Technical Field

The utility model relates to a prevent fire door, especially a light high strength prevents fire door.

Background

A fire door is a door that can meet the requirements of fire stability, integrity and thermal insulation within a certain period of time. It is a fire-proof partition with certain fire resistance, which is arranged in fire-proof subareas, evacuation staircases, vertical shafts and the like. The fireproof door has the functions of a common door, has the functions of preventing the fire from spreading and the smoke from diffusing, and can prevent the fire from spreading within a certain time to ensure the evacuation of people. However, the existing fireproof door is heavy in weight and has a large burden on a door frame and a wall body, and the strength of the fireproof door is reduced due to different thermal expansion coefficients of various fillers used in the fireproof door.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a fire door is prevented to light high strength. It not only lightens prevents fire door weight, but also can ensure to prevent fire door intensity.

The utility model discloses a technical scheme: fire door is prevented to light high strength, including the door frame, the door frame passes through fire prevention hinge AND gate body coupling, is provided with the sealing strip on the fitting surface of the door frame and the door body, and the door body includes the steel shell body, is equipped with in the steel shell body to strengthen horizontal muscle and strengthens respectively one of indulging the muscle, strengthens horizontal muscle and strengthens to indulging and be provided with the fire prevention inner panel between the muscle.

Among the aforementioned fire door is prevented to light high strength, the fire prevention inner panel be the pearlite PLASTIC LAMINATED, the outside of pearlite PLASTIC LAMINATED is provided with the fire prevention plastic layer.

In the light-weight high-strength fireproof door, the fireproof inner plate is honeycomb-shaped.

In the aforementioned fire door is prevented to light high strength, the door frame include the door frame shell body, be provided with the fire prevention inner core in the door frame shell body.

Among the aforementioned fire door is prevented to light weight high strength, the door frame be provided with U type mouth with being connected of wall, the door frame shell body is steel material, the fire prevention inner core is pearlite fire prevention material.

Compared with the prior art, it can realize strengthening horizontal muscle and strengthening vertical muscle through setting up in the steel shell body of the door body, improves the intensity and the rigidity of preventing fire door, still makes to prevent that the fire door quality alleviates, reduces the burden to door frame and wall body, is strengthening horizontal muscle and is provided with the fire prevention inner panel with strengthening vertical between the muscle, and the fire prevention inner panel adopts honeycomb pearlite fire prevention material, improves and prevents fire door intensity, makes the security performance promote, the utility model discloses the structure is retrencied, and stable performance is difficult for the trouble.

Drawings

Fig. 1 is a schematic structural diagram of the present invention;

fig. 2 is a cross-sectional view of the present invention.

The labels in the figures are: 1-a door body, 2-a door frame, 11-a steel outer shell, 12-a reinforced transverse rib, 13-a reinforced longitudinal rib, 14-a fireproof inner plate, 15-a fireproof plastic layer, 21-a door frame outer shell, 22-a fireproof inner core, 3-a fireproof hinge and 4-a sealing strip.

Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

Examples are given. The light high-strength fireproof door comprises a door frame 2, wherein the door frame 2 is connected with a door body 1 through a fireproof hinge 3, a sealing strip 4 is arranged on a matching surface of the door frame 2 and the door body 1, the door body 1 comprises a steel outer shell 11, a reinforcing transverse rib 12 and a reinforcing longitudinal rib 13 are arranged in the steel outer shell 11, and a fireproof inner plate 14 is arranged between the reinforcing transverse rib 12 and the reinforcing longitudinal rib 13.

The fireproof inner plate 14 is a perlite fireproof plate, and a fireproof plastic layer 15 is arranged outside the perlite fireproof plate. The perlite fireproof plate 15 has the advantages of light weight, heat insulation, heat preservation, sound absorption and the like, but the perlite fireproof plate 15 is brittle, and the fireproof plastic layer 15 can reduce impact.

The fireproof inner plate 14 is honeycomb-shaped. The fireproof inner panel 14 in such a shape not only reduces the weight of the door body 1, but also has strong structural strength.

The door frame 2 comprises a door frame outer shell 21, and a fireproof inner core 22 is arranged in the door frame outer shell 21.

The connection face of the door frame 2 and the wall surface is provided with a U-shaped opening, the door frame outer shell 21 is made of steel materials, and the fireproof inner core 22 is made of perlite fireproof materials.

The utility model discloses a door frame 2. The door frame 2 is connected with the door body 1 through the fireproof hinge 3, the door body 1 comprises a steel outer shell 11, a reinforcing transverse rib 12 and a reinforcing longitudinal rib 13 are respectively arranged in the steel outer shell 11, the reinforcing transverse rib 12 and the reinforcing longitudinal rib 13 can reinforce the strength and rigidity of the fireproof door, can reduce the material consumption of the fire door, reduce the weight of the fire door, overcome the distortion of the fire door caused by uneven stress due to the thickness difference of the steel outer shell 11, arrange the fire-proof inner plate 14 between the reinforced transverse rib 12 and the reinforced longitudinal rib 13, the fire-proof inner plate 14 is a perlite fire-proof plate, the fire-proof inner plate 14 is filled in the steel outer shell 11 in a honeycomb shape, the weight of the fire-proof inner plate 14 is greatly reduced, and the strength of the honeycomb structure is high, the deflection is little under the condition of being heated, promotes the security performance of preventing fire door, and honeycomb still has the sound effect of inhaling, can reduce outdoor noise. But the pearlite PLASTIC LAMINATED is more fragile, the switch door probably destroys it at ordinary times, so the outside of pearlite PLASTIC LAMINATED is provided with fire prevention plastic layer 15, fire prevention plastic layer 15 reduces the collision impact of pearlite PLASTIC LAMINATED, fire prevention plastic layer 15 is to its guard action of pearlite PLASTIC LAMINATED, door frame 2 can be pre-buried among the wall body, can reduce the burden of preventing fire door to the wall body, door frame 2 is provided with U type mouth on the face of being connected with the wall body, when the installation, build at door frame 2 and accomplish the back, fill into cement in the U type mouth, make prevent fire door and wall form wholly, reliability and stability reinforcing. Be provided with sealing strip 4 on the fitting surface of door frame 2 and door body 1, sealing strip 4 is the fire prevention thermal expansion strip, and it can expand when meeting heat, can seal the gap between door body 1 and the door frame 2, prevents that the flue gas from getting into, promotes the security performance.
