Description

The present invention relates to an outer wall material joining structure and a joining joiner for joining end portions of outer wall materials such as ceramic siding.

  In general, as a form in which outer wall materials such as ceramic siding are joined in the lateral direction, so-called butt joining is known in which vertical end surfaces without step processing are joined together. In this butt joining, a so-called wet sealing method is known in which a gap between the butt portions is filled with a silicon-based sealing material, and a joint is formed by this sealing material. In the case of this construction method, in view of the problem of deterioration of the exterior design due to deterioration of the sealing material and the problem of deterioration of waterproofness, the edge of the outer wall material is subjected to jointing and the jointing part that joins the jointing parts together. A technique that eliminates the need for a sealing material by bonding is known (see Patent Document 1).

In addition, joint pricking is usually performed at a manufacturing plant and shipped after setting the outer wall material to the standard size, but depending on the construction site, the outer wall material of the standard size may not fit well. Can occur. For example, when the outer wall materials of standard dimensions are arranged as they are, the full width thereof does not match the full width of the outer wall. In such a case, it is necessary to cut the outer wall material disposed at the end to reduce the width, and to apply a jointing process to the end surface of the cut outer wall material. Thus, the jointing part processed in the construction site is joined to the jointing part of the protruding corner material, for example, so that the jointing joint at the protruding corner can be realized.
And the technique for aiming at simplification is known about the jointing process in such a construction site (refer patent document 2).

  However, such a joining structure of the outer wall material requires a dedicated cutting blade or a complicated machining operation when the outer wall material needs to be pegged at the construction site.

  Therefore, a back-up scraped portion is formed only on the end face of one outer wall material adjacent to the left and right, and this back-up scraped portion is joined to the vertical end surface of the other outer wall material that has no level difference processing. A part of the joining tool fixed to the base material is inserted into the punched portion, and the portion of the inserted joining tool and between the back-to-back scraped portion and the inserted joining tool are inserted. A configuration in which a packing material is interposed between a part and a vertical end surface without a step is proposed (see Patent Document 3). According to this, the adjustment work can be easily performed at the construction site simply by cutting one of the outer wall materials adjacent to each other.

  However, such a structure is effective when there is a sufficient distance (for example, about 15 mm) between the base material such as a pillar and the outer wall material, but the distance between the base material and the outer wall material is, for example, 2 mm. However, this method cannot be applied when a sufficient interval cannot be obtained. This is because prevention of intrusion of rainwater or the like from joints between the actually adjacent outer wall materials is not necessarily complete with a seal portion made of a packing material. For this reason, the joiner employs a configuration in which a vertical groove is further formed outside the seal portion, and rainwater or the like that has further entered the seal portion flows down from the vertical groove. This is because the vertical groove portion as described above cannot be formed when a sufficient distance cannot be obtained between the base material and the outer wall material.

  The present invention solves the above problems, and in a joint structure in which the end face of one outer wall member and the end face of the other outer wall member are abutted, a sufficient space cannot be obtained between the base material and the outer wall member. Even so, it is an object of the present invention to provide an outer wall material joining structure and a joining joiner that are excellent in waterproofness and do not impair the ease of construction.

  In order to solve the above-mentioned problem, the invention according to claim 1 is the joining of the back-end scraped portion formed on the end surface of one outer wall material constituting the outer wall of the building and the planar end surface of the other outer wall material. The outer wall material joining structure in which a concave portion is formed between the back facing scraped portion of the one outer wall material and the end surface of the other outer wall material, and the adjacent outer wall material is joined to the joint portion. A metal joiner is disposed on the back side of the inner wall, and a central portion of the joiner is inserted into the recessed portion, and both end portions of the joiner are folded back to contact the back surface of the adjacent outer wall material, The part inserted into the back-end scraped part and the part in contact with the end face of the other outer wall member and the following corner part are respectively connected to the one and other outer wall members via an elastic packing material. The one outer wall material and the other outer The rear surface of the wood, characterized in that the formation of the ventilation space between the end portion and the packing material of each part and Joyner except for the end portion of the joiner.

The invention according to claim 2 is characterized in that the one outer wall is formed at a joint portion between a back-end scraped portion formed on an end surface of one outer wall member constituting the outer wall of the building and a planar end surface of the other outer wall member. A joiner disposed on the back side of the joint portion of the outer wall material, in which a recessed portion is formed between the back-peeled portion of the material and the end surface of the other outer wall material,
A recessed groove portion provided in the center portion and inserted into the back-end scraped portion; and a plate-like portion formed at right angles on both sides of the recessed groove portion and disposed along the back surfaces of the both outer wall materials, A folded portion is formed at each end of the two plate-like portions, a step portion is provided on the concave groove portion side of the one plate-like portion, and the back of the one outer wall material of the concave groove portion. An elastic packing material is attached to each front side of the groove bottom portion corresponding to the pegging portion, the corner portion following the end face of the other outer wall member, and the step portion.

  The invention according to claim 3 is the invention according to claim 2, wherein the stepped portion is formed lower than the folded portions at both ends of the plate-shaped portion, and the difference in height between the stepped portion and the folded portion is as described above. It is characterized by being formed in approximately one-half of the packing material.

  According to the first aspect of the present invention, the metal joiner is disposed on the back side of the joint portion where the adjacent outer wall materials are joined, the central portion of the joiner is inserted into the recessed portion, and both end portions of the joiner are folded back. A portion that is in contact with the back surface of the adjacent outer wall material and inserted into the back-end scraped portion of the one outer wall material, and a portion that is in contact with the end surface of the other outer wall material and the corner portion that follows it. Are in contact with the one and the other outer wall materials through elastic packing materials, respectively, so that the portion where the packing materials are in contact is a water-stopping portion, and rainwater or the like is generated from the joint portion of the two outer wall materials. Even if it permeates, it is sealed by a water stop portion made of a packing material. In the packing material, of the groove part of the joiner, the part attached to the groove wall part on the side of the outer wall material having a planar end surface is a part that continues straight from the joints of both outer wall materials, such as rainwater Since it is easy to intrude, further sealing is secured at the part pasted on the step portion of the joiner to prevent intrusion. On the other hand, since the part sticking to the groove bottom part of the joiner is disposed at a right angle to the joint, intrusion of rainwater or the like can be reliably prevented.

  In addition, on the back surfaces of the one outer wall material and the other outer wall material, a ventilation space is formed between the portion excluding the end of the joiner and between the end of the joiner and the packing material. Even if it crosses the material and goes to the back side, rainwater etc. is discharged from the ventilation space that passes vertically. Of course, moisture contained in rainwater or the like is also discharged from the ventilation space. As described above, since the water-stopping property is good, it is possible to satisfactorily prevent mold and the like from being generated.

  Furthermore, the adjustment work can be easily performed at the construction site simply by cutting the outer wall material having a planar end surface in the adjacent outer wall material. Further, since no sealing material is used, there is no problem of deterioration or maintenance of the sealing material.

  As described above, even when a sufficient space cannot be obtained between the base material and the outer wall material, the outer wall material joining structure is excellent in waterproofness and does not impair the ease of construction. Can be provided.

  According to the invention of claim 2, the joining joiner includes a concave groove portion provided in the central portion, and plate-like portions formed at right angles on both sides of the concave groove portion, and each of the two plate-like portions. A folded portion is formed at the end, and a step portion is provided on the concave groove side of the one-side plate-like portion, and the concave groove portion is inserted into the back-end scraped portion of one outer wall material, The shape portion is arranged along the back surfaces of both outer wall materials, and the folded portion at each end of both plate-like portions is arranged along the back surfaces of both outer wall materials. Since the packing material having elasticity is attached to the groove bottom portion corresponding to the cut portion, the corner portion continuing to the end face of the other outer wall material, and the front side of the step portion, the portion where the packing material abuts is stopped. Even if rainwater or the like enters from the joint between the two outer wall materials, it is sealed by a water stop portion made of a packing material.

  Further, when the plate-like portions on both sides of the joiner are brought into contact with the back surface of the outer wall material, the folded portions at both ends of the plate-like portion actually come into contact. Further, the packing material also directly contacts the back surface of the outer wall material. Since the other part floats from the back surface of the outer wall material, a ventilation space passing in the vertical direction is formed in the floated part. Therefore, even if rainwater, etc. travels over the packing material to the back side, the moisture contained in the rainwater, etc. or rainwater is discharged from the vertically ventilated space, and mold is generated. It can prevent well.

  Therefore, even when there is not enough space between the base material and the outer wall material, we provide a joiner for the outer wall material that has excellent waterproof properties and does not impair the ease of construction. can do.

  According to the invention of claim 3, the step portion of the joiner is formed lower than the folded portion at both ends of the plate-like portion, and the difference in height between the step portion and the folded portion is Since the packing material is formed in almost half, when the packing material is pressed against the back surface of the outer wall material, it is crushed and becomes about half the thickness. Therefore, the just good water stop function is obtained.

A space S is formed between the back surface of each outer wall member 6, 6 and the vertical trunk edge 4 by the fastener 9.

  As shown in detail in FIG. 2, both outer wall materials 5, 6 are a back-end scraped portion 7 formed on the end surface of the first outer wall material 5, and a planar end surface of the second outer wall material 6. 8 are joined in a butted state. Thereby, a recessed portion 10 is formed between the back-end scraped portion 7 of the first outer wall material 5 and the end surface 8 of the second outer wall material 6. In addition, a metal joining joiner 11 is disposed on the back side of the joint where the outer wall materials 5 and 6 are joined.

  As shown in FIGS. 2 and 4, the joiner 11 includes a concave groove portion 12 provided in the central portion and inserted into the concave portion 10 formed by the back-to-back scraper portion 7, and both sides of the concave groove portion 12. The plate-like portions 13 and 14 are disposed at right angles to the outer wall materials 5 and 6 and are disposed along the back surfaces of the outer wall materials 5 and 6, and the packing material 15. The plate-like parts 13 and 14 on both sides are formed to be flush with each other.

  The recessed groove portion 12 is formed in a shape that fits substantially into the recessed portion 10 of the joint portion between the outer wall materials 5 and 6. Further, a folded portion 16 is formed at each end of both plate-like portions 13 and 14. Further, a stepped portion 17 is provided on the side of the groove portion 12 of the plate-like portion 14 on one side. The height h1 of the stepped portion 17 is formed to be about half of the height h2 of the folded portion 16. Further, the width of the stepped portion 17 is formed substantially the same as that of the one plate-like portion 13 and is formed to be about one third of the width of the other plate-like portion 14.

  The packing material 15 is made of an elastic material such as rubber or resin. The packing material 15 is attached in a Z-shape to each front side of the groove bottom portion 12 a, the groove wall portion 12 b, and the stepped portion 17 corresponding to the back-end scraped portion 7 of the recessed groove portion 12. The height h1 of the stepped portion 17 of the joiner 11 and the thickness of the packing material 15 are set to be higher than the height h2 of the folded portion 16. In addition, the thickness of the packing material 15 is formed to be substantially the same as the height of the folded portion 16.

  Next, when joining the said 1st outer wall material 5 and the 2nd outer wall material 6, as shown in FIG. 2, the concave groove part 12 of the center part of the joiner 11 is included in the back-up scraping part 7. Insert into the recessed portion 10. Further, the folded portions 16, 16 at both ends of the joiner 11 are in contact with the back surfaces of the first and second outer wall members 5, 6. At this time, the portion inserted into the back-end scraped portion 7 of the first outer wall material 5, the end surface 8 of the second outer wall material 6, and the following corner portion 18 are first through the packing material 15. And abut against the second outer wall materials 5 and 6. Thereby, the part which the packing material 15 contact | abutted comprises the water stop part. In addition, a ventilation space s <b> 1 is formed on the back surface of the second outer wall material 6 in a portion excluding the end portion of the joiner 11. Further, a ventilation space s <b> 2 is formed between the end of the joiner 11 and the packing material 15 on the back surface of the second outer wall material 6.

  As described above, the metal joiner 11 is disposed on the back side of the joint portion between the first outer wall member 5 and the second outer wall member 6, and the central portion of the joiner 11 is inserted into the back-end scraping portion 7. The folded portions 16 at both end portions of the joiner 11 are in contact with the back surfaces of the adjacent outer wall materials 5, 6, the part inserted into the recessed portion 10 of the first outer wall material 5, and the end surface of the second outer wall material 6. 8 and the portion that is in contact with the corner 18 that follows are in contact with the first and second outer wall materials 5 and 6 via the elastic packing material 15, respectively. The contacted part becomes the water stop part. Therefore, even if rainwater or the like enters from the joint between the first outer wall material 5 and the second outer wall material 6, it is sealed by the water stop portion by the packing material 15. In addition, the part stuck to the groove wall part 12b by the side of the 2nd outer wall material 6 of the groove part 12 of the joiner 11 among the packing materials 15 is a junction part of both the outer wall materials 5 and 6, ie, a 1st outer wall. Provided in a portion that is straight and continuous with a gap (joint) 21 between the butted portion of the end surface 8 excluding the back-jacketed portion 7 of the material 5 and the end surface 8 of the second outer wall material 6, and other portions Since rainwater and the like are more likely to enter compared to the above, further sealing is performed at a portion attached to the stepped portion 17 of the joiner 11 to prevent intrusion. On the other hand, since the part stuck to the groove bottom 12a of the joiner 11 is disposed at a right angle to the joint gap 21, the intrusion of rainwater or the like can be reliably prevented.

  By the way, there is a possibility that rainwater or the like may pass over the packing material 15 to the back side. In such a case, the back surface of the first outer wall material 5 has a ventilation space s1 in a portion excluding the folded portion 16 at the end portion of the joiner 11, and the back surface of the second outer wall material 6 has an end portion of the joiner 11. Since the ventilation space s2 is formed between the folded portion 16 and the packing material 15, rainwater and the like are discharged from the ventilation spaces s1 and s2 that pass in the vertical direction. Of course, moisture contained in rain water or the like is also discharged from the ventilation spaces s1 and s2. As described above, since the water-stopping property is good, it is possible to satisfactorily prevent mold and the like from being generated.

  In addition, it is only necessary to cut the second outer wall material 6 into a flat shape between the adjacent outer wall materials 5 and 6, and no special step processing such as jointing is required. Work can be done. Further, since no sealing material is used, there is no problem of deterioration or maintenance of the sealing material.

  The height h1 of the stepped portion 17 of the plate-like portion 14 on one side of the joiner 11 is approximately one half of the height h2 of the folded portion 16, and the thickness t of the packing material 15 is the folded portion. 16 is formed so as to be substantially the same as the height h2, the packing material 15 is crushed by about half when the second outer wall material 6 is attached, and a good water stop portion is formed.
