Embodiment
The box beam of assembled steel-concrete combined structure of the present utility model, including top plate, bottom plate and it is fixed on top plate and bottom plate
Between web.As Figure 1-4, the box beam top plate of full assembled steel-concrete combined structure described in the utility model is composite bridge
Panel, including the first waveform steel plate 1.1 being fixedly linked with web 3.1,3.2, the top of first waveform steel plate 1.1 are provided with reinforcing bar
Concrete slab 1.2, the end of shear connector 1.3 being welded on the crest of first waveform steel plate 1.1 extends to armoured concrete slab
1.2 it is interior.
When box beam size is smaller, bottom plate is only with straight steel plate 2.1；When box beam size is larger, bottom plate uses combined type,
Specifically, the second corrugated sheet steel 2.2 being fixedly linked with web 3.1,3.2, straight steel are provided with the top of straight steel plate 2.1 of bottom plate
Plate 2.1 be connected at the trough of the second corrugated sheet steel 2.2 by high-strength bolt 2.3, common stress.
Web 3.1,3.2 is the steel plate of waveform configuration, can improve the resist bending ability of web, and the entirety of enhancing box beam is strong
Degree.The connection of web 3.1,3.2 and top plate and bottom plate uses welding structure or/and bolt fastening structure.With web 3.2 and top plate
Connection exemplified by, as shown in Fig. 2 being provided with the I-shaped structure being weldingly connected with first waveform steel plate 1.1 in the end of web 3.2
Connector 3.3, or as shown in figure 4, be welded with overhanging connector 1.4 on first waveform steel plate 1.1, the end card of web 3.2
It is connected between overhanging connector 1.4, both are connected by bolt 3.4.The connection that bottom plate is connected with web can also use above-mentioned knot
Any of structure or two kinds.
During the combined bridge deck of prefabricated top plate, first first waveform steel plate 1.1 is laid on smooth ground, in its crest
Shear connector 1.3 is welded on face, steel form or the air bag consistent with trough shape are filled in trough as inner membrance, then
In framework of steel reinforcement of the top of first waveform steel plate 1.1 according to code requirement assembling reinforcement concrete slab 1.2, coagulation is finally poured into a mould
Soil, forms combined bridge deck.
During prefabricated panel, first according to design size respectively in the corresponding position of the straight corrugated sheet steel 2.2 of steel plate 2.1 and second
Straight steel plate 2.1, is then laid on smooth ground by reserved High-strength bolt hole, and the alignment of the second corrugated sheet steel 2.2 is placed on
Above straight steel plate 2.1, high-strength bolt 2.3 is carried out then according to symmetry principle just to twist, will according to symmetry principle after being fully completed
