Description

  The present invention relates to a connecting structure and a connecting method for a horizontal covering material that is easy to align with a joint member and excellent in workability.

  A structure in which the left and right edges of the roof board are inserted and connected to lateral insertion grooves formed in the connecting member is often employed when connecting the metal side roof boards in the longitudinal direction (for example, Patent Document 1, Patent Document 1). 2).

In patent document 1, it is a connection member which connects the roof board 4 with the connection member 5 of the cross-section H shape which consists of the lower board 6, the upper board 7, and the cover board 8, Comprising: The edge of the roof board 4 is made into the lower board 6 And the cover material 8.
In patent document 2, it is a connection member which connects the surface structure 8 with the joint main body 1, Comprising: It is the structure which mounts the edge of the surface structure 8 in the clamping groove 2 formed in the joint main body 1. FIG.
No. 3-10249 No. 3-10251

However, in these Patent Documents 1 and 2, since the connecting edge of the roof plate is flat in plan view (the connecting edge is linear), it is difficult to align the connecting member with the insertion groove.
Moreover, in patent document 1, since the eave side of a connection member is also bent in the substantially same shape according to the eaves side goby part of a roof board, the insertion groove of a bending part is crushed and it becomes difficult to insert a roof board. , There was a risk of problems that could not be inserted.

The present invention has been proposed in view of the above, and is a joint in which a lateral covering material having a molding portion is provided on the eave side and the ridge side of the face plate portion, and a connecting portion is provided on the back surface of the decorative portion and the decorative portion. A connecting structure for connecting in the direction of girder by a member, wherein the lateral covering material is formed with a concave notch portion in a horizontal direction in plan view on at least one of the left and right end edges of the face plate portion, and the connecting portion of the joint member The side edge of the decorative part is folded back to the back side, and an insertion groove is formed by an upper side part extending inward, a wall part obtained by folding the inner end of the upper side part, and a lower side part extending outward from the wall part. The present invention relates to a connecting structure for a horizontal covering material in which the bottom end of the connecting portion of the joint member is in contact with a notch portion of the horizontal covering material in the assembled state.
In the present invention, the eaves ridge direction indicates the short direction and the water flow direction, and the left and right direction indicates the longitudinal direction and the girder direction.

  Moreover, the connection structure of the said horizontal covering material in which the right-and-left edge of a horizontal covering material can be connected in superposition | polymerization is also proposed.

  Furthermore, the connection structure of the said horizontal covering material whose lower side part of the connection part of a coupling member is upward convex is also proposed.

  Further, the present invention provides a lateral covering material having molding parts on the eaves side and the ridge side of the face plate part, and a joint member in which a connecting part is provided on the back surface of the decorative part and the decorative part. In the connecting method for connecting, the lateral covering material is formed with at least one of the left and right end edges of the face plate portion to form a concave cutout in a horizontal direction in plan view, and the connecting portion of the joint member has a decorative portion side edge. A joint member is formed by forming an insertion groove by an upper side portion folded back to the back side and extending inward, a wall portion folded back from the inner end of the upper side portion, and a lower side portion extending outward from the wall portion This also proposes a method for connecting a side-facing exterior material, characterized in that the notch is inserted into the insertion groove and assembled so that the lower end of the connecting portion is in contact with the notch portion of the side-facing exterior material. is there.

  According to the connecting structure and connecting method of the horizontal sheathing material of the present invention, a concave notch is formed in a horizontal direction in a plan view on at least one of the left and right edges of the face plate portion, and the water lower end of the joint member connection portion is Since it is only necessary to insert and insert the notch into the insertion groove so as to be brought into contact with the notch, alignment with the joint member is easy and workability is improved. Then, the movement of the joint member in the flow direction can be restricted by the contact portion of the joint member coming into contact with the cutout portion of the side covering material, and the joint member is not displaced after the side covering material is laid. Furthermore, since the insertion groove does not reach the molding part on the eaves side and the ridge side, no crushing occurs and no problem occurs when the notch part is inserted.

In particular, when the left and right edges of the outer covering material can be connected in a superposed manner, locations other than the notch (remaining face plate, eaves side molded part, etc.) are connected in a superposed manner to prevent rainwater from entering, resulting in makeup. The length of a part can be shortened and the design property becomes favorable.
That is, for example, as in the above-described prior art, when the connecting edges of the roof boards adjacent in the longitudinal direction are flat in plan view (the connecting edges are straight), there are gaps at predetermined intervals between the edges of the roof boards. It is necessary to close the gap with the connecting member, but it is extremely difficult to close the gap between the edges of the roof plates that are bent in a complicated manner with the connecting member, especially in the thickness direction. As a result, there was a risk of problems in the rain.

  In addition, by forming the lower side of the connecting part of the joint member in an upwardly convex shape, an upward elastic force acts on the lower side in the assembled state. Etc.), and further, the notched portion of the side covering material inserted into the insertion groove can be held in a sandwiched manner.

The side facing exterior material used in the present invention (hereinafter simply referred to as exterior material) is provided with a molded part on the eaves side and the ridge side of the face plate part, and by blanking or the like, at least one of the left and right edges of the face plate part, It is the structure which formed the notch part of the concave shape sideways in planar view.
The face plate portion is substantially flat and does not particularly limit the shape or the like.
Further, the shape of the molded part is not particularly limited as long as it is connected by engagement or fitting, and more specifically, in a connected state, a part of the molded part is combined in a superposed state to be engaged or engaged. It is to be fitted.
Further, the notch portion corresponds to at least the insertion groove of the joint member in the assembled state, and means that the end edge is formed in a concave shape in a plan view, and may be provided on both the left and right end edges. However, you may provide only in either one edge. Further, the number of the concave portions (notches) may be one or more, and it may be provided in a part of the face plate portion or in almost the entire region. Furthermore, the edges other than the notch are opposed (adjacent) or overlapped. Although such a concave portion is referred to as a notch portion, the molding method is not particularly limited. Therefore, in terms of shape, a convex portion (opposing portion or overlapping portion) in a horizontal direction is provided on a flat end edge. It can be paraphrased as a thing.

The joint member used for this invention is the structure which provided the connection part in the back surface of the decorative part and this decorative part.
The decorative part is formed in the same shape as the face plate part.
In addition, the connecting portion has a decorative portion side edge folded back to the back side, an upper side portion extending inward, a wall portion folded back from the inner end of the upper side portion, and a lower side portion extending outward from the wall portion And a lateral insertion groove is formed, and the cutout portion of the exterior material is inserted in the assembled state.
Furthermore, the wall part and lower side part which form the said insertion groove | channel may be the same length or a different length in a flow direction. However, the wall portion is formed to have a length equal to or less than the length of the cutout portion of the exterior material in the flow direction, but the lower side portion has a length equal to or less than that of the face plate portion even if formed to have almost the same length as the face plate portion. May be.

  And the connection structure of the exterior material of the present invention is such that in the assembled state, the water lower end of the connection portion of the joint member abuts the notch portion of the exterior material, and in that state, the notch portion is formed in the connection portion (insertion groove). What is necessary is just to insert and assemble | attach, the position alignment to a joint member is easy, and workability | operativity improves.

  In particular, when the left and right edges of the exterior material are formed so that they can be connected in a superposed manner, locations other than the notches (remaining face plate portion, eaves-side molded portion, etc.) are connected in a superposed manner, preventing rainwater from entering. The length of the decorative part can be shortened and the design is improved.

In addition, when the lower side portion of the connecting portion of the joint member is formed in an upwardly convex shape, an elastic force is exerted on the lower side portion in the assembled state, so that the exterior material may or may not have a backing. Further, since a force for pushing up the cutout portion of the exterior material inserted into the insertion groove from below (elastic force upward of the lower side portion) works, the cutout portion can be held in a sandwiched manner.
In other words, when the thickness (height) of the insertion groove and the thickness of the exterior material are tight (when the dimension setting is strict), the backing of the edge portion of the exterior material is formed when the exterior material is molded (during processing) In some cases, it may be necessary to change the processing method or to remove the backing applied to the edge on site.
