PCF board mounting structure
The invention relates to building construction, in particular to a PCF plate mounting structure.
With the increase of transformation and upgrading speed of the building industry, prefabricated buildings are more and more favored by people due to the characteristics of production standardization, installation mechanization, construction management standardization, construction process integration and the like. The PCF external wall panel (namely the prefabricated external wall panel) is a prefabricated component in a composite external wall template form with heat insulation and external wall facing bricks, and is prefabricated by a factory. After the shear wall is installed on a construction site, the shear wall is connected and fixed with a lining cast-in-place concrete structure template system in a pulling mode to form a complete shear wall system, and then the cast-in-place shear wall structure is constructed to form an outer surface shear wall maintenance system of the residential building.
On one hand, the traditional PCF plate fixing and adjusting in-place method is that L-shaped angle irons are installed on the inner side of a PCF component and are respectively connected with a floor slab and a heat insulation plate. The operation is inconvenient because the inner side is provided with the shear wall steel bars; in addition, the thermal insulation plate has elasticity, and the PCF plate can only be adjusted inwards and cannot be adjusted outwards to be in place.
On the other hand, in the connection of the PCF board and the outer wall, the traditional method is a method of combining a special connecting piece (a hafen connecting piece, an FRP connecting piece and the like) and a split bolt, when the PCF board is hoisted in the construction process, the shear wall steel bars are easy to collide with the special connecting piece, so that the safety performance of the PCF board is influenced, and in addition, the later-stage plugging screw holes have hidden water leakage quality hazards.
