Claims

[Scope of Claim for Utility Model Registration] (1) Multiple support pipes erected on concrete, etc., and an upper beam pipe and a lower beam pipe installed between these support pipes by inserting them into joint pipes formed integrally with the support pipes. It consists of a beam tube and a plurality of vertical tubes that are inserted into connecting holes provided in both beam tubes and installed upright.
The upper beam tube and the lower beam tube each include an engaging member which is spring-biased by a spring member and protrudes from a first hole formed in the end tube wall thereof, and the engaging member is spring-biased by a spring member. The vertical tube includes a second hole that overlaps the first hole when the upper beam tube and the lower beam tube are inserted and is engaged by the engaging member,
a small diameter portion having a polygonal cross section and fitting into the vertical pipe;
1. A fence comprising a connecting member having a large diameter part having the same diameter or less than the outer diameter of a vertical pipe, and a variable diameter part whose diameter gradually increases from the small diameter part to the large diameter part. (2) The first hole is formed in the joint pipe, the engaging member is spring-biased by the spring member so as to be able to come out and go out of the first hole, and protrudes from the joint pipe, and the second hole is provided in the joint pipe. The fence according to claim 1 of the utility model registration, characterized in that it is provided in the upper beam tube and the lower beam tube.
