Description

Safety rubber plate for children playground and construction method its}

The present invention relates to a rubber flooring material and installation method for children's playground with safety, and more specifically, by using a mixed material such as waste tires pulverized product, urethane binder, etc., it can be environmentally friendly and secure safety and problems such as bending, torsion The present invention relates to a rubber flooring for a children's playground and a method of installing the same, which can significantly increase durability.

Recently, a lot of blocks using urethane, rubber, or waste tires have been developed, and some of them have been commercialized in pedestrian walkways.

Such sidewalk blocks are durable and elastic, and provide more environmentally friendly sidewalk blocks through micropores inside the blocks.

For example, Korean Utility Model Registration No. 288078 "Rubber Block" discloses a pedestrian sidewalk block as described above.

However, in the case of the sidewalk block made of the above-mentioned elastic body, air or moisture can pass therethrough, which is excellent in terms of environment-friendliness, but does not have sufficient elasticity, so a space of high safety, such as a children's playground, is maintained. Is difficult to use as a flooring material.

In other words, the rubber blocks that do not have sufficient elasticity when children fall or fall from the high playground when playing on the playground is insufficient in terms of preventing children's safety accidents.

For example, children's playgrounds nowadays have altitudes ranging from 1.2m to 8m in height.

Falling accidents due to carelessness create great risks.

If you fall to the ground due to carelessness, you won't be seriously injured if you absorb the shock from the ground.

In order to ensure safety, children's playgrounds have recently been installed with shock absorbing floor pavement materials, so as not to suffer great damage from falls.

However, despite these attempts, the damage caused by accidents is not so much improved.

The reason is that the shock-absorbing bottom packaging material does not sufficiently absorb the impact because it absorbs the impact by reaction rather than by bending deformation.

When a shock is absorbed simply by reaction, it is almost the same effect as being bounced back by the repulsive force. Therefore, the child falling down receives the shock in the form of repulsive force. It is also triggered.

Currently, the products being constructed in children's playgrounds are mostly made by compression molding of urethane binders consisting of particles having a lower layer of 6 to 7 mm and an upper layer of 1 to 3 mm.

This has the effect of improving permeability and walking feeling and reducing cost, but the structure of the upper and lower layer particle bonding is different from each other, so that the lower layer is wetted with water or moisture for a long time and the upper layer is contracted and relaxed while reacting sensitively to the temperature change of the atmosphere. The process is repeated, and this process causes distortion and warpage, which hinders aesthetics and raises the issue of safety, which results in harm to the original advantages of safety, permeability, and eco-friendliness. The situation is facing.

In addition, products currently constructed generally have a standard of 500 × 500 × 50 (mm) and are expected to have drainage and safety effects by digging grooves of 5 to 20 mm in width at a depth of about 5 to 20 mm from the bottom of the lower layer. In addition, it also has a structural limitation that it is not easy to prevent warpage and does not meet the standards required by users and contractors, and thus cannot effectively respond to child safety accidents.

Therefore, the present invention has been devised in view of such a point, and it is not only environmentally friendly using mixed materials such as waste tire pulverized products or urethane binders as flooring materials, but also greatly improves safety by improving the cushioning characteristics through structural improvement of the flooring materials. By reinforcing, the object is to provide a rubber flooring for a children's playground having a safety that can prevent children's safety accidents.

In addition, another object of the present invention by applying the binding structure between the flooring material in contact with each other during the construction of the flooring, it is possible to prevent deformation, such as warping, bending due to impact or environmental changes, thereby improving the structural strength and durability of the flooring It is to provide a rubber flooring installation method for children's playground with a safety that can significantly increase.

In addition, the present invention by providing a variety of expressions, such as patterns, logos, colors on the surface of the flooring material after completion of construction, to provide a rubber flooring material and installation method for children's playground having a safety that can give children more friendly and attractive There is another purpose.

The female connecting member and the male connecting member to be made, characterized in that formed in the bottom surface of the rubber block and has a shape including a plurality of shock absorbing pillar having an inner diameter groove and performs a shock absorbing function.

Here, the shock absorbing column is arranged in a regular or non-aligned irregular form to match the five and the heat while maintaining a constant distance from each other on the bottom surface of the rubber block to apply a form that effectively performs the shock absorption function and drainage function can do.

On the other hand, rubber flooring installation method for a children's playground having a safety according to an embodiment of the present invention for achieving the above object is a rubber block in the form of a square plate including a female connecting member and a male connecting member formed on each edge of the block. Then, the rubber blocks are connected horizontally and vertically on the concrete foundation or grounded ground while connecting the male and female connection members between the rubber blocks adjacent to each other in all directions to treat the entire rubber block as one surface. Characterized in that the process consisting of the binding.

Here, in the case of the rubber block, by using a rubber block of the form which is formed on the bottom surface of the block and includes a plurality of shock absorbing pillar having an inner diameter groove and a shock absorbing function, it is possible to ensure an effective cushioning structure and a smooth drainage structure.

In addition, as a work to close the boundary after the rubber block is installed over the entire children's playground, the outermost rubber block has a male and female connecting member and a male and female connecting member of the rubber block on one side, while the upper surface is inclined. The method may further include a process of connecting and installing a shock absorbing boundary block.

4) Since the surface of the flooring material is expressed in various patterns, logos, colors, etc. after completion of construction, it can give children more friendliness and charm.

5) By having a columnar shape of about 50mm on the bottom of the flooring material, the drainage and flow of water such as rainwater can be made smoothly and quickly.

6) By providing a shock-absorbing boundary block of waste tire material + binder material that can replace the existing concrete boundary stone, it is possible to promote the safety of children and fall accidents when falling into the playground due to the inclined structure. Can be prevented.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 and 2 is a perspective view showing a unit block of a rubber flooring for a children's playground according to an embodiment of the present invention.

As shown in Figure 1 and 2, the unit block of the rubber flooring material, that is, the rubber block 10 is a block of a rectangular plate shape, the surface exposed after installation may have a variety of colors, patterns, logos, etc. In addition, the appropriate combination of colors, patterns, logos, etc. can provide a space for children to be more interesting.

Such a rubber block 10 can be manufactured using waste tire chips, which are usually pulverized waste tire chips or various rubber resins, mixed with a urethane binder, and melted, and then molded through a mold into a desired shape. It can be prepared by.

At this time, when the rubber block 10 is manufactured, waste tires can be recycled using waste tire chips or the like to prevent environmental pollution. Also, when the waste tire chips are kneaded and extruded from time to time, appropriate fine pores are formed. These micropores can be formed to allow the distribution of air and moisture as well as to provide a flooring block with higher elasticity.

Here, a method of properly mixing waste tire chips, urethane binders, color pigments, curing agents, other fillers, and the like for molding rubber blocks may be adopted without particular limitation as long as they are commonly known in the art.

Since the rubber block 10 is installed in a form in which the whole block is integrally bound when the children's playground is installed, the rubber block 10 has a structural feature that can actively cope with deformation such as warping or bending.

To this end, a pair of female connecting members 11 and male connecting members 12 are formed at each edge of the rubber block 10, that is, at four edges of the rectangular plate shape.

For example, one rubber block 10 is provided with a total of four pairs of male and female connecting members 11 and 12, one pair on one surface.

The pair of male and female connecting members 11 and 12 are formed side by side at one edge of the rubber block 10 one by one, and the male connecting member 11 and the male connecting member are along the edges of four surfaces as a whole. The members 12 may be alternately repeated one by one.

In particular, the female connecting member 11 is formed to protrude outward from the side of the block, so that when connecting between blocks to cross over to the area of the other neighboring block and coupled with the male connecting member 12 has another block therein In the case of the male connecting member 12 is formed to protrude downward from the inside of the block edge.

The male and female connection member 11 may have an engagement form in which the male connection member 12 is fitted into the seating groove 15 of the female connection member 11.

In some cases, by applying a pollution-free silicone adhesive to the coupling portion of the male and female connecting members 11, 12 can be more firmly bonded.

At this time, since a certain gap 16 is formed at a portion other than the portion where the male and female connecting members 11 and 12 engage with each other at the interface between the blocks, a shock absorbing function and a cushioning function can be performed together. Can be.

Accordingly, the rubber blocks 10 adjacent to each other in all directions can be installed as a single integrally coupled structure through the coupling structure between the male and female connecting members 11 and 12, resulting in external force or environmental change. Warping, twisting and the like can be prevented.

The rubber block 10 may exhibit a shock absorbing function for the safety of children.

That is, by providing a plurality of shock absorbing pillars 14 in the rubber block 10, it is possible to sufficiently prevent and prevent safety accidents that may occur due to children falling or falling in an area where safety accidents may occur frequently, such as a children's playground. have.

To this end, the bottom of the rubber block 10 is formed with a plurality of pillar-shaped buffer pillar 14 having an inner diameter groove 13 is formed to protrude a certain height from the bottom.

The buffer columns 14 are arranged in a regular form in which the rows and rows are aligned with each other while maintaining a constant distance from each other on the bottom of the block, or are arranged in an irregular shape that is not aligned, and have various shapes such as a cylinder shape or a polygonal shape. It can be made of pillars.

For example, a cylinder-type buffer column 14 having a specification of an outer diameter of 50 mm, an inner diameter of 20 mm, a flesh thickness of 15 mm, a height of 50 mm, an inner diameter groove depth of 35 mm, and a gap of 15 mm may be applied.

Accordingly, when the child falls or falls on the upper part of the rubber block, it absorbs the primary shock from the cylinder, continuously absorbs the secondary shock from the inner diameter groove of the cylinder, and continues to the third order at the interval (gap) between the cylinders. It can absorb shock.

That is, the shock applied to each cylinder is transmitted from the longitudinal direction (vertical direction) to the transverse direction (horizontal direction) by the dispersion action exerted by the inner diameter grooves and the voids, so that all the impacts can be absorbed into the respective voids and spaces.

Therefore, the child who falls on the upper portion of the rubber block does not feel a great shock to the body by the shock absorption and dispersion action of the buffer column.

In addition, the present invention provides a shock absorbing boundary block 20 of rubber material that can replace the existing concrete boundary stone when the outer finish of the rubber flooring.

The shock absorbing boundary block 20 has a female connecting member 21 and a male connecting member 22 that match the female connecting member 11 and the male connecting member 12 of the rubber block 10, respectively. It has a side part and consists of a shape which has the upper surface which consists of the inclined surface 23.

Such a shock-absorbing boundary block 20 is arranged in contact with the rubber block 10 disposed at the outermost side, and is bound to the rubber block 10 side using the male and female connecting members 21 and 22. It is installed in the form.

In particular, in the case of the shock absorbing boundary block 20 by having an inclined surface 23, it is possible to prevent the fall accident fall when children enter from the outside to the inside of the playground.

3 to 6 are a perspective view, a bottom view and a sectional view showing an installation state of a rubber flooring for a children's playground according to an embodiment of the present invention.

As shown in Figures 3 to 6, prior to the installation of the rubber flooring can be carried out to lay the foundation.

For example, by laying a permeable layer (aggregate) on the ground layer or by forming a concrete layer and an asphalt layer, a rubber flooring material is installed thereon.

First, a rubber block 10 having a rectangular plate shape including a female connecting member 11 and a male connecting member 12 formed at each edge of the block is prepared.

In this case, the rubber block 10 may be formed on the bottom surface of the block and has an inner diameter groove 13 and may include a plurality of shock absorbing pillars 14 having a shock absorbing function.

Next, while connecting the male and female connecting members 11 and 12 between the rubber blocks 10 neighboring each other in all directions in a way that the rubber blocks 10 are connected one by one, the rubber blocks 10 are transversely and vertically on the foundations. Connect in parallel (viewed from the plane).

The rubber flooring installed in this way may be a structure in which the entire rubber block is integrally bound while being treated with one surface.

Subsequently, in order to finish the outer surface of the rubber flooring, the shock absorbing boundary block 20 is disposed in the outermost rubber block 10, and the rubber block in the form of connecting by using a male and female connecting member ( 10) by binding the shock absorbing boundary block 20, the installation of the rubber flooring in which the playground boundary is finished with the shock absorbing boundary block 20 is completed.

As a finishing operation, after the completion of the construction of the rubber block 10, a pattern or a logo may be expressed on the surface of the block, and then the coating may be finished with urethane paint.

In the case of the rubber flooring installed in this way, by having a buffer column of a certain height on the bottom surface, the spaces are wide and spaces between them are not well drained playground (soil-rich sand, silica sand, stone powder, concrete, etc. as a lower layer or The drainage and flow of water, such as thick water, can be extremely smooth and fast in places where the overall gradient is less than 5 ° and in the playground where drainage facilities are installed outside the boundary of the site.

This is because water is accumulated in the lower layer of the product because it is not drained in the existing elastic mat or the mat itself absorbs moisture and water for a long time and the urethane binder in the lower layer causes partial hydrolysis to cause heat shrinkage of the upper layer ( It is associated with the action of sunlight, ozone, etc. to reduce the sharp bending phenomenon.

All existing elastic mats are produced and constructed so that the entire bottom surface of the product is in close contact with the lower ground plane, but the rubber flooring material of the present invention has a certain gap even between the columns where the male and female connecting members are not connected (adhesive). The shock absorption effect of can be prolonged and obtained in parallel.

All current playgrounds are using concrete boundary stones, and thus safety is not taken into consideration. However, the present invention uses waste tire materials to provide rubber flooring materials and shock absorbing boundary blocks that meet the specifications and specifications. Improve children's safety more effectively

In addition, in the present invention, after cutting the lower end of the column and the connecting portion (male and female connecting member) of the bottom of the block on the contact surface of the boundary stone in consideration of the case of construction in the existing concrete boundary stone, it can be installed by covering the existing boundary stone with a part of the block , You can reconsider your safety.
