[0002]
[Prior art]
A grating having a lattice frame composed of a plurality of main bars arranged in parallel at a predetermined interval and a cross bar extending orthogonally to each main bar is well known. By the way, although this grating is high in strength, it becomes a heavy load and is assembled by welding or the like, so that there is a problem that the production becomes troublesome.
[0003]
[Problems to be solved by the invention]
Therefore, lightweight, as easy construction assembly, as disclosed in real-Open No. 1-137387, a large number of synthetic resin pipes juxtaposed synthetic resin grating has been proposed. In this type, a large number of synthetic resin pipes with open ends are juxtaposed, and the pipes are connected by connecting members arranged along the entire length of the pipe, and end caps are fitted at the ends of the pipes. It is something that you wear. By the way, such a configuration requires that the connecting member be fitted in the receiving grooves formed along the longitudinal direction on both side surfaces of the pipe, so that the fitting work is troublesome, and the connecting member becomes large and handled. Has the disadvantage of becoming cumbersome. Furthermore, since the connecting member is disposed between the pipes, there is a problem that the processing becomes troublesome, such as the need to form through holes in the connecting member in order to ensure water permeability between the pipes. It was.
The object of the present invention is to provide a synthetic resin grating that is easy to assemble.
[0004]
[Means for Solving the Problems]
The present invention, in parallel a large number of synthetic resin pipe end is open, and thereby secure the end cap to the open end, be one that is constituted by connecting each end by a connecting member, said end The cap protrudes on the back surface of the base portion substantially matched with the outer peripheral shape of the synthetic resin pipe, projecting two connecting tongue pieces that are in close contact with the opposing inner surface of the opening end of the pipe, and between the connecting tongue piece pairs, A connecting projection is formed at the center of the base, and the connecting member is separate from the end cap, and a plurality of insertion holes into which the connecting projection is rotatably inserted are formed at both ends. It is formed in a crank shape in cross section, is disposed between the open ends of adjacent pipes, and is arranged so that either insertion hole coincides with each other at the open end position, and the insertion hole is overlapped with each other. Ream formed on end cap Projections so as to penetrate the a synthetic resin grating, wherein each synthetic resin pipe is made is connected.
[0005]
In such a configuration, the connecting member is connected to an end cap that covers the open end of the pipe, whereby the pipes are easily connected. As described above, the connecting member is disposed in a penetrating manner at both ends of each pipe, so that it is small and easy to handle.
[0006]
Here, a plurality of the insertion holes can be formed at each end. Thereby, if the insertion hole is appropriately selected, the interval between the pipes can be easily adjusted, and the same connecting member can be applied even when the width of the pipe is different or when the specification is changed. Furthermore, the selection allows the pipes to be arranged along the bending direction by narrowing the interval between the pipe ends on one side and widening the other side. Various aspects can be easily set, such as making it possible to easily cope with curved grooves, or changing the interval between pipes as appropriate.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
Embodiments of the present invention will be described with reference to the accompanying drawings.
Here, the grating 1 according to the present invention is configured by arranging a large number of synthetic resin pipes 2 having a cross-sectionally R-shaped parallel structure and connecting the ends thereof by a connecting member 20 as shown in FIGS . Is.
[0008]
This configuration will be described in further detail.
The synthetic resin pipe 2 is formed by extrusion molding with a hard vinyl chloride resin, and, as shown in FIG. 6, a covering piece 3 formed with a soft vinyl chloride resin having a hardness of 70 degrees is joined to the upper surface thereof. . This covering piece 3 is provided with an anti-slip surface 4 whose upper surface is a continuous chevron-like tooth-like surface, thereby improving the sliding resistance and producing an anti-slip effect. The synthetic resin pipe 2 is manufactured according to specifications in various other shapes such as a shape having a height of 25 mm, a width of 16 mm, and a length of 200 mm.
[0009]
An end cap 10 is fitted into the open end 5 at the end of the synthetic resin pipe 2. As shown in FIGS. 7 to 10, the end cap 10 is respectively formed on the back surface of the rectangular base portion 11 substantially matched with the outer peripheral shape of the synthetic resin pipe 2 and on the inner surface of the pipe 2 facing the open end 5. The connecting tongue pieces 12 and 12 are in close contact with each other, and a connecting projection 13 is formed between the connecting tongue pieces 12 and 12 at the center of the base 11. The connecting protrusion 13 has a truncated cone shape at its end so that it can be easily inserted into insertion holes 24a and 24b described later. Further, a continuous chevron-like tooth-like surface 14 is formed on the upper surface of the base 11 of the end cap 10 so as to produce an anti-slip effect, similar to the anti-slip surface 4 of the synthetic resin pipe 2.
[0010]
Next, the configuration of the connecting member 20 will be described.
As shown in FIGS. 11 and 12, the connecting member 20 has a cross-sectional crank shape in which the connecting end portions 21, 21 are stepped through the partition portion 22, and each step is connected to the connecting end portions 21, 21. When the connecting end portions 21 and 21 of the adjacent connecting members 20 and 20 are overlapped with the stepped portion, a uniform shape is obtained. In addition, each connecting end portion 21 is formed with a hole portion 23 in which insertion holes 24a and 24b having different center positions in the lateral direction are continuous. Further, a positioning notch 25 is formed at the corner edge of each connecting end 21. A positioning protrusion 26 that fits into the positioning notch 25 is formed at a portion that coincides with the positioning notch 25 of the partition part 22 in the lateral direction.
[0011]
With this configuration, the assembly means of the grating 1 will be described.
First, as described above, a plurality of connecting members 20 are overlapped with each other at the connecting end portions 21 of adjacent connecting members 20, and as shown in FIG. 3 or FIG. , Or all are made to coincide with each other in each figure.
[0012]
Here, FIG. 3 shows that the outer insertion holes 24a and 24a are matched, and in this case, the maximum interval L1 of the synthetic resin pipe 2 is realized.
[0013]
In FIG. 13A, the hole 23 is completely matched, and the insertion holes 24a and 24b are matched on the front and back. At this time, the pair of right and left insertion holes 24a and 24b may be selected. In this case, the intermediate interval L2 of the synthetic resin pipe 2 is realized.
[0014]
Furthermore, FIG. 13B shows the case where the inner insertion holes 24b and 24b are made to coincide with each other. In this case, the minimum interval L3 between the synthetic resin pipes 2 (end caps 10) is set. In this case, the positioning protrusions 26 are fitted into the positioning notches 25 to prevent vertical displacement between the synthetic resin pipes 2 and the synthetic resin pipes 2 are in close contact with each other without a gap. It becomes. This is effective when it is necessary to completely cover the groove.
[0015]
In this way, by selecting the overlapping mode of the holes 23, it is possible to adjust the parallel arrangement interval of the synthetic resin pipes 2 to any one of the intervals L1 to L3.
[0016]
FIGS. 14A and 14B show a configuration example in which the interval between the synthetic resin pipes 2 is changed. In this way, it is possible to set not only equal intervals but also a variety of different intervals, such as adjusting the groove intervals to the surrounding design or creating a unique hobby. It will be possible to cope with.
[0017]
Thus, the connection projection 13 was selected as described above by setting the end cap 10 so that the connection tongue pieces 12 and 12 straddle the end cap 10 in the longitudinal direction of the connection member 20. It fits into one of the insertion holes 24a, 24b.
[0018]
Then, the connecting tongue pieces 12 and 12 of the end caps 10 are press-fitted into the open ends 5 of a plurality of synthetic resin pipes 2 juxtaposed in advance. As a result, the connecting tongues 12 and 12 are pressed against the inner surfaces of the opening ends 5 of the synthetic resin pipe 2 facing each other, and the end caps 10 are fitted, and each synthetic resin pipe 2 is passed to each end. Each of the connected members 20 is connected.
[0019]
As shown in FIGS. 1 and 2, the grating 1 configured as described above is supported by receiving frames 30 and 30 provided on both sides of the groove and is attached to the groove.
[ 0020 ]
In such a configuration, as shown in FIG. 15, it is easy to line up the synthetic resin pipes 2 in the bending direction. That is, on one side, the interval L3 is selected and the connecting protrusion 13 is inserted, thereby narrowing the position interval between the ends of each synthetic resin pipe 2, and on the other side, the interval L1 is selected. Then, the position interval between the end portions of each synthetic resin pipe 2 is increased. Thus, the synthetic resin pipes 2 are arranged in a line along the bending direction, and can be applied to curved grooves and arcuate corners of the grooves.
[0021]
At this time, since the insertion holes 24a and 24b are continuously formed, the connecting protrusion 13 inserted into one of the insertion holes is forcibly passed through the narrow width portion between the insertion holes 24a and 24b using elastic deformation. Thus, the interval can be changed while maintaining the insertion state. Therefore, the synthetic resin pipes arranged in a straight line direction can be changed in the bending direction by pulling or pushing the adjacent connecting members 20 and 20 to each other, so that it corresponds to the groove shape at the construction site. Thus, the grating 1 can be easily shaped.
[0022]
As described above, a plurality of insertion holes 24a and 24b are formed in the connecting end portions 21 and 21, so that the intervals between the synthetic resin pipes 2 can be made or the widths of the synthetic resin pipes 2 are different. In addition to being connectable, there are advantages that the synthetic resin pipes 2 can be juxtaposed in the bending direction.
[0023]
On the other hand, as shown in FIG. 16, in the configuration of the present invention, the relative inclination of the connecting members 20 can be made possible. In this case, the end cap 10 adjacent in the left side in the drawing relative to the center of the end cap 10 in FIG. (Synthetic resin pipe) can achieve a maximum inclination angle theta. Here, since the end cap 10 adjacent on the right side in the figure can also be tilted at the maximum tilt angle θ, as a whole, a refraction angle of 2θ can be realized with the center end cap 10 as the center. For this reason, even when the groove is inclined downward from the middle, the groove is formed by forming an elbow-shaped bend around the specific synthetic resin pipe 2 corresponding to the refracting portion. The grating 1 can be deposited evenly on the road.
[0024]
Further, the synthetic resin pipe 2 because it is rotatable relative to the connecting member 20, as possible out changing the height of each synthetic resin pipe 2 while horizontally holding the slip plane 4. Thus, causing a step in the top surface cross each synthetic resin pipe 2 also becomes possible, while maintaining the slip effect slip surface 4, for example in a groove path having the gradient held horizontally, synthetic resin pipe 2 can be deposited uniformly.
[0025]
【The invention's effect】
In the present invention, as described above, a large number of synthetic resin pipes 2 having open ends are arranged in parallel, and the end cap 10 is fixed to the open end 5, and insertion holes 24 a and 24 b are respectively formed in the connecting end 21. Using the connecting member 20 having a crank shape in cross section, the connecting end portions 21 and 21 of the adjacent connecting members 20 and 20 are overlapped with each other, and thereby the end cap 10 is inserted into the pair of insertion holes 24a and 24b that are coincident with each other. Since the pipes 2 are connected to each other so as to penetrate the connecting projections 13 formed in the above, only by attaching the end cap 10 and the connecting member 20 to the opening end 5 of each synthetic resin pipe 2, Each synthetic resin pipe 2 can be assembled, and it is easy to assemble, and the connecting member 20 becomes small, and handling is easy. In addition, the connecting members 20 and 20 can be greatly inclined, the synthetic resin pipes 2 can be displaced relatively in the height direction, and can be applied to a groove having a drop. Furthermore, since the synthetic resin pipe 2 can be rotated with respect to the connecting member 20, it is possible to horizontally hold the anti-slip surface formed on the upper surface of the synthetic resin pipe 2 in the groove with a drop. It becomes.
[0026]
Further, a plurality of the insertion holes 24 a and 24 b can be formed in each connection end portion 21. Accordingly, if the insertion holes 24a and 24b are appropriately selected, the same connecting member 20 can be applied to the change in the specification of the interval between the pipes. By narrowing the interval between the end portions of the pipes 2 and widening the other side portions, the pipes 2 can be arranged in a line along the bending direction. It can be easily handled.
