It is about a sidewalk block for a building complex.

In general, turf is a perennial herbaceous plant of the crested family with strong regenerative properties, with stems sticking to the ground, extending sideways, and rooting at each node, withstanding low mowing and tread pressure among ground cover plants covering the ground surface. has been developed

Turf has excellent effects such as preventing soil pollution, preventing soil erosion, improving water holding capacity, creating a pleasant green environment, preventing injuries during sports games, purifying the air, and mitigating noise. For example, in the process of road construction or landscaping, cutting or embankment occurs, and it is common to create grass and trees to prevent erosion and loss due to flooding such as rainwater and floods in such cutting or embankment and embankment. am.

Grass constructed for landscaping provides a sense of emotional stability to those who visit it, and provides a place for family vacationers to enjoy, but if it is opened indiscriminately, the leaves of the grass are crushed, resulting in incomplete growth or, in severe cases, Injuries to the hair roots often caused the grass to dry out.

Accordingly, the development of a sidewalk block that allows pedestrians to walk in a place where the grass is created as well as protection management of the lawn is being actively performed.

In addition, technology related to facilities for simultaneously protecting lawns and allowing pedestrians to pass has been disclosed through Patent Registration Publication No. 10-0651827 (hereinafter referred to as 'prior literature').

Referring to the above drawings, a sidewalk block for a building complex (hereinafter referred to as a 'sidewalk block') 100 capable of protecting a lawn according to the present invention includes a sidewalk block main body 200 and an upper cover 300 for lawn protection. can include

The sidewalk block body 200 for protecting the lawn may include a perforated base plate 210, a leg 220, a mesh plate 230, and a connecting rod 240.

The perforated base plate 210 may have a rectangular shape, and a plurality of square holes 211 are formed in its inner region. The square hole serves as a growth space through which grass on the ground can grow upward.

The leg 220 is composed of a plurality, may be integrally formed throughout the lower surface of the base perforated plate 210, and the formation position may be formed in a region avoiding the square hole 211. Accordingly, the height of the base perforated plate 210 can be increased to correspond to the height of the grass, and since the formed position does not overlap with the square hole 211, it is possible to prevent the hole diameter of the square hole from decreasing.

The net plate 230 is composed of four, disposed on all sides of the perforated base plate 210, and installed to be seated on the grass floor, and may be composed of a square frame 231 and a wire 232. Here, the net plate 230 can enlarge the grounding area and minimize damage to the lawn by the net.

One side of the square frame 231 is integrally connected to one end of the connecting rod 240, and wire holes 231a may be formed at regular intervals along an edge.

The wires 232 are wired in a lattice shape crossing each other in the horizontal and vertical directions of the rectangular frame 231 while passing through or being fixed to the wire holes 231a, thereby forming a mesh shape.

Here, when wiring the wires 232 to the wire holes 231a, for example, all of the wires may be wired to each wire hole or may be wired one by one in every row, so that the size of the mesh can be adjusted. Therefore, since a space in which grass can grow can be secured between the wires, the growth of grass is not hindered.

The connecting rods 240 connect each side of the mesh plate 230 and the perforated base plate 210, and preferably are arranged at the same interval as the interval between the square holes 231 in terms of connection strength. good at Here, the connecting rod 240 may be connected in an inclined state due to a difference in height between the mesh plate 230 and the perforated base plate 210 .

On the other hand, since the connecting rod 240 has an inclined bar shape as shown in the drawing, if there is no structure supporting the lower part, there is a risk of damage when a weight load is applied from the upper part. It is preferable to support it, and it is more preferable to form a connecting rib between adjacent connecting rods 240 to prevent damage due to lateral load.

The upper cover 300 may include an upper perforated plate 310 and an X fitting portion 320.

The upper perforated plate 310 has the same size and appearance as the base perforated plate 210 except for the plurality of legs 220 and is laminated on the upper side of the base perforated plate 210, and a plurality of A square hole 311 may be formed. Here, the square hole 311 may be formed smaller than the size of the square hole 211 of the previous base perforated plate 210. Therefore, it is possible to prevent the protrusion formed on the sole of the user's shoe from coming off when stepping on it.

The X-fitting part 320 is fitted to each square hole 211 of the base perforated plate 210 while being provided at the lower part of the upper perforated plate 310, and the X-fitting part is diagonal of each square hole 211. By being formed in the direction, it is possible to exert a strong fitting force.

On the other hand, although not shown in the drawing, a portion of the upper end of the X-fitting portion 320 is configured to extend into the inside of the square hole 311 of the upper perforated plate 310 to fill a part of the space of the square hole 311. can do.

On the other hand, since the upper cover 300 corresponds to a practical walking board, it is preferable to coat a stain-resistant coating material to prevent staining and improve durability.

The coating agent is 20 to 30% by weight of polyol, 15 to 20% by weight of at least one functional alcohol selected from fluoroalcohol or silanol, 15 to 25% by weight of isocyanate, 5 to 8% by weight of blocking agent, 20 to 40% by weight of extender pigment , 3 to 10% by weight of an amine monomer, 1 to 3% by weight of an additive, and 1 to 3% by weight of an organometallic catalyst.

The polyol is a material added to impart functions such as tensile strength, tear strength, and abrasion resistance to the composition, and is preferably one or more from the group consisting of polyethylene glycol, polypropylene glycol, polybutylene glycol, and polyisoprene glycol. You can choose. At this time, when the polyol is included in less than 20% by weight based on the total weight of the composition, workability due to the increase in viscosity of the composition is lowered, and when it is included in more than 30% by weight, the mechanical properties of the coating film formed by curing are remarkably It is preferable to be included in the range of 20 to 30% by weight, since it may cause a decrease in workability and strength of the coating film. In one embodiment of the present invention, the polyol was used by mixing PP-3000 and GP-4000 from KPX Chemical.

The functional alcohol is one or more alcohols selected from fluoroalcohols and silanols, and is added to impart abrasion resistance, weatherability, and contamination resistance to the polyurea composition. Therefore, by including the functional alcohol, not only flame retardancy is imparted to the composition, but also mechanical properties such as heat resistance, cold resistance, weather resistance and aging resistance can be remarkably improved.

In addition, in the present invention, the isocyanate is hexamethylene diisocyanate trimer (HDT), isophorone diisocyanate (IPDI), cyclohexylmethanediisocyanate (H12MDI), methylene diphenyl diisocyanate (Methylene Diphenyl Diisocyanate, MDI) and toluene diisocyanate (Toluene Diisocyanate, TDI) characterized in that at least one selected from. At this time, the higher the isocyanate or NCO content, the higher the hardness or difficult to control the reaction, so the NCO content of the isocyanate is preferably 5 to 10%. In addition, the content of the isocyanate is preferably included at 15 to 25% by weight. When the isocyanate is included in less than 15% by weight, there is a problem in that the viscosity of the composition increases and the mechanical properties deteriorate, and when it exceeds 25% by weight, This is because the viscosity of the composition is lowered, the adhesive force is lowered, and the hardness is increased, which is undesirable.
