Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an insulated window framed in a rectangular shape by a frame in which an indoor frame and an outdoor frame are connected via a heat insulating material.

Prior art The upper frame, lower frame, left and right vertical frames are framed in a rectangular shape,
2. Description of the Related Art A heat-insulating window frame is known in which an indoor frame made of aluminum and an outdoor frame made of aluminum are formed, and both frames are connected via a heat insulating material so as not to be in direct contact with each other.

On the other hand, a construction method is known in which a window frame is attached in advance to a concrete panel constituting the outer wall of a building, and the concrete panel is attached to the building frame.

In order to pre-install the above-mentioned insulating window frame on the concrete panel, as shown in Figure 1a,
Insulated window frame b is set in formwork a, concrete c is poured between insulated window frame b and formwork a, and the entire structure is vibrated to form an upper frame d, a lower frame e, and
Concrete is injected into the outer recesses of the left and right vertical frames f, f, and after the concrete hardens, the formwork a is removed to form a concrete panel g with a heat insulating window frame b fixed inside, as shown in Fig. 1b. is being produced.

For this reason, a large force acts on each frame d, e, f, f, and each frame d, e, f, f may be bent inward as shown by the imaginary line. The frames d, e, f, and f need to be strong enough to withstand the above-mentioned large force and not bend inward.

Therefore, the interior and exterior of the indoor frame and the outdoor frame are connected by intervening inner and outer insulation materials, and a hollow is formed between the connection part of the indoor frame and the outdoor frame, and each Strengthens the frame.

On the other hand, in order to strengthen the attachment strength of the insulating window frame to the concrete panel, it is sufficient to form a recess with a large opening width on the outside of each frame so that a large amount of concrete can be injected and filled into the recess.

However, since the heat capacity of concrete is significantly larger than that of aluminum, if concrete is poured into the indoor frame, external heat will be transferred to the indoor frame through the concrete, reducing the insulation properties. It is not possible to form a recess into which concrete is poured.

For this reason, it is necessary to form a recess with a large opening width in the outdoor frame, and the outside of the outdoor frame protrudes largely to the outside of the indoor frame, so that the external insulation material is positioned closer to the indoor side than the inner insulation material. Become.

In particular, when the outdoor side of the insulated window frame and the outdoor side of the shoji are placed in the same position in the finding direction, the position of the outdoor side of the outdoor frame is regulated, and the outside of the outdoor frame does not protrude significantly toward the indoor side. Therefore, the outer insulation material is located closer to the room than the inner insulation material.

Because of this, when the upper and lower frames are butted against the vertical frame and connected with screws, the indoor side parts of the outdoor frames of the upper and lower frames will come into contact with a part of the indoor side frame of the vertical frame.
Since the outside air temperature is transmitted to the indoor side frame of the vertical frame from the outdoor side frame of the upper and lower frames, there is a problem that the insulation property is poor and dew condensation occurs on the indoor side frame.

Purpose of the invention The purpose is to increase the strength of the frame, form a recess with a large opening width, and provide excellent heat insulation.
