Abstract
The invention relates to a fireproof door leaf and a manufacturing method thereof, in particular to a fireproof door leaf made of cast-in-situ fireproof material. The fireproof door leaf comprises two panels, a framework and inorganic gelled material for stuffing, wherein the inorganic gelled material is liquid and is in cast-in-place at one side of each panel to form a firing exposed panel and a fire unexposed panel; the framework is mounted between the sides of the two panels, at which the inorganic gelled material is cast; vesicant is added in the liquid inorganic gelled material to form frothy liquid inorganic gelled material which is in cast-in-place in a hollow space formed by the framework so as to form the fireproof insulation main body of the door leaf; and the door leaf after the casting is leveled by a pressure apparatus. The invention has the advantages that the fireproof door leaf is manufactured in cast-in-place, thereby avoiding the phenomena of cracks, uneven stuffing and uneven material mixing in the prior art; the framework is combined with the firing exposed panel and the fire unexposed panel together under the action of a hydrostatic press, thereby avoiding cracks generated by later stage stuffing or decoration; the framework is filled with the inorganic gelled material containing a great amount of foam, thereby lightening the weight of the whole fire door.
Description
Technical field
The present invention relates to a kind of building fire protection equipment, be specifically related to a kind of fireproof door leaf made of cast-in-situ fireproof and manufacture method thereof.
Background technology
At present in the structure of prior art fire-proof door leaf, there is employing to fill the mode of solid fireproof material in the hollow core flush door the inside, packing material generally is materials such as rock wool, expanded perlite, the fireproof door leaf that employing the method is made is prone to fill in uneven, various fire proofing mixing inequality, the hollow door leaf and is filled with space or dead angle, reduced the fire resistance of whole door leaf, even above-mentioned situation do not occur, the door leaf that adopts this kind method to make is whole fire-resistant not high yet, and fire resistance period is far below present new national standard.Also some adopts wood materials to make door leaf, earlier timber is soaked in the solution that fire proofing material is made, after treating certain hour, take out again and handle, make the door leaf keel frame that needs at last,, can not satisfy the requirement of fire-protection rating because the door leaf of this structure adopts wood materials too many, some in addition the wood materials at keel frame-saw place is not all coated, whole fireproof performance is lower than preceding a kind of door leaf.The position of other some door leaf different parts fire proofing material is provided with not ideal enough, and some has ignored the fire safety problem of each face junction of door leaf framework, becomes weak link and these places are the easiest when the condition of a fire takes place, and has destroyed the fireproof performance of whole fire-proof door leaf.
More than various door leafs generally attach one deck PLASTIC LAMINATED or decorative panel on its surface, the attaching mode adopts bonding, modes such as nail joint, the globality of door leaf is not good, its outer field PLASTIC LAMINATED also becomes a door leaf fireproof part, some slits just inevitably appear in the joining place of each face of door leaf framework like this, and these slits generally are to adopt fire proofing material, putty or coating tamps the slit, when the condition of a fire takes place when, slit place because material different and with labeled door be not that an integral body and refractoriness are far below other position, in case being broken through whole door leaf by fire will be because of the destroyed and whole flameproof effect that loses in part, adopt metal shell to make the framework fire prevention mode of the inside interpolation fire proofing then, its filler is cheap and easy to make, but after being heated, some material can adopt living poison gas, increased the weight of the harmfulness of fire on the contrary, and metal easily deforms after being heated, and loses efficacy thereby make labeled door produce distortion.
As my application number: the production method and the structure of 94246538.5 and 97238059.6 disclosed a kind of labeled doors, frame, adopt the mode of one deck fire prevention slurry layer of glass to form a clad on the door leaf two sides on the skeleton surface of door, frame, the middle skeleton of installing, the skeleton hollow part utilizes rock wool to fill up, flexible type not after the door leaf that the integral cast moulding forms thus is heated, and being added with bonding agent in the fire prevention slurry makes the PLASTIC LAMINATED of attaching of door leaf surface not easy to crack, fireproof performance and globality are fine, for China's fire-fighting has played good guaranteeing role.But inner the filling on an empty stomach adopted rock wool, makes reinforced materials with glass fiber in the PLASTIC LAMINATED, is not inconsistent the requirement of national GB12955-2008 new standard.Rock wool or aluminium silicate wool and all be solid with perlite etc., the workman is once careless manipulation, and door leaf leaves the space, can bring hidden fire-fighting danger.
The fire-proof door leaf that adopts all is that several sections sticks with glue, solid is filled at present, and steel nail anchor roped party is closed and formed, and does not make the fire-proof door leaf of the curing of the complete one of substance of whole door leaf formation, only is the one door leaf on the letter.
