On the end face orthogonal to the joint surface of any of the panel materials, the first hardware having A joining structure including at least a pin inserted into a pin hole provided in the first metal fitting and the second metal fitting through a horizontal through hole extending from a side surface of a provided construction hole toward the joint surface was used. It is a construction method of the surface structure,
The first metal fitting is fixed to the joint surface of the one panel material of the panel materials adjacent to each other among the plurality of continuous panel materials, and the second is attached to the joint surface of the other panel material. The hardware fixing process for fixing hardware and
A connecting step of inserting the insertion portion of the first hardware into the receiving hole formed by the second hardware, and a connection step.
At least the connection is made by passing the pin through the horizontal through hole extending from the side surface of the construction hole provided on the end surface orthogonal to the joint surface of any of the panel materials adjacent to each other toward the joint surface. A pin insertion step of inserting the pin into the pin hole provided in the first hardware and the second hardware connected in the process, and a pin insertion step.
Of the plurality of panel materials joined to each other in the connecting step and the pin insertion step, the panel materials at both ends are held, the entire plurality of panel materials are lifted, and the entire panel material is arranged at the installation location of the surface structure. Lifting arrangement process and
A method of constructing a surface structure, which is characterized by being provided with.
