Description

  The present invention relates to a method for constructing a building outer wall using an outer wall material (including a corner corner material) such as ceramic siding.

  Conventionally, as a form of joining outer wall materials such as ceramic siding, four sides of a rectangular plate-like outer wall material are subjected to jointing, a horizontal joint between the upper and lower outer wall materials, and the left and right outer walls A construction method is known in which a joint joint is formed at each longitudinal joint of the material (see Patent Document 1).

  In addition, the four sides of the rectangular plate-shaped outer wall material are shipped after being jointed at the factory, but usually the width of the outer wall material must be adjusted at the construction site. It will be. This is because the width dimension of the outer wall material is standardized, and it is difficult to match the width dimension of the entire outer wall only by arranging the standardized width dimension.

  Therefore, at the construction site, the width of the outer wall material is adjusted by cutting to adjust the size, and the cut end face is subjected to jointing, so that jointing is also performed on the dimensionally adjusted outer wall material. It is known to do. In addition, there is also known a technique for improving the workability of the jointing process at such a construction site (see Patent Document 2).

JP 2000-345682 A JP 2005-105701 A

  As described above, it is considered that the construction method of the building outer wall by jointing joints requires adjustment of the width dimension of the outer wall material at the construction site and the necessity of jointing processing, as shown in Patent Document 2. This requires special cutting tools and machining operations. For this reason, it can be said that it is desirable to be able to join without generating the jointing of the outer wall material at the construction site. That is, a bonding method having excellent workability is desired.

  On the other hand, if the cutting process is simply to reduce the width of the outer wall material, and there is no need for step processing such as jointing, the temporary work of the outer wall material at the construction site will occur. Even so, it can be considered that the work load is small because the work load can be easily performed in a short time as compared with the case of jointing.

  However, if there is no step processing such as a jointed portion on the vertical end surface of the cut outer wall material, it is a new one to ensure waterproofness at the joint between the jointed portions of the adjacent outer wall materials. Structure is required. This is for joining the vertical end face without step processing and the jointed portion.

  If it is possible to realize a joining form that joins the vertical end face without joints with the stepped portion while ensuring waterproofness at the joint, cut one of the outer wall materials in the laterally adjacent outer wall material. By simply processing, adjustment work can be easily performed at the construction site.

  In addition, it is presupposed that the jointing portion to be joined to the vertical end surface without step processing is a backing portion formed by cutting out the back surface side of the outer wall material. This is because if the front facing portion is formed by cutting out the surface side of the outer wall material, another member for hiding the facing portion is required.

  On the other hand, regarding the adjustment of the height dimension of the outer wall material, the outer wall material is generally stacked from the lower row toward the upper row, and the upper side of the outer wall material arranged in the uppermost row is cut and removed. Thus, the height dimension is adjusted. Since the end face newly formed by cutting is arranged near the eaves and is not joined to other exterior materials, no special processing is required.

  Because of this, for the upper and lower sides of the outer wall material, it is necessary to carry out joint pricking in advance in a factory or the like as in the past, and to carry out peg jointing between the upper and lower outer wall materials. No particular problem will occur.

  The present invention has been made in view of the above problems. In other words, it provides a new construction method that replaces the construction method of the outer wall material using four-sided jointing, and in joining the vertical end surface and the jointing part without step processing of the outer wall material adjacent in the lateral direction, It provides a new technology that can ensure waterproofness.

This is a joining tool for joining a corner material with a substantially L-shaped cross section, a back-end scraped portion of one outer wall material adjacent in the lateral direction, and a vertical end surface without step processing of the other outer wall material. And a method of constructing the outer wall of the building using a joining tool having a vertical groove portion for draining water entering from the joint portion of both outer wall materials. Then, the dimension of the width direction is adjusted for at least one of the outer wall materials arranged in a plurality, and the vertical sides on both sides of the right side and the left side are made vertical end surfaces without step processing, and one side without step processing.

  With the above configuration, as shown in FIG. 6, even when water penetrates through the sealing surface 16a or the sealing surface 16b and toward the rear side of the protruding corner material 20B or the outer wall material 1C, It is possible to drain the infiltrated water downward from the longitudinal groove portions 17a and 17b. In this way, it is possible to achieve the second stage water stop by the vertical groove portions 17a and 17b.

  Further, as shown in FIG. 6, the sealing portions 16 c and 16 d can be formed between the water-stopping portions 68 a and 69 a and the back surfaces 20 b and 1 b, respectively.

  As a result, as shown in FIG. 6, even when water enters the longitudinal groove portions 17a and 17b, the seal portions 16c and 16d allow a wider range of water on the rear corner portions 20B and the back surfaces 20b and 1b of the outer wall material 1C. Intrusion can be prevented. In this way, the third-stage water stopping by the seal portions 16c and 16d can be realized. In addition, it is good also as a structure by which packing material which consists of rubber | gum, resin, etc. is provided in each water stop part 68a * 69a and packing material is interposed between each water stop part 68a * 69a and back surface 20b * 1b. In addition, it is also conceivable that the water stop portions 68a and 69a are not in contact with the back surfaces 20b and 1b and the seal portions 16c and 16d are not formed.

  Further, as shown in FIG. 6, the distance W1 from the first fixed plate portion 61 to the water stop portion 68a and the distance W2 from the second fixed plate portion 64 to the water stop portion 69a in the bonding accessory 6 are as follows. These are formed substantially the same as the depth width W3 of the ventilation space 15. That is, the depth dimension (distance W1 · W2) in the interior / exterior direction of the portion between the protruding corner material 20B / outer wall material 1C and the waterproof sheet 5 in the joining accessory 6 is the same as that of the protruding corner material 20B / outer wall material 1C. The depth dimension (distance W3) in the indoor / outdoor direction of the ventilation space 15 formed between the waterproof sheets 5 is set to be substantially the same. Thereby, in the construction method in which the ventilation space 15 is formed between the corner member 20B / outer wall material 1C and the waterproof sheet 5, it is possible to use the joining accessory 6 without using other spacer members. It becomes.

  Further, as shown in FIG. 6, the first vertical plate portion 62 of the joining accessory 6 is arranged to face the indoor / outdoor direction end surface 24 u of the back-end scraped portion 24 a of the protruding corner material 20 </ b> B. Further, the third vertical plate portion 67 of the joining accessory 6 is arranged to face the vertical end surface 1n of the outer wall material 1C. In this way, the portion (first vertical plate portion) where the joining accessory 6 faces the indoor / outward direction end surface 24u of the back-end scraped portion 24a of the corner corner material 20B and the vertical end surface 1n of the outer wall material 1C. 62, and a third vertical plate portion 67).

  As a result, as shown in FIG. 6, if a situation occurs in which the corner corner material 20 </ b> B and the outer wall material 1 </ b> C are displaced in the lateral direction, the first vertical plate portion 62 and the third vertical plate portion 67. Thus, it is possible to regulate the lateral displacement of the protruding corner material 20B and the outer wall material 1C. This effect is obtained when, for example, the fixing bracket for fixing the protruding corner material 20B / outer wall material 1C to the housing side does not have a function of preventing the horizontal shifting, the lateral shifting of the protruding corner material 20B / outer wall material 1C. This method is particularly effective in a construction method that does not prevent this.

  Further, as shown in FIG. 5, the joining accessory 6 described above can be used also in joining the corner corner material 20B and the outer wall material 1X. In this case, since the joining edge portion 23a of the protruding corner material 20B and the vertical end surface 14a of the outer wall material 1X are not joined to each other, the joining accessory 6 arranged at this joining location is back-facing. It will be installed in a state where the upper and lower sides of the joining accessory 6 arranged at the joint portion between the jagged portion 14a and the outer wall material 1C are inverted.

  Further, as shown in FIG. 7, the joining accessory 6 having the configuration of the second embodiment is configured such that the back plated portion 13 a of the outer wall material 1 </ b> B at the vertical joint portion M <b> 1 adjacent to the square plate-like outer wall materials 1 </ b> B and 1 </ b> C. And it is applicable also when joining the vertical end surface 14a without the level | step difference process of 1 C of outer wall materials.

  The configuration of the present invention can be widely applied to a joining structure in which plate-like outer wall materials such as ceramic siding, ceramic siding, metal siding, and ALC plates are joined.
