On the other hand, the forward and reverse rotation drive motor 73 is operated by using the power of the generator at the work site.

The concrete surface separating member 90 is to flatten the concrete poured by the flattening device 20, and then to separate the concrete on the concrete surface before the concrete is cured.

The concrete surface separating member 90 is a horizontal plate 92 seated on the concrete upper surface is flattened by the flattening device 20, and the horizontal hole 94 formed in the longitudinal direction in the central region of the horizontal plate 92 Joint insertion jig 96 consisting of; It is composed of a space joint 100 is inserted through the horizontal slot 94 of the joint insertion jig 96 to separate the concrete surface.

At this time, the horizontal plate 92 constituting the joint insertion jig 90 is made of a suitable length for the road width, made of wood, metal panels or synthetic resin having a suitable width, the horizontal slot 94 is the length in the center area Penetrating in the direction, the space joint 100 is inserted.

The space joint 100 is made to maintain the thickness that can be inserted into the horizontal slot 94 of the joint insertion jig 90, and to maintain a width enough to sufficiently separate the concrete curing surface, the seasonal temperature difference It is made of hard rubber material with little change.

An operation state of the flattening apparatus according to the present invention configured as described above will be described.

1 to 6, first to flatten and stiffen the original road surface in order to pave the road, and then the concrete is poured to pave the road. That is, the first and second guide rails 11 and 12 constituting the formwork member 10 are properly fixed to the road surface to be assembled and maintained in the road width to be paved. Then, the first and second guide rails 11 and 12 are installed while maintaining the width and height appropriate for the road width, thereby providing a space for curing concrete.

In this state, the flattening device 20 is placed on the first and second guide rails 11 and 12 of the formwork member 10, and then concrete is mixed with gravel, sand, cement, etc. at an appropriate ratio. . These concrete mixtures are conveniently placed using ready-mixed concrete or other concrete placing equipment.

Next, the planarizing device 20 mounted on the first and second guide rails 11 and 12 of the formwork member 10 is operated. This will be described in detail as follows.

First, as shown in FIG. 4, the driving motor 73 of the rotating member 70 constituting the flattening device 20 is operated in a forward rotation. Then, the driving motor 73 in the upper portion of the frame 30 is operated in the forward rotation, accordingly, the first sprocket 71 of the tip of the motor shaft 72 and the second sprocket 74 of the horizontal power transmission shaft 75. As the rotation force of the drive motor 73 is transmitted to the horizontal power transmission shaft 76 by the chain 81 connected between the), and the second rotation shaft 64b built in the shaft coupling coupling 75 is rotated The second rotation wheel 67 is rotated.

At the same time, the third rotation wheel 68 is rotated by a chain 81 connected between the third sprocket 76 inside the second rotation shaft 64b and the fourth sprocket 77 inside the third rotation shaft 64c. The first rotation wheel 66 is rotated forward by a chain 81 connected between the fifth sprocket 78 outside the second rotation shaft 64b and the sixth sprocket 79 outside the first rotation shaft 64a. do.

Accordingly, the first, second and third rotation wheels 66, 67, and 68 move forward along the first guide rail 11, and the frame 30 moves forward, and the frame 30 ( 31) Both ends are rotatably arranged between the rotating bearings 52 fixed to correspond to the lower front, and the conveying screw 54 provided with the conveying blades 54a and 54b on the outer circumference is moved forward. .
Accordingly, the rotational force is transmitted to the opposite guide rail (12) so that the frame (31) and the rotating wheel (60) move forward along the guide rail (12) at the same time.
As such, the conveying screw 54 of the conveying screw member 50 moving forward is rotated by the poured concrete, that is, in the state in which the conveying blades 54a and 54b of the conveying screw 54 touch the concrete. As the transfer screw 54 moves forward, the transfer screw 54 rotates.
At this time, the conveying blades 54a and 54b are disposed in opposite directions with respect to the center area so that the cast concrete moves to both sides along the conveying blades 54a and 54b.

Then, by driving the drive motor 73 in the forward and reverse rotation to move the flattening device back and forth along the first and second guide rails (11) (12) can be quickly flattened before the poured concrete is hardened.

Meanwhile, as shown in FIGS. 7 to 9, the concrete is poured into a flattening apparatus, and then the joint insertion jig 96 constituting the concrete surface separating member 90 is used on the concrete surface before the concrete is cured. By inserting the space joint 100 of the rubber material to separate the curing surface to prevent the crack is generated after the concrete is cured.

Specifically, when the flattening of the concrete is made, the horizontal plate 92 constituting the joint insertion jig 96 made of wood, a metal panel or a synthetic resin having a suitable length for the road width and having an appropriate width is concrete. After seating on the surface, the space joint 100 is inserted through the horizontal hole 94 of the horizontal plate 92.

Then, the space joint 100 passes through the horizontal hole 94, passes through the poured concrete surface, adheres to the original bottom surface, and separates the proper interval between the concrete surfaces. To prevent it.

At this time, the space joint 100 is made of a hard rubber material is less deformation due to the temperature difference due to the elastic force of the concrete itself after curing, it is to prevent the breakage of itself.
