Description

[Detailed Description of the Invention] This invention relates to an improvement in the heat insulating connection structure of a double sash window frame in which a heat insulating material is interposed between the outer frame and the inner frame of the window frame.

BACKGROUND ART Conventionally, a window frame is already known in which a heat insulating material is interposed between an outer frame attached to the outside of a building and an inner frame attached to the inside of the building to block heat conduction between the two.

This invention is a further improvement of the heat insulating connection structure of window frames, in which a heat insulating material is attached to the frame material extending along the periphery of the outer frame toward the opening side, and this heat insulating material is attached to the inner frame at the crimping part. In addition to increasing the airtightness by crimping, the outer frame and the inner frame are connected and integrated by using the frame portion and the overhanging portion, and placing the heat insulating material close between them, and at appropriate intervals in the longitudinal direction of the frame material. This is intended to provide a heat-insulating connection structure for window frames in double sashes that are firmly and integrally connected to each other by using hard and heat-insulating mounting blocks provided with the mounting blocks. In addition to making it possible to integrate the windows in advance and transport and install them on site, it also makes it easier to handle the double window frames at that time, and in addition, the above-mentioned airtight insulation structure can be reliably maintained. This is how it was done.

This invention will be described in detail below with reference to an illustrated embodiment.

In the figure, reference numeral 1 denotes an opening of a building, and the peripheral material forms a window frame attachment part, and an outer frame 3 is attached to the outdoor side of the opening, and an inner frame 2 is attached to the indoor side of the opening.

The frame portion 5 of the outer frame 3 extends along the inside of the opening 1 from the building attachment portion 4 on the vertical wall surface on the outdoor side of the opening peripheral material, and the mutually opposing surfaces of the frame portion 5 are insulated. A fitting space 7 of the material 6 is formed over the entire circumference.

As shown in FIG. 3, the fitting space 7 is divided by rising portions 8 and 9 that are spaced apart from each other in the width direction of the frame. A protrusion 10 is provided in a protruding manner opposite to the portion 8.

The groove 6a of the heat insulating material 6 inserted into the fitting space 7 is press-fitted into the protrusion 10, and the heat insulating material 6 is inserted into the fitting space 7.
is fixed.

The heat insulators 6 are made of, for example, a closed-cell foam material and are formed in an endless shape, and are attached to the inner side of the frame portion 5 of the outer frame 3 so as to overlap around the entire circumference.

The one-way side frame 2 has a guide section 12 for the shoji door 11, and a frame-shaped projecting section 13 extending toward the outside of the room.

A crimping part 13a is formed at the tip of the overhanging part 13, and the heat insulating material 6 is connected to the frame part 5 of the outer frame 3 and the crimping part 13a.
In addition, between the overhanging part 13 and the frame part 5 of the outer frame 3, the heat insulating material 6 is located close to the rear side and is spaced appropriately in the longitudinal direction of the frame material. A block 14 is used for attachment.

In the above installation, the block 14 is used to position the inner and outer frames 2 and 3, maintain an appropriate distance between them, and firmly connect and integrate the inner and outer frames 2 and 3. It is made of hard synthetic resin or the like, and as shown in FIG. 4, has a through hole 16 for inserting a fastener 15 such as a wood screw, and screw holes 17 on both sides thereof.

A screw 18 is inserted into each screw hole 17 from the side of the outer frame 3 and whose tip does not reach the inner frame 2, fixing the outer frame 3 and the mounting block 14. A screw 18 is inserted from the side and the tip does not reach the outer frame 3, and the inner frame 2 and the block 14 are fixed to each other. It is connected and integrated.

A fixing tool 15 is inserted into the through hole 16 from the inner frame 2 side.
is inserted.

The distal end side of the fixing tool 15 is screwed into the opening 1 through a sufficiently large diameter through hole 19 bored in the frame portion 5 of the outer frame 3.
Inner and outer frames 2 and 3, which are connected and integrated, are attached to the opening 1.

According to the window frame structure according to this invention, when installing the window frame in the opening 1 of the building, the inner and outer frames 2 and 3 are connected and integrated by the block 14 in advance, so that the inner and outer frames 2 and 3 are connected to the opening 1. Installation in step 3 can be completed in one go.

Also, the installation is done using the block 14 on the overhanging part 1 of the inner frame.
3 and the frame portion of the outer frame, and a frame connecting portion that is integrally connected to the frame portion of the outer frame, and a crimping portion 13a at the tip of the overhang portion 13, which is fixed to the frame portion 5 in the vicinity of the block.
The inner and outer frames 2 and 3 are strongly integrated with each other due to the interaction with the sandwiched part of the insulation material 6 that is crimped with Frame transportation/
It is easy to handle the frame during installation, the frame does not twist, and it can be fixed to the opening while maintaining the correct frame form, making it easy to accurately install double window frames. .

In addition, since the heat insulating material 6 is provided endlessly around the entire circumference of the outer frame 3, and this heat insulating material 6 is sandwiched between the crimp portions 13a of the inner frame 2, a high degree of airtightness is achieved between the inner and outer frames 2 and 3. Moreover, heat conduction between the inner and outer frames 2 and 3 can be sufficiently blocked.

Further, a mounting block 14 is provided close to the heat insulating material 6, and the block 14 connects and fixes the inner and outer frames 2.3 to each other, and at the same time, the mounting block 14 is inserted into the block 14 and the outer frame 3 from the inner frame 2 side. Since the inner and outer frames 2 and 3 are fixed to the building using the fasteners 15, the inner and outer frames 2 and 3 can be easily and precisely attached to the building, and the installation is free from vibrations caused by opening and closing the rear window. etc. are inner frame 2
Even if the inner and outer frames 2 and 3 are
There is no gap between the heat insulating material 6 and the inner and outer frames 2 and 3, and a good heat insulating effect can be maintained over a long period of time.
