Description

Flame-retardant veneer laminated fire-proof wooden door

Technical field

The utility model belongs to the labeled door field, is specifically related to a kind of fire-proof wooden door that utilizes the flame-retardant veneer laminated making of fast growing wood.

Background technology

The doorframe of fire-proof wooden door and door leaf skeleton are the key components of fire-proof wooden door, directly have influence on the fire resistance of fire-proof wooden door.The doorframe of fire-proof wooden door and door leaf skeleton all adopt the high-quality solid wood through flame treatment to be made all the time, but because the thickness of solid wood is big, cause the flame treatment difficulty big, the length of penetration of fire retardant is shallow, usually less than 10mm, make that the flame retardant effect of fire-retardant solid wood is poor, fire-retardant cost height.Also can produce distortion through flame treatment and dried solid wood, in use subsequently, need cut shaping processing to fire-retardant solid wood, so just fire-retardant solid wood top layer is absorbed the maximum part of fire retardant and machined away, both weaken the flame retardant effect of solid wood, caused waste simultaneously again.Along with the minimizing day by day of wildwood resource, the high-quality timber resources is also fewer and feweri, and price rises steadily, and makes the cost of manufacture of fire-proof wooden door increase gradually.And the cultivated area of China's fast growing wood constantly enlarges, and the accumulation of fast growing wood and cutting increase year by year.But because there are some natural defects in fast growing wood, material is lower, and is little as the footpath level, density is low, easy deformation etc., makes fast growing wood be difficult to directly to satisfy the requirement of the doorframe and the door leaf skeleton of fire-proof wooden door.

Summary of the invention

Problems such as present high-quality natural timber resource is fewer and feweri in order to solve, solid wood flame treatment difficulty big, flame retardant effect is poor, cost height, and the use value that improves the low-quality fast growing wood, the utility model provides a kind of fire-proof wooden door that utilizes the flame-retardant veneer laminated making of fast growing wood.

The utility model is achieved through the following technical solutions:

A kind of flame-retardant veneer laminated fire-proof wooden door comprises doorframe, and described doorframe is made by fast growing wood is flame-retardant veneer laminated; The fiery face that is subjected at doorframe is pasted with PLASTIC LAMINATED, decorative plywood successively, has groove at doorframe inner surface and door leaf periphery contact position, is provided with the fire prevention expanding sealing strips in groove.
