Background technology
The English spelling of oxygen index (OI) is oxygen index, be abbreviated as OI, refer under rated condition, material carries out the required minimum oxygen concentration of flaming combustion in oxygen-nitrogen mixture stream, represent with the numerical value of the shared percentage by volume of oxygen, and the high expression of oxygen index (OI) material is nonflammable, the low expression of oxygen index (OI) material easily burns, it is generally acknowledged that oxygen index (OI) belongs to combustible material less than 22, oxygen index (OI) belongs to combustible material between 22-27, and oxygen index (OI) belongs to nonflammable material greater than 27.
Polystyrene foam plastics is take polystyrene resin as main body, adds the padded coaming that blowing agent lamp additive is made, and hole-closing structure is arranged, and preferably water-resistance is arranged, and density is little, and mechanical strength is good.
Foam concrete is evenly to mix with cement after the blowing agent foaming, and moulding, and the heat insulating material of a large amount of sealed porositys is arranged.
Heliogreenhouse is a kind ofly not heat indoor, even in the coldest season, also only relies on sunshine to keep indoor certain temperature levels, to satisfy the greenhouse of vegetable crop growth needs.Therefore the night insulation performance of heliogreenhouse is very important, and the night insulation of heliogreenhouse and wall insulation performance have direct relation.Traditional solar greenhouse wall body is for adopting multilayer plastic film, and at one or more layers straw screen or mat of plastic sheeting therebetween or the door curtain made of cloth, and body of wall stable bad easily caused leaking out by wind is moving, makes the heat loss in the greenhouse, and application life is short; Be hollow brick wall perhaps, but heat-insulating property is relatively poor, in order to strengthen heat-insulating property, need to adds thick wall body, the floor space of waste resource and body of wall.
Summary of the invention
In order to solve the problem of above-mentioned existence, the invention discloses a kind of heliogreenhouse heat insulating sandwich wall, this sandwich wall good heat insulating, Stability Analysis of Structures, the more traditional sandwich wall of thickness is thin, saves floor space, and can use for many years, has prolonged the sandwich wall life-span.
Heliogreenhouse heat insulating sandwich wall comprises sandwich layer, and the both sides of sandwich layer are provided with the steel rack, and the outer skin of steel rack is coated with cement layer, and inner surface is provided with brick wall.
Described sandwich layer is that oxygen index (OI) is not less than 30 flame-retardant polystyrene plastic foamboard.
Described sandwich layer is the foam concrete plate.
Described steel rack is in the horizontal direction cross by cold drawn wire and is arranged vertically, and at criss-cross contact point perpendicular vertical cold drawn wire is set, and the contact point welding of cold drawn wire is fixing.
The surfaces externally and internally of described steel rack arranges the cold drawn wire of inclination, and the cold drawn wire of inclination passes through the contact point of the cold drawn wire on the diagonal, and is welded and fixed with it.
Be filled with oxygen index (OI) in the space in the described steel rack and be not less than 30 flame-retardant polystyrene plastic foamboard.
The diameter of described cold drawn wire is not less than 2mm.
The thickness of described sandwich layer is not less than 80mm, and the thickness of cement layer is not less than 30mm, and the thickness cloth of brick wall is less than 400mm.
The present invention; polystyrol plastic foam plate or foam concrete plate have preferably thermal insulation function; heat in the protection greenhouse can not scatter and disappear at night; the steel rack makes the stabilized structure of sandwich wall; cement layer stops water to enter in the sandwich wall; material in the sandwich wall is played the effect of protection; prolong the life-span of sandwich wall; when the flame-retardant polystyrene plastic foamboard can be avoided breaking out of fire; fire spreading; play the safeguard protection effect, brick wall plays the effect of load-bearing, makes body of wall can bear larger blast and crushing by snow.
