BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a face-to-face joint structure in a polyhedral roof of a large-scale, large-space building.

[0002]

2. Description of the Related Art As a roof of a large-scale, large-scale building,
Conventionally, a simple curved single surface made of a long metal material has been proposed, but the long metal material cannot provide sufficient detail for thermal expansion displacement, wind, and deformation due to an earthquake. Since this corresponds to the internal deformation of the long material, there are some cases where the long material breaks.

On the other hand, there has been proposed a structure in which the roof surface is formed of a polyhedron and the amount of displacement and deformation of which is small can be suppressed. However, in the case of a non-continuous polyhedron, the problem of treatment of the inter-face joint occurs, but as the joint structure between the faces that abut each other at a crossing angle as described above, Japanese Utility Model Laid-Open No. 57-80520. As shown in the publication, as shown in FIG. 5, a step is provided between the surfaces of the roof material 1 and the daylighting plate 2 so that the end of the upper roofing material 1 can slip into the tip of the lower daylighting plate 2. There is something.

In the figure, 3 is a steel frame structure, 4a and 4b are arabesque drainers, an upper draining plate, 5 is a hanging lumber that serves as a mounting base for face ends, and
Indicate roof base plates, respectively. Alternatively, Japanese Patent Publication No. 59-38
As shown in the Sielta roof of Japanese Patent No. 381 gazette, as shown in FIG. 6, a space 7 having a predetermined width is secured between the roof members 1 and 1 that abut each other at the same level, and the space 7 is covered. There is a case where the umbrella-shaped decorative panel 8 is installed between the roof members 1 and 1. Although not shown in detail in the drawing, naturally, the rafter wood serving as a mounting base is interposed between the roof members 1 and 1, and the decorative panel 8 is attached to the rafter wood through a locking mechanism. ing.

On the other hand, in the case of a metal roof which constitutes a face piece, the folding engaging portions formed on the edges of the roof plates adjacent to each other are stopped by the through hangings of the upper openings arranged on the base. The flat type to be worn is, for example, Japanese Utility Model Publication No. 2-118018, Japanese Utility Model Publication No. 3-48024, and Japanese Utility Model Publication No. 4-641.

[0006]

However, in a roof having a polyhedral structure, it is necessary to make each face-piece almost flat without any protrusions so that the beauty of the metallic glossy surface can be fully utilized. Is possible. However, since the joints between the surfaces are treated with steps or raised umbrella-shaped decorative panels, as in the above, a clear division frame line is raised between the upper visual surfaces and drawn on the face body by sunlight. Cast a shadow. In this case, it is impossible to realize a beautiful crystal-cut polyhedron roof by making these into visual noise. Also, in the case of directly fixing the roof surface edge to the hanging lumber, the base is placed between the surfaces to form a perfect drain gutter that can prevent dew condensation. There is no space, and there is the disadvantage that an ideal internal drainage mechanism cannot be provided.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to form a beautiful crystal-cut surface without forming inconvenient protrusions and to form an ideal surface. It is intended to provide a face-to-face joint structure in a polyhedral roof of a large-scale, large-space building that also has an internal drainage mechanism.

[0008]

In order to achieve the above object, the face-to-face joint structure according to the present invention has a structure in which a flat type metal roof roof polyhedron has a face-to-face joint at the same level. A thin base plate is laid through a support mechanism that can secure a predetermined separation space and the surface base plate can be extended and laid to form a groove part, and then an inner gutter is assembled to the groove part, while being hung at the tip of the surface. An arabesque for fixing a silicon gasket and a silicone gasket sheet is attached to the protruding part of the child, and the side end of the silicone gasket for sealing the front end of the face and the silicone gasket sheet for covering the separated space are pressed onto the arabesque via the cover plate. That is what I did.

[0009]

The silicon gasket sheet covering the spaces between the surfaces is stretched in a hanging posture with both side ends being pressed by the flat cover plates, so that there is no projection between the surfaces. Therefore, there is nothing that causes a shadow on the surface, and the crystal cut is established here. In addition, since the separated space is provided with an inner gutter that does not cause dew condensation like the surface portion, it can perfectly cope with internal water leakage.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment will be described with reference to the drawings. In FIGS. 1 to 4, the surfaces 9 and 9 made of a flat type metal roof are abutted at the same level while ensuring a predetermined space 10. Is set. In the space 10, so-called rafters having a form of blocking the surfaces 9 and 9 are not provided,
A support mechanism 14 is installed between a pair of joists 12 and 12 that allows a base plate 11 such as a hard wood chip cement plate on the surface 9 to be extended and laid. A base plate 11 ′ having a thickness half that of the surface 9 is laid on the wood piece plate bracket 13 to form a groove 15. The cross section of the groove portion 15 is utilized to apply the weight 16 of the waterproof sheet.
A gutter 17 made of stainless steel or the like is arranged on the top of the water, and further a waterproof sheet extension 18 and a drainer 1 made of color stainless steel etc.
An inner gutter 20 is provided where 9 has been applied to ensure reliable water collection.

A suspension 21 protruding from the tip of the surface 9 for a predetermined length.
The arabesque 22 made of aluminum extruded material is assembled with the screws 23 using the (expandable suspension in the illustrated example) as a mounting base.
A silicon gasket 24 for sealing the end of the surface 9 based on the arabesque 22 and a side end of a silicon gasket sheet 25 installed for sealing between the surfaces 9 and 9 are fastened via a cover plate 26 made of an aluminum extruded material. It is stopped by the screw 27. The unsupported portion of the silicon gasket sheet 25 at the center hangs down as shown by its own weight.

Silicon gasket 24 made of roll material
Also, the silicon gasket sheet 25 can be endless, but the cover plate 26 is not possible, and as shown in FIG. In order to complete the seal of the seam 28, as shown in FIG. 4, the end portion of the cover plate 26 is cut leaving only the predetermined span upper surface plate portion 26a, and the cut portion 26b is cut as shown in FIG. A short silicon gasket 29 having the same cross section is manufactured and is inserted in the joint 28. A positive sealing effect can be expected by the pressing action of the upper surface plate portion 26a. still,
Reference numeral 30 in the drawing is a drain guide.

As is clear from the above, the outer seal of the space 10 is the long path of the silicon gasket 24 and the silicon gasket sheet 25, and is not affected by the wind at all and there is no possibility of inhalation. Further, the thermal expansion of the metal material can be absorbed by the gasket material and processed. As described above, the cover plate 26 is provided between the surfaces 9 and 9.
Since the silicon gasket sheet 25 is covered with the smooth body and the silicon gasket sheet 25 does not droop and project as described above, a substantially flat joint is formed here, and a crystal cut polyhedral roof is provided. Along with the groundwork, a perfect inner gutter will be deployed as a measure against condensation.

[0014]
