[Action]

First, the construction of the envelope by the folded plate-like architectural plate A will be described. A plurality of metal fittings 5, 5,... Are placed and fixed on the structural material 7, and the predetermined metal fittings 5, 5,. Are mounted and fixed to them. Next, the construction plate A is arranged between the adjacent metal fittings 5, 5, and the vertical connecting portion 2 is wound around the tongue piece 6a of the hanging member 6,
An architectural gasket B housed in the cap-shaped connecting portion 3 of the adjacent building plate A is inserted into and fixed to the vertical connecting portion 2 to form an envelope.

The construction order is as follows. First, the building gasket B is fitted to the existing vertical connecting portion 2 of the building plate A, and then the capping connection of the building plate A adjacent to the building gasket B is performed. The part 3 may be fitted, and is constructed according to the situation at the construction site.

At this time, in the intermediate chevron formed on the main plate 1, the fitted bent portions 4, 4 are fixed by the fitting projections 5 a, 5 a of the receiving fitting 5,
The building plate A is fixed on the structural material 7.

Further, in the case of the grooved plate-like building plate A, as shown in FIG. 12, the connection structure other than being attached to the base plate 8 on the structural material 6 via the hooks 6 is the same as the connection structure described above. It is the same as the case of FIG.

〔The invention's effect〕

In the present invention, a building plate A in which a vertical connecting portion 2 is formed on one side in the width direction of the main plate 1 and a cap-shaped connecting portion 3 is formed on the other side.
And both side walls 9a, 9a in a holding body 9 having a substantially inverted U-shaped cross section.
A plurality of pressing ridges 10 facing each other are formed in the inside, and a cap-shaped connection to the vertical connection portion 2 via a building gasket B in which a circular contact portion 11 having a circular cross section is formed at the tip of the pressing ridge 10. Due to the joint structure of the outer body in which the part 3 is fitted, firstly, the construction can be performed easily and quickly, secondly, the watertightness can be excellent, and thirdly, the durability is excellent. And so on.

To explain these effects in detail, in the construction gasket B constituting the present invention, a plurality of opposing pressing ridges 10 are formed in both side walls 9a, 9a in the holding body 9, and the pressing ridges 10 are formed.
The architectural gasket B having a circular contact portion 11 having a circular cross section formed at the tip of is connected to the vertical connecting portion 2 or the architectural gasket B is inserted into the cap-shaped connecting portion 3. When the object is fitted into the vertical connecting part 2, the point of contact between the circular contact part 11 and the vertical connecting part 2 becomes a point contact p (see FIG. 16). Since the frictional force generated between the contact portion 11 and the vertical connecting portion 2 is small, the worker can perform the construction with a small force accordingly. On the other hand, in the connection between building plates using a conventional type gasket, as shown in FIG. 17, since a contact portion or the like is not formed at the tip of the pressing ridge, the pressing ridge and the rising Was caused by the surface contact s, and the frictional force increased accordingly, and the worker was burdened during the construction. According to the present invention, the frictional force at the time of mounting can be smaller than that of the conventional product, so that the burden on the worker at the time of construction can be reduced and the working efficiency can be improved (see FIGS. 15 and 16). .

Further, the architectural gasket B constituting the present invention has a small frictional force because the circular contact portion 11 and the connecting portion 2 of the architectural plate A are in point contact p as described above, and the architectural plate A is Even if expansion and contraction due to thermal expansion occurs, there is also an advantage that the building gasket B and the building plate A slide well, and the generation of internal stress, squeaking noise, and the like can be prevented.

Next, since the circular contact portion 10 is formed in a circular cross section, the point of contact with the vertical connecting portion 2 of the building plate A is always constant as a point contact. By pressing the connecting members 2 of the building plate A facing each other with substantially the same pressing force via the pressing ridges 10, 10,...

Next, when the circular contact portion 10 comes into contact with the vertical connecting portion 2 via the pressing ridge 10, the pressing ridge 10 bends, but the elastic restoring force against the bending (see FIG. 14) increases the strength. It can be pressed with an appropriate pressing force.

As described above, the architectural gasket B once attached is extremely hard to be detached, and is extremely excellent in that it has both the advantage of being easily attached as described above and the conflicting property of being easily attached and hardly detached.
