Description
Technical field
The invention belongs to prefabricated components fields, and in particular to a kind of prefabricated components inner core template is anti-to float device and its installation side
Method provides the method for resisting buoyancy to prefabricated components inner core template, is primarily adapted for use in various internal core mold plates and generates buoyancy
Armored concrete box structural elements in.
Background technique
In recent years, with the development of national boosting assembled architecture energetically, the development of prefabricated components is very rapid, especially
Heavy civil component Industrialized processing technique tends to be mature.For the box-shaped precasts structure such as Reinforced Concrete box beam, piping lane
Part, the buoyancy that internal core mold plate generates in concreting process can not be ignored, generally considerably beyond the self weight of inner core die, institute
It is the emphasis that should consider in construction with the control that internal core mold plate floats, therefore being arranged that the anti-floating device of inner core template extremely has must
It wants, and Development of Novel is prefabricated（Box）The anti-floating device of component inner core template has wide application space.
However at present in floating device control Form floating anti-using similar traditional inner core template, within core mold plate top
The high-strength concrete cushion block of placement（Force transfer bracket）Concrete buoyancy is passed into top float Structure, by increase thereon weight come
External force is provided and achievees the purpose that anti-floating, since contact area is small between concrete pad and inner core die panel, is easy to cause inner core
Mould local deformation is excessive；And the power in each concrete pad more difficult to control keeps uniformly, it is inclined existing will lead to inner core die
As effectively being controlled to can not float to inner core die.On the other hand, the anti-floating device of existing inner core template constructs mostly
It is complicated and member exterior, subsequent dismounting wasting manpower and material resources need to be placed outside；Compare and is difficult in armored concrete box girder with variable cross section, face
It is easy to use in the more closely knit component of slab muscle.Furthermore it generally needs to apply by Large Hydraulic Equipment when float Structure is arranged
Work complex process and costly.The presence of these problems restricts the development and application of large volume box-shaped precast component.
Summary of the invention
Aiming at the problems existing in the prior art, the present invention provides a kind of anti-floating device of prefabricated components inner core template and its peace
