Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used, for example, to cover a roof of a three-dimensional truss type building using a three-dimensional truss such as an octaplate structure using a spherical joint with a roof panel such as glass. Regarding roof panel sash.

[0002]

2. Description of the Related Art A three-dimensional truss type building, for example, as shown in FIG. 4, forms a three-dimensional space with a base frame F by a three-dimensional truss such as an octaplate structure using a spherical joint G. It is often used for buildings called atriums or canopies that take daylight into consideration.

Therefore, the outer periphery of the base frame F, that is, the roof and side surfaces are generally covered with a roof panel P made of a transparent material such as glass, and correspond to the frame grid Fg formed on the base frame F. The roof panel sash 100 is used in combination to form a rectangular sash grid 100g.
It is designed to be attached.

As such a roof panel sash 100, there is, for example, one in which a vertical rail 101 shown in FIG. 5 and a horizontal rail 102 shown in FIG. 6 are used in combination. This conventional roof panel sash, as can be seen from FIGS. 5 and 6,
Each crosspiece 101, 102 is composed of two members, a base member 101b, 102b and a fixing member 101f, 102f. After mounting the roof panel P on the base member 101b, 102b, the fixing member 101f, 102f is covered from above. The fixing members 101f and 102f are replaced with the base members 101b and 10f.
The roof panel P is fixed by fixing it to the screw 2b with a screw, and the periphery of the connection portion is closed with a waterproof sealant 103 to provide water tightness.

Therefore, in the case of this conventional roof panel sash, the fixing member 101 for each crosspiece 101, 102 is provided.
Although the f and 102f are projected to the front surface of the roof panel P, such a structure in which the fixing members 101f and 102f are projected has a cross rail 102 which intersects particularly in the rainwater flow direction.
There is a drawback that water easily collects along the walls, it is difficult to keep away from rain, and the design is restricted.

Further, in the case of this conventional roof panel sash, since the fixing members 101f and 102f are screw-fastened, there is a problem that the designability is impaired by the screw 104 exposed on the surface, and a large number of screws are processed. Therefore, the workability is not so good.

Further, in this conventional roof panel sash, drainage channels 105 and 106 for discharging leaked water and condensed water are formed at the lower portions of the crossbars 101 and 102, respectively. The drainage joins the drainage path 105 of the vertical rail 101. For this merge, after cutting into a predetermined length, a plurality of horizontal rails 102 each have a joining hole 107 at the end thereof. Workability is poor because it is necessary to do so.

[0008]

The present invention has been made against the background of the conventional circumstances as described above, and it is necessary to prevent the horizontal crosspiece from protruding to the roof panel surface, which is an obstacle to water sweeping and a design limitation. The purpose is to provide a roof panel sash. Another object of the present invention is to provide a roof panel sash that requires less screwing work, which reduces workability. Another object of the present invention is to provide a roof panel sash having a structure that allows a drainage channel to be formed more easily.

[0009]

In order to achieve such an object, the roof panel sash according to the present invention is a combination of vertical rails and horizontal rails, each of which is formed as a single body. A pair of sandwiching grooves for sandwiching and supporting the vertical side portions of the roof panel are provided, and a pair of horizontal support rails for supporting the lateral side portions of the roof panel from below are provided in parallel and a pair of supporting grooves are provided. A mounting groove for mounting a positioning member for supporting the lateral side surface of the roof panel is provided between the stands.

In this roof panel sash, the vertical side portions of the roof panel are sandwiched and supported by holding grooves of vertical bars, and
The roof panel is assembled by supporting the lateral sides of the roof panel from below with the support of the horizontal rail, especially for the positioning regulation of the lateral side of the roof panel that is necessary for the inclined part. In addition, the lateral side surface of the roof panel is supported by the positioning member mounted in the mounting groove of the horizontal rail. Therefore, although a part of the vertical rail projects to the surface of the roof panel, the horizontal rail becomes completely hidden under the roof panel, and there is no need to perform a screwing process when assembling the roof panel.

Further, according to the present invention, in such a roof panel sash, connecting members are connected to both ends of the horizontal rail in a protruding state, and the connecting members are brought into contact with the side surfaces of the vertical rail so as to be vertically connected to the horizontal rail. I am trying to connect the crosspiece. By connecting to the vertical rail through the connecting member protruding from the end surface of the horizontal rail in this manner, the connecting member is provided between the vertical rail and the end surface of the drainage channel formed in the lower portion of the horizontal rail. Since there is a gap corresponding to the protruding amount, and this gap acts as a merging hole for the drainage channel of the horizontal rail to the drainage channel of the vertical rail, it is possible to eliminate the troublesome opening and closing work of the merging hole.

Further, according to the present invention, in such a roof panel sash, a receiving groove into which the connecting member of the horizontal rail is fitted is formed on the side surface of the vertical rail. When the connecting member of the horizontal rail is fitted into the receiving groove formed on the side surface of the vertical rail in this way, the receiving groove bears the vertical load of the horizontal rail and regulates the vertical positioning of the horizontal rail. Since it will help you, you can reduce the number of screw fastening points for the connection of the vertical rail and the horizontal rail.

[0013]

Embodiments of the present invention will be described below. The roof panel sash 1 according to the present invention includes a vertical rail 2 shown in FIG.
And the horizontal crosspiece 3 shown in FIG. 3, the vertical and horizontal crosspieces 2 and 3 are connected in the state shown in FIG. 1 to form a rectangular sash grid 1g, and the sash grid 1g is provided with a roof. A panel P is incorporated.

The vertical rail 2 is formed by connecting a base portion 11 at the lower end, a pair of vertical wall portions 12 and 12 standing upright from the base portion 11, and an intermediate portion of both vertical wall portions 12 and 12. Shelf portion 13, a support wall portion 14 that is erected on the shelf portion 13 so as to be slightly biased to one side from the center, and a support wall portion 1 at the upper end of the support wall portion 14.
4 is provided with a top plate portion 15 formed so as to intersect at right angles.

This vertical rail 2 is fixed to the base frame F (spherical joint G) via the connecting fitting 16 (FIGS. 2 and 3), and therefore the base 11 is connected to the connecting fitting 16. A bolt receiving groove 18 is provided in the center for releasing the bolt when the bolt is fastened. Further, rising edges 19, 19 are provided upright on both ends of the base portion 11,
A space between the rising edges 19 and 19 and the vertical wall portions 12 and 12 serves as a main drainage channel 21 for draining leaked water or condensed water.

Two ridges 22 are formed on the outer surface of each vertical wall portion 12.
The grooves 22 are formed in rows, and a space between the ridges 22, 22 is a receiving groove 24 for receiving a connecting member 23 of the horizontal rail 3 described later.
It is said that.

Between the upper ends of the vertical wall portions 12 and 12 and the lower surface of the left and right side portions of the top plate portion 15, a pair of holding grooves 25 and 26 for holding and supporting the vertical side portions of the roof panel P are provided. In order to sandwich the roof panel P, both vertical wall portions 12, 1
A gasket mounting portion 28 for mounting a gasket 27 for supporting the lower surface of the roof panel P, and a sealant receiving portion 31 for applying a waterproof sealant 29 adjacent to the gasket 27 are formed at the upper end of 2.

A backup material receiving ridge 32 is formed on the lower surface of the left and right side portions of the top plate 15 at a position corresponding to the gasket mounting portion 28. The backup material 33 mounted as a backup can be used as a backup to apply a waterproof sealant 34 to the upper surface of the roof panel P.

Since both of the holding grooves 25 and 26 are formed with the support wall portion 14 biased to one side as described above, one holding groove 25 is slightly deeper than the other holding groove 26. There is. This is because the roof panel P can be easily assembled between the pair of vertical bars 2 and 2 facing each other. That is, when the deep sandwiching groove 25 and the shallow sandwiching groove 26 face each other, and when the roof panel P is assembled, the vertical side portions of the roof panel P are once inserted into the deep sandwiching groove 25, and then the roof panel P is inserted. The roof panel P is assembled by shifting P and inserting the other vertical side portion into the shallow holding groove 26. The holding grooves 25, 2
The lower side of 6 is surrounded by a vertical wall portion 12, a shelf portion 13 and a supporting wall portion 14, and a sub drainage channel 3 for draining leaked water or condensed water.
It is 5.

The horizontal rail 3 is provided with a base portion 36 at the lower end, a pair of vertical wall portions 37, 37 standing upright from the base portion 36, and a shelf portion 38 connecting the upper ends of both vertical wall portions 37, 37. It has become. Similar to the vertical crosspiece 2, the base portion 36 is provided with rising edges 39, 39 at both ends thereof, and between the rising edges 39, 39 and the vertical wall portions 37, 37 drain water and condensed water. It is used as the main drainage channel 41.

On the outer surface of each vertical wall portion 37, the vertical bar 2
2 rows of ridges 42 are formed so as to correspond to the two rows of ridges 22 and 22, and a space between these ridges 42 and 42 is a mounting groove 43 for attaching the connecting member 23.

The connecting members 23 are attached in advance to both ends of the horizontal rail 3 in a projecting state and are used to connect the horizontal rail 3 to the vertical rail 2. As shown in FIG. Part 4
4, a short cross rail-side mounting portion 45, which is deviated to one side from the center, is projected in a state of intersecting at a right angle, and is formed in a deformed T shape. Regarding the attachment of the connecting member 23 to the horizontal rail 3, a basic holding force can be given by fitting the horizontal rail-side mounting portion 45 into the mounting groove 43 of the horizontal rail 3, so that a screw can be applied. The screw fastening by 46 is designed to be sufficient in one place for preventing the shift. Also, when connecting the horizontal rail 3 to the vertical rail 2 via the connecting member 23,
By fitting the vertical rail-side connecting portion 44 into the receiving groove 24 of the vertical rail 2, a basic holding force can be given.
The screwing with the screw 46 is sufficient in two places for preventing the shift.

The connecting member 23 is used to connect the horizontal rail 3 to the vertical rail 2 because the main drainage channel 4 of the horizontal rail 3 is connected.
This is because the vertical runner 2 of 1 can be easily joined to the main drainage channel 21. That is, by making the connecting member 23 in a state in which the vertical rail-side connecting portion 44 projects from the end surface of the horizontal rail 3, the end surface of the main drainage channel 41 of the horizontal rail 3 and the vertical wall portion 12 of the vertical rail 2.
And a gap S is formed between and by the thickness of the vertical rail-side connecting portion 44,
Since this gap S functions as a merging hole of the main drainage channel 41 of the horizontal rail 3 to the main drainage channel 21 of the vertical rail 2, special processing for merging is not required.

On the upper surface of the shelf portion 38, a pair of support bases 47, 47 are formed in parallel so as to support the lateral side portions of the adjacent roof panels P, P from below. A gasket mounting portion 49 for mounting a gasket 48 for supporting the lower surface of the roof panel P, and a sealant receiving portion 52 for applying a waterproof sealant 51 adjacent to the gasket 48 are provided on the upper surface of each support base 47. Has been formed.

A mounting groove 53 is provided between the support bases 47, 47, and a lateral surface of the roof panel P is supported by a positioning member 54 fitted in the mounting groove 53. This is a support required especially when the roof panel P tends to shift in the X direction indicated by the arrow in the case of an inclined portion, and the positioning member 54 has a length of about 10 cm. About two will be used per one.

The upper end of the positioning member 54 does not protrude from the upper surface of the roof panel P, and finally, when the space between the adjacent roof panels P and P is filled with the waterproof sealant 55, the waterproof property is obtained. It is in a state of being embedded under the sealant 55 for use. A cushion member 56 is interposed between the positioning member 54 and the roof panel P.

When applying the waterproof sealant 55, the sealant receiving plate 57 is inserted between the support bases 47, 47 and the roof panel P except for the portion where the positioning member 54 is placed. And both roof panels P,
A waterproof sealant 55 is applied to a portion surrounded by the side surface of P. The mounting groove 53 is also used as the sub drainage channel 58 corresponding to the sub drainage channel 35 of the vertical rail 2,
The drainage coming through the sub drainage channel 58 joins the sub drainage channel 35.

The roof panel sash 1 as described above is used by forming the rectangular sash grid 1g by the vertical bars 2 and the horizontal bars 3 as described above. It is formed by connecting the short cross rails 3 between the two in a ladder shape. Therefore, each of the vertical rails 2 and the horizontal rails 3 is on the side surface of the vertical rail 2 when the end face as shown in the drawing is the horizontal rail 3, and when the vertical rails 2 are the vertical rails 2 or each other. Although it will come into contact with other auxiliary members,
It is preferable that an appropriate elastic material is attached to the contact portion by utilizing the groove formed on the side surface of each crosspiece, and the watertightness and the like are complemented by interposing the elastic material.
