The beneficial effect of the utility model prefabricated box girder inner formwork anti-floating system is, by the support body screw rod that is connected, internal mold and outside is connected to form one, thoroughly to solve internal mold On The Floating.
Preferably, support body comprises: anti-floating crossbeam and the template supporting leg being connected with anti-floating crossbeam two ends respectively, and internal mold is connected with anti-floating crossbeam by connecting screw rod, and template supporting leg is connected with external mold.
Preferably, anti-floating crossbeam comprises: the channel-section steel of relatively putting, affixed by junction steel plate between the channel-section steel of relatively putting, template supporting leg is connected in the two ends of channel-section steel.
Preferably, offer screw hole on junction steel plate, connecting screw rod is arranged between the channel-section steel of relatively putting by screw hole.
Preferably, connecting screw rod is bidirectional modulation screw rod, is arranged with PVC sleeve pipe on connecting screw rod.
Brief description of the drawings
Fig. 1 is the overall structure schematic diagram of the utility model prefabricated box girder inner formwork anti-floating system;
Fig. 2 is the plan structure schematic diagram of Fig. 1;
Fig. 3 is the sectional structure schematic diagram of side, a-quadrant in Fig. 1.
Detailed description of the invention
For the benefit of the understanding to structure of the present utility model, describes below in conjunction with drawings and Examples.
With reference to Fig. 1, it is the overall structure schematic diagram of the utility model prefabricated box girder inner formwork anti-floating system.As shown in Figure 1, the utility model provides a kind of prefabricated box girder inner formwork anti-floating system, comprising: the internal mold 1 of prefabricated case beam and external mold 2, and internal mold 1 is connected with external mold 2 by a support body 3, and internal mold 1 is fixedly connected with support body 3 by a connecting screw rod 4.
In the present embodiment, support body 1 specifically comprises: anti-floating crossbeam 32 and the template supporting leg 31 being connected with anti-floating crossbeam 32 two ends respectively, and internal mold 1 is connected with anti-floating crossbeam 32 by connecting screw rod 4, and template supporting leg 31 is connected with external mold 2.
With reference to Fig. 2, it is the plan structure schematic diagram of Fig. 1.As shown in Figure 2, anti-floating crossbeam 32 comprises: the channel-section steel 320 of relatively putting, affixed by junction steel plate 322 between the channel-section steel 320 of relatively putting, template supporting leg 31 is connected in the two ends of channel-section steel 320.
With reference to Fig. 3, it is the sectional structure schematic diagram of side, a-quadrant in Fig. 1.Shown in Fig. 2 and Fig. 3, on junction steel plate 322, offer screw hole 324, connecting screw rod 4 is arranged between the channel-section steel 320 of relatively putting by screw hole 324.Connecting screw rod 4 is bidirectional modulation screw rod, is arranged with PVC sleeve pipe 5 on connecting screw rod 4.
Have after said structure feature, just can carry out according to the following steps field conduct:
First, make above-mentioned anti-floating crossbeam 32.Particularly, two 10# channel-section steels 320 are put relatively, between two channel-section steels 320, leave the spacing of 10cm, adopt again steel plate that six 15mm are thick as junction steel plate 322, so that the upper and lower surface of channel-section steel 320 is welded, and, being arranged in the aperture of offering Ф 40mm on two relatively middle junction steel plates 322 of six block plates, using the screw hole 324 as above-mentioned.With this, just tentatively form an anti-floating crossbeam 32.
Then, respectively above-mentioned template supporting leg 31 bolts are connected in to the two ends of above-mentioned anti-floating crossbeam 32.Particularly, can select the raw material of channel-section steel as template supporting leg 31, the upper terminal bolt of a template supporting leg 31 is connected in to one of above-mentioned anti-floating crossbeam 32, and the upper terminal bolt of another root template supporting leg 31 is connected in to the other end of above-mentioned anti-floating crossbeam 32, with this, begin to take shape a support body 3.
Finally, just the shell of external mold 2 can be connected with above-mentioned template supporting leg 31.Internal mold 1 is fixedly connected with anti-floating crossbeam 32 by two connecting screw rods 4 (being bidirectional modulation screw rod).Particularly, the upper end of connecting screw rod 4 is connected in the screw hole 324 of junction steel plate 322, and the lower end of connecting screw rod 4 is connected in the top of internal mold.
In this way, internal mold 1 is connected in one with external mold 2 the most at last.In the time of concreting, internal mold 1 just can not produce floating.And after having built, only need be from internal mold 1 fech connection screw rod 4.
Complete after above-mentioned implementation process, should be able to embody following characteristics of the present utility model:
1), by connecting screw rod 4, internal mold 1 is connected on anti-floating crossbeam 32 flexibly;
2) by template supporting leg 31, to be fixedly connected with external mold 2, and coordinate anti-floating crossbeam 32, internal mold 1 and external mold 2 are connected in one.
Below embodiment has been described in detail the utility model by reference to the accompanying drawings, and those skilled in the art can make many variations example to the utility model according to the above description.Thereby some details in embodiment should not form restriction of the present utility model, the utility model by the scope defining using appended claims as protection domain.
