Abstract
The utility model discloses a natural ventilation roof horizontal warehouse which comprises a warehouse body, a roof and a warehouse door. A bottom layer cast-in-place slab is arranged at the bottom of the roof, the top face of the slab is provided with a heat insulation layer, a large prestress type roof plate is further arranged on the top of the roof, and therefore an air interlayer cavity is formed. An air inlet communicated with the air interlayer cavity is formed in a cornice, and an air outlet communicated with the air interlayer cavity is formed in a ridge. According to the natural ventilation roof horizontal warehouse, a hot pressing effect can be used for achieving a natural ventilation effect, due to the fact that the cavity is affected by solar radiation of the roof, the temperature of air is gradually increased in the height direction, the temperature is highest at the air outlet of the ridge, and the temperature is lowest at the air inlet of the cornice. The air density is reduced along with rising of the temperature, the air density is smallest at the air outlet of the ridge, and the air in the cavity flows from low to high due to the hot pressing effect. The natural ventilation roof horizontal warehouse is convenient to use, and capable of achieving natural ventilation of the roof and reducing transferring to heat in the warehouse by the environment. Ventilation energy consumption is achieved, the building requirements for environmental protection and energy saving are met, and grain protection is facilitated.
Description
Technical field
The utility model relate to grain store technical field, particularly a kind of natural ventilation roofing horizontal warehouse.
Background technology
At present, the conventional storehouse type of China's grain depot remains taking segmental roof truss horizontal warehouse and arch bar horizontal warehouse as main, and the part grain depot in Shandong, Henan, Shaanxi has adopted T plate roofing horizontal warehouse.
Broken line roof truss horizontal warehouse and T plate roofing are large roof slab or T plate, and in construction, roof exists plate seam, cause warehouse air-tightness not high; The radiant heat of outside air heat and the sun is incubated by Cang Ding and the conduction of deck, be relatively easy to enter to grain heap upper space in storehouse, and after the door and window on grain heap is closed, this part air is the state that stagnates, constantly absorb the extraneous heat transmitting, form the stewing chamber of hot air.In the time that outside air temperature reduces, due to the thermal inertia of enclosed structure material, in storehouse, also can continue the condition of high temperature for a long time, totally unfavorable to grain storage.
Arch bar horizontal warehouse, the upper and lower boom plate in roof thin (40mm), narrow space between the upper and lower boom plate in roof, cause large storehouse to exist top, storehouse heat absorptivity strong, heat passes in arch very soon, cause the space accumulated heat between upper and lower boom plate, form " vexed top " at Cang Ding, strengthen the transmission to storehouse heat, grain surface temperature raises fast, form the stewing chamber of hot air, in summer high temperature period, in the time that outside air temperature reaches 41 DEG C, temperature between the upper and lower boom plate of Cang Ding reaches as high as 51 DEG C, cause storehouse temperature to reach more than 40 DEG C, the highest grain temperature in top layer reaches 38 left and right, to summer safe grain storage constitute a threat to.
Arch bar plate seam, causes warehouse air-tightness not high simultaneously, has increased the leakage rate of nitrogen or medicament, causes running cost high.
Utility model content
Defect and deficiency that the utility model exists for existing various horizontal warehouses, provide a kind of roofing horizontal warehouse that can natural ventilation.
For achieving the above object, adopt following technical scheme: a kind of natural ventilation roofing horizontal warehouse, comprises warehouse, roofing and door, in roofing bottom, bottom Bars In Poured Concrete Slab is set, plate top surface is established thermal insulation separation thermosphere, at roofing top, prestressed large roof panel is set again, thereby forms an air blanketing chamber; Be provided with the air inlet port, the ridge place that are communicated with air blanketing chamber at cornice place and be provided with the gas outlet being communicated with air blanketing chamber.
Beneficial effect: the utility model utilizes hot pressing function can reach the effect of natural ventilation, because Nei Shou roof, chamber is subject to the impact of solar radiation, increases gradually along short transverse air themperature, and ridge draft outlet place temperature is the highest, cornice intake air temperature minimum; Atmospheric density raises and reduces with temperature, ridge air outlet atmospheric density minimum, and, to realize air mobile from low to high due to hot pressing function for air in the chamber in.The utility model is easy to use, can realize the natural ventilation of roofing, reduces the transmission of environment to heat in storehouse; Ventilation energy consumption, has realized green, energy saving building requirement, is conducive to protect grain.

detailed description of the invention
Embodiment 1: a kind of natural ventilation roofing horizontal warehouse, referring to Fig. 1, warehouse structure adopts cast-in-situ concrete portal frame, and roofing adopts natural ventilation roofing, and warehouse arranges the ancillary facility such as door and helper.Referring to Fig. 2, Fig. 3 and Fig. 4, in roofing bottom, bottom Bars In Poured Concrete Slab is set, at roofing top, prestressed large roof panel is set again, thereby form a larger air blanketing chamber, at cornice place, air inlet port is set, ridge place sets out gas port, utilize hot pressing function discharge hot air.Because Nei Shou roof, chamber is subject to the impact of solar radiation, increase gradually along short transverse air themperature, ridge draft outlet place temperature is the highest, cornice intake air temperature minimum; Atmospheric density raises and reduces with temperature, ridge air outlet atmospheric density minimum.Natural ventilation hot pressing equals to import and export the center discrepancy in elevation and is multiplied by that to import and export atmospheric density poor, and, to realize air mobile from low to high due to hot pressing function for air in the chamber in.And at bottom Bars In Poured Concrete Slab end face, thermal insulation separation thermosphere is set, and reaching the object of heat insulation and heat control in storehouse, in storehouse, the more common horizontal warehouse of temperature is low 4～5 DEG C.The tightness that cast-in-situ reinforced concrete slab (bottom Bars In Poured Concrete Slab 4) is good simultaneously adjusts again the modern grain storage technology such as desinsection to create good airtight guarantee for rich nitrogen, reduce the air leakage of nitrogen, give prominence to the advantage of its energy-saving and environmental protection, greatly reduced later maintenance and operating cost.
