CONCRETE DENSE COLUMN GYPSUM COMPOSITE EXTERNAL WALL BOARD

摘要

A concrete dense column gypsum composite no-cold-bridge external wall board,
composing of high-strength gypsum, concrete, fly ash, waterproofing agent,
fiber
reinforcement, A connection bar, B connection bar, light insulation material,
plate with
reserving cavity for concrete and the concrete pouring on site in the cavity.
From
inside to outside in order the wall board comprises: high-strength gypsum
layer, light
insulation material layer, high-strength gypsum concrete-reserving cavity
layer and
the reinforcement concrete dense column poured in the reserving cavity on
site. All
the layers are connected by the uniformly distributed A connection bars and B
connection bars, which bars are divided into 4-10 vertical parts at both ends,
and
there are fiber reinforcements in the high-strength gypsum layer and the
reserving
cavity layer. This wallboard provides the functions of enclosure, weight-
loading,
sound-proofing, insulation, seismic-protection and fire-proofing, and is
applicable for
the industrialization of the living house production method.
