Description

Sound-absorbing and sound-insulating cement-based assembled enclosure wall board

Technical Field

The utility model relates to an entity enclosure wallboard, material use cement base to give first place to, through the inside bubble chamber that communicates each other, reach and inhale sound syllable-dividing effect, still keep the durability of concrete simultaneously.

Background

The transformer substation or the converter station can produce great noise during operation, for not influencing the surrounding environment, noise pollution abatement, according to the noise control requirement, generally can set up the sound insulation barrier of different heights above the entity enclosure. The former engineering types are solid enclosing wall and sound insulation barrier. The solid enclosure is a cast-in-place frame structure or an assembled enclosure, the sound insulation barrier is mainly made of steel upright posts, and the sound insulation barrier is welded or fixed on the columns of the solid enclosure through steel plates and then added with sound insulation boards.

This type of noise control is desirable, but has certain disadvantages. Firstly, the solid enclosing wall only plays a role in blocking and does not play a role in sound insulation; secondly, steel plates or embedded foundation bolts are required to be arranged on the columns of the solid enclosing wall, so that the construction difficulty of the solid enclosing wall is increased, and a working procedure is also added for installing the sound insulation barrier at the later stage; thirdly, the difference between the material and the shape of the solid enclosing wall and the sound insulation barrier is large, and the enclosing wall gives people a split feeling.

Disclosure of Invention

The utility model aims to provide a wallboard weatherability is good, and long service life has reduced the construction process, inhales the sound insulation effect and is showing one kind inhale sound insulation cement base assembled enclosure wallboard.

The utility model discloses a task is accomplished like this, its characterized in that: the wall panel is formed by pouring a three-layer structure, the three-layer structure comprises a bare concrete solid wall panel, a porous material sound-insulating layer and a transverse stripe layer, the bare concrete solid wall panel faces the outside of the station and the transverse stripe layer faces the inside of the station, the porous material sound-insulating layer is clamped between the bare concrete solid wall panel and the transverse stripe layer, and a clamping groove for clamping the wall panel is arranged on the wall column.

The fair-faced concrete solid wallboard is made of fair-faced concrete, the surface of the fair-faced concrete solid wallboard is a smooth surface, and the surface, facing the station, of the transverse stripe layer is a regular concave-convex layer.

The utility model discloses has following effect: 1. the wallboard material is mainly made of cement-based materials, and has good weather resistance and long service life.

2. The appearance of the enclosing wall is still the clear water concrete process, the whole body is kept consistent, the fracture feeling of the solid enclosing wall and the sound insulation barrier is avoided, and the feeling of consistency and bulkiness is given to people.

3. The enclosure is whole homoenergetic to play and to inhale the effect that sound was syllable-dividing, only need accomplish the design requirement height with the entity enclosure according to the noise control requirement, need not do the sound insulation barrier on entity enclosure upper portion, has reduced construction process.

4. Most porous sound absorbing materials are independent holes and have limited noise attenuation. And the porous material that this project wallboard adopted, inside hole are intercommunication, and the noise is through multiple reflection decay inside it, and it is obvious to inhale the sound insulation effect.

5. The horizontal stripe layer in the station can be on the basis of guaranteeing horizontal stripe structure, and the stripe width, the degree of depth, the interval can change, helps promoting the impression of enclosure.

Fig. 1 is a schematic structural diagram of the present invention; FIG. 2 is a side view of FIG. 1; fig. 3 is an installation schematic diagram of the present invention.

FIG. 1 illustrates schematically: 1. clear water concrete solid wallboard, 2, porous material puigging, 3, horizontal stripe layer, 4, enclosure post, 5, draw-in groove, 6, in the station, 7, outside the station.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

The concrete embodiment is shown in fig. 1, fig. 2 and fig. 3, the wall panel is formed by pouring three layers, the three layers comprise a fair-faced concrete solid wall panel 1, a porous material sound insulation layer 2 and a transverse stripe layer 3, the three layers are arranged in sequence towards the outside 7 of the station and are plain concrete solid wall panels, the three layers are arranged towards the inside 6 of the station and are provided with transverse stripe layers 3, the porous material sound insulation layer is clamped between the fair-faced concrete solid wall panel and the transverse stripe layers, and the wall pillars 4 are provided with clamping grooves 5 for clamping the wall panel.

The fair-faced concrete solid wallboard adopts fair-faced concrete, and the surface of the fair-faced concrete solid wallboard is a smooth surface, adopts the fair-faced concrete, and is internally provided with reinforcing bars, and the strength of the wallboard mainly depends on the layer, and the layer faces the station, and the enclosure is still similar to the traditional solid enclosure when seen from the outside of the station.

The sound insulation layer is made of porous materials, and the sound absorption mechanism of the porous sound absorption materials is that when sound waves are incident to the porous materials, air vibration in pores is caused. Part of the sound energy is converted into heat energy due to friction and viscous resistance of air, and in addition, heat loss is caused by heat conduction between the air in the pores and the pore walls and fibers, so that the sound energy is attenuated.

The sound insulation layer of the wallboard is formed into a mutually communicated foam cavity by combining a foaming porous material and a special production process, so that after noise enters the sound insulation layer, the noise is attenuated through multiple reflections, and finally the noise is weakened to be below the noise pollution standard.

The transverse stripe layer faces the station, so that on one hand, the regular concave-convex layering sense is better in the station appearance; on the other hand, the transverse stripes contribute to the entry of noise into the holes of the sound-insulating layer.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally connected, and may communicate between two elements. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
