Description

  The present invention relates to an alignment device used for arranging groove members provided in a groove such as a drainage groove in a line.

  It is well known that the groove is composed of a U-shaped groove made of concrete. A groove cover receiving frame (groove member) for supporting the groove cover is installed on the U-shaped groove, and the upper opening of the groove is covered with the groove cover (for example, Patent Document 1). A plurality of groove lid receiving frames are arranged in a line along the longitudinal direction of the groove on the U-shaped groove.

  Such a groove lid receiving frame (hereinafter referred to as a groove member) a has a pair of left and right receiving bodies d and d provided at predetermined intervals by a plurality of beams f as shown in FIGS. A lid (not shown) is supported. The left and right receivers d, d are formed in an L-shaped cross section including a horizontal plate portion b mounted on the U-shaped groove k and a vertical plate portion c rising from the outer end of the horizontal plate portion b. Here, the left and right vertical plate portions c, c have a role of partitioning the inside and outside of the groove at the upper end of the groove h. Therefore, when installing the groove member a on the U-shaped groove k, the left and right vertical plate portions c, c of the groove members a, a lined up and down are respectively positioned and arranged in a line. is necessary. In order to perform such an arrangement easily and stably, for example, rectangular guide plate pieces g and g are formed on the outer surfaces of the vertical plate portions c and c at one end of the left and right vertical plate portions c and c. A configuration is known in which they are arranged so as to protrude along the same. In such a configuration, the end portions of the vertical plate portions c, c lined up and down can be aligned and arranged in a line by abutting the ends of the vertical plate portions c by the guide action of the left and right guide plate pieces g.

JP 2008-163684 A

  By the way, in the above-described conventional configuration in which the guide plate pieces are respectively provided on the left and right vertical plate portions, at least one guide plate piece is provided on each of the left and right vertical plate portions. The material cost and processing cost of a piece are required, and it is one factor which inhibits the cost reduction of a groove member. In addition, the guide plate piece has an excellent effect that the vertical plate portion can be easily positioned in a row as described above, and the guide plate piece is necessary if the groove members that have positioned the vertical plate portion are welded to each other. Sex is lost. For this reason, there is a demand for a groove member that can be easily arranged in a row and that can reduce the cost required for the groove member.

  The present invention proposes an alignment device that can position and arrange groove members having a pair of left and right vertical plates in a line.

  According to the present invention, groove members having a pair of left and right vertical plate portions arranged side by side along the longitudinal direction of the groove passage are arranged in a line by abutting the end portions of the vertical plate portions. The device body is folded with a hole width that allows the vertical plate portion to be inserted into a device body having a substantially V-shaped cross section formed longer than the distance between the pair of vertical plate portions. A pair of left and right slits that are notched so as to be orthogonal to the curved ridge edges are formed in parallel to each other with a space between the vertical plate portions in the left-right direction of the instrument body, and the left and right vertical plate portions that abut each other By aligning the respective end portions of the groove members with the left and right slits, the groove members are positioned and arranged in a line, thereby arranging and arranging the grooves.

  Here, as the bent ridge edge of the instrument body, an angular shape, a shape that curves relatively smoothly, and the like can be appropriately set. Furthermore, in the device for aligning and arranging according to the present invention, the length in the left-right direction of the device body is longer than the interval between the pair of vertical plate portions, and the left and right slits are formed at the interval between the vertical plate portions. Therefore, these dimensions are appropriately set according to the interval between the vertical plate portions of the groove member. Further, as the groove member, a groove lid receiving frame placed on the U-shaped groove, a saddle member having a U-shaped cross section constituting the groove, a plate-like member constituting the side wall of the groove, and the like are applied. Or a metal plate made of stainless steel or the like can be used. As a pair of left and right vertical plates constituting such a groove member, the height dimension varies from a relatively short one like the groove cover receiving frame to a relatively long one corresponding to the depth of the groove. There can be a configuration.

  In such a configuration, in the state where the end portions of the left and right vertical plate portions of the groove members lined up in the front and rear are respectively butted against each other, the left and right portions (hereinafter referred to as butted portions) where the end portions are butted together. By fitting the left and right slits respectively, the left and right vertical plate portions that are abutted in the front-rear direction can be positioned substantially in a straight line. Here, both end portions of the vertical plate portions that are abutted in the front and rear are inserted into the left and right slits, respectively. As a result, the left and right vertical plate portions that are abutted in the front-rear direction are positioned so that the left-right positions of the respective end portions are exactly aligned, and are arranged in a substantially straight line. For this reason, by using the aligning and arranging instrument of the present invention, it is possible to easily and stably perform the operation of arranging and arranging the groove members lined up in front and back in a line. As described above, when the aligning and arranging instrument according to the present invention is used, a guide plate piece is not required as in the conventional configuration described above. Furthermore, since the aligning / arranging instrument of the present invention is separate from the groove member, it can be removed and used again after the aligning / disposing operation, so that it can be used repeatedly one time. Therefore, by using the aligning / arranging instrument of the present invention, the groove members lined up in front and rear can be aligned and arranged in a line, and the above-described conventional guide plate piece is not required, and the cost applied to the groove members. Can be reduced.

  In the aligning and arranging instrument of the present invention described above, the slit has a hole width that is wider than the thickness of the vertical plate at the bent ridge edge of the instrument body, and extends from the bent ridge edge to both the front and rear sides. Therefore, a configuration is proposed in which the bent ridge edges are formed symmetrically in the front-rear direction so as to be gradually narrowed.

  According to such a configuration, the portion where the end portions of the vertical plate portions that are lined up in front and back are easily fitted into the slit from the center portion of the slit (the portion that intersects the bent ridge edge), and the bent ridge The left and right positions of the end portions can be easily matched by fitting them into the back of the slit so that the edge moves downward along the boundary between the end portions.

  Moreover, this structure can be used suitably when arranging the saddle-shaped groove member (see FIG. 7) having an inverted U-shaped cross section. Since the groove member having an inverted U-shaped cross section is formed by bending a steel plate (metal flat plate), there is an error in the distance between the left and right vertical plate portions. It is easy to produce a manufacturing error. Even in the case where such an error occurs, according to this configuration, since the hole width of the central portion of the slit is wider than the plate thickness of the vertical plate portion, the left and right vertical plate portions are inserted into the slit. It is possible to easily perform the work of arranging and arranging the groove members.

  Moreover, the vertical board part which comprises a groove member has the kind from which the board thickness differs. In order to correspond to such a range of different plate thickness, by setting the widest hole width in the center part of the slit (the part that intersects the bent ridge edge) and the narrowest hole width in the front and rear ends, It can be used for the operation of arranging and arranging the groove members of the vertical plate portions having different plate thicknesses.

  According to the aligning and arranging instrument of the present invention, as described above, by fitting the ends of the left and right vertical plate portions that face each other into the left and right slits, respectively, The left and right vertical plate portions that are abutted in the front-rear direction can be positioned in a substantially straight line, and the operation of arranging the front-rear groove member in a line can be performed easily and stably. Further, since the groove member can be arranged and arranged without the need for the guide plate piece as in the conventional configuration described above, the cost required for the guide plate piece is unnecessary and the cost for the groove member is reduced. can do.

Embodiments according to the present invention will be described below with reference to the accompanying drawings.
As shown in FIG. 1, the groove 1 is constructed by a U-shaped groove block 2 having a substantially U-shaped cross section, and the U-shaped groove block 2 is embedded in a row at a predetermined depth position on the ground. Built. Instead of the construction using the U-shaped groove block 2, the groove path 1 having a substantially U-shaped cross section can be formed by placing concrete in a formwork assembled on site.

  In the present embodiment, the longitudinal direction of the groove 1 is the front-rear direction, and the width direction of the groove 1 (the direction orthogonal to the longitudinal direction) is the left-right direction.

  A plurality of groove members 4 having a pair of left and right groove lid receivers 5, 5 are provided on the left and right side walls 3, 3 of the U-shaped groove block 2 constituting the groove 1. 1 are arranged in a line along the longitudinal direction. Here, the left and right groove lid receivers 5 and 5 include a horizontal plate portion 6 placed on the upper surface of the side wall 3 and a vertical plate portion 7 standing from the outer end of the horizontal plate portion 6. In addition, a belt plate material made of a metal such as steel or stainless steel is bent into a L-shaped cross section and has a predetermined length. Further, a plurality of mounting beams 8 are passed to the left and right groove lid receivers 5 and 5 at predetermined intervals in the longitudinal direction of the groove member 4. Each mounting beam 8 is welded with both end portions mounted on the left and right horizontal plate portions 6 and 6. By this mounting beam 8, the left and right gaps between the left and right groove lid receivers 5, 5 are determined, and the gap is set according to the gap between the left and right side walls 3, 3 of the U-shaped groove block 2. . Such a groove member 4 is formed by integrating left and right groove lid receivers 5 and 5 with the left and right vertical plate portions 7 and 7 being parallel to each other. The groove member 4 is provided with fixing means (not shown), and is fixed to the U-shaped groove block 2 by the fixing means.

  A groove cover 10 is supported on the mounting beam 8 of the groove member 4, and the groove path 1 is covered with the groove cover 10. In addition, the vertical dimension of the vertical plate portion 7 of the groove member 4 is set so that the height dimension thereof substantially matches the total dimension of the thickness of the riding beam 8 and the thickness of the groove lid 10.

  As the groove lid 10, vertical grating is applied. This vertical grating is composed of a plurality of main bars (not shown) arranged in parallel at a predetermined interval along the longitudinal direction of the groove 1 and two side bars passed across the longitudinal ends of each main bar. (Not shown) and a cross bar (not shown) passed between the side bars perpendicularly to each main bar at a predetermined interval. The vertical grating has a width that is set to be slightly shorter than the distance between the left and right vertical plate portions 7 of the groove member 4, and by arranging a predetermined number in a line, the upper portion of the groove 1 Cover the opening.

  As described above, a predetermined number of such groove members 4 are arranged in a line on the U-shaped groove block 2 and are fixed to the U-shaped groove block 2. Here, the respective groove members 4 arranged in the front-rear direction need to be aligned and arranged so that the left and right vertical plate portions 7, 7 are arranged in a substantially straight line. The inner and outer sides of the groove 1 are partitioned by the left and right vertical plate portions 7 and 7 arranged in this way.

Next, the alignment / arrangement instrument 11 according to the main part of the present invention will be described.
As shown in FIGS. 2 and 3, the aligning / arranging instrument 11 includes an instrument body 12 having a substantially flat V-shaped cross section formed by bending a rectangular flat plate from the center thereof. Slits 13 are formed. Here, the instrument body 12 is formed by bending a rectangular flat plate made of a metal such as steel or stainless steel into a substantially V-shaped cross section, and tilts forward and backward from the bent ridge edge 15. The inclined plate portions 16 and 16 are formed so as to be symmetrical in the front-rear direction. And the instrument main body 12 is set so that the length dimension of the left-right direction along the bending ridge edge 15 may become longer than the space | interval of the right-and-left vertical board parts 7 and 7 which comprise the above-mentioned groove member 4. FIG. (See FIG. 5). The bent ridge edge 15 is formed in a curved shape so that the lower edges of the front and rear inclined plate portions 16, 16 are coupled relatively smoothly.

  The slits 13, 13 are formed in a pair on the left and right ends of the instrument body 12 with a space between the left and right vertical plate portions 7, 7 of the groove member 4 (see FIG. 5). The left and right slits 13 and 13 are notched in the front and rear inclined plate portions 16 and 16 so as to be substantially orthogonal to the bent ridge edge 15 and are parallel to each other. These left and right slits 13, 13 penetrate the upper and lower sides of the instrument main body 12, so that the left and right vertical plate portions 7, 7 of the groove member 4 can be fitted simultaneously. In addition, the slit 13 is formed so that the hole width is the widest at the portion where the bent ridge edge 15 intersects and gradually narrows toward the front and rear ends, and the bent ridge edge 15 is the center. It forms a symmetrical form. And the hole width of the center part which cross | intersects the bending ridge edge 15 of the slit 13 is set to the width | variety wider than the plate | board thickness of the above-mentioned vertical board part 7, and the hole width of front and rear both ends is narrower than this center part Set to width. For example, the slit 13 has a hole width at the center portion set to 1.2 times that of the vertical plate portion 7, and the hole widths at both front and rear ends are equal to or less than the plate thickness of the vertical plate portion 7 (0.9 times the plate thickness, etc.) ). In this case, the slit 13 is easy to fit the vertical plate portion 7 at the central portion thereof, and the vertical plate portion 7 cannot be fitted to both front and rear ends. In addition, the hole width of the slit 13 is not limited to this, and can be set as appropriate.

  In this arrangement and arrangement instrument 11, when the left and right vertical plate portions 7 and 7 are respectively inserted into the left and right slits 13 and 13, the region to be inserted at the end 7 a of each vertical plate portion 7 is widened to some extent. As described above, the angle between the front and rear inclined plate portions 16, 16, the width of the inclined plate portion 16, the length of the slit 13 and the like are set (see FIG. 4).

  The aligning / arranging instrument 11 of this embodiment is used for aligning the groove members 4, 4 that are mounted on the U-shaped groove block 2 and lined up and down in a line. That is, the groove members 4, 4 arranged in the front-rear direction are mounted on the U-shaped groove block 2 so that the end portions of the left and right vertical plate portions 7, 7 face each other. In this state, as shown in FIG. 4A, the left and right portions (butting portions) where the end portions 7a and 7a of the left and right vertical plate portions 7 and 7 are abutted with each other are the centers of the left and right slits 13 and 13. The alignment device 11 is fitted from above so as to be fitted into the portion. Here, as shown in FIG. 4 (B), the aligning / disposing instrument 11 is placed on the abutting portion so that the bent ridge edges 15 are substantially along the boundary between the front and rear vertical plate portions 7 and 7 where they are abutted with each other. Fit together. As a result, as shown in FIGS. 4B, 5 and 6, the left and right slits 13 and 13 have both end portions 7a and 7a of the vertical plate portions 7 and 7 abutted on the front and rear, respectively. Since they are fitted approximately equally, the left and right positions of the end portions 7a and 7a can be made to coincide with each other accurately. Thus, by inserting the aligning / arranging device 11 into the abutting portion, the left and right vertical plate portions 7 and 7 which are abutted in the front-rear direction can be aligned substantially in a straight line, and the front and rear groove members 4 and 4 are aligned. Can be arranged in a line.

  When arranging such groove members 4, 4, the aligning and arranging instrument 11 is wider than the plate thickness of the vertical plate portion 7 at the center where the left and right slits 13, 13 intersect the bent ridge edge 15. Since it is formed with a wide hole width (see FIG. 3), it can be easily fitted from the central portion to the abutting portion of the front and rear vertical plate portions 7 and 7. Furthermore, if the vertical positions of the vertical plate portions 7 and 7 that are abutted in front and rear are adjusted to some extent before fitting the alignment device 11, it can be easily adjusted to the right and left positions that can be inserted from the center portion of the slit 13. It is. This can be said to be an advantage of the present configuration in which the end portions 7a and 7a of the front and rear vertical plate portions 7 and 7 are fitted together from the center portion of the slit 13. Further, since the left and right slits 13 and 13 are formed so that the hole width gradually decreases from the central portion toward the front and rear ends (see FIG. 3), the front and rear vertical plate portions 7 and 7 are abutted. By adjusting the position of the front and rear vertical plate portions 7 and 7 so that the portion fits into the back of the slit 13, the front and rear vertical plate portions 7 and 7 can be aligned in a substantially straight line (FIG. 5, FIG. 5). 6). By using the aligning / disposing instrument 11 in this way, the groove members 4 and 4 arranged in the front and rear direction can be aligned and arranged in a line relatively easily and stably.

  When aligned and arranged in this way, the groove members 4 and 4 are welded together (not shown), and then the aligning and arranging instrument 11 is removed. Similarly, by repeatedly performing the arrangement of the groove members 4 in a line using the aligning and arranging instrument 11, a plurality of groove members 4 can be arranged in an array (see FIG. 1). Further, if the groove member 4 is disposed using the aligning / disposing instrument 11, the above-described conventional configuration (see FIGS. 8 and 9) in which the guide plate piece is disposed at one end of the groove member is not required. Therefore, the cost of the guide plate piece becomes unnecessary, and the cost applied to the groove member can be reduced. Since the aligning / disposing instrument 11 can be used many times by one, the cost reduction effect described above is extremely large as compared with the conventional configuration in which a guide plate piece is required for each groove member.

  Further, in the groove member 4, the interval between the left and right vertical plate portions 7 and 7 is determined by the width of the groove lid 10, the width of the U-shaped groove block 2, and the like. It is fixed. Therefore, by preparing the aligning and arranging instrument 11 that matches the predetermined interval between the vertical plate portions 7 and 7, it can be applied to various groove member 4 arranging operations.

  In addition, since there are also different types of groove members in which the vertical plate portions have different plate thicknesses, it is necessary to prepare an alignment arrangement instrument 11 that can correspond to each of these different plate thickness configurations. You can also. That is, the slit 13 is set so that the range of each plate thickness set in the vertical plate portion is included in the range of the hole width that changes from the central portion of the slit 13 to the front and rear ends. Thereby, it can apply to the arrangement | positioning operation | work of the groove member provided with the vertical board part of various board thickness by one type of arrangement | positioning arrangement | positioning instruments 11.

  In the above-described embodiment, the groove member 4 mounted on the U-shaped groove block 2 has been described. However, as shown in FIG. it can. The groove member 34 having an inverted U-shaped cross section is formed by bending a steel plate or a flat plate made of stainless steel, and includes a bottom plate portion 36 and vertical plate portions 37 and 37 standing vertically from both left and right ends thereof. It is configured. Furthermore, a plurality of mounting beams 38 are passed and fixed to the upper portions of the left and right vertical plate portions 37, 37 at predetermined intervals in the longitudinal direction. By arranging a plurality of groove members 34 in a line along the longitudinal direction, the groove path 31 is constructed, and the groove cover 31 is covered by the groove cover 10 supported by the mounting beam 38 (not shown). ) When arranging the groove members 34 in a line, the above-described alignment and placement instrument 11 of this embodiment can be applied. Here, as the aligning / disposing instrument 11, the left and right slits 13, 13 are formed by cutting away the left and right vertical plate portions 37, 37. When the groove member 34 is arranged using the aligning / disposing instrument 11, it is performed in the same manner as in the above-described embodiment. That is, the end portions 37a, 37a of the left and right vertical plate portions 37, 37 of the groove members 34, 34 arranged in the front-rear direction are brought into contact with each other, and the left and right slits of the aligning / disposing instrument 11 are placed in the left and right portions. Fit 13 and 13 respectively. As a result, the left and right vertical plate portions 37, 37 abutted in the front-rear direction can be aligned substantially in a straight line, and the front-rear groove member 34, 34 can be aligned in a line. Further, the groove member 34 is likely to cause a manufacturing error in the dimensional shape of the left and right vertical plate portions 37, 37. Such errors can be absorbed by the wide central portion of the slit 13 according to the aligning and arranging instrument 11 of the present embodiment. That is, even in the case of having the error, the slit 13 can fit the left and right vertical plate portions 37, 37, and the groove member 4 can be aligned. As described above, by using the aligning / arranging instrument 11 of the present embodiment, the groove members 34 having an inverted U-shaped cross section can be easily and stably aligned and arranged in a line, and the same effects as those of the above-described embodiment. Play.

  In this invention, it is not limited to the Example mentioned above, About the structure other than the above-mentioned Example, it can change and implement suitably within the range of the meaning of this invention. For example, the aligning and arranging instrument 11 of the present embodiment is made of metal such as steel, but may be made of FRP or the like.
