Description
Technical field
The present invention relates to a kind of architectural shape, a kind of superimposed sheet strengthening two-way transmission force property.
Background technology
Superimposed sheet is an important composition component in prefabricated assembled concrete structure, has the most obtained relatively broad
Application.Owing to by producing, transport and the aspect such as lifting being limited, in building course, the superstructure in single room is often
By polylith superimposed sheet assembling combination.Piece between superimposed sheet side need to use difference because using different designs principle
Construction way.
Current existing all kinds of superimposed sheets are that the integral cover after ensureing assembly forms two-way power transmission mechanism, need to use and spell
Arranging the assembled way of cast-in-place band at seam, this results in site operation and adds that to install template, scaffold and assembling reinforcement etc. many
Road working procedure, and increase the amount of pouring of concrete, greatly reduce efficiency of construction.But the overlapping according to direct piece
Plate assembling process, then the superimposed sheet after assembly need to be designed by one-way slabs according to specification, which increases the steel using amount of integral cover,
Add cost.
Existing experimental study achievement shows, uses the superimposed sheet of direct piece mode, in the strip being perpendicular to piece direction
Still having certain bending rigidity, this bending rigidity can utilize in the design.But experimental study shows, vertically
The strip in piece direction vertical load reach capacity load about 20% time, it may occur that piece position is prefabricated and cast-in-place mixed
The breakoff phenomenon that solidifying soil faying face disengages, this destruction will greatly reduce the bending rigidity of direction strip, causes overall folded
Plywood cannot form good two-way power transmission mechanism.
