Description

[Detailed description of the invention] [Industrial application field] In this invention, a small number of rows and columns of running water pieces are integrally formed into a single piece in a state of being laid, and tiles equivalent to several pieces at a time are formed. Related to roof tiles that can be laid.

[Prior Art] Conventionally, in order to tile a roof having a shape such as a gable, a ridge, etc., for example, in the same bank, a roof tile with an edge at one end is used as a roof start for the roof, and the size of the roof is increased. Adjust the roofing length by using a mixture of approximately rectangular ground tiles or, if necessary, rectangular tiles shorter than this one, and laying on the same bank for rain. Laying between adjacent tiles via a roofing section,
Moreover, the end of the roof is sewn through the roofing section using several types of tiles toward the upper ridge part by using a sleeve end tile with an edge, and further the ridge tile is placed on the ridge part at the top The laying work is being performed by connecting them continuously. In this case, the tiles are laid with various patterns such as a lattice-like pattern or a staggered pattern for beautifully finishing the appearance of the entire roof.

In addition to the materials used to form the roof tiles, other than those that fire clay like this roof tile, the cement was compressed and cured and solidified like a thick cement roof tile, and the asbestos was used like a slate roof tile. Some were formed using small pieces made of a thin metal plate such as copper, aluminum, stainless steel or the like, such as a color iron plate.

[Problems to be solved by the invention]

However, in each of the above-mentioned conventional tiles, several types of tiles (ground tiles) each having a predetermined size and formed into a substantially rectangular plane are manufactured one by one, and the tiles are overlapped with each other. Ascending through the roofing part arranged so that
Alternatively, since the tiles located in the lower row are laid one by one on the open board via the overlapping part, a lot of cost and labor are required for the production cost and the laying work.

In addition, among the above-mentioned conventional roof tiles, in particular, flat tiles formed of cement or slate may not be able to withstand the weight of the weight when the operator rides on the upper surface when laying on the roof, and cracks or chips may be generated. Because this is a structure that is superposed especially on the roofing part of the tiles adjacent to each other on the left and right,
There was no other choice but to reduce the wall thickness.

Simply increasing the thickness of the tile to address this and making the structure more robust would increase the weight of a single tile per unit area, which would be a high cost when laying roof tiles on a roof. It involved dangerous work in the place, was inconvenient to handle and transport, and had high costs. Moreover, when the roof tiles are laid and constructed on the roof, the thickness of the roof tiles increases due to the overlapping of the overlapping parts. Also one
Since the size of the tile body for each sheet is small and the laying area is small,
Roof tiles to be laid at once were inefficient and inefficient.

Furthermore, conventional roof tiles are formed to have a substantially uniform thickness, and no heat insulation means is provided on the back surface. The room was warmed up and the room became hot. On the contrary, in winter, the warm air from the room was directly cooled by the outside air and closed. And when it rained, the noise was noisy. In addition, when the back surface of the roof tile is formed in a substantially plate shape, the contact area of the roof with the ground plate or the like of the roof becomes large. In some cases, the water is easily absorbed by the suction due to the phenomenon, so that the water leaks through the back surface of the roof tile to cause leakage.

Thus, the present invention is to lay and construct a tile body corresponding to several tiles at once, thereby performing the laying work safely and efficiently, reducing the production cost and the laying construction cost, and reducing the thickness. In spite of the thinness, the structure becomes robust, and if the maker steps on the tile body during work and puts weight on it, the cracks and chips are reduced and the durability is improved, and the back surface of the tile body as a heat insulating means The purpose of the present invention is to provide a roof tile having a recess capable of being filled with an air layer or a heat insulating material, which can sufficiently secure a heat insulating function, has a small leak of rain, and has a high sound insulation function against rain sound during rainfall. I do.

[Means for solving the problem]

The present invention has been made in view of the above points, and a tile body is integrally formed by laterally displacing an upper tile component and a lower tile component, and the front and back surfaces of the upper tile component and the lower tile component are formed. In the roof tile provided with the roofing portion substantially symmetrically and laterally displaced, a peripheral reinforcing rib is provided on the back surface of the tile main body, and a desired width and a desired length are provided in the inner region of the peripheral reinforcing rib. A roofing overlap portion is provided to integrally form the upper tile component and the lower tile component, and other reinforcing ribs are provided vertically and horizontally, and the reinforcing rib, the peripheral reinforcing rib, and the roofing overlap portion are provided. The roof tile body except for the installation location is formed in a thin portion having a small thickness, and a concave portion surrounded by the peripheral reinforcing rib is formed on the back surface of the thin portion.

[Action]

Since the tile body is integrally formed with an upper tile component and a lower tile component that are approximately rectangular in plane via the overlapping part, for example, when roofing a gable roof, first, for example, symmetrical By overlapping the roofing portions provided in the above, roofing bodies corresponding to several tile bodies are roofed at once in several rows and several columns from the lower edge of the field board via roofing. Then, the lower edge of the lower tile component located in the lower row of the new tile main body to the desired width from the upper edge of the upper edge portion of the upper tile component located in the ascending row of the already-roofed tile main body is joined to the building in order. For example, they are laid in a zigzag pattern.

At the time of roofing, the tile body is formed integrally with the upper tile component part and the lower tile component part via the back side of the horizontal overlapping overlapping part of the desired width and desired thickness, and the tile body has a surrounding Since the reinforcing ribs and the reinforcing ribs including the overlapping overlapping portion are provided in the inner region of the reinforcing ribs and the peripheral reinforcing ribs vertically and horizontally, a thin-walled thin portion is formed on the tile main body except for a place where the reinforcing ribs are installed. Even when the main body is made lighter, the structure of the roof tile body becomes robust without generating chips or cracks.

In addition, since a recess surrounded by the surrounding reinforcing ribs was formed on the back surface of the thin portion of the tile body, this recess becomes an air layer when the tile body is laid on the roof, and a heat insulating material is provided in the recess. Can be packed. Therefore, a sufficient heat insulating function can be ensured, and it is possible to spend comfortably in the summer or winter, and it is possible to isolate the sound of rain during rain. In addition, a concave portion is formed on the back surface of the tile body, so that the contact area with the roof is small, and the capillary phenomenon from the gap formed in the tiled portion of the tile body is prevented. Bleeding on the back side is prevented.

3A ₁ , 3A ₁ ; 4B ₁ , 4B ₁ are provided at different displacements l ₃ , for example, about 5 to 25 cm in a plane, as shown in FIG. 1 and FIG. As a result, when the tile main bodies 1 adjacent to each other are laid on each other, rain is reliably performed.

5 is a plurality of grooves provided in the roofing portion of the upper tile component 1A in a horizontally long manner, and 6 is short and horizontally elongated in the upper edge of the projecting side of the lower tile component 1B also located in the lower row. The grooves 5 and 6 are provided on the other roof tiles
Thatch. Grooves 5 and 6 are used when
According to 5,6, the roofing portions of the tile bodies 1,1 which are laid on top and bottom are made to have good waterproofness.

On the back side of the tile main body 1, reinforcing ribs are provided vertically and horizontally integrally in substantially the periphery and the inner region surrounded by the periphery (see FIG. 5). As the reinforcing ribs, a lateral reinforcing rib 7a provided substantially over the entire upper edge of the upper tile forming part 1A located in the ascending row, and a lateral reinforcing rib provided substantially over the entire lower edge of the lower tile forming part 1B located in the descending row Reinforcement ribs 7b, vertical reinforcing ribs 7c, 7d provided at the outer end of the upper tile component 1A, and vertical reinforcing ribs 7e, 7f provided at the outer end of the lower tile component 1B, the surrounding reinforcing ribs. It is formed. Of these, the vertical reinforcing ribs 7c, 7e
Are formed slightly thinner than the opposed vertical reinforcing ribs 7d, 7f. This means that the roof tiles 3A, 4A are attached to the roof tiles 3B, 4B provided on the other side of the tile body 1 adjacent to one side of the upper tile tile 1A located in the ascending row and the lower tile tile 1B located in the row below. This is for polymerization. The desired with a desired width l ₁ in Fukiai Align the point where the upper edge of the lower tile configuration section 1B in the inner region of the reinforcing ribs surrounding located lower edge and the lower row of the upper tile configuration unit 1A located above the line The above-mentioned overlapping overlapping portion 2 as a reinforcing rib having a thickness l ₂ , for example, about 1.2 to 4.5 cm is arranged.

The thickness of the roof tile body 1 is about 7 mm, excluding the places where the reinforcing ribs are provided.
About 4.5 ~ by being formed in the thin part U, U '
Even if the weight is reduced to about 5.6 kg / cm ² , the structure is robust without generating chips and cracks, and the work can be done safely and securely without falling because the laying work at high places is lightweight and easy to handle.
Moreover, the thin portion U of the upper tile component 1A and the lower tile component 1B,
Since the concave portions O and O 'surrounded by the peripheral reinforcing ribs are formed on the back surface of U', the concave portions O and O 'become air layers when the tile body 1 is laid on the roof Y described later. Insulating function can be achieved by filling the recessed portions O and O 'with a heat insulating material (not shown) to form a storage portion. Sound insulation. When the tile body 1 is laid on the roof Y, the tile body 1
By forming the peripheral reinforcing ribs provided on the back surface and the reinforcing ribs including the roofing overlapped portion 2 provided vertically and horizontally in the peripheral reinforcing ribs at thinner portions U and U 'having a smaller thickness, Since the recessed portions O and O 'are formed on the back surface to form an air layer, when the tile body 1 is laid on the roof Y, the area of the tile body 1 that directly contacts the field board 10 of the roof Y is conventionally reduced. And the capillary action does not work. Therefore, even if rainwater tries to infiltrate from the gap formed between the roofing portions of the tile body 1 for example, the rainwater does not seep into the back surface of the tile body 1 and the rainwater leaks out. Is prevented. It should be noted that, although not shown, if a reinforcing bar such as a fiber reinforced plastic is provided inside the reinforcing ribs, the structure can be further strengthened.

Numeral 8 denotes mounting holes appropriately provided on the upper edge of the roofing portion corresponding to the upper tile component 1A located in the upper row and the lower tile component 1B located in the lower row. (Not shown), the tile body 1 is attached to the roof board 10 of the roof Y via the roofing material 9.

One embodiment of the present invention is configured as described above, and the laying method and rainwater drainage method will be described below together with the operation.

For example, in order to lay and construct the tile body 1 on a roof Y having a gable shape or the like, first, as is well known, the entire surface of the field board 10 is covered with a roofing material 9 for waterproofness.

Then, as shown in FIG. 1, the tile body 1 starts to be roofed from the end located at the lowest stage (corresponding to the first and second rows from the bottom of the figure in this embodiment) of the eaves of the baseboard 10.

The roof area corresponding to the conventional tile body of approximately 6 sheets in two rows and three columns by one tile body 1 by driving nails into the mounting holes 8, 8, 8 of the tile body 1 Can be attached to the base plate 10 via the roofing material 9 at one time.

Then, in the same row of the first and second rows, the roof tiles 3B and 4B provided at one end of the upper tile component 1A and the lower tile component 1B of one tile main body 1 attached according to the procedure described above. Similarly, by driving nails into the plurality of mounting holes 8,
The roofing sections 3A and 4A at the opposite ends of the adjacent other tile body 1 attached to 10 are overlapped and roofed. In this case, if necessary, the concavities 3A ₁ , 4A, 4A;
4A ₁ ; 3B ₁ , 4B ₁ are superimposed, and the tile bodies 1 adjacent to each other are laid. In this manner, in the same row, the tile main body 1 is sequentially laid in substantially the entire area in the left-right direction. At this time, the upper and lower edges of the upper tile component 1A and the lower tile component 1B of the adjacent tile body 1 and the roofing portions 3B, 4B
If the leading edges of the roofing portions 3A and 4A are made to abut against each other, the positioning of the adjacent tile bodies 1 can be performed accurately and easily.

In the same row, as for the remaining space located at the roofing start end and the roofing end, one tile body 1 with different usability is cut to a sufficient length from the end as shown by the imaginary line in FIG. By preparing the first tile body 1 'and the last roof tile body 1 ", respectively, according to the site conditions, similarly, the first and second rows of the roofing sections 3A, 4A; 3B, 4B are overlaid. Roof it up.

At this time, a lateral reinforcing rib 7 is provided around substantially the entire back surface of the tile body 1.
a, 7b and vertical reinforcing ribs 7c, 7d, 7e, width approximately l ₁ in and the inner region of the peripheral reinforcing rib around the reinforcing rib is provided comprising a 7f
, And the and for Fukiai Align polymerization unit 2 of the thickness l ₂ is provided horizontally when (FIG. 5, cf. FIG. 9), the operator to the laying work of the tile main body 1, in FIG. 2 When the weight is applied on the tile body 1 in the direction of arrow a, the tile body 1 is provided with the horizontal reinforcing ribs 7a, 7b and the vertical reinforcing ribs 7c, provided substantially all around the rear surface.
7d, 7e, 7f is reinforced vertically and horizontally by the perimeter reinforcing rib composed of
Since the cross-section is formed in a substantially Z-shape, the upper tile component 1A and the lower tile component of the tile main body 1 excluding the locations where the peripheral reinforcing ribs and the reinforcing ribs such as the overlapping overlapping portion 2 provided in the inner region are installed. By forming a thin portion U, U 'with a thickness of about 7 mm with 1B,
When the weight is reduced to about 4,5 to 5.6 kg / cm ² , the tile body 1 and the roofing parts 3A, 3B; 4A, 4B thinner than the tile body 1 are not damaged or chipped, and the load is reduced. And structural robustness against tensile forces. Although this is not shown, the structure becomes more robust when reinforcing bars are arranged inside the respective reinforcing ribs.

Thereafter, the roof of the tile body equivalent to six sheets is formed by the same procedure using one tile main body 1 having the two rows of the upper tile component 1A and the lower tile component 1B on the third and fourth rows from the eaves. The area is laid in the left and right directions at once. At this time, the lower edge portion of the upper lower tile component portion 1B in the third row located on the third row is covered with a desired width to the upper edge portion of the upper tile component portion 1A in the second row from the eaves, and the rain is performed ( (See FIGS. 1 and 2).

In this manner, the entire roof Y is laid in a staggered pattern using the tile body 1 from the inclined surfaces on both sides of the ridge portion toward the ridge portion, and an adhesive material such as mortar, cement, or the like is provided in the gap abutting in the ridge portion. To fill the roof tiles (not shown)
The laying work is completed by closing with the.

If vertical 42.5cm in the laying, Fukiai Align area indeed roof Y in the case of the use of the tile main body 1 of the lateral 64.6cm about the size, the use of the tile main body 1 of the 15 sheets approximately per 3.3 m ²葺Can be adjusted, and the weight of the tile body 1 is 4.5
Approximately 5.6 kg / cm ² , making it economical and efficient in laying work. In addition, laying work on a high place such as a roof can be performed safely and reliably without danger of falling.

In addition, on the back surface of the thin portions U and U 'of the upper tile component 1A and the lower tile component 1B of the tile main body 1, peripheral reinforcing ribs, that is, horizontal reinforcing ribs 7a and 7b and vertical reinforcing ribs 7c and 7d; , 7f, and recesses O, O ′ surrounded by reinforcing ribs provided in the vertical and horizontal directions of the roofing overlap portion 2 and the like in these inner regions to form a field board 1 of the roof Y.
0, so that the recessed portions O and O 'can serve as an air layer to exhibit a heat insulating function, or can be used as a storage portion for packing a heat insulating material (not shown). Sufficient heat insulation can be secured. Therefore, even if the roof tiles are warmed by direct sunlight in summer, the room is not directly heated, so it does not become hot, and in winter, the warm air from the room is not directly cooled by the outside air. So warm.

Further, since the recessed portions O and O 'are formed as described above, the rain sound during rainfall is quiet because an air layer or the like is formed and the sound is blocked.

In addition, the tile body 1 is formed in thin portions U and U 'except for the locations where the peripheral reinforcing ribs and the reinforcing ribs including the overlapping overlapping portions 2 provided vertically and horizontally in the inner region of the peripheral reinforcing ribs are formed. Since the contact area for forming the recesses O and O 'and contacting the roofing material 10 and the like of the roof Y is smaller than before, for example, when the tile body 1 is laid on the roof Y, Capillary action is prevented even if rainwater tries to flood through the gaps formed in the polymerized portion of the water. Therefore, the amount of rainwater seeping into the back surface of the tile main body 1 is extremely small as compared with the related art, and no rain leakage occurs.

And an upper tile component located in the upper row of one tile body 1
1A and the lower tile component 1B located in the lower row are approximately l ₁ in width, for example.
Since it is integrally formed through the roofing overlapping section 2 of about 0.5 to 5 cm, rain does not leak and permeate into this roofing overlapping section 2, so that the rain action during rainfall is ensured and the upper tile configuration The alignment between the section 1A and the lower tile forming section 1B can be performed exactly at once. In addition, the tile main body 1 is substantially symmetrically and laterally displaced to the front and back surfaces at both ends of the upper tile constituent part 1A and the lower tile constituent part 1B located in the ascending and descending rows, and the roofing parts 3A, 4A; 3B, 4B
When the adjacent tile bodies 1 are laid on each other in the left-right direction, the shingled portions 3A, 3B; 4A, 4B
As it is displaced with a length of about 5 to 25 cm as ₃ and does not coincide with one location in the vertical direction, rainwater is drained during rainfall without concentrating on the roofing location, and the roofing sections 3A, 3B; 4
The rain break in A and 4B is assured, and there is no water leakage or leakage.

See Figure 0).

22 is the ascending and descending running water pieces 20a, 20b, 20c; 21
a, 21b, 21c are a plurality of grooves extending longitudinally from the lower edge of each of them to separate them from each other. Grooves 22, 22 defining small pieces 21 a, 21 b, 21 c substantially coincide with each other via roofing overlapping portion 2, and upper ends of lower grooves 22 substantially coincide with lower edges of upper tile component 1 </ b> A located in the upper row. Stretching to do.

Reference numeral 23 denotes two tiles on the back surface of the upper tile component part 1A and the lower tile component part 1B that form the tile main body 1 in the inner region of the surrounding reinforcing ribs, two at the top and the other at the top of the roofing overlapped part 2. The vertical reinforcing ribs 23, 23 are formed so as to have a substantially Z-shaped cross section vertically through the roofing overlapping portion 2, and are tiled similarly to the above-described embodiment. The main body 1 includes peripheral reinforcing ribs provided on the back surface thereof, that is, horizontal reinforcing ribs 7a and 7b and vertical reinforcing ribs 7c and 7d; 7e and 7f, a roofing overlap portion 2 provided vertically and horizontally in an inner region thereof, and a vertical reinforcing rib. Rib 23
By forming the thin portions U, U 'at locations other than the installation location, the concave portions O, O' are formed to form an air layer as a heat insulating layer, or in the concave portions O, O ' Insulation material is packed (see Fig. 14).

In the second embodiment, the small pieces of running water 20a, 20b, 20c; 21a, 21b, 21c in two rows and three columns are partitioned on the surface of the upper tile component 1A and the lower tile component 1B of the tile main body 1. Groove 2
Since a plurality of longitudinal reinforcing ribs 23 are alternately arranged above and below the horizontally long overlapping overlapped portion 2 as reinforcing ribs so as to substantially coincide with 2 (see FIG. 14). In particular, when the load of the worker is applied to the thin portions U and U 'formed thin by providing the groove 22 on the surface of the tile body 1, for example, in the direction shown by the arrow A in FIG. As shown in the figure, the roofing overlap portion 2 is entirely dispersed in the directions indicated by arrows a ₁ and a ₂ and the plurality of longitudinal reinforcing ribs 23 in the directions indicated by arrows a ₃ and a ₄ . Further, when a tensile force acting in the opposite direction to the load acts on the tile body 1, the peripheral reinforcing ribs and the overlapping overlapping portion 2 in the inner region thereof and the vertical reinforcing ribs 23 exhibit rigidity in cooperation with each other. There is an effect different from that of the first embodiment in that the structure is made robust by preventing chipping.
