As shown in fig. 1-4, an embodiment of the present invention provides a sound-damping stair suitable for an assembly building, including a stair body 1, a sound-insulating plate 7, a sound-absorbing plate 17, and a sound-insulating sheet 16;

at least one stair body 1;

the plurality of bosses 2 are arranged on the stair main body 1 along the extending direction of the stair main body 1 and form a step-shaped structure;

the lower surface of the sound insulation plate 7 is provided with at least two connecting plates 8, and the free ends of the connecting plates 8 are provided with mounting structures 9;

sunken structure 3, the shaping respectively is in the vertical lateral wall and the horizontal lateral wall of boss 2 are suitable for sound insulation board 7 passes through mounting structure 9 joint is in sunken structure 3, in order to fix sound insulation board 7.

The stair body 1 is a prefabricated member in advance in a factory and can be directly installed on site; in this implementation, boss 2 is the triangular prism structure, and a plurality of bosses 2 that set up on stair main part 1 have formed the step of this amortization stair to be convenient for people's walking. Because boss 2 is the triangular prism structure, consequently boss 2 has vertical face and horizontal plane, is equipped with two connecting plates 8 that have mounting structure 9 through the lower surface at sound insulation board 7 to with the quick joint of sound insulation board 7 in the sunk structure 3 of boss 2, thereby reduce people and trample the noise on the horizontal plane of boss 2 and the noise of tiptoe play to the vertical face of boss 2. Because stair main part 1, boss 2, sound-proof board 7 all with the prefab, can be on a large scale at the factory production to through mounting structure 9 and sunk structure 3's setting, make the technical worker directly accomplish mounting structure 9 and sunk structure 3's joint, can install sound-proof board 7 on boss 2, realized installing fast at the scene, it is lower to technical worker's requirement simultaneously, it is long when having shortened the installation, and then improved the installation effectiveness.

As shown in fig. 2, wherein one side of the free end of the connecting plate 8 protrudes outwards to form the mounting structure 9, the protruding direction of the mounting structure 9 is opposite, so that the connecting plate 8 is directly inserted into the recessed structure 3 and is fixed by the mounting structure 9, the sound insulation plate 7 is prevented from moving in the recessed structure 3, and the sound insulation plate 7 is connected with the recessed structure 3 more tightly.

As shown in fig. 3, in the present embodiment, the recessed structure 3 includes a groove 4 and a baffle 5;

the grooves 4 are respectively formed in the vertical side wall and the horizontal side wall of each boss 2;

the baffle 5 is arranged at the opening of the groove 4, and the baffle 5 is provided with a mounting hole 6 allowing the connecting plate 8 to extend into.

The baffle 5 is a rectangular precast concrete plate matched with the side surface of the boss 2, a mounting hole 6 allowing the connecting plate 8 to extend into is formed in the middle of the baffle 5, and the mounting hole 6 is rectangular. The connecting plate 8 is inserted into the recess structure 3 through the mounting hole 6, thereby fixing the sound-insulating panel 7.

The baffle 5 is integrally formed at the opening of the groove 4, and a mounting hole 6 is reserved on the baffle 5.

The free end of the connecting plate 8 is provided with a fixing piece between the side protruding outwards and the hole wall of the mounting hole 6, in this embodiment, the fixing piece can be glue or adhesive, so that the sound insulation plate 7 is mounted on the baffle 5 more stably, and the connection stability of the sound insulation plate 7 and the boss 2 is increased.

In this embodiment, the at least two connecting plates 8 are four connecting plates 8 oppositely arranged on the lower surface of the sound insulation plate 7, so that the stability of the connection between the sound insulation plate 7 and the baffle 5 in each direction is increased.

As shown in fig. 4, a buffer structure 10 is further disposed between the sound insulation plate 7 and the boss 2, and the buffer structure 10 includes:

a plurality of fixing holes 14 respectively formed in the recessed structure 3;

and the fixing rods 11 are molded on the lower surface of the sound insulation plate 7, buffer parts 15 are sleeved at the free ends of the fixing rods 11, and the fixing rods 11 and the buffer parts 15 are jointly inserted into the fixing holes 14.

In this embodiment, bolster 15 is the spring, and dead lever 11 includes first section 12 and second section 13, and first section 12 and sound insulation board 7's lower surface fixed connection, the diameter of second section 13 is less than the diameter of first section 12 to be convenient for establish bolster 15 cover on second section 13, first section 12 also can restrict bolster 15 and be in simultaneously second section 13's position, again will dead lever 11 and buffer 15 insert jointly in fixed orifices 14, make when people trample sound insulation board 7, played the effect of buffering, can further reduce the noise, also reduced sound insulation board 7's degree of wear simultaneously.

The length of the fixing rod 11 along the axial direction is smaller than the depth of the fixing hole 14 along the axial direction, so that when people step on the sound insulation plate 7, the fixing rod 11 provides a buffer space, and further noise is reduced.

As shown in fig. 1, by providing a waterproof and breathable structure on the upper surface of the sound insulation plate 7, the liquid falling on the upper surface of the sound insulation plate 7 is prevented from entering the interior of the sound insulation plate 7, the recessed structure 3 and the mounting hole 6, which is convenient for cleaning the sound insulation plate 7. In this embodiment, the waterproof and breathable structure is a waterproof and breathable film.

The back of the stair body 1 is provided with a sound absorption plate 17, and the connection mode of the sound absorption plate 17 and the stair body 1 can also adopt the connection mode of the sound insulation plate 7 and the lug boss 2. The sound absorption plate 17 can effectively reduce the influence of the noise at the lower part of the stair body 1 on the upper space, and has obvious effect in the building with wall bodies on the two side surfaces of the stair body 1.

Still include sound insulation piece 16, set up and be in the laminating department of stair main part 1 and a wall body and setting are in the laminating department of stair main part 1 and side pillar prevents that the wall body produces resonance with the steel bar structure of stair main part 1 when the concatenation with the wall body at stair main part 1.

As an alternative embodiment, the sound-proof sheet 16 may also be arranged at the joint of the stair body 1 and the two-sided wall body.

As an alternative embodiment, the sound-proof sheet 16 may also be arranged at the joint of the stair body 1 and the two side columns.

Wherein, the sound insulation board 7 and the sound insulation board 7 are made of sound insulation materials, and the sound absorption board 17 is made of sound absorption materials.

The specific operation method comprises the following steps: the stair body 1 is prefabricated in advance to be connected with the platform of installation through grout connecting device between, inserts sound insulation board 7 to sunk structure 3 in through the connecting rod again to utilize mounting structure 9 joint on baffle 5, thereby accomplish being connected between sound insulation board 7 and the boss 2, until accomplishing all sound insulation board 7's installation.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications can be made without departing from the scope of the invention.
