Description

[Detailed description of the invention] [Industrial application field] The invention relates to a connection structure of a roof panel, and relates to an improvement of a roofing structure that is roofed using a roof panel.

[Prior art] Conventionally, as a prefabricated construction method, a roofing sheet and a roof tile are laid on a base plate having a unit size in advance, and a roof panel having the unit size is arranged and fixed on the roof at a stretch. A method of finishing a roof may be adopted (for example, Japanese Utility Model Publication No. 25-1041).

When the roof is to be roofed by such a construction method, it is necessary to cover a gap generated in a continuous portion of the roof panel, and as shown in FIG. The roofing material A 'to be laid on the top is alternately extended on the unevenness, and the insertion plate A "is inserted every other stage to perform the raining, and the roofing material A' as shown in FIG.
And a flat substrate B, a substrate C is interposed therebetween, and roof materials A ', A' are applied from both sides thereof.
The drainer D is fitted to the substrate C projecting upward from between, and the roof members A 'and A' are sandwiched between the substrate C and the drainer D and a gap E is sealed. .

[Problems of the prior art] However, in the case of the above-mentioned method, when the former roof material extension roof panel is used,
There is a problem that the waterproof layer of the roof base cannot be securely joined because the roofing material A 'extends every other sheet at the joint.

In addition, since the upper part of the insertion plate A "for waterproofing the joint is inserted under the extended roof material A ', the insertion work becomes difficult, and the insertion part cannot be nailed and is securely fixed. However, there is a problem in that if the nail is forcibly fixed, the exposed portion must be nailed, which is inconvenient in terms of waterproofing.

On the other hand, in the case of the latter means using the drainer D, the drainer D is formed of metal or aluminum or the like,
Since the roofing material A 'is a different kind of material and is exposed on the outer surface of the roof after the roofing, there is a disadvantage that the continuous appearance of the roofing material by the roofing material A' is impaired.

In addition, water leakage is likely to occur due to incomplete connection between the drainer D and the substrate C, and even when the drainer D and the substrate C are formed as an integral molded product, adjacent drainage molded products in the longitudinal direction of the gap are formed. However, there is a problem that water leaks at the connection part because the connection is difficult.

[Problems to be solved by the invention]

SUMMARY OF THE INVENTION In view of the above problems, the present invention provides a roof panel connection structure that can maintain a continuous appearance of a roofing material and can appropriately maintain waterproofness of a butt gap portion of a roof panel. It was made for the purpose of.

[Technology to solve the problem]

That is, the connection structure of the roof panel of the present invention is that the roofing material is staggered on the planar substrate via the waterproof sheet, and the roof is fixed in advance by leaving the exposed portion on the side end surface of the planar substrate. A roof panel connecting structure, wherein a waterproof tape is adhered between planar substrates of the roof panel whose end faces are abutted to each other. Joint plates having two types of widths, which can be fitted into the gap, are arranged alternately while partially overlapping in the roofing direction between the roof materials facing each other, and the joint plates have upper end portions. Is nailed to the planar substrate, and the nailed portion is covered with a joint plate stacked on top.

〔Example〕

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

1 is a partially cutaway plan view of an embodiment of the present invention, FIG. 2 is a sectional view taken along the line II-II of FIG. 1, and FIGS. 3 and 4 are plan views of a joint plate used in the embodiment of the present invention. FIG.

The connection structure of the roof panel of the present invention is such that the roofing materials 2... 2 are staggered on the planar substrate 1A via a waterproof sheet 1B such as a roofing sheet, and the exposed portions 1C are provided at the side ends of the planar substrate 1A. In joining the roof panel 1 which has been roofed and fixed in advance while leaving 1 C, a waterproof tape 3 is attached between the planar substrates 1A of the roof panel 1 whose end faces abut each other. in wood 2 the same quality, and between the roofing material 2 and 2 wide and narrow two gaps S _1, also wide and narrow two joint plate 4A has a width capable of fitting to the S _2, 4B are opposed to each other between the roofing material 2 They are arranged alternately in the roofing direction.

In the above, the roofing material 2 laid on the roof panel 1 ...
As shown in the figure, the roofing condition of 2 is staggered by 1/3 width as shown in the figure, and in addition to the above, 1/2 or other real number It is laid in a state where it was shifted one by one.

Accordingly, the facing gaps S ₁ and S ₂ between the roofing materials 2... 2 of the roof panels 1 and 1 which are abutted with each other have a wide and narrow interval of 1: 2 as shown in FIG.

In addition, the width of the gap S ₁ between the roofing materials, S ₂ is arbitrary as described above, but in order to increase the waterproofness of the overlapping portion of the joint plates 4A and 4B that are laid on the gaps S ₁ and S ₂ , The width L of the joint plate 4A having _two wide gaps S ₁ and S ₂ is equal to or greater than the sum of the width 1 of the narrow joint plate 4B and its working width d (L ≧ 1 +
d) is desirable.

Further, although the case where the rectangular roof material 2 is used is shown as the above embodiment, the same can be achieved by using another shape roof material as shown in FIG.

[Action]

According to the above structure, since the exposed portion is formed at the side end of the planar substrate 1A of the roof panel 1, the waterproof tape 3 can be easily attached to this portion, and the metal or aluminum as in the conventional case can be used. Even without using a drainer as described above, the waterproofing treatment is performed by the waterproof tape 3 and the joint plates 4A and 4B similar to the roof material 2 laid on the waterproof tape 3.

When the joint plates 4A and 4B are to be roofed, the lower joint plate 4A is placed over the two flat substrates 1A and 1A in the gap between the joints and then fixed with nails, and the upper joint plate 4B is covered by covering the nailed portions. The joint plates 4A and 4B are fixed over the two flat substrates 1A and 1A, and the fastening strength is improved, since they are overlapped, placed again on the two flat substrates 1A and 1A, and then fixed to the nails. In addition, the overlap with the nail hole can be sufficiently removed, and the waterproof property can be secured.

〔effect〕

As described above, in the connection structure of the roof panel of the present invention, there is no exposure of a different kind of member to the outer surface of the roof, and the continuity of the roof material is maintained, so that the appearance and appearance are improved. In addition, the joint gap of the roof panel is double-covered with waterproof tape and a joint plate, so that waterproofness is suitably maintained. Further, since the joint plates are fixed to both base plates with nails, respectively, they have excellent fastening strength. Has a practical effect.
