Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to a metal fitting for attaching a lower frame that forms a part of the window frame to the frame when the window frame is installed in the opening of the frame.

(Prior art) When fittings such as aluminum sashes are attached to an opening in a frame of a structure such as a wall, it is possible to smoothly open and close a shoji installed in a window frame that forms a part of the fittings. Therefore, the window frame is placed horizontally in the opening and fixed.

For example, in order to install a window frame in an opening in a frame made of a reinforced concrete wall, the mounting bracket is used to attach the lower frame to the lower part of the opening. A metal fitting consisting of a connecting part extending toward the bottom of the is used.

Fixing the lower frame to the lower part of the opening using these mounting brackets involves placing the window frame with the mounting brackets attached at multiple locations on the lower frame within the opening, and maintaining it horizontally. This is done by welding the connection portion of each fitting to each anchor bar extending upward from the bottom of the opening.

The conventional mounting bracket functions as a connector between the lower frame and the lower part of the opening, and also as a spacer between them after the connection. However, it does not have a level adjustment function for the lower frame, which is necessary for positioning the window frame when installing the window frame. For this reason, installing window frames requires tools and equipment for this level of adjustment, as well as manpower to handle them, and skill may be required to handle these tools and equipment.

(Purpose of the invention) Therefore, in view of the above-mentioned circumstances, an object of the present invention is to provide a mounting bracket that can adjust the level of a window frame when it is installed in an opening of the window frame.

(Structure of the invention) The present invention is a metal fitting for attaching the lower frame of a window frame installed in an opening of a building frame to the lower part of the opening opposite to the lower frame, and the metal fitting is provided with a first screw that opens laterally. an anchor member provided with a hole and a second screw hole and an inclined surface; a wedge member located below the anchor member and in contact with the inclined surface and forming a sliding pair with the anchor member; a wedge member provided with a screw hole that aligns with a second screw hole of the anchor member; It includes a screw member for changing the relative position of the wedge member, and a connecting member having a long hole extending in the vertical direction, the anchor member being fixed to the lower frame, and the wedge member hitting the lower part of the opening. The connecting member is fixed to the lower part of the opening and is fixed to the anchor member via a screw member that is passed through the elongated hole and the first screw hole of the anchor member.

(Operations and effects of the invention) According to the invention, the level of the lower frame to which the anchor member is fixed is such that the screw member that screws the wedge member into the second screw hole of the anchor member through the screw hole thereof is set at the level of the lower frame to which the anchor member is fixed. By turning the wedge member to change the relative position of the wedge member with respect to the anchor member, adjustment can be made easily and in a short time. The adjusted level can be maintained by tightening the connecting member and the anchor member with a screw member passing through the elongated hole and the first screw hole. The long hole extending in the vertical direction of the connecting member allows the threaded member to be inserted into the first threaded hole of the anchor member, which moves in the vertical direction as the relative position of the wedge member changes. forgive.

It has c. These pair of flange portions 26c
are inclined such that the distance from the upper plate portion 26a gradually increases from the indoor side to the outdoor side, and the lower surface of each of the anchor members defines the inclined surface of the anchor member 20.

Each flange 28 extends toward each side (not shown) of the opening perpendicularly to each side plate portion 26b of the main body. Each flange 28 is provided with a screw hole (first screw hole) 28a that opens laterally. Instead of the illustrated example in which each flange 28 is formed by welding plate pieces, each flange 28 can also be formed by making necessary cuts and bending the metal plate together with the main body 26.

The anchor member 20 has a hanging piece 3 formed by partially cutting two strips in the upper plate portion 26a of the main body from the indoor end toward the outdoor side and bending it downward.
