[Problem that the idea aims to solve]

However, conventional dry joint jobs, such as those illustrated in FIGS. 5 and 6, Inner (C) and (S) have superior characteristics compared to other joint joiners. However, if the surface has an uneven pattern as shown in FIG. It was unsuitable for use in the joint (chi) of the dressing material (ta). That is, in Figure 6 When joining exterior materials (T) using the dry joint joiner (S) illustrated, The end sealing piece (S) of the upper member (C) is the end sealing piece (S) on the end (TE) surface of the convex part (T) of the exterior material (T). It only covers the surface, and a gap is created between the concave part (G) and the joint part (C). The waterproofness of the container will be reduced. In addition, the exterior formed by the recess (G) Since the horizontal joints of the timber (T) are blocked by the dry joint joiner (S), the appearance is It is not desirable from the point of view of craftsmanship either. On the other hand, the dry joint joiner illustrated in Figure 5 - In the case of (C), place the joint cushion piece (Ke) on the concave part (G) surface of the exterior material (T). It can be used according to the height of the surface, but the convex end surface (na) is exposed. The appearance design quality will deteriorate, and there is a greater risk that the end of the wood will chip and fall off. Which drawbacks does it have?

[0006] This idea was made in view of the above circumstances, and it Eliminates the defects of the joiner, and if the exterior material to be joined has an uneven pattern on its surface. In addition, it improves the water resistance and frost damage resistance of the joint, and improves the appearance and design. The objective is to provide an improved dry joint joiner that is easy to manufacture and It is said that

【Example】

Below, we will explain this invention in more detail by showing examples along with the attached drawings. I will clarify. FIG. 1 is a cross-sectional perspective view illustrating the structure of the dry joint joiner of this invention. For example, in this example, the dry joint joiner (1) has a top part (2) and a bottom part. It consists of two members, member (3), and these members are removable. Ru. The lower member (3) is made of a hard flame-retardant resin material such as vinyl chloride, and is made of a pair facing each other. A vertical side plate (4) is installed upright on the bottom plate (5), and the bottom plate (5) is made of a thin metal plate. It also has a reinforcing core (6). The bottom plate part (5) consists of a single surface and has a reinforcing core ( 6), when fixing the lower member (3) to the exterior base material, the construction Good linearity can be achieved. In addition, the bottom plate part (5) is provided with rainwater as in the conventional example. A draining fin (7) may also be provided to prevent water from entering.

[0011] On the other hand, the upper member (2) is entirely made of a soft material such as rubber, and the end of the exterior material to be joined The end sealing piece (8) that comes into contact with the end face of the edge and the joint cushion that comes into contact with the end face of the exterior material. The protrusion (1) is inserted and fixed between the piece (9) and the vertical side plate (4) of the lower member (3). 0). The end sealing piece (8) has a step on the surface corresponding to the uneven pattern on the surface of the exterior material. Ru. In other words, the upper end sealing piece (8) seals the convex end surface of the exterior material. Also, the joint sealing piece (8') located at a sunken position is located on the butt end surface of the concave part of the exterior material. It is designed to seal.

0012 It should be noted that, including the end sealing pieces (8) and (8'), the parts exposed on the surface of the upper member (2) Apply a paint such as chlorosulfonated polyethylene (CSM) to the area Or the exterior has various colors by making it a material that can be made into a sheet. It is also possible to use the upper member (2) of the same shape for materials. In addition, the joint cushion piece (9) is formed horizontally and is always at a constant position. It comes into contact with the end face of the exterior material. In addition, this joint cushion piece (9) It is also possible to provide a step according to the shape of the end sealing pieces (8) (8'). In addition, the number of pieces is not just one pair, but multiple pairs depending on the thickness of the exterior material to be joined. You can also.

[0013] Furthermore, the protrusion (10) has two pairs of small fitting protrusions (11) on both end faces thereof. Due to this elastic force, the lower member (3) is fitted and fixed between the vertical side plates (4). It is supposed to be done. Therefore, the insertion depth of the protrusion (10) can be adjusted to a certain extent. It is possible to make a clause. Figures 2 and 3 show the connection of exterior materials using this dry joint joiner (1). It is a front sectional view showing a case. Figure 2 shows that the dry joint joiner (1) has uneven surfaces. This figure shows the state in which the convex end surface (13) of the patterned exterior material (12) is joined. The end sealing piece (8) of the upper member (2) comes into contact with the end edge surface (14) of the convex part. are doing. On the other hand, Fig. 3 shows that the same dry joint joiner (1) is used for the exterior material (12). This shows the state in which the end faces (15) of the recess are joined, and the end sealing piece (8') is in contact with the end surface (16) of the concave end to seal it.

[0014] In this way, the end sealing pieces (8), (8') of the upper member (2) are respectively attached to the exterior material ( 12), the convex end end surface (14) and the recess end end end surface (16) are completely sealed. Moreover, the joint cushion piece (9) is covered by the exterior material (9) due to its soft elasticity. 12) Because it flexibly responds to dimensional changes due to expansion and contraction, etc., and always adheres closely to the end surface, The waterproofness of the joint is good, and the appearance and design of the exterior material joints are also improved.

【0015】 Of course, this invention is not limited to the above examples, and The uneven shape of the surface of the covering material, the corresponding surface shape of the joint sealing piece, or the like. Regarding the detailed structure of the other upper and lower members, various aspects are possible. Needless to say.
