Such scheme can more preferably:
Described bed die comprises bed die concrete foundation and the bed die steel plate on it, and described arc surface is arranged in the two ends of described bed die steel plate.Described arc surface is 5cm with the stand out of corresponding bed die concrete foundation end.
The web of described internal mold is provided with many groups for finely tuning the narrow strip template of web height, and the width of described narrow strip template is at 1 ~ 2cm; Require the usage quantity of adjustment internal mold increase and decrease joint narrow strip template during construction according to design horizontal wall inscription, make the horizontal wall inscription of internal mold top plate consistent with engineering design.
The utility model changes traditional box girder formwork manufacture method, is removed by the circular arc portion of prefabricated case beam side form, extends the height of side form web templates, to meet adjusting tank beam horizontal wall inscription to the requirement of form height.Together with the template construct at prefabricated case beam base plate and bottom circular arc two sizes, all changeless position of shape.Bed die concrete foundation width is equivalent or slightly larger than bed die straight portion, but is less than the width of base plate circular arc.Stand out between base plate circular arc and bed die concrete foundation (general one-sided can have about 5cm), general box girder web height slope than being 4:1, the scope of side form adjustment web height reaches 20cm.Box girder web top width is about about 2 meters, and therefore case beam horizontal wall inscription regulates mobility scale in the amplitude of 0% ~ ± 10%, can meet the excursion of most road horizontal wall inscription.And prefabricated case beam base plate and bottom circular sliding slopes one, avoid circular arc and bed die seam bottom conventional template side form and easily occur seam imprecision, produce the phenomenon of spillage.
