Description

Description: TECHNICAL FIELD The present invention relates to a vertical roof structure for buildings, and more particularly, to a plurality of vertical roof plate members formed by raising joints on both side edges. And a crosspiece cover member that joins the connecting portions of the adjacent roofing roof plate members so as to fit each other, and relates to the improvement of the vertical roofing structure.

[Conventional technology]

As a conventional example of this type of building, a plurality of suspension members are provided along a roof slope from the ridge side to the eaves side on a roof base member such as a main building material that forms a roof hut structure of the building, They are arranged and fixed at intervals, and a vertically-roofed roof plate member (hereinafter, also simply referred to as a roof plate member) between these suspension members.
And the engaging portions formed on the left and right side edge portions of the suspension member are engaged with the connecting portions formed on the left and right side edge portions of the roof plate member, and these engaging portions are fitted from above. Each roof plate member is attached to the suspension member from the left and right by using a crosspiece cover member in which a pair of engaging piece portions are elastically opposed to the left and right lower inner edges. There is known a configuration in which the engaging piece portions of the crosspiece cover member are fitted and coupled from above so as to be spread over the adjacent mutually.

[Problems to be Solved by the Invention]

However, the above-mentioned vertically-roofed roof structure is configured so that the connecting portions of the adjacent roof plate members locked from the left and right of the suspender member are arranged so as to straddle each other by the engaging piece portions of the crosspiece cover member. Since the unitary structure of the joint itself has a sufficient joint strength because it is elastically sandwiched and pressed to be fitted and joined, the joints of the roof plate members are pressed against each other. Each engaging piece portion of the crosspiece cover member to be stopped is in a mode in which the joint portion is elastically sandwiched, and in particular, since no means for maintaining the sandwiched state is taken, When an external force greater than the sandwiching force acting between the sandwiching pieces is applied to the cover member, the sandwiching pieces are relatively easily pushed apart to achieve the original sandwiching. It caused the inconvenience of disappearing.

Therefore, when a worker steps on the crosspiece cover member from above during the roofing work of a vertical roof, the load between the pinching pieces of the crosspiece cover member from above is applied by the worker. Or, as a result of being pushed and expanded by the reaction force, there is a possibility that it may come off from the engaging position or fall off from the joint.

The present invention is intended to improve the above-mentioned problems, and the connecting portions of adjacent roof plate members that are locked to the suspension member from the left and right are straddled between them, and When the engaging piece portions of the crosspiece cover member to be fitted are elastically sandwiched and pressed to be fitted and coupled, an external force larger than the sandwiching force acting between the sandwiching piece portions is applied. Even so, it is an object of the present invention to provide a vertically-roofed roof structure having a fastening structure in which there is no fear that the holding and pressing between the connecting portions by the respective holding pieces will come off.
