Description

[Technical field]

[0001] The present invention relates to a starter for use in constructing sandwich panels. [Background technology]

[0002] Sandwich panels, which are made by sandwiching a core of insulating material between two metal steel sheets, are often used as exterior materials for reinforced concrete and steel buildings, and many have been invented, devised and marketed so far. Furthermore, there are many construction methods that realize ease of construction and high aesthetics. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2006-083652 A [Patent Document 2] JP 2007-303150 A Summary of the Invention [Problem to be solved by the invention]

[0004] Generally, construction of the base involves marking out the foundation, setting up the drip-proofing material, attaching backboards to vertical joints and protruding and recessed corners, as well as installing the starter and constructing the main body. Starters are generally constructed using top fastening, with a fixing surface provided on the upper side of the mounting surface so that the screw heads are completely hidden by the subsequent construction of the main body. However, in Reference 1, a horizontal furring strip with a width greater than or equal to the fixing surface and the length of the fastening hardware of the starter is required, while in Reference 2, the positions where the fastening hardware can be installed are limited, and in both cases the degree of freedom in the construction position of the starter is limited. For this reason, in some cases, construction using bottom fastening, with a fixing surface provided on the lower side of the mounting surface, is performed.

[0005] This bottom fastening is effective when the shaped steel that will be the furring strip is small (for example, 100 mm x 50 mm C-shaped steel) or when no gap is required between the bottom end of the sandwich panel body and the water drain. However, because the starter cannot be hidden by the sandwich panel body like with top fastening, it detracts from the aesthetics. Also, when top fastening and bottom fastening must be used depending on the building or construction site, the starter must be manufactured by on-site processing or specialized parts must be stocked, leaving room for improvement in terms of workability and economy. [Means for solving the problem]

[0006] Therefore, the present invention provides a starter characterized by an approximately L-shaped configuration that has a mounting surface on which a sandwich panel can be placed, and the indoor end of the mounting surface bent approximately vertically and composed of a protrusion, a fixing surface, a convex portion, an inclined portion and an end, and that can be fixed to an underlying material such as a furring strip via the fixing surface with a fastener such as a screw.

[0007] Furthermore, when the product of the present invention is used in an upper fastening manner in which the fixing surface 4 is arranged above the support surface 2 as shown in Figure 7, even if the end of the sandwich panel happens to get caught on the end of the starter 1 when installing the sandwich panel, the inclined portion 6 allows the sandwich panel to be smoothly guided to the support surface 2 without deforming the back surface of the panel.

[0008] Furthermore, in the present invention, when used in bottom mounting where the fixing surface 4 is positioned below the support surface 2 as shown in Figure 6, by installing the end 7 by abutting it against the indoor end of the slope 42 of the drip edge 41, not only is it possible to reduce the marking out process when installing the starter 1, but also because the fixing part 4a is at approximately the same height from the ground as the covering part 38 when the sandwich panel 20 is installed vertically, even in bottom mounting, the starter 1 is not visible from the outdoors, resulting in a pleasing appearance. Effect of the Invention

[0009] As described above, the present invention allows a single component to be used for both upper and lower fastenings, improving workability by eliminating some of the marking steps, and also achieving a pleasing appearance without compromising aesthetics. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS EXAMPLES

[0011] Hereinafter, an embodiment of the starter and its mounting structure according to the present invention will be described in detail with reference to the drawings. In the description of the drawings, the same elements are given the same reference numerals, and duplicated description is omitted. FIG. 1(a) is a side view of the starter according to the present invention, and FIG. 1(b) is a perspective view of the starter according to the present invention. FIG. 2(a) is a side view of a conventional starter, and FIG. 2(b) is a perspective view of the conventional starter. FIG. 3 is a perspective view of an embodiment of the sandwich panel used in the present invention when installed vertically. FIG. 4 is a horizontal cross-sectional view of the sandwich panel used in the present invention when installed vertically. FIG. 5 is a vertical side view of the sandwich panel used in the present invention when installed vertically. FIG. 6 is a construction diagram showing an embodiment of the starter according to the present invention when installed at the bottom fastening, and FIG. 7 is a construction diagram showing an embodiment of the starter according to the present invention when installed at the top fastening. FIG. 8 is a construction diagram showing an embodiment of the starter according to the present invention when installed at the top of an opening.

[0012] 2 shows a conventional starter 11, which is made up of a nearly horizontal mounting surface 12 and a fixing surface 13 hanging down from the indoor end, and has a nearly L-shaped cross section. Furthermore, fixing surface 13 is provided with a fixing portion 13a which serves as a guide when driving in the screws.

[0013] Fig. 3 shows an example of a sandwich panel 20 installed vertically. The axes shown in the figure indicate the directions of each figure. The X-axis indicates the outdoor side (Xi)-indoor side (Xii), the Y-axis indicates Yi (roof side)-Yii (foundation side), and the Z-axis indicates the horizontal direction, and the axes shown in the other figures also indicate the same directions.

[0014] The conventional starter 11 shown in FIG. 2 is a starter that can only be used for bottom fastening. If the starter 11 is installed by top fastening, a fastener or the like is driven into the fixing portion 13a and fixed to the furring strip 45, and the head of the fastener protrudes from the fixing surface 13. As a result, when the sandwich panel 20 is placed on the mounting surface 12, the contact surface between the sandwich panel 20 and the mounting surface 12 becomes narrow, and there is a risk that the sandwich panel 20 will fall, and there is a risk that the starter will not be able to perform its original function. In addition, the end portion 14 provided adjacent to the fixing surface 13 has a flat shape. Therefore, if the sandwich panel 20 is caught on this end portion 14 when the sandwich panel 20 is installed, there is a risk that the sandwich panel 20 will be deformed.

[0015] A starter 1 according to the present invention has a substantially L-shaped cross section, as shown in Fig. 1. In more detail, the mounting surface 2 of starter 1 is set substantially horizontally, and the indoor end is bent substantially vertically to provide a protrusion 3 and a fixing surface 4. Furthermore, a convex portion 5 is provided at the end of the fixing surface opposite to protrusion 3, and beyond that a sloping portion 6 and an end 7 are provided. A fixing portion 4a is formed on fixing surface 4 to serve as a guide when fixing with a fixing tool such as a screw.

[0016] The starter 1 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.).

[0017] The protrusions 3 are provided to increase the strength of the starter 1 and to prevent deformation when the sandwich panel 20 is placed on the placement surface 2.

[0018] The inclined portion 6 is inclined from the indoor side to the outdoor side toward the mounting surface 2. As a result, even if the end of the sandwich panel 20 comes into contact with the inclined portion 6 when the sandwich panel 20 is installed on the mounting surface 2, the back surface 22 is not peeled off and the sandwich panel 20 can be smoothly guided to the mounting surface 2. Furthermore, the convex portion 5 adjacent to the outdoor end of the inclined portion 6 protrudes to a height approximately equal to that of the protruding portion 3. This makes it possible to prevent interference between the sandwich panel 20 and the fixing device 44 for attaching the starter 1 to the furring strip 45, and therefore makes it possible to minimize unevenness of the sandwich panel 20.

[0019] 4 and 5 show an embodiment of a sandwich panel 20 to be constructed using the starter according to the present invention. The decorative surface 21 and the back surface 22 of the sandwich panel 20 are made of steel plates (for example, iron, copper, stainless steel, titanium, aluminum-zinc alloy plated steel plates, galvanized steel plates, enameled steel plates, clad steel plates, laminated steel plates (PVC steel plates, etc.), sandwich steel plates (vibration-damping steel plates, etc.), synthetic resin steel plates, for example, polyvinyl chloride resin, polycarbonate resin, etc. (including, of course, steel plates toned and painted in various colors)), and are formed into various shapes by roll forming, press forming, etc. The core material 23 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, a hardener, and a foaming agent are mixed, and the mixture is discharged to the back side of the decorative surface 21 or the back surface 22, and heated to react, foam, and harden. It is also possible to mix various flame retardant materials, such as lightweight aggregates (perlite granules, glass beads, gypsum slag, talc, silica balloons, aluminum hydroxide, etc.) and fibrous materials (glass wool, rock wool, carbon fiber, graphite, etc.) into the core material 23 to improve fire resistance and fire prevention.

[0020] 4 is a cross-sectional view of sandwich panel 20 cut horizontally (Z-axis) during construction. As shown in FIG. 4, female part 24 is provided with cover part 26, fitting recess 27, abutting edge 28, fitting recess 29, connecting protrusion 30, and packing 31.

[0021] The packing 31 in the fitting recess 27 is formed to improve fire resistance, waterproofing, airtightness, etc. The packing 31 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.

[0022] As shown in FIG. 4, the male part 25 is provided with a step 32, a fixing screw recess 33, an insertion protrusion 34, an abutment edge 35, and an insertion protrusion 36.

[0023] 5 is a vertical (Y-axis) side view of sandwich panel 20 when installed vertically. Covering portion 37 and covering portion 38 are provided at the Y-axis end of sandwich panel 20, and core material 23 is not exposed.

[0024] Figures 6, 7, and 8 show examples of construction using the starter 1. Figure 6 shows an example of "bottom fastening" construction in which the fixing surface 4 is located below the placement surface 2, while Figures 7 and 8 show examples of "top fastening" construction in which the fixing surface 4 is located above the placement surface 2.

[0025] The general construction order for the starter is to mark out, then attach the flashing 41, mark out again for the starter, and then attach the starter 1 and the sandwich panel 20 in that order. When construction is performed with bottom fastening as shown in Figure 6, this is a construction method that can be used when the furring strips 45 (for example, shaped steel used in steel frame structures such as C-shaped steel, H-shaped steel, I-shaped steel, steel pipes, etc.) are thin in the Y-axis direction or when no gap is required from the slope 42 of the flashing 41 to the covering part 38.

[0026] When using the starter 1 for bottom mounting, the end 7 of the starter 1 can be abutted against the part consisting of the fixing surface 43 and the slope 42 of the drip edge 41. At this time, the fixing part 4a and the covering part 38 are located at approximately the same height in the Y-axis direction, so the fixture 44 is not visible from the outside and does not spoil the appearance. Therefore, there is no longer any need to mark out the starter, which was previously necessary after installing the drip edge 41, improving workability.

[0027] On the other hand, top-fastening construction as shown in Figures 7 and 8 is a construction method used when the size of the furring strip 45 can be sufficiently secured, when bottom-fastening construction is difficult, or when sealing is required between the slope 42 and the covering portion 38. Top-fastening allows the fixing device 44 to be hidden by the sandwich panel 20, improving the degree of freedom in designing the gap between the slope 42 of the flashing 41 and the covering portion 38.

[0028] The above disclosure is merely one embodiment, and the protrusion 3 may be omitted as long as the sandwich panel 20 can be sufficiently supported. Also, the grooves and inclined portions 6 such as the fixing portions 4a may be omitted. [Explanation of symbols]
