Abstract

The present invention relates to a turf module which has a structure having through holes enabling the stem of the turf to grow vertically and horizontally so as to provide a growth environment identical to the turf cultivated on an open field. The turf module is structurally stable regardless of shear load due to the static friction of a weight material and enables easy separation of a damaged block. Adjacent modules can be installed in a flat shape without any vertical dislocation.

Description

Grass module

The present invention relates to a lawn module installed on a pedestrian path, outdoor parking lot, playground, riverside or building roof, and in particular, has a through-hole through which the stem of the grass can extend in the longitudinal direction so as to have the same growth environment as the grass grown in the open field. The present invention relates to a grass module having a structure, structurally stable even by shear loads according to the static frictional force of a heavy object, and easily detaching a damaged module and allowing adjacent modules to be installed flat without shifting up and down.

In general, it is cured by placing asphalt or concrete for paving floors such as pedestrian paths, outdoor parking lots, sports grounds, riversides, and building roofs. In this case, it takes a long time to form the bottom surface, it is difficult to secure the green space because the growth of plants is impossible.

In addition, since the ground is blocked by concrete, drainage of rainwater, etc. is not smooth, and a separate drainage path is required. In particular, when the parking lot is used for other purposes, the concrete is crushed and removed to remove a lot of time and money. There is a problem that occurs.

As a means for solving the above problems, the case of paving the floor surface with concrete blocks or grass modules has been increased, and the blocks are able to withstand loads such as vehicles by curing cement, sand and gravel in proportion. It is designed to be able to minimize cracks and cracks.

An example lawn module is disclosed in Korean Patent Registration No. 10-1135225 and shown in FIG. 1. It includes a base portion disposed on the ground, a plurality of protrusions 20 are formed integrally protruding from each other at a predetermined height from the base portion 10, the groove 21 is formed by the protrusions 20 are spaced apart The soil is filled and configured to act as a plant growth space.

Since the grass module is made of concrete and does not secure a lot of gaps inside the block, the soil, water and air, which require vegetation of plants, are not easily accessible, so that the growth environment of the plants is still poor and not friendly to nature, and the drainage is not smooth in rainy weather. There is a difficulty in construction without specialized equipment at the time of construction with a high weight of 280kg per product, and there is inconvenience in replacement and partial repair.

In addition, there is a problem in that even when installed on the adjacent to reduce the flow to the left and right when installed, but when installed on the riverside can be lost not only plants and soil but also grass modules due to flooding the river.

Recently, a parking lot facility is constructed using a grass module that can drain rainwater and have a natural-friendly image by planting grass modules on the pavement and laying grass modules with holes in them. have.

An example of a grass protection block for a parking lot is disclosed in Korean Patent Registration No. 10-0762203 and shown in FIGS. 2A and 2B. The grass protection block 10 is a cover 30 for protecting the grass provided in the body portion 20 of the box-shaped open top, the body portion 20 is provided inside the body portion 20 It consists of.

The lawn protection block 10 is a protrusion 40 and the insertion portion 41 is formed on the outer surface of the body portion 20 so as to be easily coupled to the adjacent lawn protection block 10 in the lateral direction, adjacent grass The protective block 10 is to be connected to each other by the combination of the projection 40 and the insertion portion 41.

By the way, the grass protection block 10 as described above, which is a unit cell structure in which the grass is vegetated, the parking lot is formed in a state in which the grass protection blocks 10 are mutually separated from each other by the support 23. It is designed in such a way that the growth of the grass stem in the longitudinal direction is suppressed without considering the growth characteristics of the grass.

In view of the fact that the grass is propagated by the stem of the grass, in the closed module structure of the existing grass module, when the grass dies after external damage, only the soil remains in the structure until the grass is planted by manpower again. . In particular, in the case of a grass parking lot using such a grass module, the grass often dies due to physical pressure caused by a car and the damage caused by soot, and the grass does not play its original role as a living grass parking lot. It will cause an environmental adverse effect.

Especially. By blocking the adjacent protective block 10 by the support 23 prevents the grass stem from extending in the longitudinal direction, so that the grass does not grow at the boundary of each of the protective blocks 10, which is confused with the parking partition line There is this.

In addition, if any one of the grass protection block 10 is broken during use for the parking lot to replace it is not easy to remove the damaged grass protection block 10.

That is, the projections 40 formed on the outer surface of the grass protection block 10 should be lifted by sliding upwards. At this time, the plurality of protrusions 40 should be slid at the same speed so that the separation is not easy, so the replacement is not easy.

In addition, since the upper surface of the protrusion 40 and the insertion portion 41 is exposed to the floor of the parking lot, foreign matters such as soil are caught in the gap between the protrusion 40 and the insertion portion 41, so that the lawn protection block to be replaced ( 10) Difficult to separate

In addition, when the ground is not flat, there is a problem that any one of the grass protection block 10 is installed to deviate from the adjacent grass protection block 10 by the vertical sliding movement of the projection (40).

In order to solve the above conventional problems, a grass vegetation module (Korean Registered Patent No. 10-1643899) registered by the present applicant and registered on July 25, 2016 has been proposed.

3 to 5, the hollows 113 forming unit cells in which the grass is planted are configured to communicate with each other through the stem extension port 112, so that the grass is opened even when the grass is damaged. Through the stem extension port 112 so that the underground diameter of the grass can be recoated, there is an effect of increasing the grass coverage.

Nevertheless, the turf vegetation module has a structure in which the upper frame 200 and the lower frame 100 are separated, which is inconvenient in assembling construction, and the upper and lower fasteners 211 and 111 in the portion of the vehicle pass by weight. Deformation damage occurs and there is a problem that noise such as squeak occurs.

In addition, as shown in the colored portion of Figure 3, the unit cells consisting of the support 110 is formed independently of each other formed by shearing force (shearing force) when the parking of the weight of the vehicle repeatedly acts to the left and right to fatigue damage There is a problem that occurs.

In addition, when constructing a parking lot by adhering the vegetation modules to each other, there is no connection structure between the adjacent vegetation modules, it requires a considerable work time to align the installation on the floor so that the height difference between the adjacent vegetation modules does not occur.
