Description

Assembled concrete presss from both sides core heat preservation and decorates integrative wallboard

Technical Field

The utility model relates to a building material field especially relates to an assembled concrete presss from both sides core heat preservation and decorates integrative wallboard.

Background

The prefabricated concrete sandwich heat-insulating external wall panel is an important prefabricated component integrating the functions of bearing, enclosure, heat insulation, water resistance, fire resistance and the like. The connecting piece is a key part for connecting the inner leaf concrete wallboard and the outer leaf concrete wallboard of the sandwich heat-insulation wall body and the heat-insulation plate and is also a key part for resisting shearing force between layers. At present, two types of commonly used matched type external sandwich wall panels in China are mainly provided, the difference is mainly the difference of the forms of connectors, the first type is a non-composite type sandwich wall panel which is connected by a connector with a glass fiber rib vertically inserted and widely adopted in the world, the temperature stress is easy to eliminate, the stress behaviors of two concrete plates of an inner leaf and an outer leaf are not interfered with each other, and the load is completely born by the concrete plate of the inner leaf; the second type is a composite sandwich wallboard connected by a truss connector made of reinforcing steel bars or composite material ribs, and has the advantages of better stress performance and common stress of the inner leaf concrete slab and the outer leaf concrete slab.

However, the non-composite sandwich wall panel adopting the non-composite connection has the problem of poor stress performance, and the connector is vertically inserted to cause the waste of rigidity, so that the number of required connectors is more, and the overall cost is increased; the composite sandwich wallboard adopting composite connection has the advantages that the composite effect is caused because the inner plate and the outer plate are completely connected by the oblique connectors, the temperature stress difference is easily caused when the temperature difference exists between the inside and the outside, and metal connectors such as reinforcing steel bars have the advantages of high strength, low price and the like, but the heat conductivity coefficient of the material is large, the heat bridge effect exists, the heat insulation effect of the wall body is influenced, and the problem of local cracks of the wallboard easily occurs; and the corrosion resistance of the steel bars is poor, resulting in a low life span of the connector member. The existence of the problems seriously hinders the large-scale application of the fabricated precast concrete sandwich thermal insulation external wall panel in the market.
