Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a roof structure in which metal tiles are fixed using hangers.

(b) Prior art In recent years, metal roof tiles have come into widespread use.
As a result, more and more roof structures are using hangers.

An example of this is Japanese Utility Model Application No. 50-27617, in which a special nail 4 having a special nail arm portion 41 and a special nail holding hardware portion 42 is used as a hanger.

Another example is Utility Model Publication No. 57-139520. In this configuration, first, a bent edge 4 and an edge 5' are provided on the tile-like metal roofing material 3, and on the back side of the bent edge 4, a fixed part of the locking piece 6 consisting of a fixed part 6' and a fitting part 6'' is formed. 6' is fixed by spot welding. Then, the fixed part 7' of the locking part 7 is fixed to the central upright part of the roofing material fixing body 2 to form the locking gap 7. Then, the tile-like metal roof is fixed. The edge portion 5' of the member 3 and the fitting portion 6'' of the locking piece 6 are inserted into the locking gap 7 to be fixed.

Other common methods include nailing the tiles from the front of the step, and using a structure in which metal tiles located above and below interlock with each other.

(c) Problems to be solved by the invention In Utility Model Application No. 50-27617, since the head of the special nail 4 and the head of the special nail retainer hardware part 42 protrude above the special nail arm part 41, When pressure is applied to the shingles, the surface of the shingles becomes uneven, resulting in a poor appearance.

In addition, in Utility Model Application No. 57-139520, the fixed part 6' is fixed to the back side of the bent edge 4 of the tile-like metal roofing material 3 by spot welding, but since spot welding is welding with an electrode, the melting point of the copper plate etc. It is somewhat difficult to weld sheet metals with low heat resistance, and painted sheet metals have the problem that spot welding is impossible because the painted material acts as an insulator.

Furthermore, the method of nailing from the front of the stepped part exposes the nails to be fastened, causing rust to form in the nails and nail holes, impairing the durability of the metal tiles, and causing the metal tiles located above and below to overlap each other. Those with an interlocking structure require severe bending or wringing to make the interlocking parts firm, and there is a problem in that the roofing material is easily damaged during this process. The scratches may end up on the surface of the roofing material, making it impossible to handle it as a product.

The present invention solves these problems and can be applied to any roofing material, avoids damaging the surface of the roof shingles during the processing stage, and prevents pressure such as treading during construction. The purpose of this invention is to provide a roof structure with extremely few irregularities that occur on the roof plate surface.

(d) Means for solving the problem The metal tile body is oblong in shape, and has a downward wall bent downward under the water and a seam section bent inward at approximately right angles, and above the water is a downward wall bent downward. There is an upward wall that is bent at a right angle, and a horizontal wall that is bent outward at a substantially right angle. A recess is provided in the side wall to accommodate the thickness of the hanger, and the hanger is attached here.

The hanger is in the shape of a horizontal L-shape with an upper surface and a lower surface, and has protrusions on the left and right sides.

The upper surface of the hanger is placed over the recessed part of the metal tile main body, and it is fixed to the crosspiece with a fastener, and the next roof plate's seam is placed over the hanger and fitted.

(e) Example First, the structure of the roof will be briefly explained based on FIGS. 7 to 10.

The C-beams 17 are installed in a direction perpendicular to the ridge, and the intervals between them are about 500 mm to 1000 mm.
A base material 20 is arranged on top of the C-shaped steel 17, and waterproof paper 21 is stretched. On top of this, as shown in FIG. 10, crosspieces 15 are arranged parallel to the ridge at intervals of the metal tile tile length 23, and fastened with fasteners 22 shown in FIG. 9. The metal tile main body 1 is roofed while inserting backup material 19 between the crosspieces 15 and 15.

The metal tile main body 1 according to the embodiment of the present invention has a horizontally elongated shape as shown in FIG. 1, and has an appropriate number of consecutive peaks 8 and valleys 7 (see FIG. 4). moreover,
As shown in Figures 2 and 3, a mountain downward wall 2' is provided below the water of the mountain part 8, and a valley downward wall 2 is provided below the water of the valley part 7, respectively. There is a bevel 3 approximately perpendicular to the direction. Further, a mountain uphill wall 4' is provided above the water in the mountain 8, and a valley uphill wall 4 is provided above the water in the valley 7, and each side wall 5 is provided at a substantially right angle outward. This horizontal wall 5 is provided with a recessed portion having a depth sufficient to accommodate the thickness of the suspender 10, and this is used as a suspender stop portion 6.

Next, an embodiment of the hanger 10 will be described with reference to FIGS. 5 and 6.

The hanger 10 has an upper surface and a descending surface 14, and the descending surface 14 presses the seam part 3 of the metal tile body placed over it.

The center part of the upper surface of the hanger 10 forms a fastening part 11,
The left and right ends of the upper surface are provided with protrusions 13. The level difference between the fastening part 11 and the protrusion 13 is set to a height that allows the head of the fastening tool 16 to fit comfortably therein (see FIG. 5). This fastening part 11 has a hole 12 for a fastening tool.

The upper surface of this hanger 10 is overlapped with the hanger stopper part 6 of the metal tile main body 1, and fixed to the crosspiece 15 with a fastener 16. The joint part 3 of the next metal tile main body is placed over the hanger 10 and fitted. Repeat this process to cover the roof.

(F) Effects The roof structure having a hanger according to the present invention has a recess into which the hanger can fit snugly into a horizontal wall provided above the water, and the hanger is attached to this recess. For this reason, when pressure such as tread pressure is applied during construction,
This eliminates the problem of unevenness on the surface of the roof board due to the thickness of the hangers, and the beauty of the exterior can be maintained.

In addition, there is a seam under the water of the metal tile body, and it is fitted by covering the hanger on the lower level that has been fixed first, but at this time, because the hanger has protrusions on the left and right, The ridges come into contact with the ridges, allowing for good drainage and preventing rainwater from accumulating, which can cause corrosion.

The hangers are fastened to the crosspieces using fasteners, and the bulges of the upper roof panels are placed over the hangers, so the nails to be fastened are exposed and rust forms from the nails and nail holes, causing metal tiles to deteriorate. This eliminates the problem of damaging the durability of the product.

Furthermore, the hanger has the advantage of being strengthened by the ridges on the left and right sides. Even if the head of the fastener is thick, the head will fit between the ridges of the hanger, so it will not cause unevenness on the surface of the roof board.

Since the roof structure according to the present invention has no welded parts, there is no problem in using copper plates or painted sheet metal, and it can be applied to any roofing material.

Furthermore, since there are no complicated bends, there is no damage to the surface of the roof panels during processing.
