DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shaped steel sash frame for forming windows of a building, a shaped steel sash unit using the shaped steel sash frame, and a shaped steel sash composite unit combining a plurality of the shaped steel sash units. About.

[0002]

2. Description of the Related Art Heretofore, an aluminum frame material has been used as a sash window constituting a window of a building.

[0003]

However, in such an aluminum sash frame, it is necessary to make it hollow so as to secure the strength, or to make the found size and expected size relatively large. There is a problem that the accommodation of the sash is restricted, the frame material is conspicuous on the surface of the sash, the design is reduced, and a large sash cannot be formed.

For this reason, a steel sash frame having a higher strength than an aluminum sash frame has been used in some cases. However, such a steel sash frame is formed by bending or cutting a plate material or the like. Therefore, there is a problem that the production is very troublesome and the cost is high.

[0005] A first object of the present invention is to provide a shaped steel sash frame which can be reduced in finding and expected dimensions, and which can form a large sash with high strength and at low cost. Further, a second object of the present invention is to use the above-mentioned shaped steel sash frame to make it possible to reduce the findability and expected dimensions, to form a large-sized sash with high strength, and to improve on-site workability. It is an object to provide a shaped steel sash unit and a shaped steel sash composite unit.

[0006]

According to the present invention, there is provided a shaped steel sash frame comprising: a main body disposed along a prospective direction; and a protruding portion protruding from the main body in at least one direction orthogonal to the main body. An opening is formed by combining frame members made of shaped steel provided with the above, and the expected size of the main body is made larger than the found size of the protruding portion.

[0007] In the present invention, since a frame member made of shaped steel is used, the strength can be increased as compared with an aluminum sash frame.
As a result, the found size and expected size can be reduced. For this reason, the degree of freedom in fitting the sash is increased, the frame material is less noticeable on the sash surface, the design is improved, and a relatively large sash can be configured.

[0008] Further, since a shaped steel is used, the production becomes easier and the cost can be reduced as compared with a case where a steel plate is bent or cut. Furthermore, since the frame member is provided with a projection orthogonal to the main body, it is possible to easily install a wall material such as a glass plate or a window frame by using the projection, and the wall surface is correspondingly provided. The support structure for the material and the like is simplified, and the work of installing the wall material is also facilitated. In addition, since the expected size of the main body is larger than the found size of the protrusion, most of the load applied to the sash frame can be supported by the main body, and the protrusion holds the wall material such as a glass plate It can be suppressed to the size that can be made. For this reason, the frame material becomes less conspicuous on the sash surface and the design property can be further improved, and the supporting strength of the sash frame can be appropriately set by appropriately adjusting the expected size of the main body portion, and the area of the wall material becomes relatively large. Large sashes can also be constructed.

[0009] The projection size of the projecting portion of the frame member is required to be at least a minimum allowance for the projecting portion to hold the wall member disposed at the opening of the shaped steel sash frame, and is required for the main body portion. It is preferable that the size is obtained by adding a thickness necessary for obtaining a high rigidity. With such a dimension setting, it is possible to minimize the finding dimension of the projecting portion exposed on the outdoor surface of the frame material, and to make the frame material very inconspicuous on the sash surface, thereby improving the design.

Further, the expected dimensions of the main body of the frame material are the wall thickness required for the projection to hold the wall material disposed at the opening of the shaped steel sash frame, and the thickness of the main body of the frame material. It is preferable that the dimension be equal to or more than the sum of the expected size of the standardized steel ridge and the clearance required to hold the wall material between the protrusion and the ridge. With such a dimension setting, a flat steel or the like made of a general shape steel can be used as a ridge for holding a wall material such as glass with the projection of the frame material, and the cost can be reduced accordingly.

Here, the frame member is formed in a substantially T-shaped cross-section by projecting the projecting portion in two directions perpendicular to the main body portion. It is preferable that the dimensional ratio with the found size is approximately 2: 1. Depending on the size of the wall material such as a glass plate, the amount of protrusion of the projection required for holding the wall material and the supporting load required for supporting the wall material change. In other words, when the opening area of the shaped steel sash frame is increased and the size of the wall material such as a glass plate to be attached is increased, a margin required for holding the wall material so as not to come off the outdoor side (the protrusion of the protruding portion) is required. The found size) and the expected size of the main body required to support the load of the wall material are both increased. For this reason, if the dimensional ratio between the expected size of the main body portion and the found size of the protruding portion is set to approximately 2: 1, even if the size of the wall material changes, the size of each frame increases correspondingly. A sash frame that can be easily used, can optimize the strength balance between the protrusion and the main body, and is excellent in design and visibility can be formed.

Here, it is preferable that the expected size of the main body is 75 mm and the found size of the protruding portion is 38 mm. Each dimension is a value having a predetermined width including an allowable tolerance or the like. For example, each dimension has a width of about ± 1 mm from the above value. If the found size is about 38 mm, the thickness of the main body can be set to 6 mm, and about 16 mm can be secured for each of two adjacent wall materials. For this reason, the dimension which can manufacture a shape steel can be ensured as the thickness of a main-body part, and the dimension which can fully support each wall material can be ensured as an allowance in a protrusion part. In addition, if the expected size is about 75 mm, for example, about 9 mm is secured as the thickness of the projection, and when a standardized flat steel with the expected size of 38 mm or 44 mm is used as the ridge, the distance between the projection and the ridge is used. 22 for the dimensions of the glass holder
A thickness of about 28 mm can be secured, and a general wall material such as a float glass having a thickness of about 8 to 10 mm or a meshed glass having a thickness of about 10 mm can be sufficiently held. In addition, the expected dimensions
If it is about 75mm, when the frame material is used as a vertical frame, its length can be extended to about 3-4m, and it constitutes a comparatively large shaped steel sash frame installed in the open space of a building, etc. can do.

Similarly, when the frame member is formed in a substantially L-shaped cross section with the protruding portion protruding in one direction perpendicular to the main body, the expected size of the main body and the frame member are defined. It is preferable that the ratio of the protrusion to the found size is approximately 3.4: 1. Even in this case, when the wall material is held only on one side of the frame material, by using the frame material having the dimensional ratio according to the size of the wall material, the strength balance between the protruding portion and the main body portion is optimized. A sash frame excellent in design and visibility can be formed.

In this case, for example, it is preferable that the expected size of the main body is set to 75 mm, and the found size of the protrusion is set to 22 mm. Also in this case, the found size is about 22mm, so the thickness of the main body is 6mm, about 16mm can be secured as a margin for one wall material, it can be manufactured as shaped steel, and each wall material is fully supported Dimensions that can be achieved. In addition, if the expected size is about 75 mm, general wall materials such as meshed glass with a thickness of about 10 mm can be sufficiently held, and a relatively large shaped steel sash provided in the open space of buildings, etc. A frame can be configured.

[0015] Further, there is provided a protruding portion protruding in one direction,
For example, if a section steel frame member having a substantially L-shaped cross section and a projection section protruding in two directions are provided, for example, a section steel frame material having a substantially T-shaped section is prepared. For example, like a frame material around a sash, a frame material in which a wall material such as glass is disposed on only one side uses a frame material having a unidirectional protrusion, such as a middle bone of a sash. A relatively large sash having a middle bone or the like can be easily configured by using a frame member having a bidirectional projection as a frame member on which wall materials are arranged on both sides.

Here, in each of the section steel sash frames, the expected size of the main body and the found size of the projecting portion are as follows:
It is preferable that the setting is made in accordance with the standard dimensions of the general shape steel. Further, it is preferable that the thickness of each of the main body and the protruding portion is also set in accordance with the standard dimensions of the general shape steel. In such a case, for example, a commercially available shaped steel can be connected to the outer surface of the projecting portion of the frame material by welding or the like, and the design and rigidity are changed by appropriately using the commercially available shaped steel. Can be done. As the standard dimensions, for example, a dimensional system or the like defined in “JISG 3194” can be used.

[0017] The shaped steel sash unit according to the present invention comprises the above shaped steel sash frame, a wall material disposed at an opening of the shaped steel sash frame, and a frame material attached to a main body of the frame material of the shaped steel sash frame. And a ridge for sandwiching the wall material with the protruding portion. Here, as the wall material, glass, metal,
Various panel materials such as resin and stone can be used.

Since such a shaped steel sash unit can be assembled in a factory or the like in advance and a sash of a building can be formed only by installing each unit at a construction site, the on-site work can be reduced and the construction period can be shortened. Can be. Also,
Since the protruding portion is formed integrally with the frame member, the wall member can be sandwiched and attached simply by attaching the pressing edge, and the structure can be simplified and provided at a low cost.

The section steel sash unit is attached to the body section of the section steel sash frame and a frame member of the section steel sash frame, and holds a shoji or a door arranged at an opening of the section steel sash frame. A holding frame may be provided.
According to such a shaped steel sash unit, a sash having a door and a shoji can be assembled in a factory in advance, and the on-site work can be reduced. In addition, a frame material common to the shaped steel sash frame to which the wall material is attached can be used, and the cost can be reduced. Furthermore, if the holding frame is attached to the frame material, the holding frame can be covered with the protruding portion, and the appearance can be made to look as if a shoji or door is directly attached to the frame material, and the design can be improved. .

Further, the shaped steel sash unit includes a shaped steel sash frame having a plurality of openings, and each opening has:
One of a wall material and a pressing edge and a holding frame for a shoji or a door may be selected and attached. in this case,
Various sashes such as a sash to which a plurality of wall materials are attached, a sash to which a plurality of shojis and doors are attached, and a sash to which a wall material and a shoji or door are attached can be formed.

The section steel sash composite unit of the present invention is constructed by connecting two section steel sash units disposed adjacent to each other by a connecting member disposed between the main bodies of the frame members disposed adjacent to each other. You.

If a plurality of shaped steel sash units are constituted by such a plurality of shaped steel sash units, various shaped steel sashes having various sizes and configurations can be easily formed by appropriately combining the shaped steel sash units. be able to. Also,
Each shaped steel sash unit can be assembled in a factory or the like in advance, and a shaped steel sash can be constructed by simply combining the units at a construction site, so that on-site work can be reduced and the construction period can be shortened. In addition, by connecting the frame members via the connecting members, a highly rigid frame material can be formed, and when forming a large sash, it is necessary to change the type of the frame material of each shaped steel sash unit. No frame material can be used in common, and the cost can be reduced.

The section steel sash composite unit may be one in which each section steel sash unit is vertically arranged adjacent to each other to form a section steel sash of a step window, or each unit is arranged right and left adjacent to each other to form a continuous window. May be used to form the shaped steel sash.
Further, by providing a plurality of shaped steel sash units arranged vertically adjacent to each other and a shaped steel sash unit arranged adjacently with a height dimension combining these shaped steel sash units, the continuous window and the step window are provided. May be combined to form a shaped steel sash.

Further, in the section steel sash composite unit,
The connecting member is preferably a standardized general flat steel. If this flat steel is used as a connecting material, commercially available flat steels having various dimensions can be used, and a plurality of types of connecting materials having different found dimensions and expected dimensions can be prepared at low cost. Therefore, for example, adjustment of the gap size between the section steel sash units, adjustment of the rigidity by changing the expected size of the connecting member, and the like can be performed at relatively low cost and freely.

[0025]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 6 show a section steel sash 1 according to a first embodiment of the present invention. This shaped steel sash 1
Is arranged in an opening of a stairwell having a height of about 5 to 6 m and a width of about 3 to 4 m, and includes four section steel sash units 2 to 5. Therefore, the shape steel sash 1
Is composed of a composite steel sash unit.

Shaped steel sash unit 2 arranged on the lower side
Constitutes a frame member 10 forming an upper frame and a vertical frame, a frame member 12 forming a lower frame, a middle bone bridged between the vertical frames, and a middle bone arranged between the middle bone and the lower frame. And a frame material 11 to be formed. Accordingly, the frame members 10 of the upper and lower frames and the vertical frame,
12 are combined to form a section steel sash frame, and a frame member 11 serving as a middle bone forms an opening partition member. The section steel sash unit 2 has a plurality of (three) openings.

As shown in FIGS. 2 and 3, the frame member 10 includes a main body 10A arranged along the expected direction, and one direction orthogonal to the main body 10A from the outdoor end of the main body 10A. That is, it is formed to have an L-shaped cross section with the protruding portion 10B protruding in one direction along the finding direction. As shown in FIG. 4, for example, the frame 10
The expected dimension L of A is 75 mm, the found width dimension W1 of the protruding portion 10B is 22 mm, etc., and each dimension is smaller than that of a conventional aluminum frame material. The thickness Y2 of the main body 10A is 6 mm, and the thickness X1 of the protrusion 10B is 9 mm.

The frame member 11 protrudes in two directions orthogonal to the main body 11A from the outdoor end of the main body 11A arranged in the expected direction, and in two directions perpendicular to the main body 11A. And a projected portion 11B. As shown in FIG. 5, this frame material 11 also has an expected dimension L of the main body 11A of 75 mm and a protrusion 1
The found width dimension W2 of 1B is 38 mm or the like, which is smaller than the aluminum frame material. The thickness Y2 of the main body 11A is 6 mm, and the thickness X1 of the protrusion 11B is 9 mm.

Each of the frame members 10 and 11 has an expected dimension L of the main body portions 10A and 11A.
B is larger than the found dimensions W1 and W2. The dimensional ratio between L and W2 is set to approximately 2: 1.
Is about 3.4: 1. Here, each dimension value is a value having a predetermined width including an allowable tolerance or the like. For example, each dimension has a width of about ± 1 mm from the above value. Therefore, each dimension ratio also has a width before and after the ratio. For example, the dimensional ratio between L and W1 is 3.5: 1 (for example, L = 75.25 mm, W1 = 21.5
mm, etc.).

Each of the frame members 10 and 11 is a section steel formed by hot extrusion, and its surface is subjected to electrogalvanizing.
It is treated with a urethane resin paint finish on an epoxy rust-proof paint.

As shown in FIG. 2, the frame member 12 is composed of two channel members 12A combined in a box shape, and steel plates 12B attached to both indoor and outdoor surfaces.

As shown in FIG. 6, the frame members 10 to 12 are joined by welding to form a frame. Then, the frame member 10 is formed such that the protruding portion 10B is shaped
Are arranged toward the inner peripheral side of
Glass 14 as a wall material is disposed in each of the openings 12 formed.

Each of the glasses 14 has a plate-shaped ridge 15 bolted to the main bodies 10A and 11A via a backup material 16 and a sealing material 17 at the frame members 10 and 11, and projections 10B and 11B. It is sandwiched between and installed. Further, in the frame member 12, each glass 14 is sandwiched and attached between two steel plates 12 </ b> B via a backup member 16 and a sealing member 17.

Here, the pressing edge 15 has a thickness of about 16 mm, and has the same size as the margin Y16 of the protrusions 10B and 11B. Thereby, the ridge 15 is attached to the main body 10.
A, 11A, the position of the side surface facing the inner peripheral side of the sash unit 2 at the ledge 15 is
B, 11B. The expected size and mounting position of the ridge 15 are set so that the indoor side end surface of the ridge 15 is also aligned with the indoor side end surface of the main bodies 10A and 11A. More specifically, the expected dimension X3 of the ridge 15 is set to 44 mm, and the ridge 15 and each projection 1
Gap X2 where glass 14 between 0B and 11B is arranged
Is 22 mm. Therefore, as the ridge 15, a standardized flat steel (flat bar) having a cross-sectional dimension of 16 mm × 44 mm, which is generally commercially available, can be used.

The section steel sash unit 3 arranged beside the section steel sash unit 2 also has a section steel sash frame composed of an upper frame and a vertical frame composed of the frame member 10 and a lower frame composed of the frame member 12. It has the same structure as the section steel sash unit 2.

Each of the shaped steel sash units 4 and 5 arranged on the shaped steel sash units 2 and 3 includes a shaped steel sash frame in which the upper frame, the vertical frame, and the lower frame are all composed of the frame material 10. Edge 1 attached to main body 10A in the same manner as 2, 3
The glass 14 which is a wall material is held by 5 and the protrusion 10B.

The section steel sash units 2 to 5 are connected to each other via a connecting member 19. That is, between the frame members 10 adjacent to each other in each of the section steel sash units 2 to 5,
A connecting member 19 made of a steel plate is arranged along each frame member 10, and one frame member 10 is connected to the other frame member 1 via the connecting member 19.
The frame members 10 are connected by screwing the bolts to zero. Sealing material 17 is provided on both sides of the connecting material 19 inside and outside the room.
Is filled and waterproofed. As the connecting member 19, for example, a general flat steel having a cross section set to 12 mm × 50 mm is used.

Each of such shaped steel sash units 2 to 5
Are fixed to the building body 6 side of the building via angle members 7 and anchor members 8 and the like.

In this embodiment, at the factory or site, after forming each frame member 10 to 12 to form a shaped steel sash frame, the glass 14 is arranged, and the ridge 15 is fixed. The steel sash units 2 to 5 are configured. Then, these units 2 to 5 are connected to each other by a connecting member 19 and attached to the frame 6 to form the shaped steel sash 1. When the frame members 10 to 12 are combined at the factory, the glass 14 may be attached in advance at the factory or may be attached at the site.

In this embodiment, since the frame members 10 and 11 of each of the shaped steel sash units 2 to 5 are made of shaped steel, the strength of the shaped steel sash frame can be made higher than that of the aluminum sash. Accordingly, the found size and estimated size of the frame members 10 and 11 can be reduced. In particular, glass 1
4, the frame members 10 and 11 other than the glass 14 are used.
The area of the portion, that is, the opaque portion can be reduced, and the sash 1 as a whole can have a transparent design. Thus, by using the shaped steel sash frame composed of the frame members 10 and 11 made of the shaped steel, the structure and design restrictions are reduced as compared with the aluminum sash frame, and the degree of freedom of the structure and design can be increased. it can.

Further, since the frame members 10 to 12 are made of shaped steel, a large-sized fire door (window), which is difficult to realize with aluminum fittings, can be constructed, and can be used for a wider range of applications.

Since the shape steel is used for the frame members 10 and 11,
The manufacturing becomes easier and the cost can be reduced as compared with the case where the frame material is formed by bending or cutting a steel plate. In particular, if the frame members 10 and 11 are standardized and mass-produced, the production cost of the frame members 10 and 11 can be reduced due to mass production effects, and an enormous amount of processing time is required for each property by using existing shaped steel. Compared with the conventional case, the shaped steel sash 1 can be provided at a lower cost. Further, the use of the shaped steel can improve the member accuracy (dimensional accuracy) as compared with the case of bending or the like, and can improve the quality of the shaped steel sash 1 as a product. In addition, because the dimensional accuracy is improved and the molded steel is integrally molded by extrusion molding, the basic processing of the molded steel can be performed not by hand but by machining such as pressing. Costs can be reduced.

Since the rigidity of each of the frame members 10 and 11, that is, the rigidity of the section steel sash frame is high, relatively large sash units 2 to 5 can be configured and can be installed in a blow-through space or the like. In addition, a large shaped steel sash 1 can be formed by connecting the respective shaped steel sash units 2 to 5 to each other, and the sash 1 is provided in a larger opening.
Can be arranged.

When connecting the respective shaped steel sash units 2 to 5, the frame members 10 are joined and integrated by using the connecting member 19 made of a steel plate, so that the rigidity of the joined portion can be increased. By connecting the units 2 to 5, even if the sash 1 is enlarged, sufficient strength can be obtained by disposing the connecting members 19 between the frame members 10.

Since standardized general flat bars are used as the connecting members 19, commercially available flat bars of various dimensions can be used, and a plurality of types of connecting members 19 having different found dimensions and expected dimensions. Can be prepared at low cost.
For this reason, for example, adjustment of the gap size between the section steel sash units 2 to 5 and adjustment of the rigidity by changing the expected size of the connecting member 19 can be performed at a relatively low cost and freely. In particular, if the rigidity of the section steel sash 1 is adjusted by replacing the connecting member 19 with another connecting member 19 having a different expected size, the required strength required without changing the dimensions and combinations of the frame members 10 and 11 can be reduced. Can be satisfied. For this reason, it is not necessary to increase the found size and the expected size of each of the frame members 10 and 11, and the number of components can be reduced, and the deterioration of design and the like can be prevented.

Further, a plurality of shaped steel sash units 2 to 5
Constitutes a shaped steel sash (shape steel sash composite unit) 1, so that units having various sizes and shapes such as units 3 to 5 having units such as the unit 2 and units 3 to 5 are appropriately combined. This makes it possible to easily and inexpensively configure various shaped steel sashes corresponding to the building. Further, since each of the shaped steel sash units 2 to 5 can be pre-assembled in a factory or the like, the shaped steel sash 1 can be configured simply by combining the units 2 to 5 at the construction site, thereby reducing on-site work. Can shorten the construction period.

Further, the frame members 10 and 11 are provided with protrusions 10B,
Because of the provision of 11B, the wall material such as the glass 14 can be easily installed only by providing the ridge 15. The pressing edge 15 has an inner surface whose protruding portions 10B, 11 of the frame members 10, 11
B, and the indoor side end face is aligned with the indoor side edge of the frame members 10 and 11, so that no step is formed on the indoor surface or the inside and outside of the glass 14, and a good design with a unified feeling is obtained. can do.

In addition, since the estimated size L of the main bodies 10A and 11A is larger than the found dimensions W1 and W2 of the protruding parts 10B and 11B, most of the load applied to the sash frame is supported by the main bodies 10A and 11A. The protrusions 10B and 11B can be reduced to a size capable of holding a wall material such as the glass 14. For this reason, the frame members 10 and 11 are not conspicuous on the surface of the sash 1 so that the design can be further improved, and the main body portions 10A and 11A.
By appropriately adjusting the expected dimension L, the supporting strength of the sash frame can be set appropriately, and a relatively large sash having a large wall material area can be formed.

Further, since the dimensional ratio of the expected dimension L of the main body 11A of the frame member 11 and the found dimension W2 of the projection 11B is approximately 2: 1, the size of the sash frame, that is, the wall surface supported by the sash frame. Even if the size of the material changes, it is sufficient to use the frame material 11 having each size increased without changing the dimensional ratio correspondingly, and it is possible to easily cope with the protrusion 11B and the main body 11A. A sash frame that can optimize the strength balance and is also excellent in design and visibility can be configured.

Further, the projecting portions 10 of the frame members 10 and 11
The dimensions W1 and W2 of B and 11B are determined by adding a margin Y1 required to hold the glass 14 and a minimum thickness Y2 required to form the frame members 10 and 11 by hot extrusion or the like. Since the dimensions of the sash 1 are minimized, the found dimensions W1 and W2 can be minimized, and the frame members 10 and 11 can be made inconspicuous on the surface of the sash 1 to improve the design. That is, in the frame member 10, the finding dimension W1 is
Since the thickness of the main body 10A is about 6 mm,
About 16 mm can be secured as the allowance Y1 for the wall material. For this reason, the dimension which can manufacture a shape steel can be ensured as the thickness Y2 of the main body 10A, and the dimension which can sufficiently support each wall material can be ensured as the hooking allowance Y1 in the protruding portion 10B, and the finding size. W1 can be set very small, and the design can be improved.

Similarly, also in the frame member 11, the finding dimension W2 is
38 mm, the thickness Y2 of the main body 11A is 6 mm, and about 16 mm is secured as the allowance Y1 for the two adjacent wall materials. As well as securing, it is possible to secure a dimension that can sufficiently support each wall material as the allowance Y1 in the protruding portion 11B. The frame members 10 and 11 having such a dimension system are minimum necessary for forming a sash frame having a width W of about 1200 mm and a height H of 3000 to 4000 mm used for an entrance or the like. In addition, the number of types of members can be reduced, and the manufacturing cost can be reduced.

Further, the main body portions 10A of the frame members 10 and 11,
The expected dimension L of 11A is the thickness X1 required to obtain a strength capable of holding the wall materials such as the glass 14 disposed in the opening of the sash frame by the protruding portions 10B and 11B, that is, a rigidity capable of coping with the wind resistance. Body parts 10A, 11 of frame members 10, 11
Since the expected dimension X3 of the ridge 15 attached to the A and the clearance X2 required to hold the wall material between the protrusions 10B and 11B and the ridge 15 are added,
Flat steel or the like made of a general shape steel can be used as the ridge 15, and the cost can be reduced accordingly. That is, the frame material 1
Since the expected dimension L of 0, 11 is about 75 mm, the protrusion 1
Approximately 9 mm is secured as the thickness X1 of 0B and 11B, and the ridge 15
When a standardized flat steel with an expected size of 44 mm is used, a gap X2 of the glass holding portion between the protrusions 10B and 11B and the ridge 15 can be secured to about 22 mm, and the thickness 8
General wall materials such as float glass having a thickness of about 10 mm and meshed glass having a thickness of about 10 mm can be sufficiently held. In addition, if the expected dimension L of the frame members 10 and 11 is about 75 mm, when the frame members 10 and 11 are used as a vertical frame, the length dimension (height dimension of the sash frame) is 3 to 4 m.
This makes it possible to form a relatively large shaped steel sash frame provided in a stairwell of a building or the like. Also,
If the estimated size L of the frame members 10 and 11 is about 75 mm, the projected size to the indoor side can be reduced, and the indoor space can be used effectively. When the indoor is viewed from the outdoor side or the outdoor side from the indoor side, The frame members 10 and 11 hardly obstruct the vision, and the shaped steel sash 1 having excellent visibility can be configured.

The found size W of each of the frame members 10 and 11
1, W2, and the expected dimension L match the standard dimensions of the general shape steel, and therefore, for example, the projecting portions 10B,
A commercially available shaped steel can also be connected to the outer surface of 11B by welding or the like, and the design and rigidity can be changed by appropriately using a commercially available shaped steel. Further, since the thicknesses X1 and Y2 of the frame members 10 and 11 also correspond to the standard dimensions of the general shape steel, the general shape steel is connected and extended to the main body portions 10A and 11A and the protrusions 10B and 11B. It is also possible to easily and inexpensively change the dimensions of the frame members 10 and 11. That is, since the dimensional system of each of the frame members 10 and 11 is matched with the dimensional system of the existing general formwork,
Existing molds can be appropriately combined, and the shape, size, rigidity, and the like of the frame material can be changed relatively freely and inexpensively.
