Laying Guide for Electric Wire

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire inflow guide bar, and more particularly, to a wire inflow guide bar provided on a building wall for providing a wire inflow space inside a building wall (concrete wall).

(Hereinafter referred to as "electric wire") is to be connected to an outlet, a switch, a telephone jack or the like (hereinafter referred to as "electric appliance") in an indoor space. For this purpose, .

The conventional wire entry space is provided with an outlet box inside the building wall to provide a wire entry space inside the building wall as disclosed in the registered utility model No. 20-0435649 (name of design: height adjustment device of outlet box) Method was used.

If there is a wire entry space in the inside of the building wall, the thickness of the area of the building wall where the outlet box is installed is reduced, thereby adversely affecting the structural safety or causing a problem of condensation of the wire entry space. A method of providing a wire entry space in the interior of the building wall (interior space side) by installing a wire entry guide bar on the building wall to expose the interior space of the building has been used.

Figs. 11 and 12 are exploded perspective views of a conventional wire infeed guide bar, respectively.

As shown in these drawings, the conventional wire infeed guide bar includes a guide bar body 110 having a support plate 111 on which three inflow guide holes 111a are formed, And a holding socket 130 coupled to the front and rear direction intake guide pipes 120 one by one.

The guide body 110 includes a plurality of fixing grooves 112 and three support tube portions 113 protruding from the back surface of the support plate 111 in addition to the support plate 111, A pair of guide rails 115 formed one by one on the outer surface of the support wall 114 opposite to the other support wall and a pair of guide rails 115 formed on the guide rails 115, A pair of binding pieces 116 provided one by one on the guide rails 115 so as to be movable linearly along the guide rails 115 and one on the outer surface of each support wall 114 so as to be arranged in a region between the guide rails 115 A pair of spring fixing plates 117 and a pair of springs 118 provided at both ends to be supported by the spring fixing plate 117 and the coupling pieces 116. [ In the present specification, the front surface means a surface when viewed in an indoor space in a state where a wire entry guide is installed, and the back surface means the opposite surface.

Each fixing groove portion 112 is formed with a fixing groove 112a which is open to the front.

Each support tube portion 113 is formed in an upright position in the peripheral region of the draw-in guide hole 111a.

The guide rails 115 of each group are formed with a stopper jaw 115a at an upper end thereof.

A reinforcing bar insertion groove 116a is formed in each binding piece 116 along a direction parallel to the plate surface of the supporting plate 111 and a sliding groove 116b is formed along a direction perpendicular to the plate surface of the supporting plate 111 .

Each engaging piece 116 is formed with a retaining jaw 116c and a spring seating groove (not shown) which engage with the stopper jaw 115a.

Each spring fixing plate 117 is formed with a spring fixing hole 117a.

Each of the springs 118 is installed such that one end thereof enters the spring seat groove (not shown) and the other end thereof is fixed to the spring seat 117a.

Each of the forward and backward direction intake guide pipes 120 has a forward and backward incoming guide straight line section 121 and an engagement flange section 122 extending outward from one end of the forward and backward incoming guide straight line sections 121. In this specification, the back and forth direction of the building wall means the thickness direction of the building wall.

The forward and backward incoming guide straight section 121 is formed with a male screw portion on its outer surface.

The forward and backward directional inlet guide pipe 120 having such a configuration is configured such that the forward and backward inlet guide straight line sections 121 communicate with the inlet guide holes 111a (through the support pipe sections) Rear direction of the wall, and the engaging flange portion 122 is disposed in contact with the front surface of the support plate 111. [

The holding socket 130 has a socket body portion 131 having a substantially circular tube shape and a plurality of elastic pieces 132 formed on the inner surface of one end of the socket body portion 131 so as to be arranged at regular intervals along the circumferential direction .

The socket body portion 131 is formed with a female screw portion on its inner surface.

Each of the resilient pieces 132 is bent at one end thereof toward the center of the socket body portion 131 by a restricting protrusion 132a.

The holding socket 130 having such a configuration is installed such that the socket body portion 131 is screwed to the forward and backward guiding guide straight section 121. In the state where the holding socket 130 is installed, the restricting jaw 132a prevents the electric wire entering the back-and-forth direction guiding pipe 120 from coming out again.

A method of using a conventional wire inflow guide having the above-described configuration will now be described with reference to FIG. It is assumed that a lateral reinforcing bar 202 and a longitudinal reinforcing bar 203 (see Fig. 7) for assembling the building wall body 201 are assembled for convenience of explanation. The horizontal reinforcing bars 202 refer to reinforcing bars disposed in a direction perpendicular to the height direction of the building wall and the vertical reinforcing bars 203 refer to reinforcing bars disposed in the height direction of the building wall.

A conventional wire infeed guide bar is installed so that the side reinforcing bars 202 enter the reinforcing bar insertion groove 116a.

Next, a corrugated pipe 204 is installed to enter the front-back direction inlet guide pipe 120.

Next, a mold for building the building wall is installed. Here, the formwork is installed so that the support plate 111 can be exposed to the interior space after the building wall body is installed.

Next, the concrete is poured into the formwork and the poured concrete is cured to form the building wall body 201.

Next, a heat insulating material layer 205 is formed on the inner surface of the building wall body 201 by using Styrofoam or the like. Here, the formation of the heat insulating layer 205 is performed such that the support plate 111 is exposed to the interior space.

Next, the interior material layer 206 is formed on the outer surface of the heat insulating material layer 205. [ The formation of the interior layer 206 is performed such that the interior of the interior space of the support plate 111 is exposed.

Next, electric wires are installed to pass through the corrugated pipe 204 and the inlet guide hole 111a to be exposed to the indoor space.

Finally, the electric device 207 is coupled to the support plate 111 by using the fixing groove 112a. Here, the coupling of the electric device 207 is made such that the electric device 207 is electrically connected to the electric wire.

However, according to the conventional wire infeed guide, there is a problem in that it is difficult to install the corrugated pipe 204 because the front-back direction inflow guide pipe 120 is disposed along the thickness direction of the building wall body 201 And the corrugated tube should be fixed to the lateral reinforcement, vertical reinforcement, etc.) to maintain the corrugation curve.

Further, since a large force is applied to the section of the corrugated pipe due to the concrete inserted when the concrete is poured, there is a problem that it is difficult to stably maintain the initial state of the corrugated pipe 204.

Since the separation distance between the corrugated pipe 204 and the outer surface of the building wall 201 is small in a state in which the building wall 201 is formed, So that the condensation phenomenon is severely generated according to the difference between the room temperature and the external temperature. As a result, there arises a secondary problem that electric leakage and safety accidents may occur.

Further, since the separation distance between the corrugated pipe 204 and the outer surface of the building wall body 201 is small in a state in which the building wall body 201 is built, there is a problem that a portion with weak strength is generated in the building wall body 201.
