Abstract

PURPOSE:To surely prevent water-leakage by forming a draining channel of condensation liquid water adhering to glass plates separately from a draining channel of water leakage entered from a damaged part of sealant. CONSTITUTION:Condensation liquid water dropping along the side of a horizontal frame 4 from the lower parts of glass plates 5 is received by a first drain gutter 4c on the horizontal frame 4 side. A condensation liquid water draining channel draining the received condensation liquid water to the outside through a first drain gutter 3c on a vertical frame 3 side is formed. After that, water leakage entered from a damaged part of sealant 8 is received by a second drain gutter 4d on the horizontal frame 4 side, and a water leakage draining channel draining the received water leakage to the outside through a second drain gutter 3d on the vertical frame 3 side is separately formed. Accordingly, water leakage from a damaged part of sealant can be prevented from dripping into a room by overflowing the drain gutters.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toprite drainage structure which is attached to a roof portion of a building or a canopy portion of an entrance.

[0002]

BACKGROUND OF THE INVENTION Generally,
In this kind of toprite, a plurality of frames are framed in a grid pattern, and a translucent plate material is fitted into each frame,
Although there is one that is formed by sealing the peripheral edge of the translucent plate material, in such a case, dew condensation water adhering to the lower surface of the translucent plate material or water leakage from the broken part will drop into the room as it is. It is necessary to prevent that. Therefore, conventionally, the frame was formed with a drainage groove that receives the condensed water and the leaked water and discharges it to the outside, but the conventional one has a structure that drains the condensed water and the leaked water through the same drainage groove. Therefore, if there is a large amount of water leaking from the broken seal, there is a risk that water will overflow from the drain and fall into the room, which has been a problem.

[0003]

SUMMARY OF THE INVENTION The present invention was devised with the object of providing a drainage structure for toprites capable of eliminating these drawbacks in view of the above-mentioned circumstances. A vertical frame and a horizontal frame in a substantially horizontal posture in a grid pattern, and a translucent plate material is fitted into each frame, and a peripheral edge portion of the translucent plate material is sealed, The toprite receives the condensed water flowing down from the lower surface of the translucent plate material in the drain groove formed on the side surface of the horizontal frame, and receives the condensed water received through the drain groove formed on the side surface of the vertical frame. Condensed water drainage route for draining the water by the drainage channel and the drainage groove formed on the upper surface of the horizontal frame to receive the leaked water of the seal portion, and the received condensed water is passed through the drainage groove formed on the upper surface of the vertical frame. Leakage drainage It is characterized in that it has formed a path independently. Further, according to the present invention, it is possible to eliminate the inconvenience that the leaked water from the seal breakage portion overflows from the drain groove and falls into the room.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, one embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a gable-type toprite that covers an upper blow-through space of an escalator, and the toprite 1 is provided between a vertical frame 3 and a vertical frame 3 in an inclined posture which are attached in parallel to a truss type frame 2. A substantially horizontal posture horizontal frame 4, a glass plate 5 fitted in a frame formed by the frames 3 and 4, a bead 6 interposed between the glass plate 5 and the frames 3 and 4, a glass An eye plate 7 having a substantially inverted cross section which is attached to the upper ends of the frames 3 and 4 so as to overlap with the end of the plate 5, the eye plate 7 and the glass plate 5
The seal member 8 and the like are filled in the gap between the two, and the basic structure of each is the same as the conventional one.
Incidentally, 9 is a ladder for maintenance provided on the toplite 1.

The vertical frame 3 and the horizontal frame 4 are made of rectangular tubular aluminum, and the frames 3 and 4 are provided at predetermined positions (top center portion, top left and right end portions).
The protrusions 3a, 4a for attaching the eye plate 7 and the bead holding grooves 3b, 4b for fitting and holding the beads 6 are commonly formed on the left and right sides of both frames 3, 4, respectively. First drainage grooves 3c and 4c are respectively formed at the lower end portions, and both first drainage grooves 3c and 4c are communicated with each other so that the first drainage groove 3c on the vertical frame 3 side is at a lower position. That is, the dew condensation water that flows down from the lower surface of the glass plate 5 along the side surface of the horizontal frame 4 is transferred to the first drain groove 4 on the horizontal frame 4 side.
A dew condensation water drainage route is formed to receive the dew condensation water at c and discharge the dew condensation water to the outside via the first drainage groove 3c on the vertical frame 3 side.

Further, 3d and 4d are second drainage grooves formed on the upper surface portions of the vertical frame 3 and the horizontal frame 4, respectively. The second drainage grooves 3d and 4d are the convex portions 3a,
4a and the bead holding grooves 3b, 4b are formed,
The second drainage groove 3d on the vertical frame 3 side is lower than the second drainage groove 4d on the horizontal frame 4 side, and is formed as a deep groove in order to secure an allowable drainage amount as large as possible. on the other hand,
The left and right ends of the second drainage groove 4d on the side of the horizontal frame 4 are extended in a protruding manner, and the extended portions 4e penetrate through the bead mounting position to reach above the vertical frame 3 so that both frames 3, 4 The second drain grooves 3d and 4d are communicated with each other. That is, the water leaked from the damaged portion of the sealing material 8 is received by the second drainage groove 4d on the lateral frame 4 side, and the received water leak is discharged to the outside via the second drainage groove 3d on the vertical frame 3 side. The leakage water drainage route is formed independently of the above-mentioned condensation water drainage route.

In the embodiment of the present invention constructed as described above, the dew condensation water flowing down from the lower surface of the glass plate 5 along the side surface of the horizontal frame 4 is received by the first drain groove 4c on the horizontal frame 4 side. After that, while being discharged to the outside via the first drainage groove 3c on the vertical frame 3 side, the water leaking from the damaged portion of the sealing material 8 is received by the second drainage groove 4d on the horizontal frame 4 side. , Will be discharged to the outside through the second drain groove 3d on the vertical frame 3 side. That is,
Since the dew condensation water adhering to the glass plate 5 and the water leakage due to the seal breakage are configured to be discharged to the outside via separate drainage paths, it is possible to reliably discharge the water even if the temporary leakage amount is large. As a result, it is possible to surely prevent the inconvenience that the condensed water and the leaked water are drained through the same drainage groove and the water overflows from the drainage groove and falls into the room.

[0008]

In summary, since the present invention is constructed as described above, it has a drainage path for draining condensed water and leaked water, but the condensed water drainage path and the leaked water drainage path are independent. Therefore, even if there is a large amount of water leaking from the seal break portion, this water leak can be reliably drained along the dedicated drainage path. As a result, it is possible to provide an excellent toprite that does not have the inconvenience of water overflowing from the drainage channel and dropping into the room as in the conventional case in which condensed water and leaked water are combined and then drained.
