Description

[Technical field]

[0001] The present invention relates to a starter for use when installing exterior materials such as sandwich panels. [Background technology]

[0002] Generally, when installing exterior materials such as sandwich panels horizontally, a water strip and starter are installed on the furring strip, and then the exterior material is installed. Many starters have been invented to date, and many of them have been marketed that offer ease of installation and high aesthetics. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 11-223006 [Patent Document 2] JP 2018-44403 A Summary of the Invention [Problem to be solved by the invention]

[0004] Starters for exterior materials such as sandwich panels must be compatible with a wide variety of installation methods, including the fixing position, fastening method, the presence or absence of sealant, and the presence or absence of drainage pipes, depending on the location where they are installed. For example, starter fastening methods include top fastening, which fastens the upper side of the surface on which the exterior material is placed, and bottom fastening, which fastens the lower side of the surface on which the exterior material is placed. Top fastening allows the fasteners used to fasten the starter to be completely hidden by the subsequent installation of the exterior material, but the horizontal furring strips to be installed must be of a certain size. Therefore, bottom fastening may be used when the horizontal furring strips cannot be sufficiently large or when no gap is required between the bottom end of the exterior material and the drain. Patent Document 1 describes a roughly U-shaped starter that can be used regardless of whether it is top- or bottom-mounted, but unless a specially shaped drip edge is used, the starter and drip edge cannot be installed in contact with each other, and it is necessary to mark the installation position of the starter. In addition, the weight of the exterior material is concentrated on one surface, which may cause deformation.

[0005] Patent Document 2 describes a starter that can be used for top and bottom fastening by rotating the same member, but when used for bottom fastening, the distance between the surface on which the exterior material such as a sandwich panel is placed and the fixing part that is fixed using a fastener is too far, and there is a risk that more load than necessary will be applied to the fixing part 12a. Also, in order to apply a sealant between the drip edge and the starter, it was necessary to create a separate seal receiving part and fasten it to the starter, so it can be said that there is room for improvement in terms of workability as well. [Means for solving the problem]

[0006] Therefore, in the present invention, a fixing surface for attaching the starter to the furring strip is provided with multiple fixing parts, a mounting surface for placing an exterior material such as a sandwich panel, a protruding piece and a locking part are provided at the outdoor side end of the mounting surface, and a panel receiving part is provided on the indoor side of the mounting surface.Furthermore, a starter with a seal receiver is provided, in which a lower end is provided at one end of the fixing surface and a seal receiving part is provided with the lower end protruding to the outdoor side.

[0007] 5 and 6, when the product of the present invention is used with bottom fastening, the step of marking out the starter 1 with seal receiver can be omitted by abutting the lower end 9 against the indoor end of the inclined surface 42 of the drain 40. Furthermore, by providing multiple fixing parts such as the upper fixing part 2a and the lower fixing part 2b, the starter 1 with seal receiver itself can be used for top fastening or bottom fastening depending on the fixing position without rotating. Effect of the Invention

[0008] As described above, the present invention reduces the number of components and enables the same components to be used for both top and bottom fastening, improving workability and improving the strength of the surface on which exterior materials such as sandwich panels are placed.

[0011] The axes shown in each figure indicate the directions of each figure. The X-axis indicates the outdoor side (Xi)-indoor side (Xii), the Y-axis indicates the roof side (Yi)-foundation side (Yii), and the Z-axis indicates the horizontal direction. The axes shown in the other figures also indicate the same directions.

[0012] 1 shows a starter 1 with a seal receiver according to the present invention, which comprises a fixed surface 2, a mounting surface 3 protruding from the fixed surface 2 toward the outdoor side, a protruding piece 5 formed by bending the outdoor side end of the mounting surface 3 toward the base side toward a substantially vertical projection 6 provided between the protruding piece 5 and the mounting surface 3 and extending substantially vertically toward the roof side. A panel receiving portion 4 is provided on the indoor side of the mounting surface 3, and an inclined portion 7 and a convex portion 8 are provided at the end of the engaging portion 6. The fixed surface 2 is provided with an upper fixing portion 2a, a lower fixing portion 2b, and a fixed surface 2c, and a lower end portion 9 is provided at the base side end, and a seal receiving portion 10 is provided protruding substantially vertically from the fixed portion 2c toward the outdoor side.

[0013] The size of the panel receiving portion 4 is preferably about 1 / 3 to 1 / 2 of the mounting surface 3, and the thickness of the fixing surface 2c is preferably about 1 / 2 to 2 / 3 of the fixing surface 2. In addition, in consideration of ease of installation, the upper fixing portion 2a is preferably provided on the Yi direction side of the inclined portion 7. The lower fixing portion 2b is preferably provided on the Yi direction side of the midpoint in the Y axis direction between the mounting surface 3 and the seal receiving portion 10, and the fixing surface 2c is preferably provided on the Yii direction side of the midpoint in the Y axis direction between the mounting surface 3 and the seal receiving portion 10.

[0014] The starter 1 with seal receiver is preferably formed by aluminum molding, but may also be formed by extrusion molding, roll molding, or the like from metals (e.g., iron, copper, stainless steel, titanium, aluminum-zinc alloy plated steel sheet, etc.) or synthetic resins (e.g., polyvinyl chloride resin, polycarbonate resin, etc.).

[0015] 2 shows a conventional starter 11, which is generally U-shaped and is composed of a fixed surface 12, a receiving surface 13 provided generally perpendicular to the fixed surface 12, and an abutment surface 14 provided at the outdoor end of the receiving surface 13. Furthermore, a fixed portion 12a is provided on the fixed surface 12. The abutment surface 14 on the fixed portion 12a side is abutment surface 14a, and the abutment surface 14 located opposite the fixed portion 12a is abutment surface 14b, and the abutment surfaces 14a and 14b are provided symmetrically with respect to the receiving surface 13 as the axis of symmetry.

[0016] When the conventional starter 11 is installed, as shown in FIG. 2(a), if the fixing part 12a is provided on the roof side (Yi side) of the receiving surface 13, it can be installed by top fastening. Also, if the starter 11 is rotated 180 degrees so that the fixing part 12a is provided on the base side (Yii side) of the receiving surface 13, as shown in FIG. 2(b), it can be installed by bottom fastening. The conventional starter 11 was able to serve as both top fastening and bottom fastening with a single member, but the member itself had to be rotated depending on the fastening method. The starter 11 has an approximate U-shape, but the fixing surface 12 is not symmetrical with respect to the receiving surface 13 as the axis of symmetry. Therefore, when installed by bottom fastening, the distance between the receiving surface 13 and the fixing part 12a becomes too far, so there was a risk of excessive load being applied to the fixing part 12a. Also, when installing a sealant between the drip edge and the dripboard, it was necessary to prepare a seal receiving member 81 as shown in FIG. 8.

[0017] 3 shows an embodiment of a sandwich panel 21 used in the present invention, in which a core material 24 is filled between a surface material 22 and a backing material 23. The surface material 22 and the backing material 23 are made of steel plates (e.g., iron, copper, stainless steel, titanium, aluminum-zinc alloy plated steel plates, galvanized steel plates, enameled steel plates, clad steel plates, laminated steel plates (vinyl chloride steel plates, etc.), sandwich steel plates (vibration-damping steel plates, etc.), synthetic resin steel plate materials, e.g., polyvinyl chloride resin, polycarbonate resin, etc. (including, of course, steel plates toned in various colors and painted with these resins)), and are formed into various shapes by roll forming, press forming, etc. The core material 24 filled between them is made of a synthetic resin foam such as polyurethane foam, polyisocyanurate foam, polyvinyl chloride foam, polyethylene foam, urea foam, etc. For example, a solution of resol-type phenol is mixed with a hardener and a foaming agent, and the mixture is discharged onto the rear side of the front surface material 22 or the rear surface material 23, and then heated to cause reaction, foaming, and hardening. It is also possible to mix various types of flame retardant materials, such as lightweight aggregates (perlite particles, glass beads, gypsum slag, talc stone, silt balloons, aluminum hydroxide, etc.) and fibrous materials (glass wool, rock wool, carbon fiber, graphite, etc.) into the core material 24 to improve fire prevention and fire resistance.

[0018] The upper and lower ends in the width direction (Z-axis) of sandwich panel 21 consist of male portion 25 and female portion 26. Male portion 25 is provided with a step 27, a fixing screw recess 28, an insertion protrusion 29, an abutment edge 30, and an insertion protrusion 31.

[0019] The female part 26 is provided with a cover part 32, a fitting recess 33, an abutment part 34, a fitting recess 35, a connecting protrusion 36, and a packing 37. The packing 37 is, for example, a polyvinyl chloride-based, chloroprene-based, chlorosulfonated polyethylene-based, ethylene propylene-based, asphalt-containing polyurethane-based, EPM, EPDM, or other commonly available commercially available material.

[0020] 4 shows one embodiment of a drip rack 40 used in the present invention, which is composed of a fixed surface 41, an inclined surface 42 that protrudes from the fixed surface 41 toward the outside, and a decorative surface 43 that is bent from the inclined surface 42 toward the base (Yii side). The material may be a metal plate such as iron, aluminum, copper, stainless steel, titanium, aluminum-zinc alloy plated steel plate, galvalume steel plate, enamel steel plate, clad steel plate, laminated steel plate (PVC steel plate, etc.), sandwich steel plate (vibration-damping steel plate, etc.) (including, of course, color plates and embossed plates painted in various colors).

[0021] Fig. 5 shows a construction method for bottom-fixing the starter 1 with a seal receiver according to the present invention, and Fig. 6 is a construction diagram of one embodiment when construction is performed with bottom fixing. The general construction method for a starter with a seal receiver is to mark out, then attach the drain 40 to the furring strip 51, and after marking out again for the starter, fix the starter 1 with the seal receiver to the furring strip 51 using the fixing device 54 at the lower fixing part 2b, and install the sandwich panel 21 as shown in Fig. 6. The procedure is similar when construction is performed with top fixing, and the upper fixing part 2a is used for fixing to the furring strip 51.

[0022] When the sandwich panel 21 receives pressure (mainly wind pressure) from the Xi side toward the Xii side and the cover piece 32 is deformed, the protruding piece 5 serves as a pressing member, thereby minimizing the deformation of the cover piece 32. In addition, the inclined portion 7 is inclined from the Xi side toward the Xii side so that if the abutment portion 34 hits the sandwich panel 21 during installation, the abutment portion 34 can be smoothly guided to the mounting surface 3. Furthermore, by providing the inclined portion 7 and the protruding portion 8, a large contact area with the packing 37 after installation can be secured, thereby providing higher waterproofing against rainwater, etc., which tries to infiltrate from the Xi side toward the Xii side.

[0023] When the starter 1 with the seal receiver does not require a gap between the inclined surface 42 of the drain 40 and the cover part of the sandwich panel 21, the lower end 9 of the starter 1 with the seal receiver can be installed by abutting it against the indoor end of the inclined surface 42 of the drain 40. Therefore, the process of marking out the starter can be omitted, improving the ease of installation.

[0024] When installing with bottom fastening, the lower fixing part 2b is used and it can be fixed to the furring strip 51 at a position close to the panel receiving part 4, so the load on the mounting surface 3, panel receiving part 4 and locking part 6 can also be distributed to the fixing device 54, and deformation of the starter with seal receiver 1 can be suppressed. If the lower end part 9 of the starter with seal receiver 1 is abutted against the drain 40, this load can be further distributed.

[0025] FIG. 7 is a construction diagram showing an example of construction of the starter 1 with a seal receiver by top fastening. This construction method can be used when the size of the furring strip can be sufficiently secured, or when sealing 71 is required in the gap from the cover part 32 to the drain 40. When construction is performed by top fastening, the back-up material 73 can be constructed along the base side (Yii side) of the seal receiver part 10 of the starter 1 with a seal receiver, and then the sealing 71 can be constructed. Since there is no need to prepare a separate sealing receiver member, the sealing material can be constructed more smoothly even when sealing is required at the site after the sandwich panel 21 is constructed.

[0026] 8 is a construction diagram showing an example in which a conventional starter 11 is used. Since the starter 11 is not provided with a seal receiver, it was necessary to prepare a seal receiver member 81 as a separate member and fasten it to the starter 11.

[0027] What has been disclosed above is only one embodiment, and a simpler shape may be used as long as sufficient strength as a starter can be ensured. For example, the protruding piece 5 may be omitted if deformation of the cover portion 32 of the sandwich panel 21 can be suppressed. [Explanation of symbols]
