The invention relates to the technical field of
building construction, and discloses a cold-bridge-prevention
thermal insulation construction method for a wall body of a
refrigeration house, which comprises the following steps of: pre-treating a wall surface before construction, then directly spraying
cyanogen condensate on the treated wall surface on the cleaned wall surface, and designing and installing wood and T-shaped piles in order to enable the
cyanogen condensate to fully permeate into a base layer. Then, a steel row gun is used for installing the wall surface,
polyurethane foaming spraying construction is conducted after installation, the thickness of foam sprayed in a single layer is conducted for the first time, an anti-crack
fiber net is hung and a transverse
cork wood
keel is installed when the foam is sprayed to be half of the design thickness, a
polyurethane heat preservation layer is sprayed to be the design thickness, and after
polyurethane spraying foaming finishing is completed, the position of a door and
window opening is located at the position of a door and
window opening; and wall
surface heat preservation and color steel plate construction are completed. By the adoption of the double-layer spraying
cyanogen condensation waterproof vapor-proof layer, effective
moisture prevention and
air tightness are achieved, the effect of greatly reducing
moisture permeation in the
refrigeration house is achieved, formation of a cold bridge is avoided, and the energy-saving effect of the
refrigeration house is improved.
