Description

Manhole cover assembly for footpath using terrazzo tile

The present invention relates to a manhole cover assembly for sidewalks using terrazzo tiles, and more specifically, anchor bolts and glass fiber layers fastened to the terrazzo tiles are provided to enhance the adhesive force of the terrazzo tiles, and The present invention relates to a sidewalk manhole cover assembly using a terrazzo tile to prevent contamination of the jaw tile and to prevent condensation and cracking.

In general, the manhole is a hole that allows people to enter and exit the basement. The place where it is installed is installed in the middle of the pipe, where the direction changes, the starting point or intersection, and the long straight part. It is used for contact.

In the case of the manhole connected to the ground such as the sidewalk in the manhole as described above, a manhole cover assembly is installed at its upper end so as to be parallel to the sidewalk flattened by the sidewalk block.

Here, the manhole cover assembly is typically composed of a manhole cover and a manhole cover frame, the manhole cover frame is installed on the upper part of the manhole and then assembled so that the manhole cover is removable in the center of the manhole cover frame.

In this way, the manhole cover is removably assembled so that water and sewage, electricity, communication line maintenance and other management can be made.

On the other hand, in the conventional manhole cover assembly to manufacture a manhole cover and a manhole cover frame, first mix the pig iron and cast iron to cast each frame.

Then, after filling the concrete using the cement and gravel in the frame, respectively, after attaching the artificial stone using granite and the like and color pigments, the surface of the artificial stone attached to the curing was prepared by manufacturing.

However, the conventional manhole cover assembly as described above has a problem of causing environmental pollution due to the sludge generated during the grinding process of artificial stone.

As such, the sludge generated during the process of changing the artificial stone causes environmental pollution, and thus, the operation of changing the water in the manufacturing plant and the construction site where the environmental purification facilities are not equipped according to the government regulation is not possible.

As a result, it is impossible to grind water at the manufacturing and construction sites of artificial stone, so that it is impossible to have an environmental purification facility requiring large capital, and production at a small manufacturing factory has been stopped.

Meanwhile, in recent years, various sidewalk blocks have been developed and constructed on the sidewalk, but the conventional sidewalk manhole cover is not harmonized with the sidewalk block because the improvement of the material and design of the product is not made smoothly. There was a problem that did not meet the aesthetics.

Moreover, the conventional manhole cover assembly for the sidewalk is weak due to the leakage between the various blocks (artificial stone) attached to the top of the filled concrete and the cured concrete layer, the adhesion of the block is weak, the occurrence of cracks in the block and concrete layer, etc. There was a problem that the same product quality is degraded.

In order to solve the above problems, the present invention relates to a manhole cover assembly for a sidewalk using a terrazzo tile, and more particularly, by providing an anchor bolt and a glass fiber layer fastened to the terrazzo tile, It is an object of the present invention to provide a manhole cover assembly using a terrazzo tile to enhance adhesion, prevent contamination of the terrazzo tile due to leakage, and prevent condensation and cracking.

In order to achieve the above object, the sidewalk manhole using a terrazzo tile according to a preferred embodiment of the present invention is a lid frame filled with a filling inside the frame; A lid frame skeleton having a seating frame to which the lid frame is inserted and corresponding to the lid frame; A terrazzo tile disposed on an inner upper portion of the lid frame and the frame frame frame and finished with surface polishing; And it comprises a glass fiber layer in close contact with the lower surface of the terrazzo tile.

Here, the lid frame is preferably made of an outer frame for receiving the filler and terrazzo tile on the inside, and an auxiliary frame formed of a grid type on the inner lower portion of the outer frame.

At this time, the outer frame of the lid frame is provided with a stepped portion toward the center to facilitate the seat frame frame, the seating frame of the lid frame frame may be formed with a seating portion corresponding to the stepped portion of the lid frame.

In addition, the predetermined position of the auxiliary frame is provided with a first fixing plate formed with a fixing hole so that the terrazzo tile can be guided and fixed smoothly, one side of the lower portion of the terrazzo tile fixing hole of the first fixing plate It is preferable that the other side of the anchor bolt to be fixed to the fastening fastening.

Further, the terrazzo tile provided inside the lid frame may be divided into a plurality of pieces to facilitate the manufacturing operation, and the first fixing plate and the anchor bolt may be provided to correspond to the plurality of terrazzo tiles.

On the other hand, the lid frame frame comprises a seating frame, an outer frame surrounding the seating frame, and a connecting frame for interconnecting the seating frame and the outer frame.

Here, the connecting frame is formed in plural along the circumferential direction of the seating frame, the predetermined position of the connecting frame is provided with a second fixing plate formed with a fixing hole so that the terrazzo tile can be guided and fixed smoothly, It is preferable that the other side of the anchor bolt that is fixed to the lower side of the terrazzo tile is inserted into the fixing hole of the second fixing plate.

Further, the terrazzo tile provided inside the frame frame frame is divided into a plurality of pieces to facilitate the manufacturing operation of the lid frame, the second fixing plate and the anchor bolt corresponding to the plurality of terrazzo tiles to be provided Can be.

Referring to the effect of the sidewalk manhole cover assembly using a terrazzo tile according to the present invention described above are as follows.

First, it is possible to maintain a solid binding force with the mortar and concrete layer by strengthening the adhesive force of the terrazzo tiles by being provided with anchor bolts fastened to the terrazzo tiles.

Second, by interposing a glass fiber layer between the terrazzo tile and the mortar layer, it is possible to prevent the contamination of the terrazzo tile due to leakage and to prevent cracks due to leakage and condensation.

Third, by applying the terrazzo tiles of the sidewalk block type divided into a plurality, the manhole cover assembly can be matched with the urban aesthetics of the construction site by naturally blending with the sidewalk on which the sidewalk block is laid.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.
