Description

[Technical Field]

[0001] The present invention relates to a connecting member, a gutter system, and a method for installing a gutter system. [Background technology]

[0002] Eaves gutters, which are installed in buildings as drainage members, are connected in the longitudinal direction by connecting members. The eaves gutters are also held suspended from above by hanging fixtures installed at the eaves edge. For example, a hanging fixture for eaves gutters has been disclosed that includes a first mounting portion for mounting along the upper surface of a rafter and a hanging portion for mounting the eaves gutters (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 6603148 Summary of the Invention [Problem to be solved by the invention]

[0004] Construction materials are required to be easy to install. The conventional eaves gutter structure described above has the problem of requiring a lot of work because it is necessary to install the hanging fixtures for attaching the eaves gutter to the eaves edge and the connecting members for connecting the eaves gutter to each other during construction work.

[0005] The present invention has been made in consideration of the above-mentioned circumstances, and has an object to provide a connection member that is highly installable and reduces the number of steps required for installation. [Means for solving the problem]

[0006] In order to solve the above problems, the present invention proposes the following means. The connecting member according to the present invention comprises a main body that connects two eaves gutters, and a top-mounted fitting that is attached to the main body and holds the main body to a building.

[0007] According to this invention, the main body connecting the two eaves gutters is held to the building by a top-mounted fitting. In other words, the main body for connecting the eaves gutters and the top-mounted fitting, which is a hanging device for attaching the eaves gutters to the building, are molded as a single unit. This makes it possible to integrate the functions of the hanging device and connecting member used when installing the eaves gutters on a building. This allows the top-mounted fitting to be the only component installed on the building. In other words, the work of installing at least the main body on the building can be omitted. This results in a highly efficient connection component that reduces the number of steps required for installation.

[0008] The main body may be configured so that its attachment position relative to the top fitting is adjustable.

[0009] According to this invention, the attachment position of the main body relative to the top-mounted fitting is adjustable. Therefore, by adjusting the attachment position of the attachment part and the top-mounted fitting, the distance between the main body and the building can be adjusted horizontally. This makes it possible to adjust the position of the main body without changing the position of the top-mounted fitting installed on the building. This makes it easier to adjust the position of the main body.

[0010] In addition, the gutter system of the present invention comprises an eaves gutter and the connecting member, and a plurality of the connecting members are provided at intervals on a building, and the eaves gutters are connected by the connecting members.

[0011] According to the present invention, the eaves gutters are connected by the connecting member according to the present invention, which allows the construction of a rain gutter system in a building to be carried out easily and efficiently.

[0012] In addition, the construction method for the gutter system includes a first step of installing multiple top-mounted fittings of the connecting member at intervals on the building, a second step of adjusting the mounting positions of the top-mounted fittings and the main body, and a third step of connecting the eaves gutter to the main body.

[0013] According to this invention, after adjusting the attachment position between the top-mounted fitting installed on the building and the attachment part on the main body, the eaves gutter is connected to the main body. In other words, the work of attaching the connecting member to the building and the work of connecting to the eaves gutter can be performed as separate processes. This contributes to easier adjustment of the schedule related to the building construction process. Therefore, the construction of the gutter system can be carried out more efficiently. [Effects of the Invention]

[0014] According to the present invention, a connecting member with high construction efficiency can be provided, which reduces the number of steps required for construction. [Brief explanation of the drawings]

[0016] Hereinafter, a rain gutter system 100 according to one embodiment of the present invention will be described with reference to the drawings. The gutter system 100 has the role of transporting rainwater that falls on the roof of the building 1 and moving it to a drain or the like. As shown in FIG. 1, the gutter system 100 is installed horizontally near the roof of the building 1 (for example, under the eaves). The gutter system 100 comprises an eaves gutter 10 and a connecting member 20. Note that, hereinafter, when indicating the direction of each member, the longitudinal direction, height direction, and width direction may be referred to using the eaves gutter 10 and connecting member 20 when attached to the building 1 as the reference. Specifically, the direction along the direction in which rainwater flows in the eaves gutter 10 is referred to as the longitudinal direction, the vertical direction of the building 1 is referred to as the height direction, and the direction perpendicular to the longitudinal direction and height direction is referred to as the width direction.

[0017] The eaves gutter 10 transports rainwater horizontally. The eaves gutter 10 is a long, U-shaped member. As shown in FIG. 2, the eaves gutter 10 in this embodiment has a bead portion 10B at the connection between the bottom and side of the U-shape to ensure strength. The bead portion 10B is formed by providing an appropriate bend at the connection between the bottom and side of the U-shape or by adding a member to the inside of the U-shape. In addition, the edge on the opening side of the U-shape, i.e., the edge of the side of the U-shape that is not connected to the bottom, is provided with an edge portion 10E that ensures structural strength and also serves as a chamfer. The edge portion 10E is formed by bending the side of the U-shape of the eaves gutter 10.

[0018] The longitudinal length of the eaves gutter 10 is preferably, for example, 1800 mm or less, and more preferably 600 mm or less. The height dimension of the U-shape of the eaves gutter 10 shown in Figure 2 is preferably 150 mm or less. The width dimension of the U-shape is preferably 150 mm or less. The eaves gutter 10 is preferably manufactured by injection molding using a resin material.

[0019] The connecting member 20 connects the eaves gutters 10 in the longitudinal direction. In this way, the connecting member 20 has the role of enabling rainwater to be transported over long distances by the eaves gutters 10 connected in the longitudinal direction. The connecting member 20 includes a main body 21 and a top fitting 22. The main body 21 connects the ends of the eaves gutters 10 together. The main body 21 is a U-shaped member. The inner side and inner bottom surfaces of the U-shape of the main body 21 have shapes that correspond to the outer side and outer bottom surfaces of the eaves gutters 10, as shown in Figure 2. The eaves gutters 10 are inserted from the longitudinal direction into both longitudinal ends of the main body 21, which has such a shape. In this way, the two eaves gutters 10 are connected by the main body 21. In addition to the above-described shape, the main body 21 includes an attachment portion 21a and a grip portion 21b. The main body 21 is preferably manufactured by injection molding using a resin material.

[0020] The mounting portion 21a is a portion where the main body 21 is attached to the top-mounted fitting 22. The mounting portion 21a is provided in a direction perpendicular to the longitudinal direction of the main body 21. Both ends of the mounting portion 21a are connected to both inner side surfaces of the U-shaped main body 21. As shown in FIGS. 2 and 3 , the main body 21 and the top-mounted fitting 22 are preferably attached using, for example, a plurality of bolts B spaced apart. In other words, bolt holes Bh are preferably provided at equal intervals at the locations where the top-mounted fitting 22 and the mounting portion 21a come into contact when they are attached. This shape allows the mounting positions of the mounting portion 21a and the top-mounted fitting 22 to be adjusted. By appropriately shifting the positions of the bolt holes Bh when mounting, the mounting positions of the top-mounted fitting 22 and the mounting portion 21a can be adjusted. As shown in Figure 2, it is preferable that the mounting portion 21a is molded integrally with the main body portion 21, but as long as it is integrated when installed on the building 1, it may also be molded separately and assembled as appropriate.

[0021] The gripping portion 21b secures the eaves gutter 10 connected to the main body 21. As shown in FIG. 4, the gripping portion 21b is U-shaped, and both inner side surfaces of the U-shape are provided so as to contact both heightwise sides of the edge 10E of the eaves gutter 10. As shown in FIG. 2, the gripping portion 21b having such a shape is provided on the opening side edges of both side surfaces of the U-shape of the main body 21, at both longitudinal ends of the main body 21. The gripping portion 21b elastically deforms when the eaves gutter 10 is inserted into the main body 21, and grips the edge 10E of the eaves gutter 10 by pressing it down with a reaction force. In this way, the gripping portion 21b secures the main body 21 and the eaves gutter 10 together.

[0022] When the eaves gutter 10 is inserted into the main body 21, the outer surface and outer bottom surface of the eaves gutter 10 come into contact with the inner surface and inner bottom surface, respectively, of the main body 21. Alternatively, a rubber packing (not shown) may be provided between the main body 21 and the eaves gutter 10 to eliminate the gap between the gripping portion 21b and the eaves gutter 10. This may allow the main body 21 and the eaves gutter 10 to be more securely fixed together by friction with the rubber packing.

[0023] 5, the main body 21 connects the ends of the eaves gutter 10 together in the longitudinal direction. At this time, it is preferable that the insertion allowance of the eaves gutter 10 into the main body 21 is about 5 mm shorter than the amount of insertion of the eaves gutter 10 into the main body 21. This allows the main body 21 to absorb the amount of deformation, for example, when the eaves gutter 10 expands due to a rise in temperature in the building 1.

[0024] The top-mounted fitting 22 holds the main body 21 to the building 1. The top-mounted fitting 22 includes a fixing portion 22a, an installation portion 22b, and an intermediate portion 22c. The fixing portion 22a is a portion that comes into contact with the mounting portion 21a of the main body 21. As shown in Fig. 2, the fixing portion 22a has a U-shape. A plurality of holes are provided at intervals on the side surface of the U-shape of the fixing portion 22a to accommodate bolt fastening to the mounting portion 21a.

[0025] The installation portion 22b is the portion of the top-cast fitting 22 that is attached to the building 1. When installing the installation portion 22b of the top-cast fitting 22 to the building 1, it is preferable to install it on top of the rafters 2 on the roof of the building 1 as shown in Fig. 5 or on top of the sheathing board 3 as shown in Fig. 6. The intermediate portion 22c is a portion located between the fixed portion 22a and the construction portion 22b. In other words, the fixed portion 22a and the construction portion 22b are connected by this intermediate portion 22c. When the top-mounted fitting 22 is attached to the building 1, it is preferable that the intermediate portion 22c be perpendicular to the ground. In other words, the angle between the intermediate portion 22c and the construction portion 22b is preferably such that when the construction portion 22b is parallel to the portion where it is attached to the building 1 (the rafters 2 or the sheathing boards 3), the intermediate portion 22c is perpendicular to the ground.

[0026] Furthermore, it is preferable that the fixing portion 22a can grip the mounting portion 21a so that the mounting portion 21a is parallel to the ground when the top-mounting fitting 22 is attached to the building 1. The top-mounted fitting 22 is preferably formed by pressing a metal member to have the above-described configuration, for example.

[0027] The gutter system 100 according to this embodiment is configured by providing a plurality of connecting members 20 having the above-described configuration at intervals on the building 1, and connecting a plurality of eaves gutters 10 in the longitudinal direction in accordance with the positions of the connecting members 20. A construction method for the gutter system 100 on the building 1 will be described below with reference to Figs. 8 and 9.

[0028] (1st step) As shown in Figure 8, this is a process of installing multiple top-mounted fittings 22 of the connecting member 20 at intervals on the building 1. As mentioned above, the top-mounted fittings 22 are preferably attached to either the rafters 2 or the sheathing boards 3. During this process, the top-mounted fittings 22 are installed after appropriately selecting which of the above to install them on. Furthermore, in the first process, it is preferable that the top-mounted fittings 22 and the main body 21 are installed as a single unit.

[0029] (2nd process) This is a process for adjusting the attachment position of the top-mounted fitting 22 and the attachment portion 21a. When attaching the eaves gutter 10 to the building 1, it is necessary to provide a slope (drainage gradient) in the eaves gutter 10 for efficient drainage. When the rafters 2 or sheathing boards 3 are inclined relative to the ground, the height of the main body 21 of the connecting member 20 in the building 1 can be adjusted by moving the attachment positions of the attachment portion 22b of the top-mounted fitting 22 and the rafters 2 or sheathing boards 3 along the slope, as shown in FIG. 8 . Specifically, when the position of the main body 21 is to be raised, as in the connecting member 20 on the left in FIG. 8 , the attachment portion 22b is provided so that the entire attachment portion 22b is in contact with the sheathing board 3. On the other hand, when the position of the main body 21 is to be lowered, as in the connecting members 20 in the center and right in FIG. 8 , the attachment portion 22b is moved so that part of it protrudes from the sheathing board 3. This causes the main body 21 to move diagonally downward along the slope of the sheathing board 3.

[0030] After determining the height of the main body 21 in this way, the widthwise position of the main body 21 is adjusted as follows. That is, the positions of the bolt holes Bh provided in the top-mounting fitting 22 and the mounting portion 21a are shifted from each other when they are mounted. This moves the position of the main body 21 horizontally. In this way, the distance between the multiple main body parts 21 and the wall of the building 1 is made constant.

[0031] (3rd step) As shown in Figure 9, this is the process of connecting the eaves gutter 10 to the main body portion 21. Through the above-mentioned first and second steps, the main body portions 21 are arranged in a state in which multiple main body portions 21 are spaced apart and arranged at an angle along the wall of the building 1. With the main body portions 21 in this state, both longitudinal ends of the eaves gutter 10 are inserted into adjacent main body portions 21. Here, as mentioned above, in order to enable the main body portions 21 to absorb deformation of the eaves gutter 10, it is preferable to note that the insertion allowance of the eaves gutter 10 into the main body portion 21 should be about 5 mm shorter than the amount by which the eaves gutter 10 can be inserted into the main body portion 21. After completing the above steps, the roofing material 4 (if the top-casting fittings 22 are attached to the rafters 2, the sheathing boards 3 and the roofing material 4) are attached on top of the top-casting fittings 22, and the construction is completed.

[0032] As described above, according to the connecting member 20 of this embodiment, the main body 21 that connects the two eaves gutters 10 is held to the building 1 by the top-mounted fitting 22. In other words, the main body 21 for connecting the eaves gutters 10 together and the top-mounted fitting 22, which is a hanging tool for attaching the eaves gutters 10 to the building 1, are molded as a single unit. Therefore, the functions of the hanging tool used when installing the eaves gutters 10 on the building 1 and the connecting member 20 can be integrated. This allows the only component to be installed on the building 1 to be the top-mounted fitting 22. In other words, it is possible to omit the work of installing at least the main body 21 on the building 1. This allows for the connection member 20 to be highly installable, reducing the number of steps required for installation.

[0033] Furthermore, the attachment position of the main body 21 relative to the top-attachment fitting 22 is adjustable. Therefore, by adjusting the attachment position of the attachment part 21a and the top-attachment fitting 22, the distance between the main body 21 and the building 1 can be adjusted in the horizontal direction. This makes it possible to adjust the position of the main body 21 without changing the position of the top-attachment fitting 22 installed on the building 1. This makes it easier to adjust the position of the main body 21.

[0034] Furthermore, the eaves gutters 10 are connected by the connecting members 20 according to the present invention. This allows the construction of the rain gutter system 100 in the building 1 to be carried out easily and efficiently.

[0035] Furthermore, after adjusting the attachment position between the top fitting 22 installed on the building 1 and the attachment portion 21a of the main body 21, the eaves gutter 10 is connected to the main body 21. In other words, the work of installing the connecting member 20 on the building 1 and the work of connecting it to the eaves gutter 10 can be performed as separate processes. This contributes to easier adjustment of the schedule related to the construction process of the building 1. Therefore, the construction of the gutter system 100 can be carried out more efficiently.

[0036] The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, a mechanism for moving the position of the main body 21 in the vertical direction may be provided at the middle portion 22c of the top-attaching fitting 22. Furthermore, the bolt fixing holes provided in the mounting portion 21a or the fixing portion 22a may be elongated holes, which may be used to adjust the positions of the main body portion 21 and the top-mounted fitting 22 in a stepless manner.

[0037] In addition, within the scope of the spirit of the present invention, the components in the above-described embodiments may be replaced with well-known components as appropriate, and the above-described modifications may be combined as appropriate. [Explanation of symbols]
