Abstract
The utility model discloses a kind of prefabricated board of pre-buried ventilation shaft, the prefabricated board at least side is equipped with cavity, and the side of cavity is equipped with orifice plate, several exhaust vents are arranged on orifice plate；The prefabricated board is embedded with ventilation shaft, and one end of the ventilation shaft is deep into cavity inside, and the other end of the ventilation shaft is connect with exhaust apparatus by hose.The utility model provides a kind of prefabricated board of pre-buried ventilation shaft, and wall is made using the prefabricated board, metope outlet air may be implemented, air-out direction is avoided to fix, and cold wind or hot wind blow-through bring sense of discomfort realize circular space wind truly.
Description
Technical field
The utility model relates to building material technical fields, and in particular to a kind of prefabricated board of pre-buried ventilation shaft.
Background technique
Air-conditioning has become essential household electrical appliance in people's life, existing air conditioner air-out direction immobilizes,
It is uneven in temperature, comfort is poor, air-conditioning blow-through is easy to cause a variety of diseases, and cold air is directly blown to human body, gently then cat fever, weight
Then cause allergic dermatitis, constitution decline etc..
Currently, having had already appeared soft comprehensive health on the market around 3d air delivery air-conditioning, which can be carried out
The circular pendulum leaf and 3d air delivery wind wheel of lower left and right automatic adjustment carry out the air-supply of 3 D stereo cross scan formula to air, up and down
Wind deflector independent assortment, but the outlet air site of this air-conditioning is also relatively simple.If by the exhaust vent and prefabricated panel wall of air-conditioning
Cooperation, then indoor wall outlet air can be realized, realizes circular space wind truly.
Utility model content
The purpose of this utility model is that overcome defect existing in the prior art, a kind of pre-buried ventilation shaft is provided
Prefabricated board is made wall using the prefabricated board, metope outlet air may be implemented, air-out direction is avoided to fix, cold wind or hot wind blow-through
Bring sense of discomfort realizes circular space wind truly.
To achieve the above object, the technical solution of the utility model is to design a kind of prefabricated board of pre-buried ventilation shaft, institute
Stating prefabricated board is reinforced concrete structure, and the prefabricated board at least side is equipped with cavity, and the side of cavity is equipped with orifice plate, sets on orifice plate
Set several exhaust vents；The prefabricated board is embedded with ventilation shaft, and one end of the ventilation shaft is deep into cavity inside, described
The other end of ventilation shaft is connect with exhaust apparatus by hose.The ventilation shaft for being embedded in prefabricated component is made of metal material
Pipeline, the pipeline for stretching out prefabricated plate surface is hose ventilation shaft.
It is flare openings that the ventilation shaft, which is deep into the port in cavity, as a preferred technical solution,.It will ventilation
The exhaust vent of pipeline is made into horn-like, buffers the air-flow in pipeline, reduces the noise that fluid issues in the cavities.
Four wall of cavity is equipped with damping sound absorbing layer as a preferred technical solution,.The damping sound absorbing layer is phenolic aldehyde
Resin foam layer reduces the noise of gas in the cavities.
Four wall of cavity and ventilation shaft are equipped with erosion resistant coating as a preferred technical solution,.Prevent the oxygen in gas
Oxidation to ventilation shaft.
The diameter of exhaust vent is 0.2~0.5mm on the orifice plate as a preferred technical solution,.
The ventilation shaft being embedded in prefabricated board as a preferred technical solution, is helical ventilation pipe road.
The orifice plate on the cavity is detachable structure as a preferred technical solution, is equipped with orifice plate slot on the inside of cavity.
The outlet air internal surface of hole is equipped with activated charcoal strainer as a preferred technical solution,.It will be miscellaneous in ventilating system
Matter sprays from venthole after activated charcoal strainer filters, improves the safety of gas.
Advantages and beneficial effects of the utility model lie in that the pre-buried ventilation shaft in prefabricated board, makes metope have outlet air
Effect, current rate is weakened by cavity, the air-flow sprayed from exhaust vent is soft slow, will not cause sense of discomfort to human body, be
Circular space wind truly.

Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is further described.Implement below
Example is only used for clearly illustrating the technical solution of the utility model, and cannot be used as a limitation the protection model of limitation the utility model
It encloses.
A kind of prefabricated board of pre-buried ventilation shaft, the prefabricated board 3 are reinforced concrete structure, the prefabricated board at least side
Equipped with cavity 4, the side of cavity 4 is equipped with orifice plate 5, several exhaust vents 1 are arranged on orifice plate；The prefabricated board is embedded with ventilation duct
The one end in road 2, the ventilation shaft 2 is deep into inside cavity 4, and the other end and the exhaust apparatus of the ventilation shaft 2 pass through soft
Pipe connection.
It is flare openings that the ventilation shaft, which is deep into the port in cavity,.
Four wall of cavity is equipped with damping sound absorbing layer.
Four wall of cavity and ventilation shaft are equipped with erosion resistant coating.
The diameter of exhaust vent 1 is 0.2~0.5mm on the orifice plate.
The ventilation shaft 2 being embedded in prefabricated board is helical ventilation pipe road.
Orifice plate on the cavity is detachable structure, is equipped with orifice plate slot on the inside of cavity.
The outlet air internal surface of hole is equipped with activated charcoal strainer.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvements and modifications can also be made, these change
It also should be regarded as the protection scope of the utility model into retouching.
