Description

The present invention relates to a building that includes a sash portion on an outer peripheral wall.

BACKGROUND ART Conventionally, buildings are known that include a frame made of columns and beams and an outer peripheral wall surrounding the frame, and the outer peripheral wall is composed of an outer wall and a sash connected to the outer wall. .

In the above building, an outer peripheral beam is provided along the outer peripheral part of the floor surface of each floor. This peripheral beam is used for supporting the floor, fixing the sash and curtain wall that constitute the peripheral wall, and supporting the load thereof.

Here, in order to prevent the sash from overlapping the outer circumferential beam on the upper floor, the upper end position of the sash is set lower than the lower end position of the outer circumferential beam. A short wall plate is provided above the sash at a position corresponding to the outer circumferential beam so as to cover the outer circumferential beam (for example, see Patent Document 1). Further, the ceiling surface is set lower than the lower end of the beam on the upper floor and higher than the upper end of the glass surface of the sash (the lower end of the upper frame of the sash).

A plurality of "streets" are set in two orthogonal directions with an interval equal to an integer multiple of the planar module, the pillar 11 is set so that its center is located at the intersection of the streets, and the beam 12 (large beam) is set so that its width is The center of the direction is set to match the grid line. The other beams 12 (small beams, etc.) are also set so that the dimension between the centers of the beams 12 in the width direction is an integral multiple of the planar module.

In addition, the planar basic dimensions of the floor panel 40a that constitutes the floor (roof) 40, the wall panel 21a that constitutes the outer wall 21, and the sash portion 22 that is another component of the outer peripheral wall 20 are also compatible with the planar module. It is.

The frame 10 is composed of a main frame part 10a and a cantilever frame part 10b. The main frame part 10a includes a pillar 11 erected at the intersection of streets, a beam 12 (big beam 12a) built between two adjacent pillars 11 on the same street, and a pillar 11 and a beam 12 (big beam 12a). ), a beam 12 (large beam 12b) installed between two opposing large beams 12a or 12b, a beam 12 (small beam 12c, and a hanging cantilever 13b, which will be described later), on the tip side. In order to prevent this, a retaining beam 12d) is provided so as to be continuous with the proximal end of the cantilever beam 13b.

It is composed of etc.

The main body portions of the columns 11 are made of square steel pipes, and all columns 11 have the same external dimensions. The beams 12 (12a to 12d), the cantilever beams 13, and the nose bridge 14 (the main body portions thereof) are made of H-beam steel, and all (all items with the word "beam") have the same beam construction and width. It has dimensions.

At the joint between the column 11 and the beam 12 (large beam 12a) and the joint between the column 11 and the cantilever beam 13a, the end plate (joint piece) provided at the end of the beam 12 is connected to a predetermined position on the side of the column. The bolt holes are brought into contact with each other, and the bolt holes are aligned, and both are fastened together using high-strength bolts to rigidly connect them.

By fastening at , the cantilever beam 13b is joined so that the tip of the cantilever beam 13b does not sag.

The floor panel 40a constituting the floor 40 of the first floor is constructed so that (at least) two short sides are supported by the upper surface of the steel foundation beam 1a constructed between the cloth foundation 1 or the opposing cloth foundations 1. There is. The floor panel 40a constituting the floor 40 on the second floor is constructed so that (at least) two short sides thereof are supported by the upper surface of the beam 12 on the second floor.

A floor (roof) panel 40a constituting the floor (flat roof) 40 of the rooftop floor is constructed so that its two short sides are supported by floor support hardware attached to the web of the beam 12 of the rooftop floor. The floor support hardware supports the floor (roof) panel 40a at a position lower than the upper flange of the beam 12, and the floor (roof) panel 40a is dropped inside the beam 12. Thereby, the height of the roof surface is suppressed compared to the case where the floor (roof) panel 40a is supported by the upper surface of the beam 12.

The length dimension of the floor panel 40a that constitutes the floor of the first floor and the floor of the second floor is an integral multiple of the planar module (the dimension between the centers of the two beams 12 that support the floor panel 40a, for example, 610 mm (minimum) ~ It is set approximately 15 mm to 20 mm shorter than the 1830 mm (maximum) for filling with joint mortar. Further, the width dimension is one or two times that of the planar module (for example, 305 mm or 610 mm). On the other hand, the length and width of the floor (roof) panel 40a constituting the floor (flat roof) of the rooftop floor are set to avoid the beams 12 of the rooftop floor.

The outer peripheral wall 20 is provided along the outer periphery of the floor surface of each floor. The outer peripheral wall 20 includes an outer wall portion 21 and a sash portion 22 connected to the outer wall portion 21. The basic width dimension of the ALC panel constituting the outer wall portion 21 is set to be an integral multiple (for example, 1 or 2 times, ie, 305 mm or 610 mm) of the planar module.

Note that a dedicated wall panel with an L-shaped cross section is used at the projecting corner. The width dimension of the sash 23 constituting the sash portion 22 is set to be an integral multiple (for example, twice or three times, ie, 610 mm or 915 mm) of the planar module.

On the outer periphery of the floor surface of each floor, there is an outer circumferential beam installation area 31 in which the outer circumferential beam 12A of the upper floor is provided along the inner surface of the outer circumferential wall 20 of each floor, and an outer circumferential beam installation area 31 where the outer circumferential beam 12A of the upper floor is provided along the inner surface of the outer circumferential wall 20 of each floor. A peripheral beam non-installation area 32 is set in which the peripheral beam 12A is not provided.

The sash portion 22 is set at the tip of the cantilever frame portion 10b, and a pair of orthogonal beams 12B (post-extruded) are provided at positions corresponding to the edge portions on both sides of the sash portion 22 (on the planar module core). A cantilever beam 13a, an extended cantilever beam 13b) are installed, and a peripheral beam non-installation area 32 in which the peripheral beam 12A (nose tip beam 14) is removed is set between the pair of orthogonal beams 12B. . The length of the cantilevered pillars 13a and cantilevered beams 13b extending from the main beam 12a that constitutes the main frame section 10a is an integral multiple of the planar module (for example, 1830 mm, which is six times the planar module). There is.

The ends of the outer circumferential beam 12A (nose tip bridge 14) separated by the setting of the outer circumferential beam non-installation area 32 are supported by the tips of the pair of orthogonal beams 12B (post-exposed cantilever beam 13a, beam-extended cantilever beam 13b). , a stable structure is maintained. The floor panel 40a that constitutes the floor between the pair of orthogonal beams 12B has two short sides supported by the pair of orthogonal beams 12B.

At a position between the pair of orthogonal beams 12B and retreated from the tip (outer circumferential beam position) by an integral multiple of the plane module (for example, 610 mm, which is twice the plane module), there is a A reinforcing beam 12C is installed to form a floor and to shear-reinforce the floor surface of the cantilever frame portion 10b. By installing the reinforcing beam 12C, a peripheral beam non-installation area 32 is set, thereby integrating the structurally divided cantilever frame portion 10b.

As shown in the perspective view of FIG. 10, a restraining member 50 is installed at the tips of the pair of orthogonal beams 12B to connect the two and suppress relative displacement between the two. The restraint member 50 is made of a flat plate material, and is connected by bolts or the like so as to be horizontal to the upper end position (upper flange) of the pair of orthogonal beams 12B, where interference with the first floor sash 23 and the second floor sash 23 is minimal. has been done. The restraining member 50 in this embodiment has a cross section capable of resisting tensile force in order to function as an "opening stop" that restrains the tips of the pair of orthogonal beams 12B from separating from each other. Note that the function of suppressing the narrowing of the distance between the tips of the pair of orthogonal beams 12B is carried out by the floor panel 40a between the pair of orthogonal beams 12B sandwiched between adjacent other floor panels 40a. , the floor panel 40a also has a function as a restraining member.

The outer wall section 21 of each floor is installed corresponding to the outer circumferential beam installation area 31 of the upper floor, and the sash section 22 of each floor is installed corresponding to the outer circumferential beam non-installation area 32 of the upper floor.

The wall panel 21a constituting the outer wall portion 21 on the first floor is supported by a wall support member attached to the top surface of the cloth foundation 1, and is positioned in the extending direction on the lower end side, and is attached to the lower surface of the beam on the second floor. The position of the upper end in the exit direction is determined by the attached ruler member. In addition, the wall panel 21a constituting the outer wall portion 21 of the second floor is supported by a curtain wall support member attached to the upper surface of the beam on the second floor, and the upper end is supported by a ruler member attached to the lower surface of the beam on the roof floor. The positioning in the exit direction on the side is done. The wall panel 21a is a non-load-bearing wall (shelf wall), and is attached so as to swing when interstory deformation occurs in the frame 10 due to an earthquake or the like.

The wall panel 21a constituting the outer wall portion 21 of the first floor extends from near the top of the cloth foundation 1 to near the top of the second floor beam. Further, the wall panel 21a constituting the outer wall portion 21 on the second floor extends from near the top end of the beam on the second floor to near the top end of the beam on the roof floor.

The sash portion 22 on the first floor and the sash portion 22 on the second floor have the same width dimension and are continuously installed at the same position. In addition, the sash section 22 on each floor is composed of a single sash 23, and has approximately the same height dimension as the wall panel 21a constituting the outer wall section 21 on each floor (the height position of the lower end and the upper end ), and there are no short wall panels below the sash 23 on the first floor, between the sash 23 on the first floor and the sash 23 on the second floor, and above the sash 23 on the second floor. .

The sash 23 constituting the sash portion 22 is attached via a pair of sash support members 60. The sash 23 includes, for example, a rectangular plate-shaped glass that constitutes a glass surface 23a, and a sash frame 23b that surrounds and supports the glass.

FIG. 8 is a diagram showing the sash support member 60 in the building J. FIG. 9 is a perspective view showing the sash support member 60 alone. The sash support member 60 has a pair of vertical frames 61 extending in the vertical direction, and a hanging plate 62 fixed to each vertical frame 61. The vertical frame 61 can be made of, for example, a steel material with an L-shaped cross section. Further, the hanging plate 62 may be a rectangular flat steel member fixed to the vertical frame 61 by welding or the like. A plurality of hanging plates 62 are provided on each vertical frame 61 at predetermined intervals along the extending direction of the vertical frame 61.

In the sash section 22 on the first floor, the pair of sash support members 60 have their lower ends supported on the upper surface of the cloth foundation 1 and fixed with anchor bolts, and their upper ends on the web surface of the tip of the orthogonal beam 12B on the second floor. It is abutted and bolted. In addition, in the second floor sash section 22, the pair of sash support members 60 have their lower ends supported by the top surface of the tip of the orthogonal beam 12B on the second floor and are fixed with bolts, and their upper ends on the orthogonal beam 12B on the roof floor. The bolt is fixed by abutting against the web surface of the tip. Note that if the orthogonal beam 12B loses and the outer peripheral beam 12A wins, the sash support member 60 is fixed not to the tip of the orthogonal beam 12B but to the end edge of the outer peripheral beam 12A.

The sash 23 constituting the sash portion 22 has, for example, hooked portions (not shown) made of bolt shafts or the like at the four corners, and is hooked to the hook portions 63 of the sash support member 60. . The hooking portion 63 of the sash support member 60 has a vertically elongated hole shape or a notch shape (U-shape) open at the top. A shaped hooking portion 63a is used, and a long hole shaped hooking portion 63b is used to hook the upper hooked portion.

The work of attaching the sash 23 to the pair of vertical frames 61 is performed in the following procedure.
1. The sash 23 lifted by a lifting device or the like is moved to the installation position and then gradually lowered.
2. The lower part of the sash 23 is drawn toward the building, the lower part to be latched is latched to the U-shaped latching part 63a, and temporarily fastened with a bolt.
3. The upper side of the sash 23 is pulled toward the building (raise the sash 23 in a lying state), and the upper hooked part is hooked to the elongated hole-shaped hooking part 63b, and temporarily fixed with a bolt.
4. After adjusting the position of the sash 23, fully tighten the bolts.

When the sash portion 22 of each floor is composed of a single sash 23 as in this embodiment, the sash 23 is attached using a hanging plate 62 having only a U-shaped hanging portion 63a at the bottom and a hanging plate 62 having only a U-shaped hanging portion 63a at the bottom. A latching plate 62 having only an upper long hole-shaped latching portion 63b is used. On the other hand, when the sash section 22 of each floor is composed of a combination of a plurality of sashes 23, the U-shaped hooking section 63a and the elongated hole-like hooking section 63b provided at the connecting section of the two sashes 23 are A retaining plate 62 having a latching plate 62 is also used.

The ceiling (ceiling surface 18) of the living room that the sash section 22 faces is folded up diagonally near the sash section 22, and then folded up again into a curtain box shape to reach the interior upper end of the sash 23. There is.

In the orthogonal beam 12B disposed at a position corresponding to the side edge of the sash portion 22, a part of the lower flange 15 on the side opposite to the other orthogonal beam 12B is cut out near the tip, and the sash Interference between the interior finish and the orthogonal beam 12B when the interior upper end position of the section 22 is set higher than the lower end position of the orthogonal beam 12B is suppressed, and the interior width of the sash section 22 of the orthogonal beam 12B The effective width of the indoor side in the finished state is large. Note that a large load does not act on the tip end of the orthogonal beam 12B, which is a cantilever beam, and the cross-sectional performance is less affected by the cutout of a portion of the lower flange 15. Furthermore, interference between the orthogonal beam 12B and the vertical frame 61 is also avoided by cutting out a portion of the lower flange 15 of the orthogonal beam 12B.

The cutout of the orthogonal beam 12B is not limited to a part of the lower flange 15, but the entire lower end portion may be cut out on the tip side (sash portion 22 side). Note that the shape of the cutout may be, for example, tapered in side view, or crank (staircase) shaped.

The sash portion 22 may have a sash 23 and a shutter box above the sash 23. In that case, the upper end of the shutter box is preferably located above the lower end of the outer peripheral beam 12A. With this configuration, even if the sash is equipped with a shutter box, the upper end of the interior of the sash 23 can be placed at a higher position.

A protrusion is provided along the outer periphery of the rooftop (flat roof) surface to dam the rainwater that falls onto the rooftop (flat roof) surface, and the protrusion and the upper end surface of the second floor outer peripheral wall are covered by a drainage member 41. Hidden. As mentioned above, since the floor (roof) panel 40a is dropped inside the beam, the difference in height between the upper end of the outer peripheral wall and the upper end of the protrusion is extremely small, and as a result, the draining member 41 has a thin and sharp shape. is considered possible. With these configurations, in building J, as shown in FIG. A novel design that is divided into two parts has been realized.

As described above, in the building J of this embodiment, the sash portion 22 is arranged in the outer circumferential beam non-installation area 32 along the inner surface of the outer circumferential wall 20 where the outer circumferential beam 12A is not provided. With such a configuration, the ceiling surface 18 can be set high in the outer peripheral beam non-installation area 32 where the sash portion 22 is provided. Thereby, the upper end position of the sash 23 constituting the sash portion 22 is no longer restricted by the outer peripheral beam 12A, and the sash 23 can be provided at a required position. As a result, the indoor environment can be improved. In other words, as shown in FIG. 3, for example, setting the upper end of the sash 23 (the upper edge of the sash frame 23b) higher than the lower end of the outer peripheral beam 12A (indicated by the two-dot chain line) is advantageous for lighting. If the sash 23 can be opened and closed, it is advantageous in terms of ventilation and smoke exhaust. On the other hand, by providing the outer wall portion 21 in the outer circumferential beam installation area 31, the wall panel 21a and the like can be stably supported or fixed to the outer circumferential beam 12A along the inner surface of the outer circumferential wall 20.

In addition, in the event of a fire in an adjacent house, since the outer peripheral beam 12A is not present near the sash 23, when the outer peripheral beam 12A near the sash 23 is exposed to flames, areas not exposed to the flames are also affected ( For example, it is possible to prevent the outer wall (shelf wall) from shifting or falling off due to a decrease in the supporting force of the outer peripheral beam 12A, and it is possible to reduce damage in the event of a fire outbreak.

Further, a plurality of orthogonal beams 12B are provided on the side edges of the sash portion 22 on both sides or on the inner surface of the outer wall portion 21 adjacent to the sash portion 22. There is. With such a configuration, floor materials such as the floor panel 40a can be stably supported even in the outer circumferential beam non-installation area 32 where the outer circumferential beam 12A is not provided. Further, the sash 23 can be supported or fixed at the tip of the orthogonal beam 12B, and the sash 23 can be stably supported even in the outer peripheral beam non-installation area 32 where the outer peripheral beam 12A is not provided.

One of the pair of orthogonal beams 12B is a cantilever beam extended from a beam (large beam 12a) placed a predetermined distance back from the sash portion 22, and the tip of the outer peripheral beam 12A adjacent to the sash portion 22. is supported at the tip of the orthogonal beam 12B, which is a cantilever beam. With such a configuration, there is no need to install a support or the like below the outer peripheral beam 12A in order to stabilize the frame, and as a result, the outer wall portion 21 that constitutes the outer peripheral wall 20 can be installed without considering the positional relationship with the support or the like. , the arrangement of the sash portion 22, the heat insulating material, etc. can be determined.

A restraining member 50 for suppressing relative displacement of the plurality of orthogonal beams 12B is provided between the plurality of orthogonal beams 12B. With such a configuration, it is possible to reduce the load on the sash portion 22 due to the displacement of the tip side of the orthogonal beam 12B, and it is possible to suppress deformation of the sash 23 that constitutes the sash portion 22. In particular, when the orthogonal beams 12B are cantilever beams, the relative displacement difference between the tips of the orthogonal beams 12B that are not connected to each other tends to occur because the outer peripheral beams 12A do not exist continuously, making it difficult to install the restraining member 50. It is valid. For example, in a case where the orthogonal beam 12B, which is a cantilevered beam 13a in the fifth embodiment described later, is installed alone without being joined to another beam at its tip end, a remarkable effect is produced.

The restraining member 50 is made of a flat plate and is horizontally attached to the upper end portions of the plurality of orthogonal beams 12B. Such a configuration can make it difficult to affect the installation of the sash 23, the heat insulating material 42, etc. that constitute the sash portion 22. Furthermore, in addition to the restraining member 50 made of a flat plate serving as a restraining member that restrains the tips of the pair of orthogonal beams 12B from separating from each other, the floor panel 40a supported on the upper surface of the orthogonal beam 12A is Since it functions as a restraining member that suppresses the narrowing of the distance between the tips of the pair of orthogonal beams 12B, it is possible to more rationally and effectively suppress the relative displacement difference between the tips of the orthogonal beams 12B. can.

The orthogonal beam 12B disposed at the boundary between the sash portion 22 and the outer wall portion 21 has a lower flange 15, and a portion of the lower flange 15 on the side opposite to the other orthogonal beam 12B is cut out near the tip. It's dark. With this configuration, it is possible to prevent interference between the interior finish and the orthogonal beam 12B when the interior upper end position of the sash portion 22 is set higher than the lower end position of the orthogonal beam 12B, and to ensure a large interior width of the sash portion 22. Can be done. Further, by cutting out a portion of the lower flange 15 of the orthogonal beam 12B, interference between the orthogonal beam 12B and the vertical frame 61 can be avoided.

In the vicinity of the tip of the orthogonal beam 12B arranged at the boundary between the sash portion 22 and the outer wall portion 21, the lower end side may be cut out. Such a configuration also prevents interference between the interior finish and the orthogonal beam 12B when the upper end of the interior of the sash portion 22 is set higher than the lower end of the orthogonal beam 12B, thereby ensuring a large interior width of the sash portion 22. be able to.

The height of the upper end of the sash portion 22 is approximately equal to the height of the upper end of the outer wall portion 21 adjacent to the sash portion 22. With this configuration, there is no need for a wall material such as the short wall panel 21a above the sash portion 22, and it is possible to improve waterproof performance by reducing joints between members that may impair waterproof performance. .

The sash section 22 is installed on the top floor (second floor), the roof type of the roof floor is a flat roof, there is no wall panel above the sash section 22, and a draining member 41 is installed directly above the sash section 22. has been done. With this configuration, there is no need for a wall or the like above the sash portion 22, and it is possible to improve waterproof performance by reducing joints between members that may impair waterproof performance.

The sash part 22 is installed on the top floor (second floor), and a floor panel 40a forming the floor of the roof floor is installed so as to be dropped between the beams 12 provided on the roof floor. With this configuration, the height of the roof surface is suppressed compared to the case where the floor (roof) panel 40a is supported by the upper surface of the beam. Further, since the difference in height between the upper end of the outer peripheral wall and the upper end of the protrusion becomes extremely small, it is possible to form the draining member 41 into a thin and sharp shape.

The sash portion 22 includes a sash 23 and a shutter box provided above the sash 23, and the upper end of the shutter box is located above the lower end of the outer peripheral beam 12A. With such a configuration, even in the case of a sash with a shutter box, the upper end position of the interior of the sash 23 can be set at a higher position.

Further, the sash portion 22 is formed with the same width on the first floor and the second floor, and the sash 23 constituting the sash portion 22 on the second floor has its lower end side perpendicular to the extending direction of the sash 23. It is supported by the tip of the beam 12B or the end edge of the divided outer peripheral beam 12A. With such a configuration, the sash 23 on the upper floor can be stably supported without providing the outer peripheral beam 12A below (directly below) the sash 23 on the upper floor.

It is installed in combination with a sash 23 that straddles and reaches the upper end of the sash portion 22 on the second floor. Note that the restraining member on the second floor is omitted.

In this way, the sash part 22 is formed with the same width on the predetermined floor and the floor above it, and the atrium part 19 is adjacent to the outer peripheral beam non-installation area 32 and has no floor installed on the pair of orthogonal beams 12B. By adopting the configuration in which the outer peripheral beam is not installed, the sash can be installed so as to straddle the outer peripheral beam non-installation area 32, and the degree of freedom in the size and arrangement of the sash 23 installed in the sash portion 22 is greatly improved. In addition, the light from the sash 23, which has a larger daylighting area and can be obtained from a higher position than a general sash, can reach the living room on the lower floor through the atrium 19, which improves the indoor environment. can be further improved.

The other orthogonal beam 12B is a large beam 12a that constitutes the main frame portion 10a. The outer peripheral beam 12A on the one orthogonal beam 12B side (cantilever frame portion 10b side) is the nose tip beam 14. The outer peripheral beam 12A on the other orthogonal beam 12B side (main frame section 10a side) is a large beam 12a that constitutes the main frame section 10a.

In addition, in the third embodiment and later, the sash section 22 is provided on the first floor, and the arrangement of the outer peripheral wall on the first floor, the frame (columns, beams) and the floor panel 40a on the second floor is illustrated as an example. However, it can also be applied to the upper floors.

<Fourth embodiment>
FIG. 14 shows a fourth embodiment of the invention. The outer peripheral beam non-installation area 32 is set at the tip of the cantilever frame portion 10b. One end of one orthogonal beam 12B is supported by a large beam 12a constituting the main frame portion 10a, and the other end is supported by a column 17 erected below the tip of one orthogonal beam 12B. The other orthogonal beam 12B is a cantilever beam 13b, and is installed near the sash portion 22 on the outer wall portion 21 (at a position 305 mm from the boundary between the sash portion 22 and the outer wall portion 21 on the outer wall side).

The outer peripheral beam 12A on the one orthogonal beam 12B side is a nose bridge 14 whose one end is supported by one orthogonal beam 12B and the other end is supported by a cantilever beam 13a. The outer peripheral beam 12A on the other orthogonal beam 12B side is a cantilevered nose bridge 14 whose sash portion 22 side is extended by 305 mm from the cantilever beam 13b (orthogonal beam 12B).

At least one of the plurality of orthogonal beams 12B is disposed at the boundary between the sash portion 22 and the outer wall portion 21, and its tip portion is supported by the support column 17. With such a configuration, a stable frame can be constructed without using the cantilever beam 13b and a brace beam for reinforcing the cantilever beam 13b. Note that the support 17 may be of any type as long as it can transmit the vertical load from the orthogonal beam 12B to the frame 10 below (it can bear only the compressive force), and the cost is lower than that of adding a support beam.

<Fifth embodiment>
FIG. 15 shows a fifth embodiment of the invention. The outer peripheral beam non-installation area 32 is set at the tip of the cantilever frame portion 10b, where two sides are in contact with the main frame portion 10a.

The orthogonal beam 12B is installed at the boundary between the sash portion 22 and the outer wall portion 21 and at the connecting portion between adjacent sashes 23.

Among the orthogonal beams 12B installed at the boundary between the sash section 22 and the outer wall section 21, one end of the orthogonal beam 12B is supported by the main beam 12a that constitutes the main frame section 10a, and the other end is supported by the main frame section 10a. It is supported by the tip of a cantilever beam 13a extending from the pillar 11 constituting the pillar. Further, the other orthogonal beam 12B is a cantilever beam 13a extending from another pillar 11 constituting the main frame portion 10a. The two orthogonal beams 12B (intermediate orthogonal beams) installed at the connecting portions of adjacent sashes 23 are both cantilever beams 13b with a lower end cut out near the tip. Each of the outer peripheral beams 12A continuous to the sash portion 22 is constituted by a cantilevered beam 13a.

At least one of the plurality of orthogonal beams 12B has its tip supported by the end edge of the outer peripheral beam 12A (post cantilever 13a). With this configuration, the orthogonal beam can be installed without installing the cantilever beam 13b and the supporting beams, supports, etc. that reinforce it. Note that as the outer circumferential beam 12A that supports the tip of the orthogonal beam 12B, it is also possible to use a nose tip beam supported by a plurality of cantilevers and extended in the direction of the orthogonal beam 12B.

Moreover, the lower end side of the intermediate orthogonal beam installed at the connecting portion of two adjacent sashes 23 (the position corresponding to the abutting portion of the two sashes 23) is notched near the tip portion. With such a configuration, even if the orthogonal beam 12B (intermediate orthogonal beam) is present between two adjacent sashes 23 constituting the sash portion 22, the lower end position on the tip side of the intermediate orthogonal beam is high. Therefore, the ceiling surface 18 can be folded up continuously and high in the vicinity of the sash part 22 within the width of the sash part 22.

At the same time, the pair of arm portions 16b are bolted to the webs of the beams constituting the main frame, thereby providing a stable frame.

The corner cantilever beam 16 (main body portion 16a) has a lower end cutout near its tip. A restraining member is installed between the two pillars constituting the main frame portion 10a and the tip of the corner cantilever 16. With such a configuration, even if the sash portion 22 is installed over the two sides constituting the protruding corner portion, the lower end position on the tip side of the corner cantilever beam 16 is high, so the sash portion 22 The ceiling surface 18 can be folded up continuously in two directions in the vicinity.
