Description

Fireproof lampshade

Technical Field

The utility model relates to a building fire-proof material technical field particularly, relates to a fireproof lamp shade.

Background

Ceiling suspended ceilings are used for more and more decoration in modern industry and civil buildings, and the arrangement of low-voltage energy-saving lamps on holes on the ceilings is a necessary trend; however, in case of fire, the flame may be discharged to the upper space of the ceiling through the installation hole of the low pressure electricity saving lamp, thereby forming a chimney effect, and the fire may be greatly increased, resulting in more damage. The fire-proof cover covers the transformer and the mounting hole of the low-voltage energy-saving lamp, so that the problem can be well solved. However, because the contact part between the existing fireproof cover and the ceiling is not tightly sealed, flame can come out, so that the temperature of the contact point between the fireproof cover and the ceiling is too high, and the fireproof heat insulation property is failed.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a fireproof lamp shade, the vertical inflation when fireproof mat receives the fire effectively keeps apart the clearance between flame and lamp shade and the ceiling.

In order to achieve the above object, the utility model adopts the following technical scheme:

the utility model provides a fireproof lampshade, includes that the toper covers and the fire prevention fills up, the toper covers the no ventilation hole, the fire prevention fill up set up in the bottom surface of toper cover, and the appearance that fills up of fire prevention agrees with the bottom surface of toper cover mutually, the center that fills up of fire prevention is provided with the mounting hole of lamps and lanterns, the fire prevention fills up and the toper cover is intumescent material.

The border of fire prevention pad is provided with the banding.

Preferably, the edge sealing is made of glass fiber cloth and aluminum foil.

Preferably, the edge seals are uniformly provided with broken slits.

The thickness of the fireproof cushion of the utility model is 4-6 mm.

The utility model has the advantages that:

1. the utility model discloses bottom surface at the fire prevention cover sets up the intumescent fire prevention pad, and the fire prevention pad is vertical inflation when receiving the fire, effectively keeps apart the clearance between flame and lamp shade and the ceiling, has stopped because the intensification at lamp shade and ceiling contact edge causes the fire prevention inefficacy.

2. The edge of the fireproof pad is provided with a sealing edge, and the material is effectively blocked at the inner side of the contact gap between the lampshade and the ceiling after expansion, so that the penetration of smoke can be completely isolated.

FIG. 3 is a schematic view of the expanded state of the fire resistant enclosure;

reference numerals: 1. a conical cover; 2. a fire protection mat; 3. a ceiling; 4. mounting holes; 5. sealing edges; 6. and (5) breaking the seam.

Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Example 1

As shown in figure 1, a fireproof lampshade comprises a conical cover 1 and a fireproof pad 2, wherein the conical cover 1 is not provided with a ventilation hole, the fireproof pad 2 is arranged on the bottom surface of the conical cover 1, the appearance of the fireproof pad 2 is matched with the bottom surface of the conical cover 1, the center of the fireproof pad 2 is provided with a mounting hole 4 of a lamp, and the fireproof pad 2 and the conical cover 1 are made of expansion materials.

The fire-proof principle is as follows: as shown in figure 2, the fireproof cushion 2 is arranged on the ceiling, the fireproof cushion 2 is arranged in the conical cover 1, the fireproof cushion 2 and the conical cover 1 expand when receiving high temperature, the flame and the gap between the lampshade and the ceiling are effectively isolated, the sealing effect and the heat insulation effect can be achieved, the temperature of an outside temperature measuring point cannot rise too fast, and the whole fireproof time is greatly prolonged.

Example 2

This example is based on example 1:

the edge of the fireproof pad 1 is provided with a sealing edge 5. The sealing edge is effectively sealed at the inner side of the contact gap between the conical cover and the ceiling after the material is expanded, and the penetration of smoke can be completely isolated.

The thickness of the fire protection mat 2 is 4 mm.

Example 3

This example is based on example 2:

the edge sealing 5 is made of glass fiber cloth and aluminum foil. The glass fiber cloth and aluminum foil composite material is a good fireproof material, and can improve the fire resistance limit of the lampshade from 30min to 120 min.

The thickness of the fire protection mat 2 is 6 mm.

Example 4

This example is based on example 2:

and the edge seals 5 are uniformly provided with broken slots 6. And a broken slot is torn on the sealed edge, so that the device is suitable for coating the arc-shaped edge, and the coating is more stable and tight.

The thickness of the fire protection mat 2 is 5 mm.

The utility model adopts the expansion material which is the conventional expansion materials such as expanded graphite, expanded perlite, expanded vermiculite, phosphorus-nitrogen expansion and the like which are expanded by heating.

The utility model discloses in the conventional connected mode such as not mentioning for screw thread, riveting, bonding, screw and welding.

The above-mentioned embodiments only express the specific embodiments of the present invention, and the description thereof is specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
