<Configuration of exterior panel accessory>
As shown in FIGS. 1, 2, and 3, an exterior panel accessory 30 according to the present invention includes a base material 33 and a cover material that cover end portions 32 a of a pair of exterior panels 32 provided on an outer wall body 31 of a building. 34 is a long exterior panel accessory.

  The cross-sectional shape of the exterior panel accessory 30 is bilaterally symmetric, and the base member 33 has a top surface 35a (width S1 = 6.5 mm) and an inclined surface 35b (height T1 = 9 mm) widening with respect to the symmetry axis R. A trapezoidal convex portion 35 including a vertical surface 36a (length S2 = 4 mm) with respect to the symmetry axis R from the lower end 35c of the inclined surface 35b, and a corner portion 36 that bends toward the symmetry axis R at a parallel surface 36b. Here, the parallel surface 36b is formed away from the axis of symmetry R, and the parallel surface 36b has a height T2 = 3 mm and a length S3 = 4 mm between the parallel surfaces 36b.

  Further, an attachment portion 37 (full length S5 = 67 mm) is extended from the lower end 36c of the parallel surface 36b along the outer wall main body 31, but a protrusion 39 (height T3 = parallel to the symmetry axis R in the vicinity of the convex portion 35. 6 mm) is formed. The distance S4 between the convex portion 35 and the protrusion 39 is 4 mm.

  Further, both end portions 37a of the attachment portion 37 are folded back to form a swash plate 38 having a length S6 = 5 mm. The swash plate 38 has a height Q = 3 mm from the mounting portion 37.

  The cover material 34 folds back the first surface portion 40 (horizontal total length S7 = 45 mm) substantially parallel to the attachment portion 37 of the base material 33 at both ends 40a, and the second surface along the back surface of the first surface portion 40. The surface portion 41 is formed.

  Then, a pair of leg portions 42 (length T4 = length T4 = the angle θ = 83 degrees with respect to the horizontal line covering the convex portion 35 from the tip 41a of the second surface portion 41 (length S9 = 8 mm between both tips 41a). 20 mm).

  Further, the claw portion 43 is bent at an angle α = 70 degrees so as to be engaged with the vertical surface 36a of the corner portion 36 from the lower end 42a of the pair of leg portions 42 (length S12 = 13 mm between the lower ends 42a). (Length S10 = 3 mm, gap S11 = 5 mm between the pair of claws 43) is formed. The horizontal length S13 of the claw portion 43 is 4 mm.

  Here, the first surface portion 40 and the second surface portion 41 are inclined at an angle β = 20 degrees from a position 44 having a length S8 = 21 mm across the axis of symmetry R, and the inclined portion 45a is sealed for waterproofing. The material 45 is fixed.

  The base material 33 and the cover material 34 are continuously formed integrally by sheet metal processing using a steel plate base material. As shown in FIG. 4, the steel plate base material Y as the base material 33 is an acid-resistant coated steel plate, and the structure thereof is galvanized Y2 and chromic acid anticorrosive treatment layer Y3 on both surfaces of a thin steel plate Y1 having a thickness of 0.4 mm. In addition, both surfaces and both side surfaces are coated with a special polymer resin Y5 such as a vinyl chloride resin via a special adhesive layer Y4 to form a total plate thickness of 0.6 mm.

  The cover material 34 is made of a thin steel plate with aluminum / zinc alloy plating on both surfaces of a 0.4 mm-thick steel plate, a material with a fluorine resin coating on the front side and a polyester resin coating on the back side. It is done.

  When the base material 33 of the exterior panel accessory 30 is fixed to the outer wall main body 31, the mounting portion 37 of the base material 33 is fixed to the outer wall main body 31 via the first fixing tool 31a such as two sets of screws. At the same time, it is fixed to the outer wall main body 31 from the top surface 35a of the convex portion 35 via the second fixing tool 31b.

  Here, for the purpose of heat insulation, sound insulation, etc., the exterior panel 32 uses a metal siding with a thickness of H1 = 21 mm formed by coating an internal heat insulating material with a thin metal plate (not shown), and unevenness not shown on the surface. A pattern may be formed.

  The relationship between the thickness H1 of the exterior panel 32, the gap H between the both ends 40a of the cover material 34 and the mounting portion 37 of the base material 33, the gap H3 between the both ends 40a and the exterior panel 32, and the height Q is H = H1 + Q + H3. The clearance H3 is determined in consideration of the compression allowance of the packing material 45 necessary for waterproofing.

  The plurality of exterior panels 32 may be attached horizontally in order from the bottom to the top of the outer wall main body 31 or may be attached vertically in the left-right direction. Moreover, it may attach through the trunk edge which is not shown in figure. The exterior panel accessory 30 is provided with a waterproof measure using a seal material (not shown) separately from the packing material 45 when necessary.

<Action of exterior panel accessory>
As described above, the coating material used for the steel plate base material Y of the base material 33 is a special polymer resin Y5 such as a vinyl chloride resin, and since the coating material has elasticity, it is excellent in bending formability. Further, since the air is blocked by the special polymer resin Y5, the base material 33 is finished in a structure resistant to rust.

  For this reason, even if rainwater enters, the steel plate base material Y does not rust, so that the exterior panel 32 is not deteriorated due to the rust and the soundproofing and heat retaining properties are not lowered.

  Since the top surface 35a of the trapezoidal convex portion 35 of the base material 33 has a width S1 = 6.5 mm and a length S3 = 4 mm between the parallel surfaces 36b of the corner portions 36, the distance between the top surface 35a and the parallel surface 36b is the second. An area sufficient for driving the fixing tool 31b is held.

  For this reason, since the base material 33 can be reliably and easily fixed to the outer wall main body 31 without damaging the base material 33, rainwater permeates and the exterior panel is deteriorated, so that soundproofing and heat retention are reduced. This is no longer the case.

  Further, since the distance S4 = 4 mm between the convex portion 35 and the protrusion 39 and the horizontal length S13 = 4 mm of the claw portion 43 are formed to be substantially equal, the claw is inserted when the cover material 34 is inserted into the base material 33. The portion 43 can be smoothly inserted without damaging the exterior panel 32. For this reason, waterproof performance can be improved.

  While the claw portions 43 of the pair of leg portions 42 move along the inclined surface 35b of the base member 33, the leg portions 42 are elastically opened and inserted, and in a state where they are locked to the vertical surface 36a, the leg portions 42 are Since it returns to a natural state, the cover material 34 can be reliably latched to the base material 33.

  Since the base material and the cover material are integrally formed by sheet metal processing using a steel plate base material, they can be easily manufactured at low cost.

<Second Embodiment>
A second embodiment of the present invention will be described with reference to FIGS. 5 to 7, and the same components as those of the exterior panel accessory 30 shown in FIGS. Thus, duplicate explanations are omitted. Since the configuration is completely the same as that of FIG.

  As shown in FIGS. 5, 6, and 7, the exterior panel accessory 30 a includes a base material 33 a and a cover that cover the end portions 32 a of the pair of exterior panels 32 provided on the outer wall body 31 at the projecting corner of the building. The cross-sectional shape of the long exterior panel accessory made of the material 34a is symmetrical.

  The base material 33a has an opening θ1 = 90 degrees from the lower end 36c of the parallel surface 36b along the outer wall main body 31 and a one-side attachment portion 37 having a length K1 = 40 mm. The length K2 = 61 mm. The height K3 between the convex portion 35 and the end portion 37a is 41 mm, and the interval Q1 between the convex portion 35 and the protrusion 39 is 8 mm.

  The cover material 34a has a first surface portion 40 with an opening degree θ1 = 90 degrees, and a length K4 = 57 mm between both ends 40a. The first surface portion 40 and the second surface portion 41 have a length K5 = 13 mm from both ends 40a to a position 44 inclined at an angle β1 = 10 degrees, and a waterproof packing material 45 is fixed to the inclined portion. The

  The length Q2 between both lower ends 42a of the pair of leg portions 42 is 12 mm. The gap between the pair of claw portions 43 is Q3 = 3 mm, and the claw portion 43 is formed with a horizontal length Q4 = 4 mm.

  The attachment portion 37 of the base material 33a is fixed to the outer wall main body 31 via first fixing tools 31a such as two sets of screws on the left and right sides.

  If it is this exterior panel accessory, it can be used easily and reliably in the corners, and the same effect as in the first embodiment can be obtained.

  As mentioned above, although embodiment of this invention was described based on drawing, all said Example shows an example of this invention, and it cannot be overemphasized that this invention should not be limited to these.

  For example, the length S9 = 8 mm between the two tips 41a of the second surface portion 41, and an area sufficient for driving the second fixing tool 31b is held. For this reason, the second fixing tool 31 b can be driven from the first surface portion 40 and can be fixed to the outer wall main body 31 through the top surface 35 a of the convex portion 35.

  The shape of the cover member 34a in FIG. 7 is such that the first surface portion 40 in the vicinity of the symmetry axis R is bent at a right angle with respect to the symmetry axis R at the same position as both ends 41a of the second surface portion 41. I do not care. In this case, since the second fixing tool 31b is perpendicular to the first surface portion 40, it can be driven easily.

  The opening θ1 of the first surface portion 40 of the cover material 34a can be finely adjusted to an angle other than 90 degrees.

  The exterior panel accessory can be used for metal siding other than the thickness H1 = 21 mm by adjusting the length T4 of the leg portion. The exterior panel accessory can be used regardless of whether the end of the exterior panel is in the vertical or horizontal direction.
