Abstract

The present invention relates to a permeable load distributing grating and, more specifically, to a permeable load distributing grating. First load distributing members, which have a plurality of drain holes provided in the upper surface thereof to distribute the load, and enable odor rising from a drain to flow in whirls, thereby blocking the odor from rising, are continuously installed. In this state, second load distributing members for distributing the load are installed on the upper surfaces of the first load distributing members. A water permeable filler is stacked on the upper surfaces of the first load distributing members. Therefore, the permeable load distributing grating can distribute the load, thereby preventing deformation or damage caused by the load. In addition, since the first and second load distributing members stably fix the water permeable filler, the permeable load distributing grating can prevent sinking, dropping, and cracking of the water permeable filler when shock and vibration occurs, and can reduce the usage amount of the water permeable filler, thereby relatively reducing the weight.

Description

PERMEABLE LOAD BALANCING GRATING}

The present invention relates to a water permeable load distribution grating, and more particularly, a first load dispersing member for distributing a load while having a plurality of drain holes on the upper surface, and vortexing the odor rising from the drain to block the rise of the first load distribution member continuously In one state, a second load dispersing member for distributing the load is installed on the upper surface of the first load distributing member, and then a water permeable filler is laminated on the upper surface of the first load dispersing member to distribute the load so that deformation or damage occurs due to the load. In addition, in the present invention, the first and second load dispersing members stably fix the water-permeable filler, so that subsidence, drop-off and cracking of the water-permeable filler occurs when shock and vibration occur, and water permeability It relates to a water-permeable load-distributing grating that allows the weight to be relatively low by reducing the amount of cast filler used.

In general, in order to prevent rainwater from overflowing, a drain hole formed as a long passage is formed on the roadside to prevent rainwater from overflowing, and a steel grating is installed on the upper part of the drain hole for safety.

Such a steel grating is usually formed in a grid shape in which a plurality of bearing bars and cross bars intersect within a square-shaped main frame. Here, the bearing bar is a part supporting most of the load applied to the steel grating, and is horizontally disposed at the same interval, and a plurality of cross bars are disposed orthogonally to the bearing bar at the same interval.

However, the steel grating of the above structure may lose the drainage function due to the inflow of various foreign substances, including fallen leaves or cigarette butts, through the space inside the frame, thereby clogging the drain hole, and impairing the living environment due to the smell of the drain hole rising, impairing the living environment, and car key. There is a problem that it is difficult to take out important items such as the one that is missing.

In order to solve this problem, Korean Patent Registration Nos. 10-1264097 (Steel grating with foreign substance inflow prevention function and odor blocking function and manufacturing method thereof), No. 10-2035447 (Drainage grating using water permeable mixture), No. No. 10-2201427 (integrated grating for preventing inflow of dirt and blocking odor) and the like are disclosed.

The steel grating having the function of preventing the inflow of foreign substances and blocking the odor and the manufacturing method thereof can prevent foreign substances from entering at all by filling the inner space of the steel grating with a soil composition, and block the odor coming up from the drain, and the water permeability It is excellent to provide a steel grating having a function of preventing the inflow of foreign substances, which allows rainwater to pass through the soil composition smoothly and has excellent strength to support the load of a vehicle, and a method for manufacturing the same.

The drain grating using the water-permeable mixture includes a water-permeable mixture in which aggregate and a polyurethane solution are mixed and stirred, a square frame in which the water-permeable mixture is cured, and a water-permeable mixture cured in the square frame at the bottom of the drain. It may include a support to prevent deviation in the direction.

The integral grating for preventing the inflow of filth and blocking odors is an outer frame including a frame to be seated on the upper part of the rain hole, is formed to have a predetermined interval inside the outer frame, and is arranged side by side along the longitudinal direction of the outer frame a plurality of I-bars formed through the I-bar to cross the I-bar, a crossbar extending along the longitudinal direction of the outer frame, and formed in a space between the predetermined I-bars among the plurality of I-bars, A V-bar continuously arranged in a zigzag form in a direction perpendicular to the longitudinal direction of the outer frame, a lower support plate formed under the outer frame and arranged repeatedly in a lattice shape to have a plurality of transmission spaces, the lower support plate and the An inner mesh disposed in the space between the plurality of I bars and having a hole smaller than the permeation space of the lower support plate, and filling in the space between the I bars, but not filling in the space between the V bars It is characterized in that it contains a material.

However, since these conventional water-permeable gratings do not have a structure supporting the water-permeable filler or form a wire mesh or bar shape, subsidence, drop-off and cracking of the water-permeable filler occurs when shock and vibration occur, and the water-permeable filler is installed as much as the height of the grating. Due to the charging, there is a problem in that the amount of the filler is relatively increased and thus the weight is increased.

In addition, since the load is concentrated on the bearing bar and the water-permeable filler in the conventional water-permeable grating, deformation or damage occurs due to the load, and there is a problem in that the odor passes through the water-permeable filler as it is and rises.
