Detailed Description

The technical scheme of the invention is further explained by combining the attached drawings.

As shown in figures 1-2, the assembled breast board comprises a bridge board 1 and a breast board 2, and is different from the existing on-site formwork erecting pouring mode, the breast board 2 and the bridge board 1 are connected in an assembling mode, namely, the breast board 2 and the bridge board 1 are prefabricated and then are assembled on site, and are not connected through concrete pouring after on-site formwork erecting.

Specifically, as shown in fig. 1, because breast board 2 locates bridge slab 1 side, so set up spread groove 3 on bridge slab 1 side surface, bridge slab 1 in the spread groove 3 outside then forms one and prevents bank 4 like this, breast board 2 bottom is equipped with connecting seat 5 that is fixed in spread groove 3, breast board 2 bottom outside establishes pterygoid lamina 6, fix breast board 2 in spread groove 3 through connecting seat 5, pterygoid lamina 6 bottom surface then laminates with preventing bank 4 upper surface, wherein connecting seat 5 and pterygoid lamina 6 all pass through concrete placement integrated into one piece with breast board 2 when prefabricating, through addding pterygoid lamina 6 like this, further reduce the focus of breast board 2, and pterygoid lamina 6 forms the restraint with preventing bank 4, make breast board 2 more stable after the assembly.

Because the breast board 2 has a certain height, when the breast board is impacted, the upper part of the breast board 2 is more easily damaged due to larger moment, and therefore a reinforcing mechanism is arranged between the upper part of the breast board 2 and the reverse bank 4 to improve the impact resistance of the upper part of the breast board 2.

With reference to fig. 1 and 2, the water draining groove 16 is formed in the upper surface of the connecting seat 5 on the inner side of the breast board 2 for daily water draining, and the height of the top surface of the water draining groove 16 is smaller than the height of the side edge of the top surface of the connecting seat 5, namely, the top surfaces of the connecting seats 5 on the two sides of the water draining groove 16 are inclined from the outside to the water draining groove 16, so that water flows into the water draining groove 16 conveniently. A plurality of bosses 17 are arranged in the drainage groove 16 at equal intervals, drainage holes 18 are formed in the bottoms of the drainage grooves 16 between every two adjacent bosses 17, the drainage holes 18 are communicated with drainage pipes 19 in the bridge plate 1, and water flow is discharged through the drainage holes 18 and the drainage pipes 19.

The reserved hole 20 is formed in the boss 17, the embedded part 8 is arranged in the bridge plate 1 below the boss 17, the embedded part 8 upwards penetrates through the reserved hole 20 and then is connected to the anchoring nut 9, the anchoring nut 9 is screwed down after the breast boards 2 are assembled, the connecting seat 5 and the embedded part 8 are anchored, and then the breast boards 2 are fixed on the bridge plate 1. The boss 17 is arranged to form a height difference with the bottom of the drainage groove 16, so that the possibility that the anchoring nut 9 is immersed by accumulated water in the drainage groove 16 for a long time is reduced, and the service life of the anchoring nut 9 is prolonged.

The reinforcing mechanism adopted by the invention comprises a reinforcing plate 12, an ejector rod 11 and a steel sleeve 7, and particularly as shown in figure 1, the reinforcing plate 12 is embedded in the upper part of the breast board 2, and the steel sleeve 7 is embedded in the reverse ridge 4 in advance. One end of the ejector rod 11 is rotatably arranged in the steel sleeve 7, specifically, a fixed shaft 10 is arranged in the steel sleeve 7, and the end part of the ejector rod 11 is sleeved on the fixed shaft 10; the other end of the ejector rod 11 is detachably connected with the reinforcing plate 12, specifically, the ejector rod 11 can be connected with the reinforcing plate 12 through bolts, the breast board 2 is fixed firstly during assembly, and then the ejector rod 11 is connected with the reinforcing plate 12. Because the top rod 11 needs to pass through the wing plate 6, an opening 15 for the top rod 11 to pass through is naturally formed in the wing plate 6, and finally the top rod 11 carries out inclined support on the upper part of the breast board 2 so as to improve the impact resistance of the upper part of the breast board 2.

In addition, the inner side of the reinforcing plate 12 is provided with a connecting plate 13, the connecting plate 13 and the reinforcing plate 12 are integrally formed, the connecting plate 13 is welded with longitudinal steel bars 14 in the breast board 2, and the longitudinal steel bars 14 in the breast board 2 are vertically arranged, so that when the breast board 2 is prefabricated, the connecting plate 13 can be clamped between the upper row of longitudinal steel bars 14 and the lower row of longitudinal steel bars 14, then the connecting plate 13 is vertically welded with the longitudinal steel bars 14, and pouring is performed, so that the impact resistance of the longitudinal steel bars 14 can be improved, and the strength of the breast board 2 is further improved.

Finally, the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered in the claims of the present invention.
