Description

Roadside Tree Cover {Tree grates}

The present invention relates to a structure of a protective cover installed to protect the roadside trees planted on the sidewalk, and more specifically, not only roads, but also sidewalks such as plazas, business areas, industrial complexes, parks, public facilities, walkways, residential areas, etc. The present invention relates to a roadside protective cover of a novel geometrical structure installed to protect a tree planted in a region.

The roadside shroud has been manufactured and used not only to directly protect trees from pedestrians on the sidewalks but also to help the city's beautification.

However, the roadside protective cover is installed around the bottom of the trunk (Trunk) of planted trees until now, mainly for the purpose of preventing damage caused by weight or other external impact or load of pedestrians, the material is stone or cast iron Emphasis has been placed on assembling and constructing parts for the purpose of improving the convenience of installation and construction by forming a heavy body.

In addition, there are no legal and technical standards on the functionality, safety and durability of roadside protective covers in public facilities. Where there is a risk, cover should be installed, but the surface of cover should be the same height as sidewalk, and if the cover has lattice holes or gaps, the gap should be 1 centimeter or less. " "The cover shall be installed where there is a risk that the person with a disability, etc. may fall out, and the surface shall be flush with the access route, and the gap shall be provided if the cover has a grid hole or gap. Should be less than 2 centimeters. " Even in some cases not even related KS standards to support them.

As such, the basic foundation of the law and industrial standards is weak, and domestic roadside protective cover products are manufactured, sold, and constructed without any standard.

As a result, there is no universal design for pedestrians, and the use of raw materials is reduced to reduce production costs. Cast iron products with very wide slit, made of iron plate (rolled steel plate SS400), which is the most slippery material that is easy to induce pedestrian accidents when the road surface is wet due to rain or when the road surface is frozen in winter. In order to further reduce the unit cost, the product is made of SS400 thin (3.2mm thick) SS400, and if it runs on it, it does not withstand light loads such as human weight and deforms.

In addition, the roadside protective cover of the conventional structure has a flat surface of the cover as shown in Figure 1 because the coefficient of friction is low, the fall of the pedestrian slips due to the snow during the thaw after the winter season excellent or winter freezing. In addition, the width of the cover slit is not considered at all for pedestrians or wheel canes of traffic, so the heels of the high heels fall into the slit while walking, or the end of the old man's cane is caught in the slit. In addition, even the small wheels of strollers and wheelchairs have been caught in the slit of the cover, which has been a barrier to the smooth movement of the means of transport used by guardians and the disabled.

For these and other reasons, the pedestrians, elders, guardians, and handicapped people who pass through the roadside protective cover installed in plaza business and commercial areas, industrial complexes, parks, public facilities, walkways, apartment complexes, residential areas, roadsides, etc. It is undeniable that roadside shrouds were dangerous areas for safety accidents.

In order to prevent the safety accident as described above and prevent it in advance, the present inventors have developed a method of forming and manufacturing a cover for the first time in this field by forming a non-slip irregularities on the surface of the roadside protective cover, in particular for the purpose of preventing slipping. It has been made public.

As shown in Table 1 to Table 4, the test results of Examples 1 to 4 showed that the rolled steel (SS400) of Sample 1 with slits had higher resistance than cast iron (GCD500) of Sample 2 with slits. Laser cutting is performed in the manufacturing process of the rolled steel (SS400) material, so the cutting surface is very sharp, which is the most slippery in the sample group without the slit, but in the case of the slit, the resistance is higher than that of the cast iron (GCD500) surface. This is because, due to the nature of the manufacturing process, there can be no rolled steel SS400 that is not slippery than cast iron GCD500.

In addition, cast iron (GCD500) of Sample 2, which did not have a non-slip surface structure, showed a significant difference in the slip resistance value (BPN) according to the presence or absence of a slit, and cast iron (H30) of Sample 3 having a non-slip surface structure. GCD500 measured a constant high slip resistance (BPN), regardless of the direction of the slit.

Therefore, it was confirmed that it is preferable to employ the cast iron (H30; GCD500) of Sample 3 having a non-slip surface structure in the roadside protective cover of the present invention.
