Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to a mounting bracket for installing a sash frame in an opening provided in a concrete wall and having a reinforcing frame made of angle material arranged around the periphery.

(Prior technology) Aerated concrete (ALC) that forms part of a building
A metal reinforcing frame is attached to the rectangular opening provided in the wooden wall on the indoor side of the opening.
This reinforcing frame is constituted by an angle member that abuts a peripheral edge inside the opening and a peripheral edge outside the opening adjacent to the peripheral edge.

Conventionally, a mounting bracket for supporting a sash frame within an opening using this reinforcing frame has been proposed (see Japanese Utility Model Publication No. 58-105984).

This mounting bracket includes a main body that is locked to a sash frame placed in an opening in a wall, a bearing part provided on the main body and extending in the thickness direction of the wall, and a shaft rotatably supported by the bearing part. , consisting of a mounting piece fixed to one end of the shaft and locked to the reinforcing frame inside the opening, and a mounting piece fixed to the other end of the shaft and facing the reinforcing frame outside the opening.

A screw member that can come into contact with the reinforcing frame is screwed into one of the mounting pieces located outside the opening, and the screw member is screwed so as to increase the distance between the one mounting piece and the reinforcing member. When the reinforcing frame is advanced toward the wall, the other mounting piece and the screw member press the reinforcing frame together. The sash frame is supported within the opening by holding the reinforcing frame between the other mounting piece of the mounting bracket and the screw member.

Incidentally, a sash frame installed in an opening in a wall is normally subjected to external forces such as wind pressure and seismic force that repeatedly act on the door attached to the sash frame.

When this external force is relatively small, no relative sliding movement occurs between the reinforcing frame and the other mounting piece and screw member that are in contact with the reinforcing frame. However, when the external force is relatively large, relative sliding movement between the reinforcing frame, the other mounting piece, and the screw member may occur, and therefore relative movement between the reinforcing frame and the sash frame may occur. For this reason, the sash frame may be inclined with respect to the reinforcing frame, resulting in an incompletely supported state.

Further, since the conventional mounting bracket has a complicated structure with a large number of parts, it is difficult to reduce its weight and cost.

(Purpose of the invention) Therefore, the object of the invention is to provide a mounting bracket that is applied to support a sash frame within an opening by a reinforcing frame attached to the edge of the opening in a wall,
The structure is as simple as possible, and the ability to prevent relative movement between the reinforcing frame and the sash frame caused by external forces such as earthquake force and wind pressure acting on the door placed in the sash frame can be further increased. The purpose is to provide mounting hardware.

(Structure of the invention) The present invention is a mounting bracket for installing a sash frame in an opening provided in a concrete wall with a reinforcing frame made of angle material arranged around the periphery. a first plate member having a base and a hook-shaped side; a second plate member having one side with a hole and the other side with a hole; and a hole in the first plate member. and a bolt having one end extending through a hole on one side of the second plate member and a hook-shaped other end, the bolt being screwed onto the one end of the bolt, and having one end extending through a hole on one side of the second plate member. a nut that can abut on the first plate member, the hole in the base of the first plate member is located outside the opening, and the side portion thereof is locked to the reinforcing frame inside the opening, and the second plate member The other side part is fixed to the sash frame via a screw passed through a hole in the other side part, the other end of the bolt is locked to the reinforcing frame, and the nut is tightened.

(Operations and effects of the invention) According to the mounting bracket according to the invention, the hole in the base of the first plate member whose side part is locked to one side of the reinforcing frame;
and passing one end of the bolt through a hole in one side of a second plate member having the other side fixed to a sash frame disposed in the opening in the wall, and inserting the other end of the bolt into the reinforcing frame. After the other side is locked, the sash frame can be supported by the reinforcing frame by engaging a nut with one end of the bolt and tightening it.

By tightening the nuts, the sash frame is supported by the reinforcing frame through both the bolt and the nut and the first plate member secured to one side and the other side of the reinforcing frame. Therefore, compared to the conventional mounting bracket that is supported on the reinforcing frame only by a member that is locked to one side of the reinforcing frame, the resistance against external forces that cause relative movement of the reinforcing frame and the sash frame is greater. can do.

Furthermore, the mounting bracket according to the present invention has few constituent members and has a simple structure. This not only makes it possible to obtain a reliable supporting capacity of the sash frame, but also makes it possible to reduce the weight and cost of the mounting hardware.

(Embodiments) The features of the present invention will become clearer from the following description of the illustrated embodiments.

Referring to FIGS. 1 and 2, a mounting bracket 10 according to the present invention is installed on a wall 12 made of aerated concrete (ALC) forming a part of a building, in which a rectangular opening 14 is formed, and on a wall 12 of the building. Opening 1 on the inside
Metal reinforcing frame 1 arranged along the peripheral edge of 4
6 and a sash frame 18 made of a metallic material such as aluminum, placed within the opening 14.

The reinforcing frame 16 is made of an angle member with an L-shaped cross section, and one side 16a of the angle member is connected to the opening 14.
fixed in contact with the peripheral edge 12a inside the
The other side portion 16b is fixed in contact with the peripheral edge portion 12b outside the opening 14.

The sash frame 18 is provided with two upper and lower rails 18a for a door (not shown) to be placed later.

The mounting bracket 10 for the sash frame 18 is the first
plate member 20, second plate member 22, and bolt 2
4 and a nut 25.

Each of the plate members 20 and 22 may have a relatively long length in the direction in which the reinforcing frame 16 extends, but as in the illustrated example, pieces having the same length are relatively small. It can also be composed of Depending on the length dimension, the number of combinations of bolts 24 and nuts 25 to be used is appropriately set to one or more. It is desirable that the mounting fittings 10 having a plurality of pieces be arranged in two pieces on each side of the rectangular shape of the opening 14.

The first plate member 20 is arranged along one side 16a of the reinforcing frame in the thickness direction of the wall 12, and the length dimension in the thickness direction of the wall 12 is the same as that of the one side 16a of the reinforcing frame.
Width dimension (length dimension in the thickness direction of wall 12)
It consists of a larger base 26 and a side part 28 connected to the base and fixed to the tip of one side part 16a of the reinforcing frame within the opening 14. The side portion 28 is formed into a hook shape by bending. It is desirable that the side portion 28 is formed such that its tip portion cuts into the wall 12 through the opening 14. Thereby, the locking of the side portion 28 to the reinforcing frame 16 can be made stronger. A hole 30 through which the bolt 24 is inserted is provided in the base 26 of the first plate member 20 at a position outside the opening 14 and close to the reinforcing frame.
