Description
Technical Field
The utility model relates to a prevent fire door technical field, especially relate to a strenghthened type steel prevents fire door.
Background
With the development of science and technology, people's lives change with the change of covering the ground, and as socioeconomic development is faster and faster, commercial houses of large brands are gradually appeared in the lives of people, but accidents such as fire disasters are inevitable in the lives. Therefore, most modern commercial houses are provided with fireproof doors between walkways to ensure that the fire does not spread rapidly. The existing fireproof door only can restrain the fire and cannot spread, the heat insulation effect cannot be achieved, the fireproof door is made of some fireproof materials, and the texture of part of the fireproof materials is not hard enough, so that the existing fireproof door is poor in hardness. For this reason, we have designed a reinforced steel fire door to solve the above problems.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the defects existing in the prior art and providing a reinforced steel fireproof door.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the design is a fire door is prevented to strenghthened type steel, including the steel sheet, the quantity of steel sheet is two and has the polyurethane heat preservation through the fixed adhesion of high temperature adhesive between two steel sheets, evenly distributed's through hole is seted up to the inside of polyurethane heat preservation, the inside of through hole is provided with the connecting rod, the both ends of connecting rod respectively with two steel sheets between fixed connection, the outside of steel sheet is through the fixed adhesion of high temperature adhesive even has the flame retardant coating, the outside of flame retardant coating is through the fixed adhesion of high temperature adhesive even has various steel layer, the outside on various steel layer is through the fixed adhesion of high temperature adhesive even has the fire prevention cloth.
Preferably, the fire-proof layer comprises a fire-proof plate and a rock wool plate, the rock wool plate is clamped between the two fire-proof plates, and the fire-proof plate and the rock wool plate are fixedly adhered through a high-temperature adhesive.
Preferably, the connecting rod is made of calcium silicate.
Preferably, a layer of flame retardant coating is coated on the outer side of the fireproof cloth.
The utility model provides a strenghthened type steel prevents fire door, beneficial effect lies in: the reinforced steel fireproof door is firmer than the prior fireproof door by arranging the two steel plates, and the polyurethane heat-insulating layer is clamped between the two steel plates, so that heat transfer can be isolated, and the other side of the fireproof door is prevented from causing a fire due to high temperature; in addition, be provided with the flame retardant coating in the outside of steel sheet and can strengthen the resistant fever performance of preventing fire door, compare in the fire door before, the utility model provides a prevent that fire door has stronger structure and heat-proof quality, and practicality and functionality have all obtained the improvement, are fit for promoting.
Drawings
Fig. 1 is a schematic cross-sectional view of a reinforced steel fire door according to the present invention;
fig. 2 is a schematic cross-sectional view of a fire-proof layer of the reinforced steel fire-proof door of the present invention;
in the figure: 1 steel sheet, 2 polyurethane heat preservation, 3 through holes, 4 connecting rods, 5 flame retardant coatings, 6 various steel layers, 7 fire prevention cloth, 8 PLASTIC LAMINATED, 9 rock wool boards.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Example 1
Referring to fig. 1-2, a reinforced steel fireproof door comprises steel plates 1, wherein two steel plates 1 are fixedly bonded with a polyurethane heat-insulating layer 2 through a high-temperature adhesive, the arrangement of the polyurethane heat-insulating layer 2 can isolate heat transfer, and prevent the other side of the fireproof door from causing fire due to high temperature, through holes 3 are uniformly distributed in the polyurethane heat-insulating layer 2, connecting rods 4 are arranged in the through holes 3, the connecting rods 4 are made of calcium silicate, two ends of each connecting rod 4 are respectively fixedly connected with the two steel plates 1, the calcium silicate product has good heat-insulating property, the arrangement of the connecting rods 4 can not only enhance the stability between the two steel plates 1, but also prevent heat transfer, a fireproof layer 5 is fixedly bonded with the outer sides of the steel plates 1 through the high-temperature adhesive, and the fireproof layer 5 can effectively improve the burning resistance of the fireproof door, the outside of flame retardant coating 5 has various steel layer 6 through the fixed bonding of high temperature adhesive, and the outside of various steel layer 6 has fire prevention cloth 7 through the fixed bonding of high temperature adhesive, and the fire prevention cloth 7's the outside is paintd one deck fire retardant coating, and the setting of fire prevention cloth 7 can the decorative pattern of the different colour lines of free choice, has not only increased the aesthetic property of preventing fire door, also can effectually improve the fire resistance of preventing fire door, and painting of fire retardant coating also can effectually improve the fire resistance of preventing fire door, the utility model provides a prevent that fire door has stronger structure and heat-proof quality, compares in the fire door that prevents before, and practicality and functionality have all obtained the improvement, are fit for promoting.
Example 2
Referring to fig. 2, as another preferred embodiment of the present invention, the difference with embodiment 1 lies in that the fire barrier 5 includes fire shield 8 and rock wool board 9, and rock wool board 9 is pegged graft between two fire shield 8, and passes through the fixed adhesion of high temperature adhesive between fire shield 8 and the rock wool board 9, and fire shield 8 and rock wool board 9 are all splendid fire-proof material, can block flame, protect the interior material of preventing fire door, the fire resistance of preventing fire door that improves greatly for prevent fire door has stronger practicality.
