Fabricated light steel composite outer wall plate and preparation method thereof

Abstract

The invention discloses a fabricated light steel composite outer wall plate comprising a first composite outer wall plate main body, a second composite outer wall plate main body and main body steel. The first composite outer wall plate main body and the second composite outer wall plate main body are both arranged on the same side of the main body steel and internally provided with vertical keels and heat preservation layers. The heat preservation layers are located on the inner sides of the vertical keels. The fabricated light steel composite outer wall plate has the characteristics of light weight, high strength, personalization, integration and the like, the building overall performance can be greatly improved, the building prefabricating rate and the industrialization degree can be increased, the unit weight is small so that the system can be perfectly matched with a steel structure prefabricated building, the main body load can be effectively reduced when the fabricated light steel composite outer wall plate and a cast-in-situ frame are combined, the using quantity of cement and steel bars / steel components are decreased accordingly, and secondary decoration work of the outer wall and the inner wall surface is also omitted.

Description

technical field [0001] The invention relates to the technical field of composite exterior wall panels, in particular to an assembled light steel composite exterior wall panel and a preparation method thereof. Background technique [0002] Today, when building industrialization is increasingly advocated, the disadvantages of traditional building construction techniques are becoming more and more obvious. For example, dry-hanging stone external walls, according to the procedure, first build the walls, then install light steel keels, then fill insulation materials such as rock wool, then hang stones, and install windows. The quality of stone glue joints cannot be guaranteed, and there will be plate color difference and glue joint aging in the later stage; similarly, the exterior wall of veneer bricks will also encounter the risk of brick falling off, and the exterior wall of paint will be exposed to the wind, rain and sun. The coating is cracked and weathered, so the integrate...

Problems solved by technology

For example, dry-hanging stone external walls, according to the procedure, first build the wall, then install light steel keels, then fill with thermal insulation materials such as rock wool, then hang stones, and install windows. The quality of stone glue joints cannot be guaranteed, and there will be plate color difference and glue seam aging in the later stage; similarly, the exterior wall of veneer bricks will also encounter the risk of brick falling off, and the exterior wall of paint will be exposed to the wind, rain and sun. The coating is cracked and weathered, so the integrated exterior wall system is the trend and development direction

[0003] At present, in the field of construction industrialization, the external protection system of the frame structure is mainly concrete external wall panels, especially in East China, where concrete sandwich external wall panels are widely used, but the inner and outer leaf concrete layer walls are self-heavy (300kg / ㎡ Above), the steel content of the main structure increases, and it is too heavy than the curtain wall, which also has certain safety problems; in addition, there are weak links such as single external decoration effect and cold bridge condensation
