Manufacturing method of steel-wood heat-insulated fireproof clean door leaf
The utility model relates to the technical field of home decoration door leaves, in particular to a steel-wood heat-insulated fireproof clean door leaf. The wide variety of doors on the market is dazzling. There are courtyard doors, entrance doors, inner doors, copper doors, fire doors, etc. According to the entrance door can be divided into steel fire doors and wood doors. Steel fire door is a kind of high strength entrance door, but the exposed cold steel plate can not improve the luxury grade. The log door is a kind of gao expensive and soft feeling, but with the lack of forest resources, its consumables are large, the price of wood will be higher and higher, and its anti-theft security function is also very worrying. Steel wood insulation fireproof clean door is a kind of entry door, mainly using the advantages of both, that is, with high strength fireproof anti-theft function and soft and gorgeous wood, but the side of the door leaf is still exposed to the cold steel plate, and the fire performance of the wooden door is poor. Therefore, there is an urgent need for an improved technology to solve the problems in the prior art.

The utility model relates to the technical field of home decoration door leaves, in particular to a steel-wood heat-insulated fireproof clean door leaf. The wide variety of doors on the market is dazzling. There are courtyard doors, entrance doors, inner doors, copper doors, fire doors, etc. According to the entrance door can be divided into steel fire doors and wood doors. Steel fire door is a kind of high strength entrance door, but the exposed cold steel plate can not improve the luxury grade. The log door is a kind of gao expensive and soft feeling, but with the lack of forest resources, its consumables are large, the price of wood will be higher and higher, and its anti-theft security function is also very worrying. Steel wood insulation fireproof clean door is a kind of entry door, mainly using the advantages of both, that is, with high strength fireproof anti-theft function and soft and gorgeous wood, but the side of the door leaf is still exposed to the cold steel plate, and the fire performance of the wooden door is poor. Therefore, there is an urgent need for an improved technology to solve the problems in the prior art.
The utility model aims to provide a steel-wood heat-insulated fireproof clean door leaf, which has both the softness of the original wood door and the safety of the steel-wood heat-insulated fireproof clean door. A first fire-proof expansion seal is arranged on the groove of the outer edge on both sides of the door frame, and a second fire-proof expansion seal is arranged on the side surface of the boss structure at the connecting hinge and the upper and lower ends of the door frame body. The sealing performance of the joint of the door leaf body and the door frame body is greatly improved, so that fire is prevented from passing through the gap, and the fire resistance is greatly improved, thereby solving the problems raised in the background art. In order to achieve the above purpose, the present utility model provides the following technical solutions: a steel-wood heat-insulated fireproof clean door leaf, including a door leaf body and a door frame body. One side of the door leaf body is movable with the door frame body through a hinge, and the other side of the door leaf body is equipped with a door lock; the main body of the heat-insulated fireproof clean door, including flame-retardant MDF, first flame-retardant laminate, door leaf steel plate, door leaf frame, middle lining frame, wooden frame frame, transverse frame and first fire expansion seal. There are two door leaf steel plates connected by the middle lining frame and the cross frame, and there is a wooden frame frame outside the two middle lining frames respectively. The outer surface of the heat-insulating and fireproof clean door steel plate is provided with the first flame-retardant laminate, and the outer surface of the first flame-retardant laminate is provided with the flame-retardant medium density board; the outer edges of the wood frame frame are provided with the first fire-retardant expansion seal in the grooves on the outer edges of the wood frame; the edge of the door leaf body is matched with the door frame body; the door leaf frame adopts honeycomb steel plate structure, and the inside of the door leaf frame is filled with fireproof perlite, which improves the structure and improves the fireproof performance. The middle lining frame includes a long vertical rod, a short vertical rod and a cross rod. The long vertical rod is arranged on the side of the door leaf body away from the door lock. The long vertical rod is connected with a plurality of short vertical rods through a plurality of cross rods. The structure can avoid the door lock. The side of the heat-insulated fireproof clean door frame connected to the hinge, the side of the upper and lower end boss structure is provided with a second fireproof expansion seal, and the door frame body away from the hinge is also provided with a groove, when the door leaf body is closed and a fire occurs, Improve the sealing performance between the door leaf body and the door frame body. The flame-retardant MDF of the heat-insulating and fireproof clean door is arranged on the side of the door leaf away from the hinge to extend outward, and is matched with the groove opened at the end of the door frame body away from the hinge, so as to improve the sealing performance between the door lock side of the door leaf body and the door frame body. The wooden frame is connected to the outside of the middle lining frame through horse nails, which is convenient for fixed installation.
Compared with the prior art, the above-mentioned heat-insulated fireproof clean door has the advantages of reasonable structure. Due to the special structure of the main body of the door leaf, it has both the softness of the original wooden door and the safety of the steel-wood heat-insulated fireproof clean door; The door leaf skeleton with honeycomb structure is arranged inside the main body, and the inside of the door leaf skeleton is filled with fireproof perlite, which improves the fireproof performance and at the bearing capacity and the strength in the penetrating direction; the first fire-proof expansion seal is arranged in the grooves on the outer edges of the two sides of the frame, and the second fire-proof expansion seal is arranged at the connecting hinge of the boss structure of the door frame main body and one side of the upper and lower ends, which greatly improves the door leaf main body and the door frame The sealing performance at the connection of the main body prevents the fire from passing through the gap and greatly improves the fire resistance performance; the thermal insulation and fireproof clean door has simple structure, convenient use, beautiful appearance, the frame and the door panel are completely overlapped, which reduces the labor intensity of workers, greatly shortens the processing cycle, and has strong practicability. It is a novel and creative scheme, which is conducive to popularization and use.
