Abstract
The utility model discloses a barrier strip type heat insulation section bar combination, comprising a left section bar (1) and a right section bar (2), which are symmetrically disposed and on the opposed faces of which are disposed notches (3), between the left section bar and the right section bar are disposed heat insulation strips (4), two ends of which (4) respectively enter into the notches (3) of the two section bars. The barrier strip type heat insulation section bar combination can not only improve quality of doorframe, but also improve adhesive force and hardness of coating.
Description
Technical field
The utility model relates to a kind of bar penetrating type heat-insulation section bar combination.
Background technology
At present, along with being surging forward of real estate, the consumption of alumium alloy door and window increases sharply, because it is more and more higher to the requirement of energy-saving and emission-reduction, therefore the heat-insulating property to alumium alloy door and window has proposed very high requirement, therefore present alumium alloy door and window generally adopt heat insulated shape bar of aluminum alloy, heat insulated shape bar of aluminum alloy has two kinds of processing modes, a kind of is penetrating bar type, a kind of is glue injection type, the processing method of bar penetrating type heat-insulation section bar is that (powder sprayed after at first independently aluminium extruded sections passed through surfacing with two, electrophoresis sprays paint, transfer printing wood grain, heat-tinting etc.), pass through tooth punching then, wear bar, roll-in combines, the section bar that the surface is treated to powder spraying is through after the roll-in, occurs the phenomenon that powder splits easily wearing bar notch position people, influences the quality of doorframe.
Summary of the invention
The utility model provides a kind of bar penetrating type heat-insulation section bar combination, and it not only can improve the quality of doorframe, and the hardness of adhesive force of coatings and coating has been improved.
The technical solution adopted in the utility model: a kind of bar penetrating type heat-insulation section bar combination, it comprises left profile and right profile, left profile and right profile are symmetrical arranged, the opposite face of described left profile and right profile is provided with notch, be provided with heat insulating strip between left profile and right profile, the two ends of heat insulating strip penetrate respectively in the notch of two section bars.
Described notch top and bottom are set to step, and a side of step contacts with section bar, are round transition I between step bottom surface and the contacted section bar surface.Between described step bottom surface and the side round transition II.The side height of described step equal the to contact height on section bar surface with step.Described and the height contacted section bar of step surface is 1.5mm.
The utlity model has following beneficial effect: be provided with heat insulating strip between left profile of the present utility model and the right profile, the two ends of heat insulating strip penetrate respectively in the notch of two section bars, can improve the heat-insulating property of window frame like this.The step place of the top of the utility model notch and bottom is provided with round-corner transition, thereby avoids forming the powder accumulation in the corner of step, thereby controls the uniformity of coating layer thickness, has avoided the phenomenon of powder accumulation effectively, has alleviated the local thick partially phenomenon of coating.Prevent to produce local distortion, cause coating cracking.Of the present utility model when extruding aluminium ingot temperature be controlled at 500 ℃, the speed of extruding is controlled at 12 meters/minute, can improve the intensity of section bar like this.Solidification temperature 200-220 during the utility model electrostatic powder coating ℃, the time of curing is 14-15 minute, and adhesive force of coatings and coating hardness are significantly improved.
