DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sash for a skylight having a space truss structure, and more particularly to a sash having a compact structure for supporting a roof panel made of a glass panel attached to a space truss structure constituting a space frame. The present invention relates to a sash for a skylight having a three-dimensional truss structure in which a light shielding film that can be opened and closed is provided in a space between the sash and the three-dimensional truss structure.

[0002]

2. Description of the Related Art In recent years, various space structures have been realized in which the exterior surface of a three-dimensional truss structure constituting a so-called space frame is covered with a special glass sash for supporting a roof panel such as a sheet glass to enhance indoor lighting. The applicant has proposed various sashes for a roof panel in which a dedicated glass sash is supported by gloves corresponding to lattice points of a three-dimensional truss structure (Japanese Patent Application Laid-Open No. 5-25893, Japanese Patent Publication No. 7-3060).
No. 2, etc.). According to these roof panel sashes, the glass panel incorporated in the skylight is firmly supported by a functionally devised sash having a sectional shape.

Further, since a sealing member such as a synthetic rubber gasket is mounted around a roof panel made of sheet glass (hereinafter, referred to as a glass panel), it is required to maintain high watertightness against wind and rain. Can be. Each sash is systematized in shape and size, and modules of each standard are manufactured at the factory. For this reason, there is an advantage that work for assembling each module is mainly performed at the site, and construction can be easily performed in a short time. Although the skylight is also called a top light, in this specification, a lighting structure in which a transparent or transmissive glass is incorporated is called a skylight.

[0004] By the way, as described above, the space structure covered with the skylight can sufficiently take in natural light therein, but depending on the application, it may be necessary to block natural light. In response to such a demand, in a conventional space structure having a space truss structure, a method of developing a light shielding film or the like along the lower chord material of the space truss and shielding natural light radiating indoors has been adopted.

In a conventional sash for a skylight,
In order to support a large glass panel on the space truss structure, two sides are supported by a cubic (vertical frame) erected in accordance with the lattice point spacing of the space truss structure, or there is no space between adjacent cubic structures at predetermined intervals. Eyes (horizontal frames) were erected to support four sides surrounded by cubicles and blind eyes.

[0006]

However, conventional skylight sashes having a light-shielding film are often designed so that the light-shielding film is developed in an internal space covered with a three-dimensional truss structure. For this reason, there is a construction problem that the number of steps for attaching the light-shielding film to the three-dimensional truss structure increases, which leads to a complicated construction. In addition, since the light-shielding film is retrofitted, the appearance from below is poor, and the expanded light-shielding film partitions a part of the internal space, so that there is a problem that a sufficient space cannot be secured near the ceiling. . Further, there is a possibility that the light shielding film may flutter or be twisted due to the airflow from the air conditioner or the like flowing near the truss, which may hinder opening and closing.

[0007] Another problem is that, in supporting the glass panel, a two-sided support for supporting the glass panel in a cubic manner has no blind members or the like crossing the water gradient direction.
There is an advantage that drainage is good, but the glass panel is easily bent. In order to suppress this bending, it is necessary to increase the plate thickness. Further, there is a problem in that the shapes of the setting block portion for holding the glass panel in the vertical frame and the horizontal frame, the self-weight receiving portion, and the rain seal member are complicated. On the other hand, in the case of four-sided support, the thickness of the glass panel can be reduced, but the blinds are arranged so as to be orthogonal to the water gradient, and the seal portion is found to be large, giving a heavy design impression. In terms of function, there is a problem that drainage at the seal portion and drainage are inferior.

Accordingly, the present invention solves the above-mentioned problems of the prior art, makes the sash for supporting the skylight glass compact, and opens and closes the space between the space truss structure and the sash. It is an object of the present invention to provide a sash for a skylight of a space truss, which allows a light shielding film to be developed.

[0009]

In order to achieve the above object, the present invention relates to a vertical frame supported at predetermined intervals on a grid point of a three-dimensional truss structure and supported by fasteners, and an adjacent vertical frame. A skylight sash of a three-dimensional truss structure having a horizontal frame erected at a predetermined interval therebetween, and supporting the periphery of the roof panel with the horizontal frame and the vertical frame to constitute a skylight, A light shielding film opening / closing structure for deploying a film body in a space between the three-dimensional truss structure and the roof panel is provided.

[0010] It is preferable that the light-shielding film is housed in a box mounted on the horizontal frame in a wound state, and is drawn out of the box so as to be developed in the space.

It is preferable that the light-shielding film is supported by the fastener and a part of the developed film is supported by an intermediate roller provided between the vertical frames.

The roof panel is preferably provided with a seam along the horizontal frame, and it is preferable to attach a blind plate for pressing the seam from an outer surface of the panel at a predetermined interval.

It is preferable that the fastener is a member whose overall height can be adjusted by adjusting an overlapping margin.

[0014]

FIG. 1 is a schematic cross-sectional perspective view of a vertical frame 20 and a horizontal frame 40 of a sash for a skylight according to the present invention in a cross-sectional view near a joint. FIG. 2 also shows a part of a motor-driven light-shielding film opening / closing structure 50 fixed to the horizontal frame 40. FIG. 2 is a sectional view mainly showing a section of the vertical frame 20. FIG. 2 also shows a partial cross section of the light-shielding film opening / closing structure 50 and a three-dimensional truss structure 1 supporting a sash for skylight.
The globe 3 as a lattice point and a part of the pipe 4 as a chord are shown.

As shown in FIG. 2, the vertical frame 20 is fixedly supported on a fastener 5 mounted on the upper end surface of the glove 3 via fixing bolts. This fastener 5
It consists of a combination of two members, an upper extruded aluminum fastener 5A and a lower extruded fastener 5B. The cross section of the lower fastener 5B has a substantially U-shaped groove shape as shown in FIG. 2, and is fixed to the glove 3 by a fixing bolt 7 via a liner ring 6 of a predetermined height on the upper end surface of the glove 3. I have. On the inner surface of the flange of the lower fastener 5B, as shown in FIGS. 2 and 3, a groove processing surface 8B in which V-shaped grooves having a fine sawtooth cross section running in the longitudinal direction of the member are distributed in a parallel streak pattern over the entire surface. Is formed. Further, a grooved surface 8A having the same shape as the grooved surface 8B is also formed on the flange outer surface of the upper fastener 5A. The V of the grooved surface 8B of the inner surface of the flange of the lower fastener 5B and the grooved surface 8A of the outer surface of the flange of the upper fastener 5A.
The upper fastener 5A and the lower fastener 5B are integrated by the engagement of the groove.

Further, both flanges are fastened by three height adjusting bolts 9 in order to reliably maintain the meshing state. The three height adjusting bolts 9 are a bolt hole of the lower fastener 5B and a long hole 11 of the upper fastener 5A shown in FIG.
And has been inserted. When the upper fastener 5A is attached to the lower fastener 5B, the overall height of the fastener 5 can be adjusted within a predetermined range by adjusting the engagement between the grooved surfaces 8A and 8B. By adjusting the height of the meshing position of this portion, the influence of bending of the member due to its own weight at the lattice point position of the space truss structure 1 can be eliminated.

The upper half of the upper fastener 5A has a T-shape, and the top surface is the support flange 13 of the vertical frame 20. A vertical frame 20 is placed and fixed on the support flange 13 via an insulating sheet 14. As the insulating sheet 14, for example, a sheet made of fluororesin represented by Teflon (registered trademark) is used. The vertical frame 20 is firmly fixed to the support flange 13 via a fixing bolt 17 and a reinforcing plate 16. The fixing bolt 17 is fastened with a nut 15 at a position below the support flange 13. The vertical frame 20 has the fastener mounting groove 2 as shown in the sectional shape in FIGS.
1 is provided on the bottom plate 22. The fixing bolt 17 and the reinforcing plate 16 are accommodated in the fastener mounting groove 21. A side wall 23 is provided upright on the upper surface of the fastener mounting groove 21 at a predetermined distance. Flanges 24 and 25 having a substantially T-shaped cross section are provided on the outer side surface of the side wall 23 so as to protrude laterally while being vertically separated from each other.

A leading guide running groove 26 is formed in a portion defined by the flange 24 and the bottom plate 22. In the leading guide running groove 26, leading guides 56 attached to both ends of a leading core material 55 described later are accommodated. When the leading guide 56 slides in the leading guide running groove 26, the movement of the leading core 55 is smoothly guided. Further, the lower end of the horizontal frame 40 is placed on the outer end surface of the flange 24. The groove defined by the flange 25 located above the flange 24 functions as a dew water drain 38. The condensed water drainage channel 38 has a horizontal frame 40.
The condensed water dropped from the end of the condensed water flow path (not shown) formed at the bottom of the vertical frame 20 along the water gradient of the vertical frame 20 to a drain gutter (not shown) provided at the lower end of the vertical frame 20. I can guide you.

The side wall 23 is reinforced by a stiffening plate 27 at an intermediate position. A support wall 28 for receiving the glass panel G is provided upright on the upper surface of the upper flange of the stiffening plate 27. An intrusion water drainage channel 29 is formed in a portion defined by the support walls 28 and the central partition 32 on both sides. The intrusion water drainage channel 29 receives drainage of rainwater or the like from the intrusion water drainage channel (not shown) of the horizontal frame 40, and further plays a role of leading to a drainage gutter (not shown) at the lower end of the vertical frame 20. Support wall 2
A claw-shaped bead receiver 30 is formed on the inner surface of 8. A bead 31 made of chloroprene rubber is fitted into the bead receiver 30. The lower end of the glass panel G is directly supported by the bead 31. A gasket 33 is fixed to an upper end position of the central partition 32.
The gasket 33 as a heat insulator plays a role of preventing a heat bridge from the cubic panel 34 exposed to the outside to the internal vertical frame 20. Further, an extension member 35 is attached to the upper end of the gasket 33 along the direction of the cubic extension. Using the elongated member 35 as a base member, a cubic board 34 is fixed to the upper end surface thereof via mounting claws. The end of the glass panel G is firmly clamped by sandwiching the gasket 33 between the front-fitting bead 31 and the cubicle plate 34 described above. As the glass panel G, a single glass, a netted glass, a heat reflection glass, a laminated glass, or the like can be appropriately used in addition to the separate type double-layer glass shown in the drawing.

A portion of the support wall 28 of the vertical frame 20 is cut out for mounting the horizontal frame 40. End 41 of horizontal frame 40
Is fixed so as to slightly protrude into the vertical frame 20 from the notch. On the bottom surface of the base box 42 of the horizontal frame 40, a film accommodating box 51 accommodating the film winding drum 52 of the light-shielding film opening / closing structure 50 is mounted via mounting hardware 66.

As shown in FIG. 4, the light-shielding film opening / closing structure 50 includes a film-receiving box 51 and a light-shielding film 5 wound around a film winding drum 52 in the film-receiving box 51.
A wire 57 for sliding the leading core material 55 in the closing direction (arrow closing direction) so as to pull out the wire 3;
And a take-up wire storage box 59 that stores a wire take-up drum 58 around which the wire 7 is wound.
The winding wire storage box 59 (not shown) has substantially the same shape as the film storage box 51, and is fixed to the bottom surface of the horizontal frame 40B at a position where the light shielding film 53 is completely pulled out.

In this embodiment, the light-shielding film opening / closing structure 50 comprises a mechanism for opening and closing the light-shielding film 53 by electric operation. Inside the film winding drum 52 and the wire winding drum 58, a tube motor (not shown) for rotating the drum, which is remotely controlled, is incorporated. The light-shielding film 53 can be opened by rotating the drum that winds the light-shielding film 53, and the wire 5
The light-shielding film 53 can be developed by being pulled out from the film winding drum 52 by rotation of the drum for winding the film 7. A power supply line and a control electric wire (not shown) for driving the motor are accommodated in the wiring space 37 of the vertical frame 20. Thereby, the electric wire can be prevented from being exposed to the outside of the vertical frame 20, and a design effect can be obtained.

FIG. 3 is a cross-sectional view showing a horizontal frame 40 fixed on the globe 3 of the space truss structure 1 and a cross section of the membrane accommodating box 51 attached to the horizontal frame 40. Horizontal frame 4
Numeral 0 denotes a vertical wall 43 erected at a predetermined distance from the upper surface of the base box 42, a stiffening panel 44 connecting the vertical walls 43, and an upper surface of the stiffening panel 44 as shown in FIG. The support partition wall 46 locked by the formed locking projection 45
And a blind eye panel 47 locked to the upper end of the support partition 46. As is clear from FIG.
Since the membrane storage box 51 is attached to the lower surface of the membrane storage box 51, the intersection of the vertical frame 20 and the horizontal frame 40 is set at a position separated by a predetermined distance from the position of the glove 3 supporting the vertical frame 20. Installation space is secured. In the same figure, the glass panel G is attached only to the left side in the figure, and the closing frame 49 is fixed to the horizontal frame 40 opposite to the position where the glass panel G is attached.

In the present embodiment, a locking projection 45 is provided on the surface of the support partition 46 in order to simplify the work of attaching the support partition 46 to the stiffening panel 44. Only by locking the locking claws of the support partition wall 46 with the locking projections 45, both are integrated. The locking claws of the support partition 46 are covered with a heat insulating sheet 48 to prevent formation of a heat bridge that causes dew condensation or the like. A locking claw 46a that can be locked to the eye panel 47 is also provided at the upper end of the support partition 46. This makes it possible to assemble each member integrally by a simple assembling operation. In addition, the support partition 4
6. Since the perforated panel 47 is locked so as to be inserted in the direction of the arrow, in the case of a sloped roof, the mounting direction of the member is determined so that the weight of the member acts on the locked portion. Further, the support partition wall 46 is fixed to the horizontal frame 40 with a set screw 68 so as not to be shifted laterally.

FIG. 4 is a schematic plan view of the skylight viewed from above. FIG. 5 schematically shows a state in which the light shielding film 53 is drawn out and covers about 3/4 of the area of the skylight. In this schematic plan view, two vertical frames 20 and a light shielding film 53 developed by being guided by the guide grooves of the vertical frames 20 are shown.

The film winding box 51 has a built-in light-shielding film winding drum 52 that is rotated by a motor as described above, and can house the wound light-shielding film 53 therein. On the other hand, a winding wire storage box 59 is fixed to the horizontal frame 40B at the other end position. The winding wire housing box 59 houses a wire winding drum 58 that winds the wire 57 wound around the leading core 55 at the tip of the light shielding film 53.

As shown in FIGS. 4 and 7, the intermediate horizontal frame 40C is located on the inner surface of the glass panel G in the general portion, and no members appear on the outer surface of the glass panel G. Therefore, only the wet sealing material 62 at the seam position of the glass panel G appears on the surface. As the wet sealant 62, a silicone sealant is preferable. Furthermore, the middle horizontal frame 40C
A blind eye panel 47 (the structure of which will be described later) is attached at a predetermined position. This blind eye panel 47
Are arranged along the horizontal frame 40 at predetermined intervals, the glass panel G can be held from the outer surface, and the holding performance of the glass panel G can be enhanced as compared with a case where the seam of the glass panel G is simply placed on the horizontal frame 40. As a result, the deflection of the glass panel G is reduced, so that the glass thickness can be reduced.

FIG. 5 is a cross-sectional view of the vertical frame 20 taken along the line VV at the mounting position of the intermediate horizontal frame 40C in FIG. The intersection of the vertical frame 20 and the intermediate horizontal frame 40C is supported on the glove 3 via the fastener 5 similarly to the support position of the vertical frame 20 shown in FIG.

Further, a state in which the leading guide 56 of the leading core 55 is accommodated in the leading guide running groove 26 is shown at the lower position of the vertical frame 20. At this time, the bearing portion 71 of the intermediate roller 70 is provided on the web 12 of the upper fastener 5A. The intermediate roller 70 is rotatably supported by the bearing 71 and is provided between the adjacent vertical frames 20. The leading core material 55 is pulled out along the leading guide running groove 26 of the vertical frame 20 by winding the wire 57, so that the light shielding film 53 is pulled out so as to pass over the intermediate roller 70. When the pulled out light-shielding film 53 is loosened and hangs down by its own weight, it is supported so as to ride on the intermediate roller 70 as shown in FIG. 6, so that the light-shielding film 53 is prevented from sagging.

FIG. 6 is a partial end view of the fastener 5 supporting the intermediate roller 70 shown in FIG. 5, as viewed from the side.
The fastener 5 is fixed on a globe 3 which is a lattice point of a space truss. This fastener 5 has a height adjustable upper fastener 5A similar to that shown in FIGS.
And a lower fastener 5B. The mounting flange 72 of the intermediate roller 70 described above is shown on the side surface of the web 12 of the upper fastener 5A. The light-shielding film 53 developed on the intermediate roller 70 is supported so as to ride thereon, and the light-shielding film 5
3 will be regulated.

FIG. 7 (a) shows a cross section of the general portion of the intermediate horizontal frame 40C and the joint structure of the glass panel G along the cross section line VIIa-VIIa of FIG. A reinforcing plate 6 slidable along the groove 43a is formed in a groove 43a formed on the inner surface of a vertical wall 43 erected on the base box 42 of the horizontal frame 40.
4 are attached to both ends of the horizontal frame 40 in the longitudinal direction. As shown in FIG. 5, the reinforcing plate 64 is slid and inserted into a groove 32a formed in the central partition wall 32 of the vertical frame 20 at a portion where the reinforcing plate 64 is engaged with the vertical frame 20.
Is fixed to a screw hole 39 provided on the outside by a stop screw 66. Thereby, the fitting portion between the horizontal frame 40 and the vertical frame 20 is firmly fixed. A base 63 made of foamed polyethylene resin or the like is provided on the central flange 65 of the horizontal frame 40 as a backup material for the wet sealing material 62 described above.
Is fixed.

FIG. 7B shows a cross section of the seam structure of the intermediate horizontal frame 40C to which the blind panel panel 47 is attached and the glass panel G along the section line VIIb-VIIb in FIG. . As shown in the drawing, a support partition 46 having the same shape as that shown in FIG. 3 is locked on the base box 42 of the horizontal frame 40. Further, a mounting claw 47a of the eye panel 47 is locked to a locking claw 46a formed at the top end of the support partition wall 46. As a result, the panel panel 47 can be firmly attached to the top end position of the support partition 46 so as to cover the joint position of the glass panel G from the outer surface. At this time, the gap between the end of the glass panel G and the end of the perforated panel 47 is filled with a wet sealing material 60 to ensure watertightness. A setting block 69 is fixed to a side surface of the support partition 46. When the end of the glass panel G is fitted into the horizontal frame 40, the setting block 69 protects the end surface of the glass panel G.

It goes without saying that the sash for skylight described above can also be used for a curtain wall constituting the outer wall surface of a building. The light-shielding film opening / closing structure that can be incorporated in the sash for the skylight may be a member having a light-shielding effect that can be incorporated in the space between the glass panel and the three-dimensional truss portion, such as a blind type in addition to the structure described above. It can be used as appropriate.

In the above description, a configuration in which a space truss structure is applied as a support structure portion and a skylight sash is mounted on the space truss structure is shown.
It is also possible to apply a frame of a steel girder structure using a conventional section steel or the like or a reinforced concrete girder structure to the supporting structure.
