Description
Technical field
The utility model relates to industrial circle Noise measarement and field of environment protection, is specifically related to a kind of transformer station soundproof door combining structure.
Background technology
Along with the raising of people's living standard, people get more and more to the demand of electric power, and transformer substation in city is built in a large number at residential neighborhood, and transformer station's noise unavoidably affects the live and work of people.The walls and roofs of indoor substation generally adopts heavy type structure, and sound insulation factor is higher, but door generally adopts traditional preparation method, and after use after a while, along with the aging of weather strip and the distortion of door, the gap of door leaf and doorframe is increasing.The sound insulation factor of door becomes the weak link of indoor substation sound insulation.
Utility model content
Of the present utility model
objectjust be to provide a kind of transformer station soundproof door combining structure for above-mentioned deficiency, the utility model changes traditional soundproof door preparation method, from reduction close the door gap and improve door leaf sound insulation factor two aspect improve, substantially increase the sound insulation factor of door.The present invention adopts multistage sealing, and sealing joint strip adopts the weather strip of different cross section, and door leaf have employed the sandwich construction for transformer station's noise frequency noise characteristic, has used the stereotype that surface density is higher and the damping sheet suppressing steel plate to vibrate.In transformer station place through application, sound insulation factor increases substantially, with the obvious advantage in industry.
Of the present utility model
technical schemefor:
The utility model transformer station comprises doorframe by soundproof door combining structure and is hinged on the door leaf on doorframe; Described doorframe comprises the step-like doorframe body of two-stage and is arranged on the cubic shape door shield at doorframe body step top, and door shield and doorframe body form three grades of steps, and doorframe body and door shield are made up of section bar frame and the inner core damping glue be filled in section bar frame; Be provided with triangle sealing joint strip in the one-level stepped portions of doorframe body, the two stage steps position between door shield and doorframe body is provided with circular seal adhesive tape;
Described door leaf is made up of galvanized steel plain sheet outer shell and the obturator be filled in galvanized steel plain sheet outer shell, and the sheathed order of obturator ecto-entad is made up of damping sheet, centrifugally glass-wool, stereotype, low frequency cavity resonance acoustical board institute compound successively; It is step-like that door leaf limit is set to three grades of corresponding doorframe shape.
The utility model
beneficial effectas follows: the utility model door leaf and doorframe junction adopt multi-stage stairs to be connected, every layer of step arranges different sealing joint strips, greatly strengthen the sealing of door, decreases slit source sound.Door leaf is multi-layer compound structure, and outside plate adopts the thick galvanized steel plain sheet of 2mm, and galvanized steel plain sheet pastes the thick damping sheet of 5mm behind, reduces the solid-borne sound transmission of door leaf body.Low frequency absorption cotton and acoustical board is increased in the middle of door leaf.The thick stereotype of inner increase 1mm.Improve the mass density of door leaf, multilayer has the combination of different acoustic impedance elastomeric material, ensures that this door has good defening effect at low frequency.

In accompanying drawing: 1-doorframe body; 2-circular seal adhesive tape; 3-triangle sealing joint strip; 4-door leaf limit; 5-2mm galvanized steel plain sheet outer shell; 6-5mm damping sheet; 7-80kg/m
3centrifugally glass-wool; 8-1mm stereotype; 9-low frequency cavity resonance acoustical board; 10-body of wall; 11-hinge; 12-door shelves.
Detailed description of the invention
A kind of transformer station of the utility model soundproof door combining structure embodiment as shown in drawings, its doorframe body 1 adopts built-in connection welding or expansion bolt and body of wall 10 to be connected and fixed.Door leaf limit 4 is while adopt hinge to fix with doorframe body 1.Door leaf forms formation by the order of thick damping sheet 6, the 2mm galvanized steel plain sheet 5 of the thick damping sheet 6,50mm of 2mm galvanized steel plain sheet outer shell 5, the 5mm thick stereotype 8,50mm of thick centrifugally glass-wool 7,1mm thick low frequency cavity damping sheet 9,5mm is sheathed.With hinge (11) for axle opposite house carries out switch with closed.When the door closes, the multistage tongue and groove of door leaf and the multistage rabbeted butt joint of doorframe, 2 grades of sealing joint strips on doorframe (1) comprise circular seal adhesive tape (2) triangle sealing joint strip (3) can guarantee that door leaf and doorframe fit tightly, and reduces gap, thus avoids the leakage sound of soundproof door.
