Therefore, it is possible to maintain the watertightness by following the slight variation in the joint size and maintaining the pressure contact state with the inner surface of the joint groove. The joint finishing material combines the makeup of joint grooves and waterproofing. When the leaf spring-like waterproof material is composed of a leaf spring and a soft material, the restoring force of the leaf spring provides a pressing force against the inner surface of the joint groove, and the soft material provides close contact with the inner surface of the joint groove. Therefore, a strong pressing force provides high adhesion and excellent waterproofness.

事完了後でも点検が容易に行える。With this structure, the joint finishing material 8 and the leaf spring-like waterproof material 7 are doubly waterproofed, and the waterproofness is enhanced. The leaf spring waterproof material 7 has a corrugated cross-section portion 7a on the web portion.
Since it is composed of a groove-shaped leaf spring, it is possible to obtain elasticity with an appropriate elastic coefficient over a wide displacement range. Therefore, the pressure contact state with the inner surface of the joint groove can be maintained by following a slight variation in joint size, and the rainwater can be reliably stopped. Therefore, the degree of freedom is high. Further, even if the joint width varies with the expansion and contraction of the outer wall material 5 after the construction, the variation can be followed and stable waterproofness can be obtained. Since the joint finishing material 8 is made of an elastic material such as rubber, it also serves as a makeup for the joint groove 2 and it is easy to match the color even when the outer wall material 5 is pre-coated. Moreover, stains are unlikely to occur. Furthermore, since the construction can be carried out by a dry construction in which the leaf spring waterproof material 7 and the joint finish material 8 are simply press-fitted, the sealing work is simple, no sealing specialist is required, and the quality of the worker is not affected by the skill. In addition, inspection can be performed easily even after the sealing work is completed.

It consists of and. The metallic leaf spring 12 is of an outward groove type having a corrugated cross-section portion 12a at the center of the web portion. The soft material 13 is made of soft rubber, synthetic resin, or the like, and has a plurality of elastic fins 13a on the outer side surface. The other structure is the same as that of the above embodiment. In the case of this configuration, the restoring force of the metal leaf spring 12 provides the pressing force to the inner surface of the joint groove 2, and the soft material 13 provides the adhesion to the inner surface of the joint groove. Therefore, a strong pressing force provides high adhesion, and further excellent waterproofness can be obtained.
