Embodiments for Carrying out the Invention

[0009] Hereinafter, an embodiment of the present invention will be described with reference to Figs. 1 to 11. The roof structure 1 in this embodiment is used for the building 3.

[0010] In the building 3, a plurality of column members 15 are erected, and a ceiling side beam 17 is stretched between the upper ends of the adjacent column members 15.

[0011] The column member 15 and the ceiling side beam 17 are connected via an angle member 12. The angle member 12 is fixed to the column member 15 by a fixing bolt 14 passing through the angle member 12 and being screwed into a nut (not shown) disposed in the groove 16 of the column member 15, and the fixing bolt 16 passes through the angle member 14 and is screwed into the ceiling side beam 17 to be fixed to the ceiling side beam 17.

[0012] As shown in Fig. 5, a ceiling hanging fitting 23 is engaged with the ceiling side beam 17, and a ceiling board 25 is fixed to the lower end of the ceiling hanging fitting 23 in Fig. 5.

[0013] The above building 3 is equipped with a sash panel 31, a double-hung window panel 33, and a door panel 35. The sash panel 31 is made by fitting a plate material 39 inside a rectangular sash frame 37. The double-hung window panel 33 is made by installing a fixed panel 41 on the upper side and a movable panel 43 on the lower side inside a rectangular sash frame 40. The door panel 35 is made by installing a wall 45 on the right side inside the rectangular sash frame 37 in Figure 4, and installing a door 45 on the left side so as to be rotatable relative to the wall 45.

[0014] As shown in Figure 5, a fascia board 51 is installed on the right side of building 3 in Figure 5, above the column member 15. The fascia board 51 is fixed by screwing fixing screws 53 through the fascia board 51 and screwing them into the column member 15 and the ceiling beam 17. Also, as shown in Figure 6, a fascia board 55 is similarly installed on the left side of building 3 in Figure 6. Furthermore, as shown in Figure 7(a), a fascia board 57 is similarly installed on the left side of building 3 in Figure 7(a), and as shown in Figure 8(b), a fascia board 59 is similarly installed on the right side of building 3 in Figure 8(b).

[0015] As shown in Figures 4, 7, and 8, a bracket 61 is fixed to the upper side of the column member 15, and a roof support member 63 is fixed to the upper side of the bracket 61. The height of the column member 15 is set to increase from left to right in Figure 4, the upper part of the bracket 61 is inclined, and the roof support member 63 is installed in an inclined state so that the right side in Figure 4 is higher. The upper ends of the above-mentioned fascia boards 57 and 59 are fixed to the roof support beam 63.

[0016] A roof 65 is installed above the roof support member 63 shown in Figure 4. The roof 65 described above is composed of roof structure 1. As shown in Figure 9, roof structure 1 is made up of connected roofing materials 67, 69, and 71. Roofing material 67 is positioned at one end of the roof 65 in the connection direction (right end in Figure 9), roofing material 71 is positioned at the other end of the roof 65 in the connection direction (left end in Figure 9), and one or more roofing materials 69 are positioned between roofing materials 67 and 71.

[0017] The roofing materials 67, 69, and 71 mentioned above are, for example, made of aluminum and are hollow components manufactured by extrusion molding. The roofing materials 67, 69, and 71 are members with extended end faces as shown in Figure 10, and have multiple hollow sections 73. Furthermore, the roofing materials 67, 69, and 71 are provided with T-shaped grooves 72 that open to the lower side in Figure 10. The roof 65 is fixed by passing bolts 74 through the brackets 61 and the roof support members 63 and screwing them into T-shaped nuts 76 inserted into the T-shaped grooves 72, as shown in Figure 7(b).

[0018] A water channel structure 75 is provided at one end of the roofing material 69 in the connection direction (right side in Figure 10). The above-mentioned water channel structure 75 consists of a first water channel 77, a second water channel 79, a first receiving-side engaging portion 81, and a second receiving-side engaging portion 83.

[0019] The first water channel 77 is a recess formed on one end of the roofing material 69 in the connection direction (right side in Figure 10) and has an opening on the upper side. The second water channel 79 is formed on the other end of the first water channel 77 in the connection direction (right side in Figure 10). The first receiving engagement portion 81 is formed on the other end of the first water channel 77 in the connection direction (left side in Figure 10), and the second receiving engagement portion 83 is formed on the other end of the second water channel 79 in the connection direction (left side in Figure 10).

[0020] The first receiving engagement portion 81 has a recess 85 that is located on the upper side of the other end (left side in Figure 10) in the connection direction of the first waterway 77 and opens on the one end (right side in Figure 10) in the connection direction. A partition wall 87 is located between the first waterway 77 and the second waterway 79 mentioned above. The second receiving engagement portion 83 has engagement protrusions 89 and 91 provided on one end (right side in Figure 10) in the connection direction at the center of the partition wall 87 in the height direction (up and down direction in Figure 10), and an engagement recess 93 which is the space between the protrusions 89 and 91 and opens on one end in the connection direction.

[0021] A plug-in structure 95 is provided on the other end of the roofing material 69 in the connection direction (left side in Figure 10). The above-mentioned insertion structure 95 consists of a first insertion engagement portion 97 and a second insertion engagement portion 99. The first insertion engagement portion 97 described above consists of an extension portion 101 that extends from the upper side of the other end in the connection direction (left side in Figure 10) to the tip side (left side in Figure 10), and an engagement projection 103 formed on the tip side (left side in Figure 10) of the extension portion 101. An engagement recess 105 is formed on the upper side of the engagement projection 103 in Figure 10.

[0022] The second insertion engagement portion 99 consists of a rotation-preventing projection 109 extending from the lower side in Figure 10 to the lower side in Figure 10 of the base end portion 107 of the first insertion engagement portion 97, an engagement projection 111 formed on the other end side in the connection direction (left side in Figure 10) from the base end of the rotation-preventing projection 109, an engagement recess 113 provided on the lower side in Figure 10 of the engagement projection 111 and opening on the other end side in the connection direction, and a recess 115 provided on one end side in the connection direction (right side in Figure 10) of the rotation-preventing projection 109. The upper rotation-preventing projection 109 is bent so that the recess 115 is formed on the one end side in the connection direction (right side in Figure 10) of its lower end, thereby forming the engagement recess 113 between the rotation-preventing projection 109 and the engagement projection 111. The tip surface of the engaging projection 111 (the left side in Figure 10) and the other end of the anti-rotation projection 109 in the connection direction (the left side in Figure 10) are aligned in the connection direction.

[0023] The two roof materials 69 are connected when the first insertion engagement portion 97 of the insertion structure portion 95 of one roof material 69 engages with the first receiving engagement portion 81 of the water channel structure portion 75 of the other roof material 69, and when the second insertion engagement portion 99 of the insertion structure portion 95 of one roof material 69 engages with the second receiving engagement portion 83 of the water channel structure portion 75 of the other roof material 69. At this time, the engagement projection 103 of the first insertion engagement portion 97 engages with the engagement recess 85 of the first receiving engagement portion 81, and the upper part of the engagement recess 85 engages with the upper engagement recess 105 of the engagement projection 103. Furthermore, the engaging projection 111 of the second insertion engagement portion 99 engages with the engaging recess 93 of the second receiving engagement portion 83, the lower engaging projection 91 of the engaging recess 93 of the second receiving engagement portion 83 engages with the engaging recess 115 of the second insertion engagement portion 99, and the upper engaging projection 89 of the engaging recess 93 of the second receiving engagement portion 83 engages with the upper side of the engaging projection 111 of the second insertion engagement portion 99. In addition, the anti-rotation projection 109 is inserted into the second waterway 79.

[0024] The height of the partition wall 87 of the roofing material 69 is set such that when the roofing materials 69 are connected, there is a gap 117 between it and the extension 101 of the first insertion engagement portion 97 of the connected roofing material 69. Furthermore, the presence of the engagement projection creates a gap 118 between the partition wall 87 of one roofing material 69 and the upper side of the second insertion engagement portion 99 of the other roofing material 69. In addition, a gap 119 is also created between the roofing material 69 and one end of the second waterway 79 in the connection direction. These gaps serve as clearances to prevent capillary action, preventing water from seeping between the roofing materials 69 due to capillary action from the end face side.

[0025] The connected roofing materials 69 can slide in the connecting direction while the first receiving engagement portion 81 and the first insertion engagement portion 97 and the second receiving engagement portion 83 and the second insertion engagement portion 99 are engaged, thereby absorbing errors that occur when constructing the roof 65.

[0026] Of the above-mentioned water channel structure 75 and insertion structure 95, only the insertion structure 95 is provided on the above-mentioned roofing material 67. Of the above-mentioned roofing material 71, only the water channel structure 75 is provided, along with the above-mentioned insert structure 95.

[0027] Furthermore, a water-stopping plate 121 is formed at one end of the roofing material 67 in the connection direction (right end in Figure 10), protruding upward in Figure 10. A water-stopping plate 121 is also formed at the other end of the roofing material 71 in the connection direction (left end in Figure 10), protruding upward in Figure 10. The water-stopping plates 121 prevent rainwater from falling from the roof 65 onto both ends in the width direction of the roof 65 (both ends in the left-right direction in Figure 1).

[0028] The roofing material 69 and the roofing material 67 are connected in the same way as the connection between the two roofing materials 69. Also, the roofing material 69 and the roofing material 71 are connected in the same way as the connection between the two roofing materials 69.

[0029] A gutter 123 is installed at the downward-sloping end of the roof 65 (left end in Figure 7(a)). An end cover 125 is installed at the upward-sloping end of the roof 65 (right end in Figure 8(b)) to prevent rainwater from entering from the upward-sloping end of the roof 65 (right end in Figure 8(b)). Furthermore, as shown in Figures 5 and 6, the upper ends of the fascia boards 51 and 55 are fixed to the roof 65 by passing bolts 127 through the fascia boards 51 and 55 and screwing them into T-shaped nuts 129 located in T-shaped grooves 72 of the roofing materials 67 and 71.

[0030] Next, the operation of this embodiment will be described. To construct the roof 65 according to roof structure 1 using roofing materials 67, 69, and 71, the work is carried out as follows. First, the roofing material 71 is installed. Next, the first receiving engagement portion 81 of the water channel structure portion 75 of the roofing material 71 is engaged with the first insertion engagement portion 97 of the insertion structure portion 95 of the roofing material 69, and the second receiving engagement portion 83 of the water channel structure portion 75 of the roofing material 71 is engaged with the second insertion engagement portion 99 of the insertion structure portion 95 of the roofing material 69. At this time, the roofing material 69 is moved downward in Figure 10 so that the rotation-preventing projection 109 of the insertion structure 95 of the roofing material 69 is inserted into the second water channel 79 of the roofing material 71 from above in Figure 10, and then the roofing material 69 is moved to the other end side in the connection direction (left side in Figure 10) so that the first receiving engagement portion 81 of the roofing material 71 engages with the first insertion engagement portion 97 of the roofing material 69 and the second receiving engagement portion 83 of the roofing material 71 engages with the second insertion engagement portion 99 of the roofing material 69.

[0031] The roofing materials 69 are connected to each other in the same manner, and the roofing materials 69 and 67 are connected in the same manner. The roofing materials 67, 69, and 71 are connected by engaging portions provided at two locations that are spaced apart in the connection direction and also spaced apart in a direction perpendicular to the connection direction, thus ensuring a stable connection. Furthermore, the anti-rotation projection 109 abuts against the second water channel 79 of the other roofing members 71 and 69, preventing rotation of the roofing materials 67, 69, and 71 around the connection point, which also ensures a stable connection of the roofing materials 67, 69, and 71.

[0032] Since the roofing materials 67, 69, and 71 are slidable in the connection direction while connected, this allows for adjustments to errors in the fixing points of the roofing materials 67, 69, and 71. Water entering the first receiving engagement portion 81 and the first insertion engagement portion 97 from the upper side in Figure 10 is drained through the first water channel 77. Furthermore, if water overflows from the first water channel 77 beyond the partition wall 87, it is drained through the second water channel 79. A gap is provided in the connecting portion of the roofing materials 67, 69, and 71 as a clearance to prevent capillary action, thereby preventing water from seeping in through the end face of the connecting portion due to capillary action. Even if water seeps in through the end faces of the first receiving engagement portion 81 and the first insertion engagement portion 97, and the second receiving engagement portion 83 and the second insertion engagement portion 99 due to capillary action, the water is drained through the first water channel 77 and the second water channel 79.

[0033] Next, the effects of this embodiment will be described. The roof structure 1 has a first water channel 77 and a second water channel 79 arranged continuously in the connection direction on one end of the roof materials 67, 69, and 71, with a first receiving engagement part 81 on the first water channel 77 side and a second receiving engagement part 83 on the second water channel 79 side, and a first insertion engagement part 97 corresponding to the first receiving engagement part 81 and a second insertion engagement part 99 corresponding to the second receiving engagement part 83 on the other end in the connection direction, so that the roof materials 69 can be connected to each other, to each other and to each other, or to each other and to each other. This results in a simple configuration and effective drainage using the first water channel 77 and the second water channel 79. In addition, stable construction can be carried out by the engagement parts located at two locations spaced apart in the connection direction and in a direction perpendicular to the connection direction. Furthermore, since the anti-rotation projection 109 is provided, it can contact the second water channel 79 of the other roof members 71 and 69, thereby preventing rotation around the connecting portion of the roof members 67, 69, and 71, and making construction work easier. Also, with this configuration, since the anti-rotation projection 109 is positioned inside the second water channel 79, the space inside the roof members 67 and 69 can be effectively utilized.

[0034] Furthermore, the roofing materials 67, 69, and 71 can slide in the connection direction while connected, which allows for the absorption of errors in the fixing points of the roofing materials 67, 69, and 71, making installation work easier. Furthermore, since the roofing materials 67, 69, and 71 are integral components formed by aluminum extrusion molding, their structure is simple and easy to manufacture. Furthermore, since gaps are provided in the connecting portions of the roofing materials 67, 69, and 71 as clearances to prevent capillary action, water infiltration due to capillary action from the end faces of the connecting portions can be prevented.

[0035] Furthermore, the present invention is not limited to the above-described embodiment. The size of the roofing material, the number and shape of the hollow sections, and the number of connected sections are not limited to those shown in the illustration, and various configurations are possible. [Industrial applicability]

[0036] The present invention relates, for example, to a roof structure, and more particularly to one that can effectively prevent water from entering the interior of a building with a simple configuration and is easy to install, and is suitable for residential buildings, for example.
