Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing an insulating profile made of an aluminum alloy or other metal that exhibits a dew condensation prevention function and is suitable for window frames and mullions.

Conventionally, this type of shape material was a circular material formed separately.
A rod-shaped connection +4 having heat insulating properties such as synthetic resin is inserted between the connection parts to create a gap.

In addition, the shape is initially formed, ): l) iM fixed shape, for example, the cross section is formed into a mouth shape, and the hollow part of the waist (2) is injected with synthetic resin liquid,
At the same time as it hardens, the entire length of the meat is tied to a thin strip from the opposite wall of the sword and cut away, forming a blocking part in the shape to prevent heat conduction.) This method is well known. In the former case, the connecting phase is inserted, but the difference (F
In the latter case, the synthetic resin liquid shrinks when it hardens, so there is no problem if the shape is thick, but if it is thin, the volume will increase. The changes caused the shape to deform.

This invention focuses on the following point-1- and solves the above-mentioned drawbacks using the German+'+)j method.Examples of the invention will be described with reference to the drawings.

The insulation profile is a divided profile (1) with the same shape on the left and right sides.
(2), in this case, the shape of (1) or (2) is extruded and molded.
Cut it to a predetermined length and attach it to the thread on the left side. Separate split sections extruded into a vertical shape are joined together. )(4)
There are protrusions (5) on the middle part of the wall (3) (4) and on the two parts.
)(6), (7) and (8) are protruded from left to right and facing each other, and the opposing protrusions (506) in the middle part are made of paper tape or synthetic resin tape with adhesive. Flexible adhesive tape (9) with double protrusions (5) (6)
They were connected with a gap between them, and room temperature curing synthetic resin liquid was injected and assimilated into the groove (10) formed by the adhesive tape (9) and both walls (3) and (4). Insulation/iig (1
This is a method of integrally joining the sections (+) and (2), which are divided into two parts iq by the insulation IVI (,1] ), with 1) interposed therebetween.

This invention is based on the following method, which uses the -month split key (
]) (2), connect the ridges (5) and (6) of the art shape (+) (2) with adhesive tape (9) with a gap between them, and then , H2) are sandwiched and fixed between predetermined jigs.

In this case, you can fix the drawing material (2) on the jig and then apply the adhesive tape (9). (6) Predetermined gap J,') between
! You can also connect them with a 1'l wide gap. After fixing it to the jig, inject room temperature curing synthetic resin liquid into the groove (10),
The hardened heat insulating layer (11) shrinks, but since the upper part of the groove (10) is open and the bottom is covered with flexible adhesive tape (9), only the open part and the bottom are deformed. No deforming force is applied to the J wall.

As mentioned above, the heat insulating shape according to the present invention does not distort the finished dimensions during molding, and even if it is a thin divided shape, the shape will deform due to the volume change when the heat insulating layer hardens. There is no risk of damage to the material, and it can be used as a moderately good heat insulating material.

In addition, since the forming method is easy and accurate, it can be formed into a composite shape made by joining multiple divided shapes, making it suitable for window frames in extremely cold regions. It has a great insulation effect against temperature differences between indoors and outdoors, and reliably prevents condensation.
