Description

  For the visually impaired by the Heart Building Act and the Easy Town Development Ordinance, installation of braille urns is mandatory on the entrance of buildings and sidewalks. It provides a braille bag that is very easy to construct and inexpensive, and that lasts a long time.

  By recycling thinned timber and waste wood, the technology of making the deck material by molding it into finely crushed wood and molding it has become more robust and cheaper than the previously used natural wood.

  This flooring is molded into a hollow so that it can be cheaply constructed. By making it hollow, the weight becomes lighter and less material can be manufactured, and because it becomes lighter, the transportation cost is reduced and it is strong against water. Although it was often used on the waterside such as the bay area, it is cheap and strong, so it has recently been used in many buildings in the city.

  When building or renovating a building, Braille tiles will be installed for visually impaired people, but these Braille tiles installed on this floor frequently come off in the case of the bonding method, and the screw method (Patent Document) In the case of 1), since the thickness of the flooring is as thin as 6 mm, the insert nut cannot be used, and it is sewn directly to the flooring with screws, but the flooring becomes thin due to the thinness of the flooring. At a later date, the screws are loosened and dangerous.

  In the case of the screw method as shown in Patent Document 1, since the fixing screw is loosened little by little and it becomes a dangerous state, repair work is frequently performed. Further, in the method as shown in Patent Document 2, it is necessary to prepare a receiving material for fixing braille wrinkles at the lower part of the floor material, but it is impossible to prepare a recycled wood deck. In the method of Patent Document 3, the receiving material itself for fixing the Braille ridge is made of a large material, and it is impossible to charge the material to the lower part of the deck material.

Formed recycled hollow wood deck is constructed with 2m or 3m long products, the main component is made of resin, and the materials of braille are various such as stainless steel, brass, aluminum, resin, etc. The standard is determined by JIST9251 The surface of the reclaimed wood deck that does not have the property of strongly adhering to the adhesive is difficult to wear, and when attached so as to cross the long, the braille folds as shown in Fig. 1-B If you start to straddle several recycled wood decks, and if people or things pass through and load is applied, the deck will be long.
Since the adhesive surface moves apart, the adhesive cannot endure the movement in the opposite direction, and the adhesive peels off and the braille is peeled off, often causing repair work.

  It is necessary to prepare a receiving material for fixing the braille tiles at the bottom of the flooring material, but it is impossible to prepare a recycled wood deck. In addition, the receiving material itself for fixing the braille jars was made of a large material, and it was impossible to charge the bottom of the deck material.

If the flooring is stone, tile, concrete, etc., a hole is made in the flooring and the adhesive is poured into the hole where the adhesive is made and fixed. However, in the case of a hollow wood deck, this method is not possible. There is only a method of simply applying an adhesive on the back surface of the Braille heel where the surface of the sword is in contact with the Braille heel, and there is a concern that it will be easily peeled off at a later date. We have devised techniques and methods that can solve such problems.

The technology in the invention is to provide a safe Braille rod after it has been used for a long period of time after the Braille rod is attached to the recycled hollow wood deck, and the repair work is reduced.

  When attaching the guide Braille 鋲 to the artificial wood hollow wood deck, insert a resin cylinder into the mounting hole of the artificial wood hollow wood deck and push it down to the bottom of the hollow portion of the wood deck. This is a method of attaching the braille rod to the hollow wood deck floor material in which the adhesive is filled and the braille heel portion is inserted and fixed to the portion.

  The cylindrical body made of resin has a cylindrical shape with a thickness of 0.1 mm to 1.5 mm, the diameter of the cylinder is 0.1 to 2 mm larger than the diameter of the hole, and the height of the hollow portion of the hollow hollow wood deck is 0. Use one shorter than 1 mm. The adhesive to be injected is an epoxy system that is usually used, and fills the hole and the cylindrical body and injects to a position half of the hole.

  In the Braille scissors of the present invention, a portion corresponding to the foot of the Braille scissors indicated by 4 in FIG. 3-A is made of a screw, a tap is cut on one Braille scissors, and the hollow of the wood deck indicated by 5 in FIG. By changing according to the depth, the adhesion area can be increased.

  The installation method of the braille rod of the present invention is a completely new method that has never been seen before, 2 in FIG. 3-B shows a hole drilled by an electric drill, 6 in FIG. 3-B is much more than 2 holes It is an elevation surface of a large-diameter resin cylinder.

The resin cylinder is cut to a hollow depth and is also cut in the vertical direction. The cylindrical body made of resin can be cut in one place in the vertical direction to reduce the diameter. When fed downward from the hole, the diameter is restored, and the length falls to match the height of the space. There is nothing to do. By installing the resin cylinder, the adhesive of 7 in FIG. 3B can be injected to fill up the hole in the deck, 8 in FIG. 3-C shows it.

A, B, and C in FIG. 3 are process diagrams, and show the braille marks before bonding. After filling the adhesive material up to the hole in the deck, the guide braille marks are installed. 1A and 1B are completed cross-sectional and plan views.

By filling the adhesive to the entrance of the hole and solidifying it, the Braille font is integrated with the wood deck and does not peel off.
Recycled wood hollow wood deck material is a new technology for the purpose of reusing thinned and waste wood, so it could not be handled by the conventional technology of attaching braille tiles.

Braille fonts for visually impaired people are installed for the purpose of barrier-free, so it is determined by law that they should be installed so that they can be used easily regardless of the material of the flooring.
Inevitably, the Braille rods are attached by straddling a plurality of deck materials. However, the repair work does not occur because the construction is performed according to the present invention, and the construction labor and time are shortened.

  Hereinafter, the embodiment of the present invention will be described in detail with reference to the drawings. The diameter of the resin-made cylindrical body 6 in FIG. 2 is larger than the diameter of the hole shown by 2 in FIG. Normally, it cannot be installed in the lower space 5 shown in FIG. 3B, but the diameter can be made smaller than the diameter 2 of the hole by cutting and squeezing one place in the vertical direction.

  This resin cylindrical body is cut by adjusting the length according to the depth of the space of the wood deck. When this resin cylinder is stabilized in the space, epoxy adhesive can be injected into the resin cylinder from the two holes and filled to the entrance of the hole in the wood deck as indicated by 8.

We will explain the construction results related to the installation method of Braille 鋲 to the hollow wood deck flooring. At the shopping center in the bay area, the floor on which the shoppers walk is made into a wooden deck so as to capture the seascape.
Before the development of the artificial wood regeneration type wood deck, it was constructed with natural wood, but there are many requests that it does not last long due to salt damage of the sea breeze, etc. and that it wants to use environmentally friendly recycled products, and the artificial wood regeneration type is the mainstream Became.

There was a construction that connects the parking lot and the sales floor with a pedestrian bridge because the roadway crosses the multistory parking lot and shopping area. For visually impaired people, Braille guidance was necessary from the parking lot to the reception desk at the sales floor.
The pedestrian bridge is 5m wide and 40m long, and the hollow wood deck is 3m in size, so it was constructed with 2m cut to 3m against 5m wide. The braille guide rod is about 30 cm, but a length of 40 m is attached so as to cross a plurality of wood decks.

  People who come by car will use the pedestrian bridge to go back and forth, which will be a lot of traffic, the deck bends largely due to the large number of people, but it was released immediately in the conventional Braille fence construction, but epoxy adhesive The agent is hollow and solidified with the stick that is the foot of the braille rod, and it does not peel off because it is integrated with the deck.

  The artificial wood deck has excellent durability, so it is widely used on the site of buildings. It has little reflection in summer and has an energy saving effect. ing. The use of deck materials as flooring made the scenery look gorgeous, concealed the water collection system that collects rainwater, and improved drainage where people walk.

  A hollow wood deck was constructed throughout the external site of the new building, so the Braille tiles were mounted on it. Braille fences will be constructed continuously from the outside walkway to the entrance of the building, but in this building there were obstacles such as planted trees in the site, so to avoid it, Braille fences are made of multiple deck materials. Are attached so that they cross each other or parallel.

The conventional bonding method peels off quickly, and the screw fixing method crosses and attaches the screws, loosening the screws.
However, when the resin cylinder is loaded in the hollow of the deck and the epoxy adhesive is hardened, it becomes a wedge like a metal and does not peel off. In addition, the resin cylinder is a commercially available one that can be purchased cheaply, and it is easy to cut and charge, so the construction time is also shortened.
