Abstract
The utility model provides a hollow mould for a concrete precast plate girder. The hollow mould is characterized in that a plurality of positioning hoops are longitudinally arranged on a rubber core mould; a charging valve is arranged at one end of the rubber core mould; and a plurality of hooks are arranged on the two sides of the positioning hoops. The hollow mould has the following beneficial effects that: the rubber core mould is arranged to replace the ordinary timber formwork in the construction process of precasting the concrete plate girder; and the hollow mould is easy and fast to operate, can be recycled and saves materials and cost.
Description
Technical field
The utility model relates to a kind of hollow mould of building engineering shuttering device, particularly a kind of concrete prefabricated plate-girder.
Background technology
In building engineering construction; During prefabricated large-scale concrete hollow slab girder, its hollow part adopts the normal wood template to add the method for chapelet usually, and the not only molding of this method, formwork erection, form removal are time-consuming; And mould material can not have enough to meet the need use; Cause the consumption of material big, speed of application is slow, and is extremely uneconomical.
Summary of the invention
A kind of concrete prefabricated plate-girder hollow mould that the utility model provides has overcome time-consuming, the high material consumption of method that above-mentioned employing normal wood template adds chapelet, and speed of application is slow, extremely uneconomic problem.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is: a kind of concrete prefabricated plate-girder hollow mould, rubber mandrel vertically be provided with the multiple tracks spacer ferrule.
One end of rubber mandrel is provided with charging valve.
The both sides of spacer ferrule are provided with many hooks.
The cross section of said rubber mandrel is oval.
A kind of concrete prefabricated plate-girder hollow mould that the utility model provides through in precast concrete plate-girder work progress, rubber mandrel being set, substitutes common plank sheathing, and simple and quick, mould can have enough to meet the need use, and economical with materials is saved cost.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Fig. 1 is the concrete prefabricated plate-girder formwork erection of a utility model side view;
Fig. 2 is that the A-A of Fig. 1 is to view;
Fig. 3 is the structure chart of the utility model device;
Fig. 4 is that the B-B of Fig. 3 is to view.
Wherein: 5, enclose Eurya plant, 6, the precast slab beam steel, 7-1, steel form, 7-2, side wall template, 8, tie rod.9, concrete floor.
The specific embodiment
As shown in Figure 4, a kind of concrete prefabricated plate-girder hollow mould, rubber mandrel 1 vertically be provided with multiple tracks spacer ferrule 2, an end of rubber mandrel 1 is provided with charging valve 3, the both sides of spacer ferrule 2 are provided with many hooks 4.
The cross section of rubber mandrel 1 is oval, and the size of rubber mandrel 1 is confirmed by designing requirement.
Embodiment:
1) rubber mandrel 1 adopts the bilateral vulcanization adhesive plaster in processing factory, to make moulding according to design size, and bilateral vulcanization adhesive plaster breaking strength (N/25 mm): warp-wise is greater than 1000, and broadwise is greater than 800; Glue and cloth adhesion strength (N/25 mm): greater than 15.Rubber mandrel 1 is inflated to working pressure breaking strength (N/25 mm), is not more than 20% through the 8h pressure drop.
2) adopt 12 round steel in processing factory, to make spacer ferrule 2 according to design size (identical with cavity size), its upper and lower both sides hook 4 adopts the 8# iron wire to process.
3) treat the concrete prefabricated board beam steel set up finish after, spacer ferrule 2 is inserted in manual work, spacing 0.5～0.8m, its hook 4 hangs firmly with the reinforcing bar of colligation.
4) before rubber mandrel 1 used, the interview inflation on ground earlier was with the intact situation of inspection rubber mandrel 1.After being coated with full releasing agent around the intact rubber mandrel 1, penetrate in the steel reinforcement cage through the rope traction.
5) rubber is opened charging valve 3 after core 1 is in place, with the air compressor machine inflation, must not note superpressure during rubber mandrel 1 inflation, is not more than 0.03Ma.
6) casting concrete is built and must be used the high frequency tamping rod to vibrate simultaneously from both sides when vibrating in the process, preventing rubber mandrel 1 partial left dextroposition, and vibrates and can not touch rubber mandrel 1, in order to avoid damage rubber mandrel 1.
7) treat that concrete initial set reaches the form removal condition after, open charging valve 3 gas discharged, rubber mandrel 1 just can come off voluntarily, local not separated part is taked the method demoulding of artificial treatment, and then pulls out steel reinforcement cage through rope.
