Compound heat preservation die plate and concrete one-off construction outer wall heat preservation system and construction technology thereof

Abstract

The invention discloses a compound heat preservation die plate and a concrete one-off construction outer wall heat preservation system and a construction technology thereof. The invention is characterized in that the compound heat preservation die plate is used for replacing simultaneous construction of the die plate and concrete pouring, so that a heat preservation layer and a building mainbody can be completed together; the compound heat preservation die plate can both act as a heat preservation plate and a die plate, thus saving outer wall die plates in large quantities, greatly shorteningconstruction period and cost, fundamentally resolving the question of connection soundness between the heat preservation layer and the building mainbody, addressing the question of flatness and verticality of the heat preservation layer and ensuring construction quality.

Description

Technical field: [0001] The invention relates to the technical field of building exterior wall heat preservation, in particular to a composite heat preservation formwork and concrete one-time construction exterior wall heat preservation system and construction technology, which are used for heat preservation of building exterior walls. Background technique: [0002] With the rapid development of the economy and the rapid growth of energy demand, the form of energy is very severe. "Energy saving priority" has become a strategic decision for energy development. Therefore, the country vigorously promotes energy-saving technologies in various fields, and implements mandatory building energy-saving standards in the construction field. The existing external wall insulation technologies mainly include: polystyrene board (EPS, XPS) insulation material series, polyurethane insulation series, slurry insulation material (polystyrene powder particles, insulation mortar, phase change mat...

AI Technical Summary

Problems solved by technology

[0007] The present invention mainly solves the problem that the bond between the thermal insulation layer and the concrete in the existing panel-type external adhesive thermal insulation technology is not firm, the combination of on-site polyurethane spraying is firm, but the thickness of the thermal insulation layer is difficult to control, the construction period is long, the process is complicated, the efficiency is low, the construction quality is difficult to control, and the external Problems such as limited finish layer and high cost
