It is characterized by being one of the axial meshes.

A braille tile construction method according to still another aspect of the present invention includes a step of marking out a construction surface, a step of cleaning and applying a masking tape, a step of applying a primer or a dedicated adhesive, and a reinforcing member. Step, curing and drying step, applying adhesive step, braille tile attaching step, bleeding air, checking air mixed state, and tapering the end portion of the braille tile Characterized in that the reinforcing member is any one of vinylon biaxial mesh, vinylon triaxial mesh, vinylon tetraaxial mesh, aramid biaxial mesh, aramid triaxial mesh, aramid tetraaxial mesh. ..

According to the present invention can provide a method of constructing high have Braille tiles intensity with increased resistance to pressing force from the surface.

It is a block diagram of a Braille tile concerning one embodiment of the present invention. It is a figure which shows the procedure of the construction method of the Braille tile which concerns on one Embodiment of this invention.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows and describes a configuration of a braille tile according to an embodiment of the present invention. More specifically, FIG. 1A is a plan view of the braille tile, and FIG. 1B is a cross-sectional view of the braille tile taken along the line AA in FIG.

As shown in these drawings, the Braille block 1 according to the present embodiment has a flat portion 3 made of a rectangular parallelepiped having a thickness in this example, and information is projected on the surface of the flat portion 3. The plurality of protrusions 2 are arranged so as to be arranged at a predetermined interval. The reinforcing member 4 is embedded in the flat surface portion 3. The reinforcing member 4 is embedded in a size that reinforces the entire flat surface of the flat surface portion 3.

As described above, according to the present embodiment, the thick flat surface portion 3 and the plurality of projection portions 2 arranged on the flat surface of the flat surface portion 3 at a predetermined interval are molded with either resin, synthetic rubber, or a concrete block. The braille tile 1 configured as described above is characterized in that the reinforcing member 4 is embedded in the flat surface portion 3. At the time of molding, the reinforcing member 4 can be molded as a whole while being embedded in the flat surface portion 3 by gently dropping it into the resin or the like poured into the mold. As the resin, MMA or the like can be used, but the resin is not limited thereto.

As the reinforcing member 4, a vinylon biaxial mesh, a vinylon triaxial mesh, a vinylon tetraaxial mesh, an aramid biaxial mesh, an aramid triaxial mesh, an aramid tetraaxial mesh, etc. can be adopted, but from the viewpoint of strengthening pressure resistance. In particular, vinylon triaxial mesh and aramid triaxial mesh are preferable.

According to the above configuration, it is possible to provide a braille tile having high strength with improved resistance to pressing force from the surface.

Next, with reference to the flowchart of FIG. 2, the procedure of the braille tile construction method according to the embodiment of the present invention will be described in detail.

First, the construction surface is marked (S1). Inking is wide and 10 mm around the braille tile. Then, after cleaning, a masking tape is attached (S2). Although a blower or the like is used for cleaning, the groove is especially cleaned. Stick the masking tape on the outside of the cut groove. At this time, be careful that the tape does not protrude outside the groove. The masking tape does not have to be peeled off after applying the primer. Since the edge is cut by the groove, it may be removed after the tile is attached.

Subsequently, a primer or a dedicated adhesive is applied to create a base (S3). Apply a thin layer of primer or special adhesive so that there is no unpainted residue on the entire installation surface. For example, about 20 m is quickly applied with less than half of one set (2 kg).

Next, a reinforcing member is installed (S4). This installation is done quickly before the previously applied primer or dedicated adhesive has dried. For example, adjacent reinforcing members are installed with an interval of about 5 to 10 mm. As the reinforcing member, a vinylon biaxial mesh, a vinylon triaxial mesh, a vinylon tetraaxial mesh, an aramid biaxial mesh, an aramid triaxial mesh, an aramid tetraaxial mesh, or the like can be adopted, but is not limited thereto.

Then, curing drying is performed (S5). Next, a dedicated adhesive for tile attachment is applied (for example, one set of eight adhesives is recommended to be attached) (S6). After the primer is completely cured, apply it evenly and evenly with the special combing iron. At this time, when the special fibers as the reinforcing member are scratched by the comb-like iron, the fibers are unraveled, so the trowel may be slightly floated and the adhesive may be applied. Carefully apply the adhesive so that the groove is fully filled.

Then, Braille tiles are pasted (S7). Apply braille tiles quickly to follow the previous application of adhesive. At this time, it is advisable to have joints of about 5 to 1 mm in the connection portion in consideration of raising of the stickiness.

Next, air is removed (S8). Specifically, roll the roller to bleed air on the back of the braille tile.

Then, the mixture of air is confirmed (S9). If air is mixed in the back of the braille tile, it will break or break, so it is recommended to hit it with a hard object such as a spatula pattern and check it by the sound. It is recommended that the air mixing part be completely evacuated from the center to the outside. After removing this air, tap it again to check the air release condition. In addition, since it is installed on the special fiber as the reinforcing member, air is likely to be mixed in the stitches, so it is advisable to carefully perform the steps S8 to S9.

In this way, the taper processing of the end portion of the Braille tile is performed (S10). Specifically, in addition to the usual taper treatment, the groove is sufficiently filled with the adhesive. Since the dense-grained pavement does not have a water-permeable function, it is advisable to remove the joint adhesive every few sheets with a joint spatula to secure a water channel.

This completes the construction.

As described above, according to the braille tile construction method according to the embodiment of the present invention, by inserting the reinforcing member (special fiber) such as the triaxial mesh between the pavement material and the tile body, the unevenness of the braille tile can be obtained. Can be reinforced so that it does not collapse. This means preventing a situation in which the unevenness is loaded with a load and crushed when the vehicle crosses.

Although one embodiment of the present invention has been described above, it goes without saying that the present invention is not limited to this, and various improvements and changes can be made without departing from the spirit of the present invention.

For example, as the reinforcing member, it is needless to say that various special fibers can be adopted in addition to the above-mentioned vinylon triaxial mesh, aramid triaxial mesh and the like.
