The hardware includes a first hardware and a second hardware. The first hardware has a connection portion to the sash and a through-threaded hole, and the second hardware has a plate and one surface of the plate. It has an externally threaded male screw rod and an elastic urging piece provided on the other side of the plate, and the second metal plate and the elastic urging piece remain inside the base frame. With the elastic restoring force of the elastic biasing piece, the plate is elastically contacted with the back surfaces of both lips of the base frame, and the male screw rod is protruded outward through the opening of the base frame so as to be retractable, and The male threaded rod is connected to the first metal fitting connected to the sash. The sash mounting structure is characterized in that the first hardware and the base frame are connected and integrated by being penetrated through the through hole and screwed into the female screw member. .

[0006] With the above structure, the sash can be mounted as follows. That is, the connecting portion of the first hardware is connected to the sash, and the second hardware is set on the base frame in advance. The plate is elastically contacted by the elastic restoring force of the elastic urging piece with the back surface of both lips of the base frame, and is held in a state of being positioned with respect to the base frame by its stretching action. Next, the sash is assembled along the base frame. In this assembling operation, if the male screw rod is left protruding outward, the male screw rod hinders the assembly of the sash.
Therefore, the male screw rod is retracted into the base frame against the restoring force of the elastic urging piece. As a result, the sash can be assembled without the male screw bar being hindered.
Thereafter, the screw hole of the first metal fitting connected to the sash is aligned with the position of the male screw bar, and the male screw bar is protruded outward by the elastic restoring force of the elastic urging piece to penetrate the screw hole. Then, a female screw member is screwed into the screw rod and tightened. As a result, the first hardware and the base frame are fastened and tightly integrated, and the sash is securely attached to the base frame. In this way, the sash can be easily and reasonably mounted in a screw-on fashion without using welding on site.
