TECHNICAL FIELD OF THE INVENTION
The present invention relates to a connection structure of a roof shingle formed in a corrugated form, and more particularly to a technique for improving workability, increasing strength against a load such as snow at a connection point, and maintaining sufficient watertightness. It is.
[0002]
[Prior art]
Conventionally, a roof shingle connecting structure in which the eaves-side end 1b of the ridge-side roof shingle 1 is superimposed on the ridge-side end 1a of the metal roof shingle 1 bent into a waveform and connected by the connecting means 5 is as follows. As shown in FIG. 6 , a thin watertight seal band 6a is interposed on the eaves side of the overlap connection portion J, and a thick watertight seal band 6b is interposed on the ridge side of the overlap connection portion J. To prevent infiltration of rainwater from the eaves side. In such a configuration, a wedge-shaped space 3a is formed in the overlapping connection portion J.
[0003]
[Problems to be solved by the invention]
By the way, when the ridge side end 1a and the eaves side edge are brought into surface contact with the watertight seal bands 6a and 6b interposed in this way, the construction becomes troublesome and the wedge-shaped void 3a is formed. When a snow load is applied to the lap joint J, the eaves-side end 1b is dented and the appearance is deteriorated, and rainwater infiltrates from the contact point of the lap joint J by capillary action. However, there is a problem that water tightness is impaired.
[0004]
The present invention is intended to solve such a problem, and a connection structure for a roof slab that can enhance workability, increase strength against a load such as snow at a connection point, and maintain sufficient watertightness. The task is to provide

BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1A is a schematic cross-sectional view in the direction of the eaves at the connection point of the roof slats 1 and 1, and FIG. 3 is a schematic cross-sectional view in the direction orthogonal to the eaves direction. Since the roof panel 1 is bent into a square wave shape by roll forming, and the synthetic resin foam layer 7 is filled and foamed between the roof panel 1 and the flat metal plate 8 , the heat insulating roof panel A is formed. is there.
[0011]
As shown in FIG. 1B, the synthetic resin foam layer 7 on the lower surface of the eaves-side end 1b of the roof panel 1 of the heat-insulated roof panel A is removed, and the eaves-side end 1b of the roof panel 1 is exposed. Things. The present invention has been applied to the heat-insulating roof panel A as described above, but may be applied to a roof material without the synthetic resin foam layer 7.
When connecting the insulated roof panels A, A in the ridge eave direction, as shown in FIG. 1, the eaves-side insulated roof panel A is placed on the main building 9, and the ridge side end 1a of the roof plate 1 on the upper surface is formed. As shown in FIG. 2, a hard spacer 2 formed of, for example, a hard vinyl chloride resin into a rectangular shape is placed on the ridge a. In addition, the face door 4 is attached to the eave-side end 1b of the roof panel 1 of the insulated roof panel A on the ridge side at the mountain part a. As described above, the face door 4 may be attached to the eave-side end 1b, or may be attached to the ridge of the ridge-side end 1a. Attach to the end 1b side. A watertight seal band 6 having substantially the same shape as the face door 4 is placed on the eave side of the hard spacer 2. The watertight seal band 6 is also provided on the ridge side of the hard spacer 2, but may not be provided. The watertight seal band 6 on the eaves side is disposed above the main house 9. The watertight seal band 6 is made of EPT rubber, but may be made of another material.
[0012]
Next, the eaves-side end 1b of the ridge-side insulated roof panel A from which the synthetic resin foam layer 7 on the lower surface of the shingle 1 has been removed is a hard spacer 2 placed on the ridge-side end 1a. A bolt 5a, which is placed on the watertight seal strips 6, 6 and can be pierced as a connection means 5 such as a self-drilling screw, is connected to the eaves end 1b, the watertight seal strip 6, the ridge end 1a, the synthetic resin foam layer. 7 and is screwed into the purlin 9 to connect the insulated roof panels A, A. Instrument 4 is fixed at such a rivet or de Rirubisu from the roof plate 1 in valley b. The face door 4 may be attached to the eaves-side insulated roof panel A in advance.
[0013]
In this case, the insulated roof panel A on the ridge side is supported by the purlin 9a constructed at a comfortable position at the same roof gradient with respect to the purlin 9, that is, at a position higher by a height corresponding to the thickness of the hard spacer 2, The insulated roof panel A on the ridge side is fixed to the purlin 9a with the bolts 5a, and the construction is performed such that the upper surfaces of the insulated roof panels A, A on the eaves side and the ridge side are substantially at the same level.
[0014]
A closing plate 10 made of a metal plate is interposed on the back surface of the connection point between the heat-insulating roof panels A, A, so as to fit and make up the back surface of the connection point. In this case, an insulating seal 11 made of EPT rubber is adhered to the ridge side end surface of the synthetic resin foam layer 7 of the heat insulating roof panel A on the ridge side to protect the synthetic resin foam layer 7.
As described above, the hard spacer 2 is interposed between the eaves-side end 1b and the ridge-side end 1a of the overlap connection portion J, and withstands an excessive load such as snow on the overlap connection portion J, The appearance is not deteriorated due to the deformation, and the good appearance is maintained for a long time. Further, the hard spacer 2 is interposed between the peaks of the corrugations, and forms the drainage space 3 from the peaks of the corrugations to the valleys over the entire length of the overlapping connection portion J. Is further improved. In addition, the watertight seal strips 6, 6 are interposed on the eaves side of the hard spacer 2, and it is possible to prevent infiltration of rainwater that blows into the drainage space 3 in a strong wind.
[0015]
The hard spacer 2 is adhered to the watertight seal band 6 on the eaves side, and it is possible to avoid that the self-drilling screw is driven into the position of the watertight seal band 6 excessively and the roof plate 1 made of the steel plate at the peak a is dented. Ru der what can be.

When connecting in the eaves direction, it is sufficient to place a hard spacer between the ridge side end and the eaves side end and connect with a connection means such as a bolt, and interpose a watertight seal band as in the past On the other hand, there is an advantage that workability can be improved as compared with a work form in which a roof plate is brought into contact with the eaves side portion of the overlap connection portion. Further, a drainage space is formed in the overlapping connection portion, and there is an advantage that the drainage function is enhanced, and sufficient watertightness can be obtained in synergy with the watertight seal band. In addition, since the watertight seal band is interposed on the eaves side of the hard spacer, there is an advantage that it is possible to prevent rainwater from flowing into the drainage space in the case of strong wind. In addition, since the hard spacer placed on the peak is bonded to the watertight seal band and the connecting means is driven into the position of the watertight seal band at the peak of the roof plate , the self-drilling screw which is the connecting means is provided at the position of the watertight seal band. It is possible to prevent the roof plate made of the steel plate in the mountain portion from being dented due to excessive driving.
