Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anchor metal member for fixing a window frame used for attaching the window frame to an opening of a frame, and particularly when engaging with a locking piece of the window frame. In addition to improving installation workability, when the engagement is completed, the window frame is held so as not to shift due to crimping of the engagement pieces, and the engagement is prevented from being disengaged due to excessive turning or accidental external force. The present invention relates to an anchor metal piece for fixing a window frame, which is applicable to window frames having different cross-sectional shapes under the window.

[0002]

2. Description of the Related Art Conventionally, when a window frame is fixed to a building opening of a building or the like, as shown in FIGS.
Bringing the window frame fixing anchor metal piece (hereinafter, simply referred to as the anchor metal piece) 1 to the back surface of the window frame 2 and rotating it at an angle around an axis orthogonal to the main body 1B surface as shown in FIG. Engagement receiving portions 1A, 1 formed on the
A is locking pieces 2a, 2 protruding inward in the width direction of the window frame 2
Then, the anchor foot 1C of the anchor metal fitting 1 is fixed by welding to the reinforcing bar 4 which is embedded in the concrete skeleton 3 in advance, and then the window frame 2 and the anchor metal fitting 1 and the concrete skeleton 3 are fixed. The space is filled with mortar 5, and the periphery of the window frame 2 is finished into a predetermined shape.

As the anchor metal piece 1 in this case, as shown in FIG. 11, there is used a main body 1B having engagement receiving portions 1A, 1A formed at both ends thereof, which are open to the outside.

[0004]

However, in the engagement receiving portion 1A of the anchor metal fitting 1, the engagement receiving piece on one side and the engagement receiving piece on the other side are formed substantially parallel to each other, and the fitting inlet width Is constant in all three directions (tip side and both sides). Therefore, if the width of the fitting inlet is too narrow, it becomes difficult to fit the window frame into the locking piece, and if the thickness is approximately the same as the thickness of the window frame locking piece, the crimping force of both engagement receiving pieces Since the anchor is weak, the anchor hardware can easily shift,
There was a problem such as disengagement.

Further, in the case of an anchor metal piece to be engaged with the window frame 2A having the shape shown in FIG. 4, the vertical walls 2c and 2d adjacent to the locking pieces 2a and 2b are used.
The size of the anchor metal fitting must be adjusted to the distance W ₀ between c and 2d. However, when the anchor metal fitting used in this case is engaged with the window frame 2B having the shape shown in FIG. Since the metal fitting 1 is easily displaced in the indoor / outdoor direction, the window frame cannot be firmly held. In order to deal with such a problem, it is necessary to separately prepare anchor metal fittings with different dimensions for each window frame type, which complicates inventory management, and supports anchor metal fittings and window frame types on site. It is very complicated in terms of construction, such as having to install while doing so.

[0006] To solve this problem,
No. 85 proposes an anchor device in which a small suspension piece and a large suspension piece are provided above and below a suspension piece joined to an anchor rebar. According to this anchor, since two types of suspension dimensions can be adopted, one type of anchor can be used in common. However, in the case of this anchor, if one of the suspension pieces is attached to the window frame, the other unnecessary suspension piece will largely project to the side, and the protruding suspension piece will obstruct the mounting location. Limited. In particular, when the small suspension piece is locked to the narrow window frame, the large suspension piece may protrude beyond the width of the window frame. Moreover, the bending process is performed from a large original plate, and the process becomes complicated, resulting in high cost.

On the other hand, in the case of the conventional anchor hardware 1,
The main body 1B has engagement receiving portions 1A and 1A at both ends,
Approximately 9 anchors 1 around the axis perpendicular to the body 1B surface
Although it is attached by rotating it by 0 degrees, there is a problem that it may come off from the window frame 2 when it is rotated too much and the window frame receives an unexpected external force.

Therefore, the main object of the present invention is, firstly, to improve the mounting workability when engaging with the locking piece of the window frame, and when the engagement is completed, the window is formed by crimping the engaging pieces. Being able to hold the frame so that it does not shift,
Secondly, it prevents the engagement from being disengaged due to excessive turning or accidental external force, and is commonly used even if the window frames having different cross-sectional shapes have the same distance between the window frame locking piece tips. The purpose of the present invention is to provide a window frame fixing anchor metal fitting that enables the convenience of inventory management and construction.

[0009]

In order to solve the above-mentioned problems, the first aspect of the present invention relates to an angle formed around an axis orthogonal to the anchor body surface with respect to the locking pieces formed on both sides of the window frame rear surface. An anchor metal member for fixing a window frame that is engaged by rotating to support the window frame, and engages by engaging the locking pieces on the back surface of the window frame on both sides of the substantially plate-shaped anchor body. In each of these engagement receiving portions, the engagement opening width of one side that is first fitted into the engagement piece of the window frame when being rotated and attached is set to the engagement piece. The thickness of the other side is smaller than the thickness of the locking piece while the other side is made slightly thicker than the thickness of the locking piece. In this case, the engagement receiving portion is composed of an inner engagement piece in the substantially center and outer engagement pieces on both sides thereof, and the surface of the inner engagement piece is inclined to form the above-mentioned one. It is possible to satisfy the condition that the width of the side fitting hole is slightly larger than the thickness of the locking piece while the other side is smaller than the thickness of the locking piece.

Therefore, in the case of the first aspect of the invention, when the anchor metal piece is rotated to be engaged with the window frame locking piece, the fitting opening width of one side which is first fitted is equal to that of the locking piece. Since it is formed slightly larger than the thickness, the window frame locking piece can be easily fitted into the engagement receiving portion of the anchor metal piece. After that, when the anchor metal piece continues to rotate and the attachment of the anchor metal piece is completed, it is in a state of being sufficiently crimped by the engagement pieces on both sides that sandwich the window frame locking piece. It will not be easily displaced.

Next, according to the second aspect of the present invention, the locking pieces formed on both sides of the rear surface of the window frame are engaged by being rotated at an angle around an axis orthogonal to the anchor body surface,
An anchor metal fixture for fixing a window frame, comprising: engagement receiving portions for engaging the locking pieces on the back surface of the window frame by sandwiching the locking pieces on both sides of the substantially plate-like anchor body. An engaging step portion that abuts against the tip end surface of the window frame locking piece is formed at a position that does not hinder the rotational engagement of the anchor metal piece.

Therefore, in the case of the second aspect of the invention, when the anchor metal piece is rotated to be engaged with the window frame locking piece, even if the anchor metal piece is urged to rotate, the engagement stepped portion is the window frame engaging member. Since it collides with the front end surface of the stop piece, it will not come off due to excessive rotation. Further, even after the mounting is completed in a predetermined state, the engaging stepped portion is in contact with the tip end surface of the window frame locking piece, so that the anchor metal fitting is not displaced in the indoor / outdoor direction. The frame can be held firmly.

Further, the fixing anchor metal piece for a window frame which is a combination of the first invention and the second invention is more suitable.

[0014]

Embodiments of the present invention will be described below in detail with reference to the drawings. As shown in FIG. 1, in fixing the window frame 2 to the skeleton opening 3 of a building or the like,
The anchor metal fitting 10 according to the present invention is brought to the back side of the window frame 2 and is rotated at about 90 degrees around an axis orthogonal to the surface of the main body 11 as shown in FIG. The engagement receiving portions A and B are engaged with the locking pieces 2a and 2b projecting inward in the width direction of the window frame 2, and then the reinforcing bars 4 are embedded in the concrete frame 7 in advance. The anchor foot 12 of the anchor metal fitting 10 is fixed by welding while interposing 6 and then the space between the window frame 2 and the anchor metal fitting 10 and the concrete skeleton opening 3 is filled with mortar 5, and the periphery of the window frame 2 is surrounded. This is done by finishing into a predetermined shape. The construction procedure is exactly the same as the conventional case.

As shown in FIG. 2, the anchor metal piece 10 is formed by punching out in a substantially U-shape at a central portion of a main body 11 made of a substantially rectangular plate-like member and standing it up 90 degrees. And the engagement receiving portions A and B that engage with the locking pieces 2a and 2b formed on the window frame are formed on both opposing short sides.

The engagement receiving portion A forms punching lines C ₁ and C ₂ which are orthogonal to the short side of the main body 11 and are parallel to each other, and a portion between the punching lines C ₁ and C ₂ is obliquely downward. The inner engaging piece 13a formed by bending and re-bending from the intermediate position in a direction substantially along the surface of the main body 11 and left unprocessed on both sides across the inner engaging piece 13a The outer engagement pieces 15a and 16a are formed, and the inner engagement pieces 13a and the outer engagement pieces 15a and 16a are formed.
The locking pieces 2a and 2b on the rear surface of the window frame are sandwiched and engaged in the gap portion formed by a. In addition, the other side of the main body 11 is also point-symmetrically similarly the inner engagement piece 13b,
An engagement receiving portion B is formed by the outer engagement pieces 15b and 16b.

Particularly in the case of the present invention, the engagement receiving portions A,
In B, the width S ₁ of the one-sided fitting opening M ₁ that is first fitted into the window frame locking pieces 2a and 2b when the main body 11 is rotated and attached is set to the thickness of the window frame locking piece 2a. While being slightly larger than t, the width S ₂ of the mating inlet M ₂ on the other side is smaller than the thickness t of the locking piece 2a. That is, as shown in FIG. 3, since the outer engagement pieces 15a and 16a are unmachined and have the same surface as the main body 11, the inner engagement pieces 13a are formed by inclining the surfaces during bending. As a result, if the widths S ₁ and S ₂ of the fitting openings M ₁ and M ₂ formed between the outer engagement pieces 15a and 16a are different from each other under the conditions of S ₁ > t and S ₂ <t. It is tight.

Therefore, the anchor metal 1 is attached to the main body 1
The locking piece 2 of the window frame 2 is rotated by rotating around an axis line orthogonal to one surface.
Since the fitting port M ₁ is larger than the thickness t of the window frame locking piece 2a when engaging with the locking pieces 2a and 2b, the locking piece 2 can be easily
a can be fitted between the inner engagement piece 13a (13b) and the outer engagement pieces 15a, 16a (15b, 16b) of the anchor metal fitting 1, and then the rotation is continued to the longitudinal axis of the window frame 2. On the other hand, in a state where the longitudinal axes of the main body 11 are orthogonal to each other, that is, when the attachment is completed, the window frame locking piece 2a (2
b) is the inner engagement piece 13a (13b) and the outer engagement piece 15
a, 16a (15b, 16b) and the window frame locking piece 2
Since a is clamped in a state of being sufficiently crimped, the window frame 2 will not be easily displaced thereafter.

Incidentally, the structures of the engagement receiving portions A and B can be modified in various ways within the scope of the present invention. For example, it is possible to make the inner engagement piece 13a a flat surface while bending the outer engagement piece 16a side to increase the width S ₁ of the fitting inlet with the inner engagement piece 13a. It is also possible to substantially narrow the fitting inlet width S ₂ by forming the inner engagement piece 13a as a flat surface and forming a protrusion on the outer engagement piece 15a side. Further, in this embodiment, the anchor metal piece is formed by processing from a single plate for the sake of simplicity of manufacture. However, the member corresponding to the anchor foot piece 12 is separately fixed by welding or the like, and the engagement receiving portion A is also used. , B, the central engaging pieces 13a, 13b may be fixed by welding or the like.

On the other hand, according to the present invention, the window frame locking pieces 2a, 2b are arranged at positions that do not hinder the rotational engagement of the anchor metal piece, in the illustrated example, with respect to the outer engaging pieces 15a, 15b.
Engaging step portions 14a and 14b are formed so as to abut against the tip surface of the. The distance L between the engagement step portions 14a and 14b is the W dimension in FIGS. 4 and 6, that is, the distance between the tips of the locking pieces 2a and 2b.

Therefore, when the anchor metal piece 1 is rotated to be engaged with the locking pieces 2a, 2b of the window frame, even if the anchor metal piece 1 is urged to rotate, the engaging stepped portions 14a, 14b.
Collides with the tip surfaces of the window frame locking pieces 2a and 2b, so that the window frame locking pieces 2a and 2b are prevented from being excessively rotated and coming off. Further, even after the mounting in the predetermined state is completed, the engagement step portion 14 is
Since the a and 14b are in contact with the tip end surfaces of the window frame locking pieces 2a and 2b, the anchor metal fitting 10 does not shift in the indoor and outdoor directions, and the window frame locking piece 2a and the anchor metal fitting 10 are not displaced. Side engagement pieces 13a, 15a (16a) engagement margin, window frame locking piece 2b and anchor metal piece 10 side engagement piece 1
Since the amount of engagement with 3b, 15b (16b) is always the same, the engagement state is stable and the window frame 2 can be firmly held.

Hereinafter, the case where the present anchor metal fitting 10 is actually attached to window frames having different cross-sectional shapes will be described in detail. The window frame 2A shown in FIG. 4 is provided on both sides of the rear surface of the window frame along the member longitudinal direction. Each of the stepped projecting pieces has locking pieces 2a, 2b at the tip and vertical walls 2c, 2d outwardly of the locking pieces 2a, 2b. By rotating the anchor metal fitting 10 of the present invention with the axis orthogonal to the surface of the main body 11 as a rotation axis as indicated by the arrow, the locking pieces 2a,
2b, engagement receiving portions A formed on both sides of the main body 11,
Engage each B. In the engaged state in this case, as shown in FIG. 5, the engagement pieces 2a and 2b are firmly held by the engagement receiving portions A and B, and the engagement step portions 14a and 14b are engaged, respectively. Since they are engaged with each other in contact with the tip surfaces of the pieces 2a and 2b, they do not shift in the indoor / outdoor direction.

On the other hand, the window frame 2B shown in FIG. 6 is simply provided with horizontal locking pieces 2a, 2b which are opposed to each other along the longitudinal direction of the member on both sides of the rear surface of the window frame, and are independent of the window frame 2A. The distance W between the tips of the stoppers 2a and 2b and the thickness t thereof are common. In this case, the anchor metal item 10 is displaced in the indoor / outdoor direction without the engagement step portions 14a, 14b. However, as in the case described above, the anchor receiving portions A, B cause the locking pieces 2a,
2b is firmly clamped and the engaging step portion 14
Since the a and 14b are engaged with the tip surfaces of the locking pieces 2a and 2b in contact with each other, the anchor metal fitting 10 can firmly hold the window frame 2B without shifting.

[0024]

As described above in detail, according to the present invention, in the engagement receiving portion of the anchor metal member, the right and left fitting widths are made different under a predetermined condition, so that the engaging piece of the window frame is not engaged. It is possible to easily perform the mounting work when engaging the members, and in the engaged state, it is possible to firmly hold the window frame by pressing the engaging pieces so as not to shift.

Further, since the engagement step portion that abuts on the window frame locking piece is formed, the engagement is prevented from being disengaged due to excessive turning or accidental external force, and the distance between the tips of the window frame locking pieces is the same. If so, even window frames having different cross-sectional shapes can be commonly used, which brings advantages such as convenience in inventory management and construction.
