Abstract
The utility model relates to a sound absorbing slab which comprises a sound absorbing slab (1), a dragon bone (2) and a T-shaped batten (9). The utility model is characterized in that the inner part of the sound absorbing slab (1) is provided with a netted reinforcing rib slab (3) along flat surface direction; the sound-absorbing slab (1) is rectangular; two opposite sides of the sound absorbing slab is provided with concave steps (4); one of the two opposite sides is provided with a tenon (5) and the other one of the two opposite sides is provided with a groove (6); the tenon (5) is engaged with the groove (6). The inner part of the sound absorbing slab is added with a reinforcing rib slab which is arranged in the middle part of the dragon bone, so sound absorbing materials can not sink and the sound absorbing and noise reducing effect can not be affected. In addition, as one side of each sound absorbing slab is provided with a tenon and the other side is provided with a groove, the utility model has convenient and safe assembly, fire resistance and no environment pollution.
Description
Technical field
The utility model relates to a kind of building finishing material, especially relates to a kind of abatvoix.
Background technology
Building finishing, especially some big-and-middle-sized assembly halls, senior classroom, when cinema builds, all will be on the interior metope of building and ceiling dress shop sound absorbing layer, to reduce room noise as far as possible, improve its environmental quality.And existing damping material is generally the porous material made from glass fibre cotton, ore deposit cellucotton, aluminum fiber cotton etc., employing nails on wood frame or metal framework is installed on body of wall, will be with loose glass fiber or other damping material of glass fabric or other material parcel, be filled in the space of framework, the surface sheet material that is drilled with some apertures, or the metal structure plate sealing of band sound-absorption hole; Also have with plank in addition and make base plate, load onto sponge, with the bunting parcel, make prefabricated component, the method that is embedded on the body of wall is made abatvoix.
The method of above-mentioned absorbing sound and lowering noise, have following shortcoming: the former adopts fill method to implement absorbing sound and lowering noise, its sound-absorbing effect is limited by the perforated percentage of panel, be difficult to reach the good sound absorption effect: and existing damping material is puffy more, want to reach absorbing sound and lowering noise effect preferably, then need bigger thickness, because whole abatvoix thickness increases, therefore to improve frame relatively and spread its thickness of framework and intensity etc., further increase cost; And these damping materials are for a long time under the impact of sound wave and under the effect of deadweight, and material can sink, and makes and forms cavity in the framework, influences sound-absorbing effect; The construction cost height, long in time limit, efficient is low; In construction or using, damping material come off or efflorescence after, be suspended in the interior space, environment is polluted, human body is caused discomfort.The latter implements absorbing sound and lowering noise with the method for prefabricated component, owing to adopt sponge to make damping material, sound-absorbing effect is bad, and, when sponge is met high temperature, can produce pernicious gas, human body is worked the mischief, and also inflammable, be unfavorable for fire-fighting.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and the sound-absorbing sheet material that a kind of sound-absorbing effect is good, easy for installation, safety is fire-retardant, free from environmental pollution is provided.
The utility model is achieved in that a kind of abatvoix, comprises acoustic tile, keel, T type press strip; Described acoustic tile is made by fire-retardant damping material, and there is a netted reinforcement gusset its inside along in-plane; Described acoustic tile is square, and wherein relative both sides are provided with the concave station rank, one side in addition relatively both sides be provided with tenon, another side is provided with groove, tenon and groove match.
The thickness of the thickness of described keel and the concave station of acoustic tile is adaptive.
Described T type press strip (9) both sides, top width approximates keel (2) width and concave station rank (4) width sum.
When the utility model was installed, horizontal or vertical direction nailed on the keel of pair of parallel on body of wall, and the space near the outside of keel, nails on a pair of internal space apart from being the keel of acoustic tile width apart from being the width of acoustic tile successively in two keel; Acoustic tile is contained in the middle of the keel, the end face tenon of one acoustic tile inserts in another acoustic tile groove, push down the concave station rank of acoustic tile in the two adjacent keel with T type press strip, T type press strip is firmly embedded in the crack of two adjacent keel, utilize the elastic force of keel to clamp T type press strip, make abatvoix fixedly on the wall.
Because the inside of acoustic tile has added the reinforcement gusset and has been to be contained in the middle of the keel, damping material can not sink, and can not influence the effect of absorbing sound and lowering noise, and because each piece abatvoix all is to establish tenon on one side, the other end is established groove, assembles very convenient, and safety resistance alkene, free from environmental pollution.
Description of drawings
Fig. 1 is the structure chart of the utility model acoustic tile;
Fig. 2 is an installation drawing of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments explanation the utility model.
As shown in Figure 1, a kind of abatvoix, comprise acoustic tile (1), keel (2), T type press strip (9), described acoustic tile (1) is inner to have netted reinforcing rib plate (3) along in-plane, and to increase the compressive strength on plane, acoustic tile (1) is a rectangle, wherein relative both sides are provided with concave station rank (4), be made as tenon (5) on one side in the relative in addition both sides, another side is made as groove (6), and tenon (5) matches with groove (6).
The thickness on the concave station rank (4) of the thickness of described keel (2) and acoustic tile (1) is adaptive.
Described T type press strip (9) both sides, top width is keel (2) width and concave station rank (4) width sum.
Described acoustic tile is by hard paper or plastic sheet, fills the cellulose fibre that has fire retardant in the grid of strengthening gusset.
As shown in Figure 2, when the utility model is installed, horizontal or vertical direction nails on the keel (2) of pair of parallel on body of wall, the interior space of two keel (2) distance is the width of acoustic tile (1), near the outside of fixing keel (2), nail on a pair of internal space successively apart from being the keel (2) of acoustic tile (1) width; Acoustic tile (1) is contained in keel (2) centre, the end face tenon (5) of one acoustic tile (1) inserts in the end face groove (6) of another acoustic tile (1), push down the concave station rank (4) of acoustic tile in the two adjacent keel with T type press strip (9), T type press strip is firmly embedded in the crack of two adjacent keel, utilize the elastic force of keel to clamp T type press strip, make abatvoix fixedly on the wall.
Claims (3)
1. abatvoix, comprise acoustic tile (1), keel (2), T type press strip (9), it is characterized in that: described acoustic tile (1) is inner to have netted reinforcing rib plate (3) along in-plane, acoustic tile (1) is a rectangle, wherein relative both sides are provided with concave station rank (4), be made as tenon (5) on one side in the relative in addition both sides, another side is made as groove (6), and tenon (5) matches with groove (6).
