Abstract
The utility model provides a simple umbrella type drawing internal mold for a prefabricated hollow plate beam, and belongs to the technical field of bridge engineering. The simple umbrella type drawing internal mold is characterized in that a square steel drawing rod is arranged in a center line of an internal mold face plate, the internal mold face plate is connected with the square steel drawing rod through umbrella type framework connecting rods, and the umbrella type framework connecting rods are matched with the internal mold face plate and the square steel drawing rod through hinge pins in a rotating mode. The simple umbrella type drawing internal mold has the advantages that the simple umbrella type drawing internal mold can be repeatedly used and is convenient to detach and install and accurate in positioning, plate beam engineering quality is improved, and engineering cost is reduced.
Description
Technical field
The utility model belongs to technical field of bridge engineering.
Background technology
At present, in bridge construction engineering, near generally will be at the construction field (site), carry out the construction of precast hollow plate-girder, conventional core mold all adopts inflated rubber core, its deficiency is that construction cost is high, inflated rubber core is fragile, and deflation time is wayward after using, in work progress, easily floating causes top plate thickness deficiency.
Summary of the invention
The purpose of this utility model is: a kind of precast hollow plate-girder Simple umbrella type pull internal mold is provided, and it is can be convenient to install, the precast hollow slab internal mold of accurate positioning.
The technical solution of the utility model is: on internal mold face plate center line, be provided with square steel pumping rod, internal mold panel is connected by umbellate form skeleton connecting rod with square steel pumping rod, and umbellate form skeleton connecting rod is rotatably assorted by bearing pin with internal mold panel and square steel pumping rod respectively.
The beneficial effects of the utility model are: have and reuse, be convenient to dismounting, the advantage of accurate positioning, has improved plate-girder workmanship, has reduced engineering cost.
Accompanying drawing explanation
Fig. 1 is that the utility model uses the main sectional view of state;
Fig. 2 is the main sectional view of the utility model contraction state;
Fig. 3 is that the utility model uses side view of the state.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in the figure, the 1st, square steel pumping rod, the 2nd, umbellate form skeleton connecting rod, the 3rd, internal mold panel, the 4th, bearing pin A, the 5th, bearing pin B.
Umbellate form pull internal mold supported design is a kind of non-statically determinate structrue, and internal mold panel (3) adopts strengthens gusset, and the vertical supporting of strengthening gusset adopts umbellate form skeleton connecting rod (2), is connected respectively with internal mold panel (3), square steel pumping rod (1).Connected mode is by bearing pin A(4) and bearing pin B(5) be connected and fixed,,, in the time that square steel pumping rod (1) moves on internal mold panel (3) center line, realize internal mold panel (3) and shrink and Zhi Li as fulcrum by two bearing pins.
Square steel pumping rod (1) is made of channel-section steel, reinforcement fabrication for umbellate form skeleton connecting rod (2), square steel pumping rod (1) is used bearing pin A(4 with umbellate form skeleton connecting rod (2)) and bearing pin B(5) be connected and fixed, realize main shaft and umbellate form skeleton interlock.
Install: this internal mold face plate center symmetry, when installation, according to umbrella, principle is put in support, and by pull umbellate form skeleton connecting rod, middle umbellate form skeleton supports outside internal mold panel, realizes internal mold panel Zhi Li.After this shuttering supporting puts in place, with the consistent size of hollow beam slab, fixed internal formwork is accurate.
Remove: when the complete stripping of concreting, drag the middle square steel pumping rod of internal mold by electric winch, the reach of square steel pumping rod drives internal mold to shrink, and realizes internal mold and concrete and departs from.
