Building unit combined type heat preservation and decoration integrated outer wall hanging plate and mounting method

Abstract

The invention discloses a building unit combined type heat preservation and decoration integrated outer wall hanging plate and a mounting method. The outer wall hanging plate is of a layered compositestructure and sequentially comprises an inner side heat preservation layer, a reinforced concrete frame, a fireproof heat preservation layer and a decoration plate layer from inside to outside, the reinforced concrete frame is formed by connecting reinforced concrete frame ribs which are located on the four sides and inside the reinforced concrete frame and distributed in the longitudinal direction and the transverse direction, a heat preservation filling layer is embedded in the reinforced concrete frame, rectangular truss reinforcement cages are arranged in the reinforced concrete frame ribs, a plurality of dry hanging keels which are arranged in the longitudinal direction and are horizontally arranged are arranged in the fireproof heat preservation layer, each dry hanging keel is fixedto the outer side of the reinforced concrete frame through embedded bolts embedded in longitudinal reinforced concrete frame ribs, the space between every two adjacent dry hanging keels is filled with a fireproof heat preservation material, the decoration plate layer is formed by splicing a plurality of decoration plates, and the decoration plates are connected with the dry hanging keels adjacentto the inner side of the decoration plates together in a dry hanging mode through dry hanging connecting pieces.

Description

technical field [0001] The invention relates to the technical field of building exterior wall heat preservation and exterior wall decoration, in particular to a unit-combined heat preservation and decoration integrated exterior wall hanging board. Background technique [0002] At present, building energy-saving technology has had unprecedented development and progress. The thermal insulation and decoration of building envelopes have become the focus of building energy conservation research. Building internal thermal insulation technology is gradually being replaced by external wall thermal insulation technology, which is gradually being promoted and applied. [0003] Among them, the most commonly used method is to paste the insulation board on the outer wall surface with adhesive mortar, and apply a thin layer of polymer anti-cracking mortar on the outside of the insulation board as the decorative board layer, but the durability is insufficient, and the life span is at most ...

AI Technical Summary

Problems solved by technology

However, it was found during use that there are still some problems with this exterior wall panel: (1) Because the exterior wall thermal insulation system is a thermal insulation system installed on the surface of the building exterior wall, the environmental conditions change complicatedly, and the outermost thin layer aggregates The anti-cracking mortar is exposed to wind, sun and rain for a long time, and after several years or more than ten years, it is very easy to crack and fall off. At this time, the insulation finish layer cracks and falls off, and the insulation layer is exposed. It is not waterproof, and it is even more unsafe. ; Frequent maintenance or replacement of the external wall insulation system is required; (2) The thermal insulation performance of the joints between the upper, lower, left, and right sides and the adjacent external wall siding is not good, and it is easy to form a cold bridge, and it has no fire protection function

During the construction process, metal keels are first installed on the surface of the outer wall, and then thermal insulation materials are placed on the metal keel to hang stones, ceramic plates or metal plates. The construction is complicated, the installation speed is slow, the construction period is long, the construction cost is high, and it is difficult to guarantee the quality requirements.
