Description

The present invention relates to a structure for attaching an opening frame to a housing for attaching an aluminum sash or steel sash opening frame to an opening of a concrete housing.

When a window is formed in a concrete casing (hereinafter simply referred to as a casing), an opening is provided in the casing in advance at a position to be a window. When the opening frame of an aluminum sash or steel sash window is inserted, the opening is sized so that the outer periphery of the opening frame and the opening are separated by several centimeters.

    Installation of the opening frame to the opening of the housing is adjusted to the opening by lifting or suspending the opening frame with human power or a simple cargo handling machine into the opening, moving in the expected direction, and putting the opening frame into the opening. A wedge assembly is inserted between the lower frame and the lower part of the inner periphery of the opening, and a predetermined position of the opening frame in the opening is adjusted with this wedge to adjust the vertical position of the opening frame. The left and right positions of the opening frame are determined by moving the opening frame on the wedge assembly. At the same time, the deflection of the opening frame is corrected. Next, a wedge assembly is inserted between the outer periphery of the upper frame of the opening frame and the inner periphery of the opening facing the outer periphery. Thereby, the accommodation along the wall surface of the opening frame and the expected direction are determined. Then, the opening frame is positioned at the opening with a wedge assembly inserted between the lower frame and the upper frame of the opening frame and the inner periphery of the opening, and is temporarily fixed.

    Next, the opening frame is fixed to the housing. Various proposals have been made for fixing such as by welding and not by welding.

    The fixing method by welding is to provide a recess or a hole in the inner periphery of the opening when casting the concrete in the casing or after removing the formwork, and insert the casing fixing tool that protrudes into the opening into the recess or the hole. Embed and fix with. On the other hand, a sash anchor is attached to the outer periphery of the opening frame. And a sash anchor is match | combined with respect to a frame fixing tool, and a frame fixing tool and a sash anchor are welded.

    As a method for mechanically fixing the opening frame to the opening without using welding, there is a proposal of bolting the frame fixing tool and the sash anchor in the above.

    A recess is provided on the inner periphery of the opening without welding, and one end of the housing fixture is inserted into the recess and the other end is inserted into a recess provided in the sash anchor, and a synthetic resin adhesive is inserted into the recess and the recess. There are suggestions to fill.

As described above, after the opening frame is fixed to the housing in the opening, the wedge that has positioned the opening frame in the first step is removed. Then, an opening frame is fixed to a housing via a sash anchor and a housing fixing tool. Thereafter, the gap between the opening frame and the opening is filled with mortar.

    The inner periphery 1 b is perpendicular to the inner wall surface 1 h of the housing 1. The opening 1a has a square shape when viewed from the expected direction, and the inner periphery 1b and the outer periphery 2a of the opening frame 2 are spaced from each other by several centimeters.

(Fixing means)
The fixing means A includes a sash anchor 3, a frame fixing tool 5, and a wedge 6.

(Sash anchor)
As shown in FIGS. 1 and 2, the sash anchor 3 has an anchor attachment portion 3b attached to the outer periphery 2a of the opening frame 2, and the fixture distal end member 5a from the anchor attachment portion 3b toward the inner periphery 1b of the opening 1a of the housing 1. The anchor protrusion 3c protrudes beyond the tip 5a1 side, and the anchor tip member 3a protrudes in a prospective direction from the protrusion end of the anchor protrusion 3c toward the fixture protrusion 5c.

    The sash anchor 3 is made by cutting an aluminum extrusion mold. As shown in FIG. 1, the anchor attachment portion 3b is provided with a key-shaped portion 3b2 on the lower side of both edges of the flat plate portion 3b1, and has a guide groove 3d as a support portion. The guide groove 3d is fitted to a lip 2e for forming the groove 2b in the opening frame 2. In order to fit the sash anchor 3 to the lip 2e, the sash anchor 3 is fitted from the end of the sash frame material constituting the opening frame 2 and slid on the lip 2e.

  In the opening frame 2, the upper frame and the lower frame end are brought into contact with the back of the bottom plate of the groove 2b of the flange frame, and a tapping screw for inserting the bottom plate is screwed into the tapping hole 2b4 (the lower frame will be described later). That is, since the opening frame 2 is assembled in four directions in a frame frame win, the sash anchor 3 is inserted into the groove 2b from the frame frame end. The upper frame and the lower frame are notched slightly larger than the width of the anchor mounting portion 3b so that the sash anchor mounting portion 3b can be inserted into the groove 2b at the ends. Then, the sash anchor 3 is inserted from this notch and fitted to the lip 2e. This notch made by cutting out the lip 2e is a sash anchor first attaching method (an opening frame in which a sash anchor is first attached to a sash anchor first attaching method after first inserting an opening frame into the opening and temporarily positioning and fixing the sash anchor. Lip 2e is cut out so that the sash anchor can be inserted in the longitudinal ends of the upper frame and the lower frame.

  In the sash anchor 3 of this example, the anchor tip member 3a protrudes from the anchor protruding portion 3c toward the outside in the expected direction, and the anchor protruding portion 3c and the anchor tip member 3a form a key shape. On the other hand, the frame fixture 5 has a key shape with the fixture protrusion 5c and the fixture tip member 5a so as to engage with the key shape.

  The opening frame 2 with the sash anchor 3 attached is in the opening 1a to which the frame fixing tool 5 is fixed, and the sash anchor 3 and the frame fixing tool 5 can be engaged via the wedge 6.

  The sash anchor 3 is made by cutting an aluminum extrusion mold. This cutting is not only suitable for the fixing means A that is used in large quantities, because it simply cuts the extrusion mold material at right angles to the direction of extrusion, but the processing is simple and the cost can be kept low.

(Housing fixture)
As shown in FIG. 1, the housing fixture 5 includes a fixture attachment portion 5b fixed to the inner periphery 1b of the opening 1a, and the tip 3a1 side of the anchor tip member 3a from the fixture attachment portion 5b toward the opening frame 2. The aluminum extrusion mold material which cut | disconnected the fixture protrusion part 5c which protruded in the prospective direction toward the anchor protrusion part 3c from the protrusion end of the fixture protrusion part 5c which protruded beyond the fixing tool protrusion part 5c was cut | disconnected. .

  The fixture mounting portion 5b is flat and square. A fixing hole 5b1 is provided at each corner of the square. The anchor 7 is driven into the housing 1 through the hole 5b1. Here, as the anchor 7, a concrete pin may be driven in, or an expandable anchor (a pin is fitted in the outer cylinder, and the cone at the tip is a cylinder in a hole drilled in the frame with a concrete drill. The taper hole is expanded and fixed by hitting a pin, and the like. Alternatively, a nut may be inserted into the housing at a position where the anchor is provided, and a bolt may be screwed into the nut through the hole 5b1.

  In the case fixture 5 of this example, the fixture tip member 5a projects from the tip of the fixture projection 5c toward the inside in the expected direction. The fixture protrusion 5c and the fixture tip member 5a form a key shape.

  The anchor tip member 3a and the fixture tip member 5a are plate-like and the plate surfaces are parallel.

(Attaching the frame fixing tool to the frame)
The fixing means mounting portion 5b of the frame fixing tool 5 is brought into contact with the inner periphery 1b at the position of the fixing means A shown in FIG.

(Attaching the opening frame to the housing)
As described above, the sash anchor first attaching method or the sash anchor attaching method can be adopted. Alternatively, a part of the sash anchor can be attached in advance, and a front-end method and a retrofitting method in which the rest of the sash anchor is retrofitted can be used together.

(Mounting of the opening frame to the frame by attaching sash anchors)
In this case, the opening frame 2 is placed outside the opening 1a.

  The guide groove 3d of the sash anchor 3 is fitted into the lip 2e of the opening frame 2 and is moved along the groove 2b, and the sash anchor 3 is arranged at a position to be the fixing means A shown in FIG.

  A wedge (not shown) is inserted between the anchor mounting portion 3b and the middle high portion 2b2 of the opening frame 2 so that the sash anchor 3 does not move in the longitudinal direction along the frame material of the opening frame 2.

    Thus, the opening frame 2 to which the sash anchor 3 is attached is inserted into the opening 1a. Insert from inside the room. The opening frame 2 placed on the indoor side is moved manually or lifted or suspended by a simple cargo handling machine and moved outward in the expected direction. Then, the wedge assembly 11 is inserted between the opening 1 a and the inner periphery 1 b along the lower frame of the opening frame 2. The opening frame 2 is seated on the wedge assembly 11. At this time, the protrusion 5c and the tip member 5a of the housing fixture 5 and the protrusion 3c and the tip member 3a of the sash anchor 3 each have a key shape. Therefore, the protruding portion 5 c of the housing fixture 5 protrudes to the side closer to the opening frame 2 beyond the tip 3 a 1 side of the tip member 3 a of the sash anchor 3. Further, the protruding portion 3 c of the sash anchor 3 protrudes beyond the tip 5 a 1 side of the tip member 5 a of the housing fixture 5 to the side closer to the opening inner periphery 1 b.

  Therefore, the front end member 3a of the sash anchor 3 and the front end member 5a of the housing fixture 5 are opposed to each other in a plane parallel to each other, and the wedge 6 in FIG.

  Therefore, in the longitudinal direction of the sash frame member of the opening frame 2, the sash anchor 3 overlaps the housing fixture 5 as shown in FIG. 2. When they do not overlap, the sash anchor 3 is moved along the longitudinal direction of the sash frame member. In this example, the length in the longitudinal direction of the sash frame member of the frame fixing tool 5 is made larger than the same length of the sash anchor 3, but this may be reversed or the same length.

  Next, the sash anchor 3 is fixed to the opening frame 2 by caulking the key-shaped portion 3 b 2 of the sash anchor 3. In addition, when the attachment of the housing fixture 5 to the housing 1 and the attachment of the sash anchor 3 to the opening frame 2 are both performed with a jig, the sash anchor 3 is attached when the sash anchor 3 is attached to the opening frame 2. The positioning may be fixed to the opening frame 2.

  Next, after correcting the position of the opening frame 2 with respect to the opening 1a and the position in the expected direction of the opening frame 2, a wedge assembly is formed between the upper frame of the opening frame 2 and the inner periphery 1b of the opening 1a facing the upper frame. 11 is inserted and the opening frame 2 is temporarily fixed to the opening frame 1a.

  Next, as shown in FIG. 2, a wedge 6 is inserted between the respective end members 5 a and 3 a of the housing fixture 5 and the sash anchor 3. This is performed on the entire outer peripheral side of the opening frame 2. Thereby, the opening frame 2 is fixed to the housing 1 via the sash anchor 3, the wedge 6 and the housing fixing tool 5, and the position of the opening frame 2 with respect to the opening 1a is determined.

(Attaching to the frame to the opening frame by retrofitting a sash anchor)
The opening frame 2 placed in the room is lifted or suspended manually or by a simple cargo handling machine, moved outward in the prospective direction, and inserted into the opening 1a. Next, the wedge assembly 11 is inserted between the lower frame of the opening frame 2 and the inner periphery 1 b of the opening 1 a facing the lower frame, and the opening frame 2 is placed on the wedge assembly 11. And the positioning with respect to the opening part 1a of the opening frame 2 is performed. Thereafter, the wedge assembly 11 is inserted between the upper frame of the opening frame 2 and the inner periphery 1b of the opening 1a facing the outer periphery 2a of the upper frame, and the height of the wedge assembly 11 is increased to open the opening frame 2 It fixes with respect to the housing 1 in the opening part 1a.

  The sash anchor 3 is inserted into each frame from a cutout portion provided by cutting out the lip 2e of each frame of the opening frame 2 (the lip 2e is cut out before assembling the opening frame 2). In the case of this example, the notch portion of the lip 2e may be between the wedge assembly 11 supporting the respective frame bodies in the upper frame and the lower frame, or in the collar frame. When notching the end in the longitudinal direction, the notch length may be short.

    The sash anchor 3 in which the guide groove 3d is fitted to each lip 2e moves along each frame and is aligned with the frame fixture 5 already arranged on the frame 1. Then, the members around the guide groove 3d of the sash anchor 3 are deformed to pressurize the lip 2e to fix the sash anchor 3 to the opening frame 2. After that, it is the same as the assembly by sash anchor attaching.

(Fixing means in the lower frame)
FIG. 3 shows a mounting relationship between the lower frame and the casing in the lower frame of the opening frame 2. Only differences from the upper frame side will be described.

  The outer periphery 2a of the lower frame is descending outside the expected direction as a whole. The groove 2b opens toward the diagonally lower inner side. The bottom plate 2b5 of the groove 2b is a flat plate that goes down toward the outside in the prospective direction. A water return wall 2b6 rising from the bottom plate 2b5 is provided. An inner rail 2b7 is provided above the water return wall 2b6. An outer rail 2b9 is provided on a flat plate portion 2b8 that extends from the lower end of the bottom plate 2b5 to the outside in the expected direction. A tapping hole 2b4 is provided on the base side of each rail 2b7, 2b9. Although the two tapping holes 2b4 have different heights, the lower frame is brought into contact with the back of the bottom plate of the groove 2b of the eaves frame, and the tapping screw passing through the bottom plate is screwed in the same as the upper frame side. The inner shoji 8 and the outer shoji 9 are guided to the rails 2b7 and 2b9, respectively. However, the inner frame 8 and the outer frame 9 are removed from the opening frame 2 when the opening frame 2 is disposed in the opening 1a.

  The inner periphery 1b of the opening 1a of the housing 1 is outwardly descending in the expected direction. The frame fixing tool 5 is the same as the frame fixing tool 5 on the side to which the upper frame is attached. Therefore, the liner 13 is inserted between the attachment portion 5b of the frame fixture 5 on the lower frame side and the inner periphery 1b of the opening 1a facing the attachment portion 5b. The liner 13 is once brought into contact with the inner periphery 1b of the opening 1a and fixed to the housing 1. For this fixing, for example, a pin that passes through the liner 13 is driven into the housing 1. Next, the mounting portion 5b of the housing fixture 5 is brought into contact with the liner 13, and the anchor is driven into the hole formed by drilling the liner 13 and the housing 1 with a concrete drill through the hole 5b1 of the mounting portion 5b (illustrated).

  The sash anchor 3 is the same as the sash anchor on the upper frame side described above except that the attachment portion 3b is descending outward in the expected direction so as to follow the groove 2b.

    Next, a second embodiment of the present invention will be described.

    Since the casing 1 and the opening frame 2 are the same as those of the upper frame side of the previous embodiment, their description is omitted.

    4 is a vertical cross-sectional view of the upper frame side of the second embodiment, and FIG. 5 is a front view including a partial cross-section viewed from the perspective direction of FIG.

    As shown in the figure, the fixing tool protrusion 5c and the fixing tool tip member 5a have a key shape, and a pair of this key shape is used as a pair to fix the fixing tool tip member 5a with the tip 5a1 side facing each other, The sash anchor 3 has an anchor protrusion 3c inserted between the distal ends 5a1 of the fixture distal end member 5a, and an anchor distal end member 3a extending from the protruding end of the anchor protrusion 3c toward both sides in the expected direction. It has the wedge 6 and the partition 12 which fit between the sash anchor 3 and the housing fixture 5. FIG.

    The fixture attaching portion 5b is a rectangular plate shape, and has a hole 5b1 at a square portion thereof. The housing fixture 5 is fixed to the housing 1 by the anchor 7 in the same manner as in the first embodiment.

    In this example, as shown in FIG. 4, the key shape including the fixture protrusion 5c and the fixture tip member 5a as viewed from the longitudinal direction of the upper frame of the opening frame 2 is provided symmetrically including the fixture attachment portion 5b. is there.

    The anchor attachment portion 3b is the same as that in the first embodiment. As shown in FIG. 4, the anchor protrusion 3 c protrudes from a position that bisects the left-right direction of the anchor attachment portion 3 b. The anchor protrusion 3c passes through the position where the tip 5a1 of the fixture tip member 5a is divided into two equal parts. The protruding end of the anchor protruding portion 3c looks into the fixture mounting portion 5b. An anchor tip member 3a extending from the protruding end of the anchor protruding portion 3c toward both sides in the prospective direction is provided. The tip 3a1 of the anchor tip member 3a is looking into the fixture protrusion 5c. As illustrated, the anchor tip member 3a is at an intermediate position between the fixture tip member 5a and the fixture attachment portion 5b. The anchor tip member 3a is located at a position that bisects the space between the fixture tip member 5a and the fixture attachment portion 5b in this example.

    In the above, it can be considered that in this example, there are a pair of anchor protrusions 3c and anchor tip members 3a, and the two anchor protrusions 3c overlap.

    Due to the above configuration, the sash anchor 3 can be limitedly moved in the expected direction and in the vertical direction in FIG. 4 with respect to the frame fixture 5 at a fixed position.

    The sash anchor 3 is expected to be in the expected direction between the opposing distal ends 5a1 of the fixture distal end member 5a or between the fixed portion protruding portions 5c opposed to the distal end 3a1 of the anchor distal end member 3a. It can move in the direction.

    In the direction perpendicular to the inner circumference 1b (vertical direction in FIG. 4), the sash anchor 3 faces the anchor fixture 5 with respect to the anchor fixture 5 at a fixed position, and the anchor tip member 3a and the fixture attachment portion. 5b or between the anchor mounting portion 3b and the fixture distal end member 5a, whichever is closer. Further, the sash anchor 3 is away from the housing fixture 5 by a distance between the fixture tip member 5a and the anchor tip member 3a with respect to the housing fixture 5 at a fixed position in the direction perpendicular to the inner circumference 1b. It is movable.

    In the first embodiment, when the wedge 6 is not constructed, the sash anchor 3 can freely move inward as the opening frame 2 moves inward in the expected direction. The opening frame 2 attached at the same position as the fixing means A around the opening frame 2 is inserted into the opening 1a from the inside, and the positions of the frame fixing tool 5 and the sash anchor 3 coincide.

    In the second embodiment, even if either the sash anchor front-end method or the post-attach method is adopted, the opening frame 2 is initially opened in the state in which the opening frame 2 is accommodated in the opening portion 1a and positioned and temporarily fixed by the wedge assembly 11. In the longitudinal direction of the sash frame member of the frame 2, the sash anchor 3 is in a position completely separated from the housing fixture 5. Therefore, the guide groove 3d of the sash anchor 3 is moved by sliding on the lip 2e of the opening frame 2. And the anchor protrusion part 3c of the sash anchor 3 enters between the front-end | tips 5a1 of the fixing tool front end member 5a, and the anchor front-end | tip member 3a enters between the fixing tool attaching part 5b and the fixing tool front end member 5a. Thereby, as shown in FIG. 5, the sash anchor 3 overlaps the frame fixing tool 5 in the longitudinal direction of the sash frame member (upper frame in this example).

    In the sash anchor tip construction method, after the sash anchor 3 is arranged on the outer periphery 2a of the opening frame 2 in a state shifted from the arrangement of the frame fixture 5 fixed to the inner periphery 1b of the opening 1a, The opening frame 2 with the sash anchor 3 is inserted into the opening 1a.

    The sash anchor retrofitting method is the same as that of the first embodiment, and the sash anchor 3 is attached to the opening frame 2 through the notch of the opening frame 2 that is positioned and temporarily fixed in the opening 1a.

(Wedges and septa)
In the second embodiment, in each set of fixing means A, the sash anchor 3 is constrained so as not to move away from the housing fixture 5 and is constrained not to move in both directions of the expected direction.

    As shown in FIG. 4, in the second embodiment, the relative positions of the above-mentioned frame fixing tool 5 and the sash anchor 3 are fixed by the wedge 6 and the separation piece 12.

    Referring to FIGS. 4 and 6, the wedge 6 is an integral body having a wedge portion 6A and a piece portion 6B. Further, it has a large end surface 6k and a small end surface 6m, each parallel to the paper surface of FIG.

    The wedge portion 6A has wedge surfaces 6e and 6f that follow the expected direction.

    As shown in FIG. 4, the wedge surfaces 6e and 6f pressurize the fixture tip member 5a and the anchor tip member 3a.

    As shown in FIG. 6, a wedge surface 6g is provided at the edge on the large end surface 6k side from the large end side angle 6g1 perpendicular to the large end side corners 6e1 and 6f1 of the wedge surfaces 6e and 6f to the small end surface 6m side. .

    The surface 6h opposite to the wedge surface 6g shown in FIG. 6 is in contact with the anchor protrusion 3c as shown in FIG. At this time, the wedge surface 6g is in contact with the fixture protrusion 5c.

  The surface 6j on the side of the partition part 6B is perpendicular to the large end surface 6k and the small end surface 6m, and is parallel to the bisection surface 6PL formed by the wedge surfaces 6e and 6f. This surface 6j is parallel to the anchor mounting portion 3b. This surface 6j is in contact with the anchor mounting portion 3b.

  The partition part 6B is provided with a surface 6i parallel to the surface 6h. In the assembled state, the surface 6i is either coincident with or separated from the distal end of the fixture distal end member 5a.

  As apparent from the above description, the wedge 6 is an angle-shaped block. The wedge 6 is made by molding a synthetic resin or metal. If necessary, the meat is hollowed out.

  As shown in FIG. 4, the septum 12 has a wedge surface 12a that pressurizes the anchor tip member 3a. As shown in FIG. 5, the wedge surface 12a is one side surface of the partition 12 having a large end surface 12b and a small end surface 12c. A surface 12d of the septum 12 on the opposite side to the wedge surface 12a is a surface in contact with the anchor attachment portion 3b. The two surfaces intersecting each of these surfaces are parallel planes, which are surfaces 12e and 12f that contact the anchor protrusion 3c and the tip 5a1 of the fixture tip member 5a, respectively. That is, the septum 12 is substantially a rectangular parallelepiped with one surface as a wedge surface 12a. The partition 12 is made of the same material as the wedge 6 by a mold or the like.

  With the above configuration, after the sash anchor 3 is positioned so as to overlap the housing fixture 5 as shown in FIG. 5, the fixture protrusion 5c, the fixture tip member 5a, and the anchor projection as shown in FIG. 3c, the wedge 6 is inserted into the inside surrounded by the anchor tip member 3a. Insertion of the wedge 6 tends to push the space between the anchor tip member 3a and the fixture tip member 5a with the wedge surfaces 6e and 6f. At the position of each fixing means A in FIG. 8, the wedge 6 tries to expand between the two end members 3a, 5a, so that the vertical fixing position A is determined by the opposing fixing means A on the upper frame lower frame side. The position in the left-right direction is determined by the opposing fixing means A on the side of the flange frame, and the opening frame 2 is supported by the casing 1 in the opening 1a by the fixing means A. At the same time, the wedge surface 6g presses the fixture projection 5c and the surface 6h contacts the anchor projection 3c, so that the position of the sash anchor 3 in the expected direction relative to the frame fixture 5 is determined.

    Normally, the opening frame 2 does not move inward in the expected direction due to the frictional force between the wedge surfaces 6e, 6f and the two end members 3a, 5a. In this example, the wedge 6 is inserted between the anchor protrusion 3c, and the partition 12 is inserted between the anchor tip member 3a, the anchor mounting portion 3b, the anchor protrusion 3c, and the tip 5a1 of the fixture tip member 5a. At this time, the surface 12d of the partition 12 is in contact with the anchor mounting portion 3b, and the wedge surface 12a presses the anchor tip member 3a. The surface 12e is in contact with the tip 5a1 of the fixture tip member 5a, and the surface 12f is in contact with the anchor protrusion 3c. Therefore, the partition 12 is fixed to the sash anchor 3. And the sash anchor 3 cannot move to the inside of a prospective direction with respect to the frame fixing tool 5. FIG.

    In the above example, both the wedge 6 and the partition 12 can be press-fitted and held between the anchor tip member 3a and the anchor mounting portion 3b, so the sash anchor 3 to which either the wedge 6 or the partition 12 or both are attached is used. After attaching the anchor 3 to the opening frame 2, it is possible to perform an operation for matching the positions of the sash anchor 3 and the frame fixing tool 5.

    FIG. 7 is a view of the lower frame side. The description of the lower frame side will be referred to the description of the first embodiment and the description of the lower frame side.

  Although not shown in the drawing, even if a piece that fits just between the fixture protrusion 5c and the tip 3a1 of the anchor tip member 3a is used as the piece 12, the movement of the sash anchor 3 to the inside is prevented. This has the same effect as the septum 12.

    Next, an embodiment of a steel sash will be described with reference to FIG. This Example 3 is a case where the opening frame 2 is made of a steel plate. The figure shows a cross section of the upper frame. In this example, the upper frame, the lower frame, and the collar frame have the same cross section. In the third embodiment, the entrance door 10 is provided in the opening frame 2.

  The upper frame of the opening frame 2 extends in a direction perpendicular to the paper surface of FIG. The inner periphery of the opening frame 2 has a step shape, and an outer inner periphery 2f and an inner inner periphery 2g are connected by a step portion 2h. The inner material 2i of the opening frame 2 is bent upward from the inner inner periphery 2g and faces the inner side, and the upper end is an edge 2i1 obtained by cutting the plate material. The outer member 2j is bent upward from the outer inner periphery 2f. The upper end of the outer member 2j is bent to the inner side to form an outer periphery 2k. The edge of the outer periphery 2k is an edge 2k1 obtained by cutting the plate material.

    As shown in FIGS. 9 and 10, the sash anchor 3 includes an anchor attachment portion 3b attached to the outer periphery 2k of the opening frame 2, and a fixture distal end member 5a from the anchor attachment portion 3b toward the inner periphery 1b of the opening 1a of the housing 1. Similar to the first embodiment, it has an anchor protruding portion 3c that protrudes beyond the tip 5a1 side, and an anchor tip member 3a that protrudes in a prospective direction from the protruding end of the anchor protruding portion 3c toward the fixture protruding portion 5c. It is.

  A mounting portion 3g is provided at the outer end of the anchor mounting portion 3b. The inner side end of the anchor attachment portion 3b is bent, and the attachment portion 3h is provided at the bent portion.

  As shown in FIG. 10, the attachment portion 3g is provided with a cut 3g1 in parallel in the inner and outer directions, and is bent between the two cuts to form a bent piece 3g3. A flat plate piece 3g2 is provided adjacent to the bent piece 3g3 with the cut line 3g1 as a boundary. The flat piece 3g2 and the bent piece 3g3 are provided with a gap i in the direction perpendicular to the plate surface at the position of the cut 3g1.

  The attachment portion 3h is formed by bending a flat plate piece 3h2 perpendicular to the anchor attachment portion 3b by cutting the cut portion 3h1 to form a bent piece 3h3. The flat plate piece 3h2 and the bent piece 3h3 are provided with a gap j in the direction perpendicular to the plate surface at the cut position. A hole 3i is provided in the flat plate piece 3h2.

    The anchor tip member 3a and the anchor projection 3c are provided by bending from a flat anchor mounting portion 3b. The bent portion is a hole 3n.

    The housing fixture 5 is the same as that of the first embodiment, and is similarly attached to the inner periphery 1b of the housing 1.

  In this example, the opening frame 2 to which the sash anchor 3 is attached is attached to the opening 1a.

  The opening frame 2 performs an operation of attaching the sash anchor 3 in a state where the outer periphery is opened outside the opening 1a.

    Referring to FIG. 9, the sash anchor 3 is held so that the bending piece 3 h 3 of the mounting portion 3 h is slightly above the edge 2 i 1 of the inner member 2 i, and the gap of the sash anchor 3 is formed on the edge 2 k 1 of the outer periphery 2 k of the opening frame 2. When i is matched and the sash anchor 3 is pressed toward the edge 2k1, the flat piece 3g2 and the bent piece 3g3 sandwich the edge 2k1. Since the bent piece 3h3 passes over the edge 2i1 of the inner member 2i of the opening frame 2 and the flat plate piece 3h2 hits the inner member 2i, when the attachment portion 3h is pushed downward, the edge 2i1 becomes the flat piece 3h2. It is sandwiched by 3h3. Here, the small screw 14 is screwed into the female screw previously provided in the inner member 2 i through the hole 3 i shown in FIG. 10, and the sash anchor 3 is fixed to the opening frame 2.

In this example, the opening frame 2 with the sash anchor 3 is inserted into the opening 1a from the left side of FIG. 9, and the wedge 6 is fitted between the two end members 3a and 5a.
In addition, when the edge 2i1 of the inner member 2i is the opening frame 2 bent toward the edge 2k1, the embodiment before attaching the sash anchor 3 using the lip 2e can be adopted.

    11 and 12 show a fourth embodiment. The fourth embodiment is an embodiment of a steel sash corresponding to the embodiment of the aluminum sash of the second embodiment.

    Except that the opening frame 2 is provided with a lip 2m at the upper end of the inner member 2i and a groove 2n for holding an airtight packing at a stepped portion between the outer inner peripheral member 2f and the inner inner peripheral member 2g, substantially the third embodiment. The same reference numerals are used for portions corresponding to those in the third embodiment.

    The outer periphery 2k and the lip 2m of the opening frame 2 are lower in the lip 2m and have a step. Substantially following this step, the horizontal anchor attachment portion 3b is provided with a step portion 3b3 so that the external attachment portion 3m is at a high position. An inner attachment portion 3m is provided on the inner side of the anchor attachment portion 3b with respect to the outer attachment portion 3m.

    The attachment portion 3m is obtained by cutting and raising the edge of the plate material as shown in FIG. At the edges on both sides, this cut-and-raised portion is a bent piece 3m2 on the opposite side of the cut 3m1. The flat plate piece 3m3 adjacent to the bent piece 3m2 with the cut 3m1 as a boundary is offset by a step 3b3 at the flange portions on both sides. The flat plate piece 3m3 and the anchor tip member 3a are parallel planes. The cut 3m1 is on the vertical plane.

    The bent piece 3m2 and the flat plate piece 3m3 are substantially aligned at the tips. The length L of the sash anchor 3 is larger than the facing interval of the opening 2b1 of the opening frame 2. The bent piece 3m2 and the flat plate piece 3m3 are divided into upper and lower portions as shown in FIG. 11 with a notch 3m1 as a boundary, and a gap h is provided. In this gap h, the outer peripheral edge 2k1 and lip 2m of the opening frame 2 are formed. The gap h is slightly widened toward the end as viewed from the center of the sash anchor 3. Due to the gap h, the bent piece 3m2 and the flat plate piece 3m3 form a fork as shown in FIG.

    The value at the maximum end of the gap h is larger than the thickness of the edge 2k1 and the lip 2m of the opening frame 2. On the other hand, in the opening 2b1, the mounting portion 3m is smaller in the gap h than the edge 2k1 and the thickness of the lip 2m than the position corresponding to the facing interval of the opening 2b1.

    The anchor attachment portion 3b is made by sheet metal pressing. The anchor protrusion 3c and the anchor tip member 3a are welded. The anchor protrusion 3c is welded to the anchor attachment portion 3b.

    The sash anchor 3 is attached to the outer periphery 2k of the opening frame 2 at a position rotated 90 degrees from the attachment position of the sash anchor 3 to the opening frame 2 around the center perpendicular to the plate surface of the anchor attachment portion 3b. . That is, the longitudinal direction of the sash anchor 3 (the direction of the length L) is aligned with the longitudinal direction of the opening frame 2 and between the openings 2b1. Next, the sash anchor 3 is moved in a direction orthogonal to the outer periphery of the opening frame 2, and the gap h constituting the fork between the bent piece 3 m 2 and the flat plate piece 3 m 3 at both ends of the sash anchor 3 is changed to the outer periphery 2 k of the opening frame 2. Align with the edge 2k1 and lip 2m.

    Next, when the sash anchor 3 is rotated counterclockwise when the outer periphery 2k is viewed from a right angle direction from the outside of the opening frame 2, the gap h of the sash anchor 3 becomes the opening 2b1 (mouth) of the opening frame 2. Is fitted to the edge 2k1 and the lip 2m. Therefore, when the rotation further proceeds, the gap h between the bent piece 3m2 and the flat plate piece 3m3 becomes gradually narrower toward the back at the cut 3m1, and becomes 0 (zero) at the deepest. It is sandwiched between the bent piece 3m2 and the flat plate piece 3m3. The angle between the bent piece 3m2 of the gap h and the cut 3m1 of each flat plate piece 3m3 (the angle formed between the lower surface of the bent piece 3m2 and the upper surface of the flat plate piece 3m3 shown in FIGS. 11 and 12) is small, so the edge 2k1, The lip 2m is strongly pressed by the bending piece 3m2 and the flat plate piece 3m3 by the wedge action. Therefore, the sash anchor 3 can be firmly attached to the opening frame 2. At this time, the rotation angle from the beginning of the sash anchor 3 is close to 90 degrees. The position of the attachment portion 3m in the sash anchor 3 is determined so that the rotation angle does not exceed 90 degrees.

    As shown in FIG. 8, the opening frame 2 to which the sash anchor 3 is attached is inserted into the opening 1a at the position shown in FIG.

    Thereafter, the opening frame 2 is temporarily fixed by the wedge assembly 11 after being positioned with respect to the opening 1a.

  At this time, the frame fixture 5 and the sash anchor 3 are different from each other in the longitudinal direction of the frame material of the opening frame 2 as in the second embodiment. Therefore, the mounting portion 3m is hit, and the sash anchor 3 is moved in the longitudinal direction of the frame material of the opening frame 2 on the edge 2k1 and the lip 2m, and the sash anchor 3 is overlapped with the frame fixture 5. Thereafter, the wedge 6 and the septum 12 are inserted between the housing fixture 5 and the sash anchor 3.

  In this example, the outer periphery 2k and the lip 2m of the opening frame 2 can be attached to the sash anchor 2 without being cut out. Therefore, the opening frame 2 can be attached to the opening 1a by retrofitting the sash anchor 3.

    As shown in FIG. 8, the opening frame 2 is positioned and temporarily fixed by the wedge assembly 11 in the opening 1a. Then, the sash anchor 3 is inserted between the opening 1a and the outer periphery of the opening frame 2, and the sash anchor 3 is attached to the opening frame 2 in the same manner as described above. Thereafter, the sash anchor 3 is moved along the longitudinal direction of the frame material of the opening frame 2 and overlapped with the frame fixing tool 5, and the wedge 6 and the piece 12 are constructed.

  13 to 15 show the fifth embodiment. The fifth embodiment is different from the first embodiment in the direction extending from the distal ends of the protruding portions 3c and 5c of the anchor distal end member 3a and the fixture distal end member 5a. In the first embodiment, the anchor tip member 3a and the fixture tip member 5a extend in the expected direction. In this example, the anchor tip member 3a and the fixture tip member 5a are parallel to the longitudinal direction of the sash frame member of the opening frame 2 and parallel to the wall surface of the housing 1 (paper surface in FIG. 13). For this reason, although the upper frame of the opening frame 2 is represented in the case of FIG. 13, the anchor tip member 3a and the fixture tip member 5a are parallel to the longitudinal direction of the upper frame. The space S between the inner periphery 1b of the opening 1a and the outer periphery 2a of the opening frame 2 is elongated along the longitudinal direction of the upper frame of the opening frame 2. Therefore, the anchor tip member 3a and the fixture tip member 5a are parallel to the longitudinal direction of the space S.

  The sash anchor 3 has an anchor attachment portion 3b similar to that of the first embodiment, and the guide groove 3d is fitted to the lip 2e of the opening frame 2 as shown in FIG. The anchor protrusion 3c and the anchor tip member 3a are the same as in the first embodiment. The anchor protrusion 3c with respect to the anchor attachment portion 3b is located at a position obtained by rotating the anchor protrusion 3c by 90 degrees around the axis perpendicular to the state of the first embodiment.

  The same member as that of the first embodiment is used for the frame fixture 5. The frame fixing tool 5 is fixed to the inner periphery 1b of the opening 1a at a position rotated 90 degrees around the vertical axis from the state of the first embodiment.

    The wedge 6 is the same as that in the first embodiment.

  In this embodiment, for example, fixing means A is provided as shown in FIG.

  In order to provide the opening frame 2 in the opening 1a, the housing fixture 5 is fixed to the inner periphery 1b of the opening 1a as shown in FIG. Thereafter, after the position of the sash anchor 3 with respect to the housing fixture 5 of the fixing means 15 is determined as shown in FIG. 15 by either sash anchor pre-attachment or post-attachment, the anchor tip member 3a as shown by the arrow in FIG. Then, the wedge 6 is inserted between the fixing tool tip member 5a.

  According to the fifth embodiment, the opening frame 2 can have a large adjustment amount of the position in the expected direction. Since the wedge 6 can be inserted between the anchor tip member 3a and the fixture tip member 5a that can be viewed from the indoor side with a fingertip, workability is good.

(Other examples)
In each example, the upper frame was described. Regarding the upper frame, the anchor tip member 3a and the fixture tip member 5a face in the horizontal direction. (The same applies to the lower frame, and the vertical direction for the frame). However, it is not limited to the horizontal direction (vertical direction) and may be inclined. For example, the anchor tip member 3a and the fixture tip member 5a may be inclined with respect to the inner periphery 1b of the opening 1a on the paper surface of FIG. However, the inclination angle on the paper surface of FIG. 1 is an angle (referred to as a friction angle) in which the smaller value of the friction coefficient of the anchor tip member 3a or the frame fixture 5a with respect to the wedge 6 is a tangent. Limited to within.

  In FIG. 13, when the fixing means A on the upper frame and lower frame sides of the opening frame 2 are arranged symmetrically as shown in FIG. 15, the inclination of the anchor tip member 3a and the fixture tip member 5a is frictional. Although there is no restriction due to the angle, if this inclination is increased, the gap 4 between the anchor tip member 3a and the fixture tip member 5a greatly fluctuates when the position of the opening frame 2 is adjusted to the left and right. It is necessary to arrange the anchor tip member 3a and the fixture tip member 5a to the extent.

  The same applies to the second embodiment as in the case where the anchor tip member 3a and the anchor protrusion 3c of the sash anchor 3 and the frame fixture 5 are rotated 90 degrees around the vertical axis in the first embodiment. Similarly, the concept of the fifth embodiment is applied to the third and fourth embodiments of the steel sash.

  The sash anchor can be manufactured by punching, bending, or further welding a thin steel plate blank. Or since a sash anchor may cut | disconnect an aluminum extrusion mold material, it is suitable for the sash anchor used in large quantities. The frame fixture has a simple shape and can be easily arranged on the inner periphery of the opening. According to the first and third embodiments, the housing fixture can be arranged in the opening using a jig, and the sash anchor can be arranged in the opening frame using the jig, so that the work is easy, quick, and finished accurately.

    In any of the embodiments, since the relative position of the frame fixing tool and the sash anchor can be determined by the insertion length of the wedge inserted between the frame fixing tool and the sash anchor, the opening frame can be arranged in the opening. It can be done easily. In addition, by preparing wedges and various sizes of septa, the adjustment range for the opening of the opening frame can be increased.

    In any of the embodiments, the work in the narrow space between the opening and the opening frame is simply a wedge that is inserted between the housing fixture and the sash anchor, so that the work time is short and the work is easy.
