Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a juxtaposition clamping device for non-slip tiles that is attached to the end of the treads of concrete stairs.

(Conventional technology) The conventional work procedure for pasting non-slip onto stair treads is to first place mortar on the edge of the stair tread, then check the horizontality by visual inspection and ink the left and right sides of the stair. The non-slip tiles were arranged one by one according to the pattern, and the joints between the tiles were filled at a later date.

(Problems to be solved by the invention) However, in the conventional construction method described above, when pasting non-slip tiles, the work is done visually while checking the horizontality of each tile, which takes time. In addition, since the tile joints must be filled at a later date, if the treads and risers are finished while the joints are not filled, there is a problem that the tiles will easily peel or crack. was.

(Means for Solving the Problems) The present invention was developed as a result of various studies to solve the above problems, and was developed by holding several (for example, 5) non-slip tiles at the same time using a holding plate whose spacing can be adjusted using screws. In addition to filling the joints, the mortar can be pasted all at once to the stairs while holding it in place and checking its level with a spirit level.

The present invention will be described below with reference to the drawings. Reference numeral 1 denotes a parallel tile surface in which the left and right side surfaces are bent along the longitudinal direction into an L-shaped vertical section to form screw rod bearing surfaces 2, 2. Reference numeral 3 denotes a tile holding substrate formed on the outer side surface of the tile parallel surface 1 so as to have a substantially T-shaped longitudinal section along the longitudinal direction. Reference numeral 4 denotes a rubber plate attached to the inner surface of the tile holding substrate 3 in the longitudinal direction. Reference numeral 5 denotes an opening/closing clamping surface 6 formed on the outside of the inner (left side in FIG. 1) screw rod bearing surface 2, facing the tile clamping substrate 3 and parallel to the longitudinal direction, with an inverted L-shape in vertical section. It is an opening/closing clamp plate. Reference numeral 7 denotes a rubber plate attached to the inner surface of the opening/closing clamping surface 6 in the longitudinal direction. Reference numerals 8 and 8 denote opening/closing screws inserted from the tile holding board 3 side toward the opening/closing holding plate 5 side in a direction perpendicular to the tile holding board 3, and a knob 9 is provided at one end of each screw. 10 is a level provided at the center of the tile parallel surface 1.

(Function) The present invention was carried out, and as shown in FIG. 3, the product of the present invention was turned over and the non-slip tiles A were arranged horizontally in a row on the tile parallel surface 1 with the front side facing down. When the knob 9 is rotated, the opening/closing clamping surface 6 moves under the action of the opening/closing screw 8, and the gap between it and the tile clamping board 3 opens and closes, so that the side surface of each tile is attached to the rubber plate 7,
Step 4 allows you to firmly clamp the tiles, and in this state, fill the joints between the tiles (spaddle the joints), and with the tiles in this state, level the mortar. Place the non-slip tile on the part of the staircase where the mortar is placed to coat and dig into the tile. Hold the tile with both hands with the tile facing down, and while checking the level with a spirit level, line the finish ink on the left and right sides of the staircase. Place the group of tiles that are still being held in place and fix them on the mortar. After fixing is completed, several non-slip tiles can be attached at the same time by simply loosening and removing the opening/closing screw 8 of the present invention.

(Example) The opening/closing clamping plate 5 is not limited to an L-shaped longitudinal section, but substantially the same effect can be expected as long as it has the opening/closing clamping surface 6.

(Effects of the invention) When this invention is implemented, it becomes unnecessary to check the level of each individual non-slip tile when pasting non-slip tiles to the end of the treads of stairs, and Several tiles can be held at the same level horizontally by simply placing them, and the horizontal sides can also be held in a straight line by the tile holding board 3. At this point, the joints are filled with a ladle. It is possible to confirm the level at the same time with a spirit level while firmly clamping and fixing the product, making it quick and easy to check the level. In this state, it is possible to place and paste on the mortar, increasing work efficiency. It has improved significantly, and the joint filling between each tile has also been completed, and with the tiles fixed in parallel, the tread finish can be improved later.
Since finishing work on the riser surface can be done, this design has the effect of eliminating any peeling or damage of the attached tiles.
