Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the provision of a pavement block having a cushioning rubber layer with excellent abrasion resistance and weather resistance properties on the walking surface, and in particular, a block material having a unique loose Tff structure utilizing waste tire rubber material. It is something.

In the past, this soul block material usually did not have a buffering function, and the surface was directly made of concrete. Concrete block materials are used in many meters for paving, etc. because their forming costs are relatively low and NHS construction is easy, but they have poor impact and wear resistance properties. In addition to having difficulties in the following, it is difficult to be considered as a paving material that is necessarily satisfactory in terms of exterior function and buffer function.

In this regard, it was planned to install coating materials that partially covered the buffer, but it took about 4 workers and 1 worker to install the material.
On the other hand, although it requires a lot of effort, it often induces the separation of the stakeout '+M', and is also said to be the cause of unexpected accidents such as watery eyes and slips. Also, when pasting such cushioning sheet materials, etc., since the sheet materials are easy to eat,
Photo molecules (unless they are bonded) will cause peeling, wrinkling, tearing, or slipping of the sheet material itself.

The buffer pavement block according to the present invention was devised in view of the disadvantages of the conventional pavement materials, and has a buffer rubber layer integrally formed on the block surface in advance, and
This rubber buffer layer is prepared by recycling discarded tire rubber and has a unique ridge impact structure. MX, in that a ridge layer is welded and shaped so as to leave a bonding gap between the chip-shaped crushed waste tire rubber materials, and is provided on the upper surface of the concrete block.
The following specific examples and considerable design changes accompanying the examples are planned.

A typical embodiment of the buffer pavement flock according to the present invention will be explained below with reference to the accompanying drawings. It has dimensions. The cushioning material (2), which is integrally laminated on the surface of the block (1), especially on the walking surface, is provided by recycling waste tire rubber material, and it further ensures the mutual integration. With the intention of The tire rubber material is integrated.

Therefore, this buffer iO (2) can be integrated with the block (1) by placing waste tire rubber material on the top surface of the formed concrete block (1) and directly heating and vulcanizing it. In the case where the cushioning material (2) is fixed in one piece, and after the cushioning material (2) is vulcanized and molded in advance using waste tire rubber material, this cushioning material (2) is placed into the mold! It was planned that concrete would be placed in the concrete to obtain the block (l), and in either case, it would be ensured by the binding during vulcanization of the rubber and the binding during setting of cement. The two are fixed and integrated.

In addition, the cylindrical edge of the block (1) is chamfered with a tapered surface fl.
)bL, or the laminated peripheral side edge of the buffer material (2) is similarly made into a chamfered tapered surface (2)a, and joints 131fm between the paving blocks are formed separately.

Next, the cushioning material (2) which is an integrally laminated material is made by reusing discarded tire rubber material, and this discarded tire material is crushed into chips using an appropriate means such as a chopper or shirring, and the crushed agglomerates a% Heating a by an appropriate method such as steam vulcanization, press vulcanization, ultra-high frequency vulcanization, etc.
By vulcanization, the surfaces of the lumps aS-a are fused to each other and become integral, leaving gaps il b and b between the lumps a%a.

The purpose of this vulcanization method is to effectively utilize the unique wear-resistant properties, weather-resistant properties, and custom-made cushioning properties of waste tire materials, which are the raw material, in the trowel material (2) without reducing them as much as possible. This book is specifically designed to avoid the dry weakening of the material itself that accompanies complete bath melting and revulcanization.

Next, by making the structure of the cushioning material (2) into a connected shape of blocks a to a, the cushioning material (2) itself has a cross-linked structure, and in addition to the elasticity of the material, the cushioning material The 1-chome was promoted to the 4-chome, and its anti-static resistance stitching was dramatically increased.

Also, insulation in paving materials can be improved by intervening such gaps.
The sound absorption function is effectively promoted, and the sliding contact noise induced on pavements, competition courts, etc. and solar heat are effectively blocked.

Furthermore, the presence of gaps and the separable structure of the joint edge at the joint (3) facilitate the permeation of rainwater into the ground, effectively trapping rainwater on the paved road surface. It is said to be particularly effective in preventing water damage and conserving groundwater. In addition, the permeation of rainwater promises to reliably prevent slipping accidents on the pavement edges, but to prevent such slipping, a separate block cushioning material (2) is used.
It is planned to layer oil sand (4) on the surface, or to make the rubber material itself wave-like raised (t5)L, or to raise it (6), and to attach foam particles (7). be.

The buffer 1tiIII block according to the present invention has a unique construction, in particular, a concrete block and a buffer material 12) are integrally constructed, and when these blocks are laid, the pavement, court or By configuring the floor surface, etc., specific 7SL' effects of the above-mentioned characteristics were obtained.

In particular, since it has become possible to provide roads and courts with a unique slow-rolling structure using the same construction as the four paving blocks, construction costs and repair costs can be reduced. Especially expected. Moreover, by integrating with the block body, the inconvenience of peeling and twisting of the surface cushioning material (2) is avoided, resulting in a stable, uniform and smooth surface.
O) +YJe was promised to be provided.

Furthermore, in the case of collisions between blocks, a buffer material (2
), accidents such as breakage and breakage can be avoided, and the additional impact force applied to the block portion when a load is applied is reduced.

In addition, as a general paving material, it is considered to be ideal for coloring or patterning, and is expected to have unique value.

Next, due to its high p$ resistance on the contact surface, it can be used not only as a paving material for competition courts, but also as a means of paving special road surfaces such as car access paths and parking lots. This is also a book that has been proven to have the desired effect.
