Description

[Technical Field]

[0001] The present invention relates to a reinforcement material and a gutter fixing structure. [Background technology]

[0002] When installing gutters (eaves gutters) on a building with a folded-plate roof, the roof and the gutters are sometimes secured together with suspension bolts. In this case, reinforcement materials are sometimes used to prevent the gutters from moving and the suspension bolts from deforming due to strong winds, etc. For example, a reinforcing material has been disclosed that has a structure in which a plate body and a fastener are fastened with a bolt to sandwich the plate body and the hanging bolt in a direction perpendicular to the axis (Patent Document 1). Also disclosed is a structure in which a suspension bolt is passed through a cylindrical body of a reinforcing material (anti-tip material) and fastened with a nut attached to the suspension bolt, thereby fixing the anti-tip material to the suspension bolt (Patent Document 2). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 4431596 [Patent Document 2] Japanese Patent Application Publication No. 08-253985 Summary of the Invention [Problem to be solved by the invention]

[0004] The reinforcing material described in Patent Document 1 requires that the suspension bolt be sandwiched between multiple members in the direction perpendicular to the axis and then secured with bolts. In addition, the structure described in Patent Document 2 requires that the reinforcing material be attached to the suspension bolt and secured with nuts. This poses the following problems: For example, the fastening work is required during the construction work, which increases the work time, and there is also a risk that the fastening parts may fall off during the construction work. In addition, the fixing force of the suspension bolts by the reinforcing material may vary depending on the tightening condition of the bolts. Furthermore, the fixing force by the bolts may loosen due to vibration, and sufficient fixing strength may not be obtained.

[0005] The present invention has been made in consideration of the above-mentioned circumstances, and has an object to provide a reinforcing material that can reliably reinforce a suspension bolt with fewer work steps. [Means for solving the problem]

[0006] In order to solve the above problems, the present invention proposes the following means. The reinforcing material of the present invention is a reinforcing material for a suspension bolt that secures a gutter to a corrugated roof, and comprises a main body portion, a contact portion that contacts the back surface of the corrugated roof and holds the main body portion and the corrugated roof together through friction, and a bolt fixing portion that is divided so as to be able to be integrated and that, when integrated, secures the suspension bolt to the main body portion so as to sandwich it, and at least a portion of the side that contacts the suspension bolt has a thread shape that matches the thread of the suspension bolt.

[0007] According to this invention, the bolt fixing portion has a thread shape that matches the thread of the hanging bolt on at least a portion of the side that contacts the hanging bolt. As a result, when the bolt fixing portion is separated, the thread shape of the bolt fixing portion is engaged with the thread of the hanging bolt, and then the bolt fixing portion is integrated. In this state, the contact portion is brought into contact with the back surface of the folded-plate roof, and the main body is held to the folded-plate roof.

[0008] In this state, when the suspension bolt is bent by wind or other force, the force transmitted from the suspension bolt to the bolt fixing part is transmitted to the folded plate roof via the contact part. In other words, the force applied to the suspension bolt is absorbed by the folded plate roof. Therefore, the suspension bolt can be reinforced by the reinforcing material.

[0009] In addition, the threads of the suspension bolts mesh with the threads of the bolt fixing parts. This prevents the suspension bolts and the bolt fixing parts of the reinforcement from shifting axially due to the force applied to the suspension bolts. Therefore, the force applied to the suspension bolts is reliably transmitted to the folded-plate roof, thereby reliably reinforcing the suspension bolts.

[0010] Furthermore, the reinforcing material and the suspension bolt are fixed by the bolt fixing portion so that the suspension bolt is sandwiched between them. Therefore, the reinforcing material can be easily and reliably fixed to the suspension bolt without any fastening work. Furthermore, since no fastening member is used, there is no risk of loosening due to vibration or the like, and the fixation can be stable. Therefore, the suspension bolt can be reinforced reliably with a small number of work steps.

[0011] The divided bolt fixing portions may be integrated by fitting together.

[0012] According to this invention, the bolt fixing portion is integrated by fitting, which means that the bolt fixing portion can be easily integrated, thereby making it easier to fix the reinforcing material to the suspension bolt.

[0013] The contact portion may also be provided with an attachment portion for attaching an extension member that fills the gap between the contact portion and the back surface of the corrugated roof.

[0014] According to this invention, the contact portion is provided with an attachment portion for attaching an extension member that fills the gap between the contact portion and the back surface of the folded-plate roof. In other words, the height position of the reinforcement can be adjusted by providing an extension member between the back surface of the folded-plate roof and the contact portion. In other words, a wide range of dimensions can be accommodated without using multiple types of reinforcement material.

[0015] One of the divided bolt fixing portions may have an arc shape of more than 180° in plan view.

[0016] According to this invention, one of the divided bolt fixing portions has an arc shape exceeding 180°. This allows the bolt fixing portion with an arc shape exceeding 180° to be attached to the suspension bolt alone. This makes it easy to temporarily fasten the divided bolt fixing portions before integrating them. This prevents components from falling off and allows for more stable work.

[0017] Furthermore, one of the divided bolt fixing portions may have projections at both ends of the arcuate shape.

[0018] According to this invention, one of the divided bolt fixing parts has a protrusion at each end of the arc-shaped part, so that when one of the bolt fixing parts is attached to the suspension bolt, the protrusion engages with the suspension bolt, thereby achieving more stable temporary fastening.

[0019] The outer surface of the contact portion may be arc-shaped.

[0020] The folded-plate roof to which the suspension bolts are attached may have a slope. In other words, the surface to which the suspension bolts are attached may not be parallel to the axial direction of the suspension bolts. In such cases, the suspension bolts may be intentionally bent before being attached. According to this invention, the outer surface of the contact portion is arc-shaped. This allows the contact portion to contact the folded-plate roof without changing the angle of the entire reinforcement member, even if the back surface of the folded-plate roof has a slope as described above. Therefore, it can flexibly respond to the slope of the back surface of the folded-plate roof.

[0021] In addition, the gutter fixing structure of the present invention is a gutter fixing structure that fixes a gutter to a corrugated roof, and includes a hanging bracket that suspends the gutter, a hanging bolt that connects the hanging bracket to the corrugated roof, and a reinforcing material that fixes the hanging bolt.

[0022] According to the present invention, a gutter fixing structure can be provided that can reliably reinforce the suspension bolts with fewer work steps. [Effects of the Invention]

[0023] According to the present invention, a reinforcing material can be provided that can reliably reinforce a suspension bolt with fewer work steps. [Brief explanation of the drawings]

[0025] Hereinafter, a reinforcement member 30 and a gutter fixing structure 100 according to one embodiment of the present invention will be described with reference to the drawings. The gutter fixing structure 100 shown in Fig. 1 is used to attach a gutter G to a folded-plate roof R of a building. For the gutter G according to this embodiment, for example, a single resin, a composite (multi-layer) resin, a metal, or a composite material in which a metal is coated with a resin is suitably used. The gutter fixing structure 100 comprises a hanging bracket 10, a hanging bolt 20, and a reinforcing material 30.

[0026] The hanging fitting 10 is a metal plate-like member that is hung on the edge of the rain gutter G and suspends the rain gutter G from the folded-plate roof R. As shown in FIG. 2 , the hanging fitting 10 includes a suspension portion 11, an enclosing portion 12, and an assembly portion 13. The suspension part 11 is connected to the suspension bolt 20, thereby serving to suspend the rain gutter G. As shown in FIG. 2, the suspension part 11 is positioned horizontally. Preferably, the suspension part 11 is formed by providing a resin material or the like around a metal plate. One end of the suspension part 11 is connected to the suspension part 11. The other end of the suspension part 11 is provided with an assembly part 13.

[0027] The surrounding portion 12 is a portion of the hanging bracket 10 that is located around the rain gutter G in a direction perpendicular to the longitudinal direction of the rain gutter G. The surrounding portion 12 is U-shaped as shown in FIG. 2, and one end of the U-shape is connected to one end of the suspension portion 11. The inner side of the U-shape is in contact with the outer surface of the rain gutter G.

[0028] The assembly part 13 connects the other end of the suspension part 11 to the other end of the surrounding part 12. The assembly part 13 is, for example, a ring-shaped member. The inner surface of this ring serves as a socket, which connects the other end of the suspension part 11 to the other end of the surrounding part 12. Specifically, the other end of the suspension part 11 and the other end of the surrounding part 12 are connected by inserting the other end of the suspension part 11 and the other end of the surrounding part 12 into this socket. This makes the hanging fitting 10 ring-shaped. By placing a rain gutter G inside this ring, it becomes possible to hang the rain gutter G using the hanging fitting 10.

[0029] The suspension bolt 20 is used to secure the rain gutter G to the folded-plate roof R. Specifically, as shown in FIG. 2, the upper end of the suspension bolt 20 is fastened to the folded-plate roof R. At this time, it is preferable that a roof washer Rw is provided on the folded-plate roof R, as shown in FIG. 2. Furthermore, as shown in FIG. 3, the lower end of the suspension bolt 20 is fastened to the suspension portion 11 of the suspension fitting 10 provided on the rain gutter G. At this time, it is preferable that a plate washer 11w is provided on the suspension portion 11, as shown in FIG. 3. With this structure, the suspension bolt 20 secures the folded-plate roof R and the rain gutter G in the vertical direction. The material, thickness, thread pitch, etc. of the suspension bolts 20 used in the suspension device are not particularly limited. It is preferable to determine the appropriate size and thickness taking into consideration the size and shape of the folded-plate roof R, the environment of the construction site (temperature, wind, etc. around the building where the gutter G is installed), etc.

[0030] The reinforcing material 30 is used to reinforce the suspension bolts 20. Here, as shown in FIGS. 1 and 2, in this embodiment, the distance from the fastening point between the suspension section 11 and the suspension bolts 20 to the fastening point between the folded-plate roof R and the suspension bolts 20 is approximately half the height of the folded-plate roof R. At this time, if the rain gutter G sways due to strong winds or the like, the shaking is applied to the suspension bolts 20 as a bending force. As a result, the suspension bolts 20 may be unable to withstand the force and bend. In order to prevent such shaking of the rain gutter G and deformation of the suspension bolts 20, the reinforcing material 30 is attached to the suspension bolts 20 as shown in FIGS. 1 and 2.

[0031] 4, the reinforcing member 30 includes a main body portion 31, a contact portion 32, and a bolt fixing portion 33. Furthermore, for example, resin or metal is preferably used for the reinforcing member 30. Alternatively, the main body portion 31 and the bolt fixing portion 33 may be made of different materials. The main body portion 31 is a portion of the reinforcing member 30 that particularly holds the suspension bolt 20. In this embodiment, the main body portion 31 is V-shaped. The contact portion 32 is the upper surface of the V-shape of the main body portion 31. The contact portion 32 contacts the back surface of the folded-plate roof R, thereby holding the main body portion 31 and the folded-plate roof R together through friction. In this embodiment, the contact portion 32 contacting the back surface of the folded-plate roof R includes cases other than direct contact between the contact portion 32 and the folded-plate roof R. For example, this also includes a case where an extension member 34 (described later) is disposed between the contact portion 32 and the back surface of the folded-plate roof R, and the contact portion 32 and the back surface of the folded-plate roof R are in contact with the extension member 34. In addition, the lower end of the main body portion 31 is fixed to the suspension bolt 20. As a result, when the reinforcing member 30 is attached to the suspension bolt 20 and the upper and lower ends of the suspension bolt 20 are appropriately tightened with nuts N, the suspension bolt 20 between the folded-plate roof R and the suspension portion 11 is held so as not to deform due to the bending force described above, as shown in FIG. 2 .

[0032] Furthermore, depending on the height of the folded-plate roof R, the height of the reinforcing material 30 may be insufficient, resulting in a gap between the folded-plate roof R and the contact portion 32. In this case, as shown in FIG. 5, the contact portion 32 may be provided with an extension member 34, which is a plate-shaped member for filling the gap from the contact portion 32 to the back surface of the folded-plate roof R. This makes it possible to accommodate a wide range of dimensions without providing multiple types of reinforcing material 30 according to the dimensions of the folded-plate roof R. In this case, it is preferable to provide an attachment portion (not shown) for attaching the extension member 34 to the contact portion 32.

[0033] Furthermore, the folded-plate roof R may be inclined in the vertical direction of the building to which the rain gutter G is attached. In this case, the suspension bolt 20 may be intentionally bent at the middle portion in the axial direction, as shown in Fig. 6. Furthermore, if the contact portion 32 of the reinforcing member 30 is flat with respect to the folded-plate roof R having this shape, the reinforcing member 30 will be attached at an angle in accordance with the slope of the folded-plate roof R. To prevent this and to install the reinforcing material 30 parallel to the vertical direction of the building, the outer surface of the contact portion 32 may be arc-shaped. This allows the main body portion 31 to be installed parallel to the vertical direction even when it comes into contact with a sloped folded-plate roof R, as shown in Figure 6.

[0034] The bolt fixing portion 33 has a shape for engaging and fixing the suspension bolt 20 and the main body portion 31 when attaching the reinforcing material 30 to the suspension bolt 20. In this embodiment, the bolt fixing portion 33 is provided in the center of the V-shaped valley portion of the reinforcing material 30, as shown in FIG. 4. The bolt fixing portion 33 includes a first bolt fixing portion 33a and a second bolt fixing portion 33b. In other words, in this embodiment, the bolt fixing portion 33 is divided into two parts that can be integrated.

[0035] The first bolt fixing portion 33a is a portion provided in a part of the main body 31 of the bolt fixing portion 33. Specifically, as described above, it is a portion provided in the center of the V-shaped valley of the main body 31. Also, as shown in FIG. 4, female fitting portions 33cf are provided on both sides of the first bolt fixing portion 33a. The female fitting portions 33cf have a socket-like shape corresponding to the male fitting portions 33cm (described later). The female fitting portions 33cf are through holes that penetrate the main body 31. In this embodiment, the female fitting portions 33cf are arranged at two positions in the vertical direction, on one side and the other side of the first bolt fixing portion 33a. Also, the female fitting portions 33cf have a rectangular shape that is long in the vertical direction.

[0036] The second bolt fixing portion 33b is a member provided separately from the main body 31 of the bolt fixing portion 33. As shown in FIG. 4, male fitting portions 33cm are provided on both sides of the second bolt fixing portion 33b. The male fitting portions 33cm are inserted into and fitted with the female fitting portions 33cf, thereby integrating the first bolt fixing portion 33a and the second bolt fixing portion 33b. The male fitting portions 33cm are plate-shaped and extend vertically. The male fitting portions 33cm protrude from the second bolt fixing portion 33b side toward the main body 31 side. The tip of the male fitting portion 33cm is provided with a retaining claw that prevents the male fitting portion 33cm from coming out of the female fitting portion 33cf after being inserted into it.

[0037] The reinforcing member 30 is attached to the suspension bolt 20 by the bolt fixing portion 33 having the above-described configuration as follows. That is, first, at least a portion of the side of the first bolt fixing portion 33a and the second bolt fixing portion 33b that contacts the suspension bolt is provided with a thread shape Bh that matches the thread of the suspension bolt 20. Alternatively, the thread shape Bh may be provided on a portion of each of the first bolt fixing portion 33a and the second bolt fixing portion 33b, or it may be provided on the entire circumference. With this thread shape Bh engaged with the thread of the suspension bolt 20, the suspension bolt 20 is sandwiched between the first bolt fixing portion 33a and the second bolt fixing portion 33b. In this way, the suspension bolt 20 is fixed by the bolt fixing portions 33.

[0038] As described above, in this embodiment, it is preferable that the first bolt fixing portion 33a and the second bolt fixing portion 33b are integrated by fitting them together using the male fitting portion 33cm and the female fitting portion 33cf. Alternatively, instead of using the above-mentioned fitting, the first bolt fixing portion 33a and the second bolt fixing portion 33b may be integrated together by, for example, bolt fastening. Alternatively, as long as the first bolt fixing portion 33a or the second bolt fixing portion 33b can ensure engagement with the threads of the suspension bolt 20 as described above, either the first bolt fixing portion 33a or the second bolt fixing portion 33b may be flat, as shown in Figure 7.

[0039] Furthermore, the fixing of the suspension bolts 20 and the reinforcing members 30 near the folded-plate roof of a building is what is known as high-altitude work. Here, in order to prevent each part from falling during the work, it is preferable to have the following configuration. That is, for example, as shown in Fig. 8, it is preferable that the first bolt fixing portion 33a or the second bolt fixing portion 33b has an arc shape of more than 180° in plan view. This prevents the first bolt fixing portion 33a or the second bolt fixing portion 33b having the arc shape from falling when attached alone to the suspension bolt 20. In other words, it is preferable that either the first bolt fixing portion 33a or the second bolt fixing portion 33b can be temporarily held on the suspension bolt 20 when fixing the suspension bolt 20 to the reinforcing member 30 during work at height. 9, protrusions 33p may be provided on both arc-shaped ends of the first bolt fixing portion 33a or the second bolt fixing portion 33b, thereby allowing either the first bolt fixing portion 33a or the second bolt fixing portion 33b to be temporarily held in place, similar to the configuration described above.

[0040] As described above, according to the reinforcing material 30 of this embodiment, the bolt fixing portion 33 has a thread shape Bh that matches the thread of the suspension bolt 20 on at least a portion of the side that contacts the suspension bolt 20. As a result, when the bolt fixing portion 33 is separated, the thread shape Bh of the bolt fixing portion 33 is engaged with the thread of the suspension bolt 20, and then the bolt fixing portion 33 is integrated. In this state, the contact portion 32 is brought into contact with the back surface of the folded-plate roof R, and the main body portion 31 is held to the folded-plate roof R.

[0041] In this state, when the suspension bolt 20 tries to bend due to an input such as wind, the input is transmitted from the suspension bolt 20 to the bolt fixing portion 33 and then transmitted to the folded-plate roof R via the contact portion 32. In other words, the input to the suspension bolt 20 is received by the folded-plate roof R. Therefore, the suspension bolt 20 can be reinforced by the reinforcing member 30.

[0042] Furthermore, the threads of the suspension bolt 20 mesh with the thread shape Bh of the bolt fixing portion 33. This prevents the suspension bolt 20 and the bolt fixing portion 33 of the reinforcing member 30 from shifting in the axial direction of the suspension bolt 20 due to the force applied to the suspension bolt 20. Therefore, the force applied to the suspension bolt 20 is reliably transmitted to the folded-plate roof R, thereby reliably reinforcing the suspension bolt 20.

[0043] Furthermore, the reinforcing material 30 and the suspension bolt 20 are fixed together by the bolt fixing portion 33 so that the suspension bolt 20 is sandwiched between them. Therefore, the reinforcing material 30 can be easily and reliably fixed to the suspension bolt 20 without any fastening work. Furthermore, since no fastening member is used, there is no risk of the fastening becoming loose due to vibration or the like, and stable fixation can be achieved. Therefore, the suspension bolt 20 can be reliably reinforced with a small number of work steps.

[0044] Furthermore, the bolt fixing portion 33 is integrated by fitting, which means that the bolt fixing portion 33 can be easily integrated. This makes it easier to fix the reinforcing member 30 to the suspension bolt 20.

[0045] In addition, the contact portion 32 is provided with an attachment portion for attaching an extension member 34 that fills the gap between the contact portion 32 and the back surface of the folded-plate roof R. In other words, the height position of the reinforcing material 30 can be adjusted by providing the extension member 34 between the back surface of the folded-plate roof R and the contact portion 32. In other words, a wide range of dimensions can be accommodated without having to use multiple different types of reinforcing material 30.

[0046] Furthermore, one of the divided bolt fixing portions 33 has an arc shape exceeding 180°. This allows the bolt fixing portion 33 with an arc shape exceeding 180° to be attached to the suspension bolt 20 alone. This makes it easy to temporarily fasten the divided bolt fixing portions 33 before integrating them. This prevents components from falling off, allowing for more stable work.

[0047] Furthermore, protrusions 33p are provided at both arc-shaped ends of one of the divided bolt fixing portions 33. As a result, when one of the bolt fixing portions 33 is attached to the suspension bolt 20, the protrusions 33p engage with the suspension bolt 20. This allows for more stable temporary fastening.

[0048] Here, the folded-plate roof R to which the suspension bolts 20 are attached may have a slope. In other words, the surface to which the suspension bolts 20 are attached may not be parallel to the axial direction of the suspension bolts 20. In such cases, the suspension bolts 20 may be intentionally bent before attachment. In contrast, the outer surface of the contact portion 32 is arc-shaped. As a result, even if the back surface of the folded-plate roof R has a slope as described above, the contact portion 32 can be brought into contact with the folded-plate roof R without changing the angle of the entire reinforcement material 30. Therefore, it is possible to flexibly respond to the slope of the back surface of the folded-plate roof R.

[0049] Furthermore, the gutter fixing structure 100 can reliably reinforce the suspension bolts 20 with fewer work steps.

[0050] 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, the bolt fixing portion 33 is not limited to being divided into two parts as described above, but may be divided into three or more parts. Furthermore, the first bolt fixing portion 33a and the second bolt fixing portion 33b may be molded integrally while being movable. Specifically, in the circumferential direction based on the suspension bolt 20, the ends of the first bolt fixing portion 33a and the second bolt fixing portion 33b on the corresponding sides may be molded integrally, and only the ends on the opposite sides may be provided with the male fitting portion 33cm and the female fitting portion 33cf.

[0051] 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 modified examples may be combined as appropriate. [Explanation of symbols]
