  An embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1, the roof tile roof 100 according to the present embodiment is formed with a folded portion 112 inclined at an acute angle inward and downward at the upper ends of a pair of upright portions 111 erected upward. A metal roof plate 110 that forms a plurality of tiles (parts) 113 arranged at predetermined intervals on the upper surface of the roof RF, and a holding portion 121 that is positioned in a gap between a pair of adjacent metal roof plates 110 and a pair of A pair of engaging portions 122 that are individually engaged with the folded portions 112 are formed, and the support member 120 arranged in the gap between the plurality of metal roof plates 110 and the folded pair of adjacent metal roof plates 110 are folded. A pair of acute-angled bent portions 131 engaged with the portion 112 via the engaging portion 122 are individually formed on both sides of the upper surface portion 132, and the gap between the support member 120 and the upper member 130 is vertically Position compressed in direction It has a packing member 140, the that.

  Further, in the tiled bar thatched roof 100 of the present embodiment, a flat backup member 150 is inserted in the gap between the upper surface of the packing member 140 and the lower surface of the upper surface portion 132 of the upper member 130.

  In addition, a sheet mounting member 160 to which a waterproof sheet 170 applied to the roof RF of the building is attached is disposed on the upper surface of the upper surface portion 132 of the upper member 130 via the cross sheet 180. The cross sheet 180 protects the waterproof sheet 170 and is formed of polyethylene resin or polyester.

  The sheet mounting member 160 is fixed to the upper member 130 and the backup member 150 with a tapping screw 161 via a cross sheet 180, and the tapping screw 161 is connected to the sheet mounting member 160, the cross sheet 180, the upper member 130, and the backup member 150. It penetrates through the member 150.

  A heat insulating material 141 is disposed between the standing portions 111 of the metal roof plate 110. A cross sheet 180 and a waterproof sheet 170 are laid on the entire structure as described above, and the waterproof sheet 170 is a surface on which a resin of a sheet mounting member 160 made of a disk-shaped resin-coated steel plate is coated. It is fixed by heat fusion.

  More specifically, the metal roof boards 110 arranged at predetermined intervals are formed in an elongated shape in the front-rear direction passing through the drawing, and the support member 120 is arranged in the longitudinal direction. The upper member 130, the packing member 140, and the sheet mounting member 160 are arranged at the positions of the support members 120 arranged in this way. As shown in FIG. 2, a portion composed of the adjacent standing portions 111 of the metal roof plate 110 arranged at a predetermined interval in this way is referred to as a tile rod (portion) 113.

  As a result, a plurality of metal roof plates 110 that are elongated in the front-rear direction are arranged in the left-right direction on the surface of the roof RF, and the support member 120, the upper member 130, the packing member 140, and the sheet mounting member 160 are spaced at predetermined intervals in the left-right direction. Will be arranged.

  In the structure as described above, in the tile rod-fired roof 100 of the present embodiment, the sharp bent portions 131 on both sides of the upper member 130 are formed on the metal roof plate 110 by the restoring force of the packing member 140 compressed in the vertical direction. The folded portion 112 is firmly engaged.

  For this reason, as shown in FIG. 8, even if the waterproof sheet 170 is released due to a strong wind or the like and the upper member 130 is pulled upward together with the sheet mounting member 160, the upper member 130 does not fall off from the tile rod (part) 113.

Since the sheet mounting member 160 and the backup member 150 are considered to be integrated (in a state where the plate thickness is increased), the deformation holding force against the pulling stress is improved, and the upper member 130 is the roof bar (part) 113. Is prevented from falling off.

  In addition, the sheet mounting member 160 is fixed to the cross sheet 180, the upper member 130, and the backup member 150 with a tapping screw 161, and the tapping screw 161 passes through the sheet mounting member 160, the upper member 130, and the backup member 150. ing.

  Therefore, the sheet mounting member 160 to which the waterproof sheet 170 is fixed is securely fixed to the upper member 130 and the backup member 150 with the tapping screw 161. In addition, since the packing member 140 in a compressed state presses the backup member 150 from below, the upper member 130 and the backup member 150 are more closely integrated with each other by fixing the tapping screw 161.

  Therefore, the tip of the penetrating tapping screw 161 is positioned inside the packing member 140, and the tapping screw 161 penetrating the upper member 130 and the backup member 150 does not penetrate the holding portion 121. There is no cause.

  Here, the roof construction method for waterproofing the roof tile roof 100 according to the present embodiment will be described in order below. First, as shown in FIG. 2, a plurality of metal roof boards 110 in which a folded portion 112 inclined at an acute angle is formed on the upper side of a pair of upright portions 111 erected upward are formed on the building. Arranged at predetermined intervals on the upper surface of the roof RF, tile bars (parts) 113 arranged at predetermined intervals are formed.

  Next, as shown in FIG. 3, a holding portion 121 located in a gap between a pair of adjacent metal roof plates 110 and a pair of engaging portions 122 that individually engage with the pair of folded portions 112 are formed. The plurality of support members 120 are arranged in the gaps between the plurality of metal roof plates 110.

  At this time, as shown in the figure, the linear engagement portion 122 may be bent after the support member 120 is disposed on the metal roof plate 110, and the engagement portion 122 of the support member 120 bent from the beginning is also possible. May be engaged with the folded portion 112 of the metal roof plate 110.

As shown in the figure, the packing member 140 is formed thicker in the vertical direction than the depth of the opening of the support member 120. As will be described in detail later, the packing member 140 is made of a flexible urethane foam or the like and has a predetermined elasticity.

  In this state, as shown in FIG. 5, a metal flat backup member 150 is placed on the upper surface of the packing member 140, and the upper member 130 is turned from above to the folded portion of the metal roof plate 110 on both sides. 112 is engaged.

  At this time, the metal flat backup member 150 is not placed in advance on the upper surface of the packing member 140, and the folded portions 112 of the metal roof plate 110 on both sides of the metal flat backup member 150. After the engagement, the backup member 150 may be inserted into the gap between the packing member 140 and the upper member 130.

  More specifically, since the folded portion 112 is engaged with the engaging portion 122 of the support member 120 as described above, the bent portion 131 of the upper member 130 is formed between the pair of adjacent metal roof plates 110. The folded portion 112 is engaged through the engaging portion 122.

  Since the packing member 140 is formed to be thicker in the vertical direction than the opening depth of the support member 120 as described above, the upper member 130 is attached to the metal roof plate 110 with the packing member 140 compressed downward. Is done.

  Next, as shown in FIG. 6, the heat insulating material 141 is arrange | positioned inside the metal roof board 110 with which the upper member 130 was mounted | worn as mentioned above. The heat insulating material 141 is made of, for example, styrene foam, polyvinyl chloride, soft urethane foam, and the like, and is fixed to the metal roof plate 110 by adhesion or the like.

  And as shown in FIG. 7, the cross sheet 180 is laid in the upper surface whole area of the upper surface part 132 and the heat insulating material 141 of the upper member 130 with which it mounted | worn for every pair of metal roof boards 110 as mentioned above.

  The position of the upper member 130 is confirmed from the upper surface by appearance and palpation, and the sheet mounting member 160 is disposed on the upper member 130, and the sheet mounting member 160 is tapped on the cross sheet 180, the upper member 130, and the backup member 150. Secure with screws 161.

  Here, the structure in which the sheet mounting member 160 is fixed to the upper surface of the cross sheet 180 is illustrated. However, the cross sheet 180 may be cut out or torn at the position of the sheet mounting member 160 (not shown).

  When the sheet mounting member 160 is fixed to all of the plurality of upper members 130 as described above, as shown in FIG. 1, a waterproof sheet 170 is laid on the whole and fixed to the sheet mounting member 160 by adhesion or welding.

  The tiled bar thatched roof 100 manufactured as described above, even if the waterproof sheet is released by a strong wind or the like and the upper member 130 is pulled upward together with the sheet mounting member 160 as described above, ) Do not fall off from 113.

  Here, the experimental result of the prototype by the present inventor is exemplified below. First, in the tile roof, in the conventional method, the sheet mounting member 160 is nail-fixed to a steel frame that penetrates the base and has a fixed strength. This method, however, prevents water leakage and damage to the attic material (mainly wood wool cement board, etc.). Concerned. When the upper member 130 is hooked on the tile rod (part) 113 of the metal roof plate 110 and the fixing strength is maintained by the deformation resistance strength of the upper member 130, this concern is improved.

  However, if the upper member 130 is easily processed (thinned), the fixing strength to the sheet mounting member 160 is weak, and if the upper member 130 is thickened, there are problems such as high cost and difficulty in processing, and fixing to the roof bar (part) 113 is troublesome. The suitable upper member 130 was examined.

Test type / fixing (fitting) of the upper member 130 to the base of the metal roof plate 110 → (screw) fixing of the sheet mounting member 160 to the upper member 130 → Verification of the pulling strength of the sheet mounting member 160. “Excel-FM” is a product name.

Pull-out strength Details (Studies were stopped for n = 2 and not exceeding 1.5 kN on average).

From the above results, the fixing means is determined to be Excel FM, and the backup member 150 is attached to the upper surface of the upper member 130.

Further, considering the structure, the backup member 150 is inserted into the lower surface of the upper member 130.

[Conclusion]
When fixing using the upper member 130 alone, the plate thickness should be at least 1.0 mm. → Even if the plate thickness is less than 1.0 mm, it can be handled by increasing the number of fixings according to strength. However, it is inefficient and expensive.

  As a method for increasing the thickness of the fixing portion of the sheet mounting member 160 of the upper member 130, a method of mounting and reinforcing the upper plate made of a steel plate on the upper member 130, the top surface and the upper plate of the upper member 130 are separately provided. Deformation could not be expected to increase the thickness.

  Next, when the back plate is put on the back surface of the upper member 130 and pushed into the gap with the packing member 140, the top surface of the upper member 130 and the back plate are deformed together, and the effect of increasing the thickness is exhibited. did.

  When the back plate is used together with the upper member 130, the upper member 130 having a plate thickness of 0.5 mm (back plate 1.0 mm) or the upper member 130 having a plate thickness of 0.8 mm (back plate 0.8 mm or more) is about 1.9 kN. The pull-out strength can be secured, but it is easy to select both 0.8 mm from the manufacturing efficiency of the material.

The packing member 140 is preferably provided with an adhesive layer on one surface of a relatively hard soft urethane foam having a density of about 30 (kg / m ³ ) or more, and cut into the inner width of the tile rod (part) 113. Align (1-2 m length).

However, in order to avoid thermal expansion, it is preferable to arrange them with a gap of about 10 mm. If it is a flexible urethane foam having a density of about 30 (kg / m ³ ), the manufacturer's designation is unnecessary.

  The present invention is not limited to the present embodiment, and various modifications are allowed without departing from the scope of the present invention. That is, in the above-described embodiment, the structure of each part has been specifically described. However, the structure and the like can be variously changed within a range that satisfies the present invention.
