Abstract
The utility model belongs to the technical field of equipment machinery, specifically say and disclose a sound barrier preparation facilities. Its main technical scheme: including bottom plate, activity set up on this bottom plate with the four sides frame that the sound barrier matches the bottom plate on be provided with the film made by the rubber and plastic material and set up the template that lug crowd that at least two of lug crowd that on this film at least two were provided with the interval was provided with the interval constitutes. This sound barrier preparation facilities can prepare the sound barrier of inhaling the sound hole standard to have the efficient characteristics of preparation.
Description
Technical field
The utility model belongs to plant machinery technical field, relates to a kind of sound barrier preparation facilities concretely.
Background technology
Sound barrier is a kind of effective railroad noise prophylactico-therapeutic measures, and board plug type sound barrier is that i shaped steel column and unit board combine by cross section.The abatvoix face that the acoustic barrier unit board structure used at present is made up of cement gypsum light material, backboard and be sandwiched in fiberboard therebetween, noise reduction layer that sound absorption rock wool is formed forms.Usually, after utilizing mould to prepare overall structure during this sound barrier of current preparation, drill bit is used to form the sound-absorption hole integrally-built panel getting out arrangement.This when directly getting out sound-absorption hole on abatvoix, its sound-absorption hole formed not only lack of standardization but also can by forming the cement of panel, gypsum powder disclose in noise reduction layer, reduces noise reduction and sound-absorbing effect.
Utility model content
The purpose of this utility model is just to provide a kind ofly can prepare specification sound-absorption hole and the high sound barrier preparation facilities of preparation efficiency.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of sound barrier preparation facilities, it is characterized in that: comprise base plate, the quadrilateral frame mated with sound barrier be movably set on this base plate, described base plate is provided with the template that projection group that projection group at least two that the egative film be made up of rubber-plastics material and at least two of being arranged on this egative film are provided with spacing is provided with spacing is formed.
The additional technical feature forming above-mentioned a kind of sound barrier preparation facilities also comprises:
---described projection group is made up of the cylinder projection of spread configuration;
---the axial slices of described cylinder projection is the large trapezium structure in little bottom, upper base;
---described trapezium structure is isosceles trapezoid;
---described trapezoidal be ladder structure of right angle;
---described template is spliced to form soon by one or more template.
A kind of sound barrier preparation facilities provided by the utility model compared with prior art, have the following advantages: one, the egative film be made up of soft materials such as rubber and plastics due to the template forming this device and the projection group be arranged on this egative film are formed, therefore sound-absorption hole projection of preparing that can be complete when separating film pulls out, do not form the destruction to sound-absorption hole, therefore the sound-absorption hole prepared has complete and feature that is queueing discipline, substantially increases yield rate and preparation efficiency; Its two, because the axial slices forming the cylinder projection of this device projection group is that the large trapezium structure in little bottom, upper base is formed, therefore, make the demoulding in preparation engineering convenient.
Accompanying drawing explanation
Fig. 1: be the structural representation of a kind of sound barrier preparation facilities that the utility model provides;
Fig. 2: be A-A cross-sectional view of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, the structure of a kind of sound barrier preparation facilities provided by the utility model and operating principle are described in further detail.
As shown in Figure 1, 2, be the structural representation of a kind of sound barrier preparation facilities provided by the utility model.The structure forming this sound barrier preparation facilities comprises base plate 1, the quadrilateral frame 2 mated with sound barrier be movably set on this base plate, and base plate is provided with the template that projection group 31,32,33 and 34 that the egative film 3 be made up of rubber and plastic or soft material and four of being arranged on this egative film are provided with spacing B is formed.When utilizing this device to produce sound barrier, first template is layered on the base plate of quadrilateral frame 2, first the mud of the cement be stirred and gypsum material formation is laid wherein, form the abatvoix face of sound barrier, then lay the noise reduction layer of fiberboard, the formation of sound absorption rock wool above, then lay back veneer material on top, after solidification, the frame of base plate and activity is removed by back-off, again the template be made up of soft material is removed, can sound barrier be formed.
In the structure forming above-mentioned a kind of sound barrier preparation facilities:
---the projection group forming template is made up of the cylinder projection 4 of vertically and horizontally arranged setting, and the sound-absorption hole of formation both can have been made more regular; And when the axial slices (as shown in Figure 2) of cylinder projection 4 is for isosceles trapezoidal structure that little bottom, upper base is large, when removing template, because the inside of formed sound-absorption hole is little, outside large, therefore convenient when pulling draw ring; Particularly when along when to pull the trapezium structure drawing direction be ladder structure of right angle, when it pulls draw ring, its sound-absorption hole comparatively dark (when projection has certain height, effectively can prevent the top of projection from being formed the surface element of sound-absorption hole and scratch)
---when above-mentioned template is spliced to form by two pieces or polylith formwork, it pulls, and to pull mould convenient.
