Description

[Technical Field]

[0001] The present invention relates to a roof structure having a roof supported on columns. [Background technology]

[0002] Conventionally, roof structures such as carports have been known as roof structures with a roof supported by pillars. Some of these roof structures have a drainage structure that drains water passing through a downspout installed along the pillars to the outside via a member made up of a base material fixed below the downspout with a screw member and a cover material fitted to the base material so as to cover the screw member (see, for example, Patent Document 1). The base material of this drainage structure is fitted and positioned in a drainage opening that opens to the side below the downspout, and the cover material is fitted to the base material so that the water is drained from an opening formed in a predetermined direction.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2020-85739 Summary of the Invention [Problem to be solved by the invention]

[0004] The desired direction of drainage of water passing through a downspout for a roof structure may differ depending on the installation site. However, in the above-mentioned conventional roof structures, the direction of the opening formed by fitting a cover material to a base material is fixed, so it is necessary to prepare a base material and a cover material so that the opening faces in opposite directions. This makes management complicated, as it is necessary to confirm and prepare the base material and cover material that are suitable for the construction site. In addition, because the drainage path is formed by multiple components, there is also the issue of complicated construction, such as installing a sealant between the two to prevent water leakage.

[0005] The present invention was made in consideration of such problems, and its purpose is to provide a roof structure that is easy to manage and install, and that allows drainage in different directions even with a single member. [Means for solving the problem]

[0006] The main invention for achieving this object is a roof structure having a roof supported by pillars, which has a drainage member provided at the bottom of the pillar and which drains water passing through a vertical gutter section provided inside the pillar, the drainage member being formed from a single member with a hollow section inside, having an upper opening provided above the hollow section and communicating with the vertical gutter section, and a drainage outlet on either side in a cross direction that crosses the opposing direction facing the pillar and connects the hollow section to the outside, and which is characterized in that the drainage outlet can be attached to the pillar regardless of which side in the cross direction it is located on. Other features of the present invention will become apparent from the description of this specification and the accompanying drawings. [Effects of the Invention]

[0007] According to the present invention, it is possible to provide a roof structure in which the management and construction of components is easy and which allows drainage in different directions even with a single component. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0009] An embodiment of a roof structure of the present invention will be described with reference to the drawings. In this embodiment, a roof structure having a roof supported by pillars, which is used as, for example, a carport or a terrace roof, will be described as an example.

[0010] As shown in Figures 1 and 2, the roof structure 1 of this embodiment has a roof 2 covering the parking area S, two pillars 3 supporting the roof 2, beams 4 connected to the upper ends of each pillar 3, and horizontal gutter materials 5 fixed to the upper ends of the two pillars.

[0011] The roof 2 is in the form of a roughly rectangular panel, and is fixed under the beams 4 connected to the upper ends of the columns 3, and is installed at an angle so that the column 3 side is lower. In the following explanation, the longitudinal direction of the roof 2 is referred to as the X direction, and the lateral direction of the roof 2 is referred to as the Y direction. Whether each part of the roof structural body 1 or each member constituting the roof structural body 1 is in a standalone state, the explanation will be given by specifying the directions as the X direction and the Y direction when installed.

[0012] The two pillars 3 are erected at a distance from each other in the X direction, and one of the two pillars 3 is provided with a vertical gutter 3a through which rainwater and the like flows. Each pillar 3 has a pillar body 30 with a hollow portion 30a penetrating in the vertical direction, and cover materials 31, 32 fitted to the pillar body 30. The pillar body 30 and the cover materials 31, 32 are all extruded members with the vertical direction as the extrusion direction.

[0013] 3, the pillar main body 30 has a square tube portion 30b having a substantially rectangular cross section and forming a hollow portion 30a, and a pair of extension portions 30d extending toward the parking area S side along wall portions 30c of the square tube portion 30b that face each other in the X direction with the hollow portion 30a in between. That is, the pillar main body 30 has a groove portion 30e that is recessed in the up-down direction on the parking area S side of the hollow portion 30a toward the opposite side from the parking area S (hereinafter referred to as the anti-parking area side).

[0014] Each of the cover materials 31, 32 is attached to the parking area S side of the pillar main body 30 and has a plate-shaped cover main body 31a, 32a that covers the groove portion 30e, and locking portions 31b, 32b that are provided near both ends of the cover main bodies 31a, 32a in the X direction on the side opposite the parking area and that lock onto the wall portion 30c. One of the two cover materials 31, 32, cover material 31, is provided with a vertical spout portion 3a that is provided between the locking portions 31b and penetrates in the vertical direction. In other words, the cover material 31 is fitted to the pillar main body 30, thereby providing the vertical spout portion 3a on the pillar 3. In FIG. 1, the cover material 31 with the vertical spout portion 3a is attached to the left pillar 3 when viewed from the parking area S side.

[0015] As shown in Figure 2, a gutter member 5 having a gutter section 5a below the beam 4 is fixed to the top of the pillar 3. The gutter member 5 has approximately the same length as the roof 2. The end of the gutter member 5 on the parking area S side is fixed below the end of the roof 2 on the pillar 3 side, and has a recessed gutter section 5a below it into which water flows from the roof 2.

[0016] The horizontal gutter material 5 is provided with a communication member 6 at a location facing the pillar 3 with the vertical gutter portion 3a, which connects the inside of the gutter portion 5a with the inside of the vertical gutter portion 3a. Therefore, rainwater and the like that flows down the roof 2 into the gutter portion 5a flows into the vertical gutter portion 3a via the communication member 6.

[0017] A drainage member 7 disposed in the groove 30e is provided at the bottom of the pillar 3 equipped with the vertical gutter portion 3a. Therefore, the cover material 31 equipped with the vertical gutter portion 3a is provided between the horizontal gutter material 5 and the drainage member 7 so as to close the groove 30e.

[0018] The drainage member 7 is a resin molded product that is a single molded product, as shown in Fig. 4. Therefore, there are no gaps between the members as in parts that are made up of a combination of multiple members.

[0019] The drainage member 7 includes a pair of substantially rectangular surface plates 7a spaced apart in the Y direction, a connecting plate 7b connecting one end of the surface plates 7a in the X direction, a drainage passage 7d extending from the other end of the surface plates 7a in the X direction to form a drainage passage and having a drain outlet 7c at its tip, an upper plate 7e connecting the pair of surface plates 7a at both ends in the X direction near the top of the surface plates 7a, two upper fixing portions 7f extending upward from the opposing ends of the upper plate 7e, a downward extending portion 7g extending downward from the upper fixing portion 7f on the connecting plate 7b side, and a bottom plate 7h connecting the lower extending portion 7g to the lower end of the drainage passage 7d. A screw hole 7k is provided below the bottom plate 7h for screwing the lower portion of the drainage member 7 to the column body 30 via an attachment member 8.

[0020] The drainage member 7 has a hollow portion 7i formed between the pair of surface plate portions 7a and the top plate portion 7e and bottom plate portion 7h, and communicates with the outside via a drainage passage portion 7d. An upper opening 7j is formed above the hollow portion 7i, opening between the two fixed portions 7f. Therefore, the drainage member 7 communicates with the space above the upper opening 7j and the space outside the drain outlet 7c via the hollow portion 7i and the drainage passage portion 7d.

[0021] As shown in Figures 4(b) to 4(d), the drainage member 7 has a symmetrical shape from the center of the drainage member 7 in the Y direction on the parking area S side and the opposite parking area side. The width of the surface panel portion 7a in the X direction is approximately the same as the width of the pillar 3 in the X direction, and the width of the drainage member 7 in the Y direction is formed slightly narrower than the depth of the groove portion 30e of the pillar main body 30.

[0022] As shown in Fig. 5, the drainage member 7 is placed under the cover material 31, and with the downspout portion 3a positioned between the two upper fixing portions 7f, the upper fixing portions 7f are screwed to both sides of the downspout portion 3a to fix it to the cover material 31. When the drainage member 7 is fixed to the cover material 31, the downspout portion 3a is positioned within the upper opening 7j of the drainage member 7 in a plan view, as shown in Fig. 3(b). At this time, the lower end of the upper opening 7j may be positioned slightly below the upper plate portion 7e and may extend into the hollow portion 7i.

[0023] When attaching the cover material 31 to which the drainage member 7 is fixed to the column main body 30, as shown in FIG. 5, a pair of extension portions 30d corresponding to the positions where the drainage member 7 is to be disposed on the column main body 30 are cut away by the height of the drainage member 7 to form recesses 30f in advance. Then, the cover material 31 to which the drainage member 7 is fixed is fitted into the groove portion 30e from the parking area S side to form the column 3 with the downspout portion 3a. At this time, for more stable attachment, an attachment member 8 with an L-shaped cross section may be fixed with a screw to the threaded hole 7k below the drainage member 7, and after fitting the cover material 31 into the groove portion 30e, the attachment member 8 may be screwed to the column main body 30. Here, the Y direction corresponds to the facing direction in which the drainage member and the column face each other, and the X direction corresponds to the intersecting direction intersecting the facing direction.

[0024] When the cover material 31 and the drainage member 7 are attached, the opening at the upper end of the vertical gutter section 3a faces the opening at the lower end of the communication member 6 that communicates with the inside of the gutter section 5a. This allows communication from the gutter section 5a to the drainage passage section 7d of the drainage member 7, making it possible for rainwater and the like in the gutter section 5a to be discharged from the drainage outlet 7c.

[0025] The drainage member 7 attached to the pillar 3 is arranged so that the surface plate portion 7a on the parking area S side and the cover body 31a of the cover material 31 are approximately flush with each other, and the connecting plate portion 7e is arranged so that it is approximately flush with the wall portion 30c of the pillar body 30. The drainage member 7 attached to the pillar body 30 has the drainage passage portion 7d protruding to one side in the X direction of the pillar body 30. Since the drainage member 7 has a symmetrical shape on the parking area S side and the opposite parking area side from the center of the drainage member 7 in the Y direction, as shown in Figure 6, by flipping the parking area S side and the opposite parking area side and attaching them, it is possible to attach the drain outlet 7c facing either side in the X direction.

[0026] According to the roof structure 1 of this embodiment, the drainage member 7 provided at the lower part of the pillar 3 has an upper opening 7j provided above the hollow portion 7i inside and communicating with the vertical gutter portion 3a, and a drainage passage portion 7d having a drainage outlet 7c connecting the hollow portion 7i to the outside, so that water passing through the vertical gutter portion 3a can flow into the hollow portion 7i and the water that has flowed into the hollow portion 7i can be discharged to the outside through the drainage outlet 7c.

[0027] Furthermore, although the drain outlet 7c is provided on either side in the X direction, the drain member 7 can be attached to the column body 30 regardless of whether the drain outlet 7c is located on either side in the cross direction. Therefore, even a single drain member 7 can be attached to the column body 30 with the drain outlet 7c located on either side in the X direction. This eliminates the need to prepare two types of drain members with drain outlets 7c located on different sides, making management and installation of the drain member 7 easy. Furthermore, because the drain member 7 is formed from a single member, there are no gaps in the drainage path. This eliminates the need for sealing or other work, making installation easy.

[0028] In addition, since the drainage member 7 has a shape symmetrical with respect to the center in the Y direction, it is possible to maintain almost the same design no matter on which side in the X direction the drain outlet 7c is positioned and fixed to the pillar main body 30. Therefore, it also has excellent designability.

[0029] In addition, the drainage member 7 has a pair of upper fixing parts 7f at the top that are fixed to the vertical gutter section 3a, and are arranged opposite each other with a gap in the X direction across the upper opening 7j.Therefore, regardless of which side in the X direction the drainage outlet 7c is positioned on, it can be fixed to the column main body 30 via the vertical gutter section 3a by the pair of upper fixing parts 7f.

[0030] Furthermore, since the drainage member 7 is fixed to the pillar body 30 via the mounting member 8 fixed to the lower part, it is possible to prevent the drainage member 7 from being attached so that it floats on the parking area S side of the cover material 31, regardless of which side in the X direction the drain outlet 7c is located on. This results in an excellent design.

[0031] In addition, the drainage member 7 has a bottom plate portion 7h below the hollow portion 7i that forms an inclined surface that becomes lower toward the drainage outlet 7c, so that water that flows into the hollow portion 7i can be quickly discharged to the outside through the drainage outlet 7c.

[0032] In the above embodiment, an example has been described in which the lower part of the drainage member 7 is fixed to the column main body 30 by the mounting member 8, but the present invention is not limited to this. For example, as shown in Fig. 7, a pair of surface plate parts 7a may each have plate-shaped lower fixing parts 7l extending downward and facing each other in the Y direction, and one of the lower fixing parts 7l may be cut off to match the mounting direction of the drainage member 7, and the other lower fixing part 7l may be screwed to the column main body 30.

[0033] Furthermore, as shown in FIG. 8, by arranging the positions of the lower fixing portions 7l provided on the pair of surface plate portions 7a at different positions in the X direction, it becomes possible to fix the lower fixing portion 7l without cutting it out.

[0034] In the above embodiment, an example was described in which the direction of the drain outlet 7c is made different in the X direction by installing the parking area S side and the opposite parking area side upside down. However, for example, as shown in Figure 9, by connecting a flow path pipe 9, known as an elbow, to the drain passage section 7d, which changes the drain direction by 90 degrees, it is also possible to drain water toward the opposite parking area side.

[0035] The above-described embodiments are provided to facilitate understanding of the present invention and are not intended to limit the present invention. The present invention may be modified or improved without departing from the spirit thereof, and the present invention includes equivalents thereof. The present embodiment includes at least the following inventions.

[0036] Aspect 1: A roof structure having a roof supported by pillars, the roof structure having a drainage member provided at the bottom of the pillar for draining water passing through a vertical gutter provided inside the pillar, the drainage member being formed from a single member with a hollow portion inside, the drainage member having an upper opening provided above the hollow portion and communicating with the vertical gutter, and a drain outlet on either side in a cross direction that crosses the opposing direction facing the pillar and connects the hollow portion to the outside, the drain outlet being capable of being attached to the pillar regardless of which side in the cross direction the drain outlet is located on.

[0037] According to the roof structure of the first aspect, the drainage member attached to the lower part of the column has an upper opening above the hollow portion inside the column that communicates with the downspout and a drain outlet that connects the hollow portion to the outside. This allows water passing through the downspout to flow into the hollow portion and then be discharged to the outside through the drain outlet. The drain outlet is located on either side of the column in the cross direction, which intersects with the facing direction. However, the drainage member can be attached to the column regardless of whether the drain outlet is located on either side in the cross direction. Therefore, even a single drainage member can be attached to the column regardless of whether the drain outlet is located on either side in the cross direction. This eliminates the need to prepare two types of drainage members with drain outlets located on different sides, simplifying the management and installation of the drainage member. Furthermore, because the drainage member is formed from a single member, there are no gaps in the drainage path. This eliminates the need for sealing or other work, simplifying installation.

[0038] Aspect 2: The roof structure according to Aspect 1, wherein the drainage members are shaped symmetrically with respect to the center in the opposing direction.

[0039] According to the roof structure of the second aspect, the drainage members are symmetrical in shape with respect to the center in the opposing direction, so regardless of which side in the crossing direction the drain outlet is placed on and fixed to the pillar, it is possible to maintain a substantially uniform design. Therefore, it also has excellent designability.
