Abstract
The utility model provides a heat insulation magnesite plate fireproof door, which is composed of a door frame and a door leaf that are hinged together, wherein, the door frame and the door leaf frame that composes the door leaf are butt welded by roll forming section steel. The door leaf frame is fixedly provided with door plates that are made of magnesite earth and woven glass fabric. The cavity between the two door plates are filled with fire proofing fibre felt. The utility model is suitable for various fireproof buildings, can not only safely prevent fires and effectively prevent fire spread, but also has the advantages of favorable thermal insulating property, and low cost.
Description
The utility model provides a kind of magnesite plate labeled door that is used for the heat-insulation and heat-preservation of various fire prooves construction.
The labeled door that existing fire proof construction is used, fire proofing materials such as steel generally commonly used or cement are made.Its structure is huge, and weight is very heavy, uses very inconvenient.Particularly during breaking out of fire, the conduction of heat of steel is fast, easily brings disaster to other key departments, is unfavorable for fire prevention.Particularly the door made of cement material is met fire and is easily burst, and more is unfavorable for fire prevention.
The purpose of this utility model provides a kind of novel labeled door, and not only fire safety is reliable for it, can prevent fire spreading effectively, and heat preservation and insulation is good, can obviously reduce manufacturing cost.
The purpose of this utility model is achieved in that the doorframe and the door leaf hinge-coupled of this device.The Door leaf frame of doorframe and composition door leaf adopts the cold-rolled forming section butt joint to be welded into.On Door leaf frame, be fixed with the door-plate that is pressed into magnesite and glass fabric, filling fire proofing firbre felt in the cavity of two door-plates.Also can be according to mode of occupation, the door-plate that a side of two door-plates is pressed into magnesite and glass fabric, the door-plate that opposite side is made with steel plate.But the fire-proof sealing filling of insert heat-insulation and heat-preservation between doorframe and the Door leaf frame wherein is to increase the fireproof reliability.
Because the utility model adopts good magnesite and the glass fabric of thermal and insulating performance to make panel material, raw material wide material sources not only, manufacture technology is simple, can reduce manufacturing cost, and the coefficient of thermal conductivity of material is much smaller than the coefficient of thermal conductivity of steel plate, safe and reliable, so be easy to promote the use of.The surface of this door-plate can be integral with various beautiful strong bonded such as bunting in addition, very easily increases aesthetic feeling.Filling fibrofelt between the door-plate cavity, the fire-proof sealing filling of insert heat-insulation and heat-preservation between doorframe and the Door leaf frame can be prevented fire spreading effectively, reaches fire-retardant purpose.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a kind of concrete structure front view of the utility model.
Fig. 2 is the sectional view of Fig. 1 along the A-A line.
Fig. 3 is the sectional view of Fig. 1 along the B-B line.
According to Fig. 1～3, describe concrete structure of the present utility model in detail.The doorframe 1 of this device and door leaf connect with hinge 6.Wherein the Door leaf frame 2 of doorframe 1 and composition door leaf adopts the cold-rolled forming sections butt joint to be welded into.Door leaf is made up of Door leaf frame 2, lacing wire 5, door-plate 3.The door-plate 3 usefulness magnesites and the glass fabric that wherein are packed on the Door leaf frame 2 are pressed into.Filling fire proofing firbre felt in the cavity between two door-plates 3.Also can be according to instructions for use, install the door-plate 3 that is pressed into magnesite and glass fabric in a side of Door leaf frame 2, opposite side installs with iron plate and makes door-plate 4, refills the fire proofing firbre felt in the cavity between door-plate 3 and door-plate 4.For realize improving heat preservation and insulation better, prevent fire spreading effectively, can be between Door leaf frame 2 and doorframe 1 fire-proof sealing filling of insert heat-insulation and heat-preservation.Also can in the die cavity of doorframe 1 and Door leaf frame 2, load the fire-proof packing of heat-insulation and heat-preservation in addition.
Claims (3)
1, a kind of magnesite plate labeled door of heat-insulation and heat-preservation, comprise the doorframe and the door leaf that adopt hinge-coupled, the Door leaf frame that it is characterized in that doorframe and composition door leaf utilizes the cold-rolled forming section butt joint to be welded into, on Door leaf frame, be fixed with the door-plate that is pressed into magnesite and glass fabric, filling fire proofing firbre felt in the cavity between two door-plates.
2, labeled door according to claim 1 is characterized in that the door-plate that installs on Door leaf frame, a side is the door-plate that is pressed into magnesite and glass fabric, the door-plate that opposite side can be made with steel plate.
3, labeled door according to claim 1, but it is characterized in that the fire-proof sealing filling of insert heat-insulation and heat-preservation between doorframe and Door leaf frame.
