Abstract

The utility model relates to an aluminum-plastic composite thermal insulation side-hung leaf door, which at least comprises a fixed door frame and movable door leaves which are hinged on the fixed door frame through a hinge. The inner side of the door frame is fixedly provided with a cross arm and the inner sides of the door leaves are fixedly provided with middle pits; the right angle edges between the door frame and the door leaves is spliced with a 45 degree angle through plug-in; the two ends of the cross arm and the middle pits are respectively and vertically spliced in the inner sides of the door frame and the door leaves. According to the design, the utility model has the advantages of high intensity, good thermal insulation performance, economic efficiency and practicability; at the same time, the utility model has a plurality of colors with good lighting so as to satisfy the building mating of high, middle and low ranges, substantially having economic benefit.

Description

The disconnected plastic-aluminum combined insulation vertical hinged door of cold bridge

Technical field:

The utility model relates to a kind of insulation vertical hinged door, the plastic-aluminum combined insulation vertical hinged door of disconnected cold bridge that especially a kind of lighting performance is good, heat runs off less, cost is low, and it belongs to building construction and uses product manufacturing technology field.

Background technology:

Housing industry is in door and window is selected for use in recent years, and the kind of heat insulation window is more, and plastic-steel window, the plastic-aluminum combined heat insulation window of different series all can be selected for use, and the more building that satisfies different class of kind is installed and selected for use.At present the kind of door is few, the northern area of China winter climate cold particularly, and the lowest temperature reaches subzero 30 ℃-40 ℃.The kind of door is seldom removed floor spring door, security door Solid Door and general type aluminium alloy door in building construction for many years, the shortage of insulation kind.Particularly the business hall door requires lighting performance good, and good heat preservation performance elegant in appearance does not still have good thermal insulation door at present, have to replace with floor spring door, and this heat-insulating property is poor, heat runs off greatly, energy-saving effect is bad.Warming winter for the severe cold that solves northern area, most business hall have to add a bed thickness translucent plastic bar formula door curtain in the door of the Room, install two layers of door additional, prevents that heat runs off; But the inconvenience that has caused people to come in and go out has increased cost, and heat insulation effect is very undesirable simultaneously.

Summary of the invention:

The purpose of this utility model is at the deficiencies in the prior art, the plastic-aluminum combined insulation vertical hinged door of disconnected cold bridge that provide a kind of sound construction, cost is low, optical property good, the heat loss is few.

The purpose of this utility model is achieved in that

The plastic-aluminum combined insulation vertical hinged door of a kind of disconnected cold bridge which comprises at least fixedly doorframe, swing leaf, and swing leaf is hinged on fixedly on the doorframe by hinge; The doorframe inboard is installed with cross-arm, and the door leaf inboard is installed with middle bank; The mutual right-angle side connected vertically of doorframe and door leaf is 45 by plug-in unit pegs graft, and cross-arm and Zhong Kan two ends are by vertical respectively doorframe and the door leaf inboard of being plugged on of plug-in unit.

Also can be equiped with pushing-type or pull-type door closer on the doorframe.

Door leaf is laterally opened or the opposite opened door leaf, is equiped with stile in the vacation at least one side door fan of opposite opened door leaf.

Further, two surfaces, medial and lateral of doorframe and door leaf are equiped with the aluminium alloy extrusions that has cavity, and hidden parts is the disconnected cold bridge of multi-cavity that PVC plastics dovetail type is rolled into firm one in the middle of it.

According to above-mentioned design, the utlity model has high strength, good heat preservation performance, economical and practical advantage; Its color is various simultaneously, daylighting is good, and it is supporting to satisfy high, medium and low shelves building, the substantial evidence whole economic efficiency.

The specific embodiment:

With reference to the accompanying drawings the utility model is described below:

As shown in Figure 1, the utility model doorframe 1, cross-arm 2, door leaf 4 are aluminium, plastic composite section bar with middle bank 7, and its exposed parts is band cavity aluminium alloy extrusions, and two aluminium alloy extrusions are installed with the PVC plastics and make many vacuum plastics section bar as disconnected cold bridge.The cooperation of two kinds of section bars is a dovetail type, and compound with the roll extrusion compounding machine is one.The straight non-loosening of section bar after compound.Doorframe 1 all adopts 45 to dock with door leaf 4, puts into the tension of inserted block 16 self threading pins in the angle, and cross-arm 2 is put into inserted block 16 respectively with middle bank 7 two ends and is plugged on doorframe 1 and the tension of door leaf 4 self threading pins.It is radial type that door leaf 4 cooperates with doorframe 1.Lap-joint has groove, and sealing joint strip 13 is housed in the groove.Door leaf 4 usefulness hinges 8 are fixed on the doorframe, and another fan limit of door leaf is equipped with to open and door lock 6 is housed below handle 5, the handle, and a pushing-type or pull-type door closer 3 are adorned in the doorframe top.As make clamshell doors, and be connected on the left-hand door limit with stile in the vacation 9 between its L.H.flapped door fan and R.H.flapped door fan, ensure door leaf is sealed.

Hollow glass can select for use variety classes glass to make as required, is divided into cavity with molecule plug parting bead is housed between two glass, and the plastics parting bead connects periphery and is sealed to firm one with glass cement with glass.Hollow glass is installed in the scene to carry out, at first install bright glass, before glass is installed, on cross-arm, be placed with pad 12 earlier, putting hollow glass 15, the side's of buckling profile 11,, carry over downwards and install door leaf glass with tower bar 10 jam-packs, door leaf glass not only has and is lined with pad 12 up and down, and two sides are also tight with pad 12 pads, change active force, prevent that free door limit from sinking.Buckle well triangle profile 14 usefulness tower bar jam-packs then.Hollow glass installs the outside, back and cooperates the place, angle to play the glass cement sealing with fixing along the glass aluminium alloy.

It should be noted last that, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
