Embodiment Construction
[0026] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0027] Such as figure 1 , a steel and wood fireproof door leaf with a metal skeleton embedded in the periphery of the single door leaf, including a skeleton forming the periphery of the door leaf. Fiberboards 1 are bonded to the front and rear sides of the skeleton with fireproof glue 4. The front side fiberboard 1 constitutes the door panel, and the rear side fiberboard 1 constitutes the door leaf backboard, and a cavity is formed between the fiberboards 1 on the front and rear sides and the skeleton, and the cavity is filled with fireproof foam filler 3. The skeleton is composed of a metal profile 7 and a fiberboard 1 bonded on the outside of the metal profile 7 with fireproof glue 4, an inner laminate 2, and a fiber block 6 on the side wall, and the metal profile 7 is bent toward the cavity with at least one concave groove , The concave groove is also filled with...

The invention provides a steel wooden fireproof door leaf with the rim internally embedded with a metal framework. The steel wooden fireproof door leaf comprises a framework forming four edges of the door leaf; fiber plates (1) are adhered at the front side and the back side of the framework by fireproof glue; the fiber plate (1) at the front side forms a door leaf panel; the fiber plate (1) at the back side forms a door leaf back plate; and a cavity is defined between the fiber plates (1) at the front side and the back side and the framework; and a fireproof foaming filler (3) is filled in the cavity. The steel wooden fireproof sash is characterized in that the framework consists of a metal structural section (7), the fiber plates (1) adhered at the outer side of the metal structural section (7) by fireproof glue, an inner side special layer board (2) and a fiber block (6); and the metal structural section (7) is at least bent towards a direction inwards the cavity, so as to form a concave groove. A wire gauze (5) parallel to faces of the fiber plates (1) is paved in the cavity; and the wire gauze (5) is covered in the fireproof foaming filler (3). The steel wooden fireproof door leaf is internally connected through welding connection at the connection part of the metal structural section (7).
Description
1. Technical field [0001] The invention relates to a fireproof door, in particular to a steel and wood fireproof door leaf with a metal framework embedded in the periphery of the door leaf, which is suitable for single-leaf fire-proof doors and double-leaf fire-proof doors (including mother and child type). 2. Background technology [0002] Most of the existing steel-wood fire doors use steel door frames, wooden door leaves, and wooden keel finger-joint board skeletons around the door leaf (the finger-joint boards are made of multiple wooden boards, and the upper and lower parts are no longer glued to the plywood. It adopts a jagged interface, which is similar to cross-jointed fingers of two hands, so it is called a finger-joint board), and the interior of the door leaf is filled with fire-resistant materials. [0003] Chinese patent application No. 200910131111.5 discloses a fireproof door leaf and a manufacturing method thereof, in particular to a fireproof door leaf of ca...
