4results about How to "Sound insulation" patented technology

The invention relates to the technical field of building sound insulation and heat preservation, in particular to a steel frame building internal filling sound insulation structure which comprises a sound insulation connecting structure, the sound insulation connecting structure comprises two steel structure columns, and connecting plates are welded to one sides of the inner walls of the two steel structure columns through a plurality of connecting frames; the inner wall of the steel structure column is filled with an internal polyurethane filling layer; a sound insulation assembly structure is arranged between the two steel structure columns, the sound insulation assembly structure comprises sealing plates fixed between the two connecting plates, and top end mounting frames are mounted at the top ends of the multiple sealing plates; every four sealing plates form a group, and an internal mounting structure is arranged on the inner wall of each group of sealing plates. The sound insulation structure has the advantages that the sound insulation and heat insulation performance is achieved, the dual functions of sound insulation and heat insulation are coordinated, the influence of building settlement and vibration can be effectively resisted, the sound insulation structure is prevented from loosening and falling off, the long-term use requirement of a building is met, the site construction time is greatly shortened, and operation and maintenance convenience is improved.

The utility model relates to composite roof technical field discloses a kind of color steel sheet composite roof, including multiple wooden piles 1, multiple wooden piles 1 top is erected with same wood girder 2, multiple wood side beam 3 are extended in wood girder 2 two sides, steel beam 5 is erected above wood girder 2, steel beam 5 is connected with wood girder 2 top by steel prop 6, wherein multiple steel side beam assemblies are symmetrically arranged in steel beam 5 two sides, tile roof is laid on wood side beam 3, and color steel sheet is laid on steel side beam assembly.The utility model leaves gap between girder and steel beam, forms air layer, and further makes through the staggered lap joint design of tile roof and color steel sheet, cooperates the flow guiding effect of air layer, to form air convection between tile roof and color steel sheet space, forms certain ventilation condition, this unique design not only realizes double waterproof function, more effectively blocks heat conduction and sound propagation, and has the excellent performance of heat insulation and sound insulation.

The utility model relates to a related field of silencing assembly, especially a fan air inlet silencing assembly, including outer frame, silencer, support frame, silencing louver, filter screen, damping plate, first sound insulation board and sound insulation roof plate etc.

The utility model discloses a foaming board for ventilation and heating and a unit shell, the foaming board for ventilation and heating is used for abutting against and sealing a step structure, the step structure is provided with a bottom face and a side face, the foaming board comprises a board body, a protrusion is arranged on the peripheral side of the outer edge of the board body, the protrusion comprises a first end face and a second end face, and the first end face and the second end face are arranged on the board body. The first end face is used for abutting against the bottom face, a strip-shaped elastic sealing piece is arranged on the second end face, the elastic sealing piece is used for extruding the side face, and sealing between the side face and the second end face is achieved by extruding the side face through the elastic sealing piece. The foam board can be installed with the step structure in a matched mode through the protrusions on the outer edge, the side wall of the step structure is completely sealed through the sealing pieces on the protrusions, and due to the fact that the sealing pieces on the periphery of the foam board are in interference fit with the step structure, the sealing pieces are extruded to deform to form a sealing face to achieve the waterproof effect. The structure is higher in efficiency.
