The utility model relates to a fire door which comprises a door frame, a door leaf and a fireproof hinge, wherein the door leaf is mounted on the door frame through the fireproof hinge, a fireproof lock and a door closer are arranged on the door leaf, the door leaf comprises a framework, a panel is arranged at the each of the two sides of the framework, fireproof plates are arranged among the framework and the panels, a cavity is defined by the panels and the framework, and perlite is filled in the cavity. The fire door is characterized in that a plurality of through holes are formed on the framework, and the door leaf is shaped through a hot pressing method. The fire door has the advantages that the structure is simple, moisture in a door core can be exhausted in time in the production process, so as to obtain the fire door with good quality, low cost and excellent fireproof property; simultaneously, the production efficiency is improved, and the problems of complex technology and consumption of long time in the prior art are solved.
Description
Technical field
The utility model relates to a kind of door that is installed on the building, particularly a kind of door with fire-proof function.
Background technology
Labeled door is fire prevention, Smoke prevention, play the critical facility of partition effect.At present, wooden heat-insulating fireproof door adopts expanded perlite, magnesia, magnesium chloride to mix as inserts, colds pressing, after passing through one week of air dry then, carry out the facing plate and condense, its weak point is: the hardness deficiency, in transportation, damage more; The moisture of door in-core can't be drained, and causes the facing plate to come off; Do not reach the requirement of anti-folding and anti-pressing; Inherent door core moisture does not take off dried, causes the proportion of door leaf to rise, and is carrying and is installing and make troubles; The cost height owing to cold pressing that this is specific, cause take a lot of work, time-consuming, a door core compacting is finished to need to divide and is colded pressing for three times, wherein at every turn more than 48 hours, the labor life is lost money.Owing to numerous and diverse technology, can't guarantee the needs of engineering.Based on above-mentioned situation, how to provide a kind of and enhance productivity, cost is low, fire resistance is excellent, the measured labeled door of matter, becomes the important topic of those skilled in the art's research.
Summary of the invention
The purpose of this utility model has provided a kind of simple in structure, production efficiency, cost is low, fire resistance is excellent, the measured labeled door of matter, has solved the deficiencies in the prior art part.
The purpose of this utility model is achieved in that a kind of labeled door, comprise: doorframe, door leaf and fire prevention hinge, door leaf is installed on the doorframe by the fire prevention hinge, door leaf is provided with Fire-proof lock and door closer, described door leaf comprises skeleton, the both sides of skeleton are respectively equipped with a panel, between skeleton and panel, be provided with PLASTIC LAMINATED, described panel and skeleton surround a cavity, fill perlite door core material in the cavity, it is characterized in that: several through holes are arranged, the door leaf method moulding of hot pressing on the described skeleton.
The granular size of described perlite door core material is 4-6mm.
Described perlite and panel hot pressing glue cementation.
The material of described skeleton is a pine.
Described panel is the Liu An clamping plate.
The fire proof seal bar is arranged between described door leaf and the doorframe.
The utility model has the advantages that: simple in structure, the moisture of door in-core can be discharged from process of production in time, and it is good to obtain quality, cost is low, the labeled door that fire resistance is excellent, simultaneously, improve the efficient of producing, solved prior art processes complexity, time-consuming problem.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is an A-A of the present utility model sectional view along the line.
Accompanying drawing 3 is a B-B of the present utility model sectional view along the line.
Accompanying drawing 4 is a C-C of the present utility model sectional view along the line.
Below in conjunction with drawings and Examples the utility model is elaborated.
The specific embodiment
Fig. 1 is in Fig. 4, a kind of labeled door, comprise: doorframe 1, door leaf 3 and fire prevention hinge 5, door leaf 3 is installed on the doorframe 1 by fire prevention hinge 5, door leaf 3 is provided with Fire-proof lock 4 and door closer 2, described door leaf 3 comprises skeleton 10, the both sides of skeleton 10 are respectively equipped with a panel, between skeleton 10 and panel 9, be provided with PLASTIC LAMINATED 7, described panel 9 and skeleton 10 surround a cavity, fill perlite door core material 8 in the cavity, it is characterized in that: several through holes 12 are arranged, the method moulding of door leaf 3 usefulness hot pressing on the described skeleton 10.
Described perlitic door core material particles size is 4-6mm, and the pulling force deficiency as after it solidifies less than this specification does not reach the resistance to compression standard simultaneously, and increases the unit weight of door leaf.
Described perlite door core material 8 and panel 9 usefulness hot pressing glue cementations.
The material of described skeleton 10 is a pine.
Described panel 9 is the Liu An clamping plate.
Between described door leaf 3 and the doorframe 1 fire proof seal bar 6 is arranged.
In order to accelerate drying, dehydration, prevent the door leaf distortion, on door leaf skeleton, burrow, intert in door leaf skeleton, wait and fill in perlite in the skeleton with the 14mm round steel, deliver to and start press on the hot press, extract round steel after the compacting out, from circular hole, spray, solved that door core moisture does not take off dried problem in the prior art through the moisture content of an in-core of heating, and since door leaf taken off dried, so the solid hard of door leaf.Since carry out puncturing technique, in light weight for this core can not be out of shape, convenient in carrying.Hot pressing through 40 minutes, door leaf promptly can be sawed door with regard to one-shot forming after the cooling, per 40 minutes big door leafs are 10 fans, and little door leaf is 20 fans not, and the facing plate on door leaf once presses simultaneously, so panel is very firm with the bonding of door core, has improved production efficiency.During hot pressing, select heat conducting oil boiler for use, dispose 10 layers hot press with oil circulation again and suppress, press temperature reaches 180 ℃, get final product through 40 minutes, and cost and time that a hot pressing need three cold moudlings than originally are much smaller.
The utility model is being up to the standards by state functionaries, successively provide 1200 door frames for medical equipment city, PVG, good garden, Anqing Shanghai 1600 door frames, admirable virtue garden, Shanghai 3900 door frames, the good garden of Golconda housing for survivor 56000 door frames are underway, Jiaxing is with square garden 1900 door frame labeled doors, and market is increasing to demand of the present utility model.
Below only expressed embodiment of the present utility model, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model patent scope.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
The utility model has the advantages that: simple in structure, the moisture of door in-core can be discharged from process of production in time, and it is good to obtain quality, cost is low, the labeled door that fire resistance is excellent, simultaneously, improve the efficient of producing, solved prior art processes complexity, time-consuming problem.
