BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention generally relates to a supporting structure for a roofing board of a thatched roof in which metal roofing boards are used in a horizontal orientation, and the roofing board is fixed to the roofing board. It relates to the fixed structure on the main roof and the water storage structure of the roof thus supported.

[0002]

2. Description of the Related Art In a building with a normal floating roof, a purlin is erected on a shed structure, a slack is arranged, a field board is laid on the entire roof surface, and a roof tile or its equivalent is laid on the upper surface. .. In roofs such as roofing made of metal as roofing material, there are many roof structures that have a metal structure above the purlin, and the structure above the purlin takes advantage of the long metal plate to create a roof tile roof. Or using a metal rafter to make that sideways. And in any roof structure, the water storage is important, especially the structure of the slack supporting the roofing material and the watertight structure between the slacks.

Now, referring to FIG. 5, an example of a side-roofing structure of a metal plate roof will be described. In a pitched roof 1, a metal barrel (hereinafter simply referred to as a barrel) 3 is fixed directly on a steel frame purlin 2, A base plate 4 made of a wood wool cement plate formed to have the same thickness as the height of the taro 3 is dropped, a waterproof sheet 5 is laid on the upper surface thereof, and a roof plate 6 is roofed. In the roof structure as described above, after the base plate 4 is laid between the slacks 3, the roof plate 6 is provided in parallel with the eaves.
Thatched. At the upper edge of the roof plate 6, the engaging side 61 is folded back on the upper surface side to form a water drain, and at the lower edge, the engaging side 62 is bent upward at the lower surface side. 6 is fixed in order from the eaves side, the suspension 7 having the hook 71 formed on the engaging side 61 is fixed from above, and the fixing portion 72 projecting upward is fixed to the upper surface of the slack 3 to form the horizontal plate. The roof plate 6 is fixed. Next, such construction of the roof plate 6 is continued in the lateral direction, and the engagement sides 62 of the upper roof plate 6 are overlapped from above, and the engagement of the upper and lower roof plates 6, 6 is measured and fixed. Then, the same step as above is repeated for the roofing. In the figure, reference numeral 8 is a joint portion of the roof plate 6, and 9 is a front cover of the eaves.

In the above roof structure, as shown in FIG. 6, the rafter 3 is generally called a hat-shaped rafter as shown in the drawing, but the cross-sectional shape is not limited to this. Also, octagonal and rectangular tubular sardines are often used. Tartar 3 is a side flange 3 on the upper surface of purlin 2.
The fixed part 72 of the above-mentioned hangings 7 which mounts a and is fixed using the self tap screw 3b and supports the roof plate 6.
Is fixed to the upper surface 3c of the slack 3 using tap screws.

[0005]

One of the difficulties in the conventional roof structure of horizontal board and roof is that the roof board 6 connects the thin metal plates by the engagement of the upper and lower bent edges. When the bending engagement portion is deformed by an external force at the time or after the construction and the so-called seam joint is loosened, water leaks from this defective portion of the primary waterproofing. Further, as another difficulty, in the waterproof sheet 5 as the secondary waterproof, staples are used when the waterproof sheet 5 is stretched and fixed on the ground board 4 of the wood wool cement plate, so that tension such as expansion and contraction due to temperature change is applied. It is easily damaged and the fixing holes tend to expand. Further, when the roof plate 6 is fixed to the slack using the suspenders 7 at the time when the base plate 4 is filled between the slacks 3, a screw or the like of the fixing means makes a hole in the waterproof sheet. Or, by performing the attachment structure of this suspension between the cut and raised parts formed on the slap side and the notch of the suspension,
A leak passage is formed in the waterproof sheet. Therefore, in the support structure of the roof plate 6 characterized by a relatively small structure, as in the structure of the joint portion 8 at the end of the roof plate 6, as a backup means for each part where there is a risk of water leakage, A third watertight structure is required.

SUMMARY OF THE INVENTION In view of the above problems, the present invention attempts to improve the support structure on the roof of a roof panel, and therefore, of a side-roof roof with a reasonably improved waterproofness. It was devised for the purpose of providing a support structure, and an upward groove-shaped fixing member is attached to the allocation support position of the slack on the upper surface of the purlin with the groove facing the direction of the slack.
Locking ribs are formed opposite to each other on the upper ends of both side walls of the fixing member, and engaging holes for fitting the locking ribs are provided on the side surfaces of the slack, and the slack is provided between the upper side of the fixing member and the side wall. It is characterized by fitting and supporting, and with this structure, a discard plate is also provided on the lower surface of the field plate and waterproof sheet filled in the middle of the rafter, and this discard plate is fixed. Avoiding the members, the rising part along the side wall of one slack, the valley part located on the upper surface of the purlin, the rising part along the side wall of the adjacent slack, and the cover from the upper end to the upper part of the slack. It is characterized by a surface and a falling part that is bent from the outer edge and covers the rising part of the adjacent discarding plate, and the basic waterproofing of the roofing plate is primary and the waterproof sheet is secondary. In addition, by forming a third waterproof layer with a discard plate Te, is obtained by completing the support structure of the roofing plate at each stage.

Therefore, according to the present invention, in a roof in which a metal roof plate is used in a horizontal direction and the roof plate is laid horizontally, a fixing member is attached to the steel frame roof without directly fixing the taro.
Since the roof board is supported by fitting a hollow slack through this fixing member, there is no risk of water leakage at many fixing points of the roof board, and furthermore, the purpose of fixing the roof board to the slack Even if there is water leakage from the hole or notch formed in, the hollow sardine forms a drainage channel and is guided to the eaves.
Also, even if water leaks to the roof surface in the middle of the slack, the waste board laid in the middle of the slack also forms the third waterproof, so it is likewise guided to the eaves and indoors. Therefore, even if the conventional roof plate support means is adopted in this type of roof structure, there is no risk of water leakage through the roof plate.
