Abstract
The utility model discloses a buckling multi-functional special door, a steel door used in the building industry, which is characterized in that the door leaf of the door is buckled and bit together by a face plate and a back plate. The panel is respectively provided with a flanging on three sides; a female is pressed on the rim of the flanging; the back plate is also respectively provided with a flanging on three sides; a table is pressed on the surface of the flanging. The utility model has the advantages of welding spot free performance, flat and beautiful surface, firm and reliable door leaf plate, electric force and raw materials saving ability and low cost; in addition, the connection strength of biting is higher than the connection strength of the welding.
Description
The utility model relates to a kind of architectural used steel door
Steel protective door and steel security door have been used as the family door at present, are widely used in architectural.All adopt welding between the panel of existing double-deck steel door and the backboard and fuse.Therefore the solder joint of many scar shapes is left in the junction, and this not only diminishes the attractive in appearance of steel door.And for steel door is carried out surfacing, also will increase the man power and material these solder joints are polished, the cost cost is increased.The workman often can cause " dry joint " when welding in addition, makes the panel of steel door and the bonding strength of backboard not reach due requirement, can influence the quality of whole steel door.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and provides a kind of interface not have solder joint, and the junction is smooth attractive in appearance, the bonding strength height, and the door leaf plate is solid and reliable, the mouth biting type multifunctional special door that theftproof performance is strong.
The purpose of this utility model is to reach by following measure: the door leaf of this mouth biting type special door is made up of backboard and panel, wherein around panel or left and right, down tripartitely curved the flangings that become 90 degree with the panel face are arranged, and be suppressed with at the edge of each side's flanging section be "
" the button mother of shape; And around backboard or left and right, following tripartite curved flangings that become 90 degree with the backboard face that have, and on each side's flanging face, be suppressed with and be spaced, to convex, section be "
" coak of type.
The utility model can be between backboard and panel in, the safety grid made from steel bar is set.
The utility model can also be at the filling of the gap between backboard and panel polyphenyl alkene plastics expanded material in order to reach the effect of insulation, heat insulation, noise reduction.
The drawing of accompanying drawing is described as follows:
Fig. 1 is an outside drawing of the present utility model.
Fig. 2 is the right view of Fig. 1.
Fig. 3 is the stereogram of panel.
Fig. 4 is the stereogram of backboard.
Fig. 5 is the female section amplification figure of button.
Fig. 6 is the section amplification figure of coak.
The utility model is described in further detail below in conjunction with embodiment: the door leaf of the multi-functional steel special door of this mouth biting type is made up of panel (1) and backboard (2).Wherein left and right, following tripartite the bending at panel (1) has the flangings (1-3) that become 90 degree with panel face (1-1).And be suppressed with in the edge of each flanging (1-3) section be "
" the button mother (1-2) of shape.And backboard (2) left and right, down the three parts also curved have becomes 90 flangings (2-3) of spending with backboard face (2-1), and on the face of each flanging (2-3), be suppressed with and be spaced, to convex, section be "
" coak (2-2).Before panel (1) and backboard (2) snapping interlock, can between panel (1) and backboard (2), the intersecting parallels safety grid made from steel bar (4) be set in addition.When panel (1) and backboard (2) snapping interlock, be that the coak (2-2) on the backboard (2) is pressed into buckleing among the mother (1-2) on the panel (1), kill so the coak (2-2) on the backboard (2) can be gone up the barb of buckleing female (1-2) by panel (1).Panel (1) just is securely connected with backboard (2) and is integral like this.Constitute a complete door leaf.Then the filling of the gap between panel (1) and backboard (2) polyphenyl alkene plastics (3) is shut the top of door leaf afterwards, again door leaf is sent to foaming after, just become one fan no solder joint, interface smooth attractive in appearance, can eliminate the noise, heat insulation steel door leaf.
The utility model has following advantage compared to existing technology: this door leaf interface place does not have solder joint, and the surfacing of door leaf plate is attractive in appearance. The panel connection intensity height that interlock is connected with backboard can bear 6000 Ns pulling force, has greatly improved theftproof performance. And produce this kind mouth biting type steel door, and can also energy savings and material, production cost is reduced.
Claims (3)
1, a kind of mouth biting type multifunctional special door that constitutes door leaf by backboard (2) and panel (1), it is characterized in that around panel (1) or left and right, down tripartite curved have becomes 90 flangings (1-3) of spending with panel face (1-1), and be suppressed with at the edge of each side's flanging (1-3) section be "
" the button mother (1-2) of shape; And around backboard (2) or left and right, down tripartite curved have becomes 90 flangings (2-3) of spending with backboard face (2-1), and on the face of each side's flanging (2-3), be suppressed with and be spaced, to convex, section be "
" coak (2-2) of shape.
