Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulating sash, and more particularly to a heat insulating sash capable of preventing water leakage from a joint end of a heat insulating bridge material at a joint between a lower frame and a vertical frame.

[0002]

2. Description of the Related Art A heat insulating sash of this type is disclosed in Japanese Patent Laid-Open No.
Those disclosed in Japanese Patent Publication No. 146736 and the like are known. This heat insulating sash has a metal shape in which an upper frame (not shown) constituting the sash frame 1, a lower frame 1b and left and right vertical frames 1c are divided into an outdoor side and an indoor side, as schematically shown in FIG. The materials 1x and 1y are connected to each other via a heat insulating bridge material 3 made of resin.

Further, in the above heat insulating sash, if the exposed surface of the heat insulating bridge member 3 is recessed from the surface of the shape members 1x and 1y, a gap is created at the joint 5 between the lower frame 1b and the vertical frame 1c. Since rainwater or the like may leak through the gap to the back side of the sash frame 1 and wet the body of the building, the exposed surface of the heat insulating bridge member 3 is formed into the shape members 1x, 1 for the purpose of preventing this.
It is formed flush with the surface of y.

[0004]

However, in the heat insulating sash, the heat insulating bridge material 3 contracts in the longitudinal direction due to secular change or the like, and the heat insulating bridge material 3 in the joint portion 5 between the lower frame 1b and the vertical frame 1c. It is conceivable that a gap s is generated at the joining end 3a. Also, in an actual construction site, the wood of the frame of the building to which the sash frame is attached has a slight warp or bend, and if this becomes large over time, unexpected force will act on the sash frame, causing internal stress. As a result, a gap may be generated at the joint end of the heat insulating bridge material. When a gap is created at the joint end of the heat insulating bridge material like this, rainwater etc. may leak through the gap to the back side of the sash frame and wet the building's skeleton, damaging the skeleton and damaging the reliability of the heat insulating sash. is there.

Therefore, an object of the present invention is to prevent leakage of water from the gap even if a gap is formed at the joint end of the heat insulating bridge material at the joint between the lower frame and the vertical frame due to aging or the like. It is to provide a highly reliable heat insulating sash capable of

[0006]

In order to achieve the above object, in the heat insulating sash according to claim 1, an upper frame, a lower frame and left and right vertical frames constituting a sash frame are divided into an outdoor side and an indoor side. A heat-insulating sash made by connecting metal shape members through a heat-insulating bridge material made of resin, and a water leakage prevention member that watertightly covers the joint end of the heat-insulating bridge material at the joint between the lower frame and the vertical frame. It is characterized by being provided.

According to another aspect of the heat insulating sash of the present invention, there is provided a fixed body to which the water leakage prevention member is fixed in the vicinity of the joint between the lower frame and the vertical frame, and a fixed body provided on the fixed body for joining the heat insulating bridge member. It is characterized by comprising an elastic sealing material that covers the end in a watertight manner.

According to the heat insulating sash of claim 1, the upper frame, the lower frame and the left and right vertical frames constituting the sash frame are divided into the outdoor side and the indoor side. Since a water leakage prevention member that covers the joint end of the heat insulating bridge material in a watertight manner is provided at the joint between the lower frame and the vertical frame, the lower frame and the vertical frame are joined even if they change over time. Even if a gap is generated at the joint end of the heat insulating bridge material in the portion, water leakage from the gap can be prevented by the water leakage prevention member, and reliability is improved.

According to another aspect of the heat insulating sash of the present invention, the water leakage preventing member is elastically covered in a watertight manner on the joint end of the heat insulating bridge member to the fixed body fixed near the joint between the lower frame and the vertical frame. Since the sealing material is provided, a reliable water leakage prevention effect can be obtained with a simple structure.
