Abstract

PURPOSE:To prevent any water leakage from occurring by building a gutter member, attached tight to a panel frame, into a joined part between panels. CONSTITUTION:Mutually separated drainage routes 320, 321, 322 and so on are installed radially in centering on an Apex of a domelike roof. When a panel frame, where a gutter member is attached tight, is multistagely set up in accord with this dome form, some penetrated rainwater flowing in latitude line parts 341, 351 and an oblique cross part 353 is regarded as a flow in the same direction, and thereby drainage routes 320, 321, 322 and so on flowing into longitude line parts 342, 352 and so are formed up there. With this constitution, since respective drainage routes are not interconnected with one another, any possible water leakage ascribed to a fact that the penetrated rainwater are gathered in a lower spot of the domelike roof will not occur, so that this rainwater is fed to a catchment gutter under the eaves by way of respective drainage routes.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage mechanism for a roof structure which is constructed in a dome shape as a whole by structural members arranged radially in a plan view.

[0002]

2. Description of the Related Art A roof structure called a geodesic dome has no pillars in the room and can take a large area, so that it is like an exhibition hall such as a ball stadium, a concert hall, a biological science museum, a greenhouse, and an exhibition. Widely used in buildings that require a large area. In this roof structure, structural members are arranged in a radial pattern, and a panel in which aluminum panel, acrylic panel, glass panel, or other panel material with heat insulating material sandwiched between them is fitted into a panel frame is used as the structural element. It is attached. At the part where the panels are butted against each other, a gap for rainwater to enter easily occurs. In order to prevent rainwater from entering, various sealing methods have been conventionally proposed. However, since there are many joints in the geodesic dome, infiltration of rainwater can be seen through insufficient seals, peeling parts of sealing materials, cracks, and the like. The present inventors have introduced, in Japanese Patent Application No. 1-6354, a drainage mechanism incorporating a catch pan in order to eliminate such rainwater infiltration peculiar to a geodesic dome.
In this drainage mechanism, a flat plate-shaped support metal is attached to the outside of the room at a joint position of a structural member that supports the weight of the roof, and a catch pan is further attached on the support metal. Then, the gutters provided on the roof structural member and the catch pan are attached to the support metal member in a state of being overlapped with each other. With this drainage mechanism, even if rainwater intrudes through the sealing material, the infiltration water is caught by the catch pan and is discharged to the outside through the gutter portion. Therefore, rainwater is prevented from falling into the room.

[0003]

In the drainage mechanism introduced in Japanese Patent Application No. 1-6354, a panel frame is made of an extruded material having a function as a gutter. Therefore, especially at the vertices of the side portions where a plurality of extruded materials are butted against each other, the vertices of each panel are gathered, which complicates the structure and easily causes a gap that causes rainwater intrusion. As a result, the design and construction for preventing the gap become difficult. The present invention has been devised to solve such a problem, and by using a gutter member that is separate from the panel frame, the structure is prevented from becoming complicated and there is no gap for rainwater intrusion. The purpose is to easily construct a roof structure.

[0004]

In order to achieve the object, a dome-shaped panel roof construction drainage mechanism according to the present invention has a roof surface formed by combining a plurality of triangular and trapezoidal panels whose periphery is reinforced by a panel frame. In a dome-shaped panel roof structure to be constructed, a seam formed by abutting two panels is closed with a sealing material, and one panel frame is provided below the sealing material in each space formed by adjacent panel frames. The drainage part of the upper gutter member faces the water receiving part of the lower gutter member so that the inflowing rainwater flows down to the lower part. The drainage system is provided as a plurality of drainage system channels centered on the apex of the dome-shaped panel roof and independent from each other for each meridian generated by the panel. Specifically, the parallel part,
A gutter member that integrally has a meridian line part, a water receiving part, and a drainage part,
It is fixed to the trapezoidal panel frame together with the linear gutter member that becomes the meridian. On the other hand, a gutter member integrally provided with a parallel line portion, a meridian line portion, an oblique portion, a water receiving portion and a drainage portion is fixed to the triangular panel frame. When the panel frames to which these gutter members are attached are combined in a multi-stage in accordance with the dome shape, a drainage system channel is formed below the joint of the adjacent panel frames.

Drainage channels 320, 321, 322 ...
2A, as shown in FIG. 2A, spread radially around the apex A of the dome-shaped roof and are independent of each other. The vertex A is the uppermost stage and the peripheral part is the lowermost stage. As shown in FIG. 2 (b), the gutter members at each stage are parallel to the parallel lines 341 and 351.
... and the infiltrating rainwater flowing through the oblique intersections 353, 353 ... Inflow into the meridians 342, 352 of each independent drainage system path as a flow in the same direction. Also, the free end of the oblique portion is set at a high position and the drainage portion is set at a low position, and the panel frame is attached. The water receiving portion is maintained at a height between the free ends of the parallel line portion and the crossing portion and the drainage portion (this is referred to as an intermediate position in this specification). The positional relationship of each part is adjusted by an appropriate raising member.

In the gutter member integrally provided with the parallel line part, the meridian line part, the water receiving part and the drainage part, the intersection of the parallel line part and the meridian line part is the water receiving part, and the free end of the meridian line part is the draining part. This gutter member is attached to a panel frame on three sides of a trapezoidal panel in combination with a linear gutter member that functions only as a meridian. The gutter member is not attached to one side of the remaining meridian of the trapezoidal panel, but the meridian of the gutter attached to the panel frame of the adjacent panel faces. Latitude, meridian, crossing,
In the gutter member integrally provided with the water receiving part and the draining part, the intersection of the latitude line and the meridian part is the water receiving part, and the intersection of the meridian part and the oblique intersection is the draining part. This gutter member is attached to a panel frame on three sides of a triangular panel. The gutter member is not attached to all the panel frames of the trapezoidal panel and the triangular panel. For example, when a gutter member is attached to one of the panel frames facing each other,
Do not attach the gutter member to the other panel frame. The gutter member attached to the panel frame is as shown in FIGS. 7 and 8 depending on the shapes of the trapezoidal panel and the triangular panel.

.. are sequentially sent to the lower stage side via the meridians 342, 352. For example, as shown in FIG. 2 (b) showing a state of inflowing rainwater along one drainage system passage 320, the rainwater gathers from two directions of the parallel line portion 341 and the meridian line portion 342 at the B portion, and the C portion. Then, intruding rainwater gathers from three directions of the meridian line portion 352, the oblique intersection portion 353, and the lower latitude line portion 341. And a water collecting gutter installed at the eaves (not shown)
After that, it is drained to the outside. Therefore, the dome shaped roof 1
Even if the rainwater that falls to 00 flows in through the gap of the panel 120, the rainwater does not concentrate on the partially lowered part of the drainage system path attached to the dome-shaped roof 100, unlike the conventional case, Independent drainage channels 320, 321, 322
After that, it is discharged outdoors. As described above, since the intruding rainwater does not concentrate on one place of the dome-shaped roof 100, each joint part 200 can be downsized and the number of parts can be reduced. In addition, water leakage due to aged deterioration of the sealing material can be prevented during the repair work.

[0015]

As described above, in the present invention, the shape of the panel frame is restricted by mounting the gutter member, which is separate from the panel frame, on the panel frame and arranging it below the panel joint. It facilitates the construction of a drainage system for rainwater that enters the inside of the dome-shaped roof without receiving it. In addition, since multiple drainage channels are provided radially around the top of the dome-shaped roof and each drainage channel is independent of each other, rainwater that invades the lower part of the dome-shaped roof as in the past. Invasive rainwater can be drained smoothly along each drainage system without gathering locally. Moreover, since each drainage channel is independent, the drainage capacity of each drainage channel can be adjusted independently.
