Description

  The present invention relates to a corner wall material fastener that can be suitably used for new construction and renovation of a wooden building, a steel building, a reinforced concrete (RC) building, and the like, and a heat insulating wall using the same.

  The outer insulation method is a method in which a heat insulating wall (heat insulating layer) is provided outside the structural frame. Generally, after temporarily attaching the heat insulating material to the pillars and the studs, the body edge is fastened from the surface side of the heat insulating material. After attaching (the body edge and the heat insulating material are fastened simultaneously), after that, exterior materials such as siding are fastened to the surface of the body edge. However, in this general construction method, when foam-type heat insulating material is used, it is necessary to temporarily fix the heat insulating material to the pillars and the intermediate pillars with nails, screws, etc., and then press and hold it from the top with the trunk edge. There was a problem that a lot of work was required. In addition, the construction of the heat insulating material and the construction of the trunk edge are necessary before the construction of the exterior material, and this also has a problem that the labor of construction is large. Furthermore, since the heat insulating performance of the heat insulating wall is determined only by the heat insulating performance of the heat insulating material, if a large heat insulating effect is to be obtained, a heat insulating material with a large thickness must be used, leading to an increase in cost. .

  Then, in order to solve these problems, the heat insulation wall using the wall material fastener is proposed (refer patent document 1). An example of the wall material fastener A described in Patent Document 1 is shown in FIG. In this wall material fastener A, a support plate 11 for supporting the heat insulating material 3 and the exterior material 4 is extended from the surface of the substrate 10 fixed to the surface of the wall base 2, and on the front and back surfaces of the support plate 11 A locking piece 12 for positioning the heat insulating material 3 applied to the surface of the substrate 10 is erected, and the exterior is separated from the positioning locking piece 12 by a necessary space width S on the tip side of the support plate 11. A pair of positioning locking pieces 13, 14 that are engaged with the ends of the material 4 are erected on the support plate 11.

  And when constructing | assembling a heat insulation wall using the said wall material fastener A, it carries out as follows. First, as shown in FIG. 15 (b), a fastening tool 7 such as a nail or a screw is driven and fixed to a substrate 10 disposed on the surface of the wall base 2 such as a column or a girder. Then, a heat insulating material 3 made of foamed resin or the like is installed between the substrate 10 and the locking piece 12, and then an exterior material 4 such as a fiber reinforced cement board is installed on the locking pieces 13 and 14. The exterior material 4 is formed with joint steps that are fitted to each other at the upper and lower edges, the locking piece 13 is in contact with the back surface of the exterior material 4, and the locking piece 14 is a fitting groove formed in the exterior material 4. Is engaged. After installing and positioning the lower ends of the heat insulating material 3 and the exterior material 4 in this way, a wall material fastener A different from the above is applied to these upper end portions, and the substrate 10 is attached to the wall base 2 with nails, screws, or the like. Fix with the fasteners 7. Then, the heat insulating material 3 and the exterior material 4 different from the above are placed on the wall material fastener A disposed at the upper end portions of the heat insulating material 3 and the exterior material 4 in the same manner as described above. In this way, by sequentially attaching the wall material fastener A, the heat insulating material 3 and the exterior material 4 to the wall base 2, the heat insulating wall can be formed outside the wall base 2.

However, when the above-described wall material fastener A is used, there is a problem in that the width of the exterior material 4 protruding from the wall base 2 at the corner is large and the construction is difficult.

The heat insulating material 3 is inclined in the same direction as the inclination of the inclined portion 72 which is an inclination means with the fulcrum portion 26 as a fulcrum. Therefore, when the heat insulating material 3 is supported by the wall material fastener A, the heat insulating material 3 is naturally inclined toward the wall base 2 and is put on the surface of the wall base 2. Thereby, the new heat insulating material 3 is attached to the upper side of the heat insulating material 3 and the heat insulating material 3 does not fall forward until the upper portion of the heat insulating material 3 is fixed to the wall base 2 with the wall material fixing device A. Thus, it is not necessary for the operator to support it by hand or to temporarily fix the heat insulating material 3 to the wall base 2 with an adhesive or an adhesive tape.

  Next, the airtight tape 66 is stuck so as to close a gap formed between the heat insulating materials 3 and 3 adjacent to each other with the heat insulating material support piece 21 interposed therebetween. This airtight tape 66 is a tape material formed by providing an adhesive layer on a non-breathable base material, and by adhering the airtight tape 66 over the heat insulating materials 3 and 3 adjacent to each other, a gap is formed. It is blocked to prevent a decrease in heat insulation. When the airtight tape 66 is stuck, the upper end of the exterior material 4 is locked to the downward holding piece 46 of the exterior material holding portion 22 provided below the heat insulating material support piece 21. In addition, the upper end of the exterior material 4 is positioned below the gap. Therefore, when the gap is closed with the airtight tape 66, the upper end of the exterior material 4 does not get in the way, and the airtight tape 66 can be easily attached.

  Next, another exterior material 4 is supported on the wall material fastener A. That is, by inserting the groove 61 at the lower end of the new exterior material 4 into the upward holding piece 45 of the exterior material holding part 22 of the wall material fastener A attached to the wall base 2, the exterior material 4 is attached to the wall material fastener. A is held and supported. Here, the lower exterior material 4 and the exterior material holding part 22 of the wall material fastener A are covered with the lower end of the upper exterior material 4.

  Thereafter, another wall material fastener A is attached to the upper side of the heat insulating material 3 and the exterior material 4 supported by the wall material fastener A. This wall material fastener A can be attached by the same method as described above. And the predetermined number of wall material fastener A, the heat insulating material 3, and the exterior material 4 are attached in order.

  FIG. 5 shows the vicinity of the upper end of the heat insulating wall, and a wooden trunk edge 80 is attached to the wall base 2 above the uppermost heat insulating material 3. A spacer 69 is provided between the uppermost exterior material 4 and the heat insulating material 3 and between the uppermost exterior material 4 and the wooden trunk edge 80, and the spacer 69 extends from the surface (outdoor surface) of the exterior material 4. The fastener 7 is screwed into the wooden trunk edge 80 so as to pass through the upper part of the exterior material 4. Further, a parting edge 71 is provided between the uppermost exterior material 4 and the eaves ceiling 70. Further, a ventilation layer 81 having a thickness dimension of the ventilation layer forming means 30 is formed between the exterior material 4 and the heat insulating material 3. The ventilation layer 81 can prevent condensation on the back side of the exterior material 4.

  In the above-described wall material fastener A, the rear surfaces of the upper locking portion 27 and the lower locking portion 28 (surfaces on the side of the heat insulating material support piece 21 when the wall material fastener A is attached to the wall base 2 Projections 25 are provided on the surface facing the base 2 side. Further, at a position slightly below the protrusion 25 of the upper locking portion 27, the front surface of the fixing piece 20 (the surface on the side of the heat insulating material support piece 21, when the wall material fastener A is attached to the wall base 2. Further, a fulcrum portion 26 is formed on the surface facing the opposite side of the wall base 2. The fulcrum portion 26 is formed by a bent portion at a boundary portion between the bent portion 31 and the inclined portion 72.

  As described above, when the lower end of the heat insulating material 3 is inserted between the upper locking portion 27 and the fixed piece 20, the lower portion of the heat insulating material 3 is pressed against the wall base 2 by the protrusion 25 and the heat insulating material. 3 inclines in the same direction as the inclination of the inclined part 72 with the fulcrum part 26 as a fulcrum. Therefore, when the heat insulating material 3 is supported by the wall material fastener A, the heat insulating material 3 is naturally inclined toward the wall base 2 and is put on the surface of the wall base 2. Therefore, until the new wall material fastener A is attached to the upper side of the heat insulating material 3, the heat insulating material 3 can be pressed and temporarily fixed to the wall base 2 side by the protrusion 25 without using an adhesive or an adhesive tape. The heat insulating material 3 and the exterior material 4 can be easily constructed. Note that the protrusion 25 and the fulcrum portion 26 are not necessarily provided, and may be provided as necessary.

  In FIG. 6, the junction part of the heat insulating materials 3 and 3 and the outer wall materials 4 and 4 which adjoin a horizontal direction is shown. A gap 34 may be formed between the side end surfaces of the heat insulating materials 3 and 3 adjacent in the lateral direction. Therefore, a long airtight tape 66 is attached along the gap 34 so as to cover the gap 34. This airtight tape 66 is a tape material formed by providing an adhesive layer on a non-breathable base material, and by sticking the airtight tape 66 on the outdoor surface across the heat insulating materials 3 and 3 adjacent to the left and right. The gap 34 is closed to prevent a decrease in heat insulation. In addition, the airtight tape 66 is stuck between the upper and lower wall material fasteners A. Further, a waterproof material 74 composed of the backup material 35 and the sealing 36 can be filled between the outer wall materials 4 and 4 adjacent in the lateral direction in order to ensure waterproofness. With this waterproof material 74, the airtight tape 66 can be pressed from the surface side. In the above case, the backup material 35 of the waterproof material 74 is pressed against the surface (outdoor side surface) of the hermetic tape 66, and even if the adhesive force of the hermetic tape 66 weakens due to a change with time or the like, the waterproof material 74 is waterproof. The material 74 can be pressed so as not to be peeled off from the heat insulating material 3, and a decrease in heat insulating property can be prevented. The waterproof material 74 is composed of the backup material 35 and the sealing 36. As the backup material 35, a resin foam such as foamed polyethylene such as a square bar or a round bar can be used. The sealing 36 is formed using a silicon-based sealing, a polysulfide-based sealing material, an acrylic urethane-based sealing material, a polyurethane-based sealing material, an acrylic-based sealing material, a styrene-butadiene rubber-based sealing material, a butyl rubber-based sealing material, or the like. Can do.

  In this manner, a heat insulating wall composed of the heat insulating material 3, the exterior material 4, and the wall material fastener A can be formed.

  Although the case where the heat insulation wall is formed on the outdoor side of the wall of the existing building has been described above, the outer wall of the newly built building can be formed as the heat insulation wall using the wall material fastener A. In this case, the wall foundation 2 is formed of a base 38 provided on the foundation 37 and a structural material 39 such as a column or a stud attached to the base 38. A moisture permeable waterproof sheet 47 is attached to the entire surface (outdoor side surface) of the wall base 2. First, as shown in FIG. 7, a foundation drainer 50 and a starter fitting 51 are attached to the surface of the foundation 38 below the wall base 2. The base drainer 50 and the starter fitting 51 are formed in the same manner as described above, and the surface of the wall base 2 is inserted by inserting the fastener 7 into the mounting piece 59 and the upper part of the base drainer 50 and screwing into the base 38. A base drainer 50 and a starter fitting 51 are attached to the lower part of the (outside side).

  Next, the heat insulating material 3 and the exterior material 4 are supported by the starter fitting 51 in the same manner as described above. Next, the wall material fastener A is attached to the upper side of the heat insulating material 3 and the exterior material 4 arranged on the outdoor side of the wall base 2 with the starter fitting 51. The wall material fastener A can be attached in the same manner as described above, and the upper end portion of the heat insulating material 3 supported by the starter fitting 51 is placed between the sandwiching piece 43 and the lower locking piece 28 of the wall material fastener A. And the downward holding piece 46 of the exterior material holding part 22 is engaged with the engaging protrusion 62 at the upper end of the exterior material 4 supported by the starter metal 51, and then the fixing part 40 of the fixed piece 20 is secured. It is fixed to the structural material 39 of the wall base 2 by the fastening tool 7. Thereafter, as shown in FIG. 8, a predetermined number of wall material fasteners A, heat insulating material 3 and exterior material 4 are sequentially attached in the same manner as described above.

  FIG. 9 shows the vicinity of the upper end of the heat insulating wall, and a wooden trunk edge 80 is attached to the structural member 39 of the wall base 2 by a fastener 7 on the upper side of the uppermost heat insulating material 3. This structure is the same as that in the case where the existing wall is the wall base 2. In FIG. 10, the junction part of the heat insulating materials 3 and 3 and the outer wall materials 4 and 4 which adjoin a horizontal direction is shown. This structure is the same as that in the case where the existing wall is the wall base 2 except that the wall base 2 is formed of the base 38 and the structural material 39. The wall material fastener A can be fixed to the auxiliary member 39 a provided on the side surface of the structural material 39 with the fastening device 7. FIG. 11 shows a case in which the wall material fastener A is provided at a substantially central portion in the lateral direction of the heat insulating material 3 and the exterior material 4. In this case, the wall material fastener A is fixed to the structural material 39 such as a stud with the fastener 7.

  FIG. 12 shows the structure of the corner of the heat insulating wall. As shown in FIG. 1 (a), the wall material fastener B for the corner used here has the same cross-sectional shape as the wall material fastener A, but as shown in FIGS. 1 (b) and 1 (c). In a plan view, one side end portion is formed as a butt portion 90 formed to be inclined. The corner wall material fastener B of FIG. 1 (b) and the corner wall material fastener B of FIG. 1 (c) are formed in a line-symmetric shape in a plan view. The corner wall material fasteners B and B are used as a set for one corner. The corner wall material fastener B can be formed by obliquely cutting one side end of the wall material fastener A, but is not limited to this, and can be formed by various molding methods. it can.

  Of the pair of corner wall members B, B, one corner wall member B is attached to one outer surface constituting the corner of the wall base 2 and the other corner wall member. The fastener B is attached to the other outer surface constituting the corner of the wall base 2, and the wall material fasteners B and B for corners are fixed to the structural material 39 at the corner by the fastener 7. At this time, the abutting portions 90, 90 of the pair of corner wall fasteners B, B attached to the outer surfaces adjacent to the corners are in abutted state.

  Thereafter, the end portion of the heat insulating material 3 is attached to the corner wall material fastener B in the same manner as in the case of the wall material fastener A, but is supported by one corner wall material fastener B. The end surface 91 of the heat insulating material 3b supported by the other corner wall material fastener B is brought into contact with the end surface of the heat insulating material 3a, and the heat insulating material 3a is formed at a joint portion between the adjacent heat insulating materials 3a and 3b. An airtight tape 66 is stuck along the gap 34 on the surfaces of the heat insulating materials 3 a and 3 b so as to cover the gap 34. The airtight tape 66 can prevent the heat insulation performance from being impaired. Further, the end of the exterior material 4 is attached to the corner wall material fastener B in the same manner as the wall material fastener A, but a backup material is attached to the joint portion between the ends of the adjacent exterior materials 4 and 4. The waterproof material 74 which consists of 35 and the sealing 36 is filled.

  Further, since the projection 25 and the inclined portion 72 are formed as the tilting means in the corner wall material fastener B as in the case of the wall material fastener A described above, the gap between the upper locking portion 27 and the fixed piece 20 is formed. When the lower end of the heat insulating material 3 is inserted, the lower portion of the heat insulating material 3 is pressed to the wall base 2 side by the projection 25 that is a tilting means, and the heat insulating material 3 uses the fulcrum portion 26 as a fulcrum to support the inclined portion 72 that is the tilting means. It will tilt in the same direction as the tilt. Therefore, when the heat insulating material 3 is supported by the wall material fastener B for the corners, as shown in FIG. 13, the heat insulating material 3 is naturally inclined toward the wall base 2 and applied to the surface of the wall base 2. Thereby, an operator supports by hand or adhesives or adhesive tapes so that the heat insulating material 3 does not fall forward until the upper portion of the heat insulating material 3 is fixed to the wall base 2 with the wall material fastener A. Thus, it is not necessary to temporarily fix the heat insulating material 3 to the wall base 2, and the construction becomes easier.

  Further, even when the protruding width of the exterior material 4 from the wall base 2 is increased by aligning the position of the fixing hole 41 of the corner wall material fastener B with the position of the structural member 39 of the wall base 2, the wall base The exterior material 4 can be firmly fixed to 2. That is, by attaching the corner wall material fasteners B and B to the corner of the wall base 2 with the butted portions 90 and 90 of the corner wall material fasteners B and B butted together, The exterior material holding portion 22 can be disposed outside the top portion 93, and the exterior material 4 is firmly supported by the interior wall material fastener B even outside the top corner 93 and attached to the wall base 2. be able to.

  FIG. 14 shows the structure of the protruding corner of the heat insulating wall.

The fastener C is fixed to the structural member 39 at the projecting corner with the fastening tool 7 in a state where the diagonally cut sides are combined. Further, the end portion of the heat insulating material 3 is attached to the wall material fastener C for the corners in the same manner as the wall material fastener A, but the surface of the joint portion between the end portions of the adjacent heat insulating materials 3 and 3 is attached to the surface. An airtight tape 66 is attached in the vertical direction. In addition, an L-shaped corner outer wall member 42 in a plan view is attached to the outer corner wall member C as the exterior member 4. The cross-sectional shapes of the corner outer wall material 42 and the flat plate outer wall material 4 are the same, and the corner outer wall material 42 is attached to the corner wall material fastener C in the same manner as when the outer wall material 4 is attached to the wall material fastener A. Can be attached. Further, a waterproof portion 74 composed of a backup material 35 and a sealing 36 is filled in the joint portion of the end portion of the exterior material 4 adjacent to the corner outer wall material 42.

  In this way, a heat insulating wall composed of the heat insulating material 3, the exterior material 4, the wall material fastener A, the entrance wall material fastener B, the exit wall material fastener C, and the corner outer wall material 42 can be formed. .
