Abstract
The utility model discloses a total-reflection floor of a semi-anechoic room. The total-reflection floor comprises a base layer, a main body layer and a first shock absorption layer arranged between the base layer and the main body layer. The total-reflection floor also comprises a reflection layer and a second shock absorption layer; the second shock absorption layer is connected with the main body layer in a matched manner; the reflection layer is positioned above the second shock absorption layer. Therefore, the vibration isolation effect of the total-reflection floor adopting the two shock absorption layers is enhanced by at least 20 percent than that of the conventional total-reflection floor adopting a single shock absorption layer; meanwhile, due to the reflection layer, the sound reflectivity is over 98 percent.
Description
Technical field
The utility model relates to a kind of semianechoic room total reflection ground.
Background technology
Semianechoic room is that a kind of floor is the sound attenuation room of reflecting surface, and to simulate the room in semi-free space, it utilizes total reflection ground as minute surface, the principle that effective size doubles to be designed.In semianechoic room, as long as sound source is placed on reflection ground, when sound source radiation face becomes a plane with ground, identical in acoustic propagation situation and conventional sound attenuation room.This type of semianechoic room is applicable to heavy industrial equipment and machine construction to carry out acoustical testing.But semianechoic room itself also needs isolating exterior noise, need to carry out shock insulation processing, so the requirement of the ground design of semianechoic room is high.In technology, semianechoic room is entirely launched ground and is generally only adopted common individual layer shock-damping structure now, and its shockproof effect and sound reflection effect have much room for improvement.
Utility model content
The purpose of this utility model is for above-mentioned defect of the prior art, provides a kind of follow-on semianechoic room entirely to launch ground.
For realizing above-mentioned utility model object, the utility model has adopted following technical scheme: a kind of semianechoic room total reflection ground, comprise basic unit, body layer and be arranged on basic unit and body layer between the first buffer layer, it is characterized in that: described total reflection ground also comprises reflecting layer and the second buffer layer, described the second buffer layer and described body layer are matched, and described reflecting layer is positioned at the top of the second buffer layer.
In addition, the utility model also provides following attached technical scheme:
Described semianechoic room total reflection ground also comprises articulamentum, and described articulamentum is arranged between described the second buffer layer and reflecting layer.
Described body layer optimal material is concrete, and its optimum thickness is 200 millimeters.
Described first buffer layer the best is spring, and described the first buffer layer and described basic unit are matched.
Described second buffer layer the best is rubber, and its optimum thickness is 5 millimeters.
Described reflecting layer the best is smooth floor tile.
Described articulamentum optimal material is concrete, and its optimum thickness is 100 millimeters.
Than prior art, advantage of the present utility model is: this semianechoic room total reflection ground also comprises reflecting layer and the second buffer layer on the original basis, and wherein, the second buffer layer and body layer are matched, and reflecting layer is positioned at the top of the second buffer layer.So by two-layer buffer layer, vibration isolating effect has improved at least 20% than individual layer damping, the reflecting layer of simultaneously setting up makes sound reflection rate be greater than 98%.
Accompanying drawing explanation
Fig. 1 is the semianechoic room total reflection ground sectional view corresponding to the utility model preferred embodiment.
The specific embodiment
Below in conjunction with preferred embodiment and accompanying drawing thereof, technical solutions of the utility model are further non-limitingly described in detail.
With reference to Fig. 1, corresponding to the semianechoic room total reflection ground of the utility model preferred embodiment, it is mainly used in simulating semi-free space, the acoustic characteristic of test specialities.This total reflection ground is divided into into 6 layers, and that plays Main Function comprises basic unit 1, body layer 2, the first buffer layer 3 and the reflecting layer 6 that is positioned at the superiors.Wherein, the earth's surface at basic unit 1 Wei Gai semi-anechoic room place, has played the effect of supporting upper strata mechanism; Body layer 2 is the basis on this total reflection ground, plays the effect of load-bearing; The first buffer layer 3 plays isolating affection; Reflecting layer 6 is the top layer on this total reflection ground, sound is played to the effect of physical rules reflection.And play booster action comprise the second buffer layer 4 and articulamentum 5.
Particularly, aforementioned body layer 2 and articulamentum 5 form by concrete for making, and the thickness of body layer 2 is 200 millimeters, and the thickness of articulamentum 5 is 100 millimeters.Above-mentioned the first buffer layer 3 is comprised of many springs, and it is arranged in basic unit 1 equably.And second buffer layer 4 the bests are rubber, thickness is 5 millimeters, has played the effect of auxiliary damping.Above-mentioned reflecting layer 6 the bests are smooth ceramic tile, and it is evenly arranged on articulamentum 5.In the present embodiment, the structure on this total reflection ground is arranged and is followed successively by from the bottom up: basic unit 1, the first buffer layer 2, body layer 3, the second buffer layer 4, articulamentum 5 and reflecting layer 6.
Because this total reflection ground has adopted two-layer buffer layer, its vibration isolating effect has improved at least 20% than common individual layer damping, and what adopt due to the top layer on this total reflection ground again is smooth ceramic tile, so surface is harder, more smooth, audio emission rate is greater than 98%.
It is to be noted; above-mentioned preferred embodiment is only explanation technical conceive of the present utility model and feature; its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection domain of the present utility model.
