Second short flanging 12 of the opening portion 13 of square frame far from the first of rectangular frame the short flanging 11 and rectangular frame, obtains
Pedestal；In order to be closed opening portion 13, the intensity and toughness of rectangular frame entirety are improved, it can will be after the both ends bending of the first reinforcing bar
Welded together by way of melting welding.
Step 2: the first cover board 2 of preparation, it is the screw-thread steel of 20mm that the second reinforcing bar, which selects diameter, is flattened by punching press
The first cover board 2 is formed, the 2 one end punching press of the first cover board is shaped to the first hook for being used to be articulated in the first short flanging 11, the
One cover board, 2 other end is stamped and formed out bayonet；It, can be whole by 2 punching press of the first cover board in order to be bonded the first cover board 2 preferably with steel pipe
Shape makes the first cover board 2 have the radian coincideing with steel tube surface.
Step 3: the first hook is mounted on the first short flanging 11 by the first cover board 2 of installation, is hung by punching press by first
Hook shaping circlewise, is hinged on 2 one end of the first cover board on the first short flanging 11.
Step 4: the second cover board 3 of preparation, selecting diameter is the plain bar of 10mm, and one end is flattened shape by punching press
At the second cover board 3, the thread rod part 31 of the second cover board 3 is formed in its other end threading, by the second cover board 3 far from screw thread
One end punching press of bar portion 31 is shaped to the second hook for being articulated in the second short flanging 12.
Step 5: the second hook is mounted on the second short flanging 12 by the second cover board 3 of installation, is hung by punching press by second
Hook shaping circlewise, is hinged on the second cover board 3 on second short flanging 12 far from one end of thread rod part 31.
Step 6: locking nut 4 is mounted on thread rod part 31 by installation locking nut 4, completes fastener unit 100
Production；Step 7: fastener unit 100 assembles, and two fastener units 100 are stacked in cross, the base of two fastener units 100
Seat 1 mutually across and be welded to connect.
In aforementioned production method, after the completion of preparing pedestal 1, first two pedestals 1 can also be welded, then prepare respectively
One cover board 2 and the second cover board 3, then install the first cover board 2 and the second cover board 3 on each pedestal 1.It should be appreciated that above-mentioned life
The sequence of each step in production method can appropriate adjustment repeat no more here.
Finally, it is stated that preferred embodiment above is only used to illustrate the technical scheme of the present invention and not to limit it, although logical
It crosses above preferred embodiment the present invention is described in detail, however, those skilled in the art should understand that, can be
Various changes are made to it in form and in details, without departing from claims of the present invention limited range.
