Description
Technical field
The utility model relates to building field, is specifically related to a kind of noise reduction heat-insulation wall plate for building.
Background technology
In recent years, along with improving constantly of people's living standard, also improve the requirement of habitat condition, along with the development of China's building energy conservation, increasing building uses wallboard thereupon.Existing wallboard is divided into brick panel and its making method, gypsum plank or polystyrene foam plate, and brick panel and its making method function singleness, easily pollutes job site, and without heat preserving sound deadening function, uses less; Although gypsum plank and polystyrene foam plate can protect construction environment, good energy-conserving effect, noise reduction and poor thermal insulation property can not block noise transmission effectively, and coefficient of thermal conductivity is large, affects comfort.
Summary of the invention
The purpose of this utility model is exactly the defect existed for prior art, provides a kind of structure simple, reasonable in design, easy construction, can improve noise reduction heat insulation effect, improves the noise reduction heat-insulation wall plate for building of residence comfort.
Its technical scheme is: noise reduction heat-insulation wall plate for building, comprise the wallboard body of integral type, the cavity of hollow is provided with in described wallboard body, the side of described wallboard body is provided with multiple sound-absorption hole be communicated with cavity, also sound absorption cavity is provided with between each sound-absorption hole and cavity, acoustical cotton is equipped with in described sound absorption cavity, described sound absorption cavity and sound-absorption hole form trumpet-shaped inlet, thermal insulation thermal insulation board is provided with in described cavity, side relative with sound absorption cavity on described thermal insulation thermal insulation board is provided with multiple reflection cambered surface, and described reflection cambered surface is corresponding with each sound absorption cavity to be arranged.
The outside of described wallboard body is provided with heat-insulating, fire-preventing layer.
The both sides of described wallboard body are respectively equipped with inserting groove and fin.
Described acoustical cotton is filled in the junction of sound absorption cavity and suction hole.
The utility model compared with prior art, has the following advantages: structure is simple, and reasonable in design, easy construction, can improve noise reduction heat insulation effect, improves residence comfort, can shorten construction period.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Detailed description of the invention
With reference to Fig. 1, noise reduction heat-insulation wall plate for building, comprise the wallboard body 1 of integral type, the cavity 2 of hollow is provided with in described wallboard body 1, the side of described wallboard body 1 is provided with multiple sound-absorption hole 3 be communicated with cavity 2, sound absorption cavity 4 is also provided with between each sound-absorption hole 3 and cavity 2, acoustical cotton 5 is equipped with in described sound absorption cavity 4, described sound absorption cavity 4 forms trumpet-shaped inlet with sound-absorption hole 3, thermal insulation thermal insulation board 6 is provided with in described cavity 2, on described thermal insulation thermal insulation board 6, the side relative with sound absorption cavity 4 is provided with multiple reflection cambered surface 7, described reflection cambered surface 7 is corresponding with each sound absorption cavity 4 to be arranged.
The outside of described wallboard body 1 is provided with heat-insulating, fire-preventing layer 8.Sound-absorption and heat-insulation fireproofing function can be played by heat-insulating, fire-preventing layer 8.
The both sides of described wallboard body 1 are respectively equipped with inserting groove 9 and fin 10.
Described acoustical cotton 5 is filled in the junction of sound absorption cavity 4 and suction hole 3.The sound of suction directly can be absorbed like this.
During construction, carry out grafting by inserting groove 9 and fin 10 according to real size, predetermined wallboard can be formed.The trumpet-shaped inlet that sound and hot gas etc. are formed by sound absorption cavity 4 and sound-absorption hole 3 enters, carry out after preliminary sound-absorbing or heat absorption through the acoustical cotton 5 in sound absorption cavity 4, remaining sound or hot gas enter in cavity 2, owing to being provided with thermal insulation thermal insulation board 6 in cavity 2, such hot gas can not distribute, and plays good insulation effect; Meanwhile, the sound entered from multiple sound-absorption hole 3 or hot gas are all assembled in cavity 2, and reflect through thermal insulation thermal insulation board 6, get back in cavity 2, and the acoustical cotton 5 oppositely entered in sound absorption cavity 4 carry out sound-absorbing or heat absorption, so effective noise reduction and heat insulation.Because thermal insulation thermal insulation board 6 is provided with reflection cambered surface 7, and reflection cambered surface 7 is corresponding with sound absorption cavity 4, carry out after preliminary sound-absorbing or heat absorption through acoustical cotton 5 like this, remaining sound or heat, after thermal insulation thermal insulation board 6 absorbs, are got back to again sound absorption cavity 4 and sound-absorption hole 3 place through reflection cambered surface 7, are weakened last disappearance gradually, because storeroom exists the existence of cavity and thermal contact resistance, the heat transference efficiency of material monolithic reduces, thus improves heat-insulating property, and reaches the object of noise reduction.Wherein, wallboard body 1 is foamed cement board.This wallboard can the propagation of effective block sound, and erasure effect is excellent, and noise can be made to be reduced to 40-70 decibel, and heat preservation and energy conservation effects is good.
The utility model structure is simple, and reasonable in design, easy construction, can improve noise reduction heat insulation effect, improves residence comfort, can shorten construction period.
