BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a molding method in which a tape-shaped molding joint material is adhered to a joint between a pavement and a road structure such as a curb or a median strip to prevent rainwater from entering. A joint material bonding construction device.

[0002]

2. Description of the Related Art Conventionally, a method for bonding molding joint materials is to remove dirt by previously rubbing the sides of road structures such as dirty pavements and curbs with a brush etc. After applying the solvent-type primer, the tape-shaped adhesive joint material is attached to the road structure such as pavement or curb by pressing it by hand.

Before the above-mentioned bonding work, if necessary, a burner is applied to the back surface of the molding joint material to improve the familiarity between the molding joint material and the road structure, and the adhesion between the road portion and the molding joint material is improved. Plan.

[0004]

However, in the above-mentioned conventional method for bonding and forming the molding joint material, when the molding joint material is adhered to the side surface of the road structure such as the curbstone or the median strip,
Since the molding joint material is manually bonded to the side surface of the road structure, it is difficult to bond the molding joint material horizontally along the side surface of the road structure. There is a problem that it takes time and effort to bond them.

The present invention has been made in view of the above-mentioned problems, and mechanizes the dirt removal of the side surface of the road structure to which the molding joint material is adhered and the operation of adhering the molding joint material to the side surface. The purpose is to facilitate the bonding of molded joint material to the side of road structures.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and relates to a carriage that can be moved along a road structure such as a curbstone or a median strip, and the carriage. A support part that is provided and supports a roll formed by winding a tape-shaped and adhesive forming joint material, and a rolling member that is supported by a trolley and sequentially presses the forming joint material onto the side surface of the road structure. A possible roller, a roller arm that connects the roller to the carriage and biases the roller from the carriage to the side of the road structure, and a side surface of the road structure supported by the carriage in front of the roller. A rotating brush that is pressed against, a rotating brush arm that connects the rotating brush and the carriage, and urges the rotating brush from the carriage to the side surface side of the road structure; and the rotating brush that is mounted on the carriage. Rotate the brush It is characterized by comprising a rolling brush driving device.

The roller arm and the rotary brush arm may be formed as an integral arm. Also, the roller is provided on an outer cylinder portion, a rotation shaft provided at the center of rotation of the outer cylinder portion and rotatable with respect to the outer cylinder portion, and the roller is attached to one side surface of the rotation shaft, A rotating shaft drive device may be provided that is configured of an eccentric weight that generates lateral vibration when the shaft rotates, and that is mounted on the carriage to rotate the rotating shaft. At this time,

First, the outer end portion of the molding joint material supported by the support portion is pulled out, and the outer end portion is brought into contact with the side surface of the road structure and pressed against the side surface by the roller. Next, when the truck is moved along the road structure, the rollers also roll along the side surface of the road structure following the movement of the truck,
Sequentially, the molded joint material is pulled out and pressed against the road structure, so that the molded joint material is adhered to the side surface of the road structure.

At this time, before the molding joint material is adhered to the side surface of the road structure by the roller, a rotating brush supported by the carriage in front of the roller scrapes the adhering surface of the road structure. The dirt adhering to the surface is removed to suppress the adhesion failure of the molding joint material. Further, as described in claim 2, when the roller is composed of an outer cylinder portion and a rotation shaft that are rotatable relative to each other, the roller rolls while pressing the molding joint material along the side surface of the road structure. The rotating shaft is rotated by the rotating shaft driving device separately from the outer cylinder part of the.

At this time, the rotating shaft rotates while causing axial runout in the lateral direction due to the eccentric weight, and the vibration is transmitted to the outer cylinder portion and is interposed between the outer cylinder portion and the road structure. The formed joint material is hit against the side surface of the road structure, and the pressing of the formed joint material against the side surface of the road structure is further improved. Further, when the side surface of the road structure cleaned by the rotating brush is heated by the burner, the adhesiveness of the molding joint material to the side surface becomes strong, and the side surface of the road structure and the molding joint material become more familiar.
