Description

  The present invention relates to a resin sash that can be easily attached to a housing opening of a building or the like, and in particular, can be easily welded to the housing opening.

  An aluminum alloy sash has been used as a sash provided in the opening of a housing of a building such as a house. Recently, a sash made of a synthetic resin such as polyvinyl chloride is used for reasons of heat insulation and corrosion resistance. (Hereinafter referred to as “resin sash”) has become widespread.

To fix the sash to the building opening of the building, nails etc. are used when the housing side is wood, but when the housing side is a metal such as iron, it is easy to weld by arc welding. Generally done widely.
By the way, in the case of a resin sash, welding is impossible as it is, so a metal frame, for example, an iron frame member is attached to the resin frame as a reinforcement, and this frame member is arc welded to the iron member of the housing opening. It is attached with.

FIG. 10 is a view schematically showing a conventional resin sash to which the iron frame member is attached, FIG. 10A is a plan view of the resin sash, and FIG. 10B is a cross-sectional view of the resin sash.
As shown in FIG. 10A, the conventional resin sash 101 is integrally fixed to the frames 104 and 105 with a synthetic resin vertical frame 104 and horizontal frame 105, for example, containing a glass shoji 102, and with a screw (not shown), for example. And four iron frame members 106.

The iron frame member 106 has an L-shaped cross section as shown in FIG. 10B, and the iron frame member 106 is fixed to the side surface of the vertical frame 104 with screws 107.
The iron frame member 106 is similarly fixed to the side surface of the horizontal frame 105 with screws (not shown).

  When the resin sash 101 is attached to a building frame, the iron frame member 106 is generally welded to the iron material of the building frame opening by arc welding. When performing arc welding, a welding machine (not shown) that holds a welding rod connected by a cable (manual welding torch) and a welding machine ground cable is connected to the base metal side. When the window frame is welded to the housing, an earth cable is connected to the window frame side, that is, the iron frame material 106 side in this case. Welding.

  By the way, the iron frame members 106 of the conventional resin sash 101 are linear and are not connected to each other. Therefore, when each iron frame member 106 integrally attached to the upper, lower, left and right resin frames in the figure is welded to the iron member of the housing opening, each iron frame member 106 must be grounded. Therefore, there is a problem that the efficiency of welding work is poor. Not only that, but particularly when welding is performed in a place where space is limited, the work of connecting the ground cable for each iron frame member 106 may not be easy, and there is a problem that the welding work is difficult. This is causing further deterioration in work efficiency.

  The present invention has been made to solve the above-mentioned conventional problems, and its purpose is to weld a plurality of iron sashes of a resin sash to a housing opening by simply taking one ground. It is possible to improve the efficiency of the installation work.

  The invention of claim 1 is a resin sash formed by combining a vertical frame and a horizontal frame made of synthetic resin, each of the vertical frame and a conductive metal frame member attached to the outer periphery of the horizontal frame, Conductive means for electrically connecting the metal frame members is provided at a joint between the vertical frame and the horizontal frame.

  According to the present invention, when welding a plurality of steel sashes of a resin sash to a housing opening, welding can be performed by taking only one ground, so that it is easy even in places where the space for welding work is limited. The ground can be taken, and the efficiency of the work of attaching the resin sash to the housing can be improved.
