Description
Technical Field
The invention relates to the technical field of fireproof doors, in particular to an assembly type sound-insulation heat-insulation fireproof door and an assembly method thereof.
Background
The fireproof door is a door which can meet the requirements of fire-resistant stability, integrity and heat insulation within a certain time, and is a fireproof partition which is arranged between fireproof partitions, evacuation staircases, vertical shafts and the like and has certain fire resistance. The fireproof door has the functions of a common door, has the functions of preventing the fire from spreading and the smoke from diffusing, and can prevent the fire from spreading within a certain time to ensure the evacuation of people. The fire department economic department designates an approved laboratory, the fire door fire resistance test method is tested to be qualified according to the national standard GB _12955 once 2008 of the new fire door, which is implemented from 1 month and 1 day in 2009, and the ministry of economic standards inspection bureau is used for verifying and issuing a verification login certificate and an authorization identifier, which is called as a standard fire door. The main function of the fireproof door is to obstruct flame and smoke and ensure the personal safety of residents when a fire disaster happens, so the fireproof door needs to reach the fire-resistant and heat-insulating limit specified by the standard, for example, a standard class A fireproof door needs to reach 1.5h in both fire-resistant integrity and fire-resistant and heat-insulating property.
In the existing market, the standard fireproof door products mainly have two main types: steel fire doors and wooden fire doors. The steel fireproof door is low in cost, simple in manufacturing process and more popular, and is widely applied to fire-fighting walkways, public building corridors, pipe wells and the like. For example, chinese patent CN201610672071.5 discloses a fire door with high fire endurance for various buildings, the main structure of which comprises a door frame and a door leaf, wherein the door frame is formed by welding cold-formed steel and a metal/inorganic composite plate, and the metal/inorganic composite plate is located between the two parts of the cold-formed steel; the door leaf is embedded in the door frame and formed by welding a steel frame and two metal/inorganic composite plates, and a heat insulation material is filled in a cavity formed by the steel frame and the metal/inorganic composite plates. The hinge is installed at the junction of the door leaf of the fireproof door and one side of the door frame, the door closer is installed at the junction of the top of the fireproof door, and the fireproof lock is further arranged on the door leaf. The fireproof door is mainly formed by welding all components of the fireproof door, and the assembly is not fast and convenient enough.
In addition, there are many problems with the steel fire door technology, such as: the steel panel can only carry out two kinds of decoration modes of electrostatic spraying and pvc membrane cladding, and the door leaf panel can not be made complicated pattern and molding, and the veneer effect is single, so this kind of prevent fire door is multi-purpose in the fire escape way of interior decoration, sparse stair etc. department, can not be used to house interior decoration. In addition, although the manufacturing process of the steel fireproof door is simpler and more convenient than that of a wooden fireproof door, fillers of the steel fireproof door are integrally formed by pressing and molding through perlite particles mixed with glue and additives, the process is time-consuming and labor-consuming, after each door core of the door is filled into a door frame through perlite particles mixed according to the steps, a heavy press is used for heating and pressing for more than 24 hours, a large amount of time is occupied, the industrialization degree of door parts is low, multiple steps depend on manual operation, the assembly is complicated, and the labor cost is high. On the other hand, the fire door is prevented to traditional steel only is absorbed in fire behavior, does not have the sound insulation nature, can't be used for the indoor space that has the demand that gives sound insulation of house.
