Description

  The present invention relates to a roof. More specifically, for example, among rainproof, snowproof, and windproof roofs installed in outdoor passages, the roof having a portion where roof materials are connected in a valley shape, such as a roof installed at a corner of a passage. .

  A roof may be installed in an outdoor passage to prevent rain, snow and wind. Some roofs use a polycarbonate plate as a roofing material (for example, Patent Document 1).

The conventional roof shown in FIG. 12 is a roof installed in an outdoor passage, and has a straight roof unit SU1 installed at a straight portion of the passage and a corner roof unit CU1 installed at a corner of the passage. The two straight roof units SU1 are connected by the corner roof unit CU1, thereby forming an L-shaped roof in plan view.
The straight roof unit SU1 includes a pair of cross beams 120, 120 supported by a support 110, a pair of cross beams 120, 120 spanned between ends of the pair of cross beams 120, 120, and a pair of cross beams 120, 120. A roofing material 140 made of a polycarbonate plate inserted in a frame constituted by a plurality of roof connecting beams 131 spanned, two adjacent roof connecting beams 131, 131 and a pair of cross beams 120, 120. It consists of and. The roof connecting beam 131 is formed into an arch shape that is convex upward in a side view, and the roof material 140 is also an arch shape that is convex upward in a side view along the roof connecting beam 131. .

  On the other hand, as shown in FIG. 13A, the corner roof unit CU1 has a pair of inner girders 121, 121 and a pair of outer girders 122, 122 supported by a column 110 (see FIG. 12). The pair of inner girders 121 and 121 are connected in an L shape in plan view to form an entrance corner I of the passage, and the pair of outer girders 122 and 122 are connected in an L shape in plan view to form an exit corner O of the passage. Yes. Further, a corner beam 150 is bridged diagonally between an entrance corner I formed by the inner girders 121 and 121 and an exit corner O formed by the outer girders 122 and 122. A plurality of roof connecting beams 131 are bridged between the corner beam 150 and the outer girders 122 and 122 so as to go straight to the outer girders 122 and 122. A roof material 140 made of a polycarbonate plate is inserted into a frame constituted by these inner girders 121, outer girders 122, roof connecting beams 131, and corner beams 150. The roof connecting beam 131 and the corner beam 150 are formed in an arch shape that is convex upward in a side view, and the roof material 140 is also convex upward in the side view along the roof connecting beam 131 and the corner beam 150. An arch shape is formed (see FIG. 13B).

In the corner roof unit CU <b> 1, the roof material 140 connected to one outer girder 122 and the roof material 140 connected to the other outer girder 122 are connected to each other via a corner beam 150. Here, since the roof material 140 has an arch shape, the roof materials 140 and 140 are connected horizontally in the vicinity of the center of the corner beam 150, and the roof material 140 is located on the protruding corner O side from the center of the corner beam 150. 140 are connected in a mountain shape, and the roof materials 140 and 140 are connected in a valley shape from the center of the corner beam 150 to the corner I side (see FIG. 13C).

Therefore, a bottomed depression is formed by the roof connection beam 131, the corner beam 150, and the roof material 140 at a portion where the roof connection beam 131 and the corner beam 150 are connected to the corner I 150 from the center of the corner beam 150. The

Therefore, when it rains on the conventional roof, there is a problem that rainwater W accumulates in the depression.
Further, there is a problem that the roof material 140 is soiled by the accumulated rainwater W or rainwater oozes under the roof.

  In the conventional roof described above, if the roof connecting beam 131 is eliminated, the depression is eliminated, so that the above problem seems to be solved. However, since the roof material 140 made of polycarbonate is weak, it is not practical to eliminate the roof connecting beam 131 that supports the roof material 140.

Some roofs installed in outdoor passages and the like use an aluminum extruded profile as a roofing material.
The square roof unit CU2 shown in FIG. 14 (A) uses an aluminum extruded roof material 240 in place of the polycarbonate roof material 140 in the square roof unit CU1, and the roof connecting beam 131 is eliminated. Yes. The roof material 240 is formed into an arch shape that is convex upward in a side view. The rest of the configuration is the same as that of the corner roof unit CU1.
As shown in FIG. 14 (B), the roof material 240 has one side edge bent upward from the side edges adjacent to the other roof material 240, and an inverted L-shaped L-shaped rib 241a is formed. ing. The other side edge is also bent upward, and an inverted J-shaped J-shaped rib 241b is formed. The two adjacent roof materials 240 and 240 are connected such that the L-shaped rib 241a of one roof material 240 is included in the J-shaped rib 241b of the other roof material 240. By connecting a plurality of roofing materials 240 in this way, a plurality of ribs 241 are formed as a whole.
Here, the ribs 241a and 241b are provided on the roof material 240 not only for connecting the adjacent roof materials 240 and 240 but also for maintaining the strength as the roof material 240. This is because the roof installed in the outdoor passage must withstand the wind pressure and withstand the load of snow.

Also in the corner roof unit CU <b> 2, the roof material 240 connected to one outer girder 122 and the roof material 240 connected to the other outer girder 122 are connected to each other via a corner beam 150. Here, since the roof material 240 has an arch shape, the roof materials 240 and 240 are connected horizontally in the vicinity of the center of the corner beam 150, and the roof material 240 is located on the protruding corner O side from the center of the corner beam 150. 240 are connected in a mountain shape, and the roof materials 240 and 240 are connected in a valley shape on the corner I side from the center of the corner beam 150.
Since the rib 241 protrudes upward in the roofing material 240, the rib 241, the corner beam 150, and the roof are provided at a portion where the rib 241 and the corner beam 150 are connected to the corner I 150 from the center of the corner beam 150. A bottomed depression is formed from the material 240.
The interval between the ribs 241 is narrower than the interval between the roof connecting beams 131 in the corner roof unit CU1, and the height of the rib 241 is higher than the height at which the roof connecting beams 131 protrude from the roof material 140 in the corner roof unit CU1. high. Therefore, the corner roof unit CU2 has a larger number of depressions and a larger area than the corner roof unit CU1.

Therefore, even when the aluminum extruded profile roofing material 240 is used, there is a problem that rainwater W accumulates in the depression when it rains on the roof.
In addition, there is a problem that the roof material 240 is soiled by the accumulated rainwater W, or rainwater oozes under the roof.

The water can be drained to the flange 52 through the gap between the flange 52.

  Moreover, since the corner beam 50 has the strength portion 51, the roof material 40 can be supported even when a load due to wind pressure or snow is applied to the roof material 40. Therefore, it can withstand wind pressure and withstand the load caused by snow.

  Moreover, the connection part of the roof material 40 and the corner beam 50 is hidden by the buttock cover 57, and the appearance is good. Moreover, since the roof material 40 is fixed to the roof material fixing surface 52f located above the collar portion 52, the collar portion 52 is hidden by the roof material 40, and the appearance is good. Moreover, since the collar part 52 is integrally formed on the upper surface of the strength part 51, the collar part 52 cannot be seen from the bottom surface of the roof A, and the appearance when the roof A is looked up from the bottom is improved.

By the way, as shown in FIG. 7, one end of the flange portion 52 is located on the entrance corner I side, and is open above the inner girder 21. Therefore, the rainwater that has flowed through the collar 52 is drained to the inner ridge 63 (FIG. 7A). Similarly, the other end of the collar portion 52 is located on the protruding corner O side, and is opened above the outer girder 22. Therefore, the rainwater that has flowed through the heel portion 52 is drained to the outer side ridge 64 (FIG. 7B).
In FIG. 7, the cover part end cap attached to the end part of the cover part 57 and the roof material side cover attached to the end part of the roof material 40 are omitted.

  As described above, the inner ledge 63 and the outer ledge 64 are connected to the ledge 61 of the straight roof unit SU connected to the square roof unit CU, and the ledge 61 is connected to the ledge 62 attached to the column 10. . Therefore, the waste water that has flowed through the flange portion 52 can flow to the flanges 61, 62, 63, and 64 and be guided to the outside of the roof A. Therefore, rainwater does not exude under the roof A.
