Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[Industrial application] Aluminum, which is the main part of the sash, is a material with high thermal conductivity, so even if the sash has a multi-layered glass opening, the heat transfer between indoors and outdoors hardly changes. Insulating sashes, in which a heat insulating material is interposed between members to prevent the heat transfer and prevent dew condensation accompanying the heat transfer, are becoming mainstream sashes.

[0002] The present invention relates to a method for producing such a frame of a heat insulating sash (window frame) or a constituent material for a shoji.

[0003]

2. Description of the Related Art A resin-injection type in which a groove provided between indoor and outdoor members of an extruded aluminum material is filled with a resin solution and cured, and a hard resin material having an I-shaped cross section is formed by shaving a bottom wall piece of the groove. There is a caulking type which is interposed between indoor and outdoor members made of extruded aluminum members and crushes and engages a locking piece having a claw-shaped cross section provided on the facing surface side of the member.

[0004]

The resin injection type in the conventional example is not only complicated in shaving work, but also requires waste material treatment, and the shaved surface lacks a protective film due to surface treatment. There is a disadvantage that corrosion is easily caused.

Also, the caulking type has a drawback that the aluminum member is caulked and fixed to the hard resin material, so that there is a tendency to play back due to processing accuracy.

The present invention has been made in view of these drawbacks of the prior art, and has been aimed at always obtaining a heat insulating sash component having a dimensional shape exactly as designed.

[0007]

Means for Solving the Problems A receiving member made of a heat-insulating synthetic resin is interposed between an indoor and an outdoor aluminum profile formed separately from each other, and a groove having the receiving material as a bottom wall is formed in the indoor and outdoor. The basic means is to form along the longitudinal direction of the aluminum profile and then fill and cure the groove with a resin solution to form a heat-insulating bridge material and connect and fix the indoor and outdoor aluminum profiles to each other. And

The receiving member is interposed between both aluminum members by means of receiving both ends on a support piece provided on the opposing surface of the aluminum member or engaging an engaging groove. In particular, the inner and outer aluminum profiles can be firmly connected and fixed by sliding the thick ends into the dovetail-shaped engagement grooves,
As means for firmly connecting and fixing, there is also a means for forming a groove having a groove portion, or a method for filling and curing a resin liquid material between a component of an engaging groove and a receiving material.

The width of the heat-insulating bridge material is made wider than that of the receiving material in the width perpendicular to the connection direction of the indoor and outdoor aluminum profiles, so that the receiving material is connected and fixed to both aluminum profiles. As a main member, resin liquid is used for the purpose of preventing rattling occurring in the gap between the aluminum profile and the receiving material, dimensional regulation, and water stop treatment. In this case, the receiving material is made of aluminum and has a groove-shaped engaging groove. By sliding, uniformity of strength quality can be achieved and stable strength can be obtained. Also, since the usage fee of resin solution is small, material cost is low, production speed is fast and overall speed is low. Can be done at cost.

In order to accelerate the curing, a thermosetting material or an ultraviolet curable material may be used as the liquid.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a sectional view of a product to which a method of manufacturing a heat insulating sash component according to the present invention is applied. FIG. 1 is a sectional view of a first embodiment, FIG. 3 is a sectional view of the third embodiment.

In the figure, A is a sash component for heat insulation, and component A is an indoor aluminum part 1 and an outdoor aluminum part 2 formed separately from each other. Bridge material 3
And the receiving member 4 are interposed and fixed to each other in the indoor and outdoor directions.

The indoor and outdoor aluminum profiles 1 and 2 are formed by an extrusion molding machine according to a conventional method. A thick end 4a along the longitudinal direction of the receiving member 4 is slidably fitted into the engaging grooves 5 and 5, and a groove 6 having the receiving member 4 as a bottom wall is formed in the longitudinal direction of the shaped members 1 and 2. After that, the groove 6 is filled with a resin solution and cured to form the pre-insulating bridge material 3, and the indoor and outdoor aluminum profiles 1 and 2 are adhered and fixed to obtain the constituent material A. It is.

In the first embodiment shown in FIG. 1, the width (found width) in the direction perpendicular to the connecting direction of the aluminum profiles 1 and 2 inside and outside the room
Is a main member for connecting and fixing the aluminum profiles 1 and 2 by making the heat insulating bridge material 3 wider than the receiving material 4. The receiving material 4 has neck portions at both ends along the longitudinal direction. A thick end 4a is provided adjacent to 4b, and the end 4a is slidably fitted in the dovetail-shaped engaging groove to connect the two profiles 1 and 2 to each other to form the groove 6. However, the L-shaped free end 7 ′ of the component 7 on the groove 6 side, which constitutes the engagement groove 5.
The receiving member 4 and both the shaped members 1 and 2 are assembled together so that a gap 8 is formed between the receiving member 4 and the receiving member 4 to form the groove 6.

The groove 6 is formed by projecting, at the time of molding, a piece 9 having a thicker front portion on the facing surfaces of the aluminum profiles 1 and 2 inside and outside at the time of molding, and placing the pieces 9 and 9 in the facing position. When a resin (polyurethane in this embodiment) liquid is injected into the groove 6, the liquid is supplied not only to the inside of the groove 6 but also to the gap 8 communicating with the groove 6. The inflow filling is performed, and the filled resin solution is cured to form the heat insulating bridge material 3, whereby the sash component A for heat insulation is formed.

By filling the gap 8 with a resin solution, there is no backlash between the receiving member 4 and the aluminum profiles 1 and 2 and the heat-insulating bridge member 3, and this is more firmly fixed.

Further, by forming the groove portion 6 into a dovetail shape,
It is possible to prevent the heat-insulating bridge material 3 from peeling off from the profiles 1 and 2 and rattling.

In the second and third embodiments, contrary to the first embodiment, the receiving material 4 for the resin solution (bridge material 3) is made wider than the bridge material 3 (the height is wide in the drawing). The receiving material 4 is used as a main member for connecting and fixing the aluminum profiles 1 and 2, and the heat-insulating bridge material is used for preventing rattling or water stopping. Engagement grooves 5, 5
The end 4a corresponding to the engagement groove 5 is formed in the same manner as in the first embodiment, and the receiving member 4 and the indoor and outdoor aluminum members 1, 2 are assembled together as in the first embodiment. Then, a groove 6 having the receiving material 4 as a bottom wall is formed, and a resin solution is injected and filled into the groove 6, which is cured to obtain a product A as the bridge material 3.

In the second and third embodiments, a profile member having a groove 6 as in the first embodiment and forming a groove may be used. By using a material having such a shape that the formed air layer 10 is formed, it is possible to provide a sash component material A having a more excellent heat insulating effect.

In each of the embodiments, the engaging groove 5 is preferably provided with a groove, but it is not always necessary to have the groove. There is also a means for receiving the receiving material. If the receiving means may be placed on the receiving piece, a groove may be provided on the receiving material side, and the receiving means may be slidably fitted on the receiving piece.

[0021]

According to the present invention, a uniform heat insulating sash component can be obtained without waste material.
