[Problems to be solved by the invention]
The above known examples of Patent Document 1 and Patent Document 2 are based on the precondition that the groove cover is standardized and mass-produced and continuously laid in a straight groove. While it is impossible to lay continually in many existing groove bends, it is necessary to manufacture a specially-designed groove cover that is individually aligned with each individual bend groove, and the cost increases. There are difficulties in construction problems such as difficulty in laying due to the dimensional mismatch between the bending shape of the groove at the construction site and the "groove lid for the bending portion specially produced in advance based on the design drawing", and the occurrence of looseness in the groove cover.
[0006]
Furthermore, since the thing of patent document 1 is a bolt fastening interconnection means, the removal operation | work at the time of laying construction and a maintenance becomes complicated, and the thing of patent document 2 attaches the square tongue piece board of one side to the other side. Because it is simply inserted and set in the tongue plate slit, there is no interlocking means in the longitudinal direction of adjacent groove lids, and it is impossible to regulate the mutual distance between adjacent groove lids when laying in the groove become.
[0007]
Therefore, there is a possibility that an abnormality of an excessive set of mutual intervals due to a mistake in continuous laying may occur, and if the abnormal gaps between the groove lid groups laid in the groove length direction are accumulated and appear at one place, the groove of the continuous laying posture is obtained. There is a problem that the lid cover function is lost due to the intermediate disengagement of the lid group.
[0008]
The present invention provides an interconnecting structure for groove lids that eliminates the above-mentioned problems of the prior art.
[0009]
[Means for Solving the Problems]
The interconnection structure of the groove lids of the present invention that solves the above technical problems is “having a reverse U-shape in cross section with side plates suspended from both sides of the long flat lid plate in series with the upper end of the groove body. In the groove cover to be continuously laid, at one end in the longitudinal direction, the auxiliary cover plate of the semicircular tongue protruding from the back surface of the cover plate and the auxiliary cover plate from the lower end portion of the side plate are parallel to the auxiliary cover plate, and A first connection plate having a connection pin standing upright at the center of a semicircular shape is projected, and the other end in the longitudinal direction can be overlapped with the first connection plate, and the connection pin The second connecting plate is provided with an oblong pin hole provided in the longitudinal direction, and can be continuously laid in a straight bending posture by detachably connecting and locking the first connecting plate and the second connecting plate of the adjacent groove cover. It is characterized by the “structure made up”
[0010]
That is, the groove lid interconnection structure of the present invention having the above-described configuration is such that the connection pin of the first connection plate at one side end of the pair of groove lids to be connected to each other is the oblong hole of the second connection plate at the other end. It is inserted into the pin hole of the groove and connected and locked to each other so as to be relatively movable with a slight stroke in the groove length direction, and the semicircular auxiliary lid plate on one side can be superposed under the lid plate on the other side The pair of groove lids can be connected and set in a straight shape or a bent shape, and a gap portion formed by the bent shape connection is closed by the auxiliary lid plate to form a groove. It is characterized by a structure that ensures a lid function.
[0011]
[Action]
In the interconnecting structure of the groove lids of the present invention having the above-described configuration, the auxiliary lid plate on one side is semicircular when the ends of the pair of groove lids are opposed to each other, A pin pin in the longitudinal direction of the groove cover of the second connecting plate on the other side is connected to the connecting pin of the first connecting plate which is superposed on the lower side of the cover plate and is erected at the center of the semicircular circle on the one side. The pair of groove lids can be connected to each other in a relative bending form with an arbitrary angle of, for example, approximately 30 ° or less, without the edge of the auxiliary lid plate interfering with the inside of the counterpart side plate. Thus, it is possible to lay in a straight line in a straight-bendable form.
[0012]
The gap between the cover plates generated between the pair of groove covers is closed by the auxiliary cover plate to ensure the function of the groove cover, and the connection and disengagement are not required for tightening / detaching the connection bolt. -Since it can be done by one-touch interconnection and disengagement of the second connecting plate, it is very easy to lay the connection and remove it during maintenance.
[0013]
Further, the adjacent mutual groove lids are connected and locked in a chained manner by the connecting pins and the pin holes, thereby restricting the mutual connecting gap in the longitudinal direction of the groove lid to prevent the lengthening and normal laying of the groove lids. Maintain a stable posture. There are the above specific effects.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
With reference to FIG. 1 and FIG. 2, the “interconnection structure of the groove lid” of the first embodiment of the present invention will be described. That is, (refer to FIG. 1) a metal groove lid 1 having a reverse U-shaped cross section having a pair of opposed side plates 3 bent downward on both side edges of a long belt-like flat plate lid plate 2 is formed into a groove body U. In this case, the groove lid 1 has the following interconnection structure. In addition, 4 in the figure is a water passage hole drilled in the cover plate 2.
[0015]
More specifically, an auxiliary lid plate 7 is provided at one side end 5 in the longitudinal direction of the standardized mass-produced groove lid 1 and is welded and fixed to the back side of the lid plate 2 and protrudes as a semicircular tongue piece. A first connecting plate 8 is provided which is fixed to the inner side of the lower edge and protrudes in parallel with the auxiliary lid plate 7 as a tapered tongue piece.
[0016]
The first connection plate 8 faces the center of the semicircular circle 11 of the auxiliary lid plate 7 and the back of the auxiliary lid plate 7 and “the second connection plate 9 to be described later is inserted loosely”. A connecting pin 10 having a slit S ”is fixed upright.
[0017]
On the other hand, the other end 6 of the groove lid 1 is provided with an oval connecting pin hole 12 which can be superposed on the first connecting plate 8 and slidably fits the connecting pin 10 slidably. A second connecting plate 9 drilled in the longitudinal direction of 1 is projected and fixed in the shape of a tapered tongue piece, “auxiliary cover plate 7 / first connecting plate 8” on one side end 5 and second on the other side end 6. An interconnection structure of the groove lid 1 is constituted by the connection plate 9. Reference numeral 14 in the figure denotes a spacer projecting from the side plate 3 in order to secure a gap between the side plate 3 and the side wall of the groove lid U when laid in the groove body U.
[0018]
And (refer FIG.1 (B) (C)) When covering and laying in the upper opening part of the groove body U in series chain form, the 1 side end 5 and the other side end 6 of the groove cover 1 which adjoins and become a pair are connected. The connecting pins 10 of the first connecting plate 8 are inserted into the connecting pin holes 12 of the second connecting plate 9 so that the first connecting plate 8 and the second connecting plate 9 are overlapped and connected and locked.
[0019]
Then, when the auxiliary lid plate 7 is superposed on the lower side of the counterpart lid plate 3 and combined, the upper surface of the lid plate 2 of the pair of groove lids 1 forms the same plane and is sequentially interconnected. Thus, the upper opening of the groove body U is covered. In addition, the groove lid 1 is mass-produced and formed in a standard size such as a length = about 1,000 to 500 mm, and is laid in series and continuously in the upper opening of the groove body U. A thing is fixed to the grooved body U by an arbitrary means such as bolt fastening.
[0020]
The tapered shape of the first connecting plate 8 and the second connecting plate 9 is the trapezoidal shape shown in the figure, and interferes with the inner wall of the side plate 3 of the other side of the groove lid 1 when the bent shape of the groove lid 1 described later is provided. The shape is not set.
[0021]
When the connecting pin hole 12 is similarly arranged in a bent form, “a bent form is formed in which the left and right corners of the cover plate 2 of the pair of groove lids 1 are joined. Since the relative posture of the second connecting plate 9 and the second connecting plate 9 changes, the connecting pin 10 is set to an oblong hole that can slide in the connecting pin hole 12 in the longitudinal direction of the groove lid 1 with a slight stroke in accordance with the change in the relative posture. Is done.
[0022]
The groove cover 1 of the above embodiment has the specific action shown in the paragraphs 0011 to 0013, and the groove cover 1 to be paired as shown in FIGS. It is possible to optionally arrange a bent configuration in which the plane 13 intersects with a crossing angle θ in either of the left and right directions within approximately 30 °.
[0023]
Note that the pin center line of the connecting pin 10 and the circular center of the auxiliary lid plate 7 do not necessarily need to be geometrically accurately matched, and may be in a relative relationship that enables the bent form of the pair of groove lids 1. .
[0024]
【The invention's effect】
As described above, the groove cover having the interconnecting structure of the present invention can be flexibly laid on the spot by adapting to the individual bending form of the groove body by the standardized mass production groove cover. The production cost of the groove cover can be reduced by eliminating the need for the special specification groove cover for the body bending portion.
[0025]
And, since the installation of the groove body on the straight part and the bent part is also `` no bolt tightening and tightening '', the one-touch connection set can be removably attached. In addition to reducing the laying operation cost, there are various practical effects for improving the maintenance workability of the groove body and the groove cover and reducing the maintenance cost.
