Prefabricated sandwiched thermal-insulation wallboard with novel connectors

Abstract

The invention discloses a prefabricated sandwiched thermal-insulation wallboard with novel connectors. The prefabricated sandwiched thermal-insulation wallboard comprises a prefabricated wallboard internal wall, a sandwiched thermal-insulation layer and a prefabricated wallboard external wall from inside to outside, stress reinforcing steel bars are arranged in each of the prefabricated wallboard internal wall and the prefabricated wallboard external wall, and rubber airtight strips are arranged at the upper and lower ends of the sandwiched thermal-insulation layer; the latticed fiber connectors are vertically arranged between the prefabricated wallboard internal wall and the prefabricated wallboard external wall in a continuous manner or at intervals, and two sides of each latticed fiber connector are respectively embedded into the prefabricated wallboard internal wall and the prefabricated wallboard external wall; an internal decoration layer attaches to the surface of the prefabricated wallboard internal wall, and an external decoration layer attaches to the surface of the prefabricated wallboard external wall. By the arrangement, the prefabricated sandwiched thermal-insulation wallboard has the advantages that the heat bridge effect in the prefabricated sandwiched thermal-insulation wallboard is avoided effectively, and the wallboard is good in thermal-insulation and fireproof effects, capable of being fast mounted on a construction site and applicable to assembling fields such as public and civil buildings.

Description

technical field [0001] The invention relates to a prefabricated sandwich insulation wallboard with a novel connector, which is mainly (but not exclusively) used in the field of prefabricated assembled buildings. Background technique [0002] With the promotion of prefabricated technology, the proportion of prefabricated components in buildings has gradually increased, especially the prefabricated external wall panels used for enclosure structures. At present, the connectors in the prefabricated sandwich insulation wall panels are mainly metal connectors, which can not solve the problem of thermal bridge properly, and the durability of metal is also a factor that needs to be considered, and the installation process on site is more complicated. , The resulting increase in processing and installation costs of the wall panels is not conducive to the cost control of the project. [0003] Therefore, how to effectively solve the problem of thermal bridges with prefabricated walls,...
