  The problem to be solved is that, firstly, a new roof can be constructed and repaired without making a hole in the existing roof, and the load such as a load on the new roof and the roof is dispersed and supported by a support member. Possible building refurbishment structure, secondly, a building renovation structure in which the support member is not blown by the wind at the time of assembly, and thirdly, with respect to the existing roof A fourth object of the present invention is to provide a building renovation structure in which the support members can be individually attached, and fourthly, a building renovation structure in which the support member can be quickly installed on the existing roof.

  In order to solve such a problem, one aspect of the present invention is to provide a concave portion on one side of a connecting portion of an exterior material formed on a mountain portion or a crosspiece, and contact with the other side portion. In the renovation structure of a building in which a new roof is constructed via a support member on each existing roof, the support member includes a support portion that crosses over two or more connecting portions of the existing roof, and the support A locking part that hangs down to the left and right end parts of the part and locks into the concave part of one of the connection parts, and a contact part of the other connection part that is suspended from the left and right other end parts of the support part The one end portion of the supporting member adjacent to the other end portion of the one supporting member, and the one end portion is formed on the other end portion. In the fitted state, the locking portion and the abutting portion face each other so that the connecting portion can be attached between the two portions. With some, and said support member adjacent is continuously formed so as to be able to linearly.

  In addition, in addition to the above-described features, the one end portion and the other end portion where the connection portion is attached are fixed by being connected by a fastening tool, and the support member is fixed to the connection portion. It is attached to the shape.

  In addition, in addition to the above-described features, the support member has a plurality of locking portions that support the horizontal portions of the plurality of connection portions and lock the concave portions of the connection portions. It is characterized by that.

  In addition, in combination with the above-described feature, the contact portion at the other end of the support portion is connected to the contacted portion while the lock portion at one end of the support portion is locked in the concave portion. It is formed so that it abuts.

  The existing roof in the present invention refers to a roof in a form in which mountain parts / valley parts, face plate parts / crosspieces such as folded plates and tiled bars are alternately connected.

  The concave part (dent part) in the connecting part of the exterior material formed on the mountain part or the pier part of the existing roof may be a wound goby shape or a fitting shape. It may be an aspect that is open or recessed in the left-right direction on the drawing, and that can lock the locking portion of the support member described later. The locking relationship between the concave portion and the locking portion includes a locking relationship that can be engaged and disengaged. The contacted portion in this connection portion is formed on the side portion opposite to the concave portion, and it is sufficient that the contact portion of the support member can contact. Moreover, it is preferable that the peak portion or the crosspiece portion in which the connecting portion of the exterior material is formed has a substantially flat portion at the top. In this case, the latching portion and the contact portion straddle the connection portion and ride on the substantially flat portion, so that the stability of the support member is improved.

  The support member includes a support portion having a substantially flat upper surface, a locking portion extending downward from one end (either left or right in the drawing) of the support portion, and a contact portion extending downward from the other end of the support portion. The support portion, the locking portion extending downward from one end of the support portion, the abutting portion extending downward from the other end of the support portion, and the other end of the support portion, An embodiment comprising a detachable locking portion, a supporting portion, a contact portion extending downward from both ends of the supporting portion, and a locking portion provided at both ends of the supporting portion and detachable from the concave portion, respectively. It becomes the thing of the aspect which consists of, etc., and becomes a elongate material which has the length which can be horizontally mounted in the some mountain part in the existing roof. The term “plurality” refers to at least two peak portions, and of course, a length that can be horizontally mounted on three or more peak portions may be used.

  The support part of the support member is a part for constructing a new exterior structure on the upper surface, and it is sufficient that a holding member or the like for holding the new roof can be attached. Therefore, various members for constructing a new roof such as bolts may be erected. The locking portion of the support member may be in a shape that can be inserted into the concave portion and locked, and may have a shape that can be locked in an engagement shape, a fitting shape, or the like, or is located in the recess. It may be in a locked state. The number of the locking portions may be the same as the number of connection portions (the number of concave portions), or may be smaller than the number of connection portions. Moreover, you may make a latching part engage / disengage with a position adjustment tool, such as a volt | bolt, in a concave part.
