Description

  The present invention relates to a method for constructing a staircase tile, and is applied in the field construction. When attaching a non-slip tile when tiling a tread surface, the anti-slip tile is accurately and efficiently constructed, so that the entire tile It is related with the construction method of the non-slip tile staircase tile which made it possible to perform construction of swiftly and accurately.

  Conventionally, of the finishing of each part of the staircase, the tread surface is a place where the user actually steps, and it is necessary to finish in consideration of safety aspects such as slip prevention in addition to normal walking comfort and impact resistance. In addition, for outdoor stairs, finishing materials to be used for the treads and raised parts are determined in consideration of water resistance. For example, there are stone materials, porcelain tiles, and mortar finishes as finishing materials that satisfy these required specifications in outdoor staircases, etc., but porcelain tiled stairs are widely used.

  There are various types of tiles that are produced depending on the construction site, but there are treads, flat tiles for lifting, anti-slip tiles that are constructed on the corners of the treads, etc. . For example, these tiles are pasted on the concrete frame after the on-site concrete staircase has reached a predetermined strength, and are attached to the concrete frame in accordance with the allocation using an adhesive material such as mortar. At that time, the use of a tile unit having a matching size for a floor portion such as a tread having a predetermined shape facilitates the construction.

  A generally known tile unit is intended for a small tile such as a mosaic tile, and a tile unit in which a large number of tiles are pasted on a mount with a predetermined pitch is pasted on a casing. On the other hand, as a tile unit that can use large tiles and is easy to transport, the wire mesh is replaced with a mount, and the tile is attached in advance to the wire mesh. There has been proposed a tile unit that is bonded to a thin film (see Patent Document 1).

JP-A-11-93376.

  By the way, when assembling the formwork at the staircase position and constructing the staircase structure with on-site concrete, either stick the porcelain tiles sequentially to the concrete frame surface where the predetermined strength was obtained as described above, or the dimensions of the tread The method of pasting using the combined tile unit is taken. For this reason, a tile cannot be constructed during a predetermined curing period in which sufficient strength cannot be obtained. In addition, the anti-slip tiles to be attached to the corners of the treads are the standard for positioning the tiles, and the surface has a streak-like anti-slip pattern on the surface. It is also necessary to construct with high accuracy so that the streak passes between them. Furthermore, since the anti-slip tile is the place where the pedaling force is most applied during operation, it is necessary to securely bond the tile.

  However, in the conventional tile unit, a non-slip tile that is surely adhered can only be constructed in the same manner as other flat tiles laid on the tread. And when adhesive strength, such as mortar, is not fully obtained when it is affixed to concrete, if force is applied to the non-slip tile, there is also a problem that it is easily peeled off or shifted. In addition, there is a method in which a non-slip tile is attached to a wire mesh as described above, and the tile unit is arranged at a protruding corner position. However, the tile unit disclosed in Patent Document 1 is arranged with a predetermined interval in the vertical and horizontal directions. Since it is attached to the ground surface using a cement adhesive such as mortar using a small wire diameter turtle shell wire (hexagonal mesh), etc., it is applied to the tread surface of the stairs. If a force is applied to tiles arranged at the initial stage of curing such as during work, the rigidity of the mesh is small, and the part where the force is applied is deformed to be recessed, resulting in unevenness in the tile surfaces arranged. There is a risk that. These problems also occur when the tile is applied after the concrete frame has hardened. For this reason, it is desired to perform tile construction accurately and promptly immediately after placing concrete or after hardening.

  Therefore, the object of the present invention is to solve the above-mentioned problems of the prior art so that the tile can be constructed with high accuracy and promptly in a stable state when constructing the tread surface and anti-slip tile. The purpose is to provide a method for constructing staircase tiles.

  In order to achieve the above object, the present invention provides a staircase tile construction method in which tiles are laid down on the tread surface of a concrete staircase, and a mesh body in which non-slip tiles are attached in a row to a length equal to the staircase width of the concrete staircase. It adheres to the concrete surface after hardening or just after placement along the protruding corners of each tread surface, and thereafter, a flat tile is constructed on the tread surface using a non-slip tile on the mesh as a guide.

  The mesh body is preferably a rectangular metal mesh having a long side equal to the step width, particularly an expanded metal.

  As mentioned above, in tile finishing of staircases, the tile unit composed of a mesh body with anti-slip tiles is adhered to the concrete placing surface, so that the tile construction of the tread surface of the staircase can be performed accurately and quickly. There is an effect.

Hereinafter, an embodiment of a construction method of a staircase tile according to the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a partial perspective view showing a state in which a tile unit 10 having a non-slip tile 11 attached is attached to the position of the protruding corner edge 3 of the tread surface 2 of each stairs 1 immediately after the on-site concrete is placed. is there. The tile unit 10 used in the present invention has a rectangular shape composed of a long side equal to the width of the staircase 1 and a short side approximately twice the width of the anti-slip tile 11 as shown in the front and back surfaces of FIG. The non-slip tiles 11 are attached in a row along the long edge 12a of the expanded metal 12 as a net-like body. The expanded metal 12 used in the present embodiment is a reticulated plate material obtained by known steel plate processing, and stretches the cut portion put in the steel plate so that a predetermined opening size is obtained, and the rhombic openings are continuous vertically and horizontally. It is a wire mesh that spreads out. In this embodiment, a known porcelain tile is used as the anti-slip tile 11. The anti-slip tile 11 is formed with several grooves 13 along the longitudinal direction of the surface, and the grooves are formed to slide over the width of the stairs when a plurality of anti-slip tiles 11 are arranged side by side. A stop groove 14 is formed. Further, as shown in FIG. 2B, each anti-slip tile 11 is bonded to the expanded metal 12 by a urethane resin adhesive 15. The paste-like urethane resin adhesive 15 used in the present embodiment has a low viscosity, can sufficiently adhere to the tile 11 and the mesh of the mesh body at the time of adhesion, and has an adhesive strength between the tile and the wire mesh in a relatively short time. Reach practical strength. Needless to say, epoxy adhesives, acrylic resin adhesives, and the like can be used for the adhesive used.

  The tile unit 10 is generally attached after the concrete is hardened, but may be immediately after placing the concrete. Further, the tile unit 10 is supported by a part of the reinforcing bar in advance using a legged net. It can also be installed before placing concrete.

  The tile unit 10 in which the anti-slip tiles 11 are bonded in a row to the expanded metal 12 is sequentially attached to the position 3 of the protruding corner edge (see FIG. 1) of the relatively low strength concrete tread 2. First, a mortar base 16 as an adhesive is applied to the concrete surface in a thin layer, and the expanded metal 12 with the anti-slip tile 11 is pasted on the mortar base 16 with sufficient pressing force. Subsequently, as shown in FIG. 3, the flat tile 17 having the same plane size as the anti-slip tile 11 is attached to the tread surface 2. At this time, the flat tile 17 adjacent to the anti-slip tile 11 is pasted on the net-like body, but when pasting the other flat tiles 17..., The thickness of the mortar base 16 is adjusted to adjust the entire tread 2. Make the tile surface smooth. In addition, it is preferable to stick the same kind of porcelain tiles, artificial stone panels, water-resistant resin tiles, or the like on the surface of the lift 18.

  Each figure in FIG. 4 is a plan view showing a modified example of the mesh body (expanded metal) 12. The rectangular mesh shown in FIG. 2 can also be used to securely attach the anti-slip tile 11 to the edge position 3 of the tread 2, but the mesh is not necessary to improve the workability or installation accuracy of the flat tile on the tread 2. A modification of the body will be described. FIG. 4A shows a modification in which a part of the mesh body is provided with an extension 12b in the depth length (step width) of the tread. According to this modification, immediately after the construction of the expanded metal 12 with the anti-slip tile 11, the flat tile can be constructed with high accuracy using the mesh as a guide, and the construction can be speeded up. 4 (b) to 4 (d) show modifications using a welded wire mesh 22 as the material of the mesh body. When the wire mesh is made of a material having the same wire diameter as the expanded metal 12, it is light and relatively small in rigidity, so that it is easy to handle at the time of construction, but it needs sufficient rigidity even after laying on concrete. In this case, as shown in FIGS. 4C and 4D, it is preferable to stiffen the processed rebar by welding it to the mesh. FIG. 4 (c) shows a modified example in which the mesh body is reinforced with a bent reinforcing bar 23 processed into a sawtooth shape, and FIG. 4 (d) shows that the long side of the substantially square loop bar 24 is fixed to the adhesive portion of the tile. A variation is shown.

  The metal mesh that can be used in place of the expanded metal 12 includes a welded metal mesh, various metal laths (JIS A 5505), turtle shell metal mesh, punched metal, etc., various steel plate processed products, metal mesh equivalent products, or equivalent rigidity. Resin network products having alkali resistance can also be used.

  Note that the tile unit 10 used in the present invention, in which the anti-slip tiles 11 are adhered to the net-like body, is preliminarily placed at a predetermined position along the sill plate of the formwork as a leading tile in the construction of the precast concrete stairs. It is also possible to cast concrete and attach it to a part of the finished precast concrete product. In that case, it is preferable that the flat tile is pasted in advance with a material that can withstand the precast concrete curing conditions.
