摘要:
Two synthetic resin structural members (11) are connected by placing a connector (22) having a plurality of holes formed therein into engagement with the two members (11), drilling a hole in one of the members in a position corresponding to one of the holes in the connector and securing a blind rivet (23) in the aligned holes. The drilling and riveting steps are repeated until the required number of rivets have been secured in both the members. If one of the members is hollow, the connection to it of the connector may be supplemented or replaced by a bolt (32) which passes through the connector and through the hole in a sleeve which is received in opposed holes in the wall of the hollow member. The nut is then tightened and the sleeve prevents the walls of the hollow member being deformed inwardly.

A cooling tower includes a supporting framework (11) comprising interconnected vertical columns (12) of hollow tubular construction, horizontal beams (13) of solid construction and inclined braces (14) of hollow tubular construction, all of which are made of fibre reinforced plastic material.
摘要:
Synthetic resin structural members (11,11a) are inserted into a hollow joint member to abut each other in the joint member. A bearing-pressure damping member (15) is fitted into each bolt hole formed in the members. The axes of bolts (16) fitted in the holes extend alternately in mutually perpendicular directions. Due to damping action resulting from elastic deformation of the damping members, a load is substantially evenly disitributed over all the bolts to prevent concentration of the load on some of the bolts. The arrangement of the bolts with their axes extending alternately in mutually perpendicular two directions shortens the length of the joint member.
