Abstract

The invention relates to the technical field of building partition joints, and discloses an assembly-type sandwiched heat-preservation multi-ribbed composite outer wall plate partition joint device and a construction method. The device comprises inner filler, outer filler and at least two assembly-type sandwiched heat-preservation multi-ribbed composite outer wall plates; the inner filler is fixed on the inner side of a partition joint formed between every two adjacent assembly-type sandwiched heat-preservation multi-ribbed composite outer wall plates; the outer filler is fixed on the outer side of the partition joint formed between every two adjacent assembly-type sandwiched heat-preservation multi-ribbed composite outer wall plates. Compared with a partition joint processed through an existing technology, the constructed partition joint has the advantages that the outer heat preservation performance is improved by 2% to 5%, the energy consumption rate is decreased by 5%-10%, the heat transfer coefficient is decreased by 6% to 8%, and the bonding strength reaches the building bonding strength index required by national regulation; the phenomenon that a heat preservation layer and a protection layer are subjected to extruding destruction caused by stress at high and low temperature can be prevented from occurring, the heat working performance of the outer wall plates is improved, and the phenomenon that the outer wall plates generate the cold or heat bridge effect is avoided.

Description

technical field

[0001] The invention relates to the technical field of building separation joints, and relates to a separation joint device and a construction method of an assembled sandwich thermal insulation dense-ribbed composite outer wall board separation joint. Background technique

[0002] In order to meet the energy-saving requirements of residential buildings in severe cold climates in Northwest China, an insulation layer and a protective layer were sequentially added to the outside of the original dense-ribbed composite wall, and prefabricated sandwich-insulated dense-ribbed composite wall panels in the form of a "sandwich" were prefabricated in the factory. The wall panel is a new type of composite wall panel that integrates earthquake resistance, energy saving and assembly. After the wall panel is transported to the site for hoisting and connection, two assembled sandwich insulation dense rib composite exterior wall panels are adjacent horizontally and vertically....
