This relates to a window frame mounting structure characterized by being formed by screwing 18.

The first object of the present invention is to provide a window frame mounting structure that can be adjusted by sliding the L-shaped bracket or slide bracket even if the mounting position of the anchor board changes, and that allows the window frame to be easily mounted. be.

A second object of the present invention is to provide a window frame mounting structure in which the mounting structure is simplified by using a mounting screw body having an internal threaded portion and an external threaded portion.

A third object of the present invention is to provide a window frame mounting structure that allows easy adjustment work.

A fourth object of the present invention is to provide a window frame mounting structure in which the locking projections and depressions are engaged with the locking projections and depressions, so that the window frame can be reliably mounted.

The present invention will be explained in detail below with reference to Examples.

In the figure, reference numeral 1 denotes a new window frame to be installed, and its back is roughly shaped and has two walls 2 and 3 facing each other at right angles.

Opposing L-shaped ribs are provided on both sides of the inner surface of the front wall 2 over the entire length of the window frame 1 in the longitudinal direction, and these L-shaped ribs and the front wall 2 A groove is formed with the inner surface, and this groove serves as the engaging portion 4 facing each other.

Further, a rear protrusion 19 is provided at the rear end of the side wall 3 over the entire length of the window frame 1 in the longitudinal direction, and a protrusion that bends inward is provided at the tip of the rear protrusion 19. , this projecting piece is used as the engaging portion 4 of the side wall portion 3.

On both sides of the outer surface of the rear protruding piece 19, L-shaped body retaining pieces 20 are provided so as to protrude from each other and face each other over the entire length of the window frame 1 in the longitudinal direction.

In the figure, reference numeral 5 denotes an L-shaped metal fitting, in which a tip locking piece 21 bent in an L shape is provided at the tip of the front piece 6, and a base locking piece 22 is provided with a part of the base of the front piece 6 bent in an L shape. A part of the rear end of the side piece 6 is bent into an L shape to provide a two-pronged locking part 23.

The mounting threaded body A is formed by providing an internal threaded part 12 and an external threaded part 13 on the inner and outer surfaces of a cylindrical body, and a protruding base part 14 is provided by cutting and raising the center part of the L-shaped metal fitting 5. The mounting screw body A is mounted parallel to the side piece 7 by screwing the external threaded portion 13 of the mounting screw body A into the protruding base portion 14.

One piece of the L-shaped anchor board 9 is provided with a mounting hole 24, and the other part of the anchor board 9 has a long hole 10 and a locking unevenness 11. has a falling-off prevention piece 25.

Reference numeral 15 denotes a sliding metal fitting, and the sliding metal fitting 15 is provided with a long hole 16 and a locking unevenness 1T.

At the tip of the slide fitting 15, a thin neck piece 27 that is narrower than the width of the slide hole 26 of the side piece 7 of the one-shaped fitting 5 protrudes. The locking piece 28 is also wide and interposed between the slide fitting insertion grooves 38 and protrudes.

Therefore, when installing the window frame 1, the anchor board 9 is attached to the existing window frame 29 in the mounting opening 8 with screws 30 at arbitrary intervals.
It is fixed with a mounting bolt.

The end locking piece 21 of the front piece 6 of the one-sided metal fitting 5. The base locking pieces 22 are slidably engaged with the engaging portions 4 of the front wall 2 of the window frame 1, and the bifurcated locking portions 23 of the side pieces are engaged with the engaging portions 4 of the front wall 3 of the window frame 1. The L-shaped fitting 5 is slidably engaged with the engaging portion 4 to be slidable in the longitudinal direction of the window frame.

In this state, the window frame 1 is opposed to the mounting opening 8, and the front wall 2 tip of the window frame 1 is applied to the outer surface of the existing window frame 4 of the mounting opening 8 or the existing outer wall via the sealing material 31. and the rear end of the side wall 2 of the window frame 1 and the existing window frame 29 of the mounting opening 8.
A gap 32 is formed between the inner threaded part 12 and the elongated hole. 10, then insert the locking piece 28 into the slide fitting insertion groove 38 with the slide fitting 15 lying down, rotate the slide fitting 15 by 90 degrees and drop it in while raising it, thereby inserting the narrow neck piece 27. Insert into the slide fitting insertion groove 28,
In this state, slide the narrow neck piece 27 into the slide hole 26, and slide the slide metal fitting 1 between the fall prevention pieces 25 of the anchor board 9.
5 is inserted, and the locking unevenness 11 and the locked unevenness 17 are inserted.
The internal threaded portion 12 of the mounting screw body A is inserted through the elongated hole 16 of the slide fitting 15 and the elongated hole 10 of the anchor board 9.
Screw the male screw 18 onto the.

By the way, the anchor board 9 is attached to the existing window frame 27 of the mounting opening 8.
When installing the existing window frame 27, the existing window frame 27 is not flat but deformed and curved, so the protrusion length of the anchor board 9 is different. To compensate for the error in the protrusion length, slide the slide fitting 15 against the anchor board 9, This can be absorbed by changing the engagement position between the locking unevenness 11 and the locked unevenness 17.

Furthermore, due to on-site work errors, the mounting position of the anchor board 9 may shift in the front-back direction, but this shift in the front-back direction can be corrected by sliding the slide fitting 15 and screwing the mounting screw body A in the front-back direction. The slide fitting 15 can be reliably applied and fixed to the anchor substrate 9.

By the way, the gap 32 created for attaching the window frame 1 is covered by the cover material 33.
The side where 3 is installed is on the indoor side.

The cover material 33 has a substantially rectangular shape, and the tip of one piece is bifurcated. A U-shaped locking portion 35 is provided at the tip of the bifurcated outer piece 34, and a bifurcated inner piece 36 is provided. The locking claw piece 37
is the provision.

However, when installing the cover material 33, first
A U-shaped locking portion 3 is attached to one L-shaped body stopper 20 of the rear projecting piece 19.
6 is locked, rotate the cover material 34 to release the locking claw piece 3.
7 into the other L-shaped locking portion 20 of the rear protruding piece 19,
The cover material 34 is attached by bringing the tip of the other piece of the cover material 34 into contact with the rear surface of an existing window frame or the inner wall surface of a building wall via the sealing material 31.

As described above, even if the mounting position of the anchor board changes, the present invention can be adjusted by sliding the L-shaped metal fitting in the longitudinal direction of the window frame or sliding the sliding metal fitting in the front and back direction of the window frame, without using welding etc. The window frame can be easily attached to both, and since it uses a cylindrical mounting screw body with an internal threaded part and an external threaded part, it is easy to adjust the mounting screw body according to the position of the anchor board. The slide fitting can be fixed to the anchor board by moving the male threaded fitting and screwing it into the internal thread of the mounting screw body, and the structure is simpler than a structure in which multiple nuts are screwed onto a male threaded rod. In addition, the installation work can be easily performed, and the locking projections and recesses of the anchor board and the locking projections and recesses of the slide fitting engage with each other, so that the window frame can be reliably mounted.
