Description

Composite outer wall Technical Field The utility model relates to the technical field of outer walls, in particular to a composite outer wall. Background In the prefabricated composite outer wall heat insulating system, the connecting parts are key parts for connecting and fixing the outer facing, the heat insulating layer and the inner facing. The connecting piece widely used at present is mainly made of metal materials (such as stainless steel and aluminum alloy) or FRP (fiberglass reinforced plastics) materials, and is connected in a wet mode, namely, the connecting piece and the cement-based materials with inner and outer decorative surfaces are poured in factories, and connection is realized after the cement-based materials are cured and molded. For example, the prefabricated concrete sandwich heat-insulating external wall panel generally comprises a concrete inner leaf plate such as 200mm thick, a heat-insulating layer such as XPS plate 100mm thick, a concrete outer leaf plate such as 60mm thick, a connector system and the like, wherein the connectors are mainly divided into stainless steel connectors and FRP connectors, the stainless steel connectors mainly comprise truss type, sheet type and needle type connectors, the FRP connectors comprise rod-shaped FRP connectors, plate-type FRP connectors and the like, and the connectors are fixed in a pre-buried and post-poured concrete wet connection mode. The (ultra) high-performance concrete light steel joist outer wall is compounded with the light steel joist through an outer facing to form a facing framework. When integrating insulation boards with finished interior facings, the interior facings are typically attached to the light gauge steel with long self-tapping screws. However, the long self-tapping screw material has the problems of high heat conductivity coefficient, easiness in forming a thermal bridge effect, increased building energy consumption, easiness in aging, poor rigidity, easiness in deformation and the like in a complex damp-heat environment, and is not suitable for ultra-low energy consumption, near zero energy consumption and zero energy consumption buildings. Disclosure of Invention Aiming at the prior art, the utility model provides a composite outer wall, which is connected by adopting a heat-insulating bridge connecting piece, and can solve the problems of obvious heat-insulating bridge effect, poor durability, poor rigidity and complex construction of the prefabricated composite outer wall connecting piece in a factory. The utility model provides a composite outer wall, which comprises a plurality of FRP connecting pieces, wherein each FRP connecting piece comprises a main FRP component and a secondary FRP component, the main FRP component and the secondary FRP component are both arranged into a groove structure, the first end of the main FRP component is fixedly connected with the secondary FRP component in a penetrating way, and the web plate of the secondary FRP component forms a closed end face of the first end of the main FRP component. Preferably, the two side wing plates of the secondary FRP component are fixedly connected with the two side wing plates of the main FRP component through a plurality of rivets respectively. Preferably, the utility model also comprises a light steel keel, and a wing plate at one side of the second end of the main FRP component is fixedly connected with the light steel keel through a connecting bolt. Preferably, the utility model also comprises an outer blade plate, and the outer blade plate is poured on one side of the light steel keel, which is far away from the secondary FRP component. Preferably, the heat insulation board is further arranged on the FRP connecting pieces. Preferably, the novel fiber reinforced plastic composite material further comprises an inner decorative panel, wherein the inner decorative panel is fixedly connected with the web plate of the secondary FRP component through self-tapping screws. Compared with the prior art, the high-performance FRP material has the beneficial effects that 1, the heat-insulating performance is excellent, the multistage heat-insulating bridge design (main FRP component and secondary FRP component) is adopted to replace a metal connector, the heat-insulating bridge effect can be reduced by 70%, 2, the durability is enhanced, the rigidity is improved, the durability of the high-performance FRP material is improved by 30% compared with that of a common metal connector, the rigidity is improved by more than 90%, 3, the construction is convenient, the FRP connector and the light steel joist are integrally installed, the internal facing pouring and maintenance procedures are omitted, the installation process of the connectors is dry connection, the installation steps are reduced, the installation is convenient, the production period is shortened by 30%, 4, the economical efficiency is that the service life can reach 50 years, and the total life cyc
