Description
Technical field
The present invention relates to a kind of building board, particularly, relate to a kind of three-dimensional grid structure building board.
Background technology
Because people's living standard improves, people are concerned about quality of life more, require improving constantly to the acoustic enviroment of life, work, inhabitation.
Along with Urbanization Process In China constantly advances, the population density increases, and land resources becomes more precious.Due to improving constantly of Building technology level, the development of constructional materials and construction technology, increasing multilayer, Development of High-rise Buildings are got up.A large amount of building adopts reinforced concrete structure, towards high-rise, large bay future development.The development of building structure, makes a large amount of light wall board materials be applied to enclosure wall and the partition wall of building.The application of light wall board material, alleviates the load of structure, saves steel, cement, reduces construction costs, increases the usable floor area of building interior, and easy for installation.In order to reach the effect of good sound absorption, adopting thick and heavy wallboard in a large number at present, occupying larger usable floor area; And once adopt frivolous wallboard, sound insulation property can be caused again to be difficult to meet the demands.
Such as, Chinese patent Authorization Notice No.: CN203905280U, authorized announcement date on October 29th, 2014, disclose a kind of lightweight fireproof insulating Acoustic barrier plate, comprise: the first panel, the second panel, sound absorption heat insulating material and lightgage steel joist framework, the first panel and the second panel between the sound absorption heat insulating material that is provided with, the first panel of being fixed on of the lightgage steel joist framework that passes through of sound absorption heat insulating material and the second panel between.In that patent, although employ lightgage steel joist framework, because keel frame is fixed between surface course, when room temperature acute variation, wallboard and keel frame shrink inconsistent, easily cause the cracking of body of wall.In addition, although this wallboard reaches the effect of sound insulation to a certain extent, the poor effect of sound insulation, still can not meet the more and more higher acoustical demands of people.
Summary of the invention
For the technological deficiency of existing building sheet material, the invention provides a kind of novel, that there is excellent sound insulation performance muffler building board, in less thickness dimension, reach higher defening effect, and have higher intensity, being applicable to insulate against sound requires in higher construction wall.
The object of this invention is to provide a kind of building board, this building board is three-dimensional grid structure, comprise the surface course being positioned at sheet material both side surface, middle soundproof course between surface course, the light sandwich layer in space is filled between surface course and middle soundproof course, surface course and middle soundproof course use sound insulating material or composite sound-insulation material to make, light sandwich layer uses sound absorption material to make, also comprise keel, keel are between surface course and middle soundproof course and connection table surface layer, wherein keel are arranged perpendicular to surface course in middle soundproof course both sides, keel and middle soundproof course is one-body molded or keel and middle soundproof course and surface course three in one shaping, form three-dimensional grid structure.Use keel to connect middle soundproof course and surface course in the present invention, improve the crush resistance strength of sheet material, add the bulk strength of sheet material.And, keel use identical or that Main Physical Characteristics is similar material one-body molded with middle soundproof course and surface course, in use they keep identical or close shrinkage degree along with the change of environment temperature, further ensure building board intensity in use, such sheet material is in use not easy cracking.
Above-mentioned building board, middle soundproof course is dull and stereotyped or corrugated sheet, and corrugated sheet has crest and trough, and the crest of corrugated sheet and trough are acute angle and/or arc.Due to the characteristic of Acoustic Wave Propagation, use corrugated sheet as middle soundproof course, can effectively stop passing of sound wave, thus improve the sound insulation property of sheet material.
Above-mentioned building board, keel are arranged or asymmetric setting in middle soundproof course bilateral symmetry.When asymmetric setting, the keel of middle soundproof course both sides are in staggered distribution in the both sides of middle soundproof course, and keel extend and at the both sides spaced set of middle soundproof course on the width of sheet material on panel length direction.Keel are evenly arranged in middle soundproof course both sides, sheet material can be made to keep intensity consistent in whole length with width, there will not be region of stress concentration.
Above-mentioned building board, also comprises one or more damping layer, and one or more damping layer is pasted on the inner side of surface course, or is pasted on cavity inner wall that surface course, middle soundproof course and keel three form jointly.Use damping layer in sheet material inside, sound insulation effectiveness in vibration suppression can be increased substantially.
Material selected by above-mentioned building board, damping layer is high-molecular organic material.Surface course, middle soundproof course and keel material used is silicate material or gypsum material or metal material or macromolecular material or their combination.Light sandwich layer material used is porous absorption material or fiber cotton like sound absorption material or expanding material.
Above-mentioned building board, the side that two of MULTILAYER COMPOSITE rack sound barrier are relative has the Fastening tenon structure of fit shapes.Fastening tenon structure is protruding and groove fit.Fastening tenon structure is that the bending of extending from main body coordinates.In Fastening tenon structure, also there is middle soundproof course and/or damping layer.Use Fastening tenon structure, sheet material engages mutually in an installation, increases the reliability of sheet material connection and overall sheet material bonding strength.
Building board provided by the invention, soundproof course in the middle of adding separately between two surface courses, and fill the light sandwich layer of sound absorption, ensure that sound insulation and sound-absorbing effect, structural strength is substantially increased after adding keel, surface course, middle soundproof course and keel one-body molded, avoid sheet material keel when shrinking strut or depart from surface course and/or middle soundproof course and cause the reduction of intensity, this design has excellent sound-proof sound-absorbing performance, also there is good heat-insulating property simultaneously, simple and reasonable, intensity is high, quality is light, volume is thin, fire prevention, environmental protection, easy to install, manufacturing process is simple, cost is low.
Other features and advantages of the present invention are described in detail in detailed description of the invention part subsequently.
