Prefabricated outer wall and PCF plate fixed connection structure and construction method thereof

Abstract

The invention discloses a prefabricated outer wall and PCF plate fixed connection structure and a construction method thereof. The prefabricated outer wall and PCF plate fixed connection structure comprises a PCF plate, an outer wall plate, a connecting steel plate, a plurality of circular ring heightening gaskets, a bolt I and a bolt II, one part of the connecting steel plate is attached to the inner side of the outer wall plate, and the other part of the connecting steel plate is attached to the inner side of the PCF plate, a bolt sleeve I and a bolt sleeve II corresponding to the connectingsteel plate are pre-embedded in the PCF plate and the outer wall plate respectively, a through hole I and a through hole II are formed in the connecting steel plate, the bolt I penetrates through thethrough hole I and is in threaded connection with the interior of the bolt sleeve I, the bolt II penetrates through the through hole II and is in threaded connection with the interior of the bolt sleeve, and the circular ring heightening gaskets are arranged between the bolt I and the connecting steel plate and between the bolt II and the connecting steel plate correspondingly. According to the structure, a worker does not need to stand on a scaffold to reinforce the outer side of the PCF plate, reinforcement can be completed only in a floor, safety is guaranteed, penetrating holes do not need to be formed, and the vertical flatness of the PCF plate can be adjusted by adjusting the number of the circular ring heightening gaskets.

Description

technical field [0001] The invention belongs to the field of prefabricated building construction, in particular to a fixed connection structure between a prefabricated outer wall and a PCF board and a construction method thereof. Background technique [0002] With the advancement of construction technology, industrialized buildings have gradually been widely used, and prefabricated houses have become a development trend. The prefabricated exterior wall is an indispensable component in the prefabricated project. It has the advantages of shortening the construction period, simple construction, safety and reliability during construction. [0003] Prefabricated exterior walls commonly used on construction sites are generally divided into sandwich exterior walls and PCF panels. PCF panels are generally composed of outer shale and insulation layers, and sandwich exterior walls are composed of inner shale, outer shale, and insulation layers. PCF panels are used at the corners, and...
