Description

  The present invention provides a vertical grating support that supports a vertical grating that is provided on a water channel such as a drainage groove and that has a plurality of main bars arranged in parallel at a predetermined interval along the longitudinal direction of the water channel. Relates to the device.

  As a groove lid installed on the water flow channel, a plurality of main bars along the groove width direction of the water flow channel are juxtaposed at a predetermined interval, and an appropriate number of cross bars are passed orthogonally to the main bar. A grating having the following structure (hereinafter, horizontal grating) is well known (see, for example, Patent Document 1).

  The above-mentioned horizontal grating is generally formed so that the width in the main bar direction is substantially equal to the groove width of the water passage groove, and covers the entire groove width of the water passage groove. A predetermined number is continuously arranged along the longitudinal direction of the path. In the case of installing the horizontal grating, a grating receiving frame is attached on the water channel, and the horizontal grating is supported by the grating receiving frame. For example, as shown in FIG. 12, in the grating receiving frames a and a, the horizontal edge c mounted on the left and right side walls e and e constituting the water flow channel d, and the horizontal edge c It is formed in an L-shaped cross section by a vertical partitioning portion b rising from the outer end. The grating receiving frames a and a are mounted on the left and right side walls e and e of the water flow channel d and are attached to the water flow channel d. After being installed in this way, the horizontal grating f is installed by being mounted on the horizontal edges c and c of the grating receiving frames a and a. Here, since the both ends of each main bar g are supported on the horizontal edge portions c and c, the load applied to the horizontal grating f from above is applied to each horizontal bar f. It comes to support. Thereby, even when a heavy object such as an automobile passes, it can withstand the relatively large load.

By the way, when the water channel is provided so that humans or automobiles cross over it (for example, a side channel), the horizontal grating installed on the water channel along this transverse direction. There will be a main bar. When a stroller or wheelchair crosses over this horizontal grating, there is a concern that these wheels may fall between the main bars. For this reason, there is a configuration in which the interval between the main bars is narrowed in the horizontal grating.
Japanese Patent Laying-Open No. 2003-33879 (FIG. 2)

  In addition to the above-mentioned horizontal grating, there is also a vertical grating in which main bars along the longitudinal direction of the water flow channel are arranged in parallel at a predetermined interval. This vertical grating is excellent in the effect of preventing the wheel of a wheelchair or the like from falling because the crossing direction and the main bar are almost perpendicular to each other when a baby stroller, a wheelchair or the like crosses the vertical grating.

  Here, as the vertical grating, a configuration in which side bars that respectively support both ends of each main bar are provided in the groove width direction is common. When this vertical grating is installed so as to cover the entire groove width of the water channel, if it is installed on the water channel using the above-mentioned grating receiving frame for installing the horizontal grating, the vertical grating is The both ends of the side bar are supported by the grating receiving frame. For this reason, the vertical gratings mainly support the load applied to the vertical gratings by the side bars on both sides, and withstand the load when a heavy object such as an automobile passes through this. There was a problem that the strength could not be demonstrated. For this reason, installing the vertical grating is limited to a place where a large load from an automobile or the like is not applied.

  The present invention proposes a support device for longitudinal grating that can exhibit the strength that the longitudinal grating can withstand a large load of an automobile or the like when the longitudinal grating covering the entire groove width of the water channel is installed. Is.

  The present invention supports a vertical grating made of a plurality of main bars along a longitudinal direction in parallel at a predetermined interval on a water channel, and the water channel at the upper part of the opening of the water channel. A plurality of multipliers fixed in a transverse manner at predetermined intervals along the longitudinal direction of the water flow channel at a lower position at a height interval substantially corresponding to the thickness of the grating than the reference plane at the periphery. A support device for longitudinal grating that includes a mounting beam and supports vertical grating by the mounting beam. Here, as the reference plane, a surrounding road surface or ground where the vertical grating is installed is shown.

  In such a configuration, since a plurality of mounting beams are passed and fixed to the upper part of the opening of the water flow channel, when the vertical grating is supported by the mounting beams, this mounting beam is mounted. The main bar of the vertical grating is supported by the beam. Therefore, since the load applied to the vertical grating is supported by a plurality of mounting beams that support a plurality of main bars, the vertical grating is applied to a load applied by a heavy weight such as an automobile. On the other hand, sufficient strength can be exhibited.

  Here, the structure of this invention is used suitably as what supports the vertical grating installed so that the whole groove width of a water flow channel may be coat | covered. That is, when the wide vertical grating is supported, the above-described effects of the present invention can be conspicuous. In this case, the vertical grating is supported in an area of the riding beam exposed from the upper opening of the water channel.

  In addition, the mounting beam is fixed at a position that is lower than the reference plane on which the vertical grating is disposed by a height interval substantially corresponding to the thickness of the vertical grating. When the eye grating is supported, the upper surface of the vertical grating is substantially equal to the reference plane. Therefore, an automobile or a person can easily pass on the vertical grating, and the mounting beam can stably support the load applied to the vertical grating.

  In addition, in the mounting beam disposed along the longitudinal direction of the water channel, the number of the beams is appropriately set according to the groove width of the water channel and the load acting on the vertical grating. can do. In order to properly support the load acting on the vertical grating, it is possible to suitably use the interval between the mounting beams to be shorter than the length of the main bar. Moreover, even if it exists in the cross-sectional shape of a mounting beam, it can set suitably according to required rigidity.

  In addition, as described above, by installing the vertical grating on the water channel, it is possible to prevent the wheels from falling between the main bars when a stroller, a wheelchair or the like crosses over it. Arise.

  The above-described vertical grating support device, comprising a pair of left and right support frames provided on both sides of the water channel, and having a vertical partition section that divides the water channel on both sides, A configuration is proposed in which both vertical frame portions are fixed to the left and right support frames so that both ends of the mounting beam are fixed to each other and the support frames are connected to each other so as to fix the left and right sides of the groove.

  Here, in the vertical partitioning portion of the support frame, partitioning the water channel on both sides indicates, for example, partitioning the water channel and the paving material laid outside thereof. That is, the upper opening of the water channel is mainly defined. Furthermore, this vertical partition part also has the effect | action which controls the movement of the width direction of this vertical grating in the case of installing vertical grating. Moreover, in this vertical division part, it can be set as the structure provided perpendicularly | vertically to the upper side from the fixed position of the riding beam, or the structure provided perpendicularly to the upper and lower sides of the riding beam. In addition, as a latter structure, a vertical division part can also comprise the side wall inner surface of a water flow groove part partially or entirely.

  By the way, when attaching the grating receiving frame of the conventional configuration in which the above-described horizontal grating is installed to the water channel, the pair of left and right support frames are temporarily fixed at predetermined intervals by a predetermined width determining member in advance. Attached on the waterway. And it is common to remove this width determining member before installing the horizontal grating. On the other hand, in the configuration of the present invention, since the mounting beam is formed integrally by connecting a pair of left and right support frames, this mounting beam also has a role as a width determining member. Yes. Therefore, the work of removing the width determining member as in the conventional configuration is not required, and the workability of the attaching work is improved.

  In addition, in the vertical grating supporting device of the present invention, the vertical grating is correctly fixed to the water channel so that the vertical grating can be arranged in a line along the longitudinal direction of the water channel. It is required to be done. For this reason, it is preferable that a fixing means for positioning the vertical grating supporting device at a correct position is provided at the time of construction. As this fixing means, what is equipped with the press contact fixing means for pressing to the side wall inner surface or outer surface of a water flow channel and fixing to a water flow channel can be used suitably.

  As the above-mentioned pressure contact fixing means, for example, a configuration in which the mounting beam is disposed in an inward portion located between the side walls of the water flow channel, and is fixed to both side walls by being pressed against the inner surfaces of the left and right side walls. Is proposed. In such a configuration, the vertical grating support device can be positioned and fixed by being pressed against the inner surfaces of the left and right side walls. Here, if the water passage groove is formed by continuously connecting groove members having side walls on the left and right in the longitudinal direction, the pressure contact fixing means of this configuration is in pressure contact with the inner surfaces of the left and right side walls, By holding the groove member in a state of being pressed outward from the inside, the vertical grating supporting device is fixed to the groove member. As this pressure contact fixing means, a structure comprising a screw member such as a bolt shape, which is fixed by screwing the screw member and tightening the tip end portion of the screw member to the inner surface of the side wall can be suitably used. Thereby, since a support frame and a mounting beam are fixed to a side wall, the installation operation | work of pavement materials, such as concrete and a decorative tile, can be performed to the outer side of the vertical division part of a support frame. Furthermore, since the horizontal position of the support frame and the mounting beam can be adjusted, it is easy to determine the horizontal position with respect to the water channel, and it can be attached in almost one row along the longitudinal direction. As well as improving the work accuracy. In addition, since this pressure contact fixing means can be positioned and fixed on the inner surface of the side wall, in the case of constructing a water channel, the groove member described above is installed, and the pavement material is installed near both sides of the groove member. After the installation work, the vertical grating support device can be attached. Therefore, in the process of constructing the water channel, there is an advantage that the construction work can be made more efficient because the work time for attaching the vertical grating support device can be set relatively freely.

  Alternatively, in the above-described vertical grating support device, the both side walls are arranged by pressing the left and right support frames or the left and right end portions of the mounting beam and pressing the left and right side walls constituting the water flow channel. There is proposed a configuration provided with a press-fixing means to be consolidated to the head. In such a configuration, the longitudinal grating supporting device is provided with pressure contact fixing means for positioning and fixing with respect to the water flow channel. Here, assuming that the water flow groove is formed by continuously connecting groove members having side walls on the left and right in the longitudinal direction, the press contact fixing means of this configuration is in pressure contact with the outer surfaces of the left and right side walls, By holding the groove member in a state in which the groove member is clamped from both sides, the vertical grating supporting device is fixed to the groove member. As the pressure contact fixing means, a structure in which a bolt-like screw member or the like is screwed to fasten the tip end portion of the screw member to the outer surface of the side wall to be fixed to the side wall can be suitably used. Thereby, since a support frame and a mounting beam are fixed to a side wall, the installation operation | work of the pavement material to the outer side of the vertical division part of a support frame can be performed easily. Furthermore, since the horizontal position of the support frame and the mounting beam can be adjusted, it is easy to determine the horizontal position with respect to the water channel, and it can be attached in almost one row along the longitudinal direction. As well as improving the work accuracy.

  In the vertical grating support device described above, the support frame is coupled to the vertical partition portion and the upper surface of the side wall that forms the water channel by being coupled inward from the vertical partition portion. And the mounting beams are mounted on the horizontal edges of the left and right support frames and passed to the support frames, and both the support frames are connected to the horizontal grooves. A configuration is proposed in which the upper and lower sidewalls are connected so as to be spaced apart from each other.

  In this configuration, the mounting beam is mounted on the side wall that forms the water channel through the horizontal edge portion. Since the mounting beam is mounted on the horizontal edge and fixed, and the plurality of mounting beams and the support frame pair are integrated, each horizontal edge and the mounting beam are positioned relative to each other. ing. That is, the surface direction of the support surface of each mounting beam that supports the vertical grating can be accurately set in advance for each horizontal edge. For example, in a configuration in which the horizontal edge and the support surface of the mounting beam are integrally formed so as to be parallel to each other, the horizontal edge is mounted on the side wall so that the support surface of the mounting beam is It becomes almost horizontal. Therefore, the horizontal level adjustment work for making the support surface of the mounting beam a desired horizontal direction is also facilitated.

  The mounting beam can be suitably used either in a configuration in which it is in contact with and joined to the upper surface of the horizontal edge of the support frame, or in a configuration in which it is in contact with the upper surface of the horizontal edge and joined with the vertical partitioning portion. . In this way, the mounting beam is in contact with and joined to the upper surface of the horizontal edge, so that the surface direction of the support surface of the mounting beam can be accurately set, and the mounting beam and the left and right support frames Are firmly consolidated to prevent mutual displacement. In addition, the mounting beam can be suitably used either in a configuration that is disposed on the inner side of the vertical partition portion or in a configuration that penetrates the vertical partition portion.

  Further, in the above-described vertical grating support device, the support frame is coupled to the vertical partition portion in which a through-hole penetrating the mounting beam inward and outward is formed and outward from the vertical partition portion, A horizontal edge mounted on the upper surface of the side wall constituting the water flow channel, and the mounting beam passes through the through hole of each vertical partitioning portion of the left and right support frames to each horizontal edge. A configuration is proposed in which the frames are mounted and passed to the support frame, and both the support frames are connected such that each horizontal edge portion can be mounted on the upper surface of the left and right side walls of the water flow channel. Is done.

  In such a configuration, since the vertical partition is inward from the horizontal edge mounted on the side wall of the water flow channel, the opening width of the upper opening of the channel groove defined by the vertical partition is set. It can be set narrowly. Therefore, a comparatively short width dimension can be applied to the vertical grating installed between the left and right vertical sections. And the vertical grating | lattice grating with a short width dimension can reduce manufacturing cost and purchase cost according to the width dimension. Thus, since it has the outstanding advantage that the cost required for vertical grating can be reduced, it is possible to exhibit an advantage in market competition.

  Even in this configuration, the mounting beam is mounted and fixed on the horizontal edge of the support frame, and the plurality of mounting beams and the support frame pair are integrated. Since the mounting beam is positioned relative to each other, the surface direction of the support surface of each mounting beam that supports the vertical grating can be accurately set in advance for each horizontal edge. For example, if the horizontal edge and the support surface of the mounting beam are integrally formed so as to be parallel to each other, the horizontal edge is mounted on the side wall, thereby supporting the mounting beam. The surface is almost horizontal. In this way, the horizontal level adjustment work for making the support surface of the riding beam the desired horizontal direction is also facilitated.

  The mounting beam can be suitably used either in a configuration in which it is abutted and joined to the upper surface of the horizontal edge portion of the support frame or in a configuration in which it is joined to the vertical partition portion and abutted against the upper surface of the horizontal edge portion. . With such a configuration, the surface direction of the support surface of the mounting beam can be accurately set, and the mounting beam and the left and right support frames are firmly fixed to prevent mutual displacement.

  Furthermore, in the vertical grating support device described above, the mounting beam is passed to the left and right support frames so that the left and right ends of the mounting beam are mounted on the upper surfaces of the side walls constituting the water flow channel. A configuration is proposed.

  In such a configuration, since the mounting beam is directly mounted on the upper surface of the side wall, the surface direction of the support surface that supports the vertical grating of the mounting beam with respect to the upper surface of the side wall becomes clear. Therefore, it is possible to easily perform a horizontal level adjustment operation for placing the mounting beam on the upper surface of the side wall so that the support surface is in the horizontal direction.

  As the riding beam, either a configuration in which both end surfaces thereof are joined to the inner surface of the vertical partition portion of the support frame or a configuration in which both end portions penetrate the vertical partition portion of the support frame can be suitably used. Further, in the latter configuration, the vertical partition portion can be provided on the side wall of the water flow channel, or can be provided on the inner side or the outer side of the side wall. Here, as described above, the vertical section defines the upper opening of the water channel, so that it is provided on the inner side of the side wall or on the inner edge of the side wall as a configuration that penetrates the riding beam. The upper opening width of the water channel can be set relatively narrow. Accordingly, as described above, a product having a short vertical grating width can be applied, and the cost required for the vertical grating can be reduced. Therefore, excellent market competitiveness can be exhibited.

  On the other hand, in the above-described vertical grating supporting device, the vertical partition portion forming the side wall inner surfaces of the both side walls constituting the water flow channel, and the water flow channel are coupled to the lower ends of both vertical partition portions. A groove-shaped support body having a U-shaped cross section having a bottom portion that forms the floor surface of the bottom wall, and the mounting beams are fixed with both ends fixed to the left and right vertical partition portions. A configuration is proposed.

  In such a configuration, by attaching the groove-shaped support, a water flow channel can be formed by the inner region of the groove-shaped support, and the vertical grating is formed by the mounting beam. It can be supported. That is, in this configuration, both the formation of the water flow channel and the support of the vertical grating can be generated simply by being attached. For example, after the vertical grating supporting device of this configuration is continuously arranged, concrete is poured into both sides and hardened to form a water channel, and at a predetermined interval above the opening of the water channel. The vertical grating can be supported on the mounted beam. Therefore, since the groove-shaped support body and the mounting beam can be fixed with high accuracy in advance, by performing the positioning work of the groove-shaped support body, the support surface of the mounting beam is made to be in the horizontal direction. Horizontal level adjustment work can be performed, and workability of construction work is improved.

  Here, both ends of the mounting beam are passed and fixed to the upper positions of the vertical partition portions on both sides. The fixed position is set as a lower position at a height interval substantially corresponding to the thickness of the vertical grating from the upper end of the vertical partition portion, and the upper end of the vertical partition portion and the reference plane are aligned. And this vertical division part divides a water channel from both sides.

  As described above, the present invention traverses at a predetermined interval along the longitudinal direction of the water flow channel at a position lower than the reference plane of the periphery of the water flow channel at a height interval substantially corresponding to the thickness of the grating. Longitudinal grating support that is provided with a plurality of mounting beams that are passed in a fixed manner at predetermined intervals along the longitudinal direction of the water flow channel, and that supports the vertical grating by the mounting beams. Since it is a device, even if a heavy load such as an automobile is applied to the vertical grating, it can withstand the load by supporting each main bar of the vertical grating by a plurality of mounting beams. Sufficient strength can be exhibited. And since the vertical grating can be arrange | positioned, when a stroller, a wheelchair, etc. cross, the wheel can prevent falling to the grating | lattice of grating.

  In addition, it is provided with a pair of left and right support frames that are disposed on both sides of the water flow channel and have vertical partitioning sections that divide the water flow channel on both sides thereof, at intervals that define the left and right sides of the water flow channel. In the configuration in which both ends of the mounting beam are fixed to the left and right support frames so as to fix both vertical partition portions and the both support frames are connected, the left and right support frames and the mounting beam Since these are integrally formed, the workability of the attachment work can be improved.

  The support frame includes a vertical partition portion and a horizontal edge portion that is coupled inwardly from the vertical partition portion and is mounted on the upper surface of the side wall that forms the water flow channel. The beam is mounted on each horizontal edge of the left and right support frames and passed to the support frame, and both support frames can be mounted on the upper surfaces of the left and right side walls of the water flow channel. In the configuration in which the gaps are connected to each other, the horizontal level adjustment work for installing the vertical grating can be easily performed, and the workability can be improved.

  In addition, the support frame is coupled to the vertical partition portion in which a through-hole penetrating the mounting beam inward and outward, and the vertical partition portion outwardly, and rides on the upper surface of the side wall constituting the water flow channel. A horizontal edge to be mounted, and the mounting beam passes through the through holes of the vertical partition portions of the left and right support frames and is mounted on each horizontal edge and passed to the support frame, In the configuration in which both support frames are connected such that each horizontal edge portion can be mounted on the upper surfaces of the left and right side walls of the water flow channel, respectively, the support frame is defined by the vertical partition portion. Since the opening width of the upper opening of the water channel can be set narrow, it is possible to install vertical grating having a short width dimension. Thereby, the cost required for the vertical grating can be reduced, and the overall market competitiveness can be exhibited. Further, the horizontal level adjustment work for installing the vertical grating can be easily performed, and the workability can be improved.

  In addition, in the configuration in which the left and right ends are placed on the pair of left and right support frames so that the left and right ends thereof are mounted on the upper surface of the side wall constituting the water flow channel, The horizontal level adjustment work for installing the eye grating can be easily performed, and workability can be improved.

  Further, a vertical partition part forming the side wall inner surfaces of both side walls constituting the water flow channel, and a bottom part forming a floor surface of the bottom wall coupled to the lower ends of both vertical partition parts. In a configuration comprising a U-shaped groove-shaped support body, and the mounting beam is fixed to the left and right vertical sections, respectively, and passed between the grooves. Since the body and the mounting beam can be fixed with high accuracy, the workability of the construction work can be improved and the precision of the construction work can be improved.

  Embodiments according to the present invention will be described in detail with reference to the accompanying drawings.

  As shown in FIGS. 1 and 2, the water flow channel 1 includes a plurality of groove members 2 composed of U-shaped grooves formed in a substantially U-shaped cross section by the bottom wall 3 and the left and right side walls 4, 4. It is built by embedding in a row at a predetermined depth position on the ground.

  Further, the vertical grating 5 installed on the water flow channel 1 includes a plurality of main bars 6 arranged in parallel at predetermined intervals along the longitudinal direction of the water flow channel 1, and each main bar 6. It is composed of two side bars (not shown) passed to both ends along the longitudinal direction, and a cross bar 7 passed orthogonally to each main bar 6 at a predetermined interval between the side bars. ing. The vertical grating 5 has a width orthogonal to the longitudinal direction substantially equal to the groove width of the water flow groove 1 described above, and can cover the entire width direction of the water flow groove 1. Yes.

  The vertical grating support device 10 according to the first embodiment is provided on the water channel 1 and is used to install the vertical grating 5 so as to cover the upper opening of the water channel 1. is there. The vertical grating support device 10 includes a pair of left and right support frames 11, 11 and a plurality of mounting beams 12 that are passed through the support frame pair and are juxtaposed at predetermined intervals in the longitudinal direction of the support frame 11. Prepare. The pair of left and right support frames 11, 11 have an L-shaped cross section including a vertical partition portion 13 that partitions the water flow channel on both sides thereof, and a horizontal edge portion 14 that is continuous from the vertical partition portion 13. Yes. The left and right support frames 11, 11 have the horizontal edges 14, 14 facing inward, and the horizontal edges 14, 14 are mounted on the left and right side walls 4, 4 of the groove member 2. The plurality of mounting beams 12 are connected in parallel to each other.

  In the support frame 11, a plurality of through holes 15 penetrating the end 12 a of the riding beam 12 are formed in the vertical partition portion 13. The mounting beam 12 is mounted on the horizontal edge portion 14 with the end of the end 12a penetrating from the through-hole 15 and the portion of the end 12a located inside the through-hole 15. It is like that. Here, both end portions 12a and 12a of the mounting beam 12 pass through the through holes 15 of the left and right support frames 11 and 11, and the lower surfaces of the both end portions 12a and 12a are connected to the horizontal edge portions 14 and 14, respectively. The mounting beam 12 and the support frames 11 and 11 are joined to each other by welding in contact with the upper surface. In this way, the pair of left and right support frames 11 and 11 and the plurality of mounting beams 12 are integrated to constitute a vertical grating support device 10.

  When the support frame 11 is attached on the side wall 4 of the groove member 2, the upper surface of the riding beam 12 is below the road surface 9 (the surface of a road surface material 19 described later) at the periphery of the water flow groove 1. The height of the vertical partition portion 13, the thickness of the horizontal edge portion 14, the thickness of the mounting beam 12, etc. are appropriately set so as to be positioned at a height interval substantially corresponding to the thickness of the vertical grating 5. Yes. Thereby, when the vertical grating 5 is installed, the upper surface of the vertical grating 5 and the road surface 9 become substantially uniform. The road surface 9 is a reference plane according to the present invention.

  On the other hand, the number of the mounting beams 12 that connect the pair of left and right support frames 11 and 11 is set so that sufficient strength can be exerted against the load applied on the vertical grating 5. That is, the number of the mounting beams 12 and the distance in the longitudinal direction are set based on the vertical and horizontal dimensions of the vertical grating 5, the number of main bars, the strength and rigidity of the mounting beam 12, etc. so that a desired load capacity can be exhibited. Will be.

  The support frame 11 has a horizontal edge portion 14 formed in a flat plate shape, and the mounting beam 12 has a square pipe shape in which the upper surface and the lower surface are substantially parallel. By mounting the lower surfaces of both end portions 12a, 12a of the mounting beam 12 so as to be in contact with the upper surfaces of the horizontal edge portions 14, 14, the left and right support frames 11, 11 are mounted on the horizontal edge portions 14 respectively. , 14 are held in a state along the same plane direction. Furthermore, even if it exists in the some mounting beam 12 which connects this support frames 11 and 11, each upper surface will be in the state along the same plane direction. Therefore, if the vertical grating support device 10 having this configuration is placed along the horizontal direction, the vertical grating 5 can also be installed along the horizontal direction. Further, for example, when the groove member 2 is disposed with the height positions of the side walls 4 and 4 being shifted, or when the groove member 2 is inclined to one side, the lower one is provided. By interposing an adjustment member having a predetermined thickness on the vertical axis, the vertical grating support device 10 is attached along the horizontal direction relatively easily. In this way, the horizontal level adjustment operation can be easily performed. Further, even when the height positions of the continuously disposed groove members 2 are deviated, the heights of the vertical grating supporting devices 10 can be made relatively easy.

  Furthermore, flat fixing rods 16 and 16 are joined by welding to both ends of the mounting beam 12 that protrude through the through holes 15 and 15 of the left and right support frames 11 and 11. It is suspended downward. Here, the length of the mounting beam 12 is made longer by a predetermined amount than the distance between the outer surfaces 4 b and 4 b of the side walls 4 and 4 of the groove member 2. For this reason, when the vertical grating support device 10 is provided on the water channel 1, the fixing rods 16, 16 are located outside the side walls 4, 4. The interval between the side walls 4 and 4 and the fixing rods 16 and 16 is set to such an extent that the fastening action of the fixing screws 17 and 17 to be described later can be appropriately exhibited.

  A screw hole (not shown) is opened in the lower part of the fixing rod 16, and a fixing screw 17 is screwed into the screw hole from the outside. Here, the fixing screw 17 is a pressure contact portion whose tip is pressed against the outer surface 4 b of the side wall 4. Then, in a state where the vertical grating supporting device 10 is disposed on the water flow channel 1, the fixing screws 17 screwed into the fixing rods 16 on the left and right sides are screwed in the tightening direction, The front ends of the fixing screws 17 and 17 are brought into pressure contact with the outer surfaces 4b and 4b of the side walls 4 and 4, and the vertical grating supporting device 10 is attached via the tightening action.

  In the configuration including the fixing rods 16 and 16 and the fixing screws 17 and 17 as described above, the fixing screws 17 and 17 are tightened from both the left and right sides. Even if the linearity is somewhat poor in a state where the plurality of constituting groove members 2 are arranged, the deviation can be absorbed by adjusting the screwing operation of the left and right fixing screws 17, 17. it can. Therefore, the plurality of vertical grating support devices 10 that are continuous along the water flow channel 1 can be aligned in a straight line, and the construction accuracy can be easily improved.

  The fixing rod 16 and the fixing screw 17 constitute the pressure fixing means of the present invention.

  The support frames 11 and 11 and the mounting beam 12 described above are formed using a metal material such as steel or stainless steel as a material. Here, the support frame 11 may be formed by bending one metal plate to have an L-shaped cross section, or joining two metal plates so as to have an L-shaped cross section by welding. It may be formed. And the support frame 11 is set to the predetermined length over the longitudinal direction of the some groove member 2 made into a line form. On the other hand, as the mounting beam 12, an extruded material or a drawing material can be used.

  The above-described vertical grating support device 10 is attached on the groove member 2 constituting the water flow channel 1. The horizontal edge portions 14 and 14 of the left and right support frames 11 and 11 are placed on the upper surfaces of the side walls 4 and 4 of the groove member 2. Then, by screwing the left and right fixing screws 17, 17 in the tightening direction, the tips (pressure contact portions) of the fixing screws 17, 17 are pressed against the outer surfaces 4 b, 4 b of the side wall 4. At this time, the screwing operation of the left and right fixing screws 17 and 17 is adjusted so that the plurality of vertical grating support devices 10 arranged in a straight line are aligned. In this way, the vertical grating support device 10 is fixed to the groove member 2.

  Here, the plurality of mounting beams 12 passed to the left and right support frames 11, 11 have both end portions of the upper surfaces of the side walls 4, 4 via the horizontal edges 14, 14 of the support frames 11, 11. It is to be held in a state of being mounted on 4a, 4a.

  In this way, when the vertical grating supporting device 10 is attached along the water channel 1, the concrete 18 is embedded around the water channel 1, and the road surface of the decorative tile or the like is formed on the surface layer. The material 19 is installed continuously. That is, a reference plane around the water channel 1 according to the present invention is formed by the surface of the road surface material 19 (hereinafter, the road surface 9). Since this road surface material 19 is installed outside the vertical partition portions 13 and 13 of the support frames 11 and 11, the vertical partition portions 13 and 13 partition the upper opening of the water flow channel 1 from the periphery thereof. The installation work of the road surface material 19 can be easily performed.

  Then, the vertical grating 5 is mounted on the vertical grating supporting device 10 attached as described above. Here, each vertical bar grating 5 is installed on the water flow channel 1 with its main bar 6 supported by the mounting beam 12 of the vertical grating support device 10. That is, in the vertical grating 5, each main bar 6 is supported by a plurality of mounting beams 12, and the mounting beams 12 are placed on the side walls 4, 4 via the horizontal edges 14, 14 of the support frames 11, 11. It is supposed to be on board. Therefore, even when a heavy load such as an automobile is applied to the vertical grating 5, the load is applied to the load by the mounting beam 12 mounted on the side walls 4, 4 through the horizontal edges 14, 14. Can withstand the strength.

  Further, as described above, the vertical grating support device 10 is formed by integrating a pair of left and right support frames 11 and 11 and a plurality of mounting beams 12 in advance. For this reason, this structure does not require the operation | work which removes the width determination member of a right-and-left support frame like the conventional structure mentioned above. Therefore, there is an advantage that the attachment work can be simplified and the work time can be shortened.

  In addition, by installing the vertical grating 5 by the vertical grating supporting device 10, when a thing having a narrow wheel such as a stroller or a wheelchair crosses, the wheel is the main of the vertical grating 5. It can prevent falling between the bars 6. Accordingly, there is an advantage that the interval between the main bars 6 can be freely set as compared with the horizontal grating.

A plurality of mounting beams 22 are handed over to 21 and 21. The mounting beam 22 is mounted on the horizontal edges 24 and 24 of the support frames 21 and 21 between the vertical partition portions 23 and 23 of the support frames 21 and 21 mounted on the side walls 4 and 4 of the groove member 2. Then, they are joined to the horizontal edges 24, 24 by welding. And the space | interval is set so that the horizontal edge parts 24 and 24 may be mounted on the side walls 4 and 4 which comprise the water flow path 1 between the pair of left and right support frames 21 and 21.

  When the left and right support frames 21 and 21 are formed by bending a single metal plate such as steel or stainless steel into an L-shaped cross section, the bent portions are curved. Similarly, even if two metal plates are joined by welding so as to have an L-shaped cross section, a welded portion is formed at the joint site. Therefore, in order to abut the lower surfaces of both end portions 22a and 22a of the mounting beam 22 and the upper surfaces of the horizontal edge portions 24 and 24, the length of the mounting beam 22 is set to be equal to that of the left and right support frames 21 and 21. It is slightly shorter than the distance between the vertical partition portions 23 and 23. This stabilizes the mounting beam 22 on the horizontal edges 24 and 24 of the support frames 21 and 21 so that both ends of the mounting beam 22 do not come into contact with the bent part or the joint part of the support frame 21.

It will be posted. And the same operation effect as Example 1 mentioned above can be exhibited. Further, in the configuration of the second embodiment, it is not necessary to form the through hole 15 in the support frame 11 as in the first embodiment. Therefore, the manufacturing cost can be reduced as compared with the first embodiment.

  On the other hand, in the second embodiment, the mounting beam 22 is configured to be shorter than the distance between the vertical partition portions 23 and 23 of the support frames 21 and 21. As another configuration, as shown in FIG. Further, the mounting beam 27 can be formed as a longitudinal grating supporting device 20 ′ having a length in which both end surfaces thereof are in contact with the inner surfaces of the vertical partition portions 23 and 23, and chamfering the lower portions of both ends. When the mounting beam 27 is passed to the left and right support frames 21, 21, it does not come into contact with the bent portions (or joint portions) of the support frames 21, 21, and does not touch the horizontal edges 24, 24. You can touch. In this configuration, a pair of left and right support frames 21 and 21 can be coupled via the mounting beam 27 at a predetermined interval by contacting the end surface of the mounting beam 27 to the inner surface of the vertical partition 23 of the support frame 21. Therefore, this interval can be generated stably.

  As another example, a square pipe-shaped mounting beam is formed at both ends thereof with a contact step edge cut vertically upward from the lower surface, and from the contact step edge outward along the horizontal direction. It can also be set as the structure provided with the mounted board edge. In this case, the mounting edge of the mounting beam is mounted on the horizontal edge 24 of the support frame 21, and the contact step edge is contacted with the inner end surface of the horizontal edge 24, The mounting beam is passed to the pair of left and right support frames 21 and 21 and joined by welding. In this configuration, the left and right support frames 21 and 21 are mounted at predetermined intervals by bringing the contact step edges of the mounting beams into contact with the inner end surfaces of the horizontal edge portions 24 and 24 of the left and right support frames 21 and 21, respectively. Since it can couple | bond via a mounting beam, this space | interval can be produced | generated stably.

Here, the inner ends of the horizontal edge portions 54, 54 are in contact with the inner end of the riding edge portion 53. That is, the distance between the left and right support frames 51 and 51 is defined by the distance between the mounting edges 53 and 53 on both the left and right sides of the mounting beam 52. As a result, the left and right support frames 51, 51 can stably form the left and right intervals according to the distance between the mounting edges 53, 53. In other words, the mounting beam 52 is passed between the left and right support frames 51, 51.

  Further, the mounting edge portions 53 and 53 of the mounting beam 52 have a depth from the upper surface of the mounting beam 52 equal to the plate thickness of the horizontal edge portion 54 of the support frame 51 described above.

It becomes the distance between the upper ends of 4c and 4c. Here, the vertical partition parts 63 and 63 partition the upper opening of the water flow channel 1 from the peripheral road surface 9. Therefore, in the sixth embodiment, the opening width of the upper opening of the water flow channel 1 is narrower than that of the first embodiment (see FIG. 1). In the case where the vertical grating supporting device 60 is attached, the vertical grating 5 'installed therein is shorter in width than the vertical grating 5 installed in the first embodiment. Things can be applied. The vertical grating 5 'can be obtained by reducing the number of main bars 6 and the length of the cross bar 7'. That is, the vertical grating 5 'can reduce the raw material cost and the molding process as compared with the vertical grating 5 installed in the first embodiment described above. Can be suppressed. Accordingly, by attaching the vertical grating support device 60 of the sixth embodiment, the width of the upper opening of the water flow channel 1 can be narrowed, and the vertical grating 5 'having a short width can be applied. Superiority is improved. Further, unlike the first to fifth embodiments described above, the sixth embodiment has an advantage that dust such as butts are not collected there because there is no horizontal edge or the upper surface 4a of the side wall 4 under the vertical grating 5 '. .

That is, the upper surface of the mounting beam 82 is located below the road surface 9 by the thickness of the vertical grating 5. The vertical grating supporting device 80 is fixed by anchor portions 84 and 84 being embedded in the concrete 18.

  Note that the vertical grating support device 80 of the present embodiment, as described above, is configured such that the two vertical partition portions 83 and 83 constitute both side surfaces of the water flow channel 1 ′. The width of the water flow channel 1 ′ is defined by the mounting beam 82 that defines the interval between the partition portions 83, 83. This means that the length of the riding beam 82 is determined according to the width of the water flow channel 1 ′. For this reason, the left and right support frames 81, 81 and the plurality of mounting beams 82 can be integrally formed in advance before construction, and can be molded with high accuracy. Then, it is possible to form the water passage groove 1 ′ having a predetermined width and to fix the water passage groove 1 ′ only by positioning at the time of construction. Therefore, even in the present embodiment, there is no need to remove the width determining members of the left and right support frames as in the conventional configuration described above, and the attachment work can be simplified and the work time can be shortened.

However, the strength that can withstand the load can be exhibited. Further, similarly to the above-described sixth embodiment, since there is no horizontal edge or upper surface of the side wall under the vertical grating 5, there is an advantage that dust such as a cigarette butt does not accumulate there.

  The configuration of the eighth embodiment is the same as that of the first embodiment except for the configuration described above, and the same components are denoted by the same reference numerals and the description thereof is omitted.

  In the vertical grating support device 90 of Example 9, as shown in FIG. 11, the U-shaped cross-section support 91 and the upper opening of the gutter-type support 91 were passed and fixed. And a plurality of mounting beams 92. Here, the channel-shaped support body 91 is composed of vertical partitioning portions 93, 93 that stand on both sides, and a bottom portion 94 that is continuous from the lower ends of the vertical partitioning portions 93, 93. And the edge part 92a, 92a of the mounting beam 92 is joined to the vertical division part 93, 93 of this both sides by the position below the upper end by the thickness of the vertical grating 5 by welding. In other words, the mounting beam 92 is passed over and fixed to the upper part of the opening of the channel-shaped support 91. The riding beams 92 are arranged at predetermined intervals along the longitudinal direction of the groove-shaped support 91.

  In addition, the above-described channel-shaped support 91 is formed with anchor portions 95 and 95 protruding outward from the lower portion thereof. Even in this groove-shaped support body 91, it is assumed that a metal material such as steel or stainless steel is formed as a raw material, as in the first embodiment.

  This vertical grating supporting device 90 is positioned by fixing anchor portions 95, 95 by a fixed pile (not shown) on a base 88 on which the water flow channel 1 ″ is disposed, and concrete 18 around it. It is attached by embedding. A road surface material 19 is embedded in the surface layer around the water flow channel 1 ″ to form a road surface 9. As described above, the vertical grating support device 90 includes the channel-shaped support 91 to form a water flow channel 1 ″.

  Here, the vertical grating support device 90 is embedded so that the upper ends of both side walls 93, 93 of the groove-shaped support 91 coincide with the road surface 9. That is, the upper surface of the mounting beam 92 is located below the road surface 9 by the thickness of the vertical grating 5.

  By installing the vertical grating supporting device 90, the inner region of the groove-shaped support 91 becomes the water flow channel 1 ". That is, the vertical partitions 93 and 93 of the channel-shaped support 91 constitute the inner surface of the side wall constituting the water flow channel 1 ″, and the bottom 94 forms the floor of the bottom wall constituting the water flow channel 1 ″. Make a face. Then, the mounting beam 92 on which the vertical grating 5 is mounted is disposed above the opening of the water flow channel 1 ″. Therefore, it is possible to dispose the water flow channel 1 '' and the mounting beam 92 only by attaching the vertical grating supporting device 90, and the construction work can be easily performed as compared with the conventional configuration described above. In addition, the work time required for construction can be shortened.

  Even in the present embodiment, the vertical grating 5 is mounted on the mounting beam 92 of the vertical grating support device 90 in the same manner as in the first embodiment. The eye grating 5 can exhibit strength enough to withstand the load of a heavy vehicle such as an automobile. Further, similarly to the above-described embodiment 6, since there is no horizontal edge or the upper surface 4a of the side wall 4 below the vertical grating 5, there is an advantage that dust such as butts are not collected there.

  Note that the configuration of the ninth embodiment is the same as that of the first embodiment except for the configuration described above, and the same components are denoted by the same reference numerals and the description thereof is omitted.

  In the configuration of the first to ninth embodiments described above, each mounting beam is configured to have a square pipe shape, but the shape of the mounting beam can be variously set. Here, as the mounting beam, the horizontal edge of the support frame or the lower surface of the end abutting against the upper surfaces 4a, 4a of the side wall is set to the horizontal direction, and the vertical grating can be supported in a state along the horizontal direction. A shape that is substantially parallel to the upper surface of the mounting beam and the lower surface of the end portion may be used. For example, a U-shaped section having an opening at the bottom, a section having an I-shape, a section having a T-shape, and the like can be suitably used.

  Moreover, in the structure of Example 1-Example 9 mentioned above, the locking member which fixes the support apparatus for vertical gratings and the vertical grating can also be attached (illustration omitted). The vertical grating support device of the present invention is formed by passing a plurality of mounting beams and supporting the vertical gratings by the mounting beams, so that the vertical gratings and the mounting beams are directly fixed. The locking member can be attached relatively easily. Here, as this lock member, for example, a solidified portion that is solidified to the vertical grating, a U-shaped fitting portion that opens one side in the longitudinal direction and fits the riding beam, and the fitting portion Can be used that includes a screw-type locking means that clamps and fixes the mounting beam in a state in which the mounting beam is fitted. The lock member is fixed to the vertical grating in advance, and the vertical grating is slid in the longitudinal direction so that the fitting portion of the lock member is fitted to the mounting beam and fixed to the mounting beam by the locking means. . In this way, the vertical grating is fixed to the vertical grating support device by the lock member, thereby preventing the vertical grating from rattling and generating noise or jumping up due to the impact of passing an automobile. it can.

  Further, as another example of the above-described third embodiment, for example, the mounting beam has a square pipe shape whose overall length is substantially equal to the interval between the outer surfaces 4b and 4b of the side walls 4 and 4 of the groove member 2, and is plate-shaped. The supporting frame is joined so that the lower end of the supporting frame matches the lower end of the riding beam. And the fixing rod which hangs downward is joined to the outer surface of the support frame. Even in this configuration, the same effects as those of the third embodiment described above can be exhibited. On the other hand, the plate-like support frame may have a structure in which a through-hole that opens downward is formed in a lower portion thereof and the mounting beam is joined through the through-hole. Here, the left and right support frames are set to be substantially equal to the distance between the outer surfaces 4b and 4b of the side walls 4 and 4. That is, it is the structure which extended the distance between the support frames 71 and 71 of the structure of Example 7 mentioned above. Even in this configuration, the same effects as those of the third embodiment can be exhibited.

  The present invention is not limited to the above-described embodiments, and can be appropriately used within the scope of the gist of the present invention.
