Description

{A drainage way cover}

The present invention relates to a drainage lid, and more particularly to a drainage lid for supporting a high load capable of supporting a high load.

The drainage lid is installed at the entrance of a drainage hole or a drainage hole formed in the road, and functions as a passage for introducing rainwater and sewage while filtering out foreign matter. It is one of the drainage facilities.

A plurality of longitudinal supports (bearing bars), which are formed in a planar shape, are welded inside a frame having a generally rectangular shape, and a plurality of longitudinal supports And a plurality of cross bars are welded to the direction support rods in the longitudinal direction to form a lattice shape. Such a structure can be confirmed in a document published in "Steel Grating" in Patent Publication No. 10-2004-0078496 (September 10, 2004).

However, in the case of the conventional drainage lid as described above, deformation such as warping or warping may occur due to the load applied when the heavy weight passes. Therefore, there is a problem that there is a possibility of being damaged by a load at any time in an environment where a high load is applied.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a drainage cover for a high load supporting structure capable of enduring high load and maximizing its ability to withstand loads,

The present invention proposes a drainage cover having a structure capable of withstanding the load in the longitudinal direction or the transverse direction so as to maximize the ability to withstand the vertical load and the torsional load as a whole, thereby achieving the above object.

According to the present invention, since the drainage lid is effectively reinforced as a whole, the drainage lid is improved in its ability to withstand the vertical load and the torsional load, so that the drainage lid can be stably used even under a high load.

And a transverse revetment disposed transversely across the pair of longitudinal supports and spaced at regular intervals, the transverse reinforcement being formed in a cross-section of the cross-section with the inlet facing downward, However,

The longitudinal plate is installed upright in the longitudinal direction of the transverse reinforcement bar so that its upper end is brought into contact with the inner ceiling. The transverse plate is disposed below the longitudinal plate in the width direction of the transverse reinforcement bar so as to be in contact with the longitudinal plate, The present invention proposes a drainage cover for a high-load supporting member which is welded to an inner wall surface to reinforce the ability to withstand a vertical load and a torsional load.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings.

2 is a bottom perspective view of a drainage lid according to the present invention, Fig. 3 is a bottom view of the drainage lid according to the present invention, Fig. 4 is a side view of the drainage lid according to the present invention, Fig. Fig.

As shown in FIGS. 1 to 4, a drainage lid 100 to which the present invention is applied has a generally rectangular shape. And is formed of metal, and in particular, it is formed in a rectangular shape when installed in a common drainage passage formed along a road edge.

The drainage lid 100 includes a transverse reinforcement strip 180 transversely traversed between a pair of longitudinal supports 120 and disposed at regular intervals. In this case, the longitudinal support rods 120 have the shape of a board having a predetermined length, and the transverse support rods 140 having a shape similar to that of the longitudinal support rods 120, as well as the transverse reinforcement rods 180, A cross bar 160 may be provided in the transverse direction between the directional reinforcement bars 180 and in the longitudinal direction transverse to the transverse support rods 140. Needless to say, the transverse support 140 and the crossbar 160 do not differ from known configurations and can be replaced with other configurations.

The transverse reinforcement strips 180 are formed in a cross-section 'U' shape with an inlet facing downward. With this configuration in which the bottom of a square cross-section pipe is open, the lateral support 140, which is simply formed in the form of a plank, is reinforced to improve its ability to withstand loads. In addition, the coating solution used for corrosion prevention during the product manufacturing process easily permeates into the inside of the transverse direction reinforcement band 180, and the remaining coating liquid can be easily discharged, thereby improving the convenience of production.

An end plate 182 and a transverse plate 184 are formed in the transverse direction reinforcement strip 180. The end plate 182 is installed so as to be erected in the longitudinal direction of the transverse direction reinforcement band 180 so that the upper end thereof is in contact with the inner ceiling. Can be fixed through welding. The transverse plate 184 is disposed below the vertical plate 182 in a widthwise direction of the transverse reinforcement 180 so as to be in contact with the end plate 182 while both ends of the transverse plate 184 are welded to the inner wall surface of the transverse reinforcement 180.

The vertical plate 182 and the horizontal plate 184 are formed to be in contact with each other in a standing state so as to support the vertical load and the torsional load applied to the transverse direction reinforcement member 180 while complementing each other. In particular, when the vehicle passes, a load in the diagonal direction is applied to the transverse direction reinforcement frame 180, which can effectively withstand such a load. Therefore, the ability of the drainage can 100 to withstand the load as a whole is remarkably improved. In addition, since the load of the coating liquid is maintained while maintaining the ability to be smoothly introduced into the transverse direction reinforcement band 180 and discharged, the convenience of fabrication can be secured. Further, since the end plate 182 and the transverse plate 184 are installed uprightly, both sides of the plate can be welded in the process of welding, so that a sufficient bonding strength can be secured.

Here, the transverse plate 184 may be inclined at an angle with the transverse direction reinforcement bar 180. The lateral plate 184 is inclined so that the ability to withstand a torsional load can be maximized. The angle of inclination can be determined in a range of approximately 20 degrees to 60 degrees with respect to the internal angle of the inner wall of the transverse reinforcement member 180. [ If the angle of inclination is smaller than the lower limit of the above range, the number of the transverse plates 184 is reduced. If the inclination angle is larger than the upper limit, the number of the transverse plates 184 can be increased excessively, Therefore, it is preferable to determine it within the above-mentioned range.

The strength of the drainage lid 100 is formed very strongly through the construction of the transverse direction bar 180 as described above. Therefore, in the environment where a high load is applied, the cover 100 can be realized with the drainage which stably supports the load without being easily damaged by the external force.

Meanwhile, the drainage lid 100 according to the present invention may further include a longitudinal reinforcing bar 124 which forms a 'C' shaped space with an inlet facing downward together with the longitudinal support rods 120. In this configuration, the volute cover 100 is reinforced in the transverse direction by the transverse direction reinforcement strip 180, and further, the structure for reinforcing the strength of both longitudinal edges.

The longitudinal reinforcing bars 124 are bar-shaped in cross-section 'A' shape and welded to the upper surface of the inner surface of the longitudinal support rods 120 (the surfaces of the longitudinal support rods facing each other, A space is formed by the horizontal portion and the vertical portion of the direction support base 120 and the longitudinal reinforcing base 124. [ The vertical support part 120 and the vertical part are formed in the shape of an eleven letter, and the lower end of the vertical support part 120 is seated on the support part 200 (see FIG. 8) formed at the edge of the drainage part to support the load. ), The ability to support the load is increased by at least two-fold.

A reinforcing plate 126 may be installed in the space defined by the longitudinal support rods 120 and the longitudinal reinforcing rods 124. The reinforcing plate 126 is a rectangular metal plate having a predetermined thickness and is provided at a desired interval. The top is in contact with the ceiling of the space while the two sides are fixed by welding in contact with both side walls to improve the ability to withstand the load and torsion.

FIG. 5 is a bottom perspective view of a drainage lid according to another embodiment of the present invention, and FIG. 6 is a bottom view of a drainage lid according to another embodiment of the present invention.

The drainage lid 100 according to the present invention can be constructed in a manner similar to that of the transverse plate 184 described above. As shown in the figure, the transverse plate 184 is formed so as to be perpendicular to the transverse reinforcement strip 180. As a result, the transverse plates 184 are formed at desired intervals, which are formed perpendicularly to the longitudinal plate 182. At this time, the spacing of the transverse plates 184 is adjusted to a necessary degree by structural calculation.

FIG. 7 is an exemplary view showing the structure of a lateral bar according to another embodiment of the present invention. FIG.

The drainage lid 100 according to the present invention may further include a bottom plate 186 that supports the transverse plate 184 in the longitudinal direction of the transverse reinforcement member 180 below the transverse plate 184.

The bottom plate 186 is a bar-shaped plate having a predetermined width and length, and is formed to be narrower than the width of the transverse bar 180 so that the coating liquid easily penetrates into the transverse bar 180 and the remaining coating liquid is easily discharged .

The bottom plate 186 is welded to the side plate 184 in a horizontal state under the side plate 184. The longitudinal lengths of both ends can be formed to a length reaching the longitudinal supports 120 and can be welded to the longitudinal supports 120.

The load supporting capability of the transverse direction reinforcement frame 180 is further improved by such a configuration, and the load supporting ability of the transverse direction reinforcement frame 180 is further improved. As a result, the transverse plate 184, which is installed upright, It will compensate for the disadvantages.

Meanwhile, it is preferable that the bottom plate 186 is not protruded from the bottom surface of the drainage lid 100 by being accommodated in the transverse direction side reinforcement band 180. The lower surface of the bottom plate 186 is positioned coplanar with or slightly upwardly of the lower end of the transverse reinforcement band 180 so that it can be achieved by adjusting the height of the end plate 182 or the side plate 184. [ to be. Even when the bottom plate 186 reaches the length of the longitudinal support 120, the drain canal 100 according to the present invention is installed at the inlet of the drain, The lower end of the longitudinal support frame 120 and the lower end of the transverse reinforcement frame 180 are entirely in contact with each other to support the load.

8 is a cross-sectional view showing a state where a drain canal cover according to the present invention is installed in a drainage passage.

8 shows a structure in which both lateral edges of the drainage lid 100 are supported at the drainage entrance.

As shown in the figure, the drainage lid 100 according to the present invention covers the inlet of the drainage passage. At the drainage passage, a support jaw 200 is formed on both sides of the inlet so that the drainage lid 100 can be seated.

As described above, the longitudinal reinforcing bar 124, which forms a 'U' shaped space with its inlet facing downward together with the lower end of the longitudinal support rods 120 and the longitudinal support rods 120, The lower end of the longitudinal reinforcement strip 124 is formed to be supported at a position inwardly extended by a predetermined distance from the edge of the support jaw 200. [

That is, among the horizontal part and the vertical part constituting the longitudinal direction reinforcement band 124, the lower end of the vertical part is supported at a position inward by a distance that is equal to the distance from the edge of the support jaw 200. This configuration is formed so that the width of the drainage lid 100 is matched with the distance between the wall surfaces of the support jaws 200 formed on both sides of the inlet and the interval between the vertical portions formed on both sides of the drainage lid 100 The distance between the edge of the base 200 and the edge of the base 200 can be increased.

The lower end of the longitudinal support rods 120 and the lower end of the longitudinally extending ribs 124 are always placed on the support jaws 200 through the above-described structure. In addition, the lower end of the reinforcing plate 126 provided in the space defined by the longitudinal support rods 120 and the longitudinal reinforcing rods 124 is also seated on the support rails 200, so that the load can be stably supported as a whole.

As described above, the drainage lid 100 according to the present invention is mounted on the support jaw 200 having both transversely opposite side edges stably installed at the inlet of the drainage channel to support the load. In the longitudinal direction, And the reinforcing plate 126 improve the load supporting ability and in the lateral direction the ability to support the load by the transverse supporting leg 180 is improved. Therefore, the ability to support the high load as a whole is secured, so that the function can be stably performed in an environment in which a high load is applied.
