Detailed description of the invention
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
As shown in Figure 1A, the utility model provides a kind of novel railway roadbed acoustical board, and this kind of acoustical board is the cuboid of haydites of book structure, high-strength modified cement, hydraulic pressure system, and described acoustical board upper surface is mushroom-shaped, soffit has ripple, and upper and lower surface striped is parallel to each other or vertical.Described acoustical board can be installed on track plates 5, described track plates 5 has pre-buried channel flow 4 and track 6, described acoustical board has bolt hole 3, and described acoustical board is mechanically connected by the pre-buried channel flow 4 on high-strength bolt and described track plates 5.
Further, described acoustical board comprises acoustical board mainboard 1 and acoustical board side plate 2, and the ripple of upper surface can be mushroom-shaped ripple 8, as shown in Figure 1B, described acoustical board soffit has ripple 9, the ripple 8 of described acoustical board upper and lower surface and ripple 9, can improve the sound absorption reduction effect of acoustical board; There is arc groove 7 described acoustical board mainboard 1 and acoustical board side plate 2 inside, and described acoustical board mainboard 1 and acoustical board side plate 2 carry out concavo-convex grafting with the track 6 on track plates 5, carry out occlusion spacing.
Described arc groove 7 structure is wedge shape, straight line connects arc, trapezoidal, semicircle or square.Ripple 8 shape stating acoustical board upper surface is mushroom-shaped, and ripple 9 shape of soffit is arc, trapezoidal, semicircle, rectangle or polygon.
Wherein, described acoustical board and track grafting partial shape are arc, and arc is to produce in casting process at acoustical board, material can be entered mould smoothly without dead angle, build closely knit.Be not easy to build compared to the right angle of rectangle, more easily building of arc.
As shown in Figure 1A, 2A, described track plates 5 is laterally fixed by two pieces of acoustical board mainboards 1, described acoustical board mainboard 1 there is interlocking spacing hole 10, two pieces of acoustical board mainboards 1 are built described interlocking spacing hole 10 after assembled getting well, to fix two pieces of acoustical board mainboards 1, make it that relative changing of the relative positions not occur, interlocking spacing hole 10 can be back taper, and fixed effect is more obvious.
