As an alternative to preventing pollution and reducing dependence on petroleum energy, electric vehicles driven only by electricity and hybrid vehicles using electric and internal combustion engines have been developed.

However, electric vehicles and (plug-in) hybrid vehicles developed to date have to be connected to an external power supply device for a long time by using a plug or the like to charge a battery, and there is a long distance to operate with only one charge. It has the disadvantage of being limited.

Therefore, in recent years, a self-induction electric vehicle has emerged again as an alternative to electric vehicles using batteries.

A self-induction electric vehicle requires a feeding road to supply electricity. In order to serve as a feed road (or feed rail), a feed rail structure including ferrite cores and feed lines should be installed to maintain a constant distance from the ground, which must be durable against vehicle loads, and the structure is thermally expanded due to thermal expansion. It should be possible to cushion the stress concentration so as not to break.

The feed rail structure should be of sufficient thickness to withstand the load of the vehicle, have ferrite cores inside, and contain duct space for cables to pass through. The feed rail of this shape can be produced by precasting in the form of a module.

However, since the feed rail module designed in consideration of the load of the vehicle has a considerable weight, it is difficult to transport and the site construction using the same is not easy.

Therefore, there is an urgent need to develop a method for constructing a feed rail directly on site.

(Step 1: Cut the road, see Figure 6)

First, the road of the portion where the feed road is to be cut is cut to a predetermined depth and width. In order to form a feed road or a feed rail, a ferrite core assembly, a pipe assembly for power lines, and various cables must be installed. As shown in FIG. 6, the existing road surface 200 is cut to form the cutout 202. There is a need. In addition, since the feed road should have sufficient durability against the load by the vehicle traveling on the feed road, when cutting the existing road surface 200 in consideration of these parts to cut or excavate the road surface or ground to a sufficient depth It is good.

In addition, the incision of the existing road surface 200 should be dug in the center of the lane to be used for driving the on-line electric vehicle so as to face the current collector attached to the lower direction of the on-line electric vehicle. It is desirable to have a corresponding, but slightly wider than the width of the ferrite core.

On the other hand, when constructing concrete pavement where there is no existing road, the width of the joint formwork can be modified in accordance with the width of the road to be constructed in a similar way.

(Step 2: Installation of the fixing formwork, see FIG. 7)

When the incision 202 is formed by cutting the existing road surface 200, the mounting (joint) formwork 10 for mounting in a predetermined length unit. Here, the second step is a process is made for each section, the mounting formwork 10 is installed at each end of each section of the partitioning unit for a certain length (one piece each).

On the other hand, the mounting formwork 10, as shown in Figure 2, the alignment projection 12 and the common groove pipe mounting groove 14 and the core for ease of installation and easy placement of the feed road components A mounting groove 16 for assembly and a mounting groove 18 for power line pipe. Alignment protrusion 12 is formed to protrude horizontally along the width direction of the road on both sides of the mounting formwork (10). The protruding alignment protrusion 12 is generally seated on the existing road surface 200 which is not cut in the shape of an ear, and fixes the mounting formwork 10 so that the mounting formwork 10 does not fall or bend. Formwork for 10 to maintain the gap between the existing road surface 200. The common groove pipe mounting groove 14 is formed in the center portion of the mounting formwork 10, the core assembly mounting groove 16 is formed on the left and right sides based on the common groove pipe mounting groove 14, respectively. The power line pipe mounting groove 18 is formed between the common line pipe mounting groove 14 and the core assembly mounting groove 16, respectively. The mounting grooves 14, 16, and 18 thus formed are upwards from the mounting formwork 10 so that the corresponding components (common line pipe, core assembly, power line pipe) can be mounted from above the mounting formwork 10. It extends downward from. For reference, among the mounting grooves, the mounting groove 14 for the common line pipe which has little effect on the electric vehicle is formed to extend the longest (downward), and the mounting grooves 14 for the core assembly and the power line pipe affecting the electric vehicle. 18 is extended relatively short so as to maintain a relatively short distance from the surface with the feed.

On the other hand, if you want to include the sensor signal line and the like in the rain structure, the additional pipe to be inserted into the sensor signal line should be included in the rail structure, the mounting groove 10 for this in the mounting formwork 10 and the fixed formwork (60) Add However, if necessary, the sensor signal lines can be provided together with the common line pipe.

(Step 3: Installation of the feeder road components, see FIGS. 8 to 10)

After the installation of the mounting formwork 10, the components of the feeder road (common line pipe, ferrite core assembly, power line pipe) are sequentially installed as shown in Figs.

First, the common line pipe 22 having the longest mounting groove is installed in such a manner as to span the corresponding mounting groove 14, and then the ferrite core assembly 40 is installed in the corresponding mounting groove 16, and then The power line pipe 28 is installed in the mounting groove 18.

Here, the common line pipe 22 and the power line pipe 28 are prepared in units of a predetermined length (or referred to as a module unit) divided by a pair of mounting formwork 10. And the pipe assemblies 20 comprising these pipes 22, 28 each comprise a coupling 24 so as to be able to be connected with the pipes 22, 28 of the neighboring zone as shown in FIG. 3. do. More preferably, the pipe assemblies 20 have a cylindrical coupling 24 having a diameter larger than the diameters of the pipes 22, 28 and an o-ring 26 installed inside the coupling 24. Include.

Each pipe assembly 20 connects the same kind of pipes 22, 28 inside the coupling 24 as shown in FIG. 3. Here, the O-ring 26 serves to block the gap between the coupling 24 and the pipes 22 and 28 to block concrete from penetrating into the coupling 24. The important point is that most of the pipes 22 and 28 expand / contract in the longitudinal direction by thermal expansion, so that the gaps must be provided so that the ends thereof do not contact each other in the coupling 24.

The ferrite core assembly 40 is prepared to fit the module unit, and includes a ferrite core 42, a vertical guide 44 and a horizontal guide 46. The ferrite core 42 generally takes the form of an E-shape laid sideways (in the case of the dual type) and is installed at regular intervals along the longitudinal direction of the cutout 202. The guides 44 and 46 are adhesively fixed to both sides of the ferrite cores 42 arranged at regular intervals, thereby serving as an anchor for fixing the spacing and the position of the ferrite cores 42. Here, the vertical guide 44 and the horizontal guide 46 are elongated in different directions to be mounted on different molds 10 and 60, respectively. That is, if the vertical guide 44 is mounted on the mounting formwork 10 and the fixing formwork 60 of the preceding module, the horizontal guide 46 is the mounting formwork 10 and the fixing formwork of the following module ( 60) is mounted. This structure connects the ferrite cores 42 (of the front module and the rear module), which are partitioned by the forms 10, 60, with relatively little interference.

After the installation of the ferrite core assembly 40, the power line pipe 28 is installed in the form shown in FIG.

(Step 4: Installation of the fixing formwork, see FIG. 11)

When the installation of the feed road construction is finished, the fixed formwork 60 is installed.

The fixing formwork 60 is fixed by fitting against the mounting formwork 10 and serves as an anchor for fixing and aligning the respective components (pipe assemblies 20 and ferrite core assembly 40). The combination of the fixed formwork 60 and the stationary formwork 10 is made by an X-shaped formwork fixing clip 70 (see FIG. 12).

On the other hand, the fixing formwork 60, as shown in Figure 5, the alignment projection 62 and the common groove pipe fixing grooves 64 and the core for ease of installation and easy placement of the feed road components A fixing groove 66 for the assembly and a fixing groove 68 for the power line pipe. The alignment protrusion 62 is formed to protrude horizontally along the width direction of the road at both sides of the fixing formwork 60. The protruding alignment protrusion 62 is generally seated on the existing road surface 200 which is not cut in the shape of an ear, and fixes the fixing formwork 60 so that the fixing formwork 60 does not fall or bend. Formwork for 60 to maintain the gap between the existing road surface 200. Fixing grooves 64 for common line pipes are formed in the central portion of the fixing formwork 60, and fixing grooves 66 for the core assembly are formed on the left and right sides based on the fixing line 64 for the common line pipes, respectively. The power line pipe fixing grooves 68 are formed between the common line pipe fixing grooves 64 and the core assembly fixing grooves 66, respectively. The fixing grooves 64, 66, and 68 formed as described above are mounted on the mounting formwork 10 so that the components (common line pipe, core assembly, power line pipe) can be stably fixed by the fixing formwork 60. Contrary to the grooves 14, 16, 18, they are formed extending from below to upward.

(Step 5: Repeat steps 2 through 4)

When one module forming a feed road of a certain length is completed through the above steps, modules of neighboring parts are repeatedly produced by performing steps 2 to 4 in turn.

(Step 6: Placing Concrete, see FIG. 13)

When the module of all sections of the feed road is completed through the fifth step, the concrete is poured as shown in FIG. 13, and the bubble remover 90 is inserted between the side surface and the incision surface of the ferrite core 42 to move and Rotating to remove bubbles at the bottom of the ferrite core assembly 40. Once the bubble is removed, the top surface is flattened and cured sufficiently to complete the feed rail structure.

On the other hand, the formwork is made of wood, such as plywood, and does not remove even after curing of the structure to play a role of preventing the stress of the structure from excessively increased during longitudinal expansion of the feed rail structure. In addition, in order to complete the feed road, various cable wiring work and sensor work are required, and a clean road surface can be formed by overlaying.

The construction process of this invention is summarized as follows.

First step: The center of the road is excavated to a certain width and a predetermined depth to form the cutout 202.

Second step: Fix the mounting joint formwork 10 on both sides to fit the length of the ferrite core assembly 40 and the pipe assembly 20 designed on the incision.

Step 3: The pipe assemblies 22 for the common line, the ferrite core assembly 40, and the pipe assembly 28 for the power line are sequentially mounted on both mounting joint forms.

Step 4: Fix the components by attaching the fixing joint formwork 60 to the mounting joint formwork 10 and fix the two formwork with the form fixing clip 70.

Step 5: Repeat steps 2 to 4 as needed for the length of the road or the amount of concrete to be poured.

Step 6: Place the concrete between the molds to which the component is fixed, and use the bubble remover 90 to remove bubbles that may occur at the bottom of the ferrite core assembly and to flatten the top surface.

Step 7: Curing the poured concrete to complete the structure.

The present invention made as described above overcomes the difficulty of aligning the precast weights to locations by placing concrete structures that are required to be placed within the construction site in modular units. In addition, the present invention has the advantage that the module can be repaired after the construction because it is installed in the module unit. Inserting the formwork between each module to prevent breakage due to longitudinal thermal expansion. The formwork is a plate made of wood such as plywood, which not only divides the module in the longitudinal direction of the road cut, but also cushions the thermal expansion between the modules. Plays a role. In addition, the joint formwork positions the internal components so that they can be placed in the designed position with respect to the road surface, and serves to fix the components when placing concrete. The area in which components are laid out using joint formwork becomes formwork for one feed rail structure module.
