Abstract

The utility model provides a novel fireproof door core board, includes the core body, be equipped with fire -retardant hole on the core body, fire -retardant hole is including positive fire -retardant hole and the fire -retardant hole in the back, openly fire -retardant hole sets up the front of core body, the fire -retardant hole in the back sets up the back of core body, openly fire -retardant hole with the fire -retardant hole -Offset in the back, fire -retardant hole is the fire -retardant hole of flute type. The utility model provides a novel fireproof door core board that the cost is lower, flame retardant efficiency is better.

Description

Novel fire-proof door central layer
Technical field
The utility model relates to labeled door field, especially a kind of Novel fire-proof door central layer.
Background technology
The general flame retardant effect of existing anti-fire door core board is bad, and the usual complex structure of good flame retardation effect, while waste material also not environmentally.
Summary of the invention
In order to overcome the deficiency that existing anti-fire door core board exists, the utility model provides that a kind of cost is lower, the good Novel fire-proof door central layer of flame retardant effect.
The utility model solves the technical scheme that its technical problem adopts:
A kind of Novel fire-proof door central layer, comprise central layer body, described central layer body is provided with fire-retardant hole, described fire-retardant hole comprises the fire-retardant hole in fire-retardant hole, front and the back side, fire-retardant hole, described front is arranged on the front of described central layer body, fire-retardant hole, the described back side is arranged on the back side of described central layer body, and the fire-retardant hole in fire-retardant hole, described front and the described back side misplaces and arranges, described fire-retardant hole is the fire-retardant hole of corrugated type.
Further, the front being arranged in described central layer body in column, fire-retardant hole, described front, fire-retardant hole, described front is provided with more than two row, and the fire-retardant holes, front of adjacent two row all misplace layout.
Further again, the back side being arranged in described central layer body in column, fire-retardant hole, the described back side, fire-retardant hole, the described back side is provided with more than two row, and the fire-retardant holes, the back side of adjacent two row all misplace layout.
The beneficial effects of the utility model are mainly manifested in: flame retardant effect is better, reduces burning velocity, extends burning time, be convenient to have the sufficient time to succour; While saving material, the thickness of plate is guaranteed.
Accompanying drawing explanation
Fig. 1 is the Facad structure schematic diagram of Novel fire-proof door central layer.
Fig. 2 is the inverse layer structure schematic diagram of Novel fire-proof door central layer.
Fig. 3 is the C-C sectional drawing of Fig. 2.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
With reference to Fig. 1 ~ Fig. 3, a kind of Novel fire-proof door central layer, comprise central layer body 1, described central layer body 1 is provided with fire-retardant hole, described fire-retardant hole comprises the fire-retardant hole 4 in fire-retardant hole, front 3 and the back side, and fire-retardant hole, described front 3 is arranged on the front 11 of described central layer body 1, and fire-retardant hole, the described back side 4 is arranged on the back side 12 of described central layer body 1, fire-retardant hole, described front 3 and fire-retardant hole 4, the described back side misplace and arrange, described fire-retardant hole is the fire-retardant hole of corrugated type.
Further, the front 11 being arranged in described central layer body 1 in column, fire-retardant hole, described front 3, fire-retardant hole 3, described front is provided with more than two row, and the fire-retardant holes, front of adjacent two row all misplace layout.
Further again, the back side 12 being arranged in described central layer body 1 in column, fire-retardant hole, the described back side 4, fire-retardant hole 4, the described back side is provided with more than two row, and the fire-retardant holes, the back side of adjacent two row all misplace layout.
In the present embodiment, outwardly, the left and right width in the fire-retardant hole of corrugated type is slightly larger than the thickness of central layer body 1 for the opening in the fire-retardant hole of corrugated type; Fire-retardant hole 3, described front often arranges and is provided with seven, and fire-retardant hole 4, the described back side often arranges and is provided with six.
The utility model, owing to being provided with the fire-retardant hole of corrugated type on central layer body 1, when central layer body 1 catches fire, due to the design in the fire-retardant hole of corrugated type, thus can delaying the burning velocity of fire, be convenient to rescue, also save material simultaneously.
