Problems solved by technology

However, these materials are placed inside the door leaf structure as the door core, which will increase the weight of the door. In addition, some materials will be wasted. At the same time, these materials may have an impact on the environment and human health, and the most troublesome thing is if Filling these materials will increase the operational burden, that is, it is not convenient for processing and production

Embodiment Construction

[0047] The present invention will be further described below in conjunction with the accompanying drawings. The present invention can be single leaf door, also can be combination door.

[0048] Such as Figure 4 As shown, a wooden heat-insulated fire door is provided here, including a door leaf 1 and a door frame 2, and a fireproof lock 8 is installed on the door leaf 1.

[0049] Then the door leaf 1 includes a door leaf skeleton in terms of composition, and the formation of the door leaf skeleton includes the skeleton 7 arranged on both sides and the middle skeleton 10 provided between the skeleton 7, such as Figure 6 shown. And the glass magnesium inorganic fireproof board 5 is pressed on both sides of the door frame, and the outer surface of the glass magnesium inorganic fireproof board 5 is covered with a flame-retardant plywood 4, such as Figure 5 . The two sides of the door leaf 1 respectively form the fire-receiving surface and the back-fire surface. When conduct...

Abstract

The invention discloses a coreless wooden heat-insulating fireproof door, which comprises a door leaf and a door frame and is characterized in that: the door leaf comprises a door leaf framework; magnesium inorganic fireproof boards are pressed at the two ends of the door leaf framework; the external surfaces of the magnesium inorganic fireproof boards are covered by flame-retardant plywood boards; the two sides of the door leaf is respectively provided with a heated surface and an unexposed surface; the door leaf framework comprises frameworks arranged on left and right sides; middle frameworks are arranged between the frameworks; channels for airflow circulation are formed between the middle frameworks or among the middle frameworks and the frameworks on the two sides; a hollow shape is formed in the door leaf without filling any flame-retardant heat-insulating material; and upper and lower stiles of the door leaf are provided with vent holes opposite to the channel. The problems can be well solved; and the product can meet the requirements of fire insulation and fire integrity and can also meet the stipulations of the national standard.

Description

technical field [0001] The invention relates to the technical field of building doors, in particular to a coreless wooden heat-insulating fire-proof door that is not filled with any flame-retardant and heat-insulating materials and forms a hollow inside the door leaf. Background technique [0002] At present, for various types of buildings, with the improvement of national standards for fire doors, especially the demand for fire protection performance of high-rise buildings has been greatly improved, so fire doors are also gradually increasing. According to the survey, the internal structure of the more popular fire door products in the market is mostly filled with flame retardant and heat insulating materials. [0003] Among them, the Chinese patent with patent number 200620092997.9 introduces a fire door, such as figure 1 As shown, it includes a door frame and a door leaf set on the door frame through a movable door shaft; the middle of the door leaf is a flame-retardant ...
