Description

[Technical field]

[0001] The present invention relates to a vertical roof structure in which vertical roof panels can be easily formed and which provides strong retention and reliable waterproofing. [Background technology]

[0002] 2. Description of the Related Art Conventionally, a structure such as that disclosed in Patent Document 1 has been proposed as a roof structure using flat roof panels whose left and right side edges are not processed. The roof panels used in Patent Document 1 do not have raised portions (seam portions) formed on the side edges, and therefore have the advantage that rolled metal sheet material can be brought to the site, cut to the required length on site, and used for construction.

[0003] However, while the roof structure proposed in the above-mentioned Patent Document 1 is certainly superior in terms of the molding process of the roof panels, since it only clamps the side edges of the roof panels, the clamping can easily come undone when, for example, negative pressure is applied to the roof surface. In other words, when the face panel is pulled upward, the clamped side edges can easily come undone, causing the roof panels to come off and fall or be blown away by the wind, which can cause accidents. In addition, since the roof panels are merely clamped at their side edges, thin film or other debris can easily find its way behind the panels, resulting in water leakage.

[0004] For this reason, the inventors proposed structures in which the left and right side edges are slightly shaped to ensure stable support, as disclosed in Patent Documents 2 and 3. Of these, the roof structure proposed in Patent Document 2 has a long hole-shaped through hole formed in the side edge of the roof panel, which is sandwiched between an upper member and a lower member, while the roof structure proposed in Patent Document 3 has a Z-shaped locking portion formed in a side view, which is sandwiched between an upper member and a lower member.

[0005] [Patent Document 1] Japanese Utility Model Application Publication No. 2-143419 [Patent Document 2] Patent No. 2569266 [Patent Document 3] Patent No. 2874822 Summary of the Invention [Problem to be solved by the invention]

[0006] However, in the case of Patent Document 2, since a plurality of through holes are formed in the roof panel, it is unavoidable that rainwater will leak in through the through holes. Also, in the case of Patent Document 3, the locking portion having a Z-shape in a side view does not provide sufficient locking action or water return action. SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to propose a vertical roof structure in which vertical roof panels can be easily formed and which provides strong retention and reliable waterproofing. [Means for solving the problem]

[0007] The present invention has been proposed in view of the above, and is a vertical roof structure in which the side edges of adjacent vertical roof panels are connected by being clamped between a pair of left and right upper retaining members and lower retaining members, the vertical roof panels having side edges formed in a downward step shape at the left and right edges of the face plate portion, the tips of which are bent upward, the lower retaining members having a fixing portion to the base, a pair of left and right mounting portions, and a support portion by which the side edges of the vertical roof panels are supported from below, An upward protrusion is provided at an upper end and a lower end of the fixing portion in a flow direction, The upper holding member is provided at a side edge portion of one of the vertical roof boards adjacent to each other on the left and right. of The upper member includes a cover portion that covers the roof from above and an engagement portion that is attached to the attachment portion of the lower holding member, and a side edge portion of the other vertical roof board of the vertical roof boards adjacent to each other on the left and right. ofThe vertical roof shingles are arranged on the left and right of the lower holding member fixed on the base, and the engaging portion of the upper one member is engaged with the mounting portion of the lower holding member, and the engaging portion of the upper other member is engaged with the mounting portion of the lower holding member, and a cover material covering between the side edges of the left and right vertical roof shingles is attached to the upper holding member. From above This relates to a vertical roof structure characterized by being integrally assembled. Effect of the Invention

[0008] In the vertical roof structure of the present invention, only one of the adjacent vertical roof panels is held by the upper one member, and only the other vertical roof panel is held by the upper other member, so that it can be easily attached to the mounting part of the lower holding member, and provides strong holding action and reliable waterproofing. Therefore, even members smaller than 10 centimeters, for example, can be easily attached without any problems, and it can be applied to various vertical roof structures. Furthermore, the lower holding member has upward convex parts at the upper and lower ends in the flow direction, so that the upper one member and the upper other member are prevented from falling off in the flow direction.

[0009] Furthermore, when a drainage member having a raised portion in the center is placed on the base and the lower retaining member is placed on the raised portion and then fixed by driving in a fastener, even if rainwater or the like finds its way around to the back side of the side edge portion, it can be reliably drained away by the drainage portion of the drainage member.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] The vertically-roofed structure of the present invention is constructed by connecting adjacent vertically-roofed roof panels (hereinafter referred to as roof panels) at their side edges by clamping them between a pair of upper and lower retaining members on the left and right. The roof panel has left and right edges of a face plate portion which are formed in a downward step shape with side edges whose tips are bent upward. The lower retaining member includes a fixing portion for fixing to the base, a pair of left and right mounting portions, and a support portion for supporting the side edge portion of the roof panel from below. The fixing portion The nozzle has upwardly projecting portions at the upper and lower ends in the flow direction. The upper retaining member consists of an upper one member having a covering portion that covers from above the side edge portion (only) of one of the adjacent roof panels on the left and right and an engaging portion that is attached to the mounting portion of the lower retaining member, and an upper other member having a covering portion that covers from above the side edge portion (only) of the other adjacent roof panel on the left and right and an engaging portion that is attached to the mounting portion of the lower retaining member. The roof panels are then disposed on the left and right of a lower holding member fixed on a base, and the engaging portion of the upper one member is engaged with the mounting portion of the lower holding member, while the engaging portion of the upper other member is engaged with the mounting portion of the lower holding member. The upper one member and the upper other member are prevented from falling off in the flow direction by the convex portion of the lower holding member, and a cover material covering between the side edges of the left and right roof panels is attached to the upper holding member. From above It is characterized by being integrally assembled.

[0012] The roof panels, lower holding members, and upper holding members (upper one member, upper other member) that constitute the vertical roof structure will each be described in detail below.

[0013] The roof panel is configured so that the left and right edges of the panel portion are shaped in a downward step toward the back surface, with the tips of the edges being bent upward to form side edge portions, in other words, the panel portion has a downward step portion and a water-repelling piece-shaped side edge portion. The panel portion is not particularly limited to being flat or wavy, but as the purpose is to facilitate the molding (processing) of the roof panel as mentioned above, it is desirable to make it flat as in the illustrated embodiment described below. The roof panel is made from a known metal material and is formed (molded) by roll forming, press forming, or a combination of both. The thickness of the material is not particularly limited, but is generally about 0.4 to 1.6 mm.

[0014] As described above, the lower retaining member includes a fixing portion for fixing to the base, a pair of left and right mounting portions, and a support portion for supporting the side edge portion of the roof panel from below. The fixing portion The nozzle has an upward protrusion at each of the upper and lower ends in the flow direction. Since the support portion supports the side edge portions of adjacent roof panels from below, it may be formed on the left and right sides separately or may be formed as a continuous portion, and there are no particular limitations on its shape, etc. The mounting portion is a portion that connects with an engaging portion formed on the upper one member or the upper other member, and in the illustrated embodiment, is formed in a substantially U-shape with a space that opens upward at the substantially center, and a pair of left and right locking pieces that protrude toward the center are provided in the space, but this is not particularly limited. In other words, as long as they can be connected by engagement, the mounting portion and the engaging portion of the upper holding member may be formed in any manner. The lower holding member is a molded piece having a fixed length in the flow direction. Furthermore, an L-shaped piece may be formed on the outside of the support portion to support the lower step portion of the roof panel and the edge of the face plate portion from below, as shown in the illustrated embodiment described later. The horizontal piece (flange) of this L-shaped piece can be used as a mounting point for a snow guard, solar heat collector, etc.

[0015] In addition, upward convex portions are formed at the upper and lower ends of the fixing portion in the flow direction. do The protrusions can prevent the upper one member and the upper other member from falling off in the flow direction. The protrusions may be, for example, in the form of a claw formed by raising a notch as in the illustrated embodiment described later, or may be screws or the like.

[0016] As described above, the upper holding member is composed of a pair of upper one member and upper other member. Of these, the upper one-side member has a covering portion (hereinafter referred to as the one-side covering portion for the sake of distinction) that covers from above only the side edge portion of one of the adjacent roof panels on the left and right, and an engaging portion that is attached to the mounting portion of the lower retaining member. The upper other member also has a covering portion (other covering portion) that covers from above only the side edge portion of the other of the adjacent roof panels on the left and right, and an engaging portion that is attached to the mounting portion of the lower retaining member. Both the one covering part and the other covering part cover the side edge part of the roof panel from above, and particularly when these covering parts are formed into an L-shape to surround it from above, even if negative pressure or the like acts and it is pulled toward the center of the panel part, the tip of the side edge part abuts (engages) with the vertical piece of the L-shaped covering part, which is desirable in preventing it from coming off due to being pulled on the panel part. In addition, neither the upper one member nor the upper other member has a covering portion formed on the side opposite to the side on which the covering portion is formed, as in the illustrated embodiment described later. The engaging portion is a portion that is provided on both the upper one member and the upper other member, and is a portion that connects to the mounting portion provided on the lower retaining member. In the illustrated embodiment, a pair of left and right half-arrowhead-shaped pieces that become thicker from bottom to top are provided on the outside of the approximately U-shaped portion, but this is not particularly limited. The upper one member and the upper other member are provided with fixed receiving portions for mounting a cover material that is continuous in the flow direction, and these members are formed as molded pieces of a fixed length.

[0017] As mentioned above, the engaging portions of the upper one member and the upper other member and the mounting portion of the lower retaining member may be formed in any manner so long as they can be connected by engagement, and it is preferable that they be pressed from above to elastically fit together, as in the illustrated embodiment described below.

[0018] The side edge portion of the roof panel is covered from above by one covering portion of the upper one member and the other covering portion of the upper other member, and is supported from below by the support portion of the lower retaining member, thereby forming a clamped portion that is held in a clamped manner from above and below. As the tip of this side edge is bent upwardly to form a water-repelling piece as mentioned above, it is desirable to form the covering portion (one covering portion and the other covering portion) into an L shape so that the tips abut (engage).

[0019] In addition, in the vertical roof structure of the present invention, it is preferable to arrange drainage members between adjacent roof panels on the left and right, and in particular, it is preferable to arrange a drainage member with a raised part in the center on the base and to drive in the fasteners to fix the lower retaining member with the lower retaining member arranged on the raised part. This is because even if rainwater or the like gets around to the back side of the side edge part, it can be reliably drained down by the drainage part of the drainage member.

[0020] Furthermore, as described above, the upper one member and the upper other member are provided with fixed receiving portions for mounting the cover material that is continuous in the flow direction, and the cover material can prevent the infiltration of rainwater, etc. The covering material is a continuous material having a covering portion that covers at least the space between the side edges of the left and right roof panels, and has a fixing portion that is attached to the fixing receiver. The covering portion is a portion that covers the side edges of the roof panels, and it is preferable that a water-stopping material such as a double-sided adhesive foam material is interposed when the covering portion is arranged to prevent the infiltration of rainwater, etc. from between the side edges. The fixing portion is a portion that is connected by engagement or the like to a fixing receiver provided on the upper one member or the upper other member, and these fixing receivers and fixing portions may be formed in any manner as long as they can be connected by engagement, fitting, etc. EXAMPLES

[0021] Figure 1 shows a pair of left and right upper retaining members 3 (3A, 3B) and a lower retaining member 2 used in the vertical roof structure of Example 1 of the present invention, with Figure 1(a) being a three-sided view (plan view, front view, left side view) of the upper one member 3A, Figure 1(b) being a three-sided view (plan view, front view, right side view) of the lower retaining member 2 used, and Figure 1(c) being a three-sided view (plan view, front view, left side view) of the upper other member 3B used. Between the plan view and front view of Figure 1(b) a front view of the roof panel 1 used is shown in dotted lines, thereby showing the installation state of the roof panel 1 to the lower retaining member 2.

[0022] To briefly explain each component, the roof panel 1 has a downward step shape formed on each of the left and right edges of the panel portion 11 (downward step portion 12), and the tip of the step portion is bent upward to form a side edge portion 13. The lower retaining member 2 also includes a fixing portion 22 for fixing to a base (not shown), a pair of left and right mounting portions 23, and a support portion 24 for supporting the side edge portion 13 of the roof panel 1 from below. Furthermore, the upper retaining member 3A consists of a pair of left and right upper one members 3A and upper other members 3B, and the upper one member 3A has a covering portion 31a that covers from above only the side edge portion 13 of one of the roof panels 1, 1 adjacent to the left and right, and an engaging portion 33 that is attached to the mounting portion 23 of the lower retaining member 2, and the upper other member 3B has a covering portion 31b that covers from above only the side edge portion 13 of the other roof panel 1 of the roof panels 1, 1 adjacent to the left and right, and an engaging portion 33 that is attached to the mounting portion 23 of the lower retaining member 2.

[0023] In this illustrated embodiment, the roof panel 1 has a face panel portion 11, which is a substantially horizontal flat plate portion, and a descending step portion 12 and a water-repellent piece-shaped side edge portion 13 on the left and right edges thereof. The panel is formed (molded) by roll forming, press molding, or a combination of both, and the material thickness is molded to be approximately 0.4 to 1.6 mm. The descending step portion 12 and the side edge portion 13 are formed in a substantially Z-shape, and are stably held when supported by the support portion 24 of the lower holding member 2.

[0024] 1(b), the lower holding member 2 is a member in this illustrated embodiment in which the left and right vertical pieces 21, 21 of a substantially H-shape are widely expanded, and the substantially horizontal horizontal piece 22 connecting the vertical pieces 21, 21 is a fixing part to a base not shown in FIG. 1, and a hole 220 formed in the substantially center of the member as shown in the plan view is an attachment hole for a fastener 2b. The space above the fixing part 22 is an attachment part 23 for attaching a substantially U-shaped engagement part 33 provided on the upper one member 3A or the upper other member 3B, and more specifically, a pair of left and right protruding pieces 331, 331 formed on the outside of the substantially U-shaped part 33 elastically engage (fit) with a pair of left and right locking pieces 231, 231 protruding toward the center in the space of the attachment part 23. At the upper end (front end in the drawing) and lower end (rear end in the drawing) in the flow direction of the fixing portion 22, claw-like protrusions 221, 221 are formed by raising notches. Additionally, the horizontal piece 24 extending substantially horizontally from the upper ends of the left and right vertical pieces 21, 21 toward the ends is a support portion that supports the side edge portion 13 of the roof panel 1 from below, and the L-shaped piece 25 extending further outward is a support portion that supports the edge of the descending step portion 12 and the face plate portion 11. Since a protrusion 232 is formed at the upper end of the vertical piece 21 and a protrusion 251 is also formed on the center side of the horizontal piece of the support portion 25, the support portion 24 is formed in an enclosure dish shape that is open at the top, and can stably hold the side edge portion 13 of the roof panel 1 in an engaged state when it is supported.

[0025] 1(a), the upper one member 3A is a member in this illustrated embodiment in which the upper end of one (left) U-shaped vertical piece is extended toward the end, and is a molded material of a certain length that includes a U-shaped engaging portion 33 attached to the mounting portion 22 of the lower holding member 2, and an L-shaped one covering portion 31a that extends from the upper end of the one (left) vertical piece of the engaging portion 33 toward the end and covers the side edge portion 13 of the roof panel 1 from above. Note that a pushing portion 32a that extends slightly toward the end is provided at the upper end of the other (right) vertical piece of the engaging portion 33. Furthermore, a pair of left and right half arrowhead-shaped pieces which become thicker from bottom to top are provided on the outside of the engagement portion 33 (U-shaped) as engagement pieces 331, 331, and a pair of left and right half arrowhead-shaped pieces which become thicker from top to bottom are provided on the inside of the engagement portion 33 (U-shaped) as locking pieces 332, 332. These upper one member 3A and upper other member 3B are formed of molded material of a fixed length as described above, but the dimension in the flow direction thereof is formed to be half or less of the length of the lower holding member 2 in the flow direction.

[0026] 1(c), the upper other member 3B is a member in which the upper end of one (right) vertical piece of a U-shape is extended toward the end, and is a member symmetrical to the upper one member 3A. Therefore, like the upper one member 3A, it has a U-shaped engaging portion 33 attached to the mounting portion 22 of the lower holding member 2, but is a molded material of a certain length that has an L-shaped other covering portion 31b that extends from the upper end of one (right) vertical piece of the engaging portion 33 toward the end and covers the side edge portion 13 of the roof panel 1 from above, and a pushing portion 32b that extends slightly toward the end is provided at the upper end of the other (left) vertical piece of the engaging portion 33.

[0027] To dispose the roof panels 1, 1 on the lower holding member 2, the side edge portions 13, 13 of the roof panels 1, 1 are supported by the supports 24, 24 provided on the lower holding member 2 as shown in FIG. 1(b). In this case, the support portion 24 has a protrusion piece 232 at the center and a protrusion piece 251 extending from the receiving support portion 25 at the end, as shown in Figure 1 (d), so that it is shaped like an enclosed dish with an open upper portion, and can stably hold the side edge portion 13 of the roof panel 1 in an engaged state.

[0028] Thereafter, the engaging portion 33 of the upper one member 3A is engaged with the mounting portion 23 of the lower holding member 2 as shown in FIG. 1(e), and the engaging portion 33 of the upper other member 3B is engaged with the mounting portion 23 of the lower holding member 2 as shown in FIG. 1(f). At that time, the upper one member 3A and the upper other member 3B can be attached in an inclined manner so that the one cover portion 31a and the other cover portion 31b face upward as shown by the dotted line, and can be rotated to engage with the attachment portion 23. In other words, if the pushing portions 32a, 32b on which the covering portions 31a, 31b are not formed face downward and are rotated, the pushing portions 32a, 32b can be rotated close to the upper end of the attachment portion 23, and therefore can be easily engaged.

[0029] 2(a) to 2(c) are perspective views showing the upper one member 3A, the upper other member 3B, and the lower holding member 2, as well as their engaged states. Figure 2(d) is an exploded oblique view of the state in which the side edge 13 of the roof panel 1 is clamped between the upper holding members (3A, 3B) and the lower holding member 2 on the drainage member 6 and a cover material 5 is arranged, and Figure 2(e) is an oblique view showing the state in which the upper holding members (3A, 3B) are attached to the lower holding member 2 arranged on the drainage member 6, and the positional relationship between the left and right vertical roof panels 1, 1 and the cover material 5.

[0030] The drainage member 6 has a protruding portion 62 that protrudes upward approximately at the center of a bottom surface portion 61, and the left and right ends of the bottom surface portion 61 are raised upward to form side surfaces 63, 63, with drainage portions formed on the left and right sides of the protruding portion 62. An elastic water-stopping material 8B is provided on the back side of the protruding portion 62. The cover material 5 is a continuous through material in the flow direction, and is configured such that the left and right edges of a generally flat covering portion 51 covering the side edges 13, 13 of adjacent roof panels 1, 1 are folded back to the back side and further downward, and the lower ends are each folded up outward to provide engagement portions 52, 52. The left and right edges of the covering portion 51 of the cover material 5 are formed into a bulging arc shape. An elastic water-stopping material 8A is disposed on the back side of the covering portion 51.

[0031] As described above, the drainage member 6 has a raised portion 62 formed thereon, so that the lower retaining member 2 is positioned and the two members 6, 2 can be fixed together by driving a fastener 2b into a mounting hole 220 formed approximately in the center of the member. In the illustrated embodiment, as described above, an elastic water-stopping material 8B is arranged on the back side of the raised portion 62, so that even if rainwater from the drainage portion of the drainage member 6 runs down the fixing device 2b, the elastic water-stopping material 8B can prevent water from leaking onto the base 4. Then, the side edges 13, 13 of the left and right roof panels 1, 1 are attached to the attached lower retaining member 2 using the aforementioned operating procedure, and then the procedure for attaching the upper one member 3A and the upper other member 3B is also as already explained. In the illustrated embodiment, as shown in Figures 2(c) to (e), the upper one member 3A is attached to the belowwater side of the mounting hole 220 (the front side of the drawing) and the upper other member 3B is attached to the abovewater side of the mounting hole 220 (the rear side of the drawing). However, the upper end (the front end in the drawing) and the lower end (the rear end in the drawing) of the fixing part 22 in the flow direction are each formed with claw-shaped protrusions 221, 221 formed by raising the notches, thereby preventing the fixing part 22 from falling off in the flow direction.

[0032] Thereafter, the cover material 5 is brought in from above and pressed from above so as to engage with the engaging portions 33, 33 of the upper one member 3A and the upper other member 3B, thereby elastically engaging the engaging portions 52, 52 and attaching them to form a substantially flat exterior surface. That is, the covering portion 51 of the covering material 5 and the face plate portion 11 of the roofing material 1 are continuous and flush with each other to form a substantially flat exterior surface.

[0033] Fig. 2(f) shows a state in which the upper other member 3B is disposed on the lower holding member 2 disposed on the drainage member 6, while Fig. 2(g) shows a state in which both the upper one member 3A and the upper other member 3B are disposed. That is, Fig. 2(f) is a cross-sectional view looking from the mounting hole 220 to the above-water side, and Fig. 2(g) is a front view looking from the underwater end to the above-water side, so the upper other member 3B is shown by a dotted line.

[0034] Figure 3(a) is a side cross-sectional view of the constructed vertical roof structure, and Figure 3(b) shows its front view. In order to clearly show the installation state of the upper other member 3B, the right side of the figure shows the cross-sectional configuration along the dashed dotted line shown in Figure 3(a). The base 4 in the figure is constructed by laying a sheathing board 4B made of a cement-excelsium board or the like on a square timber (main frame) 4A arranged in the flow direction, and further laying an asphalt roofing 4c on top of that. On the base 4, insulating materials 7 having a rectangular cross section are arranged at appropriate intervals, and the drainage members 6 and the lower holding members 2 are arranged at the intervals between the insulating materials 7,7.

[0035] The construction of the vertical roof structure of the illustrated embodiment, which is made up of these components, is carried out in the following manner. First, the insulation material 7 is laid on the base 4 at predetermined intervals, the drainage members 6 are arranged at adjacent intervals, and the lower retaining members 2 are arranged so as to span the raised portions 62, and fixed to the base 4 with fasteners 2b. Next, the roof panel 1 is placed on the insulation material 7, and the edge of its face panel portion 11 and the descending step portion 12 are placed on the support portion 25 of the lower retaining member 2, and its side edge portion 13 is placed on the support portion 24. In the illustrated embodiment, the support portion 24 is in the shape of a surrounding dish that is open at the top, so that the side edge portion 13 of the roof panel 1 can be stably held in an engaged state, as already explained.

[0036] Subsequently, the engaging portions 33 of the upper one member 3A and the upper other member 3B are attached to the attachment portions 23 of the lower holding member 2. As for the attachment of the upper one member 3A and the upper other member 3B to the attachment portion 23, as already explained, the pushing portions 32a, 32b, which do not have the covering portions 31a, 31b, can be easily engaged with the attachment portion 23 by bringing them close to the upper end of the attachment portion 23 and rotating them. In the illustrated embodiment, the underwater end of the upper one member 3A is engaged with the convex portion 221 on the underwater side of the lower holding member 2, and the abovewater end of the upper other member 3B is engaged with the convex portion 221 on the abovewater side of the lower holding member 2, thereby preventing them from falling off in the flow direction.

[0037] Thereafter, the cover material 5 is placed from above and pressed from above so as to engage with the engaging portions 33 (locking pieces 332) of the upper one member 3A and the upper other member 3B, thereby elastically engaging and attaching the engaging portions 52 to form a substantially flat exterior surface. In the illustrated embodiment, an elastic water-stopping material 8A is arranged on the back side of the covering portion 51 of the cover material 5, so that the elastic water-stopping material 8A can prevent further penetration of rainwater that attempts to infiltrate from the tip side of the covering portion 51.

[0038] The vertically-roofed structure of the illustrated embodiment, which is composed of the above-mentioned members, is obtained by a construction method in which the side edges 13, 13 of the vertically-roofed panels 1, 1 are clamped by a pair of left and right upper holding members 3A and lower holding members 3B. Only one of the adjacent vertically-roofed panels 1, 1 on the left and right is held by the upper one member 3A, and only the other vertically-roofed panel 1 is held by the upper other member 3B. Since neither the upper one member 3A nor the upper other member 3B is provided on the side opposite to the side where the covering portions 31a, 31b are formed, the structure can be easily attached to the mounting portion 23 of the lower holding member 2, thereby providing strong holding action and reliable waterproofing.

[0039] In particular, the upper one member 3A and the upper other member 3B can be attached in an inclined manner with one cover portion 31a and the other cover portion 31b facing upward, and can be easily engaged in a rotational manner with the attachment portion 23. In other words, they can be easily engaged by facing close to the upper end of the attachment portion 23 with the pressing portions 32a, 32b facing downward and rotating them. For example, even if the upper one member 3A and the upper other member 3B are members smaller than a dozen centimeters, the upper one member 3A and the upper other member 3B can be easily attached without any difficulty in attachment.
