounding the lightning rod equipment 101.

  And the connection structure of this Embodiment is used suitably for the connection part which connects said reinforcing bars. Hereinafter, the connection part which connects the pillar 5 of the upper floor and the pillar 5 of the lower floor, and the connection structure used for this connection part are explained in full detail.

  As shown in FIG. 3, the upper floor pillar 5 and the lower floor pillar 5 are connected to each other through a beam 6 that is a horizontal member placed on the pillar to fix the pillar. The beam 6 has a hole 6a from the upper surface to the lower surface, and the rebar 1 provided in the column 5 described later can be penetrated. In addition, the beam 6 is previously provided with a wire 6b in parallel with the hole 6a at the time of manufacture at the factory. The electric wire 6b is provided so that the upper and lower tip portions protrude from the beam 6, and is connected to the electric wire 3 of the pillar 5 described later.

  On the other hand, the pillar 5 is a substantially rectangular parallelepiped material that supports a floor or the like that constructs each floor, and the pillar 5 has a substantially cylindrical reinforcing bar 1 and a connecting portion 2 such as a splice sleeve embedded therein. The reinforcing bar 1 is a main reinforcing bar of the column 5, and is embedded along the height direction of the column 5 so as to protrude vertically from the upper end portion 5 b of the column 5. The reinforcing bar 1 is inserted from the upper part of the connecting part 2 described later, and is embedded so that the lower part of the reinforcing bar 1 is located inside the connecting part 2. The connecting portion 2 is formed in a substantially rectangular shape that protrudes vertically from the lower end portion 5 a of the column 5. And from the lower part of this connection part 2, the reinforcement 1 of the pillar 5 of a lower floor can be inserted now. More specifically, the reinforcing bar 1 of the column 5 on the lower floor is inserted into the hole 6 a from the lower side of the beam 6 and protrudes to the upper side of the beam 6. Such a protruding portion can be inserted into the connecting portion 2 from the lower portion of the connecting portion 2 of the pillar 5 on the upper floor.

  In FIG. 3, only one reinforcing bar 1 is embedded in the column 5, but a plurality of reinforcing bars 1 may be embedded in the column 5 at equal intervals, and the number of reinforcing bars 1 is determined according to the strength of the column 5. It may be changed.

  The connection part 2 is provided with horizontal horizontal holes 2a and 2b in the upper part and the lower part, respectively, so that concrete, mortar, etc. can be injected into the connection part 2 and inserted into the connection part 2. The reinforcing bar 1 can be fixed. Specifically, in a state where the reinforcing bar 1 is inserted into the connecting portion 2, when mortar or the like is continuously injected from the horizontal hole 2b provided in the lower portion, the connecting portion 2 is filled with mortar and is provided in the upper portion. It overflows from the horizontal hole 2a. Thereby, the inside of the connection part 2 can be filled reliably. Then, by filling the connecting portion 2 with mortar or the like in this way, the reinforcing bar 1 can be fixed in the inserted state in the connecting portion 2, and the upper floor pillar 5 and the lower floor pillar 5 are joined via the beam 6. It can be done.

  As described above, the reinforcing bar 1 of the upper floor pillar 5 fixed in the connecting portion 2 and the reinforcing bar 1 of the lower floor pillar 5 are electrically connected by the electric wires 3 and 6b. Specifically, the reinforcing bar 1 and the electric wire 3 are electrically connected by the crimp terminal 10 attached to the reinforcing bar 1 of the column 5, and the electric wire 3 of the upper column 5 and the lower column 5 is described above. By connecting to the wire 6b embedded in the beam 6 in advance, the reinforcing bar 1 of the column 5 on the upper floor and the reinforcing bar 1 of the column 5 on the lower floor are electrically connected by the wires 3 and 6b. Yes.

  Here, the crimp terminal 10 will be described. The crimp terminal 10 is made of a metal plate such as copper or copper alloy, and can be electrically connected to the reinforcing bar 1 and the electric wire 3 by being connected to the reinforcing bar 1 and the electric wire 3 by crimping. As shown in FIG. 1A, the crimp terminal 10 includes a reinforcing bar crimping portion 11 that crimps the reinforcing bar 1 and the electric wire 3 so as to be substantially parallel to each other, and an electric wire that is crimped to the electric wire 3. The crimping part 12 is integrally formed. In addition, the oblique line drawn on the reinforcing bar 1 shown in FIG. 1A is a node 1a provided on the outer peripheral surface in order to improve the adhesion performance between the reinforcing bar 1 and the concrete. In addition, although the node 1a is helical in the figure, there are various shapes such as a mesh shape.

  The reinforcing bar crimping portion 11 has tip portions 11a and 11b, and has a substantially U shape with an opening between the tip portions 11a and 11b. And by inserting the reinforcing bar 1 from between the front end portions 11a and 11b so that the reinforcing bar 1 fits into the U-shaped groove, the reinforcing bar 1 can be held as shown in FIG. Yes. Similarly, the wire crimping portion 12 has tip portions 12a and 12b, and has a substantially U shape with an opening between the tip portions 12a and 12b. And as shown in FIG.1 (b), the electric wire 3 can be clamped now by inserting the electric wire 3 from between front-end | tip parts 12a * 12b so that the electric wire 3 may fit in a U-shaped groove | channel. Yes. The crimp terminal 10 is formed in a substantially infinite shape so that the above-described crimp portions 11 and 12 are integrated so that the tip portions 11a and 11b and the tip portions 12a and 12b are located on opposite sides. Yes. In addition, the crimping | compression-bonding part 11 * 12 has a magnitude | size according to each width | variety so that the reinforcing bar 1 and the electric wire 3 can be clamped reliably.

  As described above, a large compressive load is applied to the crimping terminal 10 sandwiching the reinforcing bar 1 and the electric wire 3 with a tool (not shown), and as shown in FIG. 1 (c), the tip portions 11a and 11b and the tip portions 12a and 12b are formed. The crimping portions 11 and 12 are plastically deformed until they are brought into close contact with each other, whereby the crimping portion 11 and the reinforcing bar 1 are brought into close contact with each other, and the crimping portion 12 and the electric wire 3 are brought into close contact with each other. In addition, the electric wire 3 is specifically crimped | bonded in the state from which the insulation coating of the electric wire 3 was removed beforehand. Thus, by making the crimping terminal 10 closely contact with the reinforcing bar 1 and the electric wire 3, the crimping terminal 10, the reinforcing bar 1, and the electric wire 3 can be made difficult to be separated from each other. Can be strong. Moreover, even when the reinforcing bars are uneven, the bonding area with the crimp terminal can be increased as much as possible. In addition, this makes it possible to reduce the contact resistance of the connection portion, and to reduce the generation of heat at the time of energization, specifically, lightning.

  Thus, since the crimp terminal 10 is connected to the rebar 1 by crimping, the rebar 1 and the electric wire 3 can be easily electrically connected. For example, in comparison with welding, the crimp terminal 10 can be easily provided. Therefore, even if the crimp terminal 10 is not provided on the reinforcing bar 1 in the manufacturing process at the factory, an operator at the construction site can use it. The crimping terminal 10 can be easily attached, and the reinforcing bar 1 and the electric wire 3 can be electrically connected by the crimping terminal 10. Further, since the connection by the crimp terminal 10 only applies a large compressive load to the tool, the connection work can be easily performed even when the work space is small. There is no need to provide a space, and the degree of freedom of the structure can be expanded, for example, the space between the pillar 5 and the beam 6 can be reduced.

  Moreover, when connecting the reinforcing bar 1 and the electric wire 3 by welding, a thermal stress is generated during welding, the strength of the reinforcing bar 1 is reduced, and the structural strength of the building 100 is reduced. By connecting, the reinforcing bar 1 and the electric wire 3 can be electrically connected without reducing the strength of the reinforcing bar 1. Furthermore, as described above, since the reinforcing bar 1 is provided with the node 1a, the surface of the reinforcing bar 1 has irregularities, but the crimping portions 11 and 12 are plastically deformed. Can be securely attached to the rebar 1. As a result, the reinforcing bar 1 can be reliably grounded. In addition, in order to plastically deform the crimping parts 11 and 12, if the crimping parts 11 and 12 are manufactured to be larger than the size (diameter) of the rebar 1 having a general size, it can be used for various reinforcing bars 1. become able to.

  In addition, you may make it connect the crimp terminal 10 and the electric wire 3 not by the connection by crimping but by other connection methods, for example, press contact. In the case of pressure welding, since it is not necessary to remove the insulation coating of the electric wire 3 in advance, the connection work can be facilitated. Moreover, the shape of the crimp terminal 10 may not be the above-described shape. For example, the crimping portions 11 and 12 of the crimp terminal 10 are formed in a substantially U-shaped groove shape, but may be formed in a square groove shape or the like. Moreover, according to the corresponding part of the electric wire 3, it is also possible to adjust the groove width suitably, for example, the groove | channel of the outer skin part of the electric wire 3 is wide, and that of a conductor part is narrow.

  As described above, the electric wire 3 electrically connected to the reinforcing bar 1 by the crimp terminal 10 is connected to the electric wire 6 b provided in advance on the beam 6 by another crimp terminal 15. Thereby, the reinforcement 1 of the pillar 5 of the upper floor and the pillar 5 of the lower floor can be made into the state electrically connected by the electric wire 3 and the electric wire 6b. Then, by repeating the above structure from the roof top of the building 100 to the installation part on the ground, the lightning rod equipment 101 can be grounded using the reinforcing bar 1 electrically connected by the electric wires 3 and 6b as an energization path. ing.

  In addition, the connection between the electric wire 3 and the electric wire 6b may not be by crimping but may be connected by pressure welding or other methods. Further, a reinforcing bar may be embedded in the beam 6 instead of the electric wire 6 b, and the reinforcing bar and the electric wire 3 of the column 5 may be electrically connected by the above-described crimp terminal 10. Moreover, you may make it connect the electric wire 3 of the pillar 5 of an upper floor and the electric wire 3 of the pillar 5 of a lower floor directly.

  As described above, in each floor, the reinforcing bar 1 of the upper floor pillar 5 and the reinforcing bar 1 of the lower floor pillar 5 are electrically connected by the electric wires 3 and 6b to be installed on the roof of the building 100. The current-carrying path of the lightning rod equipment 101 can be provided, and the lightning rod equipment 101 can be reliably grounded.

  In this embodiment, the case where the connection structure using the crimp terminal 10 is used for the building 100 including the lightning rod equipment 101 is described. However, the connection structure of the present invention may be used for another building or the like. . For example, various medical devices are installed in hospitals. In order to ground these medical devices, such a connection structure may be used in a hospital building, or in other buildings that need to be grounded. If there is, it can be suitably used. The material of the crimp terminal 10 is not particularly limited as long as the reinforcing bar 1 and the electric wire 3 can be electrically connected to each other, and the contact resistance of the connection portion can be more reliably connected. In order to make it smaller, the reinforcing bars 1 and the electric wires 3 may be appropriately pretreated and then connected by the crimp terminals 10.

  As described above, the present embodiment is a connection structure for electrically connecting the reinforcing bar 1 and the electric wire 3 by the crimp terminal 10 and letting the current flowing through either the reinforcing bar 1 or the electric wire 3 to the other. And the crimp terminal 10 has the reinforcing bar crimping part 11 which holds the reinforcing bar 1 and adheres to the reinforcing bar 1 by applying pressure.

  According to this configuration, the crimp terminal 10 that electrically connects the reinforcing bar 1 and the electric wire 3 has the reinforcing bar crimping part 11 that is in close contact with the reinforcing bar 1 by applying pressure, and the reinforcing bar crimping part 11 can be easily connected to the reinforcing bar. 1 can be connected to the rebar 1 and the electric wire 3 easily. Moreover, when the reinforcing bar 1 and the electric wire 3 are electrically connected by welding, a thermal stress is generated during welding, and the strength of the reinforcing bar 1 is reduced. As a result, the building using the reinforcing bar 1 Although the structural strength of 100 may be reduced, the reinforcing bars 1 and the electric wires 3 can be electrically connected without reducing the strength of the reinforcing bars 1 by connecting them by pressure bonding. Furthermore, since it connects by crimping | bonding, even if projection parts, such as a node 1a, are provided in the surface of the reinforcing bar 1, it can be made to contact | adhere to the reinforcing bar 1 reliably. Therefore, the reinforcing bar 1 can be reliably grounded.

  Further, in the present embodiment, the connection structure for electrically connecting the reinforcing bar 1 and the electric wire 3 by the crimping terminal 10 and letting the current flowing through one of the reinforcing bar 1 and the electric wire 3 to the other is provided. The terminal 10 holds the reinforcing bar 1 and applies pressure to the reinforcing bar crimping part 11 that is in close contact with the reinforcing bar 1, and holds the electric wire 3 and applies pressure to closely contact the electric wire 3 and is electrically integrated with the reinforcing bar crimping part 11. And a wire crimping portion 12 provided on the wire.

  According to this structure, the crimp terminal which electrically connects a reinforcing bar and an electric wire applies the pressure, the reinforcing bar crimping part 11 which adheres to the reinforcing bar 1, and the electric wire crimping part 12 which adheres to the electric wire 3 by applying pressure. The rebar crimping part 11 can be easily connected to the rebar 1 and the wire crimping part 12 can be connected to the electric wire 3. Thereby, connection with the reinforcing bar 1 and the electric wire 3 becomes easy. Moreover, when the reinforcing bar 1 and the electric wire 3 are electrically connected by welding, a thermal stress is generated during welding, and the strength of the reinforcing bar 1 is reduced. As a result, the building using the reinforcing bar 1 is used. Although there is a possibility that the structural strength of an object or the like may be reduced, the rebar 1 and the electric wire 3 can be electrically connected without reducing the strength of the rebar 1 by connecting by crimping. Furthermore, since it connects by crimping | bonding, even if the nodes 1a, such as a node, are provided in the surface of the reinforcing bar 1, it can be made to contact | adhere to the reinforcing bar 1 reliably. Therefore, the reinforcing bar 1 can be reliably grounded.

  Furthermore, in this Embodiment, the structure which connected the some rebar 1 continuously by electrically connecting the electric wire 3 to the other rebar 1 by the crimp terminal 10 is included. According to this configuration, by connecting a plurality of reinforcing bars 1 continuously, for example, even when it is desired to ground the lightning rod equipment 101 at a high place, a special long electric wire connected to the lightning rod equipment 101 at a high place. It is not necessary to provide 3 etc., By connecting continuously, the lightning rod equipment 101 in a high place can be earth | grounded easily.

  Further, the reinforcing bar crimping terminal 11 of the present embodiment is in close contact with the reinforcing bar 1 in a state of surrounding the reinforcing bar 1 by applying pressure. According to this configuration, since the reinforcing bar crimping terminal 11 is connected to the reinforcing bar 1 in a state of surrounding the reinforcing bar 1, the reinforcing bar crimping terminal 11 is not easily detached from the reinforcing bar 1. Therefore, the connection strength can be increased. Further, even if the reinforcing bars have irregularities, the bonding area with the reinforcing bar crimping terminal 11 can be increased as much as possible. In addition, this makes it possible to reduce the contact resistance of the connection portion and reduce the generation of heat during a lightning strike.

  Furthermore, the electric wire crimping part 12 of this Embodiment closely_contact | adheres to the reinforcing bar 1 in the state which surrounded the electric wire 3 by applying a pressure. According to this configuration, since the wire crimping portion 12 is connected to the wire 3 in a state of surrounding the wire 3, the wire crimping portion 12 is not easily detached from the wire 3. Therefore, the connection strength can be increased.

  As a modification of the crimp terminal 10 of the present embodiment, a crimp terminal 16 as shown in FIGS. 4A and 4B may be used. The crimp terminal 16 has a configuration in which the reinforcing bar crimping portion 14 and the wire crimping portion 15 are separately formed and electrically connected by the wire 13. Further, the tip portions 14a and 14b of the reinforcing bar crimping portion 14 and the tip portions 15a and 15b of the wire crimping portion 15 are crimped to the reinforcing bar 1 and the wire 3 without being in close contact with each other. By connecting the reinforcing bar crimping part 14 and the electric wire crimping part 15 with the electric wire 13, the reinforcing bar 1 and the electric wire 3 can be isolated and connected. The rebar 1 and the electric wire 3 can be connected to each other. In addition, the reinforcing bar 1 and the electric wire 3 can be bonded to the reinforcing bar 1 and the electric wire 3 in a state where the distal ends of the reinforcing bar crimping part 14 and the electric wire pressing part 15 are not in close contact with each other, regardless of the diameter (thickness) of the reinforcing bar 1 and the electric wire 3. Can be connected.
