Description

  The present invention relates to a building board construction member, a construction structure of a building board using the same, and a construction board construction method.

  Patent Document 1 discloses a construction structure of a conventional building board. The construction structure of a building board described in Patent Document 1 includes a wall material as a building board, and a plurality of wall materials are constructed in an armor shape. Here, the armored construction structure is that a plurality of building boards are arranged next to each other in the vertical direction, and a part of the upper building board of these building boards is overlapped from the front side of the lower building board. This is the structure that was constructed.

  By the way, in general, in order to attach the building board to the base in the form of armor, after fixing the lower building board to the base, arrange the upper building board so that part of it overlaps the lower building board on the front side While maintaining this state, a fixing tool such as a nail is struck on the upper building board. At this time, in order to hit the fixing tool on the upper building board, it is necessary to press the upper building board against the base with a hand or an arm so as not to deviate from the arranged position.

  However, when the size of the building board is large, it may be difficult to maintain the position because the weight increases. In this case, it is difficult for one person to work, and even if one person can work, for example, the wall material is tilted during the work, and the building board is fixed while tilted. Construction failure can occur.

  On the other hand, the armor-like construction structure of Patent Document 1 fixes a support member having an inverted L-shaped cross section to the back surface of the upper wall member with an adhesive or the like. When the upper wall material is attached and constructed, the support member is temporarily fixed by being hooked on the upper end surface of the lower wall material, and in this state, a fixing tool is applied to the upper wall material to perform the main fixing.

  As a result, the load on the upper wall material can be supported by the lower wall material, which not only facilitates construction, but also allows the upper wall material to be stably held at a position determined by design. Therefore, it becomes easy to work alone.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the following embodiment, an example in which the building board construction member according to the present invention is applied to a member used for construction of an outer wall board will be described.

Embodiment 1
As shown in FIG. 1, the outer wall structure of the present embodiment is a structure in which an outer wall plate 2 as a building board is attached to a base in an armor shape. In the armored outer wall structure, a plurality of outer wall plates 2 are arranged so as to be aligned at least in the vertical direction. Hereinafter, the lower outer wall plate 2 of the upper and lower adjacent outer wall plates 2 is referred to as a lower building board 21, and the upper outer wall plate 2 is referred to as an upper building board 22. In addition, as shown in FIG. 1, the lower level building board 21 of this embodiment is arranged in multiple numbers by the left-right direction in the same height position. Further, the upper building board 22 is also arranged in parallel in the left-right direction at the same height position.

  The foundation is a portion that becomes the foundation of the building board in the building, and is constituted by the wall foundation 1 that becomes the foundation of the outer wall board 2 in the present embodiment. The wall foundation 1 of the present embodiment includes a plurality of vertical trunk edges 11 and a wooden board 12 attached to a surface on the outdoor side of the plurality of vertical trunk edges 11. The plurality of vertical body edges 11 are attached to, for example, a structural face material fixed to a plurality of intermediate pillars (not shown) via a moisture permeable waterproof sheet. The wooden board 12 is, for example, plywood, and the surface on the outdoor side is substantially parallel to the vertical surface. A plurality of outer wall plates 2 are attached to the surface of the wooden board 12 on the outdoor side.

  Each outer wall plate 2 is configured by a plate body that is formed in a substantially rectangular shape when viewed from the front, and has a longitudinal direction parallel to the left-right direction (for example, formed with a vertical width of 414 mm × a horizontal length of 910 mm). The upper end surface of the outer wall plate 2 is inclined so as to be positioned downward as it approaches the side end surface at both ends in the left-right direction.

  Each outer wall plate 2 has a plurality of mounting holes 23. The plurality of mounting holes 23 are formed at predetermined intervals in the left-right direction at a substantially central portion in the up-down direction of the outer wall plate 2. The plurality of mounting holes 23 are arranged on a virtual straight line parallel to the lower side of the outer wall plate 2, that is, arranged in parallel to the direction along the lower side of the outer wall plate 2. Each mounting hole 23 is configured by a through-hole penetrating the outer wall plate 2.

  Note that the attachment hole 23 may be a semi-through hole. The semi-through hole is a hole that includes a through hole (not shown) that penetrates the outer wall plate 2 and a thin-walled portion (not shown) that covers the through hole, and is not penetrated immediately after manufacture. When a semi-through hole is used as the attachment hole 23, since it does not penetrate in the state before the fixture 5 is inserted into the attachment hole 23, it is possible to prevent water from entering the unused attachment hole 23.

  In the outer wall structure of the present embodiment, a plurality of outer wall plates 2 are arranged side by side in the left-right direction and also arranged in the up-down direction. The outer wall plates 2 adjacent to each other in the vertical direction are displaced in the left-right direction and are arranged in a so-called staggered pattern. In the present embodiment, the outer wall plates 2 adjacent to each other in the vertical direction are deviated by a half of the length of the outer wall plate 2 in the left-right direction. Each outer wall plate 2 is provided with a mark for alignment, and is devised so that the arrangement position of the outer wall plate 2 does not shift during construction.

  The upper building board 22 of the present embodiment is temporarily held by the building board construction member 3 with respect to the lower building board 21 and then fixed (mainly fixed) by the fixture 5. As shown in FIG. 2A, the building board construction member 3 is inserted into the mounting hole 23 of the upper building board 22 and used. The building board construction member 3 includes an insertion part 31 and a front side contact part 36.

  The insertion portion 31 is a portion that is inserted from the front side (the outdoor side in the present embodiment) toward the back side (the indoor side in the present embodiment) with respect to the mounting hole 23 of the upper building board 22. The insertion part 31 extends in the indoor / outdoor direction. The outer diameter of the insertion part 31 is formed slightly smaller than the inner diameter of the mounting hole 23. Further, a through hole 32 formed along the central axis of the insertion part 31 is provided inside the insertion part 31. The through-hole 32 penetrates the insertion portion 31 in the indoor and outdoor directions, and is configured such that a fixing tool 5 such as a nail can be inserted. Here, the insertion portion 31 is configured by an in-hole accommodation portion 33 disposed inside the attachment hole 23 in a state of being inserted into the attachment hole 23 and a support portion 34 extending from the in-hole accommodation portion 33. Yes.

  The in-hole accommodating portion 33 is a region that fits in the attachment hole 23 in the insertion portion 31. The indoor / outdoor length of the in-hole accommodating portion 33 is formed to be approximately the same as the thickness of the outer wall plate 2. The in-hole accommodating portion 33 of the present embodiment is configured by a region between a flange-shaped front-side contact portion 36 and a back-side contact portion 35 formed on the outer peripheral surface of the support portion 34.

  The back-side contact portion 35 is configured by a protrusion that protrudes in a direction orthogonal to the length direction of the insertion portion 31. The back side abutting portion 35 is separated from the front side abutting portion 36 by substantially the same dimension as the thickness dimension of the outer wall plate 2. When the insertion portion 31 is inserted into the mounting hole 23, the back side contact portion 35 faces the indoor side surface of the outer wall plate 2. The back side abutting portion 35 includes a facing surface 351 that faces the indoor side surface of the outer wall plate 2, and a guide surface 352 that extends toward the indoor side from the protruding tip end of the back side abutting portion 35 on the facing surface 351. And.

  The facing surface 351 is configured by a vertical surface that is substantially parallel to a surface orthogonal to the central axis of the insertion portion 31. Since the outer wall plate 2 enters between the facing surface 351 and the indoor side surface of the front side contact portion 36, the outer wall plate 2 can be sandwiched between the back side contact portion 35 and the front side contact portion 36. Movement of the construction member 3 in the indoor / outdoor direction is restricted.

  The guide surface 352 is inclined so as to be closer to the central axis of the insertion portion 31 toward the indoor side. By providing the guide surface 352 on the back side abutting portion 35, it can be smoothly inserted when the insertion portion 31 is inserted into the mounting hole 23, and the back side abutting portion 35 is caught on the inner peripheral edge of the mounting hole 23. Can be suppressed.

  The support portion 34 is a portion that extends from the indoor side end of the hole accommodating portion 33 to the indoor side, and is a region that protrudes from the outer wall plate 2 at the insertion portion 31. Since the support part 34 protrudes from the surface on the indoor side of the outer wall board 2, as shown in FIG. 2B, when mounting the upper building board 22, the support part 34 is placed on the upper end surface of the lower building board 21, The load of the upper building board 22 can be supported. The dimension of the support portion 34 in the indoor / outdoor direction is substantially the same as the thickness of the outer wall plate 2.

  The insertion part 31 has a plurality of slits 39. Each slit 39 penetrates the peripheral wall portion of the insertion portion 31 in the radial direction, and extends along the central axis direction at least from the indoor side end portion of the in-hole housing portion 33 to the indoor side end portion of the support portion 34. Is formed. The insertion part 31 of the present embodiment is formed over the entire length of the insertion part 31. By forming the plurality of slits 39, the tip (projecting tip) of the back-side contact portion 35 is configured to be elastically displaceable in a direction perpendicular to the central axis direction (that is, the insertion direction).

  The building board construction member 3 of the present embodiment is made of a material having rigidity such as synthetic resin or metal. In particular, the insertion portion 31 is set to a thickness that allows the insertion portion 31 to be elastically deformed while ensuring a certain rigidity so that the protruding tip of the back-side contact portion 35 can be displaced.

  The front contact portion 36 is formed to have a larger diameter than the outer diameter of the insertion portion 31. The front contact portion 36 faces the outdoor side surface of the outer wall plate 2. The through hole 32 formed in the insertion part 31 passes through the center of the front contact part 36.

  The building board construction member 3 is inserted into the mounting hole 23 of the outer wall board 2 from the outdoor side. Then, the tip of the support portion 34 enters the mounting hole 23, and then the guide surface 352 comes into contact with the inner peripheral edge on the outdoor side of the mounting hole 23. When the insertion of the building board construction member 3 is further continued, the guide surface 352 is pressed in the central axis direction by the inner peripheral edge of the mounting hole 23, and the insertion portion 31 is elastically reduced in diameter. Then, when the building board construction member 3 is pushed in until the front side abutting portion 36 abuts on the outdoor side surface of the outer wall plate 2, the deformation of the insertion portion 31 is restored, and the opposing surface 351 is located on the indoor side of the outer wall plate 2. Opposite the surface. As a result, the building board construction member 3 is mounted in the mounting hole 23 of the outer wall board 2.

  The building board construction member 3 attached to the wall base 1 abuts the wall base 1 at the tip. For this reason, when driving the fixing tool 5 at the time of construction, the building board construction member 3 functions as a spacer even when the fixing tool 5 is driven strongly, so that the outer wall board 2 can be prevented from cracking.

  Next, the construction method of the outer wall of this embodiment is demonstrated based on FIG.

  The installer attaches the starter 4 to the lower end portion of the wall base 1 (FIG. 3A), and fixes the lower building board 21 so as to overlap the starter 4 (FIGS. 3B to 3C). At this time, the building board construction member 3 is attached to each of the plurality of mounting holes 23 of the lower building board 21, and the support portion 34 of the building board construction member 3 is placed on the upper end surface of the starter 4 and temporarily held. In this state, the fixture 5 is driven to fix the lower building board 21 to the wall base 1.

  Next, the installer attaches the upper building board 22 (FIG. 3D). The installer attaches the building board construction member 3 to each of the plurality of mounting holes 23 of the upper building board 22 and places the support portion 34 of the building board construction member 3 on the upper end surface of the starter 4 to temporarily hold it. In this state, the fixture 5 is driven to fix the lower building board 21 to the wall foundation 1.

  Then, another outer wall plate 2 is attached in the same manner above the fixed upper building board 22, and this is repeated sequentially (that is, the upper building board 22 is attached above the lower building board 21). The outer wall can be formed.
