Abstract

The utility model provides an inflaming retarding laminated veneer lumber solid wood fireproof door. The inflaming retarding laminated veneer lumber solid wood fireproof door is used at an entrance/exit of a room in a building, and overcomes the shortcoming that an existing solid wood fireproof door is poor in fire resistance. The inflaming retarding laminated veneer lumber solid wood fireproof door comprises a door leaf frame and a door core veneer. The inflaming retarding laminated veneer lumber solid wood fireproof door is characterized in that the door leaf frame and the door core veneer are respectively formed by overlapping, pressing and bonding veneers which are subjected to wood fire retardant immersion treatment, wherein the thickness of each veneer is 2-3 mm, the number of inflaming retarding veneers used for the door leaf frame is 60-80, the wood texture directions of the veneers tend to be identical, a transverse frame and a longitudinal frame of a door leaf are connected in a joggle joint mode, and the number of the inflaming retarding veneers used for the door core veneer is 30-40. The inflaming retarding laminated veneer lumber solid wood fireproof door has the advantages of having the natural and beautiful texture of solid wood and good toughness and strength; the complete cross section is inflaming retarding from the outside to the inside, eliminating the existing hidden danger that a solid wood door leaf is inflammable, and providing a corresponding mating component for a high-grade building.

Description

Flame-retardant veneer laminated Wooden fireproof door

Technical field

The utility model belongs to building unit, is specifically related to the window in the building.

Background technology

For the excessive exploitation of forest and the consciousness of social environment protection were strengthened in the past, Solid Door, window usage ratio in building reduces gradually, has natural texture attractive in appearance and good toughness and intensity based on wood materials.Along with the recovery of forest and planned development and use and the people pursuit to quality of life, the door of solid wood material, window still have preferably prospect of the application.But in the society fast development, dwelling house and culture, commercial building are day by day tall and big, concentrated, and it is particularly outstanding that the fireproof performance of constructional materials seems.For promoting the fire resistance of wooden building member, in succession there is the fire retardant of coating, impregnated timber to occur.But owing to can only improve the fire resistance on surface or the top layer of solid wood member, be difficult to the fire resistance that integral body is improved the larger Solid Door frame in cross section, the use of Solid Door is restricted.

Summary of the invention

The purpose of this utility model provides a kind of flame-retardant veneer laminated Wooden fireproof door, is used in the import and export of building inner room, overcomes the poor deficiency of existing Solid Door fireproof performance.

Flame-retardant veneer laminated Wooden fireproof door of the present utility model comprises Door leaf frame and door panel, the improvement of doing be Door leaf frame and door panel by through the wood fire retardant impregnation process the overlapping pressurization of veneer bondingly consist of, veneer thickness 2-3mm wherein, the fire-retardant veneer number of plies that Door leaf frame uses is the 60-80 layer, each layer veneer grain of wood direction is tending towards in the same way, anyhow the frame of door leaf adopts mortise structure, and door panel uses the fire-retardant veneer number of plies to be the 30-40 layer.

Good effect of the present utility model is: not only have the natural texture attractive in appearance of solid wood and good toughness and intensity, and from outward appearance to inner essence whole cross section is all fire-retardant, has eliminated the existing inflammable hidden danger of solid wood door leaf, for top-grade building provides corresponding supporting member.

Description of drawings

Accompanying drawing is stereogram of the present utility model.

The specific embodiment

Consult accompanying drawing, thickness is dipped to infiltration at the plates of solid wood 1 usefulness wood fire retardant of 2mm.The veneer that will soak into fire retardant is coated with fire retardant glue, presses overlapping in the same way 80 layers of texture behind the gluing, and bonding one-tenth door leaf laminated veneer lumber solid wood profile pressurizes.By specification door leaf border and interior parting bead under the laminated veneer lumber solid wood profile is cut out of the Door leaf frame of setting, mortise and mortise, the gluing assembling gets flame-retardant veneer laminated solid wood door frame 2 of the present utility model.The veneer that above-mentioned flame treatment is crossed is coated with fire retardant glue, and overlapping 40 layers, pressurize bonding, corresponding size is determined door panel 3 in the corresponding door leaf, in the doorframe 2 of packing into before the doorframe combination.

Claims (1)

1. flame-retardant veneer laminated Wooden fireproof door, comprise Door leaf frame and door panel, the improvement of doing be Door leaf frame and door panel by through the wood fire retardant impregnation process the overlapping pressurization of veneer bondingly consist of, veneer thickness 2-3mm wherein, the fire-retardant veneer number of plies that Door leaf frame uses is the 60-80 layer, each layer veneer grain of wood direction is tending towards in the same way, and the anyhow frame of door leaf adopts mortise structure, and door panel uses the fire-retardant veneer number of plies to be the 30-40 layer.
