Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pavement for a road bridge in which a widthwise end of a material to be laid on the surface of the steel plate is regulated by a regulating member when the surface of the steel plate which is the floor of the road bridge is paved. The present invention relates to a method and a paving tool for positioning and fixing the regulating member to an end portion of a material to be paved.

[0002]

2. Description of the Related Art In order to perform paving on a steel sheet surface 1a which is a floor of a road bridge 1, when asphalt 2 as a material to be paved is laid on the steel sheet surface 1a, the widthwise dimension of the asphalt 2 is designed. In order to regulate the size, the rafter 3 as a regulating member is previously positioned and fixed at a predetermined position on the steel plate surface 1a to regulate the width direction of the asphalt 2. Conventionally, as a method of positioning and fixing the above-mentioned rafter 3 on the steel plate surface 1a, as shown in the cross-sectional view of FIG. 8, the paved material (on the side opposite to the pavement restricting surface of the rafter 3 that abuts the end of the asphalt 2) By means of the fixing means 60 in which the asphalt 2 is packed, the rafter 3 is positioned and fixed to perform paving.

[0003]

However, according to the above-mentioned pavement method, the fixing means 60 for positioning and fixing the rafter 3 when the rafter 3 is removed after the paving is completed adheres to the steel plate surface 1a. Therefore, it is difficult to remove the fixing means 60, and there is a problem that the processing after the removal is troublesome. Further, since it is difficult to remove the fixing means 60, if an impact is applied to the fixing means 60, the rafter 3 is also impacted,
As a result, there is also a problem that the regulated end of the paved asphalt 2 collapses.

Therefore, in order to solve the above problems, the present invention can easily perform positioning and fixing and removal of a rafter for controlling the end of the material to be paved when paving the steel plate surface of the road bridge. It is an object of the present invention to provide a paving method for a road bridge and a paving tool.

[0005]

In order to achieve the above-mentioned object, the method of paving a road bridge according to the present invention is such that when the paving material 2 is laid on the floor of the road bridge 1 and paving is performed, both sides of the paving material 2 are covered. A method for paving a road bridge, in which a regulating member 3 is preliminarily positioned and fixed on a floor surface of a road bridge 1 along an edge, and a paving material 2 is laid between the regulating members 3 on both sides to perform paving. On the steel plate surface 1a, which is the floor of the bridge 1, a paving tool 4 that comes into contact with the outer side surface of the regulation member 3 and regulates the outward movement of the regulation member 3 is magnetically attached by a magnetic force so as to be removable. It is characterized by being provided by. In addition, in order to perform paving on the floor of the road bridge 1, the paving tool according to the paving method for the road bridge positions and fixes the regulating member 3 that regulates the widthwise end of the paved material 2 laid on the floor. In a paving tool for a road bridge, magnetically adhere to the steel plate surface 1a which is the floor of the road bridge 1,
It is characterized in that a magnetic attachment 10 for positioning and fixing the regulating member 3 at a regulating position which is an end portion of the paved material 2 is provided. Further, a detaching means 12 which is provided on the magnetic attachment 10 and separates the magnetic attachment 10 from the steel plate surface 1a may be provided. Further, there may be provided attachments 20, 30, 40, 50 which engage with the magnetic attachment 10 to fix the regulating member 3 and position the regulating member 3 at a regulating position which is an end of the paved material 2. .

[0006]

The regulating member 3 is positioned and fixed at the regulating position in the width direction of the designed material 3 to be paved by the magnetic attachment 10 magnetically attached to the steel plate surface 1a for paving. Further, the magnetic attachment 10 is peeled off from the steel plate surface 1a by the detaching means 12, whereby the regulating member 3 is detached from the fixed position. Further, the restriction member 3 is fixed to the fixtures 20, 30, 40, and 50 that engage with the magnetic fitting 10, so that the magnetic fitting 10 after paving is peeled off from the steel plate surface 1a. The paving material 2 is removed from the regulated position.
