Description
Technical field
The utility model relates to a kind of air channel.Be specifically related to a kind of modular assembling transformation air channel.
Background technology
Existing building kitchen or transformation air channel, washroom generally use the cement mortar cast to form, its complex manufacturing technology, and the moulding difficulty is bigger, and strict to the later stage maintenance and the finished product protection of product, and the process-cycle is longer, and mould is single can't be made by scale.Therefore the raw material of class air channel use mostly are portland cement, require again simultaneously to possess convenient and own wt are installed can not too high dual characteristics, thereby cause surface thickness thinner relatively, make product strength lower after its moulding, transportation with install in phenomenons such as fracture, arrisdefect, inner guiding device come off often appear.Moreover the therefore raw-material limitations in density of series products, its finished weight is still heavier, finishes later stage assembling construction requirement for restriction because of the air channel has agent structure, so cause the construction working decrease in efficiency, difficulty of construction strengthens, and construct accurate degree and construction quality are difficult to guarantee.
Moreover therefore the class air channel for solving taint of odour and recharging guide pipe and the variable-pressure plate that phenomenon designs, the principle that two bodies are settled respectively, there is more defective, this principle not only can not satisfy the problem of free adjustment air intake height, and inside flow-stop valve is set can't be cleaned and changed, with the influence of environment for use, himself not only can't play design function but also can cause flue to stop up in time.
The utility model content
The purpose of this utility model is the defective that overcomes in the technology of existing air channel, provide a kind of have rational in infrastructure, suitability for industrialized production, in light weight, intensity is high, installation is convenient, cost of transportation is low, long service life, overall cost are low, can prevent effectively that air from pouring in down a chimney the modular assembling transformation air channel of phenomenon.
In order to achieve the above object, the utility model has following technical scheme:
A kind of modular assembling transformation of the present utility model air channel comprises main air duct, guiding device, and described main air duct is connected as one by L type connector by some fire-resistant composite panel material modules; Described guiding device comprises water conservancy diversion inclined-plane, transformation plane, fresh air inlet, exhaust vent, wherein, water conservancy diversion inclined-plane, transformation plane surround a box body, the side of this box body is connected with main air duct by L type connector, fresh air inlet is positioned at box body and main air duct junction, exhaust vent is positioned at the top of box body, and the water conservancy diversion inclined-plane is the base plate of box body, and the transformation plane is the side plate of box body.
Wherein, the junction of described some fire-resistant composite panel material modules is coated with anticracking grout, at this anticracking grout place adhering glass fibrous mesh cloth.
Wherein, the described L type connector L type metallic bond fitting that is antirust processing.
Wherein, described fresh air inlet place is provided with the PVC air and returns only valve.
Wherein, the angle of described water conservancy diversion inclined-plane and main air duct wall is less than or equal to 45 °.
Owing to taked above technical scheme, advantage of the present utility model is:
1, utility model is to use the metal connecting piece anchor connection moulding of composite board and antirust processing, its intensity be the prior art structure the air channel 3-5 doubly, and for the monolithic composite board has been realized industrialization, standardized production, improved production efficiency, compare with prior art structure air channel, efficient improves more than 60%.
2, the utility model can need not links such as factory presets, maintenance using on-the-spot assembling flexibly, and transportation loading and unloading is efficient and convenient, and its cost of transportation only is equivalent to 20% of prior art structure air channel.
3, the module-integrated guiding device that adopts of the utility model is a modular integral body, and its aggregate erection is in duct wall one side, and is connected with other both sides, makes it form the transformation pattern, increases the venthole air mass flow, the raising exhaust effect.
4, the utility model guiding device and indoor air inlet go out to be provided with the PVC air and return only valve, this device can satisfy the problem of free adjustment air intake height, and the PVC air returns that only valve can be cleaned and changed according to mode of occupation, and valve is arranged on the outside, air channel so can not cause the flue obstruction because of service life and fault because of the PVC air only returns.
