Description

A kind of fire-proof door leaf

Technical field

The utility model is mainly concerned with the fire protection equipment field, refers in particular to a kind of fire-proof door leaf.

Background technology

Traditional fire-proof wooden door fan main feature is: in the PLASTIC LAMINATED that anti-flaming thermal-insulation is housed on the counter-fire face of the wooden door leaf of fire retardant immersion treatment, and a pair of refractory slab suitable distance of being separated by; The anti-flaming thermal-insulation material is located at skeleton frame inside, after fire takes place, can stop penetrating of flame effectively, realizes fire prevention.The anti-flaming thermal-insulation material generally has two classes: a class is an aluminium silicate wool, adopts the higher processing technology of this type of material requirements, wayward quality, and fireproof performance is poor, is difficult to produce in enormous quantities; Another kind of is perlite or vermiculite material, and this type of material need adopt glue bonding, and it is very big to conduct oneself with dignity, and installation difficulty is big, and the long-term back of using is fragile.

The utility model content

The technical problems to be solved in the utility model just is: at the problem that prior art exists, the utility model provide a kind of simple and compact for structure, can reduce the prevent fires fire-proof door leaf of reliability of whole door weight and raising.

For solving the problems of the technologies described above, the solution that the utility model proposes is: a kind of fire-proof door leaf, it comprises the door leaf body of being made up of outside framework and inner frame, inner frame comprises and is embedded in the outside framework and is in length and breadth the interior moulding of arranging, the external surface of described door leaf body is coated with the fireproof panel layer, it is characterized in that: be provided with anti-flaming thermal-insulation layer and radiation proof layer of cloth between described fireproof panel layer and the interior moulding.

Described anti-flaming thermal-insulation layer is between radiation proof layer of cloth and fireproof panel layer.

Described fireproof panel layer is made up of PLASTIC LAMINATED and housing fireprotection layer, and the housing fireprotection layer is sheathed on the corner portion of outside framework, and PLASTIC LAMINATED is covered on the external surface of outside framework and inner frame and is embedded between the housing fireprotection layer.

Described radiation proof layer of cloth adopts the glass fiber aluminium foil cloth.

Described anti-flaming thermal-insulation layer adopts ceramic fiber blanket or ceramic fiber cloth or asbestos cloth or rock cotton board.

Compared with prior art, advantage of the present utility model just is:

1, fire-proof door leaf of the present utility model is simple and compact for structure, by anti-flaming thermal-insulation layer and radiation proof layer of cloth are set between interior moulding and fireproof panel layer, can improve the fire prevention reliability of whole door, can also reduce whole door weight;

2, fire-proof door leaf of the present utility model can be adjusted the fire resistance rating of door leaf according to actual needs, and is easy for installation, quick, can satisfy the needs in different markets, improved its compliance;

3, fire-proof door leaf of the present utility model, the fireproof panel layer adopts fabricated structure, has effectively solved monolithic construction and has fixed problem insecure, that come off easily, and then put forward its reliability;

4, fire-proof door leaf of the present utility model, the fireproof panel layer adopts fabricated structure, and anti-flaming thermal-insulation layer and Antiradiation protection cloth are ripe bulk article, and the quality of production is controlled in buying easily easily, especially is suitable for producing in batches.

The specific embodiment

Below with reference to the drawings and specific embodiments the utility model is described in further details.

Embodiment 1: as depicted in figs. 1 and 2, a kind of fire-proof door leaf of the present utility model, it comprises the door leaf body of being made up of outside framework 1 and inner frame 23, and inner frame 2 comprises and be embedded in the outside framework 1 and be in length and breadth the interior moulding of arranging 5, be latticed in moulding 5 be integral with outside framework 1 joggle.The external surface of door leaf body 3 is coated with fireproof panel layer 9, and fireproof panel layer 9 can also can adopt the combined type design for being coated on the whole plate of door leaf body 3 external surfaces.Referring to shown in Figure 2, fireproof panel layer 9 is made up of PLASTIC LAMINATED 4 and housing fireprotection layer 10, housing fireprotection layer 10 is sheathed on the corner portion of outside framework 1, PLASTIC LAMINATED 4 is covered on the external surface of outside framework 1 and inner frame 2 and is embedded between the housing fireprotection layer 10, housing fireprotection layer 10 can one process with the corner portion of outside framework 1, also can make fireproof panel layer 9 by screw or nailing and 3 whole connections of door leaf body.Between the fireproof panel layer 9 of door leaf body 3 one sides and interior moulding 5, be provided with anti-flaming thermal-insulation layer 7 and radiation proof layer of cloth 8, anti-flaming thermal-insulation layer 7 is adhered on the inwall of fireproof panel layer 9 by fire prevention glue or water glass, also can press and be located on fireproof panel layer 9 inwall by interior moulding 5, radiation proof layer of cloth 8 adopts the glass fiber aluminium foil cloth, anti-flaming thermal-insulation layer 7 can adopt ceramic fiber blanket or anti-flaming thermal-insulation materials such as ceramic fiber cloth or asbestos cloth or rock cotton board, and anti-flaming thermal-insulation layer 7 is between radiation proof layer of cloth 8 and fireproof panel layer 9.Anti-flaming thermal-insulation layer 7 and radiation proof layer of cloth 8 are generally positioned at the counter-fire face of door leaf body 3, play fire-retardant, heat insulation, radiation-resistant effect.

Embodiment 2: as shown in figures 1 and 3, present embodiment is identical with the basic structure of embodiment 1, difference from Example 1 is: according to the needs of fire-protection rating, the utility model can be further between the fireproof panel layer 9 of door leaf body 3 both sides and interior moulding 5, being equipped with anti-flaming thermal-insulation layer 7 and radiation proof layer of cloth 8, anti-flaming thermal-insulation layer 7 is adhered on the inwall of fireproof panel layer 9 by fire prevention glue or water glass, also can press and be located on fireproof panel layer 9 inwall by interior moulding 5, radiation proof layer of cloth 8 adopts the glass fiber aluminium foil cloth, and anti-flaming thermal-insulation layer 7 can adopt ceramic fiber blanket or anti-flaming thermal-insulation materials such as ceramic fiber cloth or asbestos cloth or rock cotton board.Anti-flaming thermal-insulation layer 7 is between radiation proof layer of cloth 8 and fireproof panel layer 9.Like this, anti-flaming thermal-insulation layer 7 and radiation proof layer of cloth 8 are arranged at the counter-fire face of door leaf body 3 simultaneously or carry on the back fiery face, and then can improve its fire endurance greatly, because door leaf body 3 by fire-retardant, heat insulation and radiation proof protection, can also effectively raise the integrality of door leaf body 3.
