Synthetic resin structural members are inserted into a hollow joint member to abut each other in the joint member. A bearing-pressure damping member is fitted into each of bolt holes on the members, axes of bolts extend alternately in two mutually perpendicular directions. The structural members and the hollow joint member are secured with bolts and nuts. Due to damping action resulting from elastic deformations of the damping members, a load is substantially evenly distributed over the whole bolts to prevent concentration of the load to some of the bolts. The arrangement of the bolts with their axes extending alternately in two mutually perpendicular directions will shorten the length of the joint member.

Joint structure for synthetic resin structural members

A method for joining a structural member made of a synthetic resin such as fiber reinforced plastic (FRP) with a further synthetic resin or other structural member. The method is effective when using synthetic resin members instead of conventional lumber or steel members in a main framework of a cooling tower. FRP members increase the corrosion resistance and simplify the assembly of such towers.
