Abstract

The utility model provides a novel fireproof door core board, belongs to and prevents fire door technical field. The utility model provides a bulk strength, anti twisting strength and antidetonation, the novel fireproof door core board that anti -collision performance is high. The utility model discloses a door core main part, pre -buried in door core main part have a structural steel skeleton, its characteristics are door core main part comprises three -layer fire prevention filling layer, and the intermediate level of three -layer fire prevention filling layer is the low -density filling layer, and its both sides are the high density filling layer respectively, low -density filling layer adoption unit weight is 240~300kgm3's pearlite PLASTIC LAMINATED, and the high density filling layer adopts unit weight to be 450~600kgm3's pearlite PLASTIC LAMINATED.

Description

A kind of Novel fire-proof door central layer

Technical field

This utility model belongs to fire resistant doorsets technical field, particularly relates to a kind of Novel fire-proof door central layer.

Background technology

At present, existing anti-fire door core board mostly use same density packing material fill form, bulk strength, anti-twist by force Degree and antidetonation, impact resistance intensity are the most inadequate, it is impossible to meet and use requirement.

Utility model content

The problem existed for prior art, this utility model provides a kind of bulk strength, anti-buckling strength and antidetonation, crashworthiness The Novel fire-proof door central layer that hit intensity is high.

To achieve these goals, this utility model adopts the following technical scheme that a kind of Novel fire-proof door central layer, including door panel Main body, is embedded with structural steel skeleton in door panel main body；It is characterized in that described door panel main body is made up of three layers of fire prevention packed layer, The intermediate layer of three layers of fire prevention packed layer is low-density packed layer, and its both sides are respectively high density packed layer；Described low-density packed layer Using unit weight is 240～300kg/m³Perlite fireproof plate, high density packed layer use unit weight be 450～600kg/m³Margarita Rock PLASTIC LAMINATED.

Described low-density packed layer uses unit weight to be 240kg/m³Perlite fireproof plate.

Described high density packed layer uses unit weight to be 450kg/m³Perlite fireproof plate.

The beneficial effects of the utility model:

1, anti-fire door core board bulk strength of the present utility model is strengthened, and anti-buckling strength and antidetonation, impact resistance intensity are bigger, Adapt to the place that blast is bigger；

2, anti-fire door core board fire resistance of the present utility model is more preferable；

3, anti-fire door core board of the present utility model is easy to process, the most too much increases production cost, but performance is largely increased, carry The high cost performance of product.

Accompanying drawing explanation

Fig. 1 is the structural representation of anti-fire door core board of the present utility model；

Fig. 2 is the longitudinal sectional view of Fig. 1；

Fig. 3 is the transverse sectional view of Fig. 1；

In figure: 1-door panel main body, 2-structural steel skeleton, 3-high density packed layer, 4-low-density packed layer.

Detailed description of the invention

With specific embodiment, this utility model is described in further detail below in conjunction with the accompanying drawings.

As shown in FIG. 1 to 3, a kind of Novel fire-proof door central layer, including door panel main body 1, it is embedded with in door panel main body 1 Structural steel skeleton 2；Described door panel main body 1 is made up of three layers of fire prevention packed layer, and the intermediate layer of three layers of fire prevention packed layer is low close Degree packed layer 4, its both sides are respectively high density packed layer 3；Described low-density packed layer 4 uses unit weight to be 240kg/m³Margarita Rock PLASTIC LAMINATED, high density packed layer 3 uses unit weight to be 450kg/m³Perlite fireproof plate.

Anti-fire door core board of the present utility model uses entirety to record and forms, and door panel main body 1 is seamless, and fire resistance is more preferable.

Claims

1. a Novel fire-proof door central layer, including door panel main body, is embedded with structural steel skeleton in door panel main body；Its feature Being that described door panel main body is made up of three layers of fire prevention packed layer, the intermediate layer of three layers of fire prevention packed layer is low-density packed layer, its Both sides are respectively high density packed layer；Described low-density packed layer uses unit weight to be 240～300kg/m³Perlite fireproof plate, high Density packed layer uses unit weight to be 450～600kg/m³Perlite fireproof plate.
