DETAILED DESCRIPTION OF THE INVENTION
1 to 6 relate to an embodiment of a side groove cover with embedded insert grating according to the present invention, and FIG. 1 is a plan view of a side groove cover with embedded insert grating according to an embodiment of the present invention. 2 is an AA enlarged cross-sectional view of FIG. 1, FIG. 3 is a plan view of insert grating, FIG. 4 is a side view of insert grating, FIG. 5 is a cross-sectional view of FIG. An explanatory view is shown.
[0008]
In the figure, reference numeral 1 denotes a side groove cover body in which insert grating is embedded. The cover body 1 is formed of concrete into, for example, a substantially V shape in a side view, and an upper surface of a side groove 2 such as a U shape as indicated by a virtual line. It is supposed to be placed on.
[0009]
The upper surface of the lid body 1 is an inclined surface that descends from both sides in the longitudinal direction of the lid body 1 toward the center side, and is parallel to the longitudinal direction of the lid body 1 near the lower portion of the inclined surface. Then, the insert grating 3 is embedded in the upper surface portion of the lid 1, and a hole 4 is formed below the embedded insert grating 3. Further, notches 5 and 5 that are fitted to the side grooves 2 are formed at the bottoms of both ends of the lid 1.
[0010]
The insert grating 3 includes a grating main body 6 and a holding frame 7 that holds the peripheral side surface and the bottom surface thereof. The grating main body 6 is three-dimensionally formed in a substantially rectangular shape with a U-shaped lower surface in a sectional view, and a plurality of rainwater circulation holes 8, 8,... Are formed on the upper surface, and the rainwater circulation holes 8, 8,. Are formed up to the upper part of the bottom surface 10 of the holding frame 7. Further, a plurality of protrusions 11, 11,... Are formed on the peripheral side surface of the grating body 6, and the grating body 6 is formed of a synthetic resin such as reinforced plastic.
[0011]
The retaining frame 7 has a plurality of recessed holes 12, 12,... That engage with the projections 11, 11,... Of the grating body 6 on the inner peripheral surface thereof, and protrudes outward from both lower ends of the retaining frame 7. Reinforcing plates 13, 13,... Are formed, and the holding frame 7 is also formed of a synthetic resin such as reinforced plastic.
[0012]
In the side groove cover body 1 in which the insert grating having the above structure is embedded, first, the projections 11, 11,... Of the grating body 6 are engaged with the concave holes 12, 12 of the holding frame 7, and the grating body 6 The peripheral side surface and the bottom surface are held by the holding frame 7, and the grating main body 6 is firmly locked and held by the holding frame 7, whereby the insert grating 3 can be assembled.
[0013]
In this embodiment, two insert gratings 3 are embedded. When the lid body 1 is formed, an appropriate number of the insert gratings 3 is determined according to the length of the lid body 1 in the lateral direction. It is possible to install one or a plurality of the insert gratings 3 in the mold for molding. And when pouring concrete into the mold, a core 4 can be installed on the inner periphery of the insert grating 3 to form the holes 4 in the lid body 1. At this time, the rainwater circulation holes 8, 8, The boundary plates 9, 9, ... are formed up to the upper portion of the bottom surface 10 of the holding frame 7, so that it is not necessary to provide the core for each rainwater circulation hole 8 and insert with one core. Large holes 4 can be formed in the entire grating 3, and the lid 1 can be easily and easily manufactured.
[0014]
Further, since the reinforcing plates 13, 13,... Projecting outward from both lower ends of the holding frame 7 are formed, the holding frame 7 is provided on the upper surface portion of the concrete lid 1 with the reinforcing plates 13, 13,. ... is sandwiched with concrete from above and below, and is securely embedded, preventing the insert grating 3 from coming off, and the insert grating 3 being molded from a synthetic resin, so that it does not rot and can withstand long-term use. It becomes.
[0015]
For example, when the lid body 1 is placed on the upper surface of the side groove 2 installed in parallel with the roadway or the like at the boundary between the roadway and the sidewalk, the notches 5 and 5 formed at the bottoms of both ends of the lid 1 are formed in the side groove 2. The lid body 1 can be easily placed in the side groove 2 simply by fitting with the upper part of the lid.
[0016]
In addition, for example, during heavy rain, rainwater is discharged into the side groove 2 through the rainwater circulation holes 8, 8,... Of the grating body 6, and it is difficult for water to collect on the roadway and the like, so that traffic such as cars passing through the roadway is less hindered. In addition, when the holes 8 are clogged with dust, pebbles, etc., the grating body 6 can be removed from the holding frame 7 and easily cleaned, and the rainwater circulation holes 8, 8,. The grating body 6 can be easily replaced even when it is stuck.
[0017]
It is possible to change the shape of the rainwater circulation holes 8, 8,...
[0018]
【The invention's effect】
In the side groove lid body in which the insert grating according to the present invention is embedded, the grating main body which is the rainwater circulation pore portion is securely held by the holding frame, and the grating main body is held by the concave and convex engagement with the holding frame. , By removing only the grating body, clogging of dirt, pebbles, etc. can be cleaned particularly easily, and even if the rainwater circulation pore part is broken, the grating body can be replaced, and the lid body is easy and easy to manufacture. The insert grating is securely embedded in the lid body, and the side groove lid body is embedded with the insert grating having excellent rainwater drainage capability.
