Abstract
A pipe and socket connection for a spacial structure which is comprised of a pipe termination that is coaxial and welded to the end of the pipe and which possesses a hole in which a screw is able freely to rotate, the diameter of the screw head being greater than that of the hole in which it can rotate, a polygonally sectioned body and a threaded end, and where a nut having a polygonal inside shape engages upon the body of said screw, and where means are provided to restrict unwanted axial motion of the screw.
Claims4
A pipe and socket connection for spatial structures comprising:
- (a) a pipe termination that is coaxial with and welded to one end of the pipe, said pipe termination having a hole therein;
- (b) a screw that is freely rotatable in said hole of said pipe termination, said screw comprising:
- (b.sub.1) a head having a diameter greater than said hole of said pipe termination, said head positioned inside said pipe;
- (b.sub.2) a polygonal body connected to said head and extending through said hole to outside said pipe;
- and
- (b.sub.3) a threaded end connected to said polygonal body;
- (c) a nut having an inside polygonal area that mates with said polygonal body of said screw, said nut having an inside recess therein;
- and
- (d) a spring washer positioned in said inside recess of said nut to restrict axial movement of said screw.
