2. Description of the Related Art A dry siding material for forming a wall of a building is a paper in which a synthetic resin foam is filled in a gutter-like metal plate and a back surface of which is laminated with aluminum as required. There is a metal siding material covered with a back material such as a metal plate or a metal plate, and a ceramic siding material manufactured from cement, concrete, or the like, and those formed to predetermined lengths are used.

[0003] In such a siding material, engaging portions for engaging the widthwise edges of the siding material fixed adjacently to each other are formed at both ends in the width direction which is generally parallel to the longitudinal direction. One of the engaging portions is provided with a fixing portion that is fixed to a building frame by nails, screws, or the like. And, in order to fix the siding material in the width direction, after engaging the other engagement portion of the siding material fixed next to one engagement portion of the siding material fixed earlier,
When renovating pillars, studs, hulls and existing walls, work to fix them directly on existing wall materials or to frames such as hulls newly fixed on existing wall materials with tapping screws or other fixtures It is repeated sequentially.

In order to connect the siding material in the longitudinal direction, the siding material is not only poor in appearance when the longitudinal edges of the siding material are merely butted against each other, but also rainwater enters from the cut surface. When the siding material is a metal siding material, a phenomenon occurs in which the metal plate or the synthetic resin foam corrodes, so whether the siding material is a metal siding material or a ceramic siding material, it is adjacent in the longitudinal direction. A connecting material is used between the longitudinal edges of the siding material to cover the longitudinal edges.

The connecting member is generally composed of a fixing member and a cap. For example, as shown in FIG. 5, a fixing member 2 fixed to the frame 6 by nails or tapping screws is used.
a ′ has a widthwise outer surface side of an engaging piece 2aa ′ protruding outward at a widthwise central portion thereof, and has a sawtooth-shaped cross section, and a longitudinal edge 1a of the siding material 1. A coupling member 2 'is formed, in which a cap 2b' for covering the front surface is formed on the back surface thereof with an engaging piece 2ba 'engaging with the engaging piece 2aa' of the fixing member 2a 'in a shape having a saw-toothed cross section facing the engaging piece 2ba'. can do.

In order to connect the siding material 1 in the longitudinal direction using such a conventional connecting member 2 ′, first, the fixing member 2 a is previously attached to the frame 6 where the longitudinal edge 1 a of the siding material 1 is located. Is fixed with a fixing tool 7 such as a nail or a tapping screw. Then, the siding material 1 is disposed on both sides of the engaging piece 2aa 'of the fixing member 2a' such that the longitudinal edge 1a is close to the engaging piece 2aa 'of the fixing member 2a'. In each of the siding materials 1, a fixing portion extending to one end in the width direction is fixed to the frame 6 by a fixing tool 4 such as a nail or a tapping screw. Siding material 1 to be fixed to
The longitudinal edge portion 1a is the engaging piece 2a of the fixing member 2a '.
a ', and the engaging portion formed on the other widthwise edge is engaged with the engaging portion formed on one widthwise edge of the fixed siding material 1. After the joining, a fixing portion formed at one end in the width direction of the siding material 1 to be fixed next is fixed to the frame 6 by a fixing tool 4 such as a nail or a tapping screw. After repeating this operation in the width direction of each siding material 1, the cap 2b '
The back of the engaging piece 2ba 'has already been fixed by the fixing member
The siding material 1 is connected so as to conceal the longitudinal edge 1a thereof by being pushed into and engaged with the engaging piece 2aa 'of 2a' from outside.

However, in the method of connecting the siding material 1 in the longitudinal direction using the conventional connecting member 2 'as described above, the engaging piece 2aa' having a sawtooth cross section formed on the fixing member 2a 'is used. Since the engaging piece 2ba 'formed in the cap 2b' and having a sawtooth cross section is engaged, once the cap 2b 'is engaged with the fixing member 2a', the fixing member 2a 'and the cap 2b' are separated. Can not be performed, and when it is desired to finely adjust or replace only a certain siding material 1 after construction, both the fixing member 2a 'and the cap 2b' must be exchanged. Replacing 2a 'has the disadvantage that workability is extremely poor, since the whole work must be restarted from the beginning.
