Description

[Technical Field]

[0001] The present invention relates to a gutter cover fastener that connects the covers of drop-cover type gutters installed as road drainage gutters and fixes them to the gutters, and to a method of installing gutter covers using the same. [Background technology]

[0002] Traditionally, drop-lid type gutters have been commonly used as road drainage ditches, but pedestrians walking along the road have complained that the handle holes make it difficult to walk on, and nearby residents have complained that the lids are noisy and rattle.As a countermeasure to these issues, for example, Patent Document 1 describes a method of preventing rattle of the gutter lid by attaching a connector to the gutter lid, which has a pair of fitting parts that fit on the short sides of the gutter lid from the sides and are configured so that they are symmetrical on the back via a gap-forming member. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2008-38583 Summary of the Invention [Problem to be solved by the invention]

[0004] The connector described in Patent Document 1 fits onto the short side of the gutter cover to prevent the gutter cover from rattling, so the connector must be precisely made to fit the gutter cover, and the gutter cover must be new. Therefore, even if the old gutter cover is in a reusable condition, using the connector to resolve the claim would mean replacing the old gutter cover with a new one.

[0005] Therefore, the present invention aims to provide a gutter cover fixing device that can reuse old gutter covers and prevent rattles, etc., and a gutter cover installation method using the same. [Means for solving the problem]

[0006] The gutter cover fixing device of the present invention comprises two cylindrical sections which serve as connecting sections between the covers of drop-down gutter types and into which anchor members are inserted, each of which is erected on both cover receiving sections of the gutter body; a connecting plate section which is provided between the two cylindrical sections and connects the two cylindrical sections; and a bottom plate section which is provided on the connecting plate section and which holds the filler material to be filled into the connecting section.

[0007] The method for installing a gutter cover using the gutter cover fixing device of the present invention is characterized by including: arranging the gutter cover fixing part so as to bridge the connecting parts between the covers of drop-cover type gutters and the two cover receiving parts of the gutter main body; placing the covers on the cover receiving parts of the gutter main body so as to sandwich the gutter cover fixing device; inserting anchor members into each of the two cylindrical parts of the gutter cover fixing device and erecting them on both cover receiving parts of the gutter main body; and filling the gaps on both cover receiving parts and the bottom plate part, including the inside and outside of the two cylindrical parts, with filler material.

[0008] According to the gutter cover fixing device of the present invention, anchor members which serve as connecting parts between the covers of drop-cover type gutter, and which are erected on both cover receiving parts of the gutter body, are inserted into the two cylindrical parts, and the filler material filled in the connecting parts is held on both cover receiving parts and the bottom plate part, including the inside and outside of the two cylindrical parts, so that the covers are fixed to both cover receiving parts of the gutter body in a connected state.

[0009] The gutter cover fastener of the present invention preferably has an uneven surface on the side of the connecting plate portion, which increases the adhesive strength between the side of the connecting plate portion and the filler, thereby connecting the covers more firmly together.

[0010] The gutter cover fastener of the present invention preferably has a separator that limits the range of the filler to be filled in. This limits the range of the filler to be filled in the connecting part, and forms a drain hole in the area where the filler is not filled. [Effects of the Invention]

[0011] (1) By using the gutter cover fixing device of the present invention, it is possible to reuse even old gutter covers and fix the covers to the gutter body in a connected state, thereby preventing rattling, etc.

[0012] (2) By providing the unevenness on the side of the connecting plate portion, the adhesive strength between the side of the connecting plate portion and the filler is increased, and the lids are more firmly connected to each other, further preventing rattling and the like.

[0013] (3) By having a separator that limits the filling area of ​​the filler, a gutter cover with drainage holes can be constructed. [Brief explanation of the drawings]

[0015] FIG. 1 is an oblique view of a gutter cover fixing device in an embodiment of the present invention, FIG. 2 is a plan view of the gutter cover fixing device of FIG. 1, FIG. 3 is a plan view showing the gutter cover fixing device and gutter cover of FIG. 1 placed on the gutter body, FIG. 4 is a cross-sectional view taken along line IV-IV of FIG. 3, FIG. 5 is a plan view of the completed gutter cover using the gutter cover fixing device of FIG. 1, and FIG. 6 is a cross-sectional view taken along line VI-VI of FIG. 5.

[0016] As shown in Figures 1 to 4, a gutter cover fastener 1 in an embodiment of the present invention is used to connect covers 3 of drop-lid type gutters 2 installed as drainage ditches on a road and fix them on a gutter body 20. Anchor members 4 are erected at the connecting parts 30 between the covers 3 of the drop-lid type gutters 2. The anchor members 4 may be reinforcing bars such as anchor bars (inserted bars). The anchor members 4 are erected on both cover receiving parts 21 of the gutter body 20.

[0017] The gutter cover fastener 1 has two cylindrical portions 10 into which the anchor members 4 are respectively inserted, a connecting plate portion 11 provided between the two cylindrical portions 10 and connecting the two cylindrical portions 10, and a bottom plate portion 12 provided on the connecting plate portion 11. In addition, a separator 13 is provided on the side surface of the connecting plate portion 11.

[0018] The tubular portion 10 is a cylindrical pipe into which the anchor member 4 can be inserted. For example, a carbon steel pipe for piping (SGP) can be used as the cylindrical pipe. The tubular portion 10 is welded to both longitudinal ends of the connecting plate portion 11. It is desirable that the top ends of the connecting plate portion 11 and the anchor member 4 are positioned slightly below the finished surface of the filler material 5 (described later) so as not to protrude above the finished surface.

[0019] After the gutter cover fastener 1 is placed so as to bridge both cover receiving portions 21 of the gutter main body 20, the anchor member 4 is installed upright in holes drilled in both cover receiving portions 21 through the tubular portion 10. At this time, it is desirable that the upper end of the anchor member 4 protrudes upward from the tubular portion 10 so that it can be held and inserted into the tubular portion 10. For this reason, the top end of the tubular portion 10 is positioned slightly (for example, about 10 mm) below the top end of the connecting plate portion 11.

[0020] The connecting plate portion 11 and the bottom plate portion 12 are each made of a strip-shaped plate material. For example, a steel plate can be used as the strip-shaped plate material. Concave and convex portions 14 are formed on the side of the connecting plate portion 11. The convex and concave portions 14 are formed in a convex shape by welding buildup, welding other members, or other methods. The bottom plate portion 12 is welded to the bottom of the connecting plate portion 11 so as to form an inverted T shape. The top surface of the bottom plate portion 12 is positioned at the bottom surface of the lid 3. Furthermore, the bottom plate portion 12 is made wider than the handle hole 33 so that it abuts against the underside 32 of the lid 3 and closes the handle hole 33, as will be described later.

[0021] The separators 13 are square tubes with a square or rectangular cross section. Square steel can be used as the square tubes, for example. Four separators 13 are provided on each side of the connecting plate portion 11. The lids 3 are arranged in the connecting portion 30 so as to abut against these separators 13. In other words, the spacing W between the lids 3 in the connecting portion 30 is the distance between the outer surfaces of the separators 13 on both sides of the connecting plate portion 11.

[0022] The construction of a gutter cover using the gutter cover fixing device 1 having the above-described configuration is carried out in the following procedure.

[0023] (1) The gutter cover fixing device 1 is placed on the connecting portion 30. At this time, the gutter cover fixing device 1 is placed so as to bridge the gutter body 20 in the transverse direction.

[0024] (2) The lids 3 are placed on the lid receiving portions 21 of the gutter body 20 so as to sandwich the gutter lid fastener 1. At this time, the lids 3 on both sides of the gutter lid fastener 1 are placed so as to abut against the separators 13. This ensures a gap W between the lids 3. Note that the lids 3 are old gutter lids that are in a reusable state. Conditions for a reusable lid 3 include, for example, ensuring strength, being free of chips, and having the same shape. Note that slight differences in shape are not a problem as long as they are consistent to a certain extent.

[0025] (3) The anchor members 4 are erected at the connecting portions 30 between the covers 3 of the drop-cover type gutters 2. At this time, holes slightly larger than the anchor members 4 are drilled through the cylindrical portion 10 of the gutter cover fastener 1 in each of the cover receiving portions 21 of the gutter body 20. The anchor members 4 are then inserted into the cylindrical portion 10, and the anchor members 4 are erected in both cover receiving portions 21.

[0026] (4) Filler material 5 is filled into the gaps on both lid receiving portions 21, including the inside and outside of the two cylindrical portions 10, and on the bottom plate portion 12. The finished surface of the filler material 5 is flush with the upper surface of the lid 3. It is preferable to use, for example, non-shrinkage mortar, which can be released on the same day, as the filler material 5. At this time, the tops of both lid receiving portions 21, including the inside and outside of the two cylindrical portions 10, are separated by the end surface 31 of the lid 3 and the separator 13, so that the filler material 5 does not leak into the gutter body 20. The bottom plate portion 12 is welded to the bottom of the connecting plate portion 11 in an inverted T-shape, so it does not sag under its own weight, and is sized to abut against the underside 32 of the lid 3 and block the handle hole 33. Therefore, the filler material 5 filled into the gaps on the bottom plate portion 12 does not leak into the gutter body 20. The gap surrounded by the end face 31 of the lid 3, the connecting plate portion 11, and the two separators 13 is not filled with the filler 5, but serves as a drain hole 6 (see FIG. 5) for drainage.

[0027] As a result, the gutter cover fastener 1 is fixed to the gutter body 20 by the mutual adhesive forces of the anchor member 4, tubular portion 10, and filler 5, and the lid 3 is fixed by the adhesive force of the filler 5 filled in the gap between the end face 31 of the lid 3 and the gutter cover fastener 1. In addition, the concave and convex portions 14 formed on the side of the connecting plate portion 11 of the gutter cover fastener 1 function as an anti-slip surface. It is preferable to also form a concave portion on the end face 31 of the lid 3 using a drill or the like to serve as an anti-slip surface.

[0028] As described above, according to the gutter cover fastener 1 of this embodiment, the anchor members 4 that are provided upright on both cover receiving portions 21 of the gutter main body 20 at the connecting portions 30 between the covers 3 of the drop-cover type gutters 2 are inserted into the two cylindrical portions 10, and the filler 5 filled in the connecting portions 30 is held on both cover receiving portions 21 and the bottom plate portion 12, including the inside and outside of the two cylindrical portions 10, thereby fixing the covers 3 to both cover receiving portions 21 of the gutter main body 20 in a connected state. In this way, by using the gutter cover fastener 1, it is possible to reuse old gutter covers as they are and connect and fasten the covers 3 to the gutter main body 20, which is an excellent environmental measure, prevents rattling, and reduces noise generation.

[0029] Furthermore, the gutter cover fastener 1 in this embodiment has unevenness 14 on the side of the connecting plate portion 11 that functions as an anti-slip surface, which increases the adhesive strength between the side of the connecting plate portion 11 and the filler material 5, and more firmly connects the covers 3 together. Furthermore, the handle holes 33 are filled with the filler material 5, which eliminates the difficulty of walking.

[0030] Furthermore, the gutter cover fastener 1 in this embodiment has a separator 13 that limits the filling range of the filler 5, so the filling range of the filler 5 filled in the connecting portion 30 is limited, and drainage holes 6 are formed in the range not filled with the filler 5. These drainage holes 6 function as drainage outlets, and water pools do not form.

[0031] Next, another embodiment of the gutter cover fastener of the present invention will be described. Fig. 7 is a perspective view showing another embodiment of the gutter cover fastener of the present invention. In Fig. 7, components common to the gutter cover fastener 1 described above are given the same reference numerals, and detailed description thereof will be omitted.

[0032] The gutter cover fastener 7 shown in Fig. 7 is used when the drainage hole 6 is not required, and does not include the separator 13 of Fig. 1. The bottom plate portion 15 is composed of a first bottom plate 15A welded to the bottom of the connecting plate portion 11, and two second bottom plates 15B joined and welded to both sides of the first bottom plate 15A in the width direction. The first bottom plate 15A is a strip-shaped plate material that is slightly (for example, about 6 mm) wider than the distance W between the covers 3 of the connecting portion 30. The second bottom plate 15B is a strip-shaped plate material that makes the bottom plate portion 15 wider than the handle hole 33 so as to cover the handle hole 33.

[0033] In addition, the gutter lid fixing device 7 is provided with angle bars 16 on both sides of the connecting plate portion 11 as separators in place of the separators 13 that separate both lid receiving portions 21 together with the end faces 31 of the lid 3. The distance between the outer surfaces of the angle bars 16 on both sides of the connecting plate portion 11 is the spacing W provided in the connecting portion 30.

[0034] With the gutter lid fastener 7 configured as described above, when the lids 3 are placed on the lid receiving portions 21 of the gutter main body 20 so as to sandwich the gutter lid fastener 7, the lids 3 on both sides of the gutter lid fastener 7 are positioned so that they abut against the angle irons 16, ensuring a gap W between the lids 3. Furthermore, when the filler 5 is filled, the tops of both lid receiving portions 21, including the inside and outside of the two tubular portions 10, are partitioned by the end faces 31 of the lids 3 and the angle irons 16, so the filler 5 does not leak into the gutter main body 20. The bottom plate portion 15 is welded to the bottom of the connecting plate portion 11 in an inverted T-shape and therefore does not sag under its own weight, and the bottom plate portion 15 is sized to abut against the underside of the lid 3 and close the handle hole 33, so the filler 5 filled in the gap above the bottom plate portion 15 does not leak into the gutter main body 20.

[0035] Figure 8 is a perspective view showing still another embodiment of the gutter cover fastener of the present invention. In Figure 8, the same components as those in the gutter cover fastener 1 described above are given the same reference numerals, and detailed description thereof will be omitted.

[0036] In the gutter cover fastener 8 shown in Figure 8, the bottom plate portion 41 is provided not in the portion of the handle hole 33 that is formed when the covers 3 are connected to each other, but in the portion of the gap of the interval W that is formed between the covers 3 that is outside the separator 40. In addition, the portion of the handle hole 33 has a mesh portion 42 that is formed in a mesh shape to match the shape of the handle hole 33.

[0037] In the gutter cover fastener 8 configured as described above, the filler 5 is not filled in the area of ​​the handle holes 33 (mesh portion 42), but is filled on the bottom plate portion 41 in the area outside the separator 40. Because the volume of the area above the bottom plate portion 41 outside the separator 40 is smaller than the area of ​​the handle holes 33, less filler 5 is required compared to the case of the gutter cover fastener 1. Furthermore, because the mesh portion 42 exists in the area of ​​the handle holes 33, pedestrian safety and drainage are ensured.

[0038] Figure 9 is a perspective view showing still another embodiment of the gutter cover fastener of the present invention. In Figure 9, the same components as those in the above-described gutter cover fastener 8 are given the same reference numerals, and detailed description thereof will be omitted.

[0039] In the gutter cover fastener 9 shown in Fig. 9, instead of the mesh-like portion 42 of the gutter cover fastener 8 described above, a hole cover portion 43 is formed from a plurality of small pieces 43A made of steel plate or the like. The small pieces 43A are provided at the upper end of the connecting plate portion 11 with a predetermined gap provided so as to fit the shape of the handle hole 33.

[0040] In the gutter cover fastener 9 configured as described above, the filler 5 is not filled in the area of ​​the handle hole 33 (hole cover portion 43), but is filled on the bottom plate portion 41 in the area outside the separator 40. Because the area above the bottom plate portion 41 outside the separator 40 has a smaller volume than the area of ​​the handle hole 33, less filler 5 is required compared to the case of the gutter cover fastener 1. Furthermore, because the hole cover portion 43 exists in the area of ​​the handle hole 33, pedestrian safety and drainage are ensured.

[0041] In the above embodiment, the gutter cover fastener 1 is placed in both cover receiving portions 21 of the gutter body 20, and then the anchor members 4 are erected in both cover receiving portions 21 through the tubular portions 10, but the procedure can also be reversed. That is, the anchor members 4 can be erected in both cover receiving portions 21 in advance, and the gutter cover fastener 1 can be placed so that these anchor members 4 are inserted into the two tubular portions 10. Also, anchor bolts can be used instead of reinforcing bars for the anchor members 4.

[0042] Furthermore, the tubular portion 10 can be a square tube instead of a cylindrical tube. In this case, the square tube can also function as part of the separator 13. The shape and width of the drain hole 6 can also be changed by changing the shape and position of the separator 13 depending on various conditions. Furthermore, the materials for the gutter cover fasteners 1, 7, 8, and 9 can also be reinforced plastics or other metals other than steel. [Industrial Applicability]

[0043] The present invention is useful as a gutter cover fixing device that connects the covers of drop-cover type gutters installed as road drainage ditches, and as a method for installing gutter covers using the same, and is particularly suitable as a gutter cover fixing device that can reuse old gutter covers to prevent rattling, etc., and as a method for installing gutter covers using the same.
