The present invention relates to a structure for fixing and connecting a structure on both sides of a trough, a trough cap member attached to the upper surface of a trough and a roof plate.

[0002]

[Prior Art]

 In a building with a normal floating roof, a main building is erected on the shed, slabs are laid, a roof plate is laid on the entire roof surface, and roof tiles or their equivalents are roofed on the top surface. In roofs such as roofing made of metal as the roof panel, many roof structures have a metal structure above the purlin, and the structure above the purlin takes advantage of the long metal plate to create a vertical structure. It is done with a roof tile or a roof with a metal roof. And in any roof structure, it is important to keep the rain away, and especially the water-tight structure at the joints of the members that make up the roof.

Now, referring to FIGS. 6 and 7, a description will be given of an example of a conventional roofing structure for a valley portion of a metal plate roof. FIG. 6 shows a plane perpendicular to the valley portion of a building having a cross roof surface. FIG. 7 is a cross-sectional view and FIG. 7 is a plan view of a corner portion of a roof including a valley portion. In a pitched roof 1, a metal tarp (hereinafter simply referred to as a tarp) 3 is directly fixed on a steel frame purlin 2, and a wood wool cement is formed between the tarps 3 to have the same thickness as the height of the tarp 3. The base plate 4 of the board is dropped, the waterproof sheet 5 is laid on the upper surface thereof, and the roof board 6 is roofed. In the structure of the roof as described above, in the portion forming the valley 7, the corners 3A are arranged on the corner purlins 2A connecting the ends of the purlins 2 on both sides, and between the corners 3A on both sides. A discarding plate 4A made of a steel plate having a substantially M-shaped cross section is stretched over the valley, and a shallow V-shaped valley 7 is formed on the discarding plate 4A, and especially a waterproof sheet 5 for asphalt roofing is used. Are laid in double, and a plurality of folded folds 81 are formed on both sides of the valley 7, and the trough 8 having a valley 82 in the center is fixed. As shown in FIG. 7, the trough 8 is formed to have a width W having an overlapping portion that is sufficiently obliquely above the end portion 61 of the roof plate 6 that is closer to the valley. Is formed by folding back, and the slanted end portion 61 along the valley portion 7 of the roof plate 6 is fixed so as to be grabbed in the shape of a seam and fixed. Reference numeral 9 in the figure denotes a lateral connecting portion of the roof panel 6 in the general portion of the roof 1.

[0004]

[Problems to be solved by the device]

 One of the difficulties in the conventional structure for accommodating the valley portion 7 is that the trough 8 is the final member in terms of the waterproof function of the roof, and the metal plate having the watertight structure is exposed on the roof surface. Therefore, the concave portion lacking the roof plate is formed as a "valley" on the roof surface, which is not only unfavorable in terms of design, but also tends to be a weak point of durability. Further, as another difficulty, when the roof panels on both sides face each other on the above-mentioned trough, it is not allowed to directly fix the ends to the trough 8, and the folds 81 formed by folding the roof panel 6 are not allowed. A problem peculiar to the valley part when gripping and engaging in the shape of a seam is that the three-dimensional on-site size adjustment on the slope is troublesome, and in the means for fixing and fixing the roof plate 6, the plate material Depending on the thickness of the rail, sufficient grip may not be secured.

Therefore, it is conceivable to make a connection in the construction direction of the roof plate while bending it at a valley portion at a straight angle, such as a horizontal connecting part 9 (FIG. 7) of the roofing plate. A valley cap member can be used according to the cap member used for the connection part, but when inserting the valley cap member between the ends of the roof plate on both sides of the valley part, such as during construction or in strong wind. There is a tendency to slip along the valley, and downward members may stir the wind and cause a disaster. In the mounting structure of the trough cap member or trough part added to the trough as described above, it is necessary that all the fixing means of the member above the slap face use the base plate as the base and penetrate the waterproof sheet. In addition, since the members are always stacked on the lower member as a normal way to protect the roof from rain, in a roof structure consisting of light members, the wind blown along the roof surface is the most disadvantageous. Inevitably, the conditions required for the connecting member of the roof plate on the upper surface of the trough are extremely severe.

[0006]

[Means for Solving the Problems]

 In view of the above problems, the present invention has been made with the object of providing a roof structure that is more rational by attempting to improve the structure of the roof troughs that can be accommodated. When roofing a roof made of steel horizontally, connect the structures on both sides at the valley of the roof, and connect the ends of the opposite roof at the valley with the valley cap member on the top of the trough. In the connection structure of the valley part that is connected by the structure, the purlins of the structures on both sides of the valley part are connected by the connecting plate on the upper surface of the end part, and the connecting plate is also installed between the ends of the adjacent purlins. The trough gutter is installed on the upper surface of the slack, the field board, etc. supported by the connecting plate, and the trough cap member is a unitary member arranged in the length direction along the trough, and is a main body. Part and a fastening part formed by bending along both side edges. Are connected by engaging with the ends of the roof plates on both sides, and each valley cap member is a folded piece formed on the upper surface of the upper end of the main body and the lower surface of the lower end of the main body. The connecting structure of the valley part of the roof, characterized in that it is connected and fixed along the valley part by engaging with the folded piece formed on the lower edge of the door part formed on The structure of the engaging portion is specifically regulated.

Therefore, according to the present invention, when the metal roof plate is used in a lateral direction and the valley gutter is formed along the upper surface of the corner in the valley part, the roof structure and the roof plate on both sides of the trough are formed. Although connecting the ends, the connecting members are installed on the upper surface of the purlin to connect them, and the upper surface of the valley gutter is connected by the valley cap member, and the valley cap member is a bent side edge. Due to the structure of the part, the roof panels on both sides are connected without affecting the function of the trough, and the trough cap members of the unit members do not fall off along the trough due to the connection in the trough direction, which is reliable and stable. It is possible to provide a connected structure.
