Description
Technical Field
The invention relates to the technical field of building construction, in particular to a prefabricated externally hung wallboard system based on UHPC integrated silicon graphene sandwich heat preservation.
Background
In the external wall heat preservation construction, in order to avoid the safety risk that the external heat preservation board is directly paved on the inner side wall body to cause easy falling, a prefabricated sandwich heat preservation external wall board (PCTF) system is adopted in the field, the PCTF is hung on the inner side wall body, and reliable connection of the PCTF on the inner side wall body is improved. The PCFT consists of a precast concrete wallboard and an embedded heat-insulating board thereon, wherein the heat-insulating board is a foam board. One side of the embedded heat-insulating board is attached to the inner side wall body through the heat-insulating connecting piece to be hung for construction, so that the embedded heat-insulating board is positioned between the precast concrete wall board and the inner side wall body to form a sandwich heat-insulating structure. Because the precast concrete wallboard is made of conventional concrete, the thickness of the precast concrete wallboard is thicker (not less than 55 mm), the thickness of the embedded insulation board is generally 40-50mm, and the thickness of PCTF is too thick (more than 95 mm) and the weight is large, wherein when the thickness of PCTF single components is too thick and is arranged on an inner wall body, the whole thickness of the outer wall is too thick, the whole area of the inner wall body is influenced, and the construction cost is increased. When the weight of the PCTF monomer component is overlarge, the lifting difficulty and the lifting risk are increased, after the PCTF monomer component with overlarge weight is hung on an inner side wall body, the PCTF monomer component is acted by the gravity of the weight, when the PCTF monomer component is hung on the inner side wall body only through the heat preservation connecting piece, the heat preservation connecting piece is influenced by the influence of wind force on the PCTF monomer component due to the fact that the holding power of the heat preservation connecting piece is insufficient, such as the condition that the heat preservation connecting piece is embedded loose is caused by disturbance of the heat preservation connecting piece to a foam board in the transportation lifting process, and the influence of the heat preservation connecting piece on the reliability of the PCTF monomer component on the inner side wall body leads to the safety risk that the PCTF monomer component is deformed or falls off, and particularly the influence of wind force on the heavy wind weather is more serious. Therefore, how to reduce the engineering cost of external wall insulation, improve the reliable connection of the external wall panel hung on the inner wall body, and ensure the use safety becomes a technical problem to be solved in the field.
