Description

  The present invention relates to a groove cover for fixing groove cover receiving frames that support groove covers such as color pavement groove covers and grating groove covers that are deposited on groove paths such as U-shaped grooves on the left and right side walls of the groove paths. The present invention relates to a receiving frame fixing device.

  As shown in FIG. 10, the groove cover receiving frames a and a which are disposed on the left and right side walls e and e constituting the groove d such as a U-shaped groove and support the groove cover f are perpendicular to the horizontal edge b. In general, the groove lid receiving frames a and a are arranged on the side walls e and e at the vertical edge c of each groove lid receiving frame a. A plurality of anchors g attached at a predetermined interval are embedded in a concrete h placed on the outer side of the side walls e and e and solidified, whereby the groove lid receiving frames a and a are inserted through the anchors g. Is fixed on the side walls e and e.

  In the construction of such a general groove lid receiving frame a, a, since the groove lid receiving frame a, a is easily displaced by the flow pressure of the concrete h when the concrete h is placed, the groove lid receiving frame a, a It was necessary to take measures to prevent misalignment such as placing a heavy stone on the top or placing it on the groove lid receiving frames a and a with the groove lid f covered with a sheet or the like so as not to get dirty. .

  On the other hand, it is also known that a fixing member is provided on the groove lid receiving frame a, as the above-described convenience for preventing the slippage from being required. This is related to the manufacture and sale of the applicant of the present application. As shown in FIG. 11, a plurality of fixing brackets j made of a cast product having a substantially U-shaped cross section are attached to the lower surface of the horizontal edge b of the groove cover receiving frame a. As shown in FIG. 12, each fixing bracket j is disposed at a predetermined interval in the longitudinal direction of the groove cover receiving frame a. A bolt p is screwed to the side piece m located outside the side wall e among the two opposing side pieces m, n projecting downward from the fixing metal j, and each fixing metal j is placed on the upper side of the side wall e. In the state where the bolt p is externally fitted, the bolt p is screwed in the tightening direction, and the tip of the bolt p is brought into pressure contact with the outer surface of the side wall e. The groove lid receiving frame “a” is configured to be fixed to the side wall “e” through the clamping action (see Non-Patent Document 1).

Since the fixing bracket j of the groove lid receiving frame a having such a configuration is a cast product, the angle formed by the top wall portion t and the side piece n positioned on the inner side is determined by the upper surface and the inner surface of the side wall e. It can be formed with high accuracy according to the angle formed, and excellent rigidity peculiar to a cast product can be obtained, so that when the bolt p is tightened, the side piece n is not deformed so as to open sideways, The side piece n can be brought into surface contact with the inner surface of the side wall e accurately. Accordingly, the groove lid receiving frame a can be fixed to the side wall e without backlash, and the left and right groove lid receiving frames a, a can be held at a predetermined interval corresponding to the lateral width of the groove lid f.

  By the way, in the above-mentioned prior art, since the fixing metal fitting j is a cast product, its welding strength is lowered when welding is used for assembling means with the groove lid receiving frame a formed of steel, stainless steel or the like. Assembling means using a countersunk screw k is applied. The assembling means using the countersunk screw k applies a screw hole forming process to the top wall portion t of the fixing bracket j, while the horizontal edge portion of the groove lid receiving frame a. The plate screw k must be subjected to the insertion hole forming process of the countersunk screw k and the conical counterbore for accommodating the head of the countersunk screw k, and the countersunk screw k inserted from above into the insertion hole of the groove cover receiving frame a Is required to be screwed into the screw hole of the fixing bracket j and tightened. For this reason, there is a problem that the preparation process and the assembly work for assembly take time and cost is high.

  Further, as described above, the plurality of fixing metal fittings j attached to the groove lid receiving frame a are arranged at predetermined intervals in the longitudinal direction of the groove lid receiving frame a, so that the groove lid receiving frame a is grooved by the fixing metal fitting j. As shown in FIG. 12, a gap s is formed between the lower surface of the groove cover receiving frame a and the upper surface of the side wall e, as shown in FIG. The concrete provided and the sand of the sand cushion laid at the lower part of the paving material will flow out into the groove d from the gap s. For this reason, the packing which fills the said clearance gap s has to be affixed beforehand to the lower surface of the groove lid receiving frame a, and the cost was further increased by the effort and material cost.

  The present invention solves this problem, and can be easily and reliably fixed to the side wall of the groove, and there is no gap between the upper surface of the side wall in the fixed state. An object of the present invention is to provide a fixing device for a groove lid receiving frame that has a simple structure and is easy to manufacture and can reduce costs.

  The present invention includes a horizontal edge that supports the side edge of the groove lid, and a vertical edge that rises from the outer end of the horizontal edge along the side surface of the groove lid, and the upper surfaces of the left and right side walls that constitute the groove In the groove lid receiving frame mounted on the horizontal edge portion and disposed in a pair of left and right along the longitudinal direction of the groove, a horizontal screw hole is provided, and the groove cover from the left and right groove lid receiving frames is provided. A plurality of anchors that are respectively suspended downward along the outer surface of the side wall of the groove cover and arranged at predetermined intervals in the longitudinal direction of the groove cover receiving frame, and screwed into the screw holes of the anchors, respectively, A plurality of screw rods press-contacted to the outer surface of the side wall of the groove and substantially aligned with the positions of the anchors, both ends can be separated from the inner surfaces of both vertical edge portions of the left and right groove cover receiving frames. Fixing a groove lid receiving frame comprising a plurality of support rods joined and passed between both vertical edges It is the location.

  Here, a metal such as steel or stainless steel is preferably used as the material of the groove lid receiving frame, and a band plate material made of a metal excellent in weldability with the groove lid receiving frame can be used as the anchor. Thus, by using a metal excellent in mutual weldability for the groove lid receiving frame and the anchor, the groove lid receiving frame and the anchor can be easily joined with high strength by welding, and the cost can be reduced. Further, the horizontal screw hole provided in the anchor can be formed by tapping the strip material. In addition, the bearing rod is removed after construction, and a metal rod made of metal having excellent weldability with the groove lid receiving frame is used, and only a part of its end is welded to the inner surface of the vertical edge. By doing so, they can be joined in a separable manner.

  In the fixing device for a groove lid receiving frame having the above-described structure, each support rod is a thin strip having a predetermined vertical width, and the vertical width is arranged in the vertical direction at an upper position of the vertical edge. Proposed configuration is proposed.

  As described above, the present invention is a groove lid receiving frame in which a horizontal edge portion is mounted on the upper surfaces of the left and right side walls constituting the groove, and the pair of right and left are disposed along the longitudinal direction of the groove. A plurality of screw holes provided in the horizontal direction and vertically suspended from the left and right groove cover receiving frames along the outer surface of the side wall of the groove, and disposed at predetermined intervals in the longitudinal direction of the groove cover receiving frame. An anchor, a plurality of screw rods that are screwed into screw holes of the respective anchors, and whose tips are pressed against the outer surface of the side wall of the groove, and are arranged substantially in line with the arrangement positions of the anchors; Since it is a fixing device for a groove lid receiving frame comprising a plurality of support rods that are separably joined to the inner side surfaces of both vertical edge portions of the left and right groove lid receiving frames and are inserted between both vertical edge portions, Left and right groove lid receiving frames that are integrally connected by a plurality of support rods passed between both vertical edges constitute a groove path On the left and right side walls, the screw rods screwed into the screw holes of the respective anchors are screwed in the tightening direction, and the tips thereof are pressed against the outer side walls of the grooves, thereby The left and right groove cover receiving frames can be easily fixed on the left and right side walls through the clamping action of the left and right screw rods pressed against the outer surface. Here, when the screw rod is screwed in the tightening direction and its tip is brought into pressure contact with the outer surface of the side wall of the groove, the anchor to which the screw rod is engaged tilts outward as the tightening force increases. The groove lid receiving frame is subjected to a force to rotate the groove lid receiving frame inwardly with the inner edge of the horizontal edge in contact with the upper surface of the side wall as a fulcrum and tilt the vertical edge inwardly. However, the support rods passed between the vertical edge portions of the left and right groove lid receiving frames are arranged so as to substantially coincide with the arrangement positions of the anchors. Through the tensioning action, it is possible to prevent inclined deformation in the inner direction of the vertical edge. As a result, the screw rod can be strongly tightened, and the groove lid receiving frame can be securely fixed on the side wall. Further, when the groove lid receiving frame is fixed on the side wall as described above, the horizontal edge portion of the groove lid receiving frame is in contact with the upper surface of the side wall, so that the gap between the groove lid receiving frame and the upper surface of the side wall is provided. In this case, no gap is generated, and no packing for filling the gap used in the conventional configuration is required. Furthermore, since the anchor and the support rod can be attached to the groove lid receiving frame by welding, the manufacturing is easy and the structure is simple. It can be reduced and short-term delivery is possible.

  Further, in the configuration in which the support rod is a thin strip having a predetermined vertical width and the vertical width is oriented in the vertical direction and disposed at the upper position of the vertical edge portion, L Costs can be reduced compared to the use of angled and cylindrical materials, and the thickness is curved in the thickness direction by placing the vertical width along the vertical direction at the upper position of the vertical edge. Even if it is a thin strip material that is easy to do, a high tensile strength that can resist the force of inclining the vertical edge portion inward can be generated.

Below, the 1st Example of the fixing device of the groove cover receiving frame concerning this invention is described based on FIGS.
As shown in FIG. 1, the groove 1 is formed in a substantially U-shaped cross section by placing concrete on a U-shaped groove block or a formwork assembled on site, and left and right side walls constituting the groove 1 A pair of left and right groove cover receiving frames 3, 3 are disposed on the upper surfaces of 2, 2 along the longitudinal direction of the groove 1. Each of the groove lid receiving frames 3 and 3 includes a horizontal edge portion 5 that supports the side edge of the groove lid 4, and a vertical edge portion 6 that rises from the outer end of the horizontal edge portion 5 along the side surface of the groove lid 4. A metal plate made of a metal plate such as steel or stainless steel having a L-shaped cross section is used. The groove cover receiving frames 3 and 3 in the first embodiment are applied to the groove cover 4 for color pavement having a relatively large thickness, and the vertical dimension of the vertical edge 6 is laid on the outer side. The size is slightly larger than the thickness of the color pavement block 7.

  The left and right groove lid receiving frames 3, 3 are provided with a plurality of anchors 8 respectively suspended downward along the outer surfaces of the side walls 2, 2 of the groove 1, as shown in FIGS. As described above, the groove lid receiving frames 3 and 3 are arranged at predetermined intervals in the longitudinal direction. Each anchor 8 is made of the same metal strip as the material of the groove lid receiving frames 3, 3, and is fixed to each groove lid receiving frame 3, 3 by welding the upper end to the outer surface of the vertical edge portion 6. Thus, by making the groove cover receiving frames 3 and 3 and the anchors 8 of the same material metal, they can be easily joined with high strength by welding, and the cost can be reduced as compared with screwing. Further, in the vicinity of the lower end of each anchor 8, a horizontal screw hole 9 is provided by tapping, and a screw rod 10 made of a bolt is screwed into the screw hole 9. The screw rod 10 is brought into pressure contact with the outer surface of the side wall 2 of the groove 1 by screwing in the tightening direction. The screw rod 10 has a relatively long length, and is anchored by being embedded and solidified in the concrete 11 for solidification placed on the outer side of the side walls 2 and 2. 8 together with the anchor action.

  Further, between the vertical edge portions 6 and 6 of the left and right groove lid receiving frames 3 and 3, as shown in FIGS. The support rods 12 are respectively arranged, and the left and right groove lid receiving frames 3, 3 are spaced by a plurality of support rods 12 interposed between the two vertical edges 6, 6, corresponding to the lateral width of the groove lid 4. Are connected together. Each bearing rod 12 is made of a thin strip material having the same vertical length as the material of the groove lid receiving frames 3 and 3, and both ends are inner surfaces of both vertical edges 6 and 6 of the groove lid receiving frames 3 and 3. Are separably joined. That is, since each bearing rod 12 is removed after construction, as shown in FIG. 4, the end portion of each bearing rod 12 is in contact with the vertical edge portion 6 in an orthogonal state. It joins via the bead part z which welded only the one side, and can isolate | separate easily from the vertical edge part 6 by twisting the edge part vicinity with appropriate tools, such as a pliers. Further, each bearing rod 12 is disposed at an upper position of the vertical edge portions 6 and 6 with the vertical width thereof extending along the vertical direction. Thereby, even if it is the bearing rod 12 which consists of a thin-shaped strip board material which is easy to curve in the thickness direction, it can be made to produce high tensile strength.

  Further, as shown in FIG. 2 (b), diagonal reinforcing rods 13 and 13 are detachably joined to the horizontal edge portions 5 and 5 of the left and right groove lid receiving frames 3 and 3, respectively. The reinforcing rods 13 and 13 prevent relative displacement along the longitudinal direction of the groove lid receiving frames 3 and 3 and are removed after the construction.

Next, construction of the groove lid receiving frames 3 and 3 will be described.
First, the horizontal edge portions 5 and 5 of the groove lid receiving frames 3 and 3 integrally connected by the plurality of support rods 12 with the screw rods 10 of the respective anchors 8 retracted in advance as shown in FIG. And on the side walls 2 and 2. Next, in this state, the screw rod 10 screwed into the screw hole 9 of each anchor 8 is screwed in the tightening direction, and the tip thereof is brought into pressure contact with the outer surfaces of the side walls 2 and 2 of the groove 1. As a result, a clamping action is generated by the left and right screw rods 10 pressed against the outer surfaces of the left and right side walls 2, 2. Can be fixed easily.

  Here, if a plurality of bearing rods 12 are disposed at positions away from the anchors 8, the screw rods 10 are screwed in the tightening direction, and the tips thereof are attached to the outer surfaces of the side walls 2 and 2 of the groove 1. As shown in FIG. 6, when the pressure contact is increased, the anchor 8 to which the screw rod 10 is screwed is tilted outward and the horizontal edge that contacts the upper surfaces of the side walls 2 and 2 is increased. The groove lid receiving frames 3 and 3 are rotated inward with the inner ends of the portions 5 and 5 as fulcrums, and the vertical edge portions 6 and 6 are inclined inward. In the present invention, The support rods 12 passed between the vertical edge portions 6 and 6 of the left and right groove lid receiving frames 3 and 3 are arranged so as to substantially coincide with the arrangement positions of the anchors 8. It is possible to prevent the vertical edges 6 and 6 from being inclined inwardly through the tensioning action of the flange 12.As a result, the screw rod 10 can be strongly tightened, and the groove lid receiving frames 3, 3 can be securely fixed on the side walls 2, 2. Further, when the groove lid receiving frames 3, 3 are fixed on the side walls 2, 2, the horizontal edge 5 of the groove lid receiving frames 3, 3 is in contact with the upper surface of the side walls 2, 2. As a result, the conventional gap s (see FIG. 12) does not occur between the groove lid receiving frames 3 and 3 and the side walls 2 and 2 and the packing for filling the gap used in the conventional configuration is used. Is unnecessary.

  Then, after fixing the groove cover receiving frames 3 and 3 on the side walls 2 and 2 of the groove 1 as described above, the concrete 11 and 11 for consolidation (see FIG. 1) is placed around the lower portion of each anchor 8. To do. At this time, the groove lid receiving frames 3 and 3 are fixed through the clamping action by the screw rods 10 on both the left and right sides as described above, so that the positional displacement occurs due to the flow pressure of the concrete 11 and 11 for consolidation. There is no. And after this concrete 11 for hardening is hardened, the groove cover 4 (refer FIG. 1) can be adhere | attached by removing each support rod 12. FIG. Here, when each support rod 12 is removed, the clamping action by the screw rods 10 on both the left and right sides disappears, but the groove lid receiving frames 3 and 3 are connected via the anchors 8 fixed to the fixing concrete 11 and 11. It will be held firmly on the side walls 2 and 2. Further, after the consolidation concrete 11, 11 is cured, as shown in FIG. 1, a color pavement block 7 is laid around the groove 1, and a screw rod 10 of each anchor 8 is used for the color pavement. By being positioned below the block 7, the color paving block 7 can be laid close to the vertical edges 6 and 6.

  In the first embodiment described above, the case where the metal of the same material as that of the groove cover receiving frames 3 and 3 is used for the anchor 8 and the support rod 12, but the anchor 8, the support rod 12, and the groove cover receiving frame 3 are It is possible to use a combination of metals having excellent weldability such as steel and stainless steel as appropriate. That is, the groove lid receiving frame 3 is made of stainless steel, and the anchor 8 and the bearing rod 12 are made of steel, or the groove lid receiving frame 3 and the anchor 8 are made of stainless steel, the bearing rod 12 is made of steel, and the groove lid receiving frame 3 is made of steel. 8 and the support rod 12 can be made of stainless steel, and the groove lid receiving frame 3 and the anchor 8 can be made of steel, and the support rod 12 can be made of stainless steel.

  7 to 9 show a second embodiment, and the groove cover receiving frames 3 and 3 in this second embodiment are applied to the groove cover 4 made of a relatively thin grating, and have a vertical edge. The height dimension of the parts 6 and 6 is extremely smaller than the thickness of the color paving block 7 laid on the outer side.

  In this way, in the case of the groove lid receiving frames 3 and 3 where the vertical edge portions 6 and 6 are small in height, the plurality of anchors 8 and 8 respectively suspended downward from the groove lid receiving frames 3 and 3 are colored. Locking portions 8 ′ and 8 ′ that are formed in a relatively long shape so as to reach the concrete for consolidation 11 and 11 that are placed below the paving block 7 and project laterally at the lower end thereof. Is provided. A predetermined anchoring action can be generated by embedding the locking portions 8 ′ and 8 ′ in the solidifying concrete 11 and 11 and solidifying them. Further, in this way, if each anchor 8 is long, it is easy to bend and the support strength is lowered. Therefore, the screw rod 10 screwed to each anchor 8 is near the upper portion of the anchor 8 near the groove cover receiving frame 3. Arranged in position. Further, each screw rod 10 uses a relatively short screw rod having a hexagonal hole 14 (see FIG. 8) for screwing operation at the outer end. As a result, as shown in FIG. 7 can be laid close to the vertical edges 6 and 6.

  Other configurations are the same as those of the first embodiment described above, and the same parts are denoted by the same reference numerals and redundant description is omitted. The groove cover receiving frames 3 and 3 in the second embodiment are also constructed in the same manner as in the first embodiment, and the above-described effects can be obtained.

  As described above, in the present invention, the groove 1 can be fixed to the side walls 2 and 2 easily and reliably, and a gap is formed between the upper surfaces of the side walls 2 and 2 in the fixed state. Therefore, the packing for filling the gap is unnecessary, and the anchor 8 and the support rod 12 can be attached to the groove cover receiving frames 3 and 3 by welding, so that they are easy to manufacture and have a simple structure. Together with this, the cost can be greatly reduced as compared with the conventional configuration, and short-term delivery is possible.
