Description
Technical field
The utility model relates to a kind of multifunctional fire-proof sound insulation bar.
Background technology
Compare with masonry structure with traditional concrete, lightgage steel joist body of wall have easy construction, high-strength light, ductility good, be easy to dismantle and the advantage such as resettlement, recoverable and win the extensive favor of people.At present in many countries such as the U.S., Russia, applying the lightgage steel joist system partition board with heat insulation (insulation), fire-resistant, moisture-proof, sound insulation several functions, and forming series of products and carry out factorial praluction.Indoor thermal environment of building is required comfortable while, people also have comfortable demand to the acoustic environment of architecture indoor, not only pay attention to the insulation of the external wall protection body built, sound insulation property, the sound insulation property of internal partition wall (party wall) also obtains the attention of people day by day.
But, even if be filled with the sound absorption materials such as centrifugal next cotton in light steel keel partition, the sound-insulation capability of low frequency can not complete and heavy wall be compared, weighted transmission loss is that the concrete wall of 50bd are compared with light wall equally, in 125hz frequency, the sound insulation factor of concrete partition is 40bd, and the sound insulation factor of light wall is at about 24bd.If there is gap and hole on partition wall, the sound insulation factor of partition wall greatly can be reduced.If the sound insulation factor of partition wall body of wall itself reaches 50bd, and wall has ten thousand/ gap and hole, then comprehensive sound insulation factor will drop to 40bd.In order to prevent the gap between plaster board wall and base layer structure, usually when body of wall surrounding installs keel, be encased inside elasticity of plastics adhesive tape.In addition, when the two-layer gypsum plank in every face, answer the fissure of displacement to install, nexine can not hook, and only to outer jointing, this is little on the impact of Sound insulation for partition amount.But necessary jointing during every face one laminate, 12 ~ 17bd otherwise sound insulation factor will decline.
Utility model content
The purpose of this utility model is: provide a kind of multifunctional fire-proof sound insulation bar, and it can reach fire prevention and sound insulation two large functions simultaneously; Decoration panel planeness is effectively controlled, and construction quality is guaranteed.
The technical solution of the utility model is: a kind of multifunctional fire-proof sound insulation bar, and it comprises sound insulation bar, lightgage steel joist, and described lightgage steel joist side is provided with limit groove, and sound insulation bar side is provided with plug-in unit, and sound insulation bar is embedded in the limit groove of lightgage steel joist by plug-in unit.
Below technique scheme is further expalined:
Described sound insulation bar is silica gel strip.
Described sound insulation bar arranged outside have two columniform rectangular.
The outer narrow inner width of limit groove notch of described lightgage steel joist side.
The utility model has the advantages that: multifunctional fire-proof sound insulation bar of the present utility model, it can reach fire prevention and sound insulation two large functions simultaneously; Decoration panel planeness is effectively controlled, and construction quality is guaranteed; In-site installation is convenient, pollution-free, and saving of work and time significantly improves efficiency of construction; Fire-retardant fireproof, from putting out in second; There is good elasticity and incompressible distortion; Anti-tearly to draw, high pressure resistant, wear-resistant, crashproof shockproof; Ageing-resistant, Long-Time Service does not chap, indeformable.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described further:
Fig. 1 is the sound insulation bar mounting structure schematic diagram of the utility model embodiment;
Fig. 2 is the sound insulation bar mounting structure node schematic diagram of the utility model embodiment;
Wherein: 1 sound insulation bar.
Detailed description of the invention
Embodiment: as shown in Figure 1: a kind of multifunctional fire-proof sound insulation bar, it comprises sound insulation bar 1, lightgage steel joist.Lightgage steel joist side is provided with limit groove, and sound insulation bar 1 side is provided with plug-in unit, and sound insulation bar 1 is embedded in the limit groove of lightgage steel joist by plug-in unit.The outer narrow inner width of limit groove notch of lightgage steel joist side.
As shown in Figure 2, the bar 1 that insulates against sound is silica gel strip.Sound insulation bar 1 arranged outside have two columniform rectangular.Sound insulation bar 1 is also fireproof silica gel weather strip, fire-proof self extinguishing silica gel sealing bar.Famous because of its good fire-retardant fireproof self-extinguishment, technical process first adopts high-quality silica gel materials to make shaping silica gel strip by large-scale extruder, then formed by high room temperature vulcanization, oven dry.Relative to general silica gel strip, heat-resistant fireproof silica gel strip adds fireproof powder unlike in formula, thus the silica gel strip of working it out has superpower fire-retardant fireproof performance, certain safety guarantee effect is more served in the sealing of electronic apparatus, therefore, a lot of people is also called fire proof sealing strip.The design of sound insulation bar 1, abuts against naturally with panel lacing film, and this designs and meets the seal of partition wall, anti-flammability, sound insulation property, the requirement of shock resistance quadruple simultaneously.Can mass customized, lightweight, intensity is higher, refractoriness good, 3 seconds from putting out, there is good elasticity and incompressible distortion, high-low temperature resistant, its original high sealing performance can be maintained between subzero 60 degree to 200 degree, easy characteristic is installed; Through national fixed fire extinguishing system and the strict type inspection of fire retarding component Quality Supervision and Inspection Center 11 sport, 16 times of expansion multiplying powers, far away higher than common fireproof strip expansion multiplying power, more excellent, the significant sound insulation and noise reduction of fireproof performance, properties of heat preservation and energy saving, with all paint, cleaning agent does not react, the certification of SGS environment-protecting asepsis.
It should be pointed out that for the utility model through absolutely proving, also can have the embodiment of multiple conversion and remodeling, be not limited to above-mentioned specific embodiment.Above-described embodiment as just explanation of the present utility model, instead of to restriction of the present utility model.In a word, protection domain of the present utility model should comprise those apparent conversion or alternative and remodeling to those skilled in the art.
