Abstract
The invention discloses improvement of a noise pollution-controlled sound barrier, which is characterized in that: left and right sides of a front panel and a rear panel are provided with b-shaped embedded connecting structures; and the b-shaped connecting structures between adjacent unit panels are engaged through a C-shaped cambered surface connecting piece. The cambered surface engaged connection between the panels ensures high joint strength; the combined sound barrier has high integrity and is tight and soundproof; and the whole sound insulation effect can be improved by over 30 percent. A connecting point has rotational freedom in a certain range, so that units are more flexibly combined and can be assembled into a certain cambered bend, and dies also can be saved. A planar or cambered rear panel extension plate is arranged between two adjacent sound barrier unit rear panels so as to make the sound barrier have larger cambered bend and reduce the glass steel pultrusion dies, and only two dies are needed totally. Therefore, the defects that the conventional sound barrier leaks sound, is deformed, has short service life and high maintenance cost and is difficult to realize cambered bend and the like are better overcome.
Description
Technical field
The invention relates to the improvement to the Control Noise Pollution sound barrier, it is big to relate in particular to a kind of integral rigidity, and the assembling dirigibility is good, makes die needed fewly, and connecting portion does not tightly leak the fiberglass combined type sound barrier of sound.
Background technology
Connection between the existing sound barrier adjacent cells is mostly adopted between concavo-convex spigot-and-socket or two cell board surface of contact to bond with adhesive tape, and for example Chinese patent CN2881876, CN201217783 adopt concavo-convex socket joint connection and resin adhesive bonding respectively.The sound barrier connecting portion intensity that this kind connected mode is formed a little less than, integral rigidity is little, is being subjected to external force to dash, clash into, or with the passing of time material ageing or adhesive tape are aging, and joint face is deformed, and cause adjacent junction the slit to occur, cause defening effect to reduce.
Secondly, because variations such as on-the-spot installation environments, sound barrier can not standardizedly fully be rectangular straight plate structure, and sometimes according to actual conditions, in order to reach better defening effect, partial section can be designed to globoidal structure.Between the existing sound barrier unit, be and be rigidly connected, the arc surfaced structure needs the sound barrier unit of different specification size, shape and forms.And sound barrier is formed ducted body by the panel and the backboard of location, front and back, in fill out acoustic absorbant and form, therefore reality can not form all size and/or shape by cutting again, must independently make the unit, the glass reinforced plastic panel and the backboard that so just need difformity, specification, and glass reinforced plastic panel and backboard are by Mold Making, thus multiple multi-form mould just must be arranged, to satisfy actual needs.Adhesive tape bonding between particularly concavo-convex socket joint splicing or two cell board surface of contact, Mosaic face does not have bending deformation quantity, and therefore different radians need different arcuate dies, cause mfg. moulding die extremely many, and the mould input is bigger.Therefore still having is worth improved place.
Summary of the invention
The object of the invention is to overcome the deficiency of above-mentioned prior art, provides that a kind of not only to connect integral rigidity big, between joint face in conjunction with the firm sound that do not leak, long service life, and the assembling versatility is good, makes the few fiberglass combined type sound barrier of mould.
The object of the invention realizes, mainly improving one is that the assembling of sound barrier unit connects and adopts between panel and panel, between backboard and backboard, interconnects (be called for short between plate connect, non-two sides directly connect) by web member; The 2nd, interconnect and adopt embedded cambered surface obvolvent structure.Thereby overcome the prior art deficiency, realized the object of the invention.Specifically, fiberglass combined type sound barrier of the present invention, form ducted body by glass reinforced plastic panel and backboard and side plate, built-in acoustic absorbant, adjacent cells connects combination, it is characterized in that all there is the embedded syndeton of b shape the panel and the backboard left and right sides, pass through C shape cambered surface obvolvent web member, obvolvent adjacent cells plate b shape syndeton between the adjacent cells plate.
The said C shape of the present invention cambered surface obvolvent web member, the connected mode of obvolvent adjacent cells plate b shape syndeton, main effect, the one, cambered surface obvolvent strength of joint is big, is difficult between connection getting loose; The 2nd, the cambered surface obvolvent connects, and constitutes a kind of curved surface sealing, and the joint face good airproof performance can guarantee that the junction tightly do not leak sound; The 3rd, cambered surface connects, can also make adjacent certain swing degree of freedom that is connected with, can be implemented in swing among a small circle, thereby help assembling sound barrier among a small circle arc-shaped bend, can overcome the concavo-convex socket joint in side and connect and the bonding connected mode of plane resin adhesive, can only form the defective of standardized straight section, thereby improve adaptability the erecting stage, also help reducing the making of mould, improve the dirigibility of design.Embedded cambered surface obvolvent syndeton is similar armful of fist form, and one is the arc indent, another is an arc convex, and both embed obvolvent, constitutes the embedded cambered surface obvolvent of this patent and connects, concrete shape and version, the technician can be appreciated and understood that to have multiple under this design.The present invention is a kind of easyly commonly used to be, the design of panel both sides has the b shape that bends inwards, and the cambered surface obvolvent that the adjacent panels web member adopts adjacent two the b shape structures of obvolvent simultaneously is C shape for example, with about the obvolvent of two b shapes be movably connected.Wherein more preferably a kind of, panel is connected C shape is connected C shape with backboard and makes back to the integrative-structure web member, promptly respectively connect a C shape at batten width two ends, form width roughly with make the web member that sound barrier thickness equates.Certainly the technician is according to the description of instructions and optimization embodiment; under the present invention's design; can make also that some and embodiment have change slightly but the distortion that do not break away from this patent inventive concept; for example the panel dual-side is straight shape, intermediate connector is corner structure; there is one in the obvolvent coupling assembling for approaching right angle bending etc.; all this patent function can be realized, protection domain of the present invention ought to be included in.
The cambered surface obvolvent flexibly connects between the more detailed plate of this patent, by following embodiment, is exemplified explanation.
In addition, for needing the bigger combined type sound barrier of crooked radian, can between adjacent backboard, increase one flat plate or arc backboard extension plate, between the backboard of forming sound barrier, increase a backboard extension plate (not increasing extension plate between panel), can realize that the assembling of adjacent sound barrier unit connects into arcuate structure.Extension plate, a kind of be preferably plate inner face middle part be provided with to projecting inward, can be by the Long Circle web member of C shape web member obvolvent, its limit, left and right sides respectively have can obvolvent backboard both sides b shape syndeton C shape syndeton.
Fiberglass combined type sound barrier of the present invention, relative prior art, the sound barrier unit interconnects, owing to adopt that panel, backboard interconnect separately, connect between plate and adopt embedded cambered surface obvolvent syndeton, not only have the strength of joint height, form the sound barrier good integrity, under external force, also difficult generation distortion, leakage sound, thus the whole stiffness that makes up sound barrier strengthened, strengthened the anti-deformation ability in installation and the use; And arc obvolvent connection, tightly do not leak sound, can improve the whole defening effect of sound barrier more than 30%.In addition, the cambered surface obvolvent connects, and tie point has the certain limit rotational freedom, not only can make between the unit combination more flexible, and make the combination sound barrier can become certain arc-shaped bend, and is strong to fabricating yard adaptability, and can reach the saving mould.Embedded obvolvent connects, and the assembling assembling is simple, connects between plate, also adapts to be transported to the also alternative side plate of structure of on-the-spot big width combination, particularly integral type web member, can omit side shrouding between joint face.In addition, increasing between two adjacent sound barrier unit backboards has flat board or arc backboard extension plate, more can make sound barrier that big arc-shaped bend is arranged, both can make the plane sound barrier, also can make the arcwall face sound barrier by backboard extension plate in the middle of increasing.Significantly reduced the fiberglass pultrusion die.The mould requirement is few, only needs two moulds altogether, mould of panel and backboard, and mould of arc backboard extension plate has been saved die cost greatly; And can make multiple different radian combination.Better solved existing sound barrier panel and had leakage sound, distortion, the life-span is short, maintenance cost is high, be difficult to realize shortcomings such as arc-shaped bend.Panel, backboard similar shape, isostructure are made straight plane sound barrier and are only needed a universal mold, make various arcwall face sound barriers and only need add a small mould in addition and can realize.
Optimize specific embodiment below in conjunction with three; the present invention is further understood in exemplary illustration and help; but the embodiment detail only is for the present invention is described; do not represent the present invention to conceive whole technical schemes down; therefore should not be construed as the technical scheme qualification total to the present invention, some are In the view of the technician, and the unsubstantiality that does not depart from the present invention's design increases and/or change; for example simple the change or replacement of technical characterictic to have same or similar technique effect all belongs to protection domain of the present invention.
