Description

  The present invention relates to a tile panel mounting structure in which a tile panel is installed on a wall surface of a building.

  Tile is one of the building materials used for finishing the walls and floors of buildings. For example, in tunnels and the like, it is necessary to create a good visual environment, so tiles are installed on the inner wall surface of the tunnel, the inner wall surface of the tunnel is brightened, the appearance is improved, and the visibility and visibility of vehicles and obstacles ahead are improved. It improves the induction effect and the lighting effect.

  Further, for example, Patent Document 1 discloses a tile panel as an improvement in workability when installing a tile. Such tile panels have a plurality of tiles affixed to the surface of the substrate, and by installing them on the base frame in units of tile panels, it is easier to install than to install tiles one by one. Convenience is improved.

  By the way, for example, the lower ground of a building such as a tunnel is not always a flat surface convenient for construction, and there may be uneven portions of various sizes. It is never easy to install tiles on such a ground surface, especially in the case of tile panels, because the area per installation unit is larger than the tile itself, the presence of irregularities makes clean installation more difficult. There's a problem.

  The present invention has been made to solve the above-described problem, and an object of the present invention is to provide a tile panel mounting structure that can perform a fine tile finish even when the installation target has a non-land portion.

  In order to achieve the above-described object, the tile panel mounting structure of the present invention maintains a tile panel having a plurality of tiles attached to a substrate on the surface, and the tile panel in a state separated from the installation target. A support member disposed between the installation target and the tile panel, a mounting member for fixing the tile panel to the installation target, and a foam provided between the back surface of the tile panel and the support member. A resin sheet.

  According to the tile panel mounting structure of the present invention, it is possible to perform a beautiful tile finish even when there is a non-land portion in the installation target.

It is a figure which shows the structure of the attachment structure of the tile panel which concerns on embodiment of this invention. It is a front view of the tile panel regarding this Embodiment. FIG. 3 is a side view of the tile panel of FIG. 2. It is a figure of the same aspect as FIG. 2 regarding another tile panel structure. It is a figure of the same aspect as FIG. 3 regarding another tile panel structure. It is a figure which expands and shows the vicinity of an attachment member. It is a figure which illustrates the other aspect regarding an attachment member. It is a figure which shows the tile panel attached to the tunnel inner wall surface which is a mounting object.

  Embodiments of a tile panel mounting structure according to the present invention will be described below with reference to the accompanying drawings. In the drawings, the same reference numerals indicate the same or corresponding parts. FIG. 1 is a diagram showing a configuration of a tile panel mounting structure according to the present embodiment. In the drawings of the present application, priority is given to visibility and ease of understanding, and depending on the target part, the thickness direction (Z direction) is shown to be considerably thicker than the actual thickness, and the rate of increase in thickness varies depending on each part. is there. The tile panel attachment structure 1 includes a tile panel 3, a support member 5, an attachment member 7, and a foamed resin sheet 9. The tile panel 3 is indicated by a symbol W in FIG. 1 and has a plurality of tiles 12 and 13 attached to the substrate 11 on the surface.

  Details of the tile panel will be described with reference to FIGS. FIG. 2 is a front view of the tile panel according to the present embodiment, and FIG. 3 is a side view thereof. As shown in FIGS. 2 and 3, in the tile panel 3, a plurality of reference tiles 12 and accessory tiles 13 are fixed to one side of a flat substrate 11 in a vertical and horizontal manner by an adhesive 14. . 2 and 3, the tile without hatching is the reference tile 12, and the tile with hatching hatching indicates the accessory tile 13. In the illustrated example, the reference tile 12 and the accessory tile 13 are arranged in a row in which four tiles are attached in parallel in the X direction, with nine rows in the Y direction, and alternate tiles every two rows in the Y direction. Is attached, and only one row of reference tiles 12 is attached in one row below the Y direction.

  If the substrate 11 is attached along a curved surface such as a tunnel inner wall surface, a highly tough board that can be bent along the curved surface is preferable. For example, a flat plate shape such as a fiber-reinforced cement plate or a calcium silicate plate is used. The ceramic board is suitable. In particular, when a highly tough board having a bending strength of 30 N / mm 2 or more and a bending kinematic elastic coefficient of about 10 to 15 kN / mm 2 is used, it can be bent well along the curved surface of the inner wall surface of the tunnel. Such a highly tough board uses, for example, hydraulic cement as a matrix raw material, cellulose pulp and vinylon fiber as a fiber raw material, and fillers used as necessary (acicular wollastonite powder, mica powder) , Calcium carbonate powder, etc.) and the like, and can be manufactured by wet-mixing and making paper, and curing and curing after pressing. When such a high toughness board is used as the substrate 11, the thickness is preferably about 3 mm to 6 mm, is lightweight, and has an advantage that there is no risk of corrosion because it is inorganic.

  The reference tile 12 is typically a ceramic tile, and the surface of the ceramic tile can be improved by applying a glaze to the surface of the tile. Among them, exterior tiles of JIS A 5209 “Ceramic Ceramic Tile” are usually used for tile panels intended for tunnel applications. Usually, a square having a side of about 45 mm to 235 mm and a thickness of about 5 mm to 10 mm is used.

  The accessory tile 13 is a tile made of the same material as that of the reference tile 12, and is a tile having a notch portion 15 formed by notching a corner portion that forms a joint portion between the accessory tiles 13. The notch may be formed in a straight line, for example, in a curved line so as to form an arc. When illustrating the joint width between the tiles in the tile panel, the interval between the vertical joints (vertical joints) is usually 0 mm (butting) to 5 mm, and the interval between the horizontal joints (horizontal joints) is usually 1 mm to 10 mm. In the case where the foundation frame to be installed is a curved surface such as a tunnel, the horizontal joint interval needs to be at least 1 mm. This is because the tile is hard and the panel cannot be constructed along the curved surface. Further, the accessory tile 13 is provided with a notch 15, whereby a substrate exposed portion 16 is formed in the substrate 11 where the substrate 11 is exposed in a substantially rhombus shape at the intersection of joints. In the present embodiment, the substrate 11 has a perforation 17 that is a pilot hole through which a bolt, which will be described later, passes, in the substrate exposed portion 16. The perforations 17 are preferably provided at four or more locations on the tile panel, and the interval between them is appropriate. In the present embodiment, the tile panel 3 is provided with a total of four perforations 17 with a half perforation 17 on the side of the tile panel 3 at 401 mm intervals. The diameter of the perforations 17 may be any diameter that allows penetration of bolts described later. The perforation may be performed in advance, but may be perforated when the panel is attached.

  The adhesive 14 is not particularly limited, but an adhesive excellent in water resistance is preferable. For example, adhesives such as epoxy, elastic epoxy, modified silicone, polyurethane, and urethane that are less susceptible to strength deterioration due to moisture ingress during tile cleaning and the like are suitable.

  As shown in FIGS. 2 and 3, the tile panel 3 has a configuration (first tile panel configuration) in which substrate protrusions 18 </ b> A are provided on both the uppermost and lowermost sides in the Y direction. As another variation regarding the tile panel 3, the following configuration may be used. 4 and 5 are a front view and a side view of a tile panel as another variation. In the tile panel 3, the reference tile 12 attached to the top in the Y direction is a predetermined length longer than the substrate 11. FIG. A step 18B formed by a tile protrusion fixed in a protruding state, and a substrate protrusion in which the substrate 11 protrudes downward by a predetermined length from the lower side of the reference tile 12 attached to the lowermost part in the Y direction. You may have the structure (2nd tile panel structure) which has the part 18A. Further, as another variation, although not shown in the drawings, the tile panel 3 is provided with a substrate protrusion 18A on the uppermost or lowermost side in the Y direction, and on the other end, the tile side and the substrate side are provided. You may have the structure (3rd tile panel structure) made to correspond. In the present embodiment, the first tile panel configuration is used. In the case of the second tile panel configuration, the length that the reference tile 12 of the step portion 18B protrudes and the length that the substrate 11 of the substrate protrusion portion 18A protrudes are the length that the reference tile 12 of the step portion 18B protrudes. Accordingly, the length of the protruding portion of the substrate protruding portion 18A is appropriately set so as to be longer. This is because, when the tile panels 3 are installed in parallel in the Y direction, the board protruding portion 18A of the separate tile panel 3 is combined with the step portion 18B of the tile panel 3 so as to be in a so-called consensus state. The tile panels 3 can be easily installed in parallel.

  Further, the portion without tiles formed between the tiles is a joint portion, and the joint width and the size of each tile are appropriately set according to the cross-sectional radius of the tunnel wall surface to be constructed within the range of the above conditions. . The tile panel 3 in the present embodiment uses a high toughness board (fiber reinforced cement board) manufactured by a papermaking method as a substrate so that the papermaking direction of the substrate is the vertical direction of the tile panel. The dimensions of the substrate were 902 mm in length, 802 mm in width, 4 mm in thickness, the dimensions of the tile were 98 mm x 198 mm x 6.8 mm in thickness, and the joint width between the tiles was 2 mm for both the vertical joint and the horizontal joint. In addition, a 2 mm board protrusion 18A was provided at both the uppermost and lowermost positions in the Y direction of the tile panel, and a 2 mm board protrusion was provided at each end in the X direction. The size of the tile panel is a panel having a length of 902 mm, a width of 802 mm, and a thickness of 11.3 mm. In addition, joints, joint coking, and the like may be applied to the joints of the tile panel 3 as necessary.

  In the present embodiment, the above-described tile panel 3 shown in FIGS. 2 and 3 is used. However, the present invention is not limited to this, and tile panels having other configurations are used. It is also possible to implement.

  Returning to FIG. 1, the support member 5 is arranged between the installation target 2 and the tile panel 3 so as to keep the tile panel 3 away from the installation target (base frame) 2. The support member 5 can be made of a ceramic material or a metal material. In the present embodiment, the support member 5 is made of the same system of fiber reinforced cement as the substrate 11 of the tile panel 3. The thickness of the support member 5 is preferably 3 mm to 100 mm and about 4 mm to 15 mm.

  FIG. 6 is an enlarged view showing the vicinity of the attachment member. The attachment member 7 is for fixing the tile panel 3 to the installation target 2, and includes a bolt 24, an anchor 26, a washer 31, and a nut 32 as shown in FIGS. 1 and 6. The bolt 24 is a bolt having a male screw structure that can be screwed into the anchor 26, and is an all screw bolt that does not have a pan head and can be inserted into the diameter of the hole 17 of the tile panel 3. The bolt 24 is a bolt for locking the tile panel 3, and fixes the tile panel 3 to the reference plane by attaching and tightening the nut 32. The anchor 26 has a female screw structure into which the bolt 24 is screwed, and is an internal cone driving type that is fixed to the so-called installation target 2. It should be noted that any method for placing the anchor 26 on the installation target 2 may be used, and since it is a well-known technique, description thereof is omitted. Further, if the tile panel can be fixed to the installation target, the mode of the mounting member is not particularly limited. If another mode is exemplified, the washer 31 and the nut 32 are notched 15 as shown in FIG. It may be a mode that fits within.

  The foamed resin sheet 9 covers the entire back surface of the tile panel 3, and is provided between the back surface of the tile panel 3 and the support member 5. As a more preferable example, the foamed resin sheet 9 may include an aluminum layer on one or both of the front surface (surface on the substrate 11 side) and the back surface (surface on the installation target 2 side). Good. In particular, when the aluminum layer is provided on the back surface of the foamed resin sheet 9, the aluminum layer functions as a moisture-proof layer, and there is an advantage that moisture, dirt, and the like hardly adhere to the back surface.

  A specific example of the foamed resin sheet 9 is Miramat (registered trademark), which is a highly foamed polyethylene sheet manufactured by JSP Corporation. This highly foamed polyethylene sheet has an aluminum layer only on one side. Moreover, as an installation aspect, it arrange | positions so that an aluminum layer may be located in the back surface (surface by the side of the installation object 2) in a highly foamed polyethylene sheet.

  The thickness of the foamed resin sheet 9 is preferably about 0.5 mm to 2 mm. If the thickness of the foamed resin sheet 9 is 4 mm or more, it takes a long time to adjust the bolt tightening level when the tile panel is attached, which is negative in terms of workability.

  Next, the construction method of the tile panel in this Embodiment is demonstrated.

  FIG. 8 is a diagram showing an inner wall surface of a tunnel, which is an installation target of a tile panel. As an example, the enforcement procedure described below is to attach a tile panel to the inner wall surface of the tunnel where all tiles that have already been constructed are peeled off.

  It is assumed that the tunnel inner wall surface, which is the installation target 2, has old tiles that have already been removed and has unevenness. In addition, it is assumed that the area where the old tiles are peeled off on the inner wall surface of the tunnel is exposed by exposing the tunnel base frame itself.

  A case will be described in which the tile panel 3 described above is attached to a region where the base casing itself is exposed. First, the support member 5 is attached to the inner wall surface of the tunnel (tunnel base frame). The attachment method is as follows. The supporting member 5 is placed at a predetermined position on the inner wall surface of the tunnel, the base member of the tunnel is drilled from several places on the supporting member 5, anchors 25 are respectively placed, and each anchor 25 is placed. Then, bolts (not shown) are sequentially screwed, the bolts are erected, then a washer (not shown) is passed through the bolts, and then nuts (not shown) are screwed onto the bolts. Thus, the support member 5 is fixed to the inner wall surface of the tunnel. At this time, it is preferable that the surface of the support member 5 is countersunk so that the nut is accommodated in the counterbore so that the screwed nut does not protrude from the surface of the support member 5. The interval between the support members 5 is the interval between the perforations 17 (substrate exposed portions) of the tile panel 3, and in this embodiment, the distance between the center lines of the adjacent support members 5 is the perforation of the tile panel 3 described above. It shall be installed so that it may become the space | interval substantially the same as the space | interval of 17.

  Next, the foamed resin sheet 9 and the tile panel 3 are arranged on the support member 5 fixed as described above. In addition, the arrangement of the foamed resin sheet 9 may be such that only the foamed resin sheet 9 is first arranged outside the support member 5 separately from the tile panel 3, or the foamed resin sheet 9 is arranged in advance on the side of the substrate 11 of the tile panel 3. The tile panel 3 and the foamed resin sheet 9 may be disposed outside the support member 5 together.

  If the foamed resin sheet 9 and the tile panel 3 are arranged outside the support member 5, the foamed resin sheet 9 and the support member 5 are formed from the respective perforations 17 of the tile panel 3 (or on the substrate exposed portion of the tile panel 3). The anchors 26 are pierced through the tunnels, the anchors 26 are driven, the bolts 24 are sequentially screwed into the anchors 26, and the bolts 24 are erected. Subsequently, the tile panel 3 and the foamed resin sheet 9 are fixed to the inner wall surface of the tunnel by passing a washer 31 to each bolt 24 protruding from the substrate 11 of the tile panel 3 and then screwing a nut 32 to the bolt 24. To do. Since both the anchor 26 for fixing the tile panel 3 and the like and the anchor 25 for fixing the support member 5 pass through the support member 5, the placement positions of both anchors are set so as not to overlap. I will do it.

  In this embodiment, the installation target 2 is not referred to as a curved surface. However, even in the case of a curved surface, the tile panel 3 has a highly tough substrate 11 and joints between the tiles. Therefore, it goes without saying that the curved surface shape of the installation target can be satisfactorily followed and fixed.

  According to the tile panel mounting structure according to the present embodiment described above, even if there is a non-land portion in the installation target, by installing the tile panel in a state of floating from the installation target, The tile panel can be installed neatly.

In addition, according to the inventor's study, in the installation target such as the inner wall surface of the tunnel, for example, moisture may ooze out from the tunnel rock, in which case the oozed water wraps around the tile surface side, There is a problem that the tile surface is soiled and the visibility and aesthetics in the tunnel are impaired. In addition, when the tile panel is fixed in a state of floating from the inner wall surface of the tunnel, a high humidity atmosphere exists in the space between the tile panel and the inner wall surface of the tunnel, coupled with the above-mentioned problem of moisture exudation. Therefore, depending on individual circumstances, condensation may occur on the surface of the tile panel on the installation target side. In particular, when the condensed moisture repeatedly freezes and thaws , there may be a problem that the tile panel substrate is damaged. Against such problems, the tile panel mounting structure according to the present embodiment includes a foamed resin sheet on the surface (back surface) of the tile panel on the installation target side. It is possible to suppress a large temperature difference on the back surface. For this reason, it has become possible to significantly reduce the occurrence of condensation on the back surface of the tile panel while maintaining the tile panel in a state of floating from the installation target. Furthermore, even if small-scale condensation occurs on the back surface of the tile panel, if the foamed resin sheet has an aluminum layer in the tile panel mounting structure according to the present embodiment, the tile panel substrate deteriorates. Can be more reliably prevented.

  Although the contents of the present invention have been specifically described with reference to the preferred embodiments, various modifications can be made by those skilled in the art based on the basic technical idea and teachings of the present invention. It is self-explanatory.
