Description

Description: [Industrial application] The present invention relates to a joint structure of a thatched roof in a building, and more specifically, engaging portions on both side edge portions (hereinafter, also referred to as first engaging portions). ) Is combined with a vertically-roofing roofing plate member and both end engaging portions (hereinafter, also referred to as second engaging parts) of a cap member that couples a pair of adjacent pairs of the roofing plate members. The present invention relates to the improvement of the joint structure of the vertical thatched roof.

[Conventional technology]

As a connection structure in this type of thatched roof, on the roof base member such as the main building material, the suspension members are arranged and fixed at predetermined intervals along the roof slope from the ridge side to the eaves side, and fixed. A roof plate member is laid from the left and right between the hanger members, and the engaging parts formed on the left and right side edge parts of the hanger member are locked with the engaging parts formed on the left and right side edge parts of the roof plate member. It is fitted and fixed from above by a stop member.

Then, by using a cap member in which a pair of left and right engaging piece portions are elastically opposed to and projecting from the inner edges of both lower portions, straddle members are straddled between adjacent adjoining roof plate members. ,
A structure in which each engaging piece portion of the cap member is fitted from above so as to push and spread against the elasticity thereof, whereby the both locking portions are fitted and coupled by the elastic force of the left and right engaging piece portions. It has been known.

[Problems to be Solved by the Invention]

However, the above-mentioned vertical roof joint structure is constructed so that the adjacent engaging portions of the roof plate members, which are locked to the hanger member from the left and right, straddle the adjacent engaging portions of the roof plate members, so that the cap members are attached to each other. Since the piece is elastically sandwiched and pressed to be fitted and joined, the engaging portion itself has a coupling strength, but the engaging portion of each roof plate member. Each engaging piece portion of the cap member that presses each other is in a mode in which the engaging portions are elastically sandwiched from the outside, and in particular, a means for maintaining the sandwiched state is provided. Not, the cap member, if an external force greater than the clamping force acting between the sandwiching piece portions is applied, the spacing between the sandwiching piece portions can be relatively easily expanded, The inconvenience was that the original sandwiching could not be achieved reliably.

Therefore, when a worker steps on the cap member from above during the roofing work of a vertical thatched roof, etc., the load applied from above by the worker between the sandwiching pieces of the cap member, or As a result of being spread by the reaction force,
There is a possibility that they may come off from the engagement position, or that the engagement may collapse and they may fall off each other.

Further, this drawback is exactly the same in the case of a structure in which only the engaging portion of the cap member as a single body is fitted from above and locked, and these are individually coupled.

By performing locking from the inside, auxiliary means such as preventing disengagement from the outside can be considered, but not only the connecting structure itself becomes unnecessarily complicated, but also the connecting operation becomes complicated and the work There was a problem that the sex was impaired.

The present invention is intended to improve the above problems, and when the engaging portion of the cap member is fitted onto the engaging portion of the roof plate member from above, and these are coupled to each other,
Even if an external force is applied to the cap member side, the engaging portions are configured so as not to come off from each other, so that the engaging groove of the cap member is formed on the engaging portion side of the roof plate member and is opened upward. The joint part is provided with a structure that can be engaged with the engagement groove from the inside to maintain a sufficient joint mode, and at the same time, the joint of the vertical roof with a structure capable of sufficiently preventing rainwater from flooding indoors. It is intended to provide a structure.

[Means for Solving the Problems]
