Description

The present invention relates to a tile construction method and roof structure.

BACKGROUND OF THE INVENTION Finishing the roof structure of houses with tiles has been a well-known technique since ancient times. In recent years, cement tiles made of hardened cement or mortar, and slate tiles made of cement mixed with fiber materials, have been used instead of the traditional tiles made of molded and fired clay. These cement tiles are thinner and lighter than conventional clay tiles, making them suitable for mass production. Reducing the weight of tiles has the advantage of reducing the load on building structures, including roofs, and making it easier to strengthen earthquake resistance.

An example of such a cement-based roof tile is shown in the plan view of FIG. The tile 91 shown in this figure is a flat tile that has a plate shape as a whole, and includes a tile main body 92 that is rectangular in plan view, and a tile that extends from the top surface of the tile main body 92 along one side edge of the tile main body 92. It also includes a step connecting portion 93 formed one step lower. As shown in FIG. 12, these roof tiles 91 are arranged by stacking tiles 91 that are adjacent to each other in the left and right direction at the step connecting portion 93, thereby connecting the roof tiles in the left and right direction so that their top surfaces are on the same plane. At the same time, tiles placed in the front and rear directions are arranged so that the front ends of the tiles 91 placed in the front row are partially overlapped with the front ends of the tiles 91 placed in the front row, so that the tiles are adjacent to each other in the front and back directions. The roof tiles are connected with each other in a stepped structure to prevent rainwater from seeping into the interior.

This type of roof tile 91 generally has a plurality of through holes 94 and 95 opened in advance, as shown in the plan view of FIG. The tool 99 is fixed at a fixed position by being fixed to a base provided on the surface that will become the roof of the building. The tile shown in FIG. 11 has through holes 94 and 95 in the center of a step connecting portion 93 provided on the side edge and on both sides of the rear end of the tile main body 92 on the ridge side.

The tiles 91 having this structure are arranged in the back row by, for example, a construction method in which a connecting tool 99 is inserted into the through holes 94 at the positions indicated by A and B at the rear end of the tile main body 92 shown in FIG. 11 and fixed. The tiles 91 can be fixed to the base. In this case, since the connectors can be arranged in a horizontal row, the number of horizontal bars to be arranged in advance can be reduced when the base for fixing the connectors is a horizontal bar. However, in this structure, the distance (L1) between the position where the tile 91 is fixed to the base with the connector 99 and the front edge 91A of the tile 91 becomes large, so the front end side of the tile in the back row is placed on the top surface of the tile in the front row. There is a problem in that the pressing force becomes smaller and wind, rainwater, etc. easily enter through this boundary.

On the other hand, a connector 99 is inserted and fixed into the through hole 94 at the position indicated by A in the rear end of the tile main body 91 shown in FIG. Depending on the construction method, the tiles 91 placed in the back row can be fixed to the base. In this case, since the two connectors 99 for fixing one tile 91 are disposed approximately in the diagonal direction of the tile 91, the position where the tile 91 is fixed to the base by the connector 99 and The distance (L2) from the front end edge 91A can be shortened. For this reason, it is possible to increase the force with which the front end of the tiles in the rear row is pressed against the top surface of the tiles in the front row, thereby effectively preventing wind, rainwater, etc. from entering through the boundary portion. However, according to this structure, as shown in FIG. Since it is necessary to arrange horizontal bars 98B for fixing the connectors 99, there is a problem in that construction of the base 98 requires time and cost.

Here, as a base for fixing tiles, flat plates such as roofing boards may be laid on the surface that will form the roof. In this case, it is also possible to omit the horizontal beam for fixing the connector that is inserted through the through hole of the step connector, and to directly fix this connector to the roof board. However, according to this structure, the connector that is inserted through the step connection part is fixed to the roofing board while the front end of the rear row of tiles overlaps the rear end of the front row of tiles, so the lower surface of the step connection and the roofing board are fixed. A gap is created between the two and the step connecting part cannot be firmly fixed to the base. Therefore, in order to firmly fix the connector that is inserted through the step connection part to the base, it is preferable to place a member such as a horizontal bar at the position of the through hole of the step connection part, which saves time and cost in the construction of the base. There were such problems.

In addition, in conventional construction methods, at least two connectors are used to secure each tile, so as the number of tiles increases, the amount of work required to insert connectors into each through hole and secure the tiles increases. There were problems in that the work of fixing tiles was time-consuming and the number of parts increased, increasing construction costs.

Japanese Patent Application Publication No. 2007-009655

The present invention has been made in view of this background, and one of its objectives is to reduce construction costs while efficiently fixing roof tiles, and to securely and securely secure tiles that are stacked on top of each other. An object of the present invention is to provide a roof structure and a construction method for tiles that can be firmly connected.

Means for solving the problem and effects of the invention

According to the tile construction method according to the first aspect of the present invention, a plurality of tiles are installed on a surface constituting the roof of a building in a state in which they are connected to each other in the front, back, left and right directions. The eaves are rectangular in plan view and have a front edge of the eave side and a rear edge of the ridge side facing each other in the front and back, and both side edges facing left and right, and have an opening on the front edge side of the eave side of one side edge. A tile preparation process of preparing a plurality of tiles each having a side through-hole and a ridge-side through-hole opened at the rear end of the ridge; The method includes a roofing process in which a plurality of tiles are arranged in a plurality of rows from the eaves side to the ridge side, and the tiles are connected in the left and right direction to form rows, and the roof is covered with tiles. In the roofing process, the ridge-side through-hole of the tile placed on the eave side is coaxial with the eave-side through-hole of the tile placed on the ridge side. A front and back lamination process in which the front end of the eave side of the tile placed on the ridge side is placed over the edge, and a connector is installed between the eave side through hole and the ridge side through hole which are coaxially arranged in the front and back lamination process. and fixing a connector passing through the ridge side through hole and the eaves side through hole to the base.

According to the above construction method, tiles that are adjacent to each other in the front and back direction are fixed to the base via a connector that penetrates the laminated portion of each other, so two adjacent tiles can be fixed at the same time by fixing in one place, which is different from the conventional method. Compared to the previous construction method, the number of locations for fixing tiles can be halved, saving labor for fixing tiles, shortening the construction period, and providing the excellent advantage of reducing construction costs.

According to the tile construction method according to the second aspect of the present invention, the distance (d) between the eave side through hole opened in one side edge of the tile and the front edge of the eave side is The lap width (S) between the ridge-side rear end of the tile placed on the eave side and the eave-side front end of the tile placed on the ridge side.

According to the above construction method, the connecting tool is inserted into the eave-side through-hole provided on the eaves side so that the distance between the tiles on the eave side is shorter than the stacked width of the tiles stacked on the ridge side. Since the roof tiles are fixed to the base, tiles stacked on top of each other can be reliably fixed to the base at the laminated portions. Therefore, the roof tiles stacked above can withstand strong wind pressure and will not easily come off even when exposed to strong winds.

According to the tile construction method according to the third aspect of the present invention, the distance (d) between the eave side through hole and the front edge of the eave side is set to 40% or less of the total length (D) of the tile in the front-rear direction.

According to the above construction method, the position of the eave side through hole that opens in the tile is on the front edge of the eave side, and is at a position that is 40% or less of the total length (D) in the front and back direction of the tile. By fixing the front end portion of the roof tile close to the front edge of the eave side to the base, it is possible to effectively prevent the upper tile from coming off due to strong winds.

According to the tile construction method according to the fourth aspect of the present invention, the ridge side through-holes of the tile are placed at positions where the tiles placed on the ridge side are arranged in a staggered manner with respect to the tiles placed on the eaves side. It's open.

According to the above construction method, the ridge side through-holes are provided in positions where the tiles placed on the ridge side are arranged in a staggered manner relative to the tiles placed on the eave side, so To easily and accurately lay a plurality of tiles arranged in a plurality of rows in a staggered manner to create a beautiful appearance.

According to the tile construction method according to the fifth aspect of the present invention, the base provided in advance on the surface constituting the roof of the building is arranged in a plurality of rows extending in the left-right direction at predetermined intervals and parallel to each other. In the front and rear lamination process, the ridge-side through-hole of the tile placed on the eave side and the eave-side through-hole of the tile placed on the ridge side are arranged coaxially on the horizontal cross-piece. Each tile is supported by two rows of horizontal bars, front and back.

According to the above construction method, multiple rows of horizontal bars extended in the left and right direction in parallel positions are used as the base for fixing the tiles, which simplifies the base structure and allows multiple tiles to be installed at low cost. It can be installed on the roof.

According to the tile construction method according to the sixth aspect of the present invention, the tile prepared in the tile preparation step has a plurality of ridge-side through holes opened along the ridge-side rear edge, and In the lamination process, a plurality of ridge-side through holes of tiles arranged on the eaves side are selected, and the eave-side through holes of the tiles arranged on the ridge side are arranged coaxially.

According to the above construction method, when the front end of the ridge side tile is overlapped with the ridge side rear end of the tile placed on the eave side, the eave side through hole of the ridge side tile is arranged. By selecting the holes, the tiles on the ridge side can be placed in the optimal position relative to the tiles on the eave side. Thereby, by changing the ridge-side through-hole that is aligned with the eave-side through-hole, it is possible to change the connection position in the left-right direction between tiles that are adjacent to each other in the front and back. As a result, the width of the tile roof structure can be changed depending on the shape and size of the roof of the building. It is also possible to adjust the area where tiles are overlapped depending on the required specifications such as the size, strength, and water resistance of the roof of the building.

According to the tile construction method according to the seventh aspect of the present invention, the tile prepared in the tile preparation step has a tile body portion that is rectangular in plan view, and a side edge of the tile body portion that is rectangular in plan view. and a step connecting part formed one step lower than the top surface of the roof, and an eave side through hole is opened in the step connecting part, and in the roofing process, adjacent tiles on the left and right are stacked on each other at the step connecting part. and connect.

According to the above construction method, an eave-side through hole is provided in the step connection part formed low on one side edge of the tile main body, which is rectangular in plan view, and tiles that are adjacent to each other on the left and right are stacked at this step connection part. Since the connecting tool is inserted through the eave side through-hole, it can be covered and hidden by the roof tile stacked on top of the step connecting part. Therefore, the appearance of the boundary between the left and right roof tiles can be made beautiful, and rainwater or the like can be effectively prevented from entering through the boundary.

According to the tile construction method according to the eighth aspect of the present invention, in the roofing process, the tiles arranged in a stacked state in front and behind each other are inserted through the eave side through hole and the ridge side through hole. It is fixed to the substrate through only one connector.

The construction method described above has the advantage that construction can be carried out efficiently while minimizing the number of connectors used. In particular, for tiles placed in rows other than the row closest to the eaves and the row closest to the ridge, only one connector is used per tile, reducing the labor and cost of construction. Can be constructed.

A roof structure according to an embodiment of the present invention is a roof structure in which a plurality of roof tiles are installed and fixed in a state in which they are connected from front to back and left to right on a surface that constitutes the roof of a building. The tile has a rectangular shape in plan view having a front edge of the eave side and a rear edge of the ridge side facing each other in the front and back, and both side edges facing left and right, and has an opening on the front edge of the eave side of one side edge. It has an eave side through hole and a ridge side through hole opened at the rear end of the ridge side.

Embodiments of the present invention will be described below based on the drawings. However, the embodiment shown below is an illustration for embodying the technical idea of the present invention, and the present invention is not limited to the following method and structure. Moreover, this specification does not in any way specify the members shown in the claims to the members of the embodiments. In particular, the dimensions, materials, shapes, relative positions, etc. of the components described in the embodiments are not intended to limit the scope of the present invention, unless otherwise specified, and are merely illustrative. Just an example. Note that the sizes, positional relationships, etc. of members shown in each drawing may be exaggerated for clarity of explanation. Furthermore, in the following description, the same names and symbols indicate the same or homogeneous members, and detailed descriptions will be omitted as appropriate. Furthermore, each element constituting the present invention may be configured so that a plurality of elements are made of the same member so that one member serves as a plurality of elements, or conversely, the function of one member may be performed by a plurality of members. It can also be accomplished by sharing.

The tile construction method of the present invention is a method in which a plurality of tiles are installed on a surface forming the roof of a building in a state in which they are connected to each other in the front, back, right and left directions. This construction method includes a tile preparation process of preparing a plurality of tiles, and a roofing process of covering a roof with a plurality of tiles.

[Tile preparation process]
In the tile preparation step, a plurality of tiles 1 formed into a predetermined shape are prepared. As shown in the perspective view of FIG. 1 and the plan view of FIG. 2, this tile 1 is a flat surface having a front edge 11 on the eave side and a rear edge 12 on the ridge side facing each other in the front and back, and both side edges 13 facing left and right. It has a rectangular shape when viewed, and has an eave side through hole 6 opened on the eave side front edge 11 side of one side edge, and a ridge side through hole 7 opened on the ridge side rear end 5. . An example of the roof tile 1 having this structure will be described in detail below.
In addition, in this specification, the front, back, left, and right directions of the roof tile are determined based on FIG. 2. That is, the lower direction in FIG. 2 is the front direction of the tile, the upper direction is the back direction of the tile, and the left-right direction in FIG. 2 is the left-right direction of the tile.

(tile 1)
The tile 1 shown in FIGS. 1 and 2 is a flat tile 1A whose overall shape is a flat plate. The flat tile 1A shown in the figure is a slate tile manufactured into a plate shape by press-molding mortar containing cement and fine aggregate, and has a paint film applied to its surface. Sand and fly ash are used as fine aggregate to be mixed with cement. However, it is also possible to use only sand as the fine aggregate without adding fly ash. Furthermore, preferably, in addition to fine aggregate, lightweight aggregate can also be added to the mortar. The tile 1 formed by adding lightweight aggregate has the advantage that it can be made more lightweight, has improved thermal conductivity, and can effectively prevent cracking when frozen. The lightweight aggregate used is plastic foamed into a spherical shape, or inorganic material foamed and sintered into a spherical shape. Furthermore, reinforcing fibers are preferably added to the mortar for forming the roof tile 1. For example, vinylon fiber or alkali-resistant glass fiber is used as the reinforcing fiber added to the mortar. In this way, by adding reinforcing fibers, the strength of the roof tile 1 can be increased. The thickness of the coating applied to the surface is preferably about 100 μm. However, the coating film can also have a thickness of 30 to 200 μm.

Furthermore, the roof tile 1 is not limited to a slate roof tile, and may be formed of various materials. For example, roof tiles may be made by firing a material such as clay molded into the shape of a roof tile, or may be a resin roof tile made by molding a synthetic resin such as polyvinyl chloride into a predetermined shape. Alternatively, a metal tile can be made by cutting a metal plate into a predetermined shape.

The tile 1 shown in FIGS. 1 to 5 includes a tile main body 2 having a rectangular shape in plan view, and one side edge 28 (the left edge in the figure) of the tile main body 2 on the other side of the tile main body 2. It is provided with a stepped connecting portion 3 formed one step lower than the upper surface 2A of the edge 13 (the right edge in the figure). Since the tile 1 shown in the figure is a flat tile 1A, a step connecting part 3 formed one step lower is integrally formed on one side edge 28 of the tile main body 2 whose upper surface 2A is flat. It is set up.

(Tile body part 2)
The tile main body 2 shown in FIGS. 3 to 5 has a plate shape with a flat upper surface 2A, and the tip of the eave side front end 4 is bent downward to form a laminated protruding strip 14. As shown in FIG. 6, the laminated protruding strips 14 are formed when the eave side front end 4 of the tile 1 placed on the ridge side is stacked on the ridge side rear end 5 of the tile 1 placed on the eave side. , is a portion placed on the upper surface 2A of the tile 1 placed on the eaves side. In this way, by bending the tip of the eave side front end 4 downward to form the laminated protruding strip 14, and by bringing the lower end surface of this laminated protruding strip 14 into contact with the upper surface 2A of the tile 1, It is possible to effectively prevent wind, rainwater, etc. from entering the interior from the boundaries between tiles 1. The laminated protruding strip 14 shown in FIG. 3 has an outer surface that is a vertical surface, and an inner surface that is a tapered surface that gradually becomes thicker upward. Furthermore, the tile main body part 2 shown in FIGS. 3 and 4 is provided with an inclined part 2C at the front end of the upper surface 2A. In the illustrated inclined portion 2C, the front edge of the upper surface 2A of the tile main body portion 2 is chamfered to form a downwardly inclined inclined surface. However, the roof tile 1 does not necessarily have to have an inclined part on the eaves side front end 4, and the front edge of the upper surface can be a right-angled corner part or a curved surface.

Further, the tile main body 2 shown in FIGS. 1 to 5 is provided with a waterstop ridge 15 along the rear edge in order to prevent rainwater blown up from below by the wind from entering. The water stop protrusion 15 is located closer to the eaves than the rear edge 12 on the ridge side, and is provided so as to extend to both sides of the tile main body part 2. As shown in FIG. 3, the water stop protrusion 15 has a trapezoidal cross-sectional shape whose width becomes gradually narrower toward the upper end surface, and the corners of the water stop protrusion 15 are made obtuse angles to prevent contact and collision. This makes it less susceptible to damage.

Further, the tile main body 2 is provided with a rear end protrusion 16 that protrudes rearward on the rear end side of the waterstop protrusion 15, and this rear end protrusion 16 has a positioning portion that protrudes downward. A protrusion 17 is provided. This positioning protrusion 17 is provided in order to arrange the tile 1 at a predetermined position and in a predetermined attitude when the tile 1 is placed on a base 30 provided on a roof. For example, when the base is a flat plate such as a field board, the height of the rear end 5 on the ridge side of the tile 1 can be made equal by bringing the lower end of the positioning protrusion 17 into contact with the surface of the field board. . In addition, as shown in FIG. 6, when the base 30 is a horizontal crosspiece 31 extending in the left-right direction, the positioning protrusion is By locking the tile 17 to the rear end surface of the horizontal beam 31, the tile 1 can be prevented from sliding toward the eaves. With this structure, when the roof of a building has a steep slope, it can be installed safely while placing the tiles in a fixed position.

However, the tile 1 does not necessarily have to be arranged with respect to the base 30, which is the horizontal crosspiece 31, in such a manner that the positioning protrusion 17 that protrudes downward from the rear end protrusion 16 is locked to the rear end surface of the horizontal crosspiece 31. Alternatively, as shown in FIG. 7, the lower end of the positioning protrusion 17 may be placed in contact with the upper surface of the horizontal bar 31 and fixed to the horizontal bar 31. The horizontal beam 31 shown in FIG. 7 is made by bending a metal plate so that the cross-sectional shape is a rectangular shape with a convex center, and the upper surface of the convex portion that is convex in the center serves as a mounting surface 31b on which tiles are placed. . The structure in which the roof tiles 1 are placed on the flat mounting surface 31b as described above has the advantage that the roof tiles 1 connected and arranged in the left-right direction can be arranged in a straight line accurately. In particular, the horizontal beams 31 can be arranged accurately in a straight line without being affected by warpage or deformation. This structure can be suitably used for roofs with a gentle slope.

The positioning protrusion 17 shown in FIG. 5 has a plurality of notches 17A in the center, and the tile 1 can be easily lifted up by inserting a fingertip or the like into the notch. Further, the rear end protrusion 16 is provided with a vertical rib 18 that projects upward corresponding to the position where the notch 17A of the positioning protrusion 17 is provided, and the rear end has a thinner thickness due to the notch 17A. The protrusion 16 is reinforced. In the tile 1 shown in the figure, the vertical ribs 18 are integrally formed from the water stop protrusion 15 toward the rear, so that the upper end surface of the vertical rib 18 and the upper end surface of the water stop protrusion 15 are on the same plane. .

Furthermore, the tile main body part 2 shown in the figure is provided with a plurality of rows of vertical grooves 19 extending in the front-rear direction in the central part. The tile main body 2 shown in the figure is provided with two rows of vertical grooves 19 at positions that are approximately divided into three in the width direction. Each longitudinal groove 19 is provided in an area excluding the rear end of the tile main body 2, and in an area excluding the laminated area where the front eaves side ends 4 of the tiles 1 arranged in the rear row are laminated. The tile 1 having the vertical grooves 19 at this position has the advantage that it can be easily cut along the vertical grooves 19 when cutting and dividing the tile 1 in the front-rear direction at a construction site or the like. This tile 1 can be easily and accurately cut and divided by moving a rotating rotary blade such as a circular saw along the vertical grooves 19.

Furthermore, the tile main body part 2 shown in FIGS. 3 and 5 is provided with reinforcing ribs 20 on the back surface 2B side at positions corresponding to the vertical grooves 19 provided on the upper surface 2A. This structure has a feature that the rigidity of the tile 1 can be maintained by ensuring that the reduction in strength due to the vertical grooves 19 provided on the top surface 2A is compensated by the reinforcing ribs 20 provided on the back surface 2B. The reinforcing ribs 20 provided on the back surface 2B have their front ends connected to the laminated protrusions 14 and their rear ends connected to the positioning protrusions 17 to increase strength. The reinforcing rib 20 preferably has a total length in the front-rear direction longer than the total length of the vertical groove 19 and a width wider than the opening width of the vertical groove 19. However, the roof tile 1 does not necessarily need to be provided with the vertical grooves 19 on the upper surface 2A, and may also be provided with vertical ribs. A roof tile including vertical ribs can further increase the strength against bending stress in the front-rear direction at the center of the roof tile main body. Note that the strength of the roof tile 1 can be increased by providing reinforcing ribs 20 on the back surface 2B, regardless of the presence or absence of the vertical grooves 19 on the top surface 2A.

The upper surface 2A of the tile body 2 described above can have a smooth planar surface, a regular uneven surface, or an irregular uneven surface. For example, the tile main body part 2 is formed by shaping the surface condition in the area excluding the laminated area where the tiles 1 in the back row are laminated (the exposed area indicated by the working length (Dh) in FIG. 2) into the shape of a rock surface made by splitting natural stone. It is also possible to form an irregularly uneven surface.

(ridge side through hole 7)
Further, the tile 1 has a ridge side through hole 7 opened at the ridge side rear end portion 5. This ridge side through hole 7 will be described in detail later, but when the eave side front end portion 4 of the tiles 1 placed in the back row is stacked, the eave side through hole 6 of the tile 1 placed in the back row is coaxial. , and the connector 9 is inserted therethrough. Therefore, this ridge-side through hole 7 also functions as a positioning member that specifies the stacking position of tiles 1 arranged in the back row. For example, as shown in FIG. 7, the plurality of tiles 1 arranged in a plurality of rows in the front and back are arranged in a staggered manner, with the tiles 1 arranged on the eaves side and the tiles 1 arranged on the ridge side. Therefore, in the tile 1, the ridge-side through holes 7 are opened so that the ridge-side tiles 1 are arranged in a staggered position with respect to the eaves-side tiles 1.

However, the tiles 1 placed in the back row do not necessarily need to be placed in a staggered position with respect to the tiles 1 in the front row. The tile 1 shown in the figure has a plurality of ridge-side through holes 7 opened along the ridge-side rear edge 12. With this tile 1 placed on the eaves side, the stacking position of the tiles 1 placed on the ridge side can be changed by selecting a plurality of ridge side through holes 7. The tile shown in the figure has five ridge-side through holes 7 spaced apart along the ridge-side rear edge 12, so that the connection position of the tiles 1 stacked on the ridge side can be changed in various ways. . In the figure, among the five ridge-side through-holes 7, the middle ridge-side through-hole 7 is used as a through-hole for arranging tiles 1 arranged on the ridge side in a staggered manner.

The above-mentioned ridge-side through-hole 7 is provided so that its opening is located on the upper end surface of the waterstop ridge 14. The waterstop ridge 14 shown in FIG. 1 has a truncated cone or truncated pyramid shaped pedestal, and a ridge-side through hole 7 is opened in the center of the pedestal. In this way, the structure in which the ridge side through hole 7 is provided so that the opening is located on the upper end surface of the pedestal provided on the waterstop ridge 14 prevents rainwater etc. from entering the interior through the ridge side through hole 7. It has the advantage of being able to prevent the strength of the water stop protrusion 14 from decreasing while also preventing this from occurring.

(Step connection part 3)
As shown in the cross-sectional view of FIG. 5, the tile 11 is provided with a low stepped connecting portion 3 on one side edge in order to overlap and connect the tiles 1 adjacent to each other in the left and right direction. The step connecting portion 3 shown in the figure is integrally formed on the left side edge 28 of the tile main body portion 2. The step connecting portion 3 is connected to the tile main body portion 2 via a standing reinforcing rib 21 provided on a side edge 28 of the tile main body portion 2. The rising reinforcing rib 21 has a lower end connected to the step connection 3 and an upper end connected to the upper surface 2A of the tile main body part 2. The upright reinforcing rib 21 shown in FIG. 5 has an outer surface connected to the step connecting portion 3, and an inner surface having a tapered surface that gradually becomes thicker upward, thereby increasing the strength of the connecting portion.

As shown in FIG. 4, the step connecting portion 3 has a front end portion on the eave side bent downward to form a laminated convex portion 24. As shown in FIG. 6, the laminated convex portion 24 is formed when the eave side front end 4 of the tile 1 placed on the ridge side is stacked on the ridge side rear end 5 of the tile 1 placed on the eave side. , is a portion placed on the upper surface 2A of the tile 1 placed on the eaves side. The step connecting part 3 has the laminated convex part 24 at the front end so as to be located inside the laminated convex strip 14 of the tile main body part 2 with the tile main body part 2 of the adjacent tile 1 stacked on the upper surface. It is arranged at a position lowered to the rear than the laminated convex strip 14 of the tile main body part 2. The step connecting part 3 is provided with a running water groove 22 extending in the front-rear direction, and has a structure in which rainwater that enters from between the left and right adjacent tiles 1 is guided to the running water groove 22 and flows toward the eaves side. The water flow groove 22 of the stepped connecting portion 3 has a front end open above the laminated convex portion 24 and a rear end closed by the rear end protrusion 16 .

(Eave side through hole 6)
The step connecting portion 3 is provided with an eave side through hole 6 opened on the eave side front edge 11 side. This eave side through hole 6 is connected to the ridge side through hole 7 of the tile 1 placed in the front row when stacking the tile 1 placed in the back row on the ridge side rear end 5 of the tile 1 placed in the front row. They are arranged coaxially and the connector 9 is inserted therethrough. Therefore, this eave side through hole 6 is provided at the ridge side rear end 5 of the front row tile 1 with the laminated convex portion 24 of the step connecting portion 3 arranged on the upper surface of the rear end of the front row tile 1. It is provided at a position facing the ridge side through hole 7. As shown in FIG. 2, the eave side through hole 6 opened in the step connection part 3 is such that the distance (d) between the eave side through hole 6 and the eave side front edge 11 is the same as the ridge side of the roof tiles 1 that are stacked on each other. It is provided so as to be shorter than the lap width (S) between the rear end portion 5 and the eave side front end portion 4 of the tile 1.

The distance (d) between the eave side through hole 6 and the eave side front edge 11 is 40% or less of the total length (D) of the tile 1, preferably 30% or less, and more preferably 20% or less. For example, in the tile 1 having a total length (D) of 350 mm, the distance (d) between the eave side through hole 6 and the eave side front edge 11 is 140 mm or less, preferably 70 mm or less. Here, if the distance (d) between the eave side through hole 6 and the eave side front edge 11 is shortened, the lap width (S) between the roof tiles 1 stacked one after another can be shortened, and the working length of the roof tiles 1 can be shortened. By increasing the height (Dh), tiles 1 can be efficiently installed while reducing the number of tiles 1 per unit area. On the other hand, if the distance (d) between the eave side through hole 6 and the eave side front edge 11 is increased, the working length (Dh) of the tile 1 becomes smaller, but The wrap width (S) can be increased, and rain and wind can be effectively prevented from penetrating through the laminated portion. Therefore, the distance (d) between the eave side through-hole 6 and the eave side front edge 11 is optimal considering the lap width (S) and working length (Dh) of the roof tiles 1 stacked in front and behind each other. Design the length. The tile 1 shown in FIG. 1 has a total length (D) of 350 mm, a lap width (S) of 70 mm, and a distance (d) between the eave side through hole 6 and the eave side front edge 11 of about 50 mm.

The eaves side through-hole 6 described above is provided so that its opening is located on the upper surface of the bank of the running water groove 22. The roof tile shown in FIG. 1 is provided with a truncated conical pedestal on the bank of the water channel 22, and an eave side through-hole 6 opened in the center of the pedestal. In this way, the structure in which the eave side through hole 6 is provided so that the opening is located on the upper end surface of the pedestal provided on the bank prevents rainwater etc. from entering the interior through the eave side through hole 6. However, it has the advantage of preventing the strength of the bank from decreasing.

Furthermore, the tile 1 shown in FIGS. 1 and 2 has a sub-through hole 26 opened at a central portion of the step connecting portion 3 and at a position spaced apart from the eaves side through hole 6 toward the rear end side. This sub-through hole 26 has a distance (k) from the eave side front edge 11 that is larger than the lap width (S) between the ridge side rear end 5 of the tile 1 and the eave side front end 4 of the tile 1 which are stacked together. It is also set so that it is longer. This sub-through hole 26 is used when further firmly fixing the tile 1 fixed with the connecting tool 9 inserted through the eave side through hole 6 and the ridge side through hole 7, or when When fixing the tile 1 to the base 30 without inserting the connector 9 into the hole 7, or when fixing the tile 1 that is closest to the eaves of the roof and that constitutes the first row to the base 30. It can be used when fixing (see FIG. 8 described later). Further, like the eaves side through holes 6, the sub through holes 26 are arranged coaxially with the ridge side through holes 7 of the tiles 1 arranged in the lower row, and penetrate the sub through holes 26 and the ridge side through holes 7. It can also be fixed to the substrate via a connector. In this case, the lap width (S) between the tiles arranged in the front row and the tiles arranged in the back row is larger than the distance (k) from the sub-through hole 26 to the front edge 11 of the eave side. However, this sub-through hole can also be omitted.

The tile 11 shown in FIG. 5 is provided with a wrap portion 23 on the side edge opposite to the step connection portion 3, which overlaps the step connection portion 3. The wrap portion 23 is shaped so that its lower surface is in uniform contact with the top of the step connection portion 3 . Furthermore, the tile 1 does not have the rear end protrusion 16 at the rear end of the wrap part 23, and the rear end protrusion 16 is not provided at the rear end of the step connecting part 3 of the tiles 1 that are stacked adjacently on the left and right. A fitting recess 25 for guiding the protrusion 16 is provided.

The above roof tile 1 has a rectangular outer dimension in a plan view, with a total length (D) in the front-rear direction of 350 mm and a total width (W) in the left-right direction of 344 mm. Further, in the tile 1, the width (Wd) of the step connecting portion 3 is 38 mm, and the width of the tile main body portion 2, which is the working width (Wh) of the tile 1, is 306 mm. This tile 1 has a lap width (S) of 70 mm between the tiles 1 stacked on the front and back, so that the working length (Dh) of the tile 1 exposed on the surface when it is covered on a roof is 280 mm. The number of tiles 1 can be approximately 12 per ^square meter of roof area. Note that these dimensions are just examples, and can be changed in various ways depending on the type and purpose of the tile 1, for example, the material and shape of the tile, the size and slope of the roof to be constructed, etc. The tiles can have, for example, a total length (D) of 200 to 500 mm, preferably 300 to 400 mm, and a total width (W) of 200 to 500 mm, preferably 250 to 400 mm. Further, the tile can have a horizontal width (Wd) of the step connecting portion 3 of 20 to 50 mm, preferably 25 to 40 mm, and a working width (Wh) of the tile 1 of 160 to 475 mm, preferably 200 to 380 mm. . Furthermore, the working length (Dh) of the tile exposed to the surface when it is placed on the roof is 1/2 or more, preferably 2/3 or more of the total length (D) of the tile. The lap width (S) of the roof tiles 1 to be laminated at the front and rear is determined. The wrap width (S) is 5 to 50%, preferably 10 to 30%, of the total length (D) of the tile 1, for example, 30 to 200 mm, preferably 40 to 100 mm.

Furthermore, the connector 9 is inserted into the eave side through hole 6 and the ridge side through hole 7 arranged coaxially (see FIGS. 6 and 7), and the connector 9 is inserted through the ridge side through hole 7 and the eave side through hole 6. The connector 9 is fixed to the horizontal beam 31 (fixing step). Similarly, a plurality of roof tiles 1 constituting the second row are installed while being connected in the left-right direction.

Furthermore, in the same way as the above process, for the third row and beyond, a plurality of roof tiles 1 are connected on the left and right and front and back and roofed at predetermined positions while repeating the front and back laminating process and the fixing process. That is, a plurality of tiles 1 arranged in multiple rows, where n is a natural number, are connected to the ridge side through-hole 7 of the tile 1 arranged in the nth row and the eave side of the tile 1 arranged in the (n+1)th row. Place the eave side front end 4 of the ridge side tile 1 on top of the ridge side rear end 5 of the eave side tile 1 so that the through hole 6 is coaxial with the eave side tile 1 (front and rear lamination process), and The connector 9 is inserted into the eave side through hole 6 and the ridge side through hole 7 arranged in the ridge side through hole 6, and the connector 9 passing through the ridge side through hole 7 and the eave side through hole 6 is fixed to the horizontal beam 31. (Fixing step) By this, a large number of tiles 1 are installed in multiple rows in a predetermined arrangement.

[Connector 9]
The connector 9 that fixes the tile 1 to the base 30 may be a member that is screwed onto the base such as a set screw or a screw, or a member that is fixed by being driven into the base such as a nail or pin. Preferably, it is determined by the material of the base 30. For example, when the base is a shaped steel such as a lightweight steel frame, tapping screws, screws, bolts, etc. are used as the connectors, and when the base is a wooden material such as square lumber or concrete panels (plywood for formwork). Set screws such as wood screws, nails, pins, etc. can be used. Furthermore, in addition to the connecting tool 9, an adhesive can be used in conjunction with the connector 9 to more firmly fix the connecting portions between the tiles and the connecting portions between the tiles and the base.

According to the above construction method, when fixing the tiles 1 from the second row onwards to the base 30, the tiles 1 arranged in a stacked manner in front and back are connected to each other through the eave side through hole 6 and the ridge side through hole. It is fixed to the base 30 through only one connector 9 inserted through the base 30. Therefore, one connector 9 can be used to fix each tile 1. Therefore, compared to the conventional construction method, the number of locations where the tiles 1 are fixed can be halved, labor-saving fixing work and shortened working time, and construction costs can be reduced by saving the number of connectors 9. can be reduced.

In addition, a connector inserted into the eave-side through-hole 6 provided close to the eaves side of the tiles 1 arranged in the back row is inserted into the ridge-side through-hole 7 of the tiles 1 in the front row and fixed to the base 30. Therefore, since the eaves side of the tile 1 to be stacked is fixed in a state where it is pressed against the tile 1 in the front row, the front end portion of the tile 1 stacked above, close to the front edge 11 of the eave side, is fixed to the base 30, and the upper It is possible to effectively prevent the tiles 1 from coming off due to strong winds.

Furthermore, since the tiles that are stacked on each other are fixed to the base via the connectors that pass through the laminated portions, the tiles in the stacked state can be fixed to the base while providing excellent connection strength. Therefore, it is possible to effectively prevent roof tiles stacked above from coming off due to strong winds.

TECHNICAL FIELD The present invention relates to a tile construction method, a roof structure , and a tile used in these methods and structures .

BACKGROUND OF THE INVENTION Finishing the roof structure of houses with tiles has been a well-known technique since ancient times. In recent years, cement tiles made of hardened cement or mortar, and slate tiles made of cement mixed with fiber materials, have been used instead of the traditional tiles made of molded and fired clay. These cement tiles are thinner and lighter than conventional clay tiles, making them suitable for mass production. Reducing the weight of tiles has the advantage of reducing the load on building structures, including roofs, and making it easier to strengthen earthquake resistance.

An example of such a cement-based roof tile is shown in the plan view of FIG. The tile 91 shown in this figure is a flat tile that has a plate shape as a whole, and includes a tile main body 92 that is rectangular in plan view, and a tile that extends from the top surface of the tile main body 92 along one side edge of the tile main body 92. It also includes a step connecting portion 93 formed one step lower. As shown in FIG. 12, these roof tiles 91 are arranged by stacking tiles 91 that are adjacent to each other in the left and right direction at the step connecting portion 93, thereby connecting the roof tiles in the left and right direction so that their top surfaces are on the same plane. At the same time, tiles placed in the front and rear directions are arranged so that the front ends of the tiles 91 placed in the front row are partially overlapped with the front ends of the tiles 91 placed in the front row, so that the tiles are adjacent to each other in the front and back directions. The roof tiles are connected with each other in a stepped structure to prevent rainwater from seeping into the interior.

This type of roof tile 91 generally has a plurality of through holes 94 and 95 opened in advance, as shown in the plan view of FIG. The tool 99 is fixed at a fixed position by being fixed to a base provided on the surface that will become the roof of the building. The tile shown in FIG. 11 has through holes 94 and 95 in the center of a step connecting portion 93 provided on the side edge and on both sides of the rear end of the tile main body 92 on the ridge side.

The tiles 91 having this structure are arranged in the back row by, for example, a construction method in which a connecting tool 99 is inserted into the through holes 94 at the positions indicated by A and B at the rear end of the tile main body 92 shown in FIG. 11 and fixed. The tiles 91 can be fixed to the base. In this case, since the connectors can be arranged in a horizontal row, the number of horizontal bars to be arranged in advance can be reduced when the base for fixing the connectors is a horizontal bar. However, in this structure, the distance (L1) between the position where the tile 91 is fixed to the base with the connector 99 and the front edge 91A of the tile 91 becomes large, so the front end side of the tile in the back row is placed on the top surface of the tile in the front row. There is a problem in that the pressing force becomes smaller and wind, rainwater, etc. easily enter through this boundary.

On the other hand, a connector 99 is inserted and fixed into the through hole 94 at the position indicated by A in the rear end of the tile main body 91 shown in FIG. Depending on the construction method, the tiles 91 placed in the back row can be fixed to the base. In this case, since the two connectors 99 for fixing one tile 91 are disposed approximately in the diagonal direction of the tile 91, the position where the tile 91 is fixed to the base by the connector 99 and The distance (L2) from the front end edge 91A can be shortened. For this reason, it is possible to increase the force with which the front end of the tiles in the rear row is pressed against the top surface of the tiles in the front row, thereby effectively preventing wind, rainwater, etc. from entering through the boundary portion. However, according to this structure, as shown in FIG. Since it is necessary to arrange horizontal bars 98B for fixing the connectors 99, there is a problem in that construction of the base 98 requires time and cost.

Here, as a base for fixing tiles, flat plates such as roofing boards may be laid on the surface that will form the roof. In this case, it is also possible to omit the horizontal beam for fixing the connector that is inserted through the through hole of the step connector, and to directly fix this connector to the roof board. However, according to this structure, the connector that is inserted through the step connection part is fixed to the roofing board while the front end of the rear row of tiles overlaps the rear end of the front row of tiles, so the lower surface of the step connection and the roofing board are fixed. A gap is created between the two and the step connecting part cannot be firmly fixed to the base. Therefore, in order to firmly fix the connector that is inserted through the step connection part to the base, it is preferable to place a member such as a horizontal bar at the position of the through hole of the step connection part, which saves time and cost in the construction of the base. There were such problems.

In addition, in conventional construction methods, at least two connectors are used to secure each tile, so as the number of tiles increases, the amount of work required to insert connectors into each through hole and secure the tiles increases. There were problems in that the work of fixing tiles was time-consuming and the number of parts increased, increasing construction costs.

Japanese Patent Application Publication No. 2007-009655

The present invention has been made in view of this background, and one of its objectives is to reduce construction costs while efficiently fixing roof tiles, and to securely and securely secure tiles that are stacked on top of each other. The purpose of the present invention is to provide a construction method and roof structure of tiles that can be firmly connected , and tiles used for these methods and structures .

Means for solving the problem and effects of the invention

According to the tile construction method according to the first aspect of the present invention, a plurality of tiles are installed on a surface constituting the roof of a building in a state in which they are connected to each other in the front, back, left and right directions. A tile having a rectangular shape in plan view having a front edge on the eave side and a rear edge on the ridge side facing each other in the front and back, and both side edges facing left and right , the tile body having a rectangular shape in plan view, and the tile body part having a rectangular shape in plan view. A step connecting part formed one step lower than the other side edge is formed on one side edge of the step connecting part, and an eave side through hole opened on the front edge side of the eave side of the step connecting part, and an eave side through hole that extends from the eave side through hole to the ridge side . A plurality of tiles each having a sub-through hole opened in the center of the step connection part at a distance from each other, and a ridge side through hole opened at the rear end of the tile main body part on the ridge side, in the tile main body part . In the tile preparation process, a plurality of tiles are connected in the horizontal direction by stacking adjacent tiles on the left and right at the step connection part on the surface that forms the roof of the building where the foundation has been prepared in advance. The method includes a roofing process in which a plurality of tiles are arranged in a plurality of rows from the eaves side to the ridge side, forming rows of tiles, and the roof is covered with tiles. The roofing process consists of a first row fixing process in which the tiles placed in the row closest to the eaves are fixed to the base via connectors inserted through the sub-through holes, and The ridge-side through-hole is coaxial with the eave-side through-hole or sub-through-hole of the tile placed on the ridge. In the front and back lamination process in which the front ends of the eaves sides of the tiles to be placed are overlapped, and in the front and rear lamination process, a connector is inserted into the eave side through hole or sub through hole and the ridge side through hole that are coaxially arranged. The method includes a fixing step of fixing a connector passing through the ridge-side through-hole and the eave-side through-hole or the sub-through-hole to the base.

According to the above construction method, tiles that are adjacent to each other in the front and back direction are fixed to the base via a connector that penetrates the laminated portion of each other, so two adjacent tiles can be fixed at the same time by fixing in one place, which is different from the conventional method. Compared to the previous construction method, the number of locations for fixing tiles can be halved, saving labor for fixing tiles, shortening the construction period, and providing the excellent advantage of reducing construction costs.

According to the tile construction method according to the third aspect of the present invention, the distance (d) between the eave side through hole opened in one side edge of the tile and the front edge of the eave side is The lap width (S) between the ridge-side rear end of the tile placed on the eave side and the eave-side front end of the tile placed on the ridge side.

According to the above construction method, the connecting tool is inserted into the eave-side through-hole provided on the eaves side so that the distance between the tiles on the eave side is shorter than the stacked width of the tiles stacked on the ridge side. Since the roof tiles are fixed to the base, tiles stacked on top of each other can be reliably fixed to the base at the laminated portions. Therefore, the roof tiles stacked above can withstand strong wind pressure and will not easily come off even when exposed to strong winds.

According to the tile construction method according to the fourth aspect of the present invention, the distance (d) between the eave side through hole and the front edge of the eave side is set to 40% or less of the total length (D) of the tile in the front-rear direction.

According to the above construction method, the position of the eave side through hole that opens in the tile is on the front edge of the eave side, and is at a position that is 40% or less of the total length (D) in the front and back direction of the tile. By fixing the front end portion of the roof tile close to the front edge of the eave side to the base, it is possible to effectively prevent the upper tile from coming off due to strong winds.

According to the tile construction method of the present invention, the ridge side through-holes of the tile can be opened at positions where the tiles arranged on the ridge side are arranged in a staggered manner with respect to the tiles arranged on the eaves side.

According to the above construction method, the ridge side through-holes are provided in positions where the tiles placed on the ridge side are arranged in a staggered manner relative to the tiles placed on the eave side, so To easily and accurately lay a plurality of tiles arranged in a plurality of rows in a staggered manner to create a beautiful appearance.

According to the tile construction method according to the fifth aspect of the present invention, the base provided in advance on the surface constituting the roof of the building is arranged in a plurality of rows extending in the left-right direction at predetermined intervals and parallel to each other. In the front and rear lamination process, the ridge side through-hole of the tile placed on the eave side and the eave side through-hole or sub-through hole of the tile placed on the ridge side are coaxially connected on the horizontal crosspiece. Each tile is supported by two rows of horizontal bars, front and back.

According to the above construction method, multiple rows of horizontal bars extended in the left and right direction in parallel positions are used as the base for fixing the tiles, which simplifies the base structure and allows multiple tiles to be installed at low cost. It can be installed on the roof.

According to the tile construction method according to the second aspect of the present invention, a plurality of tiles are installed on a surface constituting the roof of a building in a state in which they are connected to each other in the front, back, left and right directions. The eaves are rectangular in plan view and have a front edge of the eave side and a rear edge of the ridge side facing each other in the front and back, and both side edges facing left and right, and have an opening on the front edge side of the eave side of one side edge. A tile preparation process of preparing a plurality of tiles each having a side through-hole and a ridge-side through-hole opened at the rear end of the ridge; The method includes a roofing process in which a plurality of tiles are arranged in a plurality of rows from the eaves side to the ridge side, and the tiles are connected in the left and right direction to form rows, and the roof is covered with tiles.

Furthermore, according to the tile construction method according to the second aspect of the present invention, the tile prepared in the tile preparation step is provided with a plurality of ridge-side through holes opened along the ridge-side rear edge. In the front and rear lamination process, a plurality of ridge-side through holes of the tiles arranged on the eaves side are selected, and the eave-side through holes of the tiles arranged on the ridge side are arranged coaxially.

According to the above construction method, when the front end of the ridge side tile is overlapped with the ridge side rear end of the tile placed on the eave side, the eave side through hole of the ridge side tile is arranged. By selecting the holes, the tiles on the ridge side can be placed in the optimal position relative to the tiles on the eave side. Thereby, by changing the ridge-side through-hole that is aligned with the eave-side through-hole, it is possible to change the connection position in the left-right direction between tiles that are adjacent to each other in the front and back. As a result, the width of the tile roof structure can be changed depending on the shape and size of the roof of the building. It is also possible to adjust the area where tiles are overlapped depending on the required specifications such as the size, strength, and water resistance of the roof of the building.

According to the tile construction method of the present invention, the tile prepared in the tile preparation step has a tile main body that is rectangular in plan view, and one side edge of the tile main body that is one step higher than the top surface of the tile main body. It is equipped with a low-shaped step connection part, and an eave side through hole is opened in the step connection part, so that tiles adjacent on the left and right can be stacked and connected to each other at the step connection part during the roofing process. .

Embodiments of the present invention will be described below based on the drawings. However, the embodiment shown below is an illustration for embodying the technical idea of the present invention, and the present invention is not limited to the following method and structure. Moreover, this specification does not in any way specify the members shown in the claims to the members of the embodiments. In particular, the dimensions, materials, shapes, relative positions, etc. of the components described in the embodiments are not intended to limit the scope of the present invention, unless otherwise specified, and are merely illustrative. Just an example. Note that the sizes, positional relationships, etc. of members shown in each drawing may be exaggerated for clarity of explanation. Furthermore, in the following description, the same names and symbols indicate the same or homogeneous members, and detailed descriptions will be omitted as appropriate. Furthermore, each element constituting the present invention may be configured so that a plurality of elements are made of the same member so that one member serves as a plurality of elements, or conversely, the function of one member may be performed by a plurality of members. It can also be accomplished by sharing.

The tile construction method of the present invention is a method in which a plurality of tiles are installed on a surface forming the roof of a building in a state in which they are connected to each other in the front, back, right and left directions. This construction method includes a tile preparation process of preparing a plurality of tiles, and a roofing process of covering a roof with a plurality of tiles.

[Tile preparation process]
In the tile preparation step, a plurality of tiles 1 formed into a predetermined shape are prepared. As shown in the perspective view of FIG. 1 and the plan view of FIG. 2, this tile 1 is a flat surface having a front edge 11 on the eave side and a rear edge 12 on the ridge side facing each other in the front and back, and both side edges 13 facing left and right. It has a rectangular shape when viewed, and has an eave side through hole 6 opened on the eave side front edge 11 side of one side edge, and a ridge side through hole 7 opened on the ridge side rear end 5. . An example of the roof tile 1 having this structure will be described in detail below.
In addition, in this specification, the front, back, left, and right directions of the roof tile are determined based on FIG. 2. That is, the lower direction in FIG. 2 is the front direction of the tile, the upper direction is the back direction of the tile, and the left-right direction in FIG. 2 is the left-right direction of the tile.

(tile 1)
The tile 1 shown in FIGS. 1 and 2 is a flat tile 1A whose overall shape is a flat plate. The flat tile 1A shown in the figure is a slate tile manufactured into a plate shape by press-molding mortar containing cement and fine aggregate, and has a paint film applied to its surface. Sand and fly ash are used as fine aggregate to be mixed with cement. However, it is also possible to use only sand as the fine aggregate without adding fly ash. Furthermore, preferably, in addition to fine aggregate, lightweight aggregate can also be added to the mortar. The tile 1 formed by adding lightweight aggregate has the advantage that it can be made more lightweight, has improved thermal conductivity, and can effectively prevent cracking when frozen. The lightweight aggregate used is plastic foamed into a spherical shape, or inorganic material foamed and sintered into a spherical shape. Furthermore, reinforcing fibers are preferably added to the mortar for forming the roof tile 1. For example, vinylon fiber or alkali-resistant glass fiber is used as the reinforcing fiber added to the mortar. In this way, by adding reinforcing fibers, the strength of the roof tile 1 can be increased. The thickness of the coating applied to the surface is preferably about 100 μm. However, the coating film can also have a thickness of 30 to 200 μm.

Furthermore, the roof tile 1 is not limited to a slate roof tile, and may be formed of various materials. For example, roof tiles may be made by firing a material such as clay molded into the shape of a roof tile, or may be a resin roof tile made by molding a synthetic resin such as polyvinyl chloride into a predetermined shape. Alternatively, a metal tile can be made by cutting a metal plate into a predetermined shape.

The tile 1 shown in FIGS. 1 to 5 includes a tile main body 2 having a rectangular shape in plan view, and one side edge 28 (the left edge in the figure) of the tile main body 2 on the other side of the tile main body 2. It is provided with a stepped connecting portion 3 formed one step lower than the upper surface 2A of the edge 13 (the right edge in the figure). Since the tile 1 shown in the figure is a flat tile 1A, a step connecting part 3 formed one step lower is integrally formed on one side edge 28 of the tile main body 2 whose upper surface 2A is flat. It is set up.

(Tile body part 2)
The tile main body 2 shown in FIGS. 3 to 5 has a plate shape with a flat upper surface 2A, and the tip of the eave side front end 4 is bent downward to form a laminated protruding strip 14. As shown in FIG. 6, the laminated protruding strips 14 are formed when the eave side front end 4 of the tile 1 placed on the ridge side is stacked on the ridge side rear end 5 of the tile 1 placed on the eave side. , is a portion placed on the upper surface 2A of the tile 1 placed on the eaves side. In this way, by bending the tip of the eave side front end 4 downward to form the laminated protruding strip 14, and by bringing the lower end surface of this laminated protruding strip 14 into contact with the upper surface 2A of the tile 1, It is possible to effectively prevent wind, rainwater, etc. from entering the interior from the boundaries between tiles 1. The laminated protruding strip 14 shown in FIG. 3 has an outer surface that is a vertical surface, and an inner surface that is a tapered surface that gradually becomes thicker upward. Furthermore, the tile main body part 2 shown in FIGS. 3 and 4 is provided with an inclined part 2C at the front end of the upper surface 2A. In the illustrated inclined portion 2C, the front edge of the upper surface 2A of the tile main body portion 2 is chamfered to form a downwardly inclined inclined surface. However, the roof tile 1 does not necessarily have to have an inclined part on the eaves side front end 4, and the front edge of the upper surface can be a right-angled corner part or a curved surface.

Further, the tile main body 2 shown in FIGS. 1 to 5 is provided with a waterstop ridge 15 along the rear edge in order to prevent rainwater blown up from below by the wind from entering. The water stop protrusion 15 is located closer to the eaves than the rear edge 12 on the ridge side, and is provided so as to extend to both sides of the tile main body part 2. As shown in FIG. 3, the water stop protrusion 15 has a trapezoidal cross-sectional shape whose width becomes gradually narrower toward the upper end surface, and the corners of the water stop protrusion 15 are made obtuse angles to prevent contact and collision. This makes it less susceptible to damage.

Further, the tile main body 2 is provided with a rear end protrusion 16 that protrudes rearward on the rear end side of the waterstop protrusion 15, and this rear end protrusion 16 has a positioning portion that protrudes downward. A protrusion 17 is provided. This positioning protrusion 17 is provided in order to arrange the tile 1 at a predetermined position and in a predetermined attitude when the tile 1 is placed on a base 30 provided on a roof. For example, when the base is a flat plate such as a field board, the height of the rear end 5 on the ridge side of the tile 1 can be made equal by bringing the lower end of the positioning protrusion 17 into contact with the surface of the field board. . In addition, as shown in FIG. 6, when the base 30 is a horizontal crosspiece 31 extending in the left-right direction, the positioning protrusion is By locking the tile 17 to the rear end surface of the horizontal beam 31, the tile 1 can be prevented from sliding toward the eaves. With this structure, when the roof of a building has a steep slope, it can be installed safely while placing the tiles in a fixed position.

However, the tile 1 does not necessarily have to be arranged with respect to the base 30, which is the horizontal crosspiece 31, in such a manner that the positioning protrusion 17 that protrudes downward from the rear end protrusion 16 is locked to the rear end surface of the horizontal crosspiece 31. Alternatively, as shown in FIG. 7, the lower end of the positioning protrusion 17 may be placed in contact with the upper surface of the horizontal bar 31 and fixed to the horizontal bar 31. The horizontal beam 31 shown in FIG. 7 is made by bending a metal plate so that the cross-sectional shape is a rectangular shape with a convex center, and the upper surface of the convex portion that is convex in the center serves as a mounting surface 31b on which tiles are placed. . The structure in which the roof tiles 1 are placed on the flat mounting surface 31b as described above has the advantage that the roof tiles 1 connected and arranged in the left-right direction can be arranged in a straight line accurately. In particular, the horizontal beams 31 can be arranged accurately in a straight line without being affected by warpage or deformation. This structure can be suitably used for roofs with a gentle slope.

The positioning protrusion 17 shown in FIG. 5 has a plurality of notches 17A in the center, and the tile 1 can be easily lifted up by inserting a fingertip or the like into the notch. Further, the rear end protrusion 16 is provided with a vertical rib 18 that projects upward corresponding to the position where the notch 17A of the positioning protrusion 17 is provided, and the rear end has a thinner thickness due to the notch 17A. The protrusion 16 is reinforced. In the tile 1 shown in the figure, the vertical ribs 18 are integrally formed from the water stop protrusion 15 toward the rear, so that the upper end surface of the vertical rib 18 and the upper end surface of the water stop protrusion 15 are on the same plane. .

Furthermore, the tile main body part 2 shown in the figure is provided with a plurality of rows of vertical grooves 19 extending in the front-rear direction in the central part. The tile main body 2 shown in the figure is provided with two rows of vertical grooves 19 at positions that are approximately divided into three in the width direction. Each longitudinal groove 19 is provided in an area excluding the rear end of the tile main body 2, and in an area excluding the laminated area where the front eaves side ends 4 of the tiles 1 arranged in the rear row are laminated. The tile 1 having the vertical grooves 19 at this position has the advantage that it can be easily cut along the vertical grooves 19 when cutting and dividing the tile 1 in the front-rear direction at a construction site or the like. This tile 1 can be easily and accurately cut and divided by moving a rotating rotary blade such as a circular saw along the vertical grooves 19.

Furthermore, the tile main body part 2 shown in FIGS. 3 and 5 is provided with reinforcing ribs 20 on the back surface 2B side at positions corresponding to the vertical grooves 19 provided on the upper surface 2A. This structure has a feature that the rigidity of the tile 1 can be maintained by ensuring that the reduction in strength due to the vertical grooves 19 provided on the top surface 2A is compensated by the reinforcing ribs 20 provided on the back surface 2B. The reinforcing ribs 20 provided on the back surface 2B have their front ends connected to the laminated protrusions 14 and their rear ends connected to the positioning protrusions 17 to increase strength. The reinforcing rib 20 preferably has a total length in the front-rear direction longer than the total length of the vertical groove 19 and a width wider than the opening width of the vertical groove 19. However, the roof tile 1 does not necessarily need to be provided with the vertical grooves 19 on the upper surface 2A, and may also be provided with vertical ribs. A roof tile including vertical ribs can further increase the strength against bending stress in the front-rear direction at the center of the roof tile main body. Note that the strength of the roof tile 1 can be increased by providing reinforcing ribs 20 on the back surface 2B, regardless of the presence or absence of the vertical grooves 19 on the top surface 2A.

The upper surface 2A of the tile body 2 described above can have a smooth planar surface, a regular uneven surface, or an irregular uneven surface. For example, the tile main body part 2 is formed by shaping the surface condition in the area excluding the laminated area where the tiles 1 in the back row are laminated (the exposed area indicated by the working length (Dh) in FIG. 2) into the shape of a rock surface made by splitting natural stone. It is also possible to form an irregularly uneven surface.

(ridge side through hole 7)
Further, the tile 1 has a ridge side through hole 7 opened at the ridge side rear end portion 5. This ridge side through hole 7 will be described in detail later, but when the eave side front end portion 4 of the tiles 1 placed in the back row is stacked, the eave side through hole 6 of the tile 1 placed in the back row is coaxial. , and the connector 9 is inserted therethrough. Therefore, this ridge-side through hole 7 also functions as a positioning member that specifies the stacking position of tiles 1 arranged in the back row. For example, as shown in FIG. 7, the plurality of tiles 1 arranged in a plurality of rows in the front and back are arranged in a staggered manner, with the tiles 1 arranged on the eaves side and the tiles 1 arranged on the ridge side. Therefore, in the tile 1, the ridge-side through holes 7 are opened so that the ridge-side tiles 1 are arranged in a staggered position with respect to the eaves-side tiles 1.

However, the tiles 1 placed in the back row do not necessarily need to be placed in a staggered position with respect to the tiles 1 in the front row. The tile 1 shown in the figure has a plurality of ridge-side through holes 7 opened along the ridge-side rear edge 12. With this tile 1 placed on the eaves side, the stacking position of the tiles 1 placed on the ridge side can be changed by selecting a plurality of ridge side through holes 7. The tile shown in the figure has five ridge-side through holes 7 spaced apart along the ridge-side rear edge 12, so that the connection position of the tiles 1 stacked on the ridge side can be changed in various ways. . In the figure, among the five ridge-side through-holes 7, the middle ridge-side through-hole 7 is used as a through-hole for arranging tiles 1 arranged on the ridge side in a staggered manner.

The above-mentioned ridge-side through-hole 7 is provided so that its opening is located on the upper end surface of the waterstop ridge 14. The waterstop ridge 14 shown in FIG. 1 has a truncated cone or truncated pyramid shaped pedestal, and a ridge-side through hole 7 is opened in the center of the pedestal. In this way, the structure in which the ridge side through hole 7 is provided so that the opening is located on the upper end surface of the pedestal provided on the waterstop ridge 14 prevents rainwater etc. from entering the interior through the ridge side through hole 7. It has the advantage of being able to prevent the strength of the water stop protrusion 14 from decreasing while also preventing this from occurring.

(Step connection part 3)
As shown in the cross-sectional view of FIG. 5, the tile 11 is provided with a low stepped connecting portion 3 on one side edge in order to overlap and connect the tiles 1 adjacent to each other in the left and right direction. The step connecting portion 3 shown in the figure is integrally formed on the left side edge 28 of the tile main body portion 2. The step connecting portion 3 is connected to the tile main body portion 2 via a standing reinforcing rib 21 provided on a side edge 28 of the tile main body portion 2. The rising reinforcing rib 21 has a lower end connected to the step connecting part 3 and an upper end connected to the upper surface 2A of the tile main body part 2. The upright reinforcing rib 21 shown in FIG. 5 has an outer surface connected to the step connecting portion 3, and an inner surface having a tapered surface that gradually becomes thicker upward, thereby increasing the strength of the connecting portion.

As shown in FIG. 4, the step connecting portion 3 has a front end portion on the eave side bent downward to form a laminated convex portion 24. As shown in FIG. 6, the laminated convex portion 24 is formed when the eave side front end 4 of the tile 1 placed on the ridge side is stacked on the ridge side rear end 5 of the tile 1 placed on the eave side. , is a portion placed on the upper surface 2A of the tile 1 placed on the eaves side. The step connecting part 3 has the laminated convex part 24 at the front end so as to be located inside the laminated convex strip 14 of the tile main body part 2 with the tile main body part 2 of the adjacent tile 1 stacked on the upper surface. It is arranged at a position lowered to the rear than the laminated convex strip 14 of the tile main body part 2. The step connecting part 3 is provided with a running water groove 22 extending in the front-rear direction, and has a structure in which rainwater that enters from between the left and right adjacent tiles 1 is guided to the running water groove 22 and flows toward the eaves side. The water flow groove 22 of the stepped connecting portion 3 has a front end open above the laminated convex portion 24 and a rear end closed by the rear end protrusion 16 .

(Eave side through hole 6)
The step connecting portion 3 is provided with an eave side through hole 6 opened on the eave side front edge 11 side. This eave side through hole 6 is connected to the ridge side through hole 7 of the tile 1 placed in the front row when stacking the tile 1 placed in the back row on the ridge side rear end 5 of the tile 1 placed in the front row. They are arranged coaxially and the connector 9 is inserted therethrough. Therefore, this eave side through hole 6 is provided at the ridge side rear end 5 of the front row tile 1 with the laminated convex portion 24 of the step connecting portion 3 arranged on the upper surface of the rear end of the front row tile 1. It is provided at a position facing the ridge side through hole 7. As shown in FIG. 2, the eave side through hole 6 opened in the step connection part 3 is such that the distance (d) between the eave side through hole 6 and the eave side front edge 11 is the same as the ridge side of the roof tiles 1 that are stacked on each other. It is provided so as to be shorter than the lap width (S) between the rear end portion 5 and the eave side front end portion 4 of the tile 1.

The distance (d) between the eave side through hole 6 and the eave side front edge 11 is 40% or less of the total length (D) of the tile 1, preferably 30% or less, and more preferably 20% or less. For example, in the tile 1 having a total length (D) of 350 mm, the distance (d) between the eave side through hole 6 and the eave side front edge 11 is 140 mm or less, preferably 70 mm or less. Here, if the distance (d) between the eave side through hole 6 and the eave side front edge 11 is shortened, the lap width (S) between the roof tiles 1 stacked one after another can be shortened, and the working length of the roof tiles 1 can be shortened. By increasing the height (Dh), tiles 1 can be efficiently installed while reducing the number of tiles 1 per unit area. On the other hand, if the distance (d) between the eave side through hole 6 and the eave side front edge 11 is increased, the working length (Dh) of the tile 1 becomes smaller, but The wrap width (S) can be increased, and rain and wind can be effectively prevented from penetrating through the laminated portion. Therefore, the distance (d) between the eave side through hole 6 and the eave side front edge 11 is optimal considering the lap width (S) and working length (Dh) of the roof tiles 1 stacked in front and back. Design the length. The tile 1 shown in FIG. 1 has a total length (D) of 350 mm, a wrap width (S) of 70 mm, and a distance (d) between the eave side through hole 6 and the front edge 11 of the eave side of about 50 mm.

The eaves side through-hole 6 described above is provided so that its opening is located on the upper surface of the bank of the running water groove 22. The roof tile shown in FIG. 1 is provided with a truncated conical pedestal on the bank of the water channel 22, and an eave side through-hole 6 opened in the center of the pedestal. In this way, the structure in which the eave side through hole 6 is provided so that the opening is located on the upper end surface of the pedestal provided on the bank prevents rainwater etc. from entering the interior through the eave side through hole 6. However, it has the advantage of preventing the strength of the bank from decreasing.

Furthermore, the tile 1 shown in FIGS. 1 and 2 has a sub-through hole 26 opened at a central portion of the step connecting portion 3 and at a position spaced apart from the eaves side through hole 6 toward the rear end side. This sub-through hole 26 has a distance (k) from the eave side front edge 11 that is larger than the lap width (S) between the ridge side rear end 5 of the tile 1 and the eave side front end 4 of the tile 1 which are stacked together. It is also set so that it is longer. This sub-through hole 26 is used when further firmly fixing the tile 1 fixed with the connecting tool 9 inserted through the eave side through hole 6 and the ridge side through hole 7, or when When fixing the tile 1 to the base 30 without inserting the connector 9 into the hole 7, or when fixing the tile 1 that is closest to the eaves of the roof and that constitutes the first row to the base 30. It can be used when fixing (see FIG. 8 described later). Further, like the eaves side through holes 6, the sub through holes 26 are arranged coaxially with the ridge side through holes 7 of the tiles 1 arranged in the lower row, and penetrate the sub through holes 26 and the ridge side through holes 7. It can also be fixed to the substrate via a connector. In this case, the lap width (S) between the tiles arranged in the front row and the tiles arranged in the back row is larger than the distance (k) from the sub-through hole 26 to the front edge 11 of the eave side.

The tile 11 shown in FIG. 5 is provided with a wrap portion 23 on the side edge opposite to the step connection portion 3, which overlaps the step connection portion 3. The wrap portion 23 is shaped so that its lower surface is in uniform contact with the top of the step connection portion 3 . Furthermore, the tile 1 does not have the rear end protrusion 16 at the rear end of the wrap part 23, and the rear end protrusion 16 is not provided at the rear end of the step connecting part 3 of the tiles 1 that are stacked adjacently on the left and right. A fitting recess 25 for guiding the protrusion 16 is provided.

The above roof tile 1 has a rectangular outer dimension in a plan view, with a total length (D) in the front-rear direction of 350 mm and a total width (W) in the left-right direction of 344 mm. Further, in the tile 1, the width (Wd) of the step connecting portion 3 is 38 mm, and the width of the tile main body portion 2, which is the working width (Wh) of the tile 1, is 306 mm. This tile 1 has a lap width (S) of 70 mm between the tiles 1 stacked on the front and back, so that the working length (Dh) of the tile 1 exposed on the surface when it is covered on a roof is 280 mm. The number of tiles 1 can be approximately 12 per ^square meter of roof area. Note that these dimensions are just examples, and can be changed in various ways depending on the type and purpose of the tile 1, for example, the material and shape of the tile, the size and slope of the roof to be constructed, etc. The tiles can have, for example, a total length (D) of 200 to 500 mm, preferably 300 to 400 mm, and a total width (W) of 200 to 500 mm, preferably 250 to 400 mm. Further, the tile can have a horizontal width (Wd) of the step connecting portion 3 of 20 to 50 mm, preferably 25 to 40 mm, and a working width (Wh) of the tile 1 of 160 to 475 mm, preferably 200 to 380 mm. . Furthermore, the working length (Dh) of the tile exposed to the surface when it is placed on the roof is 1/2 or more, preferably 2/3 or more of the total length (D) of the tile. Determine the wrap width (S) of the roof tiles 1 to be laminated at the front and rear. The wrap width (S) is 5 to 50%, preferably 10 to 30%, of the total length (D) of the tile 1, for example, 30 to 200 mm, preferably 40 to 100 mm.

[Roof installation process]
In the roofing process, the tiles 1 having the above-described structure are installed on a surface forming the roof of a building by connecting a plurality of tiles in a stacked manner in the left, right, front and rear directions.

It includes a fixing process.

In a tile construction method according to an embodiment of the present invention, a plurality of tiles 1 are installed on a surface constituting the roof of a building in the following manner.

[Construction process of foundation 30]
In this step, a base 30 for supporting and fixing a large number of tiles 1 is constructed on the surface that constitutes the roof of the building. In the roof structure shown in FIGS. 6 and 7, a plurality of horizontal beams 31 are used as a base 30 for fixing a plurality of tiles 1. The roof structure shown in FIGS. 6 and 7 has a plurality of rafters 32 arranged on the surface constituting the roof so as to extend in the front-rear direction in an inclined position from the ridge of the roof toward the eaves. A plurality of horizontal bars 31 are arranged on the upper surface of the rafter 32 so as to be parallel to each other and extend in the left-right direction, and are fixed at predetermined intervals to form the base 30. The horizontal beam 31 shown in FIG. 6 is a lightweight steel frame, for example, a steel section, and is a U-shaped member 31A having a U-shaped cross section. The horizontal beam 31 shown in FIG. 7 is a convex strip member 31B made by bending a metal plate into a rectangular shape with a convex center. This convex strip 31B is arranged such that the bent portions on both sides are fixed to the rafters 32, and the upper surface of the central convex portion is used as a mounting surface 31b, and the positioning protrusion 17 is placed on this mounting surface 31b. ing. However, for the horizontal bar 31, it is also possible to use a shaped steel having a C-shaped cross section, an angle having an L-shaped cross section, or the like.

Furthermore, although not shown, the base can also be made of wood. The wooden base may be, for example, sheathing boards spread over the surface of the roof, and a waterproof sheet may also be laid on the surface of the shedding boards. Alternatively, horizontal bars extending in the left-right direction may be fixed to the surface of the roof board, and tiles in each row may be connected to the horizontal bars in a locked state.

[Fixing tile 1 constituting the first row]
As shown in FIG. 8, a plurality of tiles 1 constituting the first row are arranged at predetermined positions and fixed to the base 30. The tiles 1 constituting the first row are arranged such that the positioning protrusion 17 on the rear end portion 5 of the ridge side is engaged with the horizontal beam 31 (X2 in FIG. 8) (see FIG. 6), or The connector 9 placed on the mounting surface 31b (see FIG. 7) and inserted into the sub-through hole 26 is fixed to the horizontal bar 31 (X1 in FIG. 8) provided closest to the eaves. Furthermore, the lap part 23 of the tile 1 arranged adjacent to the left is stacked and connected on the step connection part 3 of the tile 1 fixed to the base 30. At this time, the positioning protrusion 17 of the tile 1 placed on the step connection part 3 is placed in a locked state on the horizontal bar 31 (X2 in FIG. 8) (see FIG. 6), or Place it on the placement surface 31b (see FIG. 7). Furthermore, the connector 9 inserted into the sub-through hole 26 is fixed to the horizontal bar 31 (X1 in FIG. 8) provided closest to the eaves. Similarly, a plurality of roof tiles 1 constituting the first row are installed while being connected in the left-right direction.

Here, the tiles 1 constituting the first row are fixed to the base 30 using the sub-through holes 26 so that the eave-side tip edge 11 of the tiles 1 located closest to the eaves protrudes greatly from the building. It's for a reason. However, the tiles 1 constituting the first row may be fixed to the base 30 using the eave side through holes 6.

[Fixing tiles 1 constituting the second row]
Next, the plural tiles 1 constituting the second row are arranged at predetermined positions and fixed to the base 30. As shown in FIG. 8, the tiles 1 constituting the second row are arranged with the positioning protrusion 17 of the rear end 5 on the ridge side locked to the horizontal beam 31 (X3 in FIG. 8) (see FIG. 6) Alternatively, it is placed on the mounting surface 31b of the horizontal beam 31 (see FIG. 7), and the eave side front end 4 is placed over the ridge side rear end 5 of the tiles 1 in the front row. Further, at this time, the ridge side through hole 7 of the tile 1 placed on the eave side and the eave side through hole 6 of the tile 1 placed on the ridge side become coaxial on the horizontal beam 31 (see FIGS. As shown in FIG. 7), the eave-side front end 4 of the ridge-side tile 1 is stacked on top of the ridge-side rear end 5 of the eave-side tile 1 (front-rear lamination step). Furthermore, the connector 9 is inserted into the eave side through hole 6 and the ridge side through hole 7 arranged coaxially (see FIGS. 6 and 7), and the connector 9 is inserted through the ridge side through hole 7 and the eave side through hole 6. The connector 9 is fixed to the horizontal beam 31 (fixing step).

Furthermore, the lap part 23 of the tile 1 arranged adjacent to the left is stacked and connected on the step connection part 3 of the tile 1 fixed to the base 30. At this time, the positioning protrusion 17 of the tile 1 placed on the step connection part 3 is placed in a locked state on the horizontal bar 31 (X3 in FIG. 8) (see FIG. 6), or It is placed on the placement surface 31b (see FIG. 7), and the eave side front end 4 is placed over the ridge side rear end 5 of the tiles 1 in the front row. Further, the ridge side through hole 7 of the tile 1 placed on the eave side and the eave side through hole 6 of the tile 1 placed on the ridge side become coaxial on the horizontal beam 31 (see FIGS. 6 and 7). ), the eave-side front end 4 of the ridge-side tile 1 is placed over the ridge-side rear end 5 of the eave-side tile 1 (front-rear lamination step). Furthermore, the connector 9 is inserted into the eave side through hole 6 and the ridge side through hole 7 arranged coaxially (see FIGS. 6 and 7), and the connector 9 is inserted through the ridge side through hole 7 and the eave side through hole 6. The connector 9 is fixed to the horizontal beam 31 (fixing step). Similarly, a plurality of roof tiles 1 constituting the second row are installed while being connected in the left-right direction.

Furthermore, in the same manner as the above process, for the third row and subsequent rows, the plurality of roof tiles 1 are connected on the left and right and front and back and roofed at predetermined positions while repeating the front and back laminating process and the fixing process. That is, a plurality of tiles 1 arranged in multiple rows, where n is a natural number, are connected to the ridge side through-hole 7 of the tile 1 arranged in the nth row and the eave side of the tile 1 arranged in the (n+1)th row. Place the eave side front end 4 of the ridge side tile 1 on top of the ridge side rear end 5 of the eave side tile 1 so that the through hole 6 is coaxial with the eave side tile 1 (front and rear lamination process), and The connector 9 is inserted into the eave side through hole 6 and the ridge side through hole 7 arranged in the ridge side through hole 6, and the connector 9 passing through the ridge side through hole 7 and the eave side through hole 6 is fixed to the horizontal beam 31. (Fixing step) By this, a large number of tiles 1 are installed in multiple rows in a predetermined arrangement.

[Connector 9]
The connector 9 that fixes the tile 1 to the base 30 may be a member that is screwed onto the base such as a set screw or a screw, or a member that is fixed by being driven into the base such as a nail or pin. Preferably, it is determined by the material of the base 30. For example, when the base is a shaped steel such as a lightweight steel frame, tapping screws, screws, bolts, etc. are used as the connectors, and when the base is a wooden material such as square lumber or concrete panels (plywood for formwork). Set screws such as wood screws, nails, pins, etc. can be used. Furthermore, in addition to the connecting tool 9, an adhesive can be used in conjunction with the connector 9 to more firmly fix the connecting portions between the tiles and the connecting portions between the tiles and the base.

According to the above construction method, when fixing the tiles 1 from the second row onwards to the base 30, the tiles 1 arranged in a stacked manner in front and back are connected to each other through the eave side through hole 6 and the ridge side through hole. It is fixed to the base 30 through only one connector 9 inserted through the base 30. Therefore, one connector 9 can be used to fix each tile 1. Therefore, compared to the conventional construction method, the number of locations where the tiles 1 are fixed can be halved, labor-saving fixing work and shortened working time, and construction costs can be reduced by saving the number of connectors 9. can be reduced.

In addition, a connector inserted into the eave-side through-hole 6 provided close to the eaves side of the tiles 1 arranged in the back row is inserted into the ridge-side through-hole 7 of the tiles 1 in the front row and fixed to the base 30. Therefore, since the eaves side of the tile 1 to be stacked is fixed in a state where it is pressed against the tile 1 in the front row, the front end portion of the tile 1 stacked above, close to the front edge 11 of the eave side, is fixed to the base 30, and the upper It is possible to effectively prevent the tiles 1 from coming off due to strong winds.

Furthermore, since the tiles that are stacked on each other are fixed to the base via the connectors that pass through the laminated portions, the tiles in the stacked state can be fixed to the base while providing excellent connection strength. Therefore, it is possible to effectively prevent roof tiles stacked above from coming off due to strong winds.

(Other examples of tile 1)
In the above embodiments, a flat tile having a flat overall shape is shown as a tile, but the tile may also be a corrugated tile having a wavy cross-sectional shape in the left-right direction. Examples of corrugated roof tiles will be shown below based on FIGS. 9 and 10.

A ridge-side through hole 7 is provided on the side. This corrugated tile 1B has a ridge side through-hole 7 provided in a peak 41 at the center of the tile 1 in the front row when arranging the tiles 1 in the back row in a stacked state with respect to the tiles 1 in the front row. The tiles are arranged so that the eaves side through holes 6 provided in the step connecting portions 3 of the tiles 1 in the rear row are coaxially arranged. That is, the tiles 1 arranged in front and behind each other are arranged in a staggered manner, with the peak 41 in the center and the peaks 41A and 41B with seams being alternately located. Furthermore, a connector is inserted into the eave side through hole 6 and the ridge side through hole 7 which are arranged coaxially, and the connector is fixed to the base via the connector passing through the ridge side through hole 7 and the eave side through hole 6. Ru.

In addition, the corrugated tile 1B shown in FIG. A sub-through hole 27 is also provided on the rear edge 12 side of the ridge side as a preliminary through hole for inserting the connector. This corrugated tile 1B can be fixed to the base via a connector inserted through the sub-through hole 26 or the sub-through hole 27 in addition to the connector inserted through the ridge-side through hole 7.

The corrugated tile 1C shown in FIG. 10 has peaks 41 connected to both sides of a trough 42 provided in the center, and furthermore, on the outside of the ridges 42, there is a narrow bottom plate 43 divided into two at the center. The tile main body part 2 is formed in a shape that connects the valley parts 42A and 42B, respectively. The tile main body 2 shown in the figure has a rectangular shape in plan view, and has a stepped connecting portion 3 along the side edge 28 of one of the narrowly cut valleys 42A and 42B on both sides. At the same time, the side edge of the other valley part 42B is formed into a wrap part 23 that is laminated in a wrapped state on the step connection part of the tiles arranged adjacently. That is, the corrugated tile 1C having this shape has a structure in which the tiles 1 connected in the left-right direction are connected via the step connecting portion 3 at the opposing valley portions 42A and 42B. The trough portions 42A and 42B connected via the step connection portion 3 are configured to have the same external shape as the trough portion 42 in the center when connected to each other.

This corrugated tile 1B has a ridge-side through hole 7 provided in a valley 42 in the center of the front row tile 1 when the rear row tiles 1 are stacked against the front row tiles 1. The tiles are arranged so that the eaves side through holes 6 provided in the step connecting portions 3 of the tiles 1 in the rear row are coaxially arranged. That is, the roof tiles 1 arranged in front and behind each other are arranged in a staggered manner in which the central trough 42 and the jointed troughs 42A and 42B are staggered. Further, a connector is inserted into the eave side through hole 6 and the ridge side through hole 7 which are arranged coaxially, and the connector passing through the ridge side through hole 7 and the eave side through hole 6 is fixed to the base. In this corrugated tile 1C, the ridge side through hole 7 and the eave side through hole 6 are provided in the valleys 42 and 42A, so when connecting the front and rear tiles 1, it is necessary to connect the step connecting portion 3 of the valley 42A and the valley.
