For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0041] like Figure 1-4 As shown, an embodiment of the present invention provides a sound-absorbing staircase suitable for assembled buildings, comprising a staircase body 1, a sound insulation board 7, a sound absorbing board 17, and a sound insulation sheet 16;

[0042] At least one staircase body 1;

[0043] A plurality of bosses 2 are arranged on the staircase body 1 along the extension direction of the staircase body 1 and form a stepped structure;

[0044] The sound insulation board 7 has at least two connecting boards 8 on its lower surface, and a mounting structure 9 is provided at the free end of the connecting board 8;

[0045] The recessed structures 3 are respectively formed on the vertical side walls and the horizontal side walls of the boss 2 , and are suitable for the sound insulation board 7 to be clamped in the recessed structures 3 through the mounting structure 9 to fix the sound insulation board 7 .

[0046] The staircase body 1 is a prefabricated part in the factory and can be directly installed on site. In this embodiment, the boss 2 is a triangular prism structure. A plurality of bosses 2 arranged on the staircase body 1 form the steps of the sound-absorbing staircase, which is convenient for people to walk. Since the boss 2 is a triangular prism structure, the boss 2 has a vertical surface and a horizontal surface. By providing two connecting plates 8 with a mounting structure 9 on the lower surface of the sound insulation board 7, the sound insulation board 7 can be quickly clamped into the recessed structure 3 of the boss 2, thereby reducing the noise of people stepping on the horizontal surface of the boss 2 and the noise of the toes kicking on the vertical surface of the boss 2. Since the staircase body 1, the boss 2, and the sound insulation board 7 are all prefabricated parts, they can be mass-produced in the factory. By setting the mounting structure 9 and the recessed structure 3, the skilled workers can directly complete the clamping of the mounting structure 9 and the recessed structure 3, and then the sound insulation board 7 can be installed on the boss 2, realizing rapid installation on site. At the same time, the requirements for skilled workers are relatively low, the installation time is shortened, and the installation efficiency is improved.

[0047] like Figure 2 As shown, one side surface of the free end of the connecting plate 8 protrudes outward to form the mounting structure 9, and the protruding directions of the mounting structures 9 arranged opposite to each other are opposite, so that the connecting plate 8 is directly inserted into the recessed structure 3 and fixed by the mounting structure 9, thereby preventing the sound insulation board 7 from moving in the recessed structure 3, so that the sound insulation board 7 is more tightly connected to the recessed structure 3.

[0048] like Figure 3 As shown, in this embodiment, the recessed structure 3 includes a groove 4 and a baffle 5;

[0049] Grooves 4 are formed on the vertical side walls and horizontal side walls of each of the bosses 2;

[0050] The baffle plate 5 is arranged at the opening of the groove 4, and the baffle plate 5 is provided with a mounting hole 6 allowing the connecting plate 8 to extend therein.

[0051] The baffle plate 5 is a rectangular precast concrete plate matching the side of the boss 2, and a mounting hole 6 is provided in the middle of the baffle plate 5 to allow the connecting plate 8 to extend therein, and the mounting hole 6 is rectangular. The connecting plate 8 is inserted into the recessed structure 3 through the mounting hole 6, thereby fixing the sound insulation board 7.

[0052] The baffle plate 5 is integrally formed at the opening of the groove 4 , and a mounting hole 6 is left on the baffle plate 5 .

[0053] The connecting plate 8 further comprises a fixing member disposed at a free end thereof, which has a side protruding outward and is connected to the wall of the mounting hole 6. In this embodiment, the fixing member may be glue or an adhesive, so that the sound insulation board 7 is more stably installed on the baffle 5, thereby increasing the connection stability between the sound insulation board 7 and the boss 2.

[0054] In this embodiment, at least two connecting plates 8 are arranged on the lower surface of the sound insulation board 7, and the arrangement of four connecting plates 8 relatively increases the stability of the connection between the sound insulation board 7 and the baffle 5 in various directions.

[0055] like Figure 4 As shown, a buffer structure 10 is further provided between the sound insulation board 7 and the boss 2, and the buffer structure 10 includes:

[0056] A plurality of fixing holes 14 are respectively formed in the recessed structures 3;

[0057] A plurality of fixing rods 11 are formed on the lower surface of the sound insulation board 7 . A buffer 15 is sleeved on the free end of the fixing rod 11 . The fixing rod 11 and the buffer 15 are inserted into the fixing hole 14 together.

[0058] In this embodiment, the buffer 15 is a spring, and the fixing rod 11 includes a first section 12 and a second section 13. The first section 12 is fixedly connected to the lower surface of the sound insulation board 7. The diameter of the second section 13 is smaller than that of the first section 12, so that it is convenient to sleeve the buffer 15 on the second section 13. At the same time, the first section 12 can also limit the position of the buffer 15 in the second section 13. Then, the fixing rod 11 and the buffer 15 are inserted into the fixing hole 14 together, so that when people step on the sound insulation board 7, it plays a buffering role, which can further reduce noise and also reduce the wear degree of the sound insulation board 7.

[0059] 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 board 7, the fixing rod 11 provides a buffer space, thereby reducing noise.

[0060] like Figure 1 As shown, by providing a waterproof and breathable structure on the upper surface of the sound insulation board 7, liquid spilled on the upper surface of the sound insulation board 7 is prevented from entering the interior of the sound insulation board 7 or the recessed structure 3 and the mounting hole 6, so that the sound insulation board 7 is easy to clean. In this embodiment, the waterproof and breathable structure is a waterproof and breathable membrane.

[0061] A sound absorbing plate 17 is provided on the back of the staircase body 1, and the connection method of the sound absorbing plate 17 and the staircase body 1 can also adopt the connection method of the sound insulation plate 7 and the boss 2. The setting of the sound absorbing plate 17 can effectively reduce the impact of the noise under the staircase body 1 on the upper space, and the effect is remarkable in buildings where both sides of the staircase body 1 are walls.

[0062] It also includes a sound insulation sheet 16, which is arranged at the joint between the staircase body 1 and a wall, and at the joint between the staircase body 1 and a side column to prevent resonance between the wall and the steel structure of the staircase body 1 when the staircase body 1 and the wall are spliced.

[0063] As an alternative implementation, the sound insulation sheet 16 can also be provided at the joint between the staircase body 1 and the two walls.

[0064] As an alternative implementation, the sound insulation sheet 16 can also be provided at the joint between the staircase body 1 and the columns on both sides.

[0065] Among them, the sound insulation board 7 and the sound insulation board 7 are both made of sound insulation materials, and the sound absorption board 17 is made of sound absorption materials.

[0066] The specific operation method is as follows: the staircase body 1 prefabricated in the factory is connected with the installed platform through a grouting connection device, and then the sound insulation board 7 is inserted into the recessed structure 3 through a connecting rod, and is clamped on the baffle 5 by using the mounting structure 9, so as to complete the connection between the sound insulation board 7 and the boss 2, until all the sound insulation boards 7 are installed.

[0067] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the present invention.
