Examine, occur underplate concrete leakiness leachy defect during construction if not vibrated fully to concrete, influence box beam into
Quality after type, it is impossible to meet construction demand.
The content of the invention
The invention discloses a kind of observation window construction for the cast of box girder inner formwork lower concrete, efficiently solve prefabricated
The bottom parts construction leachy problem of concrete leakiness in highway box girder construction.
To achieve these goals, the technical scheme of present invention offer is：One kind is poured for box girder inner formwork lower concrete
The observation window construction of note, including backform 1, side form 2 and bed die 3, it is characterised in that：Movable observing is provided with the bed die 3
Window.
In observation window construction for the cast of box girder inner formwork lower concrete disclosed by the invention, the movable observing window
Structure is that a window is opened up on bed die 3, and shape identical observation window cover 42, the observation therewith are provided with the window
One end of window cover 42 is flexibly connected with bed die 3, and the other end is connected with the bolt 43 being fixed on bed die 3.
In observation window construction for the cast of box girder inner formwork lower concrete disclosed by the invention, the window is shaped as
Rectangle, circle, ellipse.
In observation window construction for the cast of box girder inner formwork lower concrete disclosed by the invention, the side of the flexible connection
Formula is to be hinged, pin connection and lock are connected.
Compared with prior art, the invention has the advantages that：1st, bed die increased observation window, can be in observation window
Vibrated with vibrating head, the closely knit situation of observable underplate concrete, excessive gas can be excluded by observation window in concrete.
2nd, observation window cover by hinge be welded on bed die can free-open-close, the other end can be with fixing lock by bolt
Extremely, it is easy to operate.
3rd, the present invention allows construction molding of prefabricated case beam base plate, it is to avoid because vibrating not enough concrete leakiness and
Carry out secondary construction repairing.
4th, in practice of construction, easy construction improves prefabricated case beam bottom parts construction effect to the present invention.
