Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a sash window frame installed in a building opening,
In particular, it relates to sash window frames with flexible fixing means. [Prior Art] Anchor plates or brackets (fasteners) are used for fixing various types of sash window frames installed in the openings of buildings such as reinforced concrete. In this case, measures must be taken for each fixing means, such as protruding anchor mounting protrusions on the sash window frame, or providing thick partially built-up screws or bolt holders. .

[Problems to be Solved by the Invention] However, since it is fixedly selected in advance whether an anchor plate or a bracket is used, each sash window frame is dedicated to the fixing means, and the sash window frame As the number of types of frames increases, production and management become complicated and costs increase. The present invention was made in view of the problems of conventional sash window frames of this type, and allows the sash window frame to be fixed to both anchor plates and brackets, while ensuring sufficient workability and fixing strength. The purpose of this invention is to provide a sash window frame with flexible fixing means. [Means for Solving the Problem J] In accordance with this object, the present invention provides slide grooves for bracket fixing fittings at the same position on the outer periphery of at least one pair of opposing frames of a sash window frame, and an anchor plate for sandwiching the slide grooves front and rear. The present invention includes a structure in which the anchor mounting protrusions are provided in a stepped manner, with the former being provided inward and the latter being provided in a step-like manner; , a longitudinal sliding groove on the same position on the outer circumferential side with a narrow opening facing outward, and a pair of opposing sliding grooves sandwiching the sliding groove in the front and back and protruding outward from this in a stepped shape. The present invention relates to a sash window frame with flexible fixing means, characterized in that it comprises at least a pair of opposing frame parts each having an inverted L-shaped protrusion and an anchor attachment protrusion located at the same position on the outer periphery. This is the summary. In addition, in the present invention, the bracket fixing metal fittings refer to bolts and nuts that fasten the bracket and the frame of the sash window frame.
Used to mean a bolt or nut. [Function] In the present invention, a bracket fixing metal fitting is received and fitted to the slide groove in advance at a factory or a construction site, aligned with the bracket on the building side, and abutted against the anchor mounting protrusion. The sash window frame is fixed to the building by tightening these in the pressed state, or by rotatably attaching the anchor plate on the building side to the anchor attachment protrusion.

In addition, a bracket is used as the main fixing means and an anchor plate is used as the secondary fixing means on the upper and lower frame parts of the sash window frame, for example, so that the latter prevents the frame from sagging in the longitudinal direction. is also used. [Embodiment] The present invention will be further explained below with reference to the drawings showing the embodiment. In Figs. 1 to 3, l is a sash window with a vertical axis rotating; It comprises a vertically long rectangular sash window frame 2 made up of a frame 4, a lower frame 7, and vertical frames 8 and 9, and a door body 3 attached to the frame so as to be openable and closable. In this sash window frame 2, a slide groove 11 and an anchor attachment protrusion l2 are provided at the outer peripheral positions of the pair of opposing frame parts of the upper frame 4 and the lower frame 7, respectively, while the other pair of opposing frame parts Also on the outer periphery of each of the vertical frames 8 and 9, an anchor attachment protrusion (not shown) is provided which is continuous with the anchor attachment protrusion l2. The upper frame 4 and the lower frame 7 are hollow and made of aluminum alloy, and are integral with each other, except for attachments 5 for fixing the pivot hinge 6 for vertical axis rotation. Outer substrate lO displaced inward
The above-mentioned slide grooves 11 are provided in the upper frame 4 in a concave shape and in the lower frame 7 in a protruding shape. The slide grooves 11 are arranged along the same line on the outer periphery of the sash window frame 2, with their center positions coincident, and at the same position on the outer periphery of the upper frame 4 and the lower frame 7. Both have a narrow opening facing outward (upward or downward) so that they have an approximately inverted C-shaped cross section. As shown in FIG. 3(A), the shape of the slide groove 11 is such that the head l7 of the bracket fixing fitting, which is the bolt l6 in this example, is slidable in the longitudinal direction and is rotatably received and fitted. Therefore, the width in the longitudinal direction is adjusted to the distance between the two opposing sides of the bolt head l7, the depth is adjusted to its height, and the opening width is adjusted to the shaft diameter of the bolt l6. It is said that On the other hand, in the vicinity of each slide groove ll, an anchor attachment protrusion 12 consisting of a pair of 4L-shaped protrusions 13 and 14 is further provided protruding outward from the outer substrate IO, sandwiching it in the rearward direction. It has been set up. This anchor mounting protrusion l2
Also, the upper frame 4 and the lower frame 7 are provided with the same size spacing and height at the same position on the outer periphery, respectively, and are arranged with the wooden flat pieces facing in opposite directions. It is a thing. By the way, with respect to the slide groove 11, this anchor attachment protrusion 12 is provided further outward (upward or downward), and is arranged in a step-like manner with a small interval in the inner and outer directions. , the vertical piece of the inverted L-shaped protrusion l3 located on the outdoor side extends outward (upward or downward) as it is, and the outer end is bent towards the indoor side to form a bracket receiving groove l3.
5 is formed. The sash window frame 2 configured in this way is fixed to the building as follows:
For example, as shown in FIG. 1, a bracket l8 and an anchor plate 23 are used together. That is, the upper frame 4
The pair of opposing frame portions of the lower frame 7 are connected to the brackets l8 provided at the left and right ends and the anchor plate 23 between them, and the vertical frames 8 and 9, which are the other opposing frame portions, are connected to the anchor plates 2 and 3. -... are assumed to be fixed respectively. To explain how to fix this using the upper frame 4 as a representative example, 3rd [A] is an example of a location using the bracket l8. A number of bolts 16 are installed and erected so that their heads 17 can be slid in the longitudinal direction and not rotated, and are received and fitted from the end side (or a charging part cut out equally to the front and rear width) so that the positions can be adjusted freely. These bolts l6 are used to fix the upper frame 4 to a bracket l8, which is fastened with bolts 22 to the building frame 24 through elongated holes 2l so as to be freely longitudinally tightened. At this time, the bracket l8 is attached to the slide groove 1.
Since the anchor mounting protrusion 12, which is stepped in relation to 1, is also used as a bracket base,
The above-mentioned bracket receiving structure is brought into contact with this!
At the same time, a bolt l6 is inserted into a through hole l9 of the bracket 1B and tightened with a nut 20. On the other hand, FIG. 3(B) shows the anchor plate 23 attached to the bracket l.
This is an example in which the anchor plate 23 is rotated as in the conventional case and the horizontal piece of the anchor attachment protrusion l2 of the upper frame 4 is narrowed into the receiving groove. While dressing, adjust the position and attach it to the body 2.
4, and the lower frame 7 and vertical frames 8 and 9 are similarly fixed by brackets 18 or anchor plates 23. On the other hand, FIG. 4 shows an example in which the two left and right vertical frames 26 and 27 are further provided with a pair of opposing frame parts, and the same slide grooves 11 and anchor attachment protrusions l2 as described above are additionally provided on these frames. In this example, the sash window 25 is equipped with an attachment 5 for closing and closing, and a mullion 28 is installed at the middle of the left and right sides. The vertical frames 26 and 27 have the same structure as above except that the substrate 1O is single, so the same reference numerals are given and the explanation thereof will be omitted. The embodiment has been constructed as described above, but in carrying out the present invention, the bracket fixing metal fitting is replaced with a nut, and this is received and fitted into the slide groove, so that when fixing with the bracket, the bolt side It is also possible to rotate and tighten it. It is sufficient that the slide grooves and the anchor mounting protrusions are installed on at least one pair of opposing frames, and it is not necessary to always have them coexisting on other opposing frames (in addition, if a pair of vertically framed opposing frames (When making a section, the 5-sided cube is not included in this vertical frame). In addition, when fixing the sash window frame to the building side, it is not necessary to always use both the slide grooves and the anchor attachment protrusions on the pair of opposing frame parts, and it is sufficient to use one of them selectively. ．． On the other hand, as for the position of the slide groove, it is generally said that it is placed at the center of the front and back of the opposing frame where it is provided, or on the indoor side from this as in the above example, but this point is important when the sash window frame is installed. It is sufficient to determine each in relation to the It should be noted that the specific shapes and structures of the slide grooves, anchor attachment protrusions, etc. of the present invention, as well as the material and type of the sash window frame, may be variously changed as long as they do not go against the gist of the invention. Or, it is not limited to what has been explained. [Effects of the Invention] Since the present invention is constructed as described above, it has the following effects. That is, since the longitudinal sliding grooves and the anchor mounting protrusions are provided at the same position on the outer periphery of at least a pair of opposing frame parts, either the anchor plate or the bracket can be selected as the means for fixing the sash window frame. By using the sash as a window frame, it can be made flexible to suit the circumstances of each construction site, and the production and management of the sash window frame is simple and beneficial for cost reduction. Since they can be used together, by doing so, it is possible to easily and reliably prevent the occurrence of drooping and bending. In addition, since the anchor mounting protrusion is provided in a stepped manner on the outside of the slide groove, this anchor mounting protrusion can also be used as the bracket base when fixing the sash window frame with the bracket. This makes it possible to securely fasten the bracket using the bracket fixing fittings. Furthermore, since the slide groove receives and fits the bracket fixing fitting in a slidable and non-rotatable manner, and the anchor mounting protrusion is a pair of inverted L-shaped protrusions, it is easy to adjust its position with the bracket or anchor plate. It is easy to do, and the fixing work can be done easily.
