KR101432673B1 - Grating high rigidity for load - Google Patents

Abstract

The present invention relates to a high-rigidity grating for a heavy load which minimizes seeing of the inside of a drain and the input of foreign matters, and evenly disperses the heavy load applied to an upper portion to a wide area, and which further increases the rigidity for a drainage space to prevent the deformation or damage and stably maintains an installation state. The grating includes load reinforcing members having an anti-skid recess protruding from the surface which is alternatively installed between rectangular flange frames to disperse the heavy load applied from the upper side and thus prevent the deformation, wherein a drainage space and a wide area such as a C-shaped steel are positioned on the upper portion; a division bearing bar provided in the vertical direction in the drainage space; and lateral reinforcing members having the width corresponding to the drainage space which are installed in the flange frames on both sides of the division bearing bars. Assembling grooves are formed at regular intervals on the wise upper surface of the division bearing bar, and a reinforcing division connecting bar is provided with an assembling portion coupled to the assembling groove so that the assembling portion has the same height as that of the load reinforcing member, the division bearing bar and the flange frame. A V-shaped vent portion is formed between the assembling portions, so that the reinforcing division connecting bar is connected in a W-shape.

Description

{Grating high rigidity for load}

More particularly, the present invention relates to a high rigidity grating for heavy loads, and more particularly, to a structure for minimizing the appearance of the inside of a drainage channel and minimizing the introduction of foreign matter, and evenly distributing a large area over a heavy load applied to the upper portion, The present invention relates to a high-rigidity grating for heavy loads which can be stably maintained without being deformed or damaged.

Generally, a drainage lid is installed on a drainage port formed on a road or on the upper surface of a drainage line to filter out foreign matter and guide rainwater and wastewater to be smoothly drained to a river through a drainage line and a drainage treatment plant through a drainage line. It is one.

In this way, a conventionally used drainage lid is installed in a drain or a drain in a continuous manner, and a well-known construction is that a plurality of bearing bars in the form of a flat plate in the width direction are welded between the side frames on both sides, A plurality of cross bars, which are screw-shaped in the longitudinal direction, are welded to the upper end of the bearing bar to form a lattice shape.

However, in the case of the conventional drainage lid, there is a problem that deformation such as warping or bending is caused by a load applied when a heavy weight passes through, and after the deformation, a lot of inconvenience due to passage has occurred Deformation more severely occurred with the applied load.

In addition, the conventional drainage lid has a problem in that the inside of the drainage channel must be exposed so that the dirty environment inside the drainage water is exposed to the outside, thereby detracting the aesthetics around the drainage line.

In order to solve such a problem, Patent Publication No. 10-0779563 entitled " Heavy Drainage Drain Lid "has been proposed, which is able to have greater responsiveness to the load applied from the upper portion. In the heavy load drainage lid, And a reinforcing plate 130 having a length shorter than the length of the supporting member is formed on the bottom surface of the supporting member, The load applied to the reinforcing plate is dispersed through the support member and is less deformed than the conventional drainage cover.

Another prior art heavy-duty drainage lid as in the "Heavy-Duty Drainage Lid" of Patent Registration No. 10-0734037 is a square-shaped rectangular steel having a high correspondence to the load applied from the upper side between the side frames on both sides And a plurality of vertical flat plates are formed between the rectangular steel bars and both side ends thereof, and the fixing plate is fixed to the vertical flat plate so as to penetrate through the middle plate.

However, even in the case of the above conventional heavy-duty drainage lid, if a heavy load applied to the upper part is frequently applied, the load is not able to withstand the load applied thereto, and the deformation occurs within a short period of time.

In other words, as the heavy load applied from the upper portion is transmitted to the supporting member and the rectangular steel which are spaced apart at regular intervals, the heavy load is not uniformly dispersed throughout the cover by the drainage but the concentrated load is applied to the portion where the supporting member or the rectangular steel is formed , And deformed within a short period of time.

In order to prevent such drawbacks, the present invention has been disclosed in Korean Patent No. 1051683 (registered on July 19, 2011), which has a width that can be raised on a support frame of a drainage channel, A plurality of vertical plates fixed to the bottom surface of the upper plate member in the width direction so as to have a high supporting force with respect to a load transmitted from the upper plate member, A lower plate member having a plurality of drain holes vertically penetrating the bottom surface of the vertical plate and fixed in the form of a plate having an area corresponding to the upper plate member so as to have a high counterforce against a load transmitted from the vertical plate; And side members fixed to both ends of the member.

However, such a conventional technique has a drawback that the drainage can not be normally secured through the number of the inflow holes formed in the top plate member, and the inside of the drainage passage becomes difficult to see.
