Description

Fireproof door with smoke-proof structure

Technical Field

The utility model belongs to prevent fire door, in particular to prevent fire door with smoke protection structure.

Background

With the improvement of the fire protection consciousness of people, the residential fire door is more and more favored by people, but the conventional fire door is usually made of steel materials and can destroy the aesthetic feeling of interior decoration, so the wooden fire door using fire-resistant glass is gradually applied to the interior decoration. Because the thermal expansion coefficients of the fire-resistant glass and the fire-retardant wood are different, how to realize the reliable connection of the fire-resistant glass and the fire-retardant wood under various environmental conditions and effectively block smoke becomes a problem to be solved urgently.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a connect reliable, sealing performance is good prevent fire door with smoke prevention structure.

In order to achieve the above purpose, the utility model adopts the technical scheme that: the utility model provides a prevent fire door with smoke prevention structure, includes the deckle board, and the middle part of deckle board is equipped with the hole, and gasbag cladding fire-resistant glass's flange links to each other through spacing with the mounting panel of fixing on the deckle board, with fire-resistant glass centre gripping in the hole.

Compared with the prior art, the utility model discloses there are following technological effect: simple structure, when realizing the reliable connection of fire-resistant glass and door body frame plate, can also effectively promote the sealing performance of the two junction to reliably ensure user's personal safety.

Detailed Description

The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings 1-4.

A fireproof door with a smoke-proof structure comprises a frame plate 10, wherein a hole 11 is formed in the middle of the frame plate 10, and an air bag 30 covers the edge of a fireproof glass 20 and is connected with a mounting plate 12 fixed on the frame plate 10 through a limiting strip 13 to clamp the fireproof glass 20 in the hole 11. The air bag 30 with changeable shape is adopted to connect the transition fire-resistant glass 20 with the clamping piece and the frame plate 10, so that the breakage caused by the fact that the fire-resistant glass 20 is clamped by hard materials can be avoided, the sealing performance between the fire-resistant glass 20 and the air bag 30 and between the air bag 30 and the clamping piece can be greatly improved, and the fire-resistant and smoke-proof performance of the fire-proof door is ensured.

The air bag 30 surrounds the edge of the refractory glass 20 to make the connection between the refractory glass 20 and the frame plate 10 more reliable. The lining of the air bag 30 is made of high-temperature-resistant rubber or high-temperature-resistant silica gel, and the ceramic fiber cloth is sleeved outside the lining, so that the high-temperature resistance of the air bag 30 can be ensured, and the tightness of the air bag 30 can also be ensured.

The mounting plate 12 is fixed on the plate body of the frame plate 10 near the opening edge of the hole 11, the first decoration strip 14 made of flame-retardant wood is laid on the outer side of the mounting plate 12, the body 141 of the first decoration strip 14 is arranged to be attached to the outer plate surface of the mounting plate 12, the bottom of the body 141 extends inwards to form a platform 142 and is arranged at intervals with the fire-resistant glass 10, the upper table surface of the platform 142 is provided with a flat flame-retardant piece 143, and the flame-retardant piece 143 is arranged at intervals with the fire-resistant glass 10. The flame-retardant piece 143 is made of expandable graphite and is arranged separately from the fire-resistant glass 20 at normal temperature, and when the temperature rises, the flame-retardant piece 143 expands and contacts with the fire-resistant glass 20 to form surface sealing, so that the fire-resistant glass 20 is clamped, and the temperature in a connecting cavity formed by enclosing the first decorative strip 14, the frame plate 11 and the mounting plate 12 is effectively reduced.

In the embodiment, the limiting strips 13 are made of non-combustible materials, and the flexible fire retardant 21 is laid at the edge of the fire-resistant glass 20, so that the sealing performance of the joint is ensured, and the fire-resistant glass 20 is reliably clamped.

The top of the body 141 extends upwards and is connected with a second decoration strip 15 made of a flame-retardant material in a matching manner, the limiting strip 13 is made of a ceramic material, and the flexible flame retardant 21 is made of expandable graphite. The second molding 15 in this embodiment is made of flame-retardant wood.

Mounting panel 12 adopts elastic material to make, further promotes the centre gripping effect, and the bottom plate body of mounting panel 12 inwards extends and is the binding off form, avoids spacing 13 from the connection inefficacy that the landing leads to between two mounting panels 12.
