Description

A kind of stainless steel is double to open fire resistant doorsets

Technical field

The utility model relates to fire resistant doorsets for building, in particular to a kind of stainless steel is double to open fire resistant doorsets.

Background technique

Fire resistant doorsets are the fire resistant doorsets of fire resistance, and fire resistant doorsets can separate in space certain when fire occurs Valuable escape time is won in the sprawling of time inner tissue's intensity of a fire for the people.Fire resistant doorsets are extensively with applied to house, quotient This crowd density in the fields such as field, ship, workshop or warehouse, especially high residential building is big, needs the building of longer escape time, Fire resistant doorsets are even more the important ring ensured personal safety.

Existing market is the common fire resistant doorsets overwhelming majority for the fire resistant doorsets due to metal plate as door leaf, and main reason is golden Accessory has dystectic characteristic, and when fire occurs, door leaf the feelings of structure destruction will not occur in the short time due to heated Condition can stop the sprawling of the intensity of a fire.But it is higher and higher with skyscraper, people need necessary escape time also increasingly It is long, the requirement escaped enough cannot be only hidden from by the fire resistant doorsets fire resistance period that metal plate is constituted, it is now desired to a kind of fire resisting Time longer fire resistant doorsets.

Utility model content

The purpose of the utility model is to provide a kind of stainless steels pair to open fire resistant doorsets, has longer fire resistance period.

The above-mentioned technical purpose of the utility model has the technical scheme that

A kind of stainless steel is double to open fire resistant doorsets, including doorframe, and it is several to be equipped with articulated section at left and right sides of doorframe, in doorframe By articulated section rotation connection there are two door leaf, two door leafs are symmetrical set, and the door leaf includes two fireproof panels and swollen Swollen pearlite slab, the method that the two sides of the expanded pearlite rock beam passes through molding respectively are fixed with fireproof panel.

By using above-mentioned technical proposal, door leaf mainly undertakes the fire prevention task of fire resistant doorsets, and fireproof panel is mainly by fusing point High stainless steel plate is made, and has excellent fire resistance, can effectively hinder the sprawling of the intensity of a fire, while expanded pearlite rock beam matter Gently, heat-proof quality is excellent and flame retardant property is good, and expanded pearlite rock beam and fireproof panel mating reaction are conducive to extend fire prevention The fire resistance period of door.

Further, flame-retardant foam plate is fixedly connected between fireproof panel and expanded pearlite rock beam.

By using above-mentioned technical proposal, flame-retardant foam plate is due to further hindering with good fire-retardant and heat-proof quality Hinder heat to transmit from fireproof panel to expanded pearlite rock beam, is conducive to the fire resistance period for further increasing fire resistant doorsets.

Further, the method that flame-retardant foam plate is specifically fixedly connected is that flame-retardant foam plate is integrally formed by molding.

By using above-mentioned technical proposal, be conducive to improve the whole of flame-retardant foam plate and fireproof panel and expanded pearlite rock beam Body makes door leaf have better structural stability, will not recurring structure the case where deforming within the short time when heated when Occur.

Further, the side that door leaf stitches in is equipped with edge band, and edge band is arranged along the side length direction of door leaf.

By using above-mentioned technical proposal, edge band mainly possesses the gap for the side that sealing door leaf stitches in, avoids There is flame to enter in door leaf from the gap for the side that door leaf stitches in directly to burn door leaf inside.

Further, expansion adhesive tape is equipped between edge band and door leaf.

By using above-mentioned technical proposal, expands adhesive tape and be mainly used for increasing the leakproofness of edge band and door leaf junction Can, and expand adhesive tape it is heated after can expand filling chink, hinder fire and smoke spread.

Further, edge band is equipped with tread plate away from the one side of door leaf.

By using above-mentioned technical proposal, tread plate is mainly used for increasing the frictional force between two door leafs, avoids not having It will appear the case where fire resistant doorsets are opened in the case where having external force, while door leaf stitches in reduction fire resistant doorsets in the state of closing Gap reduces flue gas to a certain extent and passes through fire resistant doorsets.

Further, tread plate surface is provided with wavy anti-skid chequer.

By using above-mentioned technical proposal, the degree of roughness on the surface of tread plate is further increased, that is, is conducive to improve anti- The frictional resistance of draw runner.

Further, bound edge is provided on doorframe, the bound edge is located remotely from articulated section one side.

By using above-mentioned technical proposal, bound edge is made of stainless steel plate, on the one hand bound edge is used to protect doorframe, another party Bread side also strengthens doorframe.

Further, there are gap between bound edge and door leaf, the bound edge is fixedly connected with sealing rubber by fixing bolt Adhesive tape, the sealing rubber strip offset with door leaf surface.

By using above-mentioned technical proposal, door leaf and bound edge during switch gate is avoided to occur directly to hit, and Sealing rubber strip can also effectively absorb impact.

Further, the inside of doorframe be equipped with grouting chamber, the grouting chamber along doorframe direction be arranged, the grouting chamber with far It is inserted with crossbeam from the ground and in cavity parallel to the ground.

By using above-mentioned technical proposal, injection concrete makes doorframe wall be securely attached to one in grouting chamber It rises, since the top margin of doorframe is the position for being easiest to occur bending and deformation, so being arranged using wooden crossbeam instead of concrete Have in grouting chamber, crossbeam light weight itself will not cause excessive burden to doorframe.

In conclusion the utility model has the following beneficial effects:

1. having good fire resistance, the effective sprawling for hindering the intensity of a fire extends the fire resistance period of fire resistant doorsets；

2. there is outstanding sealing performance, the effective sprawling for hindering flue gas；

3. having good structural stability, makes fire resistant doorsets when fire occurs, it is broken will not to occur structure in the short time Bad situation.
