Description

  The present invention relates to the construction of vertical joints that can be made by joining together the longitudinal ends of drywall materials used in construction and construction. More specifically, the present invention relates to a vertical joint structure in which the waterproofness and the workability of the connection portion are improved.

  In general, a wall is formed by using a dry wall material having a sandwich structure in which a metal plate is used as a surface material, a synthetic resin foam is used as a core material, and a sheet material is used as a backing material. When the body is formed, a vertical joint is formed by butt-welding in the longitudinal direction of the dry wall material, and the vertical joint is simply butted, a caulking material is implanted, an H-shaped joiner is used, or a floor board is used. There is a method of forming a vertical joint by fitting the two members of the cover and the cosmetic cap. (See, for example, Patent Document 1).

  However, Patent Document 1 relates to a vertical jointer and corresponds to a vertical joint portion of a dry wall material having a ridge shape, but the workability, positioning when inserting the upper end into the connection portion of the dry wall material, There was a problem with the

  In the vertical joint structure in which the present invention covers the joint portion of the end of the dry wall material with a decorative cap in order to solve such a defect, the decorative cap has a substantially vertical flat decorative surface and an upper end of the decorative surface. In addition, a projecting piece projecting the upper end of the decorative surface part further upward, and a projecting part projecting outward by inserting both end parts of the projecting piece into the indoor side, and an inserting piece formed on both ends of the projecting part The present invention provides a vertical joint structure in which a joint portion of a dry wall material is covered with a decorative cap in which an air gap is formed by a step between a convex portion and an insertion piece.

  According to the vertical joint structure according to the present invention, the insertion pieces recessed toward the indoor side are formed at the left and right end portions of the protruding pieces at the upper end of the decorative surface portion of the cosmetic cap, and the insertion pieces form the air gap. The convex part of the piece serves as a mark, and the insertion of the projecting piece into the locking groove of the dry wall material is easy. (2) Since the projection is formed between the left and right drywalls, the insertion position of the projecting piece into the locking groove of the drywall is clear. (3) It can be easily inserted even if the gap of the locking groove of the dry wall material is very small. There are features and effects such as

  Hereinafter, typical embodiments of the vertical joint structure according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a cross-sectional view showing the construction of a vertical joint joiner A consisting of a floor board B and a decorative cap C, and FIG. 2 is a perspective view showing the construction of a vertical joint joiner A consisting of a floor board B and a decorative cap C FIGS. 3 (a) and 3 (b) are cross-sectional views showing a decorative cap C and a floor plate B used for the vertical joint structure according to the present invention, and FIG. 4 is a cross-sectional view showing one embodiment of a dry wall material D. FIG. 5 is a cross-sectional view showing the construction of the dry wall material D, where M is a joint, T is a vertical joint, Y is a horizontal joint, α is a wall base, and β is a fixture.

  More specifically, the vertical joint joiner A consisting of the floor plate B and the decorative cap C is a thin metal plate material such as iron, aluminum, copper, stainless steel, titanium, aluminum-zinc alloy plated steel plate, galvan steel plate, enameled steel plate, clad A type of steel plate, laminated steel plate (PVC steel plate etc.), sandwich steel steel plate (vibration damping steel plate etc.), synthetic resin plate material, eg vinyl chloride resin, polycarbonate resin etc. (of course including color plates coated with various color tones) It is formed into various shapes by roll forming, press forming or the like.

  The floor plate B is a long plate material, and is formed of the horizontal portion 1 and the fitting portion 4 as shown in FIG. 3 (a). More specifically, the horizontal portion 1 is formed of a horizontal fixed piece 2 and a tongue 3 in which the tip of the fixed piece 2 is bent in a spiral shape. Further, the fitting portion 4 is formed by bending two guide pieces 5 formed by bending the substantially central part of the horizontal part 1 upward, and the tips of both guide pieces 5 inward and bending the tips inward. The fitting groove 6 having a substantially U-shaped cross section is formed, and is formed from the fitting claw 7 projecting into the fitting groove 6. The fitting portion 4 is a portion for engaging an engaging portion 9 of a cosmetic cap C described later.

  The decorative cap C is determined by the decorative surface and the cross-sectional shape of the dry wall material D. When the dry wall material D as shown in FIG. 4 is used to form a wall, it is shown in FIGS. It becomes such a makeup cap C. 6 and 7 are cross-sectional views showing how to connect the cosmetic cap C. As shown in FIG.

  More specifically, as shown in FIG. 8 to FIG. 10, the cosmetic cap C has a narrow width and a cosmetic surface portion 8 conforming to the cross-sectional shape of the dry wall material D, and an engagement projecting longitudinally in the center of the rear surface of the cosmetic surface portion 8 It forms from the part 9, and the decorative surface part 8 is a part which coat | covers the edge part of the dry-wall material D, and improves design property and waterproofness, as shown to FIG. 1, FIG.

  The engaging portion 9 is composed of a rising portion 10 bent at a position capable of protruding to the center of the back surface of the decorative surface portion 8 by 90 °, and an engaging piece 11 protruding outward in the vicinity of the tip of the rising portion 10 The piece 11 is engaged with the fitting claw 7 of the floor plate B to fix the cosmetic cap C to the wall base α.

  The upper portion 12 forms a projecting piece 12a projecting the upper end of the decorative surface portion 8 further upward, and an insertion piece 14 of the projecting portion 13 and the projecting portion 13 at both ends by recessing both ends of the projecting piece 12a to the indoor side. Thus, the air gap 15 formed by the convex portion 13 and the insertion piece 14 is formed.

  The lower portion 16 is formed by a cover piece 17 which bends the lowermost end of the decorative surface portion 8 to the indoor side and covers the lower end portion of the dry wall material D.

  The insertion piece 14 is inserted into the locking groove D4 of the dry wall material D as shown in FIG. 6, whereby the upper end of the decorative cap C is fixed, and the space 15 is a space in the locking groove D4. By forming K, the capillary phenomenon in the locking groove D4 is prevented, and the waterproofness is enhanced.

  The convex portion 13 is formed to be equal to or narrower than the width W of the vertical joint portion T so as to prevent the lateral displacement of the cosmetic cap C at the vertical joint portion T.

  As shown in FIG. 4, the dry wall material D is a dry wall material D of male and female fitting structure in which the locking piece D3 is formed in the male connection portion D1 and the locking groove D4 is formed in the female connection portion D2. It is molded from a system siding material, a ceramic siding material, a ceramic, etc.

  What has been described above is merely an example of the vertical joint structure according to the present invention, and can be formed as shown in FIGS. 11 (a) and (b) to 13 (a) and (b).

  FIGS. 11 (a) and 11 (b) show a cosmetic cap C which can be used at the corner portion or the corner portion.

  12, 13 (a) and 13 (b) show a decorative cap C for the output corner which can be formed at the output corner portion, and without using the floor plate B, the locking groove of the dry wall material D at the lower end portion. The hooking piece 18 is inserted into D4, and the upper end is fixed to the wall base α by a fixing tool β such as a nail by eyeing from the fixing hole 19 to the fixing hole 20.
