Description

Description: TECHNICAL FIELD The present invention relates to a structure for connecting plate members to each other in a building, and more specifically, for example, engaging portions (hereinafter referred to as a (1) also referred to as 1 engaging part) and a vertically-roofed roof plate member (hereinafter, also simply referred to as a roof plate member), and both ends of a beam cover cap member for connecting a pair of adjacent roof plate members to each other. In a vertically-roofed roof or the like configured by combining and engaging with an engaging portion (hereinafter, also referred to as a second engaging portion for convenience of description), the present invention relates to an improvement in the connecting structure of these plate members. is there.

[Conventional technology]

As a joint structure of plate members in a general building of this kind, for example, in this case, a joint structure of a thatched roof, usually, on a roof base member such as a main building material which becomes a roof hut structure of the building. At this point, suspender members are arranged and fixed at predetermined intervals along the roof slope from the ridge side to the eaves side, and roof plate members are interposed from the left and right between these respective suspender members and suspended. The engaging portions formed on the left or right edge of each roof plate member are engaged with the engaging portions formed on the left and right edges of the child member to form a pair of left and right members. By using a crosspiece cover cap member in which the stopper portion is fixed by a pressing member that is fitted from above, and a pair of left and right engaging piece portions are elastically projectingly opposed to each other on the inner edges of both lower portions. Straddle between the adjacent roof plate members that are attached to the suspension member from the left and right The engaging pieces of the crosspiece cover cap member are fitted from above so as to push and spread against the elasticity, and thus the both locking portions are capped by the elastic force of the left and right engaging pieces. Combined configurations are known.

[Problems to be Solved by the Invention]

However, in the conventional joint structure for a thatched roof configured as described above, the adjacent engaging portions of each roof plate member that is locked to the suspension member from the left and right are straddled between them. Since the engaging pieces of the crosspiece cap member are elastically clamped and pressed for capping connection, the locking portion itself has a sufficient connection strength. However, with regard to each engaging piece portion of the crosspiece cover cap member that holds the engaging portions of the roof plate members together, this does not make it possible to elastically sandwich the engaging portions from the outside. In particular, since no means for holding the sandwiched state is provided, an external force greater than the sandwiching force acting between the sandwiching pieces is applied to the crosspiece cover cap member. When added, a comparison is made between each of these sandwiching pieces. Such that readily the spreading connexion, resulting in inconvenience that the original clipping no longer achieved with certainty.

That is, to be more specific, during such a roofing work of a thatched roof or during repair work,
When an operator steps on the crosspiece cap member from above (generally, the worker has a subconscious consciousness that the roof surface will not be damaged, and therefore, it is often determined that it will be even stronger. In the part including the attachment part, this is the case where the crosspiece cover cap member surface is stepped on from above in many cases.) The load from the upper side or the reaction force pushes it out relatively easily, and when it disengages from its engagement position, or when it is severe, the engagement collapses and the two fall off each other. Even so, the sandwiching action was significantly impaired.

Further, this drawback is not necessarily limited to such a form, that is, the coupling structure between the left and right pair of the engaging portion and the engaging piece portion, and more simply than this, one of The same applies to the case where the second engaging portion of the other plate member is locked and coupled to the first engaging portion of the plate member.

And as a way to avoid this, for example,
It is conceivable that auxiliary means such as newly fastening the first and second engaging portions of the respective plate members to be joined by another member from the outside can be considered. To take such a supplementary means means that the connecting structure itself becomes complicated without exception, and at the same time, the connecting operation becomes complicated and the workability is deteriorated. It was.

The present invention has been made in order to improve the conventional problems as described above, and an object thereof is to make an engaging portion of one plate member and an engaging portion of the other plate member mutually. In this case, even if an external force is applied to each of these plate members, this type of joint structure has such a structure that there is no fear that the coupling mode between the respective engaging portions will be broken and will be disengaged. An object of the present invention is to provide a structure for connecting plate members to each other in a building.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the structure for connecting the plate members to each other in the building according to the present invention has an abutting support portion formed by bending at least an upper end portion of a side edge portion, and the abutting support portion is bent downward. And one plate member including the engaging groove portion formed in the folded-back portion and raised in the folded-back portion, and the extension portion raised from the engaging groove portion, and elastically extended at least toward the butting support portion. A locking member having a locking piece formed with the front end as a locking edge, and an abutting lower edge that is bent and formed at least at the lower end edge of the side edge and abuts the abutting support portion, An engaging recess formed on the bent inner edge side of the abutting lower edge portion and locked by the engaging edge, and extending inward and downward from the abutting lower edge portion, the engagement The other of the engaging piece that is inserted and engaged in the groove It is constructed by a member.

[Work]

That is, in the present invention, the abutment support portion of one plate member is made to face the abutment support portion of the elastically extended engagement piece portion of the engagement member while facing the other end thereof. With the engaging piece of the plate member, the engaging piece of the engaging member is repulsed against elasticity while being repelled, until the lower edge of the abutting support is abutted. By inserting and engaging the piece into the engaging groove of one plate member, the repulsion of the engaging piece by the engaging piece is released, and with the elastic return of the engaging piece, The locking recesses are locked by the front end locking edges of the locking pieces, and the plate members are restrained from each other in the vertical and horizontal directions in such a manner that the plate members are restrained from each other. It can be combined as expected.
