Also in this case, the rear portion of the rafter member 4 can be moved on the lower piece 23 in the shift direction by removing the fastening screw on the rafter 2 side of the bracket 26. Between the upper side of the roofing material 6 and the upper piece 21, a tip-type ridge-side upper seal member 27 is interposed, and between the lower side of the roofing material 6 and the intermediate piece 22, a retrofitting type. A ridge-side lower seal member 28 is interposed.
[0017]
As shown in FIG. 3 and FIG. 4, each rafter member 4 is a rafter body 32 having a hollow shape with a substantially square cross section, and a roofing presser having a “T” cross section formed on the upper side of the rafter body 32. It is formed integrally with the part 31. Between the roofing material retainer 31 and the rafter body 32, a pair of symmetrical groove portions 33, 33 that are partitioned by the partition wall 37 of the roofing material retainer 31 are formed. However, although not shown, the rafter member 4 at the left and right end portions has a shape having a single groove portion 33.
[0018]
Further, an upper seal member 34 and a lower seal member 35 are provided in each sunk groove portion 33 with the roofing material 6 interposed therebetween. The upper seal member 34 is a tip-attached type attached to the roofing material pressing portion 31 on the lower surface of the outer end portion, and the lower seal member 35 is inserted between the roofing material 6 and the rafter body 32. It is a retrofit type to be installed. The edge of the roofing material 6 is inserted into the insertion groove 33 from the opening end 33a, and the edge of the roofing material 6 rattles against the rafter member 4 by the upper sealing member 34 and the lower sealing member 35. There is no watertightness.
[0019]
In such a configuration, the rafter member 4, the roofing material 6, the rafter member 4, and the roofing material 6 are assembled in the order of the rafter member 4, the roofing material 6, and the roofing material 6 with respect to the front frame 3 and the rafters 2 positioned at the front and rear. By attaching the last lower seal portion 35, the balcony roof 1 is assembled by work from the lower side.
[0020]
Here, when the roofing material 6 needs to be replaced due to breakage or the like after the construction of the balcony roof 1 described above, up to the damaged roofing material 6, the balcony is operated in the reverse order of the above assembly work. It becomes necessary to disassemble the roof 1. Therefore, in the present embodiment, the following structure is adopted so that the above-described disassembly work can be saved as much as possible.
[0021]
As shown in FIG. 3, in this embodiment, the depth dimension from the lower edge 33 b of the opening end 33 a of the insertion groove 33 to the partition wall 37 is “L”, and the partition wall from the edge 6 a of the roofing material 6 is formed. When the length dimension up to 37 is “A”, the lengths of the rafter groove portion 33 and the roofing material 6 of the rafter member 4 are set so as to satisfy the relationship of 4A> 2a, that is, 4A> 2 (LA). Designed.
[0022]
In this configuration, for example, when one roofing material 6A is broken as shown in FIG. 5A, first, the roofing material 6A and the roofing material 6B adjacent to the roofing material 6B, The seal member 35 is removed. Depending on the breakage of the roofing material 6A, the roofing material 6A is removed at this point (see FIG. 5B). Next, the roofing materials 6B and 6B adjacent to both sides are slid in the grooving groove portion 33 and moved to the outside as much as possible. That is, the roofing materials 6B and 6B on both sides are moved to a position where they abut against the partition wall 37 (see FIG. 3C).
[0023]
Here, with respect to the front frame 3 and the rafter 2, the two rafter members 4, 4 located on both sides of the damaged roofing material 6 </ b> A are unfastened and each slides outward (see FIG. 4D). . At this time, the roofing material 6A may be removed. In this way, when the two rafter members 4 and 4 are slid outward as much as possible, the above-mentioned relationship of A> 1 / 3L, a space that is widely opened between the rafter members 4 and 4, strictly speaking, The distance between both open ends 33 a of the rafter members 4, 4 is equal to or greater than the width of the roofing material 6.
[0024]
Therefore, a new roofing material 6C is arranged in the space between the two rafter members 4 and 4, and both edges of the roofing material 6C are swallowed so that the space between the two rafter members 4 and 4 is the original. Slide to the position (see (e) of the figure). Finally, both the rafter members 4 and 4 are fastened to the front frame 3 and the rafter 2 and a total of six lower seal members 35 are mounted again (see FIG. 8F).
[0025]
On the other hand, by satisfying the relationship of A> 1 / 3L, the insertion length of the edge portion of the roofing material 6 is considerably shortened as compared with the depth L of the penetration groove portion 33. For this reason, when the roofing material 6 is inserted into the rafter groove portion 33 of the rafter member 4, the roofing material 6 may be installed in a state of being extremely close to one side (in FIG. 5C). Like state). Therefore, in the present embodiment, the following configuration is adopted.
[0026]
That is, as shown in FIG. 3, the rafter groove portion 33 of the rafter member 4 is positioned between the partition wall 37 serving as the groove bottom of the rafter groove portion and the lower seal member 35. A position restricting portion 40 that protrudes lower than the upper end is formed. The position restricting portion 40 restricts the position of the edge of the roofing material 6 inserted prior to the mounting of the lower seal member 35, and the roofing material 6 seated on the mounting portion of the lower seal member 35 is So that it does not bias to the left or right.
[0027]
In this way, by providing the position restricting portion 40 on each rafter member 4, positioning work can be performed such that the end portion 6 a of the roofing material 6 is abutted against the position restricting portion 40. And the roofing material 6 can be easily centered. Therefore, even when the relationship of A> 1 / 3L is satisfied as described above, it is possible to reliably prevent the roofing material 6 from falling off the rafter member 4 due to wind or the like after construction.
[0028]
The present invention is not limited to the above-described embodiment. For example, as shown in FIG. 6, the position restricting portion 40 of the rafter member 4 is inserted into the rafter main body 32 from the upper surface in parallel to the partition wall 37. You may comprise with the vertical piece 41 which protrudes in 33. FIG. Further, as shown in FIG. 7, the position restricting portion 40 of the rafter member 4 is constituted by a horizontal T-shaped piece 42 extending in a horizontal “T” shape from the substantially middle position of the partition wall 37 toward the opening end 33 a. Also good. Further, as shown in FIG. 8, the position restricting portion 40 of the rafter member 4 may be configured by a butting portion formed by bending the partition wall 37 into a crank shape. Furthermore, as shown in FIG. 9, the position restricting portion 40 of the rafter member 4 </ b> C may be configured by a setting block 44 that is installed in the depth of the groove portion 33.
[0029]
In addition, although the rafter member of this embodiment integrally forms the rafter body and the roof gutter pressing portion, the present invention can also be applied to rafters in which they are formed separately.
[0030]
