Field of Technology
[0001] The present invention relates to a connection clamp of building formwork in the field
of technology for architectural construction.
Background Art
[0002] The aluminum formworks currently available on construction market are normally assembled
and connected through iron pins and iron tabs in a perforated manner; the iron pins
are inserted into the corresponding holes made on the sides of both aluminum formworks;
the iron tab is inserted into the iron pin slot, hammered down and bent to prevent
its drop that may cause the iron pin to get loose. This connection method has shortcomings
in practice: Since the iron tab is bent during installation, it must be straightened
and knocked off during the removal to loosen the iron pin, which brings about a relatively
low disassembly efficiency; moreover, the strong hammer force applied to iron tab
may often cause the iron tab to shoot out at high rate, and such flying iron pins
may cause personal injury from time to time, which poses a serious potential safety
hazard; secondly, since the iron tab is thin, it may get out of service when frequently
hammered, needing to be replaced after several operations; furthermore, iron tab is
as small in size as iron pin, it's easy to lose, which may lead to the increase in
construction cost.
