Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a glass plate connecting gasket that supports a roof member and prevents water leakage of a gasket that connects glass plates.

[0002]

[Prior art]

 The conventional gasket 20 shown in FIG. 5 has a substantially T-shaped wedge groove 21 formed along the longitudinal direction at the center of the bottom surface thereof, with flanges of H-shaped steel 23 sandwiched from both sides, and further formed on both sides of the gasket 20. The glass plates 25, 25 are fitted in the lateral grooves 24, 24, respectively.

Even if the lateral groove 24 and the glass plate 25 are connected in a close contact state, if the internal pressure is lower than the outside air pressure, a capillary phenomenon acts on the contact surface between the lateral groove 24 and the glass plate 25 to prevent rainwater. It may invade or dew water may be generated on the glass plate 25.

In order to prevent such moisture from falling into the room, gutters 26, 26 are provided below both sides of the gasket 20 to receive the above-mentioned moisture, and allow it to flow downstream along the roof slope. I am doing it.

The gutter 26 has a curved shape in which both sides of the gasket 20 are extended upward along the longitudinal direction, and the upper side thereof is open.

Therefore, the gutter 26 can receive invading water such as rainwater and dew condensation from its open portion 27, and can circulate this water on the curved bottom surface of the gutter 26.

[0007]

[Problems to be solved by the device]

 However, in the above-described gasket structure, since the wedge groove 21 is formed so as to contact the width portion of the web of the H-shaped steel 23, it is very difficult to insert the H-shaped steel having a wide flange width into the wedge groove 21. There was a problem that it was difficult.

Further, in the gasket structure as described above, water leakage may occur from the upper release portion 27 due to a pressure change in which the equal pressure between the indoor pressure and the outdoor pressure collapses, and this water content may cause internal moisture in the building. There was a problem that led to.

The present invention has been made to solve such a problem, and makes it easy to mount an H-shaped steel having a large flange width, and rainwater or the like does not enter the connection gap between the gasket and the glass plate. In addition, it is an object of the present invention to provide a glass plate connecting gasket in which a groove passage for receiving moisture such as dew condensation formed on a glass surface allows water to flow smoothly without causing a water leakage phenomenon.

[0010]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the gasket for connecting glass plates according to the present invention has a long bar-shaped rubber member having a clamping piece for clamping an H-shaped steel flange from both sides, and both sides of the rubber member. A horizontal groove is formed along the longitudinal direction of the horizontal groove for fitting a glass plate, and a wedge groove for fitting a wedge-shaped zipper is provided in the center of the upper pressing piece of these horizontal grooves. In a gasket for connecting glass plates in which a groove passage forming a hollow passage whose cover surface is detachable is formed, the width of the upper pressing piece is formed to be approximately half the width of the lower pressing surface forming the lower surface of the lateral groove. The lower end of the pressing piece has a protruding shape that curves downward along the longitudinal direction, while a protrusion along the longitudinal direction is formed in the middle of the lower pressing surface of the lateral groove, and the tip of the lower pressing surface extends in the longitudinal direction. along The curved protruding shape toward is further intended to clearance of the opposite sides of the clamping piece is formed with a margin relative to the web width of the H-shaped steel.

Further, it is preferable to form a concave groove along the longitudinal direction on the inner back side of each groove passage.

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows a part of a gasket for connecting glass plates according to an embodiment of the present invention, and is a partial sectional perspective view taken along the line AA of FIG. FIG. 2 is a partial perspective view showing a state in which the glass plate and the roof support member are connected to the gasket of FIG. FIG. 3 is a partial sectional view taken along the line BB of FIG. FIG. 4 is a plan view of a roof lighting unit using the gasket of the present invention.

As shown in FIG. 4, the glass plate connecting gasket 1 of this embodiment connects glass plates 2, 2 ... Used as roof lighting members on both sides of the gasket 1 and supports them along a roof slope. The member (H-shaped steel 3) can be supported under the gasket 1.

As shown in FIG. 1, the gasket 1 is made of a long rod-shaped rubber member, and a sandwiching piece 4 adapted to fit and support a flange 3b of an H-shaped steel 3 as a roof support member below the rubber member. 4 are formed, and the sandwiching pieces 4 and 4 are opposed to each other with a gap 5 in the center, and the gap 5 in the center is formed to be significantly wider than the thickness of the web 3a of the H-section steel 3. (See FIG. 2).

This facilitates the work of fitting the flange 3b of the H-shaped steel 3 having a large flange width into the holding groove 6 above the both-side holding pieces 4, 4.

Further, the holding groove 4 formed along the longitudinal direction on the inner back side of the groove passage 13 described later facilitates bending of the holding piece 4 downward, and holds the flange 3b of the H-shaped steel 3 in the holding groove. The work of fitting in 6 becomes easier.

Further, on both sides of the rubber member above the sandwiching pieces 4, 4, lateral grooves 8, 8 for fitting the glass plate 2 along the longitudinal direction of the rubber member are formed. These lateral grooves 8, 8 are formed in a groove width corresponding to the thickness of the glass plate 2 so that the glass plate 2 can be tightly held.

However, the width L1 of the upper pressing piece 9 of the lateral grooves 8, 8 is formed to be substantially half the width L 2 of the lower pressing surface 10 of the lateral groove 8.

The tip of the upper pressing piece 9 of each of the lateral grooves 8 and 8 has a protruding shape 9a which is curved downward along the longitudinal direction, and on the other hand, in the middle of the lower pressing surface 10 (the protruding shape 9 of the upper pressing piece 9). A protrusion 10a is provided along the longitudinal direction at a position (corresponding to a), and a protruding shape 10b curved upward along the longitudinal direction is formed at the tip of the lower pressing surface 10.

In such a configuration, when the glass plate 2 is inserted into the lateral grooves 8 and 8, it is necessary to bend the upper pressing piece 9 upward to increase the width of the lateral grooves 8 and 8. Since the width L1 of the upper pressing piece 9 is formed to be substantially half the width L2 of the lower pressing surface 10, the work of inserting the glass plate 2 can be easily performed.

Moreover, the protruding shape 9a of the tip of the upper pressing piece 9 presses the glass plate 2 downward to bring it into close contact, while the projection 10a of the lower pressing surface 10 facing this presses the glass plate 2 upward. The glass plate 2 can be pressed further upward by the protruding shape 10b of the tip of the lower pressing surface 10 to be brought into close contact.

When the glass plate 2 is fitted in the lateral grooves 8, 8 of the gasket 1 as in the present embodiment, even if the upper pressing piece 9 and the glass plate 2 are in a close contact state, the fitting is caused by the capillary phenomenon. Rainwater may enter through the gaps.

In this case, the water reaches the lower pressing surface 10 around the end of the glass plate 2 in the lateral groove 8. In the present embodiment, the water reaching the lower pressing surface 10 is first removed. It is provided with a double waterproofing means that can be blocked by the protrusion 10a in the middle of the lower pressing surface 10 and further blocked by the protruding shape 10b at the tip.

A wedge groove 12 into which a wedge-shaped zipper 11 is fitted is formed in the center of the upper pressing piece 9 of the lateral grooves 8 on both sides. When the glass plate 2 is inserted into the lateral grooves 8 and 8, the wedge groove 12 bends the upper pressing piece 9 upward so that the width of the lateral grooves 8 and 8 can be easily widened. After that, when the zipper 11 is fitted into the wedge groove 12, it becomes possible to press the upper pressing piece 9 toward the lower glass plate 2 side and bring the glass plate 2 into close contact with the lateral groove 8.

Further, in this embodiment, groove passages 13 and 13 are provided below the descending side surfaces of the lateral grooves 8 and 8 on both sides of the gasket 1, and the rising edges 14 and 13 are provided on the sides of the groove passages 13 and 13. The grooved passages 13 and 13 are covered with a hollow shape to form a hollow (forming a hollow passage 15), and the downwardly sloping covering surfaces 16 and 16 are detachably formed. The openings 17, 17 communicating with the hollow passages 15, 15 are formed.

In order to make the cover surface 16 detachable, the connecting portions 16a, 16a on both sides of the cover surface 16 may be formed thin. Then, in order to form the opening 17 in the covering surface 16, two cuts are made in the width direction at a desired position of the covering surface 16 and manually peeled off along the thin connecting portions 16a, 16a on both sides between them. Good.

In the groove passage 13 as described above, the dew condensation water generated on the glass plate 2 or the water that has entered between the lateral grooves 8 1 and 8 and the glass plate 2 (however, this water is the water inside the lateral groove 8 1) The protrusion shape 9a, the protrusion 10a, and the protrusion shape 10b are mostly blocked) are received by the covering surface 16, and the inside of the rising edge 14 of the side edge is caused to flow along the slope of the covering surface 16, and at the same time, this moisture is absorbed. It is dropped into the hollow passage 15 at the opening 17 on the way, and thereafter, the hollow passage 15 is made to flow down along the roof slope.

As described above, since the hollow passage 15 is covered with the covering surface 16, even if a pressure change occurs in the chamber, the moisture in the hollow passage 15 is smoothly distributed to the downstream without being affected by the turbulent air flow. It becomes possible to do.

The water flowing down in the hollow passage 15 is guided to the outside by the drainage means provided at the lower end of the gasket 1.

The supporting member 1 shown in FIG. 3 supports the connecting portion between the glass plates 2 and 2 connected along the roof slope, and is placed on the rising edge 14 of the groove passage 13 described above. The glass plate 2 fitted into the lateral grooves 8 of the gasket 1 can be simultaneously supported.

The support member 18 has a wide support piece 18a along the center of the U-shaped cross section, and the support pieces 18b and 18b on both sides support the glass plates 2 and 2 on both sides, respectively. A wide support piece 18a supports the edge of the glass plate 2 and holds a sealing material 19 that fills the connection gap between the glass plates 2.

[0033]

[Effect of the invention]

 As explained above, in the gasket for connecting glass plates of the present invention, since the upper pressing piece is significantly shorter than the lower pressing surface of the lateral groove, it is easy to insert the glass plate into the lateral groove. At the same time, the work of mounting on H-section steel having a wide flange becomes easy.

Further, when the glass plate is inserted into the lateral groove, water such as rainwater that has entered through the contact gap between the upper pressing piece of the lateral groove and the glass plate is blocked by the protrusion in the middle of the lower pressing surface of the lateral groove. In addition, it is possible to prevent the intrusion of water by the double waterproofing means, which is blocked by the protruding shape of the tip of the lower pressing surface.

Further, the dew condensation water generated on the glass plate can be dropped into the hollow passage at the opening of the covering surface in the groove passage, and thereafter, the inside of the hollow passage can be made to flow down along the roof slope. Since the is covered with a cover, it is possible for water in the hollow passage to smoothly flow and be discharged downstream without being affected by the pressure change generated in the room and leaking water.
