Description

DETAILED DESCRIPTION OF THE INVENTION Regarding the method, membranes are also a suitable method, especially when installed on the roof of a building.

Recently, the applications of artificial turf boards have increased significantly, and they are now being used in large quantities mainly in various ball game facilities.

Simply laying these artificial turf boards has drawbacks such as poor cushioning properties and the possibility of injury to players, so the applicant has decided to cover the artificial turf boards with a covering material such as sand. We have proposed a pseudo-grass mat.1 This pseudo-grass mat is becoming popular at tennis courts and the like.

Typically, sports stadiums, especially tennis courts, have a base built by building a roadbed and then sequentially layering layers of granulated crushed stone and coated asphalt or concrete.

Furthermore, the roof of the building does not have such a foundation, but is simply a foundation made of poured concrete.

Recently, as an effective use of the rooftops of buildings, a variety of all-weather sports facilities have been constructed with fences placed on the rooftops for use in tennis, volleyball, etc.

However, even in these rooftop sports facilities, there is no particular construction method, and the only way to do so is to simply press urethane mats or rubber grips.

On the other hand, on rooftops, there were problems with their waterproofing, and creating a lightweight and reliable waterproofing system was also a challenge.

As a result of various studies, the inventors of the present invention found that there is no construction method that can waterproof a rooftop and at the same time provide a comfortable gable at the same time as building a roof-top sports facility. We focused on lightweight cellular mortar that has excellent insulation and heat retention properties, and also has no water absorption.
The present invention was achieved based on the knowledge that this lightweight cellular mortar can be used as a base for artificial lawn boards at the same time as waterproofing.

An artificial lawn board having thin strips made of a corrosion-resistant base material attached in a raised manner is laid on the surface of the lawn, and the tips of the thin strips are covered with sand or other covering material. This is a construction method for artificial lawn boards.

The configuration of the present invention will be explained in detail below.

First of all, regarding the foundation, in the case of the roof of a building, the surface on which the concrete is poured becomes the foundation (c), so there is no need to prepare a special foundation.

Next, if it is to be carried out on flat land, the upper grained crushed stone layer (Q) with which the roadbed has been constructed is dug and the subgrade layer Q) is laid down, and a layer of painted asphalt or concrete (3) is laminated on top of it to form the base. do.

Cleat) has a specific gravity of /, O~/6g, and a compressive strength of /50-200Kgf7/a door is most suitable.

Next, to explain the on-site casting method for lightweight cellular mortar (or cellular concrete), a diluted air foaming agent containing animal protein as a main component is diluted with water, and a diluted solution is pumped into the nozzle using a compressor. The air bubbles formed through the atari are injected into the ready-mixed mortar (or concrete) in the agitator mounted on the agitator truck, and the lightweight foam mortar (or foam concrete) made by stirring is pumped with one squeeze pump. The concrete is then forced into the base and placed on the base.

Therefore, the workability is extremely good, and the foamed mortar (or foamed concrete) made has closed cells, and the pouring thickness is usually 30-200mm, with wooden frames or blocks placed around each drainage ditch. This is very important.

Artificial grass boards are laid on the lightweight cellular mortar (or cellular concrete) cast in this way. A slit yarn made by cutting a film of polypropylene or the like into thin strips is used, and a corrosion-resistant base piece (B) K is flocked and attached to make it stand up like a nap.

The length of the raised portion of this strip is usually 3-23 mm.

Once the above work is completed, dry sand with a particle size within the range of 100 mesh to /4' mesh is applied as a covering material (7) to lrO% of the length of the raised part of the strip.
The artificial lawn board construction method of the present invention is completed by coating the artificial lawn board to a certain extent.

As mentioned above, the present invention involves laying an artificial grass board on the surface of concrete or asphalt, on which ten thousand strips of a corrosion-resistant base material are attached in a brushed manner. Since this is a method of constructing artificial lawn boards characterized by coating them with sand or other covering material, it can be ideal for use as an athletic field.

In the present invention, an inventive step has been found in that lightweight foam mortar (or foam concrete 1, 1-') is placed under the artificial lawn board, and therefore, it is particularly suitable for use on the roof of a building. When constructed, the eaves do not put any weight on the building itself, and it has insulation properties and does not absorb water.
It is ideal for waterproofing rooftops; 1) it retains heat; it protects your feet from getting cold when used in the winter; 1) it also makes an ideal base for sports stadiums. .
