Description

  The present invention relates to a fixing structure of a keraba wrap for fixing a keraba wrap attached to cover a keraba to a long folded plate roof in order to make up a keraba (end on the wife side of a roof). .

  As the fixing structure of the keraba wrap, there have been those disclosed in Patent Document 1 to Patent Document 3 so far.

Japanese Patent No. 3845648 Japanese Patent No. 2781965 JP 2010-144462 A

  By the way, a metal roof, for example, a long folded plate roof such as a double folded plate roof, repeats thermal expansion and contraction in order to receive solar radiation. For this reason, a load is applied to the fixed screw that fixes the metal roof and the keraba wrap, and there is a risk that the fixed screw is damaged due to fatigue (the screw hole is widened and the screw is pulled out).

  In Patent Document 3 described above, in order to prevent the occurrence of problems due to thermal expansion and contraction of such a metal folded plate (long folded plate roof), the fixing plate of the keraba cover (keraba wrap) support metal fitting is a metal folded plate (long A keraba cover (keraba wrap) is attached to a sliding support that is fixed to the (folded plate roof) side and slidably attached within a predetermined range along the longitudinal direction.

  On the other hand, the present invention has been intensively tested and researched to provide a “keraba wrap fixing structure” for preventing the occurrence of problems due to thermal expansion and contraction of the long folded plate roof with a structure different from that of Patent Document 3. The present invention was completed.

In order to achieve the above object, a first invention of the present invention is a fixing structure of a keraba wrap for fixing a keraba wrap to a long folded plate roof, and is attached to a long fold plate roof for fixing the keraba wrap. The base bracket and the base bracket are slidably combined in the flow direction of the long folded plate roof (longitudinal direction with a large amount of thermal expansion and contraction), and the fixing bracket with the keraba wrap attached is provided. It is characterized in that the keraba wrap is fixed without being restrained by thermal expansion and contraction.
The second invention is a fixing structure for the keraba wrap, characterized in that a part of the keraba wrap is slidably combined with the base metal in place of the fixing bracket.
The third invention is characterized in that the long folded plate roof is a double folded plate roof, the base metal fitting is attached to the upper folded plate, and the keraba packet is fixed without being restrained by the thermal expansion and contraction of the upper folded plate. It is a fixed structure of keraba wrapping.
4th invention is the folded-plate roof structure provided with the fixing structure of the keraba packet which concerns on the above-mentioned 1st invention thru | or 3rd invention.
A fifth invention is a keraba-wrap receiving bracket for fixing a keraba wrap to a long folded plate roof, and is attached to a long folded plate roof for fixing the keraba wrap, and is slidable on the base bracket. In addition to the combination, a fixing metal fitting for attaching the keraba wrap is provided, and the keraba wrap is fixed without being restrained by the thermal expansion and contraction of the long folded plate roof.

According to the present invention described above, the following effects are obtained.
(1) The present invention does not fix the keraba wrap directly to the long folded plate roof (in the case of double folded plate roof), but a receiving bracket (base bracket and fixing bracket or base bracket only) By interposing, the thermal expansion and contraction of the long folded plate roof (in the case of a double folded plate roof) is not constrained.
(2) For this reason, it is possible to reduce a load on a fixing member (for example, a fixing screw) that fixes the keraba packet, and to prevent the breakage (for example, the removal of the fixing screw).
(3) Since the keraba wrap is not directly fixed to the long folded plate roof (upper folded plate in the case of double folded plate roof), the long folded plate roof (double folded plate roof in the upper folded plate) Can reduce the risk of rain leakage.
(4) Furthermore, by interposing a receiving metal fitting (base metal fitting and fixing metal fitting), this becomes a supporting member, and the sinking of the keraba wrap due to snow accumulation can be prevented.

Explanatory drawing (3) which shows 1st Embodiment of this invention. Explanatory drawing (4) which shows 1st Embodiment of this invention. Explanatory drawing which shows 2nd Embodiment of this invention.

  Embodiments of the present invention will be described with reference to the drawings. In addition, here demonstrates as an object the double folded plate roof which uses the slide heat insulation metal fitting as a long folded plate roof. “Slide heat insulating metal fittings” are used for joining upper and lower folded plates in roofs where there is concern about thermal expansion and contraction of double folded plates. Therefore, harmful fatigue damage of the heat insulating metal fitting can be prevented.

1 to 4 are explanatory views showing a first embodiment of the present invention.
As shown in FIG. 1, the fixing structure of the keraba wrap is as follows. First, the base metal fitting (A) is attached to the upper folded plate 50 of the double folded plate roof for fixing the keraba wrap (not shown) by screw fixing or the like. The base metal fitting (A) is combined with the fixing metal fitting (B) so as to be slidable in the flow direction of the upper folded plate 50. The slidable combination of the base metal fitting (A) and the fixing metal fitting (B) shown in the figure is a substantially V-shaped rail groove ( The inner inclined surface (A2) of A1) and the inclined piece (B2) of the substantially U-shaped end (B1) of the fixing bracket (B) extending in the same flow direction are brought into contact with each other and engaged.

  However, the slidable combination of the base metal fitting (A) and the fixing metal fitting (B) is not limited to the illustrated one. In the drawing, for convenience of explanation, the base metal fitting (A) is attached to the upper folded plate 50 and then the base metal fitting (A) and the fixing metal fitting (B) are combined. It is more efficient to attach the base metal fitting (A) to the upper folded plate 50 after combining the fixing metal fitting (B).

  Next, as shown in FIG. 2, the keraba wrap 40 is attached to the fixing metal fitting (B) slidably combined with the base metal fitting (A) by screw fixing or the like. This completes the fixing structure of the keraba wrap. FIG. 3 is a cross-sectional view of the completed keraba wrap fixing structure seen from the underwater side. In addition, the code | symbol 60 is a downward folding plate, the code | symbol 70 is a slide heat insulation metal fitting, the code | symbol 80 is an L metal fitting, and the code | symbol 90 is a wife tight frame.

  As shown in FIG. 4, in the case of the fixing structure of the above-described keraba wrapping, the base metal fitting (A) simply slides with respect to the fixing metal fitting (B) following the upper folded plate 50 that is thermally expanded and contracted. The keraba packet 40 that is directly fixed only to the fixing bracket (B) does not restrain the thermal expansion and contraction of the upper folded plate 50. Therefore, no load is applied to the fixing member (fixing screw or the like) used to fix the keraba packet 40, and damage to the fixing member due to fatigue can be prevented.

FIG. 5 is an explanatory view showing a second embodiment of the present invention.
As shown in FIG. 5, the fixing structure of the keraba wrap is such that a plate-like base metal fitting (A ′) is attached to the upper folded plate 50 of the double folded plate roof for fixing the keraba wrap 40 by screw fixing or the like. Instead of this, a part (end part) of the keraba wrap 40 is bent to form a locking part 41, and this locking part 41 is slidably combined (hung) to the base metal fitting (A '). Since others are the same as those in the first embodiment, description thereof is omitted.

  The present invention can be widely used as a structure for fixing a “keraba wrap” to a metal roof that repeatedly undergoes thermal expansion and contraction.
