Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example (b):

referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a fire door is prevented to high fire-retardant timber, is provided with clay layer 2 including door plant 1, the 1 outside of door plant, and the 2 outside of clay layer is provided with rubber layer 3, and the 3 outside on rubber layer is provided with weaves stratum reticulare 4, weaves the stratum reticulare 4 outside and is provided with

puigging

5, and 5 outside posts in the puigging has solid wood cortex 6, and the 6 outside of solid wood cortex is provided with first fire-retardant layer 7.

Specifically, one side of the sound insulation layer 5 close to the solid wood skin layer 6 is provided with a plurality of grooves 8. Through setting up recess 8, reduce puigging 5 and the area of contact of wood cortex 6, simultaneously because there is air in the recess 8, and the coefficient of thermal conductivity of air is low, through the aforesaid setting, has reduced heat transfer to on the puigging 5.

Specifically, a second flame-retardant layer 9 is arranged between the sound-proof layer 5 and the solid wood skin layer 6. The soundproof layer 5 is prevented from being ignited by providing the second flame retardant layer 9.

Specifically, the door panel 1 is composed of a first door panel 10, a second door panel 11 and a metal framework 12 arranged between the first door panel 10 and the second door panel 11, the first door panel 10 and the second door panel 11 are both composed of wood which is difficult to burn, and the metal framework 12 is formed by welding a cross rod 13 and a vertical rod 14 into a whole. Through the setting, increase door plant 1's structural strength, avoid door plant 1 to receive the striking back, door plant 1 is damaged, leads to the problem of fire prevention effect variation.

Specifically, fine sand 15 is arranged between the cross rod 13 and the vertical rod 14. When any one of the first door panel 10 and the second door panel 11 is ignited, the fine sand 15 flows out to bury a part of the flame, thereby reducing the fire.

One specific application of this embodiment is: door plant 1 is wrapped up by clay layer 2, makes door plant 1 isolated with the air, has avoided door plant 1 the problem of being lighted under the high temperature condition. Through setting up rubber layer 3 protection clay layer 2, prevent door plant 1 in normal use, clay layer 2 receives the impact and damaged problem. The problem of splashing after the clay layer 2 is damaged by large impact is prevented by arranging the woven net layer 4. The provision of the first fire retardant layer 7 avoids the problem of the solid wood skin 6 being ignited. Through setting up recess 8, reduce puigging 5 and the area of contact of wood cortex 6, simultaneously because there is air in the recess 8, and the coefficient of thermal conductivity of air is low, through the aforesaid setting, has reduced heat transfer to on the puigging 5.
