Abstract
The utility model discloses a kind of door leafs for having heat-insulated slot structure for high insulated fire entry door, it includes door leaf foreboard, door leaf backboard and the both side plate between the door leaf foreboard, door leaf backboard, and the end plate for closing door leaf both ends, side plate bending described in two sides is stamped with a step, and on the step surface of the step punch forming have it is multiple be spaced apart after be in bridge cutoff structure heat dam；The door leaf foreboard, side plate, door leaf backboard, another side plate successively fix the back wall strip door leaf ontology T-shaped at cross section.Door leaf in the utility model, by the setting of heat dam, improves heat-insulated, thermal insulation property in the case where existing door leaf thickness, weight are constant as much as possible, for high temperature fire prevention entry door.
Description
Technical field
The utility model relates to a kind of high temperature fire prevention entry doors, specifically, being related to a kind of for high temperature fire prevention entry door
Has the door leaf of heat-insulated slot structure.
Background technique
The door leaf for entry door of preventing fires is that thermal insulation material is filled inside door leaf to realize heat-insulated, heat preservation effect in the market
Fruit is usually the thickness by increasing door leaf, increases the thickness of the thermal insulation material of filling to increase at present in order to increase heat insulation effect
Add heat insulation effect, but not only increases door leaf steel plate materials after increasing thickness, fills out the consumption of core material, but also increase door leaf
Weight, increase the labor intensity of processing staff, installation personnel.
Summary of the invention
The purpose of this utility model is to provide one kind in the case where existing door leaf thickness, door leaf weight are constant, to the greatest extent may be used
Door leaf of the high heat-insulated, thermal insulation property of energy for high temperature fire prevention entry door, belongs to a kind of energy-saving doors, plays a part of to obstruct heat transfer.
In the utility model a kind of door leaf for having heat-insulated slot structure for high insulated fire entry door include door leaf foreboard,
Door leaf backboard and the both side plate between the door leaf foreboard, door leaf backboard, and the end plate for closing door leaf both ends, two
It is in bridge cut-off after side plate bending described in side is stamped with a step, and punch forming has multiple be spaced apart on the step surface of the step
The heat dam of structure；The door leaf foreboard, side plate, door leaf backboard, another side plate successively fix the back wall length T-shaped at cross section
Strip door leaf ontology.
All heat dams are distributed along strip door leaf ontology, are located along the same line, heat-insulated described in each adjacent two
The distance being spaced between slot is 20-50mm.
The distance being spaced between the two neighboring heat dam is 30mm.
The door leaf foreboard, door leaf backboard are fixedly connected with the plate-side plate welding.
Door leaf in the utility model is in the case where existing door leaf thickness, amount are constant, by heat-insulated on side plate and side
The setting of slot improves heat-insulated, thermal insulation property as much as possible.
Detailed description of the invention
Fig. 1 is the schematic front view of door leaf in the utility model.
Fig. 2 is the lateral schematic cross-sectional view of door leaf in the utility model.
Specific embodiment
It elaborates below in conjunction with attached drawing to the specific embodiment of the utility model.
As depicted in figs. 1 and 2, the door leaf in the utility model for high temperature fire prevention entry door is by zinc-plated cold-rolling steel-plate punch
Molding, includes door leaf foreboard 1, door leaf backboard 2 and two blocks of side plates 3, and the end plate for closing door leaf both ends (does not show in figure
Out), two pieces of symmetrical bendings of side plate 3 are stamped with a step 4, and punch forming has multiple be spaced apart on the step surface of step 4
It is afterwards in the heat dam 5 of bridge cutoff structure；Door leaf foreboard 1, side plate 3, door leaf backboard 2 and another side plate 3 surround all round closure, two
Hold open strip structure, i.e. door leaf ontology.Thermal insulation material is filled in door leaf body interior.All heat dams 5 are along door leaf
The longitudinal direction of ontology is located along the same line, and the bore size of each heat dam 5 is 200mm × 2mm, two neighboring heat-insulated
Spacing distance between slot 5 is 20-50mm, preferably 30mm, forms the bridge cutoff structure between door leaf foreboard 1, door leaf backboard 2,
Heat is effectively prevented, to the transmitting of door leaf foreboard 1, to play the role of heat-insulated, heat preservation from door leaf backboard 2.
The 4 outer surface adhesive seal item of step formed simultaneously in door leaf both side plate 3 guarantees can have while door leaf appearance
Effect prevents the heat between door leaf and doorframe between gap from conducting.
Claims (4)
