overviewRein
Since the reform and opening up, with
the national economy's rapid and sustained
development of a reinforced concrete
structure built, reinforced with the development
of technology has been great.
Therefore, to promote the use of advanced
technology
reinforced

pace
of
construction, improve
labor productivity, reduce costs, and is of great
significance.
Reinforced

technologies
can
be
divided
into
two
broad
categories linking welding machinery
and steel. There are six types of welding steel
welding methods, and some apply to the
prefabricated plant, and some apply to the
construction site, some of both apply.
There are three types of machinery commonly
used reinforcement linking method
primarily applicable to the construction site.
