Description

Technical Field

[0001] The utility model relates to the technical field of building decoration, in particular to an indoor ground rostrum / stage shock-absorbing and noise-reducing supporting structure. Background Art

[0002] Various large and medium-sized conference rooms, lecture halls, multi-functional halls and places mainly for small performances have high requirements for sound effects, and these places are all equipped with a podium / stage. In traditional technology, the base plate of the ground podium / stage is directly fixed to the steel keel frame grid, and the steel keel frame grid is directly fixed to the floor / ground. There is no effective barrier measure, which will form a sound bridge. After long-term use, vibration and noise will be transmitted to the podium / stage through the steel keel frame grid, resulting in poor shock absorption and noise reduction effects of the podium / stage. Utility Model Content

[0003] Based on the above description, the utility model provides an indoor ground podium / stage shock-absorbing and noise-reducing support structure, which can effectively solve the problems of obvious vibration and poor noise isolation during activities on a traditional steel structure podium / stage.

[0004] The utility model provides a technical solution to the above-mentioned technical problems as follows: an indoor ground rostrum / stage shock-absorbing and noise-reducing support structure, comprising a keel, a reinforced fiber cement board on the keel, a surface material laid on the reinforced fiber cement board, and columns, wherein the columns and the keel form a three-dimensional frame grid structure, and a rubber pad is arranged between the keel and the reinforced fiber cement board; the columns are fixed to the floor / ground by a steel plate, and a rubber pad is arranged between the steel plate and the floor / ground, and the steel plate and the rubber pad are fixed to the floor / ground by expansion bolts.

[0005] As a preferred embodiment, the rubber pad is fixedly mounted on the grid of the keel.

[0006] As a preferred implementation, the columns are galvanized angle steel columns, and the keels are galvanized angle steel keels.

[0007] As a preferred implementation manner, the rubber pad strip and the rubber pad block have a thickness of 5 to 10 mm.

[0008] As a preferred implementation, the width of the rubber pad is consistent with the width of the keel, and the length and width of the rubber pad are consistent with the length and width of the steel plate.

[0009] As a preferred embodiment, the thickness of the reinforced fiber cement board is not less than 25 mm.

[0010] As a preferred implementation, the height of the column is adjustable.

[0011] As a preferred embodiment, the surface material is selected from carpet, stone plastic floor, composite floor, multi-layer solid wood composite floor, cork floor, and floor glue.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0013] (1) A three-dimensional frame grid structure is formed by the columns and keels, and a reinforced fiber cement board is arranged on the keel, and rubber pads and rubber pads are arranged between the keel and the reinforced fiber cement board and between the steel plate under the column and the floor / ground, respectively, to form a double shock-absorbing and noise-reducing structure, which can block the sound bridge and solve the problem that the base plate of the traditional ground rostrum / stage is directly fixed to the keel frame grid, and the keel frame grid is directly fixed to the floor / ground without effective blocking measures. When in use, vibration and noise will be transmitted in the rostrum / stage through the steel keel frame grid, resulting in poor vibration reduction and noise reduction effect;

[0014] (2) The structure is safe, made of common materials, easy to construct, low cost and highly adaptable. BRIEF DESCRIPTION OF THE DRAWINGS
