Description

  The present invention relates to a groove lid, and more specifically, is installed on a road or the like, and the groove lid body is formed by forming a main member and a transverse member in a lattice shape in an outer frame, and the groove lid body is rattled in a receiving frame. The present invention relates to a gutter lid or a water collecting lid.

  Regardless of whether it is a general road or an expressway, the side of the road is usually provided with a side ditch or a buried drain pipe for draining rainwater. In addition, a drainage pipe is provided with a lid for collecting water at important points. These side groove lids and water collecting slab lids (hereinafter, these side groove lids and water collecting slab lids are collectively referred to as groove lids) accumulate large debris that clogs the grooves and the inside of the tube.

  Some of the above-mentioned groove lids use a concrete or iron plate groove lid body (lid), but in recent years there are many openings and good drainage, as well as clogging in the side grooves and in the water collecting chamber. A grating lid main body having an advantage that it can be easily confirmed is used frequently. This lattice-type groove lid body is formed by forming a main member and a transverse member in a lattice shape in an outer frame, and this groove lid body is dropped into a receiving frame attached with an anchor embedded in concrete. Alternatively, it can be opened and closed by a hinge mechanism, and further fixed by anchor bolts and nuts to constitute a mounting groove cover.

  By the way, among the above-mentioned groove lids, the type in which the groove lid main body is dropped into the receiving frame has a considerable gap between the groove lid main body and the receiving frame, and the type in which the hinge lid mechanism can be opened and closed is a groove. Since there is a considerable gap between the lid body and the receiving frame, and the hinge mechanism itself has a backlash, a car such as a bicycle or a car runs on the groove lid, or even if a person passes, In particular, in residential areas, this sound is annoying and problematic. On the other hand, as described above, the groove lid of the type in which the groove lid body is dropped into the receiving frame and fixed with anchor bolts and nuts can be firmly fixed and no sound is generated, but when removing dust etc., it is opened and closed. However, there are problems such as time consuming and poor workability.

  The present invention has been made in order to solve the above-described problems, and its purpose is to generate a sound such as rattling or rattling when driving a car or the like without causing much trouble in the operation of removing dust and the like. The present invention provides a groove cover that can be suitably applied to a road in a residential area.

In order to achieve the above object, according to a first aspect of the present invention, a groove lid according to claim 1 of the present invention is provided in such a manner that a groove lid body formed by forming a main member and a transverse member in a lattice pattern in an outer frame is attached to and detached from a rectangular frame. In the groove cover that can be provided, an auxiliary member that is provided near the bottom outer frame between the parallel main members of the groove cover main body and has a vertical through hole, and is provided rotatably in the through hole of the auxiliary member. a rotating shaft which is, this is provided at an end of the bottom side of the rotating shaft without the horseshoe, one end of the arcuate portion is formed thicker at its thick from an end portion of the other side A portion extending to one end formed is formed in a gradient, and a portion formed in a step shape having a relatively long depth is provided so as to belong to the portion formed in the gradient. And a clamping plate that is attached eccentrically to the anti-arc part, and the clamping plate rotates the pivot shaft. It is those that are formed so as be sandwiched the bottom plate portion of the receiving frame between the main member bottom surface to.

In the above structure, via the pivot shaft Mizofuta body rotatably provided without a horseshoe, one end of the arcuate portion is formed thicker at its thick from an end portion of the other side A portion extending to one end formed is formed in a gradient, and a portion formed in a step shape having a relatively long depth is provided so as to belong to the portion formed in the gradient. The clamping plate, which is attached with the moving shaft eccentric to the arcuate side, clamps the bottom plate of the receiving frame with the bottom surface of the main member by rotating the rotating shaft. As long as the tightening at the time is not released, the groove lid body does not rattle with the receiving frame, and it is possible to prevent sounds such as rattling and rattling during driving such as cars, and the groove lid body floats up from within the receiving frame, It can also be prevented from coming off. Further, the tightening can be easily released by rotating the rotating shaft, and the work of removing dust and the like can be performed without any trouble. In addition, because of noise prevention and easy cleaning, application to residential roads is expected. Note that the bottom plate portion to which the receiving frame is clamped can be formed by providing a cavity so that the clamping plate can enter and exit on the bottom surface side when the bottom frame is applied to the groove edge. Alternatively, it can be formed by projecting inwardly on the bottom plate portion of the receiving frame corresponding to the fastening plate.

  Further, the groove cover may be formed in a shape in which the end of the rotating shaft on the side of the counter-clamping plate can be engaged with the rotating tool (claim 2). Various means can be configured as means for attaching the rotating shaft to the through-hole of the auxiliary member. For example, the rotating shaft is a shaft member (may be a bolt) formed with a screw at one end, and its multiple ends (bolt A structure in which a fastening plate is welded and fixed to the head side) is inserted through the screw side from the bottom side of the through hole, and a nut is attached to the screw so that it can be rotated, or the tip of the screw part is square The bolt formed in the above is inserted into the through hole from above, and the rectangular portion is fitted into the rectangular hole of the clamping plate and then welded and fixed on the bottom surface side of the clamping plate. Regardless of the configuration, for rotation of the rotation shaft, a nut on the upper portion of the rotation shaft protruding above the auxiliary member or a box wrench at the tip of the rotation tool inserted from the top of the bolt is engaged. Will rotate. At this time, in the case of a nut, it is necessary to prevent rotation, but in addition to the rotation stop, the nut also plays a role of preventing the rotation shaft from coming off from the through hole. When a member having only a role is provided, a spanner hook, a groove, or the like that engages with the rotation tool is formed on the upper portion of the rotation shaft protruding above the member.

  Further, in the groove lid, it is preferable that the structure composed of the auxiliary member, the rotation shaft, and the clamping plate is provided at least one place on each of the left and right sides (Claim 3). As described above, that is, unless the tightening at the time of clamping the clamping plate is released, the groove lid body does not rattle with the receiving frame, and it is possible to prevent the sound of rattling and rattling from running such as a car. Etc. are obtained more effectively.

The shape of the tightening plate is preferably a horseshoe shape (such as a shape in which a part of the disk is cut out) because of the rotation to the thick part that becomes the tightening part during tightening and the thickness when the tightening is released This is because any rotation from the meat portion can be performed relatively smoothly using the gradient. Also, if the portion to be formed long number-step staircase-like with relatively depth is provided so as to belong to the portions formed gradient, tightening tends to work tightening so performed stepwise.

  As described above, with the groove lid according to the present invention, the groove lid body does not rattle between the receiving frame unless the tightening by the fastening plate is released, so that the sound of rattling and rattling sounds can be generated when the vehicle is running. Occurrence can be prevented. At the same time, it is possible to prevent the groove lid body from being lifted or removed from the receiving frame. Further, since the groove lid body can be opened by rotating the rotation shaft and releasing the tightening of the tightening plate, the operation of removing dust and the like can be performed without any trouble. Thus, noise prevention and easy cleaning make it possible to apply the present invention particularly to residential roads.

In the following description, front and rear refer to the front as viewed from the front, lower as the rear, and left and right refer to the drawing.

  The groove lid main body 1 has a main member 3 made of flat steel arranged at predetermined intervals with the width direction being up and down, end plates 4 are welded and fixed at both ends in the longitudinal direction, and are further crossed over the main member 3 to be screw bars. The horizontal members 5 are arranged at predetermined intervals like the main member 3 and are manufactured by welding so that the horizontal members 5 are pushed between the main members 3 and are flush with each other by projection welding. . The front and rear end plates 4 and the main members 3 at the left and right ends constitute an outer frame.

  On the bottom side near the front and rear end plates 4 between the main members 3 and 3 near the center of the groove lid main body 1, vertical through-holes 6 are formed at positions corresponding to substantially the center between the main members 3 and 3. The auxiliary members 7 and 7 made of flat steel are fixed by welding. A rotating shaft 11 having a fastening plate 8 welded and fixed at one end and a screw portion 9 and a spanner hook 10 formed at the other end is inserted into the through-hole 6 of the auxiliary member 7 from the bottom side. A nut 12 is fastened to the screw portion 9 so as to be rotatable. After the nut 12 is attached, the nut 12 is stopped by spot welding, not shown, or by a rotation stop pin. The anti-rotation position is a position where the bottom plate portion 22 constituting the receiving frame 2 described later can be sandwiched and tightened between the lower surface of the auxiliary member 7 and the upper surface of the tightening plate 8.

  Reference numeral 13 is a washer, and this washer 13 is provided so that it is more familiar than the nut 12 and can be easily rotated when the rotation shaft 11 is rotated. If there is, it becomes easier to tighten, and at the same time, it can be tightened by elastic force. Further, the shape of the spanner hook 10 of the rotating shaft 11 is not particularly limited, but a polygonal groove such as a hexagonal cross section corresponding to a box wrench generally used as a rotating tool. Alternatively, a protrusion shape is preferable.

  As shown in FIG. 4, the fastening plate 8 has a horseshoe shape in this example, and the edge portion of the arc portion 14 on the upper surface on the side where the rotating shaft 11 is attached is located on the one end portion 15 </ b> A side of the arc portion 14. It is formed so as to have a thick gradient and a thin wall between the other end 15B. And the rotating shaft 11 is eccentrically attached to the linear part (anti-arc part) 17 side. In addition to the said form, various forms can be assumed for the clamping board 8. FIG. For example, the gradient 16 is not a simple linear gradient, but is formed so as to have a linear gradient after the thick wall side is formed in several steps having a relatively long depth as shown in FIG. 4b. May be.

  The receiving frame 2 is squarely framed by front and rear receiving frame members 18 to 21 made of angle steel. Further, on the bottom surface of the bottom plate portion 22 at the position corresponding to the auxiliary member 7 of the front and rear receiving frame members 18 and 20 parallel to the transverse member 5 of the groove lid main body 1, a hollow forming member 23 having a shallow U-shaped cross section is formed. Are fixed by welding, and a cavity 24 is formed between the bottom surface of the bottom plate portion 22 and the bottom portion of the cavity forming member 23. The reason why the cavity forming member 23 is provided in this way is that it is easy to secure a cavity through which the fastening plate 8 can go in and out even when concrete is placed when the outer frame 2 is applied to a side groove or the like. Therefore, the cavity forming member 23 may be, for example, a single, flat tube having a flat cross section, in addition to a U-shaped member having a shallow bottom section.

  In the groove lid according to the present invention having the above-described configuration, the groove lid body 1 is installed in the receiving frame 2 in the following manner. That is, the central portion of the arc portion 14 of the fastening plate 8 provided in the groove lid main body 1 faces inward, and the groove lid main body 1 is dropped into the receiving frame 2 in this state. Next, the box wrench at the tip of a rotation tool (not shown) is engaged with the spanner hook 10 of the rotation shaft 11 and rotated from one end 15B to the other end 15A. By this rotation, the thick-walled end 15A of the arcuate portion 14 of the clamping plate 8 enters the cavity 24 in the bottom surface of the bottom plate portion 22 of the receiving frame 2, and the lower surface of the clamping plate 8 and the auxiliary member 7 or the main member 3 The bottom plate portion 22 of the receiving frame 2 is sandwiched between and tightened.

  In the state where the groove lid body 1 is installed in the receiving frame 2 as described above, the clamping plate 8 sandwiches the bottom plate portion 22 of the receiving frame 2 between the auxiliary member 7 or the lower surface of the main member 3 and tightens. Unless the tightening by the tightening plate 8 is released, the groove lid body 1 does not rattle between the receiving frame 2 and it is possible to prevent the rattling and rattling noises from being generated when the vehicle is traveling. At the same time, it is possible to prevent the groove lid body 1 from being lifted or removed from the receiving frame 2.

  Further, when opening the groove lid main body 1, the rotation shaft 11 can be rotated from the end portion 15 </ b> A to the end portion 15 </ b> B using a rotation tool, and the tightening plate 8 can be released to be opened. it can. In this way, the tightening by the tightening plate 8 can be easily released, so that the operation of removing dust and the like can be performed without any trouble.
